ZWIETUSCH & CO., GES., 6, Salzufer, Charlottenburg, Berlin. Oct. 5, 1933, No. 27476. Convention date, Oct. 17, 1932. [Class 78 (iv)] [See also Groups XVIII and XXXII] Relates to means for transferring a goods container from a carrier on one path to or from a loading station or a carrier on another path, where the paths may be either terminal or closed and vertical or horizontal, and the carriers may be propelled by different means, as by rope conveyers or by individual motors. Each container is provided with an endless chain or other member which rolls or creeps from one carrier to the other or to the loading station during the transfer. As shown two containers 7, 7<a> are interchanged between a self-propelled carrier 1 running on horizontal rails 3 and an elevator 13 which is hoisted on the vertical guide rail 12 by a rope 11. Each container is surrounded by an endless chain 9, 9<a> which engages recesses 15, 15<a> in a supporting rail 6, 6<a> on the carrier 1 or elevator 13. Normally the chains are locked on the containers by levers 17, 17<a>. The rails 6, 6<a> are extended and provided with bevelled ends 22, 23. When the container 7 approaches a container 7<a> at rest, the bevelled ends 22, 23 of the rails 6, 6<a> engage the levers 17, 17<a> and unlock the chains, and the rails 6, 6<a> also engage bolts projecting from the chains. The carrier 2 then overruns the containers 7, 7<a>, the rail 6 leaves the chain 9 and picks up the chain 9<a>, and the chain 9 rolls on to the rail 6<a> while the chain 9<a> rolls off from rail 6a, the chains circulating round the containers during the transfer and the two containers moving at half the speed of the carrier 1.

Title: Improvements in ink ribbon mechanism
IPC: B41J33/40
Filed: 1928-09-28
Abstract: 298,156. Soc. Anon. Stenotype Grandjean. Oct, 4, 1927, [Convention date]. Ink-ribbon mechanism.-In ink-ribbon mechanism for stenographic and like machines, the feed mechanism comprises a worm-shaft which is rocked automatically to reverse the feed by means comprising a spring adapted to yield if the worm does not mesh fully with the worm-wheel when brought into engagement therewith; the inkribbon may pass over guides which are movable to change the colour-stripe and are associated with an indicator. In the mechanism shown in Figs. 1 and 7 the spools 34 are driven alternately by worms 37 on a shaft 38 journaled in a plate 45 which can rock on a vertical pivot 46. The shaft carries a loose collar 39 which is connected to the universal bar, and drives the shaft by means of a pawl or other one-way coupling. A spring blade 48 on the plate 45 engages a fork 49 in a plate 50 which can rock a pivot 50<a> and has a slot co-operating with a pin 51<a> on a plunger 51. A spring 60 engages the V-shaped top of the plate 50. The plunger is urged upwards by a spring 52 but is normally locked by a rod 58 carried by links 53 which are supported at the rear by rocking arms 57 and at the front by an arm 54 on a shaft 55, a spring 58a retaining the rod in engagement with a groove in the plunger. The shaft 55 is provided with arms 56 for engaging members 59 at the ends of the ink ribbon. In some cases the rod is carried by arms secured to the shaft 55. When the ink ribbon has been wound off either of the spools, the shaft 55 is rocked, the rod 58 is retracted, the spring 52 raises the plunger, the plates 50, 45 are rocked, and the worm shaft is rocked to disengage and engage the worms associated with the worm-wheels of the full and empty spools respectively. If the worm fails to engage fully with the worm-wheel, the spring 48 yields momentarily to permit of the worm working into engagement. When the reversing-movement is complete, the plunger is depressed manually to re-set the spring 52. The ink ribbon passes over vertically movable guide-rollers 31 which are raised to change the colour-stripe by depressing a plunger 61. The plunger has a pin engaging a slot in a rocking plate 64 which is connected by a link 66 to rocking arms 32 engaging the guide-rollers. The link actuates a rocking plate 69 provided with colour indicators 71, 72 which are visible alternately through a window.

