Title: Improvements in or relating to cooking stoves or ranges
IPC: G05D23/02
Filed: 1936-04-14
Abstract: 478,193. Thermostats. STEVENS, A. H. (Estate Stove Co.) April 14, 1936, No. 34622/35. [Class 135] In a cooking-stove provided with a thermal element, which projects into the oven and is controlled by an external member carried by a front panel, the coupling of the control member 10 to the valve mechanism is disconnectible at a tongue and groove connection 110 by removal of the panel 112. The shaft 106 of the handle member 10 passes through a hole in the panel with some clearance, permitting connection in spite of inaccuracies in relative positioning of the parts. Rotation of the handle 10 first opens the cut-off plug valve 16, admitting gas from the manifold 20 to the thermally controlled valve 73 by a peripheral and an axial passage in the plug. Further rotation of the handle maintains the valve 16 open, and by gearing 99, 96, 95 and a screw-thread 58, sets the valve 73 by longitudinally adjusting the telescopic thermal element 60, the internal rod 65 of which is in contact with a pin 70 bearing against the spring-pressed valve 73 which regulates the flow of gas to the oven burner 86. A minimum flow of gas is provided when the valve 73 is closed, by means of an adjustable byepass. Indications on an indicator 118 are visible through an aperture 120 in the panel 112. The gear 99 may be slidably disengaged to enable the initial adjustment at assembly to be made, a screw 68 on the thermal element providing further adjustment.

Class 86 [Also in Group XXVI] In the control mechanism for fire fighting equipment described in Specification 702,609, wherein the water-valve link p and the foam compound valve link 12 are connected by the linkage shown so as to be operable in unison by a rod e, the relationship between the extent of opening of the two valves being adjustable by means of a manual control knob 4 which also opens and closes an air valve through a link 15, the connections to the engine throttle and to a manual output control lever are omitted, the rod e being connected instead to a piston f. Cylinder g is connected by pipe i to the pump intake pipe at a point downstream of the air, water and foam compound inlets so that the piston f is acted on by the vacuum at the pump intake, thereby varying the pump delivery in accordance with the demand. In a modification, the linkage between arm m and rod v is omitted, the rod v being connected instead to a further piston operated in the same way as piston f, so that the water and foam compound valves are controlled by separate pistons. Manual shut-off valves in the pipes connecting the two cylinders to the pump intake permit the water and foam compound valves to be brought into operation independently of one another.

Abstract: 1,053,753. Bending and tempering glass sheets. LIBBEY-OWENS-FORD GLASS CO. Sept. 4, 1963 [Sept. 14, 1962], No. 34923/63. Heading C1M [Also in Division B8] In a method of bending and tempering glass sheets the latter are moved along a predetermined path through a zone where they are heated to softening point, then advanced at a set speed to a set location in a bending zone where they are halted and pressure applied to the opposite surfaces to bend the sheet, the bent sheet is moved out of the bending zone and into a chilling zone at a speed relatively greater than the speed of entry into the bending zone, this speed being reduced to the first entry speed when the sheets have entered the chilling zone. A glass sheet 12 is passed on a conveyer 11 through a furnace 16 wherein it is heated to its softening point (Fig. 1, not shown). On leaving the heating zone the sheet is passed into a bending zone by means of entry roller conveyer 27 which is driven at the same speed as conveyer 11. The sheet is then passed on to rollers 91 of the bending zone at the end of which the leading edge of the sheet contacts the stop butt 119 of a device 29 which applies a brake 107 on a twospeed motor 96 driving rollers 91. The device 29 is lowered into position when the sheet is sensed to be approaching by means 28 e.g. photoelectric cell. In this arrested position the sheet is lifted vertically away from the rolls 91 by the complementary shaped lower mould half 25 being brought into contact with the upper mould half 24 and the sheet bent to the desired shape. The lower mould half 25 is raised by the actuation of a magnetic clutch starting a cam 63 which has a follower 73 fixed to a parallel links system attached to the lower mould half carriage 52. The cam 63 also determines the length of time bending pressure is applied. When the now bent sheet has been lowered on to the rollers 91 the motor system 96 is actuated to drive the rolls at a higher speed than the entry speed, the stop device 29 is raised to an inoperative position by piston and cylinder means 134, 135, and the bent sheet is advanced into the chilling zone between blowers 20, 21. The sheet is passed along take out rolls 112 which are driven by the same motor and at the same speed as rolls 91. When the sheet has entered the chilling area upon rolls 22a the driving speed is reduced to that of the entry speed from the heating zone A. The piston and cylinder means 134, 135 are then reversed and the stop device 29 is lowered to start a new sequence.

Abstract: 931,523. Pulse code modulation systems. NIPPON ELECTRIC CO. Ltd. Oct. 14, 1960 [Oct. 20, 1959], No. 35321/60. Class 40 (5). In a circuit for selecting regularly recurring synchronizing pulses from a train of random pulses, e.g. in a pulse code modulation system, the input pulse train is supplied to a pulse shaper 4, limiter 5, and differentiator 6 to produce trigger pulses driving a pulse generator 7 having a natural repetition frequency equal to the repetition frequency of the synchronizing pulses. The output of the generator 7 is fed back via a phase inverter 8 and gate 9 to stop the generator when the gate is open. The input pulse train after shaping at 4 is also fed via a phase inverter 11 to the gate 9 so that when a pulse appears at both inputs of the gate it is closed. In this condition the generator continues to operate. If the generator output pulse appears at a time when there is no corresponding pulse in the input pulse train the generator is stopped by the resulting negative feedback until the succeeding input pulse arrives, the process being repeated until the generator is in synchronism with the synchronizing pulses.

Abstract: 820,104. Forcing liquids by gaseous pressure. KIRALY, J. L. Nov. 14, 1957, No. 35492/57. Class 102(2). [Also in Group XVIII] A valve controlling the discharge of a measured quantity of fluid under pressure from a container 10 comprises a sleeve 14 mounted in the neck of the container against a gasket 17, a hollow stem 26 passing through the gasket into a measuring cup 21 having a reduced portion 28 at its lower end and a spray cap 34 fixed on the hollow stem. Initial downward movement of the cap and hollow stem causes a neck 32 on the stem to seat on a ring 33 and seal the measuring cup from the stem and further movement depresses the cup against the action of a spring 23 and away from the gasket 17 so that fluid from the container can flow up a tube 19 and into the container through passages formed by ribs 20 on the sleeve 14. On release of the spray cap, the spring 23 moves the cup up to seal against the gasket 17 and the gasket which has been flexed downwards, shifts the stem further upwards to allow the contents of the cup to discharge past the ring 33 and up the stem 26. To provide for continuous flow, the neck 32 and ring 33 may have a non-circular configuration so that they do not mate when the stem is turned through 90 degrees ; rotation of the measuring cup is prevented by projections engaging the ribs 20. In a modification, the lower end of the stem 26 may be internally bevelled so that it seals against a cone extending up from the bottom of the cup or, as shown in Fig. 10, a spring- loaded valve 116 is provided which, on downward movement of the stem, is first engaged by a bevel 125 to seal off the stem and is then disengaged from a seat 114 to allow the measuring cup to fill. Collars may be placed in the measuring cup in order to vary the quantity dispensed. To improve the atomization, a plug with a spiral groove may be fitted in the chamber 36 of the cap shown in Fig. 1 or an annular groove 131 may communicate with the interior of the stem through the passage 129 shown in Fig. 10 or through a hole diametrically opposite the spray aperture 127. For filling the container, a filling head may engage over the hollow stem 26 or, in the absence of the stem, bear directly on the part of the container neck above the gasket 17.
