Title: Improvements in cutting apparatus for use in connection with tube rolling mills
IPC: B23D45/18
Filed: 1933-10-04
Abstract: 429,829. Circular - saw machines. TRAUT, R., 69, Friedrichstrasse, Mulheim, Ruhr, Germany. Oct. 4, 1933, No. 27358. Convention date, Dec. 24, 1932. [Class 145 (ii)] [See also Group XXII] Metal tubing emerging continuously from a rolling mill is cut into lengths by a cutter, as e.g. a circular saw 30, Fig. 4, carried by a wheeled carriage 26 ; the saw 30 and its driving motor 29 are mounted on a table 28 rocking about a spindle 27 and normally held in the horizontal position by a spring 31 ; a lever 32 mounted on the spindle 27 has a projection engaging the table 26, the lever engaging a fixed cam surface 33 during forward movement of the carriage to rock the saw into the work. A channel 36 on the carriage and fixed channels 37, 38 are provided. A roller train (not shown) removes the severed lengths. The cutter carriage 26 is connected by a rod 24, Fig. 2, to an arm 16 mounted on a shaft 14, the other end of which carries an arm 13 oscillated through a connecting rod 12 by a crank 11 driven through gear wheels, worm drive 6 and change speed gear 5 by the motor 1 which drives the rolling mill through gearing 2. The cutter carriage 26 is thus continuously reciprocated at a frequency governed by the rate of feed of the tube, so that any fluctuation in the latter will not affect the length severed. The speed of the carriage at the moment of cut is arranged to be the same as that of the tube, so that no drag is exerted. To alter the length severed, the frequency of the cutting operation is altered, and at the same time the extent of the reciprocating movement is varied in such a manner that the speed of the carriage at the moment of cut is still equal to that of the tube. The connecting rod 24 is connected to a block moved in the arm 16 by a screw spindle actuated through bevels 19, 20 and worms 21, 22 by a motor 23 so that the stroke of the carriage 26 can be varied ; the motor 23 simultaneously adjusts the change speed mechanism 5 through gearing 39, 40, 42, 44 thereby altering the frequency of reciprocation of the cutter carriage.

Abstract: 1462902 Bottle cleaning machine SEITZWERKE GmbH 20 June 1974 [12 July 1973] 27425/74 Heading B8T A bottle cleaning machine comprises a carriage 15 on which are mounted a plurality of spray nozzles 21, the carriage being supported by bearings 24 and being reciprocated in a horizontal plane by cam means 17, the bearings 24 consisting of metal balls which reciprocate within elongated troughs 25, the motion being limited by end stops 26, 27. L-section support members 23, integral with the carriage 15 rest on the balls and together with the troughs 25, define ball races. Inverted bottles are conveyed in holders 13 which travel in a plane above that containing the nozzles 21 and for a part of the cam cycle, the nozzles move in the same direction as the bottles, with the same speed and with holders 13 disposed vertically above the nozzles which are therefore able to spray cleaning fluid into the interior of the bottles. During the next part of the cam cycle, the nozzles are caused to move in the reverse direction with greater speed until they are disposed vertically below another set of bottles immediately following those previously cleaned, after which the cam means 17 again causes the motion of the nozzles to reverse direction and the cleaning cycle is repeated. Transverse motion of the nozzles is prevented by wheels 29 bearing against the side walls (not shown) of the machine. In an alternative embodiment, the wheels 29 are replaced by a set of ball bearings which reciprocate within races integral with the side walls.

Filed: 1923-11-06
Abstract: 206,836. Electro Metallurgical Co., (Assignees of Becket, F. M.). Nov. 13, 1922, [Convention date]. Alloys of the rustless type containing upwards of 8 per cent of chromium, including rustless iron, stainless steel, and low-carbon allovs of chromium with nickel or cobalt or both, with or without iron, are made by reducing a chromium ore at a high temperature by means of a non- carbonaceous reducing agent, which may be aluminium, silicon or ferro-silicon, or preferably a chrome-silicon or ferro-chrome-silicon alloy, and diluting the product at a lower temperature with iron, or with the other required metal, either added in the metallic form or as a reducible mixture ; or the alloys may be made by reducing chrome ore by chromium-silicon alloys followed by dilution of the product with the main part of the metal to be alloyed with the chromium. The operation is preferably carried out with the aid of a layer of basic slag, the alloy being tapped off at intervals, leaving in the furnace a small quantity of metal and slag for the next charge. Manganese and other deoxidizing and other additions may be employed in the usual manner. In the electric furnace, which may be a tilting furnace, with a basic lining and with small adjustable carbon electrodes, a small charge may be first melted, the operation being started by the aid of a train of metal fragments or by means of a removable carbon rod lying between the electrodes.

