Filed: 1951-03-06
Abstract: 701,117. Gas turbine plant. LUCAS (INDUSTRIES), Ltd., J. Feb. 8, 1952 [March 6, 1951], No. 5383/51. Class 110 (3). [Also in Group XII] Liquid fuel combustion apparatus comprises a fuel pump, a non-return valve controlling the inlet to the pump, a combustion chamber into which the pump discharges through a valve spring loaded to the closed position and a fuel chamber consisting of a cylinder and a spring loaded piston, one end of the cylinder being connected to the combustion chamber and the other end to the inlet side of the pump. The combustion apparatus shown, which is suitable for burning liquid fuel such as propyl nitrate for an engine-starting turbine, consists of a combustion chamber i and a fuel chamber f containing a spring-loaded piston g. Fuel from the receptacle d passes through a non-return valve e, spring loaded to the open position, to an electrically driven rotary pump a which discharges through a valve r, spring loaded to the closed position, to the fuel discharge nozzle p. When the apparatus is shut down, the valve e is open and fuel flows from the receptacle d to the chamber f. Starting of the pump a causes the piston n of an accumulator to be pushed back and when a predetermined pressure is reached the valve r is opened. The opening of the valve r operates a switch t which energizes a sparking plug u. The pressure developed by the burning fuel acts on the piston g and causes it to discharge fuel to the inlet of the pump a at the same time closing valve e. It is stated that the supply of fuel from the chamber f and the accumulator reduces the size of the motor required to drive the pump a. A spring loaded valve admits air to the combustion chamber.

Abstract: 1403683 Powder dispensers for dish washing machines EUROPE Mfg TRUST 2 Feb 1973 [4 Feb 1972] 5405/74 Heading A4F [Also in Division D 1] A powder dispenser for a dish washing machine comprises, in a first embodiment, a powder compartment which is closed by manually pivoting a door 2 against the action of a spring until a slot in a cam 12 attached to the door spindle coacts with a projection on a locking means 17. The means 17 is maintained in the locking position shown by a spring-biased pivoted metal plate 20, until an electromagnet 19 is energized by the automatic program control of the machine which causes abutment of plate 20 and magnet core 22. Movement of means 17 is facilitated by the inclination of the abutting surfaces (32) (34) Fig. 3a, (not shown) of the cam and means 17. A second compartment is initially open, being closed by door 2 on opening of the first compartment. In a further embodiment, each of two compartments has separately operated doors. The configuration of the cam 12 and locking projection allows manual opening of a compartment after locking in the event of accidental locking.

When the cutting-off operation is completed, a further valve releases the pressure in the cylinder 24 and the head stock 12 is withdrawn. To ensure that the blades do not touch a switch or valve or a stop bar 34, adjustable for length by a screw 35, is provided in the path of both head stocks or additional trip switches or valves are provided. The upper gripping jaw 37 is movable by a fluidpressure cylinder 47 connected by a lever to one of several holes in the upper part of the jaw and the lower jaw 38 has arms 50 adjusted to the curvature of the stock by bars 51.. The stock may be advanced by hand or by an automatically-operated fluid-pressure cylinder.
