IPC: C08L75/04
Filed: 1990-11-26
Abstract: Abstract of the Disclosure HIGH MODULUS RUBBER COMPOSITION      It is desirable to increase the modulus of rubbers utilized in a wide variety of applications.  This invention discloses a technique for preparing high modulus rubber compositions.  By utilizing this technique, high modulus can be attained without sacrificing other properties, such as hysteresis.  The subject invention more specifically relates to a process for preparing a high modulus rubber composition which comprises:  (1) polymerizing at least one diisocyanate with at least one member selected from the group consisting of diols and diamines in a polymer cement of a rubbery elastomer under conditions which result in the formation of a rubber cement having the crystalline polymer dispersed therein; and (2) recovering the high modulus rubber composition from the rubber cement.

Abstract: A modem is connected to a terminal equipment and couples to another modem via a transmission line.  The modem includes a data transmission and reception part for making data transmission and reception with the terminal equipment, and a modem part for determining a modulation technique, for modulating a transmission signal from the other modem.  In addition, the modem includes a data compression and decompression part for determining a compression technique. The compression technique is used for compressing serial data from the data transmission and reception part before supplying the same to the modem part and for decompressing the compressed serial data from the modem part before supplying the same to the data transmission and reception part.  The modem further includes a speed determining part, notified of a communication speed between the modem and the other modem determined from the modulation technique and a compression rate of the data compression technique for determining an optimum communication speed when the connection between the two modems is established.  In addition, the modulation technique is determined and the data compression technique is determined, in response to outputs of the modem part and data compression and decompression part.  The speed determining part notifies the data transmission and reception part of the optimum communication speed, and the data transmission and reception part makes data transmission and reception with the terminal equipment using the optimum communication speed.

IPC: B60D1/04

Abstract: A trailer coupling which receives the annular eye of a drawbar over a rearwardly and upwardly-projecting pintle, has a latch which engages the pintle and overlies the drawbar to prevent the drawbar from becoming dislodged during use.  The latch is rotatable forwardly toward the body of the hitch, which is attached to the towing vehicle, to uncover the drawbar and permit its installation onto and removal from the pintle.  A pawl mounted on the body of the coupling engages a tang on the latch when the latch is in its latched position to prevent rotation of the latch to its unlatched position. Thus the latch cannot inadvertently open during use.  The pawl can be rotated away from the latch when it is desired to install or remove the drawbar.

Abstract: In order to reduce the concentration of propellant gases in the combat compartment, behind a weapon barrel, a smoke extractor (8) is arranged in the middle area of the barrel (7).          This smoke extractor (8) is connected to the barrel (7) so as to be gas-tight to the outside and is connected to the inside to the bore (5) of the weapon through an oblique blow-off passage (3) and through Y-shaped valve passage (2).  The valve passages (2) are closed by a non-return valve (6) in the form of a spring packet made up of stratified leaf springs.  This ensures that the smoke extractor is filled with propellant gases and also ensures very rapid closure of the non-return valve, which is decisive for achieving the desired long blow-off time for the gases through the blow off passage (3).

Inventor: SCHEUER MARK A
IPC: G01N21/47
Filed: 1992-08-25
Abstract: In a single pass tri-level imaging apparatus, a pair of Electrostatic Voltmeters (ESV) are utilized to monitor various control patch voltages to allow for feedback control of Infra-Red Densitometer (IRD) readings.      The ESV readings are used to adjust the IRD readings of each toner patch. For the black toner patch, readings of an ESV positioned between two developer housing structures are used to monitor the patch voltage. If the voltage is above target (high development field) the IRD reading is increased by an amount proportional to the voltage error. For the color toner patch, readings using an ESV positioned upstream of the developer housing structures and the dark decay projection to the color housing are used to make a similar correction to the color toner patch IRD readings (but opposite in sign because) for color, a lower voltage results in a higher development field).
