IPC: B23K9/02
Filed: 1966-05-13
Abstract: 1,108,213. Welding by fusion. GERMANIA, CHEMIEANLAGENUND APPARATEBAU, KARL-MARX-STADT, VEB. 13 May, 1966, No. 21361/66. Heading B3R. In a machine for welding cylindrical components end-to-end, a welding head 19 is mounted on an arm of a two-armed frame 3 movable axially of the components to insert the welding head 19 in the components, the other arm being located externally of the components and both arms carrying clamping means. The frame 3 is pivotable by an hydraulic ram 8 about a transverse bearing 2 on a carriage 1 motor driven along rails. The components supported on rollers 20 are held by hydraulic clamps 14, 17 on the external arm which co-operate respectively with a screw clamp 15 and a pivoted abutment 18 on the internal arm. A thrust plate 13 carried by hydraulic rams 12 on a mounting 10 fixable in selected bores 11 of a group spaced along the frame 3 serves to force the components together. Tack welds are made adjacent the clamps, the components are released, rotated, re-clamped, tack-welded and so on until the whole periphery has been tacked. The clamps are then released, the welding head 19 is aligned with the joint and the components are rotated and continuously welded by the head 19. In a modification the clamping means 14, 15, 16, 17 are replaced by a pair of rollers mounted on each arm. At least one pair is driven and one pair is mounted on hydraulic rams. The rollers of each pair are mounted with axes at an angle so that the rollers when rotated press the components together and rotate them at the same time. The welding head is mounted between the rollers on the internal arm and forms a continuous internal seam weld, the tack welding being dispensed with.

Title: Improvements in or relating to compressor plants of variable delivery of pressure fluid
IPC: F04C28/06
Filed: 1939-07-22
Abstract: 531,444. Fluid-pressure servomotors. SCHWEIZERISCHE LOKOMOTIV-UND MASCHINENFABRIK. July 22, 1939, No. 21365. Convention date, July 25, 1938. [Class 135] A control device for a rotary fluid compressor device comprising a rotor 1, suction pipe 2, and pressure pipe 3 is adapted to cut off the driving- motor when the pressure in pipe 3 reaches a given maximum value and to bring in the driving-motor automatically when the pressure drops to a certain value. The pressure pipe 3 is fitted with a non-return valve 9 and is connected via a pipe 14 to a cylinder 14a containing a piston 12 loaded by a weight 10. At a given pressure the piston 12 rises to the dotted line position, and the fluid passes through a pipe 17 and acts upon a piston 13 loaded with a weight 11 of less mass than 10, so that the piston 13 rises to the position shown by dotted lines and by linkage 18 acts upon a mercury switch 19 to de-energize a solenoid 22 and open a switch 25 to stop the driving-motor. At the same time the pressure fluid passes via pipes 17, 17a, 15 to an accumulator 16 and thence to the cylinder 5c so as to depress a plunger 5 and an associated valve 4 against the action of a spring 6 and cut off the compressor 1 from the suction conduit. At the same time a valve 7 is opened to connect the pressure side to atmosphere or to the suction conduit. As the pressure drops the fluid leaves the cylinder 5 and passes finally out of pipe 15d until the piston 13 drops to cut off this flow and energize the solenoid 22 to throw-in the motor. The valve 4 meanwhile returns to its open position under the action of spring 6. The pipe 15 may be fitted with a narrow gauged orifice to retard the closing of the valve 4. The retarded opening of the valve 4 may be effected by an electric time lag relay, or by a plunger oil baffle connected to the plunger 5.

In a thermostatically-controlled gas valve having a diaphragm or piston loaded to close the valve and its opposite sides in communication through a restriction, one side being exposed to the gas supply for opening the valve and the other connected to a low-pressure zone, e.g. atmosphere or the outlet of the gas valve, through a thermostatically-operated control valve, the latter is operated through a lostmotion device adjustable to actuate the gas valve at a predetermined temperature. A spring-loaded thermal bellows 34 connected to a feeler 33 has a rod 40 engaging one limb 41 of a forked lever pivoted at 42, the other limb 43 being opposite a nose 75 of a lever 73 having another nose 77 opposite a head 69 of a diaphragm valve 84 loaded by spring 71 to open and control the outlet 22 from one side of the piston to the low-pressure zone via pipe 30. The lever is pivoted on another lever 72 hinged at 42 and pulled on to an abutment 81 on a rod 80 by a spring 82. The amount of lost motion taken up before the nose 77 actuates the control valve is adjusted by a cam 60 acting through a blade 83 and the rod 80. The limb 43 also actuates an indicator pointer 55 through a link 45, lever 46 and rack 52. In another embodiment, the lost motion between the bellows and a piston control valve is adjusted by a wedge between the two parts. The limbs 41, 43 are bimetallic and the pointer is operated via an ambient temperature compensating means.
