Title: Improvements in or relating to apparatus for forming tubular films and the like
IPC: B29C48/10
Filed: 1961-02-15
Abstract: 943,283. Producing tubular films; extruding tubes. VERWALTUNGSGESELLSCHAFT DER WERKZEUGMASCHINENFABRIK OERLIKON. Feb. 15, 1961 [Feb. 15, 1960], No. 5710/61. Headings B5A and B5D. In the production of tubular films by melt extruding an organic thermoplastic material to form a seamless tube or thick walled tubular film, biaxially stretching the film while still hot by simultaneously inflating it by internal gaseous pressure and stretching it longitudinally by means of nip rollers through which the cooled and flattened film is passed, and passing the flattened tubular film to means for winding the film as a roll, the molten material is fed under pressure within the extruder along a path which is essentially linear and coaxial with the extrusion die, and a continuous or reciprocatory rotation about the axis of the feed path is imparted to the extruder, or the extrusion die, relatively to the flattening and winding means, or is imparted to the flattening and winding means relatively to the extruder or the extrusion die, to enable irregularities in the thickness of the film to be distributed across the entire width of the final rolled extruded material. As shown in Fig. 2, apparatus for the production of tubular films according to the invention comprises a hollow table member 13 rotatably supported by a bearing 15b mounted in a stationary cylindrical support member 15 provided with an internally toothed portion 18 which meshes with a pinion 17 driven by a reversible motor 16 to provide uni-directional or reversing rotational movement for the table member 13. A particulate solid thermoplastic material 9b is advanced from a supply hopper 9 through the passageway 9a by a screw conveyer 9c to the lower end of a vertical tubular guide member or barrel 8a coaxial with the table 13 and adapted to guide the molten material towards the annular die 5 of an extrusion head 20. The particulate and subsequently molten material is advanced up the extruder-barrel 8a by a screw conveyer 8 and extruded through the die 5 to form a tubular film 2 which is inflated by introducing into it under pressure a gas through an inlet (not shown) in the extrusion head in any conventional manner. The extrusion head 20, the extruder barrel 8a and the rotatable table member 13 constitute a rigid assembly. The heating means for melting the material in the extruder are conventional and not shown. The screw conveyers 9c and 8 are driven by the motor 10 mounted on the table 13 through gear trains 11 and 19 respectively. The tubular film 2 is cooled by cooled air supplied from a blower 12 mounted on table 13 via conduit 12b and an annular air baffle unit 12a. The tubular film 2 is flattened by pinch rollers, of which one is shown at 6, and wound up on the take-up roller 7, these being fixedly positioned relative to the die 5.

