Title: Improvements in or relating to pulse count subtracting networks
Inventor: ARPA ANDREA D
IPC: H03K21/02
Filed: 1967-04-24
Abstract: 1,216,074. Counter input circuits. MARCONI CO. Ltd. 20 Feb., 1968 [24 April, 1967], No. 18721/67. Heading G4A. A buffer circuit for cancelling out alternating positive and negative counting input pulses and passing a pulse only when it is preceded by a like pulse comprises a number of triggerable JK flip-flops and NOR gates. A first pair of cross-connected JK flip-flops AJ1, BJ1 reverse (in either direction) alternately if positive and negative input pulses are applied to trigger terminals T from A and B, respectively, in succession. In these conditions at the end of a positive count pulse AJ2 reverses and NOR gates AN11, AN12, AN2 and inverter AV set AJ3 to produce 1 at its terminal Q, so blocking NOR gate AN3. If now a further pulse occurs at A (or overlaps a pulse at B) then AJ1 is held by the cross-coupling from BJ1 and inverter AV applies 1 to input K of AJ3. At the end of the pulse AJ2 holds and AJ3 applies O to AN3. The next A pulse is inverted at ATV so that NOR gate AN3 produces an output at AA. In like manner successive pulse at B produce an output at BB. If negative count pulses are infrequent the circuit can be simplified to have only one output.

Title: Improvements in methods of and arrangements for injection-moulding soles, for example of foamed synthetic plastics material, on to footwear uppers
IPC: A43B13/32
Filed: 1966-04-29
Abstract: 1,130,217. Boots &c. DESMA-WERKE G.m.b.H. 29 April, 1966 [17 May, 1965], No. 18813/66. Heading A3B. [Also in Division B5] Unexpanded material provided with expanding agents is injected into a mould with a bottom plunger 13 in a position (II) until movement of the bottom plunger downwards by a short distance into a position (III) actuates a shut-off mechanism 36 to stop the injection, the bottom plunger being finally moved into a position (IV) which corresponds to the final thickness of the sole and the material expands under the action of the expanding agents to completely fill the mould. An edge strip 16 of firm compact material may be injected first, with the bottom plunger 13 in a position (I) directly on the last 10 or on the shoe upper 11 or on an inner sole 14. A pre-set time delay before movement from position (III) to (IV) causes a compact layer to be formed on the outer part of the sole. The plunger 13 has a rod 30 passing through two coaxial pistons 25, 28. A sleeve 31 fixed to piston 25 slides within a sleeve 32 fixed to piston 28. The shut-off mechanism 36 has a pivoted lever 37 actuated by downward movement of the plunger rod 30. In position I pressure fluid applied below the piston 25 causes the plunger 13 to press a felt insert against the shoe upper or an inner sole 14 to secure the insert by means of adhesive. Piston 28 is in an upper position determined by an adjustable stop 35. Following formation of the edge strip 16, piston 25 is moved to position (II) by relieving conduit 27 and applying pressure through an upper conduit 26, the piston 28 being charged at a higher pressure than the piston 25 and thereby acting as a stop therefor. A shoulder 34 of the sleeve 31 seats on an upper flange of the sleeve 32, a distance 'h' being left between a shut-off piston 33 on the rod 30 and an upper flange on the sleeve 31. When the internal pressure is exceeded, the distance 'h' is taken up by downward movement of the ram, when the lower end thereof interacts with the lever 37 to overcome the pressure of a spring 38 and operate an electrical contact 39 to stop injection. After a time delay of 5-6 seconds, the piston 28 is relieved, so that piston 25 moves the ram 30 into the position (IV) through a distance 'e'. The formation of the compact, homogeneous outer layer of plastics material is facilitated by cooling the ram 13 to a specified temperature, the thickness of the layer also being controlled in this way. The injection sprue 19 may be closed in position (I) by a plate 42 and the edge strip 16 is formed in grooves 17 milled in a side frame 12.

Abstract: 666,614. Embossing-machines. TURNER TANNING MACHINERY CO., Ltd., and HALL, C. July 7,1950 [July 19, 1949], No. 18980/49. Class 100 (ii). [Also in Group VIII] In a machine for embossing leather, of the type comprising a fixed platen 1, a reciprocable carriage 8 furnished with a tool, e.g. a roller 9, and a flexible holster 11, the tool is adapted to be moved relatively to the carriage to and from the face of the platen. The reciprocatory travel of the tool is restricted to the effective length of the platen. The head of a double-ended piston 19 is arranged in a cylinder 18 mounted on the carriage 8, and the piston carries rods 23, 24 which are fixed to the sides of the machine. Hydraulic fluid, e.g. oil, is pumped from tank 31 by constant delivery pump 34 via control valve 3 and four-way reversing valve 39 through lines 29 or 30 and axial bores in the rods 23 or 24 to one side or the other of the piston head 19, effecting the reciprocating travel of the carriage. The roller 9 is raised by means of hydraulic fluid passing through branch lines 72 or 73 via valve 71 to cylinder 17 provided with a piston. The pressure of the roller on the work is regulated by means of control valve 36 and back pressure valve 45, and the speed of travel by flow control valve 44. When the carriage reaches the end of its movement in one direction, cam 55 attached thereto co-operates with a lever and linkage system 47, 48, 49 to set valve 39 to a neutral position, stopping the carriage and allowing roller 9 to descend; cam 58 is also moved to open bleeding valve 41 through which hydraulic fluid is by-passed back to the tank. The machine is set in motion again by operating one of the treadles 65, 66. A safety guard 74 is connected with the valve 39, so that the guard can be raised only when the machine is idle, and must be lowered before the machine is restarted.

