Patent GB-2132042-A (GB)
Title: Frequency and timing sources
Inventor: CHAMBERS JOHN PHILIP
IPC: H03L7/099
Filed: 1983-12-15
Abstract: A frequency or timing source comprises a stable oscillator 31, a programmable divider 32, and a comparator 36 which receives the divider output and also an intermittent external reference. In the presence of the external reference an error determination is made and applied to a controller 34 which includes a memory section. From the error the controller determines the amount by which the divider must change its division ratio to remain in synchronism with the reference in the future. Thus the system learns how to improve its operation. If the response of the oscillator to temperature changes is known, a measure of temperature can also be applied to the controller 34 for appropriate compensation in the divider 32; alternatively this compensation can be learnt by correlating the temperature with the correction applied. An improved binary rate multiplier is also disclosed (Figures 4-7). <IMAGE>

Title: A visual training aid for athletes
Inventor: JONASAR AEVAR
IPC: A63B69/00
Filed: 1985-12-17
Abstract: A visual training aid for athletes such as swimmers comprised of a circle of spaced lights which can be selectively actuated such that a point of light moves clockwise around the circle at a particular speed to enable an athlete to pace his performance during a training sequence. In one mode of operation the lights are extinguished one by one at a predetermined speed until all the lights in the circle have been extinguished whereupon the circle is re-illuminated and the cycle can continue as desired, each cycle being incremented on a display counter to indicate distance travelled by the athlete. In the second mode of operation at the start of a training sequence, all the lights in the ring are illuminated with the exception of a group of five consecutive lights which provide "a black hole" in the circle. At the start of a training sequence the "black hole" is moved clockwise around the circle, the leading edge of the black hole providing the observable movement required. The aid provides inter alia excellent psychological effects in terms of improving an athletes performance, and obviates the attention of a trainer, or the use of a pace swimmer or runner as the case may be. <IMAGE>

Title: Resilient support cushion
Inventor: PAXON JOHN BERNARD
IPC: A47C7/42
Filed: 1987-01-29
Abstract: A convex resilient support pad (2) resting on a plate or board or on strips placed across a frame (1). The complete structure or assembly can be placed between two pieces of foam for example (10) and finally covered by an outer case (11) to form a cushion. The resilience of the mass or convex support pad makes the whole cushion automatically adjustable to suit the weight of the user. The plate or board may be in the form of a wide frame into which a mass, that is fitted to resilient strip fixed by a sliding fit into guides fitted to the surface of the frame, can move inwards against the weight of the user. On a solid board without a hole the mass may itself be resilient or can be resting on resilient bases held onto the board by the foam on or surrounding them or by other means. The board or plate may be longer than the cushion to form a rest for the head or a support for the head-rest. An additional extension (14) board can be fitted to support the head of the user or a head-rest (12) that may be adjustable and that may be trapped in the desired position by an additional cover (15). The Resilient Support Cushion can be made with a folding area (17) that helps to prevent creasing when packed.
Patent GB-2187553-A (GB)
Title: Seismic wave generator with shock absorber
Inventor: AIRHART TOM P
IPC: G01V1/147
Filed: 1987-02-20
Abstract: An impact type surface seismic source propels a heavy mass 24 from a raised position downwardly to strike an earth contacting base plate 12 which couples the resultant energy into the earth as a seismic wave. Hydraulic cylinders 52 have piston rods 50 which are linked with the mass via a flange 46 and engage it in its downward position, lifting it rapidly from the base plate to its original raised position. Cushioning means (hydraulic means and/or spring assemblies) are engineered in to the lift system in order to control the rate of increase of upward force exerted upon the mass as lift is applied. This significantly reduces the secondary seismic shock wave which would otherwise result from the rapid removal of the weight of the mass from the base plate. <IMAGE>

Title: Pool table lifting device
Inventor: DAVIES BARRY CHRISTOPHER
IPC: B66F7/06
Filed: 1987-07-09
Abstract: The pool table lifting device is a base A mounted upon four swivel wheels upon which is welded two scissor jacks B with cross members affixed to the top of each jack C. When the lifting device is wheeled beneath the underside of a billiard or pool table, the screw jacks are operated by means of an extended key (D, fig 2), allowing the cross members to rise in height and to contact, and lift, the underside, and consequently the fixed legs of the billiard or pool table. The lifting action is then continued until the fixed legs of the table are judged to be clear of the floor or floor covering. The billiard or pool table may then be pushed to another location using physical effort by running upon the four swivel wheel fixed to the base of the device. When the desired location is achieved, the screw jacks are lowered, thus permitting the billiard or pool table to stand again in its new position on it's own fixed legs. The device may then be stored until a further application. <IMAGE>