Filed: 1975-02-11
Abstract: 1454712 Hydrostatic transmission control OWATONNA MFG CO Ltd 11 Feb 1975 [9 Dec 1974] 5733/75 Heading F2W [Also in Division B7] In a vehicle control means for controlling direction and speed of the vehicle a control bar member 39 is connected to an operating member 37 in a selected one of a pair of positions which correspond to two positions of an operators seat 47 facing in opposite directions longitudinally of the vehicle. As shown in Fig. 2 the vehicle comprises a frame 1 supported at its ends by drive wheels 2 and castor wheels 3. A pair of pedestals 15 supported at one end of the frame 1 pivotally support lifting booms 16, Fig. 1, supporting a bucket 19. The booms 16 and bucket 19 are raised and lowered by hydraulic rams 20, 21 respectively. The castors 3 comprise wheels 24 journaled in forks 25 having vertical pivot shafts 26, Fig. 3, journaled in bearings 27 secured to opposite ends of a beam 28 pivoted to a transverse frame portion 30 by a bolt 29 to provide rocking movements of the beam 28. The drive wheels 2 are each driven from a respective one of a pair of fluid pressure motors 33, Fig. 6, mounted on drive housing 32 and coupled to fluid pumps 34 driven by engine 10. The motors 34 are each controlled by respective control links 35 operated from control bar 39 via operating member 37 and transverse arms 38. The operating member 37 comprises a shaft journaled for rotation on its own axis in a bearing 40 which is pivotally mounted in a bracket 41, Fig. 5, for rocking movements transversely of the vehicle frame 1. The control bar 39 has flanges 45 having aligned openings 46 which may be selectively aligned with an opening in the shaft 37 and bolted thereto so that the bar 39 can be secured to the shaft 37 in either one of a pair of angularly displaced positions shown in full and dotted lines in Fig. 5. An operators seat 47 is. rigidly mounted on a base 48 having depending flanges 49 disposed between a pair of longitudinal frame portions 50 having spaced pairs of aligned openings 51 for reception of anchoring pins 52, 53, the pins 52 being rigidly secured to one of the flanges 49, Fig. 4, and the other pin 53 being mounted for axial sliding in a fixed bracket 54, when it is desired to shift the operators seat to the dotted line position shown in Fig. 5 the pin 53 is retracted from its engaged opening 51 and the seat 47 swung upwardly and raised so that it may be reversed and remounted on the frame. As seen in Fig. 7 a stop plate 60 is provided having an aperture with stop edges 62, 63 which engage with an abutment member 64 on the shaft 37 so that at high speeds the rotary steering movements of the shaft 37 are limited. In a modified control mechanism, Fig. 8, pairs of bifurcated levers 65, 66 are journaled on the frame by shafts 67 disposed on fixed axes, the inner bifurcated ends of the levers 65, 66 straddle the shaft 37. When arm 68 fixed to shaft 37 is moved to one limit of its movement, fingers 69 of a pair of levers 65, 66 engage an adjacent side of the arm 68 to limit rotation of the shaft in a "speed increasing" direction.

Abstract: 198,416. Drysdale, C. V. Feb. 28, 1922. Regulating transformers.-A multiple strip winding for the primary and secondary windings of transformers, in which the separate windings may be connected by means of a commutator in series, parallel, or series-parallel, comprises two or more groups of superimposed turns or portions of turns so arranged that the innermost conductor of one group forms part of the same strip as the outermost conductor of the next, thereby securing approximate equality in impedance and magnetic effect in all the windings. A U-shaped strip for forming a coil of two turns is shown in Fig. 1. The portions A, B are coiled in opposite directions from the connecting end C, and each forms one complete turn, the broader extensions D, E forming contact-pieces. To form a multiple winding a number of such strips are superimposed as shown in Fig. 2, so that the connecting portions C are adjacent, insulations being provided between the turns. The broad extensions D<1> - - D<9>, E1 - - E<9> are bent out to form the contactpieces of a series-parallel commutator. The arms A, B of the U-shaped strip may be made long enough to form a number of turns, or a strip may be formed as two or more U-pieces connected in series, as shown in Fig. 4 for a four-turn winding. Fig. 5 shows a coil in which each strip forms a single turn, the connecting points X<2> of one group of strips X<2>, X<3>. X<4> projecting outwardly from the winding, and the connecting points Y<2> of the other group of strips Y<3>, Y<2>, Y' projecting inwardly.

Abstract: 116,266. Titan Co. Aktieselskabet. May 24, 1917, [Convention date]. Pigments are made from titanium hydrates which have been precipitated from sulphate or other acid solutions and so contain sulphuric or other acid, by treatment with a practically insoluble alkaline-earth compound such as calcium carbonate, to produce an insoluble sulphate &c. and liberate an inert gas so as to render the product porous and homogenous. The proportion of basic substance may be made sufficient to obtain, after calcination, a product containing some calcium titanate. if desired. The product is calcined to drive off the water of hydration, and calcination may be continued to convert the titanium oxide into a crystalline modification. Specification 110,535 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the use of basic material other than that which would cause the evolution of gas during the reaction. This subject-matter does not appear in the Specification as accepted.
