Abstract: This invention is directed to an aerosol container system with two separate chambers, each of which contains a component to be mixed with the other component just prior to use.

Abstract: A rotatable liquid hair treatment medium applicator comprising a container having a distal face surrounding its opening which is at an angle to its verticle axis, a conical applicator head rotatably mounted around the mouth, and an applicator mouth co-rotatably projecting from the applicator head at an angle to the common central axis of the opening and applicator head.

Abstract: A radially expandable hair curler comprising a generally cylindrical hollow body, a detachable holding strap stretching from one longitudinal end of the body to the other, and internal mechanical device for expanding and contracting the curler body.

Abstract: Combinable bottle assembly (1,6) consisting of two separately fillable bottles designed to be fitted together one above the other, can be formed inexpensively of plastic, filled and stored separately from and independently of one another and can readily be connected and tightly combined with one another to form a two-compartment container convertible to a one compartment container.The floor or bottom wall (12) of the upper bottle (1) is formed as a separate cylinder element (3) having an annular connecting plate (13) which connects a skirt wall (14) of the cylinder element to the wall (15) of a central nozzle (9) arranged concentrically therein, forming a throughflow passage (16) which is closed by a stopper (10). The lower bottle (6) comprises an elongate neck having an external screwthread (33) which is engagable with an internal thread on the elongate nozzle to permit the second bottle to be screwed into the nozzle to a connecting position to dislodge the stopper and open the containers to each other.

Abstract: This invention relates to a novel continuous process for producing a hair curler comprising an elongated foam-plastic body with a substantially axially extending wire insert which is shorter than the length of the elongated foam-plastic body.

Abstract: Equipment for the through-connection of color television signals between a broadband network BN and video sources and video using equipment including a first video bus VB1 to which a plurality of source connection assemblies QAB1 through QAB3 can be connected with switching sets S1 throgh S3 is provided. A second video bus VB2 to which a plurality of using equipment connection assemblies SAB1 through SAB2 are connected and including a switch-over assembly UB which has input lines L.sub.E and output lines L.sub.

Abstract: The material used for the production of cores for precision molds is a metal which is oxidizable at relatively low temperatures, i.e., below the solidification temperature of the melts for pouring, and which passes directly from the solid state to the gas state by oxide sublimation. This greatly speeds up the dissolving of cores, particularly small diameter cores, out of the castings.

Abstract: Flask which is fitted with a closure which can be sealed in such a manner as to ensure sterility of its contents and which is characterized in that it is provided at its head part with a thread, preferably a round thread which is connected with a conical ring, and in that the corresponding closure cap has an inner thread so formed as to correspond on the flask, and in which the open end of the closing cap is provided with a recess into which the tamper-proof ring is pressed in.

Abstract: A process for the preparation of a container closed under sterile conditions and containing lyophilized material, which comprises1. filling the material to be lyophilized into a container,2. putting a rubber stopper and a closing cap loosely on the container,3. introducing the container with its contents into a lyophilization apparatus,4. lyophilizing the contents,5. within the lyophilization apparatus and in a single operation, pressing the rubber stopper deep into the container, at the same time pressing the closing cap onto the same, and6. removing the container closed under sterile conditions from the lyophilization apparatus.

Abstract: The subject matter of the invention is a closable sterile container and the associated closure cap, which can simultaneously be used as a pipette and which is a tamper-proof closure in conjunction with the container.
