Patent GB-1009587-A (GB)
Title: Casings
IPC: A22C13/00
Filed: 1964-05-06
Abstract: A paper web is formed on a conventional paper making machine by beating long hemp fibres into a slurry and then forming a web and drying.  The web is then passed through or contacted with a dilute viscose solution and again dried whereby the cellulose is partially regenerated.  The cellulose in the viscose is further regenerated by passing the paper web through dilute acid solutions and washing solution.  A cationic thermosetting resin may be used in place of the cellulose.  In an alternative embodiment, a cationic thermosetting resin may be added to the beater of the paper making machine prior to formation of the paper web.  In an example a long hemp fibre pulp was formed into a slurry on a paper making machine; a colloidal solution of a cationic melamine-formaldehyde resin was added to the slurry in an amount of 2 1/2 % by weight of resin to pulp.  The pulp was then formed into a web on a conventional wire belt and dried.  The porous paper web thus formed was suitable for cutting up and manufacturing sausage casings.  The formed sausage casings were subsequently treated by applying viscose and regenerating cellulose therefrom so as to form a seamless tubing. Specification 803,193 is referred to.ALSO:A food casing has on its inner surface a water-insoluble resin obtained by curing a water-dispersible cationic thermosetting resin.  According to one embodiment, a flattened tubular cellulosic sausage casing is passed through a glycerin-water solution and then through a first pair of squeeze rollers.  A quantity of coating composition is introduced into the casing which is then passed between a second pair of squeeze rollers.  As the casing continuously passes through the two pairs of rollers, successive portions of the inside surface thereof contact the coating composition and are coated therewith.  The casing may be of regenerated cellulose containing a paper web embedded therein. In an alternative embodiment, a paper web is formed and is either impregnated with synthetic resin material after forming or has the synthetic resin material added to the beater stage of the paper making machine.  This paper web is subsequently made up into a food casing.  This casing may subsequently be treated by applying viscose thereto, allowing the viscose to penetrate into the fibres and subjecting the resultant tubing to a treatment for coagulation of the viscose, thus producing a seamless tubing. The term "water-dispersible cationic thermosetting resin" is intended to include water-soluble compositions.  Suitable resins include the reaction products of epichlorhydrin and polyamide, water-soluble cationic modified melamine formaldehyde resins, and water-soluble cationic modified urea formaldehyde resins. Specification 803,193 is referred to.

Title: Means for controlling the traverse of cutting-off means in machines where the cutting-off means moves with the moving stock
IPC: B23D45/18
Filed: 1957-06-14
Abstract: 822,101. Shearing. KRUCKELS, T. June 14, 1957, No. 18766/57. Class 83 (4). [Also in Group XXIII] In a flying cut-off device for severing continuously moving stock, a carriage carrying the severing mechanism and a gauge is moved by a power device with the stock, a control associated with the gauge and actuated by the leading end of the rod serving to control the power device to maintain the carriage in the correct position relative to the stock during severing. A shear blade or saw may be used. In an hydraulic system, engagement of the end of the stock 1, Fig. 1, with a stop 21 adjustably mounted on a rod 20 opens a valve 17 secured to the carriage 3 and exhausts the end 15 of a cylinder 6 which moves over a fixed piston 5 to move the carriage and the severing mechanism 2 with the stock 1. Movement of the cylinder 6 tends to close the valve 17 which takes up a position to maintain the severing mechanism 2 at the correct distance behind the end of the stock 1. When the severed piece is ejected a spring 8 closes the valve 17 and the cylinder 6 returns to its initial position. In a modification, the stop 21, Fig. 2, engages one of contacts 30, 32 being urged by a spring towards the contact 30. In the initial position engagement of the carriage 3 with a contact 31 disconnects the contact 30. When the end of the stock engages the stop 21 closure of contact 32 actuates an electromagnetic clutch 24 to couple a screwed shaft 23 to a constantly rotating drive shaft 26 and the screwed shaft drives a fixed nut 22 secured to the carriage 3. When the carriage 3 tends to overrun stop 21 engages contact 30 to actuate an electromagnetic clutch 25 to reverse the shaft 23. Thus by the rapid switching in and out of the clutches 24, 25 the severing mechanism is maintained in the correct position during severing. After severing engagement of stop 21 with contact 30 returns the carriage 3.

Title: Improvements in or relating to film sound records
IPC: G11B7/00
Filed: 1937-07-06
Abstract: 498,394. Optical sound - recording- WESTERN ELECTRIC CO., Ltd. (Electrical Research Products, Inc.) July 6, 1937, Nos. 18768 and 34625. [Class 40 (ii)] Relates to the recording on sound films of double-hump records, both of the symmetrical and the "variable aligmnent" (push-pull) types, in which ground noise is minimized by forming on the positive record a blackened central trace bounded on its edges by lines constituting the envelopes of the sound traces. Figs. 1 and 2 show records of the two kinds concerned. According to the invention, 'the recording light beam is passed through a slit 8 located at right-angles to the direction of travel of the film 10, and the operative length of the slit is defined by a pair of shutters or ribbons 3, 4, which are arranged parallel to the direction of travel of the film and vibrate towards and away from each other to modulate the two lateral edges of the beam and thereby to produce the traces a, while a triangular- or wedge-shaped masking shutter 6 is arranged to project into the centre portion of the beam and is controlled in accordance with the sound intensities in order to produce the central trace b. The sound currents are passed through the ribbons 3, 4 in series to produce a symmetrical record of the type shown in Fig. 1, and in parallel to produce a record such as is shown in Fig. 2. In the arrangement shown, light from a source 1 is focused by a lens system 2 at or near the plane of the ribbons, preferably a short distance in front of or behind the ribbons if a source such as a coiled incandescent filament is used. A lens system 5 sharply focuses an image of the ribbons on a slit 8 in an opaque reflecting plate 7, and an image of the slit is produced on the record film 10 by an objective lens system 9. The wedge-shaped shutter 6 is carried by a rod 26 vibrated by a moving coil instrument 12 or the equivalent supplied with rectified and filtered sound currents. The wedge may have curved or partly straight and partly curved edges to produce an envelope trace. The slit 8 may be divided into two parts, or the tip of the masking shutter may be prolonged as a thin rod to obscure the centre of the slit. Light from the slit passes through an inclined semi -transparent plate 16, so that a portion is deflected to a monitoring cell or cells 15. Some of the light is reflected by the film 10 back along the optical axis and thence by the plate 16 to a device 17 for viewing the image. An enlarged image of the illuminated area of the plate 7 is formed on a ground-glass viewing screen 20 by means of an optical system 18, 19, so that the size and location of the image formed on the plate 7 may be measured and the location of the shutter 6 may be checked. Instead of being located near the slit 8, the shutters 6 may be at any other convenient place in the light beam, e.g. adjacent to the ribbons or to the film. Specification 444,015 is referred to.
