Title: Method of stabilizing fats and fatty oils against oxidation
IPC: C11B5/00
Filed: 1949-07-08
Abstract: Substances of the general formula <FORM:0679192/IV (b)/1> where R represents a methyl or ethyl group and R1 represents a tertiary butyl or tertiary amyl group, are suitable for use as antioxidants in fats and fatty oils (see Groups I and III).  They may be prepared by reacting p-hydroxyanisole or p-hydroxyphenetole with tert.-butyl or tert.-amyl alcohol at a temperature of 80-90 DEG  C. in the presence of orthophosphoric acid as alkylating catalyst. Alternatively, they may be prepared by reacting p-hydroxyanisole or p-hydroxyphenetole with isobutylene or isoamylene in the presence of sulphuric acid. Specification 621,519 is referred to.ALSO:Fats and fatty oils are stabilized against oxidation by incorporating therein a propylene glycol solution of one or more compounds chosen from the group consisting of hydroquinone and those compounds represented by the general formula <FORM:0679192/III/1> where R represents a methyl or ethyl group and R1 represents a tertiary butyl or tertiary amyl group.  Synergizing acids such as one or more of citric, orthophosphoric, metaphosphoric, tartaric or ascorbic acid may also be added.  Fats and fatty oils mentioned are lard, peanut oil, palm oil, coconut oil, cottonseed oil, soya bean oil, sunflowerseed oil, sesame oil and fat-fatty oil mixtures.  In an example, a composition consisting of propylene glycol, tertiary-butylated hydroxyanisole (a mixture of 3-tert.-butyl-4-hydroxy-anisole and 2-tert.-butyl-4-hydroxy-anisole), hydroquinone and citric acid is added to lard, or other fat or fatty oil.

Abstract: 516,066. Impact pulverizers. SKODA WORKS, PLZEN, and TSCHAUNER, L. June 18, 1938, No. 18181. [Class 59] In a hammer-crusher having a feed grate 1, a discharge grate 5 and an intermediate grate 6, the intermediate grate is arranged below the shaft 2 of the hammers and is adapted to catch and support any coarse pieces falling from the feed grate and prevent such pieces from dropping on to the discharge grate until they have been subjected to the further crushing operation.

[Class 144 (ii).] A device for connecting the broken ends of tyre chains 12, 13, Fig. 1, or for connecting the cross and side chains of a tyre, consists of a double-ended hook 14 and a sleeve sliding on the shank thereof so as to permit the insertion of the end links of the chains into the hooks, but in its normal position preventing the disengagement of the links. The sleeve may be formed of a piece of tubing or of sheet metal bent into tube form. In modifications, the sleeve may consist of a series of rings side by side, or a wire helix. Fig. 9 shows a further modification in which the length of the sleeve can be increased by the provision of a slot 36 at one or both ends. In use the sleeve is turned about the shank after the links have been inserted into the hooks to present the slot below the shank. The Specification as open to inspection under Sect. 91 comprises also a keeper device consisting of a resilient member mounted on the shank and adapted to be compressed to allow entrance of the chain links into the hook end. This subject-matter does not appear in the Specification as accepted.

Abstract: In a process for removing impurities from an extract containing material having anti-pernicious an mia activity, e.g. an extract of liver or prepared from micro-organisms, the extract is treated with nitrous acid.  The acidic impurities may be removed by means of an organic solvent, e.g. ether, chloroform, lower aliphatic esters, and butyl and amyl alcohols from the resulting solution, or alternatively by anion-exchange resins.

The bights in the filament are carried by (i) a hook 64 and (ii) loops 57 all supported by a central stem 47 sealed in a node 29 on the closure 28. The hook is held by a strap 65 welded to the stem and the loops by small quartz cylinders 54 in nests 50 on a cross piece 52; the loops are prevented from turning in the quartz cylinders 54 by wire fasteners 59 whose ends 60 are bent over after insertion of loops, washers 61 and fasteners into the cylinders 54. A heat shield 66 is also carried by the stem 47, near the filament and an electrostatic shield 73 is placed nearer the closure 28. In an amplifier the grid 21 is carried by bent rods 72 from a ring 69 sealed to the stem 27; to prevent distortion of the grid at the end remote from the stem a stiff wire 80 is placed on the grid rods inside the turns. The grid lead to the contact 75 may be a single flexible band 74 or a bifurcated lead 76, Fig. 9, may be used. The cap 39 is cemented to the extension 23 and carries bushings 42 to which the leads 37 are secured by screws 43 the leads having metal sleeves 41; one of the bushings is insulated by mica washers 44. A recess 45 is provided for the tip of the exhausting tube 34. The supporting elements of the electrodes are chemically buffed prior to assembly to remove burrs and surface impurities. The tungsten filament and other parts in the valve are cleaned and then buffed by anodic treatment in a bath of dilute caustic soda ; the molybdenum parts are treated in dilute chromic acid and the nickel parts in dilute acetic acid. The copper elements are cleaned in an ammonia bath.

Chain 1 from the chain hoist is fed for storing as loops 11 on guides 7 by toothed wheel 3 mounted on framework 6, the wheel being provided rigidly with a bulge 4 so inclined that periodically it engages and lifts a chain link so that the latter falls on to and slides down the storage guides 7. In order to form loops 11 of preselected size, the toothed wheel 3 is caused to move towards and away from guides 7, the movement being effected by the rotation of the wheel which is transmitted to eccentric 17 via gears 14 and 16. The size of the chain loops is determined by the gear ratio.

Title: Crushing apparatus
IPC: B02C1/02
Filed: 1977-05-05
Abstract: On a base frame (10) which receives a chain scraper conveyor (11), frames (14) on which one fixed, and one movable, crushing jaw (16 and 17, respectively) is supported are located at the crusher inlet or outlet; a drive (21) with a crank drive causes the said jaw to move in an oscillating fashion. The fixed crushing jaw (16) has, viewed in the direction of throughflow, crushing counterbearings (26A - 26D) which lie one behind the other and are arched towards the oscillating crushing jaw (17) and have apex lines (27A - 27D) which are offset in steps with respect to one another, and the movable crushing jaw (17) has crushing bars (25A - 25D) which lie opposite the crushing counterbearing (26A - 26D). As a result, the material to be crushed is broken up in steps so that even material to be crushed which is present in large pieces, for example anode blocks, can be comminuted with a good crushing efficiency without the risk of the crushing jaw becoming blocked. <IMAGE>
