Title: Improvements in or relating to hydraulic jet propulsion apparatus for water-borne craft
IPC: B63H11/11
Filed: 1960-03-22
Abstract: 919,216. Hydraulic jet propulsion. HAMILTON & CO. Ltd., C. W. F. March 22, 1960 [March 24, 1959], No. 10080/60. Class 114. A hydraulic jet propulsion apparatus for water-borne craft comprises an intake section 1 having a screen 3 of tapered bars 3a, 3b across the intake opening, a roto-dynamic pump 4 detachably secured to the intake section, a discharge section 28 detachably secured to the pump, drive transmission means 9 whereby power can be transmitted to operate the pump, and control means associated with the discharge section whereby the direction of the propulsive jet of water discharged from the pump can be controlled so as to propel the craft in a desired direction. The pump comprises impellers 12, 13 and guide vanes 14 in a casing 15. The discharge section includes a straightening vane assembly 29 and a replaceable nozzle 30 having a bore skew to the axis of the outer surface of the nozzle so that by rotating the nozzle 30 in the tail pipe 28 so as to vary the angular disposition of the nozzle, fine connections may be made to the steering trim of the craft. 33 is an off-take for an auxiliary water service pipe 34. Control means arranged rearwardly of the outlet-of the tail pipe 28 consist of a gate 37 for stopping and reversing the craft and a pair of deflectors 38 for steering. In its raised position the gate 37 offers no impediment to the free discharge of water from the pump 4 producing forward propulsion of the craft. When lowered to the position shown in Fig. 2, the gate 37 closes the outlet opening of pipe 28. By lowering the gate still further the outlet opening of pipe 28 is again opened for discharge of water therefrom but the direction of discharge is reversed by means of a recess 37b in the gate so that a reverse motion is imparted to the craft. The deflectors 38 are hinged on the cover 39 of the gate housing and are connected by arms 44 to a control shaft 45 by rotation of which the angular setting of the deflectors can be altered so as to alter the angle of discharge of the jet of water issuing from the tail pipe 28 and thereby change the direction of travel of the craft.

Title: Wheat flour classification
IPC: A23L7/10
Filed: 1964-03-11
Abstract: 1,020,208. Aggregating, classifying and upgrading wheat flour. CARNATION CO. March 11, 1964 [March 23, 1963], No. 10238/64. Headings A2E and A2Q. In aggregating and classifying wheat flour, e.g. winter wheat flour, to obtain fractions in which the protein and ash contents, computed as percentages by weight, generally increase with increasing size of the aggregates, the flour is moistened, e.g. sprayed with water and steam, as it falls through an ascending current of air, so that its particles mingle and stick together to form random-shaped, moist aggregates, which are then dried, e.g. to attain a moisture content of 14% by weight, and separated into fractions, as by sifting. Some or substantially all of the aggregates may be reduced in size between rolls. In upgrading wheat flour according to the invention, the small aggregates are removed leaving coarser aggregates having higher protein and ash contents than the original flour.

Title: Improvements in mechanism for transmitting data
IPC: H04L15/18
Filed: 1930-04-01
Abstract: 354,745. Rack-and-pinion gearing. STACEY, C. F., War Office, London. April 1, 1930, No. 10370. [Class 80 (i).] Mechanism for transmitting data representing a quantity varying at a changing rate according to some function of the movement of a member, or for operating in the manner of a cam, comprises a strip of material provided along its length with apertures or equivalent means, the spacing of which is varied in progressive increments according to the function or cam movement being dealt with. In the construction shown in Figs. 6 and 8, the toothed segment 1 engages a worm 2 fixed to a shaft 10 which leads to a differential gear within a casing 8. The casing is rigid with a commutator 9 and a gear wheel 7, the latter meshing with a gear wheel 6 mounted on a shaft 4 driven by a hand-wheel 3. The shaft 4 also carries a toothed roller 5 which is adapted to drive, through the medium of a perforated steel tape, a sprocket 12 on the shaft 11 of the differential gear. The tape, as shown in Fig. 8, is provided with three rows of'perforations, the outer rows for engagement with the teeth on the sprocket wheel 12, and the inner row for engagement with the teeth on the roller 5. The teeth 14, 15 of the sprocket wheel 12 are formed so that they retain meshing engagement with the holes in the tape when the spacing between these holes is varied to a limited extent (either by expansion or contraction) from the normal spacing. The gear ratio of the wheels 6, 7 is such that when a portion of the tape such as shown in the left portion of Fig. 8 is fed between the roller 5 and the wheel 12, the shaft 11 rotates at twice the speed of the casing 8, and consequently no movement of the shaft 10 takes place. If a portion of tape such as shown in the right portion of Fig. 8 is engaged, the movement of the shaft 11 relatively to the movement of the shaft 4 is increased and therefore in this case a movement of the shaft 10 does take place. The effect of the tape is therefore to act as a cam. Assuming that it is desired to move segment 1 to a new setting the hand-wheel 3 is rotated until the new setting is obtained and during this movement impulses are transmitted over lines 13a which act to record a function of the angular movement of the segment 1. Markings are made on the tape to indicate resultant settings of the segment 1.

