Abstract: 1,073,352. Woodworking. ARNOLDS (LOUGHBOROUGH) Ltd. March 15, 1965 [April 7, 1964], No. 14211/64. Heading B5L. A method of forming picture frame moulding comprises forming a recess in a preformed member, coating the member with material to provide a finish thereto so that the material coats the recess, and cutting the member through the material in the recess to leave the surface of the finishing material exposed in the recess. The preformed member 1 is formed with two recesses 2 and is coated with a finishing material 3, such as cellulose, shellac, paint or china clay and animal glue applied from a metal die. The member is then cut along the dotted line 5 to produce two picture frame mouldings, the cut line extending through the coating in the recesses. In another embodiment, the recesses are combined to form a single wide groove. The coating of the recesses or groove prevents a ragged or uneven edge of coating material being formed on the finished stripping.

Title: Manufacture of new anilides
IPC: C07C233/00
Filed: 1939-05-17
Abstract: 529,400. Adipic acid anilides. HOWARD, G. F., KNIGHT, A. H., and IMPERIAL CHEMICAL INDUSTRIES, LTD. May 17, 1939, No. 14769. [Class 2 (iii)] Symmetrical anilides of the general formula where R stands for alkyl, alkoxyalkyl or cycloalkyl and contains not more than eight carbon atoms and C 6 H 4  stand for phenylene which may be substituted in one ortho position to the NR by chlorine or bromine, are prepared by acylating two molecules of a substituted aniline as above defined, with one molecule of adipic acid, dinitrating the resulting adipic di-(N-substituted anilide) and reducing to the corresponding amine. The di-acid halide of adipic acid may be used as such as the starting material for the process of the invention, or it may be generated in situ. The preferred halide is the chloride, and is prepared from adipic acid and either phosphorus trichloride or thionyl chloride. The nitration takes place readily by treatment with the theoretical amount of nitric acid in solution in sulphuric acid. Reduction is effected by heating with iron in solution in solution in a mixture of water and alcohol and a small amount of acid. In examples (1) Adipic acid, ethyl aniline and phosphorus trichloride are refluxed in toluene solution for 20 hours. The toluene is removed, the residue made alkaline, and the precipitated anilide filtered. The adipic di- (N-ethylanilide) is dissolved in sulphuric acid, and nitrated to give di-(4-nitro-1-N-ethyl anilide) which is then reduced with iron filings in the presence of aqueous hydrochloric acid butyl alcohol, to give di-(4-amino-1-N- ethylanilide) (2) adipic acid, 2-chloro-N-nbutylaniline and phosphorus trichloride are refluxed in toluene solution as before to give adipic di-(2-chloro-1-N-n-butylanilide), which is the nitrated and reduced to di-(4-amino-2- chloro-1-N-n-butylanilide) (3) N-#-ethoxyethylaniline, adipic acid and phosphorus trichloride are refluxed in toluene solution, nitrated and reduced as before to adipic di-(4-amino-1N-#- ethoxyethylanilide. (4) adipic acid, N-cyclohexylaniline and phosphorus trichloride are refluxed in toluene, nitrated and reduced to adipic acid di-(4-amino-1-N-cyclohexylanilide) (5) adipic acid, N-n-octylaniline and phosphorus trichloride are refluxed in toluene, nitrated and reduced to adipic di-(4-amino-1-N-n-octylanilide).

