Abstract: 427,541. Columns. RIDLEY, M. N., 82, Harold Terrace, Burley, Leeds. Sept. 25, 1933, No. 6828/35. Divided out of 427,473, [Group XXI]. [Class 20 (iv)] A column, stanchion, or like structure, comprises a tube which is constructed of sheeting 1<a> of plain, perforated, or expanded metal, formed with dovetail corrugations 3 arranged longitudinally of the structure, and is reinforced by internal transverse or diagonal bracing members 18, as shown in Fig. 2. The tube, which may be of circular or rectangular cross-section, may be further strengthened by a circumferential reinforcement 14 and by internal rings 15, and a concrete or like filling 9 may be provided. Each bracing member 18 may be bolted to the tube, or it may be secured by extending its ends through the opposite walls of the tube, or by means of a cement key 19 which engages a dovetail corrugation and a part of the bracing member projecting through the wall of the tube. A hollow structure may be formed of two concentric tubes 1, 1<a>, which are connected by radial bracing 18 as shown in Fig. 1 and are provided with a concrete filling 9. The outer tube 1 may be reinforced by bars 14 which are threaded through the corrugations 3 and are welded or otherwise connected at their ends. An additional or alternative reinforcement for the tube 1 consists either of a wire bracing or external rings or sheets 15. A further form of hollow column comprises two concentric tubes l, l<a>, Fig. 4, of square cross-section, with a concrete filling 9, and this construction may be modified by providing internal bracing members for the inner tube 1<a> and also, if desired, filling the inner tube with concrete. The column shown in Fig. 6 is of square cross-section, with flattened corners, and is reinforced by straps 15<a> which extend diagonally across the corners and are secured at one or more points to each wall of the tube by bolts 20 co-operating with cupped portions of the tube. External reinforcing rings 15 may also be provided. A series of diagonal straps 15<a> may be employed as shown in Fig. 7, together with corner straps 23, and the inner straps 15<a> are secured to an inner tube 1<a>, which may be additionally connected to the outer tube by bracing 18. A concrete filling 9 may be provided in either of the columns shown in Figs. 6 and 7. The tubes may be formed in one continuous length and width of sheeting or in units or sections detachably or otherwise secured together by lapping, butting, or nesting, or by the provision of flanges. Uncorrugated sheets may be fixed to either or both faces of the tubes. The outer surfaces of the tubes may be rendered with cement &c., and in the case of hollow structures, the inner faces may be similarly treated.

Filed: 1952-03-17
Abstract: 732,115. Continuous - casting machines. BRENNAN, J. B. March 17, 1952, No. 6849/52. Class 83 (1). Making composite strip.-Casting apparatus comprises a die 12 through which material, such as beryllium bronze, may flow from a crucible 3, at least one further crucible 1 having a closed conduit 20 leading to the crucible 3, and housings around said crucibles forming chambers having a pressure therein other than atmospheric. The crucible 3 is of aluminium oxide if aluminium is being cast and the metal therein may be agitated. The level of metal may be indicated by a float and the metal heated by a high-frequency coil 10, the temperature being indicated by a thermocouple 11. The die is heated by high-frequency coils 15, 16 and is cooled by insulating oil, refrigerated gas, water &c. in a jacket 17. A thermocouple 18 controls the energizing of the coil 16 or the circulation in the jacket 17 according to the temperature in the die. When electrodes are to be cast, the material consists of aluminium and aluminium oxide in proportion 1 : 4 by weight and nitrogen or helium may be supplied to the housings surrounding the crucibles 1 ... 3, at a pressure of 5-50 lbs./sq. inch. Alternatively, the housings may be evacuated to a pressure of 1-10 microns of mercury. Rolls 30, 30 give the material greater strength and cohesion as it leaves the die. By passing a strip 40, Fig. 2, through the die a composite steel-copper product may be produced. Feeding of the strip 13, Fig. 3, may be assisted by weighted rollers 50 which are periodically raised by chain gear actuated by a motor 55 and switches 53, 54. In a modification, the metal is cast into moulds or is removed from the crucible 3 by a rotating wheel. The atmosphere in the housings may be argon and may differ in each housing.

