Title: Improvements relating to anion-exchange resins
Inventor: KRESSMAN THEODORE ROGER ERNEST
IPC: C08F8/44
Filed: 1955-11-23
Abstract: Anion-exchange resins containing two or more nitrogen atoms in each anion-exchange group are prepared by reacting a cross-linked polymer containing halo-alkyl groups, e.g. chloromethylated cross-linked polystyrene or copolymers of polystyrene with divinyl benzene or ketone, with a o -mono or o -dialkylamino alkyl halide and an amine. The reaction may take place directly by mixing the three reactants, or in stages in which an intermediate is obtained (1) by reacting the polymer with the amino alkyl halide, preferably b -methyl amino or b -ethyl amino ethyl chloride, and then with a primary, secondary or tertiary amine to introduce secondary, tertiary or quaternary nitrogen atoms respectively; (2) by reacting the polymer with a primary or secondary amine and then with the alkyl halide derivative in the presence of a base, e.g. caustic soda.  The resins may combine weakly basic with strongly basic properties and may be further alkylated to convert secondary and tertiary groups to tertiary or quaternary groups respectively.  In examples, beads of a chloromethylated copolymer of divinyl benzene were swollen with benzene and reacted with b -diethylamino ethyl chloride at 30 DEG C., cooled, boiled and washed with dilute hydrochloric acid, and water to give an intermediate which was heated with di- or trimethylamine solution and washed to yield final resins containing a tertiary and quaternary or two quaternary nitrogen atoms respectively. Specification 779,994 is referred to.

Title: Brake regulators for motor vehicles
IPC: B60T11/24
Filed: 1969-07-04
Abstract: 1,245,523. Pressure regulators; valves. AISIN SEIKI K.K. 4 July, 1969 [5 July, 1968; 20 Aug., 1968], No. 33965/69. Headings F2F and F2V. A pressure regulator for a motor vehicle hydraulic braking system comprises a switchover valve for an hydraulic braking circuit whereby above a predetermined switch-over pressure only a proportion of any increase in an applied hydraulic pressure is adapted to be passed to an hydraulic brake assembly, and means for increasing the predetermined switchover pressure in response to failure of another hydraulic braking circuit of the braking system. As shown, the regulator 1 has an inlet 2 connected by a line 3<SP>1</SP> to a master cylinder 4, the inlet communicating with a chamber 7 receiving a spring-biased piston 8 the head 9 of which is formed with a compartment 12 connected by a bore 11 to the chamber 7 and having therein a spring-loaded valve 15 provided with a stud 17 engageable with the surface 18<SP>1</SP> of a plug 18 which surface forms with the surface 19<SP>1</SP> of the head 9 a chamber 19. A cylinder 33 connected to the regulator has therein a spring-biased piston 32 including a stem 31 engageable by the stem 30 of the piston 8, the cylinder having an inlet port 43. The dual master cylinder 4 is connected by the line 3<SP>1</SP> to the port 2 via which pressure fluid acts, through line 28, on one set of rear shoe brake cylinders 21 and one set of front disc brake cylinders 46<SP>1</SP>, the line 3<SP>1</SP> also being connected to the port 43<SP>1</SP> of a second regulator 1<SP>1</SP>. The master cylinder is also connected by line 3 to the inlet port 2<SP>1</SP> of the regulator 1<SP>1</SP> and via which pressure fluid acts through line 28<SP>1</SP> to a second set of rear shoe brake cylinders 26 and a second set of front disc brake cylinders 46, the line 3 also being connected to the inlet 43 of the regulator 1. Depression of the brake pedal 5 transmits fluid pressure from the master cylinder to the inlets 2, 2<SP>1</SP>, the fluid passing through the open valves 15 in the regulators to the rear wheel brake cylinders and directly to the front wheel brake cylinders and the pistons 8 moving to the right as seen in the Fig. 1 and against the force of the springs 35 whereby the valves 15 are gradually closed, additional force applied to the brake pedal resulting in displacement of the piston sufficiently to close the valves so that further displacement of the pistons in response to the application of additional pressure to the fluid does not result in substantial displacement of the pistons. The pistons 32 are displaced to the right in synchronism with displacement of the pistons 8. In the event of a breakage of one of the lines 3, 3<SP>1</SP>, the piston 32 of one or other of the regulators remains inoperative. In modifications, (a) two regulators 101, 101<SP>1</SP>, Fig. 3, cooperate to press a connector 159 against a single restoring spring 135, and (b) displacement of the pistons 8 of the regulators is retarded by the fluid pressure acting on an intermediate piston.

