Title: Improvements in automatic turret lathes
IPC: B23Q5/34
Filed: 1932-06-24
Abstract: 403,131. Lathes. BROWN & WARD (TOOLS), Ltd., and KENDALL, F. W., Tyburn Road, Birmingham. June 24, 1932, No. 17832. [Classes'83 (ii) and 83 (iii).] In an automatic turret lathe in which the turret is oscillated to move a number of tools between the operative and inoperative positions, the turret carries a spindle geared to a second spindle which is automatically rocked to oscillate the turret through the required angle. The turret 2 is rotatably mounted by a ball bearing 9, Fig. 1, on the lathe slide 1 and carries a hollow spindle 10 connected by skew gearing to a spindle 12 journalled in an outer casing 11 on the slide. The spindle 12 is rotated, for oscillating the turret, by a pinion 17 thereon engaging a rack-rod 15 moved vertically by a lever 28, Fig. 3, which is oscillated by cams 18 on a drum 3- engaging a roller 27 on the lever. The turret is indexed by a spring bolt 20, Fig. 1, which is released when the turret slide is retracted, by means of a cam 22 on a shaft 23 carrying an arm 24 engaging a fixed but adjustable cam 25, a spring 30 attached to a further arm 31 on the shaft 23 serving to maintain the cam 22 in contact with the upper edge of a slot 26 in the bolt 20 when the slide 1 advances. Cams 5, Fig. 4, adjustably secured to T-slots 4 on the drum 3 coact with a roller 5a on the slide 1 for reciprocating it and the roller is adjustably secured to the slide by a slot 6, bolt 7 and adjusting nut 8 to vary the position of the slide on the lathe bed. Two tool-holders such as 32 are provided radially on the turret, to be brought alternatively into operative position when the turret is oscillated through 90‹. In a modification, to allow a self-opening screwing die-head to be used without stopping the rotation of the work spindle of the lathe, the die-head is rotated in the same direction as the work and at half its speed. For this purpose, the headstock spindle 34, Fig. 4, is connected by a chain 35 to a shaft 33 rotatable within the turret casing 11 and splined to skew gearing 33a which drives a vertical shaft 36 within the turret spindle 10. The lower end of the shaft 36 drives the die-head through bevel gearing 37. Aluminium turrets.-The turret 2 may be formed of aluminium to reduce its weight.

Patent GB-1391705-A (GB)
Title: Process for desilvering used bleach fix baths
IPC: G03C5/395
Filed: 1972-04-19
Abstract: 1391705 Electrolytically desilvering used bleach fix baths AGFA-GEVAERT A G 19 April 1972 [8 July 1971] 18024/72 Heading C7B Silver is electrolytically deposited from a photographic bleach fix bath which has been used in the processing of colour photographic silver halide recording materials. Bleach fix baths contain in addition to the usual fixing agent a bleaching agent and have the function of oxidizing the metallic silver (bleaching) and dissolving the slightly soluble silver salts of the photographic recording material. In the electro-deposition of the silver, the electrolysis is carried out in a cell wherein the cathode and anode chambers are separated by a diaphragm with the exclusion of air from the cell, the silver being deposited at the cathode. The bleach fix bath is removed from the cell while the current is still running. The bleaching agent may be reduced chemically before electrolysis is carried out. As shown, cell 1 comprises anode and cathode chambers 2 and 3 separated by a diaphragm 4. In a continuous flow method of operation, used bleach fix bath is fed to a cathode storage vessel 16 and is circulated between this vessel and the cathode chamber by a pump 23. Sodium dithionite reducing agent is added continuously to the used bleach fix bath. Liquid passes slowly through the diaphragm to the anode chamber and is circulated between this chamber and an anolyte storage vessel 17 by a pump 24. Thus, the used bath is electrolytically de-silvered at the cathode 6, passes through the diaphragm and the reduced bleach is oxidized in the anode chamber. Oxidation may be completed by atmospheric oxygen. Regenerated liquid, to which regenerator additions may be made is removed at 26. To ensure that there is no flow through the diaphragm from anode to cathode, the level of liquid in vessel 16 is higher than in vessel 17, this being ensured by feeding the used bleach fix bath to the vessel 16 such that there is some overflow 25. For removal of deposited silver from the cathode, the apparatus is dismantled. A batch method of operation is also described wherein batches of electrolysed liquid are removed from the cell through taps 20. In the Examples, a bleach fix bath contains ethylenediaminotetraacetic acid, iron-III complex thereof, sodium sulphite, tertiary sodium phosphate sodium thiosulphate and ammonium thiosulphate. The used bath contains AgBr.
Patent GB-498038-A (GB)
Title: Improvements in and relating to lathes and like machine tools having indexible turrets
IPC: B23Q16/06
Filed: 1937-06-29
Abstract: 498,038. Lathes. TRIGGS, W. W. (Warner & Swasey Co.) June 29, 1937. No. 18043. [Class 83 (iii)] An indexible tool turret for a lathe or like machine tool adapted to be mounted on a cross slide and indexed, locked, and clamped, comprises a contractible clamping ring having arms 46a, 46b, Fig. 8, extending towards the front of the cross slide, and a manual control means 57 located adjacent the front end of the cross slide and operatively connected with said arms for clamping and unclamping the indexible turret. The handle 57 also controls a locking pin and may also effect the indexing operation, alternatively, the latter may be effected by turning the tool turret 42, Fig. 7, by hand. Where indexing is automatic, a connecting link transmits movements of a disc connected to the handle to a toothed sector 50 which meshes with a toothed collar 49, Figs. 8 and 13, carrying a spring-pressed catch 48 and freely rotatable about the turret axis. Movement of the control handle to the dotted position in Fig. 8 moves the roller 55a, which normally turns against the heel portion of the lever 58 to apply the clamping ring, to its inoperative position ; at the same time the toothed sector 50 is rotated and a cam portion 50b thereon rocks a lever 51, Fig. 10, to withdraw the turret locking plunger 52. Further movement of the handle rotates the collar 49 with the catch 48 and this engages with ratchet slots 45d, Fig. 13, in the underside of a collar fixed to the turret, to rotate the latter through 90 degrees, a spring-pressed plunger 47 engaging notches in the periphery of the collar to hold the turret until the return locking and clamping movement of the lever 57 is effected. Double ratchet mechanism is described permitting automatic indexing of the turret in either direction of rotation.

