Abstract: 863,625. Electric thermal storage space heaters. GENERAL ELECTRIC CO. Ltd. May 4, 1959 [May 9, 1958], No. 14909/58. Class 39(3). In an electric thermal storage space heater comprising a casing 1 incorporating heat storage material, e.g. concrete blocks 3, and electric heating means, e.g. a resistance wire 4 wound round a former 5, at least one side of the casing is constituted by inner and outer walls 7, 8 separated by an air vent 9 which is closed at its upper end by a grille 11 or the like which prevents ingress of inflammable material. A radiation screen is provided between walls 7, 8 to minimize the heating of the outer wall. As shown, the space between the blocks 3 and casing 1 is filled with heat insulating material 6. The outer wall 8 is cut away at 10 to provide clearance for a skirting board and the bottom of the air vent 9 communicates with an air space 12 beneath the heater. Holes 19 in wall 7 allow ventilating air to circulate through the terminal box behind cover 17. A wire guard 18 extends across the top and partway down the front of the heater.

Title: Improvements in and relating to control circuits for relay devices
IPC: H04B1/46
Filed: 1947-06-05
Abstract: 636,900. Valve relay circuits. BRITISH TELECOMMUNICATIONS RESEARCH, Ltd., and HOLLOWAY, D. G. June 5, 1947, No. 14935. [Class 40 (vi)] The operation of a fast-operate, slow release relay of the mechanical or electronic type is controlled by means comprising a condenser which is charged rapidly by the actuating voltage and which discharges rapidly to an intermediate value and thereafter relatively slowly. The release time is thus substantially independent of the magnitude of the actuating voltage. The Figure shows a voice-operated relay in which the voice signals applied to transformer. 12 are rectified to produce a negative voltage across diode load 13 to cut off the anode current of the triode. Relay 16 in the anode circuit is adjusted to operate on a small reduction in current so that a fast response is obtained. When the signals cease the charge which has built up in.condenser 14 discharges relatively rapidly until the valve conducts when a large increase in the effective capacitance takes place and discharge continues at a slow rate.

Abstract: 1427912 Charge transfer delay circuits ITT INDUSTRIES Inc 5 April 1974 [6 April 1973 14 July 1973] 15238/74 Heading H3U In a bucket brigade delay circuit, frequency dependent attenuation is compensated by feeding the outputs from two consecutive stages of the same clock phase, 2n, 2n+2 to the inputs of a differential amplifier DV1 and coupling the amplifier output to one of the stages. The amplifier output may be capacitively coupled to the delay, or a current generator RSQ may produce a current proportional to the amplifier output which is directly coupled to the delay. Before coupling the amplifier output to the delay it may be delayed by passing it through a further bucket brigade delay EK4. Various modifications (not shown) are described namely: Fig. 1: basic circuit without current generator or further delay. Fig. 2: circuit of Fig. 1 including compensating delays (EK1, EK2). (These two circuits include a further amplifier DV2 which provides an output to cancel the D.C. level at the stages of the delay). Fig. 3: simple circuit without compensation for D.C. in which the amplifier output is fed to the stage (T 2n+3 ) from which one of the inputs are derived. Fig. 4: includes a circuit for varying the gain of the differential amplifier DV1 in dependence on variations in clock frequency.

Abstract: 1428022 Digital data stores PNEUMOTECH AG 30 March 1973 [30 March 1972 9 March 1973] 15339/73 Headings G4B and G4M A digital data storage device for use in a fluidoperated programming system comprises a plate formed with through-apertures, selectively blockable against fluid flow by balls, either the plate or the balls or both having at least their co-operating surface regions formed of elastically yieldable material so that the balls are resiliently held in the blocking positions. As shown, the plate is a laminate of an elastomer 3 and aluminium 1. The balls 9 are slightly larger than unstressed apertures 7 and may be inserted into the chosen apertures by a pusher when the plate is held in a jig, Fig. 3 (not shown). Instead of removing a ball when an aperture is to be unblocked, the ball may be moved to a larger portion of the aperture, where it is held and permits fluid flow through the aperture, Fig. 4 (not shown). The cross-section of the larger portion may be circular, with inwardly projecting ribs to hold the ball, or may be square, triangular or diamond shaped (Figs. 5A-5D). Alternatively, the larger portion may be such that the ball is fee to move therein (Figs. 6, 7); in these embodiments, when the ball is located in the larger portion (aperture unblocked) it coacts with the junction between the larger and smaller portion to provide a one-way valve preventing fluid flow in the direction contrary to the reading direction.

[Also in Group XIII] In a liquid cooler, liquid from troughs 9, fed from a tank 7, e.g. through pipes 8, overflows on to and streams down a series of stepped surfaces 1, which are spaced by sinuous passages for the upward flow of cooling air and each terminate in a substantially vertical wall with saw-teeth 2 on its lower edge, from which the water trickles and falls into a receptacle. The surfaces 1 are formed by tubes, as shown, L-sectioned strips, or a bent metal sheet. The stream of falling drops are collected by metal strips 11 with inclined surfaces leading into troughs 12, or in staggered rows of troughs. A current of cooling air from a fan 15 is directed upwardly in contact with the falling water by baffles 17. The Specification as open to inspection under Sect. 91, describes also apparatus, Fig. 7 (Cancelled), in which water overflows from a trough 21 on to a corrugated metal sheet 23. The trough may be inclined, or have corrugations of increasing depth from one edge to the other. To the outer end of each trough in the corrugated sheet there may be connected a downwardly-extending plate over which the water flows, or an inclined rod with downwardlyprojecting teeth. This subject-matter does not appear in the Specification as accepted.

In a pulse generating circuit in which a capacitor C 2 , or pulse-forming network, discharges periodically through a saturable reactor P 2  and primary winding W 1  of a transformer supplying a load from its secondary winding W 2 , minor output pulses due to current flowing in winding W 1  during the charging of capacitor C 2,  from capacitor C 1  through saturable reactor P 1 , are prevented by passing this charging current through a tertiary winding W 3  so that its ampere-turns are equal and opposite to those of the primary winding W 1 . In a modification (Fig. 2, not shown), winding W 1  may be rendered ineffective by passing the charging current through the primary winding of a transformer whose secondary winding is connected across winding W 1 . Undesired pulses may likewise be prevented from reaching subsequent stages in a cascade arrangement by connecting such a transformer across the input to those stages (Figs. 4, 6, not shown).
