Title: Over-temperature fuses for electric windings
IPC: H01H85/044
Filed: 1972-04-28
Abstract: 1392532 Fusible cut-outs ROBERT BOSCH GmbH 28 April 1972 [29 April 1971] 19755/72 Heading H2G An excess temperature fuse for electrical windings comprises a fuse element made of metal or an alloy of metals with a melting point between 70‹ C. and 250‹ C. and a flux in contact with the fuse element which expands or gives off gas when the metal melts, the fuse element being in good thermal contact with the windings to be protected. The metal or metal alloy and flux are chosen according to their melting temperatures and the desired cut off temperature. The melting temperature of the metal alloy can be adjusted, e.g. by mixing eutectic alloy with the fuse element and using a flux with a melting temperature greater or equal to that of the eutectic. When a metal eutectic alloy made from non- eutectic metals is used for the fuse element, a flux may also be used which has a melting temperature higher than that of the eutectic but within the softening range or over the upper limit of the softening range of the alloy used. Non-eutectic "surface alloys" may also be used for fuse elements. Examples of fluxes suitable for the fuse are urea, alietic acid and natural colophony with melting temperatures of 133‹ C., 173‹ C. and 110 to 130‹ C. respectively. Details of six compositions of various alloys used for fuse elements, their softening ranges, suitable fluxes and the flux melting points are given in the Specification. In one embodiment of the invention the element comprises a metal strip made from an alloy, of e.g. Bi, Pb and Sn in equal proportions by weight, which softens in the range 95‹ C. to 140‹ C. Wires are welded to the element and urea, melting temperature 133‹ C., is deposited on part of the surface of the element either directly or by placing a piece of urea enriched material on a surface portion of the element. The whole element is then sealed between two transparent synthetic sheets welded together around their perimeter. In a second embodiment of the invention the fuse element comprises a tube made from an alloy of 60% Sn and 40% Bi, proportions by weight, that softens in the range 138‹ C. to 170‹ C., that contains passages filled with alietic acid. Connecting wires are clamped to the ends of the passages. The tube is enclosed by a plastic insulating coating. In a third embodiment of the invention the fuse element is made from solid wire formed from an alloy of 50À5% Bi, 27À8% Pb, 12À4% Sn, and 9À3% Cd, preportions by weight that softens in the temperature ranges 158‹ C. to 163‹ C., the element being welded to connecting wires. Alietic acid flux surrounds the element and the whole is inserted in a heat resistant insulating tube, e.g. of polycarbonate. Alternatively the fuse elements of the above embodiments may be provided with a solid casing, e.g. by moulding or coating thermo or duroplastic synthetic materials around them.

Abstract: 625,737. Frequency modulation. PHILIPS LAMPS, Ltd. July 4, 1946, No. 20007. Convention date, July 6, 1942. [Class 40 (v)] Compression and expansion of the strong and weak portions respectively of an F.M. signal are produced at an F.M. transmitter and receiver respectively, to improve signal to noise ratio, and the mean frequency of the transmitted signal varied in correspondence with the volume of the modulating voltage to produce at the receiver a voltage restoring the correct amplitudes. A D.C. control voltage may be produced across a resistance 5, Fig. 1, from the modulator-amplifier 1 by a diode 4 and used to effect volume compression in the amplifier 1 and to deviate the mean operating frequency of the oscillator 2 accordingly as the modulation depth is less than the maximum. At the receiver, comprising a discriminator 12, a corresponding D.C. voltage is produced and applied to an amplifier 14 to restore the correct volume contrast. Specification 564,041 and U.S.A. Specification 2,006,989 are referred to. The Specification as open to inspection under Sect. 91 describes also a method for producing a D.C. voltage across a resistance 5, Fig. 2 (Cancelled), corresponding to the modulation intensity to amplitude modulate an oscillator 16 and transmitting from an aerial 3 a control signal the amplitude of which increases as the modulating signal decreases. At the receiver aerial a circuit 18 tuned to the control signal applies by way of a rectifier 19 and filter 20 a D.C. control signal to the amplifier 14 restoring the volume contrast. Expansion at the receiver may also be effected by varying the frequency of the frequency changer 9. This subjectmatter does not appear in the Specification as accepted.

Abstract: 841,337. Control of two motors; controllers; retractive switches. SWF-SPEZIALFABRIK FUR AUTOZUBEHOR G. RAU G.m.b.H. June 25, 1958 [Sept. 19, 1957], No. 20383/58. Classes 38 (3) and 38 (5). [Also in Group XXIII] A wiper motor 1 and a pump motor 2 for a combined wind-screen wiper and washing device in a vehicle are started together and then automatically stopped in sequence by means of time-delayed switching mechanism. The motors are started by pulling rod 19 so that contact-member 5 engages strips 8, 9, 10, and springs 11 are tensioned. When the handle 4 is released, the springs retract a member 20 having a toothed rack 26 engaging a pinion wheel 29 forming part of the delay mechanism, whereby the contact-member 5 is moved to the right. The motor 2 is disconnected when the contact-member disengages the strip 10, a gap being provided in the rack at this point so that a quick disengaging-action is afforded. A further toothed section in the rack allows the member 5 to slide slowly over the strips 8 and 9 and the motor 1 remains energized until another gap in the rack effects a quick break in a circuit for supplying the wiper motor. However, an alternative circuit is maintained for the wiper motor until the wiper reaches an end-position wherein the formation of a shortcircuit causes braking. As shown, the pinion 29 is coupled to an escapement wheel 32 cooperating with a pawl 33 on the axis of which is mounted a fly-wheel 34. A spring coupling 36 allows free rotation of the pinion when the rack is moved for starting the motors. The time-delay mechanism may be replaced by a bi-metal switch.
