Title: An improved shear-blade control mechanism
IPC: B23D21/00
Filed: 1964-08-04
Abstract: 1,009,638. Shearing. COMPAGNIE DES ATELIERS ET FORGES DE LA LOIRE (St. Cnamond-Firminy-St. Elienne-Jacob-Holtzer). Aug. 4, 1964 [Oct. 11, 1963], No. 30557/64. Heading B3W. In a shear the moving blade is subject to the action of a member which applies to the blade a force which varies according to its position and is characterized in that the member is an oscillating member having a surface which rolls without slip on a track rigidly attached to the frame, thus constituting a lever, the ratio of the lever arms varying according to its position, the action of this lever controlling the travel of the moving blade according to a law determined by the shapes of the rolling-contact surfaces. A fixed blade 1 co-operates with a moving blade 3 on a holder 4 pivotally connected at 5 to a link 6. The upper end of the link is pivotally connected at 7 to a lever 8 which in turn is pivotally connected at 9 to the piston 10 of a fluid cylinder 11. On each side of the central portion of the lever 8 are curved surfaces 17 which engage a flat surface 18 which forms the fulcrum for the lever. As the lever rotates, the contact point between the surfaces 17 and 18 moves along the lever so that the ratio between the arms of the lever varies according to its position relative to the track 18 and the shape of the contacting surfaces. The surfaces are held in contact by a spring assembly 19. There is a spring-loaded hold-down 25 and a driven roller-table 26 which can be swung about a pivot 28 when the cut has been made. The whole machine can move on rollers 33.

Title: Process for dyeing or printing cellulose-containing textile materials and compositions suitable therefor
Filed: 1952-12-02
Abstract: In the dyeing or printing of cellulose-containing textile materials there is employed a neutral to alkaline dyebath or printing paste containing (1) a direct dyestuff in which cobalt, nickel or copper is bound in complex union to at least one ortho-oxy-ortho1-carboxyazo-grouping; (2) an aliphatic a -aminocarboxylic acid, and (3) phosphorus-containing anions of a phosphoric acid of the constitution Hm+2PmO3m+1 in which m is a whole number greater than 1.  Specified amino-acids are alanine, sarcosine, glycocoll and b -oxyethylaminoacetic acid.  Phosphorus-containing anions may be derived from alkali salts of pyrophosphoric acid and of the polyphosphoric acids H5P3O10 and H6P4O13.  The bath or paste may also contain urea, saccharose and dextrin.  Dyeings or prints may be after-treated with the reaction products of formaldehyde with cyanamide, dicyandiamide, dicyandiamidine or melamine.  Numerous examples are given.

Title: Improvements in and relating to the production of oxygen-containing organic compounds
Inventor: DUNCANSON LEONARD ANDREW
IPC: C07C51/245
Filed: 1962-08-09
Abstract: The co-oxidation of a paraffin of a cycloparaffin together with a saturated aliphatic ketone containing an alpha-methylene group is effected by bringing the compounds together at a temperature of 50-200 DEG C. in the presence of molecular oxygen.  The paraffins and cycloparaffins are converted to oxygen-containing compounds, chiefly alcohols, ketones and carboxylic acids.  The alpha-methylene group referred to is a -CH2- group which does not form part of a methyl group.  Ketones which may be used as starting materials are, for example, methyl ethyl ketone, n-pentanone-2 or -3 and 2,5-hexanedione, The process may be carried out in the presence of a diluent, e.g. a carboxylic acid such as acetic acid.  Preferably the process is carried out in the presence of at least one salt of one or more metals of variable valency, e.g. salts of cobalt and/or manganese.  Initiations may be used instead of or in addition to the salts. The initiator may be ultra-violet light, ozone or a peroxide, e.g. an alkyl hydroperoxide or a dialkyl peroxide, a ketone peroxide, a diacyl peroxide, a dialkyl peroxy dicarbonate or a peroxy ester. There may also be present in the reaction mixture an aldehyde, e.g. acetaldehyde, when methyl ethyl ketone is used.  Water may also be present.  The process is preferably carried out at 80-140 DEG C. at atmospheric or super-atmospheric pressure.  The gas containing oxygen may be oxygen itself, air, mixtures of nitrogen and oxygen or oxygen diluted with carbon dioxide or the hydrocarbon to be oxidized.  The reactor may be made of aluminium, "Staybrite" (Trade Mark), tin, glass, porcelain, enamel or resins if no halide is present.  When a halide is present the reactor is desirably made or lined with titanium.  Examples are given of the oxidation of cyclohexane and n-octane.

