Title: Dehydrated purees and method and apparatus for preparation thereof
IPC: A23L19/00
Filed: 1960-05-20
Abstract: 938,381. Dehydrated and flaked food. GENERAL FOODS CORPORATION. May 20, 1960 [May 20, 1959; June 4, 1959; July 2, 1959], No. 17835/60. Class 49. Rapidly reconstitutable dehydrated food flakes are produced by concentrating a puree, i.e. a liquid or semiliquid food material of 9 to 30% solids content and having a relatively high percentage content of natural or added sugars and/or pectinous substances, to a moisture content of from 2 to 15%, forming it into a film, e.g. 0.005 to 0.050 inch thick, on a heated surface, and while still plastic, e.g. at 212‹ F., stretching the film sufficiently to produce minor ruptures in it without breaking its continuity. The film is then cooled, if necessary, e.g. to below 70‹ F., using refrigerated, dehumidified air, dried and broken into flakes at below 30‹ F. of a size passing a 10-mesh sieve (U.S. Standard) but not a 40 mesh sieve. The puree may comprise comminuted fruit and/or vegetable solids and/or juices, meat solids, dairy products, flavourings and include, if necessary, one or more added stretchable film-forming substances, e.g. starches, polysaccharide and/or cellulose ethers such as pectin, algin, Irish moss extract, gum arabic or acacia, alkali metal carboxymethyl celluloses, ethyl, methyl or other celluloses or hydroxycelluloses, and proteinaceous mineral or vegetable matter such as soybean or peanut protein or fish protein. As shown, Fig. 3, a puree is delivered to the nip between steam-heated drums 20, 22 spaced 0.006 to 0.015 inch apart, where it is concentrated before forming a thin film on the drum surfaces which is doctored off at 24 and taken over a tension applying stretched roll 30 of woven wire or expanded metal, through which suction may be applied, if desired, the film being pressed on to the roll surface by hard rubber rider wheels 32 (or a single roll with spaced circumferential grooves gouged out). The curtain of film then falls into a hopper and breaker assembly 42, Figs. 1 and 5, passing between guide wires 48 into contact with breaker arms 52 on a rotating shaft 54, the broken pieces entering a conveyer/flaker 28 comprising a screw 34 rotating in an insulated tube 36 through which a current of cold air is circulated via inlet 60 and outlet 62. Finally the broken product cascades over rotating flaker paddles 64 which brush it through a circumferential screen 68 inside a hopper 69. The refrigerated air system comprises, Fig. 4, not shown, in series from outlet 62 to inlet 60 a cyclone separator, a silica gel dryer, a heat-exchanger, a heating unit and a fan. The heating unit just slightly warms the chilled air, rendering it capable of taking up more moisture.

Abstract: 945,357. Automatic exchange systems. SIEMENS & HALSKE A.G. May 20, 1960 [May 29, 1959], No. 17922/60. Addition to 904,463. Heading H4K. The path-seeking circuit arrangement of the parent Specification is modified by the use of a network of busying wires c which is also used for path-seeking, a busy potential set up at busy path sections as a busy criterion also serving to mark with busy potential the associated path-seeking network, a common intermediate link selector ZLW being arranged to select a path extending from one inlet of an inlet coupling multiple A to any free outlet in a particular row of the associated outlet coupling multiple B, this selector ZLW being connected in each case to that coupling field (such as A . . . B) through which the path is to lead, and the common path-seeking network being associated with all the outlet coupling multiples, and being connected during pathseeking and selection only to those row wires of the network of busying wires which lead into and out of the outlet coupling multiple of that coupling field in which a path is to be sought. Assuming that a path is to be set up from the inlet Tj to an outlet of group Dl, the allotter and marker close contacts such as lyk (Fig. 4) so that the path-seeking network is connected via gating rectifiers such as G<SP>1</SP>k to the c wires of the coupling field concerned, and contacts such as 2yk/1 so that the path seeking network is connected to the c wires of the coupling field outlets concerned. The marker also opens contact dl of the desired outlet group Dl so that the potential - U connected to relay sl.k associated with outlet Zl.k can be effective as " free " potential via resistor W<SP>1</SP>l.k. The selector ZLW then chooses a free intermediate link giving access to a free outlet in the wanted group.

