Title: Method of and apparatus for welding boilers or other tubular bodies
IPC: B23K9/235
Filed: 1956-07-20
Abstract: 794,001. Welding by fusion. DEUTSCHE EDELSTAHLWERKE AKT. - GES., and RUHRSTAHL AKT.-GES. July 20, 1956 [July 22, 1955], No. 22590/56. Class 83 (4). In arc-welding or autogenously welding the longitudinal or circumferential seams of large tubular members, e.g. boilers, electrical induction heaters are used to progressively heat the seam prior to welding and after welding at the same time as the seam is being welded. The circumferential seam of a boiler 1 is rotated under a welding electrode 4. The seam is preheated to about 300‹ C. by an induction heater 8 and is after heated either to an annealing temperature of 700-750 ‹ C. or a normalizing temperature of 1000-1100‹ C. by an induction heater 9. The heat-treating temperature is maintained by an induction heater 10 and to prevent too rapid cooling the welded joint is covered by a layer 13 of say asbestos cloth. The heaters consists of water-cooled induction loops adjustable to the diameter of the seam. The apparatus may be adjusted for longitudinal welds to be made.

Title: Improvements relating to gas turbine plants
IPC: F02C3/34
Filed: 1947-08-14
Abstract: 638,643. Gas turbine plant. SULZER FRERES SOC. ANON. Aug. 14, 1947, No. 22624. Convention date, Aug. 22, 1946. [Class 110(iii)] In a gas turbine plant of the kind in which the working medium flows round a circuit where it is compressed in at least one circuit compressor and expanded in at least one circuit turbine, from which circuit working medium is extracted and expanded in other turbines, fresh working medium being introduced into the circuit by at least one compressor, at least one independent circuit compressor is driven by at least one independent turbine operated by working medium extracted from the circuit and arranged in series with and before at least one turbine which generates the useful output of the plant. In the plant shown air is compressed in the circuit compressors 1 and 2 with intermediate cooling at 3 and is led through a pipe 4 partly to a heat exchanger 5 and partly to a heat exchanger 6. The preheated air forms one stream at 7 and then divides again at 8. One stream flows through a pipe 9, heat exchanger 10 and pipe 12 to the circuit turbine 13 driving the compressor 1. The circuit turbine exhaust passes back through the heat exchanger 5 and cooler 17 into the compressor 1. The other stream forms combustion air for the fuel burner 21. The hot gases from the combustion chamber 20 pass through the heat exchanger 10 to the independent turbine 29 which drives the independent circuit compressor 2. The exhaust from the turbine 29 is reheated in a chamber 30 and then expanded in the turbine 32 driving the ship's propeller 35. To compensate for the combustion air extracted from the circuit at 8, make-up air is supplied by a compressor 26 and the output of the plant may be controlled by altering the speed of the compressor 26, adjusting its guide vanes or blades or by adjusting a throttling device. The useful output turbine 32 may be in two stages mechanically coupled together with a reheater between them. A further useful output turbine may be provided in the circuit. Reference has been directed by the Comptroller to Specification 619,114.

The compartments have individual heating or cooling jackets 11, 12, 13. In operation, the shaft 3 is rotated at a low speed, preferably 40 r.p.m., the liquids being maintained in a light up and down movement which gives adequate mixing without emulsification.

Title: Improvements in mechanism for delivering printed products in counted batches
IPC: B65H33/18
Filed: 1926-09-15
Abstract: 269,053. Hoe & Co., Ltd., R., (Hoe & Co., Inc., R.). Sept. 15, 1926. Delivery apparatus.-In machines wherein printed products are delivered in batches by an intermittently actuated travelling carrier a cam controlling the actuating mechanism is provided with cam surfaces which can be moved into or out of operative position to vary the frequency of the actuation in order to vary the number of sheets in the batches. Sheets from the printing-press are stripped from a folding-cylinder 3, Fig. 1, by fingers 5, and drop on to a conveyer comprising a pair of endless chains 7, 8, Fig. 3, supporting transverse rods 13 carrying belts 14 on to which the sheets fall. The belts 14 are provided with spaced vertical fingers 9 forming pockets 10. The chains 7, 8 pass around sprockets 11 which are driven intermittently to advance the carrier the length of one pocket after a predetermined number of sheets has been received. The shaft 12 carrying the sprockets 11 is driven by pinions 15, 16 controlled by a ratchet wheel 20 secured on the hub 18 of the pinion 16. The ratchet wheel 20 is engaged by a spring-pressed pawl 28 pivoted on a lever 19 which is loosely pivoted on the hub 8, a rocking movement being imparted to the lever 19 by a connecting-rod 22 pivoted eccentrically on a rotating pinion. The pinion is driven at the same speed as the cylinder 3. The action of the pawl and ratchet of the carrier mechanism is controlled by cam mechanism mounted on a shaft 33 journaled in brackets 31, 32 on the frame 1 and driven by worm and pinion connection with the shaft 25. A cam disc 36 mounted on the shaft 33 is provided with radial slots 37, Fig. 5, forming seating for adjustable blocks 38 with cam faces 39 adapted to co-operate with a roller 42, Fig. 1, on a link 43 which is pivoted to a segmental plate 46 loosely journaled on a stud 17. The lower end of the link 43 is forked to straddle the shaft 33 and is held in position by a collar 45 on the shaft. A torsion spring 48, Fig. 3, on the stud 17 holds the roller 42 in contact with the cam disc 36, and normally holds the segmental member 46 in an elevated position to disengage the pawl 28 from the ratchet wheel 20. The engagement of a cam face 39 with the roller 42 swings the plate 46 from the pawl, allowing the ratchet gear to transmit the rocking movement of the link 19 through the gears 16, 15 to the shaft 12. In the example the cam disc 36 is provided with four slots 37 for cam blocks 38, thereby providing four variations in the number of sheets forming the batches.

A pneumatic tyre has complementary asymmetrical structural means to produce substantially equal drifts of opposite direction when the tyre is moving in a straight line, one drift becoming predominant when the tyre moves round a bend. In one embodiment, the effect of a pair of cross-laid breaker layers with different cord angles is compensated for by providing an asymmetrical tread pattern, e.g. more ribs on one side of the mid-plane than on the other. In another, a carcass ply turn-up or supplementary cord layer in one sidewall is extended beneath a breaker and a reinforcing strip is disposed radially outwardly of the breaker on the opposite side of the tyre midplane. In a third is which the beads include flippers one flipper is extended into the corresponding sidewall and the shoulder on the opposite side of the mid-plane is appropriately reinforced. In a fourth in which one sidewall is stiffened by a supplementary carcass layer, the tread increases in radial depth towards the opposite shoulder.
