Abstract: As a rule a melt-good consisting of glass fragments and glass batching will be moist and tend to agglomerate and bridge-form when being preheated in a plate heat-exchanger 10 whereby the travel of the melt-good through the plate heat-exchanger 10 may be blocked. To remedy these drawbacks, the preheating stage is preceded by a drying stage of the moist melt-good. For that purpose, in the intake zone of the melt-good, the moisture of the melt-good is evaporated by means of a separate feed of hot heating gas into the already cooled flows of heating gas. At the same time the heated melt-good is made to pass through cavities 12 through which the steam may escape to the outside. Thereby condensation shall be precluded and only fluid or friable melt-good arrives at the preheating stage.

Abstract: In order to manufacture joint-adapters for doubly curved and preferably single-layer lattice girders with improved strength and lesser weight while at the same time also allowing relatively high curvatures of the lattice girders, the invention suggests to make the joint-adapters 11 predominantly frusto-conical. Their plane rest surfaces 22 for the butt ends of the bars 10 of the lattice girder subtend the same or substantially the same slope angle .alpha. with the extended joint-adapter main axis 16 as the residual part of the joint-adapter wall. The slope angle .alpha. of the rest surfaces 12 relative to the extended joint-adapter main axis 16 determines the curvature of the lattice girder. In the preferred embodiment mode of the invention, the wall thickness of the frusto-conical joint-adapter 11 is of constant thickness over the entire height H at its thinnest sites in the vicinity of the rest surfaces 12.

Abstract: A sterilization apparatus for sterilizing medical instruments such as scalpels, tweezers, needles and the like utilizes an electrically heated inert material as the sterilizing media. Instruments to be sterilized are positioned in the inert material and become aseptic within 10 to 30 seconds. The sterilization apparatus includes a cylindrical metal tube which can be electrically heated in a short time to a high temperature (200.degree.-300.degree. C.). The sterilization apparatus also includes insulation surrounding the heated cylindrical metal tube and an insulated base. This insulation ensures that heat is conducted to the inside of the tube and is isolated from other parts of the apparatus, particularly, the electronic components. With this insulation, a compact sterilization apparatus can be made without damage to the apparatus components due to excessive heat.

Abstract: An improved rocket motor and a method for its manufacture are characterized by the provision of a thermoplastic elastomer binder in the outer casing, the insulation layer, and the propellant. When the motor is heated to the melting point of the binder, the bondlines between the propellant and insulation and between the insulation and casing are simultaneously fused to form a unitary motor structure.

Abstract: To render more economical the manufacture of galvanized bar segments 10 illustratively used for three-dimensional frameworks, the components of the bar segments 10, namely the hollow bar 11 and the end pieces 12, are galvanized before being assembled. The ring welds between the galvanized components 11, 12 are implemented by laser welding. Because of the high energy density of the laser welding beam and on account of the narrow ring-weld seams 18 so formed, a zinc coating 24 supplied from the zinc coats 22 of the adjacent components 11, 12 is created during welding and covers each surface 25 of the ring-weld seams, as a result of which, following welding, the bar segment 10 also is provided with a zinc coating 24 covering the surfaces 25 of the ring-weld seams protecting them against corrosion.

With the chamber filled with propellant, the fill valve is brought into engagement with the bottom of the motor and opened. The injection cylinder includes a piston which is extended into the chamber to inject propellant into the motor via the valve. The length of travel of the piston is accurately controlled to govern the precise quantity of propellant injected into the motor.

Abstract: A weight bench having a slidable seat construction includes a two piece slidable bench which is pivotally connected to the frame of a weight bench. A sleeve, designed to travel along a frame member, supports the seat portion of the bench at a pivotal attachment and by an angle adjusting bracket mechanism. A back rest portion of the bench is pivotally attached at one end thereof to the sleeve. The other end is connected to the frame by a support which is pivotally attached to both to the frame and the underside of the back rest portion. The sleeve is lockable in a given position along the length of the frame member providing support therefor. Sliding movement of the bench produces simultaneous adjustment of the inclination of the back rest due to the double pivotal attachment of the support. The sliding seat assembly is particularly adapted for weight benches having uprights with barbell supports.
