Abstract: IMPROVED HYDROGEN VENT ASSEMBLY   ABSTRACT OF THE DISCLOSURE      An improved three-piece polymeric hydrogen vent assembly for use on chlor-alkali diaphragm cells comprises an elongated tube contain-ing a standpipe and an inverted cup which separates the standpipe from the tube.  The cup has a plurality of openings in its base portion and a manometer fitting in its top.  The entire three-piece assembly is fabricated from a polymeric material, preferably polypro-pylene, and can be conveniently molded in a one-piece unit.  Each individual component of the assembly can be separately cut from the single molded unit and assembled.     The hydrogen vent assembly is primarily useful as a replacement for existing steel components and has the advantages of being less corrosive than carbon steel, easier to install, and safer in opera-tion since it has a reduced risk of overflow during cell start-up.

Abstract: ABSTRACT OF THE DISCLOSURE           A method of transformation of animal blood and its fractions into valuable products, such as poultry blood into a fodder product,  the mushy liquid of blood cells into pharmaceutical or cosmetic products, and the whole blood and plasma of any animal blood into fodder and food products of high nutritious and taste qualities.  The method according to the invention comprises the basic step of stabilizing the blood or its fraction with at least one compound capable of binding calcium ions naturally appearing in the blood and subsequently subjecting the so stabilized blood a fractions to a thermal treatment.  This method is characterized in that it comprises the additional steps of:   adding to the blood or its fraction at least one organic or inorganic compound of calcium in the amount of 0.009-0.018 mole/dm3, such an amount corresponding to an equivalent amount of 0.1-0.2% by weight of calcium chloride;  adding to the blood or its fraction at least one salt of sodium, potassium, or calcium in the amount of 0.085-0.43 mole/dm3, such an amount corresponding to an equivalent amount 0.5-2.5% by weight of sodium chloride;  leaving alone the blood or its fractions with the above additions for a period of time sufficient to allow solidification into a product having the same volume as  the  total volume of  the starting compounds;   and thermally hardening the so obtained product.   It is preferable to enrich the nutritious and taste values of the obtained product by adding therein neutral or acid protein-carbohydrate substances, vitamins, microelements, amino acids, taste and aromatic substances.

Abstract: ABSTRACT         A method for applying an electric charge in ink jet printers of the so-called continuous kind, in which electrically conductive ink or like medium is forced in the form of a jet (3) from a container through a nozzle (1) or the like and is caused to form droplets (4), which are electrically charged and which are caused to pass deflecting electrodes (6) to which a voltage is applied and are caused to travel along a movement path dependent, inter alia, upon the electric charge, thereby to provide a pre-determined transcript or the like on a printing sheet (5) or corresponding material.        The method according to the invention is particu-larly characterized in that disturbances of a given kind are generated in a known manner by means of a piezo-electric crystal (8) and are caused to act upon the jet (3) in a manner to cause the jet to disintegrate into droplets (4) in a pre-determined fashion, and in that the ink is electrically charged in the nozzle (1) by varying the voltage applied while taking into account the pre-determined frequency at which droplets are separated, whereby practically each droplet (4) is given an individual, pre-determined charge lying in relation with the level of voltage applied on conjunction with the separation of the droplets (4).        The invention also relates to an arrangement for carrying out the method.          Figure 1 for publication.

Abstract: ABSTRACT       Olefins such as propylene can be oxidized directly to .alpha.,.beta.-unsaturated carboxylic acids such as acrylic acid with air or oxygen in an aqueous medium under moderate reaction conditions employing a novel palladium metal catalyst which has been activated by contacting it with propylene at temperatures of from about 60 to 150°C for about 10 to 120 minutes.  Similarly, isobutylene may be oxidized to methacrylic acid, and butene-1 can be converted to crotonic acid.  The advantage of the invention includes maintaining high yields under moderate reaction conditions which is made possible by use of the novel catalyst which has improved catalytic activity resulting from its activation in the substantial absence of oxygen.

Abstract: Abstract:   The invention provides apparatus for the combined planting of seed and application of fertilizer.  The apparatus has a soil point for cutting a narrow slot-like furrow in soil.  A shovel for opening a second, wider opening in the soil is located above and behind the soil point in alignment therewith.  These two furrow cutting devices co-operate to form a single furrow having a narrow bottom part and a wider top part.  An upright plate-like shoe member having a width similar to that of the narrow bottom part of the furrow is located immediately behind the soil point and prevents soil from falling into the narrow part of the furrow.  A seed delivery tube is located immediately behind the shovel above the shoe member between the forward and rearward ends of the shoe member.  A fertilizer delivery tube is located immediately behind the rearward end of the shoe member.  The apparatus forms the narrow slot for the fertilizer and the wider slot for the seed before either seed or fertilizer is dropped into the soil, but the fertilizer slot is tem-porarily covered to prevent seed and soil from falling therein.

Abstract: Diamond-like, transparent, clear and uncolored carbon coatings with low internal stresses are generated on substrates by plasma discharge from the gas phase. For this purpose, a hydrocarbon gas or a mixture of hydrocarbon gases and pure hydrogen, if necessary in the presence of a noble gas, are admitted onto the substrate to be coated at a temperature between room temperature and -100.degree.C. Around the substrate an oxygen-free plasma discharge is produced by high-frequency excitation which is sustained by the gases admitted. The gases are excited, dissociated and ionized during plasma discharge and accelerated toward the substrate.

Abstract: ABSTRACT OF THE DISCLOSURE      The invention provides a chemical etching method for a semiconductor device, which comprises a step of forming a first layer of Gal_xAlxAs (0 < x < 1) having a surface (100), a step of forming on the first layer a second layer of Gal_yAlyAs (0 < y < 1) having a surface (100), and a step of chemically etching the layers from a level above the second layer and along the direction of <011>.  The slope angle of etch face of the second layer depends on the mol fraction y of the second layer, and the slope angle of etch face of the first layer depends on the mol fraction y of the second layer and the mol fraction x of the first layer.  These facts are best utilized in the invention so that the etch profile of the first layer may have a desired slope angle.  By utilizing this chemical etching method it is possible to produce by chemical etching a semi-conductor laser having a flat cavity facet perpendicular to a junction; it is also possible to provide an inner stripe type semiconductor laser having grooves whose side walls are perpendicular.

Abstract: HIGH CENTER SHOVEL       ABSTRACT OF THE DISCLOSURE           Standard shovels, particularly shovels used in deep  tillage  implements,  vibra  chisel  or vibra  shank cultivators and the like tend to push or roll the soil ahead in front of the shovel leading to high wear and heavy draft conditions.  The present shovel is V-shaped with  a relatively high  centre  thus  giving a plowing effect and turning the soil over and away upon each side thereof.  A substantially centrally located depression is formed when the shovel is pressed out thereby forming a recess on the front side and a flattened bearing surface on the rear side thus providing a good anchoring and bearing area when bolted through the flattened portion and onto the shank.  The bolt heads are protected and the invention can be incorporated also on shovels with wings or  sweeps  on  each  side  of  the  high  centre  central portion.
