Abstract: 484,787. Drying stockings. SCHUSTER, F. Nov. 20, 1937, No. 32023. Convention date, Nov. 27, 1936. [Classes 34 (i) and 34 (ii)] Stockings are inserted in a drying chamber by supporting them on upright supports 2 on which they are not stretched but fit sufficiently loosely to be capable of a fluttering motion. The stockings may be passed through the chamber by mounting the supports on conveying chains, pairs of supports being preferably mounted together. The supports are guided by extensions 5 resting on a guideway 6. The supports consist of flat tapered strips of sheetmetal or of similar strips 2a, Fig. 9, bent along their longitudinal middle axes and mounted so that the concave sides of continuous supports are directed towards each other. Pairs of flat stocking forms 7, Fig. 12, may be interposed between pairs of supports 2 on the same endless conveyer, so that after passing through the drying chamber 9a on the supports 2 the stockings may be removed therefrom at the point A and stretched over the forms 7 for subsequent moistening at 8 and pressing between rollers 9. Wet stockings are then placed on the supports 2 at the point C and move in common with the stockings on the forms through the drying chamber, the latter being finally removed at the point A.

Abstract: 1,098,205. Vending apparatus. TATEISI ELECTRONICS CO. July 18, 1966 [July 29, 1965], No. 32229/66. Heading G4V. A vending machine adapted to receive a tape cassette 20, is freed for operation on receiving an appropriate length of tape from the cassette, the tape having credit markings along its length or a given credit value per unit length. The tape carries magnetic or shaded marks or perforations. The free end of the tape is held by felt pads 24 and rests on a shoulder 25 of the cassette. A feed roller 34 is driven by a motor 53 when a switch 39 is closed by the cassette and one of the article or service selecting buttons 41a-41e is depressed. Operation of a button 41a-41e pulses a counter 43 to apply an input to the AND gate 45a-45e corresponding to the price of the article or service. A counter 44 is stepped by the passage of the tape past a detector 37 to apply inputs to the AND gates 45a-45e in turn. On receiving inputs from both counters, an AND gate fires to change over flip-flop 51 and stop motor 53. In addition the article or service release means 47 is operated and the cutting means 38 energized to sever the tape from the reel. Alternatively, rotation of a pointer over a fixed price scale by a customer feeds the tape into the vending machine.

Title: Improvements in apparatus for removing the separated solid matter from strainers for liquids
IPC: E02B8/02
Filed: 1929-10-24
Abstract: 335,767. Dorr Go. Nov. 9, 1928, [Convention date]. Strainers comprising grids or gratings. -In apparatus of the type in which a rake or scraper is moved along a strainer in one direction to remove accumulated material therefrom and is returned at a distance, from the straining surface, the scraper is mounted on a jointed frame supported on an axis and is actuated by driving means moving a joint on the frame in a closed path similar to the path of the scraper. A rake 12 for cleaning a strainer 11 is carried by arms 15 which form one side of a parallelogram frame, the other sides of which are formed respectively by arms 13 pivoted on a fixed axis 26, arms 14 similarly pivoted, and beams 32 connecting the arms 14, 15. A shaft 16, which has bearings in the beams 32, is provided at its ends with guide rollers, which engage oval guide races rigidly supported on bases 51, and with pinions 17 which mesh with racks 18. The guide races and racks are similar in shape to the path A which the rake should take and are a.t the same inclination. The rake is therefore caused to move as required by rotation of the shaft 16. This shaft is turned by belt and worm gearing from an electric motor carried by the beams 32. An overload on the rake, due to obstruction, increases the end thrust on the worm shaft which is caused to move laterally against a spring and this motion operates switches which cut off the current from the motor and give an alarm respectively. The rake is cleared by a scraper 21 carried by pivoted arms 30, the matter removed falling on to an apron 20, carried on a pivoted frame, and being directed therefrom to a drainage platform 27 or suitable conveying apparatus. The apron 20 is pushed up by the rake but is caused by a counterweight 29 to fall back underneath it to receive the matter pushed by the scraper 21 off the teeth of the rake.

A further valve 3c is located downstream of fan 8, as shown, or between valve 3b and fan 8, and enables fan 8 or fan 1 to induce a flow of air through the filter to outlet 11, valves 3a and 3b being then in positions 17, 18, to remove disinfectant from the filter before it is restored to filtering with valves in positions 12, 13 and 16. A downstream filter 5 removes any residual disinfectant.

Title: Improved process for effecting chemical reactions of olefinic hydrocarbons
IPC: C07C2/18
Filed: 1935-10-17
Abstract: In effecting reactions of olefines with the use of a solid phosphoric acid catalyst, steam or aqueous fluid is added in such quantity that the vapour pressure of the acid is balanced by the partial pressure of the steam so that loss of water is prevented. Single olefines such as propene or isobutene, and particularly gaseous olefine mixtures such as cracking gas may be polymerized to liquids by passage at about 205--260 DEG  C., and 5--20 atm. or more over a catalyst approaching the pyro- or orthoacid in composition made by calcining a mixture of the ortho- or pyro-acid with a solid adsorbent under controlled temperature conditions as described in Specification 463,272, [Group III].  Steam equivalent to about 1--6 per cent by volume of the gas mixture is added.  With cracking gases, the products are dimers and some trimers of propene, butenes, pentenes, and hexenes.  These are primarily mono-olefinic, branched-chain polymers and are employed as constituents of motor fuels, giving a high anti-knock value on addition of such compounds as lead tetraethyl.  On hydrogenation, paraffins of only slightly lower anti-knock rating are obtained. Other reactions referred to are the alkylation of aromatic hydrocarbons or amines or phenols, and the treatment of gasoline-like hydrocarbon mixtures with olefines.  In an example, gas from the stabilizer of a cracking plant containing 30 per cent by volume of propene and higher olefines is passed in parallel through towers containing the freshly prepared catalyst at 232 DEG  C. and 6,8 atm., without steam, and with the addition of 1, 3 and 6 per cent respectively of steam, figures for the percentage conversion being given.ALSO:In effecting reactions of olefines with the use of a solid phosphoric acid catalyst, steam or aqueous fluid is added in such quantity that the vapour pressure of the acid is balanced by the partial pressure of the steam so that loss of water is prevented.
