Title: Improvements in or relating to the molding of thermoplastic material
IPC: B29C48/365
Filed: 1958-01-15
Abstract: 882,931. Injection and extrusion moulding apparatus. OWENS-ILLINOIS GLASS CO. Jan. 15, 1958 [Jan. 28, 1957], No. 1378/58. Class 87(2). Apparatus for moulding thermoplastic material comprises a palsticizing chamber 11, a rotary feed screw 12, and means for recirculating the plasticized material when the outlet of the chamber 11 is sealed by axial movement of the screw 12. The apparatus may be used for injection moulding finished articles or for injection moulding a portion of an article and then extruding a portion which is subsequently blowmoulded. In the example shown in Fig. 3 the screw has an integral end sleeve 26 having a shoulder 25 adapted to engage a piston 27 which is slidably mounted on a pin 28 carried by a plate 30. When the screw 12 is rotating in its axially retracted position material is delivered under pressure through ports 37 in plate 30 to a passage 24, the piston 27 being held near the open end of sleeve 26 by the head of pin 28. By shifting screw 12 so that sleeve 26 enters passage 24, Fig. 2 (not shown), passage 24 is disconnected from chamber 11, and material is injected in to the mould 45 by means of the piston 27 and sleeve 26. The screw 12 continues rotating, recirculation of material taking place through passages 38, 39, 41 within the screw. The screw 12, sleeve 26 and piston 27 are then retracted so that material is again delivered to the passage 24 and orifice 33 to extrude a hollow formation 47, the mould 45 being simultaneously withdrawn. A hydraulically actuated plunger 42 prevents recirculation of the material in this position of the screw. The formation 47 may be severed by a blade 48 and then shaped by blow moulding. In Fig. 4 sleeve 26 and piston 27 are eliminated, injection being effected by plunger 42, and recirculation taking place through axial and radial passages 39a and 41. A stop-start valve 50 is provided, and the end of screw 12 is chamfered at 49 to be insertable against the opening of passage 24 to disconnect it from chamber 11. In Fig. 5 (not shown), the sleeve 26 and piston 27 of Fig. 1 are replaced by a solid piston on the end of the screw. Specification 882,932 is referred to.

Patent GB-900187-A (GB)
Title: Traversing device for yarn winding devices
IPC: D01H1/36
Filed: 1961-01-13
Abstract: 900,187. Converting rotary into reciprocating motion; screw-and-nut gearing. CHEMSTRAND CORPORATION. Jan. 13, 1961 [Jan. 21, 1960], No. 1595/61. Classes 80 (1) and 80 (3). [Also in Group IX] A motor 12 drives an endless toothed belt 33 that is used as a means for reciprocating a block 18 along guide-bars 17, there being a pair of gears 36, 37, freely rotatable on the block 18 such that the gear 36 meshes with the left-hand span of the belt 33 and the gear 37 meshes with the right-hand span, the gears 36, 37 being alternately locked against rotation to cause the block 18 to be reciprocated by the belt. The locking means is a lug 42 carried by a plate 43 slidably mounted on the traversing block 18. An L-shaped pin 45 having one end in the locking-lug 42 and its other end in the block 18 is surrounded by a compression-spring 46 to impart a snap-action to the plate 43. When the lug 42 is in its lower position, as shown, it locks the gear 36 against rotation and the block 18 is carried downwardly by the belt 33 until the plate 43 is forced against a lower striker-plate 50. This action forces the plate 43 upwardly and the spring 46 then causes the lug 42 to release the gear 36 and lock the gear 37, thus causing the block 18 to be raised by the righthand side of the belt until the plate 43 is forced against an upper striker plate 51. The action is then reversed. The striking plates 50, 51 are slowly moved towards each other to reduce the stroke of the block 18. For this purpose the plates 50, 51 are slidable on one of the guide-bars 17 and each plate carries a threaded finger 52, 53 spring-biased against a screw 56 threaded in opposite directions at its opposite ends and driven through a gear-box 13. To move the plates 50, 51 back to their starting positions the fingers 52, 53 are forced away from the screw 56 so that the plates 50, 51 can be moved manually along the guide-bar 17. The apparatus is used as a traversing device for a yarnwinding mechanism (see Group IX).

Title: Crude petroleum oil distillation process
IPC: C10G7/00
Filed: 1948-01-19
Abstract: <PICT:0645072/III/1> Crude petroleum oil containing salt and water is submitted to partial flash-distillation to separate steam and low-boiling hydrocarbons, the liquid heavier constituents from the flash-distillation are passed in at least two separate streams through a series of heat-exchangers which are heated by liquid fractions derived from subsequent rectification of the oil, the steam and low-boiling hydrocarbons are re-united with the thus-heated heavier constituents, and the mixture is then submitted to fractionation.  The process avoids the injurious simultaneous presence of salt and water in the system.  Crude oil containing 0.5 per cent (vol.) water and 40 lbs. salt per 1000 bbl., is pumped at a pressure of 400 lbs. per square inch into preheater 13 where it is raised to 310 DEG  F.  The preheated oil is divided into two streams which are passed to separate flash drums 17, 18, wherein the pressure is reduced to 45 lbs. per square inch.  The more volatile constituents are taken off through vapour lines 19, 20.  The two liquid residues are pumped as separate streams through heat-exchangers 23, 24 and furnace 25. The vapours from the flash drums are re-united with liquid streams in furnace 25 which is maintained at 650 DEG  F.  The two streams are then passed together into tower 26 where the pressure is reduced to 8 lbs. per square inch gauge, and head and base temperatures of 185 DEG  and 625 DEG  F. respectively are maintained.  Light naphtha and steam taken overhead, condensed and partly returned as reflux; the remainder of the light naphtha being withdrawn through line 32. The bottoms from tower 26 are passed through a second furnace 34 into tower 35 where an absolute pressure of about 95 mm., and head and base temperatures of 175 DEG  and 765 DEG  F. respectively, are maintained.  Light gas oil is withdrawn through line 38, and cooled in heat-exchanger 13 and cooler 40; part is then returned as head reflux while the remainder is withdrawn through line 42. A lower side stream withdrawn at about 635 DEG  F. through line 43, is cooled in exchanger 23 and cooler 45, and returned to tower 35 as middle reflux stream through line 46.  A third side stream is withdrawn through line 47 and passed to stripper 48; and the lighter constituents are returned through line 49.  Heavy gas oil is withdrawn from the base of the stripper at about 650 DEG F., cooled in exchange 24 and cooler 52, and then removed from the system.  A heavy product, containing salt, is withdrawn from the base of tower 35 through cooler 54 and line 55.  Steam is removed from the top of tower 35 through line 36.

P., 3, Ingleby Way, Chislehurst, Kent. Jan. 20, 1932, No. 1724. Drawings to Specification. [Class 40 (iv).] A single-motion' group selector which has double-ended wipers the ends of which come into engagement with corresponding rows of terminals in turn is controlled numerically over a single bank of a marking switch which, dependent on a discriminating relay controlled from the preceding selecting stage, moves one or two steps for the first impulse to select a main group corresponding to the ends of the wipers to be used and thereafter advances two steps per impulse to positions corresponding to the groups of outlets in the selected main group. The discriminating relay may be controlled by a signal over the line circuit when the selector is seized, or it may be included in one of two routes of access to the selector. A preliminary rotation of the selector wipers through 180‹ takes place when necessary under the control of this relay. The scheme may be extended for the control of a selector in which it is necessary to make a preliminary selection from more than two main groups. A group selector with a common control circuit is described which is identical with that described in Specifications 378,585, (Figs. 9 and 10), and 378,586. Specification 388,173 is referred to.
