Title: Improvements in or relating to the melt-spinning of synthetic linear polymers
Inventor: JONES DEWI MADOC
IPC: D01D4/00
Filed: 1964-06-03
Abstract: 1,079,295. Melt-spinning heads. IMPERIAL CHEMICAL INDUSTRIES Ltd. May 13, 1965 [June 3, 1964], No. 22887/64. Heading B5B. An apparatus for melt-spinning synthetic linear polymeric material comprises a meltspinning " head " containing a spinneret, a tubular heater positioned therein upstream of the spinneret, and means for distributing a stream of molten polymeric material supplied to the heater into a thinner stream or stream adapted to pass through the heater in that form. As depicted in the drawing (not shown), a part of the spinning head normally called the pack, but not containing a filtration medium as is the case in a normal pack, comprises a spinneret plate 1 held tightly in place at the bottom of the pack by retaining ring 3 and its accessories as in conventional meltspinning packs. The pack is screwed into a cavity within the melt block from which it is supplied with molten polymer. Aluminium distributer body 15 within the central channel 21 of tubular heater 13 spreads the oncoming stream of molten polymer into a thin stream of annular cross-section. The heater is electrically heated by means of current supplied by leads 23. The " cooler " 17 of the pack consists of an aluminium block with a number of ducts 25 bored through it and fills the space normally occupied by the filtration medium. Electric heater coils 27 maintain the pack at the desired extrusion temperature, the function of the cooler being to reduce the temperature of the melt from the high temperature to which it has been quickly " flash " heated in the tubular heater back to the normal temperature for extrusion. The melt issuing from the bottom of the cooler 17 flows through the screen 11 and enters the holes of the spinneret plate 1. The means for distributing the stream of melt may comprise a distributer plate containing holes adapted to form the oncoming stream into a number of thinner streams.

Title: Improvements in or relating to forging machines,particularly die-forging machines
IPC: B21J7/14
Filed: 1965-05-31
Abstract: 1,060,915. Power hammers. GESELLSCHAFT FUR FERTIGUNGSTECHNIK UND MASCHINENBAU G.m.b.H. May 31, 1965 [July 10, 1964], No. 22973/65. Heading B3H. A die forging machine includes a pair of opposed hammers 1 which are forced together by means of a common pneumatically operated driving piston 6, and which are urged apart hydraulically. To initiate forging, a solenoid operated valve 26 is actuated to cause a slide valve 26 to move to the left. Fluid from a supply pipe 23a is then directed along conduits 23 and 22 to move a spring-biased pilot valve 16 to the right. This blocks a supply conduit 18 to chambers 12 and 14, and connects the chambers with conduits 13 and 15 leading to piston-cylinder assemblies 2, 3 for the hammers. The driving piston 6 is forced by compressed nitrogen to the left, thus causing its faces 8 and 9 of equal area to force fluid into the piston cylinder assemblies 2, 3 to produce forging. A pilot valve 24 is simultaneously moved to the left to interrupt the conduits 22 and 23 and allow the pilot valve to be spring returned to its initial position. The piston cylinder assemblies are exhausted through conduits 13, 15 and 19, to allow hydraulic fluid in reservoirs 5 to urge the hammers to their starting position. It is possible to provide more than one pair of opposed hammers.
Patent GB-533511-A (GB)
Title: Improvements in or relating to missiles, especially hand grenades
IPC: F42C15/22
Filed: 1939-08-09
Abstract: 533,511. Ammunition. HAUG, R. Aug. 9, 1939, No. 23009. Convention date, Aug. 28, 1938. [Class 9 (i)]  A hand-grenade comprises two parts which are relatively moved to compress the loading- spring of the firing-pin, means for holding the spring compressed with the pin safe, and a centrifugally-actuated catch to permit advance of the pin by further relative displacement of the parts on impact. As shown, the chargecontaining body 1 is fitted with a sleeve 15 housing the cartridge 16, the firing-pin 7 and its loading-spring 8. The latter is housed between the sleeve 15 and a sleeve 4 having a flanged head 20 normally seated on a flange 24 of a handle member 3 which is movably fitted in a fixed cup 2 closing the upper end of the body 1. The sleeve 4 is formed with a cage 21 for a series of balls 9 which normally occupy the position shown in Fig. 1, but move into a groove 19 in the cup 2 when the handle 3 is pulled, as seen in Fig. 4. A cap 5, having a friction-fit in the sleeve 4, is normally secured by means of an arm 23 projecting from a weight 12 which is held against the handle 3 by means of a resilient strip 14 secured at 29 to the casing 1. The strip 14 has tongues 27 normally engaging slots 28 in the handle, but drawn clear when the latter is pulled away from the casing, thereby also freeing the weight 12. If now the grenade is given a spinning throw the arm 23 is pulled away from the cap 5 owing to the centrifugal action of the weight 12 and on the least shaking the parts 1, 3 become axially displaced, as seen in Fig. 2. The result of this is to free a coiled spring 11, which normally tends to assume a straight-line form. from its housing under the flange 20, the latter then being brought into edge-contact with a tensioned plate-spring 13 bearing on the coned top of the cap 5. On impact of the grenade, the spring 13 forces the cap 5 along a sleeve 6 surrounding the pin 7 thereby freeing a locking-ball 10. The reaction of the spring 8 then forces the firing-pin on to the ignition-cap 17.

