Title: Time delay devices
IPC: H01H43/30
Filed: 1957-01-25
Abstract: 808,998. Switching systems for vehicle signalling systems. SIGNAL-STAT CORPORATION. Jan. 25, 1957 [June 13, 1956], No. 2868/57. Class 38 (4). [Also in Groups XXXVII and XXXVIII] A time delay device such as is used in a vehicle turn signalling arrangement comprising a pair of switch means each of which introduces a time delay in the functioning of the device whereby upon operation of the device to indicate a turn of the vehicle such operation is cancelled at the end of a period set by the sequential operation of the two switch means. The switch means 20 comprises two bent metal vanes normally deformed by pull members 16, 161 as disclosed in Specification 761,713, [Group XXXII], the pull members being heated by heater windings 35, 35<SP>1</SP> so as to expand to allow the metal vanes to move and close switch contacts associated therewith. Referring to Fig. 6, movement of a signalling control member 43 anticlockwise for example causes a latching member 69 to engage a detent 62 to hold the member 43 in the operated position and causes switch member 54 to complete a circuit between contacts 44, 52 whereby the signal lamps RF, RR flash under the control of a " flasher " unit 45, indication being shown on a pilot light PL. Simultaneously a further switch member 56 engages a contact 53 whereby a circuit is made from terminal 49 of the battery to earth through a bracket 25 of the switch means 20, vane 16, heater winding 35 and operating coil 55 of the latching member 61. The current in the coil 55 is not sufficient to operate the latching member 61 due to the heater winding 35 being in series therewith. As heater winding 35 heats and pull member 16 expands, after a pre-set time delay vane 10 moves such that contacts 31, 32 engage to close a circuit for the heater winding 35<SP>1</SP> in parallel with that for the heater winding 35. The current flowing in the operating coil 55 with the two heater windings 35, 35<SP>1</SP> in parallel is arranged to be less than that required to operate the latching member 61. As the heater winding 35<SP>1</SP> heats and pull member 16<SP>1</SP> expands, vane 10<SP>1</SP> moves after a second pre-set time delay to close contacts 36, 37 whereby heater windings 35, 35<SP>1</SP> are shortcircuited thus increasing the current in the operating coil 55 to retract the latch 61 so that the control member 43 is returned to normal by a spring 63. In a further embodiment the heater windings are wound around an auxiliary member secured to the pull member to produce a longer delay.

Title: Improvements in connection with plug switches
IPC: H04M1/08
Filed: 1925-02-03
Abstract: 246,669. Hale, S. M. Feb. 3, 1925. Plug couplings combined d with switches. - P lug switches for wireless receiving sets are sc arranged that a telephone may be plugged into any one of them. The base 2 of the switch is formed with a recess 3 to receive the shank of a hook member 4 for holding the telephone 6. The hook 4 is spring controlled to move upwards automatically in a known manner when the telephone is removed. At the upper end of the hook an insulated roller 8 bears against a spring blade 9 which it depresses against an abutment 11 when the telephone is on the hook, and so closes the circuit across the terminals 10 of the heads 1 of the set. The terminals 10 are further connected by strips 12 fitted to plug-in terminals 13, each of which has a fitting forming a contact 14 at one side and a spring clip 15 at the other. The clips 15 are adapted to press into a cut-away portion 16 in the terminals 13. The circuit is therefore normally closed across the plugs 13 whether the telephone is on the hook or not. If, however, the telephone leads 17 are plugged into the plugs 13 the springs 15 are forced away from the plugs and if the telephone is then lifted from its hook the telephone is in circuit.

Abstract: 545,305. Generators. BRITISH THOMSON-HOUSTON CO., Ltd., CLARKE, L. J., and WALKER, J. H. March 7, 1941, No. 3146. [Class 35] [Also in Group XXXIII] De-icing heaters attached to the airscrew or other rotatable part of an aircraft are supplied with alternating current by an inductortype alternator having the rotor and stator carried by the rotatable part and an adjacent fixed part respectively. The inherently high resistance of the alternator limits output at excessive speeds, and thus reduces the risk of burning out the heaters. The homopolar alternator shown in Fig. 1 comprises a rotor 6 and stator 15 attached to the hub 2 and housing 1 respectively. The rotor consists of a magnetic shell 7 and notched laminated cores 8, 9 provided with a single winding 10, or a pair, connected by leads 14 to the heaters. The stator comprises a channel-ring 17 containing a winding 20, and supporting staggered toothed rings 18, 19 which provide poles of different polarity. The winding 20 is connected by leads 21 to a source of direct current. The winding 10 may be so arranged that axially adjacent portions of the cores 8, 9 are of opposite polarity, in which case the parts 17, 18, 19 of the stator can be formed integrally. The parts 8, 18 may be omitted. The stator may be arranged externally to the rotor, and the field element may be carried by the rotor. The winding 20 may be replaced by permanent magnets. In this case, one of the rings 18, 19 may be rotatable, or the rings may be axially adjustable, to regulate the output. The heteropolar alternator shown in Fig. 5 comprises a rotor 9 having poles surrounded by coils, and a stator 15 having a winding 20, and poles 23 which vary in polarity from quadrant to quadrant. In modifications, the windings in alternate quadrants of the rotor are reversed, and the poles 23 are spaced uniformly; or both the rotor and stator may have uniformly but differently spaced poles.
