Abstract: 416,697. Engine valve - gear. NICHOLS; T. W., 63, Capel Road, Forest Gate, London. June 19, 1933, No. 17387. [Class 122 (ii).] In a combined fluid-actuated and mechanical valve-gear for a pump or fluid-pressure motor, wherein a mechanically-operated, flat-slide, cut-off valve functions as an auxiliary distributing-valve to the main-piston valve, the cut-off valve controls the main admission only, the main exhaust being controlled by the main piston valve. A false exhaust port is arranged in the cut-off valve face to effect balance,and the ports are arranged symmetrically, so that the valve may be inserted upside down without affecting the working of the pump or motor. The steam ports a<3> are controlled by the cut-off valve b, and the exhaust ports a<5> by the main valve a<1>. Steam at cylinder pressure is supplied to ports h, h<1> in the cut-off valve seat through passages e, f<1> ,e<1>, e<2>, f<2>. Auxiliary steam ports c<1>, c<2> lead to the ends of the main-valve chamber, and ports d<1>, d<2>, which function as steam and exhaust ports, also connect the ends of the valve chamber with the seat in the casing. These ports are controlled by the ports h<1>, h<2>, and the ports d<1>, d<2> are also controlled by exhaust ports p<1>, p<2>, which communicate with a central cavity through a port n designed to effect balance and which is connected to the main exhaust by a port m. The pressure of steam in the ports h, h<1> balances the pressure on the auxiliary piston g. Steam to complete the stroke of the main piston is supplied to the cylinder after the ports a<3> have been closed by the valve b. This is effected through a groove r in valve b and recess l in disc g which communicates with supply ports v<1>, v<2> in valve b. The steam may be supplied to the grooves, h, h<1> through a dual-acting steam stop valve of the kind described in Specification 3023/15, [Class 122 (ii)].

Title: Improvements in and relating to temperature control devices for electrically heated utensils
IPC: H05B1/02
Filed: 1956-06-06
Abstract: 819,740. Electric heating. JACKSON ELECTRIC STOVE CO Ltd., (Fischer, K.). June 6, 1956, No. 17508/56. Class 39(3) [Also in Group XXXVII] The temperature of the contents of an electrically heated cooking utensil is limited by a device removably disposed on the lid of the saucepan and comprising a switch mechanism operable by a temperature sensitive element exposed to steam escaping from the contents. As shown, a device, supported in the middle of a saucepan lid by rests 13 in a recess 11 having an opening 12 through which steam can escape, comprises a casing 1 closed on the underside by a base 2 and on the top by a lid 3, and having a lead 5 which connects, by wires 51, 52, the saucepan heating means to terminals (not shown) on a switch inside the casing 1. The base 2 is formed as a temperature sensitive element comprising a corrugated membrane arrangement, the strong outer wall 30 and a weaker inner wall 31 of which define a small inner chamber which is partly filled with a liquid, e.g. alcohol, having a boiling point of approximately 176‹F. An insulating ring 33 built into the casing 1 carries a fixed contact 46 co-operating with a movable contact 45 mounted on a snap action switch comprising a leaf spring, also mounted on the ring 33, with two portions 35 and one portion 36 which is bent in order that one end may be fixed in a groove 39 of a bush 40 mounted on a lever 41, so stressing the portion 35 that contacts 45 and 46 remain together. On heating, steam escaping through the hole 12 impinges on the temperature sensitive base 2 and vaporizes the alcohol in its inner chamber, causing the inner wall 31 to bend and urge a pressure button 49 upwards against a lever 48 which in turn raises the bush 40 so that the bent portion 36 is carried upwards beyond the plane of the portions 35, the resultant pressure causing the contacts 45, 46 to separate and switch off the heating element. Subsequent cooling causes the device to switch on again, to keep the contents of the saucepan at or about boiling point. The operating temperature may be adjusted by means of a screw 50 which alters the pressure on lever 48. The device may be supported on the lid so that it projects into the saucepan, may rest on struts on the lid, or may be held in position by a spring clip on the lid (Figs. 2, 5 and 7 not shown).
