Patent GB-402813-A (GB)
Title: Improved method of rivetting and an improved rivet for use with the method
IPC: A47C3/02
Filed: 1932-06-08
Abstract: 402,813. Setting and making tubular rivets. HUCK, L. C., 541, Lincoln Road, Grosse Pointe Village, Michigan, U.S.A. June 8, 1932, No. 16159. Convention date, June 17, 1931. [Class 43.] A method of securing a tubular rivet comprises inserting the rivet with a shank or mandrel therein in an opening in a structure to be riveted, and while an end thereof is held against expansion exerting compressive forces thereon by longitudinal movement of the mandrel to bulb outwardly a portion of the tubular member between the said end and the structure to form a head having an annularly uninterrupted wall. A rivet comprises an outer tubular member 10, Figs. 4 and 5, and an inner shank member 13, and is secured by gripping the projecting portion 16 of the shank and pulling it outwards while supporting the head 11 with an abutment, thereby bulbing a portion 19 of the tube. The shank, which is a force fit in the tube or secured thereto, may be cut off flush with the head 11. The shank may be recessed at 22 to form a lock between the two members in the riveting operation. The head 11 may be omitted and the tube extended at 25, Fig. 6, a second corrugation 27 being formed in this case. In a further modification the diameter of the tube is reduced over a short length at its outer end, a corrugation 37, Fig. 10, being initially formed at this portion after which the main bulbed portion 40 is formed as in the other modifications. Screw threads or grooves 35 on the shank co-operate with similar formations on the gripping tool. The shank is adapted to break at the necked part 32, the bevel 34 corresponding to the surface of the head 11. A rivet may be formed by drawing the two members through a die 52, 53, Fig. 13, to force an enlarged end 50 into a groove 22 in the shank. A similar step may be effected by rolling or swaging. Alternative methods of holding the end against expansion comprise rolling or hammering an enlarged end 60, Fig. 17, to reduce it to the diameter of the rest of the body and to strengthen it, or heat treating the end. Details of the dimensions of the rivets are given in the Specification.

Phenothioplasts are obtained by first activating a molten phenol by adding a basic phenate or a basic substance which forms a basic phenate with the phenol, and then condensing the phenol with a dithiolpolythioether by slowly adding the dithiolpolythioether to the phenol. The phenol may be hydroxybenzene, metacresol, paracresol, ethylphenol, propylphenol, butylphenol or resorcinol. The phenate may be sodium phenate and the basic substance may be sodium or potassium hydrosulphide, diethylamine, dimethylamine, diethanolamine, morpholine, pyrrolidine, or piperidine. The dithiolpolythioether may have the formula HS(CH 2 S) n H, where n is between 2 and 7. The polymers may be cross-linked by heating with hexamethylene tetramine. Examples are given.

Abstract: 1,236,142. Recording and playback; associated working. BELL & HOWELL CO. 27 March, 1969 [10 June, 1968], No. 16229/69. Heading G5R. A sound recorder is preset to the recording mode by an operation which includes the connection of remote control means to the recorder. As shown, the insertion of a plug 46 presets a tape recorder 11 to the recording mode by energizing a relay 76, by-passing a pushbutton 77, and transfers control of the forwarddrive terminal 1 from a local push-button 43 to a remote switch 52 mounted on a cine-camera 93. In a modification (Fig. 4), the presetting is effected by the movement of a sliding door (175) to give access to a remote-control socket assembly (172). The relay 76 may be replaced by mechanical means (Figs. 2 and 3). On insertion or withdrawal of the plug 46, a protrusion 106 on a prong 102 briefly engages an extension 107 of a trip bar 62 to release any operated push-buttons on the recorder 11.

Title: A method of recovering paraffin wax from paraffin waxed paper
IPC: C10G73/42
Filed: 1959-05-14
Abstract: <PICT:0908710/III/1> A method for separating paraffin wax from paraffin-waxed paper without damaging the paper, comprises removing the wax from the paper by means of a stream of a solvent to give a substantially wax-free paper suitable as waste paper for pulping, conveying the wax-solution into a separator wherein the solvent is evaporated and the wax collected, the solvent being recondensed for re-use. The removal of the wax from the paper may take place in two or more successive steps, the solvent, e.g. trichloroethylene, employed for the later steps having already passed through paper of lowered wax content in earlier steps.  The method may be performed by filling extractor 4 with waxed paper, pumping trichloroethylene into the lower part of extractor 4, via preheater 3, by means of pump 2, the solution or emulsion of wax being carried to the upper portion of the extractor and thence to evaporator 6 within which the solvent evaporates and the wax is collected in the lower part to be removed via piping 10.  The solvent vapour is condensed in condensers 7, 8 prior to descending into tank 1 for recirculation.  Extractor 5 may also be filled with waxed paper, and the solution or emulsion issuing from extractor 4 being fed into the lower part of extractor 5.  After removal of the wax from the paper in extractor 4, extractor 4 is isolated, the paper removed therefrom, the extractor refilled with waxed paper, and the extractor returned into stream to receive the solution or emulsion issuing from extractor 5.
