Title: Method of and means for covering tubes with plastic
IPC: B32B15/08
Filed: 1954-09-09
Abstract: 772,059. Covering tubes with resilient tubing. BURN, L. A. Sept. 6, 1955 [Sept. 9, 1954], No. 26114/54. Class 108(3). A method of covering a metal tube 18 with polyvinyl chloride tubing 17, comprises inserting a tapered plug 19 into one end of the tube 18, applying one end of the tubing 17 to the plug 19, supplying compressed air to the other end of the tubing 17, sliding the first end of the tubing 17 axially over the tube 18 while controlling the escape of air from the first end of the tubing 17, and finally cutting off the air supply. In the construction shown, the tubing 17 is continuous with a supply reel 21, the air being supplied by a pipe 22 via the bearing of the reel 21. The other end of the pipe 22 is connected to an air supply line 22a via a foot-operated valve 23 which also controls the supply of air to a device 24. The latter comprises a piston, Fig. 4 (not shown) which is adapted to close the tube 17 after the required length has been fed onto the tube 18, and has been cut-off from the main supply of tubing 17. This is to prevent air escaping from the severed end of the tubing 17. The plug 19 may comprise a cutter, Fig. 3 (not shown) for severing the tube 17. Control of the escape of air from the open end of the tubing 17 may be controlled manually, but as shown in Fig. 5, the end of the tube 17 is secured by a clamp 34 to a block 32 slidable on the tube 18. Escape of air between the tubing 17 and the tube 18 is controlled by pressure applied to a rubber annulus 36 by an adjustable screwed collar 35. As shown in Fig. 2, the tube 18 is supported by a plug 11 which may have a spigot portion, Fig. 6 (not shown), the diameter of which is equal to the diameter of the tube 18. This permits the block 32 to be drawn over the whole length of the tube 18. An adjustable limit stop is provided. As applied to the covering of conduits connected by elbows or junction boxes, the latter may be sprayed with the polyvinyl chloride to provide a continuous coating. Tubular furniture or conduit may be covered by a series of lengths of tubing of different colour, bonded together at their joints. The air pressure used may vary between 50 and 200 lbs. /sq. inch.

Abstract: 504,920. Cigarette-making machines. BELL, A., and INDUSTRIAL MACHINERY CO., Ltd. Sept. 28, 1937, No. 26213. [Class 130] [Also in Group VIII] A web, e.g. of cork for tipping cigarettes, is cut into sections by co-operating cutters 7, 8 carried by a mounting 5, 6 rockable about a spindle 10 so that the cutters move with the web, and adjustable about a vertical axis so as to alter the angle at which the web is cut. The lower part 6 of the mounting is connected to a saddle 9 on the spindle 10 by a spigot 13 and is angularly adjustable thereabout by screws 16. The upper part 5 of the mounting with the cutter 7 is reciprocated by an adjustable crank device 24 provided with self-aligning ball bearings 26 and serving also to rock the whole mounting about the spindle 10. The cutters are adjustable by screws 29, 31. In a modification, the cutters are mounted on bladÚ springs.

Abstract: 634,885. Nailing. ADLER, A., and ADLER, R. Sept. 29, 1947, No. 26244. Convention date, Nov. 7, 1946. [Class 89 (iii)] In a nailing device in which lengths are cut from a wire or strip supported in a housing 3 and are driven by a spring-operated driver 39, a spring-controlled hand lever 15 operates, through a link 21 and pin 20 and slot 22, a slidable cutter 6 co-operating with a fixed cutter 7 to sever a length of wire and at the same time, through an arm 17 and block 23, withdraws the driver 39 against springs 25 (not shown) and a wire feed-block 26 against a spring 31. When the arm 17 moves past a spring-raised pawl 23a, the driver is shot by its springs and the feedblock 26 is moved forward by its spring 31 to feed the wire, which is gripped by a spring- pressed ball 36, up to an adjustable stop 10. The device may be mechanically or pneumatically operated.

