Title: Method of preparing a phosphine compound
Inventor: MICKLETHWAITE COLLEEN E
IPC: C07F9/50
Filed: 1991-10-30
Abstract: ABSTRACT OF THE DISCLOSURE         Allylphosphines and vinylphosphines are prepared by reaction of a phosphine with an allylhalide or a vinylhalide, respectively.  Preferably the phosphine is a secondary phosphine, so that there is formed an allyldialkylphosphine or a dialkyl-vinylphosphine.  The allyldialkylphosphine can be reacted further with dialkylphosphine under free radical conditions to yield a 1,3-bis-(dialkylphosphino)propane. The dialkylvinylphosphine can be reacted further with dialkylphosphine under free radical condi-tions to yield a 1,2-bis-(dialkylphosphino)ethane.  These com-pounds are useful as bidentate ligands.

Title: Vapor storage canister with volume change compensator
Inventor: TURNER KENNETH W
IPC: F02M25/08
Filed: 1991-12-04
Abstract: A bed of activated carbon granules is maintained tightly packed within a fuel vapor storage canister housing by a specially designed compensator. A pair of spring loaded, nested trays move axially relative to one another and push continually into the lower face of the carbon bed to keep it packed. The trays also define a continuous, self maintaining gap that is smaller than the expected carbon granule size, preventing them from falling out in spite of the swelling of the canister housing.

IPC: G08G1/01
Filed: 1992-05-26
Abstract: VEHICLE DETECTOR WITH POWER    MAIN NOISE COMPENSATION                     ABSTRACT OF THE DISCLOSURE            A vehicle detector includes an inductive sensor which is driven by an oscillator to produce an oscillator signal having a frequency which is a function of inductance of the inductive sensor.   The presence of a vehicle is detected when the measured frequency of the oscillator signal changes by more than a threshold value.   The effects of magnetic flux produced by adjacent power lines are compensated for by means for measuring the frequency of the oscillator signal  during  a  plurality  of  sample  periods  and  for characterizing fluctuations of the measured frequency as a function of phase of a power main signal.  During a normal measurement period, the frequency of the oscillator signal is measured, and the phase of the power main signal during the measurement period  is determined.   An  output  signal  is produced by means based upon the measured frequency, the phase, and the known fluctuation of measured frequency as a function of phase of the power main signal.

Patent CA-2075889-A1 (CA)
Inventor: TAUT ULRICH
IPC: F24S20/20
Filed: 1992-08-12
Abstract: ABSTRACT            A regenerator, for example, in a hot-blast stove or a heat accumulator in a solar system, with an accumulator core (1) that is built up from ceramic or metal or natural material and which is used to accumulate "sensible" heat.  The accumulator core (1) is acted upon by a hot charging flow on one, "hot" side so as to become charged, until such time as on the other, "cold" side, a maximally permissible charging flow outlet temperature is reached.  In order to be discharged, the accumulator core (1) is acted upon from the other, "cold" side by a cold discharge flow until such time as a minimally permissible discharge outlet temperature is reached on the "hot" side.  In order to increase the heat absorption capacity for (sensible) heat without increasing the volume, on the hot side and/or the cold side of the accumulator core (1) there is a layer (3, 4) that serves as a temperature buffer and which delays achievement of the maximally permissible outlet temperature super-proportionally, or else increases the heat absorption capacity super-proportionally.

Title: Process for manufacturing galvannealed steel sheets having excellent press-formability and anti-powdering property
Inventor: SAGIYAMA MASARU
IPC: C23C2/28
Filed: 1991-12-27
Abstract: It is an object to provide a process for manufacturing galvannealed steel sheets having high anti-powdering property as required when they are press formed, and stabilized frictional properties in a coil. Steel sheets are plated in a bath having a low aluminum content, while they have, when entering the bath, a low temperature as defined in relation to the aluminum content of the bath, so that an alloying reaction may be prevented. Then, the sheets are heated for alloying in a high-frequency induction heating furnace so that the sheets leaving the furnace may have a temperature of from over 495°C to 520°C to yield galvannealed steel sheets consisting mainly of a ~1 phase. An iron or iron-alloy top coating having an appropriate iron content can be applied onto the plated steel surface to improve its paintability.

Title: Self-plugging blind rivet
Inventor: BROWNE LAURENCE ANTHONY
IPC: F16B19/10
Filed: 1992-10-07
Abstract: A self-plugging blind rivet 10 comprises a tubular body 14 having a preformed head 34 at one end, and in the bore 36 of which a headed stem 12 is disposed. The stem 12 projects from the head 34 end of the body 14, and the head 18 of the stem 12 is substantially enclosed by a region 42 of the body 14 remote from the preformed head 34. The head 18 of the stem 12 abuts a shoulder 44 provided by a region 43 of the body 14 in which the diameter of the bare 36 is reduced and the wall is thickened. Axially spaced apart annular grooves 46, 48 in the external surface of the body 14 define between them a portion 50 which will collapse to form a blind head when the body 14 is compressed axially by pulling the stem 12 while supporting the preformed head 34.      Finally, the stem head 18 may be pulled into the reduced diameter region 40 of the bore 36 and thereby cause the blind head to be reshaped and forced into compressive engagement with work being fastened. The stem head 18 remains securely enclosed by the body 14, whereby its loss is prevented.

Title: Quasi-resonant diode drive current source
Inventor: ORTIZ JOE A
IPC: H05B44/00
Filed: 1993-04-14
Abstract: A quasi-resonant diode drive current source provides high power pulsed current that drives light emitting diodes, and the like. The pulsed output current of the quasi-resonant diode drive current source is sensed, and is regulated by a control loop to a level required by the light emitting diodes. In a specific embodiment of the invention, a zero-current-switched full wave quasi-resonant buck converter is described that provides a high amplitude pulsed output current required to drive light emitting pump diodes used in a solid state diode pumped laser. The use of a quasi-resonant converter as a pulsed current source provides a much higher conversion efficiency than conventional laser current sources. This higher efficiency results in less input power drawn from a power source and cooler operation, resulting in a higher reliability current source.
