Title: Improvements in pipe joints and the like
IPC: F16L33/14
Filed: 1942-09-28
Abstract: 558,574. Band clips. LIPSCOMB, R. Sept. 28, 1912. No. 13568. [Class 44] In a band clip for jointing hose-pipes and like uses and of the kind in which tightening is effected by winding one end of the band on to a bar or spindle, one end of the band is wound several times round the bar, and the clip then passed round the pipe. The other end is then secured to the bar as by being passed through a slot therein and then wound thereon, the other end of the band being simultaneously unwound, the bar being free to have a precessional or planetary movement around the pipe &c. being secured. The invention provides that the winding and unwinding occur at different rates so that tightening is obtained by the differential effect. Fig. 1 shows a bar having the central portion C of greater diameter than the end portions A, B. The bar is provided with a slot D to receive the band ends and with tommy holes E by which the bar may be rotated. Fig. 2 shows a suitable metal tape having a single tongue G at one end and a pair of tongues F, F<1> at the other, the slot between the tongues F, F<1> being at least as wide as the tongue G. In use the ends F, F<1>, which may be united by a crosspiece F<11>, are inserted in slot D and given the necessary number of turns round the ends A, B. The band is then passed twice round the part I to be tightened on the part H and the end G passed through the central part of the slot D and bent down, Fig. 3. The bar is then rotated anticlockwise so that it rolls anticlockwise round the parts H, I, the ends F. F' being unwound from the ends A, B and the end G simultaneously wound on to the part C. As the winding occurs at a greater rate than the unwinding the clip is tightened by the resultant shortening of the effective length of the band. Alternative bands of V-form or of wire, and the use of bands having more than three tongues are described. The parts of the clip may be metallic or non-metallic, a bar of synthetic resin or a casein or cellulose product and a band of catgut, textile or cellulose product being mentioned. A similar differential tightening effect may he obtained by giving the object on which the clip is secured, e.g. a coupling-piece within the ends of two hose-pipes, different diameters to receive the different ends of the clip.

Title: Improvements in or relating to the manufacture of low phosphorus steel
IPC: C21C5/32
Filed: 1957-04-30
Abstract: A process for making steel from phosphoric pig iron by a blowing process comprises eliminating the major portion of the phosphorus in a first refining stage, separating the slag from the metal and tntroducing the latter into a vessel suitable for top blowing without an exterior source of heat, and injecting an oxidizing gas from the top into the bath a dephosphorizing agent being added before or during the second blow.  The first blow may be carried out in a top or bottom blowing converter or rotary furnace until the phosphorus content has reached a value between 0.05 per cent and 0.4 per cent, and the second phase in any vessel suitable for top blowing.  The dephosphorizing agents may be lime, soda, sodium oxide or potassium oxide and may or may not be accompanied by fluxing agents e.g. fluorspar, alumina, or metallic oxides.  A slag of the dephosphorizing reagents with or without fluxing agents may be formed on the surface of a small amount, e.g. one tenth, of the metal to be treated and the remainder of the metal poured on to it.  The first vessel may be of larger capacity than the second and only a portion removed at a time for treatment in the second, fresh raw metal being added to the first vessel to replace that removed and allowed to react with the existing slag, part of which is then removed and an equal quantity of new slag added.  The dephosphorizing agent may be added to the second phase in a granular or powdered state in a gas which may be merely a carrier or may be an oxidizing gas. Carburizing reagents and/or exothermic reagents may be added during either phase of the process.

Title: An improved method of and apparatus for detecting water vapour or either of the gaseous components thereof
IPC: G01N27/04
Filed: 1917-09-28
Abstract: 137,547. Adams, H. E. F. Goold-, Bousfield, W. R., and Todd, G. W. Sept. 28, 1917. Hygrometric apparatus.-Water vapour is detected by passing the gas to be tested over a salt or substance having a definite critical hydration pressure, for example the alkaline chloride or nitrate, which takes up water only if the partial pressure of the water vapour is above the critical hydration pressure of the salt and thereby becomes a conductor, closing an electric circuit. The apparatus shown is suitable for testing a mixture of nitrogen and hydrogen, used for the synthetic production of ammonia, for the presence of oxygen. The gas to be tested is continuously sampled by a by-pass tube a and passes in succession through a drying-tube b, safety tube c, catalyst chamber d in which any oxygen present combines with hydrogen to form water vapour, then through the detecting salt and finally through a sulphuric-acid bubbler q. The dried detecting- salt may be placed between two wire gauze electrodes e, f, Fig. 2, arranged in brass tubes h cemented in a glass tube i. The salt forms part of an electric circuit containing an ammeter or galvanometer g, or a relay n, or both. The relay n may actuate a bell o, or other audible or visible alarm, or means for electro-magnetically cutting off the main supply of gases. A resistance r, equal to that of the salt when moist, may be put in parallel with the detector by a switch s for testing the circuit. A two-way valve p enables gases to be passed through the apparatus at starting without passing through the detector. The detector may be tested by drawing gas free from air or oxygen through a bubbler b' containing 20 per cent sulphuric acid having a definite vapour pressure. An alternative form of detector is shown in Fig. 4, and consists of two fine platinum wires t, t<1> wound round an insulating rod t<2>, on which a thin film of the detecting-salt has been deposited.

Abstract: 1,247,456. Control system for motor. BURROUGHS CORP. 25 March, 1970 [1 April, 1969], No. 14374/70. Heading G4H. The control system for a motor driving a print wheel operates so that the angle moved through by the print wheel between changes in position is a minimum. The position of the print wheel is identified by means of a coded scale which is scanned photo-electrically. The direction control unit 34 has two counters 58 and 66. The required position indicated by keyboard encoder 22 is fed into counter 66. Counter 58 is used to gate clock pulses from oscillator 56 into counter 66 to increment it. Counter 58 holds a count equal in number to half the total number of positions on the print wheel. The output from counter 66 is continually compared with the position coded output from the print wheel. If during the period in which counter 66 is being incremented the output of counter 66 and the new position are the same then a signal is provided which alters the direction via which the print wheel is rotated. In this way the direction of rotation of the print wheel is so selected that the angle moved through by the print wheel is a minimum. The position of the print wheel is continually compared with the output from the keyboard by means of a comparator 128. When agreement is obtained a signal is provided which prevents further rotation. The logic control systems used in this device are JK flip-flops, AND gates and OR gates and inverters.
