Title: Improved process and apparatus for malting grain
IPC: C12C1/00
Filed: 1932-12-07
Abstract: 411,181. Malting - apparatus. KUSSEROW, R. E., 686, Jean Street, Oakland, California, U.S.A. Dec. 7, 1932, No. 34736. [Class 14 (ii).] A process of malting without transfer of grain comprises soaking grain in liquid for repeated comparatively short periods, draining the liquid therefrom after each soaking, and germinating the grain in the presence of a continuous stream of air passed therethrough. The process may be carried out in a tank 10 provided with a floor 17 pervious to water and air, but capable of supporting a bed of grain thereon. The floor 17 is spaced away from the bottom 11 of the tank 10, and means for introducing air into the tank below the level of the floor is provided consisting of perforated pipes 28 supplied with compressed air from a reservoir 35 by way of a pipe 43 and branched pipes 34 closable by valves 31. Means are also provided for evacuating air from the apparatus, comprising a vacuum pump 41 connected to the pipe 34 by way of a pipe 48 having a valve 42 thereon, a valve 44 on the compressed air supply pipe 43 being closed when the vacuum is to be applied. Water is supplied to the tank from a reservoir 36 by way of pipes 33 and 25, a valve 27 being provided on the pipe 33. Another branch 32 of the pipe 25, closable by a valve 26, is provided for emptying the water from the tank. A shoot 14 having a closure member 15 controlled by a clamp screw 23 and hand wheel 24 enables the grain to be discharged after treatment. Additional means for quickly draining carbon dioxide from the tank consist of a pipe 37 depending from the bottom 11 thereof, and having a hinged closure 38 locked by means of a quick-acting clamp 40. In operation, the grain is spread on the floor 17 as shown at 45, and the tank is filled with water to the level 46. Alkali or acid, such as lime, sodium carbonate sodium silicate, hydrochloric acid, or other chemicals may be added to the water to remove or weaken deleterious micro-organisms. Air is passed through the grain while it is thus allowed to soak during a period of ten minutes to two hours, the water is then allowed to drain away, and the operation is repeated at intervals over twelve to forty-eight hours, after which the tank is filled with water to the level 47, and moistened air is passed through the grain over a period up to twelve days in order to maintain the correct germination temperature. At intervals during this latter process the water may be emptied from the tank and the direction of the flow of air reversed.

Title: Improvements in push button tuning mechanism for radio receivers
IPC: H03J5/12
Filed: 1946-11-22
Abstract: 625,068. Push-button tuning mechanism. HANSEN, H. C. Nov. 22, 1946, No. 34742. Convention date, Dec. 10, 1945. [Class 40 (v)] In a, push-button tuning mechanism, as shown, each button 2 is attached to a lever 3 mounted on a common spindle 4 and connected by a helical spring 5 to a second lever 7, 8, carried on a common spindle 6 parallel to the spindle 4, the spring being kept in tension by means of a member 19 between the two levers and attached to the lever 3. The lever 8 bears on the moving plates 10 of the tuning condenser which are attached to a cord driving the rotatable scale 17, the other endof the cord being connected to a helical spring 16 fixed to the frame. On depression of the push-button 2 the lever 8 moves the condenser plates 10 into the required position which is determined by the adjustable stop 22 on the end of the screw 23 mounted in the frame, the lever 3 continuing its motion to cause the member 19 to engage with a common locking bar 27 and also release any other button which may be depressed. The condenser may be inserted and fixed in the frame as a unit independent of the operating mechanism and without affecting the adjustments. For continuous tuning, Fig. 2 (not shown), the appropriate button is pressed and a similar mechanism, but without the adjustable stop portion, moves an arm into contact with a cam which may be rotated by means not shown to move the condenser into any desired position.
