Title: A method and circuit arrangement for the realization of PCM-channel units of SCPC satellite-communication systems
Inventor: BACS ERNO
IPC: H04B7/208
Filed: 1985-04-26
Abstract: A method to centralize and restructure system technical jobs of PCM-channel units of SCPC satellite- communication systems during a sampling period. The system-technical tasks of a PCM-channel unit are restructured into parallel-in-time disjunct jobs and are grouped that way that we order to each computing element a job to be run at the same time - simultaneously - and at the end of the first job to each computing element a new job is ordered to be run after the first one also simultaneously during the same sampling period, and so forth... A circuit arrangement is invented in which a computing capacity of the computing elements is provided. The computing elements are communicating with each other and with other system elements via two-way common address/data/control bus-system. The computing elements are connected to an interrupt generator by means of interrupt connections. A common memory is connected also to the common address/data/control bus. The computing elements are connected to a switches-displays block, to a modem unit and to a codec unit via two-way ports and via a blocksynchron detector- also by means of the common address/data/control bus. <IMAGE>

Title: Coupling of vehicles for towing
Inventor: MARYGOLD JOHN
IPC: B60D1/40
Filed: 1986-02-04
Abstract: Coupling together a tractor and a trailer for towing presents difficulties in aligning the vehicles so that an eye on the trailer can be connected to a hook on the tractor, or vice-versa. A trailer has a mounting 2 incorporating an automatic coupling device 5. A drawbar 4 having outer and inner eyes 6, 7 is slidable in a spherical bearing 3 in mounting 2. Lever 14 unlatches and lifts locking pin 13 to release eye 7 so drawbar 4 can be drawn out. With tractor and trailer suitably positioned the spherical and sliding bearing 3 allows drawbar 4 to be manoeuvred to engage eye 6 on rotatable hook 8 of the tractor. Reversing the tractor with the trailer brake applied closes drawbar 4 into mounting 2. The tapered nose of eye 7 is guided by guide plates 11 and corresponding inclined side walls into the automatic coupling device and pin 13 enters bore 12 to engage eye 7 and the latch secures pin 13. The spherical bearing 3 may be replaced, for road vehicle couplings, by a trunnion allowing pivotting about a vertical axis. <IMAGE>

Title: Demodulation circuit
Inventor: RAMSDALE PETER ALAN
IPC: H04L27/156
Filed: 1986-07-12
Abstract: A zero IF receiver for data received as FSK demodulates in a series of steps: (i) I and Q signals which are in phase quadrature are derived 2-5; (ii) the I and Q signals are digitised 6,7; (iii) the I and Q signals as digitised are used to produce R (amplitude) and theta (phase) signals, which together define the modulation. In the present arrangement, the I and Q signals are derived to more than one-bit accuracy, and the plural bit digitised I and Q signals are used to access look-up tables 10 which give the  theta  signal, and possibly also the R signal. Then the  theta  and R signals together define the modulation. This is usable to detect data transmitted in radio pagers, cellular telephones, and cordless telephones. <IMAGE>

Title: Rail brake air regulator
Inventor: VALE GEORGE KEITH
IPC: B60T13/66
Filed: 1987-11-14
Abstract: An air pressure regulator for a rail vehicle has a source of air pressure (10) which is connectible to a brake actuator (22) either directly by means of a line (16) or alternatively via a pressure reduction device (18), the selection being made by means of a solenoid-operated valve (12). A control means (30) is fed with a signal representative of the brake speed v and compares the speed with the brake lining friction/speed characteristic which is stored in the control means. If the control means decides that the coefficient of friction of the brake lining at that brake speed is below a threshold valve, the source of air pressure (10) is connected directly to the brake actuator (22) instead of via the pressure reduction device (18). The invention compensates for the reduction in the coefficient of friction ( mu ) which occurs with increasing speed with relatively soft brake lining materials. <IMAGE>
