Title: Meat processing
IPC: A22C18/00
Filed: 1974-07-25
Abstract: 1431125 Separating lean and fat meat photoelectrically SORTEX CO OF NORTH AMERICA INC 25 July 1974 32884/74 Heading A2U [Also in Division G1] Meat is sorted into lean and fat portions by subjecting it to a process Which tends to separate fat and lean, cutting it into chunks, detecting an optical property of the meat related to lean meat content and sorting the meat in accordance with the detected value. The meat is initially separated by extrusion through a die. The optical property measured is reflectivity of both sides as the chunks fall through a detection zone.  As shown, meat pieces 10a are fed to hopper 14 of extruder 16 and, on emergence, are cut into chunks 10c of “" to 1" diameter. The chunks are fed to hopper 37 of refrigerated (26-32‹F) enclosure 78 and via vibratory tray feeder 40, multichannel chute 50 and multichannel belt conveyor 52 to photometric sensing unit 60. The sensing unit comprises tubular sources 64 and two rows 62, 63 of photocells; one cell of each row for each conveyor channel. A plurality of air blowers 66 are used to project selected chunks onto conveyor 74 instead of the normal conveyor 70. The photocells sense the reflected signal from both sides of the meat, their output being directly proportional to fat content. Their outputs may becombined in either AND orOR relationship and are fed, optionally via an inverter, via a delay to the associated blower 66. Fat pieces can be rejected when either photocell output exceeds a predetermined value or, in another method of operation, lean pieces can be blown out onto conveyor 74 only when the output of both photocells is below the predetermined value.

Patent GB-639964-A (GB)
Title: Improvements in and relating to the stabilisation of aldehydes
IPC: C07C45/86
Filed: 1947-12-19
Abstract: Aliphatic aldehydes (other than formaldehyde) are stabilized by incorporating therein a small amount of a monohydric phenol containing two or three substituent alkyl groups.  The aldehyde may contain from two to nine carbon atoms, specified aldehydes being acetaldehyde, iso- and n-butyraldehydes (obtained from propene, carbon monoxide and hydrogen in the presence of a catalyst) and nonyl aldehydes (especially the mixture containing 3 : 5 : 5-trimethyl-hexyl aldehyde obtained from diisobutylene with carbon monoxide and hydrogen).  The phenol has preferably at least one of the o- and p-positions substituted by alkyl and desirably both o-positions so substituted.  Specified phenols are 2 : 4-, 3 : 4- and 2 : 6-dimethyl-phenols, 2 : 3- and 2 : 4-dimethyl-6-tertiary butyl-phenols, 4-methyl-2 : 6-di-tertiary butyl phenol and 2 : 4- and 3 : 4-dimethyl-6-octyl-phenols, the octyl group being a  : a  : g  : g -tetramethyl-butyl.  In general, the alkyl substituents are preferably all in the o- and p-positions and in the case of tri-alkylated phenols one of the alkyl groups is preferably tertiary. Quantities of the phenols up to 1 per cent by weight may be used, but 0.03 per cent to 0.1 per cent are usually satisfactory.  In the absence of added phenols, p  the aldehydes are easily oxidized by air to give acid-reacting products, and this oxidation may be accelerated by the material of the container.  Examples show the stabilization of nonyl aldehyde and of a mixture of n- and iso-butyraldehydes.
Patent GB-636287-A (GB)
Title: Improvements in preparation of keto-carboxylic acids and their derivatives
IPC: C07C59/347
Filed: 1947-12-19
Abstract: Keto-acids or their derivatives are obtained by reacting aldehydes with olefinic carboxylic acids or their derivatives in the presence of a source of free radicals, the aldehyde being a n-alkanal, sec-alkanal, cycloalkane-aldehyde, aralkanal or aromatic aldehyde; when an unsaturated acid is used, the corresponding keto-acid is formed, and when a hydrolysable derivative of the acid is used, the corresponding derivative of the keto-acid is formed.  The source of free radicals may be ultra-violet rays, which produce the radicals by photochemical action on the reaction mixture, or a catalyst which yields free radicals at the reaction temperature.  Preferred catalysts are organic peroxides such as dibenzoyl peroxide; others are hydrogen peroxide, organic hydroperoxides, inorganic per-salts, hydrazine compounds (organic and inorganic) and organo-metallic compounds, but not Friedel-Craft catalysts; suitable compounds are mentioned. An inert diluent may be present.  Suitable aldehydes, olefinic acids and their derivatives are given, the latter including esters, nitriles, amides, anhydrides and halides.  Preferred olefinic compounds are those where the double bond is at the end of the chain and/or in the alpha position to the carboxyl group or its derivative and where at least one of the doubly-linked carbon atoms has a hydrogen atom attached thereto.  The products have the formula R-CO-(X)n-H, where RCHO is the aldehyde used, X is the divalent radical obtained by opening the double linkage of the olefinic compound, and n is an integer from 1 to 5, depending on the proportions of reactants used, the aldehyde preferably being always present at least in an equimolecular amount.  The reaction temperature may be from 25 DEG  to 150 DEG  C. preferably 60 DEG  to 100 DEG  C., using super-atmospheric pressure if the reactants have too low a boiling point.  The products may be isolated by fractional distillation or fractional crystallization of the reaction mixture. Examples show the production of (1) diethyl a -butyro-succinate from diethyl maleate and n-butyraldehyde; alkaline hydrolysis of the product yields 4-keto-heptanoic acid; (2) diethyl a -butyro-succinate from diethyl furmarate and n-butyraldehyde; (3) 12-keto-tridecanoic acid from 10-hendecenoic acid and acetaldehyde; the product may be converted into its semicarbazone; (4) methyl 12-ketotridecanoate from methyl undecylenate and acetaldehyde; (5) methyl 4-keto-heptanoate from methyl acrylate and n-butyraldehyde; the product yields a 2 : 4-dinitrophenylhydrazone.