Title: Improvements in or relating to hydraulic jacks and power actuated systems including such jacks
Inventor: WATSON CYRIL DANIEL
IPC: B64C13/24
Filed: 1949-07-09
Abstract: 690,219. Hydraulic machines ; Huid-pressure servomotor-control systems. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Aug. 23,1950 [July 9, 1949], No. 18216/49. Classes 69 (ii) and 135 [Also in Group XXX] In a hydraulic servomotor-control system of the kind described in Specification 632,513 suitable for the operation of aircraft control surfaces, a hydraulic vane motor 53 is secured to the threaded shaft 48 which co-operates with the threaded piston 10 to either assist or restrain rotation of the threaded shaft. As shown in Fig. 1, the screw-threaded shaft 48 is made irreversible and the vane motor 53 housed in an extension of the cylinder 11 and connected by ducts 60, 57 to the valve casing. On movement of the pilot valve 17, e.g. to the left on rotation of the shaft 47 either electrically or manually, the main valve 28 moves to the left to connect the pressure duct 13 through the duct 60 simultaneously to the left-hand end of the cylinder I and the vane motor 53 and the exhaust duct 14 through the duct 57 to the vane motor. Thus rotation of the vane motor permits the axial movement of the piston 10 under the pressure applied to its left face. Rotation of the shaft 48 through bevel gears 50, 51, 52 recentres the valve 17 with respect to the valve 28. Under normal operation, a spring-loaded stop 63 is held out of engagement with the splined shaft 42 by liquid pressure. In the event of failure of the liquid pressure the stop 63 engages in a recess 64 on the shaft 42 whence rotation of the shaft 47 moves the valve 17 into engagement with one of the end stops 65, 66 to move the valve 28 to connect the vane motor and the left-hand end of the cylinder 11 with the exhaust duct 14 and lock the shaft 42 to the bevel gear 52, so that the shaft 48 may be rotated and hence the piston 10 axially moved through the gears 52, 51, 50. As shown in Fig. 2, the screw-threaded shaft 48 is made reversible, i.e., rotation of the shaft moves the piston 10 and movement of the piston rotates the shaft. In this case, the duct 60 supplies pressure liquid to the cylinder 11 only, the vane motor being connected to a port 70 in the valve casing by a duct 78 whilst the duct 57 branches into two ducts 73, 74 housing oppositely disposed non-return valves controlling ports 71, 72 in the valve casing. In the neutral position of the valves 17, 28, the port 70 is masked by a land 69 on the valve 28, the vane motor 53 then being hydraulically locked. On movement of the valve 17 to move the valve 28, pressure liquid circulates through the vane motor 53 in the corresponding direction but at a rate which retards the movement of the piston due to the restriction of the ports 70, 71, 72.

Title: Improvements in or relating to the catalytic production of amines
Filed: 1930-06-20
Abstract: Alumina suitable for use as a dehydrating catalyst is prepared by pouring a saturated alcoholic solution of aluminium ethylate into ethyl alcohol containing 2 per cent of water.  The mixture sets to a gel, which is allowed to stand, then dried at a temperature gradually rising to 110 DEG  C., and finally roasted at 500-600 DEG  C.ALSO:In the manufacture of amines by passing a lower aliphatic alcohol and ammonia over a dehydrating catalyst at a raised temperature, the reaction is directed towards the production of primary, secondary, or tertiary amine, as may be desired, by including in the reaction mixture a quantity of the undesired amine or amines.  The proportion of alcohol to ammonia may also be varied in accordance with the type of amine desired.  Thus, primary amines may be prepared from a reaction mixture including the corresponding secondary and (or) tertiary amine, and containing a molecular excess of ammonia over alcohol.  Secondary or tertiary amines may be prepared from a reaction mixture including one or both of the corresponding undesired amines, and containing a molecular excess of alcohol over ammonia. The undesired amines may be separated from the reaction products and recirculated.  Examples are given of the manufacture of the methylamines from methyl alcohol and ammonia, with the use as catalyst of alumina prepared as described below.  Alumina for use in the process described above is prepared by pouring a saturated alcoholic solution of aluminium ethylate into ethyl alcohol containing 2 per cent of water.  The mixture sets to a gel, which is allowed to stand, then dried at a temperature gradually rising to 110 DEG  C., and finally wasted at 500-600 DEG  C.
