Title: Improvements in rheostats
IPC: H01C10/32
Filed: 1925-04-30
Abstract: 250,766. Sterling Telephone & Electric Co., Ltd., and Tiller, P. A. April 30,1925. Contacts. - Switch-arms co-operating with the contacts of variable inductances &c. or movable across the wire windings of filament resistances, potentiometers &c. comprise a resilient metal strip 5 doubled upon itself with the overlying parts 6, 7 at a short distance apart and both apertured to receive an operating spindle 4 of non-circular cross-section, the apertures being in line to receive the spindle 4 when the arm is stressed. The parts 6, 7 may comprise enlargements in the strip at one end and near its centre, and the ends of the strip may be stiffened by bending up at right-angles at the sides 9. The parts 6, 7 are moved towards or away from each other in introducing the spindle 4 and grip the spindle due to the resilience of the strip 5 and to the pressure of its end 9 on the wire winding. The spindle may have a flat at one side and may be notched at 14 to position the part 6. The Provisional Specification describes bending the enlarged end of the strip to form a grip.

Abstract: 592,369. Carbon papers. CREED & CO., Ltd. May 4, 1945, No. 11349. Convention date, May 13, 1944. [Class 100 (iv)] [Also in Groups VIII and XV] A telegram form for use when recording secret messages in a recording or receiving apparatus comprises two superposed sheets 10, 11 having areas A, A<1> and B, B<1> for the address and message respectively, secured together so as to conceal the inner message area, one of the sheets being treated with a marking- material so that a recording of the message will be produced on the inner surface of one of the sheets. Instead of sheets, tapes may be used. As shown, the composite sheet is formed by folding a single sheet at 12, the areas A, B of the sheet 11 being coated with transfer material, and the sheet 10 having adhesive strips 16, e.g., of polyvinyl alcohol, by which the sheets are secured together. The address and message is imprinted on the outside of the sheet 11 by means which leave no mark on the sheet 11 but because of the transfer material cause the matter to be inscribed on the inner surface of the sheet B. Perforations 15 may be provided around the area A so that it can be removed to expose the address on the part A<1>. Alternatively, the sheets 10, 11 may be secured together only up to the line a, a<1>, so that the upper portion of the sheet 11 may be folded back. The form has to be cut or torn open for the message to be read, and for this purpose, may be perforated at 12 and 18. The forms may be made as a continuous web of two layers secured together as set out above and which, after the recording, are severed and delivered to the attendant. When in tape form, the strips are fastened together along narrow margins adjacent to their edges and transversely to conceal the message. The receiving apparatus may be of the type employing a percussion stylus, or typewheel or typebar machines with a hammer for causing the impression may be used, the ink-ribbon being omitted.

Title: Control apparatus for burners
IPC: F23N5/02
Filed: 1974-03-20
Abstract: 1437698 Controlling burners SIOUX STEAM CLEANER CORP 20 March 1974 [29 May 1973] 12339/74 Heading F4T and F4F A burner apparatus 10, Fig. 2, for heating water is turned on in stages comprising establishing a spark at igniter 14 if a plurality of operating conditions are within predetermined ranges, allowing fuel flow to jet 16 to form a low flame when a sensor 40 detects a spark, and allowing fuel flow to jet 18 to form a higher flame when a sensor 42 detects a flame at jet 16. The control circuitry, Fig. 1, comprises switches 70, 72, 74 in series with power source 78 and the primary winding of ignition transformer 76 so that the latter can only be energized when the switches provide continuity. This state exists if a sensor 11 detects that the temperature of the water to be heated is less than, e.g. 205‹ F., a sensor 56 detects suitable water flow in pipe 54, and a sensor 60 detects suitable combustion air pressure. Energization of transformer 76 causes sparking at igniter 14. Sensor 40 thus energizes relay 80 causing the latter to move downwardly to supply current through line 141 to valve solenoid 36. Valve 32 therefore opens to supply liquid fuel through line 24 to form a low flame at jet 16. The flame sensor 42 consequently energizes relay 90 to supply current through line 145 to valve solenoid 38, providing switch 92 has been closed by sensor 13 detecting a water temperature below, e.g. 195‹ F. Valve 34 thus opens to supply fuel through line 26 to form a higher flame at jet 18. Indicator circuitry (Fig. 3, not shown) includes relays (100-105) and indicator lights (110-115) to indicate completion of the different turn-on stages or the occurrence of unsuitable operating conditions.