Title: Improvements relating to processes for the continuous casting of iron and steel
IPC: B22D11/07
Filed: 1953-12-08
Abstract: 750,196. Continuous -- casting machines. MANNESMANN AKT.-GES. Dec. 8, 1953 [Dec. 10, 1952], No. 34186/53. Class 83 (1). In a process of continuous-casting of iron and steel in a chill-mould, the mould is reciprocated relatively to the casting-head, and the casting is lubricated solely by introducing into the mould, above the casting head, at least one hydrocarbon or hydrocarbon-compound which has a high carbon content and rapidly decomposes under the influence of heat to produce on the mould wall, above the casting head, a deposit of carbon black which is caused by the relative movement to pass between the mould and the casting. The relative movement may be produced by axial reciprocation of the mould or, with the mould stationary, either superimposing on the casting a reciprocatory movement additional to its continuous sinking movement, or periodically changing the rate of flow of liquid metal into the mould. The hydrocarbon or hydrocarbon-compound may be a gas, e.g. acetylene, butadiene or propane, or a liquid, e.g. benzene, turpentine or trichlorethylene, or a solid, e.g. naphthalene or anthracene. Protective gases, which may be preheated, in the form of inert gases, such as argon or nitrogen, or combustible gases, such as dry carbon monoxide, or coke-oven gas, or a mixture of such gases, may also be introduced into the mould above the casting head.

Title: Improvements in the method of operating rotary drum drying machines
IPC: F26B11/04
Filed: 1945-12-18
Abstract: 605,221. Drying grass. HEENAN & FROUDE, Ltd., and WALKER, G. H. Dec. 18, 1945, No. 34237. [Class 34(ii)] Comprises a method of operating a rotary drum drying apparatus at a speed such that the force of gravity acting on the the drum is just sufficient to overcome the material in the top zone of the interior of centrifugal force on the material, so that the material cascades from the top to the bottom of the drum, and is thereby exposed to the flow of drying gases through the drum. Hot gases pass from a fan C and heating chamber F. to the drum 4, internal flights 4b pick up the material in the drum causing it to cascade from the top to the bottom of the drum. Dry material is carried through the drum by the passage of the drying gas to chamber 6 where a fan 7 discharges the gas and material together to a cyclone separator 10, The drying gases are exhausted via K' or may be partly re-circulated by means of pipe L communicating with the inlet of fan C. As an alternative to the fan 1 feeding of material to be dried may be by means of a hopper leading to chamber 3 of the drum, the throat of the hopper being sealed by spring-loaded rollers.

Title: Soy bean cooking machine
IPC: A23L11/30
Filed: 1972-07-22
Abstract: 1407473 Cooking soya beans KOEHRING CO 22 July 1972 34407/72 Heading A2Q [Also in Divisions A4 B1 and B5] A machine for cooking soy beans comprises a rotatably mounted shaft assembly having a spiral rib for conveying soy bean material along a housing assembly having intake and discharge openings, the shaft assembly being axially movable relative the housing assembly and a restricted clearance being provided between the spiral rib and the interior wall surface of the housing assembly, means for supplying soy bean material to the intake opening, and a metering opening defined by a projecting portion on the shaft assembly and a surface on the housing assembly, the restrictive action provided by the metering opening being such that the soy bean material is heated and cooked as it is conveyed along the housing assembly and discharged through the discharge opening and the metering opening, the metering opening being adjustable for regulation of the cooking of the soy bean material. In the embodiment shown the discharge opening is defined by a bore 48 in an end plate 42 of a housing 12 and an end portion 50 of a shaft 18. The metering opening is defined between a washer 52 and the end plate 42. A spiral rib 28 is provided on the interior wall surface 26 of the housing; in an alternative form the spiral rib 28 is replaced by straight longitudinal ribs. A generally ring-like wedge 60 is secured to the end of a cylindrical portion 22 of the shaft assembly. The wedge 60 has a varying width and thickness such that, during rotation of the shaft, the soy bean material is progressively compressed between the wedge and a collar 56. The soy bean material is thus substantially liquified by the application of heat and pressure, and is passed through the discharge opening and the metering opening. An auger assembly (32), Fig. 1 (not shown), feeds soy bean material from a hopper (40) to the intake opening (30) of the housing. A vertical hollow stack (12A) Fig. 3 (not shown), receives soy bean material in the event of excessive flow of soy bean material into the housing 12. A shield 66 is placed over the end of the shaft 18. Cleaning of the interior of the housing 12 is facilitated by removing a nut 54 retaining the washer 52 onto the shaft 18 and by removing the end plate 42. In the embodiment of Figs. 6, 7 and 8 (not shown), the interior wall surface of the housing (100) has elongated spaced ribs (102). The shaft (104) is tapered, having its larger end extending through a bore (132) in a plate (130) to define a discharge opening (134). The metering opening (140) is defined by the plate (130) and a washer (136). Rotation of a nut (128) at the intake end of the housing axially moves the shaft to adjust the metering opening. The shaft is mounted in a bearing (116) and held thereto by a lock nut (124); removal of the lock nut enables the shaft to be withdrawn from the housing.

