Patent CA-2109494-A1 (CA)
Inventor: FERNANDEZ RICKEY J
IPC: F16H59/02
Filed: 1993-10-28
Abstract: There is provided a mechanism for engaging a power takeoff employed primarily to drive a load from a truck engine; the mechanism having a solenoid with a high energy coil that is energized for a short interval to produce engagement of the power takeoff and a low energy coil to maintain engagement of the power takeoff.  The mechanism includes an armature movable from a retracted to an activated position to move the power takeoff engagement mechanism to a power takeoff engaged position and a high rate spring which is compressed if the power takeoff does not engage whereby to return the armature to its retracted position upon de-energization of the high energy coil.  A second lower rate spring moves the armature to its retracted position upon de-energization of the lower energy coil.
Patent CA-2110057-A1 (CA)
Inventor: SACKHEIM ROBERT L
IPC: B64G1/24
Filed: 1992-08-07
Abstract: In the preferred embodiment of the invention, a cooled bipropellant thruster (70) for controlling the on-orbit position and orientation of a spacecraft is provided. The cooled bipropellant thruster (70) uses a liquid fuel and liquid oxidizer. The liquid fuel is decomposed in a first chamber (72) with a catalytic bed of decomposition material (74) and produces at least one reaction gas, which flows to the second reaction chamber (90). The second reaction chamber (90) is heated by the reaction gas, but is cooled by liquid oxidizer flowing through cooling passages (92, 94, 98, and 102), which brings the oxidizer into a heat exchange relationship with the second reaction chamber (90). During the heat exchange relationship, heat is transferred from the second reaction chamber (90) to the oxidizer and the oxidizer transforms into a gas. The gaseous oxidizer is fed into a second reaction chamber (90) to secondarily react with the reaction gas.

Title: Black compensation circuit for a video display system
Inventor: WHITE CHARLES M
IPC: H04N5/16
Filed: 1994-02-03
Abstract: A driver for a cathode ray tube includes a black level compensation circuit which generates an offset voltage which tracks the current flowing to the output of the driver and therefore the average picture level (APL). The offset voltage is added as a component of the output voltage so as to increasingly shift the output voltage toward black as the APL increases. This compensates for CRT gamma non-linearities and for light scattering effects which might otherwise cause the loss of perceived detail and sharpness in dark areas of a high APL image.      In the disclosed embodiment, the driver comprises a cascode amplifier and the offset voltage generating element includes a capacitively bypassed resistor connected in a reference voltage network connected to the emitter circuit of the lower (common emitter configured) transistor of the cacode amplilfier.
Patent CA-2115682-A1 (CA)
Inventor: KONO IKUO
IPC: E21B7/00
Filed: 1994-02-15
Abstract: An   apparatus    for   constructing   subterranean structures, soil-chemicals mixture or soil-agents mixture by using a multi-shaft auger machine to mix oil with a chemical hardener in situ.   As the auger shafts of the multi-shaft  auger  machine  penetrate  the  soil, spiral flights attached to the auger shaft above the initial auger  blades  assist  soil  in  passing  by  supporting structures located between adjacent auger shafts. The spiral flights both assist in raising the soil beyond the supporting structures and also prevent reagglomeration of the soil prior to passing by the supporting structures.          The spiral flights have a diameter less than that of the auger  blades  attached  to  the  shaft  below  the  spiral flights and have a connection ranging from 360 degrees to 720 degrees around the shaft.   The use of the spiral flights within this location results in a reduction in the amount  of energy needed  to auger a borehole,  thereby resulting in excess energy for a more homogeneous mixing of the chemical hardener in the soil through which the auger passes. In addition to the increase in efficiency because of the available energy, the spiral flights also directly increase the surface area of structures attached to  the  auger  shaft  thereby  increasing  the  mixing efficiency of the auger shaft as it passes through the borehole.  The increased efficiency and the prevention of reagglomeration  of soil are most beneficially observed in clay or clay-like soils.

Inventor: SMITH KEVIN
IPC: H04B10/291
Filed: 1993-04-26
Abstract: A system for recovering a clock from an optically encoded signal uses a mode-locked laser (4). A modulator (2) is connected in common with the laser cavity (3) of the laser ana won a transmission path (1) which applies the input optically encoded signal to the modulator (2). The modulator (2) in response to the optically encoded signal modulates the phase-and/or amplitude of light in the laser cavity (3) thereby locking the phase and frequency of an output pulse stream to the timing wave of the optically encoded signal. In a preferred example, the modulator is a non-linear optical modulator used for cross-phase modulation (XPM) of the light in the laser cavity.

Title: Process for patenting and brass plating steel wire
Inventor: BHAGWAT ANAND W
IPC: C23C2/38
Filed: 1994-11-03
Abstract: It is usually desirable to utilize brass coated steel wires in the reinforcement of rubber articles, such as tires.  To impart such wires with the ability to be drawn to obtain desired high tensile strengths and toughness they are normally patented.  Patenting and brass plating are conventionally done as separate steps.  This invention relates to a process for simultaneously patenting and brass plating a steel wire which comprises:     (a)  continuously passing the steel wire through a molten mixture of copper and zinc to apply a brass coating thereto, wherein the molten mixture is maintained at a temperature which is within the range of about 930°C to about 1100°C, and wherein the steel wire has a residence time in the molten mixture which is within the range of about 6 seconds to about 15 seconds which is sufficient for the steel to be austenitized;     (b)  continuously wiping excess brass from the austenitized steel wire as it exits the molten mixture to attain a brass coated steel wire having a brass coating weight which is within the range of 2 to 8 grams of brass per kilogram of the steel wire;     (c)  cooling the brass coated austenitized steel wire to a quenching temperature which is within the range of about 500°C to 650°C until a transformation from austenite to pearlite takes place;    (d)  further cooling the patented brass plated steel wire to ambient temperature.
