IPC: F23L17/10
Filed: 1923-02-07
Abstract: 213,727. Mottershall, W. H. Feb. 7, 1923. Aspirating-apparatus, ejector; regulating or controlling action.-In a wind-directed cowl fitted with an ejector tube for creating up-draught by the action of the wind, inter-connected means are provided for varying, according to wind velocity, the area of the inlet and outlet ends of the tube and the length of the chamber into which the tube delivers. As shown, the cowl comprises a T-shaped bead 7 rotatably mounted on ball bearings on a fixed shaft 1, the ejector tube 21 being supported by a spindle 18 which is secured to a cross-web 17 and provided with a nut 23 to prevent, by engagement with a member 47, displacement of the cowl. A rod 29, having its forward end slidable in a sleeve 30 mounted on a bracket 31, extends through the horizontal portion 20 and carries a fixed inner conical tube 40 and a slidable intermediate cone 38 supported by a web 39 between which and the web 43 is a spring 42. A cone-shaped member 35, arranged in the outlet end of the tube 21, is fixed to the rod 29 which extends through a tubular bearing 32 carried by the wind-vane 16 and terminates in an eye 33 through which passes a bent rod 34. Fig. 3. secured to a sleeve 24 slidably mounted on rollers 26 attached to the rear end of the part 20. Slots 27, 28 are formed in the vane 16 to allow movement of the sleeve 24. Fig. 1 shows the parts in normal position; on the velocity of the wind increasing, the cone 40 telescopes into the cone 38 carrying with it the rod 29 and thus moving the member 35 and the sleeve 24 rearwardly. Further increase in wind velocity causes engagement of the cone 40 with the web 39 and consequent rearward movement of the cone 38 to reduce further the area of the inlet of the tube 21. When the wind drops, springs 42, 44 return the parts to normal position.

Title: Animal foodstuffs
IPC: A23K20/168
Filed: 1957-02-04
Abstract: A xylene isomer is obtained from a petroleum naphtha fraction by passing the naphtha together with a recycle gas containing normally gaseous constituents and a recycle liquid stream over a platinum-containing catalyst at 450-550 DEG  C. and 100-800 p.s.i.g., separating a gas stream from the product for the recycle gas stream and distilling the liquid product to obtain a narrow-boiling, xylene-containing fraction from which the desired xylene isomer is separated, a fraction containing at least part of the remaining xylene isomers being recycled as the recycle liquid stream.  The naphtha feed preferably has an initial boiling-point in the range 50-100 DEG  C. and a final boiling-point in the range 170-200 DEG  C. and contains by weight 35-70 per cent paraffins, 20-50 per cent naphthenes and 7-25 per cent aromatics.  It may be passed over the catalyst at a space velocity of 1-10 vol./vol./hr., with a gas recycle rate of 8000-12,000 standard cubic feet per barrel of feed and a liquid stream recycle rate of 5-25 per cent by weight based on fresh feed.  The catalyst may be 0.1-1 per cent platinum on alumina with 0.1-8 per cent of halogen.  The xylene-containing fraction recovered from the product may have a boiling range within the range of 120-145 DEG  C. The separation of the xylene isomers is performed conventionally, e.g. as described in Specification 625,570.  If para-xylene is desired this is preferably separated by fractional crystallization with carbon tetrachloride, as in Specification 677,368.ALSO:Animal feeds contain, as a growth-promoting supplement, a heteroauxine, i.e., a compound which has specific activity on the growth and multiplication of plant cells and is of molecular structure comprising an aromatic ring and a side chain with a carboxyl group or group easily convertible to the carboxyl group. The compounds are exemplified by phenyl-phenoxy-, 2-methyl-4-chlorophenoxy-, 2, 4-dichlorophenoxy-, b 1-indolyl-and a -naphthyl-acetic acids and their salts. The compound may form 0,0005-0,005 per cent. of the feed dry weight.

Abstract: 213,074. Schulz, P., and Jakowitsch, J. Feb. 14, 1923. Chucks.- A bevel-closing chuck has a slow differential closing movement and a quick direct opening movement. Wedge jaws 3 are moved axially by a sliding ring 4, prevented from rotating by a pin 20 and engaged by a nut 5 having external teeth meshing with an internally toothed ring 7. This ring has a slightly larger number of teeth than the nut and is freely rotatable in an eccentric rib 13 carried by a sleeve 12, the rib fitting between a flange 15 and a projection 16 on the ring in order to communicate axial movement from the sleeve to the ring. In operation, the jaws are closed by sliding the ring 7 to engage a projection 11 on the ring with a projection 9 on the chuck body and holding the sleeve 12 against rotation, when the ring will describe an eccentric movement relatively to the nut and will slowlv rotate the latter about the ring 4. The jaws are opened by sliding the sleeve to the left, as seen in Fig. 1, and so engaging a slot 14 on the sleeve with the projection 16 cn the ring, when retardation of the sleeve will retard rotation of the nut relatively to the ring 4. A pin 18 limits the axial motion of the sleeve. Screwing die-heads; taps.-The chuck may be used for cutting internal or external screw threads by forming the jaws as dies, the pressure of the jaws being directed inwardly or outwardly as the case may be.
