Title: Negative-temperature-coefficient resistors
IPC: H01C7/04
Filed: 1968-08-06
Abstract: 1,212,114. Semiconductor devices. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 6 Aug., 1968 [9 Aug., 1967], No. 37463/68. Heading H1K. [Also in Division C7] An N.T.C. resistor is made as a thin film of aluminium-doped silicon nitride on a substrate. The film may be shaped by etching or sandblasting to obtain the desired resistance value and may then be given superimposed Ni/Cr and Au films as electrodes. The resistor may be formed by reactive sputtering using a cathode which includes aluminium. Several masked substrates (of e.g. glass, ceramic, or mica) are placed on a rotatable anode (41) opposite a silicon-aluminium-faced cathode of the same size (a small cathode may be used if the rotational axis of the anode is offset). The cathode is liquid-cooled and is surrounded by an earthed protective ring (30). The chamber is provided with transparent loading windows (24) and is evacuated by floor ducts, the argon-nitrogen mixture for sputtering being fed into the space between the cathode and the protective ring. Cathode construction is as shown. The cathode of,Fig; 3 has a grid of Al wires 52 over a silicon surface 51 of mono or polycrystalline material as one piece or as many platelets-discharge to the Al ring 53 is prevented by the proximity of the earthed protective ring (30). The cathode of Fig. 4 has provision for varying the exposed area of Al. Al ring 65 with its attached Al sectors 62 may be rotationally disposed with respect to the other Al ring 64 and sectors 63 to vary the relative exposed area of Si 61 and Al. In a modification the anode may be modified so' that resistance monitoring of the deposited nitride may be used to control the thickness of the deposit.

Title: Improved hydraulically-controlled variable-speed gearing
IPC: B60K17/10
Filed: 1930-12-15
Abstract: 369,214. Variable-speed gearing. WOOLER, J., Willow Bungalow, West End Lane, Ruislip, Middlesex. Dec. 15, 1930, No. 37764. [Class 80 (ii).] Variable-speed gearing comprises an epicyclic train 29, 47, Fig. 3, controlled by fluid drawn from an outer fixed casing 49, Fig. 16, and passing radially by centrifugal action through a planet-carrying driving casing or flywheel 35, where it exercises a braking action on the planet-gears 29. The flywheel 35 is fast on driving-shaft 57, the sun gear 47 is fast on aligned driven shaft 48, and multiple planetgears 29 are rigid with spindles 28 extending outwards into hydraulic pump and turbine units shown in Fig. 3. Oil in outer casing 49 is carried by adhesion to ribs 35b, Fig. 16, on the flywheel 35 so that it enters a port at 55 and falls by gravity at 54 into a reservoir 51. It; then passes a control valve 56 and by a pipe 52 and nozzle 53 is directed into an annular cavity 35c, Fig. 3, in the flywheel. It then passes by ports 34 into gear pumps, one for each planet-arresting unit. This pump consists of a gear 31 fast on spindle 28 and meshing with a pair of gears 32 mounted so as to turn in cavities 22, Fig. 5, in a block 20, which is carried in a recess in the flywheel and has alhood 25 enveloping the planet gear 29 corresponding. From port 34 the fluid passes through two ports 33 into the pump, and then through ports 23 into cavities 24. Above the pump and engaging the axles 32a of the pump gears 32 are two plates 36, 37, and above these plates is a turbine-wheel 39 splined on the spindle 28. The wheel 39 is pressed inwards against centrifugal force by a ball-bearing ring 42 and springs 44 which abut on a screw cap 30. From the cavities 24 the oil passes into an annular chamber 36b between the plates 36, 37, and then through circumferentially-angled holes into wall-ended recesses 39d, Fig. 13, in the face of the wheel 39. The fluid passes back into an outer annular chamber 36c between the plates 36, 37, then out through ports 38 in the block 20 into an annular cavity 35a, then back through angled holes 40 into wall-ended recesses 39g in the outer rim of the wheel 39. The oil escapes through ports 43a, 30a. To the braking resistance of the pump are added backward couples due to the two rings of turbine recesses, the combined effect being to restrain the free rotation of the planets so as to apply to wheel 47 a torque which varies automatically with the load. The speed transmitted may be controlled manually by adjusting the valve 56, Fig. 16. High-speed solid driving is effected when the wheels 39 fly outwards and bind against friction surfaces 43, Fig. 3, and the speed at which this takes place is varied by adjusting the tension of the springs 44 by screwing the caps 30 by worms, not shown, engaging the toothed edges 45 of the caps 30.

