Title: Improvements in or connected with adjustable seats particularly suitable for aircraft
IPC: B64D7/02
Filed: 1935-11-12
Abstract: 465,734. Adjustable seats. VICKERS (AVIATION), Ltd., and WALLIS, B. N. Nov. 12, 1935, No. 31267. [Class 52 (ii)] A seat g<1>, Fig. 1, particularly for use in aircraft cockpits as described in Specification 449,237, is pivotally mounted on an angularly adjustable arm c<1> having a device thereon, such as fluid-pressure-operated means within a cylinder d, for applying torque to raise the seat and for resisting the lowering of the seat, gearing such as e, e<2>, e<4> being associated with the arm for adjusting the angular relationship of the seat to the arm during angular adjustment of the arm. The velocity ratio of the gearing may be such as to cause backward and forward tilting movements of the seat as the arm moves up and down. Further, the gearing provides means for retaining the seat in adjusted position. The seat shown is mounted by means of a spring-resistor d on an L-shaped frame a fixed to a turntable b all as described in the abovementioned Specification. The supporting arm is in two parts c, c<1> forming the movable elements of the spring-resistor d and connected at their outer ends by a tube f forming the seat pivot. The fixed portion d of the resistor has toothed sectors e for causing rotation of the gearing e<1>, e<2>, e<3> during the pivotal movements of the arms. The bevel pinions e<3> engage on one side with toothed sectors e<4> keyed to the tube f and on the other side with toothed sectors e<6> slidable on feathers on the tube into and out of engagement with the pinions for locking and unlocking the gearing. For this purpose, the sectors are connected to pistons e moved oppositely in the tube f against the action of return springs e<12> by pressure fluid admitted at f<4>. The arrangement is such that, when pressure is supplied to or released from the cylinder d to raise or lower the seat, the controlling valve places the opening f<4> to exhaust to permit the pistons to return and unlock the seat. The pistons may also be moved to locking position independently of the fluid pressure by manually operated screws e<15>. The turntable is locked in position by remotely-controlled means h<1>.

Abstract: 1,243,883. Automatic warehouses. VSESOJUZNY PROEKTNO - KONSTRUKTORSKY INSTITUT SVAROCHNOGO PROIZVODSTVA. 24 June, 1969, No. 31713/69. Heading B8E. [Also in Division A4] In an automatic warehouse, Fig. 1, the bottoms of the storage units 3 and of the loading and unloading tables 1, 2 comprise bars 9 which are arranged with their bearing surfaces lying on a curve and the stacker vehicle 4 has lifting forks provided with similarly arranged tines which pass between the bars 9 for loading and unloading. Vertical side shields 11 are provided on the tables, storage units and stacker vehicle to prevent goods being dislodged sideways. The stacker vehicle is driven along rails 7, Fig. 2, by an electric motor 24 and the forks are raised and projected respectively by motors 29, 34. The stacker vehicle is controlled by punched cards inserted into a programming device 8, Fig. 1. Fig. 3 shows mechanism for accurately arresting the stacker opposite a desired location. When an electromagnet 13 is operated a pawl 17 is lowered to engage a stop 23 thus causing a slide 19 with a cam 20 to be displaced. This operates a limit switch 22 to stop the drive motor and energize the brake. As the stacker continues to move slowly due to inertia, the slide engages a rigid stop 18 which stops the stacker in the desired position.

