Patent GB-2107828-A (GB)
Title: Slide valve
Inventor: HARRIS GEORGE JAMES
IPC: F16K3/02
Filed: 1981-10-16
Abstract: The figure shows the bottom portion of a one piece valve body 1 in which there slides a slide plate 7 shown edge on. A sealing ring 4 is set into one face 2 of the valve body and provides a shoulder 6 against which the slide 7 moves. The flow passage 12 through the valve body has the valve nominal diameter at the face 3 from which the passage flares at 15 to an enlarged cylindrical portion 13 receiving the sealing ring 4 which has a groove 8 into which a proud O-ring seal 9 is pressed. Sealing pressure against the O-ring is generated by a lug 10 with a chamfered face 16 which urges the slide 7 towards the sealing ring 4 when the slide is closed. The valve is therefore sealed for either direction of flow but is preferably used with flow from the face 2 to the face 3 to avoid wear on the seal 9 by the flowing material. The aperture through the ring 4 has the full flow cross section of the valve. The lug 10, as viewed in the flow direction, is profiled so as to merge smoothly into the flared portion 15 and reduce the tendency to catch particulate material. <IMAGE>

Title: Analytical device
IPC: G01N33/52
Filed: 1981-12-11
Abstract: A unitary analytical device has a support structure (10) for manual manipulation, the structure defining a self-filling metering channel (16), and laminate structure (40) including a reagent layer (44), and a filter layer (42) on one side of the reagent layer. The self-filling channel (16), of capillary dimension, accurately meters and positions a minute quantity of liquid to be analyzed adjacent the reagent layer (44) and the filter layer (42) allows a portion only of the liquid to flow into fluid contact with the reagent material in the reagent layer for reaction therewith. The analytical device, with a single step of merely touching the metering channel inlet to a drop of the liquid, automatically meters a precision quantity of the liquid and distributes that quantity in a reaction region immediately adjacent the reagent material for reaction therewith. <IMAGE>

Title: Shut-off valve for filter
IPC: B01D35/153
Filed: 1982-03-19
Abstract: The valve includes a housing (31), and a spool (32). The housing includes a tapered internal seating face (15). The spool has a correspondingly tapered external face (22) provided with a recess (23) and a sealing O-ring (24). The spool also includes a portion (18) slidable in the portion (13) of the housing, and a larger-diameter portion (19) slidable in the portion (14) of the housing. The portion (19) includes a recess (20) and a sealing O-ring (21). A spring (34) urges the spool in the direction to cause engagement between the two tapered sealing faces and thus to close the valve. The spool is moved in the opposite direction to open the valve when a filter element is fitted in the check valve. The design of the valve is also such that liquid pressure forces in the valve tend to move the spool in the direction to close the valve. <IMAGE>

Patent GB-2098875-A (GB)
Title: Heat exchange method and apparatus
IPC: B01D5/00
Filed: 1982-05-19
Abstract: A gas stream including the vapor of a solvent is passed through conduit (28) into a reflux heat exchange (40) so as to effect condensation of substantially all the solvent vapor. Cryogenic liquid is introduced through line (70) into condensate of the solvent vapor collecting in bottom section (42) of the condenser to cool the condensate and to stir or agitate it (such agitation preventing local freezing). Chilled solvent condensate is withdrawn from the bottom section (42) and is returned to overhead section (43) of the heat exchanger (40) via a conduit (66) and thus serves as reflux. A further portion of the chilled solvent may be returned to the condensate so as to augment the stirring or agitation of the liquid. Condensate may be withdrawn through the conduit (50) and passed to storage. 
<??>The gas stream may typically be passed first through a water-cooled heat exchanger (13) and then through a heat exchanger (23), cooled by uncondensed gas from the reflux heat exchanger (40), before entering the heat exchanger (40) so as to condense some of the solvent vapor it contains upstream of the heat exchanger (40).

Title: Distributing liquid flow to a plurality of actuators
Inventor: RAJALA RAUNO
IPC: F15B11/22
Filed: 1982-07-14
Abstract: A method of and a hydraulic circuit for distributing a liquid flow (Q) produced by a pump (2) uniformly to a plurality of hydraulic actuating means (9). The liquid flow from the pump is divided by means of a rotating multiblock distributor (4) into partial flows (Q1) which are each conducted to respective actuating means. Between each block (5) of the distributor and the associated actuating means is mounted a pressure control valve (7) by means of which the pressure (p1) of the partial flows (Q1) are adjusted to the same value which is higher than the working pressure (p2) of any actuating means (9) in order to maintain the pressure difference (ps-p1) constant over the individual blocks of the distributor irrespective of any variations in the working pressures of the actuating means. <IMAGE>

Patent GB-2129581-A (GB)
Title: Central heating systems
Inventor: WARING BARRINGTON JAMES
IPC: G05D23/19
Filed: 1983-10-13
Abstract: A central heating system includes a water heater (1) having a primary thermostat (30) which normally operates to maintain the heated water at a working temperature. The system also includes radiators (24) in heating circuits (17 to 22) for heating associated zones (4 to 9), and a calorifier (2) in another heating circuit (23) for heating water in a tank (3). The flow of water in each heating circuit is controlled by an associated valve (25) which (in the absence of an over- ride signal) can open only when an associated time clock (10 to 13) permits it and is then under the control of an associated thermostat (26, 27). When all the valves are closed the primary thermostat ceases to maintain the water in the heater at its working temperature, thereby enabling heat energy to be saved. The circulating pump (16) is also turned off. The temperature of the water in the heater may be maintained above ambient temperature to reduce delay in returning to normal operation. <IMAGE>

Abstract: A boom comprises one, or more than one, box girder (18) whose longitudinal edges are formed by rods (21, 22, 23) designed to take up the major portion of the forces of tension and compression to which the box girder is subject. The rods (21, 22, 23) are connected with metal plates (25, 26, 27) which are reinforced by metal strips or bands (27) only for taking up forces of compression, the rods being sufficiently thin that they form bulges under loads for which the boom is designed. As shown the cross-section of the boom is an equilateral triangle, though it may be a square, rectangle or trapezium. <IMAGE>

Title: Method for detecting faults in internal combustion engines incorporating turbochargers
Inventor: REES STEPHEN JOHN
IPC: G01M15/04
Filed: 1983-10-25
Abstract: Faults in an internal combustion engine incorporating a turbocharger are detected by monitoring the rotational speed of the turbine of the turbocharger, without intruding upon the internal workings of the engine. Output signals representative of the turbine speed are converted to a voltage waveform indicative of average rotational speed. Alternating components of the waveform are filtered off and analysed to indicate the fluctuations induced by each cylinder exhaust gas pulse. <IMAGE>
