Title: Improvements in toy animals, automobiles and the like propelled by the rider
IPC: A63G15/00
Filed: 1933-02-18
Abstract: 400,478. Horse and like velocipedes. VESTERGAARD, H. V. C. and THOMSEN, S. W. C. E., 4, Raadhusstraede, Copenhagen. Feb. 18, 1933, No. 5110. [Classes 136 (ii) and 136 (iii).] In a toy animal or other vehicle propelled by bodily movement of the rider, the body 1 is supported on front and rear strip-metal springs 5, 3 so arranged and constructed that they are alternately flexed and straightened by backward and forward movement of the rider's body, the rear spring or spring 3 moving the rear wheel or wheels 17 forwardly when the rider leans backwards and moving the body 1 forwardly (the wheels 17 being prevented by clutches &c. from rotating backwards) when the rider leans forwards, whereby a forward galloping movement is obtained. In the form shown in Fig. 1, the front part 9 of the body is pivoted to the rear part by means of a pin 7, so that steering may be effected by means of handles 8. The rear spring 3 is bent downwardly and forwardly beneath the body 1, and is attached to a block 15 having bearing sleeves for the rear axle. The movement is assisted by one or more coil springs 18 interposed between the block 15 and the spring 3 or the legs 19. In the modification shown in Fig. 3, the body 1 is formed in one piece, and the front springs 5 are connected to a sleeve 20, which carries the axle of the front wheels 2 and is rotatable on a bolt 21, steering being effected by the action of the feet on the axle. The springs 5 are pivoted to the body 1 by means of a bolt 23, so that the body can swing vertically relatively to the springs, a tension spring 24 being interposed between the front and rear springs 5, 3. The pivotal movement between the body 1 and the springs 5 may be dispensed with by passing a bolt through holes 26 in the springs and body.

Title: Improvements in and relating to the treatment of cellulose with lye
IPC: C08B1/10
Filed: 1939-02-17
Abstract: 512,132. Treating cellulose webs with lye. MASCHINENFABRIK IMPERIAL GES., and SCHIEBER, W. Feb. 17, 1939, No. 5351. [Classes 2 (ii) and 15 (i)] Webs of cellulose are guided in countercurrent to a lye which is caused simultaneously to flow through them, for example, by applying suction once or several times on one side of the webs. The webs may be guided over rotary cylinders formed as revolving screens and provided with a vacuum. The webs whilst still in the lye, may also be pressed off directly upon the cylinders. In Fig. 2, the cellulose webs 1 pass over a filter drum 6 immersed in a lye container 3. Within the piped sector 24 the inside of the drum is covered. The webs pass under the impermeable band 26 where they are dried to a considerable extent, and the lye is then sucked through them only after they leave the band. By means of a partition 29 the container is subdivided so that lyes of different concentrations may be employed. Another pressure band 26 and a pressure roller 34 is provided at the rear of the partition 29. According to Fig. 3, the webs 8 and the lye 23 flow in counter-current direction and suction devices 30 and 31 are provided to suck the lye through the webs.

Title: A process for plasticising or masticating natural or synthetic rubber
Inventor: HOEPFNER KONRAD
IPC: C08K5/00
Filed: 1954-03-04
Abstract: A plasticizer for natural or synthetic rubber comprises an organic "electroneutral" salt obtained by reaction of equimolecular amounts of cationic surface-active and anionic surface-active compounds, or includes a mixture of equimolecular amounts of said cationic surface-active and anionic surface-active compounds.  The cationic surface-active compounds are preferably ammonium, sulphonium, or phosphonium compounds possessing at least one aliphatic, cyclo-aliphatic, aliphatic-aromatic, or cyclo aliphatic-aromatic radical with at least 6 and preferably not more than 20 carbon atoms, e.g. trimethyl-octyl ammonium chloride, trimethyl-dodecyl ammonium chloride, trimethyl-octadecyl ammonium metho sulphate, dimethyl-dioctadecyl ammonium chloride, dimethyl-dodecyl-benzyl ammonium chloride, dimethyl-cyclocyl-alkyl ammonium chlorides with alkyl radicals C10-C22 and/or corresponding mixtures thereof, dodecyl pyridinium chloride, and hexadecyl-pyridinium bisulphate.  The radicals can also contain oxygen, sulphur, or nitrogen.  The anionic surface-active compounds are preferably aliphatic, cycloaliphatic, aliphatic-aromatic or cycloaliphatic aromatic containing at leatst 6 and preferably not more than 20 carbon atoms and at least one salt forming group, e.g. alkyl sulphates or sulphonates, alkyl-benzyl sulphonates, salts of sulphonated oils and fats, of dialkyl and/or dialkyl-aryl disulphonimides or N-acyl sulphonamides, of fatty acids and of the condensation products of high molecular weight carboxylic acids or sulphonic acid halides with proteins.  Among the examples of such anion-active compounds quoted are the water soluble salts of wax acids, naphthenic acids, resin acids, octyl-hydroxy acetic acid, hexadecyl-mercapto acetic acid C-alkyl cresoxy acetic acids, dodecyl or oleyl sulphuric acid ester, the sulphuric acid esters of ethylene glycol mono-octyl ether, the mono or di-sulphuric acid ester of glycol-mono-stearic acid ester, the phosphoric acid ester of decanediol-mono-acetate, the o -butyl-ether or decyl sulphuric acid ester, the o -hexyl thio ether of octyl thio suphuric acid ester and the mixture of isomeric 2-isoalkyl-cresoxy-benzoic acid-sulphonic acids 5, with alkyl radicals of from 5 to 11 atoms.  The amounts of plasticizer employed is 0.5 to 30 per cent of the weight of the natural or synthetic rubber.  In an example 20 parts by weight of the "electroneutral" salt obtained from equimolecular amounts of dimethyl-cyclohexyl-dodecyl ammonium chloride and dedeyl sodium sulphate and 10 parts dioctyl phthalate are compounded with 130 parts smoked sheets.

Abstract: <PICT:0811366/III/1> <PICT:0811366/III/2> <PICT:0811366/III/3> In the fluidizing process, the solid particles are prevented from falling through the support by horizontal baffles mounted above and/or below the support to form slots which have a width 1 1/2 to 20 times the aperture of a B.S. sieve on which 90 per cent of the particles forming the bed are retained.  For example, with particles ranging from 1/16 inch of which 90 per cent is retained on 100 mesh B.S. sieve of aperture size 0.006 inch, a slot width of 0.03 to 0.09 inch may be used.  The horizontal strips of the support 1, Fig. 1, and baffles 4 forming slots 8, may be of heat-resisting steel or of low alloy. Alternatively the strips and baffles may be combined in the form of crank-shaped sections, Figs. 5 and 6.  A fine control over the flow of gas is obtained by partly or completely blocking some of the slots.  Preferably the total cross-sectional area of the slots is less than 1/20 that of the whole support.
