Abstract: 379,217. Moulding biscuits in roller-sheeting machines. VICARS, Ltd., T. & T. and CROSLAND, E. M., Earlestown, Newton-le-Willows, Lancashire. Jan.25, 1932, No. 2191. [Class 87 (ii).] In the manufacture of biscuits, the scrap dough from the cutting-out machines is returned to a separate sheeting-machine in advance of the main sheeting-machine so that the scrap is delivered as a superposed layer on the main sheet. Thus, dough from the shoot 1 is delivered to the cutting-mechanism 9 via the sheeting-machine 3 and gauging rollers 5 .. 8, and the scrap is re-delivered by a conveyer 14 to the separate sheeting-machine 16.

Title: Process for the recovery of heat from hot gases
IPC: B01J19/00
Filed: 1955-01-26
Abstract: 775,600. Cooling gases by direct contact with liquids; heating feedwater; heating steam boilers by hot liquids. PILO, C. W. Jan. 26, 1955 [Jan. 26. 1954], No. 2374/55. Classes 64(1) and 123(2) A non-aqueous liquid, having its boiling point much above 100‹C. and a negligible vapour pressure at its lower working temperature, is used to transfer heat from hot gases to water or another liquid by being brought first into direct contact with the hot gases, which flow in the same or opposite direction, and then into indirect contact with the water or other liquid. The hot gases heat the liquid almost to their own initial temperature, and the liquid gives up most of its absorbed heat to the water or other liquid. The heat transfer liquid may be tetradecane. In the form shown, hot waste gases, e.g. from the coke oven, are cooled in two stages in a directcontact heat exchanger 2, by tetradecane circulated in two closed circuits. The heated tetradecane from stage I is pumped by a pump 7 first to a steam generator 8, then to a feedwater heater 12, and then back to the spray in stage I. If dust has been entrained, part of the liquid can be drawn off at 13a for cleaning. The heated tetradecane from stage II is collected on a tray 4 and passes first to a liquid separator 16 where condensed water is removed, and is pumped by pump 19 through a water heater 21 back to the spray 5 of stage II. Part of the water from the heater 21 flows to the feed water heater 12. Fresh tetradecane may be supplied to the second circuit at 27 and tetradecane entrained by the hot gases in stage I and deposited in stage II is replaced through a duct 28 connecting the two circuits. The heat absorbed from the hot gases in stage II may be used in a heat pump.

Abstract: 878,347. Cross-border mechanisms for looms. EADIE, E. S. Jan. 28, 1958 [March 29 1957], No. 2751/58. Class 142(2) In a loom having a pattern chain for the shedding mechanism and a pattern chain for change boxes the two chains can be clutched together and also declutched. The clutch is engaged to bring the box chain into operation by a connection from the take-up shaft after a predetermined length of cloth has been woven. Disengagement of the clutch is brought about by a bowl on the box chain. The shedding chain drum 1 and box chain drum 2 are mounted on the same shaft 6, engagement of a clutch 9, 10 causing the shaft 6 to drive the drum 2. A spring 14 tends to move the clutch parts together. The take-up shaft 26 drives gearing 27-31 and after a predetermined length of cloth has been woven a bowl 36 engages and lifts a rod 38 whereby a projection 39 raises a notched bar 18 thereby permitting a bell-crank lever 15a, 15b to turn under the action of the spring 14 and a lever 12 connected to the clutch part 10. The lever 18 is connected to a lever 19 which is moved through a bowl on the box chain. Movement of lever 18 causes the lever 15a, 15b to swing in the direction of arrow B and, the lever 12 disengages the clutch. The spring 14 is compressed by movement of the lever 12 and clutch part 10 in readiness for re-engagement of the clutch.

