Title: Process for the decomposition of coking gases and similar gas mixtures
IPC: F25J5/00
Filed: 1930-08-08
Abstract: 360,487. Separating gases by liquefaction. GES. FœR LINDE'S EIS, MASCHINEN AKT.-GES.,Hollriegelskreuth, near Munich, Germany. Aug. 8, 1930, No. 23849. Convention , date, Aug. 9, 1929. [Class 8 (ii).] Coke-oven or illuminating gas or the like is separated into its constituents by passing the,gas, without removal of its solidifiable constituents under a pressure of several atmospheres through reversible cold recuperators 2, 3 through which the fresh gas and the cold separation products pass alternately, and the gas thus cooled enters countercurrent coolers 4, 7 in which it is decomposed. The fresh gas cooled in regenerator 2‹ to 120‹ abs. cools further in the separator 5 and deposits methane which is expanded through the valve 6 and returned through the exchanger 4 and the regenerator 3. The gas from the separator 5 is further cooled in a separator 8, the residual hydrogen &c. being expanded in an engine 10 and'returning through the exchangers 7, 4 to the regenerator 3. The carbon monoxide condensed in the separator 8 is expanded and returned separately through the exchangers 7, 4 to the point 15. From this point it may be led through a separate pipe in the regenerator, or the regenerator may be subdivided or three regenerators may be employed through each of which passes fresh gas, methane, &c. and carbon monoxide in succession. Alternatively, the methane products are recirculated-through the regenerators by a pump 17 and cooled in a counter-current apparatus 18 by the carbon monoxide. The process may be. applied to illuminating gas, which may be cooled in counter-current apparatus to - 50‹ C. for removal of benzol before passing, through the regenerators.

Abstract: 774,065. Sawing; grinding. OREGON SAW CHAIN CORPORATION. Aug. 19, 1955 [Feb. 10, 1955], No. 24000/55. Classes 60 and 145  The side-cutting teeth 36 and raker teeth 46 of a saw chain are sharpened by removing material in one or more passes from the top surface of the teeth by means of a grinding wheel 82 while the chain is moved in a circular path, e.g., round the nose of a saw bar 72. Each tooth is arranged rearwardly of the axial point of its link so that the tooth is presented to the grinding wheel at an angle giving a downward rake from the front cutting edge. The periphery of the grinding wheel may have bevelled edge portions 86 or be convex so that the raker teeth are of less height than the side cutting teeth, or be straight-across, in which case the two types of teeth have the same height. A  further control of the relative heights of the teeth may, however, be obtained by arranging the side-cutter teeth and raker teeth at differing distances from the midpoint of their links, e.g., if the raker teeth are at a greater such distance than the side cutting teeth, they will be ground to a lower height. The teeth may be made of hard material or may have a layer of tungsten carbide or other such hard matrial applied, in the case of the teeth 36, to the outer side and front faces that form the cutting edge.

Abstract: 1,273,541. Erecting mobile jib cranes. W. F. VONCK. 20 May, 1969 [21 May, 1968], No. 24139/68. Heading B8B. A jib crane, Figs. 1, 3, comprises a chassis 1 with spaced super-structure support areas 3, 4, 4 constituting the turntable for the crane. In the stored position of the telescopic jib 6, 7, 8, 9, it is supported by both the areas 3, 4 with its lower end adjacent the area 3. To erect the crane the left-hand end 7A of section 7 is separated from the area 3 (which may be a counterweight) and the sections 7, 8, 9 slid through 6 to an intermediate cantilevered position, Fig. 2 (not shown), by operating telescoping winch 13. Latches (not shown) are then automatically released enabling the telescoped sections 8, 9 to be extended, after the jib is inclined to an appropriate angle about pivot 6 using derrick winch 19, by the winch 13, Fig. 3. In a second embodiment, Fig. 6 shows the first stage of erection of a tower crane, jib section 33 having been unfolded from alongside section 32. Derrick winch 42, Fig. 7A, is first operated slightly to raise the upper end 30B of the tower 30, whereafter telescoping winch 38 is operated to pull the tower foot 30A towards the turntable 4, simultaneously paying out cable into the derrick cable. During this movement rollers 45 engage guide rails 46 which guide the tower foot 30A into its operational position where it is latched against further sliding movement. The derrick winch 42 is then operated to draw the tower 30 upright against heavy springs (not shown), (which assist in collapsing the crane), where it is latched or pinned in place. The jib 31 is then turned horizontal by attaching load hook 60, Fig. 11, to the turntable 4 and simultaneously pulling in hoist cable 61 and paying out cable from the derrick winch 42, Fig. 12 (not shown). This embodiment may be used as a derricking jib crane by leaving the jib 30 latched alongside the mast 30, the combination being used as a jib.

