Filed: 1962-12-18
Abstract: A granular detergent composition contains 2% of a normal amide of fatty acids derived from middle-cut coconut oil, 17.5% of a mixture of sodium dodecyl benzene sulphonate and sodium tallow alkyl sulphate and 50% of sodium tripolyphosphate.ALSO:A normal amide of a fatty acid containing 8 to 18 carbon atoms is prepared by reacting ammonia, with agitation at 320 DEG  to 550 DEG  F. and at at least 1000 lbs. per sq. inch gauge pressure, with a C8 to C18 fatty acid, an anhydride thereof or an ester thereof with a C1 to C4 monohydric alcohol in the presence of water in an amount of 50% to 200% by weight of that amount of water required to saturate the equilibrium reaction mixture at the reaction temperature. The temperature and pressure are preferably adjusted to provide a relatively high concentration of ammonia in the liquid fatty phase and it is also preferable to maintain a single liquid phase during the reaction. The fatty acid reactant may be saturated or unsaturated and is preferably the methyl ester of middle-cut coconut oil.  The amides may be purified by, for example, flash distillation after first cooling the reaction mixture.

Title: Hydraulic motor supply systems
IPC: B60K25/00
Filed: 1975-11-21
Abstract: 1536667 Hydrostatic transmission control CESSNA AIRCRAFT CO 21 Nov 1975 [22 Nov 1974] 47933/75 Heading F2W In a hydrostatic transmission for motor vehicle wherein an engine driven pressure compensated variable displacement pump 14 supplies pressure liquid to various accessories and to a parallel variable displacement motor 12 of an auxiliary drive to the front wheels 17 of the vehicle, a valve 60 senses the pump delivery pressure 18 and controls the motor displacement to maintain a predetermined minimum pump delivery pressure. Pump delivery pressure is supplied through a line 53, reversing valve 90 and line 67 or 68 to one end chamber 65 or 66 of the valve 60. The pressure in the chamber 65 or 66 moves the valve spool 60 right or left to meter pressure liquid from the line 53 through line 82 or 80 to a servo cylinder 22 or 24 which increases motor displacement in the forward or reverse direction. When the pressure in the line 53 drops below the predetermined value, the spring 64 or 65 moves the valve spool 60 towards its central position to reduce motor displacement and thus increase the pressure in the pump delivery line 18 to the predetermined value to ensure adequate supply to the accessories. The reversing valve 90 is normally biased by a spring 86 to the position shown in which it supplies pressure liquid to the end chamber 65 to move the valve spool 60 right for forward drive. To reverse the transmission pressure liquid is supplied through a line 105 to the end of the reversing valve spool which moves left and supplies pressure liquid to the end chamber 66 of the valve spool 60. If the wheel 17 slips the increased flow through the motor 12 causes a pressure build-up in the motor return line upstream of a throttle 46. The pressure increase acts through a line 47 to move a flow control valve spool 40 left against the bias of a spring 43 to a position in which it supplies pressure liquid from the line 53 through the valve 60 to the normally vented servo cylinder 24 or 22 to reduce motor displacement and thus the torque on the wheel 17. The servo cylinders 22, 24 have two-part servo pistons (Fig. 2, not shown), one part of each piston abutting a stop in the zero displacement position of the motor.

Title: Specimen identification techniques
IPC: G06V30/10
Filed: 1964-11-26
Abstract: 1,028,288. Character recognition. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 26, 1964 [Dec. 4, 1963], No. 48029/64. Heading G4R. To avoid using unintelligible words from a character reader the characters are recoded such that each group of characters which may be confused is given a single code and the coded words are compared with words in a drum dictionary each having associated with it one or more corresponding possible words in the initial notation. In the illustrated embodiment alphabetic characters are read into an input register 2 (Fig. 1, not shown) in a binary 6-bit code and each character is re-coded, 6, into a one-intwenty code with confused characters such as O and D having the same code 4 which is also represented in a binary 5-bit compacted code as 0100. The first letter of the word selects one of twenty drums in the dictionary 8 and each subsequent letter is compared with the letters of the words on the drum until an equality is reached. These words corresponding to the selected coded word are read into an output register 10 in the original 6-bits per character notation and the several words are compared sequentially at 14 with the word in the input register 2. When an equality is reached the selected word is read out sequentially through an output device 17 to a magnetic tape. If no equality is obtained and a zero detector 12 detects no further words in the output register 10 all the possible words are read out for examination by an operator. It may be arranged that the statistically most probable word is read out alone. If the input word contains any numbers the re-coding and drumdictionary circuit is by-passed and the word is read out immediately.

Title: Method of preparing porous material/synthetic polymer composites
IPC: C08F2/46
Filed: 1972-07-18
Abstract: 1450193 Porous material/polymer composites UNITED KINGDOM ATOMIC ENERGY AUTHORITY 16 Oct 1973 [18 July 1972] 48176/73 Divided out of 1449814 Heading C3P A composite material is prepared by polymerizing a polymerizable liquid comprising a monoethylenically unsaturated monomer or a mixture of such monomers in a porous material which does not comprise cellulosic fibre, the polymerizable liquid being in admixture, in the porous material, with a saturated aliphatic hydrocarbon or a halogen derivative thereof. The polymerizable liquid may include a crosslinking agent, e.g. divinylbenzene or a di- or trimethacrylate ester; an elastomer, e.g. polychloroprene or polybutadiene; a polymerization catalyst; and a dodecylmercaptan. Useful monomers include acrylonitrile, styrene, methyl methacrylate, vinylidene chloride, methyl acrylate, ethyl acrylate, butyl acrylate and vinyl acetate; styrene-acrylonitrile mixtures are preferred. The hydrocarbon or halogen derivative thereof is preferably an oily compound having 22 to 30 carbon atoms. Polymerization is suitably effected with radiation, e.g. accelerated electrons, ultraviolet radiation, X-rays, gamma rays or nuclear reactor radiation. The presence of the hydrocarbon or halogen derivative improves the fire-resistance and other properties of the composite material and, where polymerization is effected with radiation, reduces the dose of radiation required. Porous materials which may be treated include concrete, stone and fibreboard; the concrete composites can be used for pressure pipes and other articles normally made of steel, and the stone composites can be applied in wall cladding, flooring and external masonry. Other porous materials which are useful are finely divided inorganic materials such as powdered slate or chalk, or mineral waste dust; composites of these can be used as a dough for moulding or extruding, or as a potting material for electronic components.
