Abstract: 1,191,334. Injection-moulding footwear. BRITISH BATA SHOE CO. Ltd. 24 July, 1967, No. 33896/67. Heading B5A. Injection moulding apparatus for making shoe soles in two layers comprises a plurality of moulding units 20 each including a sole mould 90, a movable last 40 and movable side moulds 60, the last, sole mould and side moulds together defining the moulding cavity, the sole mould being movable from a first position defining a first moulding cavity to a second position defining a second moulding cavity, and first and second injection units 111 which are stationary relative to the moulding units, the latter being mounted on a rotatable table top 4 so that they are brought into communication first with the first injection unit which injects a first moulding material into the first mould cavity and then the second injection unit where a second material is injected into the second cavity. In this way shoe soles having two layers of different colour, physical properties or chemical composition may be obtained. A cooling plate 115 is provided for cooling the sole mould after the first injection so that the material solidifies in the injection canal and ports provided in the sole mould 90 and can be removed during the travel of the moulding unit from the first to the second injection unit. The material solidified in the canal and ports after the first and the second injections may be removed automatically. A toe cap mould 98 may also be provided.

Title: Manufacture of soluble polyvinyl alcohols
IPC: H04R1/12
Filed: 1955-11-25
Abstract: Polyvinyl alcohol having a viscosity of more than 140 centipoises (4 per cent aqueous solution) is produced by hydrolysis of polyvinyl acetate prepared using 0.8 to 8 per cent of dioleyl peroxide (based on monomer) as catalyst.  The polymerization may be a bulk, emulsion or granular process, and may include benzoyl peroxide as additional catalyst.  In examples monomer and catalyst are added continuously and bulk and granular polymerizations (using the ammonium salt of styrene-maleic acid copolymer) are described.  The polyvinyl alcohol may be obtained by acid or alkaline hydrolysis or by re-esterification, and complete or partial hydrolysis may be effected.  The medium used may be aqueous, organic or a mixture thereof and the examples illustrate the use of methanol and methanolic sodium hydroxide. The products may be used in the preparation of dispersions and emulsions, in the formation of fibres, ribbons and foils, and may act as thickening agents in textile, pharmaceutical and cosmetic industries.  Specification 462,165, [Group IV], is referred to.

A resilient steel safety razor blade 30 has a rigid backing 31 of brass or other non . rusting material which is connected to the blade at a relatively few points so as not to interfere with its flexibility, and there is a space between the rear of the blade and the backing. The blade-gripping arms 32, which are preferably part of the backing, may be flexible and their blade-engaging surfaces may be flat or rounded. The sides of the blade have guard projections 36. The blade is inserted laterally into a holder 2, which contacts only with the backing and arms 32 and consists of a single piece of springy metal having a forward part 47 fitting over the bevelled ends of the arms 32 and preventing forward withdrawal of the blade in any position. A spring tongue 52 is struck up from the holder and is formed into parts 49, 50 gripping the backing, the part 50 having a lip 51 against which the backing is pressed by the spring tongue. For releasing the blade, the holder can swing about a fixed rod 53 having a rounded and a flat part so that in the release position the gripping parts 49, 50 are spread apart. The blade is then laterally withdrawn and, to facilitate this, the corners of the backing and arms 32 are rounded. Sharpening-means and mounting therefor are described in Specification 313,048.

Title: Improvements in and relating to methods of producing artificial masses
IPC: C08G12/22
Filed: 1934-12-03
Abstract: Artificial resins are prepared by condensing formaldehyde with dicarboxylic acid amides of hydrazine, its substitution products or with the monothio-derivatives of these compounds and, if desired, in the presence of acid or alkaline catalysts.  The products may be blended with resins derived from urea or thiourea and formaldehyde and may be used in the manufacture of lacquers and for impregnating wood and paper.  The resins, with or without the addition of other resins, may also be used in the treatment of fabrics to produce various effects including stiffening, anti-creasing, and elastic finishes.  In these treatments the resin, or mixture of resins, may be produced in the presence of the fibres.  In examples: (1) hydrazodicarboxyl amide is condensed with formaldehyde in the presence of sulphuric acid or caustic soda and the neutralized product is made slightly acid and hardened with or without the addition of a resin described in Specification 439,270; (4) viscose artificial silk cr<\>zepe-de-chine or a mercerized cotton fabric is impregnated with a solution containing hydrazodicarboxylamide, urea, formaldehyde and formic acid preferably also containing, when the cotton fabric is treated, the substance known under the Registered Trade Mark "Leowil," and the fabric squeezed, dried and heated to yield a fabric with a soft elastic finish; (5) viscose artificial silk cr<\>zepe-de-chine is impregnated by a solution prepared by acidulating with formic acid a solution prepared from hydrazine hydrate, urea, formaldehyde and caustic soda and finished as in example 4; (6) viscose artificial silk cr<\>zepe-de-chine is impregnated with a solution containing hydrazine hydrate, thiourea, formaldehyde and caustic soda and finished as in example 4.
