Title: Electric switches
IPC: F24C3/10
Filed: 1973-10-23
Abstract: 1469931 Ignition systems LICON ELECTRONICS Ltd 22 Oct 1974 [23 Oct 1973] 49303/73 Heading F1B [Also in Division H1] An arrangement for producing ignition of gas burners of a gas cooker or re-ignition in the event of flame failure uses switches S1 (see Division H1) coupled to respective tap spindles such that their contacts are closed when the associated valve is opened. Capacitor Cl is charged via diode D1 and is connected to the primary of spark transformer T2 via a thyristor SCR1. Each switch S is connected via a resistor Rl or R2 to an associated capacitor C2 in parallel with a respective secondary winding of transformer T2 and a series spark gap in an associated burner flame path. Each capacitor C2 is coupled to the gate of SCR 1 via a respective neon V1. When a switch S1 is closed the associated capacitor C2 is charged to a voltage which breaks down its neon V1, fires SCR1 and thus applies pulses to the transformer T2 until the burner is ignited, whereupon the spark gap resistance drops and the voltage on C2 is insufficient for neon V1 to conduct and pulsing ceases. Should the flame go out the spark gap resistance increases and the neon V1 fires SCR1 until ignition is re-established.

Abstract: 1,218,377. Inhibiting auto-oxidation; purifying cumene. TEXACO DEVELOPMENT CORP. 30 Oct., 1968, No. 51417/68. Heading C5E. The auto-oxidation of aromatic compounds of formula where R 1  is hydrogen, straight-chain C 1-3  alkyl or and R 2  and R 3  are straight-chain C 1-3  alkyl, which compounds contain trace amounts of corresponding hydroperoxide, is inhibited by contact at ambient temperature with a heterogeneous acidic catalyst in sufficient quantity to maintain the Acid Wash Colour of said compounds below 2. The hydroperoxide is cleaved to form a phenol which then acts as an inhibitor. Suitable acidic catalysts include alumina, bauxite, silica gel, polyphosphoric acid on kieselguhr, acidic molecular sieves and sulphonic acid type cation exchange resins. The compounds may be continuously circulated through a bed of the catalyst. The process is particularly applicable to cumene, which may also be improved from an AWC above 2 to one below 2 by contact with silica gel.

Abstract: 1,122,109. Filter. A. MIGULE and H. BURDE. 17 Nov., 1966 [9 March, 1966], No. 51613/66. Heading BID. A filtering apparatus comprises a rigid column of filter plates resiliently rotatably mounted in a casing in such manner that the said column of filter plates can perform rotary oscillations in relation to the casing. The plates when coated with filter cake may be oscillated at or near their natural frequency to remove the cake. In Fig. 1 the oscillation is effected when required by electromagnets 10 via bar 9, rigid bar 8, cap 7 and tube 12 to which the plates are attached. Cap 7 is mounted in elastically deformable steel or brass tube 6 which is itself rigidly attached to the casing. The casing 1 is supported on rubber cushions 3 so that complementary vibrations are induced in the casing to shake removed filter cake towards outlet pipe 21. Fluid may be withdrawn from the filter pipe 27 prior to the oscillations. Filtered fluid passes up passages (15) (Fig. 3 not shown) in the centre of the plates to vacuum pipe 18, which pipe has a flexible section 19. In the embodiments of Figs. 4 and 6 (not shown) oscillation of the plates is effected by oscillating the casing, antiphase oscillation being produced in Fig. 6 in which the casing is freely rotatably mounted in bearings (40, 41).

Abstract: 1,194,580. Automatic temperature control systems. ALEX FRIEDMANN K.G. Nov. 14, 1967 [Dec. 2, 1966], No.51730/67. Heading G3R. In a method of air conditioning passenger compartments particularly of railway trains, a measured temperature is compared with determined upper, intermediate, and lower temperature references such that at the upper temperature a cooling unit is prepared for operation and a heating unit disabled, at the lower temperature a heating unit is prepared and a cooling unit disabled, the output of either unit at any one time being controlled as a function of the measured temperature in relation to the intermediate reference. The heating and cooling units may be subdivided and one or more parts introduced in turn with a time delay. A temperature detector 7 controls a relay 10 operating contacts 10 1  and hence a relay 12 controlling a heating unit (not shown). As the temperature rises another detector operates another relay 11 closing contacts 11 1  which through already closed contacts 10 2  energizes a relay 15 which is held over its own contacts 15 2  contacts 15 1  disabling the relay 12, and contacts 15 3  energizing through contacts 10 3  a relay 16 which prepares a portion of a cooling unit. Simultaneously a timing relay 18 2  is energized which after a determined delay opens its own contacts 18 1  and closes contacts 18 2  energizing a relay 17 preparing a second portion of the cooling unit. The cooling unit is then controlled by detector 7 until a low temperature is sensed by a detector 6 when relay 9 is de-energized, opening contacts 9 1  which through relay 15 disconnects the cooling unit and prepares the heating circuit through contacts 15 1 . A high temperature safety cut out 13 may be provided, and a thermostatic switch 14 responsive to low outside temperature may disable the cooling circuit.

A synthetic plastics building brick has at least one re-entrant groove to interlock with correspondingly shaped tenons or rods of other building elements. The cross-section of the groove varies along its length so that an inserted rod of constant cross-section can move freely in the wider cylindrical outside part but is held by friction when moved further in to the inner, narrower, tapering part. The brick may be hinged in two parts 1, 2 in Figures 1 and 2, each part having at least one groove 6, 7 extending longitudinally from its free end face to near the hinge 3. Another brick 11 (not shown) has one groove 14-18 extending, longitudinally between the two end faces, wider at its two ends 15, 16 and narrower in the region 14 of the central transverse axis of the brick. Tenons such as 9 can engage the groove since the groove width remains unaltered in the tapering portion, so that other elements than rods 8 can be attached to the brick 1, 2, 11.
