Abstract: Electrical current supply terminal, especially for discharge tubes of light sources having a high pressure gas discharge.The invention is concerned with an electrical feed through, especially for discharge tubes of light sources having high pressure gas discharge, which current supply terminal is passed through a ceramic material, preferably from aluminum oxide and with a binding material is hermetically binded thereto, the heat expansion coefficient of which is appropriately selected and which is preferably vitreous enamel.In order to eliminate the difficulties resulting from the different heat expansion coefficient of ceramics, binding material and the metal material, the feed through is formed from a bundle of metallic threads.The bundle comprises preferably strands or braids and as material preferably molybdenum or tungsten is used.

Abstract: A process is disclosed for the preparation of an endogenous anorexogenic substance obtained from blood serum. The anorexogenic substance itself is also described having a specific activity of 100 units/mg.

Abstract: A linear overpressured thin layer chromatographic apparatus comprises a base plate 3 supporting a sorbent layer 1 over which a membrane 4 is filled. The membrane 4 is externally pressurized by a fluid medium 10. A transparent cover plate 5 is fitted over the membrane 4, and there are sealed inlets 6, 7 passing through the cover plate 5 for the introduction of the mobile phase and the samples.

Abstract: Described is the method of preparing satietin, a peptide separated from plasma or serum and possessing the effect of inhibiting food intake. Also described is the product satietin.

Abstract: This disclosure pertains to a handle, housing a battery and a switch and is adapted with a removable blade securing bar extending transverse to the longitudinal axis of the handle. A plurality of blades are removably engaged within a series of spaced apart notches in the bars. A lamp is secured to the handle providing a convenient work light covering the area that includes a series of blades extending parallel to the longitudinal axis of the handle when the blades are secured within the notches. Each blade is adapted with at least one cutting edge and may be secured to the bar with the cutting edge extending in a preferred location, thus enabling the user to select either of two types of cutting edges or to position a variety of cutting edges of the adjacent blades in a cutting work plane and to position the blades selectively in the notches, providing thereby a variety of cutting widths.
