Patent GB-2103943-A (GB)
Title: Electronic game board
Inventor: BLENKINSOP PHILIP THOMAS
IPC: A63F3/02
Filed: 1982-07-19
Abstract: The board, e.g. a chess board, senses the position of and nature of each playing piece 20. Each playing piece has an electrical resonant circuit 30 tuned to a particular frequency to distinguish it from the other pieces, and each board play position has a transmitter 22, which emits a pulse of electromagnetic radiation to induce resonance in the resonant circuit of a piece positioned on that board position, and a receiver 24. A discriminator determines the resonant frequency received by each receiver and thereby determines the nature of the particular piece or absence of a piece on that position. The discriminator determines the time span of a set number of received oscillations, e.g. by gating the count from a regular oscillator and the board stores the positions of the pieces. <IMAGE>

Title: Method for tracking signals on disc records
Inventor: GOTO KUNIO
IPC: G11B7/09
Filed: 1982-10-27
Abstract: Information recorded on a disc record track (11) laterally undulates at a frequency having a predetermined relationship with the speed of revolution of the disc preferably an integral multiple K of the speed of disc rotation where K is an even number of half an odd number. A pilot signal of frequency of the track undulation is modulated on a carrier so that the pilot signal phase on each track is aligned in radial directions the signal may be horizontal sync. signals of a composite signal TV or frame sync. bits. On playback, a first tracking signal is derived by a band-pass filter from the geometric variations of the undulating track and a second tracking signal is derived by a demodulator from the recorded pilot signal (Figures 7, 12 (not shown). A synchronous detector is provided to multiply the first and second tracking signals to generate a control signal for counteracting a lateral displacement from the right track. The capacitative disc may have spiral or concrete tracks. Recording may be via a cutting disc (Figure 2, not shown) or optically (Figure 6, not shown). The intertrack grooves may be omitted (Figure 5, not shown). In Figure 8 (not shown) the undulation of each track is 180 DEG out of phase with adjacent tracks, fabrication being as in Figure 9 and 14 (not shown), the polarity of the pilot signal being reversed for alternate cycles of revolution and a burst index signal provided at the start of each revolution, and tracking control as in Figure 12 (not shown). <IMAGE>

Patent GB-2113207-A (GB)
Title: Preparation of alkylene carbonates
Inventor: HARVEY ROBERT J
IPC: C07D317/36
Filed: 1982-12-02
Abstract: Alkylene carbonates, particularly ethylene carbonate, are prepared by the reaction of an alkylene oxide with carbon dioxide in the presence of a catalyst at temperatures ranging upwards from 20 DEG C, particularly temperatures above about 90 DEG C, preferably 90-170 DEG C. The conversion of alkylene oxide to alkylene carbonate can be carried out in the presence of water while minimizing the undesirable hydrolysis of the carbonate to the corresponding alkylene glycol and formation of higher glycols. This is achieved by maintaining the water to alkylene oxide molar ratio and the carbon dioxide to alkylene oxide ratio within stated limits and adjusting the carbon dioxide partial pressure to provide the desired selectivity to alkylene carbonate.

Patent GB-2147368-A (GB)
Title: Hydraulic apparatus
Inventor: JONES PHILLIP
IPC: F01B11/00
Filed: 1983-09-28
Abstract: An hydraulic ram (10) includes at least one end of its cylinder one or more control valves (14a, 15a) which are engaged by the piston (11) at the end of its stroke and arranged to control the supply of hydraulic fluid to the cylinder. In a preferred embodiment of the invention as applied to a double- acting hydraulic ram, control valves (14a, 15a; 14b, 15b) are provided at opposite ends of the cylinder and control the operation of a main changeover valve (16) through an intermediate changeover valve (22). As shown, piston (11) is at the left-hand limit of its travel, depressing valves (14a and 15a) so allowing fluid to flow from source (P) through lines (20 29a and 27) to drive changeover valve (22) to the right. This connects line (25) to the supply (P) and drives the spool of valve (16) also to the right. Consequently compartment A is pressurised through lines (17, 13a) and piston (11) moves to the right, releasing valves (14a, 15a) and eventually depressing valves (14b, 15b), reversing the process. This may be part of a hydraulic intensifier. <IMAGE>

