Patent GB-2149570-A (GB)
Title: Piezoelectric transducer
Inventor: BULTER ALFRED L
IPC: H01S3/086
Filed: 1984-12-11
Abstract: A transducer comprises a piezoelectric element (88) of quadrilateral shape which is mounted upon a flexure spring (86). One surface of the piezoelectric element (88) is coated with a metallic material forming electrodes which permit a potential difference to be applied across the element for flexing the spring (86). The metallic coating is interrupted to form first and second electrodes (94, 96). The piezoelectric element thus is driven by a voltage source (68) connected to the first electrode (94) while a sensor (70) connected to the second electrode (96) generates a sensor signal for sensing the flexure of the spring. <IMAGE>

Patent GB-856036-A (GB)
Abstract: 856,036. Workmen's time-recorders. INTERNATIONAL BUSINESS MACHINES CORPORATION. March 21, 1958 [March 21, 1957], No. 9221/58. Addition to 849,097. Class 106 (4). The elapsed time recorder of the parent Specification is modified in that the digit printing and overprinting drums are combined in a plurality of coaxial drums 2, 3, 4, 5, each having marking strips 7 alternating with strips 6 of digit types. The drum 5 is clock-driven and there is carry mechanism from one drum to the next. Drums 15, 16 for printing the date and time are arranged adjacent the first and last drums 2, 5 and an impression roller 11 on a mounting bar 13 movable toward and away from the drums can cause printing on an inserted card selectively from the drum 15 and the digit types of the drums 2 to 5 at the beginning of a job and from the drum 16 and the marking strips 7 at the end of a job. Pawls 18 and levers 19 control the registration of type or marking strip and interposers 28 suppress a carry operation when the subtraction demands it. An interposer 28 is electromagnetically operated during the end of job, overprinting operation by contact of the roller 11 through a hole 25 in the zero position of the row of digits already printed on the card with a conducting marking strip r. Each marking strip has a gap in zero position and is non-conducting to the left l of the gap and conducting to the right r. Thus when overprinting type from row 26 with the marking strip of row 24, contact is made through hole 25 with conducting strip r and the interposer acts but when overprinting type from row 21 with the marking strip of row 24 the hole 22 overlies a non-conducting strip l and the interposer remains inactive. The holes 22, 25 are burnt in the card during the initial printing by a spark from the roller 11 to an electrode 17 in the zero position of the type strip then registered for impression. The ink used to print the digits may be invisible and instead of overprinting a chemical developer may be applied to the area on the card corresponding with the gap in the marking strip.

Title: Light emitting diode operating circuit
Inventor: DEWHURST ALAN
IPC: H05B45/59
Filed: 1986-05-12
Abstract: A lift indicator assembly comprises light emitting diode means 10, and switch means 15, which may comprise a relay or a transistor, thyristor or other semi-conductor device, for disabling said diode means 10. Said switch means 15 are arranged to short-circuit said diode means 10 and alternatively or additionally to disconnect said diode means from a voltage supply near said diode means, when said diode means is in an "off" condition. The arrangement prevents operation of the diode means 10 by spurious voltages. <IMAGE>
Patent GB-2177321-A (GB)
Title: Dust filter
Inventor: PHILLIPS RICHARD HUGH
IPC: B03C3/155
Filed: 1986-06-19
Abstract: A filter for removing dust from a gas flow includes a number of fabric bags (30) on wire cages (36) and supported at their open ends (34) by an insulating plate (14). End portions (54) of the bags (30) remote from the plate (14) are restrained by engaging with complementarily- shaped end-cups (68) which prevent the bags (30) from wobbling when exposed to a gas flow. Adjacent bags (30) are raised to high voltages of opposite polarity so that dust deposition takes place in an electric field, and hence the dust cake is relatively porous. The end-cups (68) prevent the bags from shaking, which would cause sparking. End- cups (68) are spring-loaded and adjustable (Fig. 3) on support bars (48). <IMAGE>

