Title: Improvements in or relating to amusement apparatus or roundabouts
Inventor: MAXWELL GEORGE
IPC: A63G1/24
Filed: 1952-03-06
Abstract: 710,208. Roundabouts. PLEASURELAND, Ltd. May 6, 1953 [March 6, 1952], No. 5847/52. Class 132(1) Passenger cars are carried at the outer ends of arms 9 whose inner ends are independently hinged to a rotatable central support so that each car may be raised and lowered by a ram 13 in a cylinder 14, the supply of pressure fluid to the cylinder being controlled through a control device by the passengers in the car. An annular platform 5 is supported on rollers 6, running on a stationary structure, and supports structures 8 which carry arms 9 and ram cylinders 14. The control mechanism on each car, Fig. 2, comprises a valve casing 20 containing valves 21, 22 normally held closed by springs 23, so that rocking of lever 18, pivoted on casing 20, causes one of two heads 29 to engage one of two corresponding spindles 27, 28 to open either valve 21 or valve 22. Opening of valve 21. allows pressure fluid from pipe A to flow through pipes B<SP>1</SP>, B<SP>2</SP> to cylinder 14 to raise ram 13 and hence the arm 9, and opening of valve 22 allows the escape of fluid through pipes B<SP>1</SP> B<SP>2</SP> to an outlet port 31 so that the ram 13 and hence the arm 9 is lowered. A central distributing valve device comprises a cylinder 32 having an inlet 34 connected by pipe 35, via valve 36 controlled by an attendant, to supply pipe 39, Fig. 4. This cylinder is connected by hollow column 37, having inlet 38 from pipe 39, to valve casing 16 having outlets 42, 43. Pistons 44, 33 joined by rod 46 are slidable in casing 16 and cylinders 32 respectively. When valve 36 is opened to admit pressure fluid to the underside of piston 33, this piston and piston 44 are raised, thereby opening ports 42 to the inside of casing 37 to which pressure fluid is supplied through inlet 38. Ports 42 are connected by pipes A to inlets 23 on the control mechanisms on the cars. When the attendant operates valve 36 to cut off the pressure fluid supply and open pipe 35 to pipe 51 open to the atmosphere, pistons 33, 44 move downwards and pressure exerted through ports 43 from pipe B opens valve 48 so that pressure fluid in pipes B<SP>1</SP>, B<SP>2</SP>, B escapes. Thus when valve 36 is open and pressure fluid is being supplied to the control mechanisms on the cars the passengers may control the height of each car independently by means of one of the levers 18.

Abstract: 751,786. Discharge apparatus. PHILIPS ELECTRICAL INDUSTRIES, Ltd. March 3, 1954 [March 3, 1953], No. 6235/54. Class 39 (1). [Also in Group XL (b)] The Specification describes a construction of ionization chamber for use in X-ray timing apparatus. As shown (Fig. 1) X-rays from a source 1 passing through the body 2 under examination to a photographic plate 3 traverse the ionization chamber 6, which is a flat rectangular box having walls of insulating and X-ray absorbing material, e.g. " Perspex " (Registered Trade Mark). The internal surfaces are coated with a conductive material, for example graphite, but whereas layer 8 is continuous, layer 9 is divided into fields which are insulated from one another by scraping off the graphite along narrow parallel lines. Outside the chamber is a further electrode 10 which forms with each component of field 9 a condenser thus enabling the conductivity of the individual ionization chambers to be detected capacitively. The capacitors may be discharged by moving the walls of the chamber together until the coatings 8 and 9 engage each other. In a modification (Fig. 3, not shown), the external electrode is omitted, each component of field 9 being connected to an associated condenser by a wire passing through the insulating wall. As an alternative to graphite the layer 9 may be made up of a regular mosaic of groups of fields of different materials capable of different degrees of photo-electric emission by the action of X-rays, e.g. tin, copper and aluminium.
