Title: Improvements in and relating to the production of metal wires and the like, and dies therefor
IPC: B21C3/14
Filed: 1922-11-08
Abstract: 210,868. Wardall, F., and Jakeman, B. Nov. 8, 1922. Wire.-Metallic filaments, ribbons, wires, &c. are produced by axially pressing a previously pointed metal bar &c. through a three-part die comprising an entrance portion, an exit portion and an intermediate canal formed in a refractory substance, the bar &c. being heated so as to become plastic during its passage through the canal. The exit portion D, Fig. 1, is separated from the entrance part B by a block C of refractory material such as an alloy of tungsten and white iron which may be cast round a metal core. The work is heated during its passage through the die by electric current or gas &c. On issuing from the die, the wire &c. may be passed through a tube F in which inert gas circulates and if desired the wire &c. may be passed through an electric annealing-furnace &c. which may be located within the tube F. A quenching-bath may also be provided for heat treatment of the wire &c. issuing from the die or annealing- furnace. The canal may be formed by a series of mutually insulated plates B, &c. Fig. II. carrying different potentials so that regulated temperature zones may be maintained within the canal. The die is formed with a clearance after its smallest section. The die may be used in conjunction with ordinary drawing processes. In a modification a diamond is used as a combined heating canal and die. In a further modification the entrance portion comprises a flanged tapered aperture round which the refractory material is cast.

Title: Improvements in or relating to the production of alcohols
IPC: C07D301/26
Filed: 1961-08-25
Abstract: Alcohols are prepared by (a) reacting a branched-chain olefin with an aqueous acid of formula HOX in which X is a halogen under known conditions for the hypohalogenation of a double bond so that a halohydrin is formed, (b) subjecting the haldrydrin to treatment with an alkali under known conditions for converting a halohydrin to a cyclic oxide so that the corresponding cyclic oxide is found and (c) subjecting the oxide to hydrogenation.  Mixtures of olefins may be used as starting materials. A preferred starting material is 4-methylpentene-1 obtained by the dimerization of propylene. The acid HOX may be formed in situ by the use of water and halogen, e.g. bromine. Suitable alkalis for use in step (b) are, for example, sodium carbonate or lime.  Step (c) is carried out in the presence of a catalyst, e.g. Raney nickel. In an example 4-methylpentene-1 is converted to 4-methylpentanol-1 and 4-methylpentanol-2.

Abstract: 1320787 Paper FELDMUHLE ANLAGENUND PRODUKTIONS GmbH 25 June 1970 [25 June 1969] 30866/70 Headings D2A and D2B  Bonded fibre fabrics or paper are produced on a paper-making machine by a process which comprises supplying all or part of the fibres in the dry state directly into the surface of liquid in the headbox of the machine by means of an electric field, and forming the sheet on the machine wire, all fibres larger than 6 mm. being supplied via the electric field. As shown, dry fibre is supplied to hopper 7, which is preferably vibrated, whence it is allowed to fall into headbox 1, electric generator 21 being connected between hopper 7 and brass plate 4 set into the floor of the headbox. Suction is applied at 3 behind inclined wire run 2, and also below a horizontal run. Plate 11 is provided to deflect and mix the pulp. The fibres added to the headbox may alternatively be self-charged by friction, when headbox water is earthed. Normal papermaking fibres may be present in the headbox liquid, a poly(acrylic ester) dispersion added to the pulp water, and a latex binder sprayed onto the web during drying. The fibres supplied by the electric field may be of polyamide, or of regenerated cellulose.

