Abstract: 1,003,211. Air cushion vehicles. WESTLAND AIRCRAFT Ltd. Nov. 13, 1962 [Nov. 21, 1961], No. 41543/61. Heading B7K. An air cushion vehicle has a rigid base provided with flexible downwardly extending skirting or air trunking which may be retracted so that the vehicle can be used as a boat, or lowered on to a hard standing, by drawing the free or lower edge thereof towards the base so as to be distorted in a predetermined manner from its shape when extended, avoiding indiscriminate crumpling. Fig. 1 shows a section through an annular trunking 5 attached to a rigid buoyancy platform 3 and the outer wall 1 of a peripheral curtain-forming duct 4. The trunking is composed of outer and inner annular walls 6, 7, of rubber, rubberized fabric, or plastic, releasably attached to wall 1 and platform 3 by hinge and drawpin assemblies 9 (see also Fig. 3). Shaping and strengthening diaphragms 18, 19 connect the walls 6, 7, and impart a rearward component of velocity to the air in the curtain to effect propulsion (see Fig. 2). Cables 15 within the duct 4 are attached to wall 7 at points 17 by inverted Y ties 16. When the cables are pulled, the trunking assumes the section shown in broken lines in Fig. 1, with folding of wall 7 at 13. Where the periphery is curved, as is seen in Fig. 3, the trunking must contract in the peripheral sense, and the ties 16 effect contraction of alternate sections 12 as at 14, sections 11 remaining taut. Cork blocks 21 maintain the nozzles close to the water surface so that a cushion is formed correctly when the vehicle is to rise from the water after use as a boat. Flexible stabilizing keels may be similarly retracted.

Abstract: 966,598. Transistor gating circuits. GENERAL ELECTRIC CO. Ltd. Nov. 20, 1962 [Nov. 24, 1961], No. 42208/61. Heading H3T. In a gating circuit in which an oscillatory signal is passed by the gate when a first control signal exceeds a second, the gate is held open at least for a predetermined minimum time, even if the first control signal exceeds the second for less than this time. If the potential applied at terminal 1 is less than that at terminal 2, transistor 3 is cut off, transistor 6 is only slightly conducting and transistor 15 is cut off, preventing a square wave signal applied to terminal 19 from reaching the output terminal 24. If terminal 1 becomes more positive than terminal 2, transistors 3, 6, 15 become fully conducting, and the input at 19 is passed by transistor 15 to the output 24. Part of the square wave output at the collector of transistor 15 is rectified by diode 27 and is applied via capacitor 28 to bias transistor 6 in the conducting direction, so that this transistor, and hence transistor 15, will remain conducting at least until the change in charge on capacitor 28 is completed even if the potential at terminal 1 drops below that at terminal 2 before this time.

Filed: 1959-12-17
Abstract: 924,506. Transistor circuits; phase detectors. SQUARE D CO. Dec. 17, 1959 [March 23, 1959], No. 42877/59. Addition to 847,392. Classes 40 (5) and 40 (6). [Also in Group XXXVI] In a metal detector (see Group XXXVI) the output from a pair of pick-up coils 14 is fed to the base of each transistor 19, the emitter/ collector circuits of which are supplied with pulses obtained by rectifying the output of transformer 23c. Each output coil 14 is connected to form a partially resonant circuit with capacitors 17 and resistors 16. The values of capacitors 17 and resistors 15 are selected so that, in the absence of metal near the cores 11, positive half-cycles occur at the base of each transistor during the positive half-cycle at the emitter so that neither transistor conducts. In the presence of metal in the region of either core 11, the coupling between the nearest driving coil 12 and the output coil 14 is increased so that the phase of the output voltage tends to be reversed. The transistors 19 will only pass collector current when a metal article is present in the vicinity of both cores 11. The voltage developed across resistor 25 will then overcome the negative bias across capacitor 46, allowing the gas tube 29 to strike, energizing relay 35. The system is described as having an AND logical function. Rectifier 37 provides quiet relay operation by delaying the release at the end of each current pulse through valve 29. The phase of voltage may be reversed on one or more cores 11 so that the absence of a metal object would cause the corresponding transistor to become conductive.

