Title: Vehicle location determining system
Inventor: MITCHINSON JAMES COLLIER
IPC: G01S1/24
Filed: 1991-04-02
Abstract: The location of a vehicle or person, G5 is determined by measuring the differences in time of arrival between pairs of line or frame synchronising pulses received from 3 different TV signal transmitters S1-S3. The measurements are corrected for relative system time delays or signal synchronising alterations that may occur between pairs of relevant TV transmitter sites by using similar timing differences measured at a suitable known location G4 which is in radio contact with the vehicle. The intersection of the loci of the deduced distances from the transmitter sites establishes the mobile location to a reasonable degree of accuracy. The location is either presented as a set of positional co-ordinates or can be superimposed on an electronic map display. <IMAGE>

Title: Fuel injection pumps for internal combustion engines
Inventor: ZIEHL MANFRED
IPC: F02M59/24
Filed: 1991-12-20
Abstract: In a fuel injection pump for an internal combustion engine, a pump piston (3) reciprocable in a cylinder (2) is rotatable for the purpose of controlling fuel quantity, and the cylinder (2) has a niche (4) which receives a control sleeve (5). The niche (4) has a planar inner wall (17), two sloping side walls (25), and two parallel opposed walls (22) which merge into sloping portions (24) and terminate in slideways (23). Baffle aprons (21) on the control sleeve (5) include slide surfaces which are guided by the slideways (23) to prevent rotation of the control sleeve (5) and at the same time serve to baffle fuel discharged through a spill passage (14) in the sleeve. This reduces cavitation and erosion damage. The wall thickness of the niche is substantially constant with respect to the cylindrical external shape of the pump cylinder (2). <IMAGE>

Title: Tally circuit.
Inventor: HOWARD DAVID WILLIAM
IPC: G06F7/60
Filed: 1992-03-03
Abstract: A tally circuit in which an N bit input word is split into an N-X bit input word and an X bit input word. These two words are each fed to partial tally circuits (12), (14). The result from one of these partial tally circuits (12) contains a marker bit with a position indicative of that partial tally count.

Patent GB-2265053-A (GB)
Title: Digital signal receiver and signal processor.
Inventor: WELLS MICHAEL COLIN
IPC: H01Q3/26
Filed: 1992-03-11
Abstract: A digital signal receiver provided with a beam forming array of antennas (a1...an) utilises a discriminator vector d to calculate a weighting distribution applied via respective multipliers m1...mn to the output of buffers (b1...bn) containing digitised values of the received waveforms. The sequences of digitised waveform samples stored in the buffers each include a sequence which ideally corresponds to a known sequence which is stored in a signal component store (6). The discriminator vector d initially consists of this known sequence and is subsequently refined by including the remaining samples derived from the combined and demodulated output signal by means of a modulator (3), the discriminator vector is then reconstructed (5), and the thus-modified discriminator is then used to refine the weighting distribution calculated by a digital processor (8). Further iterations may be performed if required. This arrangement is applicable to a frequency- hopping communications system for example. <IMAGE>

Entrainment members (fork units) (19) of the carousel structure (11) preferably relinquish the articles (P) before they reach the output conveyor (3) so that the articles (P) accumulate immediately upstream of the output conveyor (3). As shown conveyor (2) is a belt conveyor and conveyor (3) is a chain conveyor with nibs or dogs (101), the distance between which is selected in dependence on the number of articles (piles) in each group (e.g. three). The fork units (19) are caused to move by a cam (30), and the articles (P) slide arcuately on a plate (6), with an arcuate guide (100). M2 constitutes a wrapping or packaging machine. <IMAGE>
