Inventor: YOSHIDA SATOSHI
IPC: G10H1/34
Filed: 1989-04-25
Abstract: An electronic musical instrument copying a so-called stringed instrument and capable of detecting a depression state of a fingerboard (9) on the basis of an ON/OFF state of a plurality of contacts formed in the fingerboard (9) and thereby determining the pitch of a musical tone to be generated. The contacts may comprise a plurality of pairs of electrodes (15, 16) arrayed transversely to each string (5) as in Figure 3, and/or a plurality of pairs of electrodes (15, 16) arrayed between adjacent frets (10) as in Figure 11.

Patent GB-2231521-A (GB)
Title: Welding machine controllers
Inventor: DRUCKER RUDOLF
IPC: B23K11/11
Filed: 1989-05-16
Abstract: In a controller for electrical resistance welding machines, especially for spot welding using a welding transformer and a weld gun, a delay is preset in the reset line from the welding timer to the trigger that initiates the welding timer, so that the welding timer cannot be triggered to commence a fresh weld immediately the previous weld has been completed. The delay, which can be accomplished by an R.C. time delay network, is calculated to determine a maximum frequency of making welds at which sufficient cooling time exists between welds to render it unnecessary for the welding operation to be stopped periodically for a prolonged cooling period to avoid over-heating. <IMAGE>
Patent GB-2232759-A (GB)
Title: Isolation extraction systems
Inventor: COLES TIMOTHY PAUL
IPC: A01K1/03
Filed: 1989-05-16
Abstract: In isolation units, each animal is kept in a small deep-tray cage with a mesh top, positioned adjacent the rear wall of the isolation unit. The air passing into each cage is extracted therefrom independently of the air passing into and through any other cage. A plenum chamber (18) is directly connected to the isolation unit's extraction system (26 etc). Each cage (21) has a short exit pipe (24) that plugs (preferably as a friction fit) into one of a series of corresponding apertures (as 19) in the plenum chamber wall (16). This arrangement provides each cage (21) with its "own" air extraction system, essentially separate from that of any other cage. <IMAGE>

Title: A method for the cooling of a heat-sterilised food containing solid and/or semi-solid particles
Inventor: RAUSING HANS
IPC: A23L7/109
Filed: 1989-11-10
Abstract: A method for the cooling of a heated, e.g. heat-sterilized, flow containing particles of foodstuff character. The flow is separated into a high-particle and a low-particle fraction which is cooled separately and is used later as a cooling medium for the cooling of the high-particle fraction. The method is intended in the first place to be used in so-called aseptic packaging according to which the heat-treated, cooled foodstuff product, e.g. fruit soup, vegetable soup, meat broth etc. is packed in sterilized packing containers, or in packing containers manufactured from sterilized packing material, under aseptic packing conditions.
Patent GB-2244073-A (GB)
Title: Scale inhibitor in oil producing wells
Inventor: READ PETER ARNE
IPC: E21B43/22
Filed: 1990-05-15
Abstract: A method for inhibiting scale formation in oil producing wells comprises pretreating the rock formation of the near well bore area with a surface active agent and then a saline solution by injecting these down the well bore. Subsequently the formation is treated with a source of divalent cations such as calcium. An acid inhibitor in the form of a polyacrylic acid derivative, a phosphonate or a phosphinopolycarboxylic acid is then injected into the rock formation and allowed to soak in for a period of 24 hours. The inhibitor is retained on the surface area of the rock formation by means of divalent cationic bonds.

Title: Controlling or deriving direct current level of video signals
Inventor: ARMSTRONG DESMOND ROSS
IPC: H04N5/16
Filed: 1990-06-29
Abstract: A video signal is applied via a storage capacitor C to a comparator comprising long tailed pair of transistors T1, T2. A comparison is made with a black level reference VR and as a result transistors T1, T2 are switched to cause current mirrors IM1, IM2, IM3 to be operative or not for supplying current to or from the storage capacitor C. In the balanced condition when the current mirrors IM1, IM2 supply substantially zero current, current for the collectors of transistors T1, T2 are supplied by further current mirrors IM4, IM5. <IMAGE>

Title: Aircraft ground-handling vehicle
Inventor: JONES BERNARD CECIL EDGAR
IPC: B64F1/22
Filed: 1990-11-28
Abstract: The vehicle, for insertion between the wheels (15) of an aircraft undercarriage, includes a body (11, 12) and undercarriage trolleys (13) connected to opposing ends of the body. A chassis (1) is pivotally mounted with respect to the body. Independently driven and controllable wheels (4) are mounted on either side of the chassis (1). The chassis can be moved between a first position in which those wheels (4) are substantially parallel to the undercarriage wheels (15) and a second position in which the wheels are substantially orthogonal to the undercarriage wheels.

A locking mechanism (8, 9) such as a pinion in meshing engagement with the outer circumference of the ring bearing may be provided. The vehicle is particularly suitable for handling aircraft having tricycle undercarriages with fully castoring nose-wheels. Fine control of movement is achieved by differential drive of the wheels (4) while the pivot between the chassis (1) and body (11, 12) allows crab-wise manoeuvres.

Title: Gas turbine engine nacelle
Inventor: PATILLA RICHARD GRAHAM
IPC: F02C7/042
Filed: 1991-09-04
Abstract: A nacelle for a gas turbine engine 10 defines an air intake which is capable of meeting different engine airflow requirements. The nacelle comprises a secondary cowling 22, fixed upstream and in spaced apart relationship from a primary engine cowling 16, to define an annular passage 30 therebetween. Each of the cowlings, 22 and 16, have an air intake, 24 and 20 respectively, through which the mainstream flow of air passes into the engine 10. Depending upon the amount of airflow the engine 10 demands at different operating flight conditions air can flow in either direction through the passage 30. The flow in either direction through the passage 30 enables optimisation of both the internal and external nacelle requirements at different engine airflow requirements. In one embodiment the area of the annular passage 30 can be varied by pivotal movement of a downstream portion 28 of the cowling 22. <IMAGE>
