Title: Improvements relating to edging strips for roof coverings
IPC: E04D13/15
Filed: 1961-05-23
Abstract: 957,059. Edging strip for covered roofs. K. J. CLIFT. May 1, 1962 [May 23, 1961; June 1, 1961], Nos. 18492/61 and 19758/61. Heading E1V. An edging strip for a layer or layers of weatherproof roof covering 16 laid over a roof surface 12 of a building comprises an open channel the inner side wall 2 of which is provided with a flange 4 adapted to seat upon, and to be fixed to, the roof surface, whereby the roof covering may be directed down into the open channel. Ribs 8 in the channel oppose upward seepage of moisture due to capillary attraction and also serve as locking projections which key with the roof covering 16. Strips laid end-to-end may be interconnected by a short bar 7 inserted endwise into V-sectioned keyways 11 in the adjacent strips. A masking plate 19 serves to cover an expansion gap left between such adjacent strips. The covering 16 may be asphalt, as shown in Fig. 7, but may also be of bituminous felt, in which case the outer wall 3 of the channel extends only slightly above the level of the flange 4, and the seal within the channel is completed by a bituminous filling as in Fig. 9 (not shown). In the examples shown, the flange 4 is secured over a felt underlay 13.

Title: Solid State Oven Temperature Control.
IPC: G05D23/24
Filed: 1967-04-24
Abstract: 1,178,417. Automatic temperature control systems. GENERAL ELECTRIC CO. April 24, 1967 [May 26, 1966], No. 18730/67. Heading G3R. The heating unit 12 of a self-cleaning electric oven is controlled by the circuit shown in which the contacts 10 of a hot wire relay 11 are respectively closed or opened by the continuous energization or de-energization of a heated wire actuator 13, which energization is dependent on the action of a unijunction transistor 17 and a silicon controlled rectifier 16 whose conductivities are controlled by a voltage divider including a temperature responsive resistor 23 sensitive to the oven temperature. During cooking operations a switch 42 is set to connect the resistor 23 to resistors 24, 25 and the temperature is controlled at a value set by adjustment (through a control knob) of the resistor 24. For heat cleaning the switch 42 is set to connect resistor 23 to an impedance network 28 and the temperature is controlled at a value determined by the setting of a calibrating resistor 30 and by the other members 31, 32, 33 of the network 28. The heat generated by a resistor 34, which is in parallel with the unit 12 but thermally isolated therefrom and from the oven, is indicative of the average power delivered to the unit 12. By suitable choice of the resistor 31, of the resistor 32 which has a negative temperature co-efficient of resistance and is responsive to the ambient temperature of resistor 33, and of the resistor 33 which has a positive temperature co-efficient of resistance and is responsive to the heat generated by the resistor 34, the magnitude of the combination 31, 32, 33 is arranged to be indicative solely of the average power delivered to the unit 12. The design of the network 28 also ensures that the final heat cleaning temperature is reached without overshoot, and the behaviour of the circuit is described for a typical heat cleaning operation, Fig. 3 (not shown). Temperature control at the cooking or the heatcleaning temperature is produced by the members 11, 16, 17 which are arranged so that the conduction of transistor 17 during a positive half cycle of the supply V 0  fires the controlled rectifier 16 to (fully) energize the actuator 13 and close contacts 10, the latter remaining closed during the-succeeding negative half cycle due to the mechanical inertia of the relay 11. The functioning of the circuit for a typical cooking operation is described, Fig. 2 (not shown). Rapid cycling of the contacts 10 is prevented by the self-heating of the resistor 23 which occurs during the whole of each positive half cycle when the transistor 17 does not conduct. The controlled rectifier 16 may be replaced by a pair of cascaded transistors, Fig. 4 (not shown).

Filed: 1951-08-14
Abstract: 682,658. Electrode boilers.. EATON, M. Aug. 14 1951 [Aug. 24, 1950], No. 19133/51. Class 39(iii) An electrode boiler comprises an electrode 12, normally partly submerged in water in a vessel 11, means for raising or lowering the water level in the vessel 11, and a water circulation pump 50 having its inlet communicating with the water below the minimum operating level thereof and its outlet communicating with a spout 54 immediately beneath the electrode 12. A jet of water is hence forced up into contact with the electrode 12. The level of water in the vessel may be regulated by automatic means as described in U.S. Specification 2,453,210, to which arrangement the pipes 20, 21 and 23 relate, or by alternative means, e.g. as described in Specification 193,405, [Class 39(iii)]. Boiler feed water is supplied from a pipe 57 either to a distributor 53, where it mixes with the water from the pump 50, or to the inlet of the pump 50, steam passing off at 15. The velocity of the jet may be regulated by a valve 56 on the outlet side of the pump 50, or by providing a variable speed drive for the pump 50. A shield 13 acts as the other terminal of the current supply, and the spout 54, which has a bored cap 55, has an earth connection 58 to the boiler shell. Alternatively the spout 54 may be of insulating material, e.g. hard glass. The electrode 12 is connected to a three phase supply, the other two electrodes being either in the same or separate boiler vessels. In the second case, the shield 13 surrounds the three electrodes, each of which has beneath it a spout communicating with the pump.

Title: Improved method of producing an opaque covering layer on a carrier comprising a light-transmitting recording layer suitable for recording sound or like oscillations
IPC: G11B11/00
Filed: 1937-07-13
Abstract: 483,898. Optical sound - records. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. July 13, 1937, No. 19440. Convention date, July 13, 1936. [Class 40 (ii)] Relates to the production of sound-records of the kind having an opaque layer 3, and a light transmitting recording layer 4 which may be on a supporting layer 5 and is cut by a chisel 1 to represent the sound oscillations. According to the invention, an opaque covering layer is formed before or after recording by adding to the surface of the record, one or more substances which in co-operation with one or more colloidally dispersed substances present in the recording layer or in a covering layer applied thereto or constituting the recording or covering layer produce a coloured compound in a superficial zone of the recording layer or in the covering layer. In one example, the recording layer, is made of gelatine containing lead acetate, and its surface is treated with an aqueous solution of ammonium sulphide forming an opaque layer of lead sulphide. Alternatively, the lead acetate is painted on the surface of the recording layer instead of being incorporated therein. In a modification, the lead acetate is incorporated in a separate coating. The treatment with ammonium sulphide may be made before or after recording. Various other substances may be used, for example : copper salts, mercurous salts, or nickel salts may be used instead of lead salts, and alkaline sulphides or hydrogen sulphide used instead of ammonium sulphide ; mercury nitrate may be treated with ammonia solution or wet ammonia gas ; potassium ferrocyanide may be treated with ferric salt solution, indigo white may be treated with oxidizing solution or oxygen gas or air to produce indigo blue ; or after recording the recording layer of gelatine may be treated with alkaline copper sulphate which yields a blueish-reddish violet compound, or with a diazo-benzene sulphonic acid solution, which couples with the amino-acid in the gelatine and is subsequently painted with a solution of soda.