Abstract: 1,057,370. Copying in colour by scanning. P. J. KYTE. Oct. 23, 1964 [Nov. 8, 1963], No. 44261/63. Heading H4F. Electrical colour correction equipment for use in colour printing wherein electrical colour separation signals are generated in response to photo-electric scanning of a coloured picture through colour filters, comprises means for correcting each separation signal, the correction comprising the addition to the separation signal to be corrected of the positive or negative difference between said signal and another separation signal attenuated on a basis which is different according as said difference is positive or negative. The circuit shown is for a " magenta separation," similar circuits being provided for the yellow and cyan separations. The three input signals D M , D C , and D Y  are proportional to the densities of the original picture through green, red and blue filters respectively, the density being a logarithmic function of the transmittance or reflectance of the original picture. The unconnected magenta input signal D M  has the unconnected cyan input signal D c  subtracted from it in the circuit marked Subtract 1, and according to whether the result of this subtraction is positive or negative it passes through either diode D1 and potentiometer P1 or diode D2 and potentiometer P2, and is then added to the original magenta input signal D M  in the circuit Add 1. Similarly the input signal D M  has subtracted from it the yellow input signal D y  in circuit Subtract 2, the resultant signal being fed via diode D3 and potentiometer P3 or diode D4 and potentiometer P4 to the circuit Add 1 where it is added to the input signal. According to the Specification, to give a correct separation it is necessary that D M  should be reduced in the so-called " White " colours-yellow, cyan and green, and increased in the so-called " Black " colours-orange-red and magenta, and the purpose of the circuit is to separate the correction process for the " white " colours and the " black " colours so that independent adjustment is possible for each. If A.C. signals are used instead of D.C. signals the discriminating circuits i.e. diodes D1-D4, are replaced by phase discriminating circuits. The signal-noise ratio when scanning very dark greys may be improved by incorporating a threshold value in the discriminating devices.

Abstract: 1358056 Battery charger YUASA BATTERY CO Ltd 28 Sept 1971 45132/71 Heading H2H Apparatus for charging one or more batteries utilizes excess power generated by a vehicle alternator. As shown, the input 1 is connected to, e.g. the cigarette lighter plug in a vehicle and a charging current is passed to one of the two series connected six volt batteries 9, 10 via the relays 3, 5, 6 and 7. In operation when the voltage at 1 reaches, e.g. 12À5 V the current flowing through the coil of relay 3 is sufficient to close the relay contact 3a and to pass the current through the coil of relay 5 which operates to close both contacts 5a and 5b when the input voltage reaches, e.g. 13À7 V and thereby to activate a square wave generator 8 which alternately closes relay contacts 7a, 6a to charge batteries 9, 10 alternately. Prior to the activation of relay 5, current flows through the coil of relay 3 via resistances V 1 , V 2  in parallel, but after activation and movement of the contact 5a, V 2  is removed from the circuit and the current in the coil therefore falls. If now the input voltage at 1 falls to e.g. 12À6 V, the current in the coil of relay 3 falls to a level to open the contact 3a and discontinue the charging process. In a modification, Fig. 2 (not shown), current is supplied to the main relay (15) via the emittercollector path of a transistor (16), the potential applied to the base of which is reduced, after activation of the relay by the insertion of resistance (V 4 ) into the circuit and thus the "on" and "off" voltage values may be accurately controlled.

Abstract: 1,059,114. Transistor switching circuits. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Nov. 5, 1964 [Nov. 19, 1963], No. 45652/63. Heading H3T. A circuit for indicating when a voltage varies outside predetermined limits comprises a bistable trigger circuit to which is applied an A.C. switching signal which, if the monitored voltage is within its predetermined range, switches the trigger circuit between its two stable states. If the voltage is outside the predetermined range, it provides sufficient bias to inhibit the switching action, and the circuit remains in one or other of its stable states. The bi-stable circuit comprises a pair of cross-coupled transistors T2, T3, Fig. 4, to which the monitored voltage and a square wave A.C. signal are applied via resistor R5. When the voltage is within its permitted range the circuit is switched between its two states by the A.C. square wave signal to produce an output signal which is fed via transistor T, Fig. 2, to a rectifier D1 and relay L. Relay L is thus held energized as long as voltage lies within its permitted range. The limits of the permitted range may be adjusted by providing an adjustable bias for the trigger circuit, and by adjusting the amplitude of the square wave signal, Fig. 1 (not shown).