Title: Process for the preparation of derivatives of etiocholanic acid
IPC: C07J75/00
Filed: 1953-09-24
Abstract: The invention comprises compounds having the formul : <FORM:0774083/IV(b)/1> wherein R1 represents an acyl residue and R2 a hydrocarbon residue, and the preparation of derivatives of etiocholanic acid by means of the oxidation of pregnane compounds characterized in that 3b -acyloxy 14b ,21-dihydroxy pregnane - 11,20 - dione is oxidized to the corresponding etiocholanic acid derivative, after which the latter is esterified or, if desired, first saponified, and then the carboxyl group in 17-position and the hydroxyl group in 3-position are esterified and subsequently the resulting 3b -acyloxy - 14b  - hydroxy - 11 - keto - etiocholanic acid ester is subjected to the action of an agent capable of splitting off water to produce the corresponding D 14,15 ester and finally the double bond formed between carbon atoms 14 and 15 is hydrogenated to produce a 3b -acyloxy-11-keto-etiocholanic acid.  The oxidation step may be effected with chromic, perchloric or periodic acids. Esterification of the carboxyl group may be effected with diazomethane alkanols, diphenyl methanol, triphenyl methanol and benzyl alcohol while for esterification of the hydroxyl group in position -3 there may be used formic acid, acetic anhydride, acetyl chloride, trifluoracetic acid, propionic acid anhydride, benzoyl chloride, trimethyl acetyl chloride, phenyl propionic acid chloride and chloroformic acid benzyl ester, -methyl ester or -ethyl ester. The formation of the double bond between C-atoms 14 and 15 may be effected with the aid of phosphorus oxychloride in pyridine, hydrochloric acid or with silver or potassium acetate. Specification 774,082 is referred to.

Title: Improvements in or relating to the manufacture of photographic developing agents
IPC: G03C7/30
Filed: 1947-09-30
Abstract: A sulphur dioxide compound of p-aminodiethylaniline, as described in Specification 626,958, [Group XX], for use in colour photographic development is made by reacting p-amino-diethylamiline with sulphur dioxide in presence of approximately one molecular proportion of water.  Conveniently the reaction is effected in an organic solvent medium such as diethyl ether or ethyl acetate, in which the water can be dissolved.  Example 1 describes the passing of sulphur dioxide gas into ethyl acetate with external cooling to form a solution thereof, addition of this solution to one of p-amino-diethylaniline in ethyl acetate containing the required quantity of water, and filtration and washing of the precipitated product.  In example 2 sulphur dioxide gas is bubbled through p-amino-diethylaniline cotaining water, with ice cooling, to produce a thick paste, which is extracted with diethyl ether to remove any remaining free base and then washed and dried.  The Provisional Specification states that the process may be applied to the production of sulphur dioxide compounds of other aromatic amines, in particular those described in Specification 629,558, [Group XX].

Abstract: 370,334. Testing strength of pipes. SCHLOEMANN AKT. - GES., 13, Steinstrasse, Dusseldorf, Germany. Sept. 23, 1931, No. 26545. Convention date, Oct. 11, 1930. [Class 106 (ii).] A transmitting piston is introduced between the pressure water plant and the testing members so as to separate the pure pressure water from the crude filling water and thus economize the former. The pipe 3 to be tested is clamped between a piston 2 and a traverse 4 which is connected bv rods 5 to the cylinder 1. The pressure system comprises a tank 6, pump 7 and accumulator 8. The transmitting piston 17 is located with one end in a cylinder 16 and the other end in a cylinder 14. In use, pressure liquid, water and glycerine is introduced through the pipe 19 to the cylinder 1 and the pipe 3 clamped in position for testing. The valve 11 is now operated to allow crude water from the tank 10 to pass through the non-return valve 12 and through the piston 2 into the pipe 3. Crude water also passes through the non-return valve 13 into the cylinder 14. The valve system 15 is now operated to admit pressure water to the piston 17 whereupon the loaded valve 18 is opened and the valve 12 closed, the pipe 3 being placed under test pressure. After the test the pure pressure water is returned to the tank 6 under the sinking weight of the piston 17, while release of the pipe 3 is accomplished by allowing the pressure water from the cylinder 1 to return through the pipe 19 by manipulating the valve 9.
