Abstract: ABSTRACT:                       An electric discharge tube, in particular a television camera tube, is provided with a hermetically sealed electric leadthrough which connects a thin-film electrode provided on the inner wall of the tube envelope electrically to an electrically conductive layer provided on the outer wall of the envelope.  The leadthrough consists of an aperture in the envelope having a conductive layer provided on the wall of the aperture.  The aperture is hermetically sealed by means of a plug of thermally devitrified glass which is provided in the form of a suspension of a devitrifiable glass powder in an organic binder.  For the manufacture of the lead-through the envelope of the tube is subjected to a temperature treatment in which in a first temperature range the binder is fired from the suspension while maintaining an oxygen-containing atmosphere and in a second tempera-ture range the devitrifiable glass is devitrified while maintaining a non-oxidizing atmosphere.  This method re-sults in a hermetically sealed leadthrough without excessive oxidation of the thin-film electrode occurring, while the occurrence of deformations of the glass envelope at the area of the leadthrough is avoided.

Abstract: CHANNEL TYPE TERMINAL CONNECTORS AND METHOD OF MAKING            Abstract of the Disclosure Forming of wire contacting jaws for a channel type electrical terminal of conductive sheet metal is disclosed, without diminishing the length of the terminal, by first obtaining a stretching of the conductive metal into a preliminary displaced configuration in a first die.  Then reverse forming and coining the metal into a jaw formation deeper and narrower than the first configuration.  Then in a third die substantially removing the reverse curvature, with added coining and stretching of the metal, into a final jaw formation which is deeper and narrower than that obtained in the second die, without rupture of the metal.  Slight reverse curvature is retained adjacent the juncture of the sides of the jaw with the body of the terminal.

Abstract: TUBING TO SLEEVE INTERLOCK FOR GAS SERVICE CONNECTOR Abstract of the Disclosure The gas carrying plastic tubing at the meter end of a gas service connector is axially interlocked to its pro-tective metal sleeve by means of an interfitting annular gasket surrounding the tubing in the intervening space between the tubing and sleeve.  The gasket is axially sand-wiched in compression between a pair of annular insert rings, the innermost of which is seated against an annular shoulder formed in the internal diameter surface of the sleeve.  Securing the outermost ring is the radial flange of a ribbed lock insert positioned in the tubing and termi-nating outward thereof in the radial flange which is staked to the metal sleeve about its periphery.  The compressive forces imposed on the gasket causes a radially inward annular bulging of the gasket locally deforming the plastic tubing into a conforming interfit with the ribs and spacings of the insert.

Abstract: ABSTRACT OF THE DISCLOSURE   A process is provided herein for preparing an ethylene-propylene copolymer having a melt index ranging from 0.01 to 10 and a density ranging from 0.910 to 0.945.  In such process, ethylene and 6 to 100 mol% thereof of propylene are copolymerized in a substantially solvent-free vapor phase condition and in the presence of a catalyst consisting of a solid substance and an organoaluminum compound, the solid substance containing a magnesium-containing inorganic solid compound and a titanium compound and/or a vanadium compound.  The polymerization reaction can be performed in extremely high activity and extremely stably with reduced production of coarse or ultra-fine particles, with minimized adhesion to the reactor and conglomeration of polymer particles.  The copolymerization can be performed at relatively low temperatures to provide medium or low density ethylene copolymers having a high melt index.  The copolymer formed has superior transparency and elasticity and has a high resistance to impact and environ-mental stress cracking. Thus, it can be formed into films, sheets, hollow containers, insulation for electric wires by the known methods of extrusion molding, blow molding, injection molding, press forming and vacuum forming. The films have the properties of excellent transparency, anti-blocking properties, heat sealing properties and flexibility. Because of its large elongation, extremely thin films may be formed. Because its crystallinity is high and its heat resistance is good, it forms an unsticky film of high transparency, useful for packing and agricultural uses.

Upon hydration, the zeolite becomes warm, thereby helping to relieve pains associated with various musculoskeletal problems. An especially useful composition involves an ointment or balm that contains a combination of functional ingredients.  A conventional analgesic such as a salicylate that can be absorbed through the skin supplies one form of relief that generally requires a period of time to become effective.  When combined with the zeolite, which begins to hydrate at once, immediate relief is provided through the generated warmth.