Title: Recovery of amines
Inventor: HORN IRVIN BRUCE VAN
Filed: 1965-03-11
Abstract: Aromatic primary mono- and di-amines are prepared by heating water and the distillation residue obtained from the product of phosgenation of an aromatic mono- or di-amine, after distilling off the corresponding aromatic isocyanate, to a temperature above 250 DEG C. but not above 350 DEG  C.  If desired, the water may contain up to 10% by weight of an alkali metal hydroxide.  Preferably the reaction mixture is maintained under a pressure of at least 100 p.s.i.g. but not exceeding 2500 p.s.i.g.  The process is particularly suitable for the preparation of 2,4- and 2,6-toluylene diamines by treatment of the distillation residue obtained by the phosgenation of a mixture of 2,4- and 2,6-toluylene diamine after distilling off the diisocyanates. It is also useful, for example, in the treatment of the distillation residues obtained in the production of phenyl isocyanate, diphenyl-methane diisocyanates such as 4,41-diphenyl-methane-diisocyanate, and naphthalene diisocyanates.

Title: Improvements in mechanism for applying elastic gaskets to cans and like containers
IPC: B21D51/46
Filed: 1932-04-12
Abstract: 385,501. Applying elastic gaskets to cans &c. CONTINENTAL CAN CO., Inc., 100, East 42nd Street, New York, U.S.A.- (Assignees of Aulbach, C. J. ; 1016, East Water Street, Syracuse, New York, U.S.A.) April 12, 1932, No. 10439. Convention date, Oct. 16, 1931. [Class 125 (iii).] A mechanism for applying elastic gaskets to cans &c. comprises means for receiving and expanding a pre-formed gasket, which operate to place the gasket in a predetermined position on a can &c., the gasket being stripped from the expanding means after being positioned in contact with the can &c. A can &c. 1, in an inverted position, is placed with its rim in a recess 27 formed in a table 18 which may be raised by the manual operation of a lever, the table being prevented from rotation by a feather 17. A preformed elastic gasket 10 had previously been placed to encircle four pins 32, 36, 39, 42, carried by pivoted arms 28 .. 31, each pin being at its inner position in a corresponding arcuate slot 34, 37, 40, 43 cut in the table 18, the pins being then moved radially by a treadle-actuated lever system through a spur wheel 48 engaging with a segment gear carried by each arm. The elastic gasket, which is preferably of rectangular section, is therefore stretched and the container top is then inserted within it. The treadle is then released so that the pins close inwardly to contact with the side of the container and in this position, due to the dimensions of the pins, the gasket between the pins contacts with the container wall. The table 18 is then moved upwardly, stripping the gasket from the pins which springs into its correct predetermined position. The lid 5 of the can &c. is now placed in position and the closure sealed by a metallic ring 8 turned upwardly at its lower edge to compress the packing gasket 10, Fig. 9.

A derivative of a water-dispersable polysaccharide contains both anionic and cationic groups which are capable of ionization in an aqueous medium and which are respectively attached at separate places on the polysaccharide chain, the nature of and the ratio between which give the derivative an isoelectric point in the pH range 2-10À5. Conventional etherification or esterification is used to introduce these charged groups separately, in either order, or both types simultaneously. The cationic group may be primary, secondary or tertiary amino; quaternary ammonium; sulphonium or phosphonium, and such groups are introduced, e.g. by etherification with appropriate epoxy- or chloro-compounds. The anionic group may be carboxyl, sulphonate, sulphate or phosphate, and may be introduced as follows:-Carboxyl by reaction with (a) monohalogen fatty acids, (b) anhydrides, e.g. of maleic, succinic or citraconic acids, (c) Me and Et esters of acrylic, crotonic or itaconic acids, (d) acrylonitrile followed by hydrolysis of the CN groups or (e) Na periodate followed by NaClO 2  to convert the C=O groups to COOH. Sulphate by reaction with tertiary amine/SO 2  adducts or by sulphamic acid and/or sulphuric acid-urea treatment. Sulphonate by reaction with (a) sultones, (b) the Na salt of haloalkane sulphonic acids, oxypropane or epoxypropane sulphonic acid, or ethylene sulphonic acid or (c) Na periodate followed by treatment with a bisulphite. Phosphate by treatment with phosphates, phosphoric or polyphosphoric acids. Carboxy and sulphonate groups together by reaction with an unsaturated acid anhydride followed by a bisulphite treatment. Specified polysaccharides are starch, including high amylose starch and plant gums and mucilages, e.g. carob, guar and tamerind seed gums. In examples the following combinations of groups feature: diethylaminoethyl with sulphate, sulphopropyl or carboxymethyl, and triethylammoniumhydroxypropyl with sulphoethyl or phosphate.
