Abstract: For manufacturing articles of plastics, rubber or any other material a mold or die assembly comprising a mold or die base assembled from repetitive modular standard elements consisting of substantially "ready to use" interchangeable base plates is provided by the invention.The base plates are prefabricated by high-precision castings or galvanoplastics or any other similar high-precisious non-cutting method of manufacture.At least two of such base plates are, as mold or die plates, provided with a pre-determined number and arrangement of finished to sized, prefabricated cylindrical bores or piercings of any non-circular, mainly polygonal cross-section. Each of said bores or piercings is capable of fittingly receiving an interchangeable mold or die insert carrying the individually designed (negative) mold or die cavity surface for forming the particular article(s) to be manufactured.

Abstract: The invention relates to a process for preparing antispasmatic products which are to be attached to the skin. One or more kinds of metal or metallic substances and/or deficiency and/or trace elements and in a given case the active ingredients of some known pharmaceutical agent is applied to a carrier. The deficiency and/or trace element and in a given case the active ingredient of the known pharmaceutical agent medicament, which are present, are applied in form of a powder, a liquid or in gaseous form. The powdered, liquid and gaseous substances are placed into a recipient, e.g. bag with a permeable wall onto the carrier. Preferably, adhesive strips are provided on the margins of the carrier, while the substances on the carrier are covered with a removable protective layer. If required, the carrier is pretreated with a weak base or acid prior to the application thereof.

Abstract: Disposable syringe made of plastics, for medical purposes, consisting of a barrel (1), a piston (2) provided with a plunger shaft (3) guided at a distance from the barrel wall, and a closure cap (4), the piston (2) being releasably joined to the plunger shaft (3). The piston (2) is at least partially softly resilient due to the fact that on the piston periphery wall parts of greatly reduced wall thickness are present. The closure cap (4) contains a sufficiently long, stable slide bearing for the plunger shaft (3), so that deformation of the latter, arising out of off-center application of force in the retracted piston position, and out of the tendency of the relatively thin plunger shaft (3) to bow or buckle, will not be transferred to the piston (2).

According to the improvement, the unit for converting the wind energy is a wind motor (1) having rotor blades (41) and a control mechanism (42) for constant load on the rotor blades (41) independently from the wind intensity, the unit for converting the kinetic energy is a device for compressing the air to a pressure greater than that of the atmosphere and the unit for supplying water comprises a natural or artificial source of water such as a well (21) or a container operated by pressurized air and structure for temporary storage of the water and for controlling the water bailing from the source of water.

Abstract: The invention relates to a gas-heated or kerosene-heated boiler for warm water, hot water or for steam generation having a substantially horizontal cylindrical combustion chamber defined and surrounded by a flue tube (1) consisting of a plurality of annular ring tubes (b 2) that are arranged in succession for conveying a suitable heat carrier and are held together by means of annular distance strips (3). At least some of the annular ring tubes have different inner cross sections and/or are arranged in a manner of having different, unequal spacing distances one to the next. Thus, a substantially uniform main diameter of the flue tube (1) is maintained, and despite of this, the flow of heat carrier circulated is harmonized with the thermal load which is non-equally distributed along the axis of the combustion chamber, resulting in improved utilization of the heat energy radiation at substantially constant wall temperature along the flue tube (1).

Furthermore the invention relates to a process for preparing these compounds.The new gonadoliberin derivatives can be effectively used for the reproduction process of fish, birds and mammals.

Abstract: Framework truss with changeable cantilever length, comprising an articulated grid structure which is hingedly secured at two fixed points against a wall or any other carrier element. Said framework truss is characterized in that at least two articulated grid panels are joined together having the shape of a parallelogram and projecting in the cantilever direction (L) from two fixed articulation points (A, B) situated at a certain interval (h) from each other. The articulated grid panels are comprised of parallel articulated bars (21, 22, 23, 24, 25 and 26), as well as coupling rods (31, 32, 33) connecting them by pairs from their ends between the articulation points (C1, D1; C2, D2; C3, D3) and of which the length remains always equal to the interval (h) separating the fixed articulation points (A, B).

Abstract: A constructional toy set has building members and coupling members having dimensions which are equal to, multiples of, or specific fractions of a basic unit size, have a basic thickness or a multiple thereof, have through holes of basic hold diameter or multiples thereof with shapes symmetrical to either or both longitudinal and transversal axes thereof. End regions of the members may be semi-circular in form, and the through holes are positioned on the longitudinal axis or symmetrically to the sides thereof and at distances from themselves and the outermost points of the end region equal to set fractions of the basic size, equal to the basic size or to multiples thereof. The coupling members may be joined by threaded bolts and whose length is several times as long as the basic thickness. Nuts engage the bolts to lock the coupling members together.

Abstract: The invention concerns to a carcase or framework, particularly for furniture. It has columns, interconnecting pieces attached to them and clamps joining the columns and interconnecting pieces. Essentially, the columns consist of parallel column members attached to each other. At least at two places--favorably at the ends of the column members--they are attached to each other by means of a coupling member overlapping two column members and/or intermediate interconnecting piece joining two columns via two releasable clamps. Each column member is clamped to the coupling member and/or the interconnecting piece. The carcase has interconnecting pieces which join the column members. They have sections dimensioned to the drift holes made by the notches on the facing surfaces of two column members. Adjacent these drift holes the interconnecting pieces have shoulders, edges or similar configurations which are supported by the column surfaces and which prevent displacement relative to the columns.
