Patent GB-392704-A (GB)
Abstract: 392,704. Indiarubber and like springs. SCHIEFERSTEIN, G. H., 105, Alt-Moabit, Berlin. May 14, 1932, No. 7562. Convention date, March 14, 1931. [Class 108 (iii).] In mechanical " tunable oscillatory units of the kind comprising an elastically constrained mass adapted to be energized at substantially resonant speed through a " loose coupling," such as a weak spring or pendular mass, fluctuations of amplitude are reduced by using solid rubber or like non-metallic elastic members interposed between rigid members which co-operate to increase the natural frequency of the unit with increase of amplitude, and vice versa. The elastic members may themselves constitute the mass-constraining means, or may form auxiliary buffers to come into action above a predetermined amplitude only, the main constraining-means being either rubber or ordinary springs. Main rubber springs 3, Fig. 2, are precompressed between yokes 6 on the mass 1 and yokes 2 on a driving-frame, which carries also adjustable yokes 5 adapted to contact with auxiliary rubber buffers 4 on the yokes 6 just prior to attainment of resonant speed. The abutments 5 or, as shown, the buffers 4 preferably present spherical, paraboloidal, &c. surfaces to the coacting members, in order to graduate the change in stiffness of the elastic constraint. In a modification, the buffers 4 are carried on the outer faces of the yokes 2 and coact with adjustable abutments on the mass 1. Fig. 4 shows a further modification, in which an abutment 5 and adjustable yokes 6 are carried by the mass 1 and the buffers 4 are mounted on adjustable driving-yokes 2. The rubber springs may be built up of units comprising rubber rings 10, Fig. 6, vulcanized, with or without interposed hard-rubber layers, to perforated metal discs 9, which are peripherically connected to those of adjacent units by bolts, rivets, or enveloping hinged clips 11 having clamping-screws 13. Where the variable-stiffness effect is to be produced by restricting radial expansion of the rubber springs above a predetermined deflection, internal bushes 14 and the clips 11 are shaped to fulfil this condition, as shown. Alternatively, the outer edges of the discs 9 may have coned extensions overlying the rings 10. Fig. 9 shows a centrally-perforated rectangular rubber block 10 confined between perpendicularlydisposed metal bands 15, 16, and Fig. 10, iron plates carrying a ring 10 and two pairs of concentric auxiliary buffer rings 18, 19 adapted to contact successively. All the above constructions facilitate dissipation of the heat of internal friction. The longitudinal axis of the rubber compression springs is preferably coincident with the path of movement of the centre of gravity of the oscillatory unit, or, when several elastic systems are employed, their axes are preferably coplanar and parallel therewith. Specification 223,852, [Class 108 (iii), Springs &c.], describing means for obtaining a similar effect with steel and pneumatic springs, is referred to.

Abstract: 1,153,337. Carbon electrodes. DEUTSCHE AKADEMIE DER WISSENSCHAFTEN ZU BERLIN. 6 Sept., 1966, No. 39777/66. Heading H1B. A carbon electrode for galvanic elements consists of a hydrophobic carbon body provided with a hydrophilic covering layer, the carbon body consisting of activated carbon, optionally in admixture with graphite, and a hydrophobic binding agent and the covering layer consisting of activated carbon, optionally in admixture with graphite, a catalyst which increases the electrochemical loading capacity of the finished electrode and/or promotes the thermal decomposition of the binder and a hydrophobic binding agent and decomposition products thereof, the amount of binding agent in the covering layer being less than the amount of binding agent in the carbon body. As current lead-off and for increasing the mechanical stability, a metal mesh or cross-piece is provided within the covering layer or in the immediate vicinity thereof within the hydrophobic part of the carbon body. The covering layer may also contain a wetting agent for the improvement of the hydrophilic properties thereof. The electrodes may be prepared by the partial decomposition of the binding and hydrophobing agent with the simultaneous separation of catalyst. This may be achieved by forming a pressed body of activated or unactivated carbon powder and a hydrophobic binding agent at 20‹ to 400‹ C., superficially impregnating or spraying the pressed body with a solution of a salt of a catalyst and heating to separate the catalyst and for the decomposition of the binding agent. The binding and hydrophobing agent may be natural rubber, polytetrafluoroethylene, polystyrene, polyethylene, a fluorine-carbon copolymer or polyethylene wax. In a typical example, tempered activated carbon and an aqueous dispersion of polytetrafluoroethylene are mixed, dried and together with a lead-off are coldpressed to form a carbon body, which is partially immersed in a silver nitrate solution and then heated at 390‹ C. to separate out the catalyst and to provide a hydrophilic covering layer.

