Abstract: 1376807 Primary cells SAFT-SOC DES ACCUMULATEURS FIXES ET DE TRACTION 17 Nov 1972 [26 Nov 1971] 53374/72 Heading H1B A cell comprises a metal casing 3 in contact with a porous positive electrode 4 consisting of a compressed mixture of, e.g. powdered copper oxide, graphite, and a binder. A tubular sheet separator 5 applied against the electrode 4 is contacted on its inner surface by a negative electrode 6, e.g. of lithium. The electrode 6 is in the form of a sheet surrounding a tubular collector 7 of spring steel. The longitudinal edges of the collector 7 overlap, Fig. 2, and are not connected whereby the resilience of the collector, which tends to expand it, holds the components 3 .. 7 in contact with each other. In a modification, (Fig. 3, not shown), the collector edges do not overlap but are spaced by a small gap. An insulating cup 8 separates the components 6, 7 from the casing 3. A metal cover 1 sealed by a washer 2 to the casing 3 carries a steel blade 9 making connection with the collector 7. The copper oxide of the electrode 4 may be replaced copper sulphide, silver chromate or lead chromate. The electrode 6 may alternatively consist of sodium or calcium. The electrolyte permeates the electrode 4 and separator 5 and comprises lithium perchlorate dissolved in a mixture of tetrahydrofuran and dimethoxyethane, propylene carbonate or dimethyl carbonate. Excess electrolyte is contained in the space 10.

Abstract: 1,249,179. Video magnetic tape recording/reproducing. SONY CORP. 5 Nov., 1969 [19 Nov., 1968], No. 54268/69. Heading G5R. In a recorder employing a cylindrical tape guide drum 12, Fig. 1, having at least one rotary magnetic head 10, the magnetic tape extending between spaced take-up and supply reels (43, 44) is moved into engagement with the tape guide drum by a tape guide which moves in an arcuate path round the drum. When the ring- shaped guide member 15 is rotated, guide pin 19 carries the tape from a cassette 41 (Fig. 2, not shown) to the position of Figs. 4, 5 where the tape encircles the drum and further rollers are provided to hold the tape away from the drum where contact is to be avoided. Controls. Upon depressing play button 30, Fig. 9, lever 39 is rotated to release roller 18 from recess 16 in guide member 15 and also cause motor M to run and drive capstan 31 and pulley 8 which rotates upper guide drum 9 carrying the head 10 and balance weight 11. The lever also releases brake 81 and causes idler 86 to contact member 15 to rotate it anticlockwise. After one revolution the roller 18 re-enters the recess 16 and idler 86 ceases to drive the member 15. As the guide member 15 rotates, the tape 13 is wrapped around the drum as indicated above. Lever 37 also causes, through lever 112, brakes to be removed from wheels 61 (62) (Fig. 8, not shown) in the drive shaft to the pulleys which co-operate with the reels in the cassette, and also rotates plate 69 to move the pinch roller 32 towards the capstan 31 to drive the tape. Idler 118 is brought into contact with pulley 121 to drive wheel (62), thereby rotating take-up reel (43). When the stop button is depressed, levers 37, 39 are returned to their original position, the pinch roller moves away from the capstan and the tape is stopped. However, the drum 15 remains with the tape wound around the guide drum 12. When the rewind button 35 is depressed, lever 75 causes levers 88, 91 to move lever 17 to remove roller 18 from recess 16, and lever 95 causes idler 98 to contact member 15 and also wheel (63) driving the take-up reel (44). The member 15 is then rotated back to its initial position. If, when in the stopped position, the play button 30 is again depressed, a switch prevents the motor from driving the member 15 through a further revolution to avoid double winding of the tape. This result may also be achieved by a mechanical arrangement, Figs. 15 and 16 (not shown).

