Abstract: 1350809 Fluid actuated positioning apparatus XYNETICS Inc 20 Dec 1971 [28 Dec 1970] 59044/71 Heading F1D A fluid-pressure e.g. compressed air operated linear stepping motor comprises a rectangular head 10 Fig. 3 having a central vent aperture 94 and slidably mounted on a platen 12 Fig.4; the underface of head 10 having three or more sets of one or more grooves 18, 20 and 22 running parallel to grooves 14 separated by bands 17 extending along the upper adjacent face of the platen 12 Fig. 4 whereby when fluid-pressure is admitted through one or other of valved feed lines 24, 26, 28 to the head grooves 18, 20, 22, e.g., line 26 to three grooves 20, which one phaseshifted in relation to adjacent platen grooves 14 the reaction pressure exerted by fluid-flow through the grooves 20 which are restricted by bands 17 results in linear movement of the head in a direction normal to the groove axis until such time that the selected head grooves 20 register with platen grooves 14 and the feed stream is freely vented to aperture 94. Three further sets of head grooves 50, 52, 54 fed by valved lines 56, 58, 60 are arranged normal to the first three sets of head grooves and run parallel to platen grooves 16 Fig.4a whereby application of fluid-pressure to an appropriate line 56, 58, 60 results in linear movement of the head in a direction normal to the platen grooves 16. Possible arcuate movement of the head is prevented by connecting the feed lines to head grooves 18', 20', 22', 50', 52', 54' vented to the other sides of the aperture 94. The head may be moved by external forces and its position sensed by measuring the changes in pressure in the grooves by gauges 90, Fig. 9.

Patent GB-2040897-A (GB)
Title: Process for the incineration of chlorinated organic materials
IPC: C01B7/07
Filed: 1979-01-25
Abstract: Molecular chlorine level in flue gases from incineration of chlorinated organic materials is reduced by injecting into the incinerator's quench zone an amount of hydrogen which depends on the amount of air fed into the combustion zone, the amount of air being such that there is a 1-40% excess of oxygen. When the wall temperature of the combustion zone is about 800-1500 DEG C, the temperature at which the hydrogen is added to the quench zone is about 450-1000 DEG C. Hydrogen chloride, which is formed from molecular chlorine and hydrocarbon, is more readily water-scrubbed than chlorine, so that less polluting flue gases are obtained.

Title: Acidic Proteinaceous Beverage
IPC: A23L2/66
Filed: 1979-02-28
Abstract: Protein fortification of acidic beverages in significant quantities is achieved without an excessive increase in viscosity and without the necessity of stabilizing additives and emulsifiers. The compositions in ready-to-drink dilute form have a pH of less than about 3.7 and exhibit a stability against protein separation at room and refrigeration temperatures, preferably with concentration of dispersed protein of up to about 7% w/v. The protein fortification is achieved using protein micellar masses obtained from a suitable protein source, such as a plant protein, by extracting with an aqueous food grade salt solution at a temperature of about 15 DEG  to about 35 DEG C, a salt concentration of at least about 0.2 ionic strength and a pH of about 5.5 to about 6.5, and decreasing the ionic strength of the resulting protein solution to a value less than about 0.1 to precipitate and settle the protein micellar mass. The fortified composition may be formulated in dry form with other components of citrus- imitative beverage compositions, for later dispersement in water to form the dilute ready-to-drink composition.

Patent GB-2028466-A (GB)
Title: A Fluid Pressure Relief Valve
IPC: F16K17/12
Filed: 1979-03-21
Abstract: The valve includes a closure member (4), and variable biasing means to bias the closure member into the closed position with the biasing means including a third order lever system formed by a lever (19), a bias weight (11), a movable fulcrum (23) and a valve operating member (21, 22) arranged with the valve operating member engaging the lever between the fulcrum and the bias weight. The biasing means are arranged so that the lever, the bias weight and the fulcrum are movable and their positions are infinitely variable with respect to the valve operating member to provide an infinitely variable pressure at which the relief valve vents fluid. The pressure is varied by rotation of a pinion (23) between a fixed rack (27) and a rack (20) on the lever to cause the fulcrum to move along a slot (28) and the lever and the weight to move relative to the valve operating member. <IMAGE>

Title: Method and apparatus for controlling and monitoring a resistance welding operation
IPC: B23K11/25
Filed: 1979-05-21
Abstract: In a resistance welding operation a fixed constant voltage is maintained between the welding electrodes and sampled to produce a proportional signal which is rectified by a bistable circuit which changes state on each occasion the welding current is initiated. The rectified output is compared with a reference signal, representing the heating effect, and the applied welding current is controlled in accordance with the integrated error. The actual current is sensed at peak passage and the resistance of the weld determined and used to control termination of the welding operation. The actual weld time is compared with upper and lower limits to provide an indication for an operative.

Title: Improvements in or relating to thermal cut-outs
IPC: H01H37/04
Filed: 1979-08-29
Abstract: A thermal cut-out comprises an open ended hollow body 1 made from transparent plastics material, a pair of spring contacts 2,3, a thermoplastic or fusible pellet 4 and a plastics plug 5. The cut-out is assembled with the body 1 in an upright position. The pellet 4 is dropped into the body through the opening and automatically seat itself in recess 9 in the closed end of the body. The contacts are then introduced into the body so that a hooked end portion 7 of the contact 2 engages against the outside of a bent portion 8 of the other contact and the pellet 4 holds these portions in engagement. Thereafter, the plug 5 is snap fitted into the opening between the contacts so as to close the opening and bias the contacts apart. At a predetermined excess temperature, the pellet 4 softens and deforms under the spring action of the contacts to allow them to spring apart and open a protected circuit. This construction of thermal cut-out facilitates manufacture and assembly of such devices. <IMAGE>
Patent GB-2065090-A (GB)
Title: Method for producing zeolites
IPC: C01B39/38
Filed: 1979-09-04
Abstract: As synthesized by previous methods, ZSM-5 or ZSM-11 zeolites are crystallized in the presence of substantial amounts of a nitrogen-containing compound and contain an organic ammonium cation as well as a metal cation such as sodium. To obtain a more active form, the sodium ion must be exchanged out. Such exchange is difficult unless there is calcination of the zeolite to remove the obstructing organic compounds. By making these zeolites in the presence of seeds of the desired zeolite, optionally also with ammonium hydroxide and possibly with an alcohol, as a still further component a product substantially deficient in organic ammonium cation is obtained which can be exchanged directly without any calcination.

Title: Process and apparatus for separating pieces of paper from pieces of plastics
IPC: B07B13/00
Filed: 1980-11-18
Abstract: A process and apparatus for separating pieces of paper from pieces of plastics foil in waste paper pulping are characterized by use of the phenomenon of wet pieces of paper sticking to a rough surface more than pieces of plastics foil. The apparatus accordingly comprises an inclined rough surface such as an endless screening belt (1) which is moved upwardly, the paper moving upwardly with the surface while the foil slides down. In other forms, the rough surface is afforded by the interior surface of an inclined revolving drum. The drum may contain a trough to intercept pieces of paper which are carried upon the surface of the drum and then drop off. Alternatively, the drum may carry an internal helical fin which drives the foil to the upper end of the drum while the paper travels stepwise to the lower end. <IMAGE>
