Title: Telephone network data transmission
Inventor: JONES BARRY W
IPC: H03K9/08
Filed: 1991-04-30
Abstract: Telecommunication switching interface system and method wherein transmissions of synchronous digital data from a master control unit (50A) (Figure 9) to a slave, network termination unit (50B) are via a pulse width modulated data stream including pulse width modulated binary code pulses (20, 22) (Figure 2) with a pulse width modulated phase synchronization pulse (24) all of which have a preselected leading edge transition (28) at the same point in each cycle of a master clock signal. A clock signal is derived at the network termination unit (50B) from the received pulse width modulated binary data stream for decoding and for nonself-clocking, synchronous transmissions from the slave, network termination unit (50B) to the master, control unit (50A). The phase synchronization pulse (24) is employed to maintain phase synchronization between the transmission to and from the control unit (50A). <IMAGE>

Title: Tapered plug valve
Inventor: HOLLINGWORTH KEITH JEFFREY
IPC: F16K5/22
Filed: 1991-05-30
Abstract: A tapered plug valve has a sealant reservoir 30 associated with the valve body and control means 31 operable in the event that the plug becomes wedged to cause pressure to be applied to the sealant in the reservoir. Sealant then flows through a passage 59 to grooves 5, 8 formed in the interior seating surface for the plug, causing the plug to become unwedged. The plug may be formed with one or more grooves which are so positioned that on rotation of the plug the grooves or each groove does not communicate with fluid flowing through the valve. <IMAGE>

Patent GB-2262579-A (GB)
Title: Vehicle brake system with anti-skid device
Inventor: MAISCH WOLFGANG
IPC: B60T8/26
Filed: 1992-12-16
Abstract: On brake application in the event of failure of the anti-skid device of a motor vehicle hydraulic brake system, a solenoid valve 39 of a pressure-control device 9 is not energised and acts as a one-way valve opening only when master cylinder pressure exceeds a pre-set value (p sigma , Figs 3 & 4) so that the brake pressure in the rear wheel brake cylinders is reduced relative to the brake pressure in the front wheel brake cylinders in order to prevent locking of the rear wheels before locking of the front wheels of the vehicle. On brake application, when the anti-skid device is operational, the solenoid valve 39 is energised but only assumes a fully open condition when the master cylinder pressure exceeds a switching pressure (ps). The magnetic force acting on the armature of the valve is sufficient to retain the valve in its fully open position until the master cylinder pressure reduces to zero. In this manner, the switching frequency of, and thus the wear on, the pressure-control device (9) are greatly reduced. The solenoid (70) is designed, or is energized, in such a way that it is heated to a lesser extent when it is energized. With anti-skid device failure, brake fluid can return, on brake pedal release, via one-way valve 40. <IMAGE>

IPC: B22F5/00
Filed: 1997-07-22
Abstract: A Fe based sintered alloy synchronizer ring comprises an inner circumferential surface 101 which, in order to enhance its frictional characteristics, scuffing resistance and stable quality, is subjected to an aqueous vapour treatment, eg at 550{C for 30 minutes, to form a layer of iron oxide film having a major component of Fe 3 O 4 . The film has a surface roughness of between 20~mRz to 50~mRz and a thickness of between 0.05~m to 5~m. In addition to the vapour treatment the internal surface may be blast treated which further improves the rings frictional characteristics, scuffing resistance etc. The sintered body is produced by mixing graphite powder, Cu powder and Fe powder and then pressing the mixture at a pressure around 4.5 to 6.5 t/cm 2 to yield a green compact which is sintered at a temperature of around 1000 to 1200{C to form the body.
