Lacquers.-Non-blushing solutions of nitrated carbohydrates (nitrocellulose, nitro-starch, &c.) are obtained by using only solvents which are immiscible with water. Volatile diluents if used must also be water-insoluble. It is unnecessary completely to dehydrate the nitrocellulose before solution. The solutions may contain other ingredients such as gums, oils, pigments, &c. to adapt it to the purpose of a lacquer, &c. An example of a lacquer comprises nitrocellulose, butyl acetate, toluol, ester gum, and tricresyl phosphate. Other solvents mentioned are amyl acetate, butyl propionate; other diluents are xylol, mineral spirits, turpentine. Specification 293,435 is referred to.

Filed: 1927-10-26
Abstract: 299,190. Howard & Bullough, Ltd., and Airey, E. J. Oct. 26, 1927. Yarns, warping and beaming.-In an improvement of the devices described in Specification 214,925 for controlling the friction driving devices for use in the beaming operations in sizing machines &c., the forked pressure lever w for controlling the friction discs x carries a bowl &c v acted upon by a curved member u rigidly connected to the movable pivot t of a weight lever s. This pivot is carried by one end of a lever o, the opposite end of which is acted upon by a catch p pivoted on a square rod m connected by lever mechanism &c. to the presser shaft d, so that as the beam fills the rod m is lowered, the lever o turned, and the parts t, u, s raised to change the leverage with which the member u acts and thus vary the pressure transmitted to the friction discs. A peg or stop q adjustably secured to the frame limits the downward movement of the lever o under the catch p by tripping the latter and turning it on its pivot A safety catch comprising a curved rack 1 pivoted at 2 to the lever o may be moved into engagement with a toothed part 3 to hold the pressure device at any position reached and thus maintaining the pressure at the friction discs constant during a period, for example, whilst the machine is stopped. The lever s may be moved over to the left for doffing a full beam &c., a projection t<1> striking a part 4 of the rack 1 and releasing this from the part 3.

Fig. 1 shows an S-form lever 5 with one end pivoted at 10 to the limb 3 and having a serrated &c. cam surface 7 adapted to co-operate with a preferably smooth surface 4 on the upper limb 2 which forms the fixed jaw. The free end of the lever has an offset portion 8 ending in a thumb-piece 9 situated at one side or the other of the body, depending on whether the clip is for use with the right hand or the left. The lever is urged towards the gripping position by a spring 13. The lower limb may have lateral extensions 6 to prevent lateral tilting of the device in use. Modifications are described in which the clip is formed from sheet-metal blanks, and in which the portion 8 of the lever is not laterally offset, but is centrally disposed and passes through an aperture in the upper limb. The lever, or the working surfaces of the two jaws, may be removable for renewal. Fig. 4 shows a form in which the body of the clip is formed from a single blank with webs 26 connecting the upper and lower limbs and the lever, formed from, another blank, has its free end 9<a> passed up through an aperture in the upper limb. The co-operating surfaces 4<a>, 7<a> are on separate removable members held in place by bent-over lugs.

Title: Improvements in or relating to composite materials of polyvinyl halide and solid backing materials, and methods of making the same
IPC: B32B15/08
Filed: 1937-10-21
Abstract: Polyvinyl halide layers are caused to adhere to solid backing materials, e.g. metals, by interposing a layer of halogenated rubber. The halogenated rubber is applied as a cement and the polyvinyl halide either as a solution or as a preformed sheet, or both. Resinous material, e.g. ester gum, may be added to the chlorinated rubber.  In an example, an iron surface is sandblasted, three coats of a solution of 100 parts of chlorinated rubber in 570 parts of mesityl oxide are applied, and then three coats of a solution of 100 parts of polyvinyl chloride, plasticized with 25 parts of tricresyl phosphate in 875 parts of mesityl oxide.  The adhesion is improved by baking in an oven at 70 DEG  C.  A preformed sheet of polyvinyl chloride may be applied to the polyvinyl chloride film and caused to adhere by heat and pressure or by using an adhesive of polyvinyl chloride solution. In another example a sheet of polyvinyl chloride is combined with an iron backing by coating both sheets with chlorinated rubber cement, allowing to dry, and then causing the two sheets to adhere by another layer of chlorinated rubber cement.  In a modification of the invention, a coat of chlorinated rubber is applied to metal followed by coats of mixtures of chlorinated rubber and polyvinyl chloride in which the quantity of chlorinated rubber is successively reduced until none is present.
