Title: Improvements in and relating to glass fabrication
IPC: C03B23/055
Filed: 1945-03-16
Abstract: 600,667. Glass. MacGREGOR INSTRUMENT CO. March 16, 1945, No. 6694. Convention date, Dec. 10, 1941. [Class 56] Relates to apparatus for accurately sizing, without grinding, the coacting surfaces of two glass members working one within the other, e.g. the piston and barrel of a hypodermic syringe, the rotary valve and stationary shell of a stop cock, bearings and injection nozzles for Diesel engines. As shown applied to the making of a hypodermic syringe, a length of glass tubing 32, Fig. 7, longer than the finished barrel is placed over an arbor 34, the diameter of which corresponds exactly to the required internal diameter of the barrel and, after the blank has been subjected to a preliminary heating, the lower end is constantly pressed into engagement with a shoulder 35 on the arbor by means of a weighted plunger 43. Reciprocating burners 42 positioned between three rollers 39 now traverse the blank and the rollers 39 and arbor 34 'are rotated in opposite directions. A flange 22 is formed at one end of the barrel by means of annular grooves 39<SP>1</SP> in the rollers 39 and is slabbed off at opposite edges by cutters and a perforated nose is formed at the other end by rollers, not shown. The plunger is formed somewhat similarly by the three rollers 61 and heaters 72 shown in Fig. 11. The rollers 61, which are rotated about axes at predetermined distances apart, are so shaped at one end that, acting in conjunction with an adjustable stop 68 into contact with which one end of the blank 33 supported by an arbor 60 is constantly pressed by a pressure tube 77 1  which moves from right to left, the plunger head 29 is formed. The forward end of the plunger is cut off to the required length and closed by a flame.

Patent GB-803026-A (GB)
Title: Plant for a gaseous reaction process
IPC: F22B1/16
Filed: 1956-03-06
Abstract: <PICT:0803026/III/1> <PICT:0803026/III/2> In a gaseous reaction plant hot-pressurized waste gases are used to compress incoming process gases entering inlet 2 by means of a pressure exchanger 1, the compressed gas together with gas from an inlet duct 8 passing to an exothermic reaction chamber 7.  The resulting mixture is passed to a separator 11 which removes the product gas and returns the waste gases to the pressure exchanger via a heat exchanger 9 and duct 14. The pressure exchanger 1, Fig. 1, has transfer passages 1A and an inlet duct 2 leading to a rotary member with cells 3 in which the process gas is carried in the direction of the arrow 4 until the process gas is compressed by waste gases received from the duct 14, the compressed gas then passes by duct 6 to the reaction chamber 7. An exothermic reaction takes place in the reaction chamber in the presence of a suitable catalyst and the waste and product gases may pass through a heat exchanger 9, a cooler 10 and the separator 11. The waste gases on returning are reheated by passing through the hot pass of the heat exchanger 9 and are exhausted, at low pressure, through duct 15.  For the preparation of nitric acid from air and ammonia entering inlets 2 and 8 respectively the nitric oxide formed in the reaction chamber 7 is absorbed in the separator 11 by water from inlet 12 to give a nitric acid solution which leaves by outlet 13.  In a modification, Fig. 2, the waste gases do not pass through the heat exchanger on leaving the separator 11.  Instead, the waste gases are mixed in a combustion chamber 16 with a fuel from an inlet 17 and burnt with air from duct 18 lead off from the main air supply duct 6 before entering the pressure exchanger 1 by duct 14.

