Title: Improvements relating to the manufacture of slide fasteners
IPC: A44B19/58
Filed: 1955-11-11
Abstract: 788,376. Sliding clasp fasteners. CUE FASTENER, Inc. Nov. 11, 1955 [Nov.15, 1954], No. 32325/55. Class 44 [Also in Group XXII] In making coil-type sliding clasp fasteners gaps are formed in a length of coil each loop of which is attached to a supporting strip by apparatus which severs two or more loops and disengages the portion of the coil between the severed loops or the outer severed loops from the strip. The strips are severed at the gaps to form the individual coil units for the fasteners which may be as described in Specification 548,819. A blade 15, Figs. 1 and 8, having a straight cutting edge and of width equal to the gap is reciprocated horizontally by a crank 36 to cut through one side of all the loops which are to be removed. The strip 11 is held between gripping members 17 and 18 one of which is pivoted and actuated against the action of a spring by a cam 70. After cutting one side of the loops, the blade 15 holds the other side of the loops against a spring-loaded backing member 16 and during the last part of its stroke disengages the loops from the strip 11. A stop 46 on the blade engages the backing member 16 to maintain sufficient clearance. During the return stroke the waste loops are stripped from the blade 15 by a member 23 pivotally mounted and oscillated by a cam 59. The machine is operated manually or automatically under control of a one revolution clutch. The blade may have projecting end portions so that both sides of the end loops of the gap are cut. In a modification the blade is shaped as shown in Fig. 10 and has sharpedged notches 81a which sever alternate loops and blunt-edged receses 84 which engage the intervening loops to remove a portion of the coil. The backing member is dispensed with. In a modified machine, Fig. 14, for forming gaps in two coils 92, 93 at once, two blades 95, 96 are carried by a cam reciprocated crosshead and co-operate with a spring-mounted backing member 94. The strips 90, 91 are gripped by clamps actuated by spring-loaded plungers on the crosshead and a striping member 97 between the blades is reciprocated by a cam.

Title: Improvements in or relating to apparatus for deshelling seeds having hard shells
IPC: A23N5/00
Filed: 1919-12-30
Abstract: 160,933. Mitchell, G. Dec. 30, 1919. Hubling. - Relates to apparatus for de-shelling seeds having hard shells in which the seeds are thrown by a rotor or bladed impeller carried by a vertical shaft against a casing having faces at right-angles to the line of flight of the seeds. Adjustable feeding means such as a feed-hopper with a telescopic outlet is provided for reylating the feed of the seeds to the centre of the impeller. As shown, the impeller D consists of a disc D<1> having on its upper face a central conical portion D<2> and curved ribs 'or blades D<3> extending from the circumference of the disc to the base of the cone. An annulus D<4> connects the upper portions of the blades D<3> from their outer ends to about the middle of their lengths. The curvature of each blade is greater at its inner end than at its outer end, so that the latter is approximately radial. Each blade is shallower at its outer end than at its inner end, and the ribs D<3> extend along the annulus D<4> so as to form a second set of cells D<6> beneath the detachable cover B of the hopper-shaped casing A. The flat faces E on the inside of the casing A set at right-angles or approximately at rightangles to the lines of flight of the seeds are pureferably inclined forward slightly so that the shells and kernels in rebounding from the faces are directed below the impeller. The cover B conforms in shape to that of the top of the blades D' and has a central feed conduit B<1> carrying a hopper B<2>. The sleeve-valve F within the conduit B<1> is adjustable by means of a pivoted lever F<1> and'hand-wheel F<6>. A blast of air for separating the fragments of shell from the kernels is drawn through apertures G in the cover B around the conduit B' and a rotary disc-valve G<1> operated by means of a handle is provided to regulate the blast. The vertical shaft C carrying the impeller is driven by bevel-gearing C', H from a shaft H<1> which is mounted in a bearing H<2> on the wall of the casing A, and extends into the horizontal tubular chamber A<2> in the casing. The outer end of the shaft H<1> may carry a set of stepped pulleys K arranged to be frictionally driven by a second set by means of a jockey roller carried on a weighted lever slidably fulcrumed on a rod carried by a bracket. The pieces of broken shell can be withdrawn by means of suction through a conduit connected at the bottom of the casing, the kernels falling through the outlet A'.

