Title: Improvements in or relating to machine tools
IPC: B27B5/20
Filed: 1950-06-28
Abstract: 699,689. Rotary saws; grinding machines. KEARNEY & TRECKER CORPORATION. June 28, 1950 [July 18, 1949], No. 16141/50. Classes 60, 124 and 145 (ii). A radial machine tool which employs a rotary tool (a saw, or grinding wheel) may be used for stone cutting and wood routing as well as general sawing and grinding. The rotary tool is so carried that it may cut in a direction truly radial to the vertical supporting column whereby angular positioning of the tool is facilitated. A main column 14 carries a ram 23, the forward end of which carries a yoke 71 which can thus be adjusted radially. The yoke is pivoted about a vertical axis 74 and is offset so that a motor 65 is horizontally pivoted about the axis 73 and the saw or other tool 67 rotates in a radial plane passing through the axis 14 coincident with the vertical axis of the column 14. The tool can be set at an angle relative to the vertical by withdrawing plunger 76 and allowing it to re-engage one of a series of holes 77. As the saw axis is in the plane of the column axis it is possible to adjust the saw at an angle relative to the horizontal without the necessity of correcting for an unwanted bodily displacement of the saw. Side plates 116, 117 are pivotally mounted at 118 and function to guard the operator from contact with the tool. A work-supporting table 88 carries a ripping guide 89 and a slot 91 to receive a second, removable, guide 92. A plurality of cam-like locking devices 93 engage hardened buttons secured to the frame 92 to lock the latter in position. The saw is adjustable vertically by varying the position of the ram support and the vertical column (around which it can rotate) the column being movable in the housing 11.

Title: New or improved means for the decortication of fibrous vegetable stems
IPC: D01B1/22
Filed: 1950-06-29
Abstract: 693.833. Decorticating machines. THOMPSON, H. D., WIGHTWICK, H.D., and RHODESIAN JUTE INDUSTRIES, Ltd. [formerly VANDENBERGH BLACK & CO., Ltd.] June 26, 1951 [June 29, 1950], No. 16243/50. Class 120(i) A machine for decorticating fibrous vegetable stems or stalks comprises a series of co-operating but independently rotatable splitting rollers through which the stems are successively fed and which are adapted to split the stems lengthwise and loosen the fibre-containing bark from the central core, in combination with a separating roller arranged at the rear of the last pair of splitting rollers and rotating in the opposite direction to the bottom roller of the last pair of splitting rollers to separate the bark from the core and take it off at an angle to the direction of movement of the core. As shown, stems are placed by hand in a feeding box 14, comprising longitudinal bars, through which the stems fall in longitudinal alignment onto a belt 13 which feeds them to feed rollers 15, 15' and splitting rollers 21, 21<SP>1</SP>. 22, 22<SP>1</SP> and 23, 23<SP>1</SP>. The upper roller of each pair is of smooth-surfaced steel and is spring-pressed towards the lower roller which is covered with rubber or similar material. Alternatively, the roller surfaces may be roughened, grooved or ribbed. The stems are split longitudinally by the splitting rollers and flattened into ribbon form with the split bark below the cores. The splitting rollers of each pair may be spaced apart, each successive pair being arranged closer together than the preceding pair so that the stems are progressively flattened. On leaving rollers 23, 23<SP>1</SP> the split bark, being soft and flexible, drops between roller 23 and a contra-rotating ribbed separating roller 26 to bark delivery rollers 27, 27<SP>1</SP> and a delivery apron 28. The cores, being stiffer than the bark, pass over roller 26 and below an idler roller 29 which guides them to core delivery rollers 30, 30<SP>1</SP> and a delivery shoot 31. Rollers 26, 27, 27<SP>1</SP>, 29, 30 and 30<SP>1</SP> are all mounted in a sub frame 32 which is adjustable about the axis of roller 23 to adjust the angles at which the bark and core are taken off relative to the feed. Stripping roller 26, instead of co-operating with roller 23, may co-operate with a separate roller or with a stationary plate or brush. The machine may be stationary, or made as a portable unit for mounting on a trailer.

