Title: Dry preparations capable of yielding cation-active melamine resin solutions by dissolution in water and ripening and process for their manufacture
IPC: C08G12/32
Filed: 1956-11-21
Abstract: Dry preparations capable of yielding cation-active melamine resins solutions by dissolution in water and ripening consist of a hardenable condensate of 1 mol. of melamine with 2-6 mols. formaldehyde in which there are bound 0.5-1.5 mols. of a strong monobasic mineral acid, and may be prepared by spray drying aqueous solutions of the condensates and, if desired, subjecting the so-formed powders to further drying with powerful dehydrating agents, e.g. P2O5 or H2SO4.  Preferably th condensate is prepared in alkaline solution and the acid then added, or the acid may be added to a solution of a dried condensate, and the mixture cautiously dried. Ripening is shortened by raising the temperature.  The acid content can be lowered to the desired value by blending the acidified resin with melamine-formaldehyde condensate not containing acid.  Acids used in specific examples are hydrochloric and nitric.  The products are useful in the textile finishing and paper-making industries. Specification 623,355 is referred to.

[Also in Division C7] A semi-conductive layer of single crystalline Si is deposited on a monocrystalline Al 2 O 3  substrate by heating the substrate to about 1150‹ C. in a silane containing atmosphere and then heating the coated substrate in a non- reactive atmosphere, e.g. hydrogen, to a temperature of at least 1250‹ C. but below the melting point of the Si, preferably 1335- 1400‹ C. The 22#43 crystal face of an Al 2 O 3  disc is preferably coated and the disc is heated in a furnace 11 on a Si susceptor 34 to 1250‹ C. in H 2  after first flushing with He. The substrate is then cooled and maintained at about 1150‹ C. while a. mixture of silane and H 2  is passed through the furnace to deposit an Si coating 1-50 microns thick. The coated substrate is then heated in H 2  or an inert gas at 1335-1400‹ C.

[Class 38 (ii).] Thermionic valves 1, 2, 3 in a generating or amplifying circuit have output circuits which include a combination of resistance 4, 6 and capacity 5, 7 or a combination of resistance and inductance (not shown), which brings about a phase displacement of 180‹ in the desired frequency, and reaction, which is strongly negative for the other frequencies, prevents amplification of those frequencies. As shown, three valves are used with reaction taken by a conductor 8 from the output of the last valve 3 to the input to the first valve 1. The reaction is regulated by a variable tapping 17 or by varying the grid bias of one or more valves. Screened-grid valves are used to neutralize the influence of anode-grid capacity. The condensers or the resistances are varied to regulate the frequency amplified. A single valve may be employed, Fig. 3 (not shown).

Abstract: 744,119. Aerials. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Dec. 21, 1954 [Dec. 30, 1953], No. 36226/53. Class 40 (7). A counterpoise earth arrangement for use with an unbalanced aerial feeder system consists of a conductive loop 4 surrounding the feeder and a single substantially straight conductive member 6 connecting the loop to the side of the feeder 3 not connected to the aerial. In the embodiment shown the transmission line feeder is a coaxial one and has its inner conductor 2 connected to the unipole aerial 1 and the counterpoise attached to its outer conductor. The configuration of the loop is preferably circular, the circle being in a plane at right angles to the transmission line. The circumference of the loop 4 plus the length of member 6 is made half a wavelength at the mid-frequency of operation. The transmission line impedance may be matched to that of the aerial by adjusting the point of attachment of the member 6 to the outer conductor 5. If necessary the conductor 5 may be extended by a single wire conductor arranged parallel to the aerial 1 and the member 6 attached thereto. The loop may be distorted out of the circular and need not exactly lie in a plane at right angles to the aerial axis. If the length of the aerial differs from a quarter wavelength the total counterpoise length as specified above should be arranged to be twice the aerial length.

Abstract: 621,917. Refrigerators. AKTIESELSKAPET DRAMMENS JERNSTOBERI & MEK. VAERKSTED, and THARALDSEN, T. W. Dec. 16, 1946, No. 37067. Convention date, Nov. 28, 1945. [Class 29] [Also in Group XXX] In apparatus of the type in which the goods are frozen in heat conductive containers 1 conveyed through the apparatus with their side walls in sliding contact with spaced plane refrigerating surfaces 2, the conveying means 3, 8 is adapted at increasing resistance against the sliding movement automatically to cause a displacement of the containers perpendicular to their direction of movement. The containers 1 are moved intermittently through the chamber by an endless chain conveyer 3 and are of wedge shape, with the smaller ends directed downwardly during the freezing process. The evaporator surfaces 2 are also wedge shaped to correspond'with the containers so that the weight of the containers and the goods, which are fed to the containers through a door 13, causes intimate contact between the heat transfer surfaces. Each container has a bottom flange 10 connected by a pair of parallel links 8 with the conveyer chain 3, one link 8 being acted on by a spring 12 to maintain the containers in a raised position before they enter between the evaporators and are loaded. The conveyer moves in the direction of the arrow and excessive resistance to movement of the containers causes the links 8 to raise them and so relieve the resistance. After passing between the evaporators, the containers pass to a temperature equalising space and then between heating plates 6, similar to the evaporator plates, for loosening of the frozen goods, which are removed through a door 7. The empty containers pass over pre-cooling pipes 22 or past an air cooler 21 with fan 20 before being re-loaded. The heating portion 6 is insulated from the casing. Certain containers carry scrapers 19 to remove rime. Stops 14 on the conveyer ensure the correct angle of the links 8 on the lower run of the conveyer. The side walls of the container are hinged at 16 and the end walls 17, 18 comprise overlapping flanges or flexible members to allow intimate contact with the evaporators. The refrigerating surfaces 2 may be resiliently mounted. The Specification as open to inspection under Sect. 91 states that the distance between the evaporator surfaces may increase slightly in the direction of movement of the conveyer to allow for the expansion of the goods in freezing, and they may be slightly moved in the same direction as the goods. This subjectmatter does not appear in the Specification as accepted.