Title: Improvements relating to Fluid Logic Systems
Inventor: BROWN COLIN CAMPBELL
IPC: F15C1/10
Filed: 1966-07-07
Abstract: 1,166,831. Pure fluid oscillators; pulse shapers. BRITISH AIRCRAFT CORP. Ltd. Aug.14, 1967 [July 7, 1966], No.30630/66. Heading G3H. A wall attachment type fluid element B has a capacitance C a connected to control channel J, so that fluid passing along outlet O2 aspirates the capacitance to a point where it changes the power flow to outlet O1 An oscillator is formed from a pair of these elements B, C which are fed alternately by a third element A through delay lines G1, G2, there being cross connections between the outlets of element A and control channels J2 of elements B and C via orifices D and E. Elements A and B are mono-stable with a bias to outlets O1 and O2 respectively, whilst element C is bi-stable. In operation application of pressure X to element A causes flow via outlet O1 to inlet I of element B which then produces an output at Y1 via its outlet O2. Simultaneously pressure is applied via orifice E to control channel J2 of element C thereby pressurizing the capacitance of this element. After a time determined by the volume of the capacitance of element B, flow is switched from ¢ to control channel J1 of element A thereby switching the output of element A to the input of element C where, due to the pressure in capacitance Ca a flow is established to outlet Y2 via O2. This flow is maintained until the capacitance of element C has been aspirated whereafter flow is directed via outlet O1 to control channel J2 of element A to recommence the cycle. Fig. 2 (not shown) illustrates a similar oscillator in which the cross connections are dispensed with, and elements B and C are both mono-stable with a bias to outlet O2. This oscillator operates by direct aspiration of the capacitances. A further embodiment Fig.4 provides a pulse shaper in which an element H with a capacitance Ca has its control channel J2 connected via orifice D to outlet O1 of element F1 the outlet O2 of which is connected via delay G3 to the input of element H.

Title: Process of making a wettable and dispersible flour-containing food product
IPC: A21D6/00
Filed: 1959-09-10
Abstract: A free-flowing, porous, readily wettable and dispersible aggregated food product consisting completely or essentially of flour, is produced by applying moisture to individual particles of the flour, while dispersed in a treatment zone, to an extent sufficient to provide them with a moisture content of 20 to 50% (e.g. 35%), to render them sticky and mutually adhesive so that they form moist aggregates of random shape and size, removing the moist aggregates from the treatment zone and relieving them of excess moisture, preferably to give a product of less than 14% moisture content.  The amount of moisture applied to the individual particles preferably is sufficient to render soluble the protein content of the flour product.  Flour products mentioned are cake, pie, bread, wheat, durum, rye, rice, barley, oat, corn and low- or full-fat soya flours, and bakery mixes including specified cereal flours, fats and egg solids, specified sweetening, flavouring, colouring and seasoning agents, milk solids (dry skim milk, sodium caseinate, lactalbumin or lactoglobulin), leavening agents such as sodium bicarbonate and monocalcium acid phosphate, and salt, brewer's yeast, coconut cereal meal, farina, and wheat or soya flour gluten.  Examples ascertain that the treatment does not give rise to alterations in the functional properties of the protein in the flour product.
