Title: Fluid pressure actuator
Inventor: YOUNG TERRY G
IPC: F16K31/126
Filed: 1984-09-24
Abstract: A fluid pressure actuator having a pair of diaphragms 61, 63 on a single actuator rod assembly. The actuator housing defines a pair of spaced diaphragm chambers 94, 96 and includes a spacer spool 53 which is bolted to the adjacent chamber defining members 51, 56. The rod assembly comprises aligned stem members 71, 72, 28 which are normally maintained in engagement by gravity. A single inlet 91 is provided for simultaneous delivery of pressurized fluid to the diaphragm chambers by passages 93, 95, 97 in the upper stem 71 of the rod assembly. A stem sealing means 85, 86 between the stem member 72 of the rod assembly and the member 56 for the lower diaphragm 63 is of weld-free construction and allows limited relative lateral movement of the actuator stem members 71, 72, 28 which together with their disjointed association avoids binding and galling of the actuator rod assembly and permits independent operation of the diaphragms. An adapter member 43 for connection with a device to be actuated is secured within the axial opening of a lower housing member 52. A spring 76 between the adapter 43 and a spring support plate 74 affixed to the actuator rod assembly biases the diaphragms and rod assembly in an axial direction opposed to the fluid pressure. Travel of the actuator rod assembly is controlled by a downstop member 75 mounted on the spring support plate 74. <IMAGE>

Title: Theft alarm device
Inventor: WHEELDON STEPHEN ROBERT
IPC: G08B13/04
Filed: 1986-10-03
Abstract: The alarm device, eg for a bicycle, comprises a housing having a base 11 and cover 12. The alarm device is secured to a bicycle by a bracket, not shown, secured to cover 12. Inside the base 11, there are connected in series a pair of batteries 36,37, a movement detector, and a buzzer 30. The movement detector comprises a ferro-magnetic contact 47 connected to one end of battery 37 and a finger 48, the free end of which carries a magnet 51. The cover 12 can be secured in a closed position by a latch member 20 operated by a locking mechanism. In the position shown in the drawings, the latch member 20 has bar which prevents the finger 48 from vibrating. However, upon rotating latch member 20 through 90 DEG , the finger 48 is free to vibrate. If the alarm device is now subjected to abrupt movement, finger 48 will vibrate and the attraction between magnet 51 and contact 47 will result in finger 48 being held in engagement with contact 47 thereby energizing buzzer 30 and providing a warning signal. The circuit can also be closed by a push-button switch 55, which may be mounted on the handle bar of the cycle, and which permits the alarm device to be used as a conventional buzzer during authorised use of the cycle. <IMAGE>

Patent GB-889817-A (GB)
IPC: H01H47/02
Abstract: 889,817. Relay circuits. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Nov. 10, 1960 [Nov. 26, 1959], No. 40235/59. Class 40 (4). The operating and release times of relay R are governed by a shunt condenser C which charges through resistance R1 and discharges through resistance R2. As shown, with R normally operated, when relay P energizes in response to impulses, e.g. dialling impulses, assuming that R1 has a high value and R2 a low value, R releases at the first impulse and remains released until the end of the train. Alternatively, if contact p is normally in the alternate position so that R is unoperated, it may be arranged that R operates at the first impulse and remains operated throughout the train by giving R1 a low value and R2 a high value.
