Appl. No.:

10/823193

Inventors:

John Lawrence - Landenberg PA, US

International Classification:

A46B001/00
A46B011/06
A47L013/22

US Classification:

401289000, 401286000, 40118800R

Abstract:

A device capable of delivering a continuous or intermittent amount of common paint or paint-like material to a surface to be painted utilizing a standard, off the shelf paint brush, the novel use of which allows the operator the ability to continuously paint with the brush and not having to break the work sequence of painting by continuous interruption of having to reload the brush by dipping it into a paint can, the component parts of which consists of a stationary platform which is centrally mounted on the brush in between the area of the brush handle and bristles, this being securely held in place by a pair of lateral brush clamps, these designed to accommodate a variety of brush sizes and widths, and or as an alternative, a broad band of flexible material having a series of central perforations, longitudinally and also having at its ends, reusable, self-adhesive material, and a rigid tube that is mounted on the top of the stationary platform or, alternately, held in place centrally by the perforations in the flexible banding, the tube acting as a conduit for paint, which is delivered from a remote source to the rigid tube via another flexible connecting tube, the paint being pumped or otherwise delivered to the rigid tube terminus and thus flowing onto the bristle portion of the brush, the paint flow being properly distributed on the bristles by an attached apron, which also aids in reducing paint drippings, all of which allows the painter to continuously apply paint to a surface without interruption or increased fatigue.

Assignee:

AMP Incorporated - Harrisburg PA

International Classification:

H01R 1101

US Classification:

339 95R

Abstract:

Multi-contact connector for connecting wires to terminal pads on a circuit board comprises a housing having a trough-like opening extending into its circuit board receiving face. Terminal receiving cavities extend into the circuit board receiving face at spaced-apart intervals. The terminals are U-shaped and have wire-receiving slots extending inwardly from one end. A leaf spring is provided at the other end for contacting a terminal pad. Wire-admitting slots are provided in the housing and extend into the circuit board receiving face and the adjacent sidewalls. In use, a wire is positioned in the wire-admitting slots and the terminal is then inserted into the cavity. The wire is received in the wire-receiving slots and thereby connected to the terminal. When the circuit board is inserted into the trough-like opening, a spring contact on the terminal will engage a terminal pad.

8/798437

Inventors:

John S. Lawrence - Kemblesville PA

International Classification:

B08B 302

US Classification:

239722

Abstract:

A portable automobile undercarriage washing/cleaning device consisting of an inverted bowl-like body portion featuring a water spray nozzle on the top face and a connection for a rigid, non-flexible water pipe on the side of the body, the water pipe ending in a water control valve, and casters underneath of the body and attached to the body, which when all of the components are connected together and secured to a standard garden-type hose, results in a pressurized water spray pattern capable of being delivered to the undercarriage of an automobile, or other wheeled vehicle, the pressurized water spray being used to remove accumulated mud or road salt from the undercarriage of the vehicle, which was deposited on the undercarriage of the vehicle under normal driving conditions on debris-ladened readways and effecting the rapid removal of the debris from the undercarriage and its related structural members.

Inventors:

John S. Lawrence - Kemblesville PA

International Classification:

A61C 504

US Classification:

433 90

Abstract:

A dental syringe for filling cavities in teeth with dental filling materials and can be dispensed into a tooth cavity in measured in increments of all or a portions of one or two-predetermined quantities of filling material. The syringe is composed of an elongated body barrel having two hollow, contiguous parallel shafts and a disposable chamber removably attached to the barrel and having two hollow contiguous parallel shafts which are coextensive and continuous in precise axial dimensions as the shafts in the barrel.

John S. Lawrence - Kemblesville PA

International Classification:

B05B 300
B05B 318

US Classification:

239722

Abstract:

An improved portable automobile undercarriage washing/cleaning device consisting of an ovoid, bowl-like body portion on the top surface of which is centered a detachable water spray nozzle and an accompanying nearby small tube, which itself connects the interior fluid chamber/reservoir, the fluid consisting of a mixture of detergent and water, with the exterior of the body, the same tube directing a pressurized mixture of detergent and water into the water spray pattern emanating from the nozzle, the mixture then being admixed with the spray, the whole of which when attached via a side connection on the body, to a rigid, non-flexible water pipe, which is itself connected to a garden-type hose via a pistol-grip water control valve, produces a pressurized water spray pattern capable of removing accumulated road salt and debris deposited onto the underside of an automobile or other wheeled vehicle and effecting a rapid removal of the debris from the undercarriage of the automobile or other wheeled vehicle and its related structural members.
