Title: Improvements in or relating to the production of crepe-like textile fabrics
IPC: A61F11/08
Filed: 1937-04-26
Abstract: In the production of cr<\>zepe-like textile fabrics, a fabric comprising shrinkable threads or thread parts of untreated cellulose acetate silk, and unshrinkable threads or thread parts either of cellulose acetate silk protected by treatment with a reserve or of relatively non-shrinkable threads of another kind, is treated with hydrochloric acid of 23-26 per cent as shrinking agent.  The threads are preferably not or only slightly twisted. Suitable reserves are phenols, tannin or catechol, e.g. in aqueous solution with a small quantity of swelling agent for the cellulose acetate such as formic acid, or sulphonated water-soluble synthetic resins, e.g. phenol-aldehyde resins, e.g. as emulsions or suspensions.  Natural or synthetic resins, waxes, or paraffins, e.g. a solution of colophony in xylene may also be used.  The thread or fabric treated with the reserve may be steamed to ensure fixing.  Threads treated thus may be suitably dressed, and if desired dyed for identification before weaving with an untreated thread.  Preferably the fabric contains 5-10 unshrinkable threads for about 3-8 shrinkable threads. Treatment of threads with the reserve may be effected by dipping hanks partially or wholly into the reserve.  Fabrics may be immersed in a bath or printed, e.g. locally with the reserve.  Shrinkage is preferably effected at 18-20 DEG  C., and may be 10-50 per cent. p The reserves may be removed with alkali or soap lye when neutralizing after shrinkage.  Drying of piece goods is effected in loose condition on formers tables or moving belts.  Stretching is to be avoided.  Threads may be incompletely protected against shrinkage in parts and the degree of protection may vary in different parts of the thread.  In place of some or all of the protected acetate threads, threads of silk, wool, cotton, linen, or cellulose artificial silk may be used.  A variety of effects such as cloqu<\>ae, fa<\>cconnet or the like may be produced by suitable combinations of treated and untreated threads in the fabric.  Shrinkable and unshrinkable threads may be twisted together to make fabrics showing cracknel effects. Mixed fabrics of shrinkable and non-shrinkable threads may be printed locally with a reserve before shrinking.  Specification 413,150, (as open to inspection under Sect. 91), is referred to.

Abstract: 1353514 Boots &c BRITISH UNITED SHOE MACHINERY CO Ltd 29 April 1971 [30 April 1970] 12046/71 Addition to 1235096 Heading A3B The lasting machine of the parent Specification which includes wipers which are temporarily arrested when they contact the upper so that an insole plate can be lowered out of the path of the wipers, is modified by including means to vary the positions taken up by the leading edges of the wipers in their temporarily arrested position to suit them to shoes of different sizes, comprising means for detecting the length of the shoe, and means assocaited with the length detecting means for regulating the means for temporarily arresting the wipers. As described the wipers 99 are arrested by a wedge shaped abutment 113 which is moved by piston and cylinder device 116 from a retracted position into the path of a stop member 117 on the piston rod 118 of the wiper operating means. The operative position of the wedge 113 is determined by a stop formed by a piston rod 112 connected to a piston 110 in cylinder 109. In a first embodiment as shown the cylinder 109 is connected by pipe 141 to a cylinder 105 which moves the heel rest 103 into contact with the shoe 101. The spaces 107, 111 in the cylinders 105, 109 and the pipe 141 are filled with hydraulic fluid so that the stop 112 is moved a distance proportionate to the distance moved by the heel rest 103. Movement of the stop 112 varies the operative position of the wedge 113 and thus varies the arrested position of the wipers. In a modification (not shown) the cylinder 109 is controlled by a solenoid operated valve which is actuated by switch which is opened and closed by cam carried by the heel rest. For shoes in a large size range the switch remains open and the stop 112 occupies a retracted position, and for shoes in a small size range the cam closes the switch so that the stop occupies an extended position.

