Filed: 1943-09-22
Abstract: 559,476. Photographic cameras. WHEELWRIGHT, B. Sept. 22, 1943, No. 15506. [Class 98 (i)] In a camera a body section containing the image-receiving surface is so mounted that this surface is automatically maintained vertical when other parts of the camera are tilted, and is so interconnected with a lens-carrying section that when the optical axis of the lens is adjusted to any desired angle of elevation or depression either the body or the lens-carrying section is automatically moved so as to maintain the central or principal point of the image area on the optical axis. The camera shown comprises a body or focal-plane section A, a front section B, carrying the lens, and a base C mounted on a stand D. The base is formed of superposed members c<SP>3</SP>, c<SP>4</SP> hinged together at their front edges by a hinge c<SP>5</SP>. The upper member c<SP>3</SP> carries a pair of arms c' between which is horizontally pivoted a ring a<SP>5</SP> carrying a part-splined member a<SP>2</SP> to the rear edge of which a holder a<SP>1</SP> for the sensitive material is connected by a ballrace a<SP>4</SP>, so that the holder d adopts a vertical position under the action of gravity in whatever direction the camera is tilted. The front is carried by arms c<SP>2</SP> secured to the lower member c<SP>4</SP> of the base and includes a vertically-slidable panel b<SP>1</SP> carrying the lens and a part-splined member b<SP>5</SP> connected by bellows b<SP>6</SP> to the member a<SP>2</SP>. The lower base-board member c<SP>4</SP> is pivoted on depending brackets f formed as gear segments, which are pivoted to a member d' rotatably mounted in the top of the stand D. Pivoted about the same axis are two brackets h<SP>1</SP>, formed as gear segments of smaller diameter than the brackets f and carrying a bar h which is accommodated in a slot in the base member c<SP>4</SP>. When the camera is tilted downwardly as shown, by rotation of a shaft i carrying gears engaging the gear segments f, h', the bar h is turned through a greater angle than the member c<SP>4</SP> so that it lifts the upper base member c<SP>3</SP> and raises the body A. When the camera is tilted upwardly, the front of the bar h engages a downward projection b<SP>3</SP> of the panel b' carrying the lens, and raises it. In both cases the movements are such as to maintain the coincidence of the optical axis with the centre of the image area.

Title: Improvements in or relating to switch control devices for dynamically braked, electrically driven machines
IPC: H02K7/10
Filed: 1948-06-09
Abstract: 639,817. Control of motors; mechanical switches. MASON, J. A., and MOLINS MACHINE CO., Ltd. June 9, 1948, No. 15595. [Classes 38 (iii) and 38 (v)] [Also in Group XXIV] A switch control device, for use with dynamically-braked, electrically-driven machines comprising variable speed gearing for driving the machine, has means for adjusting the switch relatively to the cam or the like which operates it so as to vary the instant of disengagement of the contacts and initiation of dynamic braking in accordance with variations in the adjustment of the variable speed gearing. In a packet-wrapping machine the packets are moved by pusher-pieces 1 on a conveyer 2 which is driven by an electric motor 3. The motor is controlled by means of a timing- switch 4 which is adapted to initiate dynamic braking and to stop the machine in a predetermined position, as described in Specification 628,299. The motor drives pulleys 15 and 16, the latter being geared to the main shaft 21 of the conveyer. The member 15 comprises two separate parts (see Group XXIV) which are relatively movable to alter the effective diameter of the pulley, this adjustment being effected by means of a worm 29 coupled by flexible cable 30 to a movable knob or handle 31. The worm-shaft has a threaded portion co-operating with a nut which is coupled through bell-crank 34 and link 37 to a lever 12 which is fixed to a spindle of the switch 4. The switch comprises contacts 7, 8, which are mounted on switch body 9 and which co-operate with a plunger 6 coacting with a cam 5 driven from shaft 21. When the member 31 is moved to alter the speed of the machine, the switch body is correspondingly adjusted relatively to the cam 5 and the moment at which contacts 7, 8 are opened is determined by the speed at which the machine is running. The lever 12 may be in the form of a quadrant to allow for adjustment to compensate for different operating conditions. A belt 25 is held taut during adjustment of the variable speed drive by means of a spring 39 and quadrant 20. The pulley 16 may be slidable in splines in order to align the belt correctly.

Abstract: 1337233 Locks EASTERN CO 6 April 1972 [9 April 1971] 15824/72 Heading E2A An electronic lock system comprises a key 10 having a data store 12 which may be coupled to the lock by contacts, the lock including a master code store 24 which is compared at 22 with that in the key to operate a logic circuit 26 to give different responses to agreement and disagreement of the codes in the key and. the lock. The key memory is of shiftregister type powered by battery 14. Data from the memory 12 is read out under the control of clock pulses at CLK to the data gate 18 which returns them to the key memory and also to a memory 20 in the lock. A comparator 22 compares the signal from memory 20 with that from master code generator 24 and feeds the result to a logic circuit 26 which can actuate suitable release means or, if the wrong key code is employed, give an alarm. The clock 28 is started by key insertion detector 32. The key shown in Fig. 2, will only emit its code when interrogated by an appropriate coded signal from the lock. Memory 34 is compared at 36 with an enabling code from the lock, identity allows read-out of memory 38 which can actuate the lock, but non-identity causes the comparator to provide an alarm signal. In a further modification (Fig. 3, not shown) additional codes acting to operate an AND gate are used. It is described (Fig. 4, not shown) how clock pulses, besides controlling the comparison of codes &c, also serves to clamp the key in the lock during interrogation and if it carries a wrong code to permanently capture it. As shown in Fig. 5, the key 80 may be plastics strip enclosing the circuitry energised by a battery at 84 and making contact at U-shaped conductors 86 in a connector 87. A micro-switch 90, 92 detects insertion of the key in the lock. The key is clamped at slot 94 by solenoid 96.

Abstract: 272,914. Kidde & Co., Inc., W., (Assignees of Freygang, W. H.). June 17, 1926, [Convention date]. Light radiations, control of apparatus by.-In a method for giving automatic warning of the presence of suspended matter in fluid, for example smoke, light is directed by the suspended matter by reflection and/or refraction upon a normally non-illuminated light sensitive element, for example a photo-electric cell, arranged in an alarm circuit. As shown in Fig. 1, smoke-laden gases are drawn from spaces to be protected by pipes 3 and pass through tubes 5 to a detection chamber 6. At one side of this chamber is a light-sensitive cell 1 in a casing 2 having a window 11. Light from a source 8 is directed through the tubes 5 by suitable lenses and mirrors, and is reflected or refracted by the suspended particles upon the cell 1, energizing the latter and operating an alarm. As shown in Fig. 6, the cell 1 is in circuit with a resistance 14, battery 13, and relay 21 through a three-electrode thermionic amplifier 16. The relay 21 is in circuit with a battery 25 and bell 24. In a modification, the light from the source 8 is concentrated to a parallel beam travelling across the path of gases issuing from a single smoke pipe. In modifications of the first arrangement, the reflected light is concentrated on the cell by a parabolic mirror, or by a lens arranged in the window of the casing 2. In another modification, several sensitive cells are provided, light from the source 8 being distributed by a lens system.
