Title: Diaphragm valve
Inventor: JONAS ROLF
IPC: F16K7/12
Filed: 1985-04-11
Abstract: A diaphragm valve for corrosive liquids comprising a thin diaphragm (4) in contact with the liquid, and a thicker backing diaphragm (5) of rubber or the like are attached to a compressor (7) by a stud bolt (13) which is secured in the compressor by a bayonet closure comprising a cross pin (14) in the top end of the stud bolt (13). During fitting of a new diaphragm the cross pin is inserted into the recess (15) through a slot (17) and rotated about an angle of 90 degrees. The backing diaphragm (5) is provided with a central aperture which facilitates exchanging the backing diaphragm only without having to withdraw the cross pin (14) out of the bolt (13), which is usually firmly retained therein by rust or dirt, by pushing the cross pin through the aperture. <IMAGE>

Title: Communications system
Inventor: DAVIDSON IAN ARTHUR
IPC: H04N7/10
Filed: 1985-07-19
Abstract: A communications system has a plurality of remote stations linked to a master station via three channels, two of which are data channels, and one of which is a signal channel. The two data channels carry time multiplexed digital signals to and from the master station respectively. The signal channel is used by all the remote stations for initiating communication with the master station, which in response to a remote station's signal allocates to that remote station a particular time slot. The system may be part of a satellite communications system, or it may be combined with a cable television distribution network.

Title: Slow scan television apparatus
Inventor: SIRA HARJINDER
IPC: H04N7/12
Filed: 1985-08-09
Abstract: Video information is stored in a 64K x 6 memory 9 as 256 lines with 256 pixels per line. The memory addresses for each pixel are scanned in sequence at a fast scan rate, with one address being accessed per fast scan cycle. During each cycle a second - slow - address is also accessed. A fast address counter 36 counts fast addresses and a slow address counter 34 counts slow addresses. An address multiplexer 35 feeds these addresses alternately to the memory 9. A read/write memory control 14 normally controls the memory to read out fast video information from the chosen fast address during the first half of each fast cycle and to read out slow video information from the chosen slow address during the second half of each fast cycle when in a transmit mode or to write in slow video information to the chosen slow address during the second half of each fast cycle when in the receive mode. <IMAGE>

Title: V.M.G. (velocity made good) comparator
Inventor: HIRST JOHN CHRISTOPHER
IPC: G06G1/08
Filed: 1988-07-11
Abstract: A VMG comparator, for use on a sailing boat, is made with three relatively movable discs, and has sliding logarithmic scales A & B which give values of VMG corresponding to boat-speed for a boat in a close-hauled condition after scale B has been displaced by aligning pointer D with values of tacking angle on the lower disc. In addition, comparison of VMG with a boat which has borne off a few degrees may be made by displacing a third logarithmic scale C by means of aligning the appropriate tacking angle pointer F, on the top disc, with values of angle borne off on the middle disc. Values of VMG for boats on any point of sail may be displayed by aligning pointer F on the upper disc with values of angle between actual and desired courses on a lower disc. In this case VMG will be read from either scales A or B corresponding to boat-speed on scale C. <IMAGE>

Title: Pipe fitting
Inventor: BATES JOHN RICHARD
IPC: F16L41/12
Filed: 1989-03-08
Abstract: At least two members 10, 20 each defining a substantially arcuate surface, are adapted to be connected together so as to encircle a pipe 30. The substantially arcuate surface of at least one of these members 10 has a central portion 15 of a diameter D1 equal to the minimum diameter of pipe on which the fitting is to be assembled, and further portions, disposed outwardly of the central portion 15, at each side thereof, of a diameter D2 equal to the maximum diameter of pipe on which the fitting is to be assembled. In this way the gap between the fitting and the pipe is reduced and the range of pipe diameters on which the fitting can be assembled to give a reliable seal is increased; i.e. fewer fittings are needed to cover a range of pipe sizes. One of the members 10 may include a saddle boss 12a having a recess 18 to accommodate a seal around an entry into the pipe. <IMAGE>

Title: A telephone dialler provides automatic selection of VF dialling or loop disconnect dialling to match exchange requirements
Inventor: BARNES GEORGE JOHN PRESTON
IPC: H04M1/30
Filed: 1989-03-18
Abstract: At the first key operation after power-on, the dialler detects the exchange dial tone and then sends the first digit only of the dialled number in VF mode to the exchange. If the dial tone is discontinued indicating acceptance of the signal the dialler remains in VF mode for further signalling. If however the dial tone remains indicating non-acceptance of the VF signal, the dialler switches to the loop disconnect mode. <IMAGE>

Title: Converting A/D nonlinearities to random noise
Inventor: WHITE BERT
IPC: H03M1/06
Filed: 1990-02-06
Abstract: For removing the effects of mismatched components in an A/D converter the capacitors of the A/D converter are dynamically rearranged so that physical mismatch is averaged out. An array of equally-sized capacitors C1-C8 is coupled to a switching network. A successive approximation scheme is implemented in which the input signal is coupled through SAR switches to the capacitor array. Each switch is coupled to 2<N-1> capacitors where N is the switch number. For example, in an 8-bit scheme, there are 3 switches with switch 1 coupled to one capacitor, switch 2 coupled to two capacitors, and switch 3 coupled to four capacitors. A scramble control code controls the switching array so that the capacitors are coupled to different SAR switches at different times. In this manner, the effects of any variations in the capacitance ratios is averaged out and converted to noise which can be filtered out of the signal.

Title: "Fuel injection control system"
Inventor: MONDEN HITOSHI
IPC: F02D41/04
Filed: 1990-02-22
Abstract: Engine speed Ne and throttle opening  theta  signals are used to estimate a rate of fuel evaporation Mf in the fuel supply system. The quantity of fuel to be injected Gf is calculated on the basis of the estimated fuel evaporation quantity and possibly an estimated fuel adhesion ratio X. A weighting factor  beta  which varies in accordance with the engine operating conditions e.g. rate of change of throttle opening  theta  or speed Ne is then used to generate a smoothed fuel injection control signal Gfn from a weighted mean value of the current fuel injection signal, and a previous smoothed signal. The current signal is more heavily weighted in transient operating conditions, and the previous signal in steady state conditions. The system may also incorporate feedback air-fuel ratio control. …<IMAGE>…
