Title: Improvements in or relating to means for cushioning motion of a railway vehicle axle
IPC: B61F15/18
Filed: 1934-10-26
Abstract: 439,911. Railway - vehicle axles; bearings. FRANKLIN RAILWAY SUPPLY CO., 60, East 42nd Street, New York, U.S.A.- (Assignees of Zouck, G. H.) Oct. 26, 1934, No. 30779. Convention date, Nov. 4, 1933. [Class 103 (vi)] [See also Group XXXIV] Lateral motion of the axles of a locomotive or other railway vehicle is provided for by allowing the axles to be displaced laterally in the axle-boxes which, in relation to the vehicle frame, are permitted only a guided vertical movement. In the construction shown in Figs. 2 and 4 the inner and outer races 25, 26 and rollers 27 of the anti-friction bearing are fixed on the axles between spacing rings 28, 30, the other edges of which bear against an axle shoulder 14 and the wheel hub 31 respectively. Sufficient clearance 39 is provided on each side of the bearing to permit the requisite axial displacement of the axle and bearing relative to the axlebox 16, such displacement causing spring controlled plungers 40 at one or other side of the vehicle to be actuated against the effort of springs 45. Conveniently, six plungers may be associated with each wheel, while the lower parts 16<a> of the axle-boxes are preferably made removable and secured in position by wedges 37. In place of a single spring 45, two or more springs having different lengths or different strengths may surround each plunger 40; or, by arranging each spring between movable washers 53, Fig. 7, associated with abutments 50, 50<1>, all the springs are compressed in whichever direction the axle is displaced. According to modifications, the top or cover of the axle-box forms a loadtransmitting member and moves with the bearing, or an additional cap may be inserted between the outer race and the top of the axle box. In a still further construction, the outer surfaces of the races are made spherical so as to accommodate the rocking movements of the axle in a vertical plane caused by track inequalities &c.

Title: Encapsulation process
IPC: B01J13/10
Filed: 1973-06-28
Abstract: 1442175 Making microcapsules L J M DE POZUELO DAUNER 28 June 1973 30883/73 Heading B8C Microcapsules containing hydrophobic liquid core material are prepared by emulsifying the core material in an aqueous dispersion of a naturally-occurring, hydrophilic, film-forming colloid material, dispersing the resulting emulsion in an aqueous solution of a protective colloid which serves to prevent agglomeration of the dispersed particles of core material surrounded by film-forming colloid material and cooling the resultant dispersion to gel the filmforming colloid. An agent inhibiting chainlengthening of the colloid during its transformation from sol to gel may be added to the emulsion, i.e. formaldehyde sulphonic acid/sodic naphthalane salt condensate and the microcapsules formed may be hardened by conventional means. Suitable film-forming colloids are gelatin and gelatin/gum arabic and suitable protective colloids include carboxymethyl cellulose. The encapsulated hydrophobic liquid may include colouring and colour-forming materials rendering the product useful in preparing record transfer sheets and the like.
