Title: Improvements in and relating to dry-cleaning apparatus
IPC: D06F43/08
Filed: 1948-06-28
Abstract: <PICT:0651572/III/1> In a dry-cleaning apparatus comprising the usual openwork drum 3 enclosed in a casing 2 communicating with a distillation apparatus 16 from which the solvent is supplied under gravity, the casing 2 is mounted on a box-like pedestal 1 housing an electric motor 9 for driving the drum 3 and a separately-driven blower 7, which latter is in communication with a suction aperture at the upper part of the <PICT:0651572/III/2> casing, the arrangement being such that during cleaning the drum can be rotated with the blower inoperative and during subsequent drying the solvent vapours can be drawn by suction out of the casing with the aid of the blower. A reversing motor with change-speed gearing 9a is used and after removal of the dirty solvent through a draining pipe 11, followed by a rinsing in clean solvent, the bulk of the solvent is removed from the articles being cleaned by running the drum at a higher speed of revolution. The speed is then increased for the drying operation and the blower put in operation.  During the drying a cover 4b is removed from the hollow shaft 4 supporting the drum, which is journalled in an extension 2a of the casing, so as to draw fresh air through the drum and the articles therein.  The drum is supported on the opposite side by a journal 4a in a bearing mounted in the wall of the casing. The diameter of the drum is greater than its length, and the drum may be subdivided.  The draining pipe 11 is connected to a still 15 in the lower part of the distillation apparatus through a separator 13 for removing buttons &c. from the dirty solvent.  The vapours from the still ascend through a pipe 18 to a water-cooled coil 19, the condensate collecting in a reservoir 21.  From the latter, solvent may be supplied to the lower part of the casing 2 through a valved pipe 26.
Patent GB-942465-A (GB)
Title: Improvements in or relating to the production of alkyl resins
IPC: C08G63/82
Filed: 1960-05-17
Abstract: Alkyl resins are made by reacting (a) an epoxyalkyl ester of an alkane monocarboxylic acid in which the carbon atom directly attached to the carboxylic group in tertiary or quarternary with (b) a polycarboxylic acid or its anhydride. Preferred monocarboxylic acids are alpha-alkyl-alkane monocarboxylic acids and alpha-alpha-dialkyl-alkane monocarboxylic acids containing 4-20 carbon atoms and obtained by reacting carbon monoxide, water and a mono-olefine. Specified epoxyalkyl esters are the glycidyl, 2:3-epoxybutyl, 3:4-epoxybutyl, 2:3-epoxyhexyl, 1-ethyl -2:3-epoxyhexyl and 2:3-epoxy-4:5-diethyl dodecyl esters. Specified polycarboxylic acids are malonic, succinic, glutaric, adipic, azeleic, sebacic, diglycolic, maleic, fumaric, phthalic, isophthalic, terephthalic, tetrahydrophthalic, hexahydrophthalic or dimerized fatty acids and Diels-Alder adducts of maleic anhydride and dienes (e.g. terpenes or cyclopentadiene).  The reaction may be effected in the presence of a polyhydric alcohol, e.g. pentanediols, hexanediols, di- and tri-ethylene glycol, di-hydroxyalkoxy benzene, polyhydroxy-polyalkylene polyusulphides polyhydroxy-polyalkylene sulphonides, glycerol, trimethyol propane, pentaerythritol, pentanetriols or hexanetriols or a mixture of a dihydric alcohol and a higher polyhydric alcohol, e.g. glycerol and diethylene glycol, triethylene glycol, 1:5-pentane diol or 1:6-hexanediol; or triethylene glycol and trimethylol propane or pentaerythritol. The reaction may also be effected in the presence of a monocarboxylic acid, a Lewis base (e.g. a hydroxy compound, acidamide, mercaptan, alkyl disulphide or sulphoxide), an alkali metal hydroxide, a quaternary ammonium base or an amine, a Friedel Crafts catalyst(e.g. boron trifluoride and a complex thereof with an ether or an amine), a phosphonic acid, a sulphonic acid, or a solvent. The resins are useful in the manufacture of coating compositions possibly with the addition of a solvent (e.g. xylene), a pigment (e.g. titanium dioxide), or a phenolurea or melamine-formaldehyde resin. In examples, the glycidyl ester of an alpha-alkyl-alkane monocarboxylic acid was reacted with 1(A)-1(D)) and 1(G) phthalic anhydride and glycerol, 1(E) first with the acid from which the glycidyl ester was derived and then with phthalic anhydride and glycerol; 1(F) terephthalic acid; (2) phthalic anhydride, glycerol and triethylene glycol; (3) phthalic anhydride and glycerol. Specification 936,808 is referred to.

