Title: Process and apparatus for the manufacture of synthetic skin structures, more especially sausage casings
IPC: B29C48/10
Filed: 1954-07-27
Abstract: Sausage skins are extruded from an annular nozzle comprising a fixed outer casing the first part of which is cylindrical and the second part is conical, and a rotating core the first part of which is cylindrical and the second part is a conical conveyor worm, whereby the fibrous mass of animal material being extruded is forced through a cylindrical chamber consisting of a fixed outer casing and rotating core and is finally extruded through a fixed annular slit nozzle. The rotation of the core is stated to rearrange the direction of the fibres to produce a skin of improved strength.  A suitable nozzle, <PICT:0756109/IV(a)/1> Fig. 2, comprises an outer casing 1 terminating in a cylindrical portion c, and a core support 3 which carries a rotatable member 4 comprising a toothed wheel 5, conical worm thread g for feeding the material from hopper 6 and cylindrical portion h.  The rotating portion h of the core is followed by a fixed cylindrical portion mounted on the end of core support 3.  The length of the cylindrical rotating portion h of the core is preferably approximately equal to the diameter of the extrusion orifice.  In order to produce skins of different thicknesses, detachable liners may be inserted in the end of the cylindrical portion c of the outer casing.  Specification 433,245, is referred to.

Void [Abridged as open to inspection under Sect. 91 of the Acts, Jan. 28, 1935]. Drawings to Specification. [Class 36] To suppress medium and high frequency disturbing currents in an insulated conductor, the conductor is provided with a conducting screen which is separated from the conductor by a layer of insulating material having a high dielectric constant and preferably a high phase angle. The insulating layer, which is preferably less than 0À5 mm. in thickness, may be stratified and comprise a coating of lacquer and a spun coating of cotton impregnated with artificial resin ; or coatings of cotton impregnated with rubber, and a mixture of rubber and mica may be employed. The screen may comprise one or more layers of spun or braided metal wires, or tapes and is preferably formed of ferromagnetic material. The screen may be held at zero potential, or connected directly, inductively, or capacitatively to earth.

Abstract: 1,162,047. Automatic exchange systems. AGFA-GEVAERT A.G. 12 May, 1967 [13 May, 1966], No. 22090/67. Heading H4K. To obtain access to a device such as an eavesdropping microphone in a children's room or to the controls of an oven, the calling subscriber dials a service code before dialling the number of the wanted but unattended station, the exchange discriminating accordingly. The exchange may discriminate by sending a continuous A.C. to the unattended station where a rectifier distinguishes it from ordinary ringing and effects reply and connection to the device. Where, however, the system is such that before leaving the station unattended the normal station circuit is switched out and the device is switched into the exchange line, and the exchange is requested to route calls to an automatic answering machine connected to the station live circuit, the exchange responds to the service code by disconnecting the automatic answering machine and connecting to the line. In these circumstances reply to a call to the unattended station is made by the control circuit of the answering machine. The con-. nection may be forcibly released after a fixed time.

Fibres are fed to a carding machine from the lower part of a vertical shaft and the mass of fibres in the shaft is maintained at a substantially constant density by discontinuously forcing a column of air downwards through the fibres. The fibres are fed into the shaft 4 from a hopper 1 by feed rollers 2 and a cylinder 3 and are delivered from the shaft by rollers 5. An adjustable photodetector 9 is arranged to cause stoppage of the rollers 2 when the fibres reach a predetermined level in the shaft. During the time that the carding machine is running a plunger 7 is continuously reciprocated in a cylinder 4a. During its upward motion it draws in air through a flap 8 that is closed during descent of the plunger which then forces air through the mass of fibres in the shaft 4 and out through openings 6. Plunger speeds may be varied according to the nature of the fibres being fed.