Patent GB-891873-A (GB)
Title: Improvements in or relating to electro-magnetic relay switch arrangements
IPC: H01H67/26
Filed: 1960-11-03
Abstract: 891,873. Electrically released switches. TELEFUNKEN G.m.b.H. Nov. 3, 1960 [Nov. 7, 1959], No. 37877/60. Class 38 (5). [Also in Group XXXIX] A relay selector has a permanent magnet feeding a number of branch circuits each containing a gap spanned by an armature 4 and being embraced by a coil 5, each armature 4 being biased away from its associated gap but being held latched by the permanent magnet's field when the armature is closed across the gap, each armature being released from its latched position by energizing the associated coil 5. As shown in Fig. 3, the permanent magnet 3 has polepieces 1 and 2, the polepiece 2 having a set of parallel fingers projecting towards the polepiece 1 and defining a set of gaps which are bridged by armatures 4. Each finger carries a winding 5, only one of which is shown, and each armature is spring biased upwardly away from the gaps in the direction of the arrow P. If an armature 4 is pressed down on to its gap it is held down against the bias by the flux from the permanent magnet. If the coil 5 of a latched armature is energized in opposition to the permanent magnet the armature is released and moves away from the gap far enough not to be re-attracted by the magnet 3 when the coil 5 is de-energized. The normal condition of the armature is the latched condition so that the field set up by a coil 5 to release an armature has a return path along adjacent fingers and the field in the adjacent fingers is in the same direction as the latching flux from the permanent magnet 3 so that there is no tendency to release the adjacent armatures. Since the coil 5 acts in a low reluctance path, which does not include the magnet 3, release currents can be kept small. As shown in Fig. 4, the polepieces may each have oppositely disposed fingers across the ends of which the armatures are disposed, this arrangement allowing the coils more space, since they can be wound alternately on the fingers of each polepiece, and allowing the fingers to be spaced closer together to produce a more compact selector. As seen in Figs. 1 and 2, the selector comprises a frame with a base constituted by the polepiece 1 and pillars 9 at each end supporting cross-wires 8 which are common to the spring contacts 7 associated with each armature 4. In their normal position each set of spring contacts 7 is biased against the wires 8 and, by engagement with an operating card 6, also biases the associated armature 4 away from its operating gap. A magnet 12 with an armature 11 depresses all the cards 6 of the selector, allowing the armatures 4 to latch across their gaps and hold the spring sets 7 away from the wires 8 independently of magnet 12. One or more of the spring sets 7 may then be operated to make contact with the wires 8 by releasing the appropriate armatures 4 using the coils 5.

Abstract: 1480694 Signal horns ROBERT BOSCH GmbH 23 Sept 1975 [23 Sept 1974] 38913/75 Heading G5J An electromagnetic signal horn has a vibrating armature 14 fixed to a diaphragm 12; an electromagnet 15 with coil 16; a sensor 20 producing pulses in dependance on the position of the armature 14; a contactless switching device 49; and a multivibrator, the switching device 49 being arranged to interrupt current to the coil 16 for a period determined by the multivibrator each time a pulse is produced by the sensor 20. The sensor comprises a coil 21 which senses leakage flux #<SP>1</SP>; when the armature 14 engages the magnet 15 the leakage flux disappears inducing a voltage pulse in coil 21. In Fig. 3 the pulses are applied to trigger an astable multivibrator 23, shortening its natural period. The astable feeds a monostable 24 which determines the period of interruption. If the sensor is damaged and the pulses disappear the multivibator will operate the horn at a lower frequency ensuring the coil 16 is not damaged by the continuous current. The circuit may be simplified by omitting either the astable or monostable.
