Title: Improvements in or relating to the covering of playing and other surfaces
Inventor: SPRY ERNEST HAROLD
IPC: A63C19/12
Filed: 1982-11-23
Abstract: In order to protect a playing area 1 from the effects of rain or snow, a cover 6 made of flexible and waterproof sheeting is drawn over the playing area 1. A substantially leak-proof connection is established between the cover 6 and a drainage channel 2 surrounding the playing area 1 by nipping the edges of the cover 6 between removable gutter members 27 and an inturned flange 35 on one side of the channel 2, the gutter members 27 being snapped into position beneath the flange 35 and a further inturned flange 34 on the opposite side of the channel 2. Warm air is then introduced under pressure between the playing area 1 and the cover 6 so as to inflate the cover 6 and cause it to take up a convex profile above the level of the playing area 1. <IMAGE>

Title: Measuring the feeding of animals
Inventor: CRANE RAYMOND GRANVILLE
IPC: A01K5/02
Filed: 1984-03-21
Abstract: For measuring the amount of food, in the form of powdered milk in water, taken by a calf over a period, the liquid food is pumped by a peristaltic pump 11 from a receptacle 23 to a reservoir 24 via tubing 21, 14 and 22, the calf using a teat 26, connected to reservoir 24 by tubing 25, to suck the food from the reservoir 24.

Filed: 1984-05-21
Abstract: In a method of preventing unauthorised copying of documents or the like each sheet is preprinted or overprinted with a normally barely visible or non-visible dye which fluoresces when copied, unless a "copyright fee paid" button of a special copying machine is pressed to effect illumination of documents for copying without stimulating the dye.
Patent GB-2166243-A (GB)
Title: An overpressure protector for pressure gauges
Inventor: RUESSE ROLF
IPC: G01L19/06
Filed: 1984-07-07
Abstract: A pressure transmitter 1 is connected to pressure source piping 2. A moveable seal 3 separates measured fluid A from gauge fluid B. The transmitter 1 is connected to a pressure gauge 8 and a gas filled accumulator 6 containing a piston 7. When gauge fluid B pressure exceeds the pressure of the gas C in the accumulator the piston 7 will move and gauge fluid B will enter accumulator C. This allows the seal 3 to expand and close valve 4 thus preventing any further pressure increase in medium A from reaching the gauge. <IMAGE>

Patent GB-2167175-A (GB)
Title: Heat exchanger
Inventor: CROSS DONALD ANDREW
IPC: F28D9/00
Filed: 1984-12-10
Abstract: A heat exchanger is made up by the formation of sub-assemblies of plate (1,2,3) and spacer (1a,1b,2a,2b,3a,3b) and building up a pack of such sub-assemblies by successively welding through the plate to secure the plate (2,3) to the spacer (1a,1b,2a,2b) of the preceding sub-assembly. For this purpose, it is necessary for the peripheral spacers (1b,2b,3b) to be successively offset from each other for access to be obtained for through-the-plate welding. in accordance with the present invention, the successive peripheral spacers (1b,2b,3b) overlap, leading to increased strength of the pack and also to an economy in plate size for a required area of the heat exchange zone. <IMAGE>

Patent GB-2166482-A (GB)
Title: Mobile plant for the modification of clay and manufacture of modified-clay building products for rural development
Inventor: PAULUS MARCEL JACOB
IPC: B28B15/00
Filed: 1985-05-29
Abstract: This invention is concerned with the design of a complete production unit consisting of a range of skid-mounted machinery and other equipment which can be conveniently transported to various sites in rural districts where both clay and operating space are readily available for on-site production of modified- clay building materials featuring qualifications which comply with contemporary rural building requirements. This range of machinery constitutes the basic requirements for the operation of a unique mobile plant which can be brought to distant locations and temporarily installed to produce clay building materials for foundations, walls, floors and roofs. This eliminates the need to transport conventional building materials from central districts or far-away factories, thus avoiding heavy transport charges and inevitable delay. Through work conducted in this field where simple hand-operated equipment was used to modify clay and make the early specimens of these clay products, I was able to determine the right proportion of water and binder added to the prepared dry clay, and to set down specifications for the machinery required to perform the modification and manufacturing process with accuracy which ensures the production of modified-clay building materials to the required standards, and at a moderate cost.
Patent GB-2159874-A (GB)
Title: Detecting position of flip-up and sliding roof panel
Inventor: KALTZ MILTON C
IPC: B60J7/05
Filed: 1985-06-05
Abstract: A sliding panel assembly (Fig. 2) for a vehicle includes a panel movable by thrust-transmitting cables (64) to lower the panels' rear edge and slide it open or to flip-up the panel by pivoting it about its front end. The cables are driven by a motor (58) controlled by passenger-actuated switches. When a cable (64) moves the panel to its closed position, it moves an attached position detector (144, Fig. 11) to a central position to actuate a switch (150) to allow the passenger to switch the motor. When the cable moves the panel to its flip-up or to its slide-under position, it moves the detector (144) to allow the switch to be reversed and thus prevent a passenger incorrectly operating the motor. A further detector type is described (Fig. 11, not shown). A time delay may delay passengers switching the motor after the panel is closed. <IMAGE>
