Title: Improvements in the saponification of materials comprising organic esters of cellulose
IPC: D06M11/38
Filed: 1934-01-13
Abstract: Filaments, threads, ribbons, &c. having a basis of cellulose acetate or other organic ester of cellulose are saponified by treatment in a bath containing a non-metallic base preferably a lower aliphatic amine, and in addition a nonhydroxy swelling agent.  Under these conditions, the materials can be saponified to a considerable depth in a relatively short time.  The cellulose acetate &c. of which the materials are made, may be of high viscosity characteristics, and the materials may further be such as have been subjected to a considerable stretching during or subsequent to manufacture. Suitable bases are: methylamine, ethylamine, propylamine, amylamine, triethylamine, trimethylamine, allylamine, tetramethylammonium hydroxide, ethylene diamine and other aliphatic diamines, 1.2.3-triaminopropane, a \su-diamino-b -hydroxy propane, and piperidine and other heterocyclic bases.  Suitable swelling agents are: acetone, methyl ethyl ketone, dioxane, methylene ethylene ether, cyclohexanone, and dimethyl ether of ethylene glycol; and also alkali thiocyanates.  The bath may be aqueous, or it may be made up with alcohol.  To accelerate the saponification, the bath may receive an addition of strong alkalies, or of heavy metals such as copper, silver, nickel or zinc as described in Specifications 430,349, 430,350, and 430,351.  The materials under treatment may be in the form of warps which are drawn through the bath; or in the form of hanks which are suspended in the bath; or as bobbins, cheeses or cakes; or made up into fabrics, employing for the treatment a machine of the winch type. The saponified materials may be stretched. Specifications 207,562, [Class 2 (ii)], 402,105, and 429,447 also are referred to; and in the Provisional Specification, Specifications 323,790, 340,324, 340,325, 340,326, 340,436, 340,437, 343,062, 370,430, 371,461, 378,858, 389,823, 411,094, 429,103, and 432,028.

Title: Vehicle auxiliary hydrostatic drive system
IPC: F16H39/02
Filed: 1975-01-13
Abstract: 1480031 Hydrostatic transmission control DEERE & CO 13 Jan 1975 [14 Jan 1974] 1392/75 Heading F2W In an auxiliary hydrostatic transmission driving the front steerable wheels of a tractor which has its rear wheels driven through a mechanical transmission wherein a variable displacement pump 22 supplies pressure liquid through a reversing valve 38 to fixed displacement axial or radial piston motors 20L, 20R, the motor casings are normally connected to a reservoir 24 through a valve 72 which, when the reversing valve 38 is in a neutral setting, connects the motor casings to the output ports of the motors to pressurize the casings when the motors are driven by the vehicle wheels and thus create a small pressure differential across the motor pistons to thereby reduce damage between the pistons and their associated cam or swash plates by reducing the period of contact therebetween. The pump 22 supplies pressure liquid through a line 36 and priority valve 52, which opens when the pressure upstream thereof exceeds a predetermined value, to the reversing valve 38. The valve 38 is spring biased to its neutral position and is moved to its forward or reverse position by pressure liquid supplied from the high pressure line 36 through solenoid operated pilot valves 88, 90 and lines 100, 110. The pressure in the lines 100, 110 is additionally supplied to opposite ends of the valve 72 which, when the reversing valve 38 is moved to its forward or reverse position, moves to a position in which it connects lines 68, 70 from the motor casings to a reservoir line 86. The motors 20L, 20R may be connected in parallel or in series by a valve 58 controlled by a solenoid operated pilot valve 92. When the pilot valves 88, 90 are both deenergized the valves 38, 72 are moved by spring to the positions shown. If under these conditions the vehicle wheels drive the motors 20L, 20R the pressure output therefrom in line 54 or 60 passes through a one-way valve 78 and the valve 72 to pressurize the motor casings. The pump 22 additionally supplies pressure liquid through a line 48 to power steering and braking mechanisms not described. The return line 40 to the reservoir contains a cooler 42 and is maintained at a predetermined low pressure by a throttle 46. In Fig. 3 (not shown) the valves 38 and 72 are combined as a single unit.