Title: Apparatus for reducing variations in tension in a web passing through a machine
IPC: B65H23/04
Filed: 1960-02-26
Abstract: 946,662. Automatic tension control. A. WINDMOLLER, and M. GENERICH, [trading as WINDMOLLER & HOLSCHER]. Feb. 26, 1960 [Feb. 27, 1959; April 22, 1959], No. 6899/60. Heading G3R. In a system for automatically reducing variations in tension of a web of material passing through a processing machine, currents, respectively proportional to the magnitude and rate of variation of tension and both derived from a movable core transformer operated through a pivoted lever by a constant force applying means suspended in a loop of the material, control the feed of the web through the processing machine. Variations in the tension of a web 1 being unwound from a reel 2 in a printing machine by feed rollers 6, 7 are detected by movements of a roller 13 which, through a pivoted lever 15, adjusts an iron core 21 of a transformer 22 and varies the current in a control winding 38 of a magnetic amplifier 40 so that the energization of an electromagnetic brake 5 on reel 2 is modified to restore the tension to a value selected by the positioning of a sliding weight 17. Movements of lever 15 are damped by an adjustable hydraulic dashpot 25 and a second control winding 39 of magnetic amplifier 40 energized through a condenser 49 introduces a rate component of control. In a modification the output of the amplifier controls the energization of an electric motor or electromagnetic coupling and a brake associated with a supplementary drive applied to a cooling cylinder through a differential gear. The energization of the brake is delayed by a resistance capacity network. Valve or transistor amplifiers are also referred to.

Title: Improvements in the manufacture and production of lubricants
Filed: 1934-03-17
Abstract: The synthetic processes specified below for the production of lubricants are carried out in presence of added nitriles or amines or other organic bases.  Bases and nitriles specified are aniline, naphthylamine, phenylnaphthylamine, aminoethylbenzene, aminoanthraquinone, aminobenzaldehyde, aminobenzophenone, diphenylamine, benzylamine, acetonitrile, benzonitrile, naphthonitrile, pyridine, quinoline, carbazole.  0,05--10,0 per cent is suitable.  The synthesis may be effected by polymerization and condensation of olefines, mineral or tar oils, waxes, fats, high molecular acids or alcohols, in presence of aluminium chloride, zinc chloride, iron chloride or like catalyst; or by the hydrogenation of rubber, resins, or other polymers of high m.w.  The synthetics may be added to lubricating oils or greases to reduce the setting point and improve the viscosity index and stability.  For example, 100 lb. of chlorinated paraffin wax is diluted with 100 lb. of kerosene, and condensed at 30--40 DEG  C. for 24 hrs. with 10 lb. of naphthalene in presence of 3 lb. of carbazole, 7 lb. of aluminium chloride, and 6 lb. of zinc oxide. The inorganic matter is removed by centrifuging, the diluent by distillation, and the unchanged wax and light lubricating oil by steam distillation in vacuo.  3 lb. of the cylinder-oil-like product added to 100 lb. of mineral machine oil reduced the setting point 25 DEG  C.

Patent GB-194719-A (GB)
Title: Manufacture of anhydrides of fatty acids of low molecular weight
IPC: C07C51/56
Filed: 1923-03-10
Abstract: Anhydrides of fatty acids of low molecular weight are produced by heating the fatty acid to a temperature between 400 DEG  and 800 DEG C. in the absence of catalysts which determine a decomposition of the acid in other directions.  Thus, acetic anhydride is obtained by rapidly conducting acetic acid vapour over pieces of fireclay heated to 650 DEG  C.; propionic and butyric anhydrides are produced in like manner.  The products are preferably quickly cooled; indifferent gases or vapours may be admixed with the acid vapour before it enters the heating zone; or liquids, such as volatile hydrocarbons, may be injected into the products of dissociation to assist the cooling and desirably to precipitate the water formed. Catalysts may be present which favour the formation of the anhydride, e.g. chlorides and sulphates of alkali and alkaline earth metals, boric acid and borates.

Convention dates, March 9,1935, March 11, 1935, and April 15, 1935. [Class 140] A rubber-coated fabric for raincoats &c. is reinforced by a thin, open fabric or net secured by the rubber coating. The open fabric may be laid upon the main fabric and the assembly coated with rubber and vulcanized. A design may be formed with the apertures in the open fabric, e.g. closely-woven and openwoven zones or strips may alternate. The closely - woven strips may be impermeable to the rubber coating, thus producing local non-adhesion of the fabrics. The net fabric and rubber coating may be cut at these non-adhered zones to give continuous or interrupted ventilation slots. The main fabric may be stretched before the open fabric and rubber coating are applied thereon, or may contract on vulcanizing, so that, when the tension is released, or after vulcanizing, the open fabric forms ridges at the non-adhered portions. The non-adhered portions, if cut at these ridges, form a stepped or overlapping arrangement, as shown. The fabric and the open net reinforcement may be woven as a double fabric which is rubber-coated and vulcanized.