Patent GB-477451-A (GB)
Title: Improvements in metallic pigment pastes
IPC: C09D5/10
Filed: 1936-06-30
Abstract: Metallic pigment pastes, for use in the production of paints, containing leafing metallic particles and a thinner which is innocuous to the leafing property, are improved by the incorporation of an amount of leafing agent in addition to that which is normally provided for the leafing process.  The leafing stability of the paste, under adverse conditions of storage or use, is thereby increased.  Stearic and/or palmitic acid is the preferred leafing agent used, and the excess of leafing agent incorporated is preferably about 1 per cent of the weight of the metal.  In a preferred method, the paste is formed by simultaneous flaking and leafing of the metal by impact grinding in a ball mill, in the presence of a thinner and a leafing agent, the product being washed and filtered to form a relatively dry filter cake which is then formed into a paste with a thinner and the excess leafing agent. Specified metals are aluminium, copper, brass, tin and zinc, and specified thinners are varnolene, xylol, toluol and hydrogenated naphtha.  Specification 391,839 is referred to.

Abstract: 300,166. Ruth-Aldo Co., Inc., (Assignees of Klein, M.). Nov. 7, 1927, [Convention date]. Addition to 292,561 and 292,608. Apparatus for making filaments.-The apparatus for the dry spinning of solutions of cellulose esters and ethers described in the parent Specifications is modified so that each zone of the spinning cell is provided with orifices for the admission and discharge of air, the circulation of which in any zone is independent of the circulation in the other zones. The air with or without solvent vapour discharged from any zone may, however, be passed subsequently through any of the other zones and may be treated at any stage in order to modify its temperature or the concentration of the solvent vapour or in order to add to the air, vapours or gases, which exert physical or chemical action on the thread. In the drawings A - - D represents the spinning cell F the spinning nozzle; H the thread; I a thread guide, and G the orifice through which the thread passes out of the cell. In the apparatus shown in Fig. 1, the cell is divided into two superimposed zones by the diaphragm M, N, which is fitted with an orifice Z for the passage of the thread. The upper zone is provided with orifices E for the admission of cold air about the nozzles and an aspiration orifice J, whilst the lower zone is fitted with orifices K for the admission of hot air and aspiration orifices L. In the form shown in Fig. 2, aspiration of the cold air entering the upper zone is effected through the tube J<1>, which rests on an oblique diaphragm MN, so that its mouth J<2> is situated at a suitable distance from the thread, whilst the circulation of air in the lower zone is effected as described above. In another modification, the cold air leaving the upper zone passes through a heating apparatus V, Fig 3, of any type to the lower zone and is aspirated laden with solvent vapours through the orifice L. In the form shown in Fig. 4, the heated air leaving the lower zone passes through a cooler V of any type to the top zone and is aspirated through the orifice J, whilst in the further modification shown in Fig. 5, the air circulation is the same as that in the apparatus shown in Fig. 3, except that a fluid, gas or vapour is introduced through tube X into the branch X<1>, where it mixes with air prior to its entry into the lower zone.

Title: Improvements in or relating to polymerization system
IPC: C08F2/00
Filed: 1955-06-24
Abstract: <PICT:0770265/IV(a)/1> Catalyst efficiency is controlled in a continuous process for the polymerization of isobutylene alone or with isoprene, butadiene, piperylene, a -methylpentadiene, a -methyl styrene, indene or vinyl napththalene to incomplete conversion, in which the reactants are mixed with a volatile diluent, e.g. methyl chloride, cooled to 10 to - 160 DEG  F. and contacted with a Friedel-Crafts catalyst dissolved in the diluent, after which the diluent and unreacted materials are flashed off, compressed, dried and passed to a series of distillation towers from the first of which a high purity fraction of the diluent is taken overhead, condensed and used as a solvent for fresh catalyst, and the bottoms fraction is passed to a second distillation tower from which the remainder and main portion of the diluent is taken overhead for recycling to the polymerization zone.  The improvement is obtained by automatically diverting the excess flow of the compressed, flashed materials above a predetermined amount away from the first tower and passing it to the midpoint of the second tower and conversely in the case of deficiency, automatically drawing the required amount from the overhead from the second tower, whereby a substantially constant flow of material is maintained to the first tower.  In an example recycle tower feed from the copolymerization of isobutylene and isoprene in a methyl chloride solvent to 60 per cent conversion is passed to distillate tower A, from which the overhead is passed to a condenser 3, a separator 4 and a solvent storage tank C, from whence it is withdrawn through a temperature regulator 8 and part is passed directly to a catalyst solution supply tank D and part circulated through aluminium chloride in container E and passed to D.  A uniform volume flow into tower A is maintained by a flow recorder controller E in the tower A feed line connected with a split range controller F operating a flow recorder controller valve G to by-pass excess feed to tower A into the intermediate point of tower B or by flow recorder valve H to withdraw overhead from tower B to make up any deficiency in the feed to tower A.
