Title: Improvements in or relating to internal combustion turbine engines
IPC: F02C5/06
Filed: 1963-12-11
Abstract: 1,009,962. Gas turbine engines. W. LOH BERG. Dec. 11, 1963 [Dec. 12, 1962], No. 48904/63. Heading F1G. The invention relates to an internal combustion turbine engine which comprises a rotary turbine member having one or more combustion spaces provided therein, the rotary member being co-axially mounted with respect to an axially movable piston rod of a compressor, and being co-axially surrounded by a fixed combustion chamber ring. The engine shown comprises a rotary member 1 which is supported for rotation by bearings 11 beteen fixed members 12, 12<SP>1</SP>, the rotary member being disposed within a fixed ring assembly 2, 2<SP>1</SP> in which is disposed a plurality of combustion chambers 21, 21<SP>1</SP>. The rotary member has a central bore in which is disposed an axially movable piston rod 4 which has secured at its left-hand end a compressor piston 5 which is disposed within a cylinder 6 having end plates 7, 8, an inlet valve 10 being mounted in the end plate 8. The piston rod 4 is formed with an axial groove 3 by which fuel and air mixture compressed by the compressor may pass to a distribution chamber 16 formed in the rotary member 1, the mixture then passing through ducts 15, 15<SP>1</SP> to combustion spaces 14, 14<SP>1</SP> formed in the rotary member, the spaces 14, 14<SP>1</SP> communicating by way of ducts 20, 20<SP>1</SP> with the periphery of the rotary member, the arrangement being such that as the member rotates the ducts communicate successively with the combustion chambers 21, 21<SP>1</SP>. Spark plug devices 23, 23<SP>1</SP> are disposed in the chambers 21, 21<SP>1</SP> as shown so that in the position shown the mixture is fired and the resulting expansion causes the member to rotate. The gases act successively in the chambers 21, 21<SP>1</SP> and finally discharge through outlets 19, 19<SP>1</SP>. The rotary member is connected to drive the piston by means of gearing and a connecting rod 13. The compressor piston is arranged so that as it moves and compresses the mixture in the space to the left of the piston, it reaches a position whereby it uncovers a port and so causes the compressed mixture to be transferred through a duct to the space to the right of the piston thence passing through the duct 3 and so to the distribution chamber 16 in the rotary member. Passages 18, 18<SP>1</SP> are formed in the rotary member for flow of cooling fluid.

As shown, the probes are mounted in a peripheral recess 51 of the reference electrode which comprises a coating 23 of conductive material deposited on an insulating substrate 24. A reference electrode in the form of a truncated conical configuration is also described (Figs. 5, 6).

Abstract: 1,145,170. Variable capacitors. OXLEY DEVELOPMENTS CO. Ltd. 6 Oct., 1967 [5 Nov., 1966], No. 49684/66. Heading H1M. In a variable capacitor axial movement of the piston-type movable electrode 18 is by rotation of a screw, the shank portion 32 of which engages threaded opening 24 in the end wall 22 of the piston, the head 30 of the screw being mounted in cap 12 closing one end of dielectric sleeve 10, and being prevented from inward axial movement by lip 34. The arrangement is such that the screw does not penetrate into the electric field of the fixed electrode 36 and a high Q-factor is obtained in the position of minimum capacitance. Rotational movement of the piston is prevented, e.g. by its having a longitudinal flat surface abutting a corresponding flat surface in sleeve 10 (Fig. 2, not shown), and anti-backlash springs 38 are provided.

[Class 135] A direction-stabilizing device for use on ships, aircraft, or other vehicles for adjustment of the steering mechanism or for keeping instruments or other apparatus such as cameras adjusted in a predetermined direction of the kind having a servomotor controlled by a control device having one part operated by a pendulum or gyroscope co-operating with another part actuated by the power device has the two parts of the said control device adapted to assume two or more different neutral positions in relation to each other and in each one of these positions, to transmit the impulses of the sensitive member to the power device in the sense required to correct any deviation. In the form shown in the Figures, the power device comprises a pair of opposed vanes and working in semi-cylindrical chambers and mounted on a hub connected on the one hand by a shaft 15 with a pulley 17 coupled to the part to be operated, and on the other hand by a shaft 16 to the moving seat part 18 of a rotary disc valve assembly.- The control valve member 19 has an internal chamber 24 supplied with compressed air through the hollow gimbal ring 3 of a gyroscope 1 to which ring the valve member is secured. The face of the valve seat has four arcuate recesses coupled together in pairs, each pair in turn being connected by passages in the shaft 16 with diametrically opposed chambers in the motor. The valve member has two supply ports 26, 26<1> leading from the internal chamber 24 and normally obturated by the parts of the valve seat lying between the recesses 28, 29 and 28<1> 29<1> respectively. Similarly a pair of exhaust ports 27, 27<1> leading to the edge of the valve member are normally obturated by the parts of the valve seat lying between the 28, 29<1> and 28<1> 29 respectively. A clockwise movement of the valve member will admit pressure to two chambers of the power device and connect the other two to atmosphere, while an anticlockwise movement will reverse these' connections. On turning the valve member through 180‹, clockwise and anticlockwise movements will energize the same chambers as before. The control mechanism can have more than two neutral positions and a turbine or reciprocating piston motor may replace the oscillating vane motor. Specification 500,840 is referrcd to.

Abstract: 1,150,705. Contacting liquids with gases. IMPERIAL CHEMICAL INDUSTRIES Ltd. 6 Nov., 1967 [14 Nov., 1966], No. 50914/66. Heading B1R. Batches of liquid to be contacted with a gas are supported in a series of superposed chambers by plates 2 with perforations 4, the arrangement being such that the normal pressure of the gas passing upwardly through the perforations 4 and the liquid thereabove prevents passage of liquid through the perforations but allows intermittent advancement of each batch of liquid from chamber to chamber to a liquid discharge outlet 12, the passage of gas through the chambers being maintained throughout. As shown the free space above each patch of liquid has a branch conduit 6 connecting with a common conduit 5 and a gas outlet 7, valves 8 being provided in conduit 5 between each pair of conduits 6. In normal operation all valves 8 are closed and gas entering at 11 bubbles upwardly through each batch of liquid. When it is desired to advance each batch the lowermost chamber is emptied by opening valve 13 in outlet 12. The lowermost valve 8 is then opened so that liquid -from the superjacent chamber can pass by gravity into the thus emptied lowermost chamber. This transfer of liquid is repeated in successive chambers above until each batch of liquid has been advanced.
