Title: Improvements in and relating to surface coatings of soft to hard rubber or the like
IPC: B29C63/00
Filed: 1935-03-01
Abstract: 453,123. Lining pipes. WILDERMAN, M., Villa Meurice, Rue Bosio, Monaco, and WILDERMAN, P., 4, Chartfield Avenue, Putney Hill, London. March 1, 1935, No. 6476. [Class 99 (ii)] [See also Groups V and XVII] The invention relates to the method of lining hollow articles such as pipes with rubber &c. by introducing into the articles a perforated hollow core covered with a continuous layer of the lining material, exhausting the air from the space between the article and the core, and inflating the material by admitting air or other fluid to the core to transfer it to the internal surface of the article. According to the present invention, the inflation is conducted in such a way that it commences in a restricted area so that contact between the material and the inner walls of the article is established at first over a restricted area only and is continued so that the deposition is continued from this initial place of contact towards the open end or ends of the article, pushing thereby any residual air before the inflating rubber towards the end or ends of the article. The pressure of any residual air in the space between the inflating material and the article is prevented from increasing unduly during the inflation by connecting this space with exhausting means or with the outer atmosphere. The initial inflation of the rubber over a restricted area may be effected by perforating the core over a restricted area only and by heating the rubber so that it is at a relatively higher temperature over a restricted area. Fig. 4 shows apparatus for the lining of a pipe 22 open at both ends. The ends of the article are held in end-caps 1 by gasket joints 3, 5 and the perforated core 14 carrying the lining material is held in the caps 1 by gasket joints 2, 4. The core 14 is provided with perforations 16 over a restricted area only. The space between the core and the pipe 22 is exhausted through pipes 10, air being exhausted from and inflating fluid supplied to the core through a pipe 23. The lining material may be heated before, during or after the inflation. Fig. 5 shows apparatus for the lining of an article 22 open at one end only ; in this case the perforations 16 are arranged at the end of the core adjacent the closed end of the article and a heating coil 18 is arranged within the core to give a relatively greater heating in the same area. Specification 374,842 is referred to.

Title: Improved process for the emulsification of tars and like substances
IPC: C08L95/00
Filed: 1938-03-02
Abstract: 506,300. Bituminous emulsions. WOODALL - DUCKHAM (1920), Ltd., and ARNOLD, E. March 2, 1938, No. 6514. Addition to 465,589. [Class 1 (i)] In the process described in the parent Specification wherein a water-in-oil emulsion is first made from the whole of the tar, pitch, or bitumen, &c., and a part of the water and an emulsifying agent, and this emulsion is then reversed by dispersion in a concentrated aqueous solution of an emulsifying agent, the emulsifying agent employed for the preparation of the water-in-oil emulsion consists of a solution containing farinaceous matter, e.g. starch, and an alkali or alkaline salt, e.g. caustic soda or trisodium phosphate or a mixture of such a solution with an alkali alginate, and the emulsifying agent used for reversing the water-in-oil emulsion consists of an alkalisoluble protein and a small amount of free alkali together with either an alkaline farinaceous solution or a mixture of such a solution and an alkali alginate. The viscosity of the final emulsion may be increased by decreasing the amount of water used in the first stage, and conversely, and the rate of breaking may bedecreased by increasing the proportion of alkali alginate used in the second or both stages, and conversely. The use of trisodium phosphate tends to increase stability. Formaldehyde may be added as a preservative. According to examples: (1) a water-in-oil emulsion of road tar is obtained with the aid of a starch solution containing either caustic soda or trisodium phosphate and a little formaldehyde. This emulsion is then reversed by stirring into a solution containing starch, casein and ammonia. The product may be diluted as required ; (2) an emulsion of road tar is prepared using a starch solution as above, and sodium alginate in the first stage and starch solution, sodium alginate, casein and ammonia in the second stage. This emulsion 'breaks less rapidly than that described in example 1 ; (3) an emulsion of coke-oven tar is made using starch solution containing trisodium phosphate and a little formaldehyde. In this case, it is necessary to use sodium alginate in addition to starch, casein and alkali in the second stage.