Title: Antibiotic funginon and a process for the production thereof
Inventor: SAWADA JIRO
Filed: 1964-09-30
Abstract: A new antibiotic funginon, effective against gram-positive and -negative microorganisms and ascites tumor is produced by cultivating Aspergillus clavatus TPR-3202 (ATCC. 15550) or a funginon-producing mutant thereof in an aqueous nutrient medium containing assimilable C and N sources and inorganic substances. Funginon is recovered from the medium by adding diatomaceous earth, filtering, adding active C to the filtrate and then extracting the absobed funginon from the active C with 80% aqueous acetone, ethylacetate and ether after distillation at each stage, absorbing funginon on to a column of chromatographic active alumina, followed by elution with ethylacetate, which is distilled off, leaving a residual of pure funginon.  Funginon, a yellow oily matter, is soluble in water, methanol, ethanol, acetone, ethyl acetate, butyl acetate, glacial acetic acid, ether, pyridine and dioxane, slightly soluble in chloroform and benzene, and insoluble in carbon tetrachloride, petroleum ether and hexane; it has the elemental analysis: C 53.34%, H 5.33%, O 41.31% (by difference), a mol. weight of 144 and optical rotation [a ]20D= +43.55 DEG  (in water); it gives a brownish-black colour but no silver mirror by Tollens test, positive nitro-prusside, Molisch, Benedict, Nylander, diazo, Fehling and Nessler tests and negative FeCl3 and Biuret tests, a maximum U.V. absorption of E1% = 725 at 273-263 mm  1cm in methanol and I.R. absorption maxima when suspended in a KBr disc at 3380, 2930, 1775, 1750, 1680, 1450, 1403, 1375, 1250, 1220, 1173, 1075, 1035, 1005, 877, 829 and 785 cm-1. Funginon is stable at pH 3.0-7.0 but is unstable above pH 7.5 and on heating.

Title: Nuclear power reactor with rod-shaped fuel elements
Inventor: SCHMIEDEL FRIEDRICH
IPC: G21C3/04
Filed: 1962-10-22
Abstract: 960,678. Reactors. BETEILIGUNGS-UND PATENTVERWALTUNGSGESELLSCHAFT. Oct. 22, 1962, No. 39943/62. Heading G6C. A nuclear reactor with no bottom grid has horizontally rod shaped fuel elements the ends of which are connected to longitudinal members to form a number of ladder-like groups in which the fuel elements form the rungs of the ladders. The invention is applicable to boiling water and gas cooled reactors and provides a single zone within the reactor in which superheating takes place. The fuel may be metallic or ceramic compounds of circular or elliptical cross-section. A further feature of all the embodiments described is that one of the longitudinal members of each "ladder" is movable in a direction parallel to the fuel element axes in order to accommodate thermal expansion. The water cooled reactor shown in Fig. 7 comprises two heating zones, the first heating the water, which may be heavy water acting as coolant, moderator and shield, and the second superheating the resultant steam. Each ladder-like fuel assembly is immersed in the liquid coolant, and the steam thereby generated accumulates above the water level in the reactor before passing into the first hollow longitudinal member 6 of the fuel assemblies From the member 6 the steam passes through the interiors of the hollow fuel elements 5, out through the second longitudinal member 7 and into a steam accumulator 8. Superheated steam passes from the accumulator either to a heat exchanger or direct to a turbine. The superheating coolant circuit may be modified by placing a divider at approximately the mid point of the longitudinal member 6, such that the entire steam flow passes from left to right in the upper half of the "ladder", and from right to left in the lower half. The upper end of the longitudinal member 7 is closed, and the steam accumulator is connected to the lower end of the member 6. In a modified form of boiling water reactor, solid fuel elements are used, there being no circulation of coolant within the "ladder". In this case, the superheating takes place in a zone above the water level into which the "ladder" ends project. The gas cooled reactor shown in Fig. 11 utilizes a solid fuel element surrounded by two spaced apart concentric graphite tubes (Figs. 8, 9, not shown). Provision is made for circulating a scavenging gas (entirely independent of the coolant circuit) through the graphite annulus surrounding each fuel element via inlet and outlet connections made to the two longitudinal members 24, 25. Gas . enters the reactor through an annulus 29 and passes dpward, cooling the reflector 28. The thus preheated gas then passes down through the core and out through a pipe 32. An advantageous feature of both the boiling water and gas cooled reactors described is that the "ladder" construction of the fuel assemblies obviates the need for a bottom grid plate. The weight of fuel is supported through the longitudinal members on an annular ring positioned in the bottom of the reactor.

