Title: An improved arrangement for obtaining synchronisation of rotatably-driven elements
Inventor: APPLEBY WILLIAM EDWARD
IPC: H02P5/46
Filed: 1949-11-28
Abstract: 667,238. Synchronous movements. EDISON SWAN ELECTRIC CO., Ltd. Nov. 28, 1950 [Nov. 28, 1949], No. 30508/49. Class 40 (iii). [Also in Group XV] In an arrangement for synchronizing the rotation of a plurality of rotatably-driven elements synchronous driving means rotate the elements through friction clutches, stops operated by electromagnets are arranged to engage and hold each element in a predetermined position and a time lag switch associated with all the electromagnets is provided to operate the magnets to hold the elements in their predetermined positions to bring them into step and thereafter to release them simultaneously so that they are driven in synchronism. The invention is described in connection with floodlighting equipment where it is desired to start in synchronism and maintain in step elements carrying multi-colour translucencies in a number of floodlight units. In such equipment, current from the main supply is fed through the main switch 7 and main fuses 3, 4, to main distribution lines 5, 6. A third distribution line 10 is fed through time-lag switch 8. The units, of which one is shown, are attached to the three distribution lines and include fuses 11, 12 and 13, the lamp of the floodlight 21 connected across lines 5, 6; synchronous motor 16 across lines 5, 6, and arranged for self-starting over a circuit through condensers 14, 15; and also solenoid 22 connected across lines 10 and 5. When the equipment is switched on the lamps 21 light and the motors 16 start and run up to synchronous speed driving the colour change elements which may be cage-shaped through friction clutches. The solenoids 22 are also energized to raise spring-loaded catch members which contact projections on the colour elements as these reach predetermined positions and prevent them moving further. After a given time during which all the elements have been stopped the time-lag switch 8 opens, the catches drop out; and the colour elements commence to rotate at the same time and in synchronism. A press-button 9 is provided on the switch 8 so that the switch may be operated to re-synchronize the elements should these for any reason get out of step during running.

Title: Ionization fire alarm with insulation monitoring
Inventor: SCHEIDWEILER ANDREAS
IPC: G08B17/11
Filed: 1970-06-24
Abstract: 1291755 Ionisation smoke detectors CERBERUS A G 24 June 1970 [24 June 1969] 30653/70 Heading G1N In an ionisation fire alarm, an alarm is provided both when the potential at the junction of the measuring ionisation chamber 1 and a resistance element such as a reference chamber 8 exceeds an upper threshold and falls below a lower threshold, i.e. both when the potential drop across the measuring chamber 1 increases above a first pre-set value due to fire detection or fall in insulation resistance of the reference chamber and when the potential drop across chamber 1 falls below a second preset value due to a fall in the insulation resistance of chamber 1. As shown, Fig. 4, a pair of complementary F.E.T.'s 10, 11 have their gates connected to the junction, one transistor firing when the junction potential exceeds the upper threshold and the other transistor firing when said potential falls below the lower threshold to fire a SCS 17 via its two control electrodes 17a, 17b to energize the alarm relay 18. Other arrangements utilizing a pair of complementary F. E. T.'s are described with reference to Figs.3, 5 and 6 (not shown). In alternatives, a pair of similar F. E. T.'s are utilized, Fig. 7 (not shown), a single F.E.T. is utilized, Fig. 8 (not shown), a cold cathode  tube having two discharge paths is utilized, Fig. 2 (not shown), and a cold cathode tube is  connected across both the chambers 1 and 8, the grid being connected to the junction, and a discharge tube is connected across the chamber 8, Fig. 1 (not shown). As shown in Fig. 9, the F.E.T.'s 44 and 45 control a transistor 46 thereby providing a selfholding circuit. In a modification, Fig. 10 (not shown), a transistor (53) has its collector emitter path connected across the resistor 50, the base of the transistor (53) being connected to a voltage divider connected across the resistor 47 and the drain electrode of the F.E.T. 44. Instead of providing the same alarm signal for fire detection and insulation resistance breakdown, separate signals can be provided, Figs. 11-13 (not shown), Fig. 11 corresponding to Fig. 4, Fig. 12 corresponding to Fig. 9, and Fig.13 corresponding to Fig. 10. The fire alarm signal may be a D.C. signal, and the insulation resistance breakdown alarm signal may be an A. C. signal or a repeatedly interrupted D. C. signal, said signal being transmitted to a central station either over the power supply lines, in coded form, or by radio means.

Abstract: 1,118,633. Valve oscillating circuits. TRAK MICROWAVE CORP. 19 July, 1965, No. 30693/65. Heading H3F. [Also in Division H1] The invention relates to a microwave oscillator of the type comprising a valve 12 mounted coaxially within one end of, and with its cathode ring 14 connected to a tubular outer cavity 10, the anode 16 being connected to a coaxial inner conductor 32. A tubular member 24 is connected to the grid ring 15, being disposed coaxially between the outer cavity 10 and inner conductor 32 so as to produce grid-anode and grid-cathode cavities, but being limited in length so that an anode-cathode cavity occurs beyond it. According to the invention, the inner conductor 32 is terminated at its end remote from the anode by means of a quarter-wave choke comprising a coaxial sleeve 42, separated from conductor 32 by means of a tubular insulating member 49. The sleeve 42 terminates in a radial flange 43 which connects it to, and seals the outer cavity 10; the assembly is held together by an inner rod 36, the outer end of which forms an H.T. terminal 38 and bears a flange 37 separated from radial flange 43 by an insulating washer 57. Rod 36 is threaded at its end for engagement with an inner threaded portion of the bore in anode member 32; beyond this threaded portion the rod 36 is of reduced diameter, leaving a cavity 30 between it and anode member 32, so there is formed with the latter an additional quarterwave choke short-circuited at the end 35 and in series with the quarter-wave choke formed between sleeve 42 and the outside of anode member 32. Tuning is performed by means of an adjustable screw 61 projecting through the outer cavity wall into the anode-cathode cavity. Temperature compensation is performed by bi-metallic strips 64 which are riveted to radial flange 43. The tubular member 24 is located in the outer cavity 10 by means of insulating screws 28 tapped into the cavity wall.
