Abstract: 581,150. Forging - machines &c. AMERICAN CHAIN & CABLE CO., Inc. Oct. 13, 1943, No. 16812. Convention date, Feb. 10. [Class 83 (iv)] Work-handling devices for metal working machines, in which the work is both traversed and rotated by fluid pressure operated means, are described as applied to a swaging machine having an anvil die 25, Fig. 1, and a movable die 26 carried by a slide 27 reciprocated by a crank shaft 18 belt driven at 28 and fitted with brakes 29, 30, controlled by a treadle-operated rock shaft 33. The work 40 is held in an adaptor 39, Fig. 2, screwed on a rod 38 and provided with a securing-pin 41. A bearing- block 46 is adjustable on the bed 24 to determine the initial position of the work by contact with a stop 51 screwed on the rod. An adjustable stop 52 controls the other side of the block 46 to limit the amount of feed. The rod 38 is universally jointed at 37 to a hollow piston 36 with a perforated end 70 slidably engaging a non-circular rod 69 on which a fluid operated motor 63 is secured. Fluid is supplied to the rotor at 67 and exhausted at 71 by a part leading to the cylinder 35 and return pipe 73. Fluid is supplied by a pump 82, Fig. 4, mounted in a reservoir 19 secured to the frame above the crank shaft. 'Reciprocation of the pump is effected by a block 90 mounted on the top of the slide 27 and engaging a roller 91 on a rod 92 in a guide 74 and having a head 93 that engages the plunger. A spring 94 maintains the roller in contact with the block 90, and a spring 83 effects the return stroke of the plunger which may be regulated by adjusting a rod 86 by a nut 87 to vary the position at which the end 85 engages a shoulder 84 on the plunger. Fluid is delivered to the pipe 67 past a non-return valve 79 at a pressure limited by a safety valve 80. The reservoir 19 also supports valve mechanism 21, which comprises a sliding valve 100, held in the closed position, Fig. 8, by a spring 101 adjustably loaded to determine the pressure on the piston 36. The amount of rotation of the rotor and rod 38 between successive strokes of the press is determined by the stroke allowed to the pump plunger and the feed is determined by the amount of fluid exhausted from the rotor that passes to the piston 36 according to the loading of the valve 100 closing the return pipe 73. A lever 106 set to act on a cross pin 107 to open the valve 100 has its longer arm connected by a wire rope 108, Fig. 1, to an arm on the rock-shaft 33 so that when the brakes are applied to stop the press the valve is opened and a weight 55 returns the rod 38 to its initial position. In modified forms of work holding adaptors the rod 38 is connected to the work through the medium of a coiled spring.

Abstract: 813,439. Tufting machines. CRABTREE & SON Ltd., D., and FELTON, W. April 5, 1957 [June 4, 1956], No. 17129/56. Class 112 [Also in Group IX] In tufting a base material 20, Figs. 6, 10, a loop of binding thread 36 is introduced therethrough, an end of a length of tufting material 47 is inserted through the loop, and the latter is withdrawn and tightened, whereby the length of tufting material is drawn into close contact with the base material and anchored thereto. The loop is formed by a threaded needle 13, and the tufting material, which is in a continuous length, is carried through the loop by a threaded oscillatory looper 46 and is severed by knife blades 53, 54 after the tuft is formed and anchored. In a multi-needle machine different colours of tufting material may be used to produce a striped effect. It is stated that zig-zag and like designs may be obtained by providing a suitable mechanism for shogging the loopers 46. The material 20 is drawn over a horizontal, domed support 10, 11, Fig. 1, formed with a transverse slot 12. A bank of vertical needles 13, disposed below the support and in alignment with the slot, is carried by a needle bar 14 adapted to be reciprocated by means of the co-operation of a roller 16 thereon with a cam 17 fixed to a rotary shaft 18. The loopers 46 are carried by arms 45 fixed to a shaft 44 adapted to be oscillated by a linkage 48, 49, 50 driven by a cam 52 fixed to shaft 18. The material 20 is carried by rollers 19, 25. Roller 19 is braked by a pair of brake shoes 22 in order to tension the material 20. The take-up roller 25 carries a ratchet wheel 27 which co-operates with a pawl 28 driven by a linkage 29, 32, 33 from a cam fixed to shaft 18, the arrangement being thereby such that roller 25 is progressed by one tooth of the ratchet wheel upon each vertical reciprocation of the needles 13. The threads 36 pass from a warp beam 35 to the needles 13 through eyes 43 on the ends of take-up levers 37 fixed to a rotatable shaft 38. An arm 39 also fixed to the latter carries a roller 40 which engages a cam 41 rotated by a shaft 42. The arrangement is such that the levers 37 are operated to tighten the thread loops, for anchoring the tufting material 47, after the loopers 46 have withdrawn from the loops, further movement of the loopers then serving to draw tufting material therefrom to provide projecting lengths of material for the next tufts. A lever 55, which is connected to the movable knife blade 54 and carries a roller 56 engaging a cam on shaft 42, is then rocked to operate blade 54 for severing the tufting material stretched between the loopers 46 and the base material, thus completing a row of tufts and creating fresh free ends of the tufting material.

