Title: Improvements in electric heating apparatus and control arrangements therefor
IPC: G05D23/24
Filed: 1956-07-13
Abstract: 827,459. Switching systems for consumption apparatus; automatic temperature-control systems. GENERAL ELECTRIC CO. July 13, 1956 [July 13, 1955], No. 21750/56. Class 38 (4). Electric heating apparatus comprising an electric hotplate adapted to support a vessel to be heated is characterized in that the control means for the hotplate includes both manuallyoperated and automatically operated control devices, the automatic control means including a temperature-sensing element which contacts the vessel to be heated in heat-exchanging relationship thereby to govern the temperature range over which the hotplate operates which range can be varied by means of manuallyoperated switching devices. An electric cooking range includes a hotplate 16 having a heating element 25 and a temperature-sensing element 27, the arrangement being such that when a cooking vessel is placed on the hotplate 16 it rests on the element 25, the temperaturesensing element 27 being kept in contact with the bottom of the cooking vessel by means of a spring 46 so that changes in the temperature in the vessel affect the temperature of an aluminium button 45 which houses a temperaturesensitive resistor R6. Manual control of the two halves 25a, 25b of the heating element is effected by means of push-buttons in a control switch 21, one of these push-buttons however being arranged to prepare the system for automatic operation. Under automatic control the cyclic switching on and off of the heating element 25a, 25b is effected by the spring sets of an electromagnetic relay 110 in response to the degree of energization of its operating coil 112 connected in the anode circuit of an electronic valve 130, such that as the hotplate temperature rises the impedance of the temperature-sensitive resistor R6 falls to increase the bias on the grid of the valve 130 so that the current through it and the relay winding 112 falls to cause the relay to drop out and disconnect the heating element 25. The relay picks up again when the hotplate temperature falls to increase the impedance of the resistor R6. Various temperature ranges over which the hotplate may operate are set by means of a push-button device 21A which places requisite resistors R11, R12, R13, R15 in the grid circuit of the valve 130 whilst variations within these ranges, except the fixed temperature range, can be made by a rotary control device 21B which places variable amounts of the resistors R14, R16 in the grid circuit of the valve. Specification 144,767, [Class 39 (iii)], is referred to.

Abstract: 406,205. Rolling. SCHLOEMANN AKT.-GES., 13, Steinstrasse, and GASSEN, J., 34, D³sseldorferstrasse, Oberkassel, both in D³sseldorf, Germany. Aug. 3, 1933, No. 21807. [Class 83 (iv).] The mandrel 4 of a pilger mill is rotated, between the strokes, a constant amount independent of the length of stroke, by a cam 25 on the rolls which switches on a motor 14 to rotate the mandrel 4, a cam 15 on the gearing switching off the motor 14 after rotation. The motor 11 drives through gears 12, 13, a crank 10 which actuates a pawl and ratchet wheel 6 to rotate the squared spindle 5, on which the piston hub 22 oscillates during working, so that the piston 21 and its mandrel 4 are rotated. The carriage is advanced an adjustable amount after each stroke, or every second stroke, by rotating the spindle 17 in the nut 18, of the carriage, this rotation being obtained from the rotation of the roll by gearing (e.g. 2 to 1 gearing).

