Title: Microwave detection apparatus
Inventor: FITZPATRICK JAMES
IPC: G01S13/04
Filed: 1989-08-15
Abstract: Apparatus for detecting the presence or absence of objects at a predetermined location. particularly suitable for use in a hostile environment such as a nuclear fuel dismantling cell, comprises a microwave transmitter/receiver (34), a first waveguide (24) for directing a transmitted microwave signal to the location, and a second waveguide (26) for directing a return signal to a detector (40) forming part of the transmitter/receiver.

Title: Control of microwave heating apparatus to avoid overvoltage on starting
Inventor: ISHIYAMA KUNIO
IPC: H05B6/66
Filed: 1989-12-18
Abstract: During normal operation of a high frequency inverter 3, 4 supplying a magnetron 5 via a step-up transformer 2, the duration of each on period of a switch 3 in the inverter is controlled by a feedback circuit 21, but on initial energisation of the heating apparatus a limiter circuit 22 causes such on periods to be relatively short for an initial time set by a timer 23 and chosen in dependence on heating characteristics of the cathode of the magnetron. The arrangement avoids excess voltage at the transformer secondary before the magnetron starts to oscillate. The feedback circuit 21 may be responsive to magnetron anode current, or to magnetron power, (Fig 7).

Title: Flavorful frying oil with long frylife
Inventor: HALSTEAD LARRY DEAN
IPC: C11B3/14
Filed: 1990-08-01
Abstract: A frying oil composition is made from 80% to 99.9% deodorized edible oil (most preferably soybean oil) and 0.1% to 20% undeodorized highly flavored edible oil (most preferably peanut oil). The deodorized oil of the composition undergoes a high temperature deodorization process to impart excellent frylife to the oil. The undeodorized highly flavored oil is blended with the deodorized oil. The resulting frying oil composition is highly flavored and has the same excellent frylife as the deodorized oil.

Title: A resettable thermostatic control valve
Inventor: HUXTABLE MARK ASHLEY
IPC: G05D23/02
Filed: 1990-08-04
Abstract: A resettable thermostatic control valve unit has a control valve (1) including a control member (5) movable from an extended position to a retracted position against the action of an internal spring, and a valve actuator mechanism comprising a bracket (6) carried by the valve, a spring clip (8) carried by the bracket (6) and engageable with the control member (5) to retain the control member (5) in its retracted position and a shape memory alloy member (9) carried by the bracket (6) and engageable with the clip (8). If the member (9) is heated above a predetermined temperature it urges the spring clip (8) away from the position in which it retains the control member (5) in its retracted position, causing it to move to its extended position where it remains upon the temperature falling below the predetermined level. In Figs. 2A-C (not shown) over-heating of the member (9) causes rotation of the control member (5) to release a latch and permit axial movement of the member (5). In Figs. 3A-B (not shown) expansion of an SME spring (24) permits a spring clip (25) to move into the path of the control member (5) and thus prevent its return movement. <IMAGE>

Title: "A method and apparatus for crushing cans"
Inventor: BEACH-THOMAS ANTHONY WILLIAM
IPC: B30B9/32
Filed: 1991-01-05
Abstract: The method comprises folding the end panels 31 of the can 21 inwardly towards one another until they and the portions of the can's main body connecting them are substantially flat. As shown, the can 21 rests against a fixed abutment surface 17 between pivoted crushing arms 28. The crushing arms 28 are swung towards one another, e.g. by operation of a lever arm, or power means, which may also operate a creasing finger 33 to deform the middle of the can 31 to facilitate crushing. The flattened can then falls through a gap 20 adjacent the surface 17 and into a collecting receptacle. The apparatus may form part of a vending apparatus. An array of flexible bristles 18 will be insufficient to support the weight of an article heavier than an empty can which will fall past the bristles 18 into a collection bin 30. Details of a metal casing housing the apparatus are shown in Figure 1. Various modifications are disclosed e.g. to differentiate between aluminium and steel cans. <IMAGE>

Title: Container with sliding lid
Inventor: LOFTUS STEPHEN CLIVE
IPC: B65D43/12
Filed: 1991-11-08
Abstract: A container 10 for slidably receiving a resilient flexible lid comprises first and second lid support surfaces 14 which extend along opposed sides of the mouth 16 of the container 10. Retaining projections 18 are spaced above the surfaces 14 to define spaces between the projections 18 and the surfaces 14 for receiving the edges 22 of the lid 12. Abutment means 24 for retaining the lid are spaced from the retaining projections 18 at one end of the surfaces 14 and the lid is sufficiently flexible to be deformable against its resilience away from the surfaces 14 at the said one end thereof and clear of the abutment means 24. This allows the deformed lid to slide along the surfaces 14 and, after deforming, pass the abutment means 24 to be wholly or partially removed from the container. <IMAGE>

Title: Data storage techniques.
Inventor: KEMP MICHAEL JOSEPH
IPC: G10H7/02
Filed: 1992-02-14
Abstract: A plurality of data segments such as sound recordings, are stored on a mass storage device (21). A first portion of each sound segment is stored in an i.c. memory (12) so as to be instantly available. Addressing circuits (20, 5) is provided and is operable in response to signals from a controller (10) to read first the portion of a data segment stored in i.c. memory (12) and then the portion on the mass storage device (21) so as to give substantially simultaneous playback of data. It is desirable to be able to simulate fast playback of data and in order to achieve this data is recorded in a mass storage device (120) with every nth sample in the data stream also being recorded in a fast block (51). As desired playback speed is increased only data from the fast block (51) is replayed.

Title: Treatment of effluents
Inventor: COSTAIN ADRIAN ERIC
IPC: C02F1/32
Filed: 1993-11-09
Abstract: In a non-biological treatment of effluent, such as raw sewage and liquid industrial waste, suitable for use in remote locations, solids are separated from the effluent by sedimentation followed by membrane filtration 14 to provide a filtrate which is acceptable for environmental discharge. The membranes may be formed of ceramics or polymers. The separation steps may be optimised to take place naturally, or may be assisted by the controlled addition of chemicals such as flocculating agents and the treatment may also include ultraviolet sterilisation to kill any bacteria in the final filtrate. The components of the apparatus are designed for use in locations where space is at a premium and may be demountable to enable assembly and disassembly in confined quarters, such as those on board a ship. A metal mesh filter 12, which may be a separate unit or located in sedimentation tank 3, is located upstream of membrane filter 14. A macerator may be included upstream of tank 3. <IMAGE>

Title: Leakage-sound detecting apparatus
Inventor: TORINZUKA YUKIO
IPC: G01M3/24
Filed: 1993-12-02
Abstract: A leakage-sound detecting apparatus is provided for efficiently detecting water leakage in a plastic pipe by increasing sensitivity to a low frequency sound component and efficiently reducing stray noise, as well as protecting a piezoelectric element. To this end a detection portion 2 and a pedestal portion 3 are connected through a mechanical resonant member 4 formed of a soft material. A low frequency sound component is amplified by the resonant member 4, and high frequency components are substantially attenuated. In an alternative arrangement (Figure 8) a detection portion 22 and a mechanical resonant member 24 mounted on a pedestal portion 23 are connected through a buffer portion 31 having a buffer member 35 is arranged therein. When a shock is applied to the bottom of the pedestal portion 23, due to the apparatus being dropped for example, the buffer member 35 is compressed, and no overload is applied to a piezoelectric element 26. <IMAGE>
