Title: Improvements in the production of amphoteric finishing agents from carboxylic acids and hydroxyalkyl amines which agents are stable to high temperatures and the hardnessin water
IPC: D06M15/423
Filed: 1956-01-17
Abstract: Softening agents for fibres and fabrics are made by reacting together (a) a condensation product of at least one higher fatty acid with at least one trihydroxyalkyl-dialkylene-triamine, such product containing amide and/or ester groups, and (b) at least one aliphatic or aromatic dicarboxylic acid, the final product containing a free carboxylic group.  Examples show the condensation of N : N1 : N11-tri-(hydroxyethyl)-diethylene-triamine with stearic acid and then with maleic or succinic acid.  Other specified reactants are trihydroxypropyl dialkylene diamines, lauric acid, coconut acid, oleic acid linolenic acid, acids from tallow and palm oil, adipic acid and phthalic acid.  The compounds may be applied in aqueous solution in the form of their caustic soda or mono- or tri-ethanolamine salts to wool, cotton, spun rayon, acetate rayon, polyamide, polyacrylonitrile and polyester fibres.  They can be used together with urea - formaldehyde, melamine - formaldehyde and polyacrylic ester resins.ALSO:Textile finishing agents are made by reacting together (a) a condensation product of at least one higher fatty acid with at least one trihydroxyalkyl - dialkylene - triamine, such product containing amide and/or ester groups; and (b) at least one aliphatic or aromatic dicarboxylic acid; the time and proportions are chosen so that the final product contains some unreacted carboxylic groups, preferably half of those in the dicarboxylic acid. Examples show the condensation of N : N1 : N11-tri-(hydroxyethyl) - diethylene - triamine with stearic acid (1 or 2 mols.) and then with maleic or succinic acid.  Other specified reactants are trihydroxypropyldialkylene diamine; lauric acid, coconut acid, oleic acid, linoleic acid and acids from tallow and palm oil; adipic and phthalic acids.  Reactant (a) may be one of those described in Specification 680,688.  The products form salts with caustic soda and organic bases such as mono- and tri-ethanolamines.
Patent GB-742399-A (GB)
Title: Improved method of treating tough cast iron and castings obtained thereby
Filed: 1953-01-19
Abstract: A process for the treatment of white cast iron comprises austenisation at a temperature slightly above that at the end of the eutectoid transformation, step-quenching to produce martensite without shrinkage cracks, reheating to a temperature in the range 430-530 DEG C., depending on the composition of the metal to produce nuclei of graphite, and graphitisation at a temperature above that of the eutectoid transformation followed by cooling in still air. The step-quenching may comprise quenching in a salt bath at a temperature above that of martensite formation for a time less than that which produces transformation to bainite followed by cooling in still air. A sand casting may be heated at 810 DEG C., quenched in a salt bath at 180 DEG C. for 1 minute and cooled in still air, reheated at 450 DEG C. for 48 hours, cooled, and finally reheated to 895 DEG C. for 14 hours and cooled in still air.  For chill castings the graphitising may be at 875 DEG C. for three hours.

Abstract: 873,027. Frequency discriminators. EPSCO Inc. Jan. 16, 1958 [Jan. 17, 1957], No. 1626/58. Class 40(5) Set and re-set trains of pulses S, R, are derived one from the other by a constant delay means and applied to a bi-stable circuit 15 to derive pulses of variable duration dependent on the pulse repetition frequency of the original pulse train, and of oppositely polarity which are applied to open a current switch or gate valve 72 supplied with constant current from a series valve 25, a portion of which passes through an impedance Zp. A continuous constant current also passes through an impedance Zs from a valve 26 and a differential amplifier 77 amplifies a voltage dependent on the current difference, and may have negative feedback from its output through an impedance Zf to the pulsed voltage across impedance Zp, the output voltage being zero at a predetermined p.r.f. variable by adjusting the impedance Zs, and of opposite polarity for frequency variations on either side of this value. A squelch system rendering the circuit inoperative when the amplitude of the pulses falls below a predetermined level comprises gate valves 27, 28 coupled as shown to the current source valves 25, 26 to open the latter only when a Schmitt trigger circuit 36 (producing a n egative output voltage) is operated by a sufficient amplitude of input at 35. The original pulse train may be derived from a frequency modulated wave by squaring, limiting, differentiating, and blocking oscillator sharpening circuits. The delay device may be a network, or valve circuit, or quartz delay line and preferably produces a delay greater than one half the mean period of the input signal, or slightly less than a multiple of the mean period.

Abstract: 574,302. Photographic developing apparatus. HIGHAM, L. G. Jan. 29, 1944, No. 1701. [Class 98 (ii)] Apparatus for the development of photographic prints by means of a gas such as ammonia comprises a rotatable carrier mounted in a casing, the carrier having five compartments which, on rotation, connect successively with the front opening, the development chamber, an opening for discharging the gas, and finally with an inclined wall down which the developed print is delivered. The carrier shown is divided longitudinally by radial partitions 15, 16, 17, 18 and 19 which form with the end walls 11, five sector-shaped troughs. On the outer edge of each partition is a felt, rubber or other flexible lip 20 adapted to make a gas-tight seal with abutments on the casing. The space between the end walls of the carrier and the casing is also backed with felt. The casing is rotated step-by-step by means of a five-toothed ratchet wheel 26 actuated by a pawl 27 mounted on a quadrantal lever 28. The development space 30 contains an electric heater 35 and a trough 34 into which a solution for generating the gas, e.g. ammonia, may be introduced by way of a pipe 33 and drip feed device 32 from an overhead tank 31..The print is prevented from rolling out of the compartment into the developing chamber by means of curved metal fingers 39 or wire mesh. In a further position of rotation, the resilient lips. 20 engage an abutment sheet 22 and seal the compartment from the developing chamber and the atmosphere, and a hole 40 in the end disc registers with a pipe 41 through which the gas in the compartment is drawn off. In the final position the developed print drops on to an inclined wall 23 of the casing. The apparatus may be arranged with the axis of the carrier vertical.

Folding boxes; lids and covers; fittings, internal.-A box made by folding a scored cardboard blank is adapted to be supported by the cover in various inclined positions to display the contents. The body of the box is formed by folding each side 2, 2a, Fig. 1, inwards upon itself, the parts 2b extending across the ends 3. Extensions 3a on the ends 3 pass between the folds 2, 2a of the sides. A hinged cover is formed bv bending up sides 5 and an end 4 in a similar way. The extreme edge of the end 4c is held under a tab 7. The sides of the cover are partly cut along lines 6, forming portions that may be torn away, leaving inclined edges, so that, when folded right beneath the box with the part 4a resting against the end 3, the cover forms a wedge elevating one end of the box. Fig. 4 shows a position in which the cover stands vertically, elevating the other end of the box. The parts 4<1> of the sides of the cover are passed between the folds 2, 2a of the sides of the box to give rigidity in this position. Further support may be given by interengaging tongues 10 bent out from the bottom of the box and from the cover, or by gummed-on braces. In another position, the cover stands vertically, as shown in Fig. 4, and the box is suspended in a lower position from the part 4a. The flaps 4' are either torn off or allowed to stand out laterally. The blank may have a flap 8, Fig. 1, to receive advertising matter; this is bent up into an upright position when the box is supported for displaying the contents. The flap 8 may be a separate part inserted between the end of the box and the contents. In a modification, the extensions 2a, 2b are dispensed with, and the sides 2 have terminal extensions with pointed portions, which are folded and passed through L-shaped slots in the end 3 and then opened out; the cover is secured in a similar manner.
