Title: Improvements in or relating to knitting machines
Inventor: START ERNEST
IPC: D04B15/66
Filed: 1954-09-30
Abstract: 782,578. Knitting-machines. COTTON, Ltd., W. Aug. 18, 1955 [Sept. 30, 1954], No. 28168/54. Class 74 (2). Detector means 8, disposed in advance of the operating station of a pattern chain or band 3, responds to a misplaced part associated with the chain, by operating a detent control device to cause sustained operation of a stop motion or other device, whereby the ill effects of the detected misplacement are obviated; and manually operated means is provided for re-setting the detent control device with the stop motion again unoperated. Misplacement or abnormality of studs 2 or cross bars of the pattern chain causes a suitably gated detector 8 to be swung clockwise (as seen) about its supporting shaft, against the action of a spring 125 and so, through a link 23 and lever 24, to slide a detent member 21 to the left, allowing a square-sectioned member 20 hitherto held by the surface of the member 21, to be swung to the floor of a recess 22 in the member, by the action of a spring 118 on the lower arm of a lever 14 which, with the member 20, is fixed to a rock shaft 15. The upper end of the lever 14 is thus moved away from the operating button of a snap-action switch 13, which thereupon closes to operate the stop motion. The operation of the stop motion cannot thereafter be terminated until the member 20 has been swung out of the recess 22 (for which purpose it ends in a handle) when the lever 14 again depresses the plunger of the switch 13 and, assuming that the abnormality has been removed, the spring 125 may return the feeler 8 and so re-set the detent member 21. The lever 24 may be connected to the member 21 by a pivot, or by slot means, in which latter case a spring 25 counteracts any play. Specification 711,149 is referred to.

Title: An eyelash curler
IPC: A45D2/48
Filed: 1952-11-10
Abstract: 714,134. Eyelash curlers. KISLIG,' E. Nov. 10, 1952 [Nov. 10, 1951], No. 28220/52. Class 131. In an eyelash curler, comprising two arcuate jaws movable relatively to each other in a direction parallel to their axis of curvature to a position in which they overlap, the jaws are rotatable angularly with respect to each other. As shown, a jaw 1 has rigid connections 2 to a handle 3 longitudinally bored to receive a stem 4 which is movable axially and angularly and provides a support for connecting wires 7 of a jaw 5 which is chanelled to receive a rubber pad 6. A spring 10 urges the jaw 5 to a position in which the jaw 1 rests on the pad and is overlapped by the serrated edge 8 of the jaw 5 to curl eyelashes inserted between the jaws. In use the jaws are opened by retraction of a knob 9 and the jaw 1 laid against the eyelid the closing of the jaws on release of the knob 9 being arrested by finger pressure on an arm 16 when the points of the serrated edge 8 engage the eyelashes to " comb '' them. The jaw 5 is now turned by means of the arm 16 so that the eyelashes are directed away from the nose and the upward bending of the eyelashes completed by releasing the arm 16. In a modification the operating knob 9 and a rotatable ring member on the base of the handle are provided with projections which abut to arrest the closing action of the jaws when the outward bending of the eyelashes is due, full closure of the jaws being achieved only when the knob 9 has been rotated. A setting for right and left eyes is obtained so that the eyelashes may be bent only in a direction away from the nose.

Patent GB-188317-A (GB)
Title: Improvements in apparatus for limiting the power-output of steam turbines and gas turbines
IPC: F01D21/14
Filed: 1922-10-19
Abstract: 188,317. Akt.-Ges. Brown, Boveri, et Cie. Nov. 3, 1921, [Convention dale]. Stop - gear. - A valve-contrclling device responsive to the pressure in the interior of a turbine provides that the turbine inlet-valve is first adjusted on the said pressure exceeding a predetermined limit, and is shut down rapidly so as to stop the turbine in the event of a sudden dangerous increase of pressure. A diaphragm b is subjected on the side a to the pressure inside the turbine and on the other side to the pressure of an adjustable spring c. The diaphragm actuates a two-part spindle e, the lower part of which carries a valve f. Downward movement uncovers a port k, permits pressure oil from the inlet-valve system to escape by a pipe h and thereby reduces the inlet-valve opening. Engaged between the two parts of the spindle e is the end of a pivoted lever l which carries a roller m bearing on a knife-edged cam n pressed upwards by a spring p. After a limited downward movement of the lever l, the roller m passes to the right of the edge of the spring- pressed cam n and the latter causes a sudden rapid opening of the valve f against a spring o, and the turbine is stopped. The lever l is reset by hand, and may be used for stopping the turbine quickly by hand. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a statement that two separate control mechanisms may be used, one for limiting the power-output, the other for stopping the turbine. This subject-matter does not appear in the Specification as accepted.

