Title: Penicillin manufacture
Inventor: DOBSON JAMES
IPC: C07D499/00
Filed: 1947-10-13
Abstract: Alkali or alkaline earth metal salts of penicillin are prepared by first forming the N-ethylhexamethyleneimine salt of penicillin by treating crude penicillin with N-ethylhexamethyleneimine in an organic solvent in which the N-ethylhexamethylene salt is soluble, e.g. chloroform, tetrachloroethane or methylene chloride, evaporating off the solvent, adding a solvent in which the N-ethylhexamethylene imine salt is insoluble, e.g. ethyl acetate, acetone, methyl ethyl ketone, benzene or carbon tetrachloride, filtering off the N-ethylhexamethyleneimine salt of penicillin and converting it into the alkali or alkaline earth metal salt by known means for converting an amine salt of penicillin into an alkali or alkaline earth metal salt.  Preferably an organic liquid of higher boiling point than the solvent which is being evaporated and in which the N-ethylhexamethyleneimine salt of penicillin is substantially or completely insoluble is added to the mixture before evaporation is complete.  Such liquids are cyclohexanol, cyclohexanone, benzyl alcohol, nitrobenzene, amyl acetate, n-butanol, the amyl alcohols, b -ethoxyethanol and xylene.  Preferably a quantity of N-ethylhexamethyleneimine approximately equivalent to the amount of penicillin present is used.  In examples: (1) N-ethylhexamethyleneimine and cyclohexanol are added to penicillin in chloroform, the chloroform is removed by evaporation, ethyl acetate is added, the precipitated N-ethylhexamethyleneimine salt of penicillin is separated by filtration, dissolved in water, acidified and extracted into amyl acetate and aqueous sodium bicarbonate added to give sodium penicillin which is separated by freeze drying; (2) the process of (1) is repeated using tetrachloroethane as the solvent for the impure penicillin and acetone as the precipitating solvent; (3) the process of (1) is repeated using methylene chloride as the solvent for the impure penicillin and the N-ethylhexamethyleneimine salt of penicillin obtained is converted into the calcium salt; (4) the process of (1) is repeated using methyl ethyl ketone as the precipitating solvent; and (5) N-ethylhexamethyleneimine and nitrobenzene are added to penicillin in chloroform, the chloroform is removed by evaporation and benzene is added to precipitate the N - ethylhexamethyleneimine salt of penicillin.  Specification 607,004 is referred to.

Title: Improved manufacture of hollow bricks closed on all sides
IPC: B28B11/00
Filed: 1922-10-10
Abstract: 187,956. Treitel, H., and Kammerziegelges. Oct. 26, 1921, [Convention date]. Moulds; pressing plungers and dies; extrusion machines; processes. - Hollow bricks closed on all sides are obtained by first moulding the brick with one end open and with burrs on the walls at the open end, and then pressing together the burrs until they meet. The mould 2 is partially filled with material m and covered with a plate 3 so that lateral spaces ware formed. A plunger 4 is then forced into the mould until the spaces w are filled as shown in Fig. 2. The brick is then closed by side plungers 5, Fig. 3. Additional pressure may be obtained by using a plunger 8 with a ridge as in Fig. 6 and by making the plungers 5 smaller than the spaces w, the top of the brick being subsequently cut off level and the burrs v stripped off during ejection. Fig. 7 shows apparatus adapted to form bricks from clay extruded from a press 9 over a mandrel 10, burrs 11 being formed by notched rollers 12 and pressed together by rollers 13 or stamps. A further modification is shown in Fig. 8 in which press members 16 which may move with the clay are reciprocated so as to first allow thickened wall portions to be extruded and subsequently to press said portions together. Alteration in the speed of the extruded strip is allowed for by corresponding alteration in the speed of reciprocation of the members 16 or by regulating the pressure inside the press by means of a conduit 18.

