Title: Fastenings
IPC: F16B37/04
Filed: 1963-07-23
Abstract: 1,039,766. Fasteners. V. F. ZAHODIAKIN. July 23, 1963 [Dec. 19, 1962], No. 29165/63. Heading F2H. [Also in Divisions B4 and E2] A releasable fastener comprises a hub 12, Figs. 1-5 (not shown), having a screwed bore 14, flats 24, and slots 20, and a locking member 27, Fig. 9 (not shown), carried by the hub and secured to a member 32, Figs. 6 and 7 (not shown), having a bore 34, cut-outs 35, and upsets 36. A tool 40, Fig. 10 (not shown), is used to attach and detach the fastener to member 32 and comprises a handle 41, a shaft 42 fixed to the handle, a screwed position 43 on the shaft, and a member 44 slidable on the shaft. To attach the fastener to the blind side of plate 33, Fig. 5 (not shown), lock 27 is forced downwardly over hub 12 so that legs 31 enter slots 20 and the hub is screwed on to tool 40. The tool is first inclined as at A, Fig. 5 (not shown), and along with the fastener is partially inserted through hole 34 until shaft 42 engages the hole. The assembly is then oriented until the complete fastener passes through the hole and lies in the dotted line position of Fig. 1 (not shown). The tool is pulled downwardly to flex the resilient legs 31, and is then rotated until the legs snap into openings 35, and portions 17 lie in upsets 36; thus holding the fastener in plate 33. In a modification, Figs. 11, 12 (not shown), openings 50 and upsets 52 are formed on an intermediate plate 47 secured to member 48, which may or may not have a bore 51. In a further modification, Fig. 13 (not shown), openings 55 and upsets 58 are adjacent each other. In a still further modification the fastener is in the form of a bolt 65, Figs. 15, 16 (not shown), which comprises a circular head 67 having arms 68, formed with slots 71, and a resilient locking member 72 screwed to the head at 73, and having legs 75 which project into slots 71. Member 76 has a hole 77 elongated at 78 so that the bolt head can be passed through the hole in member 76 and rotated, thus flexing legs 75 until they snap into slots 80 in member 76 and portions 68 are held by the upsets 79. The tool of Fig. 10 (not shown) may be replaced by a tool 82, Fig. 17 (not shown) which has a screwed part 88 pivoted to shank 84 at 90 the part being held in the required pivoted position by a spring-urged pin 95 which engages the end of the shank.

Apparatus for manufacturing tubing from metal strip in a plurality of forming stages is characterized in that all the forming means individual to a single forming stage are carried upon a single support plate arranged transversely to the axis of progression of the strip, said plates being adjustable in the direction of progression of the strip. Removable plates 1, secured in slotted supports 2 fixed on a base 3 and adjustable longitudinally along a key 4, have mounted therein rollers 6, 7, 8, 9 which form strip fed therethrough into a longitudinally-seamed tube which is then welded by means mounted between plates at 5. The rollers may be freely mounted in the plates, the strip being pulled through or carried on a transversely flexible belt which passes through the forming means with the strip, or the rollers on one or more plates may be driven. The plates are closely spaced so that the strip does not spring open between them. The central rollers 6 of the plates support and bend the strip and have profiles of a radius greater than that of the finished tubing and which decreases in successive stages from plate to plate while the side rollers 7 and 8 form the sides of the strip equal to that of the finished tubing. The rollers 9 guide a cable to be sheathed and press upon the edge of the strip. The rollers may be adjustable in the plates. Rollers 30, Figs. 7 and 9, accommodated in a cruciform slot 15 in a plate 11 are carried by forks 32, adjustable along keys 17 on the plate 11 by screws 29, the bottom roller may not however be adjustable.

[Also in Division F2] In one modification of a valve according to the parent Specification, the obturators are formed by a single rotary plug 6 and the outlet pipes 2, 3, 4, 5 are arranged side-by-side around the plug axis. The axes of the outlet pipes may be coplanar and perpendicular to the plug axis (Figs. 1 and la, not shown), the plug being part cylindrical; or normal to the plug and inlet axis (Fig. 4, not shown), the plug 6 being a sector of a circular disc; or may be generators of a cone coaxial with axis of a conical plugthe inlet 1 may be coaxial with the plug (Fig. 2a, not shown), or inclined to it (Fig. 3, not shown), to allow the plug bearings to be outside the inlet. In another modification the valve is separated into a plurality of valve elements the single rotary plugs of which are rotated together for example by a gear train (Fig. 5b, not shown). Each element, which may have an axial or radial inlet may have one or two outlets. In a further modification (Figs. 7 and 8, not shown), each outlet has an internal wall rounded to smooth the flow through the angle leading into it, and to provide a throat the width of which measured along the plug axis, varies in the direction in which the plug moves, so that the throat area varies with plug position in a predetermined way. The wall may be extended upstream into the plug chamber (Fig. 8, not shown), a slit 14 being provided to permit the plug to pass.

Abstract: 1,118,096. Measuring thickness electrically. BRITISH IRON & STEEL RESEARCH ASSOCIATION. Sept. 11, 1967 [July 4, 1966], No. 29908/66. Heading G1N. A method of measuring thickness, particularly of a moving sheet leaving a rolling mill, comprises applying a frequency modulated micro-wave beam to a pair of cavity resonators tunable by the sheet and disposed one on either side thereof; determining the frequency at which each resonator resonates, and calculating the thickness of the sheet from the determined resonant frequencies and the known distance between the resonators. - Thus movement of the strip up and down between the resonators will not affect the calculated thickness. The resonant frequencies may be determined by the change in amplitude of signals from the cavity Figs. 1, 2 (not shown) or phase change at resonance Fig. 3 (not shown). In Fig. 1 the amplitude change is used to lock frequency meters driven from the sweep-frequency-modulator. In Fig. 2 the rampvoltage-generator for the frequency-sweep-modulator provides a frequency-representative signal which is gated to an arithmetic unit by AND circuits at a pre-set signal level from the resonators. In Fig. 3 the AND gates are triggered by a phasemeter.

Title: Esters of amino acids
Inventor: DUXBURY FREDERICK KEITH
Filed: 1956-10-03
Abstract: Secondary esters of amino acids of the formula NH2.CH2[CH2]nCOOR1, wherein n = 3 to 8 inclusive and R1 stands for a secondary hydrocarbon radical, such as isopropyl, sec.-butyl, sec.-amyl or cyclohexyl, are prepared by the catalytic hydrogenation, in the presence of ammonia, of the appropriate secondary esters of cyano acids having the formula CN[CH2]nCOOR1.  In Example 2 a mixture of isopropyl o -cyanovalerate, liquid ammonia, finely-divided nickel catalyst, and isopropanol is charged into an autoclave equipped with a stirrer.  Hydrogen is forced into the vessel until the pressure is approximately 120 atmospheres, and the mixture is heated at 80 DEG C. for 1 to 2 hours.  The reaction product is filtered and then fractionally distilled to isolate isopropyl o -aminocaproate.  In Example 4, sec.-butyl o -aminocaproate is obtained by hydrogenation of sec.-butyl o -cyanovalerate.  In Example 3, a mixture of isopropyl o -cyanocaproate, liquid ammonia, cobalt-on-kieselguhr catalyst and hydrogen is heated at a pressure of 240 atmospheres and a temperature of 120 DEG  C. for 2.5 hours to give isopropyl o -aminoheptanoate.