Abstract: 694,814. Bearings. PLESSEY CO., Ltd. Feb. 5, 1952 [Feb. 5, 1951], No. 2787/51. Class 12 (i). The end bearings 1, 2 of a gear pump have adjacent flats 9 which are maintained in pressure contact with one another by resilient means which impart a turning moment to the bearings. The resilient means may comprise two preformed resilient rods 8, Fig. 3, which engage opposed pockets 7 in the bearings 1, 2, and when assembled the rods are subjected to elastic deformation and thus impose a turning moment on each bearing. In a modification, the pockets 18 of bearings 19, 20, Fig. 7, are arranged asymmetrically on one side of the centre line and a straight rod 21 of resilient material is inserted into the pockets. The rod 21 becomes deformed when the bearings are assembled as shown in Fig. 8.

Title: Two phase counter-current batch system for the fractionation of mixtures of electrolytes
IPC: B01D15/08
Filed: 1952-09-11
Abstract: <PICT:0721181/IV (b)/1> In the purification of penicillin by a reflux process (more fully described in Group VI Abridgment), an apparatus comprising an extraction zone Z1, wherein penicillin and other acids are absorbed from solution in a feed solvent as salts in a polar carrier phase, a stripping zone Z3, wherein the acids are liberated by means of a stripping solvent consisting of a stronger acid dissolved in a non-polar solvent miscible with the penicillin feed solvent, and an intermediate reflux zone Z2, is employed.  As described with reference to penicillin an amyl acetate solution of impure penicillin is treated with a carrier phase consisting of quartz, diatomaceous earth, and caustic potash which is then passed in countercurrent to a stripping solvent consisting of an amyl acetate solution of phosphoric acid.  Since the pH rises as the process proceeds, the recovery of substances sensitive to high pH (in particular penicillin) may be ensured by adding an acid weaker than the weakest acid it is desired to recover in sufficient concentration to buffer the pH at the top of the column in the latter stages of fractionation.  Phenyl acetic acid or acetic acid may be employed for this purpose. Specification 599,854 is referred to.

A hydraulic jacking-system for a side-loading fork-lift truck includes a pair of jacks 12, Fig. 1, which extend between the chassis and the axles 2 of the road-wheels 3 on the loading-side of the truck, and a further pair of jacks 17 attached to the chassis on said side and having feet 19 that can be brought into contact with the ground to stabilize the truck when the lifting fork 7 is to carry a heavy load, the two pairs of jacks being independently connectable to a source of hydraulic fluid 25, Fig.3, through associated control valves of conventional kind and hydraulically connected to each other through non-return valves 21, 23 when the jacks 17 are brought into use and when the pressure in working chambers 15 thereof becomes at least equal to that in the corresponding chambers of the jacks 12 so that the jacks are uniformly loaded. Each of the axles 2 is pivotally attached at one end thereof to the chassis, Fig. 2 (not shown), the opposite end being pivotally connected to the piston rod 11 of the corresponding jack 12. The valve 23 has a sense of direction opposite to that of the valve 21 and opens simultaneously with the latter to effect equalization of pressures in the lowermost working chambers 16 of the two pairs of jacks, from which chambers hydraulic fluid is expelled when the jacks are being loaded, these chambers being used to effect retraction of the pistons 13 when required. Alternatively, the pairs of jacks may be replaced by single jacks, the valve 23 and the conduits associated therewith being dispensed with each jack may single acting instead of double acting as shown and more than two jacks may be hydraulically connected in parallel in the manner shown in Fig. 3. It is stated that the jacking system is applicable to progressive jacking of tunnelling supports, a plurality of jacks for said supports being hydraulically connected with one another through non- return valves in the manner described so as to permit the introduction of additional supports without interruption of the supply of hydraulic fluid to the jacks of the existing supports. The invention is not restricted to the use of a hydraulic fluid in the system.

The temperature of air leaving the outlet 17 is maintained constant by a thermostatically operated valve 19 which allows unheated air to pass through a pipe 22 directly to the outlet 17 where it mixes with and modifies the temperature of the heated air.
