A protective carton having a wall interconnecting a pair of sidewalls and having open ends wherein the interconnecting wall is provided with a pair of parallel cuts extending completely across the central portion thereof with the sidewalls each having a pair of slits and with the slits of each pair each adjoining an end of an associated cut. The interconnecting wall also has weakening means therein extending between and roughly perpendicular to the cuts. The cuts and slits define a U-shaped cons...

A roller comprises a rigid cylindrical sleeve formed of fiber glass which is coated with resin. The outer surface of the sleeve is machined to remove substantially all visible resin therefrom and to expose the fiber glass. The fibers of the fiber glass provide substantially fuzzy surface characteristics on the outer surface of the sleeve. An elastomeric sleeve is molded around the outer surface of the rigid sleeve. Fibers of the fiber glass extend into the elastomeric sleeve and define a zone ha...

Electrodes suitable for use for electrolytic purposes, for example for the electrolysis of aqueous alkali metal chloride solutions, are disclosed. The electrodes of this invention have an electroconductive substrate with an electro-conductive outer surface containing a spinel thereon, and an intermediate electroconductive layer between the electro-conductive spinel surface and the substrate which intermediate layer contains an oxycompound of a second transition series platinum group metal (ruthe...

This invention relates to a method and means for laminating superimposed layers of the same or different material by adhering said layers with a novel curable liquid adhesive composition comprising a polyene and a polythiol which, on exposure to ionizing radiation or a free radical generating agent, cures to a solid adhesive under ambient conditions. The novel adhesive can be used in bonding structural cellular material such as honeycomb cores and facings.

A crown particularly adapted for use with a liquid refreshment container wherein the crown is adapted to be turned off the threads on the container or pried off the container with a bottle opener. The crown has a smooth edge configuration so that it can be readily grasped by the fingers for turning without the fingers being cut by the sharp edges which are normal with a conventional serrated crown. The smooth edge configuration for the crown is secured by forming a lip portion on the peripheral ...

An antibiotic selected from the group consisting of Tumimycin and salts thereof. This antibiotic is an orange-red powder having the following average elemental analysis: carbon, 66.79 percent; hydrogen, 6.85 percent; nitrogen, 3.45 percent; and an infrared absorption spectrum as shown in FIG. 1 and an NMR spectrum as shown in FIG. 2. Tumimycin is useful as an antimicrobial agent.

A thermistor comprising a monocrystalline semiconductor substrate having at a surface thereof both first and second electrically energized electrodes and means for providing a higher current density at the central region of this surface than at the edge of this surface and at the other surfaces of the substrate, which means comprises at least one electrically-floating field-conducting electrode between the first and second electrode. In one embodiment, the field-conducting electrode is spaced fr...

One-piece, light-weight, transparent telescope mirror blanks consisting essentially of one integral shaped mass of transparent, low-expansion, at least partially crystallized glass ceramic having a pair of oppositely disposed face surfaces and a plurality of separate cavities between the face surfaces. One of the face surfaces of the mirror blank has a plurality of openings therein, each of the openings being in communication with a cavity. The cross-sectional area of the opening is smaller than...

A chair and a method of making a part of the chair from wood and a part of the chair from molded plastic wherein a screw rod or naillike object is molded in place in the chair back thus providing a readily assemblable joint which is assembled in combination with a wood chair.

A furnace and a method of manufacturing such a furnace wherein a refractory concrete base is prepared at the bottom of a cylindrical tank, an induction coil is then placed over the base and thereafter puddled clay is packed inside the coil to form a crucible. The base is prepared separately in a removable bottom cover which is fixed to the cylindrical part and a further removable bottom cover is prepared for replacement purposes. The present invention relates to a furnace and to a method of maki...