Patent GB-1471745-A (GB)
Title: Method of automatically steering a vehicle
IPC: G05D3/14
Filed: 1974-07-31
Abstract: 1471745 Automatic steering ROBERT BOSCH GmbH 31 July 1974 [1 Aug 1973] 33706/74 Heading G3R A vehicle is automatically steered to follow a guide track defined by an alternating electromagnetic field by a system in which differential voltages induced in two respective pairs of coils 1, 2 carried by the vehicle, at front and rear, are added, are directly, the other inverted, at a summing point S together with a third feedback, voltage VG derived from a steering angle transducer 36, the summed voltage Us being compared with the output of the steering angle transducer to form a steering control voltage U ST , for steering motor 33. The voltages are such that straight line travel corresponds to a voltage from S equal to half the supply voltage. The coils 1, 2 are connected to S through devices 3, 4 which derive the differential voltages from the coil pairs, "on course" being equal to half the supply; these are connected as shown to operational amplifiers 6, 21, the latter of which carries out the inversion. A potentiometer 29 provides for proportioning between the front and rear differential voltages. A further operational amplifier circuit 16 adds an error rate term to the point S. The amount of feedback voltage UG can be adjusted at 40. In a modification, Fig. 2 (not shown) the feedback is automatically increased with increasing vehicle speed for steering angles above a speed dependent limit by a circuit including further operational amplifiers connected to the feedback circuit through diodes and receiving the output of a tachogenerator. When the amplified tacho.voltage is above the feedback level the diodes block and no modification is made, but when the feedback voltage exceeds that of the tacho, on tight turns, the diodes conduct so that the tacho voltage is added to that of the steering angle feedback. The characteristic of the tacho. may be modified, possibly to be made non-linear, by a circuit illustrated in Fig. 5 (not shown).

Title: Process for the resolution and recovery in the pure state of hydrazides and amides of dl-lysergic acid or dl-isolysergic acid
IPC: C07D457/06
Filed: 1955-11-24
Abstract: Amides and hydrazides of DL-lysergic acid and DL-isolysergic acid are resolved and recovered in the pure state by conversion into salts of acids HOOC-CH(OCOR)-CH(OCOR) -COOH, where R is an a b -unsaturated alkyl group, separation of the salts by fractional crystallization and treatment with alkali; the invention includes the salts themselves.  The salts can be obtained by mixing solutions of the components in water-miscible solvents, followed by addition of water if necessary, or by double decomposition, e.g. between the barium salt of the acid and the sulphate of the base.  An example is given of the resolution of DL-isolysergic hydrazide with di-(b b -dimethylacroyl)-L-tartaric acid, and other suitable acids are acroyl-tartaric and crotonoyl-tartaric (see Specification 772,215). The process is stated to be applicable also to the alkylamides, dialkylamides, hydroxyalkylamides and polyhydroxyalkylamides of lysergic and isolysergic acids. Specifications 453,531 and 573,514, [both in Group IV], also are referred to.

IPC: G03F7/027
Filed: 1961-09-21
Abstract: 926,583. Photographic polymeric images. GENERAL ANILINE & FILM CORPORATION. Sept. 21, 1961 [Oct. 10, 1960], No. 33858/61. Class 98 (2). A positively operating method of producing resist images comprises exposing a composition of an ethylenically unsaturated polymerizable compound, a colloid carrier and a diazo compound; applying a salt of a divalent metal in its lower oxidized state and a per compound having the grouping -O-O- to effect polymerization in the unexposed areas only, and removing unpolymerized photo-sensitive composition in the exposed areas. It is conjectured that the exposed diazo compound inhibits polymerization in the presence of this salt and per compound. Either of these may be initially present in the composition, thus in Example I a composition comprising gelatin, citric acid, N,N<SP>1</SP>-methylene-bis-acrylamide, ferrous ammonium sulphate and the zinc double salt of diazotized N,N<SP>1</SP>-hydroxy diethyl p-phenylenediamine on a polycarbonate base is exposed for two minutes through a positive transparency, treated in hydrogen peroxide solution and then bathed in warm water, to leave a positive resist which may be dyed with naphthylamine black. Example II describes the procedure with a composition omitting the ferrous ammonium sulphate, for application of this after exposure and following with hydrogen peroxide; and Examples III, IV have further slight variations. Extensive lists of the several materials used are provided, and uses of the method include multicolour procedure by superimposition, and especially printing plate production of which many types are referred to.
