A current-limiting circuit breaker incorporates an improved ultra high-speed solenoid operator for carrying continuous current loads substantially in excess of 100 amperes without exceeding 80.degree. C. The solenoid operator is comprised of a generally C-shaped nonhelical winding of substantially one full turn having a cross-sectional area controlled to provide a minimum space factor and flux path, a magnetic cup-shaped stator including an efficient flux path return shell confining the winding ...

A high-power high-isolation switch for high-power devices which switch power to one of several alternative output ports. Unwanted leakage is attenuated and high-isolation between the output ports is obtained. In addition, protection against burn-out during abnormally high leakage conditions is provided where the devices employed are not self protecting.

A high temperature high pressure apparatus which comprises: an annular die having a straight cylindrical bore and a substantially conical face in adjacency outwards with each end thereof, a pair of tapered punches which are in opposed and axial alignment with the die so that a conical face of each punch is substantially in parallel with that of the die, a pair of inner gaskets, each of which is made of fired refractory and is arranged in direct abutment on the conical face of the punch and the b...

A convertible high chair including a base, a board attachable to a lower portion and to an upper portion of the base, a chair attachable to the base by means of mechanical fasteners, the chair when attached to the base, and the board when attached to the lower portion of the base forming a high chair, wherein the chair includes a plurality of chair parts which are storable separately and which are assembled together by means of mechanical fasteners, and the base includes a plurality of base part...

A high pressure/temperature device comprises two complementary dies with recesses in locking surfaces thereof, the recesses forming a reaction chamber accommodating a reaction mass container. Radial slots in the die locking surface are intended for disposing therein electric conductors connected to a measuring element, e.g. a thermojunction, incorporated into the reaction mass.

A manufacturing method is provided for the production of high density, high carbon, sintered powder metal steels. The composition consists of iron based powder, graphite, lubricant, and possibly at least one alloying element from the group of chromium, copper, manganese, molybdenum, nickel, niobium or vanadium. The composition is compacted in rigid tools, sintered and during cooling an isothermal or slow cooling treatment is introduced between 650.degree. C. and 750.degree. C. The isothermal or ...

The pressure measurement system utilizes two bourdon tubes with an active side connected to a test specimen and a reference side connected to an outside source. The tubes are attached to a single extensometer measuring relative displacement. The active side deflects when gases vent a specimen failure. The reference side is independently pressurized to a test pressure and provides a zero reference while providing a pressure calibration reference for the active side. The deflection noted by the ac...

Improved batteries described herein generally comprise an electrolyte having lithium ions and a cathode comprising submicron metal vanadium oxide particles. In some embodiments, the battery demonstrate an accessible current capacity of at least about 220 mAh/g when pulsed in groups of four constant energy pulses at a current density of 30 mA/cm.sup.2 to deliver 50 Joules per pulse. The four pulses of a pulse train are separated by 15 seconds of rest between each pulse, and there are 6 days betwe...

The invention is directed to a high-resolution high-apertured objective which includes an object plane (1); a first lens group (LG1); a second lens group (LG2) downstream of the first lens group; a beamsplitter (17, 18, 22, P) downstream of the second lens group; a concave mirror (21); a system diaphragm (A) interposed between the beamsplitter and the concave mirror; a third lens group (LG3); the objective defining an image plane and being configured to provide a reduction scale (.beta.) in the ...

A lipstick composition comprising a gloss-enhancing amount i.e. about 0.5 to about 8 weight percent of isohexadecane in a conventional lipstick formulation is disclosed.
