Title: Improvements in or relating to motor vehicle shock absorbers
IPC: F16F9/34
Filed: 1954-07-09
Abstract: 753,092. Hydraulic shock-absorbers. FORD MOTOR CO., Ltd. July 9, 1954 [July 21, 1953], No. 20176/54. Class 108 (3). A direct-acting shock-absorber for a motor vehicle, comprises a piston C operable in a cylinder A having a fluid escape passage 46 adjacent which is a resilient member 81 engageable by the piston C to close the passage 46 and trap a body of fluid in the cylinder. The piston has peripheral liquid-flow grooves 43. The passage 46 is controlled by a spring- loaded valve 44 and leads to a recuperation chamber B. The upper end of the passage 46 opens into a countersunk portion 87 defined by a peripheral rib 86. An inclined further rib 88, surrounds the passage 46. In operation, on compression, the lower face of the piston engages the upper face of the member 81 as shown, and further piston movement results in the rib 88 sealing off the passage 46. Further movement still, results in a rib 83 at the upper end of the member 81 closing the lower ends of the piston grooves 43. The rib 88 may be dispensed with, in which case, the member 81 is distorted so that the base of the countersunk portion 87 closes off the passage 46. In a further modification, the axial length of the rib 83 is greater, so that the grooves 43 are closed before the passage 46. The rib 83 may, however, be dispensed with. The piston C may have a rebound valve (not shown) controlled by a temperature-responsive device as described in Specification 753,049. Flow of oil through the rebound valve takes place through a series of radial passages in the piston-rod.

Title: Photographic cameras
IPC: G03B9/58
Filed: 1975-05-15
Abstract: 1485530 Camera exposure control circuits SEIKO KOKI K K 15 May 1975 [16 May 1974] 20613/75 Heading G2A A camera has a brightness/time conversion circuit 4 for generating a single pulse whose width depends on subject brightness, means 3 for generating reference frequency pulses which are memorized by a counter 7 during the duration of the single pulse, means for controlling shutter time in accordance with the memorized count and means for varying the width of the single pulse to take account of exposure factors other than subject brightness e.g. film speed, diaphragm aperture. As shown circuit 4 comprises a photo-conductor 4-2 an integrating capacitor 4-3 and a switching circuit 4-4, the width of a single pulse being varied either by connecting one or more resistors 4-10, 4-11 to circuit 4-4 to alter its switching point or by connecting one or more additional capacitors (not shown), in parallel with capacitor 4-3. A switch contact 8-21A, Fig. 3(A), is movable across contacts 8-22A and 8-23A to connect resistors 4-10 and 4-11 in circuit and else moves across contacts 8-2A, 8-3A ... to earth a corresponding terminal 8-1, 8-2 ..., Fig. 2, which routes the pulses from generator 3 direct to a selected stage of counter 7 or via a selected stage of a frequency divider 6. Thus for ASA100, F5À6, contact 8-21A is moved to position (a) in which 4-10 and 4-11 are out of circuit and in which terminal 8-5 is earthed. If subject brightness is such as to generate 32 pulses these will be routed to the first stage 7-1 of counter 7 by a switching element 8-15 connected to terminal 8-5. For ASA80, F5À6, contact 8-21A is moved to position (e) in which 4-10 and 4-11 are in circuit, causing the number of pulses to be reduced to 20, and in which terminal 8-4 is earthed causing the pulses to be routed through a switching element 8-14 direct to the second stage of the counter - providing an effective count of 40.  Terminals 8-1 to 8-9 can also be used to preset exposure times manually. An indicator circuit Fig. 4 (not shown), has LED's for indicating shutter time, over and under-exposure and "overflow".

Abstract: 857,432. Nuclear reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. June 24, 1959 [July 8, 1958], No. 21808/58. Class 39(4). Apparatus for shutting down a nuclear reactor comprises a tube removably accommodatable in the reactor core, means for charging a multiplicity of neutron absorbing balls into the upper end of the tube on operation of the apparatus for shut down, and releasable closure means for the lower end of the tube, the closure means being normally closed for retention of the balls after they have been charged into the tube and being opened after withdrawal of the tube from the reactor core for recovery of the balls. In Fig. 1 a magazine assembly 9 is positioned above a channel 1 in the moderator structure of a nuclear reactor and comprises a container 13 having deflector shoots 14 leading to form outlet pipes of rectangular cross-section which have outlets 16 into a central tube running through the assembly.

Title: Improvements in and relating to vibration measuring instruments
Inventor: LAKE EDWIN WALTER
IPC: G01H1/10
Filed: 1957-07-12
Abstract: 840,224. Electrical measuring systems. NATIONAL RESEARCH DEVELOPMENT CORPORATION. June 25, 1958 [July 12, 1957], No. 22105/57. Class 40 (1). An instrument for measuring torsional vibrations of a shaft comprises two members lightly coupled together, one member being adapted for rigid connection to the shaft, the other member being a free mass and means for varying a magnetic field by the relative movement of the members so as to generate in a coil an electrical signal dependent on the frequency and amplitude of the vibrations of the shaft. As shown, a non-magnetic shaft 6 may be attached to the tested shaft by means of a flange 7. The shaft 6 is journalled in ballbearings 12, 18 at the ends of a casing 32. A free mass 2 is carried by ball-bearings 14 on the shaft 6 and is lightly coupled to a spider 13, fixed to the shaft 6, by springs 26 attached to a pin 27, so that the free mass rotates at a constant speed whilst the shaft 6 follows torsional vibrations of the tested shaft. Friction dampers 29 bear on the end of the free mass 2. Also carried by the shaft 6 is a steel sleeve 16 having teeth 16a which are located within a set of teeth 23a formed on the inside of a ring 22 attached to the free mass 2. A cylindrical permanent magnet 3 forms part of the free mass 2. A variable reluctance magnetic circuit is thus formed about a fixed coil 5 via the variable air gap between teeth 16a and 23a, the steel sleeve 16, the end 35 and the steel casing 32. The amplitude of vibration is measured by means of a meter or wave analyser, an integrating circuit being interposed to render the output independent of vibration frequency.
