Title: Improvements in or relating to mechanism for producing angular movement for use in retractable under-carriages for aircraft
IPC: B64C25/20
Filed: 1939-05-06
Abstract: 530,373. Retractable undercarriages for aircraft. AUTOMOTIVE PRODUCTS CO., Ltd., and SIMPSON, J. K. May 6, 1939, Nos. 13612 and 14636. [Class 4] [Also in Groups XXIX and XXXI] A retractable mounting for a wheel on an aircraft comprises a tubular strut adapted to move angularly about a substantially horizontal pivot shaft in the aircraft wherein is coupled to a crank on the pivot shaft, the piston being moved axially within the tubular strut to move the latter bodily about its pivot. In one form a retractable leg for an aircraft undercarriage comprises a tubular member 34 secured in a sleeve 12 pivoted about a fixed transverse trunnion 18. The trunnion, which is a fluidtight fit in the sleeve 12, is divided and the two parts are connected together by pins 23, 24 on a diameter which is at an angle to the axis of the tube in its normal position. The lower part of the tube forms the shock absorber which is separated from the upper part by a partition 17. A piston 33 in the upper part is connected by a rod 31 to the pin 23, and an extension 35 of the piston works within a second piston 36 having an extension 37. A spring 41 between the pistons normally urges the extension 37 into engagement with a fixed notch 57. Upon admitting fluid through a port 49 in the trunnion to the space above the piston 36, the extension 37 is first withdrawn from the notch and then the two pistons move together and turn the leg into the position shown in chain lines in Fig. 2, to retract the undercarriage. By admitting fluid through a port 56 in the opposite end of the trunnion into the space between the piston 33 and the partition 17 the leg is again extended. By admitting fluid also to the annular space around the shock absorber plunger the leg may be shortened. In a modification a single piston having an extension for actuating locking pawls has a lost motion connection to the connecting rod. Upon admitting pressure fluid the first movement of the piston effects unlocking of the leg in either of its two positions. In another modification the upper part of the tube is closed and a piston connected to one of the crank pins by a link works in the upper end of the shock absorbing cylinder. Movement of the piston to raise the leg consequently compresses the resilient shock absorber and energy is stored for re-entering the leg. The last two modifications may be combined so that the fluid acts on both pistons during retraction of the leg. The leg may form part of a permanent jacking device on a motor car so that the jack when not in use occupies a horizontal position and automatically moves into a vertical position when pressure fluid is admitted. Sealing rings as described in Specification 474,055, [Group XXVI], may be used to render the working parts fluid tight.
Patent GB-706858-A (GB)
Title: Production of semiconductive bodies
IPC: C30B15/04
Filed: 1951-06-08
Abstract: A semi-conductor body is produced by melting a mass of semi-conductor material, introducing a seed body therein, and altering the donor or acceptor impurity content of the molten mass.  In Fig. 1, a mass of semi-conductor material 16, which may be germanium or silicon, is melted in an induction heated crucible. A seed body 19 is suspended in the molten mass, and may be raised by means of a wire 23 controlled <PICT:0706858/III/1> <PICT:0706858/III/2> by electric motor 27 at a rate to draw some of the molten material therewith so that the material subsequently crystallizes.  A jet 28 which supplies a gas such as hydrogen containing water vapour is arranged to play upon the material after withdrawal.  The apparatus is enclosed in a bell jar 11 through which hydrogen or helium circulates.  Pellets containing donor or acceptor material are suspended in apertures in a plate 34 which may be rocked to slide against plate 32 so that a selected pellet rolls down tube 33 into the molten mass.  By this means the material may be converted to the opposite conductivity type or its conductive properties may be varied.  The arrangement enables a single crystal having successive portions of N P N P conductivity to be built up.  Phosphorus, antimony and arsenic are specified as suitable donor materials, and gallium, boron, aluminium and indium as acceptor materials.  As an example, a 20 milligram pellet of 0.2 per cent. gallium in germanium was added to 50 grams of molten germanium to convert to P-type, and then a 0.5 milligram pellet of 6.4 per cent. antimony in germanium was added to convert back to N-type, providing a crystal having a P type zone between two N zones.  Fig. 4 shows an alternative arrangement in which molten semi-conductor material flows from a reservoir 41 through a trough 40 to a second reservoir 44, and thence via pumps 46 back to reservoir 41.  A seed body 190 is partially immersed in the material in trough 40 and then withdrawn by a mechanism (not shown).  Rods 48a and 48b containing donor and acceptor material respectively may be inserted into the molten flow to change the conductivity.  A purification chamber may be provided in the system after reservoir 44.  Alternatively, the impurity may be introduced into the mass by a gas such as boron hydride or antimony hydride which is directed against the surface of the melt.  Specification 706,849 is referred to.

Title: Improvements in magnetic information storage devices using partial switching
IPC: G11C11/06
Filed: 1966-03-31
Abstract: 1,146,902. Circuits employing bi-stable magnetic elements. HOLLANDSE SIGNAALAPPARATEN N.V. 31 March, 1966 [3 April, 1965], No. 14377/66. Heading H3B. In a magnetic storage matrix in which for writing a binary digit a storage core in the saturated remanent state is driven to a partially switched state by coincidently applying two short duration and high intensity switching pulses, disturbance of unselected cores subjected to a single one of these pulses is neutralized by a further short duration pulse of reverse polarity which either precedes or follows the switching pulse. A word organized store is described in which read-out is effected by applying a current pulse to a word conductor sufficient to drive the associated storage cores to negative saturation, a larger flux excursion and therefore a larger pulse being induced in a digit conductor by a core storing a binary " 1 " than by a core storing a binary " 0." For writing, a word conductor is energized by a short duration and high intensity pulse sufficient to switch the core flux to an approximately zero value, i.e. midway between the saturation limits. At the same time each digit conductor is energized by a respective short duration pulse of lesser intensity the direction of which is determined by the digit identity " 1 " or " 0." Consequently the core flux switches either to point C, Fig. 2 (not shown), roughly midway between zero flux and positive saturation (binary " 1 "), or to a point D approximately midway between zero and negative saturation (binary " 0 "). The short duration pulse of reverse polarity which precedes or follows is applied either to the digit conductors or to separate conductors. A control circuit is described, Fig. 4, in which the read and write operations are determined by pulses from monostable triggers MSK1- MSK4, these pulses being produced from the outputs of a multivibrator MV by using a frequency divider 2D, differentiators d and an AND gate 401. Triggers MSK1, MSK2 alternately apply read and write control pulses which respectively operate gates 408, 413 to remove short circuits from current sources 409, 413 connected to the word conductor 411. Trigger MSK3 supplies a digit conductor 407 with a coincident pulse by removing at a gate 405, 417 a short circuit from the conductor, the direction of conductor current from sources 404, 408 being determined by a digit control pulse " 0 " or " 1 " applied to a respective AND gate 402, 415. Likewise AND gates 406, 414 cause a succeeding pulse of opposite polarity to pass to the digit conductor, a pulse from trigger MSK4 being applied through an OR gate 403, 416 to remove one of the short circuits at gates 405, 417. A two-core-per-bit arrangement may be used.