Patent GB-312969-A (GB)
Title: Improvements in or relating to wrapping machines, labelling apparatus, or the like
IPC: B65B57/12
Filed: 1928-03-02
Abstract: 312,969. Rose, W., and Rose Bros. (Gainsborough), Ltd. March 2, 1928. Packeting by wrapping-up. - In machines in which a succession of caramels, tablets, boxes, or other articles are fed up to a station at which they are thrust one at a time into wrapping, labelling, packing, or like machine, means are provided for stopping the wrapper or label feed in the event of an interruption of the supply of articles. The means comprise a clutch in operative connection with a detector mounted on a carrier for reciprocation to and from the charging station and movable in relation to the carrier for controlling the clutch. As shown, the articles 22, Fig. 11, are brought by a conveyer chain 41 into position between a reciprocating plunger 18 and a pocket formed by sides 11, 12 mounted in a wrapping wheel 10. The plunger advances and thrusts each article into the pocket, carrying with it a wrapper 21 fed by rollers 26, 27 and severed by a knife 23. The mechanism for detecting the presence or absence of an article and for controlling the feed of wrapping material accordingly comprises a pin 40, Fig. 3, extending through a bore in the plunger 18. In the event of an article being present in the path of the plunger, the pin is moved backwards relatively to the plunger and rotates a bell-crank lever 43 to move a rod 44 at right angles to the path of the plunger. This causes a pawl 46, Fig. 3, to come within the path of a detent 47, Figs. 3, 4 and 6, carried on one arm 48 of a three-armed lever 48 - - 50. The continued movement of the plunger, carrying with it the pawl in its extended position, rotates the detent 47, within the limits allowed by a pin and slot device 61, in a clockwise direction. The three-armed lever 48 - - 50 is oscillated in timed relationship with the plunger, and the detent having been rotated, an extension thereof 63 engages a fixed stop 65 and prevents a clutch throw-out device from operating. If no article is present, the pin 40 does not cause the detent to be rotated so that the extension 63 escapes the stop 65 as shown in Fig. 4 and allows the lever 48 to make a full movement, with the result that a roller 56, Figs. 5 and 6, is brought into engagement with a face cam 57 and disengages clutch members 30, 31 to arrest the feed of wrapping material. A rod 71 resets the pin 40 in position after each stroke and a stop 64 rotates the detent back into position at each reverse movement of the lever 48. If no article is present and the pin 40 engages the base 90, Fig. 11, of the pocket in the wrapping wheel, and causes the pawl to be advanced, it is by then clear of the detent and no interaction takes place.

Abstract: 1,120,872. Production of staple fibres from films. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 14 Feb., 1967 [16 Feb., 1966], No. 6928/67. Heading B5B. Staple fibres are produced by cutting in the lateral direction a strip of highly crystalline thermoplastic film which has been stretched in the longitudinal direction (at a stretching ratio sufficiently high, having regard to the stretching temperature, to render the film fibrillatable) to form clippings, the dimension of each clipping in the direction parallel to the longitudinal axis of the film being equal to the length of the largest of the staple fibres to be obtained from that particular clipping which clippings are subsequently fibrillated to form staple fibres. The clippings may have the same dimensions. The largest dimension of the clippings may be parallel to the direction of stretch of the film. The stretched film strip may be crimped before being cut into clippings. The clippings may be fibrillated in a carding machine. The film strip may be brought into the form of a fibrous strand by twisting before being out into clippings. The clippings may be out from a number of film strips situated next to one another and obtained by cutting a wide extruded film web longitudinally into film strips of the same width. The dimension of the clippings in a direction parallel to the direction of stretch of the film may be 20 to 60 mm. A particularly suitable film material is highly crystalline polypropylene or high density polyethylene. The width of the film strips is generally 5 to 25 mm., preferably about 15 mm. The stretching ratio is in general between 7:1 and 15 : 1, preferably about 10 : 1.
