Title: Improvements in and relating to polyepoxide compositions
IPC: C08G59/42
Filed: 1959-04-23
Abstract: A heat curable composition comprises 4vinylcyclohexene dioxide and a polycarboxylic acid anhydride in amount such that 0,1 to 0,8 carboxyl equivalent of the anhydride is present per epoxide equivalent of the dioxide.  Suitable polycarboxylic anhydrides can be represented by the formula: <FORM:0868432/IV (a)/1> wherein X represents two or more carbon atoms interconnected by single or double bonds to which there can be attached alkyl, hydrogen, hydroxyl, chloro, iodo, bromo or cyclic groups; carbon atoms interconnected by oxydicarbonyl groups; or cyclic or phenylene groups to which one or more oxidicarbonyl groups can be attached, a number are listed.  Mixtures of anhydrides, polymeric anhydrides or mixed polymeric anhydrides of sebacic, adipic, pimelic, cyclohexane-1, 4-dicarboxylic, terephthalic and isophthalic acids can also be used.  Catalysts which may be added to promote curing are mineral acids, sulphonic acids, metal halide Lewis acids, alkali metal hydroxides and amines.  Mixture with the curable composition can be effected in an organic solvent.  There may also be employed active hardeners, which are organic compounds containing two or more groups reactive with epoxy groups. Specified hardeners are polycarboxylic acids, polyesters containing free carboxyl groups, (preferably prepared from di-, tri- or tetra-hydric aliphatic or oxa-aliphatic alcohols), and polyols.  A number of specific catalysts and hardeners are listed. The invention also includes solutions of the curable and partially cured compositions in, for example, xylene, methyl isobutyl ketone, butyl acetate, ethyl acetate, toluene and amyl acetate, which, alone or with the addition of wetting or thixotropic agents, can be used as coating compositions.  In Examples (1) 0,05% by weight of dimethylbenzylamine is added to a mixture of 4-vinylcyclohexene dioxide, maleic anhydride and glycerol containing 0,67 carboxyl equivalent of anhydride and 0,33 hydroxyl equivalent of polyhydric alcohol per epoxy equivalent of diepoxide.  After gelling, the product is postcured by heating; (28) 4-vinylcyclohexene dioxide (0,1 carboxy equivalent) and chlorendic anhydride (1,0 epoxy equivalent) are stirred together at 26 DEG C. and the mixture is then gelled and cured by heating; (51) 4-vinylcyclohexene dioxide and polyadipic anhydride, in amounts providing 0,5 carboxyl equivalent of anhydride per 1,0 epoxide group of diepoxide were heated at 160 degrees to give a viscous polymer.  A solution of this in methyl isobutyl ketone is used as a coating composition.  The polyadipic anhydride is obtained by refluxing a mixture of adipic acid and acetic anhydride with continuous removal of acetic acid at the still head, followed by recovery of the polyanhydride by distillation of excess acetic anhydride.

(3) The rollers 52, Fig. 10, are of cardboard or similar material having longitudinal slots 54, for the reception of an end of the paper-strip. The delivery-roller may serve merely as a support for an ordinary paper-carrying tube. The rollers are supported by the arrangement shown in Fig. 14. Jaws 56 arc carried by plates 12, 13 and are provided with projections 59 which engage in slots 53 in the tubes ; those jaws connected to the plate 13 are connected to sleeves 57 slidable on shafts such as 14 or 15 against the action of springs 61 which thus serve to brake the rotation of the roller.

Title: A computing device for calculations relating to machine tools
IPC: G06G1/14
Filed: 1951-06-15
Abstract: 715,477. Calculating-apparatus. GRANDADAM, R. C. M. E. June 15, 1951 [June 29, 1950], No. 14240/51. Class 106 (1) A logarithmic calculator relating the factors involved in the optimum use of machine tools, for use in allocating work to the machines available and determining their adjustment, comprises a base A, an element B movable thereon, a group of characteristic curves 5 on the element B, a second group of characteristic curves 4 either upon the element B or the base A, another characteristic curve 6 joining the intersections of the two groups of curves, a slide-rule C movable with respect to the base A and element B, and an index 16 on the rule co-operating with the curves. The element B may be a rectilinearly movable slide, the groups of " curves " then being straight lines, but is shown as a circular disc rotatable above its centre C1, and the slide-rule is rotatable about a point C2 offset from C1. The base is marked with a scale 1 for depth of cut read against a pointer 9 on the slide-rule stock 8, and with a scale 2 for " coefficients R2 ": these are empirical values dependent upon tool and workpiece characteristics and upon the conditions of machining, and are tabulated on the back of the apparatus. The groups of curves 4 and 5 are both marked with values of feed per revolution (of the cutting tool), curves 4 representing optimum values as regards the cutting tool, and curves 5 optimum values as regards the machine. The curve 6 joining the intersections of corresponding curves 4 and 5 consequently represents values of feed per revolution making best use of both machine and tool. The disc B further has a scale 7 of empirical values characteristic of individual machines (power and condition), this scale co-operating with the scale 2 of co-efficients R2 on the base A. The slide-rule C comprises two slides 11 and 15 working one within the other, and both within the stock 8. The sliderule is used alone for calculations involving only time, feed per revolution, speed and depth of cut, these factors being represented respectively by the scales 14, 18, 12 and 17 on the two slides which are used in conjunction with a cursor 20. In other calculations involving the apparatus as a whole, the scale 17 is used for values of tool or workpiece diameter, the outer slide 11 is adjusted against a scale 10 of empirical values of a "coefficient R1" (similar to and based on the same factors as R2) on the stock 8, and the index 16 on the inner slide 15 is read against the scales 4, 5 or 6, generally the scale 6. The cursor 20 has two index lines for reading values of time on scale 14 alternatively in minutes and hundredths of an hour.

Title: Continuous fermentation process and apparatus for the production of alcoholic beverages
Inventor: JOHNSTON ROY HARRY WILLIAM
IPC: C12C11/00
Filed: 1961-10-20
Abstract: <PICT:1004693/C6-C7/1> Brewer's wort is introduced at a controlled rate through a feed line 1a into a vessel 1 wherein yeast growth is continuously maintained under aerobic conditions, and partially fermented wort, carrying the yeast in suspension, is fed from vessel 1 through line 3a to the base 3 of a column fermenter 13 in which the wort is fermented under anaerobic conditions; some unfermented wort may be passed direct to the fermenter through a line 1b.  For the generation of foam, wort is withdrawn by a diaphragm pump 4 into a pressure vessel 5 in which it is supersaturated with carbon dioxide delivered by a line 5b at an absolute pressure of about 60 lbs per sq. inch; the pressure release at the valve 7 of the carbonated liquid returned under pressure through line 6b, produces foam in the liquid entering the base 3 of the column fermenter through line 7a. A photo-electric head 11 linked electrically by the relay 12 with an electromagnetic valve 6 ensures that the flow of liquid from vessel 5 to the column fermenter 13 is such as to maintain constant the level of the liquid/foam interface 10; resultant changes in the level of liquid in the pressure vessel 5 are detected and rectified by a probe 9, which is linked electrically by a relay 8 to the pump 4.  After fermentation has been completed to the desired extent, the foam is passed to a settling region 14. Finally, beer and yeast are separated in vessel 16, the beer being drawn off by a line 16a while the extracted yeast is pumped by a pump 17 to an outflow 17a and return line 17b.  The carbon dioxide emerging from the system at 14a may be collected and re-cycled for use in the foam generation. Specifications 835,964 and 894,899 are referred to.