Title: Dough divider
IPC: A21C5/00
Filed: 1932-10-04
Abstract: 402,220. Dividing dough. SCHMIDT SECURITIES CO., 38, South Dearborn Street, Chicago, U.S.A. Oct. 4, 1932, No. 27507. Convention date, Oct. 5, 1931. [Class 87 (ii).] Portions of dough are segregated at the end of a flexible conduit by flattening the conduit by means of a pressure roller and then running the roller along the conduit to extrude the segregated portion. In the illustrated construction, dough treated under pressure in a chamber 10 in the manner described in Specification 368,396, [Group VI], is passed through an outlet pipe 20 into the flexible conduit 19, for example a composite rubber tube, which rests on the table 1. The outer end of the conduit 19 is closed at intervals by being flattened against the table by the lowering of the cross-bar of an inverted U-shaped member 30 which is latched automatically at 33 in its lowered position. While thus closed, the conduit is charged from the chamber 10. A pair of arms 84 carrying a cross-bar furnished with rollers 87 at each end is moved in an arcuate path by a pair of motordriven gearwheels 63, so that the rollers rotate round the interior of the casing 72 and pass right round the pivoted pawls 77 during the process. On the forward stroke the rollers 87 pass under the pawls and tilt them upwards against the action of springs 80, but the action is insufficient to prevent the tube being flattened as the roller passes along. Prior to this a cam 89 on the wheel 63 depresses a lever 50 and releases the latches 33 so that the mouth of the conduit is freed to allow the segregated portion of dough to be pushed out. At the extreme forward end of its travel the roller contacts with and re-sets the member 30 in its lowered position before making its idle return stroke over the top of the pawls. The whole of the driving-gear and the casings 72 and 52 may be moved longitudinally by rack-andpinion gear 57 relatively to the table, conduit, and the member 30 so as to vary the quantity of material segregated at each stroke. The forward end of the table is pivcted at 24 and supported on springs so as to yield in the event of excessive pressure due to obstruction in the conduit 19.

Abstract: 521,590. Coating &c. compositions. ARNOLD, C. (Standard Oil Development Co.). Sept. 23, 1938, No. 27827. [A Specification was laid open to inspection under Sect. 91 of the Acts, July 19, 1939.] [Class 95] [Also in Group IV] Compositions for coating, binding, waterproofing and insulating are prepared by swelling, but not dissolving, natural or synthetic rubber in a solution of paraffin wax, lubricating oil, petrolatum or polymers of aliphatic olefines or diolefines, or mixtures of these materials, in a volatile organic liquid capable of swelling but not dissolving the rubber at the temperature of treatment, the amount of solution being sufficient to give the final composition a spreadable consistency. Specified solvents are gasoline, naphtha, benzol, toluol, other hydrocarbons, and certain esters, ethers and ketones, and specified olefine polymers are poly-isobutylenes having molecular weights between 1,000 and 10,000. The swollen jelly-like rubber aggregates may be mechanically comminuted, e.g. by forcing through a wire mesh. Other optional ingredients are halogenated hydrocarbons as fireproofing ingredients, amino- or hydroxy-organic compounds or other anti-oxidants, substances which absorb the actinic rays of light which tend to destroy rubber, dyestuffs, and finely divided solids such as carbon black. Examples are given of waterproofing compositions containing : (1) paraffim wax, rubber and gasoline; (2) paraffin wax, rubber and naphtha. The compositions of this invention may be used for waterproofing cloth, paper or wood by coating, for preventing the corrosion of metals or the deterioration of rubber goods such as tyres and rubber raincoats, and as insulating materials for electric wires, cables and condensers.

Title: Improvements relating to sausage filling apparatus
IPC: A22C11/06
Filed: 1925-11-06
Abstract: 264,945. Wright, R. H., and Crozier, S. J. Nov. 6, 1925. Presses; cylinders; framing and mounting; working valves.-In a sausage-filling machine wherein the ram of the filling cylinder is operated by an hydraulic piston, the hydraulic valve is connected with control means so adapted that, on release, the valve is moved automatically to shut the inlet and outlet ports. As shown in Fig. 1, the cylinder 5 is supplied with water from a valve chest 7 having an inlet 7<a>. The valve 6 is kept against its seating by a spring 6<a> and is carried by a rod which is under the influence of a spring 8 which tends to move the valve to the right and, in the limit, to put the inlet port 5d in communication with the exhaust port 5<c>. A foot lever 9, having a spring-actuated catch 10<a> thereon, is connected to the valve rod and when it is depressed moves the valve to the left. When the pedal is depressed to the dotted line position, the catch 10<a> engages a projection 11<a> on a member 11 and the inlet port 5d is closed. Further depression opens the inlet port and the piston 4 rises. If the operator removes his foot, the pedal 9 rises until the catch 10<a> engages the projection 11 and the piston 4 becomes stationary. To allow the piston to return by gravity, the catch 10 is disengaged and the pedal is allowed to rise to its upper position. In a modification which is more suitable for horizontal cylinders, the piston is return hydraulically, an inlet port being provided for each side of the piston and the exhaust port being centrally disposed. The inlet port 5d is preferably of triangular shape so that as the port is uncovered the rate of increase in the opening will gradually become greater and vice versa. The supports 18, 19 for the cylinder 5 are provided with grooves 18<a>, 19<a> to receive a large cylinder if the available water pressure renders it desirable. One of the Provisional Specifications states that the piston may be returned by spring or equivalent means.
