Title: Improvements in the extrusion of tubular products
Inventor: FENTIMAN DENIS RICHARD
IPC: B21C23/21
Filed: 1966-01-25
Abstract: 1,112,322. Extruding; billet piercing. BALDWIN - LIMA -HAMILTON CORPORATION. 25 Jan., 1966, No. 3345/66. Headings B3H and B3P. A tubular product is formed by extruding a billet 78 between a mandrel 50 and die orifice 82 and after extrusion the discard 94, Fig. 5 (not shown), is sheared off by a shearing sleeve 54 surrounding the mandrel. The billets 78 and a dummy block 74 are fed by a loader 76 into alignment with the container bore 36 and pressed therein by the press stem 68 actuated by the main hydraulic ram 16. The latter carries an inner cylinder 26 for the double-acting mandrel-actuating piston 40 which is pressurized through duct 44 to pierce the billet, Fig. 2 (not shown). Forward movement of the mandrel in its cylinder is limited by a snap-ring 39. Shearing sleeve 54 fits within dummy block 74 and is actuated by double-acting plunger 52 working in cylinder space 56. Movement of this plunger in both directions is limited by a stop 62 and a shoulder 60. A method of operation is described for extruding open-ended tubes and hollow products with one or both ends closed.

Title: Improvements in and relating to Metal Drawing Dies.
IPC: B21C3/12
Filed: 1917-03-07
Abstract: 113,830. British Thomson - Houston Co., (General Electric Co.). March 7, 1917. Drawings to Specification. Alloys; dry processes of extracting tungsten.- Wire-drawing dies are made of an alloy of iron and tungsten containing between 5 and 15 per cent of iron. The dies are formed from powdered tungsten obtained by reducing tungsten oxide which is arranged in a refractory tube through which dry hydrogen is passed, the temperature being raised to 900 or 1100‹ C. in six or seven hours. The alloy is obtained by dissolving about 500 grammes of ferrous sulphate in about four litres of water and adding ammonia slowly to precipitate ferrous hydrate. The washed precipitate is poured into an evaporating dish, containing 900 grammes of powdered tungsten and after mixing the contents are dried and then placed in sheet iron boats in charges of about 300 grammes each and reduced in dried hydrogen in an electric furnace. The powder after sifting is pressed into disks which are placed in a boat or on a strip of material such as molybdenum and introduced into an electric furnace comprising a tube of porcelain or alundum heated to about 1800‹ C. in an atmosphere of hydrogen for about half an hour.

Abstract: 113,833. Middleton, H. March 8, 1917. Steering. - An aerial vessel is steered or manoeuvred by a steering screw propeller with fixed or adjustable blades rotating on a transverse axis either at the bow or stern of the vessel, with or without the addition of a pair of oppositely rotating screw propellers rotating on an axis capable of being inclined in any direction. The axis of the oppositely rotating propellers is adjusted in the manner set out in Specifications 12544/15, 101,280, and 103,160, [all in Class 114, Ships, propelling]. The rearmost propeller A is mounted on solid shaft connected by a Hooke's joint C to a solid shaft D passing into the hull through a stuffing-box E formed on the end of a hollow shaft D'. The inner propeller A<1> is carried by a tubular shaft B<1> rotatably mounted on the shaft B and connected by a Hooke's joint C<1> provided with a ring K instead of the usual cross.piece to a hollow shaft D' passing into the hull through a stuffing-box E<1>. Inside the hull the shafts D, D<1> are provided with gear wheels F, F' rotated by pinions i, i<1> driven by the same or separate electric motors. The transverse propeller q is rotated by an electric motor e acting through a shaft and bevel gearing s. The blades are mounted on a casing c and are capable of having their pitch adjusted by a shaft b acting through bevel gearing s<1>and tubular shaft t. The shaft b is normally rotated synchronously with the shaft a, by means of a band or chain l. To enable the shaft b to be rotated at a greater or less rate than the shaft a, the chain wheel l<1> is connected to the shaft through a cylinder k and piston k' coupled by a yoke z to a nut y engaging a quick threaded screw x on the shaft. The position of the slide valve k<11> is controlled by a knob rotating in a channel formed in a member u adapted to be screwed on to a boss w<1> by a pinion v actuated by any convenient primemover.

