Title: An improved process for the production of hydrogen peroxide
Inventor: SKULL ALAN
IPC: C01B15/023
Filed: 1960-09-21
Abstract: Anthraquinones are regenerated from the degraded anthraquinone constituents of a working solution of anthraquinone in a solvent used for hydrogen peroxide production, by contacting the working solution with a defined porous granular substance which contains adsorbed base.  Alternatively the degraded anthraquinone constituents may be extracted from the working solution and made up into a fresh solution before contact with the alkali treated solid.  The porous granular substance, e.g. silica gel, kieselguhr, silica alumina or sodium aluminium silicate, may have a surface area of 30 sq. m./gm.  The base may be an alkali metal carbonate, bicarbonate, hydroxide or triethylamine or pyridine. The solid, after alkali treatment, may be washed and/or dried. The working solution treated may be oxidized, reduced or partly reduced and may be concentrated. In a cyclic process involving in succession reduction of an anthraquinone oxidation of the anthrahydroquinone and aqueous extraction of hydrogen peroxide, 10% of the solution may be withdrawn from the hydrogen peroxide extraction stage, treated at at least 75 DEG  C. and returned, or a mixture of solution after and before extraction may be treated.  A number of specific anthraquinones and solvent mixtures are referred to and the proportion of solid is 5-10%. Specification 465,070 also is referred to.

Title: Improved truing device for the grinding wheels of precision grinding machines
IPC: B24B53/04
Filed: 1946-11-01
Abstract: 618,201. Dressing grinding wheels. CHURCHILL MACHINE TOOL CO., Ltd., and ASBRIDGE, G. H. Nov. 1, 1946, No. 32474. [Class 60] A wheel-truing device for the grinding- wheels of precision grinding machines is adapted to be mounted on the machine wheel-head and comprises a handle moved back and forth to traverse the truing diamond across the wheel face, which handle when pressed with a pressure sufficient to overcome a spring resistance at the end of a traverse also effects a feed movement of the truing diamond into or towards the grinding-wheel. A diamond g, on a bar f slidable in a housing e and having a rack h fastened thereto, is reciprocated across the periphery of a grinding-wheel c by the oscillation, by a handle k or a handle m, of a pinion i keyed to the handle shaft and engaging the rack h. If the bar f is given an additional movement to the right, Fig. 2, a rod o, spring- pressed against the end thereof and connected to an L-shaped bar p, moves a pawl q, carried by the bar p, to turn a ratchet-wheel r threaded on a screw s and thus move the housing e relative to a fixed bracket a. The tool g is thus fed into the grinding-wheel c. In order to steady the traversing movements of the bar f, a double-acting plunger y is traversed in a cylinder w by the pinion i simultaneously with the traversing movements of the bar f. The flow of liquid from one end of the cylinder w to the other is restricted by ports a; so that the arrangement serves as a double-acting dashpot.

Title: A process for preventing laddering in knitted fabrics
IPC: D06M15/59
Filed: 1955-11-16
Abstract: In the manufacture of knitted fabrics from single filaments of a synthetic resinous material in which the filaments cross without being actually knotted or tied, the filaments are treated, before or after knitting, with a solution containing at least one solvent for the filament, at least one liquid diluent miscible with the solvent but incapable of dissolving the filament, and a water-insoluble polymer miscible with the synthetic resinous material of the filament and soluble in the solvent-diluent mixture, and thereafter the treated filament or fabric is dried. The filaments may be of a polyamide and the treating polymer may be the same or another polyamide, polyvinyl formal, polyvinyl acetate or polyvinyl butyral. The liquid mixture may be such that the diluent evaporates more quickly than the solvent or vice versa, and in the latter case the mixture may be incapable of dissolving the filament at room temperature but will do so at raised temperatures, in which event the material may be dried at the temperature at which the liquid will exert a dissolving action.  In Example (1) nylon stockings are treated according to a pattern with a solution containing a polyamide 6-6, phenol and acetic acid and dried at 60-70 DEG  C., and nylon stockings are similarly treated in Example (2) with a solution containing a polyamide, formic acid and acetic acid and in Example (3) with a solution containing acrylonitrile - butadiene copolymer, phenol, acetic acid, toluene, and methyl ethyl ketone.  In Example (4) a nylon filament is treated at intervals along its length with a solution containing polyvinyl formal, formic acid and acetone.  A stocking, knitted from the treated filament, is stretched and treated in this condition with a mixture of toluene and ethanol by immersion or with their mixed vapours at 50 DEG  to 80 DEG  C.  The toluene may be replaced by dichloroethane or cyclohexanone. Specification 685,623 and U.S.A. Specification 2,308,593 are referred to.

Title: Improvements in or relating to ventilators
IPC: B63J2/10
Filed: 1934-11-15
Abstract: 440,453. Ventilators. GREEN, B. M., 900, New York Avenue, Brooklyn, New York, U.S.A. Nov. 15, 1934, No. 32890. [Class 137] A ventilator, operating by the action of wind, comprises a conical flared member A having a number of spaced spiral vanes B on its outer surface, each vane being curved in cross-section with the concave side towards the narrower end of the member A, and its curvature decreasing along the length of the vane from that end. In the case of an intake ventilator, the air caught by the curved vanes B is driven through a vaned ring F which prevents the entry of water into, and, due to the direction of slope of the vanes; impedes the exit of air from a hood E which covers the top of the ventilation shaft D and cone A. Pressure consequently builds up in the hood E, and air passes downwardly through the shaft D. A disc H<2> operated by a handwheel H<1> closes the shaft D. An annular disc A<1> may be used to form an additional splash plate. When used as an exhaust ventilator, air caught by the vanes B, Fig. 7, passes downwardly through vertical vanes K<1> extending inwards from a curved shield K, which, due to its curvature increases the downward suction which exhausts air through the shaft D.

[Also in Group VIII] A magnetic record medium comprises powdered magnetic material such as red or black iron oxide mixed with a nylon binder and applied to a non-magnetic backing which may be a belt tape, or disc of nylon, glass, metal or wood. The backing may bear spiral or endless tracking grooves 15, the magnetic coating being applied between the grooves, at 10, on the opposite surface 17 or on a part of the backing away from the grooves. The coating material is made by suspending the oxide in a solution of nylon in a suitable mixture of solvents. The oxides may form 70-90 per cent by weight of the coating material. A machine for applying it to the backing material by roller is described (see Group VIII). The magnetic particles, which may be “-1/5 by 1 micron in size, may be orientated as the coating is applied by the application of a magnetic field, and after coating by calendering with a hot polished roller which also smooths the surface. To prevent coating defects when the backing is a belt, resulting from stopping and starting, the coating is applied in a number of steps, each constituent layer being formed by rotating the belt a number of times. Each constituent layer may be separately dried. Specification 800,842, [Group XVI], is referred to.
