Patent GB-475711-A (GB)
Title: Process of and apparatus for the continuous deacidification and after-treatment of artificial fibres in endless form
IPC: D01D10/04
Filed: 1937-01-19
Abstract: <PICT:0475711/IV/1> <PICT:0475711/IV/2> A band of artificial fibres is subjected to treatment with water, saline solutions, or other liquids, or with vapours continuously with production, immediately after issuing from the spinning machine or after an intermediate treatment, while passing in substantially vertical convolutions around a series of guide rollers located in a treatment chamber and under a constantly changing tension, without slipping over the rollers.  The action of the treatment liquids or vapours may be assisted by alternately squeezing the fibre band and allowing it to swell again.  This action may be intensified by a short vertical reciprocating motion or other oscillating motion of the band, which is allowed to shrink without friction or resistance by reducing the distance between the guide roller.  The washing, de-acidifying, and other liquid or vapour treatments may be carried out at temperatures near the boiling point of water.  The process is particularly applicable to the production of viscose artificial fibres.  As shown in Figs. 1 and 2, a treatment bath 1, preferably of aluminium lagged on the exterior surfaces with heat insulating material, is sub-divided by partitions 2 into a number of separate compartments. The fibre band is guided by rollers 4, 41, by means of which it passes in vertical convolutions through the various treatment fluids. Rollers 4 are mounted on frames 5 to which there is imparted a reciprocating motion by a cam-shaft.  The rollers 41 are mounted in frames 51 which may be lifted out of the bath when introducing the fibre band.  Frames 51 may be coupled to frames 5 so that the oscillating motion may also be imparted to rollers 41.  The distance between rollers 4, 41 diminishes progressively in the direction of travel of the fibre band so as to allow the band to shrink without resistance.  The alternating stressed and unstressed condition of the band may be effected by employing guide rollers 6 of elliptical shape, or by reducing and increasing in rhythmic fashion the distance between rollers 4, 4<1>, as by mounting them eccentrically or by using cam mechanism.  For starting the operation, the frames 5<1> are lifted, and the upper members of the pairs of squeezing rollers 3 are removed. The fibre band is led from the spinning machine over the whole length of the apparatus.  Frames 5<1> with rollers 4<1> are then lowered into the bath, and the squeezing rollers 3 are replaced. The material issuing from the treatment apparatus may be cut to staple length or dried in band form.

Title: Hydraulic control for machine tools
IPC: B23Q35/18
Filed: 1951-01-22
Abstract: 687,533. Copying lathes. FISCHER AKT.- GES., G. Jan. 22, 1951 [Jan. 20, 1950], No. 1633/51. Class 83 (iii). In a hydraulic control for lathes and other machine-tools, a feeler lever 34, co-operating with a template 9 on the machine base, controls the pressure of a constantly-flowing pressure medium on one side of a differential piston 17 while the pressure on the opposite side of the piston is kept constant by an overflow valve 42, the latter valve being inoperative when the hydraulic control is first set in operation. The control is described as applied to a hydraulic copying lathe comprising a saddle 2 carrying a tool-slide 3 which can be fed by a hand wheel 14 actuating a screw 15 engaging a nut 6. The screw 15 is splined at 16 so that sliding movement may take place during automatic operation under the control of the feeler 34 and the templet 9 supported on arms 7. The screw 15 is connected to the piston 17 which is formed with an internal passage 22 leading to the valve 20 and thence to an exhaust line 29. The opposite side of the valve 20 is connected to atmosphere through an adjustable needle valve 27. The valve 20 is urged against the feelerlever 34 by a spring 21. The lever 34 abuts, at one end, an adjustable limiting screw 33 and, at the other end, either an adjustable cam-rod 36 or the templet 9. The cylinder 56, containing the piston 17 has an adjustable air outlet 40. If the lathe is to be used for ordinary turning, the piston 17 is locked, the rod 36 is moved to the right and the templet 9 is removed. For hydraulic operation, the slide 3 is first set by the hand wheel 14. The pump 53 is then set in operation, the screw 33 being set so that the valve 20 permits a slight rise in pressure in the cylinder 56. When the air has been exhausted through the outlet 40, a momentary closing of the valve 20 by movement of the rod 36 to the left causes a rise in pressure in the system sufficient to move the valve 42, Figs. 2 and 3, to the right. Fluid then passes to both sides of the piston 17 and the rod 36 is moved to the right to allow the feeler 34 to contact the templet 9. The valve-spring 44 and the valve 20 then act to maintain equilibrium in the system while the copying action progresses. For cylindrical turning, the rod 36 may be set to contact the cam 37 at the required depth. If the piston 17 should reach its righthand limit, or the rod 36 not be released, so that an excess rise in pressure occurs, the valve 42 is moved further to the right and pressure fluid is exhausted through a line 52. The valve 42 may be replaced by a modified type of valve or its two functions may be performed by separate valves 63, 72, Fig. 7. Specification 597,017 is referred to.

