Filed: 1946-01-01
Abstract: 620,666. Piece boards. QUARMBY, F. R. Jan. 1, 1946, No. 28. [Class 42 (ii)] A rolling or lap board, used to form the centre of a roll of fabric, is formed by applying to a filler of layers of corrugated paper, two U-shaped cover strips embracing the longitudinal edges of the filler, gradually forcing the cover strips inwards towards one another and securing them in position by adhesive strips. The filler a which may comprise three layers of backed corrugated paper, with the corrugations of the centre layer perpendicular to those of the remaining layers, has two strips b, b<SP>1</SP> of a width equal to, or slightly greater than, half the girth of the filler, applied to its longitudinal edges, by folding them and placing them within U-shaped metal formers c, which are then brought over the edges of the filler and caused to approach each other by passing between converging series of hollow-faced rollers d and e. End-filling pieces of wood are then applied, and the assembly secured together by adhesive strips g<SP>1</SP>, h<SP>1</SP> applied by rollers g, h, after which it passes between further rollers where it remains for a short period while the adhesive sets. A paper or like end cap or strip is then pasted over each end.

Filed: 1938-11-25
Abstract: 509,762. Unsaturated acids. DISTILLERS CO., Ltd., and STAUDINGER, H. P. Nov. 25, 1938, No. 31. [Class 2 (iii)] Unsaturated acids such as crotonic acid are produced by the oxidation with air or oxygen of the corresponding aldehydes in the presence of an organic acid miscible with the aldehyde and of an organic peroxide such as benzoyl peroxide. The invention is described with reference to the oxidation of crotonaldehyde in the presence of acetic acid, but propionic and .butyric acids are also suitable and methacrylic acid may be made in a similar manner from methylacrolein. The crotonic acid may be separated from the reaction mixture by filtration or by distillation. In examples, (1) air is passed through glacial acetic acid containing some benzoyl peroxide, and the product is added to crotonaldehyde, air being passed through the mixture at 25‹C.; the crystals of crotonic acid are separated by filtration or the excess crotonaldehyde and the acetic acid are removed by distillation under reduced pressure ; (2) a mixture of crotonaldehyde, acetic acid and benzoyl peroxide is fed down a packed column in counter-current with air.

Title: Improvements in or relating to the cooling of moulding sand
IPC: B65G69/20
Filed: 1959-01-01
Abstract: 902,327. Cooling granular material. FISCHER A. G., GEORG. Jan. 1, 1959 [Jan. 30, 1958], No. 76/59. Class 64 (2). A method of cooling foundry sand comprises the steps of pouring the sand on to an airpermeable support so as to form a loose layer and passing air upwardly through the support and layer so that the pressure drop through the support amounts to at least 5% of the total pressure drop through the support and sandlayer. The apparatus comprises an endless belt 10 having uniformly distributed ports therein, the lower side of the belt being associated with a compressed-air reservoir 11 and the upper side with means for spreading a uniform layer loosely thereon. Hot sand is fed by a conveyer 5 into a box 1 and, in falling, is moistened by spray from a pipe 31. Rotary paddles 2 mix the sand and feed it into a pivotally-suspended hopper 7 whence it falls through a vibrating shoot 8 which distributes it on the belt 10. The belt comprises sections 30 sealed together by rubber strips. Compressed air is supplied by pipes 12 to the reservoir 11 which is sealed against the underside of the belt 10. Compressed air is also supplied to apertured pipes 20, 21, above and below the return-run of the belt, to remove the last traces of sand. All the sand falls on to an endless conveyer 14. The ports 25 (Fig. 6) may be protected by elongated U-shaped covers 26. Specification 798,864 is referred to.

