Title: An arrangement for controlling the pressure in hydraulic presses
IPC: B23K11/31
Filed: 1956-03-12
Abstract: 826,237. Welding by pressure. VLTAVSKY, M. March 12, 1956 [March 10, 1955], No. 7582/56. Class 83 (4). [Also in Group XXIX] In an hydraulic press, e.g. an electric welding press, comprising a press cylinder and piston 1, a pump 3 for supplying liquid from a reservoir 4 to the cylinder and a distribution valve 2 for allowing the liquid to enter the working space of the cylinder and to return to the reservoir, the working space is connected to the reservoir by a return pipe in which are two or more seriallyconnected spring-pressed piston valves adapted to open when the liquid pressure thereon exceeds a predetermined limit, and at least the valve next to the cylinder has a differential piston with its larger area, in the open position, exposed to the pressure determined by the next valve and is so dimensioned that it is held in the open position when exposed to this pressure. A spot welder has its upper electrode secured to the piston of the press to the cylinder of which liquid is supplied by the pump 3 from the reservoir 4 via the valve 2 which directs liquid above or below the piston and from the cylinder to the reservoir. The return pipe has two spring-loaded differential piston valves 5, 6 in series therein, a solenoid-operated slide-valve 8 and a time delay valve 10 for actuating a switch 11. A spring-loaded differential piston-valve 7 in series with a time-delay valve 12 for operating a switch 13 is arranged in a by-pass circuit from the outlet side of the valve 6 to the reservoir. In operation liquid is supplied to the space above the piston 1 to close the electrodes on to the work and when the pressure builds up to the value A indicated on Fig. 1 the valve 5 opens. The pressure liquid then passes through the valve 6 set at value B and since no back pressure builds up behind the valve 6 the latter maintaining the pressure in front of it at the value B. The differential piston of valve 5 remains lifted at the lower pressure. The liquid flows through valve 8 to valve 10 where it moves the piston to close switch 11 to close the welding current circuit. The solenoid 9 in a circuit closed by switch 11 is energized before the welding current is switched off electronically and closes valve 8 so that when the pressure reaches a value C the valve 7 opens and liquid flows through valve 12 which causes operation of switch 13 to reverse valve 2 and allow the piston 1 to rise and the upper electrode to lift from the work. For flash butt welding the work parts held by electrodes may be moved into contact at an initial high pressure which is subsequently reduced and in this case the valves 6, 8 and 10 are dispensed with.

Abstract: 1,138,287. Polymerizing methyl methacrylate syrups. E. I. DU PONT DE NEMOURS & CO. 23 Feb., 1966 [23 Feb., 1965], No. 7942/66. Heading C3P. A syrup containing 10 to 35% of a methyl methacrylate polymer dissolved in monomeric methyl methacrylate, the polymer having an inherent viscosity of 0À25 to 1À0, is cured in the presence of from 0À05 to 5 mole per cent, based on the number of moles of monomeric methyl methacrylate in the syrup, of a metal salt of a hemi-perester of maleic acid having the formula wherein M is a metal, x is an integer of from 1 up to the valence of the metal and R is a saturated tertiary alkyl radical. When x is less than the valence of the metal, the other valence(s) are satisfied by another anion, e.g. - OH or the anion of the metal compound from which the salt is formed. The polymer is a methyl methacrylate homopolymer or copolymer. M may be Na, K, Li, Ca, Mg, Sr, Ba, Zn, Pb, Mn, Cu, Ni or Co and the salt is formed by adding to the syrup the hemi-ester of maleic acid, e.g. monotertiary butyl peroxymaleate or t-amyl, 1-methylcyclohexyl or p-menthyl peroxymaleate, together with a basic compound of the metal. A cross-linking agent, e.g. ethylene dimethacrylate, propylene dimethacrylate, polyethylene glycol dimethacrylate, divinyl benzene, triallyl cyanurate or diallyl phthalate, may be added to the syrup, which may contain a residual amount of a mercaptan e.g. glycol dimercaptoacetate or isooctyl mercaptoacetate.

Abstract: 273,005. Chitty, H. March 25, 1926. Cores and carcass structures; insulation; coils and conductors.-In a machine in which the slots, are 'bridged by magnetic wedges in such at manner that while there is direct contact between the wedges and laminae there is no closed magnetic circuit through the plane of the laminae around the conductors, the laminae are insulated from each other or from group to group at theperiphery of the core opposite to that in which the slots are located, thus preventing the circulation of eddy currents at this periphery. This may be effected by mounting the laminµ on bolts e, Fig. 1, which are shrouded with insulating material f and by insulating the core endplates from the end laminµ. Alternatively, the laminae may be mounted on and insulated from a key and the machine shaft or on a spider of which the arms are insulated from the laminµ. The type of core to which the invention is applicable, and as described in Specification 12748/15, is shown in Fig. 3. The groups of laminµ c are separated by air spaces b and the slot openings are made wider than the wedges a. Eachgroup of laminae is divided into sections which are so disposed that the seating of the slot openings against the face of the wedge occurs in adjacent sections on opposite sides of the wedge, thereby giving air spaces, indicated by the vertical hatching lines, on alternate sides of the the wedge as it traverses the group of sections.
