Title: A method of manufacturing helically finned tubes or rods
Inventor: SALLIS WILLIAM ARTHUR
IPC: B21C23/10
Filed: 1961-01-31
Abstract: 920,675. Making finned tubes, rods; twisting; extruding. CHESTERFIELD TUBE CO. Ltd. Jan. 5, 1962 [Jan. 31, 1961], No. 3581/61. Classes 83 (2) and 83 (4). A method of forming a helically finned tube or rod comprises forming a longitudinally finned billet, surrounding the surfaces with a complementarily shaped or composite body, drawing or extruding the body and billet assembly thus formed through a die having at least one helically extending rib whilst simultaneously retaining the undrawn portion of the assembly against angular movement so that the drawn or extruded portion of the assembly is twisted by the rib about its axis and subsequently removing the body. A core 5 is inserted into a hollow billet 3, e.g. of beryllium, having longitudinal extending external fins 4 which is inserted within an envelope 6 having internal complementary fins 7. Cylindrical end caps 8, 9 position the assembly within the envelope and are welded at their outer ends to the envelope and core. Prior to assembly the component parts are separated with lime or other suitable material to prevent welding together of the parts during drawing. The assembly is hot drawn or extruded through an internally ribbed die, the trailing end being held against angular movement whilst during the drawing operation the leading end is twisted by the ribs of the die to produce helical fins. After cooling, the assembly is broken down by pickling and mechanical means. The envelope may comprise a mild steel tube and separate fin forms 7 of e.g. chromium-nickel stainless steel. The die may have two stages to produce helical and straight fins.

Title: Improvements in recovering precious metals
IPC: C22B11/06
Filed: 1935-02-04
Abstract: Gold and other precious metals are extracted from pyritic ores &c. by calcining the ore and then treating it with a solution of hydrochloric acid and an alkali chlorate such as sodium chlorate in which ferric chloride is present.  Gold chloride is formed and goes into solution, and silver, when present, is dissolved by the sodium chloride resulting from decomposition of the chlorate. Solutions containing 2--5 per cent HCl and about 1--2\ba1/2\be per cent of chlorate may be used, whilst the ferric chloride content may initially be about 1 per cent, and is preferably formed by the action of the hydrochloric acid on the calcined ore.  By precipitating the gold from solution by means of iron, further ferric chloride is formed, and when using the solution cyclically, it becomes necessary to discard it when the ferric chloride content is too high.
Patent GB-783754-A (GB)
Title: Improvements relating to the production of amorphous silica
IPC: H05K3/20
Filed: 1956-02-06
Abstract: Amorphous silica is produced by passing a suspension of powdered silicon in pure oxygen through an externally heated tube at such a temperature and at such a rate of flow that the silicon is oxidized completely within the tube.  The tube is preferably heated to 1000-1350 DEG  C. and the residence time of the suspension in the tube is preferably 1.7-3.7 seconds (equivalent to an oxygen flow rate of approximately 2.5-5.5 l./min., using a tube of the dimensions specified in the example).  In the example a temperature of 1230-1240 DEG  C. and a residence time of 2.7 seconds is employed.  As shown, oxygen is passed through inlets 3 into a chamber 1 containing powdered silicon 4 <PICT:0783754/III/1> which is agitated by a stirrer 2, thereby producing a gaseous suspension of silicon which is passed through a ceramic tube 6.  A gaseous suspension of silica emerges from the tube, the silica being collected on a plate 10. Tube 6 is mounted in a fire-brick cavity heated by 4 vertical banks of gas burners 8 equally spaced around the cavity.

Title: Improvements in meat tenderers
IPC: A22C9/00
Filed: 1937-02-08
Abstract: 478,291. Making meat tender. JACKSON, A. L., DELEGARD, V., and FEDERAL ENGINEERING CO. Feb. 8, 1937, No. 3752. [Class 5 (i)] In a meat-tenderer of the kind comprising a series of disc knives mounted in spaced re. lationship on a common shaft, a spring stripper scraper assem. bly is provided having elements 34 extending between adjaceni knives and projecting towards the lower cutting edges to strip and guard the knives anc hold the portion of the meat adjacent each knife, each element having a free end to flex independently of the others. The device may be manually driven, but as shown, a motor C, in the base, drives the knives through a belt 22. The motor is mounted on a hinged bracket, the weight of the motor and bracket maintaining the tension of the belt. The spring elements 34 are held collectively on a bar 35 the ends of which are held in slots in bracket members 37 on the end walls 13, the hood B, when in position, preventing the withdrawal of the bar 35 from the slots. The meat is supported on a fibre feed plate F which co-operates with guides 26 so that it passes, in the direction of the arrow, beneath the knives. The guides 26 comprise guide rails joined by transverse members at their ends, and projecting through the bed-plate 14. The guides are attached to the plate 14 by screws which are adjustable to vary the height of the guides, and thus to regulate the depth of the cut. The hood B is held in position by screws 17 which serve to close oilholes 16 for lubricating the bearings of the shaft 15. The fingers 34 are of sufficient stiffness to restrain the entraining action of the knives on the meat and the board F, so that they move slower than the peripheral speed of the knives which thus act on the meat with a draw cut. The stripper assembly, when removed, may be used for cleaning the hubs of the knives.

Abstract: <PICT:0415046/IV/1> <PICT:0415046/IV/2> <PICT:0415046/IV/3> In apparatus for spinning artificial silk threads or filaments by the evaporative or dry spinning process having a spinning cell adapted to be heated and provided with an outlet having in association closing means adapted to render the said outlet substantially fluid-tight, the filaments pass from the spinning cell through the said outlet into a winding chamber in which they are wound.  A plurality of spinning cells 1 are built in pairs of batteries each of about 50 cells back to back with a platform 2 between each pair forming the ceiling of an enclosed alleyway between the rows of cells.  A winding chamber 3 provided with a partly glazed slidable counter-balanced door 5 adjoins the front of each spinning cell.  Rails 6 in these chambers above the winding mechanism 4 serve to store wound bobbins 7.  The filaments pass from the spinning cell through a substantially fluid-tight outlet to the winding chamber, so that as solvent-laden air is sucked from the spinning cell through the bee-hive shaped chamber 9 and piping 18 to the recovery plant, air from the winding chamber 3, entering at or near the base, and laden with solvent from the bobbins 7, passes via the pipe 8 through the unit 10 for heating the spinning cell, into the upper part of the spinning cell.  The substantially fluid-tight outlet for the spinning cell comprises a rectangular slot fitted with a rotatable bright metal rod 11 having circular end sections and a semi-cylindrical intermediate portion. The rod is loaded by a spring 12 so that the opening is normally closed as shown in Fig. 3, the filaments 17 passing through the small notch 16 in the packing plate 15.  A treadle 13 projecting at the base of the winding chamber 3 permits the closure member to be brought to the open portion shown in Fig. 2.
