Title: An improved torque transmission device for use in presses and other workshop machinery
IPC: B30B15/14
Filed: 1956-12-05
Abstract: 804,482. Controlling clutches. EUMUCO AKTIENGESELLSCHAFT FUR MASCHINENBAU. Dec. 5, 1956 [Dec. 5, 1955], No. 37185/56. Class 80 (2). An hydraulically operated friction clutch for driving presses and other machinery is controlled so that the engaging pressure is applied in high and low pressure stages during each cycle of the machine. On actuation of an electromagnetically operated control valve 7 a clutch-driven disc 4 on the machine driving shaft is adapted to be clamped between a flywheel 1 and a pressure plate 3 by low hydraulic pressure supplied from a pump 15 through line 5 to pistons 6. When the pressure from pump 15 reaches its maximum a non-return valve 24 closes and a by-pass valve 16 opens to allow the pump to circulate the fluid pressure. The machine is set in motion by this low pressure engagement until a cam 19 on the crank-shaft 18 of the machine depresses a plunger 20 of a pressure intensifier loaded by compressed air on a differential piston 22, 21. The high pressure developed between plunger 20 and piston 21 is applied to the supply line 5 between the non-return valve 24 and pistons 6 so that the loading of the clutch is increased on depression of the plunger 20 by the cam 19 on each cycle of the machine. Further additional pressure may also be obtained to overcome any high resistance encountered by supplying compressed air to another piston 23 of the intensifier. A brake 8, 9, 10 may be operated in conjunction with the clutch under control of an electromagnetically operated valve 14 from the pump 15 to release as the clutch is engaged and to engage as the clutch is released.

[Also in Group XXXVIII] A method of making a magnetic head for a tape recorder comprises the steps of winding a strip 11 of magnetic material around a mandrel 12 to form a multi-turn helix, severing the wound helix in a direction parallel to the axis thereof to divide it into a number of separate rings having their ends spaced apart laterally, forming a winding 17 on each ring and then pressing the ends of each ring sideways towards each other to close the ring. After winding the helix and mandrel are clamped between jaws 13 and 14 and the helix is cut with a saw or abrasive disc 15. The winding 17 is on a flexible or pre-formed former 19 which may have cheeks. The gap 22 is at an angle to the plane of the ring equal to the helix angle of the original helix and the completed head may be mounted as shown in Fig. 8 so that the gap is transverse to the line of movement of the tape, or may be mounted with the plane of the ring parallel to the movement of the tape. The rings may be made of a high permeability alloy and annealed after forming and cutting, to restore their magnetic properties. The recording gap is provided by copper-plating the rings with a thickness of copper equal to half the width of the required recording gap.

Title: Improvements in or relating to the production of methane gases
Inventor: PERCIVAL GEORGE
IPC: C10K3/02
Filed: 1963-09-23
Abstract: A methane-containing gas is made by providing a mixture of two gases, both containing CH4, oxides of carbon, and H2, one of the gases being such that after methanation it would contain CH4 and CO2, and the other gas having excess H2 and being such that after methanation it would consist principally of CH4 and H2, and effecting methanation to react the carbon oxides with H2 to produce CH4 and steam, the proportions of the two gases being selected so that the final gas contains substantially no oxides of carbon or H2 (i.e. not more than 10% by volume).  The first gas should contain at least 50% by volume CH4 and may be made by catalytic steam reforming paraffinic hydrocarbons and the second gas may be coke oven gas or a gas obtained by gasifying light distillate or heavy oil.  The methanation is carried out catalytically in the range 250 DEG  to 500 DEG  C. and at a pressure up to 100 atmos., preferably 10 to 50 atmos.  In a specific example, desulphurized coke oven gas is mixed with petroleum distillate, and after further purification, the mixture is gasified with steam, over a nickel-alumina catalyst, e.g. of the kind described in Specification 969,637, steam condensed and removed, and the dry gas mixed with the purified coke oven gas for methanation. The final dried gas contained 83.15% by volume CH4.  The methanation catalyst must be cooled, e.g. by recycling cooled product gas or by cooling coils.  The composition of the final gas can be controlled by adjusting the temperatures of the two catalyst beds.  In a modification of the example described above, some or all of the purified coke oven gas is mixed with the mixture of coke oven gas and distillate after the purification of that mixture but before its gasification (see Fig., not shown).