Abstract: 770,829. Refrigerating; heat pumps. GENERAL ELECTRIC CO. June 14, 1955 [June 14, 1954], No. 17133/55. Class 29 Relates to compression systems having a reversing valve 4 so that, in summer, refrigerant is condensed in an outside coil 8 and evaporated for room cooling in an indoor coil 7 and, in winter, the refrigerant is condensed for room heating in coil 7 and evaporated in coil 8. The temperature difference between the evaporated refrigerant and the air surrounding the evaporator is lower in the latter season than in the former and the object of the invention is to circulate less refrigerant during the room heating state than during the room cooling state. According to the invention during the cooling state liquid refrigerant flows from the bottom of the outside condenser coil 8 through at least two capillary tubes 9, 10 connected' substantially in parallel, but, during the heating state, liquid refrigerant can flow from the indoor condenser 7 through capillary tube 10 only because capillary tube 9 is connected to coil 8 above the liquid level therein. The capillary tubes 9, 10 may be placed in heat exchange with the suction line 3 to the compressor. Valve 4 may be actuated by a thermostat responsive to room temperature.

Title: Improvements in the manufacture and production of paraffin hydrocarbons from carbonmonoxide and hydrogen
IPC: C08G61/04
Filed: 1935-06-14
Abstract: <PICT:0457934/IV/1> In the production of solid paraffin hydrocarbons by thermal conversion of carbon monoxide and hydrogen at pressures of 1--50 atm., the catalyst is continuously passed through the reaction space, freed outside this space at least partly from hydrocarbons deposited on it, and returned, if desired after regeneration. Thus, it may be extracted with a suitable solvent such as middle oil, benzene or pyridine and treated at elevated temperature with hydrogen.  Suitable catalysts are metals of Group 8, e.g. iron or nickel, plus basic substances such as oxides, hydroxides or carbonates of alkali or alkaline earth metals, if desired together with other metals or metal oxides and carriers.  Usually the catalyst traverses the reaction space in 1--3 weeks.  Plate ovens wherein the catalyst is moved over superposed plates by scrapers, or tubular bundle ovens, which may be inclined and include a worm device, can be employed, or the catalyst may be carried by a moving band which can be cooled.  Temperature is preferably 150--300 DEG  C., and the molecular ratio of CO to H2 may be from 1 : 2 to 2 : 1.  The catalyst B is moved by scrapers F over plates D through which a cooling agent is circulated from O, the heat absorbed being utilized at P.  The initial gases enter at M and the products leaving at N are fractionated by cooling.  The catalyst with adherent paraffin wax passes to the chamber H, is extracted in the vessel J, and returned by a worm K and conveyer L.  Specification 364,665 is referred to.
