Abstract: 1,274,254. Conveyers. STORK AMSTERDAM N.V. 23 Sept., 1969 [10 Oct., 1968], No 46849/69. Heading B8A. Apparatus for treating articles, e.g. for sterilizing or pasteurizing foodstuffs in jars, comprises a conveyer 2 having rotatable articlecarriers 9 which may be loaded and discharged, at stations 16, 17, respectively, by belt conveyers 21 having a vertically movable frame 23. The carriers 9 are mounted on at least two parallel chains driven by one or more sprocket wheels 11 but by providing vertically movable guide wheels 13, 15 and chain loop portions 14, the conveyer may be temporarily stopped in a region 7 where the stations 16, 17 are located. After loading and unloading two compartments of a carrier by the conveyers 21, the frame 23 is lowered and the carrier is rotated to permit the loading/unloading of the remaining compartments whereafter the carrier is moved by the restarting of the conveyer 2 in the region 7. The carrier may be rotated by a rack or by a chain which engages a gear secured to the carrier. The carrier compartments may be arranged in groups in the form of a pentagon or a hexagon, Figs. 3, 4 (not shown). A treatment space 1 is sealed by water locks 4. In a modification, the conveyer 2 does not stop in the region 7 and the conveyers 21 are correspondingly moved transversely to their longitudinal axes, after which they return to their starting positions while the carriers are rotated to their next loading and discharging positions.

The output produced is measured by neutron flux and the output removed is determined by measuring output given up from the core at the steam generators or by measurements of the output of the steam generators. These measurements are fed as signals to a combustion device which forms the continuous integral, and the control signal obtained may bring about shut-down of the reactor.

[Also in Divisions A4 and B8] A device for positioning at a grocery checkout counter to permit efficient manual packaging of groceries comprises a plurality of nested flexible plastics bags 5 held open on a tubular frame 6 of a stand 9 by having their open ends collectively folded outwardly and backwardly over the upper edge of the frame to form nested turned-back cuffs which so permit ready removal of successive bags. The nested bags are made, Figs. 2-8 (not shown), by winding a single web of plastics film 12a about a rotatable mandrel 10 to overlie one end portion of the tubular frame which itself overlies an end portion of the mandrel, heatsealing the end of the wound film to the light of the film and cutting the film to form a longitudinally seamed tube heat-sealing a circular plastics film piece 21 around its periphery to one end of the tube, repeating the procedure to build-up a plurality of bags one upon the other on the mandrel, removing the mandrel and moving a plunger 25 against the closed ends of the nested bags axially inwardly of the tubular frame 6 thereby providing the nested bags having turned-backed cuffs. The mandrel plus the completed bags are rotated through a slight angle after each bag is successively formed to avoid alignment of the longitudinal seams of plastics bags.

Filed: 1963-12-06
Abstract: A lubricating grease by dispersing a synthetic clay-like mineral of general formula <FORM:1121501/C4-C5/1> where M is an organic cation, x is greater than zero and less than 6, y is at least 1.0 and less than 4, and n is an integer from 1-3, in, for example a light spindle oil.  Preparation of the clay, see Division C1.ALSO:Synthetic clay-like minerals of general formula <FORM:1121501/C1/1> where x = 0-6, y = 1-4, n = 1-3 (integral) and M is a replaceable organic or inorganic cation, as given in claim 1 of Specification 1,054,111, are prepared by the method of that application in which the final heat treatment is omitted. The reaction product of the process of the parent application may be further reacted in an aqueous medium with an organic compound or a salt thereof which compound gives rise in the aqueous medium to exhangeable organic ammonium cations.  The washing and dewatering steps of the process of the parent application may also be omitted.  Examples of organic compounds or salts thereof from which the cations may be derived are the salts (including quaternary salts) of primary, secondary and tertiary amines, such mono-, di-, tri- and polyamines as well as aliphatic, aromatic, cyclic and heterocyclic amines and substituted derivatives thereof. The amine in the salt may have an organic radical of at least 18 carbon atoms chain length.  The organic compound may be employed in amount to give from 0.9 to 1.4 equivalents of organic cations, so that in the synthetic clay product substantially all the exchangeable cations is organic cations.  The organic radical present may have at least 10 carbon atoms.  Compounds specified are "Ethomeens" (Registered Trade Mark) and "Ethoduomeens" (Registered Trade Mark). Other organic ammonium cations specified are dimethyl dioctadecyl ammonium, trimethyloctadecyl ammonium, dodecyl ammonium, hexadecyl ammonium, octadecyl ammonium, dioctadecylmorpholinium, 1 - propyl - 2 - octadecylimidazolinium and bis(-2-hydroxy ethyl) octadecyl ammonium.  The organic cationic materials may be prepared by reaction of the metallic cationic clays with the organic compounds or salt thereof in aqueous medium.  The product may be separated by washing, dewatering and drying.  The exchange may be carried out on the dry metallic cationic material or on the slurry from its preparation, or on the filter cake.  Alternatively, the adduct may be formed directly by conducting the clay synthesis in the presence of the organic compound. These adducts may be used in the preparation of lubricating greases.  If the exchange reaction is carried out with at least one part five equivalents of the organic compound, substantially the whole of the metal is replaced and the excess organic cation is detained in the synthetic clay which will then have d001 spacing of 38\sB3 <\>rA. These latter products may be used in the preparation of organo sols with liquid aliphatic and aromatic hydrocarbons, e.g. petroleum ether, benzene, toluene and xylene, which disperse in water to form water-in-oil emulsions.