Title: Improvements relating to ventilator devices
IPC: B60H1/26
Filed: 1958-07-28
Abstract: 856,715. Ventilators. AUSTER Ltd., and SMALL, W. W. June 5, 1959 [July 28, 1958], No. 24202/58. Class 137. A ventilator device comprises a tubular casing 1 having apertures 5, 6 which is fitted in the wall of a space to be ventilated, e.g. a motor vehicle, inlet and outlet apertures 15, a Venturi tube 16, and a rotatable cylinder 17 of rigid plastics material having a handle 26 which is moved in order to open or close the apertures 5, 6. The cylinder 17 is mounted between end members 2, 2 of the casing 1 by means of felt rings fitted into socket portions of the members 2, Fig. 5 (not shown), and is held frictionally in any set angular position. A valve 25 allows air to be drawn from the vehicle interior when the cylinder 17 is closed. In operation, the movement of the vehicle causes a high velocity air stream to pass through the Venturi 16 thereby causing a suction of air through the apertures 5, 6 and creating currents both from exterior to interior and in the reverse direction. In a modification, a single long outer casing may contain more than one inner rotatable cylinder lying end to end and being independently operable. When applied to a building the movement of air through the Venturi 16 may be caused by a fan. In a vehicle capable of travel in either direction, e.g. a railcar, the device may have a Venturi at each end, the stream of air inside the cylinder being deflected by baffles to reach one or more outlets. The device may also be fitted to the front of a vehicle, a baffle being provided at the outlet end.

Title: Improvements relating to methods of and machines for dressing fish
IPC: A22C25/00
Filed: 1956-08-10
Abstract: 842,007. Fish, cutting off fillets. BAADER, R. G. T. Aug. 10, 1956, No. 24611/56. Class 28(2). In cutting fillets from the bones of a fish by various pairs of closely spaced disc cutters, which accomodate the spines of the bone between them, the spacing of each pair is determined by a feeler while the position at which each pair begins and ends the cut (to allow for the position of the belly) is determined by another feeler. In Fig. 4 a beheaded fish on a spike 5 has its belly slit open by a disc cutter 1 as in Specification 840,969 and in moving to the left has its guts removed by the pointed part, Thereafter the first cuts are made from the end of the belly to the tail and half way up only, by the spaced disc knives 140. Second, the flesh is cut off from the belly ribs by a pair of inclined knives 141. The final cut is made all along the back and down to the previous cuts by a pair of upper disc knives V, thereby severing the fillets. The fish is slid over the various saddle shaped guides 7 by a pair of moving endless belts Fig. 5 (not shown) which grip each side of the fish. The back of the fish passes in succession under the pivoted feelers 1, 2, 3 and 4 which thereby in accordance with the thickness and size of the fish actuate mechanisms to space apart each pair of disc cutters 140 and 141 to cut close along the spines and ribs of the bone and also to determine the position along the length of the fish at which the cutters begin and finish the cutting. The feeler 1 moves a sleeve 8 up and down to control the movement of a rack 30 which is actuated by a friction cam 11 whereby a bar 50 and another lever pivoted at 32 acts to space apart the disc cutters 140. After a certain time a lug 13 on cam 11 allows the feeler 2 to release a latch 15 whereby friction cam 18 revolves and through a connecting rod pivots a shield 6 to uncover the top of the cutting edges of the discs 140 whereby they can make the first cuts from the belly end to tail. The knives 141 are similarly adjustably spaced apart .by the feeler 3 and a cam 26 which is released to rotate by a latch 84 actuated by a lever 66 and a lug 12 on the timing coupling 10 of the first cam 11. The feeler 3 and cam 26 also act to set the saddle guide in accordance with the size of the fish, i.e. it is lifted up to lift the fish clear of the knives 141 at the tail end of the belly cavity. The feeler 4 determines the timing of this lift, i.e. when the fish passes the feeler 4 it falls down thus actuating a mechanism 21 and cam wheel 22 to move the guide 7 up to raise the fish clear as above. Fig. 6 (not shown) shows details of the actual mechanism. All the feelers are weighted so that the mechanism resets itself for the next fish.
