A resistance butt welding machine comprises clamping means 3, 5, 7, 12, 14, 16 for supporting two workpieces 2, 11 to be welded together, current supply means 9, 18 for engaging and heating the ends of the workpieces, a movable carriage 20 for supporting the clamping means 12, 14, 16 and current supply means 18 for one, 11, of the workpieces, a trimming tool 25 mounted in a housing 24 movably mounted on the carriage, and driving means 32 for actuating the housing to move the trimming tool across the welded joint 37 while the said one workpiece is supported by the clamping means whereby the welding flash can be removed before it has hardened. The clamping means for the workpiece 11 consist of horizontal and vertical clamping jaws 12, 14, 16 which are operated by hydraulic piston-and-cylinder devices and mounted on the carriage 20 which is movable by hydraulic piston-and-cylinder devices 23 on a frame 1 carrying the clamping jaws 3, 5, 7 for the other workpiece 2. Current is supplied to the ends of the workpieces by jaws 9, 18 urged into contact with the workpieces by piston-andcylinder devices 10, 19. The housing 24 for the trimming tool 25 is mounted on rollers 30 on the carriage 20, the workpiece 11 passing through both ends of the housing which is movable longitudinally of the workpiece by hydraulic piston-and-cylinder devices 32. In operation, the workpieces, which may be I-beams for railroad tracks, are positioned in the machine and clamped by the jaws 3, 5, 7 and 12, 14, 16, the jaws 12 and 14 passing through holes 33, 34 in the side plates of the housing 24 and the jaws 16 passing through openings in the top and bottom plates 27, 28 of the housing. The current supply jaws 9, 18 are brought into engagement with the workpiece and the current supplied to the workpiece controlled together with the force applied by the devices 23 acting on the carriage 20 to preheat, fuse and abut the workpieces. While the joint is still red hot, the current supply jaws 9, 18 are retracted and the horizontally opposed jaws 12, 14 are withdrawn from the holes 33, 34 to enable the housing 24 to be advanced by the devices 32 so that the trimming tool 25 removes the flash from the joint while the workpiece 11 is held by the jaws 16 and supported on rollers 35. When the joint has cooled sufficiently, the clamping jaws 3, 5, 7 and 16 are retracted and the workpieces removed. In an alternative embodiment, the sides of the housing 24 are slotted so that the housing can be advanced and the flash removed by the trimming tool without retracting the jaws 12, 14.

Abstract: 1,186,154. Gas turbine plant. WOODWARD GOVERNOR CO. April 16, 1968, No.17961/68. Heading F1G. [Also in Division G3] A fuel regulator comprises a fuel valve 26, an all-speed governor 34 including a selectively adjustable speed setter 52 and means 41 driven in synchronism with a gas turbine engine 12 to vary the energization of a servo for actuating the fuel valve 26 to maintain the gas turbine engine within a narrow steady state speed range while the speed setter 52 remains in a selected position, adjustment of the speed setter causing an element 177 movable in unison with the fuel valve 26 to encounter a hydraulic stop after a predetermined small speed increment to limit further advance of the valve member by the governor to a reduced rate determined by the flow through an orifice 178 or 179. The element 177 is moved during an increase in speed until its edge 191 forms a gap of a few thousandths of an inch with the edge 193 of a port 63b in the servosystem when the pressure drop through the orifice 178 is counterbalanced by a spring 185. During a decrease in speed, the orifice 178 is by-passed by passages 182 and 183 and return flow from the piston 25 for operating the fuel valve is throttled by the orifice 179 and the edge 192 after an initial small change in speed. Isochronous operation during steady state running is provided by an orificed, spring-centred buffer piston 61 which dissipates the pressure differences occurring across a piston 67 on the governor valve in consequence of speed changes. The means 32 ensures a constant pressure drop across the valve 26 which is loaded by the constant pressure supply to the servosystem.

Title: A process for transforming methane into a carburetting agent similar to petroleum
IPC: C10G2/00
Filed: 1926-07-19
Abstract: 255,493. Spindler, H., (Assignee of Goudet, A.). July 18, 1925, [Convention date]. Hydrocarbons.-A hydrocarbon mixture resembling crude petroleum is obtained by subjecting methane, either alone or with the addition of hydrogen-combining gases such as acetylene and carbon monoxide, to a decomposition temperature of 500-950‹ C., cooling the dehydrogenated products, and then passing them over a catalytic material to furnish higher hydrocarbons; the three stages are each conducted under pressure. The apparatus comprises a pressure vessel a containing three tubes b, e, g in series; tube b, which may be surrounded by heat insulation l, is provided with an inlet pipe c and an internal electric heater d; tube e is cooled by an internal water-circulating coil f: and tube g, which contains the catalytic material, is surrounded by a cooling coil i for water &c., and is provided with an exit to the vessel a. The purified methane-containing gases enter tube b under a pressure of 70-200 atmospheres, traverse the electric heater therein, and pass to the tube e, where the products are suddenly cooled to a temperature of 250-350‹ C. If any hydrogen-combining gases are present, these take up the hydrogen liberated by the pyrogenic treatment in the tube b. The cooled products are then directed through the tube g containing the catalytic material, which consists of a mixture of zinc chloride, active carbon obtained by the heat treatment of oleaginous seeds, aluminium powder, magnesium powder, and iron scale previously treated with alkali hydroxide. The vaporous products condense on passing out into the annular space containing the cooling coil i and are discharged through a tap, whilst gases pass out through the outlet k. The resulting liquid is useful as a fuel.

