Abstract: 1289271 Polystyrene fibres WESTVACO CORP 28 April 1970 [7 May 1969] 20469/70 Heading B5B [Also in Division D2] Blushed fibres of polystyrene which are white and opaque in the absence of mineral pigments and preferably have lengths from 0À01 mm. to 0À41 mm., widths in the range 2À6 microns to 10À5 microns and a scattering coefficient of up to 0À61 are particularly suitable for use as filler material in the manufacture of paper. The blushed fibres, suitably of polystyrene with molecular weight in the range 5000 to 250,000, may encase a mineral pigment which may be clay, calcium carbonate, hydrated silica, hydrated alumina, titanium dioxide, or magnesium oxide. In examples they are prepared by two different methods viz: by an atomizing spray technique or under so-called shear conditions. In the former method solutions of normally transparent polystyrene in organic solvents, for example esters, ethers, ketone, alcohols or hydrocarbons, were sprayed from an air atomizing nozzle, to which air was supplied at a pressure between 80-120 p.s.i.g., into a bath containing a large volume of non-solvent for the polystyrene. The distance between the spray nozzle and the surface of the non-solvent was about 1 inch so that spray solution passed through the atmosphere for a short period before contacting the non-solvent. In the latter method solutions of polystyrene were metered as a stream into the non-solvent contained in a Waring blender and under agitation. The blushed fibrous polystyrene formed immediately upon contact with the non- solvent. Suitable non-solvents in each case were methanol, ethanol, water or mixtures of tulse with each other or the solvents mentioned above. Blushed fibres prepared in either way were collected by filtration and washed with the non-solvent and water.

Abstract: 1296420 Restructuring meat UNILEVER Ltd 11 June 1971 [15 June 1970] 28882/70 Headings A2B and A2U [Also in Division B5] A restructured meat product is made by extruding a fibrous comminute of meat as multiple streams concurrently with an edible matrix-forming material, and subjecting the extrudate to lateral compaction, the extrusion process being such that at least some of the fibres in the meat comminute are aligned in the direction of extrusion. These fibres are preferably part of the meat but may, e.g. if the fibrous structure of the meat is destroyed by the comminuting, be added fibres obtained from other meat, or other fibres, e.g. made from soy or groundnut protein. The matrix material may be based on wheat flour or finely milled (non-fibrous) raw meat such as beef or chicken, and may include agents such as wheat gluten, methyl cellulose, heat-setting egg albumen to modify its cohesive and binding properties &c. The lateral compaction of the extrudate may be effected in a tapered nozzle which imparts a regular or irregular crosssection to the product, or in a nozzle of flexible material subjected to periodic distortion by a cam &c. A layer of fat may be applied to surround the product partly or wholly. One form of extrusion apparatus comprises a meat comminute chamber 1, a matrix material chamber 2, and meat extrusion tubes 5 which pass through a plate with openings 7 through which the matrix material is extruded around the tubes 5. An extrusion zone 6 leads into a compaction nozzle 8. The tubes 5, of which only a few are shown, are irregularly arranged and may terminate in the openings 7 short of the zone 6. In a modification, the chamber I contains a rotating knife to prevent blockage of the entrances to the tubes 5 by accumulation of fibrous matter, and the plate containing the openings 7 has secured to it flexible tubes of polyethylene &c such that each tube receives the extrudate from a tube 5 and from the opening 7 surrounding it. These flexible tubes terminate in the compaction nozzle where they are deformed by the tapering bore of the nozzle.

Abstract: 1301532 Automatic control ALLM€NNA SVENSKA ELEKTRISKA A B 5 June 1970 [6 June 1969] 27189/70 Heading G3R A member working on moving material is automatically controlled by signals corresponding to deviations from reference values of values of a property of the material measured upstream and downstream of the working member, the upstream signal being delayed by a time corresponding to transport time between the two points. In Fig.1, strip or wire 15 unwound from a reel 16 is rolled at 11 and wound up on a reel 17. Signals derived from an X-ray gauge 18, corresponding to deviation of input thickness or width from a datum, or alteration of such deviation from a previous value in a repeat measuring system, are suitably delayed at 26 and applied through controllers 28, 22 to influence a photoelectric follow-up servo-system 14 adjusting roll screwdown and, to a lesser extent, speed controllers 23-25 for the rolls and reels so as to ensure a constant thickness or width of material issuing from the rolls. Signals derived from an X-ray gauge 19, corresponding to deviation of output thickness or width from a desired value, or alteration of such deviation from a previous value in a repeat measuring system, are applied through a proportional plus integral controller 27 which also influences controllers 28, 22 to correct such deviations. The deviation or alteration of deviation signals from gauge 18 are also delayed at 21 for a period sufficient to allow the measured material to reach gauge 19 the deviation or alteration of deviation signals from which are then compared with the delayed signals at 20. A function of the difference, derived at 20, is then applied to modify, by addition and multiplication, the correction signals produced at 22. Units 20, 22 may be analogue and employ servo-operated potentiometers. Delay units 21, 26 may be digital. The feed-forward and feedback control systems may be separate and operated on a sequential time sharing basis.

Terminals a, b, connected to telegraph lines, are shunted by a differentiating element C1, W1 producing pulses of alternating polarity in synchronism with received telegraph signal changes, each of which switch over the state of a transistor multivibrator 2 having an integrating element 3 at its output. Single current operation.-If a fault occurs there will be a negative pulse in differentiating element 1 and voltage across element 3 rises and if no further switching occurs within 130 ms. the Zener diodes D3, D4 conduct, providing a voltage on line Ust, switching off the receiver (7) also causing conduction of a transistor T3 thus energizing fault lamp La. On resumption of normal transmission the integrating element 3 becomes discharged, thus Zener diodes D3, D4 cease conduction hence the receiver is reconnected and lamp La is extinguished. Double current operation.-A polarized receiver is provided in which a fault during a negative, marking, current switches off receiver 7; owing to its polarized operation a fault during positive, spacing, current would have the same effect.