Title: Treatment of sewage
IPC: C02F1/72
Filed: 1972-05-10
Abstract: 1396878 Treating sewage SANITAS CO Ltd 10 Aug 1972 [10 Aug 1971 10 May 1972] 37514/71 and 21883/72 Heading C1C A method of treating sewage comprises the steps of (a) flushing sewage from a plurality of receivers by means of a flushing liquid thus forming a mixture of liquid and sewage, (b) separating the mixture into a part which has a high content of solid matter and a part which has a high content of liquid, (c) separating solid matter from the part with the high liquid content, (d) maintaining a chemical composition in the liquid resulting from step (c) such that the liquid is disinfectant and deodorant, (e) maintaining a bleaching action in the liquid resulting from step (c) so as to have a decolorizing effect, (f) using the liquid resulting from step (c) as flushing liquid for repetition of step (a), (g) subjecting the part with the high solid content resulting from step (b) to mechanical reduction of the size of the pieces of the solid matter, and (h) thereafter holding that part in a place of storage so that substantially all the solid matter is exposed to the chemical content of the liquid constituent of that part and is thereby broken down, dispersed, sterilized and deodorized. The flushing liquid may be a weak caustic alkali solution. The bleaching action may be produced therein by the addition to the liquid of a water-soluble chlorinating agent, e.g. calcium hypochlorite. Alternatively, sodium chloride may be present in the liquid and the bleaching action is produced by electrolysis of the liquid. The method may be carried out in the apparatus shown in Fig. 1 wherein sewage from urinals &c. 4 is flushed with liquid from pipe 6 into tank 2. This tank comprises comcompartment 30 separated by screen 34 from compartment 32, this latter compartment being separated by weir 38 from compartment 36 and beyond the screen 42, compartment 40. This arrangement of compartment &c. is such that the liquid sewage mixture flowing into tank 2 is separated by the screen 34 so that a high solids content part collects in 30, and a high liquids content part flows into the compartment 36. The former part passes to macerator 60, and thence via pump 62 to storage tank 64. Solids in the high liquid content part either settle in tank 36 or are removed by screen 42. Liquid in compartment 40 is recycled to tank 28 for further flushing use. The content of caustic alkali in the liquid in tank 2 may be maintained at a desired level by adding portions of the chemical from tank 72. Further bleaching agent may be contained in basket 48. In an alternative arrangement (Fig. 3, not shown), an electrolytic cell is positioned above the separator tank so that chlorine is produced by the electrolysis of sodium chloride in the liquid, and hence decolorisation achieved.

Aug. 18, 1933, No. 23085. Convention date, Aug. 18, 1932. [Class 83 (iv).] An arc-welding apparatus, particularly for welding tubes into boiler-tube sheets or transformer tanks, comprises means for directing a welding arc in a predetermined closed path, means for swinging the arc away from the path after the weld has been lapped upon itself a predetermined amount and means for interrupting the welding arc after it has been swung away from the closed path. Fusible metal electrodes or carbon or other non-consuming electrodes may be used. The electrode holder 38 is carried by a table 20, which is rotated by a motor through a gear box 25, hand released bevel gear and spur gear 21, in a ring 11 adjustable on guide rods 12 on the machine frame. Electromagnets 15 provided with shields 16 fix the machine on the sheet 18 and adjustable rods 17 position the welding head over the tubes 19. From the table extends a slotted sleeve 29 in which is spring-mounted a spindle 28 to which is fixed the shank of a rotatably mounted centering head 30. The spindle may be raised by rack 34 and pinion and secured in position by a screw 36. The electrode holder is pivoted at 40 on a collar 39 on the spindle and kept inclined towards the axis by a spring 41, the angular position being adjusted by a screw 42, which is carried by a lever 43 pivoted at 44 to the holder. The lever 43 is normally pressed by the spring against the outer end of a slot 45 in the table. Electrode wire may be fed as described in Specification 184,141, [Class 83 (iv), Metals, Working], through a flexible tube secured to the framing, and through an inclined conduit 48 secured to the table so that the upper end is substantially in alignment with the axis of the table. The holder is electrically connected to a slip ring 50 fixed to the table, which co-operates with brushes 51 on a segment 52 connected to the source of supply. To the ring are pivoted respectively at 57 and 58 a pair of interengaging levers 54, 55, normally held by a spring 59 in contact with a stop 60. By closing switch 62, the table starts rotating in an anti-clockwise direction and the welding current put in to effect the weld. When a lever 56 carried by the table engages the lever 54 the cam end 61 of the lever 55 is thrown into the dotted position into the path of the lever 43, which upon engagement therewith is rocked about its pivot 44 to move the electrode away from the tube. When the lever 56 reaches the dotted position the switch 62 is opened by the lever 54 to cut off the current. The table coasts along a further small distance during which the levers are automatically reset.
