Title: Improved lock for electrically operated lifts
IPC: E05B65/00
Filed: 1922-03-22
Abstract: 185,372. Thomas, H., F., and Newbury, G. March 22, 1922. Lift cages and doors, locking and operating.- A well-door lock for an electrically-actuated lift contains two pivoted contacts 2, 3 which are separated by the upward movement of a bolt 5 caused by the withdrawal of the latch 10, and remain separated until there-insertion of the latch places a pivoted support 12 below the contact 3. The bolt 5 is held down by springs 7 and has projections 8, 9 which engage. successively with the contacts 2, 3 respectively, and so break the circuit. The support 12 is forced by the spring 13 towards the latch 10, so that when the latch is withdrawn and the belt has fallen, no support is provided for the contact 3 and the circuit remains broken. An arm 15 on a rock-shaft 14 carries a roller 16 in the path of the lift. When this shaft is rocked an obstruction to the upward movement of the bolt 5 is removed.

Title: Improvements in steering gear for vehicles
IPC: B60G11/22
Filed: 1928-03-20
Abstract: 287,506. Lavaud, D. S. de. March 22, 1927, [Convention date]. Springs, arrangement of; guiding vertical play; lateral movement, preventing; equalizing load on wheels.-The Specification as open to inspection under Sect. 91 (3) (a) comprises a construction in which the front axle 14, Figs. 5 and 23 (both Cancelled) is of double banjo shape and is pivoted on the longitudinal axis of the car, being mounted on a compressed rubber ring 16 on a boss 4 fixed to the frame end clamped with some friction by a nut 19 between friction washers 13, 17. At each end is secured by rivets 33 and soldering a casting 32 bored out for the steering pivot 41 of the stub axle 42. The pivot 41 slides and rotates in a tube 36 secured to the axle end, and a plunger 53, fixed to the axle by a stem 54, ball thrust bearings 60, and a cap 59, bears on a cylindrical rubber cushion or spring 52 supported on a plate 50 carried by the lower end of the stub axle pivot tube 41. The sides of the cushion 52 are constrained by means of rings 72. Rebound of the axle is checked by means of an upper rubber cushion 68 mounted between the plunger 53 and a plate 69 secured to the tube 41. The rear axle 73, Fig. 6 (Cancelled), is centrally pivoted by a rubber joint to a block which is constrained to move vertically relatively to the frame either by linkage (not shown) or by the vertical guide shown in Fig. 7 (Cancelled). A bolt secured to axle carries a block round which is placed a rubber sleeve fitting within a block 86 carrying friction plates 92 engaging vertical guides 95 carried by the main frame. The guides are pressed towards the friction surfaces by adjustable spring blades 99. The main frame bears on each end of the rear axle through rubber springs 148 interposed between a plunger 146 carried by the frame and a plate 133 supported by a link 129 ball-jointed to the plate and the axle-end. The lower balljoint comprises rubber half-balls 126, 127 enclosed in a two-part shell forming the link 129. The plunger 146 is fixed to a tube 141 forming an extension of the tube 136 cast with the frame. Rebound is checked by a rubber cushion 152 mounted between the plunger and the top end of a tube 132 which slides within the tube 141 and encloses the main spring 148. Rings 149 limit the bulging of the spring 148. This subject-matter does not appear in the Specification as accepted.

Abstract: 1307692 Cartridges FRANCE ARMED FORCES MINISTER OF AND COMPAGNIE FRANCAISE THOMSON HOUSTON-HOTCHMSS BRANDT 23 Feb 1970 [4 March 1969] 8621/70 Heading F3A A cartridge comprises a tube A having a closed end 3 and housing a plurality of missiles B<SP>1</SP> ... B<SP>n</SP> one behind the other. The tube A has mounted thereon for each missle a firing means by which the missiles are fired in succession and one at a time. Each firing means comprises a device C<SP>1</SP> in which is housed a detonator 26, a relay 17 and a powder charge 18, the detonator 26 being, before firing, separated from the relay 17 by a head 23 of a missile locking means 19 and the powder charge 18 being in communi. cation with a chamber 8 formed between two adjacent missiles. The locking means 19 is held in its missile retaining position by a split ring 22. The firing means also includes a pair of switches housed in a cover 30, the first switch being held in a position in which a lead D<SP>1</SP> is electrically connected to the detonator 26 by the insulated stem 32a of a valve member 32 and the second switch being held in a position such that the lead D<SP>1</SP> is disconnected from a following lead (D<SP>2</SP>) which connects with the detonator of the following device (C 2 ) by the stem 37<SP>a</SP> of a piston 37. On firing the detonator 26, the head 23 is urged upwardly such that the retaining action of the split ring 22 is overcome. Gases from the detonator 26 then impinge on the relay 17 to ignite the charge 18. At the same time a ball 34 held in a passage between the head 23 and the valve member 32 and retaining the valve member 32 seated is released but residual gases from the detonator maintain the valve member 32 seated. When the missile has substantially passed the device C<SP>1</SP> pressurized gases pass through a aperture 39 to act against the piston 37 shearing a piston holding pin 38 and allowing the contacts of the second switch to make. When the missile leaves the tube A the gas pressure therein drops as therefore does the pressure acting on valve member 32. Thus the valve member 32 unseats to withdraw its stem 32a from the cover 30 to allow the contacts of the first switch to make. If the potential is maintained permanently in the lead D 1  the second device (C<SP>2</SP>) will then be actuated.

Title: Improvements in or relating to steam engine plants provided with auxiliary machines
IPC: F01K7/36
Filed: 1932-03-30
Abstract: 395,107. Power-generating systems. AKTIEBOLAGET GÍTAVERKEN, Gothenburg, Sweden. March 30, 1932, No. 9163. Convention date, Nov. 28, 1931. [Class 122 (iii).] A multipleexpansion marine power plant is adapted to supply steam at reduced pressure to the auxiliary machines and steering-engine. All or part of the auxiliary machines are driven by intermediate steam taken from the engine and increased in pressure and/or superheated bv a compresser. The auxiliary machines 9, and steering-engine 10 are fed from an auxiliary main 8 supplied with line steam through a reducing-valve 11 and/or with main-engine receiver steam through a non- return cut-off valve 16 and a pipe 15 supplied from a turbine-driven compresser 17 operated by the low-pressure exhaust through a pipe 19 which turbine circulates steam through pipes 25 and a steam collector 27. The exhaust from the auxiliaries pass to a feedwater heater 13. The valve 11 is adjusted to supply steam at a pressure below that in the conduits 25, 15. The receiver 5 is divided into two parts, one takes the exhaust from cylinder 2 and supplies the compresser, the other receives the discharge through a control valve 26 and supplies cylinder 3. The pipe 15 supplying the auxiliaries is connected to the collector 27. When the main engine stops or when the receiver pressure falls, the auxiliaries are driven by reduced boiler steam. Apparatus and arrangements for heating purposes may be connected to the pipes 15, 8. Some auxiliaries may be connected to one receiver, and the others to another. Some auxiliaries mav be driven solely by reduced boiler steam. The compresser 17 may be driven by a separate source of power, and may also be connected into either one of the conduits 15 and 8 to compress and reheat the steam for all or some of the auxiliaries. An additional compresser may be arranged in either conduits 15, 8. The compresser may effect rise of pressure or superheating, or throttle resistances may be placed in the compresser pressure conduit. Drying or superheating may be effected by a fluidgas heater.
