Title: A device for indicating the feeding movement of a tool on a movable part of a machine tool, such as a boring or milling machine
IPC: B23Q1/00
Filed: 1946-02-27
Abstract: 627,049. Lathe details. BERTHIEZ, C. W. Feb. 27, 1946, No. 6115. Convention date, March 10. 1945. [Class 83 (iii)] In a device for indicating on a first. part of a machine-tool the movement of a tool relative to a second machine part which is itself movable relative to the first part (e.g. radial feed of a tool on a surfacing plate), an index member is fitted on an indicator slide which is actuated by the tool feed-shaft so that it moves in synchronism with the tool, the feed-shaft being connected to the tool through a differential mechanism. Rotary tool heads.-A lathe comprises a boring spindle 2, Fig. 4, and a surfacing plate 3, the latter having radial guides for a surfacing slide 6 which is fed by a nut 7 engaging a leadscrew 8. The screw is rotated by a bevelwheel 9 meshing with a gear-ring 11 rotatably mounted on the surfacing plate and driven from a hand- or motor-driven shaft 13 through a clutch 14, a shaft 12 and a differential 18. The cage of the differential has teeth engaging a gear-ring 19 fixed to the surfacing plate and the consequent rotation of the cage rotates the gear-ring 11 at the same speed as the plate so that the feed-screw is not rotated by the rotation of the plate. The indicator slide, Figs. 2 and 3, comprises an outer slide 25 sliding in ways 26 on the lathe headstock and an inner slide 24 carrying a nut 23 engaged by a screw 22 which is rotated by a worm-wheel 21 engaging worm teeth 20 formed on the clutchplate; the transmission ratio is preferably such that the surfacing and indicator slides move through equal distances. A plate 27 closes the opening which would be left by the slides in their uppermost position. The outer slide carries two scales 29 arranged with their markings reading in opposite directions and adjustable relatively to each other to compensate for play in the drive, according to the direction of movement. The slide 25 also carries two index members 28, having vernier markings so that they may be adjusted against their respective scales, and the position of the tool on the surfacing plate may be gauged by observing the position of the index members relative to a fixed point, such as a switch 30, which may be operated by the index members to stop the feed-motor when the required movement of the surface slide is completed. Feed motions.-The device may be applied to a tool-slide which is fed relative to a table moved rectilinearly.

Patent GB-654469-A (GB)
Title: Methods of recovering phthalic anhydride
Filed: 1948-02-29
Abstract: Phthalic anhydride is removed from gases or vapours containing the same by subjecting the gases or vapours while at an elevated temperature to the action of a water spray or water in the form of fine particles, whereby the phthalic anhydride is condensed and precipitated, the water being supplied in an amount sufficient to condense and precipitate a major proportion of the phthalic anhydride but not in an amount appreciably greater than that required to saturate said vapours or gases.  The temperature of the vapours may be above the condensation temperature of phthalic anhydride in the solid phase, or the temperature may be 130 DEG  C. or higher and is then reduced to 50 DEG  to 95 DEG  C. with the water.  The gases containing phthalic anhydride may be fed into the upper end of a tower, treated with the water and the precipitated phthalic anhydride removed, e.g. by allowing it to settle at the bottom of the tower and then removing it in a liquid condition by melting. The water employed in the tower may be in the form of particles that are sufficiently small to evaporate before they impinge on any portion of the tower. The phthalic anhydride vapours can be obtained from the vapour phase partial oxidation of polynuclear aromatic compounds, e.g. naphthalene, and the hot reaction gases p  are partially cooled to a temperature not lower than 130 DEG  C. before being subjected to the water treatment, e.g. by treatment in the tower mentioned above while remaining gases containing unsettled phthalic anhydride may be removed from the tower and the phthalic anhydride separated from said gases.

Patent GB-473126-A (GB)
Title: Improvements relating to the production of materials for use in preparing emulsions for the treatment of textile materials
Filed: 1936-03-02
Abstract: An emulsifiable composition for assisting the dyeing of textile fabrics and yarns, e.g. by preventing "bleeding," is obtained by mixing fats and/or oils, or the corresponding fatty acids with a high melting paraffin fraction such as ozokerite or paraffin wax and a saponifiable vegetable or animal wax, e.g. spermaceti, montan wax or wool wax and heating with a dehydrating agent, e.g. fused zinc chloride, ferric chloride or aluminium chloride until the colour becomes blackish and dark particles separate.  The clear oil is separated from the residue and is treated to saponify the fats, fatty acids and waxes present.  After cooling, the mass may be emulsified with water with the aid of a protective colloid, e.g. casein rendered soluble with boric acid and ammonia, and also a non-volatile water-soluble organic compound containing nitrogen and/or sulphur, such as hippuric acid, neurine, betaine or albuminoid products, e.g. egg-white or glue may be added.ALSO:An emulsifiable composition for preserving and waterproofing textile fabrics and yarns and assisting in the dyeing of such materials is obtained by mixing fats and/or oils, or the corresponding fatty acids with a high melting paraffin fraction such as ozokerite or paraffin wax and a saponifiable vegetable or animal wax and heating it with a dehydrating agent e.g. fused zinc chloride, ferric chloride or aluminium chloride until the colour becomes blackish and dark particles separate.  The clear oil is separated from the residue and is treated to saponify the fats, fatty acids and waxes present.

Title: Process for the preparation of n-disubstituted dithiocarbamic acid esters which contain sulphonic acid groups in the alcohol residue
Filed: 1957-02-26
Abstract: An N-disubstituted dithiocarbamic acid ester containing a sulphonic acid group in the alcohol residue, or a salt thereof, is prepared by heating a salt of an N-disubstituted dithiocarbamic acid with a salt of a halogeno-alkane sulphonic acid in accordance with the process of the parent Specification, characterized in that the reaction is carried out in an aqueous solution of an inorganic or organic salt which does not take part in the reaction, the concentration of which is so chosen that the salt of the dithiocarbamic ester formed separates on cooling in largely crystalline form.  Suitable examples of such inorganic or organic salts are the chlorides, bromides, sulphates, nitrates and acetates of sodium, potassium, calcium, magnesium, ammonium or organic bases, such as ethylamine, diethylamine and triethylamine. It is convenient for the cation of the salt to be the same as that in the desired product where the product is a salt.  Sodium chloride is preferred.  In examples: (1) diethylamine is added to a mixture of carbon disulphide and a saturated sodium chloride solution, then caustic soda solution is added, whereby sodium N-diethyldithiocarbamate is formed; sodium bromoethane-sulphonate is added and the mixture heated for 5 hours at 90-95 DEG  C. and on cooling the sodium salt of N-diethyl dithiocarbamic acid-ethyl ester-o -sulphonic acid separates out; (2) piperidine is added to a mixture of carbon disulphide and calcium chloride solution followed by a portionwise addition of aqueous caustic soda and stirring at 50 DEG  C. until the mixture becomes clear; calcium 3-bromo-propanesulphonate is added and the mixture is heated for 3 hours at 95 DEG  C. whereafter N,N-pentamethylene - 1,5 - dithiocarbamic acid - propyl ester-o -calcium sulphonate separates on standing.
