Title: Unidirectional friction clutches
Inventor: OLIVER EDWARD WESLEY
IPC: F16D41/069
Filed: 1959-06-16
Abstract: 884,799. Ratchet clutches. WELLINGTON TUBE WORKS Ltd. May 18, 1960 [June 16, 1959], No. 20576/59. Class 80 (2). [Also in Group XXVIII] A ratchet clutch comprises a single loop of wire c, Figs. 1, 2, having its two ends d fast in one clutch member a and its loop arranged to engage frictionally with the inside of an axial bore in a second clutch member b. The clutch is particularly for use in tube wrapping machines, wherein a helically coiled protective wrapping is applied to the outsides of metal pipes connected end-to-end, the connection between each pair of pipes being broken on completion of the wrapping process. In one form connecting two shafts a, b, Fig. 4, two wire loops c have their ends d fast in coupling members e<SP>1</SP>, e screwed together and locked by a screw pin g, the wire loops engaging the insides of the coupled shafts. In another form for use in a tube wrapping machine, wire loops c, Fig. 5, have their ends d carried in coupling members h<SP>1</SP>, h, the coupling member h<SP>1</SP> having a projecting spigot k engaging in a corresponding recess i in the coupling member h. The two wire loops c engage frictionally with the inside of pipes p<SP>1</SP>, p. Each coupling member h<SP>1</SP>, h is fast with a hollow cylindrical extension m carried by axial bars n, transverse plates o therein holding the wire loops in position. After a pipe has passed through the wrapping process, the associated coupling members are separated by imparting a sideways movement to the free end of the pipe p<SP>1</SP>, which movement breaks the wrapping round the coupling members. Later, the coupling members together with their clutches are removed from the pipe ends, for subsequent re-use in other pipes to be fed into the machine. In another form of clutch for use in a tube wrapping machine, a single coupling member h, Fig. 9, is used, provided with a cylindrical extension m carried by axial bars n. Wire loops c engaging the insides of pipes p<SP>1</SP>, p are held in position by two discs q and screws r inserted through the coupling member h. As before, when the wrapping process has been completed, the pipe p<SP>1</SP> is moved sideways to break the connection between the parts. As modifications, the wire loops c may be of elliptical or other shape. Specification 784,756 is referred to.

Title: Method of atomising fusible materials
IPC: B05B7/20
Filed: 1920-07-10
Abstract: 148,776. Marks, E. C. R., (Metallatom Ges.). July 10, 1920. Coating surfaces with glass.-In apparatus for coating surfaces by spraying fusible material such as glass, of the kind in which the material in the form of a ribbon is progressively fused and then sprayed by means of gas pressure, the material to be sprayed is unrolled from a drum and fed through the opening 2, Figs. 3 and 4, and thence by feed-rolls 5, 6, Figs. 1 and 3, to the slot-shaped nozzle 8, where it is fused and sprayed. Oxygen and hydrogen for the fusion of the material are supplied through passages 14, 15, Fig. 2, from whence they pass to grooves 24, 25 in the ring 22, and from thence through ports to the groove 26 in the ring 28, which communicates with passages 10 leading to the orifice 9 surrounding the nozzle 8. Air is supplied through the passages 16, 20, 21 to the groove 29 in the ring 22 from whence part passes to the passage 11 to atomize the material, while another part passes to the turbine 31 which actuates the rollers 6 through worm-gear 33, 36. The body of the apparatus is mounted in a ring 45 which carries the handle 46, and stop-cock 17. The rings 22, 23, 28, 45 are grooved to fit and are clamped together and to the body and nozzle head by means of screw rings 49, 12. The ring 22 carries more than one series of passages for the admission of combustion and atomizing gases so that by varying the relative positions of the rings 22, 45 the nozzle takes a different angular position in relation to the handle 46. The rollers 6 are mounted in fixed bearings, while the rollers 5 are mounted in bearings on a rotatable bearing arm 37, and kept pressed against the rollers 6 by means of a spring 39. To adapt the apparatus for strips of varying widths, the nozzle system and leading-in members 2 are changeable and the distance between the rollers 6 may be adjusted by means of forks 41 engaging grooves on the rollers and carried by nuts actuated by right and left-handed screws 42. The corresponding movement of the rollers 5 is effected by means of flanges on the rollers 6 engaging grooves in the rollers 5; these flanges also serve as stops for the edges of the fusible strip.