Abstract: Polymers of conjugated dienes are made by polymerizing one or more such dienes in the presence of a zinc dialkyl and a catalyst comprising a divalent nickel or cobalt salt, which may be admixed with further catalyst components comprising an acidic metal halide and/or an organoaluminium compound.  Conjugated dienes specified are butadiene 2, 3-dimethylbutadiene-1, 3, 2-ethyl butadiene-1, 3, isoprene, 4-methyl hexadiene-1, 3, 2-methyl pentadiene -1, 3, 2-isopropyl butadiene -1, 3, octatriene -2, 4, 6, 2-amyl butadiene-1, 3, piperylene, and mixtures, e.g. butadiene and isoprene.  The divalent nickel or cobalt salt may be cobaltous bromide, fluoride, chloride, iodide, or nitrate, or similar nickelous salts.  Specified acidic metal halides are aluminium, gallium, indium, and zinc chlorides.  The organoaluminium compound may be aluminium triethyl, tri-isopropyl, tributyl, tri-isobutyl, isobutyl sesquihalide, diethyl hydride, or butyl dichloride.  The catalyst is formed by mixing the catalyst components in a hydrocarbon diluent.  For the polymerization the catalyst may be added as such or in combination with a solid carrier, or as a solution in a suitable solvent such as benzene, toluene, xylene, cyclohexane, or methyl cyclohexane.  The zinc dialkyl may be zinc dimethyl, zinc di-n-butyl, zinc di-isobutyl, zinc diamyl, zinc dihexyl, zinc didecyl, zinc diphenyl or zinc ditolyl or mixtures. The polymerization may be effected continuously and the reaction mixture is preferably agitated during the course of the reaction. The polymer is purified by conventional methods.  The polymers prepared by the process normally have a high content of the cis-1, 4-addition product, e.g. at least 90%.  The polymers may be used in the manufacture of tyres, belts, and tubes, and also in the preparation of impregnating and coating compositions.

Filed: 1921-10-24
Abstract: 174,572. Griscom-Russell Co., (Assignees of Sebald, L. E.). Jan. 27, 1921, CG'onvention date]. Generating by reduction of pressures of heated water.-In an apparatus for vaporizing liquids, particularly for evaporating brine or other impure water in producing distilled water for boilerfeed &c., a heating-agent such as steam or flue gases is passed through an inlet 2 on to the outside of a group of tubes 3 through which the liquid to be evaporated is forced by a pump 8. The heated liquid is sprayed through a pipe 11 above the surface of the liquid in the chamber 12. The vapour formed rises through baffles 13 to an outlet 14. A regulating-valve 4 on the pipe 11 retains sufficient pressure in the tubes 3 to prevent evaporation and consequent formation of scale therein. Residual liquid is withdrawn from the chamber 12 by a pipe 15 and recirculated by the pump 8. A continuous supply of fresh liquid and withdrawal of concentrated residual liquid in suitable proportions are maintained by pumps 20, 21 of different capacity mounted on the same shaft and operated by a motor 22. The proportions of liquid supplied and withdrawn may be varied by a by-pass 23, which enables liquid from the supply pump to pass to the withdrawal pump. The Specification as open to inspection under Sect. 91 (3) (a) describes also that the motor 22 may be controlled automaticall to maintain a definite level of liquid in the chamber 12. A separate float-controlled pump for the supply and separate regulator for withdrawing residual liquid may be used. This subject-matter does not appear in the Specification as accepted.

Filed: 1938-09-28
Abstract: 505,820. Wireless receiving circuits. HAZELTINE CORPORATION. Sept. 28, 1938, No. 28204. Convention date, Oct. 22, 1937. [Class 40 (v)] In a wireless receiver of the kind having motor-operated tuning controlled locally or remotely by means of push-buttons and wherein at least one amplifier stage is subject to A.V.C., the speed of rotation of the tuning motor is reduced in the neighbourhood of a signal of predetermined amplitude. The tuning motor M has a series field 23 and is controlled by push-buttons F, R giving forward and reverse running respectively. In series with the motor and winding 23, two coils 29, 30 of a saturabie reactor are connected across the A.C. supply 24, the central limb of the reactor having a coil 33 which carries the space currents of the valves 14, 16, 18 subject to A.V.C. voltages from 19, 20. With no signal, the current in 33 is large, the reactor is saturated and the reactance of coils 29, 30 is small; practically the full supply voltage is thus applied to motor M which runs at normal speed. As soon as a powerful station is approached the current through 33 falls sharply and the voltage applied to M is reduced with conse. quent reduction of speed. The receiver may be tuned rapidly through unwanted . stations by closing switch 40 to short-circuit coils 29, 30. In a modification, Fig. 2 (not shown), the valve space current operates a relay to insert or remove a resistance in the motor armature circuit and further . contacts on the relay mute the receiver during tuning.