Title: Improvements in or relating to control devices responsive to the attraction by an electro-magnet of the armature thereof
IPC: H01H67/26
Filed: 1956-10-18
Abstract: 802,409. Electric signaling. TELEFONAKTIEBOLAGET L. M. ERICSSON. Oct. 18, 1956 [Oct. 19, 1955], No. 31749/56. Class 40 (1). [Also in Group XXXIX] The primary winding of a transformer is connected in series with the select magnet of a cross-bar switch so that the momentary reduction P of the energizing current, Fig. 1, which occurs when the armature pulls up induces voltage pulses UA, UB, Fig. 2, in the transformer secondary winding. These pulses indicate effective operation of the magnet and are used to initiate further switching operations without delay. An application is described, Fig. 4, in which a free link circuit SN is connected to a calling line L by line identifying equipment D. When a call is initiated, line relay LR pulls up and the line is identified by operation of characterizing relays such as D1, U1 in the Groups D1-D10 and U1-U10. Relay D11 and a relay V 10 in a link selection Group V1-V10 also respond, the latter relay pulling up N2 and N3 in a free link circuit SN and operating K1 so that a short circuit is removed from the secondary winding of a transformer T. A select magnet M10 in a magnet Group M1-M10 of a cross-bar switch comprising spring sets a, b, c, is energized at this stage, and since the transformer primary winding is in the series circuit, voltage pulses UA, UB are induced in the secondary when the magnet operates. As a condenser C is connected to the secondary winding, currents are produced in the form of pulses IC, IA and IB, as shown in Fig. 3. The first pulse IC is suppressed as it arises before K1 operates, the second pulse IA charges the condenser over a rectifier E, and the last pulse IB discharges the condenser through a resistor R and fires a gas tube GL. Relay K2 then responds and the switch hold magnet BR pulls up, both locking in the operated position. The link circuit taken into use is busied by operation of N1, while the line relay LR falls back and frees the identifying equipment. In a modification, Fig. 5, the induced voltage pulses UA, UB, Fig. 2, are utilized to trigger a biased transistor S. In this case operation of K1 connects the transistor into circuit, and the voltage pulse UA neutralizes the bias and causes the transistor to conduct. Relay K2 responds as before and induces a positive feedback voltage for the transistor in a second winding so that the emitter current is increased.

Title: Improvements in or relating to reversible magnetic shift register
IPC: G11C19/04
Filed: 1956-10-19
Abstract: 850,732. Circuits employing bi-stable magnetic elements. LABORATORY FOR ELECTRONICS Inc. Oct. 19, 1956 [Oct. 26, 1955], No. 31985/56. Class 40 (9). [Also in Group XIX] A shift register composed of saturable magnetic cores is operable in one direction or the other selectively. Each stage comprises only one core, a condenser acting as an intermediate storage element. Shift pulses are applied to windings 1 or 2 on the cores and similar positive biasing pulses are simultaneously applied to a lead 24 and, by means of a selecting switch device 23, either to lead 21 for rightward shift or to lead 22 for leftward shift. In the case of rightward shift, the pulses applied to points 7 and 15 permit a diode 9 to conduct and, if the first core 5 is reset by the shift pulse, the output pulse induced in a winding 3 thereon will charge the storage condenser 13. At this time, any pulse in the output winding 4 of the next core 6, which is reversely wound to the winding 3, is blocked by a second diode 11, the other end 8 of the winding 4 being earthed. when the biasing pulses cease, the condenser 13 is able to discharge through the winding 4 and so to set the core 6. The shift from the core 6 (stage 2) to the next core 5 (stage 3) is similar but the potentials and the diodes are reversed. When the switch 23 is set for leftward shift, an output pulse, e.g. in the winding 4 of the core 6, is passed by the diode 11 (the points 8 and 15 both being earthed) to charge the condenser 13 which later discharges through diode 9 to set the core 5. The diode 10 is now non-conducting owing to the positive bias pulse on lead 22, the point 8 being earthed. Specification 850,586 is referred to.

Correctors C1, C2, C3 are sequentially connected in circuit between A, A<SP>1</SP> and at the same time, the respective errors on line D are sequentially applied via delays M1, M2, M3 and counters K1, K2, K3 to stores Y1, Y2, Y3. The three stored signals are then compared in amplifiers A1, A2 to produce outputs on lines E, F which are either positive or negative depending on which stored signal is the smallest. Signals E, F are then applied to circuit 35 to produce corresponding outputs b1, b2, b3 which connect into circuit the corrector C1, C2, or C3 which gave the minimum error. Comparator details.-If V2 is smaller than V1 transistor Q is cut off and relay R remains deenergized applying a negative signal to input E of circuit 35, and connecting V2 to the positive input of amplifier A2. If V1 is smaller than V2 transistor Q conducts, energizing relay R to apply a positive signal to input E and to connect V1 to the positive input of A2. The polarity of signal F will then depend on whether signal V3 is greater or less than the signal (V1 or V2) with which it is being compared. Circuit 35 details, Fig. 3-If F is positive, transistor Q1 is switched on by a pulse from source 30 to set bi-stable B3 producing output b3 and transistors Q5, Q6 are held non-conducting to prevent bi-stables B1 or B2 being set. If F is negative, the state of B3 allows Q5, Q6 to conduct. Application of a positive signal E then. turns on Q7 to set bi-stable B1 and application. of a negative signal E turns on Q8 to set bistable B2.
