Filed: 1948-01-27
Abstract: 639,905. Eyelets. BRITISH UNITED SHOE MACHINERY CO., Ltd. (United Shoe Machinery Corporation). Jan. 27, 1948, No. 2385. [Class 43 [Also in Group XXXVI] The head flange 11 of an eyelet is provided on its gripping face with at least four radial ribs 13 (eight ribs being shown) which radiate from the barrel 10, the end of the barrel remote from the flange having weakened parts in register with the ribs so that the barrel will split into prongs during setting. The face of the head flange 11 remote from the barrel 10 is indented to provide on the gripping face of the flange eight equally spaced radial ribs 13 separated by depressions 14 which are wider than the ribs. The edge of the flange 11 is curled up so that an annular trough is formed round the barrel. The end of the barrel remote from the flange has in register with the ribs, eight nicks 9, from each of which a score-line 15 runs axially of the barrel. To set the eyelet on stranded wire for use as a terminal element one or other of the machines described in Specification 625,306 may be used. As the eyelet, which may be of moderately hard brass, is clenched between the dies of the machine the barrel 10 splits along the scorelines 15 into eight prongs which bend round the wire and are tucked into their corresponding depressions 14 in the flange 11, the lower setting die having an annular setting shoulder of sufficient curvature to bend the prongs well back upon themselves ; at the same time the ribs 13 and depressions 14 of the flange 11 result in undulation of the wire which is thus securely gripped.

Jan. 26, 1931, No. 2480. [Class 74 (ii).] The sinker cams 35, 36 of a flat knitting- machine having sliding needles are mounted so that they may occupy alternately at successive courses two positions situated on each side of the knitting position determined by the needle cams. Preferably the cams 35, 36 are controlled by slots 52, 53 in a plate 39 so that they are moved from loop-sinking position to holding-down position as they are moved endwise. The presser cams 55, 56 may be pivotally mounted so as to be rocked alternately into operative and inoperative positions. The invention may be applied to a machine such as is described in Specification 342,679 having a variable knitting-cam stroke. In an alternative construction, for machines having latch needles, a single sinker-operating cam may be employed, movable from one position to another at the end of each stroke. Specification 371,821 also is referred to.

Abstract: 665,123. Toggle mechanism. MINISTER OF SUPPLY. Jan. 27, 1950 [Jan. 28, 1949], No. 2481/49. Class 80 (iii). [Also in Group XXIX] A transmission mechanism between linearly - moving, coaxial members has provision for varying the ratio of movement of the driving member to that of the driven member. The mechanism is shown applied to valve apparatus for a liquid fuel motor to vary the relative amounts of movement of a driving valve 13 which controls a fuel outlet 54, and a driven valve 14 controlling an oxidant outlet 55, the valve 13 being actuated by a control 11. The valves 13, 14 are provided with extensions 24, 25 whose ends are countersunk to receive balls 26, 27 respectively. The balls are urged together by a spring 38 (Fig. 3) acting on the valve 14, and are spaced by rollers 28, 29 which also contact cam surfaces 36, 37 provided by grooves in a pair of pivotally mounted jaws 39, 40. The inclination of the surfaces 36, 37 is varied to alter the transmission ratio by an axially movable member 41 having inclined surfaces 42, 43 and connected to control rods 48, 49. The member 41 is located by springs 56, 57 and adjusting nuts 50, 51 on the control rods, adjustable members 58, 59 compensating any variations in the strength of the springs. Movement of the members 13 and 41 may be effected by fluid means dependent on motor conditions, velocity, altitude &c. The cam surfaces 36, 37 may be of other than rectilinear form. In a modification, the balls 26, 27 and rollers 28, 29 are replaced by a pair of ball bearings contacting the surfaces 36, 37 and carried -by pairs of links pivoted to the driving and driven members.

Title: Process of providing aluminium or its alloys with line and/or surface etchings for printing purposes
IPC: C23F1/02
Filed: 1924-01-31
Abstract: 227,638. Straub, W. Jan. 31, 1924. Etching.-Printing-surfaces of aluminium or its alloys are etched by means of a, solution of a mercury salt. If sharp shallow lines are required, the solution is washed off after a few seconds and the treated surface exposed to moist air. If deep etching is desired, the treated surface is immersed in a solution of any ordinary etching agent such as acetic or sulphuric acid or an alkali. Broad surfaces may be etched by applying the mercury salt solution by means of a brush or sprayer and subsequently treating them to the action of moist air or to ordinary etching reagents. In the latter case. different sections of the surface may be treated with different reagents or for different periods to produce varying grades of tone.

As shown, recesses 7 are provided in the periphery of the opening to allow the lugs 6 to pass, after which the bush is turned through 90 degrees to allow a locking piece 9 to be inserted into one of the recesses 7 and into a notch 8 in the bush. The nozzle which is screwed into the bush prevents the locking piece from moving out of the recess. In another arrangement, Figs. 3-5 (not shown), the bush is of resilient material, is slit longitudinally, and includes a projection on its outer wall, which constitutes the locking device. In a modification, the collar extends for only a part of the periphery of the bush and is extended to form the projection. Also the collar is let into the surface of the base-plate and a washer is interposed between the latter and the nozzle. When a soft resilient material is used, the slit or slits in the bush may be dispensed with.
