Title: Replenishing the helium bath in the rotor of a superconducting generator
IPC: F17C6/00
Filed: 1980-05-29
Abstract: In order to replenish a helium bath 5 in the superconducting rotor 9 of an electrical machine, in which bath liquid helium boils at subatmospheric pressure, with liquid helium from a helium reservoir (not shown), the liquid helium in the reservoir being at ambient pressure and a part of the liquid helium changing to the vapor phase during flow from the reservoir to the bath, liquid helium is introduced via conduits 4, 12 into the bath 5 at a distance (R2) from the rotor axis of rotation 8, the liquid and vapor phases of the helium flowing from the reservoir to the bath are separated from one another in a phase separator 2 fixed to the rotor, and the separated vapor phase is extracted from the separator, being led away along coaxial conduit 6. The radius R0 of the liquid/vapour interface in the separator 2 is automatically controlled using a sensor 7. <IMAGE>

Title: Improvements in bending brakes
IPC: B29C53/04
Filed: 1981-03-17
Abstract: In a sheet bending apparatus, in which a workpiece (X) to be bent by means of a bending bar (32) is clamped between an anvil plate (38) and a clamping member (54), the clamping member is spring loaded by oval spring members (70) which are arranged between pivot bars (62), to which the clamping member is attached, and a handle member (66) pivoted to the upper arms (26) of C- frames (14). The spring force can be adjusted by means of a screw (82) and a wedge (80). This adjustment enables workpieces (X) of different thicknesses to be clamped and the resilience of the spring members (70) compensates for tolerance variations in the workpiece thickness. <IMAGE>

Title: Ratio encoder for slot machine reels
IPC: G07F17/34
Filed: 1981-09-23
Abstract: A ratio encoder encodes the instantaneous angular position of one or more spinning reels in a microprocessor controlled amusement game such as a fruit machine. The ratio encoder provides substantially instantaneous angular position data to the microprocessor by measuring the ratio of two voltages generated by electrical resistance track 11 on the reel's periphery. One of the voltages may be a reference voltage applied to the ends of resistance track 11 via slip rings 14, 16 and the other may be substantially proportional to the angular displacement of the reel from a reference position as detected by slider 18. The ratio, which is thereby rendered independent of supply current fluctuations, may be obtained as an analogue voltage from meter 22, converted to digital form at 23 and then supplied to the microprocessor. <IMAGE>

Title: Apparatus for controlling the position or movement of a member
Inventor: STEPHENS PHILIP EDWARD
IPC: H04B10/80
Filed: 1982-12-20
Abstract: Conventionally, such things as flaps on aircraft are controlled by sending electrical signals from a control consol operatored by a pilot to servo-mechanisms distributed about the aircraft. Such signals are subject to interference from electrical, magnetic or electro-magnetic disturbances arising outside the aircraft which in extreme cases may result in the pilot losing control of the aircraft.   In an attempt to reduce such interference hydraulic valves (such as that shown at 13), which are distributed throughout the aircraft and which control the movement of members such as flap 1, are powered by electromagnetic radiation transmitted along lines 9 and 9' and produced by lasers 7 and 7', which are supplied by a common power source 8. <IMAGE>

Title: Systems for the issue of tickets
Inventor: ADAMS LESLIE
IPC: G07F17/42
Filed: 1983-07-15
Abstract: Ticket stock from one of two reels (9, 10) is fed through a guillotine cutter (11) such that a freshly cut blank ticket (20) is permitted to lie in a rest position (6) between two pairs of rollers (21, 24, 22, 24). An enabling signal generated by a coin sensing mechanism (3) causes the blank ticket (20) to be conveyed on a path over a recording head (13) and under a printing head (14) to an exit slot (15), to be printed and encoded at the time of issue. A new blank ticket length is automatically cut and fed into the rest position as the previous ticket exits, thereby permitting a response time to ticket issue having no component due to the cutting time of ticket stock. <IMAGE>

IPC: B27N3/14
Filed: 1983-08-11
Abstract: A method of spreading ligno-cellulose and binding agent containing material consisting of fine and coarse particles in the manufacture of cement-bound particle boards uses apparatus comprising a metering belt (1) supplying the material to a spreading roller (2) from which the particles are entrained and directed to a forming belt (6) disposed beneath the metering belt (1) by an airstream (14) generated by an air guide roller (3) situated between the belts (1, 6). The belts (1, 6) and air guide roller (3) are located in a spreading chamber (K) which is substantially closed by a baffle wall (4) and an air guide wall (5). The fine particles are entrained directly by the airstream (14) onto the forming belt (6) whilst the coarse particles fly farther and are deflected by baffle wall (4) onto the forming belt (6) to give better distribution of the coarse and fine particles in the preform (10). <IMAGE>

IPC: B41J1/24
Filed: 1983-08-15
Abstract: A printing apparatus comprises an input device for entering a plurality of sets of data, each set including title information and character information associated with the title information. A memory stores a plurality of the sets of data entered by the input device and a printer is responsive to sets of data read from the memory to print any one of those sets of data either fully or partially. A selection device selectively causes the printer to print any one of the sets of data either fully or partially. The printing apparatus may also include a selector for selecting one of a first printing mode and a second printing mode. In the first printing mode, when selected, the printer is caused to print both the title information and the character information which may comprise text information. In the second mode, the text information is printed without the title information.