Patent GB-796665-A (GB)
Title: Process for the preparation of indole carboxylic acids
Filed: 1957-06-20
Abstract: Indole carboxylic acids or salts or derivatives thereof are prepared by heating indole or a substituted indole which contains a hydrogen atom in the 2 and/or 3 position with carbon dioxide under pressure in the presence of an acid-binding agent.  The salts of indole carboxylic acids thus obtained, the carboxyl groups of which are in the 2- or 3-position, may be converted in known manner into the free acids or derivatives thereof.  The starting materials may be substituted in either or both rings, and may include: 1-, 2- or 3-alkyl- or aryl-indoles, 3-indolyl acetic acid, 1,3-dimethylindole (1-methylskatol), 4-methylindole, 7-methylindole, 2,5 - dimethylindole, 3,5 - dimethylindole, 2 - phenyl - 7 - methylindole, 1 - ethyl - 5 - methyl-indole, 2 - phenyl - 7 - methylindole, 5 - chloro-2 - ethylindole, 2,4,7 - trimethylindole, indole-carboxylic acid - 6, 4,5 - benzindole and 6,7 - benzindole.  Preferred acid-binding agents are basically-reacting alkali metal salts such as the carbonates, oxides, hydroxides, bicarbonates, formates or oxalates; particularly preferred is potassium carbonate.  The agent should be as anhydrous as possible, although small amounts of water do not disturb the reaction.  They are used in at least the quantity necessary for the formation of the carboxylic acid salt, but preferably in 10-100 per cent or more excess.  The temperature is generally 150-500 DEG  C., usually optimally 200-350 DEG  C.  At least the calculated quantity of CO2 is used, preferably an excess, the pressure reaching, for example, 10-500 atm.  The CO2 may be diluted by inert gases such as nitrogen. Catalysts may be present such as zinc, cadmium, lead, mercury or iron or compounds thereof such as the oxides or salts with inorganic or organic acids.  Inert fillers may also be used such as sand, finely-divided carbon, kieselguhr, bentonite, metal powder or chippings and inert salts such as sodium sulphate and potassium sulphate.  Organic diluents may also be added, e.g. pyridine, dioxan, tetrahydrofuran, benzene, toluene, xylene, and high-boiling benzines.  The reaction product may be worked up by dissolving in water, filtering, if desired with the addition of active carbon or other decolorizing agent; and liberating the desired acids by acidification, e.g. with HCl, H2SO4 or other strong acids.  In many cases the reaction products can also be isolated by utilizing the low solubility of the potassium salts in saturated K2CO3 solution.  Alternatively the crude reaction product may be directly converted in known manner to derivatives such as the chlorides or esters of the indole carboxylic acids formed.  The products are useful intermediates in the synthesis of pharmaceuticals and plant-growth promoters.  In examples, the following are prepared in the presence of K2CO3: (1), (2) and (3) indole-3-carboxylic acid from indole, CdF2 being present in (2) and (3); (4) skatol-2-carboxylic acid from skatol; (5) 2-methylindole-3-carboxylic acid from 2-methylindole, CdCl2 being present; (6) N-methylindole-2-carboxylic acid from N-methylindole.

Abstract: 314,350. Durand et Huguenin Soc. Anon., (Assignees of Livingston, J. C.). June 25, 1928, [Convention, date]. Fibrous materials and non-metallic fabrics, treating; non-metallic substances, obtaining and depositing.-The acid oxidizing action necessary for the development of dyeings and prints with ester salts of leuco vat dyes is obtained by means of electrolysis. For this purpose the material to be dyed may be padded with a solution of ester salt, squeezed and placed on a metal plate in the moist state. A drawing pencil or printing block of conductive material (resistant metal or carbon) forms the anode and is connected to a source of continuous current of about 4 volts E.M.F. The dyeing is developed wherever the material is in contact with the anode, so that local dyeings, drawings and dyeings of different intensity can readily be produced in fabrics. The ester salt may also be supplied to the drawing pencil so as to be applied to the fabric locally, and different ester salts may thus be applied on one and the same material, producing multi-coloured effects. In an example, cotton cloth is padded with a solution containing Indigosol O and ammonium sulphocyanide, placed on a metal plate, and the dyeing is developed by means of a conductive pencil forming the anode. The fabric is subsequently washed and soaped. Specifications 186,057 and 2.03,681, [both in Class 15 (ii), Dyeing, Processes &c. for], are referred to.
