Abstract: 1,173,289. Mould. BOEING CO. 25 Nov., 1966 [18 Feb., 1966], No. 62800/66. Heading B5A. In a process in which fibre resin articles are moulded in a two-part mould, inserts are located at the junction of the mould parts in order to control the formation of flash. The gap between the inserts and the mould parts is sufficiently small to prevent the passage of fibres thus ensuring that the flash is composed solely of resin. When such flock is trimmed from the article the fibres are not exposed to the surface of the article and the strength and appearance of the article is preserved. In the embodiment shown in the Figure, the mould comprises a fixed half 11 having a mould cavity 12, and a pivotable half 16, having a mould cavity 17, each half being provided with stops 13 and 18 spaced along their lengths. In the closed position of the mould the stops cooperate, as shown, to form channels 24 in which are located inserts 22 and 30. Upon closure of the mould on to the working material, the inserts are forwarded, through channels 24, to a position in which their operative faces are flush with the faces of the mould cavities, by means of levers 37. In a second embodiment (see Fig. 2, not shown) the upper channel 24 is done away with and the upper parts of the mould halves are extended so that they cooperate along an upper centre line.

Title: Gas discharge panel display
IPC: A47G27/00
Filed: 1970-11-13
Abstract: 1317663 Matrix displays INTERNATIONAL BUSINESS MACHINES CORP 13 Nov 1970 [15 Dec 1969] 54158/70 Heading G5C A wall storage type gas discharge display comprises a gas panel 10 with crossed sets of conductors H, V on opposite sides defining a matrix of discharge sites; and drive circuitry for applying square wave signal trains to all the conductors in each set sufficient to sustain a discharge and write voltages to selected conductor pairs which together with the sustain voltages ignite a discharge. The gas is 99À9% Ne and 0À1% A, the line drivers are integrated circuits and to maintain uniform operation pilot cells p1...p4 permanently on are provided at each corner of the panel. Operating potentials to the conductors are supplied by line drivers 21-24 and 51-54 which receive signals from sustain drivers 30, 60 and selection circuits 25, 55. The sustain drivers receive control signals from a circuit 70 and input lines 33, 63. Write and erase signals are supplied to circuit 70 on lines 81-86. Circuit 70 comprises 2 three transistor circuits which on actuation allows current of amplitude dependent on the input signal on line 83 or 85 to pass through a primary winding coupled via a ferrite core to secondary windings in drivers 30, 60. Pulse trains SH, SV on lines 33, 63 operate transistors in the sustain drivers to provide outputs PH, PV to operate the pilot cells and signals SH, SH+, SV, SV+, to the line drivers each comprising a transistor and constant current diode. In the sustain condition wave trains SH, SV, 90 degrees out of phase result in inverted identical signals being applied to the line drivers and hence to conductors H, V. In a write operation the sustain pulse duration is doubled and write pulses added to selected cells. The write pulses are added towards the end of the sustain pulses to allow existing discharges to settle to a steady state and cause least disturbance in adjacent unignited sites. Input signals on lines 81, 83, 84 to circuit 70 result in the addition of a pulse to pulse trains SH+ and SV- and the subtraction of a pulse from signals SH and SV. Signals from selection circuits 25, 55 determine if SH or SH +, SV or SV- are applied to the conductors. Only when SH+ and SV- are applied to a site is that site ignited, otherwise a pulse of sustain magnitude is applied. Subsequently a signal is applied to line 82 to reset the ferrite core then if required a write operation occurs at another site. In an erase operation the SH, SV drive inputs are changed to constant voltage signals. Signals on lines 81, 85, 86 result in a pulse being added to SH, SH+, SV and SV+ signals which is such that to a selected site a sustain pulse is replaced by an erase pulse of lower magnitude. This causes a weak discharge and reduces wall charges almost to zero. After a predetermined time all wall charges are lost and sustain pulses re-applied. To non-selected sites either no erase pulse or an erase pulse of opposite polarity as the sustain pulse is applied. In either case no discharge occurs so that wall charges are retained.

Abstract: 1459805 Battery cassette MABUCHI MOTOR KK 23 Nov 1973 [24 Nov 1972] 54600/73 Heading H1B [Also in Divisions E2 F4] A cassette for retaining a plurality of batteries 4 in two adjacent rows is formed of a unitary plastics moulding and includes no metal parts. As shown in Figs. 2 and 4 the cassette comprises a central longitudinal partition 3, end plates 2 each having a pair of apertures 2a, 2b, and two side walls 1 with lugs 1b on their two edges for resiliently retaining the batteries 4. Connection with the batteries is made by spring-loaded contacts which extend through the apertures 2a, 2b, these contacts being carried by the appliance into which the cassette is inserted for use. The apertures 2a, 2b and the spring-loaded contacts are of different size or shape to prevent use of the cassette with reversed battery polarity. In another construction of cassette. Figs. 8, the cross-section is of E-shape. A water-proof torch incorporating the cassette of Figs. 8 is described (Fig. 10, not shown). A bridging contact (16) with contact pins is urged by a spring (15) to engage the battery terminals through the apertures 2a, 2b whereby the batteries are connected in series. The other ends of the batteries are engaged by spring-loaded contacts and the torch is controlled by a pushbutton switch (23). The cassette may be employed in a water-proof hand tool (Fig. 13, not shown) in which batteries (67) drive a motor (31) driving an output shaft (34) through a reduction gear (32). Various tools may be selectively connected to the shaft (34) by a snap-connection described with reference to Figs. 15-17 (not shown), see Division E2.

