Title: Rotating and reciprocating piston machine or engine
Inventor: WYRSCH ISO
IPC: F02B33/34
Filed: 1989-12-19
Abstract: The rotating and alternating piston machine is an alternating or free piston machine in which the pistons effect a rotating and alternating movement. Main characteristics: 1) the use of rotation or alternation/rotation, for example in order to control the ports provided in the cylinder walls of two- and four-stroke engines, pumps and compressors; 2) simple conversion of rotating and alternating movement by mechanical or electrical means. The rotating and alternating piston machine offers the possibility of: pumps, including the electric drive, in which there is only one rotating part; direct conversion of the alternating movement of the piston into electrical energy; control of the gas movement by the piston; operation of other ports having specific functions (for example, introducing additional compressed gas, discharge ports operating in succession etc.); free selection of the number of piston strokes per rotation; choice of piston stroke kinematics; powerful rotation or swirling of charge; easily designed compact and inexpensive machines; possible integration of a compressor without having to provide for an additional volume and virtually without any weight increase. In the two-stroke combustion engine, in which the gas exchange is controlled by the pistons (2 and 5), the useful power is available at the central shaft (14), which carries the rotating and alternating piston (2) in a longitudinally-slidable but rotationally-fixed manner. Movement is converted by the oscillating shaft (35) and transmission element (38). The engine is provided with four working chambers and has a 100% mass balance.

Title: Control system for synchronous motor
Inventor: SADLER GORDON
IPC: H02P25/02
Filed: 1990-10-31
Abstract: A control system for driving a low torque synchronous motor is described which drives the motor to have a smooth rotation. The windings of the motor are energised whereby to provide a motive magnetic field which is dependent on the angular position of the rotor. The variation with angular position is inverse to the variation with angular position of a further torque caused by other features of the motor, e.g. physical features. The variation in the torque generated by the windings therefore compensates for the variation in the further torque. A preferred application of this invention is to analog displays, for instance car instrumentation.

Title: Side-entry sheaths for needles or sharp instruments
Inventor: LISTER ARTHUR HUGH
IPC: A61M5/32
Filed: 1992-08-24
Abstract: It is important to protect personnel from injury by needles contaminated with blood. Two designs of sheath are presented which afford protection to the fingers whilst re-sheathing a needle in the usual way (Figs 1 & 2). Two designs are presented of a sheath that pivots laterally so that the sheath does not interfere with the use of the needle but may be flicked back over the needle safely and easily (Figs 3 & 4). A design of sheath is offered which whilst being less secure is designed to hug the body of a narrow syringe when the needle is exposed. This design may have application in dentistry where space is limited (Fig 5). A design is offered for the "butterfly" (Fig 6). Finally 3 designs are offered the first of which is a simple plastic moulding. It clicks onto a modified noodle hub in such a way that it is normally held guarding the needle but may be pivoted out of the way and flicked back over the needle after use (Fig 7). The last two designs are modifications which offer more security at the expense of being more complex (Figs 8 & 9). <IMAGE>