Title: Production of copolymers
Inventor: WEBBER WILLIAM CYRIL
IPC: C07C11/02
Filed: 1962-05-11
Abstract: A methyl pentene is catalytically dimerized or trimerized under conditions such that at least part of the polymer produced is an olefinic hydrocarbon having 12 to 18 carbon atoms and, in a second stage, this olefinic hydrocarbon is copolymerized with a different olefinically unsaturated compound.  Many polymerization catalysts of the Ziegler low molecular weight (defined), Friedel-Crafts, free radical e.g. peroxide and azo, and titanium tetrachloride types are listed.  Specified comonomers are ethylene, propylene, n-butenes and iso-butenes and 4-methyl pentene-1.  Where emulsion copolymerization is used, with for example ammonium persulphate as catalyst, specified comonomers are vinyl acetate, vinyl chloride, vinyl ethyl ether and allyl chloride.  The copolymerization may be effected with the original catalyst under different conditions or with another catalyst added to or replacing the original polymerization catalyst. The copolymerization may also be effected at high pressure with oxygen as catalyst.  In the examples 4-methyl pentene-1 is bulk polymerized to the dimer under nitrogen and under pressure using a catalyst prepared by treating aluminium tri-isobutyl with 4-methylpentene-1 and then copolymerized after adding aluminium chloride in ethyl chloride as an additional catalyst component with as comonomers either isobutene or 4-methyl pentene-1 and after terminating the reaction with methyl alcohol the polymer is precipitated with acetone giving a liquid product.ALSO:As the first stage in the production of a copolymer (see Division C3), 4-methylpentene-1 is dimerized in bulk at 150 DEG  C. under pressure and under nitrogen using an aluminium tri-hexyl catalyst prepared by treating an excess of aluminium tri-isobutyl with 4-methylpentene-1 at 120 DEG  C.

Filed: 1925-07-17
Abstract: 261,449. Blessing, E. F. July 17, 1925. Purifying and refining.-In a puddling process for the production of wrought iron, the refining of the charge is carried out while it is spread over a large area so as to be of shallow depth and then when the refining is practically complete and the iron begins to drop, causing a deepening and lateral reduction of the charge, which is agitated by rocking in both the above stages. The charge is then treated so as to - crowd the ends inwardly to make a more or less rounded form or ball. The process may be carried out in the furnace shown, which forms the subject-matter of Specification 261,812, [Class 51 (ii), Furnaces and kilns for applying &c.]. The first stage of the process is carried out with the charge resting on the part 22 and being agitated by rocking the furnace. The furnace is then rotated so that the charge rests on the parts 23, 24 where it is subjected to further agitation to carry out the second stage and the furnace is then rotated finally so that the charge moves into the portion 25 where the ball of metal is formed. The ball is discharged through the door 19.

Filed: 1922-07-04
Abstract: 182,796. Horton & Son Co., E., (Assignees of Cutler, W. M.). July 8, 1921, [Convention date]. Chucks.-In a disengaging-drive chuck in which the jaws are operated by the rotation of a part relatively to the chuck-body, this rotation is performed by differential gearing. The jaws 5, Fig. 2 (Cancelled), are operated by a scroll 6, which carries an internal gear 7 meshing with pinions 8 secured to pinions 12 of slightly different diameter, which engage an internal gear 13 rigid with the chuck body. The pinions are carried by studs 9 on a ring 10, the relative rotation of the scroll and the body being produced by retarding this ring with respect to the chuck. Retardation is produced by a brake 22 engaging the annular surface 23 of the ring. The Specification as open to inspection under Sect. 91 (3) (a) describes also a means for accelerating the ring to reverse the action of the chuck by means of a differential roller 24, 25, having parts of different diameters which engaged the chuck body and ring respectively and thus rotate the ring faster than the chuck. Friction surfaces may be applied to the roller and its coacting parts, and the roller and brakes may be mounted on a common operating lever 20. This subject-matter does not appear in the Specification as accepted.
