Title: Moving belt filter
Inventor: THOMPSON WILLIAM KEITH
IPC: B01D33/04
Filed: 1986-04-22
Abstract: A cloth filter belt 7 is supported by an endless carrier belt 1 where it passes over vacuum box 25. The belt 1 is made in two layers bonded together, the outer layer having relatively low tensile strength (e.g. rubber, polyurethane), and the inner layer having high tensile strength (e.g. steel, nylon, reinforced polymers). Additional reinforcing cards or cloth may be bonded between the layers. The outer layer has drainage grooves or the like leading to holes through the inner layer. Magnetic particles incorporated in the inner layer may cooperate with bar magnets in the vacuum box grid to reduce friction by magnetic repulsion. <IMAGE>

Title: Hydraulically controlled clutch actuating device for automotive vehicles
Inventor: BOEHM PETER
IPC: F02B1/04
Filed: 1987-03-06
Abstract: A hydraulically controlled clutch actuating device, for automotive vehicles, comprises a clutch-pedal operated master cylinder and an auxiliarly spring-loaded master cylinder 1 with a power booster 110 supplying to a slave cylinder actuating a clutch release yoke. In the auxiliary cylinder 1 booster unit, an axially displaceable control piston 3 is coaxially arranged in both a working piston 4, and a pneumatic vacuum power booster which acts upon the working piston 4. The booster comprises a rolling diaphragm 22 and a control valve device controllable by the control piston, with the movement of the diaphragm caused by a pressure difference which acts thereon, being transmitted to the working piston 4 whereby a reaction force proportional to the output pressure acts on the control piston. Upon actuation of the vacuum booster 2, the movements of the working piston 4 and of the control piston 3 occur in opposite directions, with the reaction force being generated by an elastic reaction element 7, concentrally arranged around the control piston 3 between the control piston 3 and the diaphragm 22. <IMAGE>

Title: Painting vehicle bodies
IPC: B05B15/555
Filed: 1987-03-31
Abstract: An automotive vehicle body is painted by painting mechanisms movable along a transfer path near the object. Each of the painting mechanisms has a plurality of paint spray guns displaceable dependent on the surfaces to be painted, the paint spray guns being adjustably located at optimum distances and angles with respect to the surfaces to be painted for applying a uniform paint coat to the object.

Title: Valve
Inventor: KOLENC TERRENCE JAMES
IPC: F16K41/12
Filed: 1987-05-15
Abstract: A diaphragm-type valve uses a multiple annular metal diaphragm (36) welded about its inner periphery to a valve operating stem (34). The diaphragm is sealingly clamped about its outer periphery to the valve body and is also clamped about its inner periphery at a location spaced outwardly of the weld to prevent the weld from being subjected to flexure stresses during valve actuation. The outer periphery of the diaphragm (36 min ) may be welded to the valve body (10 min ) outwardly of the outer clamp. The actuating assembly (20) is arranged to produce non-rotary, reciprocatory movement of the operating stem (34) through a bonnet mounted rotary actuator (116). A stem tip seal (16) comprises a metallic seal ring (152) backed by a PTFE ring (158) and surrounded by a harder plastics ring (160) held captive by a sleeve (166).

Patent GB-2207354-A (GB)
Title: Compositions containing chlorine and/or hypochlorite together with an aliphatic peracid for use in disinfection
Inventor: BALDRY MICHAEL GORDON CHARLES
IPC: C02F1/76
Filed: 1987-07-23
Abstract: Chlorine and hydrogen peroxide react with each other destructively, with the result that a combination of them is less effective as a disinfectant than the chlorine by itself. It would be desirable to locate a peroxygen/chlorine combination that ameliorated or overcame that disadvantage. Advantageously, cooperative disinfection occurs between chlorine and/or hypochlorite with a low molecular weight aliphatic peracid as such as peracetic acid, and the weight ratio of the disinfectants often falls in the range of 1:5 to 1:30. The beneficial effect is apparent even in the presence of substantial residual amounts of hydrogen peroxide remaining by virtue of the method of production of the peracid. Solid surfaces or liquid media, particularly recirculating industrial water can be treated with the combination of disinfectants.
Patent GB-2202359-A (GB)
Title: On-line monitoring and analysis of reactor vessel integrity
Inventor: ACKERSON D SCOTT
IPC: G21C13/08
Filed: 1988-03-16
Abstract: A real time analysis of the integrity of a nuclear reactor vessel 3 is performed by monitoring reactor coolant temperature and pressure and fast neutron fluence, and generating therefrom a visual comparison of the reference nil-ductility transition temperature, RTndt, required for flaw initiation and the actual RTndt through the entire depth of the vessel wall at selected critical locations. When flaw initiation is indicated at any depth, the RTndt required for flaw propagation arrest is also generated and displayed. Thermocouples and resistance temperature detectors 17, RTD's, generate a more accurate measurement of the coolant temperature at the critical locations in the vessel. Under stagnant flow conditions a correlation is applied to the RTD readings to provide the best estimate of coolant temperature at the critical locations. <IMAGE>

Title: Sheet detection apparatus
Inventor: MIZUNO TOSHIAKI
IPC: B41J29/48
Filed: 1989-09-13
Abstract: The presence of a sheet eg in a printer and the type of sheet are detected by comparing the outputs from a pair of optical sensors 4a, 4b with reference values. The sensors may both be reflection types mounted on a carriage 2 and facing high and low reflectivity plates 5a, 5b respectively, so that the positions of the edges of the sheets may be determined. Alternatively, fixed transmission and reflectance sensors may be used to detect sheet pressure only. One or two reflectance sensors mounted on a carriage may also be used to detect the edges of a shoot passing over a plate with alternating high and low reflectivity stages. Traversing of the carriage produces an alternating signal when no sheet is present. …<IMAGE>…

Title: Connector construction for fluid drying tube
Inventor: KERTZMAN JACK
IPC: B01D53/26
Filed: 1990-04-10
Abstract: A method and apparatus for sealing and affixing connectors (26), (27) to membrane tubing (24) reinforced by braided netting material of the braid or of an overlay (31), (33) formed of thermoplastic material (or a combination of both) to produce the mechanical seal between tubing (24) and connectors (26), (27). The seal includes an inner chemically inert tubular insert (28) or (29), which may be formed of stainless steel, ceramic, or glass. The insert (28) or (29) is placed in the end of the drying tube (24). The connector (26) or (27) is fused to tube (24) by applying high temperature and pressure to the area of the tubing over the insert (28) or (29). This causes fusion of either the braiding material itself or fusion of a thermoplastic overlay (31), (33) placed over the end of tubing (24) surrounding insert (28) or (29) and results in a seal which will not leak and which will retain its integrity.
