Title: Code-reading systems
IPC: B61B1/00
Filed: 1973-02-14
Abstract: 1421411 Conveyer control; photo-electric card reader RAPISTAN Inc 14 Feb 1973 [14 Feb 1972] 7362/73 Heading B7N In an arrangement for controlling a load carrier 16 in a conveyer system, identification or routing information on a logic card 20 mounted on the carrier is read by trackside photo-electric apparatus 26, 28. The logic card 20 is formed with three slots 42a, 42b and 42c each having mounted therein nine movable blocks 44. The slots have a length of ten blocks so that the blocks can be moved to provide a block sized opening 40a, 40b, 40c in one of ten positions in each slot. A spring loaded detent bar having a sawtooth lower edge is provided above each slot and co-operates with the upper edge of each block to retain it in its manually set position. The card is read as it passes between a light beam generating unit 26 and a light beam sensing unit 28. The generating unit is provided with a face plate 70 having three rows of openings 72 each dimensioned for receiving a light beam generator and disposed in a position corresponding to a possible opening in the logic card. The sensing unit is provided with a similar face plate with openings for receiving light sensors. Where the reader is used to control a track diverging element it is disposed ahead of the element and provided with a light source-light sensor combination in each row in positions uniquely defining the element. The reader then identifies load carriers with cards having similady disposed openings and actuates the element to divert these carriers. Reading of a card takes place when a first light source-light sensor combination in a position A detects aperture 38 on the card when a combination at a position B is cut off by the body of the card between rams 42b and 42c.

Title: Improvements in the manufacture and production of dyestuffs of the anthraquinone series
IPC: C09B1/20
Filed: 1933-03-11
Abstract: 1-amino-2-acetylanthraquinones having one or more sulphonic groups in the nucleus and/or in substituents are obtained, (I) by sulphonating 1 - amino - 2 - acetylanthraquinones; (II) by treating 1 - halogen - 2 - acetylanthraquinones with amino-sulphonic acids; (III) by introducing one or more amino groups into 2-acetylanthraquinones or their sulphonic acids, one amino group going into the 1-position; (IV) by sulphonating 2-acetylanthraquinones and introducing one or more amino groups as in (III).  In all cases the amino groups may be substituted. According to examples, (1) the following compounds are sulphonated: 1 : 4-diamino-, 1-amino-4-p-toluido-, 1-amino-4-m-toluido-, 1 - amino - 4 - anilido-, 1 - amino - 4 - p - anisido- and 1-amino-4-p-aminoanilido-2-acetylanthraquinones; (2) 1-amino-2-acetyl-4-brom-anthraquinone is treated with metanilic acid (see II above) or p-phenylene diamine, followed by sulphonating; (3) the starting material of example 2 is sulphonated followed by amination with p-toluidine.  Samples have been furnished under Sect. 2 (5) of products obtainable by sulphonating 1-amino-2-acetylanthraquinone, and the corresponding 1 : 5-diamino-compound.  The products, which may contain in addition to the 1-amino-group, other a - or b -amino groups, dye wool blue to green shades except in the case of the samples, which dye red shades. The starting-materials may be obtained as follows: 2-ethylanthraquinone is nitrated to give 1-nitro-2-ethylanthraquinone which on treatment with foaming sulphuric acid and reduction (see Specification 267,163, [Class 2 (iii)]) gives 1-amino-2-acetylanthraquinone.  Sulphuryl chloride gives the 4-chlor-derivative which may be converted with amines into the amino or arylamino derivatives employed in the examples. By dinitrating 2-ethylanthraquinone followed by oxidation of the ethyl group and reduction in one or two stages, the 1 : 5-dinitro-2-ethyl, 1-amino-2-acetyl-5-nitroanthraquinone, and 1 : 5-diamino-2-acetylanthraquinone are obtained.  By condensing 3 : 6-dichlorphthalic acid with ethylbenzene, and proceeding as above for the ethyl derivative, compounds containing two amino groups are ultimately obtained.  Acetylanthraquinones may also be obtained by treating anthracene with acetyl chloride followed by oxidation to the quinone.
Patent GB-482921-A (GB)
Title: Process for the production of cellulose derivative sheets or films
IPC: C08J7/04
Filed: 1937-03-15
Abstract: Transparent films or sheets of regenerated cellulose or cellulose derivatives having little or no tendency to stick together when in contact are obtained by incorporating in at least one surface of each of the sheets minute undissolved particles of uncolloidized cellulose derivative material, while maintaining the body of the film free from such particles.  The grains are preferably of substantially the same refractive index as the body of the sheet material.  A grainy dope containing the minute particles of uncolloidized cellulose derivative material may be coated on a sheet or film of cellulose derivative or regenerated cellulose, and it may be applied by spraying.  Preferably it is applied to the surface of the film before removal from the casting surface while the film contains a considerable amount of residual solvent.  The grains may be obtained by grinding cellulose tri-acetate and then adding the powder to the dope.  They may also be obtained by employing a cellulose ester produced under such conditions that it contains small quantities of highly esterified esters insoluble in the solvents to be used for film production. Grains which are partially soluble or slowly soluble in the film solvents may be used.  In an example, wood pulp squares are pretreated with acetic acid and anhydride at raised temperature and then acetylated by addition of acetic acid and sulphuric acid. Dilute acetic acid is added, and the cellulose ester is hydrolyzed at 100 DEG  C. for several hours, then precipitated, washed, and dried.  It is then dissolved in acetone or other solvent to give a grainy or hazy dope which may be added to other dopes.  The solution may be applied to cellulose acetate or nitrate sheeting. In another example nitrocellulose containing 12 per cent of nitrogen is subjected to hydrolysis with a warm solution of nitric acid, sulphuric acid and water.  The material is washed, and dissolved to form a grainy dope. Grainy dopes may also be prepared from cellulose formate, propionate, butyrate, phthalate, and stearate.  They may be applied to sheets or films of cellulose acetate, nitrate, acetate-propionate, cellulose methyl, ethyl, or benzyl ether, or regenerated cellulose. Specification 424,250 is referred to.  The Specification as open to inspection under Sect. 91 comprises also the use of dopes containing natural or synthetic resins, the production of films by casting grainy dopes so that the grains are distributed throughout the body of the films, and the production of grainy dopes by adding non-solvents to solutions of resins or cellulose derivatives.  This subject-matter does not appear in the Specification as accepted.