A flange 22 on the sleeve carries pivoted arms 25 provided with rollers 27 which are pressed by springs 28 into contact with the rim. 24 of the disc, and flats 23 on the flange. The arms are rocked to release the coupling by means of a knob 37 secured to a rod 31 having a finger 32 which passes through flared openings 10 in the shaft 9 and sleeve 11 and engages a rocking piece 29 formed with fingers 34 and shoulders 36 engaging the arms. The knob is revoluble on a sleeve 14 secured to the sleeve 11 and is resiliently connected thereto by means of a spring band 40, Fig. 1, having at the ends pairs of lugs 41, 42 engaging the sides of slots 43, 44 formed in a flange 38 on the knob, and the sleeve 14 respectively. On turning the knob in either direction, the coupling is released by means of the rocking piece 29, and the platen is then caused to rotate by the engagement of the finger 32 with the walls of the openings 10 and by the engagement of the pairs of lugs 41, 42. In a modification, the rocking piece operated by the finger 32 engages two levers each operating a pair of the arms 25. In another modification, shown in Fig. 6, the edges 23 of the flange 22 are formed as circular arcs and the rocking piece 53 operated by the finger 32 co-operates with the ends 50 of pivoted arms 49 carrying the rollers 27. On rocking the piece 52 in either direction, diagonally opposite arms are rocked to release the rollers thereon, and the other rollers are drawn out of coupling position by the rotation of the flange.
Patent GB-901038-A (GB)
Title: Improvements relating to graft copolymer shaped structures
IPC: D06M14/34
Filed: 1958-10-30
Abstract: Graft copolymers are prepared in which the base polymer is a linear nitrogenous condensation polymer and the grafted units are linear chains free from aliphatic unsaturation which carry amide groups and are linked to the condensation polymer by carbon-carbon bonds. Condensation polymers specified are polyamides, e.g. polyhexamethylene adipamide and polycaproamide, polyurethanes, polyureas, poly(ether-urethanes) and polysulphonamides.  The grafted side chains are produced by the polymerization of unsaturated amides in the presence of the condensation polymer, suitable amides being acrylamide, methacrylamide, ethacrylamide, N-methylol acrylamide, N-methyl-N-vinyl formamide, N-vinylpyrrolidone, N-vinyl-valerolactam and N-vinylcaprolactam.  Mixtures of such amides with one another or with other monomers may be used.  The grafting is preferably applied to the condensation polymer in shaped form, e.g. fibre or film, although other forms, e.g. flake, powder or melt, may be employed. The amide monomer may be used as such or in the form of an aqueous solution, polymerization being induced thermally, by the use of free-radical catalysts or by the use of ultra-violet light in conjunction with a photo-initiator, if desired.  The process is used to confer desirable properties on the condensation polymer substrates; in particular, fabrics made from grafted nylon exhibit dyeability and may be subjected to a hydrosetting treatment whereby a permanent configuration is achieved.  The Specification describes also the preparation of a poly(ether-urethane) by reacting poly(tetramethylene oxide) glycol with 4-methyl-m-phenylene diisocyanate to produce a dimer with hydroxyl ends, which is added to methylene bis(4-phenyl-isocyanate) dissolved in methylene chloride. To the isocyanate terminated dimer so formed are added dimethyl formamide and hydrazine hydrate and polymer is precipitated from the resulting solution by adding it to glycerol.  Specifications 461,236, 535,139, 724,759, 838,412, 868,651 and 901,039 are referred to.
