Title: Competitive game
Inventor: TAYLOR PATRICK CHRISTOPHER MIC
IPC: A63F9/20
Filed: 1988-05-18
Abstract: The game utilizes a plurality of polygonal playing pieces e.g. in the form of blocks or cards or three dimensional and rules governing the placing of the pieces in a side by side relationship or in a one on top of the other relationship. The playing of pieces may represent the establishment of relationships between players or may represent players gambling on the fortunes of players who have already played pieces to represent relationships. The pieces are designed so that markings on the underneath surface thereof are invisible to players of the game when the pieces have been placed on a playing surface. The rules provide for scores to be allocated to players, dependent on the placing of pieces and the subsequent revealing of the markings on the underneath of some or all of the pieces - the markings or absence of markings underneath are termed 'positive', 'negative' or neutral edges. The game may involve deals between players but a player may decide secretly not to cooperate in a deal. Pieces may be triangular, square, hexagonal, pyramids, cubes and game may involve different forms - playing pieces of different players may be indentified by colour and/or shape. <IMAGE>

Title: Trackerball arrangement
Inventor: VEEL CHRISTOPHER JAMES
IPC: G06F3/0354
Filed: 1988-07-06
Abstract: A trackerball arrangement consists of a solid rotatable ball mounted within a housing and supported by a pair of rollers which run in bearings. Rotation of the ball by hand causes corresponding rotation of optical encoders attached to the rollers so that electrical signals are generated representative of the x and y rotation of the ball. As it is important for the bearings to operate freely with low friction, a tubular shield 10 is placed around the ball so as to prevent any liquid which splashes onto the top of the ball reaching the bearings. The rollers contact the ball via apertures in the shield. An upper plate 2 is provided with a lip 14 on its underside, which follows the curvature of the ball and prevents liquid from travelling onto the undersurface of the top plate 2. <IMAGE>

Title: Compact disc insertion and election system
Inventor: LIM KIM YONG
IPC: G11B17/04
Filed: 1989-11-14
Abstract: A compact disc player disc insertion and ejection mechanism comprises a tray (16) which is moved vertically whilst being driven into the housing. In operation the carriage (12) moves the tray (16) into the housing. Tray (16) carries a tray riser (40) which has an angled sawtooth surface (42), which initially rests atop tray riser pinion (44) whose rotational axis is fastened to the carriage. The tray riser pinion passes over a short rack (46) fixed to the front of the housing or chassis, and rotates relative to the fixed gear-toothed tray riser, causing the tray to rise above the carriage. The carriage passes over the motors of the housing and around the spindle motor on whose spindle (10) the disc will rest and rotate. When the disc is centered over the spindle, the disc supporting tray (16) ceases to move further into the housing with movement of the carriage. The tray riser pinion then rotates in the opposite direction thereby lowering the tray onto the spindle with the disc now resting on the spindle. <IMAGE>

Patent GB-2260193-A (GB)
Title: Shaped memory devices
Inventor: POWELL SIMON COLIN
IPC: H01H61/01
Filed: 1991-10-04
Abstract: Devices using memory metals are in general switch-like devices wherein the shape change as a memory metal element is caused to pass through its transition temperature and so changes its shape is employed to drive or trigger some action. The majority of these devices seem to have in common the feature that they are caused to operate directly by the temperature of the environment into which they are placed, but more recently there has been proposed a type of device wherein the element is controlled indirectly, by some parameter other than that which the device itself seeks to control. In this type of arrangement there is employed a self-contained memory metal device that is in effect separated from the ambient temperature conditions, being housed within its own ''micro-environment'', and being provided with heating means the action of which is at least primarily unrelated to the ambient temperature. Unfortunately, even these indirect devices have serious drawbacks, relating to the heat capacity of the memory element, which creates a considerable delay both before the element is activated and before, on cooling, it re-sets. The present invention proposes a possible solution to this difficulty by deploying the shape memory element (13) within a micro-environment (12) and then effecting its operation through the controlled application of both heating and cooling regimes, such that the working of the device (1) is quite independent of ambient conditions on both the strong and weak cycles, so enabling larger and hence more powerful elements to operate with rapidity.
