Abstract: There is provided a method for producing a self-supporting ceramic composite comprising (1) a ceramic matrix obtained by oxidation of an aluminum zinc alloy to form a polycrystalline oxidation reaction product of the metal (10) with an oxidant, and (2) one or more fillers (12) embedded by the matrix. The metal alloy (10) and permeable mass of filler (12) having at least one defined surface boundary (14) are oriented relative to each other so that formation of the oxidation reaction product will occur into said mass of filler (12) and in a direction towards said defined surface boundary (14). On heating the metal (10) to a first temperature above its melting point but below the melting point of said oxidation reaction product to form a body of molten parent metal, the molten metal reacts with said oxidant to form said oxidation reaction product which infiltrates said mass of filler (12) to said defined surface boundary (14). The resulting infiltrated mass is heated to a second temperature in order to remove or oxidize at least a substantial portion of any residual non-oxidized metallic constituents from or in said infiltrated mass without substantial formation of said oxidation reaction product beyond said defined surface boundary (14), thereby producing a self-supporting ceramic composite.

Abstract: Using the adjusting device (30), the switching ram (26) of a spring apparatus (19) is adjusted from a locking position into an unlocking position of the spring apparatus (19). In this unlocking position, the chair frame, which consists of a seat support (5), a backrest support (7) and a foot part composed of a support column (1) and a support part (2), can be adjusted in its position. Compared to other designs, the locking and unlocking position is set by a single handle (58) of an operating element (31). This causes the adjusting device (30) to be simpler and more easy to operate.

Abstract: In a process for machining workpieces using a laser beam, optical and/or acoustic signals generated in a machining region are recorded and used to obtain actual values which are compared with corresponding reference values of a processing diagram specific to the material and to the machining. The results of the comparison are used to control the machining process by influencing it in a predetermined manner. In order to influence the machining region with a process gas in an appropriate and cost-effective manner, process gas is supplied to the monitored machining region in which the optical and/or acoustic signals are recorded, and the type of process gas and/or at least one gas supply parameter are continuously adjusted.

Abstract: It has been found that when layered preforms are being injection molded utilizing at least two materials, it is possible to maintain the same horizontal and vertical pitch of adjacent cavities as is possible when each mold cavity is being filled with a single material. Most particularly, it has been found that when the percentage of the material to be injected into a mold cavity is relatively high, it is possible to utilize a single metering pot (18) for four adjacent mold cavities (10). On the other hand, if one of the materials to be injected into a mold cavity constitutes a relatively low percentage of the volume of a mold cavity, it has been found that a small metering pot (40) must be provided for each of the cavities of the four cavity mold (10). Most particularly, with this combination, it is possible to maintain the pitch of the single material mold and thereby maintain the small size of existing injection systems as opposed to an increase in the pitch of the mold cavities which would increase the size of the mold structure.

Abstract: An auxiliary video input terminal (S-terminal) (60) couples luminance amd chrominance input signals to respective inputs of peaking circuits (52, 58) in the display processor (40) of a receiver. The chrominance input signal is subjected to pre-distortion (de-peaking) (80) to correct for sideband amplitude distortion in the chrominance peaking filter of the receiver thereby preventing color distortion in displayed images. The luminance signal is subjected to additional peaking (70) at a frequency greater than the characteristic peaking frequency of the luminance peaking filter thereby enhancing the sharpness of wideband luminance input signals displayed by the receiver. <IMAGE>

Abstract: A massaging pad is pressed against discrete areas of a subject person's scalp and worked from side to side to thereby move the skin relative to the underlying skull. The pad (20) is cloth material that is compressible as necessary to avoid the discomfort of pressing a hard metal probe against the scalp. Electrical current is passed through the pad and into the subject person's scalp by connecting the pad to an electrical conductor from an electrical current generating device (12) which generates oscillating voltage to the pad in a low range and at a variation of voltages. The pad includes a highly conductive metal bulb, e.g. of copper metal coated with silver and gold, and a moistened padding, e.g. wool that surrounds the bulb. The ground contact is hand held by the subject person so that electrical current is directed down through the skin layers during the massaging process.

Abstract: A laundry stand which can be clamped between ceiling 1 and floor 2 has a central upright tube 3 with an outer tube 4 and with an inner tube 5 displaceable therein. The inner tube 5 is supported on the ceiling 1 via a compression spring 13. For bracing and locking the upright tube between the ceiling 1 and floor 2, there is a clamping lever 18 which is mounted on the outer tube 4 so as to be pivotable about an axis 20 extending transversely relative to the longitudinal axis of the upright tube 3 and which has, on its basic body 21 with a cylindrical outer face, some tooth-like projections 23 which come into engagement with tooth spaces 24 of a rack 19 attached to the inner tube 5, when the clamping lever 18 is rotated in the clockwise direction. The inner tube 5 is thereby pushed upwards, the compression spring 13 being compressed. In its end position, the clamping lever 18 catches in a blocking nose 28 of a resilient catch device 25. After the catch device has been released, the spring 13 presses the inner tube 5 downwards, with the result that the clamping lever 18 is pivoted and the tooth-like projections 23 come out of engagement. The inner tube 5 can then be pushed freely into the outer tube 4. <IMAGE>
