Abstract: 135,817. Elektro-Osmose Akt.-Ges. (Graf Schwerin Ges.). Oct. 20, 1917. [Convention date]. Electric endosmose.-In the dehydration of vegetable, animal, or mineral substances, for instance clay or peat, the water separated is used again in preparing fresh material for the treatment. The material may be mixed or ground with the liquid, or may be washed from its natural bed thereby, as in hydraulic mining. The water may contain sufficient electrolyte to bring the substance into the " sol '' condition, or a little more electrolyte may be added. In the treatment of clay, the water contains caustic soda, if this substance or water-glass has been added to the previous charge, while in the case of peat it may also contain some ammonia.

Abstract: 834,629. Surgical optical apparatus. ZEISSSTIFTUNG C., [trading as ZEISS, C., [Firm of]], April 2, 1958 [April 9, 1957], No. 10536/58. Class 81 (2). Apparatus for producing coagulation in the eye, for use in cases of detached retina, comprises a condenser, producing a beam of parallel light rays from a high-intensity lamp, and a mirror for directing the beam into the eye, all these parts being mounted on a common adjustable carrier. In the form described, the carrier is formed by a tube 3, Fig. 1, mounted in a gimbal ring 41, which is itself carried on parallel links movable about a vertical axis on a laterally placed pillar 50, so as to allow axial movement of the tube. During such axial movement correct directional positioning is ensured by a pin 49 engaging a cam slot in a fixed plate. The entire assembly is balanced about the horizontal pivots 42 by an adjustable counter weight 9. The lamp 4, which is preferably a high-intensity arc lamp is mounted on an adjustable carrier ring 56. Within the tube 3, Fig. 2, is the condenser 12, which gives intense, uniform illumination of a diaphragm 13, and a focusing lens 14 which projects a parallel beam of rays to a mirror 15 and thence into the eye 16, where the natural lens 17 focuses it on the retina. During preparatory adjustment a screen 11 is interposed in the beam, and this has a series of small circularly arranged holes 18, and also a slide 10 cuts off the light from the central part of the lamp. In addition the eye is observed by the surgeon through an aperture 19 in the mirror 15. This aperture is, however, partially obscured by a grey filter 21 during the actual treatment.

Title: Improvements in the preparation of compositions of natural rubber
IPC: C08C1/14
Filed: 1955-04-14
Abstract: Coagula in the form of coherent sheets which dry quickly are prepared from aqueous dispersions of natural rubber and reinforcing fillers by controlled temperature heat treatment during coagulation and during machining of the coagula between rolls.  The coagulation may be effected by the addition of a heated coagulant, or by adding a coagulant to a heated aqueous latex-filler dispersion, or by heating both coagulant and dispersion before or after admixture.  Heat is applied during machining by heating the rolls and/or by spraying the coagulum with a stream of hot water.  The filler may consist of lignin, carbon black, cyclized rubber, finely-divided silica, a silicate, clay, or a synthetic resin such as polymethyl methacrylate or polystyrene.  In one example, a mixture of latex and a solution of lignin in caustic soda, comprising equal weights of rubber and lignin, is poured continuously into boric acid at 95 DEG  to 100 DEG C. and live steam is blown through the mixture during the mixing. The co-precipitate coalesces into a gel-like coagulum, which is washed in hot water and sheeted on heated rolls.

Abstract: 1,090,799. Photo-electric systems. INTERNATIONAL BUSINESS MACHINES CORPORATION. March 16, 1965 [March 16, 1964], No. 10970/65. Heading G1A. An electro -optical system for measuring and signalling transmissivity comprises means to scan a record to measure its transmissivity point by point and display the measurement on a cathode ray tube, and a mask modulating the light in at least two different characteristic ways in dependence on the transmissivity value. The transmissivity contours of the object 11 are determined by scanning it with a flying spot scanner 10 and receiving the light transmitted with a photo-cell 13. The output of photo-cell 13 is applied to the Y plates of a cathode ray tube 14 synchronized in the X deflection with scanner 10. A mask 15 allows light to pass to a photo-cell 17 when the spot on tube 14 has a given Y deflection corresponding to a predetermined transmissivity. The resulting pulses are used to brighten the spot on a cathode ray tube 18 which is synchronized in X and Y deflection with the scanner 10 so that the contour corresponding to the predetermined transmissivity. If it is desired to transmit the transmissivity value by pulse width or pulse frequency modulation rather than merely determine where it has a predetermined value, the mask 15 is replaced by other masks, Figs. 5 and 6 (not shown).

Abstract: 875,177. Continuous sterilization of liquids in bottles &c. SIEBOLS, P. April 2, 1959 [April 2, 1958], No. 11189/59. Class 49. [Also in Group XXX] In apparatus for the continuous sterilization of articles, such as bottles of milk-coffee mixture or chocolate-milk of high fat content, beer or lemonade, consisting of consecutive chambers I to X (Fig. 1) forming an oblong tunnel which is divided up internally into a number of compartments separated by partitions 1, wherein heating, sterilization and cooling of the articles successively take place, the articles are advanced stepwise in a number of axially rotating containers 3 from one compartment into the succeeding one through opening and closing hatches 2 in the partitions and a head-over rotation is imparted to the containers about their axes in at least some of the compartments. The head-over rotation is effected by the rotation of shafts 5 at the ends of the containers in semi-circular bearings 6, through a gear 14 on the shaft cooperating with a second gear 15 driven through a worm from a single shaft 17; the rates of rotation of the containers in the various compartments is varied by suitable selection of the ratios of the worms. Alternatively the rotation may be obtained by employing friction wheels, chain-sprocket wheels or V-belts. The containers 3 are advanced by the movement of beams 18 on which bearings 21, for receiving the shafts 5 of the containers, are mounted. The beams 18 are lifted by the raising of beams 20 through a mechanism 22, a forward movement of the beams 18 on rails 24 is urged by hydraulic or pneumatic cylinders 23, the stroke of which accurately corresponds with the pitch of the bearings 6, and the shafts are then lowered into the bearings 6 by lowering of the beams 20. The lifting and conveying mechanism is arranged to actuate the opening and closing of the hatches 2. Where the shafts of the containers are supported between the double side walls 26, 27 of the compartments (as shown in Fig. 5), the longitudinal slot needed along the inner wall 26 may be encased by shiftable plates.
