Title: Chlorine dioxide production
Inventor: KISSEL CHARLES L
IPC: B01J7/02
Filed: 1985-03-12
Abstract: Apparatus suitable for the production of chlorine dioxide solution of predeterminable concentration and volume comprises a reaction chamber 10 and a dilution chamber 20 and valve means 11, 12 and 21. The solution may be made by injecting the compounds through valve means 11 into the chamber 10 wherein reaction occurs while the chamber is closed by, for instance, valve 12, and after the reaction is complete the valve 12 is opened to allow the chlorine dioxide gas to become absorbed in diluent that has previously been introduced into dilution chamber 20 through valve 21, which is then closed. After absorption is complete valve 21 may be opened and the dilute solution discharged from the apparatus. <IMAGE>

Title: Roof construction
Inventor: WIKLUND PER
IPC: E04D3/366
Filed: 1985-03-28
Abstract: This invention relates to a roof construction, preferably intended to be arranged on a roof of a slight fall and comprising a plurality of supporting plate profiles (1:1') which are put on crossbars (6) or the like, said plate profiles (1:1') being placed in a certain spaced relationship. At roofs having a slight fall, so-called plane roofs, it has so far been impossible in principle to use outer roof covering, as inleakage of water has been a great problem. The invention is characterized in that channeled plates (8) are laid on the supporting plate profiles (1:1') and that a condensate bar in the form of a disc (15) is arranged under each plate (8) at some distance from this, the disc (15) connecting with the plate profiles (1:1').

Patent GB-2206199-A (GB)
Title: Storage heater
Inventor: ELLIS GORDON
IPC: G05D23/275
Filed: 1987-06-23
Abstract: A control means for automatically controlling the charge and discharge rate of an electrical storage heater of the type, for example, which uses cheap, "off-peak" electricity to charge, and which discharges during periods when electricity is relatively expensive. The rate of discharge is controlled by way of input and output setting means, and a damper 19 pivoted on a temperature responsive control arm 21; thereby avoiding the use of complex charge sensing devices. The controller is capable of "over-riding" manual temperature settings, and is designed to operate, so that, should the heater not fully charge, it automatically discharges at a correspondingly lower rate and therefore for a longer time; and vice versa. The preferred embodiment operates by way of mechanical setting and thermostat means. Provision has also been made for an alternative more sensitive control means (see Fig 3), which has a cam at one end. <IMAGE>

IPC: G11B19/02
Filed: 1987-08-13
Abstract: A data recording device comprises a case containing a record (disc), the case having an identifying symbol 16 of a recessed emboss formed thereon which engages an identifying symbol 24 (Fig. 3B) of a projected emboss in the disc drive. If the embossed identifying symbols are not mutually compatible, the floppy disk is rejected and data-write or read prohibited. The arrangement counters disc - disc drive incompatibility, and unauthorised recording/playback. The operation of loading detection switch (31) and P.E. sensor (32) is detailed (Fig. 4, and Fig. 3c). The characters may have different depths (Fig. 2), and recessed pattern portions corresponding to the deeper characters may be provided in the further embodiment of (Figs. 5A, B). An area of the ID symbol (16") includes a conductive film (50) (Fig. 6) which engages table (54) (Fig. 7) with I.D. protrusions (56) and electrodes (58). A large through-hole allows normal positioning (Fig. 8B) but not the required short-circuit detection. An IC card may be provided (Fig. 9). TV game apparatus is specified (Fig. 1). <IMAGE>
Patent GB-2193866-A (GB)
Title: Data compression method and apparatus
Inventor: WILLIAMSON DR JAMES HUNDITH
IPC: H03M7/30
Filed: 1987-07-22
Abstract: A data compression system automatically assigns identifying tokens to the data as it is processed, and uses these tokens to reference later parts of the data. The tokens represent the combinable pairs of data units and may themselves be combined. Thus each repeated sequence of data units require half the previous number tokens to represent it as compared with its previous appearance. The set of stored tokens built up during encoding, and are correspondingly available for decoding. The encoding process can be adjusted for maximum compression or for faster throughput, in which case the partially compressed files can be processed later to compress them further. The decoding stage needs no prior knowledge either of the possible content of the data nor of the tuning parameter employed during the compression. When applied to data sequences containing a high degree of redundancy, e.g. in image compression, the invention can give a logarithmic compression factor for significant sections of the message. <IMAGE>

Filed: 1987-08-18
Abstract: A heat exchanger arrangement for a gas turbine engine comprises a first supply duct (32) to supply cooling fluid to a heat exchanger (34) from an intake (30) and a second outlet duct (36) conveys the cooling fluid to an exit nozzle (38). A first valve (40) controls the flow of cooling fluid through the second outlet duct (36). An auxiliary coolant fluid supply provided to supply cooling fluid to the heat exchanger (34) when there is no pressure difference between the intake (30) and the exit nozzle (38) comprises a fan (46) which draws fluid through a third duct (44) from a second intake (42) and supplies it via the second duct (36) to the heat exchanger (34). The first valve (40) is closed and a second valve (48) which forms an aerodynamically smooth surface on the second duct (36) is opened to produce a reverse flow of coolant fluid which is discharged from intake (30). The auxiliary coolant fluid supply does not introduce structure into the heat exchanger arrangement to impair its normal efficiency. <IMAGE>

Title: Poultry drinker
Inventor: FORSTER ROY E
IPC: A01K39/022
Filed: 1988-03-16
Abstract: A poultry drinker comprises a generally cone shaped body (42) having an annular drinking trough (44) at the periphery thereof, the body being supported by a main spring (36) and arranged to actuate a pressure-reducing valve in dependence upon its vertical position so as to maintain a substantially constant water level (50) in the trough. Water flows initially downwardly to a valve located within the body (42), then back up to at least one aperture (46) at or near the top of the body, then down into the trough (44). Such an arrangement, with the valve being positioned adjacent the water level (50) enables the vertical height of the drinker to be kept small, while at the same time allowing the use of the high pressure valve. <IMAGE>

Title: Performing raster operations on patch formatted pixel data
Inventor: TREVETT NEIL FRANCIS
IPC: G06T1/20
Filed: 1988-03-23
Abstract: A system and method for performing raster operations in a patch access environment utilizes two or more source patches 502, 504, 506, 508 to produce an X shifted destination patch 512. Even though the present invention operates in a patch access environment, it can form an X shifted destination patch by merging groups of pixels not residing within the same patch boundaries. The X shifting and merging used to form the X shifted destination patch can be done on a patch plane basis or on a patch basis. The X shifting and merging effectively combines preselected contiguous columns of contiguous patches. Boolean or arithmetic operations can be performed between the X shifted output patch and pre-existing data within a destination patch area so as to produce the X shifted destination patch. <IMAGE>

Title: Conditioned air egg incubator and method of operation
Inventor: LEMONNIER YVES
IPC: A01K41/00
Filed: 1988-07-22
Abstract: The incubator has at least one incubation chamber 2 mounted at the side of an air-conditioning chamber 17. A centrifugal fan 11 conveys a flow of sucked air into the central zone and delivers it towards the peripheral zones. The direction of rotation of the fan 11 for conveying air into the suction chamber 2 from the air-conditioning chamber 7 is periodically reversed. The air flows F returning to the central zone from the incubation chamber 2 along the axis of the centrifugal fan are accelerated by a helical fan 16 to give them the same speeds as the peripheral flows. A programmer 14 controls the speed of the fan 16 and the operation of water sprayers 18 to ensure uniform thermal and hygrometric conditions for all the eggs. <IMAGE>
