US Patent:

46259368, Dec 2, 1986

Filed:

Jun 6, 1983

Appl. No.:

6/501202

Inventors:

Edward L. Hadden - Mechanicsburg PA

Assignee:

Sine Products Company - Mt. Clemens MI

International Classification:

F16M 1300

US Classification:

248544

Abstract:

A flexible support and carrier assembly for supporting an associated accessory is shown having a plurality of sequentially arranged body-like segments, the segments being arranged with respect to each other for articulated motion as between adjacent segments, the plurality of sequentially arranged body-like segments define an elongated articulated structure having first and second ends, a spring operatively carried by the articulated structure resiliently resists while permitting articulated motion as between adjacent segments to occur in a first direction of articulation, the spring also resiliently urges the adjacent segments to experience articulated motion in a second direction of articulation opposite to the first direction, and guard portions carried at least by certain of the segments, the guard portions functioning to prevent the unintentional incursion of unrelated objects into spaces between the adjacent segments when experiencing articulation.

Appl. No.:

5/522925

Inventors:

Richard Kay Dennis - Etters PA
Edward Leal Hadden - Mechanicsburg PA

Assignee:

E. I. Du Pont de Nemours and Company - Wilmington DE

International Classification:

H05K 104

US Classification:

317101CC

Abstract:

A retaining frame for forming interconnections between contact pads on a flat leadless I. C. package and corresponding pads on a parallel mother board so that when the package is moved toward the mother board and into the frame, contacts in the frame are compressed and contact surfaces are biased toward and moved along the contact pads on the package and board to form positive wiped electrical connections.

Appl. No.:

6/655562

Inventors:

Edward L. Hadden - Mechanicsburg PA

International Classification:

B21D 908
B25B 712

US Classification:

72410

Abstract:

A diminishing arm toggle linkage has the work site within the toggle geometry and thereby provides exponential force enhancement. In preferred embodiments the mode of operation shifts on demand from a light-load-pivoting mode to a heavy-load-rolling element mode thereby easing operation and reducing friction and wear so as to provide prolonged durability and continuing dimensional accuracy. When the toggle linkage is embodied in a crimping tool an optional anti-reversing ratchet assembly prevents the tool from opening during use until a crimp is completed.

Appl. No.:

7/362799

International Classification:

F16H 2518
B21D 908
B26F 136

US Classification:

74107

Abstract:

A new compact linkage for translating rotary input force to amplified linear output force includes two force applying members which move apart relatively during operation of the linkage. A strut is pivotally attached at one end to each of the force applying members; the struts extend towards each other with a space between their free ends. Each strut has a bearing surface at its free end. A cam-roll member is interposed between the bearing surfaces of the struts and includes cam surfaces in contact with the bearing surfaces. When the cam-roll member is rotated by a lever attached thereto, it translates the rotary input force from the lever into linear output force by a rolling action of the cam-roll member against the bearing surfaces of the pivoted struts. The linkage is markedly more efficient in force translation and transmission than pivoting toggle linkages typical of the prior art.

Appl. No.:

5/660180

Inventors:

Robert Franklin Evans - New Cumberland PA

Assignee:

E. I. Du Pont de Nemours and Company - Wilmington DE

International Classification:

H01R 306

US Classification:

339 14R

Abstract:

An electrical connector for a flat multi-conductor transmission cable includes a cable terminating face, a parapet having a plurality of V-shaped grooves and a scalloped top extending from the face, a bus strip engageable with the face, and a cover. Also, a method for terminating the cable includes severing an insulated sheath of the cable intermediate its end, sliding the severed insulated end along a length of the conductors to expose the shield and signal conductors, severing the signal conductors, folding the insulated end of the transmission cable back along its length over a bus strip, and engaging the shield conductors with the bus and the signal conductors with electrical terminals on the face of the connector.

Appl. No.:

5/576450

Inventors:

Richard Kay Dennis - Etters PA

Assignee:

E. I. Du Pont de Nemours and Company - Wilmington DE

International Classification:

H05K 112

US Classification:

339 17CF

Abstract:

A connector block for forming interconnections between contact pads on a flat leadless IC package and corresponding pads on a parallel circuit board. The block carries a number of terminals each having a collapsible linkage such that when the package is moved toward the circuit board, collapse of the linkage is controlled by a guide surface and wiped pressure connections are formed between the terminals and pads on both the substrate and the circuit board.
