Title: Chlorine-containing polyalkylene glycol phosphonates
Inventor: FRIEDMAN LESTER
IPC: C08G63/692
Filed: 1963-06-06
Abstract: The invention comprises phosphonates of formula <FORM:1011120/C3/1> or <FORM:1011120/C3/2> where R1, R2 and R3 are the residues of a polyalkylene glycol from which the two hydroxyl groups have been removed, n is zero or an integer and m is an integer of 1 or more (see also Division C2) and polyurethanes prepared therefrom.  The phosphonates are prepared by reacting chloral with a phosphite of formula <FORM:1011120/C3/3> preferably in the presence of a basic catalyst such as an amine, phenolate, alkoxide or anoin exchange resin.  Many phosphonates are specified derived from polyethylene, and polypropylene glycols and a polypropylene glycol-ethylene oxide block copolymer.  The polyurethanes may be made by the one of two shot method and may be foamed by the inclusion of water or a halofluoroalkane. Other polyhydroxy compounds may be included, from 5 to 100% of the hydroxyl component being the phosphonate of the invention. Lists are given of suitable isocyanates, isocyanate-polyhydroxyl compound prepolymers, polyhydroxy compounds, basic catalysts, tin compounds, and silicone surfactants.  Reference is also made to the preparation of polyesters and epoxy resins from the phosphonates of the invention.  The polyesters may be derived from maleic or phthalic anhydride, dimethyl terephthalate, fumaric acid or adipic acid.  Specification 1,011,119 is referred to.ALSO:The invention comprises phosphonates of formula <FORM:1011120/C2/1> or <FORM:1011120/C2/2> where R1, R2 and R3 are the residues of a polyalkylene glycol from which the two hydroxyl groups have been removed, n is zero or an integer and m is an integer of 1 or more.

Patent GB-1040829-A (GB)
Title: Process for the separation of solids from suspensions containing them
IPC: B03B9/00
Filed: 1965-05-31
Abstract: Improved separation of solids from suspension, particularly amorphous or crystalline paraffin wax from suspension in hydrocarbon oils, is achieved in a hydrocyclone by the addition of a finely divided solid auxiliary substance which is easier to separate in the hydrocyclone than the solids to be separated, and which does not dissolve in or react with the suspension. Auxiliary substances are preferred which are of smaller particle size than the wax, e.g. of less than 50m , which have a specific gravity differing from that of the oil by at least 2 units and which undergo at least 90% separation; specified substances are iron, barytes, galena, calcite, magnetite and fluorite and, for anhydrous suspension, the water-soluble salts cadmium, cobalt, copper, or magnesium sulphate, silver nitrate, or calcium, barium or zinc chloride having a specific gravity of 3.0-4.7 and used in an amount up to 10% (vol.) based on the starting suspension.  Iron powder of 5-20m  is preferred.  The suspending liquid, e.g. kerosine, gas or lubricating oil may initially be diluted with a low viscosity solvent such as methyl isobutyl ketone, or mixtures of MEK, benzene, toluene and liquid propane, the oil is cooled, the auxiliary substance added to the precipitated wax, and the mixture hydrocycloned.  Hydro-cyclones in series or parallel may be used if desired.  The wax phase on withdrawal may be freed of auxiliary substance by e.g. magnetic separation or water washing, and of solvent by evaporation, while the withdrawn oil, containing no more than 1% by volume auxiliary substance, is worked up by evaporation of solvent and filtering, and is recovered or recycled.

Feeding-appliances for animals. - A dry-mash feeder comprises a trough 1 provided with a twopart lid 4, 5, having baffle plates 7 hingedly connected to the underside of the upper part 4 of the lid near to the lower longitudinal edge thereof. One baffle only may be fitted or, if the trough is divided as shown by a partition 2, a separate baffle plate may be provided for each compartment. The lid is provided with double hinges 9 and, in filling the trough, the lid is pushed back on these hinges till the baffles are clear of the trough ; the material is then poured in and the lid brought forward so that the baffles rest on the top of the mash, leaving only a narrow slot 11 between the lower edges of the baffles and a longitudinally arranged lip 8 at the lower side of the trough through which the birds can peck at the meal. As the feed is consumed the baffles swing back into vertical position. Instead of being attached to the lid the baffles may be hung on a rod secured in the end walls of the trough. A double-sided trough may be used. A turn-button may be fitted to the lid to hold the baffles in inoperative position.

