Abstract: 967,205. Inverting. ALSTHOM SOC. GENERALE DE CONSTRUCTIONS ELECTRIQUES ET MECANIQUES. Feb. 7, 1962 [Feb. 7, 1961], No. 4804/62. Heading H2F. Each semi-conductor controlled rectifier (SCR) (for example In), of an inverting arrangement has connected in series with it a winding 6n inductively coupled to another winding 6p which is connected in series with a rectifier 1p passing current in antiphase to the current in the first rectifier In. In the Figure a star-connected transformer winding 1, 2, 3 supplies a bridge of six SCR's In, 2n, 3n, 1p, 2p and 3p through such windings. Alternatively a sixphase double star arrangement may be used (Figs. 5 and 6, not shown). The pairs of windings may be coupled indirectly, using two transformers and an intermediate circuit for each pair (Fig. 7, not shown). In a conventional arrangement one rectifier (for example In) would be subjected to a suddenly increased forward voltage when in the forward blocking state, which could cause premature firing, during the commutation period of two other rectifiers in this case 2p and 3p) (Fig. 2, not shown). This is due to the circulating current between the supply phases during the commutation period. In an arrangement according to the invention this circulating current flowing through winding 6p induces in winding 6n a voltage which opposes the change in voltage to which the rectifier In would otherwise be subjected. Preferably the mutual inductance of the pairs of additional windings is equal to the phase inductance of the transformer secondary windings.

Title: Improvements in or relating to multi-station tool holders for lathes and other machine tools
IPC: B23Q16/10
Filed: 1950-02-27
Abstract: 682,793. Turrets. FRANCE, H. C. Feb. 21, 1951 [Feb. 27, 1950], No. 4990/50. Class 83 (iii). A multi-station tool turret comprises a block rotatable about a vertical spindle on a base, the upper portion of which has a quick pitch thread and is engaged by a nut which is held against axial movement with respect to the block but is rotatable relative thereto, and having means by which it is constrained to move with the block after predetermined movement in one direction so that the block can be raised, rotated, and lowered to engage dogs on the base and means for preventing rotation of the block whenever it has been rotated to a new tool position so that it can be lowered into that position. A tool-carrying turret block 1 is rotatable around a vertical hollow spindle 2 having at its upper end a quick-pitch thread 17 and secured to a slide or base 5 by a pillar bolt 7 and nut 8. A collar 18 with a handle 19 for rotating it has an internally threaded sleeve 18a to engage the threads on the spindle. The collar is connected by a ring 21 to be axially held but relatively rotatable with respect to the block 1. On anticlockwise rotation of the handle the block 1 is lifted clear of dogs 10 on the base but is held against rotation by a spring-pressed locating plunger 14 which has a bevelled end face and engages slots 12 in the sleeve at the indexed positions. As the block 1 is moved axially clear of the base dogs a further spring-pressed plunger 23 engages a notch in the lower face of the collar 18 and the latter and block are then constrained to move together, the plunger 14 being forced out of its slot. With continued anticlockwise movement the plunger 14 finally engages the next slot 12 corresponding to the next tool position. The handle is then rotated clockwise to tighten the block on to the locating dogs of the base. In a modification the plunger 14 is replaced by a plunger which engages recesses in the base and which is kept out of engagement during the initial anticlockwise movement by a spring- pressed latch engaging cam surfaces on the sleeve.

Filed: 1943-03-31
Abstract: 567,375. Injection-moulding machines. SHIPTON, E., and HILL, W. N. March 31, 1943, No. 5125. [Class 87 (ii)] The hydraulic, air or other pressure cylinders 9, which impart vertical reciprocation to the injection plunger 13 via rods 10 and yoke 11, are disposed below or to the side of the bulk feed hopper 4, whereby any fluid which leaks from the cylinders cannot drip into the hopper. The cylinders are fed (by connections not shown) from a reservoir 35 by an electrically-driven pump 36 ; two pressure relief valves permit the use of two pressures in the cylinders. When the plunger 13 is at its nadir it prevents entry of plastic material from the hopper into the melting chamber 5. To prevent material falling on to the back of the plunger, a sleeve 50, of the same diameter as the plunger, surrounds the latter ; alternatively, the plunger-carrying rod 12 and the plunger may be of the same diameter and may form an integral body. A two-part hinged cover 14, 15 encloses the top of the hopper. The injection nozzles 23 have heat - insulating sleeves 24 and extend radially from the base of the melting chamber. Mouldcarrying tables 25 are vertically adjustable on the machine frame, and may carry slides to feed the moulds up to the nozzles'where the moulds are locked in position. Another table 30, bolted to the machine frame, carries a hotplate for pre-heating moulds. Cooling-water issuing from the moulds is collected in a drain tank 34. A tray 2 collects water which drips off the tables and delivers it to the tank 34. In modified, constructions : (1) there may be only one cylinder 9 which may operate the plunger 13 either by a lever arm or (when the cylinder is disposed directly below the melting chamber) by a loop-shaped yoke or a. rod passing through an opening in the bottom of the melting chamber; and (2) the melting chamber may extend upwardly through the hopper, a series of apertures in the chamber being covered and uncovered by the moving plunger.

Abstract: 1,148,572. Coarse crystals of urea. POWERGAS CORP. Ltd. 3 Feb., 1967 [5 Feb., 1966], No. 5140/66. Heading C2C. Coarse crystals of urea are obtained by crystallization from an aqueous urea solution containing 2-12% by wt. biuret and 0À1- 0-4% by wt. cyanuric acid, based on the wt. of an aqueous urea solution saturated at 60‹ C. Biuret and cyanuric acid may be added as such to the urea solution or may be added in admixture with urea, said mixture being obtained by thermal decomposition of urea at, e.g. 135-190‹ C. Crystallization may be effected by cooling and/or evaporation of water. The biuret content of the urea crystals, which is 3-5% by wt., may be reduced by washing with a saturated solution of urea. This washing liquid may be employed subsequently as the starting solution to which biuret and cyanuric acid are added. The crystallization process yields hexahedron crystals averaging 3 mm. in length and 1 mm. in width.
