Patent CA-2010642-A1 (CA)
IPC: B60T8/70
Filed: 1990-02-22
Abstract: ADAPTIVE WHEEL SLIP THRESHOLD            Abstract of the Disclosure A brake control system is described that maximizes vehicle braking efficiency by first determining, and then cycling wheel brake pressure and consequently wheel slip about, the critical slip value for the road surface.  As each road surface has unique tractive characteristics, the amount of brake pressure required to produce critical wheel slip, and hence maximum  brake force, varies for different coefficient of friction road surfaces.  This invention determines the coefficient of friction for the operating surface and adjusts the system slip threshold to accurately mimic the actual critical slip value for the road surface.  The invention then applies and releases wheel brake pressure so as to cycle wheel slip about this critical slip value.

IPC: E06C7/00
Filed: 1990-02-27
Abstract: IMPROVED SUPPORT BRACKET Abstract of the Disclosure A work support bracket is improved by providing it with brace members having a ? cross sectional shape.   The brace members are fixed to first and second horizontal socket members respectively such that the upper horizontal segments of the brace members extend away from one another.  The lower, central regions of the vertical segments of the brace members are notched to straddle the first and second horizontal socket members respect-ively.   The outward, central regions of the upper horizontal segments are notched to define elongated pathways extending through  first and second generally vertical  socket members respectively and through said notched outward central regions respectively.  The lower horizontal segments of the brace members are first and second pairs of tab members which extend from opposed ends of the first and second brace members respectively. The first pair of tab members is coplanar with the upper surface of the first horizontal socket; and, the second pair of tab members assumes a position coplanar with the first horizontal socket,  when  the  first  and  second  horizontal  sockets  are interconnected.  The lower horizontal segment of the second brace member has a third tab member which extends atop the second horizontal socket member, coplanar with the first horizontal socket, when the first and second horizontal socket members are interconnected.

Title: Fiber optic gyro
IPC: G01C19/72
Filed: 1990-03-22
Abstract: ABSTRACT OF THE DISCLOSURE      A   modulated   phase   difference   is   detected between  two  rays  of light  phase  modulated  by  a  phase modulator, having propagated through an optical fiber coil in opposite directions and interfering with each other. A ramp  voltage  controlled  in  polarity  and  frequency  in accordance   with   the  detected   phase   difference   is generated.    The  ramp  voltage  is  applied  to  the  phase modulator to control it so that a maximum phase shift of light thereby is 2.pi. k rad (where k =  ? 1,  ? 2, ...).  To correct  the  temperature  characteristic  of  the  phase modulator,   a  peak  value  control  circuit  creates  a reference  voltage  corrected by a  voltage detected  by  a temperature  sensor  and  controls  the  peak  value  of  the ramp voltage by  the  reference voltage,  thereby ensuring that  the  maximum  phase  shift  of  light  in  the  phase modulator  is always   2.pi. k rad regardless of temperature changes.

Abstract: A steel rib (100), designed for affixation to the interior of an underground storage tank (116), provides improved compression characteristics, with a reduction in cost of preparation and materials. The rib (100) is provided with diametrically opposed vents (102,104), which may be formed by cutting a portion of a hollow, rectangular rib (100), rotating it 90 DEG  in a direction orthogonal to the plane of the rib (100), and reaffixing it, so as to occlude the interior of the rib (100). When used to reinforce a double-walled tank (116), the rib (100) allows the strengthening of the outer wall (112) to enhance resistance to penetration and damage frequently incurred in handling, and reduce installation costs.

Abstract: A  CMOS  integrated  circuit  for  driving  capacitance devices is provided.  The circuit has an input node and an output node  and  includes  a first  transistor  operatively connected to the input node which is turned "on" and "off" by the input node to supply an output signal to the output node when turned "on".  A second transistor is provided, the output of which is connected to the output node when turned "on" to supply an output signal thereto.  A control circuit is provided to turn on the first transistor prior to the second transistor, and to turn on the second transistor if and only if the slew rate of the output signal of the first transistor is less or slower than a given value.  With this arrangement,  if there  is a low total capacitance of the capacitance devices being driven, the first transistor will have a fast enough slew rate that it will perform the entire charging function of the devices without turning on the second transistor; however, if the total capacitance of the devices being charged is sufficiently large,  the low slew rate of the first transistor will cause the second transis-tor to be turned on, thereby providing additional charging voltage to the capacitance devices, thus decreasing the time that would be required if only the first transistor were employed for the entire charging.

During inflation molding, the resin composition is extruded at an extrusion temperature T(°C) which satisfies the equation:         240°C ? T(°C) ? (MP - 26) + (53 x IVa) where MP is the melting point of the resin composition as determined by differential thermal analysis at a rate of 10°C per minute.  The films will exhibit a low haze value of less than 10% as determined by ASTM D 1003.

Title: Process for converting carbon disulfide to hydrogen sulfide in hydrogen sulfide/carbon disulfide mixtures
Inventor: SCHATZ GEORGE R
IPC: C01B17/16
Filed: 1991-01-28
Abstract: A process for converting carbon disulfide (CS2) to hydrogen sulfide (H2S) in mixtures of H2S and CS2 is provided. The H2S/CS2 mixture is combined with water to form a hydrolysis feed mixture. The hydrolysis feed mixture is passed through a hydrolysis reactor containing e.g., an alumina-based catalyst, wherein a substantial portion of the CS2 is converted to additional H2S. A vapor product comprising H2S, CO2, unreacted H2O, unconverted CS2 and sulfur is formed by the hydrolysis reaction. The vapor product is cooled to form a H2S/CO2 vapor phase and a sour water condensate phase. The H2S/CO2 vapor phase is separated from the sour water condensate phase and subsequently recovered. The sour water condensate phase, which contains small amounts of solid sulfur particles, is optionally then combined with additional CS2 and decanted to form a sulfur-free sour water layer and a CS2 layer containing dissolved sulfur. The sour water layer is recycled and combined with the original H2S/CS2 mixture. The CS2 layer is recycled to a sulfur removal device to remove the sulfur dissolved in the CS2.
