Patent GB-2074253-A (GB)
Title: Pressure control apparatus
IPC: H01H35/24
Filed: 1981-03-25
Abstract: A pressure control apparatus for controlling a pressure device that tends to overrun after disconnection from its power source has an electric pressure switch combined with a pressure limiting valve, the switch having a pressure member (19) slidable axially in a housing (38) and loaded by the force of a limiter spring (34), that acts on a part of an electric switch (57, 63:72) Figs 16 to 6 (not shown). In order to combine the pressure switch with a pressure limiting valve to relieve excess pressure produced by overrunning, the pressure member (19) is connected on its side remote from the electric switch (57, 63:72) with a valve member (1) of the pressure limiting valve (1, 2) and surrounded by a sleeve member (24) movable in the housing (38), arranged between the pressure member and the housing and on which the limiter spring (34) bears. Between the valve member and the sleeve member a pressure chamber (27a) is provided. The sliding movement of the sleeve member (24) is limited with respect to the valve member (1) by abutments (1, 33; 24, 29 and 70 respectively). <IMAGE>

Title: Gripper ring for a tube coupling
IPC: F16L19/08
Filed: 1980-08-28
Abstract: A gripper ring for a tube coupling, said coupling comprising a one piece or divisible nipple (1) and a sealing ring (2), said gripper ring (3) being adapted to be situated axially outside of the sealing ring (2) and having an external conical surface adapted to cooperate with a complementary conical surface inside the nipple (1) or inside an attached element (4) of the nipple (1), in order to cause compression of the gripper ring (3). The gripper ring relates to the problem of mounting a tube (5) in the coupling when the coupling is in its use condition, namely the problem to force the tube (5) through the gripper ring and the sealing ring without meeting a large resistance. This is achieved by the features that the inner surface of the gripper ring (3) is conical substantially in its entire length, and that the axially innermost end of the gripper ring (3) is tapered in such a manner that the sealing ring (2) is caused to expand when the gripper ring (3) is pressed axially against the sealing ring (2).

Patent GB-2091134-A (GB)
Title: Portable liquid sprayers
IPC: B05B3/10
Filed: 1982-01-11
Abstract: Liquid to be sprayed is held in a container 32 mounted on an intermediate portion 14 of an elongate handle 10. When a valve 24 is open, the liquid flows under gravity through a conduit 21 to discharge into an upwardly facing cup 20 secured to the vertical drive shaft 19 of an electric motor 18 at the front end 15 of the handle 10. The valve 24 is controlled manually with a control cable 28 which also controls the opening and closing of the on/off switch of the power circuit 36,37 for the motor 18, the power source being a battery 40 mounted on the handle 10. The cup 20 has downwardly and outwardly directed holes 45 through the periphery of its bottom wall 42 so that when the motor 18 rotates the cup 20, the liquid in the cup 20 is sprayed out from these holes 45. The handle 10 can be demounted from a wheeled frame 12. The holes 45 are all the same size and the rate of flow of liquid into the cup 20 is constant. The cup 20 is rotated at a constant rate and the spray consists of uniform droplets. The container preferably has an air inlet (56), Figures 7, 8 (not shown), controlled by a pressure-sensitive valve (57) which admits air to the interior of the container at a rate dependent upon the head of liquid pressure therewithin to thereby provide a uniform flow to the valve 24. <IMAGE>

Title: Filling nozzle structure
IPC: F16K23/00
Filed: 1982-02-12
Abstract: A filling nozzle structure 10 for use with filling units with suction and discharge strokes includes an elastic sleeve-like member 40 which, in the absence of discharge pressure at the nozzle structure inlet bore 31, closes off communication between the bore 31 at a valve body 21 to a recess 13 within a nozzle body 12. The sleeve- like member 40 when acted upon by the discharge pressure of the filling product in the bore 31 is distended and thereby opens up the communication through bores 24. Upon disappearance of the discharge pressure, the member 40 collapses again thereby closing off such communication and producing a suction effect by the formation of a suction chamber 60a between its external surfaces and the internal surfaces of the recess 13. Thus product in the nozzle outlet bore 14 communicating with the recess 13 is sucked back at each suction stroke of the filling unit. <IMAGE>

Title: Self-levelling suspension system
IPC: B60G17/016
Filed: 1982-03-23
Abstract: A sensor is associated with each suspension unit or coupled pair of units for adjusting the ride height of a vehicle, and each sensor gives an output that varies progressively with ride height. A control circuit, preferably microprocessor based, is arranged to   (i) read each of the outputs at least once, preferably in sequence,   (ii) select the output which corresponds to the sensed ride height that differs most from the desired ride height, and (iii) apply a correction to the suspension unit(s) associated with the selected output to adjust it/them towards the desired ride height.   The control circuit repeats (i) to (iii) until all the sensed ride heights are within acceptable limits of the desired height whereupon the system enters a so-called trim mode. In this mode corrections are based on a calculated ride height at a conceptual centre of height where height variations due to pitch and roll are minimal.

Title: The size reduction of oil seeds
Inventor: HUSSEIN ISMAIL HASSAN
IPC: A23L11/00
Filed: 1982-05-08
Abstract: Castor beans were treated with a freezing agent such as solid carbon dioxide, a mixture thereof with an organic solvent, or liquid nitrogen, prior to milling them in a grinder. The beans were solidified as a result of the freezing treatment so that there was no apparent oil loss when they were ground. The process was applied successfully both to whole and dehulled beans, as well as to other oilseeds, e.g. soyabeans, peanuts and sunflower seeds. It was possible to dehull soyabeans and to remove the skin of shelled and unshelled peanuts using this method, when freezing was conducted in a freeze dryer

Title: Asymmetric dichroic dye molecules having poly (arylazo) linking groups and bis-substituted aryl thiazl substituents
Inventor: HUFFMAN WILLIAM A
IPC: C09B35/50
Filed: 1982-06-23
Abstract: Asymmetric molecules having a plurality of arylazo linking groups, bis- substituted aryl thiazyl end groups, and either naphthyl, perimidine or julolidene end groups, are found to be dichroic dyes which form guest-host combinations with nematic liquid crystals. These dichroic dyes have absorption maxima at wavelengths greater than 600 nanometers and transmit less than 50% of incident light having wavelengths between 600 and 700 nanometers. Thus, these dyes, when combined with dichroic dyes which have absorption maxima between 400 and 600 nanometers, and nematic liquid crystals, are useful to provide electro-optical displays which change from clear to a neutral black colour or vice versa when an electric field is applied to the electro- optical display.

Title: Axial thrust locking clamp
Inventor: BENIK WERNFRIED
IPC: F16B21/16
Filed: 1984-01-26
Abstract: A bolt 15 passing through a building unit is secured by a clamp consisting of blades 1,2 which are bent into a U-shape. Blade 2 is slotted to permit it to enter groove 4 while blade 1 has a hole which receives the bolt end, blade 1 thus acting as an automatically setting stop to prevent radial removal, snapping into position by virtue of the resilience of the blades. The free end of the blade 2 is in the form of a hook 9 arranged such that it limits access to the end of the blade 1 and prevents it from being moved accidentally and thus releasing the clamp. The hook 9 also forms a crosspiece closing the end of the slot in blade 2 and thus reinforcing it. Tongue 21 bears against the end of bolt 15 and, co- operating with arm 1, clamps the device in the axial direction to prevent rattling. The tongue may alternatively extend from the hook 9 (Fig. 16) or be omitted (Fig. 10). <IMAGE>
