Filed:

Jun 9, 1992

Appl. No.:

7/896067

Inventors:

Charles E. Black - Mount Prospect IL

Assignee:

Indak Manufacturing Corp. - Northbrook IL

International Classification:

H01C 1300

US Classification:

338 50

Abstract:

The resistor unit comprises resistors connected to electrical terminals secured to an insulating plate to which first and second legs of a spring sheet metal mounting clip are secured for insertion through an opening in a supporting wall. The legs are bent forwardly from a rear member and are formed with first and second spring latching members including ramp portions bent laterally from the legs, shoulder portions bent inwardly from the ramp portions for wedging engagement with edge portions of the wall, and front end portions bent forwardly from the inner ends of the shoulder portions. A soft resilient expanded rubber gasket is mounted on the plate for sealing engagement with a rib projecting forwardly from the wall around the opening. The spring force produced by compression of the gasket is counterbalanced by the wedging action of the shoulder portions, so that rattling is prevented. The legs are inserted with an interference fit into opposite end portions of the opening.

Abstract:

Apparatus for high speed bulk magnetic encoding of lottery tickets passes a web of tickets by an encoding apparatus which supports plural skates each having wheels or rollers which ride along the surface of the web to provide a controlled gap between the web and a magnetic write head. Also included on the skate are a magnetic read head and an inkjet print head. After encoding and printing, the perforations in the web are bursted, and the web is sliced into individual magnetically encoded lottery tickets.

Appl. No.:

6/813771

Inventors:

Charles E. Black - Mount Prospect IL
Raymond T. Halstead - Wheeling IL

Assignee:

Indak Manufacturing Corp. - Northbrook IL

International Classification:

H01R 448

US Classification:

439 77

Abstract:

Compressible metal spring washers are mounted around the shank portions of terminal rivets and are clamped against thin conductor laminae of a flexible printed circuit having a resilient resinous plastic base lamina, clamped by the rivets against a relatively rigid plastic terminal supporting member. Each washer has a central dished portion, a reversely dished peripheral portion, and a smoothly rounded annular bulging portion therebetween for engaging one of the thin conductor laminae, without cutting into the laminae. The spring washers obviate any looseness of the terminal rivets due to dimensional variations, shrinkage with age, and temperature variations.

Filed:

Feb 15, 1994

Appl. No.:

8/196396

Inventors:

Charles E. Black - Mount Prospect IL

Assignee:

Indak Manufacturing Corp. - Northbrook IL

International Classification:

H01H 906

US Classification:

200 6186

Abstract:

The apparatus, which controls the operation and speed of an electrical blower motor and the operation of a vacuum operated recirculation control device, comprises a vacuum switch combined with an electrical switch having a rotary shaft and fixed and movable contacts whereby rotation of the shaft controls the operation and speed of the blower motor. The shaft is pushable rearwardly and is spring-biased forwardly for operating the vacuum switch whereby vacuum is selectively supplied to the recirculation control device for switching between outside air and recirculation of air. A push-push latching mechanism is provided for alternately latching the vacuum switch in one position and releasing the vacuum switch for return movement to its other position.

Appl. No.:

6/689830

Inventors:

Charles E. Black - Mount Prospect IL
John W. Habecker - Zion IL

Assignee:

Indak Manufacturing Corp. - Northbrook IL

International Classification:

H01H 1500
H01H 100

US Classification:

200 16C

Abstract:

The switch has at least one contact plate, mounted on the inner side of an insulating wall forming one side of a casing. The contact plate has a contact rail or some other contact element which is engageable by a contactor on a movable carriage within the casing. The contact plate has a mounting hole surrounded by a circular flange extruded from or otherwise formed in one piece with the contact plate. A terminal bar is mounted against the outer side of the insulating wall and is connected to the contact plate by a terminal rivet, extending through the circular flange with an interference fit to establish good electrical contact therewith. The rivet also extends through an opening in the insulating wall and a mounting hole in the terminal bar. The swaging of the rivet causes the shank of the rivet to bulge outwardly, thereby expanding the circular flange and establishing a heavy interference fit between the flange and the swaged rivet, to establish and maintain low-resistance electrical contact between the flange and the rivet. Initially, the flange is preferably tapered, but is expanded by the bulging of the swaged rivet.

Assignee:

Bally Manufacturing Company - Chicago IL

International Classification:

G06K 900
G06K 978

US Classification:

235454

Abstract:

An optical card reader for reading marks made on the face of a preprinted card utilizes a video camera and a memory device to capture and store an image of at least a portion of the card. Positioning indices are printed on the card, and the reader has stored therein information defining possible locations of valid marks relative to the positioning indices. The centroids of the positioning indices on the cards are determined to define the possible locations of valid marks on the cards. The densities and centroids of the marks located in the possible locations are analyzed to determine if a valid mark is present.

International Classification:

F16K 2500

US Classification:

251176

Abstract:

A vacuum control valve comprising a body having a valve surface with a plurality of valve ports extending through the body from such surface, a soft resilient valve member having a control surface slidable along the valve surface and formed with passage means for selectively establishing communication with the valve ports, a movable carriage for receiving and supporting the valve member, and means for moving the carriage along a path substantially parallel with the valve surface, the soft resilient valve member having a soft resilient compressible rear portion formed integrally with such valve member on the opposite side thereof from the control surface, the valve member being confined between the carriage and the valve surface with such soft resilient compressible rear portion in a compressed condition for exerting resilient pressure between the control surface of the valve member and the valve surface of the body, the soft resilient compressible rear portion comprising a pattern of fins alternating with recesses on the valve member, such fins engaging the carriage.

Assignee:

Indak Manufacturing Corporation - Northbrook IL

International Classification:

B60K 2600

US Classification:

180103R

Abstract:

The disclosed safety system is particularly applicable to walk-behind lawn mowers of the type having a drive including a control, movable between drive and neutral positions. The safety system includes a drive switch, movable between drive and neutral positions. The safety system also includes a deadman control, biased toward an off position and manually movable to an on position. The deadman control operates a deadman switch between off and on positions. The lawn mower includes a drive motor having a safety circuit for disabling the motor. The drive switch and the deadman switch are connected into the safety circuit and are provided with contacts for disabling the motor when the drive switch is in its drive position and the deadman switch is in its off position. Such contacts are also operative to disable the motor when the drive switch is in its neutral position and the deadman switch is in its on position. In a modified construction, the safety system also includes a starting interlock switch operable by the starting device for the motor.
