Abstract: o A brake control system for a multiple unit train of mixed motor cars and trailer cars - of the type usually to be found operating as metro or mass transit trains - and in which the motor cars have dynamic brakes operation of which is blended with, but given preference over, the friction brakes of all units. A brake demand signal calling for a given level of train retardation is weighted on each vehicle, according to the load of the vehicle, and the level of dynamic braking effort invoked on each motor car is limited in accordance with a maximum adhesion level calculated in proportion to the measured load of that car. In a modified arrangement the adhesion level is calculated in accordance with the load of the lightest loaded motor car. Signals representing the amount of dynamic brake effort achieved by each motor car is supplied to a trailer car and subtracted from the load weighted braking effort for the trailer car and the result used to actuate the friction brakes of the trailer.

Abstract: A coin routing gate comprising a pivotally mounted gate member (50) which has a first position from which it can be deflected by a moving coin (102) to a second position to permit the coin to take one path (R), and electrically energisable retaining means (60) which is selectively operable to retain the gate member in its first position to cause the coin to take another path (A), characterised in that the gate member when in its first position provides part of a coin track (37,50) on which coins travel on edge, the gate member is deflectable from the first position to the second position by the weight of a coin, and the gate member when retained by the retaining means in its first position is not deflected by the weight of a coin so that the coin continues to travel on the coin track. No power is required to route the coin to said one path, because this is done solely in response to the weight of the coin. The power required to route the coin to the other path is only that required to retain the gate member in its first position and this can be made extremely low. Thus, the power consumption of the gate can be made very low so as to suit it for low power applications such as coin operated telephones.

Abstract: This invention relates to fiber optic frequency shifters for producing optical signals of a desired frequency range for input to a device such as an optical rotation sensing system. The rotating birefringence is created in a length of fiber optic material, which has the effect of a rotating half-wave plate upon an input optical signal. The length of fiber optic material may have a jacket of either an electrostrictive or a magnetostrictive material formed thereon such that application of an appropriate field to the jacket compresses the enclosed fiber to induce birefringence therein by means of the photoelastic effect. A half-coupler having a block of electro-optically active birefringent material adjacent the interaction region combined with an electrode configuration and circuitry for producing a rotating electric field in the block also produces a rotating half-wave plate frequency shifter. The evanescent field of light propogating in the optical fiber interacts with the rotating birefringence and experiences a frequency shift. The invention also includes feedback circuitry for processing the optical output of fiber optic rotating half- wave plates to maintain the intensity of components in the output signal having the carrier frequency below a threshold value.

Abstract: Error detecting and correction operations for a plurality of input bits comprised of input data bits (ID0-ID39) and associated check bits (CB0-CB7) are implemented using two IC chips in order to overcome chip output limitations. In addition, redundancies derived from the use of two IC chips are employed to provide automatic self-checking of the detecting operation of each chip. The use of two identical IC chips (10 and 10') for this purpose is made possible by employing a specifically chosen inversely symmetrical Hamming code and by wiring the input data bits and the input check bits in an inverse manner with respect to the input terminals of the two IC chips. As a result, even though each IC chip performs the same error detecting and correcting operations, it does so inversely with respect to the input data bits and the input check bits so that each IC chip is able to provide one-half of the required output bits.

Abstract: Apparatus for stacking conical objects (2a, 2b, 2c, 2d, 2e) includes right hand and left hand side walls (3) and (4) which are joined by divergent walls (7) to define a tapering horizontal cross-section column (l) in which the spacing between the opposite walls (3) and (4) is shorter than the length of any one of the conical objects (2a-2e). The conical objects can be placed manually in the top of the column (l) but only in a given orientation (thanks to the tapering horizontal cross-section of the column (l) and only when hooked on a retaining finger (5) projecting into the column through the side wall (4). The conical object (2e) at the top of the stack thus settles into an inclined orientation which it retains when the retaining means (5) is released to drop the cone (2e) down the column, thanks to an inertia brake (8) to retard the wider diameter end of the falling cone and preventing the cone from becoming vertical. Retaining means (l0) at the foot of the column releases only the bottom cone (2a) and allows any cones above it to become indexed downwardly into the bottom-most position.

Abstract: The device has a hub body (4) which is screwed into the end face of the knife shaft (1) and on which there is seated an annular piston (8) which acts axially on the knives (20). A piston (6) is screwed into the hub body (4). A drive part (31) having an external hexagon (32) designed to take a spanner is connected via a torque-limiting system (41) to the piston (6). During assembly, the hub body (4) is screwed in until the annular piston (8) rests on the knives (20). When the drive part (31) rotates, the piston (6) displaces oil into the cylinder chamber (10) of the annular piston (8) so that the knives (20) are securely clamped. If a predetermined torque is exceeded, the drive part (31) continues to rotate with respect to the piston (6) by means of a torque-limiting system (41). The optimum contact-pressure force of the annular piston (8) can consequently be precisely adhered to during assembly. <IMAGE>

Date Dec. 15, 1988.A continuously variable differential (10) uses a continuously variable transmission (50) that is rotated by drive torque and controlled to vary the speed ratio between its outputs. These, which previously transmitted power through the transmission, are connected with a pair of drive shafts such as opposed drive axles (17 and 18) that rotate with the transmission under drive power. Differentiation between the shafts transmits through the transmission via variable speed ratios that control the moment arms, mechanical advantages, and torque bias ratios. This arrangement allows the torque to be distributed according to sensed vehicle conditions. It can apply more torque to a wheel retaining traction when its opposite wheel slips, and it can apply a larger portion of the torque to wheels bearing more weight or to a faster rotating wheel on an outside of a curve.

Abstract: A machine for reprocessing catheters of the type having a double lumen, one of which leads to a balloon. A used catheter is sealed within a cassette which in turn is connected by multiple ports to a cleaning side of the machine. Cleaning solution is flushed through the inside and outside of the catheter. The balloon integrity is tested by adding step wise volume additions and monitoring the pressure. The data generated is compared to a standard curve for new catheters. The cleaned, sterile catheter is then rinsed to remove all traces of sterilant. Sterile saline is alternatively flushed through the cassette and catheter. The balloon is again tested for leaks. No portion of the rinse side of the machine requires sterilizing except for the disposable tubing set and saline source. The rinsed, clean and sterile catheter is removed from the cassette for reuse.
