Title: Electromagnetically Actuated Valve
Inventor: MORINIGO FERNANDO B
IPC: F01L9/20
Filed: 1993-10-05
Abstract: An electromagnetically actuated valve (10) is disclosed having an upper electromagnetic element (32) and a lower electromagnetic element (34), each having a toroidal or annular configuration with a U-shaped cross section and in mirrored relationship with each other.  The elements define a central chamber (26) and a central channel (30).  A core element (16) has an annular horizontal cross section and is disposed intermediate the upper (32) and lower (34) electromagnetic elements.  A connecting plate (18) connects the core element (16) to a valve stem (22).  A spring (20) biases the core element (16) to a neutral position.

Title: Electrical connector with improved ejectors and assembly
Inventor: NOSCHESE ROCCO J
IPC: H01R13/633
Filed: 1994-05-20
Abstract: ABSTRACT            An  electrical  connector  is  provided  with  a  housing, electrical contacts mounted to the housing, and ejectors pivotally mounted to the housing.  The ejectors have pivot posts that extend in the same direction and spaced ejecting fingers.  The pivot posts are axially slid into pivot holes at the edge of the housing along a first direction. The ejectors are then rotated in a second direction orthogonal to the first direction with the fingers being received in finger holes in the housing to thereby prevent the ejectors being inadvertently disconnected from the housing.  The fingers  and  finger holes  extend,  at  least  partially, between adjacent contact receiving holes in the housing.          Detent locating of the ejectors is provided at an open position and a closed position.   The housing includes blocking projections to prevent connection of an integrated circuit chip other than in a predetermined position.

Abstract: A method is provided for enhancing corrosion resistance of metallic substrates by forming an elemental aluminum or aluminum alloy coating in a vacuum and then exposing the coated substrate to a plasma that includes oxygen  or  halogen  moieties.    The  plasma  exposure  is conducted at evacuated pressures and forms a corrosion resistant film for the substrate.  This corrosion resistant film is formed quite quickly, without the use of corrosive acids (as in prior art anodizing processes), yet provides significantly improved corrosion resistance with respect to air exposed, aluminum coated substrates.

Inventor: HART JAMES E
IPC: B60T13/66
Filed: 1995-11-15
Abstract: A system and method of calibrating pressure transducers in an electro-pneumatic brake system for a railroad train in which a locomotive microprocessor generates a respective best fit curve for the train brake pipe, supply reservoir and brake cylinder pressures that approximates the actual train pressure therefore.   These best fit curves are generated from the pressure transducer readings of these pressures at each car by employing an equation based on a fourth order polynomial.      Each car is then provided with a theoretical reference pressure  signal  from the best  fit curve  for each of  the mentioned brake pipe, supply reservoir and brake cylinder pressures, according to the position of the car in the train.          The theoretical reference signal is then compared at each car with the car pressure transducer reading for the respective brake pipe, supply reservoir and brake cylinder pressures to obtain  a  transducer  error  correction  factor  that  remains constant  through  a  full  range  of  pressures.    The  error correction factor can be further calculated on the basis of a linear equation to obtain a variable error correction factor.

Patent CA-2166581-A1 (CA)
Inventor: PINAULT FRANCIS
IPC: H04B7/26
Filed: 1996-01-04
Abstract: The method involves storing a first list of base station frequencies within the mobile station's geographical zone periodically in the memory (20) of a subscriber identity module card (2). During connection, the mobile station measures a first reception level for each frequency defined within the network. A second list of frequencies is stored with second reception levels corresponding to the maximum power received by the mobile station. The two levels of reception for each frequency in this list are compared. If the comparison shows substantial equality, the mobile station is synchronised to the frequency in the first list which has the highest first reception level. Otherwise the synchronisation proceeds in order of decreasing first levels.