Title: Improvements relating to the production of low temperatures
IPC: F25B9/06
Filed: 1934-01-18
Abstract: 433,860. Actuating pumps. KAPITZA, P., Royal Society Mond Laboratory, Free School Lane, Cambridge. Jan. 18, 1934, No. 1814. [Class 102 (i)] [See also Group XXVI] In piston and cylinder apparatus for producing very low temperatures such as those required for the liquefaction of air, hydrogen, neon, helium, &c. by expansion of the compressed gas with recovery of external work, the piston 2 is connected by a rod 3 with a piston 5 working in a cylinder 4 which is supplied with water through a connection 37 provided with a non-return valve. When the valve 39 is opened by an external source of power, water is forced through a hole 9 and outlet 38 by the upstroke of the piston 5 occasioned by the expansion of the gas. This may be used to pump the cooling water for the compressor em ployed to compress and circu late the gas.
Patent GB-450684-A (GB)
Title: Improvements in or relating to the manufacture of ethylidene diacetate and homologous esters
Filed: 1935-01-19
Abstract: Alkylidene diesters substantially free from vinyl and homologous esters are prepared by reaction in the vapour phase of a hydrocarbon of the acetylene series and an aliphatic acid, the proportion of the latter being in excess of two molecules per molecule of hydrocarbon, e.g. 3--4 or 5--6 molecules.  Acetic acid vapour and acetylene may be passed through a tube containing filling materials and catalysts at, e.g. 150--300 DEG  C., suitably 180--250 DEG  C., and the reactants may be preheated.  Pressure is preferably atmospheric or above but may be reduced.  Catalysts include oxides or salts, e.g. acetates or carbonates, of zinc, nickel, iron or cadmium.  These may be used in conjunction with, e.g. pumice, kieselguhr, activated charcoal or silica gel. Diluents such as inert gases, e.g. hydrogen, carbon dioxide or methane, or acetic anhydride vapour, may be present. Acetylene and propionic acid give ethylidene dipropionate, while employment of allylene instead of acetylene yields propylidene diesters.  In an example, a mixture in the proportions of about 4 mols. acetic acid vapour to 1 mol. acetylene is passed through a tube containing pumice and zinc acetate at 210--215 DEG  C.  The reaction products are condensed, ethylidene diacetate being separated from unchanged acetic acid by fractional distillation or condensation.

Title: Improvements in cash boxes for coin freed apparatus
IPC: G07F9/06
Filed: 1945-01-24
Abstract: 612,710. Coin-freed apparatus. H. T. A., Ltd., and HALL, F. W. Jan. 24, 1945, No. 1910. [Class 27] Money-boxes.-A removable cash box for a prepayment telephone, or other coinfreed apparatus, has a shutter for closing the aperture by which the coins enter the box, and the coin-freed apparatus has a projecting pin which operates the shutter positively, by cam action, to open it when the box is introduced into the apparatus and to close it again when the box is removed. On the underside (Fig. 3) of the removable lid G of the box is a shutter J pivoted at J<1> for closing the coin aperture H. A latch K, pivoted at K' and biassed clockwise by a spring K<2>, engages with a pin O on the shutter to hold it closed. When the box is introduced into the coin-freed apparatus, a pin E projecting down from the roof of the coin box compartment enters a slot F in the lid G and thrusts aside the latch K to release the shutter J which is then positively opened by a projection E<1> on the pin working down a cam slot L' in a plate L secured to the shutter. Closure of the shutter is likewise positively effected when the box is withdrawn, the parts then being as shown in Fig. 3 with the latch K back in locking engagement with the pin O on the shutter. To prevent interference by the collector with the latch K through the slot F, the latch K is then itself locked by an inaccessible pivoted catch N. A spring N<3> snaps the catch N into its two end positions. It is moved clear of the latch K when the lid is unlocked and removed by a person authorised to empty the box, this being effected by a heel N' of the catch abutting a ledge on the side of the box. When the box is inserted in the apparatus a pin K<3> on the shutter, as it opens, knocks the catch back ready to snap behind the latch K when the box is withdrawn.

The door is ordinarily opened by pulling handle 50 to rotate shaft 44 and so release the bolts on its ends from the keepers 30. When closed the handle 50 is held by retainer 52.  In an emergency the door may be opened from the other side by means of a mechanism (see Fig. 3) which detaches retainer 52 from the door, forcing it outwards and so pushing the handle 50 thus unfastening the door. This mechanism comprises a back plate 64 of the retainer which has an internally threaded hub 70 projecting into the door. This hub 70 engages a threaded end portion 82 of a shank 78 to the other end of which, on the inside of the door, is attached the emergency release handle 80. The shank 78 is secured against longitudinal movement by means of a strap 90 which is fixed to the door and engages an annular groove 88 in the shank 78. Rotation of the handle 80 thus forces hub 70 out of the door which is thus unlocked. Light may be admitted to the interior of the container sealed by the door by means 94 comprising a plastics rod running the breadth of the door and terminating near the emergency handle 80 to guide a trapped person to it. The inside face of the rod may be shaped into an arrow to indicate the direction in which the handle is to be turned.
