Title: Energy regulating switch
Inventor: SHEPHERD GEORGE RONALD
IPC: H01H37/14
Filed: 1983-01-31
Abstract: An energy regulating switch has a pair of contacts (2, 3) in series with a load (1). A bi-metallic strip (4) is operably associated with the contact 3. A cam (8) and a cam follower (7) are arranged to position the contact 2. First and second electrical heaters (5, 6) are arranged to heat the bi-metallic strip (4) with the first heater (5) connected in series with the contacts (2, 3) and in parallel with the load (1). A cam (11), a cam follower (12) and contacts (13, 14) are provided for connecting the second heater (6) in parallel with the first heater (5). A spindle (9) carries the cams (8, 11) and when rotated in a first direction from a datum position, the heater (6) is connected in parallel with the heater (5) whereas when rotated in the opposite direction from the datum position, the heater (6) is disconnected. Rotation of the spindle (9) in either direction from its datum position causes the cam (8) to move the contact 2 in the same direction in relation to the bi-metallic strip (4) and contact 3. <IMAGE>

Title: Freeze-dried coffee with a roast and ground appearance
Inventor: LAUDANO RAYMOND J
IPC: A23F5/36
Filed: 1983-03-18
Abstract: The coffee is produced by (a) slowly freezing the lower portion of a layer of aqueous coffee extract while leaving the upper portion not completely frozen; (b) instantly freezing the upper portion by spraying a cryogenic fluid, preferably liquefied nitrogen, on to it; and (c) freeze-drying and grinding (in either order) the frozen coffee extract. The combination of slow and fast freezing gives a frozen coffee extract comprising dark and light layers, giving on grinding, particles of different colours, which when mixed, simulate the appearance of roast and ground coffee.

Title: Combined thrust and radial ball bearing
Inventor: MCGUFFIE MICHAEL JOSEPH
IPC: F16C19/14
Filed: 1983-03-24
Abstract: A combined thrust and radial ball bearing comprises a pressed metal cup (90) in which is loosely-mounted a pressed metal annular thrust washer (96) which contacts a plurality of balls (98). The thickness of the thrust washer and the diameter of the balls are chosen so that an axial clearance  (101) between the metal cup and the thrust washer is provided in response to an axial force applied to the shaft 10 in a leftward direction. This bearing is a modification to those shown in UK Patent specification No. 2095770A. In another modification, Fig. 2, a third thrust washer is disposed between two sets of ball bearings which are themselves disposed between two thrust washers. <IMAGE>

Title: Tamper-resistant hypodermic syringe
Inventor: BUTTERFIELD IDA MAY
IPC: A61M5/50
Filed: 1983-03-28
Abstract: To prevent pilfering by insertion of a hypodermic needle through the soft body 16 of the piston into the fluid 14 contained in tubular body 12, an impenetrable washer 26 is embedded in the piston. The outer periphery of the washer is close enough to the body 12 to prevent passage of a needle. The portion 17 within the washer guarantees the integrity of the piston body 16 and is protected against penetration by the screw-threaded insert 18 for coupling to an actuating rod. In other constructions the barrier is a flange on the insert or a head of increased diameter. Where a separate non-retractable stopper is used in front of the piston the barrier can be attached to its rear face. <IMAGE>

Filed: 1983-07-08
Abstract: A pressure transducer device for an electronic musical instrument includes upper and lower support members 416,418, first spacer 420 between the upper and lower support members 416,418 and a resiliently deformable diaphragm 424 attached about its periphery to the upper support member 418 via a second spacer 422. A center region of the diaphragm 424 laterally spaced from the second spacer 422 is adhesively attached to a central region of the upper support member 418 so that the upper support member 418 moves inwardly and outwardly in response to the movement of the diaphragm 424. A pair of conductors may be disposed on the support members 416,418 to face one another. A pressure responsive semiconductor composition 446 disposed over the conductors provides a contact resistance across the pair of conductors which varies with the amount of pressure force exerted against the diaphragm.

Title: Improvements relating to garden cutting tools
Inventor: WILSON GRAHAM JOHN
IPC: A01D34/84
Filed: 1984-07-30
Abstract: A cutting tool comprises a body (1,5) which houses a fan (23) which can be driven by a motor (19). The fan (23) is arranged to draw air along a flow path extending through the body from an inlet (7) to an outlet (9).

Title: Fusible electrical resistor
Inventor: BRODIE DUNCAN GEORGE
IPC: H01H85/00
Filed: 1984-08-15
Abstract: A fusible electrical resistor comprises a planar electrically insulating substrate 2 supporting a film electrical resistance element 1 provided with electrically conductive terminals 3, 5 and 4, 6, the resistor being arranged to be connected by the terminals in an electrical circuit and operative such that when a particular power level in the resistor is exceeded due to application of an excessively high current or voltage, thermal stress developed in the resistor results in fracture of the substrate 2 and consequent open-circuiting of the resistance element 1 and interruption of the circuit. The resistor is characterised in that a strip of material 7, e.g. a self- adhesive insulating tape, is adhesively secured to at least one major face of the substrate 2. The strip 7 is arranged to remain intact and adhered to the resistor when fracture of the substrate 2 occurs and prevents dispersion of fragments of the substrate material. <IMAGE>

Title: Telephone answering machines
Inventor: HASHIMOTO KAZUO
IPC: H04M1/65
Filed: 1984-12-27
Abstract: The present invention relates to an automatic telephone answering device with automatic switching means between an automatic answering mode and a 2-way conversation recording mode. When a telephone is put into an off-hook condition for a direct conversation with a calling party while the automatic answering mode is in a standby condition or in operation, such an off-hook condition is detected by a current detector means and the conversation is recorded on a recording tape without any limitation on time. When either party puts his telephone into an on-hook condition during the recording of the conversation, the current detector means or a voice signal detector means is operated to stop the recording operation, and then the device is automatically brought into standby condition for the next call. <IMAGE>

Title: Tone signal generating apparatus for electronic musical instruments
Inventor: ISHIBASHI MASANORI
IPC: G10H7/00
Filed: 1985-01-16
Abstract: Code data representing a plurality of note frequencies are stored in a ROM (4) and are selectively read out according to key operation of a keyboard (1). With the operation of a key, predetermined control data is also obtained, and this control data is cumulatively added to or subtracted from the code data as an initial value by using an arithmetic means, whereby a note frequency signal corresponding to the operated key is obtained.