Abstract: 120,963. Spencer, A. F. Nov. 26, 1917. Sterilizing milk &c.-An apparatus for sterilizing milk is so arranged that the apparatus can be sterilized before introducing the milk, by means of heated air, and that the milk is passed through the apparatus and forced into bottles by air pressure. The air passes from a pressure reservoir a by a pipe a<2> through a heater b and coolers c, and thence to the milk-sterilizing apparatus. This consists of two vessels d, e connected by pipes as shown, and provided with stirrers, gauges, and blow-off pipes and taps d<5>, e<5>. Air at 300‹ F. is first passed through the whole apparatus. The coolers c are then put into action and the temperature of the air reduced to 160‹ F. Milk is then admitted to the vessel o and heated to about 160‹ F. for 15 minutes. The blow-off tap e<5> is then closed and the tap d<5> opened, whereupon the milk is forced by air pressure into the vessel d, where it is again heated. By leaving a small quantity of milk in the vessel e, sediment and gases are prevented from entering the vessel d. The milk is again heated in the vessel d, and then forced by air pressure through a cooler k and taps f<1> into bottles f. The taps f<1> are then closed and the bottles removed for use.

Title: Improvements in or relating to cooling systems for dynamoelectric machines
IPC: H02K9/10
Filed: 1927-07-04
Abstract: 274,450. Akt.-Ges. Brown, Boveri, et Cie- July 15, 1926, [Convention date]. Dynamos, cooling and ventilating.-In a closedcircuit cooling system for electrical machines, the coolers are built into the two longitudinal sides of the machine casing or bedplate so as to form a V, the apex of which is below the machine while headers at the upper ends of the V limbs are slightly above and accessible from the engine-room floor for cleaning the coolers. Fig. 1 shows the application to a dynamo in which the coolers 2 are mounted directly in the machine casing, the air path being, as shown by the arrows, such that the cooled air or gas flows freely into the completely enclosed space between the foundation columns. The coolers are cleaned through the upper headers 3 from the engine-room floor by opening the water supply pipes 5 sufficiently to give the cleansing water and passing the mud or incrustation into the mud chambers 7 and mud pipe. 8, the lower headers 4 being opened for this purpose by means of gear 6. The cleaning may thus be carried out without much reduction in the normal action of the coolers. To enable the coolers to be removed for inspection or repair, flaps 13 may be so arranged as to prevent short-circuiting of the air current, and in these circumstances the reduced action of the cooler is increased by working with fresh air which enters at 11 and leaves at the point 10. In an alternative form, the coolers are mounted V-wise in a separate bed plate so that the machine may be removed independently of the cooling system, the mud chamber being formed integrally with the bedplate. Specification 273,333 is referred to.

Abstract: 117,565. Maina, J. Dec. 4, 1917. Gauging-devices; driving machines. - Relates to apparatus of the type having pairs of fingers which, on the completion of the work, are automatically applied to it, one finger of each pair being of a length to pass the work if not too large, and the other of such a length that it is arrested if the work is not too small. A friction wheel j, driven by the lathe &c., rotates the disk k at a speed such that the wheel g makes one revolution during the progress of the work. When the wheel g completes a revolution, a cam on it raises a lever 5 on a spindle carrying at its other end a quadrant w in gear with a pinion 2 on a spindle f. On this spindle are keyed rings o each of which has a projection p which, when the spindle is rotated, frees a projection s on a ring r mounted on ball-bearings and carrying a pair of gauging-fingers. The rings r are thus free to rotate so that the fingers are applied to the work. Each ring r has a conducting segment 8 which, if the work is to gauge, comes to rest under a pair of contacts 9. When the spindle f is rotated, the current to the motor driving the machine is switched from the main circuit to a circuit including the contacts 8, 9. Should the work be to gauge throughout, the current passes to the motor which continues to drive the machine. If the work is not to gauge throughout the circuit is broken at one or more points and the machine is stopped. In a modification, the contacts control a local circuit which, when broken, stops the machine

[Also in Division H1] A printed circuit having the conductive elements 31, Fig. 5, impressed into the surface of the supporting substrate 41, is made by initially heating and compressing an assembly consisting of a dielectric substrate of epoxy resin, e.g. a resin based on bisulphenol A or a novolak type resin, reinforced with at least two layers of glass, sandwiched between two metal foils, e.g. of copper, aluminium or nickel, coated with adhesive on their inner surfaces. The adhesive may be a mixture of a phenol- or cresol-formaldehyde resol resin with an acrylonitrile butadiene copolymer or an epoxy resin mixed with an elastomer. The desired wiring pattern is then formed in the metal layers by etching or photoetching. Subsequently the assembly is split between the two layers of glass and the individual sheets applied to one or both sides of an insulating supporting base 51, e.g. of wholly or partly cured epoxy resin which may be reinforced with a mat or tissue form of glass fibre, by heat and pressure so that it is adhered to the base and the conductive elements are pressed into the surface of the substrate. The epoxy resin substrate is partly cured during the initial heating and compressing operation and completely cured in the final such operation. The final assembly may be non-planar, its shape having been formed by the final press or the supporting base may have been provided with a non-planar form initially.