Abstract: 213,360. Walker, r. P., Walker, R. H., and Walker & Sons, Ltd., J. W. Jan. 16, 1923. Pneumatic actuation; plugboards.-A readily attachable and detachable unit device for electric organs comprises a pneumatic motor and electric contacts operated thereby, with means for connection to the pneumatic control and to the appropriate electric circuit. Fig. 1 shows the application of such units to a relav board with electromagnetic keycontrol. On depression of a key, wind in the chest l passes through the valve o to the vertical noteduct b and hence, provided the appropriate horizontal stop-slide k is drawn, to a unit z. The unit may consist of a body 1, Fig. 3, detachably supported by a metallic tubular spigot 6 which is inserted in the metal liner g of one of the ports f. All the liners g of a noteduct b are connected by a vertical bus-bar 10 to a source of electricity. In electrical connection with the spigot 6 is a blade spring 7 which on admission of wind to the chamber 5, is raised by a motor-membrane 3 into contact with a wire 8, completing the circuit to the magnet of the sounding-pipe by a spring 9, staple j with which the spring 9 automatically engages on pushing the spigot home, and cable 11. In the construction shown in Fig. 6 and 7, stop-ducts are used instead of the slides k. The stop-ducts 15 are secured to the vertical bus-bars 12 by metal liners 14, communicating with the note-duct b, each liner 14 receiving one of two metal spigots 22, 23 attached to the contact-unit, the other spigot being inserted in a liner 17 connected to the cable 11 and communicating with the interior of the stop-duct 15. The unit when detached may be opened book-wise on a leather hinge 27; when in position, the membrane 21 only rises to make contact between the wires 24, 25 when the stopduct 15 is connected to exhaust, the wind is admitted to the note-duct b as before. In another modification, the units are cylindrical and bodily insertable into the stop ducts, electrical connection between the upper contact-arm and a cable lead being made by a rotary movement ,of the unit when inserted.

Title: Improvements relating to electric lighting equipment for vehicles
IPC: H02K7/10
Filed: 1936-01-17
Abstract: 468,395. Hydraulic transmission of power. BRYCE, Ltd., and AYRES, J. Jan. 17, 1936, No. 1578. [Class 69 (ii)] [Also in Group XXXV] In electric lighting equipment for vehicles comprising a shunt wound dynamo driven from the engine or transmission, a hydraulic coupling of the F÷ttinger type wherein provision is made for automatically byepassing liquid from between the coacting driving and driven members of the coupling at a rate proportional to variations in speed of the driving member in excess of the normal speed is interposed between the dynamo and its drive for affording variable slip so that the dynamo is prevented from running above its normal speed and thereby generating more than normal voltages. The drive shaft carries the pump 7, Fig. 2, of a coupling ; the turbine comprises a part 11 secured to the armature shaft of the dynamo and a part 12 splined to the hub of part 11 for axial movement thereon, the parts 11, 12 being normally held in contact by a spring 13 ; when the speed of the driving member increases above that corresponding to the normal speed of the dynamo, the resulting increase in pressure in the coupling forces the part 12 away from the part 11 and liquid passes through the gap A thus opened to the space 16 behind the turbine, and back into the working circuit through ports 17; the speed of the dynamo is thus maintained constant. In a modification, Fig. 4, governor mechanism 27 ... 31 mounted on the driven shaft 4 acts through levers 32 on spring-loaded valves 22, so that when the speed of the driven shaft rises due to an increase in the speed of the driving shaft, the valves 22 are opened and liquid is byepassed through passages 24, 25, 26 whereby the speed of the armature shaft is restored to its normal value. Speed increasing gearing may be interposed between the driven part of the coupling and the armature shaft. The pump member of the coupling may carry fan blades for cooling the dynamo. Taper charging to the battery, that is, a heavy charge when the battery is discharged, tapering to a trickle charge when the battery is charged, may be effected by the inclusion of a compound winding on the dynamo in conjunction with the normal reverse cut-out.

