Abstract: Apparatus for the continuous or semi-continuous washing of roller towels or other elongate webs of textile material comprises a 'J'-box or soak tank (4), a vibratory dry sieve filter (16) arranged to separate fluff, lint, dirt and the like from rinsing water, a rotary perforated scroll (22) located in a scroll tank (55) that contains hot rinse water, the interior of the rotary scroll (22) being subject to a source of suction, stacks of rotary drying cylinders (27) and a magazine scray (64). The mouth of the 'J'-box or soak tank (4) is provided with a guide assembly and with a grooved driving roller (3) and a cooperating displaceable roller (31). The rollers (3) and (31) are grooved and the grooves receive rods of a guide assembly in such a way that, during use of the apparatus, a towel or other elongate web passing between the rollers and between co-planar pairs of rods of the guide assembly will be concertina-folded into the box/tank (4) until a weight-sensitive switch is tripped when said box/tank (4) is substantially full. The speed of movement of a towel or other web through the apparatus is such that each region thereof will remain in a concertina-folded condition in the 'J'-box or soak tank (4) for a sufficient length of time to become thoroughly soaked by heated aqueous detergent solution or other liquid contained therein. The apparatus is used in such a way that dirty towels or other webs are tack-stitched or otherwise temporarily connected to one another adjacent to a supply hopper (28) of the apparatus and are disconnected from one another after the tripping of a detector switch (66) by such a temporary connection adjacent to a re-winding mandrel (65) for the successive towels or other webs. <IMAGE>

Title: The watergate
Inventor: BROWN PHILIP ALAN
IPC: E06B9/00
Filed: 1981-08-13
Abstract: The watergate is a simple gate device to afford complete protection from seasonal and flash flooding for buildings in flood prone areas. It consists of a shaped rigid or semi-rigid gate which is inserted into a groove or edging strip fixed to the doorway or low window. A sealing strip in the edging strip or groove renders the gate watertight. Air vents around the building would be rendered watertight by the fixing of a small gate held in place by cavity fittings. <IMAGE>
Patent GB-2085992-A (GB)
Title: Improvements in or relating to releasable tube couplings
IPC: F16L37/092
Filed: 1981-10-26
Abstract: A releasable tube coupling comprises a body (1) having an externally screw-threaded terminal portion (2) to which an internally tapered sleeve (9) is coaxially secured by means of an internally screw- threaded coupling member which may be integral with the sleeve (9) or, preferably, is in the form of a separately formed coupling nut (5). The sleeve (9) houses a sealing ring (15) and a pipe-gripping collet (18). If a tube (23) coupled to the device is accidentally pulled, for example, the arms of the collet (18) co-act with the tapered internal surface (25) of the sleeve (9) and exert an increased gripping force on the tube (23) thus preventing withdrawal thereof. However, if it is desired to withdraw the tube (23) from the coupling the collet (18) is pushed towards the body and the tube (23) is pulled out. <IMAGE>

Title: Ventilation of Agricultural Buildings
IPC: G05D23/20
Filed: 1981-11-30
Abstract: An agricultural building installation suitable for storage of produce or housing of livestock is divided into a plurality of zones, each having at least one temperature sensor 30, and a respective air damper 17. A control device monitors the outputs of the sensors 30 in each zone, one at a time, and then causes air dampers 17 to be opened or closed, to increase or decrease ventilation to a zone. Ventilating air may be pumped into a central duct 11 extending through the building, passing into underfloor passages through opened dampers 17, and then rising upwardly through openings in the floor, so as to pass through stored produce. Alternatively, the dampers may be provided in external walls so as to control natural flow of ventilating air through the building. Extra sensors may be provided for the bottom and top of stored produce (27 and 28) respectively, internal roof temperature (29) and for incoming air temperature (26), the control apparatus adjusting the dampers 17 in dependence upon the outputs of all the sensors. Each zone may have a plurality of sensors 30 the output of which is averaged, and a sensor may be provided for external ambient air temperature. <IMAGE>

Title: Liquid dispenser
Inventor: BUNCE ROGER ABRAHAM
IPC: B65D47/06
Filed: 1982-10-21
Abstract: In medical tests on biological fluids it is frequently necessary to dispense a quantity of fluid from a first vessel into a second vessel in order to investigate the fluid. As well as accurate dispensing, there is often the requirement that none of the fluid should escape into the atmosphere; as in the instance when the fluid is blood serum infected with dangerous micro- organisms. The dispenser comprises a first vessel having a cap with two nozzles (1,2) extending from it, the nozzles being typically of equal length and internal diameter. For dispensing, the first vessel when inverted rests on the second vessel (20). The fluid flows down one nozzle and air up the other until the fluid level in the second vessel reaches the nozzles, when flow stops. On removal of the first vessel, no further fluid escapes from the nozzles, provided they are proportioned, in correct relation to the fluid to be dispensed, and to the ambient temperature. <IMAGE>

Title: Hydraulically actuated semiconductor wafer clamping and cooling apparatus
Inventor: BRAMHALL ROBERT BILLINGS
IPC: H01L21/673
Filed: 1982-11-11
Abstract: Apparatus for hydraulically clamping a semiconductor wafer 8 in a vacuum chamber during ion beam processing includes a compression plate 12 attached to a housing 14 and a movable pressure plate 18 coupled by a fluid-containing bellows 20 to the housing. When a predetermined pressure is applied to the fluid, the bellows 20 expands and causes the wafer 8 to be firmly clamped against the compression plate 12. A pliable, thermally conductive pad 16 between the wafer and the pressure plate facilitates transfer of thermal energy from the wafer to the pressure plate. The fluid is circulated through a heat exchanger and the bellows to provide efficient cooling of the pressure plate. <IMAGE>

Filed: 1982-11-25
Abstract: A control system for use with articulated arms, such as manipulator arms carried by submersive craft, agricultural backhoes and cargo handling cranes and diggers has one or more joints or functions. The force applied to a rigid non-movable master control (1) is sensed by means of strain gauges (9, 11, 13, 15). A pair of strain gauges is provided for each joint or function. Each pair of strain gages is associated with a gauge amplifier (17) and a servo amplifier (19). The output voltage signal from the gauge amplifier is proportional to the direction and value of forces applied to the master control by the operator. The circuitry (17, 19) associated with each pair of strain gauges drives an electric motor (21) which, in a preferred embodiment, drives a hydraulic pump (25). <IMAGE>
