39964280, Dec 7, 1976

Filed:

Mar 17, 1975

Appl. No.:

5/558585

Inventors:

Danilo P. Buan - Fremont CA
Richard F. Kingsbury - San Jose CA

Assignee:

Litronix, Inc. - Cupertino CA

International Classification:

H01H 1370
H01H 106

US Classification:

200 5A

Abstract:

A switch assembly having a plurality of movable elements for connection with underlying fixed contact elements carried by a base member, the movable insulative support sheet mounted on the base member. Each movable element is spaced by an electrically insulative sheet carried by the support sheet, and has a pair of opposed tines extending through the support sheet received in base member apertures. The movable elements may be dome shaped, partially cylindrical in shape, and span a plurality of the fixed contact elements.

Richard A. Kingsbury - Pleasanton CA

Assignee:

Quest Transportation Products, Inc. - San Jose CA

International Classification:

B60S 902

US Classification:

2807661

Abstract:

A trailer landing gear lifting apparatus (100) for raising and lowering landing gear (10) of a trailer (30) has a motor (136) fitted to a motor plate (134) which is affixed to a modified conventional gear housing cover (130) of a trailer landing gear assembly (10). The motor (136) has a motor gear (154) affixed to a motor shaft (156) by a roll pin (158). The motor gear (154) engages a drive low gear (142) of a generally conventional gear system (136). A spacer on a drive shaft 138 locks the gear system (136) such that the drive low gear (142) engages a driven low gear (146). A key switch (172) controls a pair of solenoids (170) to selectively provide power to the motor (136) for raising and lowering the legs (14) of the landing gear assembly (10).

International Classification:

H05K 330

US Classification:

29841

Abstract:

An alpha-numeric display device having a modular structure for placement side-by-side in vertical and horizontal formats to present symbols, words and phrases. The device functions as a stand-alone peripheral, appearing to a controller, such as a microprocessing device, as a random access memory. In particular, the device is operative to receive a standarized 7-bit ASCII code and to translate it to a multiple segment display whereby it can be continuously presented. The device provides a small, relatively low-cost alphabet and number display with a built-in electronic interface to a microprocessing unit permitting word communication to be incorporated into compact equipment, such as hand-held terminals and portable display devices. Complex interface circuitry is compactly packaged in a modular device by utilization of hybrid integrated circuit technology in which a multiple layer substrate provides interconnection between display units and semiconductor integrated circuit chips on opposing sides of the substrate. A multiple step PTF silkscreen printing process permits construction of a two-sided, compact display device with extremely thin, high resolution printed interconnections.

Assignee:

Quest Transportation Products, Inc. - Pleasanton CA

International Classification:

B60S 904

US Classification:

2807661

Abstract:

A trailer landing gear lifting apparatus (100) for raising and lowering landing gear (10) of a trailer (30) has a wrench (102) connected by an air hose (102, 222) to an air supply line ((212) and, optionally, to an air tank (210). An attachment bracket (104), a keeper arm (106) and a wrench bracket (110) optionally secure the wrench (102) to a pair of I beams (112) of the trailer (30) such that the wrench (102) is affixed to the trailer (30).