Title: Disc transport apparatus
Inventor: UEHARA TSUKASA
IPC: G11B17/04
Filed: 1984-03-26
Abstract: Disc apparatus for use with a flexible magnetic disc 1 in a cassette 2, the disc having a core 3, comprises a motor 7 driving a spindle 8 with a core receiving flange 8a, and a cassette holder 21 movable in direction A to engage disc core 3 with spindle 8. Free end 23a of pivoted pressing arm 23 exerts a force on core 3 fully to engage the core 3 with the spindle 8 as the holder moves in direction A. As the holder (eg operatively connected to cover or chassis) reaches a second position where the disc is fully engaged, pressing arm 23 automatically withdraws from the disc 1, to leave the disc free for rotation by spindle 8. On raising the holder 21 in direction B to lift the disc off the spindle, the pressing arm remains in its raised position, clear of the disc core. The pressing arm may be disabled before or after holder 21 reaches the second position. Arm portion 23c is flexible to accommodate tolerance variations etc, or in (Fig. 9) arm (23) may move along slot (23g), while in (Figs. 12 to 14) a toggle or snap spring mechanism (74) is responsive to excessive force. Other embodiments are detailed (Fig. 6) et seq.. Hole 3a diameter is relatively small so tolerance variations less affect positioning.

Patent GB-2137282-A (GB)
Title: Pressure regulating devices
Inventor: CANE MICHAEL ROGER
IPC: E21B17/02
Filed: 1984-03-29
Abstract: A fluidtight body disposed in ambient medium which varies in pressure and temperature, e.g. a fluid-filled body 17 surrounding an electric connector 11, 12 disposed "downhole" in an oil well, has its internal pressure regulated in order to minimise the pressure difference between the inside and the outside thereof. To this end a shallow recess 24 in the outer surface of the body is enclosed by a flexible diaphragm 26 having its exterior exposed to the high ambient pressure. A narrow passage 25, preferably of capillary dimensions, connects the recess 24 to free spaces within the body 17 which are filled with an electrically insulating fluid e.g. silicone grease and a certain amount of air. The diaphragm is flexible enough to be deformed without injury so as to enter the recess and reduce its volume substantially and preferably practically to zero. The recess 24 contains a volume of air which for optimum performance should be equal to the amount by which the volume can be reduced by movement of the diaphragm and also equal to the volume expansion of the fluid from atmospheric conditions to mean working temperature. By this means, the diaphragm is substantially unstressed both under atmospheric conditions and under mean working conditions, since the air will be compressed to a negligible volume. <IMAGE>

Patent GB-2144040-A (GB)
Title: Measuring aerobic capacity
Inventor: SYKES KEVIN
IPC: G04G21/02
Filed: 1984-06-14
Abstract: Means for determining aerobic capacity comprise first means for defining a sub-maximal exertion test, such as instructions (20) for determining the test, e.g. as a step-test, and apparatus (24) for use in carrying out the test; second means for controlling the test which may comprise a timer to indicate times at which to make a pre-determined number of exertions; third means for determining pulse count e.g. timing means (30) set to time a pre-set interval within which to count the pulse; and fourth means related to the test for conversion from a combination of the parameters sex, age and the pulse count to aerobic capacity. Audible timing signals, preferably pre-recorded on a recording medium may be used to indicate various intervals. The correlation (42) of aerobic capacity to the said parameters may be presented in a table or on a circular slide scale. Alternatively, a data processor can be provided with having data input means for the parameters and data output for aerobic capacity, and programmed with a stored set of values of an aerobic capacity corresponding to each combination of sex, age and pulse count. A computer may be programmed to display instructions defining said test, for producing timed signals to indicate when to make exertions of the test, for timing the start and end of the pulse count in a pre-determined relation to the test and to give an aerobic capacity value for a given combination of input sex, age and pulse count data.

Title: Vacuum cleaner for wet waste
Inventor: TAYLOR LEONARD
IPC: A47L5/36
Filed: 1984-06-14
Abstract: For use in picking up liquids or wet waste a vacuum cleaner having an upright drum 2 for receiving waste material, an outlet through a filter 15 for air from the upper part of the drum and an inlet 8 for waste material to enter the upper part of the drum, is provided with a baffle 71 fitted in the drum. The baffle 71 separates the part of the drum having the inlet 8 from that having the air outlet. This causes air to follow an extended route within the drum from inlet to outlet and encourages the deposition in the drum of liquid entrained in the air and helps to avoid the picking up by the air flow of liquid from the drum. A first element 72 divides the upper part of the drum into vertically spaced zones in communication only through a central aperture 76 in the element 72. A second element 73 of U-shape extends towards the bottom of the drum and shields the aperture 76 from the inlet 8. A float-operated valve 82 may be provided to close the aperture 76 when the liquid level reaches a predetermined level. <IMAGE>
