Abstract: 837,891. Vehicle power steering. BRITISH MESSIER Ltd. July 11, 1956 [July 20, 1955], No. 21053/55. Class 79(5) In an aircraft steerable undercarriage having a rotatable member 112 carrying landing wheels and supported for a limited range of rotation by a fixed element 111 secured to the airframe (not shown), the member 112 is connected to a member capable of rotating it by a set of two driving abutments for each direction of rotation, the sets comprising steps 167, 168 on one member and roller-carrying arms 137, 138 pivoted to the other member, the arms being movable between positions in which the rollers 149, 150 engage the steps and are clear of the steps. As further shown a collar 163 keyed to the member 112 has the steps 167, 168 and the rollers 149, 150 are mounted by pins 147, 148 on the arms 137, 138, the pins also carrying further rollers 153, 154 engaging slots 173, 174 having end seats 175 formed in flanges 171, 172 secured to the element 111. The arms 137, 138 are interconnected by a spring 166 and are pivoted by pins 139, 140 to bosses 133, 134 on a flange 120 on an annular member 119 rotatably mounted on the member 112. Spigots 125 on the flange 120 and a further flange 121 on the member 119 support a power cylinder 128, the piston rod 130 of which is pivoted to a flange 132 on the element 111. Power steering is effected by axial movement between the rod 130 and cylinder 128 whereby the cylinder is rotated relatively to the element 111, the cylinder being connected to a control valve (not shown) of the follow-up type for centralizing purposes, the valve being connected to a pilot's control (not shown) having a cam adapted to cooperate in the extreme positions of the control with a micro-switch connected with a limiting valve in the pressure line leading to the control valve. Such rotation causes similar rotation of the member 119 resulting through a thrust on one of the arms 137, 138 and co-operation between one of the rollers 149, 150 and its associated step 167 or 168 in rotation of the member 112 and hence steering the aircraft landing wheels. When the aircraft is being towed through a bar (not shown) connected to the member 112, the member 112 can be rotated beyond the normal range of rotation (which may be 35 degrees from the straight ahead position) by one of the rollers 153, 154 being forced into one of end seats 175 thus permitting the associated step 167 or 168 to pass under the roller 149 or 150.

Abstract: 645,732. Electrical proximity indicators. FIELDEN (ELECTRONICS), Ltd. Aug. 10, 1948, Nos. 21065 and 32546. [Class 37] [Also in Group XL (c)] Apparatus for operating a switch in accordance with the proximity of an object comprises an oscillator whose feed-back is controlled by the capacity of an electrode associated with the object to start or terminate the oscillations, and thereby cause an associated thyratron valve to energize or de-energize a relay. The electrode is attached to the conductor a of a co-axial cable to introduce a capacity C3 (not shown) into a Hartly oscillator circuit comprising valve V2 and associated components so that the feed-back phase is determined by the relative values of capacity of C3 and of an adjustable condenser C2. The oscillations are fed to the grid of a thyratron V1, the anodes of V1 and V2 being fed from an A.C. supply in anti-phase so that V1 can only fire every half-cycle. When V2 is not oscillating, relay r in the anode lead to V1 is energized during firing and maintained energized during the alternate half-cycles by condenser C4 across it. When V2 is oscillating, the rectified oscillator volts charges condenser C1 in the grid circuit of V1 and prevents firing. The contacts of relay r may operate lamps and other control circuits. The change in capacity of the electrode may be caused by the movement of liquid in a thermometer, or the movement of articles along a conveyer belt, or the proximity of a meter needle to a pre-set pointer.