Abstract: 1400878 Ballistic computers HUGHES AIRCRAFT CO 24 Nov 1972 [26 Nov 1971] 54455/72 Heading G4G A ballistic computer provides a gun elevation-angle signal # for a selected ammunition and non-standard firing conditions using the power series # = aR s  + bR s R m  + cR s R m <SP>2</SP> where R s , R m  are functions of a target range signal R and of the respective differences between the initial velocity and the drag under standard and non- standard conditions for the selected ammunition. More particularly R s =R(1-V) and R m  = R(1-A) where, velocity variation and drag variation # and γ being coefficients characteristic of the ammunition type selected. Tg, EFC, T a  and P are normalized deviations from standard values T s <SP>0</SP> &c. of grain temperature, gun wear, air temperature and air pressure, respectively. For example, T a = (T a <SP>0</SP>-T<SP>0</SP> s )/(T s <SP>0</SP>) where the temperatures are in K. (other examples of deviation formulµ are given). The coefficients K and a, b, c are dependent upon the type of ammunition selected. The normalized deviation signals are generated and multiplied by R in the circuit of Fig. 4, where the wipers of potentiometers 50, 54, 56, to which the signal R is supplied, are driven by transducers 60, 68, 74. The deviation RTg is generated by a bridge circuit 52 containing thermistors responsive to gun temperature T g . Division by standard values is effected in the differential amplifiers 66, 62, 70, 72. The signals RV and RA are then generated in the circuit of Fig. 3 (which includes the circuit of Fig. 4) where the three terms of RV are formed in multipliers 76, 78, 80 and added in amplifier 82. Similarly the terms of RA are formed in amplifier 83 (to which signal RV is supplied), multipliers 84, 86 and amplifier 88. The signals RV, RA are subtracted from R in amplifiers 90, 88 to yield R s , R m . The signal R n  is demodulated and applied to a master multiplier 96 which provides a chain of pulses whose duty cycle is proportional to R m . These pulses are applied to time-division multipliers 98, 100 which form the terms in R s R m  of the power series for e. Coefficients a, b, c are applied by multipliers 92, 103, 104 and the terms added in amplifier 106. The various multipliers used to form the terms of RV and RA may each consist of an amplifier (Fig. 5, not shown) having one of a number of feedback resistors selected by respective FET switches actuated by an ammunition-selector signal. A time-of-flight signal t f  may be generated from the outputs of the Fig. 3 circuit and further ammunition-dependent coefficients, in accordance with the equation, in the circuit of Fig. 6 (not shown) where the terms are formed in separate multipliers and fed to a summing amplifier.

A generator for producing a sequence of output pulses upon the application of a single stepped input pulse derived from a generator 17 comprises a wafer 10 of single crystal ferroelectric material, e.g. barium titanate, provided on upper and lower surfaces, respectively with second and first electrodes 12, 11. The electrodes 11, 12 have substantially equal areas, the electrode 11 comprising a single disc and electrode 12 comprising concentric spaced element 13 . . . 16 connected to earth through capacitors 23 . . . 20. On the application of a pulse from generator 17 at time t 1  (Fig. 4, not shown) a step voltage appears across capacitor 20 at time t 2 , the delay being due to the time required for the alignment of the dipoles in that portion of the wafer 10 that is relatively free of mechanical restraint. At time t 2  the portion of wafer 10 between element 16 and electrode 11 has undergone polarization and ceases to restrain the adjacent wafer portion under element 15. As a consequence of the inward movement of strain current pulses due to the spontaneous polarization of the ferroelectric material result in voltages successively appearing across the capacitors 20 . . . 23. In a modification (Fig. 5, not shown) the upper and lower electrodes are of rectangular shape.

