Patent GB-1302385-A (GB)
IPC: G03B15/04
Filed: 1970-02-26
Abstract: 1302385 Photographic cameras EASTMAN KODAK CO 26 Feb 1970 [27 Feb 1969] 9248/70 Heading G2A In a photographic camera having a rotatable flash-cube socket 19, indexing thereof is effected as a result of rotation of a film winding member 17 via a drive lever 18, which lever is disconnected from the winding member 17 when the socket has been rotated through 90 degrees. The mechanism is shown in position after an exposure is made, but before film winding is effected, a shutter operating member 15 being retained in its depressed position by a double exposure prevention device (not shown) which also co-operates with film winding and metering mechanism. Upon anti-clockwise (as seen) rotation of the member 17, a cam lobe 22 thereof encounters and pivots a cam follower nose 23 of the lever 18 clockwise, so that a pawl-tooth 26 of the lever 18 engages the vertical shoulder (41) Figs.3, 5 (not shown) of an adjacent socket ratchet tooth (37) and rotates that anti-clockwise until stopped by a spring (34). Simultaneously, a hooked end (45) of a tongue 46 of a resilient latch member 42 carried on the lever 18 rides up onto raised surface 49 and eventually drops down past the forward edge 52 of the surface 49, thereby latching the lever 18 out of engagement with the member 17 Fig.4 (not shown). When sufficient film has been wound on, the metering mechanism stops further rotation of the member 17 and allows the shutter operating member 15 to rise. This causes an ear 57 of a latch release member 53 to displace the hook (45) to the right and into alignment with a channel 58. Then the drive lever 18 is pivoted back to the position shown by a spring 27, while the tongue 46 travels along the channel 58, until the tooth 26 is behind the next ratchet tooth, and the latch member 42 is restored to the position shown by abutting a wall 44. If, on this return movement, the nose 23 contacts a lobe 22, the lever 18 is stopped, and is only free to return to the position shown, at the beginning of the next film winding action, which action subsequently causes socket indexing as described.

Filed: 1925-04-08
Abstract: 245,713. Jacobs, F. G. Jan. 12, 1925, [Convention date]. Clutches, friction; shaft couplings.-In slipping couplings of the kind in which centrifugal blocks carried by the driven shaft are spring-pressed into engagement with a driving-drum, the blocks are radially guided, so that the maximum torque transmissible to the driven member at any speed thereof is dependent solely on the spring load and centrifugal force acting on the blocks. A hub 2, Fig. 1, on the driven shaft carries friction blocks 3 pressed radially by their own elasticity or by springs 4 into contact with a driving-drum 1, the pressure being augmented, when the driven shaft rotates, by centrifugal force produced by the blocks 3 or by separate masses (not shown). The driven member may carry a flywheel which, during overload, delivers energy to the driven parts. The springs may act between the blocks 3 and hub 2. For use with internal-combustion engines, single-phase electromotors, and other motors having a low starting effort, the clutch described, shown at 6, Fig. 3, may be combined with an ordinary centrifugal clutch 5 carried by a driving-member 9. Specification 107,785 is referred to.

Title: Process for improving titanium dioxide pigments
Inventor: HUGHES WILLIAM
IPC: C01G23/07
Filed: 1958-03-24
Abstract: <PICT:0867479/III/1> Titanium dioxide pigments may be modified by reacting the titanium dioxide whilst in gaseous suspension with an anhydrous aluminium halide, thereby replacing some of the titanium dioxide with aluminium oxide, and then reacting the titanium tetrahalide vapour formed with water vapour in the presence of the titanium oxide-aluminium oxide mixture, to deposit titanium oxide on the particles of the mixture.  The reaction with the aluminium halide is preferably carried out at 250-750 DEG C., and the water vapour reaction at 180-600 DEG C.  The titanium dioxide pigment to be modified may be that obtained by calcining and milling hydrated oxide precipitated from acid solution, but is preferably that prepared by the vapour phase oxidation of titanium tetrachloride. Preferably the amount of aluminium halide employed is between 0.1 and 10% by weight of the titanium dioxide, calculated as aluminium oxide, and may be introduced as a solid, solution or vapour, for example that generated from an aluminium halide-alkali metal halide melt or that obtained by passing chlorine over heated aluminium or heated aluminium and carbon.  Alternatively, the halide may be formed in situ by introducing a fine aluminium powder which reacts with gaseous halogens in the gaseous suspension of titanium dioxide.  In the Figure, titanium tetrachloride and oxygen are supplied via nozzles 4 and 6, to form titanium dioxide in zone 1.  Aluminium chloride vapour is supplied via line 11, fitted with radial ports 14, and reacts with the titanium dioxide.  Water vapour is introduced via line 13, fitted with radial ports 15.  The reaction product passes via lines 17 and 18 to collecting means.

Abstract: 1287822 Fuel injection systems ROBERT BOSCH GmbH 27 Feb 1970 [28 Feb 1969] 9558/70 Heading G1N [Also in Division F1] In a fuel injection control system, the quantity of fuel injected is determined by the position of a fuel injection pump setting member which is regulated by the position of a rotatable magnet. The position of the magnet 10 is determined by the value of a signal applied to coils 11, 12 surrounding the magnet, the signal being derived from an electronic control circuit in dependence upon the speed of the engine determined by a generator 30, 31, 32, other engine operating parameters, e.g. accelerator pedal position, intake pressure, engine temperature, atmospheric pressure, determined by transducers 44, and the feedback signal of the position of the magnet determined by a transducer 35-39. Rotation of the magnet causes a slider 19 to move on the pump delivery piston 20 which is rotated and reciprocated during engine rotation. Thus, the bores 21 in the piston 20 are opened at an earlier or later instant to vary the delivery quantity. The magnet 10, coils 11, 12, position transducer 35-39, and tachometer 30-32 are mounted within the pump housing, Figs.2 and 3 (not shown), the housing being closed by a cover having on its inner side a printed circuit, Fig.4 (not shown) for making connection with the various components within the housing.

Abstract: 1,256,361. Voltage measurement. J.H. FERMOR. May 28, 1969 [Feb. 28, 1968], No.9683/68. Heading G1U. An electrometer system for measuring a unidirectional input voltage incorporates two series pairs of capacitors 9, 10; 11, 12 connected across one another and also across an impedance path 15, 16 or a switchable path (15<SP>1</SP>, 16<SP>1</SP> Fig.4 (not shown)). The input is applied between the common junctions of the capacitors of the two series pairs of capacitors. The capacitors in each pair are varied in antiphase and an alternating signal appears across the impedance or switch path whose amplitude represents the input unidrectional voltage. This alternating signal may be suitable amplified at 19 and indicated at 20. If switches are used in place of the resistors 15, 16 they are operated in synchronism with the capacitor varying control 14 to be open as the capacitors are varied through a cycle, and then closed through a period during which the capacitance values are kept steady, the frequency of the periodic variation of the capacitors being an integral multiple of half the operating frequency of the switch. Each capacitance has the same mean value, and the capacitances of each pair are varied such that the sum of their capacitances remains constant. Thus no feedback occurs into the source of the unidirectional voltages. The centre of symmetry of the resistance or switch path is earthed.
