Title: Direction indicator control unit
Inventor: ORTON RALPH HENRY
IPC: B60Q1/38
Filed: 1981-06-29
Abstract: A direction indicator control unit for a motor vehicle provides a self- canceling action after a predetermined period of time. Upon connecting the output 3 to an indicator bulb or bulbs via the direction selector switch, a set-reset bistable 10 is triggered automatically to activate a low frequency square wave generator 9 which via buffer 11 produces a signal at the output 3 for driving the bulbs. After a predetermined period of time, the bistable 10 returns to its original state and the generator 9 is deactivated. The predetermined period of time may be extended by applying a signal to the input 4, which may conveniently be wired to a warning light of the vehicle such as a brake light or neutral gear indicator which indicates the vehicle might be stationary and waiting to turn. The period may also be extended by a signal at either of terminals 16, 17, and a manually operated switch may be provided to extend the operating period. <IMAGE>

Title: Electrical pickup
IPC: G10H3/18
Filed: 1981-10-14
Abstract: An electrical pickup for a stringed musical instrument comprises a cylindrical permanent magnet 1 and a coil 6 surrounding the magnet 1 and wound lengthwise thereof. The ends of the magnet 1 are fixed to two rigid mounting wires 8, 9, and the coil is wound on a former 2 comprising a central tubular core 5 and two parallel plates 3, 4 fixed to the tube 5 which can turn on the magnet 1.

Title: Parallel operated inverters
IPC: H02M7/497
Filed: 1982-05-06
Abstract: Inverters 1 and 2 are connected in parallel at their a.c. outputs and each inverter has at or before its d.c. input side at least one circuit element 5, 6, 7 which assists in achieving current matching in controllable rectifier elements of the corresponding inverters which carry current simultaneously when the inverters are operating. In one embodiment two PWM motor drive inverter units 1 and 2 are connected in parallel between a three-phase constant frequency input 3 and a three-phase variable frequency output 4. Each unit comprises a diode rectifying bridge 5, a d.c. intermediate circuit comprising an inductance 6 and a capacitor 7, and a PWM thyristor bridge 8. The bridges 8 are controlled synchronously and good current matching in the simultaneously conducting thyristors of the two bridges 8 is achieved with the aid of the internal resistance of the diodes of the bridges 5, the inductances 6 and the capacitors 7, and output chokes 9 connected in the output connections of the two bridges 8. The corresponding output chokes may be coupled as in Fig. 3. <IMAGE>

Title: Data storage devices
Inventor: SAINT GEORGE
IPC: G11B7/003
Filed: 1982-11-30
Abstract: To provide a data store in which a data carrier (T) can hold a vast quantity of data and give rapid access, a format of parallel tracks is used each starting with a unique track identity number and a unique relationship to one or more longitudinal control tracks (B, C) which provide for high speed mode search, and low speed mode location, using video tape-recording servo-systems to surprising advantage. Coarse location of a required group of tracks may be provided by coded signal sequences on one control track (B1) and invididual tracks identified by coded signal sequence in a further longitudinal control track (B2). In one embodiment only the control track passes a reading head in the high speed mode, and in the slow mode the carrier is wound to half embrace a helical scanning drum carrying a plurality of heads. Read only devices may be provided for use as a reference source in library or computer installations possibly with multi-user and/or multi-bus facilities. Where required provision may be included for recording and/or read-out of stored data, but the control track sequence is preferably pre-recorded and constant. The data carrier can be in a preferred embodiment, a flexible tape in a cassette, but open reel-to-reel systems, short strips semi-rigid cards or rigid plates or drums can be used. The recording method can be magnetic or one of a variety of optical systems, and the data may be computer data, text, graphics video, or any combination thereof.

IPC: F01M13/04
Filed: 1983-04-15
Abstract: A centrifugal oil cleaner assembly, adapted to be mounted on a support at its upper end and to depend from the support, comprises a first housing member (1), a second housing member (110) sealingly engageable with the upper end of the first housing member to form a chamber, a substantially vertical shaft (70) mounted in the chamber, a rotor (10) carried by the shaft and within the chamber, the shaft serving to releasably secure the first housing member to the second housing member by means of a screwthread connection (113) and to carry the weight of the first housing member and the rotor, means (103, 112, 70, 72) for supplying oil to be cleaned under pressure through the second housing member to the interior of the rotor, said means including a passageway in the upper end of the shaft, nozzle outlets (14, 15) to discharge oil from the rotor into the chamber and by reaction cause the rotor to rotate, and an oil outlet (2) for removing oil from the chamber.

Patent GB-2123476-A (GB)
Title: Locking device
Inventor: YAMADA SHINJIRO
IPC: E05B65/20
Filed: 1983-05-25
Abstract: A power-driven automobile door locking device is of the basic type wherein a conventional rotary bolt is engaged by a ratchet lever 11 which may be released by operating lever 42. The device has a lock lever 31 having a locking position in which the latch is not releasable and an unlocking position (Figures 5 and 6 not shown), between which it is moved by a motor M. The motor rotates a disk 63, which has an essentially spiral cam groove 70 in its surface. A cam follower 76 engages with this groove 70, and, as the disk is rotated, is caused to move radially of the disk. The radial movement of the cam follower 76 is transmitted to the lock lever 31 through any suitable mechanism, such as lever 75 and lever 80, keyed to lever 31. The rotary disk may be replaced by a rotary cylinder having a cam groove in its cylindrical surface (Figure 19, not shown). The motor output is thus amplified, driving the locking lever 31 completely into its locking and releasing positions, overcoming the resistance of any over-centre spring. In the modified groove shown in Figure 26 only edge parts 147b, 148b have any camming action; parts 147a and 148a are of constant radius. The groove is widest at its mid-point, which is the rest position. <IMAGE>

Title: Electroplating non-metallic surfaces
Inventor: MORRISSEY DENIS M
IPC: C25D5/54
Filed: 1983-06-28
Abstract: In a method for electroplating non-metallic surfaces on a substrate (e.g., of plating hole walls in metal clad laminates), metallic sites are formed on the surface to be plated and the resulting site-containing surface is electroplated by means of an electroplating bath comprising a component (e.g. a dye, surfactant, chelating agent, brightener, levelling agent or pyrophosphate ions) which causes the plating to preferentially occur at the sites in comparison to the plating on surfaces of the same metal as the one plated out; whereby an increased rate of plating on the site surfaces is achieved with respect to the plating reaction on a surface consisting of the metal to be plated out. The method allows non-metallic surfaces to be rapidly and uniformly electroplated, without the need to electrolessly plate the surfaces first.

Patent GB-2135019-A (GB)
Title: Gas spring for vehicle boot lid
Inventor: FREITAG HERBERT
IPC: F16F9/02
Filed: 1984-01-12
Abstract: A flap member, e.g. a trunk lid of a motor vehicle, is pivotally mounted on a framework, e.g. a motorcar framework. The flap member is assisted in its upward movement by a gas spring. The thrust of the gas spring biases the flap member towards an upper position. In this upper position further upward movement of the flap member is locked by a relief pressure valve between the working chambers of the gas spring. By applying external force to the flap member assisting the thrust of the gas spring, the flap member may be moved beyond said upper position while opening said relief pressure valve. If the external upward directed force ceases the relief pressure valve closes again and the flap member is maintained in the new position by the thrust of the gas spring and the locking action of the relief pressure valve. When the flap member is to be lowered, an external force is applied opposite to the trunk lid and as a result thereof a direction-responsive is opened in parallel to the relief pressure valve.
