Patent GB-2114321-A (GB)
Title: Electric rice cooker
Inventor: OOTA HIROYUKI
IPC: A47J27/00
Filed: 1983-01-31
Abstract: An electric rice cooker is disclosed which performs auxiliary cooking such as "twice cooking" by changing the operating time of auxiliary cooking in accordance with the actual cooking amount, immediately after the main cooking is completed. The actual temperature of a kettle (18) which contains rice and water and which is detachably mounted in a thermal insulating frame (10) is measured by a thermistor (24). Upon deenergization of an electric heater (20) after main cooking is completed, the actual kettle temperature decreases. A time interval for the kettle temperature to go from a first temperature at the completion of main cooking to a second temperature is closely related to the actual cooking amount. The auxiliary cooking time interval is determined by a control circuit arranged in a case (28) in accordance with the time interval described above. <IMAGE>

Patent GB-2114503-A (GB)
Title: Extrusion apparatus and methods of splicing ropes or cables utilizing such apparatus
Inventor: THOMSON IAN MAIN
IPC: B29C48/34
Filed: 1982-07-27
Abstract: An extruder die for plastics material has a predetermined cross-sectional area and can be deformed to change this cross-sectional area to allow variation of the cross-section of the extrusion. This finds particular application in the re-covering of a spliced plastics covered rope where the diameter of the rope increases between an uncovered spliced section and the covered remainder of the rope. Such a die can be used to extrude a plastics covering over the splice section and, at the end of the uncovered section, expand over the existing cover to provide a continuously covered rope.

Title: Margarine and the like spread with natural butter flavour
Inventor: BAKAL ABRAHAM I
IPC: A23L27/20
Filed: 1983-06-20
Abstract: Margarines or like spreads are provided with natural butter flavour by incorporating therein oil soluble lipolyzed cream or butter oil (obtained by treating fresh cream with lipase enzymes) and water soluble starter distillate (which is a mixture of flavour compounds distilled from cultured reconstituted skim milk) in an amount sufficient to impact the butter flavour to the spread. The proportion of water solution component to oil soluble component should be between 1 part water component per each 2-20 parts oil soluble component. It is necessary for the water phase to be distributed throughout the oil phase. This can be accomplished either by mixing the oil and water phases with a carrier such as maltodextrin and drying, which causes the phase to become encapsulated, or by emulsifying the two phases by means of an emulsifying agent.

Patent GB-2164523-A (GB)
Title: Electronic alarm sounder
Inventor: MITCHELL HOWARD JOHN
IPC: G08B3/10
Filed: 1984-09-15
Abstract: A system particularly for use with a rocking armature type of alarm sounder (1), enables remotely generated speech or other sound signals to be emitted in addition to normal alarm sounds. A remote transmitter (9) superimposes amplified speech or other sound signals onto a D.C. carrier and transmits them over unscreened wires (7,11) to a receiving circuit (10), the signals being maintained within a frequency bandwidth centred around a centre frequency of natural resonance of the sounder (1). A.C. coupling and attenuation of the received signals is effected in the receiver (10) which also includes a differential amplifier (17). The speech signals after amplification are emitted by the sounder (1). The wire (7) is common to the power supply and the speech or other sound signal transmission. The arrangement minimises problems due to electrical noise and radio-frequency pick-up on the unscreened wires (7,11). The receiving circuit (10) and a generator (2) for the sounder (1) are arranged to be activated by voltages of opposite polarity and the required operating mode is selected by reversing the polarity of the supply voltage. <IMAGE>

Title: A series/parallel conversion circuit and display driver
Inventor: TANAKA SHINJI
IPC: H03K21/08
Filed: 1985-01-28
Abstract: A series/parallel conversion circuit for use in a display driver circuit includes a plurality of first latch circuits (6) which latch a serial data signal, one bit or several bits at a time, the output of a counter (4) which counts a clock signal being decoded (5) to activate the first latch circuits (6) in succession to latch one bit or several bits of serial data simultaneously. After data has been latched into all of the first latch circuits, the data is output in parallel using second latch circuits (2). This reduces the number of gate circuits activated, and therefore reduces complexity and power consumption. <IMAGE>

Abstract: The combination container consists of a concentric double receptacle, wherein a mounting (5) for the second receptacle (2) is attached at the periphery of the aperture of the first receptacle (1) by means of notches or undercuts, eg in the manner of a bayonet closure. This mounting (5) is provided with a central aperture (10) having an internal thread (11) which fits onto an external thread located on the neck of the second receptacle (2). Perforations or apertures for pouring out the liquid contained in the first receptacle (1) are provided in the mounting (5). Moreover, the apertures of the first receptacle (1) and the central aperture in the receptacle (2) can be closed by a common screw cap (12). The first receptacle (1) consists as a rule of a canister of square or rectangular cross-section, while the second receptacle (2) can be a commercially available plastic bottle of the same height. After filling the two receptacles with different liquids, eg crop protection liquids, a metal laminated plastics film (14) may seal the apertures. Spikes (15) on the screw cap maybe used to pierce the film (14), a sealing disc (18) of foamed polyethylene carried by the cap acting to seal the inner receptacle and prevent any unintentional mixing of the liquids. <IMAGE>

Title: Test plate assembly defining discrete regions on a microporous membrane with low boundary distortion
Inventor: FERNWOOD GEORGE G
IPC: G01N33/48
Filed: 1986-05-12
Abstract: A biochemical test plate assembly for use in multiple simultaneous contact tests arranged in a fixed array of discrete regions on a single microporous membrane sheet provides less distortion of the boundaries of these regions than do pre-existing assemblies. The assembly contains two apertured plates 11, 13; an apertured gasket sheet 17 and a microporous membrane 19, both placed between the apertured plates; and a third plate 15 for placement beneath the apertured plates, having a recess which serves as a reservoir for liquids passing through the membrane. The improvement resides in the enclosure of the lower apertured plate by the upper apertured plate and a recess in the base plate, thereby sealing the lower apertured plate and the microporous membrane off entirely from the atmosphere. This eliminates evaporation of moisture from the edges of the membrane, and any lateral diffusion of biochemical species which might occur as a result due to capillary attraction. The floor of the base plate may slope towards a vacuum port 46. <IMAGE>

Title: Token handling
Inventor: EGLISE DAVID
IPC: G07C9/00
Filed: 1987-03-10
Abstract: A token handling device transmits, using an electromagnetic carrier, data, clock pulses and power to a token. The token could be used in transactions in place of coins, or alternatively could be used for identification purposes in other areas. The token receives power from the device and has a non-volatile writable memory and is arranged to perform, following power up, one of a plurality of sequences of operations dependent upon flag data stored in the memory, at least one of those sequences resulting in a change in that flag data. Data stored by the token could be used to change the way in which the token handling device operates. The token handling device may for example form a vending machine, and the token could be used to alter the pricing of goods vended thereby. The token handling device may be combined with a coin validator, in which case there is preferably a common path from an entrance slot for carrying both the tokens and the coins to appropriate testing apparatus.
