Title: Windscreen Cleaning Systems
Inventor: BRITTAIN WILLIAM JAMES
IPC: B60S1/52
Filed: 1968-12-31
Abstract: 1,198,770. Windscreen cleaning systems. FORD MOTOR CO. Ltd. 31 Dec., 1968, No. 61796/68. Heading A4F. [Also in Division F1] In a windscreen cleaning system a roller mounted on a windscreen wiper drive mechanism rolls along a resilient tube to pump liquid to a windscreen washer jet. A flexible tube 22 through which liquid flows from a reservoir to a jet 42 (Fig. 8, not shown) is held in a channel 20 biased by a leaf spring towards the path of a roller 16 carried by a crank 14 rotated by an electric motor 10 and driving windscreen wiper mechanism via a link 17. In operation of the windscreen washer the tube 22 is positioned to be compressed by the roller 16 which passes along the tube to pump liquid to the jet, non-return valves being provided between the tube and the reservoir and between the tube and the jet. When windscreen washing is not required the tube 22 may be withdrawn to an inoperative position by a cable 25. In an alternative embodiment the channel 20 is formed in a backing member 27 (Fig. 5, not shown) supported by spring clips. Arrangements are described (Figs. 7 to 11, not shown) whereby washing liquid may be passed through a hollow windscreen wiper spindle to a jet carried by a wiper arm.

Title: Method of recording and apparatus for automatically reading binary data
Inventor: APANJERSBERG ARIE ADRIAAN
IPC: B07C3/14
Filed: 1969-12-22
Abstract: 1279878 Sensing records NETHERLANDS POSTAL & TELECOMMUNICATION SERVICE DIRECTOR GENERAL OF 22 Dec 1969 [3 Jan 1969] 62357/69 Heading G4M Data is represented by a row of typewritten dots, e.g. a "1" is represented by a dot and a "0" by a space followed by a dot. The data may be typed on a document so as to be visible through an address window in an envelope. The row of dots is sensed by two obliquely transverse rows of photo-cells fa-fe and ff-fi, Fig. 3, the outputs from which are fed to a selecting device, Fig. 6, which selects the three photo-cells centred on a sensed dot and provides a pulse p1 or p2 for each dot sensed by the cells fa-fe or ff-fi respectively. The pulses p1, p2 are used to generate clock pulses S (the distance between the rows of cells corresponds to the spacing of the code elements) and allowance being made for the possibility that only p1 or p2 pulses occur. A register section delays the p1 pulses by one element period, and a processor converts the data to a train of binary bits which are supplied to a shift register together with shift pulses, input to the shift register being blocked when a start bit arrives at the final register stage. The processor suppresses the shift pulse associated with the dot pulse of a binary 0. The number of dot pulses is counted and the count is checked for correctness when the detection of two successive spaces signifies the end of the code.

Title: Ratioless two phase shift register bit
IPC: H03K19/096
Filed: 1979-12-14
Abstract: A ratioless two phase shift register bit constructed in MOS technology in which in order to reduce the chip area occupied by the bit and to improve both the "high" and "low" signals use is made of kick-up capacitors (T9, T10) coupled between the gate and source of enhancement transistors (T7, T8) serving as transfer and store (TAS) gates. The shift register bit further includes first and second sticks of three transistors (T1 to T3 and T4 to T6) with the TAS gates (T7, T8) connected at one side to a junction (10, 12) of the first and second transistors (T1, T2 and T4, T5) of each stick and at the other side either to the centre transistor (T5) of third transistor (T6) of the next stick in the progression of the signal or to an output (Q) which will be connected to the input (D) of the next shift register bit, which input is the gate of the centre transistor (T2) or third transistor (T3) of the first stick in the next shift register bit. The two transistors of each stick to which the data signal is not applied are clocked in antiphase to each other and each TAS gate (T7 and T8) is clocked in phase with the gate of the first transistor in the next stick in the progression of the signal. Conveniently the kick-up capacitors may comprise depletion or enhancement transistors of the same conductivity type as the other transistors or may be fabricated by a double metallisation process. <IMAGE>

Title: Apparatus for the Production of Curable Resin Foam
IPC: B29B7/74
Filed: 1980-04-01
Abstract: Curable resin foam, particularly of urea-formaldehyde resin, is supplied in small quantities intermittently from an apparatus as shown. Resin or hardener, together with a surfactant, is passed through conduit 21, and compressed air is passed through conduit 20, into a foaming chamber 22. The unstable foam which forms is passed to a series of outlets 31 in the base of the foaming chamber. That component (hardener or resin) which is not supplied through conduit 21, is passed through conduit 32, via a non-return valve 30 and conduit 33 to outlets 31. The resin and hardener then mix and the separate streams are discharged into cone 28 and out as a single stream through outlet 29. When sufficient foam has been discharged, the flow of components and compressed air through conduits 20, 21, and 32 is stopped and a purging fluid, such as compressed air, is passed through conduit 32' to eliminate last traces of the curing foamed mixture from the apparatus. <IMAGE>

Title: Temperature detecting circuit
IPC: G04F5/06
Filed: 1980-05-19
Abstract: A circuit for compensation of timekeeping inaccuracies induced by ambient temperature variations. A bridge circuit having a temperature sensitive resistive element in one branch and a resistance of programmed variation in the other branch outputs a changing unbalanced voltage to drive a comparator. A change in polarity of the comparator output detects the ambient temperature and causes a counter controlling the programmed resistance to output signals to a timekeeping regulation circuit whereby timekeeping is made accurate. Initial corrections are made in the programmed resistance branch to adjust for off-design performance of the vibrator in the timepiece oscillator.

Title: Optic fibre connector
IPC: G02B6/38
Filed: 1980-10-01
Abstract: A fibre connector for joining two optic fibres 4 and 5 comprises strands 1 of a deformable material extending between two end members 2. The strands form with the end members a cage-like structure into which fibers 4 and 5 may be inserted from respective ones of the end members 2. The fibres may be gripped thereafter by causing the strands to twist around the fibres. The strands may be resilient and pre- twisted so that a connection can be made by untwisting them slightly, inserting the fibres and then releasing the strands so that they spring back and grip the fibres. Alternatively, the strands may be initially straight and manually twisted after inserting the fibres. The strands may be of metal. A permanent connection may be made by applying epoxy resin to the joint. <IMAGE>
