Title: Improvements in or relating to dashpots
IPC: H01H85/36
Filed: 1944-07-03
Abstract: 583,955. Electrically-released switches. WEST & CO., Ltd., A., and BREEZE, V. L. July 3, 1944, No. 12665. [Class 38 (v)] [Also in Groups XXXII and XXXVI] Relates to a liquid or air dashpot comprising a plunger (or piston) moving in a cylinder, part of the movement of the plunger being free while, over another part of its movement, the plunger engages in a reduced portion or throat of the cylinder. According to the invention, the plunger is provided with one or more piston rings which effect the engagement with the reduced portion of the cylinder. A dashpot fuse is shown of the type in which current flows from a terminal 1 at the upper end of an insulating tubular container 2 through a fusible element 3 and in series through two conducting telescopic parts 4, 5 to a terminal 6 at the lower end of the container. The upper part 4 is normally held in the position shown in Fig. 1 by the fusible element 3 and when this is fused by excess current, the part 4 is pulled rapidly downwardly through an arc-extinguishing liquid 8 in the container until an enlargement on a cylindrical plunger 9, of insulating material, on the part 4 engages a reduced throat 10 in the container producing a dashpot action which slows the movement of the part 4 until the plunger leaves the throat. Thereafter, the part 4 moves rapidly until the end of its travel when auxiliary contact elements 11 engage the throat 10 which is constituted by conducting material and is connected by a second fuse (not shown) to the line to which the terminal is connected. The container shown consists of two insulating portions 2a, 2b joined by a metal throat 10. In a fuse of the type above described, the enlargement on the plunger 9 is constituted by a number of piston rings 12 of insulating material, e.g., synthetic resin, mounted in circumferential grooves in the plunger, and in order to cause the rings to make correct initial engagement with the flared or bevelled end 10a of the throat, i.e., without jamming, each ring is formed with a small axial gap 12a and is coned eccentrically on its lower face. Hence, when the ring first engages the bevelled end 10a of the throat, it is first pushed laterally so that its point opposite the gap 12a is pressed against the bottom of its groove in the plunger and on further axial movement, the bevelled end of the throat causes partial closure of the gap 12a and correct engagement of the ring in the throat. The gap 12a is left slightly open to allow the liquid 8 to flow through it and the movement of the plunger to continue when the ring fully engages the throat. A leading ring 13 of smaller diameter than the rings 12 may also be mounted on the plunger to help centre the plunger relatively to the throat before the first ring 12 becomes operative.

Abstract: 950,880. Controlling aircraft. SHORT BROS. & HARLAND Ltd. March 19, 1962 [April 10, 1961], No. 12874/61. Heading B7G. [Also in Division G3] Movement of a pilot's control 13 is transmitted to an aircraft control surface 20 by three separate but identical channels 1, 2 and 3, each including a potentiometer 12 which generates an electric signal that varies in amplitude in accordance with variations in the position of the control 13; these electrical signals are applied to a high-gain amplifier 14, the output from which is led to a torque motor 15, connected by a shaft 16 to a spool valve 17 controlling an hydraulic servomotor 18 having an output shaft 19 coupled to mechanism for operating the surface 20. A pick-off device 21, which is connected by a shaft 22 to the shaft 16, generates an electric signal representative of the position of the latter, this position signal being fed to an amplifier 23, the output from which is applied to a signal comparison unit of the fault detection system described in Specification 918,144 which is common to all three channels. This amplified signal also drives an integrating electric motor 24, the position of the output shaft 25 of which represents the first time integral of the position signal; the shaft 25 is coupled via reduction bearing 26 and a shaft 27 to the wiper 28 of a potentiometer 29 to produce an electrical signal proportional to integral of the position signal, which is fed back to the amplifier 14 so increasing the amount of negative feedback at low frequencies. The shaft 27 also drives the disc 30 of a limit switch controlling a channel alarm circuit 35 which is closed to indicate a faulty channel when the angular movement of shaft 27 exceeds a given value. The output of the torque motor 15 is fed back to the amplifier 14 via the pick-off device 21 which generates a further position signal for this purpose. The shaft 19 also drives the wiper 37 of a potentiometer 38, the electrical signal from which is also fed back to the amplifier 14. Specification 918,144 is referred to.
