Patent GB-884205-A (GB)
Title: Acrylic cation-exchange resins
IPC: C08F20/62
Filed: 1958-03-11
Abstract: Cation-exchange resins are made by copolymerizing a mixture of acrylic and/or methacrylic acid and a cross-linking agent which is a long chain essentially linear polymer comprising or consisting of unsaturated ester units of the formula: <FORM:0884205/IV (a)/1> wherein R and R1 are hydrogen or methyl, i.e. homopolymers of allyl or methallyl acrylate or methacrylate or copolymers thereof with other monomers, e.g. C1-C4 alkyl methacrylates, the amount of cross-linking agent employed being such that the resultant resin is capable of absorbing a large amount of water when contacted therewith, but is sufficiently cross-linked to be insoluble, e.g. 0,1 to 5,0 mole per cent of cross-linking agent based on the total polymerizable material used.  Polymerization may be carried out in bulk or suspension, but is preferably carried out in solution in a solvent such as benzene, toluene, acetone, dioxane and isopropanol, with the aid of a catalyst such as ozone, ozonides, acetyl, lauroyl, stearoyl benzoyl and ditert-butyl peroxides, tert-butyl hydroperoxide and the barium salt thereof, tert-butyl perbenzoate, ditert-butyl diperphthalate, barium, sodium and hydrogen peroxides, azoisobutyronitrile, perborates, persulphates and perchlorates. The products may be employed as bulk laxatives and as buffering agents. Specifications 731,226, 867,396, 867,397, and 867,398 are referred to.

Title: Resilient bearings for eliminating or damping vibration
IPC: F16C27/06
Filed: 1963-02-28
Abstract: 1,025,402. Resilient bushings. SOC. APPLICAZIONI GOMMA ANTIVIBRANTI "S.A.G.A." S.p.A. Feb. 28, 1963 [Nov. 7, 1962], No. 8008/63. Heading F2S. A resilient support for absorbing radial vibrations, e.g. of rotary transmission shafts of motor vehicles, comprises an annular elastomeric member 10 having circular V- shaped grooves 13, 14 at different mean diameters in its opposed side faces 11, 12, the grooves mutually overlapping at an intermediate axial portion 16. The member 10 is vulcanized to an inner metal bushing 18 which provides a bearing for a transmission shaft and to an outer bushing axially-extending grooves 22 being formed between the bush segments 21a, 21b... to facilitate drawing together of the segments so that the member 10 can be radially precompressed to the required degree to provide the correct vibration damping conditions. In a modification, Fig. 3 (not shown), the outer bush is continuous and the inner bush is segmental with intermediate axially-extending grooves on the inner face of the member 10, it being advantageous to have a shaft radius greater than that of the inner bush to radially precompress the member 10. Alternatively, the outer bush may be made smaller to place the member 10 in precompression.

Title: Improvements relating to directional propagation and reception of electromagnetic waves
IPC: G01S1/02
Filed: 1941-07-10
Abstract: 581,762. Directive radio signalling. LELAND STANFORD JUNIOR UNIVERSITY, BOARD OF TRUSTEES OF. July 10, 1941, No. 8762. Convention date, July 10, 1940. [Class 40 (v)] Apparatus for directional transmission or reception of electromagnetic waves comprises a wave guide or radiating resonator having a number of angularly-disposed branches with slots or apertures or other means for interchanging energy between its interior and its exterior. Two or more of such combined resonators may be arranged side by side to increase the directivity, as in a broadside array of radiating antennµ. The apparatus may be given a scanning movement as in radiolocation. Fig. 1, which illustrates the principle of the invention, shows a wave guide producing a conical wave front, the guide 1 being energized by a doublet 3 and perforated at 5 to allow energy to radiate into the surrounding space, the guide being several wave-lengths long and having several perforations within a wavelength. Fig. 2 shows two guides 31, 31<1> energized in phase by doublets 3, 3<1> and perforated as shown, thereby producing a fanshaped beam which is flat in the plane of the paper and fan-shaped in the plane at right angles thereto. The perforations or the width of the slot may vary as a function of the distance along the guide, to determine the directivity. Any energy which reaches the ends of the guides may be absorbed at 9, and the guide may have a longitudinal fin extending radially inwardly to prevent rotation of the plane of polarization. Fig. 10 shows apparatus for radiolocation comprising two rectangular guides 41, 41<1> energized in phase by a quarter-wave antenna 44 and mounted so that they may be moved in azimuth and elevation by motors 42, 43. The slots 15, 15<1> are formed between ground plates 35, 35<1> which are extensions of the guide proper. The angle between the guides may be adjusted by rod 11 and energy reaching the end of the guides may be absorbed by carbon plates 19 and reflected by plates 33.

The wings on certain of the surfaces are axially offset from the wings on the other surfaces and the junctures of the wings and the surfaces are along straight lines. As shown, the outer free edge 50 of each wing is curvilinear and there is a rigid tapered nose portion 60 through which the recesses 40 are continued to provide means for accommodating an installation tool; a spacer portion 20 carries a secondary head 22. The lower surfaces of the wings are upwardly tapered, and the incremental spacing of the wings between adjacent surfaces may be such as to approach a helical disposition. In a modification, the nose portion 60 has an axial tool gripping extension.
