Title: Process for the production of stable storable raw food
IPC: A23B7/08
Filed: 1938-03-10
Abstract: Stable, storable, raw food products are prepared by triturating fresh vegetable foodstuffs such as fruit, carrots, onions, radishes, spinach, or beetroots in the presence of sugars such as cane sugar or invert sugar or honey, if desired in the presence of acids such as malic or lactic acid on rolling mills or other shearing comminuting machines, the resulting pulp being dried by means of a current of dry air without a rise in temperature to a water content of about 25-35 per cent by weight, the comminution being then repeated, if desired. In examples: (1) carrots are reduced to a fine pulp on a rolling mill with the same weight of a mixture of equal amounts of artificial honey, prepared from invert sugar to which aromatic essences and, if desired, glucose syrup are added, and of sucrose syrup sp. gr. 1,33, 1 per cent of citric acid being added, the resulting mass being spread out in thin layers on metal sheets and dried in a current of cool air having a relative humidity of 10-15 per cent to a water content of 30 per cent, the mass being finally passed twice through the rolling mill to increase its fineness; (2) equal parts by weight of onions and honey are worked up to a pulp in a rolling mill and dried to a moisture content of 35 per cent; (3) equal parts by weight of dandelion leaves and grape sugar are worked up to a fine pulp and mixed with 2 per cent of a mixture of equal parts of citric and lactic acids, dried to a water content of 25 per cent and further reduced on a rolling mill.

Abstract: Foundry moulds and cores are produced by intimately mixing a major proportion of granular refractory material and a minor proportion of a mixture of a condensate of an aldehyde and a dihydric phenol and formaldehyde or furfuraldehyde, charging the mixture into a heated mould or core box and allowing the binder to harden therein.  The dihydric phenol may be mixed with one or more monohydric phenols. The formaldehyde may be supplied as paraformaldehyde or heramethyline tetramine.  The mould or core box may be initially heated to a temperature between 140 DEG  and 350 DEG C.  Suitable refractory material is silica sand, zircon sand or quartz.  The phenol aldehyde condensate is prepared with deficiency of aldehyde.  Suitable dihydric phenols are resorcinol; 1,3-dihydroxy-5-methyl benzene; p.p1-dihydroxy diphenyl methane and p.p1-dihydroxy diphenyl propane. Suitable monohydric phenols are phenol; mcresol; 1,3,5-xylenol. Suitable aldehydes are formaldehyde, acetaldehyde, furfuraldehyde. In the example phenol and formalin were heated in presence of HCl. The cooled mixture was adjusted to pH 9 with caustic soda, more formalin added and the mixture again heated. Rescorinol was added and the mixture again heated. Industrial spirit was added to the cooled product, and then paraformaldehyde and Redhill T sand. Test cores were prepared by blowing the sand/resin mixture into a heated core box and leaving the resin to cure therein.

Title: Improvements in or relating to the control of cooling of metal castings
Filed: 1933-03-22
Abstract: 415,180. Casting - plant. NEW BRANCEPETH COLLIERY CO., Ltd., (formerly COCHRANE & CO., Ltd.), Middlesbrough, and WILLIAMS, I., The Poplars, Grove Hill, Middlesbrough. March 22, 1933, No. 8667. [Class 83 (i).] The cooling of metal castings is effected in a number of consecutive stages by moving them from one to another of a series of spaced supporting nests, the temperature of which may be varied as desired, so that each casting is submitted to treatment in each nest. A cast pipe P<1> on a gantry 48 is engaged by one pair of a series of hooks 41, by operating a hand lever, not shown, and cooling blocks 24, 25 are separated by an electric motor 31 and rope gearing 36. The gantry 48 is pivoted to the lower block so that the pipe P<1> as well as those in the cooling recesses 37 are held suspended by the hooks. The blocks are then moved, by the distance between adjacent recesses 37, to the right by means of hydraulic cylinders 46, and then closed. The hooks are then withdrawn thus releasing a cooled pipe p<1> on a gantry 49 and the blocks are moved to the left ready for another operation. The blocks may be water jacketted in series or parallel and some of the recesses 37 may be heated by hot air. The recesses may be lined with asbestos and adapted to receive liners of various sizes for treating smaller pipes. Instead of or in addition to passing fluid around the recesses 37 cold air may be passed through the pipes by means of perforated stoppers z, Fig. 27, inserted by mechanism N or the pipes may be merely stoppered to prevent the passage of air through them. The stoppers may also be used in place of the hooks 41. The machine is adapted to be altered so that pipes of different length can be treated. In a modification, the bottom block 25 is fixed while the upper block 24 can be moved up to release the pipes and carries a truck supporting the hooks 41 which are moved inwardly by fixed cams as they rise. The truck is then moved to the left to advance the pipes, supported by the hooks, from one recess to the next &c. The block 24 is then lowered and the truck returned to the right.

Title: Minute colour-forming capsules
IPC: B41M5/165
Filed: 1961-03-10
Abstract: Microcapsules, having a nucleus of liquid, water-immiscible material which is or which carries a first of two chemical reactants which react upon contact, the nucleous being retained by a rupturable wall of hydrophilic, film-forming polymer material which is coated on the outside with the second reactant which is a water-soluble particulate solid, are prepared by forming an emulsion of the nucleous material in an aqueous sol of one or more film-forming, hydrophilic polymers which are caused to coacervate, e.g. by lowering the pH of the system) and to deposit around and enclose the droplets of nucleous material, the polymer material then being gelled and the particulate solid coated thereupon and the capsule hardened, e.g. by treatment with glutaraldehyde solution.  In a modification of the process, the conditions are adjusted so that initially single capsules are formed which subsequently form "clumps" which are coated by more polymer material to give single units which may be coated with the second reactant as described above.  Preferably, the capsules have an inner wall of ethyl cellulose between the nucleous and polymer wall this being obtained by dissolving ethyl cellulose in the liquid of the nucleous whereby a film of this material forms around each droplet when it comes into contact with the aqueous polymer sol.  The capsules find application in the manufacture record material sheets (see Group VIII).  Specification 896,458 is referred to.
