Abstract: 1,145,662. Warping-machines. HERGETH K.G. MASCHINENFABRIK U. APPARATEBAU. 1 April, 1966 [3 April, 1965], No. 14476/66. Heading D1M. Short warps for weaving samples are wound consecutively around rollers 5, 6 and crossed by leasing rods 26, 27 to produce crossing points where they are cut to produce a warp length which is a multiple of the loop length around the rollers. The rollers 5,6 comprise a series of transversely moving bands 9 to which the ends of all the threads are attached. Only one bobbin for each colour is provided and the thread passes through an eyed guide 59 which moves on selection to present the appropriate warp to a hook 58 which moves around the rollers 5, 6 to wind the warp. The warp is carried by the bands 9 along the rollers 5, 6 and is crossed by the leasing rods 26, 27 at appropriate times depending on the length desired.

Title: Apparatus for determining the compression strength of the floor and/or roof in a mine working
IPC: E21D15/46
Filed: 1956-05-10
Abstract: 801,605. Testing the floor and roof of mines. BECORIT GRUBENAUSBAU G.m.b.H. May 10, 1956 [May 11, 1955], No. 14595/56. Class 106 (2). An apparatus for determining the pressure resistance of the floor and/or roof in a mine comprises a hydraulic jack 1 associated with a head piece 10 and a base-plate 14 of the types usually fitted to pit props, a pressure fluid pump 3 for actuating the jack until the floor or the roof yields, and a maximum reading pressure gauge 17 for indicating the thrust at that instant. From the test the prop load that can be applied when using a definite size of baseplate or head piece is determined and the thickness of the prop that should be used can then be estimated. The head piece 10 and baseplate 14 are removable so that others differing as regards shape and size may be associated with the jack during the test. There may be a number of extension pieces 7, 7a, 7b, preferably of tubular form. Each extension piece and the press piston are provided at one end with an enlarged coupling sleeve 6 and 9 acting as a socket for the next piece to be secured thereto, a detachable bolt 8 being passed through the sleeves in the vicinity of the joint for the purpose of securing the push-in coupling.

Title: New guanidine derivatives
Inventor: MCKAY ARTHUR FERGUSON
IPC: C06B25/04
Filed: 1952-06-12
Abstract: The invention comprises N-b -nitraminoethyl N1 - aryl - N11 - nitroguanidines of the general formula <FORM:0712461/IV (b)/1> (wherein R represents hydrogen, halogen, an alkyl or alkoxy group containing not more than six carbon atoms, or a hydroxy or acetylamino group), and the manufacture thereof by reacting 1-nitro-2-nitramino-2-imidazoline with the appropriate arylamine. The reaction may be effected by refluxing the two reactants in an aqueous solution (preferably an aqueous alcoholic solution, e.g. 95 per cent ethanol), or by covering the 1-nitro-2-nitramino-2-imidazoline with a liquid arylamine and allowing the mixture to stand.  In examples, the following amines are reacted by one or both methods: aniline, p-anisidine, p- and m-phenetidine, p-and m-chloroaniline, p-bromoaniline, p- and o-toluidine, p-aminophenol, p-sec.-amylaniline and p-aminoacetanilide.

Abstract: 528,992. Sliding-clasp fastenings. WALDES, J., and PUC,V., (trading as WALDES & SPOL). May 18, 1939, No. 14902. Convention date, May 18, 1938. [Class 44] The locking means for the slider of a sliding- clasp fastener consists of a pin member 5 extending through the lower and upper plates 1, 2 of the slider and having teeth 7 to engage the underside of the stringers, the release being effected by a lever 12 which is loosely arranged below the bridgepiece 3 for the pull tab and is operated by pulling the tab 4 in either direction. The lever 12 is retained below the bridge piece 3 by forked ends 13, 14. When the tab 4 is pulled in the direction to open the sliding-clasp fastener the cross bar 19 of the tab engages the right-hand end of the lever 12 which is thus rocked about a fulcrum lug 15 but when the tab 4 is pulled in the closing direction its side limbs bear on the top of wing pieces 16 extending from the lever 12 ; thus in either case the locking pin 5 is depressed. The spring 10 for the pin 5 may consist of a rubber sleeve.

