Filed: 1975-12-22
Abstract: 1525508 Hydrodesulphurization of heavy oils SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ BV 22 Dec 1975 [21 Feb 1975] 52343/75 Heading CSE Hydrocarbon oil consisting of either a deasphalted oil or a deasphalted oil in admixture with a distitllate is hydrodesulphurized at a hydrogen partial pressure below 90 bar and a water vapour partial pressure of 0À1-10 bar in the presence of a catalyst which contains nickel and/or cobalt together with molybdenum and/or tungsten supported on a carrier such as alumina or silicaalumina. The water vapour can be provided by the addition of water, steam or a precursor such as an alcohol. The deasphalted oil can be produced by deasphalting a long or short residue, a crude oil or a residue obtained in the distillation of products of the catalytic or thermal cracking of a heavy oil; a suitable feed oil can be prepared by separating a long residue into a distillate and a short residue by distillation at reduced pressure, deasphalting the short residue and mixing the distillate with the deasphalted oil. The desulphurized product can be catalytically or thermally cracked to produce gasoline or kerosine or can be blended with distillate or residual components, such as the asphalt removed from the heavy oil prior to the hydrodesulphurization, to produce a fuel oil.

Title: Device for temperature regulation inside closed spaces, particularly deep-freezers
IPC: F25D29/00
Filed: 1968-11-05
Abstract: 1,223,588. Automatic temperature control systems. FRIAC. Nov. 5, 1968 [Nov.10, 1967], No.52449/68. Heading G3R. An arrangement for regulating the temperature inside an enclosed space wherein materials to be treated are located, e.g. a refrigerator chamber, comprises two thermostatically operated switches connected in parallel and in the operating circuit of a heat or cold source, the operation of a first switch being influenced by the source and the second being located in the space and adjusted, to a cut-in temperature which is higher than the cutin temperature of the first switch the cut-out temperatures being approximately equal. The second switch may be mounted in a location so as to be strongly influenced by the temperature of materials introduced into the space. The first thermostatic switch preferably has a large temperature differential and in the case of a refrigerator is arranged to cut-in at minus 19‹ C. and to cut-out at minus 25‹ C. corresponding temperatures of the second thermostatic switch being minus 15‹ C. and minus 25‹ C. respectively. On the introduction of new products e.g. food, the temperature will be raised above minus 15‹ C. and the second switch will cut-in and remain in until the temperature drops to minus 25‹C. As long as no new products are introduced a compressor supplying the refrigerator will then be controlled by the first switch, this also applying if only small amounts of produce are introduced and to cover heat losses if the refrigerator door is opened. A mechanical connection (not shown) may be provided between the switches to enable simultaneous adjustment of their working ranges. A manually operated push button may also close the second switch this being automatically opened when it reaches its cut-out temperature. The arrangement has the advantage that if one thermostatic switch fails in an open position the refrigerator will still be controlled by the other switch. The arrangement may be applied to the temperature regulation of a furnace.

Abstract: 1281573 Pipe joints GKN SANKEY Ltd 18 Aug 1970 [27 Oct 1969] 52476/69 Heading F2G  A closure unit for fitting to a neck 33 of a container (not shown) to receive pipes for fluid transfer to and from the container, includes an inner tubular member 11, a cup member comprising a tubular sleeve 25 and a separate annular base 26 connected by a bayonet fitting to the sleeve 25, an inner valve member 16 and an outer valve member 30, the valve members being pressed on to their respective seats 15, 28 by compression springs 17, 31. Insert 14 provides both a seat for the inner valve member 16 and carries the outer valve member 30. The inner valve member 16 is attached to valve stem 22 which when depressed passes through a ring 19 of a spider member 18 which supports the spring 17 and prevents the depressed stem 22 from limiting the fluid flow in down pipe 12, which is of smaller diameter than the inner tubular member 11. The spider member 18 has three legs 20 radiating from the ring 19. The base 26 of the cup member is a ring having relatively depressed and raised portions in its circumference. The depressed portions have recesses in their outer surface so that the base 26 can be inserted into the tubular sleeve 25 with these recesses aligned with radially inwardly pointing lugs 34 on the base of the sleeve 25. The base 26 is then pushed further up into the sleeve 25 against the action of spring 31 and then rotated and allowed to fall back to the bottom of the sleeve 25 so that its raised, non- recessed portions contact the upper surfaces of the lug 34 and the base 26 is firmly secured to the sleeve 25. The valve members 16, 30 may be operated by a coupling member fitted to the neck of the container which has portions which abut the valves and depress them against the action of springs 17, 31. Such a closure unit might be fitted to the neck of a gas pressurized beer keg and in this case the down pipe 12 would extend almost to the bottom of the keg.

Title: Indexing mechanisms
IPC: B65G1/07
Filed: 1972-11-17
Abstract: 1396550 Feeding semi-conductor wafers to and from conveyers INTERNATIONAL BUSINESS MACHINES CORP 17 Nov 1972 [30 Nov 1971] 53157/72 Heading B8A Semi-conductor wafers 2 are fed from an input conveyer 16 into a magazine 30 by means of a suction head 26 which is also used to feed the wafers from the magazine 30 to an output conveyer 10. The magazine 30 is detachably mounted on a carriage 70 which is slidably mounted for up-and-down movement on guides 78 under the control of a chain 74. The latter is connected with a continuously running motor 118 by a clutch (134) (Figs. 8 and 9, not shown). The motor 118 provides upward movement, and gravity downward movement, of the carriage 70, but the movement in either of these directions is controlled by the action of a pawl 90 which is successively engageable with a series of projections 86, 87. The pawl 90 is mounted on a carriage 94 laterally slidable on a fixed member 101 (Fig. 7). The projections 86 are laterally offset relative to the projections 87. Operation.-A wafer 4 on the conveyer 16 approaching the magazine 30 is detected by a photo-cell 34. This causes air to be supplied to an inlet 96 (Fig. 5), thereby laterally displacing the carriage 94 against the action of a spring 100. The pawl thus slides laterally from a projection 86 to the next lower projection 87 (or from projection 87 to projection 86 as the case may be). The carriage 70 is thus allowed to index one step downwards by gravity. Arrival of the next wafer causes the pawl 90 to be drawn back along the projection 87 on to the next lower projection 86, and so on. When the magazine 30 is full it can be removed from the carriage 70 or it can be unloaded successively on to the conveyer 10. The carriage 70 is returned to its original uppermost position by the action of the motor 118, the pawl 90 being deflected against a return spring 92.

Fig. 7 shows the suspension unit after the liquid filling, with the cap unscrewed a few turns so that both passages are open. A unit 63 is placed around the suspension unit and gas is supplied to fill the chamber 18, and, via the partition 26, the chamber 9. When both chambers are full, the cap 29 is screwed up to compress the sleeve flanges 41, 42 and isolate the chambers from each other and from the exterior of the unit. The unit is of the self-pumping self-levelling type. Dynamic oscillations of the piston 2 cause a pump plunger 4 to pump liquid from the reservoir 7 into the cylinder 1 to extend the unit until the piston 2 uncovers an aperture 20 in the pump plunger 4. The chambers 16, 18 act as a hydropneumatic spring. Details of the pump valves and of independent damping valves are given (Figs. 2 and 3, not shown).