Patent GB-710737-A (GB)
Title: Improvements in or relating to the refining of fatty oils
IPC: C11B3/02
Filed: 1952-03-27
Abstract: Prior to the alkali refining of a gum-containing fatty oil there is admixed with the oil an aqueous solution of a polybasic aliphatic acid in amount sufficient for the added water to combine chemically with the gums therein, the solution being of a concentration such that the amount of acid on a dry basis admixed with the oil is at least 0.01 per cent. by weight of the oil.  The oils are thus conditioned, before the alkali refining, by the action of the polybasic acids on the gums therein, which enables them to release their content of absorbed oil.  The oil is then treated in the usual manner with an alkaline agent to precipitate the free fatty acids as soapstock with the colour bodies and the gums.  The amount of acid admixed with the oil preferably ranges from 0.075 to 0.125 per cent. by weight of the oil.  The polybasic aliphatic acids specified comprise citric, tartaric, maleic, malic, oxalic, itaconic, aconitic, tricarballylic, fumaric, succinic, glutaric and adipic acids.  The alkaline agent is preferably caustic soda, particularly caustic soda of high B<\>ae., such as at least 20 DEG  B<\>ae. concentration.  The amount of caustic soda is just sufficient or slightly in excess of that necessary to neutralize the free fatty acid content of the oil. The precipitate may be removed from the refined oil by gravity settling in a batch process or by a centrifugal separator in a continuous process.  A re-refining treatment with caustic soda of at least 20 DEG  B<\>ae. concentration may follow.  The oil may be heated before or after the addition of the alkaline refining agent. The gum impurity includes resins, phosphatides, mucins and carbohydrates.  Animal, vegetable and marine oils and fats may be treated, particularly oils obtained from cottonseed, sesame, sunflower, corn, soybean, coconut, palm, peanut, lard, whale, fish, fish livers and tallow.

Abstract: 1,255,941. Welding by pressure. MARCONI CO. Ltd. 14 Jan., 1969 [19 Feb., 1968], No. 7928/68. Heading B3R. [Also in Division H1] In a process for manufacturing microminiature integrated or similar circuit arrangements wherein two or more aluminium conductors mounted on electrically insulating substrates are required to be electrically and mechanically bonded, such bonding is achieved by pressing the conductors directly together and raising the temperature of each by the application of an external source of heat to a value at which bonding takes place without substantial deformation of any of the conductors. In bonding the raised pads 6 of aluminium conductors 1 on a glass substrate 2 to the aluminium conductors 3 on a silicon substrate.4, the substrates are pressed together with-the conductors in contact by pressing tools 7, 8 and the tool 7 is heated, preferably to at least 450‹ C. Although both tools may have planar pressing surfaces, where one substrate is substantially undeformable a probe with a rounded tip maybe used, as shown, to press that substrate. The pressure is preferably 20,000 p.s.i. Although both sets of conductors may be heated to the same temperature, it is stated that a better bond results when one set is at a slightly higher temperature than the other. A theory explaining the working of the process is advanced.
