Patent GB-2204920-A (GB)
Title: Fuel distributor injection pump
Inventor: GOLLE HERMANN
IPC: F02M41/12
Filed: 1987-05-22
Abstract: A distributor injection pump for an internal combustion engine comprises a pump piston (2), which carries out stroke and rotational movements and on which a delivery quantity control member is mounted, the member being in the form of an axially fixed regulating ring (12) which rotates with the piston (2). A regulator system adjusts the angular relationship between the regulating ring and the piston (2). The change in the angular relationship alters the relative angular position of several mutually associated pairs of control output openings (13;14) in the piston (2) and the regulating ring (12). Since one or other of each pair of control output openings is inclined to the cross-sectional plane, a change in the angular position results in a change in the piston's stroke before a pair of openings become aligned. This alignment causes fuel to spill from the working chamber (11) so ending fuel delivery. Several constructional forms for the regulator system are described. <IMAGE>

Title: A friction clutch for a vehicle
Inventor: HIGGINBOTTOM CHARLES
IPC: F16D23/14
Filed: 1987-06-05
Abstract: The clutch includes a clutch release mechanism comprising a first member 15, a second member 13, a detent 20 arranged to locate the first member relative to the second member on assembly by moving the first member in one direction B relative to the second member whereby a clutch release force subsequently applied to said first member in an opposite direction A will be transmitted to said second member to release the clutch, and detent release means 25 which enables the detent 20 to be released by urging said first member 15 further in said one direction relative to said second member 13 so that the first and second members can thereafter be separated. A frangible element 30 in the form e.g. of a ring which may be fractured, is arranged between the first and second members to inhibit accidental release movement of the first member relative to said second member in said one direction and which can be fracture to permit release movement of the first member. <IMAGE>

Title: A key ring
Inventor: BILLINGS GEOFFREY MARTIN
IPC: A44B15/00
Filed: 1988-02-05
Abstract: A key ring comprises a metal frame 10 bent from thick wire to form a loop portion 11 from which extend two spaced curved arms 12 and 13. The arms 12, 13 engage within a peripheral groove 15 around a circular metal disc 14 which is formed with a recess 19. The disc 14 can be rotated from a position as shown where the recess 19 faces the loop 11 to a position (fig 3) where the recess 19 registers with a gap 18 between the ends of the arms 12 and 13. A key is fitted to the key ring by inserting the key partly into the recess 19, when it is in register with the gap 18, and then rotating the disc 14 to thread the hole in the key onto one or other of the arms 12, 13 (fig 2). The recess 19 is eventually brought into register with the loop 11 so that the key passes on to the loop and is safely retained. <IMAGE>

Patent GB-2210680-A (GB)
Title: Float controlled valve
Inventor: WHITFORD JOHN
IPC: F16K31/34
Filed: 1988-10-07
Abstract: An automatic float-controlled valve (87) has a float chamber (72) with a float (71) bearing a ferromagnetic member (76) displaceable vertically therein in dependence on the level of liquid in the chamber. A gas valve (73), sealed from the chamber (72) by a resilient membrane 41, has an inlet (69), an outlet (79) and a valve shutter (95) connected to a magnet (94) which holds the valve shutter (95) over an opening (100) between the inlet (69) and outlet (79) unless the float (71) descends in the float chamber (72) to a critical level where magnetic attraction between the ferromagnetic member (76) and the magnet (94) causes the latter to rise lifting the valve shutter (95) from the opening (100) and allowing communication between the inlet and outlet of the gas valve. The float chambers (72) of two such valves are arranged in the delivery lines from respective beer kegs. A switching valve (Figs 1 and 2) selectively connects the kegs to a delivery tap. When the connected keg is emptied, the float in the associated valve (87) will drop to the level at which the valve will open and actuate the switching valve to connect the other keg. <IMAGE>

Patent GB-2226201-A (GB)
Title: Microwave power amplifying arrangement
Inventor: HOWARD KEVIN RICHARD
IPC: H03F3/60
Filed: 1988-12-01
Abstract: A microwave power amplifying arrangement 20 (Fig. 3) comprises a plurality of microwave sources 30 which oscillate in sympathy with microwave energy injected via aperture 33 and deliver energy via the aperture. The sources 30 are arrayed about a cylindrical boundary wall 26 of a radial splitter-combiner 24, in which a circular bi-conical cavity is defined by the wall and inwardly projecting conical end-pieces, and are coupled to the cavity by way of apertures 34 in the boundary wall. An injection/output point 29 receives source injection energy from generator 21 via circulator 22 and provides combined energy of sources 30 to load 23. Although most of the source power is coupled into the cavity along the taper towards the injection/output point some forms a mode which travels along the boundary wall of determinable wavelength and if the boundary wall apertures are spaced an integral number of such wavelength apart the source 36 outputs are also injected into other sources so that the sources lock to each other in frequency and phase as well as to the injection energy and the reduction in injected signal needed to lock each oscillator enables more sources to be used to give greater power output. <IMAGE>

Title: Process and apparatus for attemperating tools for processing thermoplastic masses
Inventor: ZEPPENFELD REINHARD
IPC: B29C45/73
Filed: 1989-03-07
Abstract: In order to provide a process for attemperating, tools for injection moulding, by means of cooling water, in which process the tools possess several cooling channels which are each connected through inlet and outlet connections to a flow through device for controlling the cooling water, and all the inlet and outlet connections to the flow through regulating device open into common inflow and outflow channels in which, respectively, the cooling water is supplied through a pre- attemperating device and the returning cooling water is fed to the pre-attemperating device, and with which process a self-contained heating or cooling of the tools to the desired temperatures is possible, it is proposed that the pre- attemperating device controls the temperature of the flow in the pre-attemperating circulation by means of a temperature controller in such a way that during heating, the highest target temperature value of the flow through controller target temperatures, plus an excess, is chosen as the control variable and that heating is continued until the highest flow temperature so defined is reached, and after this highest temperature is reached the temperature controller is automatically switched off, and then the lowest target temperature value, minus an excess, of the flow through controller target values is then chosen as the control variable during cooling.
Patent GB-2217128-A (GB)
Title: D/a converter for 2's complement digital signals
Inventor: SHIODA FUMIO
IPC: H03M1/00
Filed: 1989-03-15
Abstract: A digital-to-analog (D/A) converter for converting a n-bit digital 2's complement signal to an analog signal. The D/A converter consists of a controller, a capacitor array, and a switch array. The controller operates to convert a 2's complement digital input signal into a 1's complement digital signal. The capacitor array consists of (n-1) capacitors each being connected at one electrode to a common output terminal. The switch array consists of (n-1) switches each connected individually to the remaining electrodes of the (n-1) capacitors. The switch array applies either one of a first or a second reference voltage to the (n-1) capacitors in response a second controller signal. An additional capacitor and switch are connected to the capacitor and switch arrays which serve to convert a digital signal from 2's complement to 1's complement. The additional switch, unlike the other switches, feeds either the first or second reference voltage to the additional capacitor in response to the first controller signal, or it feeds the first reference voltage in response to the third controller signal.
