Title: Phase detector fault indicator
IPC: H03L7/095
Filed: 1957-05-10
Abstract: 815,038. Phase indication. COLLINS RADIO CO. May 10, 1957 [July 16, 1956], No. 14956/57. Class 37. [Also in Group XL (c)] A phase discriminator 10 has portions of its two inputs rectified by rectifiers 26, 34 and separately applied to different grids of an auxiliary valve 17 to render it normally conducting, and part of its A.C. output, when the inputs are out of synchronism applied through a D.C. blocking capacitor 42 to a further rectifier circuit, e.g. voltage doubler 46, 44, 43, whose output opposes the conductive bias across capacitor 36 on one grid, so that out of synchronism or low amplitude of either input cuts off the valve 17 and operates an alarm sounding relay 56, 58. On synchronism being reached, its output being D.C., the valve conducts to stop the alarm, provided both inputs have sufficient amplitude. Alternatively the relay may operate a light or disconnect equipment. The valve may be a 6BN6 gated beam tube with amplitude limiting characteristics and constant cathode current, producing across a cathode circuit potentiometer 21 a variable cut-off bias applied to the grid 19. The circuit may be applied to frequency and phase stabilization systems.

Title: Improvements in and relating to locking gear for the landing doors or gates of lifts
IPC: B66B13/18
Filed: 1936-05-27
Abstract: 474,928. Locking well-doors of lifts. EXPRESS LIFT CO., Ltd., and WELLS, L. E. W. May 27, 1936, No. 14976. [Class 78 (iii)] For locking well doors and gates so that unlocking can only be effected when the cage is at the corresponding landing, solenoids on the cage are energized to attract a pivoted plate mounted in the well and move it angularly, thus closing a switch which energizes a solenoid to withdraw a locking bolt from the well-door. Fig. 1 shows the solenoids 1, 2 mounted on a bracket 5 on the top of the cage. Fig. 4 shows the member 4, of sufficient length to allow for slight inaccuracy in levelling, which is moved by the solenoids in a vertical plane on the ball-bearing hinges 15 against the action of a spring 21, and in moving causes a tail-piece 8 to close a switch 17 thus bridging the leads 19 controlling the lock-releasing solenoid (not shown). A bridge member 23 co-operates with a bolt 22 to limit the movement of the member 4. in both directions. The solenoids 1, 2 preferably are energized in conjunction with the car-stopping relay, so that they only become effective to release the lock when the car has actually stopped. In a modification a single solenoid is used on the cage and a forwardly-projecting arm on the bracket 5 contacts the attracted plate 4 and completes the return circuit for the energizing current.

Abstract: 1470515 Micro-pipette apparatus FLOW LABORATORIES Ltd 29 March 1974 [30 March 1973] 15488/73 Heading G1B An automatic micro-pipette shown generally in Fig. 2 comprises a capillary pipette tube 2 with a dropping tip, a reservoir 3 for liquid to be dispensed which together with tubes 5, 7, 8 and 9 forms a closed container of variable internal volume and a dispensing control mechanism formed by members 12 to 23 operative to vary, by compressing the flexible tube 8. The internal volume of the closed container in a dispensing cycle, wherein the pipette tube 2 opens directly out of the reservoir 3 and at least the upper part of the pipette tube has a bore of such fineness that, in operation when the closed container has a predetermined maximum internal volume, a meniscus forms at a reference position at one end of the fine bore, the operation of the dispensing control mechanism causing firstly a reduction in said internal volume to cause liquid to drop from the pipette tube and then secondly an increase in said volume so that the meniscus returns to said reference position. The increase in internal  volume is normally equal to the reduction in volume so that air bubbles into the container through the pipette tube to make up for the volume of the liquid dispensed. In operation, pressure on button 12 motivates screw 19 to depress cantilever 20 causing block 21 to compress flexible tube 8 and expel liquid through the pipette tube. The apparatus may comprise eight sets of pipette tubes, reservoirs, closed containers, cantilevers 20 and blocks 21 operated by a single button 12. The reservoir 3 may be filled by pivoting the whole apparatus downwards about pivot 29 so that the end of pipette tube 2 is immersed in liquid in container 26, valve 10 is released and the reservoir filled by operating the flexible aspirator bulb 11. An anti-splash baffle 38 restricts liquid to reservoir 3 during filling.

Abstract: 422,340. Electromagnetic interrupters. VOSS, A. E., 7, Wentworth Mansions, Keats Grove, Hampstead, London. July 3, 1933, No. 15688 /32. [Class 38 (v)] An electromagnetically-actuated interrupter comprises a pivoted arm 1 carrying an armature 7, and a mercury switch 9 supported in an adjustable container 12, mounted at the pivotal axis 2, contacts of the switch controlling the circuit of an electromagnet 8 in such a manner that the arm 1 reciprocates as a pendulum when the external circuit is completed. The mounting of the switch 9 thus ensures that practically no translational movement of the container takes place and undesired surging of the mercury in the container is avoided. The arm 1 in its movements is arranged to control a second tilting mercury switch 17 controlling the circuits of advertising signs, &c., the switch 17 being mounted (Fig. 3) in a pivoted carrier 21 having an arm 24 carrying a pin bearing on the periphery of a cam member 26. As the arm 1 oscillates a pawl 14 carried thereby steps round a ratchet wheel 15 which moves round the cam 26, the shape of which is such that in succeeding alternate steps the switch 17 completes two circuits successively, the contacting positions being separated by steps in which both circuits are broken. The armature 7 and the polepieces 13 of the electromagnet 8 may be formed of laminated material. The adjustment of the interrupter switch 9 is effected by loosening a screw 121 and rotating the container about the pivotal axis 2. This varies the point of interruption and the amplitude of oscillation of the pendulum. In an alternative arrangement two alternately acting electromagnets may be provided for oscillating the member 1.

Title: Improvements in or relating to the manufacture of magnetizable powder cores
Inventor: TOMBS NIGEL CONRAD
IPC: C23C24/04
Filed: 1955-06-01
Abstract: A magnetic core is made by ball-milling particles of a magnetic metal or alloy with bodies of a physically softer metal to coat them with the softer metal, and subsequently coating the particles with insulation including at least one layer of inorganic material and compressing to the desired shape and annealing at about 500 DEG C. The coating of softer metal which amounts to less than 5 per cent, preferably about 1 per cent by weight of the powder, may be partly or wholly removed before application of the insulation.  In one example, electrolytic iron is heated in hydrogen, sieved, milled with aluminium balls, resieved, coated with two applications of a mixture of china clay, magnesium oxide and sodium silicate, compressed at 40 tons/sq. inch to a ring and annealed at 600 DEG C. in hydrogen. Alternatively before the insulation is applied, the aluminium coating is removed with boiling potassium hydroxide.  Also described is the production of cores in which the iron powder is coated with zinc and zinc-aluminium alloy by rolling with suitable balls.  Other magnetic materials mentioned are iron-nickel and iro-nickel-copper, alloys, and alternative softer metals are tin and magnesium.  An outer layer of insulation comprising a theromsetting resin, a cellulose derivative or sugar may be applied.  Specification 676,136 is referred to.