Title: Process for the artificial age-hardening of aluminium alloys
IPC: C22C21/08
Filed: 1950-09-25
Abstract: A process for warm age-hardeing aluminium alloys which age-harden spontaneously and quickly after quenching from the solution temperature and such age-hardening is incompletely removed at warm age-hardening temperatures comprises bringing the alloys from the solution temperature to that of warm age-hardening and maintaining them at that temperature for such time that no modification of the supercooled solid solution takes place at a temperature above or below that of warm age-hardening.  The alloys may be quenched to the warm age-hardening temperature in a salt bath and maintained therein until age-hardening is complete, or the time during which they are held at the age-hardening temperature is short compared with the total time to complete warm age-hardening and the alloys are kept for a time at room temperature before completing the age-hardening.  The alloys may be quenched to a temperature below that of warm age-hardening for a short time and reheated to warm age-hardening temperature before storage at room temperature prior to completing the age-hardening process.  The temperature of warm age-hardening may be 150-220 DEG C. and alloys containing 0,3-1,5 per cent Mg : 0,2-1,5 per cent Si : 0-1,5 per cent Mn and the balance Al, or 0,25 per cent Cu : 1,17 per cent Mg : 0,7 per cent Si : 0,25 per cent Cr : and 97,63 per cent Al, may be used.

Bottling.-Relates to apparatus for filling and sealing bottles &c. under vacuum of the type described in Specification 286,756. According to the invention the admission of fluid to the sealing ring 45 and its exhaustion therefrom, and the exhaustion of air from the chamber 36 are operated bv the movements of the bottle platform 24. The platform is raised by a spring 25 and controlled by a foot-lever 23. Two fixed positions are provided for the platform by teeth 28, 29 in a lever 26 which engage the edge thereof. The lever 26 is controlled from a handle 30. The vacuum in the chamber is produced by the passage of water under pressure through the pipe 35. The platform 24 is connected by a rod 50 through a rack and pinion to a plug-valve 56 which controls the passage of water through the pipe 35. On the first upward movement of the platform to the tooth 29 the bottle neck is placed within the ring 45 and on the downward movement therefrom liquid is admitted to the ring and to the vacuum cylinder 34 to exhaust the chamber 36 and the bottle. On the next upward movement the valve 56 remains stationary, and on the next downward movement the ring 45 is exhausted. The second upward movement is not interrupted by the stop 29 so that the bottle is capsuled as it advances into the tapered head 38.

Filed: 1929-08-01
Abstract: 317,444. Stig, T. J. Nilsson-. Aug. 16, 1928, [Convention date]. Insulation; inductor-machines; high-frequency machines; machines with two or more armatures; cores.-In order to reduce iron losses, the armature windings are wholly or partly inserted in a rigid frame or former of insulating material between the co-operating magnetic parts of the machine. The invention is particularly applicable to high frequency generators of the inductor type. As shown in Fig. 3, the high frequecy winding D is disposed in an insulating frame C in such a way as to be nearer the slotted rotor B than the stator core A. If the rotor has salient poles, the slots M between poles which accommodate the field winding should be equal in width to an even number of tooth pitches. An additional low frequency or continuous current winding E may be located in the insulating frame C or in a separate frame and this winding may co-operate with the main field to produce rotation. In a modification, Fig. 1, the insulating frame may be separate from the magnetic structure A, B which is in motion relatively to the armature winding. The high frequency conductors consist of finely subdivided enamelled copper wire and are drawn into the slots in the formers. The rotor slots are filled with bronze wedges to reduce windage losses and to retain the magnet windings in position.
