Title: Improvements relating to push button electric switches
IPC: H01H3/20
Filed: 1951-03-14
Abstract: 678,132. Press-button retractive switches. DOWTY EQUIPMENT, Ltd., and SNELL, M. S. March 14, 1951. No. 6114/51. Class 38 (v). A switch, suitable for controlling the retraction of the undercarriage of an aircraft, may be locked for preventing normal operation and has means whereby it may be operated in an emergency despite the locking action. The push-button 11 comprises two parts 15, 16 carrying contacts 12 co-operating with fixed contacts 13, the inner face of the part 15 bearing on the upper end of a rod 22 having a cylindrical extension 23 slidable on a fixed pin 24. The switch is locked "off", as shown in Fig. 1, when a detent 26 engages a groove 25 in the pin 24 beneath the extension 23, downward movement of which is thus prevented. The switch is unlocked by energization of an electromagnet 27 which retracts the detent 26. In order to operate the switch in an emergency if the detent is operative, the part 15 is rotated through 90 degrees so that a bore 28 therein registers with the rod 22, it then being possible to depress the push-button to close the contacts. On return, of the push-button to its outer position by a spring or other means (not shown), frictional engagement between the bore 28 and rod 22 moves the latter out with the button to prevent return rotation of the button by a spring 18 until a pin is inserted in a hole 29 to push the rod 22 down again. A rubber diaphragm 30 prevents the entry of moisture or foreign matter.

Abstract: 448,357. Controlling shock-absorbers. ALVIS CAR & ENGINEERING CO., Ltd., and CLARKE, G. T. SMITH-, Holyhead Road, Coventry. Feb. 26, 1935, No. 6123. [Class 108 (iii)] A motor-vehicle friction-type shock-absorber is adjustable by means of a hydraulic connection to a diaphragm or plunger positioned responsively to the speed of the vehicle by a liquid pump. As shown in Figs. 1, 2 an oilpump 11 driven from the gear-box forces oil against a spring-pressed plunger 14 which in turn forces a different fluid through a pipe 25 to flexible bags 26 interposed between a permanently-operative friction shoe 27 and a sliding shoe 27a in a drum 28. Alternatively the oil pressure may act axially on the plates of a multi-plate shock-absorber. In another construction the plunger 14 is adapted to compress a flexible liquid-containing bag communicating with the pipe 25. In each case a manual control valve 22 as described in Specification 447,562 may be provided for modifying the effect of the pump. This valve may serve as a relief valve for the pump or there may be an independent relief valve or a small leak.

Filed: 1962-02-20
Abstract: 990, 688. Weighing apparatus. BLACK PRODUCTS CO. Feb. 20,1962, No. 6586/62. Heading G1W. A bag filling machine comprises a scale mechanism which includes a beam 25 from which spout assembly 34 is suspended by being mounted on a fulcrum parallel to the axis of the spout 15 and feeding mechanism communicating with the spout and including cut-off means 16 actuated by the movement of the beam. The bag 20 is slipped over the spout 15, Fig. 1, the inlet of which communicates with a conditioning chamber 12 through a flexible tube 14, to which the means 16, which is a pinch valve, is applied. Material is caused to flow from the chamber 12, through the tube 14, into the bag 20 when a diffuser pad 13 is energized by means of an air supply 18. The beam 25, shown separately in Fig. 10, is fulcrummed, Fig. 4, on conical hearing points 22 which are mounted at the tops of the vertical limbs of a U-shaped member 21, shown separately in Fig. 11. Each hearing point 22 may comprise a 60 degrees cone for which a seating may be adapted in the form of a 90 degrees conical recess in a hearing pad. The spout assembly 34, shown separately in Fig. 9, is suspended from the beam 25 at two spaced points, for which purpose it has two lugs 35, 36 in which are hearing pads for co-operation with hearing points 37, 38 on the front and rear members 26, 27 of the beam 25. The spout assembly includes a mounting plate 40 in which is an opening 41 for the spout 15, the axis of which is therefore parallel to the straight line distance between the hearing points 22, i.e. to the fulcrum of the beam. To prevent the spout from tipping forwards, the assembly 34 has counterweights 42 attached to its rear. In a modification the spout assembly is supported only from the hearing point 37 and is prevented from tilting by a strut. Conical hearing points 46 engage a bracket 45 which carries the balance weight 44 and has hearing pads for the purpose. An auxiliary scale beam 55, having a weight 56 slidable thereon, may be mounted on the front member 26 of the beam 25, so providing tare adjustment when bags are changed. To limit the movement of the beam a yoke 52 embraces the side bar 28 of the beam, screws providing travel adjustment. In operation, a weight 44 is attached, of a magnetude required to balance the amount of material to the bagged. The valve 16 is opened and the air supply 18 is started. The beam 25 turns, as the bag is filled, until its side has 28 leaves contact with the plunge of a microswitch 50 which breaks a control circuit and thus causes the valve 16 to cut off the feed. Specification 881,776 is referred to.