Abstract: 1508273 Partially reduced iron oxide; hydrogen sulphide; sulphur STORA KOPPARBERGS BERGSLAGS AB 24 Feb 1976 [3 March 1975] 7313/76 Heading C1A [Also in Division C7] Fine-grained iron oxide-containing material is continuously partially reduced by contact in a fluidized bed at 800-1200C. with a sulphurcontaining solid (and possibly also a liquid) carbonaceous material in the presence of a finegrained sulphur-binding material containing CaO and/or CaCO 3 . The bed is fluidized by reducing gas and the iron oxide material is introduced into limited zones around the inlets for the carbonaceous material while the sulphur-binding agent is supplied outside those zones. The discharged product is cooled to below the Curie point of iron and then subjected to magnetic separation; the magnetic fraction may be smelted to crude iron and the non-magnetic fraction treated for sulphur removal and then recycled. As particularly described bed I is supplied with inputs of iron oxide material 3; carbonaceous material 2 and CaO/- CaCO 3  4. The discharge passes to cooler 8 and magnetic separator 9, the non-magnetic fraction passing to fluidized bed 12 where it is reacted at 500-750C. and 5-20 atmospheres with a gas containing H 2 O and CO 2 . The desulphurized solid discharge returns to the reduction bed, and the gas stream containing H 2 S passes through cooler 14 to a Claus reactor 18 for sulphur recovery.

Abstract: 1,081,201. Multi-screw extrusion machines. J. BLOMET, and G. COINDREAU. Feb. 22 1965 [Feb. 24, 1964; Dot. 28, 1964], No. 7576/65. Heading B5A. In a multi-screw extrusion moulding machine, pasty material is fed from a hopper 1 to a horizontal bank of screws 5, wherein adjacent screws rotate in opposite directions and have flights of opposite pitch, the pitch decreasing in the downstream direction, and the material is initially prevented from rotating with the screws by a drum 6 carrying vanes 8, 9, the vanes co-operating with flights 11 to cause rotation of the drum. A compression chamber 13 downstream of the drum is formed by a sleeve 14 of nylon or polyethylene and coaxially of each screw is mounted an extrusion nozzle 16 which is releasably held in position by a lever 19, pivoted about a removable pin 20 and bearing against part of the nozzle, and a lever 22, pivoted on a rod 24 and carried by a member 25. Member 25 is rotatable about an axis 26 by means of a lever 27, and on removal of pin 20 and movement of lever 27 to the left, the nozzle may be displaced to facilitate cleaning. The extrusion passageway of each nozzle 16 may be varied in size by a rod 35 having a cutaway portion 36, the rod being rotatable into and out of the stream by a lever system 37, 38, 42 actuated via an axle 43. Each screw 5 may be removed subsequent to the removal of a bushing 30, common to all the screws or provided for each, normally held in position by screws 31, 32. A device to prevent extrusion due to the expansion of trapped gases, after termination of operation of the corresponding screw, comprises a piston (48), Fig. 4 (not shown), whose end (47) is held flush with the internal surface of barrel (1) by compressed air, which enters cylinder (45) via conduit (51), until the screw is stopped, whereupon the air supply is simultaneously cut-off and the piston is allowed to rise to reduce the extrusion pressure.

Title: Method of making porous paste carriers for use in alkaline storage batteries
IPC: H01M4/80
Filed: 1961-03-02
Abstract: A porous electrode, which may be charged with an active paste for use in alkaline accumulators, is made by coating a granular conductive or non-conductive material with a heavy electro-deposit of metal, e.g. Ni, Co, or Cd, so that the granules are formed into a rigid porous structure.  Granules of Fe, Ni or carbon of uniform size are poured into a supporting structure of sheet or perforated metal, loosely compacted steel wool, ribbons or strands, and forms the cathode placed below an anode in the plating bath.  The cathode may be magnetic to keep the particles from floating, or these may be pressed into position mechanically, or by centrifugal force.  Preferably the granules are first soaked in a metal salt solution drawn into the body of granules before electrolytic deposition from the solution, and the granules may be pre-coated with copper.  The rigid porous structure may then receive a further metal coating by applying nickel carbonyl in vapour, liquid, or dissolved form, and subsequently heating to decompose the carbonyl, and deposit nickel on the electrode, which may then be firmly bonded by sintering.