Title: Gear pump in a hydraulic actuator control
Inventor: JOELSON KARL EVERT
IPC: F04C14/06
Filed: 1986-08-28
Abstract: A control for a hydraulic actuator (10, Fig. 1) forming part of a hydraulic circuit, includes a gear pump 19. In order to cause a cyclic pressure variation in the fluid delivered from the pump, at least two neighbouring teeth 39, 40 at a point of the circumference of one of the gear wheels 19b are cut to form a passage 41, which at least at the gap between the two teeth has a depth substantially corresponding to the height of a tooth, whereby a short-circuit connection between the pressure side 20a and its supply side 21a is formed when the said teeth engage teeth in the juxtaposed wheel 19a. In an alternative arrangement passages are cut to about half tooth- depth in neighbouring teeth on each gear wheel and the wheels are arranged so that teeth with the passages cut therein on one wheel co-operate with the corresponding teeth on the other wheel (Fig. 3). <IMAGE>

The bed is preferably of uniform section between the headstock and tailstock pillars, and, together with at least the sides of the headstock pillar and the tailstock pillar, may be fabricated from steel plate of constant thickness. Preferably also the headstock spindle (3) and the tailstock quill (4) are of substantially equal diameter, and they are adjustable to suit the length of the workpiece. <IMAGE>

Patent GB-2198237-A (GB)
Title: Tactile force sensor
Inventor: FINCH JOHN WILFRID
IPC: G01L1/20
Filed: 1986-11-17
Abstract: A tactile force sensor comprises a tube or sleeve (1, Fig. 1a) of conductive rubber or similar material with a core (9) of a highly electrically conductive substance within the sleeve. The composite sleeve and core may be positioned across a similar element or sleeve (2) of highly conductive material, force applied at the crossing node being sensed by varying electrical resistance between the crossed conductors. A plurality of sleeves (1) and (2) can be arranged to form an orthogonal matrix. In an alternative embodiment the sensor element forms a short cylinder (10, Fig. 3) which is axially compressible by a plunger against an annular contact (13) to vary the resistance between that contact and the conductive core of the element. <IMAGE>
Patent GB-2199202-A (GB)
Title: Electric power regulator snubber circuit
Inventor: TURNER NICHOLAS MALCOLM HOLMES
IPC: H03K17/0814
Filed: 1986-12-24
Abstract: A switching voltage regulator such as a step-down (Fig. 3), flyback or boost regulator has a capacitor C1 and diode D1 snubber circuit to assist turn-off of a semiconductor switch S and utilises transformer coupling with the inductive element L to derive a snubber capacitor charging current in a charging circuit 20 without the losses associated with charging resistors. The inductor L is formed as a primary winding Ts1 of a transformer Ts and the charging circuit 20 has two opposed secondary windings Ts2, Ts3, of half the number of turns. Ts3 with diode D3 and capacitor C2 forms a voltage storage circuit and Ts3 is part of, or coupled to, an inductance L1 which with diode D2 effects voltage doubling in charging the snubber capacitor C2. Switch off generates voltage in the storage circuit of Vout/2 and in Ts2 a voltage of Vout/2 which opposes it. Switch-on generates a voltage of (Vin-Vout)/2 in Ts2 which adds to the storage voltage of Vout/2 and applies charging current to the snubber capacitor at Vin/2 which is doubled to Vin as required. The inductive element may be a coupling transformer in a transformer coupled regulator. <IMAGE>

Title: A fuel injection pump for internal combustion engines
Inventor: EHEIM FRANZ
IPC: F02M45/12
Filed: 1987-12-15
Abstract: A fuel injection pump of the distributor type wherein a pump piston (4) is driven in a simultaneously reciprocating and rotating manner, the piston being provided with a relief passage (14) connecting the pump working chamber (6) to a relief chamber (7) and the relief passage (14) having discharge ports (16) controlled by an annular spool (18) displaceable and rotatable on the pump piston. In order to achieve low injection rates each discharge port is extended in the axial direction by a rectangular recess (77) into the forward face (78) of which leads a longitudinal throttling groove 80 opened by registration with a control groove (51) in the end face of the annular spool (18) before final opening of the discharge port (16) occurs. By operating a device (52) for rotating the annular spool, the controlling effect of the throttling grooves (80), and hence the quite-idle control of the fuel injection pump, can be cut out. <IMAGE>