Abstract: 997,414. Fuel injection pumps. C.A.V. Ltd. April 5, 1962 [April 25, 1961], No. 14867/61. Heading F1A. [Also in Division G3P]. A liquid fuel pump has a rotary distributer 9 driven by the engine, a head 8 at one end of the distributer with a transversely extending bore 10, at least one plunger 11 in the bore, means such as passages 7, 14 for feeding fuel intermittently to the bore, an annular cam 13 surrounding the head to impart inward movement to the plunger as the head rotates and thereby deliver fuel through the distributer to the engine cylinder in turn, a fluid operable piston 19, a cylindrical valve member 21, a compression spring 22 between the piston and valve member, a supply passage 23 through which fuel at a pressure at least in part dependent upon the speed of the engine can enter one end of a chamber 18 to act on the valve member, a further passage 24 controlled by the valve member whereby the other end of the chamber can be placed in communication with a source of liquid under pressure and with exhaust when the pressure in the supply passage rises and falls, respectively. The supply passage 23 is connected to the outlet of a feed pump 5 having its outlet and inlet connected by a relief valve which regulates the delivery pressure in accordance with speed. With increasing speed, the valve member 21 is displaced to the left allowing fluid from passage 23 to flow through a bore 27 and a non-return valve 28 to the passage 24 and displace the piston 19 to the right, the spring 22 returning the valve member to its original position. The spring also moves the valve member to the right when the speed decreases to connect the space at the left of the piston 19 to exhaust through a port 22. Fuel is discharged to the engine cylinders in turn through the ports 16, 17. In a modification, fluid for actuating the piston 19 is supplied through a non-return valve from the oil pump of the engine.
Patent GB-981268-A (GB)
Title: Organo-trifluorosilane complexes
Inventor: MULLER RICHARD
IPC: C07F7/12
Filed: 1963-04-16
Abstract: The invention comprises complex salts of organo-trifluorosilanes and alkali metal or ammonium fluorides. They are prepared by the action of the organotrifluorsilanes on the alkali metal or ammonium fluoride in solid form or in solution-a neutral or weakly alkaline aqueous solution being advantageous. The trifluorosilanes may be liberated from the dry complex salts, or their solutions, by the action of heat, or, preferably, by acidification. When hydrofluoric acid is used for the acidification, the solution may be neutralized with a suitable hydroxide and recycled.  Only trifluorosilanes and silicon tetrafluoride are thus absorbed, and the latter is not regenerated by acidification, so that the process of absorption and regeneration provides a convenient method for the separation and purification of organotrifluorosilanes. The dry complex salts are stable, and may be used for storage of the trifluorosilanes. The fluorides used are also fluorinating agents, so that it is possible to carry out processes of fluorination and purification in one step, excess fluoride acting as buffer for any acid formed. The examples describe the preparation of complexes of methyl - and phenyl - trifluorosilane with ammonium and potassium fluorides, in solution, and their decomposition by acidification, and by heat (Example 5).  Examples 2-4 describe the purification of methyl trifluorsilane by complexing with ammonium fluoride and subsequent regeneration, and Examples 9 and 10 the purification of dimethyl difluorosilane by the removal of trifluorosilane impurities. In the latter case and in Example 4 the ammonium fluoride is also used to fluorinate the initial mixtures of chlorosilanes and chlorosiloxanes.  Examples 11 and 12 describe respectively the decomposition of dry disodium methyl pentafluorosilicate and the re-use of a complexing solution acidified with HF, after neutralizing it with ammonia.

Heading D1L. In applying finishing liquid to a bundle of polyamidic or like filaments said bundle is guided progressively along a given path and a stream of pressurized gas is caused to carry with it the liquid in finely dispersed form and to impinge on said bundle to space the filaments and uniformly distribute the finishing liquid throughout the bundle. In the apparatus shown 10 is a source of compressed air or steam, 11 is a tube connecting the supply 10 to a nozzle 12, 18 is a reservoir containing finishing liquid and 13 a tube connected to the reservoir 18 and which carries the liquid to the immediate vicinity of nozzle 12. Yarn 19 to be treated is conveyed across opening 16 in vacuum conduit 17 in line with nozzle 12. In operation gas issuing from nozzle 12 creates a vacuum and lifts the treatment liquid to the outlet of tube 13. The rapid air current produces an atomizing effect and conveys the liquid on to the yarn 19. A non-metallic pin 15 is arranged in such a manner that the yarn is carried thereagainst by the gas stream thus causing the filaments of the yarn to separate and the liquid to be deposited uniformly.
