Patent GB-1259184-A (GB)
IPC: H03F3/72
Filed: 1969-03-28
Abstract: 1,259,184. Diode gating circuits. IWATSU ELECTRIC CO. Ltd. 28 March, 1969 [2 April, 1968], No. 16303/69. Headings H3P and H3T. A gating circuit has two diodes D1, D2 in series opposition between a signal input 1 and an amplifier, and a third diode connected between their junction and a gate pulse source at 4; there being also capacitors C2, C3 between earth and the said junction and the output side of D2 respectively, and a shaping and storing circuit connecting the amplifier to the output terminal 5, from which a feedback circuit R11, R12 is taken to the diodes. The diodes are normally biased off by E.M.F. sources E1, E2, E3 and associated resistors, and are turned on by a gate pulse. The capacitor C2, with R2, attenuates leakage signals from the input 1 when the diodes are off and exhibit capacitance (e.g. C4), to avoid accumulation of such leakage signals on the capacitance C3 which stores the output of the diodes when they conduct, the value of C2 being preferably at least 300 pf. The provision of diode D3 prevents reflection of the input signal at 1 by the pulse source at 4 which would cause deterioration of the output signal especially at high frequencies. The amplifier is a F.E.T differential amplifier receiving the feedback signal at the gate of TR2, the input signal going to TR1. The diode circuitry may be duplicated (Fig. 5, not shown) to give a diode bridge arrangement.

[Also in Division G4] Apparatus for controlling the braking of a moving vehicle 15, Fig.1, so that it will stop at a desired distance D comprises a tachometer 15 for measuring its instantaneous speed V, whose output signals are fed (a) to a differentiating circuit 26 to determine the instantaneous deceleration, and (b) to a computing network for calculating -V<SP>2</SP>/2D, i.e. the deceleration required for the vehicle to stop at the distance D. These two values of deceleration are compared at 28 and any difference is eliminated by using the difference signal to control the braking device 31.

Abstract: 1,264,968. Silver halide photographic material colour developing process. EASTMAN KODAK CO. Oct.2, 1969 [Oct.2, 1968], No.48558/69. Heading G2C. A method of developing a photographic material housing a support carrying at least one imagewise exposed silver halide emulsion layer containing a development inhibitor releasing coupler (i.e. a coupler which upon reaction with an oxidized primary aromatic amine colour developing agent forms a dye and releases a compound which inhibits development) comprises treating the layer with a developer solution containing a competing coupler (i.e. a coupler which couples with the oxidized aromatic amine developer to form a coloured or colourless compound which leaves no permanent colour in the processed layer) and an aromatic amine colour developing agent which forms a dye on oxidative coupling with the coupler. The developer solution preferably contains 0À05 to 20g per litre of the competing coupler. Many examples of competing couplers are listed. The developer solution may contain an auxiliary developing agent e.g. 1-phenyl-3-pyrazolidone, 1-phenyl- 4, 4-dimethyl-3-pyrazolidone or an amino phenol developing agent. The developing solution may contain a silver halide solvent e.g. an alkali metal thiocyanate. The DIR coupler may have a monothio group in its coupling position in which case the coupling -off group is a mercaptan which inhibits development and the dye formed by coupling is diffusible. By this process fine line copy is recorded satisfactorily and acceptable continuous tone images may be produced.

Abstract: 1317567 Fuel injection pumps C A V Ltd 21 Sept 1970 [3 Oct 1969] 48628/69 Heading F1A In a rotary distributor fuel injection pump in which the pumping space between the inwardly acting pistons 12 is filled with fuel displaced from a bore 16 by a shuttle 17, the starting position of the shuttle, and thus the quantity displaced, is determined by an axially and rotatably adjustable eccentric stop 56. The stop 56, Fig.2, is in the form of a tapered portion of a piston 50, the portion being eccentric to the axis of the piston. The initial position of the stop is adjusted by rotating a plug 54 having a non-circular projection 55 engaged in a complementary recess in the piston 50. During operation, fuel from a feed pump 22 moves the piston 50 against springs 52, rotation of the piston being prevented by the projection 55. The filling of the bore 16 occurs during inward pumping movement of the pistons 12. At this time an inlet port 20 to the bore 16 communicates through a longitudinal groove 18 with a circumferential groove 19 in permanent communication with the feed pump 22. The fuel displaced by the consequent outward movement of the shuttle 17 flows through passages 23, 24 and grooves 25 aligned with spill passages 26a. Subsequently the fuel in the bore 16 is expelled through a passage 15 to the pumping space by connection of one of the grooves 25 to an inlet 26. During the inward stroke of the pistons 12 fuel is delivered to whichever of a plurality of outlets 14 is aligned with a radial passage 13.

The missile is finally brought to the target by the head 10 which is activated at a point 11 along the missile trajectory 5. The missile is detonated by a proximity fuze. The azimuthal bearing is transmitted directly to the gyroscopic system by a synchrometer 4 or by the rotation of the missile within a launching tube 13, Fig. 2. The launching tube is provided with a closure 14 and a reticulate firing tube 16 formed with guide surfaces 7 and 18 for the missile.

Abstract: 1329236 Container traffic ADROLIC ENG CO Ltd 17 Sept 1970 [22 Sept 1969] 46491/69 Heading B8Q A device for transporting containers comprises a platform, Fig. 4, having retractable front 13 and rear 16 legs on which a container (not shown) is supported prior to engagement of the platform with a vehicle chassis, Fig. 2, each front leg being connected by pivotable interconnected links 14, 14a to the platform frame and each back leg similarly connected by links 17, 17a. To mount the platform on a vehicle chassis the chassis is backed below the forward end of the platform such that rollers 12 on the platform engage and run up along ramps (28a), Fig. 1 (not shown), thus raising the legs 13 off the ground and trip ramps 32b on either side of the chassis actuate pins 14b at the common linkage of 14, 14a thus permitting the legs 13 to fold upwardly and rearwardly and run along guides 33 on the chassis until the rollers 12 abut chassis stops 31. To raise the rear platform legs 16 hydraulic ram 42 is actuated to move a crosshead 36 rearwardly which causes pivotally connected toggle links (35), (37) of two toggles 34 to straighten upwardly thus raising the rear end of the chassis rails 27 (shown in dotted lines in Fig. 1 (not shown)), thereby raising the platform rear legs off the ground and also imparting a rearward movement to a slide 41 which movement is transmitted by a crossbar 41a to a sliding carriage 20 on the platform on which are mounted two pulleys at one end one to each of the legs 16 and engaging with the common pivots of the links 17, 17a, and connected at the other end to the platform frame. Rearward movement of the carriage 20 tensions both the cables 19 thus collapsing each of the pair of links 17, 17a thus pulling the rear legs inwardly while a hook (39), Fig. 1 (not shown), of the toggle link 37 lockingly engages a bar 43 of the platform and continued movement of the crosshead 36 results in the rails 27 and platform being lowered to rest on the chassis girders (22), Fig. 1 (not shown). Reversal of the above procedure separates the vehicle chassis from the platform which is left supported on its legs.
