Patent GB-2073980-A (GB)
Title: Speed signal determination
IPC: G01P3/489
Filed: 1981-04-01
Abstract: A signal indicative of speed of displacement, for example in respect of steam turbines, has to be repeatedly obtained for control purposes typically in periods of 0.01 sec. with good resolution over substantially the whole speed range. Speed is derived from a count of time pulses generated in a period and a count of displacement pulses (derived from two relatively movable parts) equal to a registered number to determine the duration of the period. The duration of the next successive period is achieved by determining whether the count of time pulses is within, below or above a range set by lower and upper limits and respectively maintaining, increasing or decreasing said registered number accordingly. An overspeed facility is provided. Acceleration is determined using successive speed measurements. Linear speeds and accelerations can also be determined. <IMAGE>

Title: Method of producing glass film using solution containing silicon alkoxide
IPC: C03C3/062
Filed: 1981-05-29
Abstract: A uniform and transparent film of silica glass is produced from a solution obtained by hydrolysis of a silicon alkoxide in a solution containing water, a hydrophilic organic solvent and an acid as a hydrolyzing catalyst. A film of the viscous solution is formed in a free space without using any liquid or solid surface to support the film by, for example, drawing through a slit or scooping with a ring. The film is allowed to gel in the atmosphere and finally heated to about 1000 DEG C. A film of modified silica glass containing in the glass matrix at least one metal, e.g. Ti or Zr, can be produced generally similarly by using a mixture of a silicon alkoxide and desired metal alkoxide(s) as the starting material.

Title: Battery charging system
IPC: H02J7/00
Filed: 1981-06-01
Abstract: A traction battery charging system comprises a battery pack (10), a rectifier (12), a current regulator (18), a voltage detector (20) and a controller (16) for automatically performing each charging cycle. Each charging cycle comprises a first phase in which the battery is charged at 30A until the battery voltage reaches a predetermined value, a second phase in which the battery is charged at 20A until the battery voltage reaches a second predetermined value, and a third phase in which the battery is given an overcharge at 10A for a period which depends on the time spent in the first phase. The time spent in the first phase is indicative of the state of discharge at the commencement of charging and thus the value of the overcharge is determined in accordance with the state of discharge. At a predetermined time after the end of the third phase, the battery is given an equalising charge. <IMAGE>

Title: Temperature measuring system
IPC: G01K7/18
Filed: 1981-06-04
Abstract: A temperature measuring system comprises a sensor 14 which is connected to a supply rail 10 through a first lead 12, and which may be selectively connected by a relay 24 through a second lead 16 or a third lead 20 to the inverting input of an operational amplifier A1. The leads 16 and 20 have different resistance values. The output of the amplifier A1 is connected to its input through a resistor R1, and its non-inverting input is connected to the rail 10 through a potential divider R3, R4. The output of the amplifier A1 is connected to a computer 30 through a low pass filter 26 and an A/D converter 28. In operation, the output voltage of the amplifier is first measured with the lead 16 connected to its inverting input and then measured again with the lead 20 connected. From these measurements the resistance of the sensor is calculated after calculating and hence eliminating the resistance of the leads. The sensed temperature can then be calculated from the resistance of the sensor. <IMAGE>

Patent GB-2098285-A (GB)
Title: Wrap spring clutch
IPC: F16D67/06
Filed: 1981-11-17
Abstract: For clutch engagement, an actuating current is supplied to coaxial solenoid 18 so that non rotating slotted actuator plate 12 is drawn towards solenoid 18 against the action of leaf spring 20. Control tang 23 of spring 13 is then free to rotate and due to frictional forces wraps down onto rotating input shaft 10. For disengagement, the current is switched off and leaf spring 20 urges plate 12 away from solenoid 18 resulting in engagement of control tang 23 with one of slots in plate 12. Solenoid 18 may be replaced by a hydraulic ram and the spacing of slots in plate 12 may be varied to determine the extent of rotation of shaft 11 with each engagement. <IMAGE>

Title: Centre ring hydrogenation and hydrocracking of poly-nuclear aromatic compounds
Inventor: HUIBERS DEREK THEODOR ADRIAAN
IPC: C10G45/44
Filed: 1982-07-14
Abstract: Polynuclear aromatic compounds obtained from petroleum residua and coal liquids and containing three to six aromatic ring compounds are first catalytically hydrogenated and then hydrocracked, either thermally or catalytically, to produce high yields of two-ring and mononuclear aromatic products. Useful hydrogenation reaction conditions are 149-482 DEG C (300-900 DEG F) temperature, and 69-124 bar gauge (1000-1800 psig) hydrogen partial pressure. The hydrogenation catalyst used can be nickel-tungsten on a silica-alumina support. The hydrogenated material is then hydrocracked at conditions of 427-704 DEG C (800-1300 DEG F) temperature, and 34-207 bar gauge (500-3000 psig) hydrogen partial pressure. The hydrocracking step may use a catalyst comprising cobalt- molybdenum on alumina and a space velocity of 3-7 gm/hr/gm catalyst. A preferred feedstock is steam-cracker pyrolysis tar such as produced from steam cracking of ethylene.

Patent GB-2126844-A (GB)
Title: Multipath correction in radio systems
Inventor: MUNDAY PETER
IPC: H04B1/713
Filed: 1982-09-11
Abstract: A digital radio system has means to compensate for dominant path changes during transmission. The input data stream is divided into notional frames and synchronisation signals are inserted between the frames in the transmitter. At the receiver each frame of the input data stream is read into a FIFO store (30) and read out therefrom after a time delay T0-t1 where T0 is a constant and t1 is a transmission delay of the signal over its transmission path. If the dominant path changes during transmission, the corresponding change in t1 will be sensed by detecting the next synchronisation signal after the path change. This variable time delay in reading out data from the FIFO store 30 compensates for the jump in the data stream that would normally be caused by the path change. <IMAGE>

Title: Motor vehicle control arrangement
Inventor: ANDREI-ALEXANDRU MARCEL
IPC: B60T13/74
Filed: 1983-03-09
Abstract: In a control arrangement for a motor vehicle including a brake system and an engine, which can be arbitrarily switched off by the driver via a switching device, for example by a so-called stop-start device 40, the brake is arranged to be automatically applied when the vehicle speed is below a set value, or negative, upon switching-off of the vehicle engine (by switch 42). This saves an application of the handbrake at every stop such as at a traffic light which has been necessary until now. In the circuit shown, a switching signal for switching off the engine is tapped off at the output 36 of the "stop-start device" 40 and conducted to a switching stage 34 which produces the adjusting signal for the adjusting element in the form of an electric motor 15 acting on the parking brake linkage. Alternatively the adjusting element acts to retain foot brake pressure. <IMAGE>