Abstract: 1,131,649. Separating minerals by froth flotation. GOSGORKHIMPROEKT. 7 Sept., 1966, No. 39985/66. Heading B2H. In a process for separating mineral particles by froth flotation a pulp of the particles is caused to froth by aeration, the frothed pulp is fed on to the surface of an aerated fluid so that it spreads in a layer over the whole surface of the fluid, an ascending flow is caused in the aerated fluid in the region where the frothed pulp is fed on to it, and a flow is caused, at the surface of the aerated fluid at which separation occurs, in a direction from the pulp feed-in region to a location at which the required separated fraction of the mineral particles is discharged, the intensity of aeration of the fluid being decreased in the direction of flow at the surface of the fluid. In the apparatus shown in Fig. 2, the fluid is contained in a tank I and is aerated by air blown through two rows of perforated pipes 2 connected to collectors 3, 4, the collector 3 having three sections each of which is connected to a source of compressed air in such a manner that more air is fed into the tank at the pulp feed-in region than at the froth product discharge region. Reagentconditioned pulp is fed through a pipe 9 and spreads into a thin layer on to inclined decks 8 arranged in cascade. A spreader 11 distributes the pulp evenly into two launders 7 in which air and liquid are added to the pulp by means of perforated pipes 12 and nozzles 13 respectively The frothed pulp spills over the upper curved portions of the walls 14 of the launders on to the surface of the aerated liquid. The non-uniform delivery of air in the tank I gives rise to a vertical upward flow of liquid and air bubbles in the pulp feed-in zone where the bubbles concentrate, this upward flow being changed to a horizontal flow by the upper curved portion of the launder walls 14 thus carrying the froth and the desired separated particles contained therein towards an over flow lip at the tank periphery. The unwanted particles sink towards the bottom of the tank and are removed through an automatically operated valve 5. In a modification, Fig. 3, the fluid is aerated by means of air which is fed with water as a mixture through ejectors 15 which direct the mixture against the launder walls 14 so as to create the concentration of air bubble in the pulp feed-in zone and the horizontal flow in the surface of the fluid. In a further modification, Fig. 4 (not shown), aeration of the fluid is by air blown through a row of perforated pipes and through nozzles arranged in the sides of the tank above the level of .perforated pipes. In a still further modification, the apparatus may be one-sided and have only one launder 7 in which case the spreader 11 is dispensed with. Instead of a valve 5, a screw or a conveyor may be provided.

A collapsed carton is erected by gripping and continuously advancing the bottom wall 12b (Fig. 2) along a feed path and gripping the top wall 12t such that it moves at a slower rate than the bottom wall. As described, a collapsed carton 12 (Fig. 1a, not shown) from a stack (10) is lowered by a suction gripper (36) on to horizontal supports 38, along which it is moved by pusher members 50 pivotally attached to an endless chain 42. After passing beneath a depressing. cam 56, the carton 12 is moved forward by engaging its bottom wall 12b with a suction cup 80 attached to a slide block 76 which is in turn pivotally connected to a moving chain 72. A further suction cup 96 is cammed downwards to engage the fop wall 12t of the carton, which is then moved upwards as the bottom wall 126 is advanced thereby erecting the carton. As the bottom of the carton 12b is moved further forward, the sides 12l and 12r are bent in the reverse direction (Fig. 11d, not shown), whereupon the suction on the top wall 12t is released and the carton flattened beneath the roller (116) (Fig. 1d, not shown). The erected carton may then be moved by the pusher members 50 to a filling station (Fig. 1f, not shown). The bottom wall 12b may be held by an additional suction gripper (122) (Fig. 12, not shown), which is moved forward against the action of a spring (130), which returns the gripper to its original position when the suction is removed. The vacuum is applied to the suction cup 80 by passing the slide block 76 over a manifold 78 (Fig. 8, not shown), which has openings (152) communicating witha passage (170) in the slide block and openings 168 in a vacuum tube 150 rotating within the manifold. Alternatively, the tube 150 may be replaced by a rotating rod (208) (Fig. 14, not shown) having a-continuous groove (210) on its surface.