Title: Automatic needle supplying and changing attachments to gramophone and like machines
IPC: G11B3/46
Filed: 1928-04-26
Abstract: 291,349. Triggs, W. W., (Mangham's Automatic Needle Changer, Ltd.). April 26. 1928. [A Specification was laid open a to inspection under Sect. 91 of the Acts, June 1, 1928]. Supplying tools from magazines.-Relates to automatic needle changing devices. During outward movement of the tone arm the needle gripper is released b a lever coming against a fixed cam surface, and as the movement is completed a transfer plate is operated to deliver a fresh needle to the holder in which it is positiond by an adjustable form below. The needle is normally gripped on the socket 3, Figs. 1 and 4, by the wedge-shaped side 4a of a spring-pressed pin 4 slidable in the needle holder 1. When the tone arm is returned after playing, the part 7<b> of a lever 7 pivoted at 7<a> to a bracket 11 on the sound box is carried along a fixed cam surface 8, Fig. 5, whereby the lever 7 is rocked and allows the spring 6, Fig. 4, to slide the pin 4 and release the needle, which falls through the socket 3. As the tone arm completes its movement, the bracket 11 rides between fixed guides 12, 12<a> and acts on a lug 28 to rock a pivoted quadrant 21 having a. slot 23 to which a fresh needle is fed, and the needle is then carried to the vertical positions and falls through a slot in the pivot boss 30 of the quadrant and into the socket of the needle holder which is now immediately below.. The needle thus supplied is supported by a pivoted platform 13 below, which is grooved as shown at 16<a>, Fig. 6, to avoid damage to the point. As the tone arm is returned to starting position the lever 7 passes clear of the cam 8 and permits the spring 6 to move the pin 4 to grip the needle, and the needle point is carried out of the end of the groove of The pivoted platform 13, which can then be returned to normal position by the spring 14. The needles are supplied to the slotted quadrant 21, Figs. 1 and 7, from a magazine 17 which can be filled in the factory and has detachable engagement by flanges 18<a> with one wall 19 of the fixture within which the quadrant rocks, such wall having a channel 20 in continuation of the magazine so that, the needles can pass singly to the channel in the quadrant. A spring 24 effects return movement of the quadrant, and the passage of the needles thereto is facilitated by the sharp knock given by the spring-returned platform 13 to a projection 15 from the wall 19.

Filed: 1926-05-12
Abstract: 275,728. Automatic Telephone Manufacturing Co., Ltd., and Adams, H. May 12, 1926. Contact-making relays.- A two-step relay has the winding for effecting the partial operation mounted on a portion of the core of small cross-section as compared with the core surrounded by the winding for effecting the full operation so that a considerable increase in the current through the first winding will not appreciably increase the pull on the armature. As shown in the Figure the winding 3 for effecting partial operation of the armature 5 is wound on a portion of the core 2 of smaller diameter than that surrounded by the main winding 4 so that the constricted portion is normally approaching saturation and variations of the applied voltage make little difference on the pull of the armature. The constricted portion of the core may be formed by turning down a portion of a standard core iron. The relay may be used to operate as a marginal relay over junction telephone lines and the second winding may be energized by operation of x springs by the partial attraction of the armature.

An apparatus for heating material comprising a heating zone having a material inlet and outlet and a temperature control arrangement responsive to the temperature of the material in the zone and regulating the amount of heat supplied has also a means responsive to a temperature of the material leaving the outlet which through the control means modifies the amount of heat supplied to the heating zone. The temperature of a gas or oil fired glass melting furnace is sensed and controlled by thermocouples 20, the glass flowing outwardly through one or more exits 17 in the lower or upper part of which is another thermocouple 50, the signal from which is received at an amplifier 52. A signal, reducing with time, from thermocouple 50 indicates a slowing down of glass "draw off" hence this signal, below a determined level, is passed through a computer 54 to reduce the furnace heating. The signal may be sampled say every two seconds by the computer 54, or alternatively or additionally by an integrator 56 which may be used to measure the rate of change of temperature, and rates of change outside a determined band are not passed forward to the furnace controller hence the temperature is maintained at its previous level. The circuit may be arranged to discriminate between cooling caused by shut down, and temperature reductions caused by islands of incompletely melted material. The arrangement may be used in an oven for processing heat cured binder in the production of mats.