Title: Improvements in tubulous boilers and an improved method of forming vapour heating tube banks
IPC: F22B37/20
Filed: 1960-11-01
Abstract: 886,896. Steam superheaters. BABCOCK & WILCOX, Ltd. Nov. 1, 1960 [Nov. 3, 1959], No. 37485/60. Class 123(3) In a steam boiler having top supporting steelwork 2, a steam and water drum 3 and comprising a gas pass 1 leading upwardly from a furnace chamber, the pass locates lower and upper superheater tube banks A, B which each consist of horizontally spaced vertical platens, each platen consisting of a number of horizontal tube runs connected by return bends, the platens in the upper bank being disposed immediately above corresponding platens in the lower bank. The tube platens of the upper bank B are supported by a series of tubes 4, 4<SP>1</SP> carrying saturated steam from the drum 3 and secured to the steelwork 2 by hangers 2<SP>1</SP>, each pair of tubes 4, 41 passing downwardly between adjacent platens, Fig. 2, and having welded-on brackets 10, Fig. 5, on which the platen tubes rest. The tubes 4, 4<SP>1</SP> connect directly to the upper tubes of the lower bank A. The platens of the lower bank are supported on brackets on tubes 5, 5<SP>1</SP> connected directly to the lower tubes of the upper bank, the support tubes 4, 4<SP>1</SP> and 5, 5<SP>1</SP> being respectively welded together between the banks. In operation steam flows from the drum 3 through the tubes 4, 4<SP>1</SP> to the lower bank A through which it flows downwardly, leaving through bifurcation pieces 11 connecting adjacent platens to a lower header 20. It then flows upwardly through an external connector 21, 23 incorporating an attemperator 22 to a header 24 and enters the upper bank through bifurcating pieces 11<SP>1</SP>. It flows downwardly in the upper bank and then through the support tubes 5, 5<SP>1</SP> and bifurcating pieces 11<SP>11</SP> to an outlet header 26. Thus the steam flow in the banks is in the same direction as the flow of water during the draining of the superheater when starting up the boiler so that water blockages with consequent tube overheating during this period are avoided. The supporting arrangement may also be applied to four vertically spaced superheater banks, Fig. 6, not shown.

Filed: 1958-11-21
Abstract: 906,718. Magnetic compositions. GENERAL ELECTRIC CO. Nov. 21, 1958 [Dec. 16, 1957], No. 37526/58. Class 38 (2). Magnetic particles formed by electrodeposition of iron or iron-cobalt alloy in mercury as disclosed in Specification 815,919 are coated with antimony to prevent spheroidization and magnetic degradation at the temperatures (above 250 C.) necessary for the removal of the mercury. In one method, antimony is alloyed with lead or other mercury-soluble metals and added to the magnetic-particle mercury slurry so that as the lead dissolves it carries the antimony into intimate contact with the magnetic particles. In a second method, the antimony is electro.deposited in mercury and this is mixed with the mercury magneticparticle slurry. In either case the mixture is reacted to 200-300 C. for 10 minutes to form an antimonide coating on the particles. The final magnetic structure may be formed by distilling off the mercury and using an organic binding matrix such as cottonwood oil, tung oil or linseed oil, and this binder is added in a vacuum or an inert atmosphere. Alternatively, a lead or lead-antimony alloy matrix may be provided as disclosed in Specification 906,717. This is added to the slurry before heating, and after heating the material is compressed under 10,000 p.s.i. in a magnetic field of 4000 gauss. The mercury is then removed by distillation at a pressure of 1 mm. of Hg. for 1 hour at 350 C. The remaining material is ground, and compressed under 50,000 p.s.i. in a field of 4000 gauss. Alternatively, the material after distillation may be compressed hot under 3000- 50,000 p.s.i. at 350 C. in a field of 4000 gauss. Reference has been directed by the Comptroller to Specification 815,919.