Filed: 1948-08-12
Abstract: 653,131. Supply systems for space discharge apparatus. GENERAL ELECTRIC CO., Ltd., and WILLOUGHBY, A. H. Aug. 12, 1948, No. 21304. [Class 38 (iv)] A succession of high voltage pulses of equal amplitude are provided to start a discharge lamp operating from D.C. particularly a H.P.M.V. lamp, by starting means under the control of operating means adapted to cause the starting means to generate automatically a plurality of the pulses in rapid succession which preferably is arranged to commence upon restoration of a supply failure and continue until the device starts or an automatic cut-out operates in the event of a lamp failure. In the arrangement described the starting means comprises a transformer, the secondary 8 of which is connected across the lamp 1 and the primary 9 is connected through contacts 10 actuated by a relay coil 14 to a D.C. supply, and which is under the control of operating means comprising a relay coil 17 associated with change-over contacts 15, 16, and a condenser 20 arranged so that upon closure of switch 19 relay coil 17 is energized over contact 16 whereupon contact arm 18 disengages from contact 16 to de-energize coil 17, and momentarily make with contact 15 to energize coil 14, hence close switch 10 and thereby provide a current pulse in the transformer primary. Whilst contacts 15, 18 are closed condenser 20 is charged and the relay coil 17 is gradually de-energized until contact arm 18 re-engages with contact 16. The time interval between pulses can be controlled by varying the capacity of the condenser. Values of coil resistance and condenser capacity are given to provide three pulses per second. The operating means may alternatively comprise a motor driven commutator and the automatic cut which may actuate switch 19 may operate to open the switch in response to the lamp discharge current and close the switch upon restoration of the supply after failure. The lamp operating circuit may include in addition to resistive ballast 6 a choke 7 to prevent the pulses being fed back into the supply source. Terminals 4, 5 ; 12, 13 ; 21, 22, may be coincident.

Abstract: 700,217. Stamping. SCHULER AKT.-GES., L. Sept. 11, 1951 [June 7, 1951], No. 21371/51. Class 83 (4) In a drawing press the drives to the drawing slide and blank holder slide are so arranged that the drawing slide is at rest during the closing stroke of the blank holder slide, and the drawing commences near the withdrawn position of the drawing slide, which is preferably a dead centre position of its driving members. The draw slide 30, Fig. 2, is driven by a connecting rod 29 connected to a gear wheel 27 driven from a driving pinion 6<SP>1</SP> meshing with a gear wheel 8 rotatable on a shaft 28. Rocker arms 21 on this shaft 28 carry shafts 22, 23 carrying gears 24-26' which cause the wheel 27 to rotate oppositely to wheel 8. Thus if the rocker arms are rocked about the shaft 28, the wheel 27 and hence the draw slide 30 are accelerated or retarded according to the direction of movement of the rocker arms. The arrangement may be such that the retardation brings the slide to rest while acceleration effects its rapid return, and the draw takes place with the rocker arms at rest and held fast. Figs. 1 and 3, (not shown), show modified arrangements, with the wheel 27 rotating in the same direction, and with a jointed shaft in place of the shaft 23. The drive to the blank holder slide 19, Fig. 4, is derived from an eccentric 9 rotating with the shaft 28, the arrangement having links 39, 39<SP>1</SP> to which may be coupled draw bars 20, 20<SP>1</SP> acting on the shaft 23, Fig. 2, which carries the planet gears 26, 26<SP>1</SP> of the draw slide drive. The drives from the draw bars 20, 20<SP>1</SP> to the shaft 23 may include a coupling such as a friction disc clutch by means of which the angular position of the crank wheel 27 relative to the eccentric 9 may be adjusted. Fig. 8 shows a press incorporating drives of the type shown diagrammatically in Figs. 2 and 4, there being two connecting rods 29 connected to the draw slide 30 and four straps 19<SP>1</SP> connected to the blank holder slide 19.

Underwater breathing-apparatus comprises a mask which covers the nose leaving the mouth exposed and means providing a substantially constant air pressure within the mask above the ambient water pressure and controlled automatically by the water pressure. The mask 4 includes a window 6 and is held airtightly over the eyes and nose by a strip 8. A regulating valve comprising a casing 3 is mounted on the mask, the interior of the casing communicating with the interior of the mask. A compressed-air cylinder 1 is connected by a tube 5 to a short tube 9 which passes through the casing wall. Within the casing, a sleeve, mounted over the outlet end of the short tube, guides movement of a valve stem of a valve member 13 which is urged by an adjustable spring 18 to close the short tube outlet. The valve stem bears against one arm of a bell-crank lever 16, the other arm of which is attached to a diaphragm 23 which separates the casing interior from the ambient water. The valve is so adjusted by the spring that it is closed by movement of the diaphragm when the pressure in the casing and the mask is just above the ambient water pressure. If the pressure in the casing falls relative to the water pressure due to the driver descending to a greater depth or inhaling, the diaphragm moves to open the valve so that air is introduced to restore the differential pressure between the mask and the water to the amount, slightly in excess of the water pressure, which is determined by the adjustment of the spring.
