Patent GB-2259332-A (GB)
Title: Hermetic compressor with rotary rolling piston
Inventor: DA COSTA CAIO MARIO FRANCO NET
IPC: F04C18/356
Filed: 1991-09-06
Abstract: The invention relates to a hermetic compressor with a rolling piston 50' of annular section, enclosing a crankshaft 60' having an eccentric portion 60a'. The piston 50' rolls around the eccentric portion 60a' of the crankshaft 60', all held within a cylindrical chamber of a cylinder block. The piston 50' acts in combination with a sliding vane to separate the cylindrical chamber into suction and discharge regions. These regions have lower internal pressures than the oil elsewhere inside the shell of the compressor, during most of the cycle of rotation of the piston 50'. Consequently, oil passes through small gaps between the annular end-faces of the piston 50' and the end walls of the cylindrical chamber, to lubricate, and seal, components of the compressor. By providing a rolling piston with a high ratio of external to internal diameter (greater than 1.63 but preferably less than 2.22), the radial path of the lubricating oil is increased. In this way the flow of lubricating oil is reduced, without the disadvantage of the conventional method of reducing oil flow, in which the annular faces are moved closer to the end walls of the chamber resulting in increased friction. Furthermore, the crankshaft has an end portion 60b' which has a radius R which satisfies the condition    2Rr > Rm + Ec + Re where  Rr is the internal radius of the piston 50', Ec is the eccentricity of the eccentric portion @60a' of the crankshaft 60' and  Re is the radius of the eccentric portion.   <IMAGE>

Title: Siphon tube
Inventor: WICKS STEPHEN ERIC
IPC: F04F10/00
Filed: 1991-11-07
Abstract: A syphon comprising a tube 16 having at its inlet end a valve 10 comprising an elongate enclosure 11 communicating at its outlet end with the tube and open to the exterior at its inlet end through an inlet passage 17 closable by a spool member 12 reciprocable longitudinally within the enclosure 11, the enclosure 11 being such as to guide the spool member 12 during one stroke of its reciprocation to a position at which it temporarily closes the inlet passage 17 to prevent the flow of liquid out of the valve, and such that at all other positions of the spool member 12 the enclosure allows the flow of liquid from the inlet passage 17 around the spool member and through the outlet end of the valve 10 into the tube 16. The syphon tube is intended to handle toxic or corrosive liquids, and is made of plastics material, the spool 12 being of glass and urged towards the inlet passage 17 by a compression spring 25.

Patent GB-2252839-A (GB)
Title: Recording medium
Inventor: BARKER DAVID JOHN
IPC: B41M5/00
Filed: 1991-12-04
Abstract: A thermo- or pressure-sensitive recording medium comprises a microporous thermoplastics film having a fibrillar or reticulated structure, preferably produced by stretching the film which contains particles of a filler and optionally removing the filler, and a coloured underlayer. Impact on the microporous film causes it to change from an opaque to a clear state revealing the coloured underlayer. The medium may be used to reveal impact e.g. of a golf ball on the head of a golf club to which it is attached, it may be printed in an impact or thermal printer or it may be used to detect temperature rises above a characteristic limit at which the film becomes transparent.

The ring element 43 may have expanded flank portions in the middle to form a middle section of appropriate width so as to form a larger space to form larger bubbles (Figure 6). <IMAGE>
Patent GB-2265673-A (GB)
Title: Pump
Inventor: WRIGHT LUKE FRANK
IPC: F04B33/00
Filed: 1992-03-26
Abstract: A pump comprising a cylinder 2 having a first end 3 and a second end 4, a piston in the form of a washer 8 which reciprocates within the cylinder and compresses air between itself and the first end 3 has an aperture 10 in the wall of the cylinder 2 towards the second end 4. As washer 8 moves towards end 4, a pressure differential is built up between chamber "A" and "B" as pressure in chamber "B" increases and pressure in chamber "A" tends towards a vacuum. Washer 8 contracts and allows air to pass between its circumference and the cylinder and some air to pass from chamber "B" to "A". However, excess pressure "B" is allowed to vent through aperture 10 making movement towards end 4 easier. When washer 8 travels past aperture 10 into the position shown in dotted lines 8a, chamber "A" is immediately filled to atmospheric pressure. Use of the aperture 10 thus allows the washer 8 to move more freely in the cylinder 2 making the pump easier to work and more efficient. <IMAGE>

Title: Automatic adjustment of bandsaw blade guides and determination of workpiece shape and dimensions.
Inventor: MORIYA KIKUO
IPC: G01B7/04
Filed: 1992-06-23
Abstract: A bandsaw machine has at least one movable saw blade guide 29 the position of which is varied automatically in accordance with changes in the shape of the workpiece W being cut. The blade guide position may be controlled by workpiece proximity detectors, or by means for rotating the saw blade position to the shape and dimensions of the workpiece which may be determined by automatic means. Such means may comprise a contact angle detector 31, a width detector 33 and a vertical surface detector 35. The angle of contact of the saw 23 with the workpiece, the width D of the workpiece and the presence or absence of a vertical side are fed into a calculation device 39 which compares these values with those obtained from a series of equations relating to theoretical dimensions of different workpieces and selects the best fit to obtain an estimate of the shape of the workpiece W. Alternatively the dimensions of the workpiece W may be directly measured by a photographic device and image processing device. <IMAGE>

Filed: 1992-08-05
Abstract: Method of and apparatus for controlling drive between a gramophone disc and a drive turntable (6), comprises means (7) interposable between the gramophone disc and turntable (6) for transmitting rotational drive between the turntable (6) and the gramophone disc, said transmission element (7) having a first operational state which allows rotation of the turntable (6) without rotation of the gramophone disc and a second operational state in which the gramophone disc is caused to rotate with the turntable (6), the arrangement being such that the rotational drive to the gramophone disc is independent of the control of the drive system for the turntable. The drive transmission element (7) is magnetisable, the arrangement being such that a predetermined change in the magnetisation thereof is arranged to determine changeover from one operational state to the other of said operational states, for example by bringing electromagnet 9 into contact therewith by means of solenoid plunger (11-13) with simultaneous energisation of eiectromagnet 9, causing element 7 to be braked and thus slip with respect to turntable 6, holding the gramophone disc stationary until the braking is interrupted. <IMAGE>

Title: Radar jammer
Inventor: BEHARRELL G P
IPC: G01S7/38
Filed: 1994-02-07
Abstract: A jammer has a 3-level arrangement of control and generating radar-band ECM waveforms. An ECM Emission Generator provides a discrete pulse of RF power in response to a control signal from an ECM Emission Sequencer. The sequencer, responsive to a single received radar pulse or other event, produces control signals to the generator to produce ECM Emissions in a defined time relationship. Finally there is a high level ECM Mode Controller having a number of selectable modes, wherein each mode generates a series of sequence control signals for connection to the sequencer with each sequence control signal corresponding to a different emission sequence. The controller is arranged such that one or more of the emission sequences can be modified or replaced in response to a change of parameters of the target radar, preferably in a time interval approximating to the radar scan period, to present a situation to the radar that changes with time.