Abstract: 646,548. Drawing wire. SYNCRO MACHINE CO. June 4, 1948, No. 15177. Convention date, July 25, 1947. [Class 83 (iv)] A continuous wire-drawing machine comprises a number of drawing drums or blocks, each associated with a drawing die through which the wire passes to the block and with a storage drum to which the wire passes from the drawing block, the storage drum being driven from the drawing block through a slipping clutch. The machine comprises five drawing units 6-10 mounted on a housing 1 which contains a duct 4 communicating with an air impellor 2 and with branch ducts such as 5 and 55, leading cooling air to the drawing units. Each unit is driven by a separate motor through a belt and worm gearing 31. 32, the starting and stopping switches of the motors being operated by a common control bar 80 along the front of the machine, but each motor has a separate manually-operated speed control. The first four drawing units are similar to those shown in Figs. 3 and 5. A motor driven vertical shaft 33 is mounted in bearings 34, 37 supported from the housing and above the top of the housing it carries a drawing block 9<SP>1</SP> which is keyed thereto, and a winding or storage drum 9<SP>11</SP> which is rotatably mounted thereon and is driven by a friction annulus 43 on a disc 42 pressed by a spring 51 into contact with a disc 41 keyed to the shaft 33. The compression of the spring may be adjusted by a nut 52. A tubular member 46 projecting upwardly from the disc 42 surrounds the spring 51 and has an outer annular groove to receive a brake band with a radial projection 48 with which engages a pin 49 depending from a guide ring 9a rotatably mounted on the upper part of the member 46. Air from the duct 5 passes into a hollow ring 38 surrounding the lower edge of the drawing block and issues through a slot 39 on the lower exterior of the block and through slot 39<SP>1</SP> into the interiors of the block and drum, issuing on to the upper exterior' of the block through slots 40 and through the wire on the drum by way of openings 44. The drum is of sligntly larger diameter than the block. Fig. 6 shows the block and storage drum of the final unit. In this form, a spider within the block 21 carries a friction ring 60 and on it rests a friction ring 59 secured to the bottom of the drum 23 which is rotatably mounted on the vertical shaft 54. The drum is provided with upwardly extending cooling passages 64 and wire-receiving rods 63. In operation wire from a source passes through a die 11, Fig. 2, takes several turns round the drawing block of the first unit, round a pulley 12, then on to the storage drum of the unit, past the guide ring to a pulley such as 25 supported by an arm 26, thence down to a pulley 16 and on to drawing die 17 of the second unit, and so on.

Abstract: 502,246. Making hollow glassware. EVANS, W. E. (O'Neill European Machine Co. of Montreal) June 8, 1937, No. 15794. [Class 56] A glassblowing machine of the kind described in Specifications 315,154, [Class 56], and 470,326 is provided with a valve assembly for each mould unit, each assembly comprising a number of valves which are operated by stationary cams and control the application of suction and compression for gathering charges of glass and blowing the parisons. The suction valves and some of the blow valves are adjustable to vary the time of application to enable articles of different shapes and sizes to be made at the same time on one machine. Each assembly for the parison moulds comprises three valves mounted within a casing 1. The suction valve comprises a piston 2 within which an extension 14 slides, a grub screw 18 preventing relative rotation between the parts. The valve is normally held in its lower or closed position by a spring 5, and when raised provides communication between a port 8 and another port 10. A spindle 15 which screws into the extension 14 rotates in the part 2 and is prevented from moving longitudinally by collars 15a. Thus when the spindle is rotated by means of a knob 16, the extension 14 is raised or lowered relatively to the part 2 and the time at which the valve makes contact with, and is raised by, its operating cam can be adjusted. A second valve, 19, admits compressed air for creating the initial blow openings in the parisons, while a third valve, 24, controls the supply of air for cooling the neck pin after withdrawal from a parison. A similar valve assembly is associated with each of the finishing moulds, but in this case two of the valves are adjustable. Specifications 502,339 and 502,340 also are referred to.