Title: Improvements relating to the production of benzoic acid
Inventor: HARRIS ROBERT W
IPC: C07C51/42
Filed: 1957-01-16
Abstract: Pure benzoic acid is prepared by oxidizing toluene, subjecting the oxidation product to a fractional distillation to remove unreacted toluene, extracting this residue with water at a temperature between 95 DEG  and 100 DEG  C., filtering the solution free from residue and mildly oxidizing the solution of benzoic acid prior to crystallization.  The fractional distillation removes most of the volatile compounds in the mixture, e.g. unreacted toluene, and the extraction may then be carried out without foaming.  The benzoic acid is extracted preferably at atmospheric pressure and after separation from the organic residue the solution is oxidized with a reagent such as permanganate or hypochlorite.  The solution may then be treated with decolorizing charcoal and benzoic acid crystallizes out on cooling.  In examples, toluene is oxidized with air and a cobalt catalyst under pressure and portions of the reaction product are purified: (a) by heating until a fusion point of 90 DEG  C. is reached, extracting with water at 98 DEG  C., oxidizing with potassium permanganate solution and decolorizing with charcoal; (b) by heating until the residue solidifies at 95 DEG  C. and extracting counter-currently with water at 98 DEG  C., then as in (a); (c) as in (b) but with further extraction and oxidizing with hypochlorite.

IPC: C08G14/06
Filed: 1963-01-15
Abstract: The invention relates to vicinal epoxide adducts of uncatalysed condensation products produced from a phenol, an aromatic amine and an aldehyde.  Specified phenols from which the condensation products may be derived are phenol, alkylphenols having alkyl groups of 1-18 carbon atoms, halophenols, alkoxy- and dialkylamino-phenols and dihydroxybenzenes. Specified aromatic amines are aniline, benzene-diamines, alkyl-substituted anilines and benzenediamines having alkyl groups of 1-4 carbon atoms and N-alkylaminoanilines. Specified aldehydes are formaldehyde, acetaldehyde, propionaldehyde and chloral.  The molar proportion of phenol to aromatic amine may range from 15: 1 to 1: 15, and the molar proportion of phenol and aromatic amine to aldehyde may range from 6: 1 to 1.2: 1.  Specified epoxides for use in the addition reaction are alkylene oxides of 2-10 carbon atoms and their halogen substitution products, aryl glycidyl ethers, aryl-substituted alkylene oxides and cycloalkylene oxides. The proportion of epoxide reacted may range from 0.25 to 30 mols. per equivalent of reactive hydrogen atoms in the condensation product. Up to 1 mol. of epoxide per equivalent of phenolic hydroxy groups in the condensation product may be caused to react without the use of a catalyst, but the addition of further epoxide groups requires the use of a catalyst, e.g. an alkali or alkaline-earth metal hydroxide or alkoxide, a tertiary aliphatic amine, a quaternary ammonium or phosphonium hydroxide or alkoxide, a proton acid or a Lewis acid. The addition reaction may be effected at 100-220 DEG  C. and atmospheric, reduced or raised pressure.  The products may be used (1) as hardeners for polyepoxide resins, (2) in the manufacture of reaction products with polyethers such as polyoxyethylene, (3) as surfactants, ion-exchange resins and chelating agents and (4) in the manufacture of esters, useful as surface coatings, with drying-oil acids.  Examples are given of the manufacture of condensation products from several phenols and aromatic amines and formaldehyde, and of the reaction of these products with propylene oxide.  A further example is given also in which a phenol-aniline-formaldehyde condensation product is treated with ethylene oxide in the absence of a catalyst, and the product is then further treated with propylene oxide in the presence of potassium hydroxide as a catalyst.