Abstract: <PICT:1098622/C4-C5/1> An annular ceramic core is externally coated and uniformly impregnated with Ni, Pd or Pt catalyst and has external lands 15 for spacing it within a reactor tube.  The core may be a permeable moulding of MgCO3 and "Britmag" (Registered Trade Mark) which is first impregnated with Ni(NO3)2 solution then fired at 550 DEG  C. to reduce to metallic nickel. Alternatively a layer of catalyst is secured by keying or by adhesive to the core.  The external surface of the core may be helically ribbed.  In use, a series of cores are piled in a vertical heated tube, lands 15 centralizing the cores to form an annular passage between cores and tube (Fig. 4, not shown).  A central locating tube is threaded through the cylindrical passages 32 of the cores, annular grooves 33 containing sealing rings. Steam and vaporized light hydrocarbons pass down or up the annular passage, lands 15 giving them a helical motion, and town gas is thereby obtained.  The feed gases may enter the passage at the top and be returned up the central tube to an adjacent outlet, e.g. as described in Specification No. 1,036,447. Figs. 1, 2 (not shown) illustrate a core having a conical mouth at one end which receives a sealing ring to seal it to the central tube.

Title: Improvements relating to processes and apparatus for the reaction of solid substances with gases
IPC: C22B1/10
Filed: 1952-09-16
Abstract: <PICT:0763048/III/1> <PICT:0763048/III/2> <PICT:0763048/III/3> A process of reaction of a solid material with a gas in a swirling reaction mixture with production of heat, is applied to the roasting of sulphide ore in a furnace 2, in which powdered ore is fed by a shoot 5 in counter-current to air supplied with a whirling motion through a conical grate 7, and in which heat from the reaction zone 1 is radiated in a regulated manner from a protective wall 9 to coiled tubes 10 forming part of a boiler circuit.  The radiant heat absorbed may be controlled by movements of a slotted screen 15, Fig. 3, between the wall 9 and the coils 10.  Alternatively, the number of coils 10 directly exposed to the wall 9 may be varied, Fig. 4, by movement thereof behind a lower shielding wall 16, advantage being taken of the elasticity of the coils.  Further tubes 8, also in the boiler circuit, may be disposed in the upper part of the furnace. Air is supplied to a plenum chamber 11 through a pipe 12 under pressure so that in the event of a failure of the wall 9, the tubes 10 are not subject to the action of extremely hot, corrosive gases. A tangentially disposed offtake 13 leads the gases through a cyclone separator to a further heating surface of the boiler.  In a modification (Fig. 2, not shown) the conical grate is replaced by horizontal water-cooled grate bars, and the whole of the furnace chamber is cooled by the protective wall 9.

Title: Analysis of gases
IPC: G01N30/86
Filed: 1956-07-27
Abstract: The process of the parent Specification for determining the concentration of a particular component in a mixture of gases and/or vapours is modified by separating the mixture chromatographically into various fractions and passing these successively into the detector.  In the Figure the gas mixture enters at 103 and passes through the column 105 which contains a substance (e.g. alumina, silica gel) capable of adsorbing all the components of the mixture. The column is held at a constant temperature by a heater coil 106 and regulator 108 operated by the thermocouple 110.  The twin detector cells 124, 125 (containing e.g. activated carbon) are fed alternately from the column output 111 and a compressed air supply 116 via the change-over <PICT:0811744/III/1> valves 112, 115, the air being also passed through the column via the pipe 101 to elute the gaseous components in succession.  The cyclic changes in temperature in the detector cells due to adsorption and desorption are sensed by the thermopiles 126, 127 and displayed on the chart 130.  As the pen 132 moves, the pawl and ratchet 135 is operated by the weight 138 so that the potentiometer 133 transmits to the remote indicator 141 an integrated reading of the constituents of the mixture.  This potentiometer can be reset to zero by automatic means (not shown), e.g. a programme timer.  The signals from the thermopiles can be used to actuate process controls to maintain the composition of any particular component in a flow stream.  Particular applications of the system are for mixtures of (a) ethane, propane, propylene and butane, and (b) ethylene and a small amount of propylene.

Title: Apparatus for determining the dust content of gases or vapours
IPC: G01N27/60
Filed: 1959-07-07
Abstract: 901,033. Determining analysis of mixture by electric tests. FEIFEL, E., and PROCHAZKA, R. July 7,1959 [July 19, 1958], No. 23308/59. Class 37. Apparatus for determining the dust content of gases or vapours comprises a tube through which the mixture flows in a helical path, the tube being provided with an outer shell for shielding it against external disturbances. A charge is imparted to the tube and this is measured by a current measuring instrument through which a discharge takes place to ground and is proportional to the concentration of dust particles present in the gas or vapour. A guide electrode having one or more guide passages is arranged before the tube so that the mixture is caused to flow mainly in planes normal to the axis of the tube. The Figures show an apparatus through which a stream of gas or vapour 1 in which is suspended particles of dust passes through a zone 7 which imparts to the mixture a radial and a tangential component of flow. The mixture passes inwardly through tangential guide passages 15 so that it flows through the tube 4 with a twist from which the dust particles are urged by centrifugal force to the tube wall. The tube 4 is mounted via insulation at 8 and 9 on to a housing 12 so that the wall of the tube 4 acquires a charge which provides a measure of the dust content of the gas which is indicated by a current measuring instrument 11 connected between the wall 4 and earth. The tube 4 is protected against external mechanical, thermal and electrical disturbances by a protective shell 5 and a jacket space 6 which is filled with gas. The diameter of the housing 12 is not larger than but preferably as large as the diameter of the shell 5 and the diameter of the housing of the guide device is equal to or smaller than that of the shell 5. The gas-dust mixture 1 may enter the housing 12 in other than the axial direction for example in a plane normal to the axis.