Title: Window blind actuating gear
IPC: E06B9/68
Filed: 1958-02-07
Abstract: 879,542. Window blinds. METALLBAU, A. G. Feb. 7, 1958 [Feb. 8, 1957], No. 4055/58. Class 20(3) [Also in Group XXXIV] In a blind actuating device with driving and driven shafts, 3, 2 respectively at an angle to each other, the driven shaft 2 is slidable longitudinally in the gear casing 1 and the gears 5, 7 are retained in position by the driven shaft and the form of the casing in such a way that by sliding the shaft 2 out of the-casing the gears are removable. The gear 7 is a bevel gear mounted on a sleeve 8 which rotates freely on the shaft 2. At each end the sleeve has diametrically opposed recesses 10 so that either end of the sleeve may be brought into engagement with a pair of similarly disposed teeth 9 carried by a disc 12. From the disc extends a sleeve 13 the end of which is cut away to form a section 17. A sleeve 19 is keyed on to shaft 2 and ends in a section 18 corresponding to section 17. A coil spring 15 preferably of rectangular section is located within the casing 14 as shown. When drive is transmitted from shaft 3 to the section 17 the coil spring is tensioned and its diameter reduced. Section 17 then acts on section 18 and shaft 2 is rotated. If, however, drive is transmitted through shaft 2 by e.g. the weight of the blind, section 18 acts on the spring 15 so as to cause its diameter to increase, thus pressing the spring against the interior of casing 14 and preventing rotation of shaft 2. The gear casing 1 has a releasable cover 1a.

The fittings D, D' are preferably mounted in a slotted tube A on which the springs are carried and the cord guides F, F' are mounted in the end brackets B', B<2> by which the device is supported. To release the catch a further pull is given to the cord causing a ramp H<3> on the catch H to ride up the pin H' to free the catch when, upon release of the cord, the springs C will retract and open the curtains. The brackets B<1>, B<2> may be provided with splined sockets in which hexagonal sectioned spigots on pelmet-supporting arms can be adjustably fitted and the brackets may also carry suspension devices for the single curtains for the sides of bay windows.

Filed: 1926-02-15
Abstract: 265,777. Carpmael, W., (Chemische Fabrik auf Actien, vorm. E. Schering). Feb. 15, 1926. Organic auromercapto acids and salts are prepared by treating organic mercapto acids and salts with auric compounds in the presence of sulphur dioxide or an acidic or neutral salt of sulphurous acid. According, to the examples, (1) sodium y - mercaptoglycerin - a - sulphonate is treated with potassium auribromide in aqueous sulphur dioxide or sodium bisulphite solution, and yields sodium auromercaptoglycerinsulphonate; (2) potassium auribromide is added to an aqueous solution of sodium p-mercaptobenzenesulphonate containing sulphur dioxide or sodium sulphite; (3) 4-amino-2-auromercapto-1-carboxylic acid is obtained by adding a sulphurous acid solution of potassium auribromide to 4- amino-2-mercaptobenzene-1-carboxylic acid. Sodium-gamma-mercaptoglycerin-a-sulphonate is obtained by treating sodium gamma-chloroglycerin-a-sulphonate with sodium sulph-hydrate. Sodium p-mercaptobenzenesulphonate results when the product of the interaction of p-diazobenzenesulphonic acid and sodium sulphide is reduced with aluminium amalgam.

A roller 19 throws the tobacco down a trough 20 on to a conveyer belt 21 and a belt 44, which may be arranged obliquely, tends to forward the tobacco in the direction of movement of the belt 21. The belt 21 confines the tobacco in a channel 22, Fig. 5, formed by a disc 26 between two larger rotating discs 24, 25 until it is delivered over a bridge-piece 33 to the cigarette-rod former. The tobacco in the channel 22 is compressed by mounting the disc 26 on an adjustable eccentric 30 and causing it to rotate with the discs 24, 25 by a pin 29 passing through radial slots 32. The cigarette paper is either fed through a groove 36 into the former or fed around the channel 22. In a modified form of tobacco feeding apparatus, a small raking drum is arranged over the drum 11 and picker rollers deposit two streams of tobacco on the belt 17.