MICROCOMB STRUCTURES Ltd 24 Jan 1972 [23 Nov 1970] 55509/70 Heading B3A [Also in Divisions E1 and F2] A metallic body of fabricated cellular formation, e.g. an aerofoil section or honeycomb seal, wherein the cells are defined by an array of juxtaposed sheet metal elements 10a-10c, crossed with similar elements 11a &c. by the provision of slots such as the slots 14a-14e, Fig. 3, is made by a method comprising: forming each element from flat metal sheet by chemically etching away metal from around a blanked-off region of a metal sheet to provide a predetermined contour, e.g. suitable to define the aerofoil section shown, and thereafter assembling the elements in their predetermined relative positions and fixedly locating them relatively to one another through interengagement of the elements 10a-10e with the slots in the elements 11a &c. and vice versa. Some of the elements may be deformed prior to assembly in order to produce a curved body. In the aerofoil core shown, Fig. 5, the metal elements may be fixed together by spot welding, but preferably the fixing is effected by using nickel-coated sheet metal for the elements and, after assembly, heating the core in a vacuum or non-oxidizing atmosphere to cause the nickel to flow and create intimate metal-to-metal junctions between the elements at the junctions. Further strengthening may be provided at certain places by the use of metal slugs 18. The aerofoil may be located on the core by means of projections (not shown) on the latter which engage in slots in the aerofoil. In the case of a honeycomb seal (not shown), the cells may be filled with a thermosetting resin to give a solid external appearance to the seal.

Abstract: 1,196,830. Digital transmission systems. ING. C. OLIVETTI & CO. S.p.A. 27 Nov., 1968 [26 Jan., 1968], No. 56370/68. Heading H4P. In a digital system comprising a central station and a number of remote terminal units, the terminals are all connected to a single modem which passes signals over a line to or from the central station. For simplex transmission over line L the modem is as at M2, Fig. 2a (part shown). When a signal is receved from the central station it passes via gate 40 and hybrid 44 to demodulator Dem. 2 which generates a "carrier detected" signal on line 9<SP>1</SP> 2  which passes via line 9<SP>11</SP> 2  to each terminal unit. Subsequently an address signal is received from the central station, this passing via line 4 2  to all the terminals. The addressed terminal responds by blocking gate 43 by a signal on line 24 2  to prevent further reception of data, and by enabling modulator Mod. 2 and blocking gate 45 by a signal on line 5 2 . When the modulator has reached its correct operating conditions it passes a signal over line 6 2  to the addressed terminal, and if the modem is ready to operate it passes a signal over line 7 2 . When the addressed terminal detects both these signals it transmits to the central station a signal indicating whether or not it is available for communication. In the case of a two way simplex system gates 43, 45 are omitted.

Abstract: 1,190,750. Moulding-machines; patterns; moulds. SIMPLEX ELECTRIC CO. Ltd. 27 Dec., 1967 [24 Dec., 1966], No. 57842/66. Heading B3F. To make a mould-part with annular cavities, e.g. for casting coupling sleeves for electric conduits, sand 22 or similar material is fed into a space formed by two plates 9, 10 and by a channel (not shown) in which they are guided (as in Specification 848,604); tubular patterns 11, for forming the cavities, extend through the (stripper) plate 10 from a back plate 15 on which they are mounted. The plate 10 may be moved towards the plate 15 as a result of sand pressure when filling. After moulding, the back plate 15 is moved, possibly manually or by springs 24 or by an hydraulic piston unit, to the position shown in Fig. 2 so that the tubes 11 are partly withdrawn from the annular cavities. Bushes 17, slidable in the tubes, remain contacting the ends of the sand plugs 23 surrounded by the annular cavities. The bores 20 of the bushes 17 act as air vents and are closed by gratings 21 to retain sand. Finally the stripper plate combination 10, 15 is withdrawn to move the tubes 11 (which may taper internally) completely from the moulded sand 22. Members 18 engaging in slots in the tubes 11 and in their bushes 17 retain the bushes against the stripper plate 10 and also prevent their rotation if the moulding- box is vibrated. The slots 19 in the tubes 11 extend along the tubes to allow of their withdrawal from the sand (possibly completely) by the movement of the back plate 15. As shown in Fig. 3, the moulding space 30 is charged with sand from a hopper 33 assisted by compressed air. When a top gate is closed, pressure applied to a piston 36 compresses both the sand and the springs of the stripper plate combination 31. Then pressure behind a piston 37 causes it to move forward together with a frame 41 on which the double plate 31 is pivoted at 42. The partial and finally complete stripping then occurs and the double plate 31 is swung up to allow piston 36 to expel the mould part 35 along a guide 34. The machine parts are returned to position and the process repeated to form a succession of parts 35 which when juxtaposed close the cavities and these can be filled with metal from above.