Title: Improvements in or relating to cellulosic textile materials suitable for use in manufacturing laminated articles, composite articles made therefrom and methods of making such materials and articles
IPC: C08J5/06
Filed: 1940-11-09
Abstract: 546,171. Fabrics &c. containing rubber or rubber-like substances. FIRESTONE TYRE & RUBBER CO., Ltd. Nov. 9, 1940, No. 16281. Convention date, Nov. 10, 1939. [Class 140] A material containing rubber-like substances and suitable for making tyres, belts and other laminated or composite articles is made by impregnating fabric filaments, threads, cords &c. with a dispersion containing a mixture of rubberlike substance and protein, drying and heating above 100‹C. for a period sufficient to produce maximum adhesion to a layer of rubber composition which, after such heating, is applied thereto and vulcanized. In one example the impregnating liquid contains 5 per cent. soya bean protein and 12 ¢ per cent. rubber, 10 per cent. of the weight of protein being used to solubilize it.' Rayon cords are dipped in this and heated at 135‹C. for one hour. This material is then calendered to a backing consisting of a usual tyre body composition on woven fabric and vulcanized. In another example the above impregnating composition contains also 5 per cent. casein solubilized by 15 per cent. sodium cresylate, the percentage being that of the weight of casein. In a third example 4 per cent. casein solubilized by 21 per cent. sodium cresylate and 15 per cent. rubber is used. The heat treatment may be in a vacuum or in an oxygen-containing. atmosphere. The rubber dispersion may be of natural or artificial and of unvulcanized or reclaimed rubber ; the dispersion may also be of neoprene or of polymers based on butadiene or of other rubber-like substances. The times and temperatures of the heat treatment may be varied. The protein may be stabilized by a fixed alkali such as lithium, sodium or potassium, or by hydroxides, carbonates, phosphates, borates, silicates, tannates, fluorides, oxalates, tartrates, phenolates, cresylates &c. Sodium or potassium phenolates or cresylates are particularly desirable. Ammonia or amines may be used. For proteins, zein, from corn, and cotton-seed protein may be used. For the fabric, cotton or regenerated cellulose may be used.

Patent GB-489978-A (GB)
Title: Improvements in or relating to the production of hydrogen peroxide
IPC: C01B15/023
Filed: 1937-06-15
Abstract: In the production of hydrogen peroxide by cyclically reducing an azo-type compound containing no polar substituent atom or group in an alkaline medium and oxidizing the resulting hydrazo-type compound by means of an oxygen-containing gas, in a solvent in which the hydrazo-type and azo-type compounds are soluble but in which the hydrogen peroxide formed is insoluble, this solvent being immiscible with water and being maintained during the oxidation step in contact with a predetermined quantity of water sufficient to dissolve the hydrogen peroxide formed and produce a solution of the required concentration, the hydrazo solution is rendered non-alkaline following the reduction and prior to the oxidation and thereafter the oxidation is effected in a non-alkaline medium.  The reduction may be effected by means of alkali metal amalgam and water or aqueous alkali hydroxide and tin or zinc.  The hydrazo solution may be rendered non-alkaline by washing extensively with water or by washing with an aqueous acid medium, e.g. aqueous sulphuric acid or sodium dihydrogen phosphate, after it has been separated from the amalgam and the aqueous portion of the reduction mixture.  The reduction stage may be carried out in the presence of an inert gas and the solutions of the hydrazo compounds may be maintained in an inert atmosphere of nitrogen, hydrogen and/or helium while they are being processed and stored prior to the oxidation.  In the oxidation, it is preferable to introduce the oxygen-containing gas at the bottom of the reaction vessel as minute bubbles and to agitate the reaction mixture so that the limited amount of water present remains suspended in the form of an emulsion.  The reduction step may be effected at 57 DEG  C. and the oxidation step at 57-59 DEG  C.  Examples relate to the alternate oxidation and reduction of a solution of para-hydrazotoluene in benzene. Specification 461,589 is referred to.  The Specification as open to inspection under Sect. 91 comprises also the application of the process while using 2-amino-5-azotoluene.  This subject-matter does not appear in the Specification as accepted.

