Patent GB-1109414-A (GB)
Title: Improvements in or relating to yarn packages and to methods of producing them
Inventor: JOHNSON BRYAN KINGSLEY
IPC: B65H55/00
Filed: 1965-10-15
Abstract: 1,109,414. Yarn packages. IMPERIAL CHEMICAL INDUSTRIES Ltd. 26 Sept., 1966 [15 Oct., 1965]. No. 43828/65. Heading B8M. A yarn package comprises a body of yarn 1 wound in a shaped build on a bobbin or tube 3, a transfer tail 5 being wound at one end and a waste receiving device 9 being provided at the other, the final lengths of yarn 11 comprised in the package being wound on the device 9. The waste receiving device 9 is removable and is preferably a sleeve or spool. The yarn is preferably wound in a double taper build and may be a continuous filament yarn of synthetic polymeric material, e.g. polyamide, polyester, polypropylene, which is bulked or latently-bulked by a crimping treatment. In the case of a spool being used as the waste receiving device 9, the spool may be detachably secured to the tip of the spindle on which the bobbin is mounted. The package is formed by first winding the transfer tail, e.g. spaced helical turns, at one end of the tube, then building the body of yarn, and finally winding on to the waste receiving device which is spaced from the yarn body at the opposite end to the transfer tail. The winding is slowed and brought to a stop during winding on to the waste receiving device. Winding may take place on a draw-twist machine or a ring-spinning frame.

Title: A signalling device for connection into a conduit of a fluid system to detect fluid flow therein
IPC: G01P13/00
Filed: 1959-12-24
Abstract: 868,278. Fluid flow indicators. AMERICAN DISTRICT TELEGRAPH CO. Dec. 24, 1959 [Dec. 31, 1958], No. 43858/59. Class 69 (1). [Also in Group XXXVIII] In a sprinkler supervisory system a flexible vane 70 with a thickened or semi-rigid portion preferably formed as ribs 72 is inserted into a water supply conduit through a composite water-tight housing 10, 22 secured to the conduit 16 by a U-bolt. Any substantial flow of water, due, for example, to the opening of a sprinkler head, causes the vane 70 to be displaced about its pivot 64 until its shank 62 abuts against the neck 26 of the housing 22, the vane itself bending under the water-pressure until it lies against the side of the conduit, as shown at 60. The displacement of the shank 62 moves a rod 42 and thus releases a delay switch 56 which, after a predetermined time, closes contacts 57 to send a signal to a central station. Small pressure changes in the supply mains cause a flow which is insufficient to cause the delay switch 56 to close its contacts 57 before pressure on both sides of the vane 70 is equalized and a spring 44 restores the vane 70 to its normal vertical position. The speedy equalization of pressure is aided by a slight clearance between the vane 70 and the conduit 16 and by the flexibility, particularly of the edge portion, of the vane 70. The vane 70 is preferably made of polyethylene and because of its flexibility may be withdrawn for inspection without removing the housings 10, 22.

A load sensing roller 38 controls the motor 33, so that the tension is brought back to the predetermined value if fluctuations occur due to variations in the gearing internal friction.

Patent GB-440470-A (GB)
Abstract: 440,470. Tills. UNITED AUTOGRAPHIC REGISTER CO., 5000, South California Avenue, Chicago, U.S.A. May 4, 1935, No. 13349. Convention date, May 7, 1934. [Class 116] [See also Group XIX] The operation of the recording mechanism of an autographic recorder unlatches a lid to give access to a cash receptacle. In the embodiment shown in Figs. 1 and 3, a cash receptacle D is situated to one side of an autographic recorder B of usual construction. Upon the depression of a handle 18 to advance the strips '16a, a lid D is unlatched and swings open to uncover the cash receptacle. The record strip is stored in a compartment C having a lock C<1>. A latch 51 is operable from within the normally locked record compartment to release a lid E<1> giving access to a deposit compartment E. The lid D<1> of the cash receptacle is provided with side blinds 23 and is normally held in closed position by the co-operation of a stud 38 on one of the blinds with hooked arms 36 on a shaft 31. The operating handle 18 is connected to the shaft 31 through a lost-motion device and, at the end of its depression, rocks the shaft and arm 36 to release the lid. Upon release, the lid is moved rapidly clockwise by a spring plunger 32 abutting one of the blinds, this opening movement being completed by spiral springs 25 on the pivot shaft 24. A control shaft 39 is rotatable by a key 41 in both directions from normal position. Rotation in one direction, by a lug 44, raises the hooked arms 36 permanently to release the lid. Rotation in the other direction engages a lug 42 in an aperture 43 in one of the blinds to lock the lid. The cash receptacle comprises a cash drawer 20<a> slidable outwards to uncover a note tray 19. In the embodiment shown in Fig. 9, the cash receptacle D<2> is normally covered by a roll top D<3>. The top is locked in closed position by the engagement of hooks 61f with latch arms 70 on a shaft 69. Depression of the operating handle 18 serves through a lost-motion link 67 to rock the shaft and release the top. Upon release, the opening movement of the top is started by spring-urged arms 75 abutting projections on the top. Opening is completed manually by a handle 61e. A spring plate 60<c> prevents the falling of coins to the left of the cash compartment. The hammer 72<a> of a bell 71 is operated by an arm 73 of the shaft 69 upon the opening and closing of the top.

Title: Improvements in or relating to electrochemical machining
IPC: B23H5/02
Filed: 1965-10-18
Abstract: 1,129,268. Electrolytic Machining. C.W. MORLE (Kiyoshi Inoue). Oct. 18, 1965, No. 44098/65. Heading C7B. In a process for electrolytic machining to form a cavity in a workpiece by means of an electrode having a machining face portion and a supporting shank portion, electrically insulating material is deposited from the electrolyte on the lateral walls of the cavity proximate the shank portion of the electrode to form an insulating sheath limiting further electrolytic action, the formation of an insulating layer on that part of the workpiece proximate the machining portion of the electrode being prevented by providing periodic spark discharge between the said machining face and the workpiece. The coating substance may be formed by electrolytic oxidation or reduction of a material soluble in the electrolyte or by reaction between a solute in the electrolyte and one or more ions found in the region of the gap; e. g. when the workpiece contains iron a soluble phosphate or long chain fatty acids or benzoic acid in the electrolyte will form insoluble iron phosphate in the gap. Preferably the power supply for applying the erosion current is an alternating-current source at 40-100 cycles per second with means for reducing the amplitude of pulses of one polarity, the low amplitude-pulses themselves having a superimposed variation of 400-10, 000 cycles per second. An erosion current of this form is particularly useful for machining binary compounds such as carbides. The electrolyte may comprise an aqueous solution of soduim chloride, a fatty acid and disodium phosphate. 1-5% by weight of sulphuryl chloride or soduim silicate and 5-20% by weight of acetyl chloride may also be present.

The closed loop arrangement shown may be duplicated whereby movement of the lever 14 normal to the plane illustrated would operate another identical arrangement. In a modification, the valves 9a, 9b may be omitted whereby the springs 12a, 12b accommodate thermal expansion, the bleed holes 8a, 8b simply serving to damp out any relative movement, or, alternatively, the damping arrangement may also be omitted whereby the springs 12d, 12b act directly on the gear lever. In a further embodiment, the master pistons 1a, 1b are simply directly connected to the gear lever 14, with the whole of the inner piston, cylinder and reservoir omitted, and thermal expansion of the liquid being absorbed by resilient expansion of the pipes between the master and slave cylinders.