Dyeings with dispersion dyestuffs on materials of aromatic polyesters are levelled by treatment during or after dyeing with polyalkylene glycol ethers of the formula wherein R 1  and R 2  are each an alkyl of 6-18 C, cycloalkyl, aralkyl or aryl hydrocarbon radical or R 2  may also be a lower alkyl radical or a hydrogen atom, R 3  and R 4  may both be hydrogen or one of them is a methyl radical and n is an integer from 8 to 14. Mixtures of the said ethers may be employed especially compounds where R 2  is H or methyl with compounds where R 2  is an aralkyl radical. The ethers may be prepared by known methods from phenols bearing the appropriate substituents, e.g. isononyl, cyclohexyl, phenyl or benzyl radicals,by reaction with ethylene oxide and/ or propylene oxide. The ethers or mixtures thereof may also be used together with polyalkylene glycol esters of fatty acids,e.g. oleic acidhexa- or octaethylene glycol ester. The ethers may be appliedwith the dyestuff from dyebaths at 98-130C. or from separate after-treating baths which may contain 0.2-2% by weight of the material to be treated. Examples are given in which the following ethers are employed either singly or as mixtures Specifications 470,181 and 787,379 are referred to.

Title: Time division multiplexer circuit

Abstract: PURPOSE:To form the time division multiplexer circuit economically to the utmost by allowing single time division multiplexer circuit to act like a multiplexer section or a demutiplexer section depending on a switching control operation of a changeover control means. CONSTITUTION:A multiplexer means 120 applies time division multiplex to N-sets of input low speed digital signals in the designated order to provide an output of a set of high speed digital signal. A demultiplexer means 130 applies time division demultiplex to a set of input high speed digital signal in the designated order to provide an output of N-sets of low speed digital signals. A changeover control means 140 gives N-sets of low speed digital signals received from an input signal path 101 and (N-1)sets of input output signal paths 103 to the means 120 and outputs the high speed digital signals to an output signal path 102 to act like a multiplexer. Furthermore, the means 140 gives the high speed digital signal from the input path 101 to the means 130 to output one set of low speed digital signal to the output path 102 and outputs the remaining (N-1) sets of low speed digital signals to the (N-1) sets of input output signal paths 103 respectively to act like a demultiplexer.
Patent AT-A12493-A (AT)
IPC: F24H9/12
Filed: 1993-01-26
Abstract: A heating radiator valve (1) has an insertion (8) which may be secured to a connection piece (6) and which contains a valve seat (15) with which a thermostatically actuated closing body (14) cooperates. The heating medium is conveyed to the valve seat (15) through a hollow extension (18) of the insertion (8) or the connection fittings (2). The extension (18) extends along the same axis as the insertion (8). After flowing through the valve seat (15), the heating medium flows into a chamber (23), then in the axial direction of the insertion (8) into an annular space (25) located between the connection piece (6) and the extension (18), through a return piping (21) constituted of axial channels (22) shaped in the material of the insertion (8). The valve seat (15), the closing body (14) and the chamber (23) are rotationally symmetrical with respect to the axis of the insertion (8); when the valve is open, they delimit a ring-shaped discharge slot for the heating medium. A construction which can be universally used, which is not prone to obstruction and which favours the flow of the heating medium is thus achieved.

Title: Purazoles and pyrazolo-3 4-d-pyrimidines xanthine
Inventor: RONALD MORTON CRESSWELL
IPC: C07D231/38
Filed: 1967-07-10
Abstract: Process 3-Amino-4-carboxamidopyrazole (V) is used in the synthesis of pyrazolo (3,4-d)-pyrimidine derivs. such as Allopurinol (I). These compounds inhibit xanthine oxidase in vivo and are active in the treatment of gout and other conditions where the decrease of purine oxidation is desirable. The new process is more economical and gives a purer product even without isolation of (V). The first reaction between (II) and (III) is usually carried out in a polar solvent such as water or preferably lower alcohol, at room temperature. The product (IV) may be isolated but the preferred method is to react (IV) direct with hydrazine without isolation. Product (V) is isolated in very pure form and may be reacted with formamide to give Allopurinol (I) or with urea to give (VI).
