Title: Improvements in and relating to double-throw electric switches
IPC: H01H23/00
Filed: 1947-05-29
Abstract: 632,715. Snap-action switches. O'SHEI, W. E. May 29, 1947, No. 14346. [Class 38 (v)] A double-throw vehicle traffic indicator switch comprises an operating arm 12 having extensions 11 which receive by means of hexagonal apertures a hexagonal sleeve 7 rotatable on a spindle 8. Mounted for rotation with the sleeve 7 are insulating members 1 and a metal plate 2 positioned between them and supported on an insulating part 10. Spring contacts 4, 4a normally engage projections 3, 3a on the members 1 and hold the arm 12 in the central " off " position. Movement of the arm 12 to one side rotates the plate 2 to bridge a contact 4 or 4a and a spring plunger contact 13, and the respective projection 3 or 3a locates the switch in this position by engaging the V-shaped end of its associated spring contact 4 or 4a. The arm 12 is operated by a handle 21 having a translucent cover 22 and enclosing a bulb 20, the arrangement being as disclosed in Specification 624,508. A circuit is established to illuminate the bulb, when the switch is in either of its operative positions, by means of a spring 26 pressing between the plate 2 and a metal disc 25 connected to the bulb through an insulated conductor 27, the return being through the earthed casing 15. In an alternative construction, the spindle 8 may be operated by a rotary handle attached to it.

Title: Jacking devices
IPC: E21D21/00
Filed: 1971-05-12
Abstract: 1331805 Jacks D N FORBES 12 May 1971 [22 May 1970] 14435/71 Heading B8J [Also in Division E1] A jack, Fig. 2, comprises a plunger 13 formed with opposed conical recesses 24 formed at the ends of a pilot bore 22. The plunger 13 is surrounded by a stirrup 26 having a crossmember 28 with a central threaded bore 30 receiving a bolt 32 having a conical point complemental to and engaging one recess 24. Opposite the bolt 32 a conical anvil 36 is fixed in the stirrup 26 engaging the other recess 24. In use the jack is positioned between opposed surfaces 11, 12 with the bolt 32 and anvil 36 partially engaged in the recesses 24. Turning the bolt 32 to bring its point nearer the anvil 36 causes a wedge action resulting in the stirrup 26 sliding to the right on the surface 11 as the plunger 13 moves upwards. Fig. 7 shows, in section, a modification wherein the wedging action is produced by a wedge 50 acting between a cross-piece 45 on a stirrup 40 and a rod 48 sliding in a cross-member 44 and having a conical point similar to that of the bolt 32. The jack may be used in conjunction with a pit-prop 10, Fig. 5, which may incorporate friction yielding mechanism 17. As shown the prop may be struck by a long spanner 15 (for the jack shown in Fig. 1) or by a long-handled hammer (for the jack shown in Fig. 7). The jack may also be used to tension roof bolts (90), Fig. 10 (not shown).

Title: Hydraulic impactors
IPC: B25D9/12
Filed: 1975-04-08
Abstract: 1535927 Hydraulic impactors INDUSTRY SECRETARY OF STATE FOR 6 April 1976 [8 April 1975] 14438/75 Heading B4C  An hydraulic impactor comprises means for admitting pressurized fluid to opposing faces 11 and 6, 63 of a piston 1 to advance and retract the piston 1, and a switching device 8 which controls the admission of the fluid to the face 11 and switches the direction of movement of the piston 1 from a reverse to a forward direction at an instant dependent upon the retraction velocity of the piston 1. In the impactor a cavity 32 is always under high pressure line H whereby walls 6, 63 are always under high pressure. The device 8 can switch a duct 9 and therefore wall 11 to either high or low pressure for forward or reverse travel of the piston 1. At forward mid-way travel of piston 1 another piston 25 is subjected to high pressure due to it being connected to groove 32. The piston 25 shifts latch valve 37 and spool valve 13 toward the piston 1 opening port 15 to high pressure line H. Device 8 is switched on to connect line 9 to low pressure. During the return movement of piston 1 piston 25 retracts due to its connection to groove 29. A tapered portion 17 by now has entered a blind hole 18 of piston 1. Pressure builds up sufficiently depending upon speed of retraction of the piston 1 to retract valves 13 and 37 to low pressure line and hence to switch device 8 to connect wall 11 to high pressure line H. During impact the piston 1 has to move rearwardly a greater amount before a sufficient fluid pressure builds up in hole 18 to retract valves 13, 37 to switch valve 18 therefore utilizing as much energy, due to impact, as possible. If sufficient fluid pressure does not build up a collar 19 of hole 18 engages the portion 17 to retract it to retract the valves 13, 37.

Title: Improvements in and relating to landing gear for aircraft
IPC: B64C25/52
Filed: 1929-05-09
Abstract: 326,705. Boulton & Paul, Ltd., and North, J. D. May 9, 1929. Shock-absorbers, applications of; wheels and skids.-In skid type landing gear, the skids are attached to the frame of the aeroplane by articulated and extensible members which are so arranged that the skids during flight lie adjacent to or within the contour of the aircraft and, when desired, may assume, by extending the said extensible members, a position suitable for landing. In one form a skid A is carried by two systems of articulated members each comprising struts C, D, hinged to the aircraft and to the skid and an extensible member consisting of a piston rod E hinged to the skid at E<1> and carrying a piston E<2> slidable in a, cylinder F pivotally mounted at F<1>. Springs F<2> normally retain the pistons E<2> at the upper end of the cylinders F causing the skid to maintain the retracted position shown in Fig. 2. To bring the skid A to the landing position, Fig. 1, pressure fluid is admitted to the cylinders F from a compressor H, the pressure fluid then provides the shock absorbing medium but other dashpots and dampers may be incorporated. Alternatively, the skid may be formed in three longitudinal sections hinged together, the forward part being hinged to the aeroplane body, two sets of inextensible and three of extensible members being provided. In this form, the skid, when retracted, lies along the bottom of the body. Various arrangements are described in which wheels are carried directly by the skid. More than one skid with its supports may be, fitted.