Slabs of compressed fibres are arranged in horizontal layers in a stack and tufts of fibrous material are removed from end faces of the slabs in directions parallel with the planes of the slabs. The stack is fed towards the tuft removal device by four spiked lattices, such as 4, 6, and pushed through a rectangular compacting frame 6 in front of which the tuft removal device traverses. This device may consist of two picking rollers 7, 8 located between sheet metal panels (Fig. 2, not shown) or grooved rollers 22-26, Fig. 3. The panels or rollers 22-26 may exert resilient adjustable pressure on the fibre stack and prevent excessively large batches of fibrous material being removed from the slabs. Tufts picked off the stack fall onto a grating 12 through which impurities fall and the fibres pass forward over a succession of cleaning rollers 13-16.

Abstract: In a process for obtaining sinterable uranium oxide, uranium dioxide is made by reduction at 700 DEG  to 1000 DEG  C. and immediately oxidized at 700 DEG  to 1000 DEG  C. in an atmosphere containing water vapour but otherwise free of elemental or combined oxygen.  The uranium dioxide preferably is made by dissociating and reducing ammonium diuranate at 700 DEG  to 1000 DEG  C., but may be made by reduction of uranium trioxide UO3), uranium trioxide hydrate, uranium oxide (U3O8), uranium peroxide (UO4) or non-stoichiometric uranium dioxide.  The reduction may be in hydrogen, a mixture of an inert gas, e.g. nitrogen, and hydrogen, or in carbon monoxide. The oxidation may be in nitrogen or argon containing water vapour provided by passing the gas through water at 80 DEG  C.  The sinterable uranium oxide product has a composition between UO2.02 and UO 2.08.  Examples are given.

Title: Improvements in apparatus for removing empty packings from a supply receptacle
IPC: B65B43/16
Filed: 1960-06-28
Abstract: 915,846. Feeding sheets. HOLLER, W., and HOLLER, F., [trading as HOLLER MASCHINENFABRIK GEB.]. June 28, 1960 [July 4, 1959], No. 22647/60. Class 100 (1). Flat bags 33 in a stack in a magazine 7 are separated sequentially and transferred to a continuously moving conveyer 8 by a number of rotatable pick-up heads each including a blade 1 which is inserted within a bag by a sliding vertical movement, and the bag is conveyed away by the head which remains always in a vertical position. When a blade 1 is inserted into a bag, a pair of gripper arms 25 is actuated to grip the bag against the blade to assist the removal and conveyance of the bag. As shown, there are four heads each comprising an arm 2 pivoted on a fixed central shaft 13, the arms being so shaped that their outer portions rotate in the same vertical plane. Each arm 2 has a bearing 23 for a pin 21 which carries a holder 28 for the blade 1 at one end, and forms a bearing spindle at the other end for a satellite gear 3. The gear 3 meshes with an intermediate gear 4, and the latter meshes with a sun-wheel 5 secured to the fixed shaft 13, all the gears being of the same diameter. The arms 2 are rotated about the shaft 13 by a gear-driven rectangular plate 10 which has four cranks 18 each slotted at the outer end to engage a pin on an arm 2. Since the planetary gears 3, 4, 5 are of the same size, the gears 3 do not rotate, and the blades 1 mounted on the gears 3 thus remain vertical. Each arm 2 is arranged to be accelerated and retarded in its rotation about the shaft 13 by a constantly-rotating control cam 6 which acts on crank arms 17 and the cranks 18 secured to the drive-plate 10; thus the speed of the arms 2 can be adjusted at the bag pick-up and delivery positions. The pin 21 connected to the blade holder 28 is also connected to V-shaped element 20 which, as the arm 2 rotates, abuts rigid cam elements or, as shown, engages between rollers 32 of a control lever 22 which move the pin 21 and blade 1 horizontally and hold it there during the rotation of the arm 2. The hub 23 on the arm 2 has a cam track 24 thereon engaged by a roller 27 on an arm pivoted on the blade holder 28 at 26. A pair of gripper arms 25 as also mounted on the pivot 26, so that as the pin 21 and holder 28 are moved horizontally, the grippers 25 clamp a bag against the blade 1 and hold it clamped until the bag is released at the delivery position. The bag 33 is released on a reciprocating support-plate 30 which is moved at the same speed as the delivery chains 8, and the bag is placed by the plate between holders 31 on the chains which conveys it to a bag-filling &c. machine.
