Title: Surface-modified micaceous particulates having improved dispersibility in aqueous media
Inventor: CARPENTER CLINT W
IPC: C09D5/02
Filed: 1991-05-09
Abstract: Abstract Compounds useful for improving the dispersibility of micaceous particulates in aqueous-based coating compositions comprise urethanes or ureas which are the reaction products of silylalkyl or silylaryl isocyanates with alcohols, amines, polyether alcohols or amine-terminated polyethers.  The compounds may also be the reaction products of silylalkyl- or silylarylamines with half-blocked diisocyanates which are themselves the reaction products of a diisocyanate with an alcohol, amine, polyether alcohol or amine-terminated polyether.     Micaceous particulates which have been surface modified by reaction with these compounds, as well as coating compositions comprising such surface-modified micaceous particulates, and coated substrates are also disclosed.
Patent CA-2042663-A1 (CA)
Title: Flush bolt boring jig
Inventor: TAYLOR RICHARD
IPC: B23B47/28
Filed: 1991-05-15
Abstract: ABSTRACT    A flush bolt boring jig is rigidly attached to a drill. The drill has a bit which is the length of the bore to be formed in the door. The jig holds the drill rigidly so the bore being drilled in the door is parallel to the free end of the door. This is done by tracks mounted by clamps in such a way that the tracks are parallel to the free end of the door. The jig is attached to a pair of slide tubes which slide on the tracks. Since the drill is attached to the jig, as the hole in the door deepens, the drill moving with the slide tubes over the tracks moves in a straight line so that the bore being formed is exactly parallel to the free end of the door.

Title: Multipad brake lining fabrication method, and lining so produced
IPC: B22F3/12
Filed: 1991-05-16
Abstract: The invention relates to a method of producing a brake lining (23) in which the blocks (25) sheathed by a less fragile bead (9, 90) are fixed to a metal support (12), the method being characterised by the following steps: 
 
  (a) one side of said support (12) is coated with a braze-welding suspension which is oxidised and then reduced, to give a bonding surface; 
  (b) a mixture of powdered friction products is shaped up, and borded, and divided into a number of portions (80) which will become said blocks (25), by beads of metal powders which will become said less-fragile beads (9, 90); 
  (c) said mixture of powders is compressed and applied to said bonding surface of the metal support (12); 
  (d) the resulting assembly is heat-treated under a reducing atmosphere to sinter and weld it; 
  (e) the resulting piece is forged at over 400 DEG C, thus reducing the height of its mixture of sintered powders by at least 15%; 
  (f) grooves are formed in said less-fragile beads (90), dividing said sintered mixture into separate sheathed blocks (25), leaving at least 0.5 mm of guard (26) off the support (12). 
 
<??>The invention also relates to the resulting brake lining (23). It is used for the brakes of railway and automobile vehicles, aeroplanes and helicopters, and industrial machines.

Title: Overcurrent trip circuit
Inventor: BEG MIRZA A
IPC: G01R19/165
Filed: 1991-08-13
Abstract: 56,150 ABSTRACT OF THE DISCLOSURE         An overcurrent trip circuit monitors the rate of rise of  the current and the magnitude of the current in a power conductor and opens  a circuit  containing the power conductor  when  either  the  rate  of rise of the current exceeds a first preselected  limit value  or the magnitude of the  current exceeds  a second preselected limit value.          The inherent inductance in a  metering  shunt  is  used to produce a  voltage signal  that contains a component which is representative of the  rate of  change of  current in a power  conductor.    This  voltage signal is compared to a first reference signal to produce a  trip signal  when the voltage exceeds  the first reference signal.  In addition, the voltage signal is processed and  the processed voltage signal is compared to a second reference signal to produce a second trip signal when the  magnitude of  the processed voltage signal  exceeds the magnitude of the second refer-ence signal.  The power circuit is then opened in response to either of the first or second trip signals.

IPC: G07D3/16
Filed: 1991-09-18
Abstract: The type of denomination of a coin inserted through a coin slot is discriminated by a coin discriminating section while the coin is being conveyed substantially horizontally by a mechanism for horizontally conveying coins, and the discriminated coin is distributed by coin distributing levers for selectively executing a first distributing operation for distributing coins to a relevant coin accumulating section and a second distributing operation for introducing the coins to an ensuing coin distributing section.  As for the coin distributing levers, all the coin distributing levers leading to the coin distributing section corresponding to the discriminated type of denomination are set in a state in which the first distributing operation is prohibited, and subsequently the coin distributing section corresponding to the discriminated type of denomination is caused to effect the first distributing operation, and as the coin to be distributed passes through the coin distributing levers, the state in which the first distributing operation of the coin distributing sections leading to the coin distributing section corresponding to the discriminated type of denomination is prohibited is sequentially canceled.

For this reason, the groups of suction pads have their supports resting on two split contrary thread spindles, in such a way that with a single manual control and connecting both spindles by chain transmission displacement thereof is obtained all along the guide bars, thus establishing the work position of said suction pads. The purpose of the lap lifting device is to auto-matically effect the lifting of the laps to the prede-termined angular position. For this reaon it comprises a strip, tiltable by the action of pneumatic cylinders, which through their action of a shaft, to which the arms of the strip are joined, push the laps to their predeter-mined position. It comprises a means of approximation or separation in accordance with the format or dimensions of the laps.