Title: Improvements relating to liquid-flow indicating or recording instruments
Inventor: HAIGH RICHARD WOOLLISCROFT
IPC: G01F3/18
Filed: 1949-12-23
Abstract: 678,311. Electric speed indicators. LUCAS, Ltd., J. March 21, 1951. [Dec. 23, 1949] No. 32928/49. Class 40 (i). [Also in Group XL (b). The invention relates to liquid flow meters of the kind wherein the liquid-flow rotates an output member, e.g. a disc h, through piston and crank mechanism c-g, so that for a constant velocity of liquid-flow the output member rotates at a constant average speed which is, however, subject to a cyclic variation due to the nature of the drive. According to the invention the output member h drives a disc j provided peripherally with markings spaced irregularly to compensate for these speed variations. The markings which may be magnetic, co-act with a pick-off, e.g. k to produce electric pulses, so that for a constant liquid-flow the pulses are produced at a constant rate proportional to the flow. The pulses are amplified at m and operate a frequency meter n which controls an oscillograph o or a recorder. The markings on the disc j may alternatively, be visible and co-act with a photo-electric pick-off or consist of depressions as in a gramophone record co-operating with a suitable pick-off.

Title: Improvements in or relating to shaping or dressing devices
IPC: B24B53/065
Filed: 1952-12-30
Abstract: 712,809. Copy-turning. ALLEN, R. Dec. 30, 1952, No. 33027/52. Class 83 (3). [Also in Group XXIII] Work having a shape comprising a straight portion blending with two radiused portions is shaped by a tool which is guided along a continuous path corresponding to the shape by adiustable guide means. The latter include two plates 16, 17 and a sliding member 18 each of which has an arcuate recess to form a slideway for an arcuate tongue 25 on the tool holder 44. In operation, the plates 16, 17 are adjusted by screws 36 until they are separated by a distance corresponding to the straight portion of the work. Pegs 41 secured to the plates enable this distance to be accurately determined by a slip gauge, a micrometer or a gauge plate having holes to receive the pins when they occupy the required positions. The tool holder, starting from a position determined: by a stop 49. in the recess of the plate 16, is swung downwardly in an arcuate path by a handle 47 until the tongue 25 fully occupies the recess in the slide 18 and is prevented by engagement with the lower edge of the plate 17 from further movement in that recess. The slide 18 is now compelled to move by the pressure applied to the handle 47 until the recesses in the slide 18 and plate 17 are in alignment and the tongue 25 can complete its movement to a stop 50. The tool is adjustably clamped by a screw 46 in the holder 44 to give the desired radius at each end of the straight portion of the path produced by movement of the slide 18. The housing of the device is fitted with strips, such as 31, to engage recesses in the plates 16, 17 and the slide 18 to guide the movements of these members and is enclosed by dust shields. Apertured lugs 19 are provided at each end of the housing for engagement by the headstock and tailstock of a machine.

Abstract: 521,301. Protective cut-out arrangements. FORREST, J. S. Nov. 14, 1938, No. 33044. [Class 38 (v)] A conductor B or piece of apparatus F is protected against leakage or arc-over by means of a guard ring A or other conductor which is mounted on or near an insulator E of the conductor or apparatus adjacent the earthed end of the insulator and connected to earth by conductor C, such that a protective relay in C trips the breakers affected. The relay may be energized by a current transformer in the conductor C, or the latter may contain a spark gap or low resistance, the voltage across which energizes the relay. Where several insulators of a protected zone such as a busbar installation are so equipped, the conductor C may have a common protective relay. If the guard ring reduces the insulation value of an insulator-string, another insulator may be added to the string.
Patent GB-394678-A (GB)
Title: Improvements in or relating to the manufacture of cyclic diethers
Filed: 1931-11-30
Abstract: In the production of cyclic diethers by condensing aldehydes or their polymers or ketones with glycols or polyhydric alcohols, the ether is withdrawn from the reaction vessel continuously with its production, preferably by maintaining a temperature such as to cause distillation of the ether.  The reagents may be supplied continuously to a reaction vessel containing a reaction medium such as glycol and an etherification catalyst.  Suitable catalysts are sulphuric, phosphoric, hydrochloric and benzene sulphonic acids, and salts having an acid reaction such as zinc and ferric chlorides but excluding the catalysts mentioned in Specification 394,679.  The reaction product may be fractionally distilled, if desired, after first adding sodium bisulphite to fix unchanged aldehyde and/or sodium carbonate to neutralize acidity, and sodium chloride to separate water.  The partially purified products which contain dioxane, especially when free from aldehyde and acidity, may be used as solvents or swelling agents for cellulose acetate and other cellulose derivatives.  A number of methylene and ethylidine diethers are mentioned as products.  In an example, a mixture of glycol, paraformaldehyde and sulphuric acid is heated at 140 DEG  C., and glycol and paraformaldehyde are added at the same rate as the distillate collects; the distillate is treated with sodium bisulphite to remove aldehyde, sodium chloride to separate water, and anhydrous sodium carbonate to remove acidity; it is then dried with calcium chloride and re-distilled.
