A lined chimney having upper and lower support means for the liner, and at least two expansion joints separated by toggle sections between the upper and lower liner supports, at least one expansion joint having plural expansible or compressible hangers on the exterior thereof, and a method for providing the same.

Apparatus for providing temperature-gradients, incorporating a block of thermally-conductive material provided with a heating source at one end and a cooling source at the other end, and adapted to subject a group of like specimens to different temperatures.

The outwardly flanged end of a glass tube is hermetically sealed by means of a pure or indium coated aluminum wire gasket which is squeezed at a pressure of about 5,000 pounds per linear inch of wire between the glass flange and a metal closure plate and heated to about 482.degree.F or above. The pressure is applied by C-clamps which grip the closure plate and a split ring collar surrounding the tube. An aluminum cushioning gasket is disposed between the collar and the glass flange to prevent gl...

Process for providing a backing on a carpeting material comprising (1) forming a heat curable polyurethane forming froth which is substantially structurally and chemically stable but workable at ambient conditions, (2) applying said froth to the back of carpeting; (3) shaping said froth and (4) curing the resultant shaped froth at a temperature of at least 70.degree.C. to form a cured polyurethane foam backing on said carpeting material.

A universal time providing clock includes a rotatably mounted support annulus which has hour designating numerals on opposite faces, and a clock body is rotatably supported in the annulus. The clock body includes a front face with clock hands driven by a clock motor located within the clock body. On the rear face of the clock body there are mounted a pair of concentric hemispherical shells which are rotatable about a central axis perpendicular to the clock face and the inner and outer shell peri...

The specification describes a device for the preparation of Irish-Coffee which comprises a number of rotary plates arranged to receive glasses in which the Irish-Coffee is made.

In a tension providing device having a rotary shaft which rotates the spring force in an inserted casing, a pushing body which slide in an axial direction by the aid of the rotation of the rotary shaft, a seal bolt screwed with the base end portion of the casing, and a boot which covers between casing and pushing body, the mixing of dust and foreign matters from outside and the leakage of the lubricant coated or filled in the inner portion are prevented due to the covering of the boot and seal w...

A circuit for providing a controlled resistance, the circuit comprising a pair of terminals for input of an excitation current, variable resistance means connected in the current path between the terminals, means for deriving a first signal representing the value of the voltage appearing across the terminals, means for deriving a second signal representing the value of the excitation current, means for generating a third signal representing a selected value of resistance to be provided between t...

A method for mounting an electrical receptacle between a printed circuit board and a parallel spaced front panel. A molded thermosetting plastic connector body holds a pair of contact terminals which have lugs projecting from the rear of the connector body which are secured to a printed circuit board. A front cover for the connector body is made of resilient thermoplastic material and has resilient ears and fingers to engage both an opening on the front panel and the connector body. Thus the con...
