Title: Edible protein fibres based on casein and a process for preparing said fibres
IPC: D01F4/00
Filed: 1972-12-08
Abstract: 1398179 Food preparations COOPERATIEVE CONDENSFABRIEK "FRIESLAND" 8 Dec 1972 [10 Dec 1971] 56764/72 Heading A2B [Also in Divisions B5 and C3] Edible protein fibres useful as a meat substitute are based on casein and contain, besides the ionic groups present in the casein, 0.04-0.20 gram-mole alkaline earth metal ions, 0.005-0.080 gram-mole of alkali metal and/or ammonium ions and 0.012-0.60 gram-mole of polybasic acid anions, per 100 grams of protein. A viscous 5-20% solution of the casein containing the requisite ions is prepared, the solution is extruded at 10-40‹C through a spinneret into a solution containing 2-10% by weight calcium lactate and 15-25% sodium chloride in water at a temperature of 40- 90‹C, and the fibres obtained are washed with a 1-5% solution of the salts used in the extrusion bath (or calcium gluconate) to stabilise the formed fibres. According to a modification, a casein solution somewhat deficient in the required ions is extruded and the fibres are then treated to rectify the ionic deficiency prior to stabilisation. The starting material may be obtained by adding calcium hydroxide, sodium bicarbonate, sodium dihydrogen phosphate, mono-sodium citrate, orthophosphoric acid and/or citric acid to a suspension of acid casein in demineralised water or to a solution of sodium caseinate, or by centrifuging milk at 60,000 g. to obtain a calcium caseinate-phosphate complex. The resulting fibres from this last mentioned source may be blended with egg albumin, wheat gluten, onion powder, skim milk powder, whey powder, mono-sodium glutamate, concentrated beef aroma and permitted colouring to prepare rectangular blocks of a simulated luncheon meat or salami-type sausage, capable of being cooked in water at 100‹C or fried with butter.

The reducing agent may be an alkali metal dithionite, alkali metal or zinc formaldehyde sulphoxylate (e.g. Na HSO 2 . CH 2 O. 2H 2 O), hydrazine, hydroxylamine or a salt thereof. The addition of reducing agent may be regulated automatically by means of a redox measuring chain e.g. a combination of a redox potential measurement and a pH measurement. An optical brightener e.g. a stilbene, stilbene triazole or stilbene triazine may be added to the bleach-fix bath or be present in a final bath (see Ex. 3).

Abstract: 1411449 Feeding webs EICKHOFFUNIVERSAL WELLPAPPENMASCHINEN GmbH 19 Dec 1972 [20 Dec 1971] 58453/72 Heading B8R A roll 4 of paper is delivered to an unrolling apparatus on a carriage 14 mounted for movement on a rail 15 extending parallel with the axis of the roll, the rail being pivotable about a longitudinal axis to tilt the carriage and eject the roll. The carriage includes running gear 20 housed in opposed channel section members 16 of the rail. These members are fixed to a base plate 17 to which is bolted a flattened, circular section member 25 located in the U-shaped cutout portions of upright support plates 21. Thus for roll ejection, e.g. to a position between hydraulically operable, roll core engaging cones on hydraulically pivotable arms (8), Fig. 1 (not shown), of the unrolling apparatus, a lock 29 is released and the rail is manually pivoted to a position in which the base plate 17 engages the edge 28 of each support plate 21. A member (26) may facilitate correct roll location. The circular section member 25 may be located offcentre with respect to the base plate 17.

Title: Conveying apparatus including chains carrying grippers for conveying plastics sheeting in automatic thermo-forming machine or the like
IPC: B65H5/08
Filed: 1971-12-17
Abstract: 1370117 Endless conveyers for plastic sheeting SIEMAG SIEGENER MASCHINENBAU GmbH 17 Dec 1971 [18 Dec 1970] 58624/71 Heading B8A Plastic sheet 30 is conveyed by being engaged by sets of grippers 18, 21 carried by double endless roller chains 5 on either side of the sheet. Each gripper comprises a fixed member 21 (formed by an angle member secured to rivets of the roller chain) and an upwardly movable member 18 downwardly urged by a spring 19. A tappet 17 rigid with the member 18, is adapted at the beginning of the conveying run to engage the periphery of a cam wheel 27 (Fig. 1). This lifts the member 18 out of gripping position. At this stage, the member 18 is rotationally out of register with the member 21 and while lifted, a cam 22 on the member 18 engages a stop 24. This deflects the member 18 into registry, and as the tappet 17 comes down off the cam surface of the wheel 27, the sheet 30 is thus gripped between the members 18 and 21. The member 18 has a further cam surface 23 which engages a stop (26) (Fig. 2, not shown) at the end of the conveying run. This causes the member 18 to be deflected at the same time as it is lifted out of gripping engagement by the action of a cam wheel (28) similar to the cam wheel 27. So that the cam surfaces of the members 18 can pass back beyond the stop 24 on the return stroke, this stop is carried by a member which is pivotally mounted at 34. A cam surface 35 is formed on the latter member so that the stop can be cammed upwards on the return stroke. A third 33 (Fig. 1) is provided to pivot the jaws out of line at the end of a return stroke.

A container 14 surrounds the tray 8 to receive any liquid overflowing therefrom and is connected by a pipe 15 to the reservoir 10 or by means (not shown) to a sump 34 arranged to receive developer scraped from the imaging drum 1 by a cleaning blade 31. As shown, a roller 9 picks up the liquid from tray 8 and supplies it to a patterned roller 7 which is doctored by a blade 20 and applies the liquid to drum 1. The apparatus is preferably enclosed in a housing 17 so that when incorporated in a desk top copier, movement of the copier does not spill the liquid.