Filed: 1966-12-13
Abstract: 1,137,959. Gating circuits. ENGLISH ELECTRIC CO. Ltd. 13 Dec., 1967 [13 Dec., 1966], No. 55805/66. Heading H3T. [Also in Division H2] A rectified timed output signal is obtained from a plurality of A.C.-fed thyristors which are fired sequentially by a train of pulses gated by a pulse of predetermined duration produced from the leading edge of an initiating pulse. In Fig. 1, such a circuit is used to energize the operating coil 11 of an electromagnetic circuit breaker at a precise instant. Unit 17 produces a pulse for each cycle of each phase of the A.C. supply and applies these pulses continuously to transistor 15. Unit 21 produces long negative pulses of much lower repetition rate which are differentiated by an RC circuit 18-20 and applied to transistor 16 to allow a certain number of pulses from 17 to reach transformer 14 and fire the thyristors T1-T3. These conduct sequentially in successive halfcycles of the A.C. supply and their conduction periods overlap to send a fluctuating D.C. pulse through the coil 11 (Fig. 2f, not shown). The commencement of this pulse is set by the instant of the first pulse from 17 which follows the leading edge of a pulse from 21. The duration of the pulse through the coil 11 can be varied by resistor 20 which determines how many pulses from 17 can pass through the transistors before transistor 16 is cut-off by the end of the differentiated pulse. The unit 17 can be an independent pulse generator of high frequency, in which case the leading edge of the pulse from 21 determines the start of current through the coil 11. The half-wave arrangement of T1-T3 can be replaced by a three-phase bridge using three thyristors and three diodes. Separate trains of phased pulses can be generated for each thyristor.

Abstract: 1404980 Motor vehicle brakes NORTH AMERICAN ROCKWELL CORP 4 Dec 1972 [3 Jan 1972] 55895/72 Heading B7H [Also in Division F2] In a vehicle antiskid braking system the braking pressure is temporary relieved upon detection of incipient wheel lock and then reapplied cyclically as the wheel accelerates. As shown, the system includes service reservoirs 38, 39 fed from a compressor, 36, charged reservoir 37 and respectively supplying air pressure to the control chambers 78 of valve assemblies 20, 20<SP>1</SP>, respectively provided on the front and rear axles 28, 35, by way of lines 42, 42<SP>1</SP> and treadle valve 40. Air pressure is also fed to an inlet port 54 of each valve assembly for connection, via a valve element 106, to an outlet 56 leading either to front actuators 22, 23, 24, 25 or rear actuators 29, 30, 31, 32 respectively. During normal braking treadle valve 40 is depressed to pass air pressure to control chamber 78 of each valve assembly by way of aperture 118 and flutes 121 provided in a shuttle valve member 110. A diaphragm 74 is thereby depressed causing a valve member 86 to move from a seat 90 permitting air to pass from inlet 54 to a quick release valve chamber 102 via passage 104 the pressure thus establishing unseating a valve plate 106 and allowing the brakes to be applied through outlet 56. Pressure builds up in a flow chamber 76 until eventually equilibrium is established across diaphragm 74 corresponding to the selected position of treadle valve 4. Upon brake release, pressure in chamber 78 is reduced to atmospheric and pressure in chamber 76 acts through one or more openings 103 to lift diaphragm 74 from seat 124 to connect chamber to a vent passage 58. If incipient wheel lock is detected a solenoid 70 is caused to be energized shifting valve member 100 rightwardly thereby closing aperture 118 and opening vent passage 116 to control chamber whereafter the brakes are released as if the treadle valve had been released in the manner described above. If the wheel lock signal to solenoid 70 is discontinued plunger 110 moves leftwardly under the influence of pressure differential and spring 114 bias thereby closing vent 116, while opening aperture 118 to restore the operator controlled braking. Thereafter the solenoid is cyclically displaced to connect chamber to pressure and to exhaust alternately. Wheel lock is detected by sensors 44 and toothed discs 46 feeding signals to a computer 75 bolted to the valve assembly which is itself bolted to the respective axle 28 or 35.
