Title: Improvements in and relating to the drying of fuel gases
IPC: C10K1/10
Filed: 1926-10-21
Abstract: 285,936. Cooper, C., and Holmes & Co., Ltd., W. C. Oct. 21, 1926. Drying gases.-Fuel gases passing through a main 1 are bye-passed through brush-washers 6, 6a in which they are treated with hygroscopic. liquid; the liquid is cooled and regenerated by circulation through independent circuits connected to the washers. The washers are formed with pairs of communicating compartments between each of which and coolers 16, 19 the liquid is circulated by pumps 13a, 13d. For regeneration, the weak liquid from the washer 6 is directed through a pipe,24 to a tank 25 communicating with a pump 27 which circulates the liquid in part through a pipe 31 and over evaporators 32 back to the tank and in part into a tank 30 from which the liquid flows through a pipe 36 to the washer 6<a>, the liquid space of which communicates through a pipe with the liquid space of the washer 6. Specifications 248,841 and 266,825 are referred to.

Title: Electric welding machines
IPC: B23K11/06
Filed: 1923-10-22
Abstract: 227,543. Sjobring, N. P., and Swanson, M. Oct. 22, 1923. Welding. - An electric welding machine has two welding-rollers mounted on electric conducting-means with their axes parallel and on one side of the rollers means to adjust them towards or away from one another and on the other side of the rollers adjustable means to hold them in the adjusted position. The rollers 12, between which tubing 13 to be welded is fed, are adjusted relatively to one another by the hand wheels 14<11> and are held in position by the strut 25 which is adjusted by the hand wheel 31. The rollers are adjusted vertically by turning the spindle 15 by grasping the flattened portion 20 and the spindle is held in position by the nut 24. Each of the rollers is electrically connected to its support 11 by a number of plungers 36 which provide a short electric path of low resistance. Alternatively an annular flange on each roller rides in a bath of mercury or other liquid conductor in the corresponding support. The rollers are provided with a conducting-flange 39 and a non-conducting flange 41 chosen to conform with the size of the tubing to be welded, and the tubing is fed so that the seam lies between the conducting flanges where the welding current is localized. The pressure of the rollers on the remainder of the periphery of the tubing prevents distortion. The non-ocnducting flanges have a greater diameter than the conducting flanges, thus preventing contact between the latter and consequent shortcircuiting. The rollers are cooled by water &c. in the trough 33, which is filled through the pipe 33<1> and discharged through the overflow pipe 34. The peripheral grooves 13<1> of the rollers are cleaned by the resilient scrapers 43.

Abstract: 1342658 Driving open-end spinning frames TOYODA JIDOSHOKKI SEISAKUSHO KK TOYOTO CHUO KENKYUSHO KK and MEIDENSHA KK 19 April 1971 [8 April 1970 (2)] 26398/71 Headings DID and DIN In an open-end spinning frame the rotors 4 are driven directly by the shafts of individual variable speed motors 12. The motors 12 may be connected to a high or low frequency power source to give a high normal running speed or a low running speed for piecing up. The low frequency is increasable to accelerate the rotor to normal running speed after piecing up. The power sources may be motor driven generators, Figs. 6 and 7 or static solid state invertors Fig. 8. The feed rollers 1A, draw off rollers 5A and take up rollers 8 may be driven by motors and gearing individual to each spinning unit fed by the two power suppliers, Figs. 6 and 8, also Figs. 3 and 5 (not shown) or may be driven by motor and gearing common to the whole frame, Fig. 7, or to groups of spinning units, Fig. 9 (not shown) in which case clutches are arranged to operate in synchronysm with the switching between power supplies. The opening roller 3 of each unit may be driven at constant speed and is therefore independent of the switching of power supplies to the other parts. Braking of the rotor 4 and opening roller 3 may be provided e.g. by a D.C. supply DE Fig. 3 (not shown) which produces dynamic braking. During piecing up on inititally starting the machine the frequency of the normal running power source is reduced to slow all units on the frame.

A tube for detecting the presence of hydrogen in a gas sample contains a first material 1 to absorb water vapour, a catalyst 2 to oxidize hydrogen at normal temperatures, and a third material 3 to indicate the presence of water vapour caused by oxidation of hydrogen. The first material is in the form of a molecular sieve and preferably comprises hopcalite or another catalyst which oxidizes any carbon monoxide present and absorbs water. As a catalyst for oxidation of hydrogen finely divided metallic deposits of platinum, palladium, or nickel on a carrier of silica gel may be employed. The third material comprises a mixture of selenium dioxide and sulphuric acid monohydrate on a ceramic carrier e.g. sinteredaluminate silicate, the reagent being activated by vapors of petroleum spirit or pentane.

Planing.-Relates to friction clutches, particularly applicable to the feed-shafts of machine tools provided with reversing-mechanism, such as that associated with the table of a planing-machine, and consists in a construction whereby a driven shaft is partially revclved each time the rotation of the driving-member is reversed. A driving- drum d, loosely bearing on the driven shaft a, is rotated with periodic reversals by a spur, bevel, spiral, or other gear-wheel e. Sectors h, h<1> constituting oppositely-acting friction ratchets, are freely mounted on a pin g eccentric to the shaft a. and are normally held in contact with the drum d by springs k anchored to pins j on a disc f fast with the shaft a, a stop m preventing excessive movement of the parts h, h<1> against their springs.

Title: Improvements in and relating to the letting-off of warps in looms for weaving
IPC: D03D49/06
Filed: 1921-10-13
Abstract: 194,343. Versavel, F., Versavel, G., Versavel, R., and Versavel, R. Oct. 13, 1921. Letting-off warps.-Automatic and regular unwinding of warp threads is obtained by carrying a warp-beam on a shaft z mounted in pivoted levers d, which are secured at each side of the loom to a shaft b. The whole weight of the beam acts upon the threads to keep them tensioned, the beam being free to receive a limited up-anddown movement as the leaves open to form the shed. The beam is rotatively connected at one end to the shaft z, and a gear y thereon meshes with a worm x on the shaft l, which is journaled in a piece k secured to the lever d. A ratchet fly-wheel n on the shaft l is rotated by pawls s<1>, s<2> on journals q, q<1>, which are mounted upon a piece p free to turn to the shaft l. In operation, a reciprocating rod h actuates a pusher-rod j the nose v of which contacts with the journal q and moves said journal and the pawls, thereby winding off the warp threads. Should insufficient thread be wound off, the levers d will rise and bring the journal q closer to the nose v, thereby causing the journal to be moved to a greater extent by the nose. The reverse effect is obtained if too great a length of thread is wound off. A brake-pulley 15 on the shaft l prevents the ratchet wheel n from racing when the nose pushes the journal. Weights adjustable along levers connected by rods 13 to the levers d serve to adjust the tension on the warp threads. In order to accommodate warp beams of different lengths, the shaft z is slidable in the lever d and through the gear y, to which it is keyed by means of a set-screw 35. A socket 36 in the end of the shaft z receives the journal of the beam, and a chamber 39 in a head 37, which is secured to the shaft z by a screw 38, engages a flange of a bipartite collar fixed to the end of the beam, and thereby causes the beam and the shaft to rotate together. Similar means for carrying the beam are provided at the other side of the loom.