Title: Egg handling machine
Inventor: WILLSEY CHARLES HOWARD
IPC: B65B23/06
Filed: 1969-06-05
Abstract: 1,241,779. Endless conveyers. SEYMOUR FOODS Inc. 5 June, 1969, No. 28579/69. Heading B8A. Eggs to be orientated are delivered in random disposition by an endless belt 21 to the first of a series of slats 26, 27, 28, 29 each of which has a number of shaped pockets (41), Fig. 6 (not shown), to receive the eggs. The slats, which provide a downwardly inclined path away from the belt 21, are each mounted on a driven shaft 31, 32, 33, 34 such that as alternate slats are pivoted about their downstream end the eggs proceed in step-wise motion down the slats and become aligned with their long axis extending transverse of the direction of motion. The eggs are then advanced beneath sensing devices 80 to a stationary slat 30 of a width sufficient to receive two transverse rows of eggs, positioned over the receiving end of an intermittently driven endless conveyer 11. The leading row of said two rows of eggs is held against a cross-bar 52, a plurality of which are mounted on the endless conveyer 11 at longitudinal intervals of less than the largest diameter of an egg, such that where a full row is detected by the sensors 80 drive to the conveyer 11 is initiated whereupon the eggs in the said leading row are delivered to the conveyer and are each suspended at two points on their periphery, said points lying substantially in the plane of the short axis of the egg. The eggs are then advanced, upon subsequent motion of the conveyer, beneath a number of rotating discs 53 arranged in pairs corresponding to the longitudinal lanes of eggs. The discs of each pair are resiliently spaced apart by a spring 56, the arrangement being such that the discs of each pair engage the egg on both sides of the plane containing the short axis and rotate the eggs about an axis parallel to the direction of conveyance to align the eggs with their pointed ends lowermost. On subsequent movement of the conveyer each row of eggs is condensed by means of converging guide bars (60), (61), (61<SP>1</SP>), Fig. 1 (not shown), for delivery to a packaging machine, not shown.

Abstract: 285,941. British Celanese, Ltd., Dreyfus, H., and Ellis, G.. H. Oct. 23, 1926. Addition to 281,084. Yarns and threads, treating with liquids.-Relates to the loading of yarns, threads, &c. composed of or containing cellulose acetate or other cellulose esters, or cellulose ethers, with metals such as tin, zinc, aluminium, bismuth, and tungsten. The process of the parent case is modified by employing for the loading a solution containing a loading metal and a thiocyanate, and in which the thiocyanate radicle is in a proportion not exceeding that chemically equivalent to the loading metal. In examples, the goods are treated with solutions containing proportions of stannic chloride and ammonium thiocyanate corresponding with the salts,-Sn(CNS)4, SnCl.(CNS)3 and SnCl2(CNS)2. The loading metal may be fixed by treatment with a solution of tannic acid, a phosphate or a silicate, or even by washing with water, preferably water containing lime or alkali. The process may be applied to goods containing other fibres such as wool, cotton, natural silk or artificial silk of the cellulose type. In addition to the loading, the goods show less tendency to slip, ladder or split, and they exhibit greater fullness and volume.

Abstract: 753,332. Conveyers. EXPRESS DAIRY CO. (LONDON), Ltd. Sept. 2, 1954 [Oct. 19, 1953], No. 28722/53. Class 78 (1). [Also in Group XVII] A device, particularly for crating or uncrating bottles, comprises one or more grabbing heads vertically reciprocable to grab and raise a number of bottles on one conveyer, the head being swung by a swashplate mechanism about a vertical axis to deposit the bottles on another conveyer. Pneumaticallyoperated machines having two heads 42, 42a are described, which heads may have bottlegripping mechanism as described in Specification 709,421. The heads are carried on supporting means rotatable about a fixed shaft 31 and are secured each to a cylinder 41, the piston of which is carried on a rod 43 attached to a piston in a cylinder 40 secured to the supporting means. The supporting means is rotated by one or other of rollers 35, 36 engaging a fixed swash-plate 37, the rollers being carried by piston rods operating in cylinders 38, 39. Vertical movement of the rollers also causes one or other of a pair of brake pads 136 to engage a fixed plate 137 to check the rotation of the supporting means. The grabbing means on the heads is operated by a piston and cylinder device 44. In a bottle crating machine, bottles advance along a conveyer 45 having guides 51 and are checked against a plate 51a. A head descends the stroke of the piston in the cylinder 41 and grabs the assembled bottles, the adjacent bottles being checked by the pressing inwardly of hinged flaps 52, 53 at the conveyer sides. The bottles are carried through 180 degrees and the head lowered the full length permitted by the cylinders 40, 41 to deposit the bottles in a crate 49. The crates are advanced on a conveyer 46 and the first filled crate 49a past the filling station is checked by a fixed stop 261, being released after the filling of the crate 49, by the upward pivoting of bell-cranks 62 (Fig. 4), rollers 63 pushing the edge of the crate 49a over the stop. In de-crating, the machine as above described is modified so that the bottles are removed from a crate on the conveyer 46, the crate sides being gripped during emptying, and swung over to the conveyer 45 for release slightly before the supporting means comes to rest. Both crating and de-crating embodiments are fully automatic, the movement of the heads operating valves initiating the rotary movements, and the gripping and stopping devices on the conveyers being operated by cams 138, 139, 141 on the supporting means opening valves delivering air to their cylinders.
