Abstract: 954,475. Sheet receivers. EASTMAN KODAK CO. March 26, 1963 [March 26, 1962], No. 11992/63. Heading B6H. An adjustable stop mechanism for a storage compartment or sheet receiver having a base 10 and spaced side walls 12, 14, 28 and 29 comprises two rotatable plates 16, 17 extending longitudinally of the compartment and supported by the opposite walls 12 and 14. Each plate has sheet stops 24, 26 (25, 27) in the form of lips extending transversely from opposite faces thereof and spaced axially therealong. A selector mechanism is provided for rotatably moving the plates 16, 17 between three different positions; a first position, Figs. 2 and 3 (not shown), in which the plates are normal to the base 10 and stops 26, 27 co-operate to form a stop for a stack of sheets of one length, a second position in which the plates are parallel to the base 10 and both sets of stops are withdrawn from the compartment into an inoperative position, Figs. 4 and 5 (not shown), and a third position, Figs. 6 and 7 (not shown), in which the plates are normal to the base 10 and stops 24, 25 co-operate to form a stop for a stack of sheets of a different length. The selector mechanism includes a crank lever 38 and a detent mechanism for maintaining the plates in the three positions. A single plate 16 or 17 may be provided instead of two, and the mechanism may also be modified by incorporating another plate on the shaft 18, 19 of each plate angularly spaced 90 degrees from the present plate. The added plate would be provided with stops in different positions from the present plates providing stops for sheets of different lengths.

Abstract: 719,544. Hydraulic couplings. VOITH GES., J. M. May 23, 1951 [Oct. 1, 1948], No. 12083/51, Class 69 (2)  A power transmission system comprises an electric motor having a short circuited rotor driving a hydraulic coupling comprising a container connected to the impeller and adapted to take up part of the working fluid when the coupling is stationary and connected by passages at its part of largest diameter with the space within the impeller so that on starting the container discharges gradually into the working circuit. An impeller 3 is connected to a shaft 1 driven by the motor and forms with a flange 2 and a wall 8 connected thereto a chamber 9 in which fluid collects to the level 12 when the coupling is stationary; the chamber 9 is connected to the working space by ducts 10 and by narrow air ducts .11 to allow air to be expelled.. The Specification describes two modifications in which the internal diameter of the impeller blading is greater than that of the runner whereby an accumulator space is provided between the impeller and the runner. In one case the air duct is formed in the wall forming the chamber and communicates with the working space at the inlet edge of the impeller and in the other a similar duct is formed between the said wall and part of the casing forming the accumulator space. The runner may have a greater internal diameter than the impeller.

Abstract: 438,570. Cooking-vessels. WILCOX, H., 1176, Ossington Avenue, Toronto, Canada. April 23, 1935, No. 12172. [Class 66] [See also Group XI] A cooking-utensil 11 comprises an outer shell and a closely fitting lining of a different coefficient of thermal expansion and an indentation 14 is formed in its bottom. When the temperature of the bottom of the utensil becomes excessive the different thermal expansions of the two shells cause the indentations to spring apart and leave a heat insulating air space. In an alternative construction internesting annular grooves are formed in the bottom of the shells which spring apart and leave an air space in a similar manner to the previous construction. A heat storing and distributing plate may fit between the two shells at the bottom.