Abstract: 775,727. Electronic counting-apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 9, 1955 [June 14, 1954], No. 16589/55. Drawings to Specification. Class 106 (1).  An electronic storage device comprises a group of denominationally ordered glow transfer tubes each tube having an anode, ten digit representing cathodes, a transfer cathode positioned between each consecutive pair of digit cathodes and an inversion cathode between each pair of digit cathodes representing complementary values, and is characterized in that to read a decimal digit from a punched record card into any particular tube, ten cam-produced negative pulses are applied to the transfer cathodes in synchronism with the sensing of successive rows of the record card and on the sensing of a hole, which causes a thyratron to fire, a negative voltage is applied to the inversion cathodes causing the glow discharge to step to an adjacent inversion cathode where it remains until the remainder (if any) of the ten cam-produced pulses have been applied, when the said negative voltage is removed and the glow discharge steps to the associated digit cathode. For example, if a hole representing the digit 7 is sensed (the nines row being sensed first), the first 2 pulses applied. to the transfer cathodes are effective to step the glow to digit cathode 2, then a negative voltage is applied to the inversion cathodes stepping the glow to the 2/7 inversion cathode, the remaining 8 pulses are applied to the transfer cathodes being ineffective, and finally the negative voltage is removed from the inversion cathodes causing the glow to step to digit cathode 7. Read-out is accomplished by using the differentially-timed energizations of the digit zero cathodes to fire punch-magnet controlling thyratrons. Specification 734,903 is referred to.

Abstract: 546,022. Glass manufacture. PARFITT, A. W. (Owens-Illinois Glass Co.). Nov. 21, 1940, No. 16734. [Class 56] A machine for making hollow glassware, particularly a machine of the Owens type, is provided with hydraulically operated pistonmotors for raising the finishing moulds to enclose the parisons, and with means for preventing a finishing mould from being raised unless the parison mould with which it cooperates is opened fully. The machine comprises a mould carriage 110 which is rotated continuously about a hollow vertical column 100 by hydraulic means, but the speed of rotation is varied periodically in the manner described in Specification 545,548. The carriage 110 has five mould units each comprising a parison mould 102, a neck mould 103, and a finishing mould 104. To permit the parison moulds being lowered into contact with the pool 105 of molten glass, they are carried by dip heads 107 which are lowered by gravity and are raised by pneumatic piston-motors A, one for each head. The lifting and lowering movements are under the direct control of a continuously rotating cam 108 which positively controls the movement of the dip heads in a manner similar to that described in Specification 545,549. Each finishing mould 104 is mounted on a carrier 255 which is reciprocated vertically by a hydraulic piston-motor H<SP>1</SP>, and is given a swinging movement by a stationary cam 256 to move the mould to and from parisons suspended from the neck mould. Each parison mould 102 is opened and closed by a stationary cam 445 in which runs a cam roll 446 secured to a slide block that operates the mould halves through a vertical shaft. A valve, mounted on the mould carriage, is operated by contact with a slide block when the mould is opened and allows the piston-motor H<SP>1</SP> to raise the finishing mould, but prevents the raising of the finishing mould unless the parison mould is opened fully. A manually-operated device is also provided for permitting any desired finishing mould from operating temporarily while the remaining moulds are operating normally. In a modified construction, the mould carriage is not rotated by hydraulic means, but is driven by an electric motor running at a constant speed. The motor drives the mould carriage through a gear box which is oscillated about the driven shaft in order to give the periodic slowing-down in the rotation of the carriage.