Patent GB-1016380-A (GB)
Title: Epoxy-polyamides
Inventor: BARRETT ROBERT MCDOWELL
IPC: C08J7/04
Filed: 1963-09-03
Abstract: A cationic thermosetting resin is produced in three stages: (a) itaconic acid is reacted with an alkylene or arylene diamine; (b) the heterocyclic dibasic acid so produces is reacted with a polyalkylene polyamine and (c) the water-soluble polyamide so produced is reacted with epichclorohydrin.  The alkylene or arylene diamine may be ethylene or phenylene diamine, the former giving an acid of structure <FORM:1016380/C3/1> The diamine may be used in 5% excess over the itaconic acid.  In stage (b) polylkylene polyamines specified are: diethylene triamine, triethylene tetramine, tetraethylene pentamine, pentaethylene hexamine and mixtures thereof.  The reaction may be at 110-250 DEG  C. atmospheric pressure and the ratio of the reactants such that the primary but not the secondary amino groups are interacted.  An alkylene diamine, e.g. ethylene diamine, may also be present.  Stage (c) may be at 45-00 DEG  C., sufficient epichlorohydrin being used to make all the secondary amine groups tertiary. The product may be diluted with water to 20-30% solids and acidified to a pH below 4. The tertiary amine groups may be quarternized by adding alkyl halides, sulphates or phosphates or substituted alkyl halides.  The product may be used to improve the bonding of moisture-proof coatings on non-fibrous, regenerated cellulose film and to produce "wet-strength" in paper.  Once absorbed on the paper the resin may be cured under acid neutral or alkaline conditions at elevated temperature.ALSO:A paper having wet-strength is produced by adding a novel epoxy-resin to the paper pulp.  The epoxy-resin is produced by (a) reacting itaconic acid with an alkylene or arylene diamine, e.g. ethylene or phenylene dramine, (b) reacting the heterocyclic dicarboxylic acid so formed with a polyalkylene polyamine, e.g. diethylene triamine, triethylene tetra-amine, tetraethylene penta-amine or pentaethylene hexamine, and (c) treating the water-soluble polyamide so formed with epichlorohydrin.  It may be further treated with an alkyl halide, sulphate, e.g. dimethyl sulphate, or phosphate to quaterize the intnogen atoms.  2.5% of the epoxy-resins prepared in the examples are mixed with paper pulp, and the pH adjusted to 7.5 by adding Na2CO3. The pulp was then made into paper.

Title: Improvements in and relating to fuel pumps for internal combustion turbines
IPC: F02C9/16
Filed: 1931-12-21
Abstract: 381,029. Turbines. HOLZWARTH, H., 7, Goethestrasse, D³sseldorf, Germany. Dec. 21, 1931, No. 35296. Convention date, Dec. 19, 1930. [Class 110 (iii).] The fuel pump for an internal-combustion turbine is controlled so that the effective beginning of the delivery of fuel is varied in accordance with the frequency or number of cycles of the explosion chamber. The internalcombustion turbine 34 is associated with the electric generator 35, the steam turbine 36 which is supplied with steam produced by waste heat of the combustion turbine 34, and the compressor 37 for the charging air supplied to the combustion turbine through the pipe 38. A relief valve consisting of a spring-pressed piston 58 is connected by the pipe 79 to the pipe 38. A fuel supply regulator 39 makes a rotary movement due to the motor 44 and worm gear 43, and an axial movement due to the movement of the piston 49 when pressure fluid is supplied to the cylinder 51. A fuel pipe 56 leads from the regulator to the pump member controlling the delivery to the turbine 34 by the pipe 57. As the load on the generator 35 falls the speed of revolution rises. The speed governor 54 actuates the slide valve 52 thereby causing the operation of the piston 49. The controlling body 45 of the regulator is moved axially to a position corresponding to the altered number of cycles, and at the same time the revolutions of the controlling shaft are regulated by the alteration in the position of the controller 55. The impulses of the fuel supplied to the pump members supplying the combustion chambers are therefore altered so that the effective beginning of the delivery of fuel is displaced to the instant suitable to the actual number of cycles. The pressure of the charging air is also varied, owing to the altered speed of the compressor 37. Constructional details of apparatus for the hydraulic actuation of the pump plunger controlling the effective beginning of the delivery of fuel, are given.