Title: Improvements in polymer compositions and in the production of shaped articles
IPC: D01F6/74
Filed: 1945-05-16
Abstract: Polymer compositions comprise a poly-1.2.4-triazole (see Specifications 612,609 and 613,020) and as solvent an alcoholic compound.  The alcoholic compound may be a glycol or other polyhydric alcohol, a chlorinated alcohol, a nitro alcohol, or an aromatic alcohol, or it may be an unsubstituted aliphatic alcohol of not more than eight carbon atoms alone or used in admixture with a polar chlorinated hydrocarbon, an aromatic hydrocarbon of the benzene series, or a nitro-aliphatic hydrocarbon.  Monohydric alcohols such as methanol, ethanol, the propanols, and butanols, are solvents for poly-1.2.4-triazoles melting below 245 DEG  C., but require to be mixed as above to dissolve higher-melting polymers, e.g. with chloroform, methylene chloride, benzene, toluene or nitromethane. Solvents specified are 1.1.1-trichlor-2-methyl-2-propanol, 1.1.1-trichlor-2-propanol, ethylene and glycerine chlorhydrins, benzyl alcohol, 1-nitro-2-propanol, 2-nitro-1-propanol, 2-nitro-1-butanol, 1-nitro-2-butanol, and 3-nitro-2-butanol, glycols such as ethylene, propylene, di- and tri-ethylene, 1.4-butylene, and 1.6-hexylene glycols, glycerine and similar polyhydric alcohols. The compositions may be used as lacquers or coating compositions together with plasticizers, resins, colouring matters and pigments, or may be formed into filaments or films by dry or wet methods.  In examples: (1) a polymer obtained from sebacic diamide and dihydrazide according to examples (1) and (2) of Specification 613,020 is refluxed with methanol, and the solution so obtained is spread on a film-forming surface; a polymer formed from sebacic dihydrazide is refluxed with (2) 4 parts methanol and 1 part chloroform; (3) 3-chloro-1-propanol; (4) ethylene glycol, the products of (2) and (3) being formed into films, and that of (4) being melt-spun into filaments. Poly-1.2.4-triazoles melting below 245 DEG  C. may be obtained from higher melting poly-1.2.4-triazoles by heat-treatment in absence of steam or hydrazine hydrate, or treatment with cold nitrous acid followed by alkali.

Abstract: Substituted pteridines having in one tautomeric form the general formula <FORM:0655771/IV (b)/1> wherein R is a substituted amino group, are prepared by admixing: (i) 2,4,5-triamino-6-hydroxypyrimidine, a tautomer thereof or a salt thereof; (ii) an amide of para-aminobenzoic acid or a salt or ester of an amino acid amide thereof; (iii) a compound of the formula <FORM:0655771/IV (b)/2> wherein X is hydrogen or halogen at least one being halogen and R1 is an acyl radical.  The reaction may be carried out at a temperature in the range of about 0 DEG  to 60 DEG  C., and/or within a pH range of about 1 to 5.  Reactant (iii) may be a substituted acetoxy, propionoxy or butyroxy acetone, e.g. 1,1-dichloro-, 1,3-dichloro-, 1,1-dibromo-, 1,3-dibromo-, 1-chloro-1-bromo-and 1-bromo-3-chloro-3-acetoxyacetone.  The amino acid amide may be derived from glutamic or aspartic acid, glycine, alanine, isovaline or cysteine.  In the example, pteroylglutamic acid is prepared by brominating 1-chloro-3-acetoxyacetone with bromine in glacial acetic acid in the presence of ultra-violet lamp radiation, and the brominated product is reacted with 2,4,5-triamino - 6 - hydroxypyrimidine sulphate and para-aminobenzoyl-glutamic acid.

Abstract: 528,023. Multiplex transmission. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., PARKER, J. E. T., and McCUSKER, J. B. April 26, 1939, No. 12529. [Class 40(iv)] In a system having a carrier frequency channel and an audio-frequency channel superimposed on the same line, signalling for one channel is effected by direct current while that for the other channel is. effected by alternating curent. As shown, the channels are separated by high- and low-pass filters HPF, LPF3 and are connected to the exchange equipment over lines 10, 11 and 12, 13, the terminal apparatus for the carrier channel including a balanced modulatordemodulator MD fed by an oscillator OSC. Ringing over the audio channel is effected by low-frequency A.C. which passes directly to the line. Ringing current over the line 10, 11 operates relay R which connects positive battery through rectifiers MRL, MRM and the windings of relay M to both wires of the line 14, 15. The windings of M are normally connected to negative battery through rectifiers MRV, MRK, so that it responds to the D.C. signal and through relay C applies ringing current to the line 10, 11. The arrangement of rectifiers guards against possible operation of M by ringing current. The frequency of the oscillator OSC may be adjusted by means of a variable condenser QD, and the synchronism of the oscillators at the two ends of the line 10, 11 may be tested by plugging a telephone instrument in a jack JL, a beat frequency being heard if lack of synchronism exists.