Abstract: 1533494 Floor sweepers LEIFHEIT INTERNATIONAL GUNTER LEIFHEIT GmbH 23 July 1976 [24 July 1975] 30885/76 Heading A4F In a floor sweeping machine having a flap 50 pivotally attached by a spindle 51 to the underside of a housing and defining dirt-collecting chambers 49 in front of and behind a main roller brush 26 driven by floor-engaging wheels 27, the roller brush 26 is rotatably mounted on the flap 50 and projects through an aperture 55 therein so that when the flap is pivotted downwards to empty the chambers 49 the brush 26 is accessible for cleaning. As shown in Fig. 13 the brush 26 is mounted in journals 100 on laterally projecting parts of the flap 50. A magnet 110 (Fig. 16) normally attracts a tongue 108 of the sheet metal flap 50 to hold the flap closed, a user opening the flap by grasping projections 54 and pivotting the flap against the magnetic attraction. The magnet 110 can be moved laterally on a rail 111 by manual adjustment of a control member 112 and, since the tongue 108 has an inclined bearing surface 107, this results in height adjustment of the flap 50 and roller brush 26 so that carpets of different pile lengths can be cleaned. A portion of the rail 111 is visible through a window 113 to indicate the height. The sweeper may have a frame and auxiliary brushes 56 con-  structed as disclosed in U.K. Specification 1529244.

White lead is produced by the action of corroding gases, for example, carbon dioxide and vapours of acetic acid and water, on lead buckles passing down a stack, inclined at an angle just greater than the angle of rest of the buckles, which, therefore, roll gradually along the bed. In addition, the overburden of the buckles and white lead is borne by the stack. Fig. 1 illustrates one form off apparatus which may be employed. Spherical foraminous lead buckles, Fig. 3, are fed through a hopper 4 into the top section 2. The end section 3 is provided with a closure 6 through which the corroded buckles are withdrawn, and at the interval of two sections, a cover 7 may be provided. The gases are supplied at the bottom of the stack.

Abstract: 280,945. Soc. of Chemical Industry in Basle. Nov. 18, 1926, [Convention date]. Addition to 238,704. Diazo salts of naphthalene trisulphonic acids.- The process described in the parent Specification for making diazo preparations from naphthalene trisulphonic acid is extended to diazo compounds in general, other 'than those derived from aminoazo compounds. The preparations are obtained by evaporating the diazo solutions with a neutral naphthalene trisulphonate, with or without the addition of a diluent or fixing agent, such as common salt, sodium sulphate or aluminium sulphate. The dried products, which behave like salts of naphthalene trisulphonic acid in which a free sulphonic group is present and dissolve m water with an acid reaction, may be mixed with an acid-binding agent, such as a bicarbonate, borax or chalk. In examples, (1) the acid diazo solution obtained by diazotizing o-anisidine is mixed with sodium naphthalene -1 : 3 : 6- or 1 : 3 : 7-trisulphonate, evaporated to dryness in a vacuum, and the product mixed with sodium bicarbonate, (2) the diazo solu'tions from 4-chlor- 2 anisidine and 4-chlor-2-nitraniline are evaporated in a vacuum with sodium naphthalene- 1:3:6- or 1 : 3 : 7-trisulphonate.

Abstract: 792,010. Motor-vehicle frames. DAIMLERBENZ AKT.-GES. Oct. 31, 1955 [Oct. 30, 1954], No. 31087/55. Class 79(4) [Also in Group XXXII] A chassis frame combined with the body of a motor vehicle to form a unit, comprises a hollow longitudinal bearer 110, and a hollow upstanding structure 126 which braces the front wall of the body (not shown) against the bearer 110. As shown in Figs. 4 and 5, a central tubular frame member 110 has a forwardly extending forked portion 111, 112, and a rearwardly forked portion 115. An upwardly extending sheet metal portion 125 rigid with the tubular portion 110, supports an upper transverse bearer 127 which also serves as an instrument panel. An additional transverse bearer is formed by a sheet metal member 124 which closes the front end of the portion 110 and a sheet metal portion 138 which is welded to struts 133, 134, which brace the portion 126 against the arms 111, 112. The change-speed gear-box 136 is disposed within the tubular portion 110 which also forms a tunnel for the propeller shaft 137. Transverse bearers 117, 118, connect the central portion 110 to longitudinally extending bearers 120, 121 which bound the sides of the body. In a modification (Figs. 1 to 3, not shown), the portion 110 is of uniform cross section instead of being of progressively increasing cross section as shown, but its effective cross-section progressively increases by the addition to the upper side of the portion 110 of a longitudinally extending U-shaped member of progressively increasing depth. The transverse bearer 127 is replaced by a transverse tubular member on which the instrument panel is mounted, and which also serves as a support for the steering column.