Title: Improvements relating to the electrical firing of explosive mines
IPC: F42D1/05
Filed: 1918-12-12
Abstract: 141,404. Cruz, J. L. V. da. Dec. 12, 1918. Mines, marine and land.-Consists in a device for automatically firing explosive mines through the magnetic action of a vessel or the like upon a detector of magnetic forces operating in conjunction with electric firing-means, the detector being influenced by the horizontal and vertical components of the magnetic force in such a way that the explosion of the mines occurs only when the vessel or the like is directly above them. The magnetic detector is of the kind described in Specification 117,825, and comprises a pivoted magnet carrying four points C<1> - - C<4> which bear against fixed microphone boxes M<1> - - M<4>. The points C<1>, C<3> are arranged for contact in a vertical plane, and the points C<2>, C<4> for contact in an horizontal plane. Two relays R<1>, R<2> are provided, each having two opposite windings. These are connected, as shown, to the four microphones, and to leads Q<2>, Q<4>. The armature of the relay R' forms part of a switch T' that is normally open, and the armature of the relay R<2> forms part of a switch T<2> that is normally closed. The switches, the group of mines E, and leads Q<1>, Q<3> are interconnected as shown. The effects of the coils in the relays are balanced so that normally the armatures are not attracted. When, however, a vessel approaches, the horizontal component of its magnetic force exerted on the detector causes the pressure on one of the microphones M<2> or M<4> to be increased. This brings the relay R<2> into action, causing the switch T<2> to be opened. When the vertical component of the magnetic force acts on the detector, the relay R<1> likewise operates, closing the switch T<1>. This condition remains until the vessel is vertically over the mines, when the magnetic horizontal component suddenly ceases, and the relay R<2> consequently allows the switch T<2> again to close. Both switches T<1>, T<2> being then closed, the mines are exploded by the current which then passes through them. Instead of the return wires Q<3>, Q<4>, an earth return may be used. The connecting-leads are enclosed in a cable which is connected to the mines in each group and to a junction-box containing the magnetic detector and relays controlling the group.

Title: Improvements in the process of producing ammonium nitrate
IPC: C01C1/18
Filed: 1924-09-06
Abstract: 221,514. Synthetic Ammonia & Nitrates, Ltd., (Assignees of Greathouse, L. H.). Sept. 6, 1923, [Convention date]. Ammonium nitrate and nitrite. - Nitrogen oxides are absorbed in an aqueous solution of ammonium carbonate or bicarbonate and the resulting solution containing ammonium nitrate and nitrite oxidized wholly to nitrate by means of nitric acid which may be prepared from a portion of the nitrogen oxides by absorption in water. In the plant shown in the Figure, nitrogen oxides produced in a converter 1 preferablv from a mixture of air and synthetic ammonia pass through a condenser 2 to the top of an absorption tower 3 in which they meet water introduced at 3<b>. The unabsorbed gases are conveyed to an oxidizer 4 and then through a series of ammonium bicarbonate absorbers 5, 6, 7 and 8. In the absorbers 5, 6, 7 practically the whole of the nitrogen oxides are absorbed with liberation of carbon dioxide which is re-absorbed in the final tower 8 fed with ammonia at 8<c> and water at 8<b>. The mixed solution of nitrate and nitrite from the tower 6 is finally oxidized wholly to nitrate in the tower 9 by means of nitric acid delivered from the tower 3, the liberated nitrogen oxides being returned to the system through pipes 9<b> or 9<c>. Air may be introduced at 9<d> to facilitate the oxidation. Preferably the absorbing ammonium compound solution is used at a temperature of 0‹ C., and an excess of ammonium compound is always employed to prevent the formation of free nitric acid. Oxidizing chambers similar to the chamber 4 may be placed between the absorbers 5, 6 and 7. The ammonium nitrate solution may be evaporated after it leaves the tower 9 or after concentration by repeated use as a vehicle for the ammonium compound in the towers 5, 6, 7, 8. The Specification as open to inspection under Sect. 91 (3) (a) includes the use of a solution of any ammonium compound for absorption of nitrogen oxides. This subject-matter does not appear in the Specification a.s accepted.

Circular machines.-In machines provided with a striping or patterning attachment, automatic means are provided for bringing the striping attachment into action and also for cutting out the splicing thread without stopping the machine on the completion of a heel or toe and the resumption of continuous work. The clutch controlling the striping attachment is controlled by a shaft C on which is mounted an arm B engaged by a pattern cam A for the production of interrupted stripes. A hand-lever D for manually throwing out the patterning attachment by moving the arm B has a stud K engageable by a catch E to hold it back against the action of a. spring- The catch E is adapted to be released by a lever F, the further end of which has a pawl or tumbler G lying in the path of a lever H on the shaft J which controls the change mechanism from continuous to reciprocating motion and vice versa. When the lever H is moved owing to the change from continuous to reciprocating movement it moves aside the pawl G and does not release the lever from the catch E, but on the return movement the lever D is released and the striping mechanism put into action. The shaft J when turned to effect reciprocating motion is held by a pawl L on the lever H which is disposed in the path of a cam M<1> on the main controlling shaft M so that the shaft J is released from detention to be turned by a spring connected to the lever H. To provide for the cutting out of the splicing thread a pair of scissors P is provided on a tension-carrying pillar Q at a point below the main thread (not shown), the splicing thread O being conducted so that it passes between the blade. The main thread tension pillar A encloses a vertical shaft S having an arm T which engages one of the scissor blades.