Patent GB-673458-A (GB)
Title: Improvements in electron emissive bodies, especially cold cathodes, and methods for their preparation
IPC: H01J17/06
Filed: 1950-11-15
Abstract: A cathode, e.g. a cold cathode, is made of metal which has a melting point above 1300 DEG C. and has a surface of barium oxide with 1-3 per cent nickel.  A nickel cathode is rinsed in trichlorethylene, heated for 15 minutes to 1200 DEG C. in wet hydrogen and sprayed on its back surface with a suspension of aluminium in amyl acetate which is then heated to 925 DEG C. for 15 minutes in dry hydrogen to sinter and oxidize the aluminium, sufficient oxygen being present for this purpose.  Further heating for 5 minutes at 700 DEG C. in nitrogen containing 5 per cent oxygen increases the ability of the surface to be wetted by the coating, which consists of barium carbonate and 10 per cent nickelous oxide, which has been passed through a 400 mesh sieve; the vehicle consists of pyroxolin in amyl acetate and the coating should weigh 3.3 m.grams per sq. cm.  The cathode is heated in flowing purified nitrogen in a furnace in which the temperature is raised in 20 minutes from 700 DEG C. to 1300 DEG C. which is held for 30 minutes.  The cathode is removed when the furnace temperature falls to 600 DEG C. and stored in a vacuum until assembled within a discharge tube.  It is preferable that the heating should be adjusted so that the eutectic of barium carbonate and barium oxide is temporarily formed at 1000 DEG C. although this could be eliminated if the temperature was held at 950 DEG C. to decompose the carbonate.

Patent GB-1071183-A (GB)
Title: A process for production of bonded fibrous structures such as synthetic leather
IPC: D04H1/54
Filed: 1964-07-09
Abstract: A process for producing non-woven bonded fibrous fabrics, particularly artificial leathers, comprises forming a web of fibres of at least one high molecular weight material having secondary amino groups the material having been treated chemically at some stage to substitute the hydrogen atoms of some of the amino groups, so that the web contains fibrous material some of which is dissolved in a given solvent which is applied to the web to cause the fibres to adhere together the remainder of the fibrous material being either insoluble or less soluble in the solvent.  Suitable materials having secondary amino groups include various polyamides and copolymers based thereon, polyurethane, polyurea and polypeptide.  Other high molecular weight materials having no secondary amino groups which may be used together with those having such groups include polyethylene, polypropylene, polystyrene, polyester and polyoxymethylene.  The chemical treatments which affect the solubilities of the fibres by substituting the hydrogen of the amino groups include methylolation, oxyethylation, polyoxyethylation, polyoxymethylation, alkoxymethylation, substituted alkoxymethylations, thiomethylolation and alkylthiomethylation, and these reactions may be carried out before or after formation of the material into fibres.  In the examples given various solutions of formaldehyde, paraformaldehyde and liquid ethylene oxide are referred to for effecting the chemical treatments.  The fibres may be wetdry-, or melt-spun and blends of the various high molecular weight materials referred to above may be co-spun to provide fibres containing the two or more constituent materials.  The fibres may be crimped, as in Examples 1, 5 and 8. Random webs of the fibres may be laid by a random webber and needle punched as in Examples 1 to 7 and two or more similar or dissimilar webs may be laminated together as in Examples 2 and 8 before solvent treatment is undertaken.  Suitable solvents which dissolve the substituted fibres or those parts thereof e.g. surface parts, which are substituted but not the unsubstituted parts or fibres include alcohols, acetone, ether and other conventional solvents.  In Examples 5 to 8 heat is applied together with the solvent.  The bonded fabrics produced may be further impregnated with substances such as an initial condensate of urea, formalin, or melamine, polycondensable substances such as ethylene oxide, ethylene imine and silicon tetrachloride, vinyl compounds such as vinyl chloride, vinyl acetate, acrylic acid, acrylonitrile, and methacrylic acid or polymers or copolymers thereof in emulsion form; subsequent polymerisation or condensation may be effected by heat, chemicals, high frequency wave treatment or irradiation or alternatively heat may be applied to melt the substance and thus to strengthen the fibre adhesion.
