Abstract: A ceramic workpiece holder for use in kiln treatment of ceramics includes a base member of generally elongated configuration. This base can have two, three or four or more legs and can be formed with an upstanding support post intermediate its ends. Each leg of the base member carries a pair of blade members which can extend in any direction and can especially be placed parallel to its longitudinal axis. The blades can be positioned at an angle or can extend vertically upwardly with the upward edges extending parallel to the horizontal or at an angle thereto. Located in the support post are a plurality of pin members also extending generally parallel to the longitudinal axis of the base member and are spaced apart to define support points. A pair of grooves extend along each leg, one each for holding each blade. These grooves extend further than the length of each blade and are of a length and width to accommodate a blade during expansions and contractions.

Abstract: Cooking apparatus and method for preparing meats to suit individual tastes of different consumers. The meat is subjected to electric current heating to cook the meat and to radiant broiling to char its surface. The cooking current passing through the meat is regulated in response to a comparison of an input corresponding to the desired degree of cooking and an indication of the interior temperature of the meat as it is being cooked. The apparatus and method are particularly suited to handle effectively a variety of individual orders at substantially the same time.

Abstract: An improved cuvette unit suitable for use in blood oxygen analyzing and plotting apparatus in accordance with U.S. Pat. No. 4,304,488. A cuvette cavity, preferably cylindrical, is formed in a transparent plastic block. A Clark electrode is embedded in said block and arranged to project into the interior of the cavity. A horizontally-directed gas inlet is introduced adjacent the bottom of the cavity, for introducing the gas (oxygen, or an inert gas) and also providing efficient agitation. Among the benefits are the avoidance of mechanical agitation elements and the speeding up of the oxygen association and dissociation tests.

Abstract: A three-dimensional puzzle game having six sides comprising a cube wherein each side includes nine squares forming three columns intersecting three rows, any of the columns and rows being rotatable about an orthogonal axis of the cube with a single individual such rotation being accomplishable at a time, each of the six sides carrying a different integrated, invertible pictorial design with interchangeable portions which appear on each of the nine squares of each side.

Abstract: A method and system for measuring the oxygen carrying capacity of normal and abnormal hemoglobins and red cells under controlled pH, ionic strength, temperature and gas conditions is described. A blood sample and a physiologically balanced medium are placed in a cuvette and means are associated therewith for measuring the fractional saturation of the sample and the partial pressure of the oxygen (sometimes referred to as the oxygen tension) and provide output signals to an X-Y plotter for continuous recording. Preferably, means for maintaining the temperature of the medium and the blood sample is provided.

Abstract: A reservoir brush useful for washing automobiles and the like has a vacuum creating pump operable in a chamber in which an expandable bladder resides in order to draw fluid through the head of a brush to which the bladder is attached and into the bladder, wherein the chamber is vented, facilitating collapse of the bladder and run-out of the fluid when the pump is not operating, the pump including a check valve facilitating the pumping action.

Abstract: A utility brush usable to wash various objects includes a brush head and a handle member, the former including cleaning means such as bristles extending from one face thereof. Also included are port means formed through the head to provide communication between the cleaning means and a reservoir containing a cleaning fluid whereby the cleaning fluid can be fed into and out of the reservoir. Associated with the reservoir means is check valve means for allowing air to be exhausted from the reservoir during filling and for maintaining the reduced pressure in the reservoir means during the release of the cleaning fluid.

Abstract: A recuperator-type heat recovery apparatus may have a configuration for passing hot waste gases through an elongate, extended cyclone-type circulation path within a constricted area effecting the flow of the gases against a heat transfer surface and providing an extended retention time for radiating and conducting heat into this heat transfer surface and concurrently for changing the velocity of the gases resulting in a separation or fallout of heavier particles of dust and other matter entrained in the gases; a controlled introduction of abrasive particles operates to clean away buildup of contamination and dust deposits from all surfaces within the apparatus, the spent abrasive particles and dirt separating from the gases and being recovered.

Abstract: A slip resistant mat assembly for use on boats and other pleasure craft has a custom molding providing an edge trim and being usable for securing the mat in place against both vertical and lateral movement, whereof the mat portion includes vertically downwardly extending studs upon which it stands, a portion of these studs passing into the molding and being interlocked thereto, the molding being securable to the surface upon which the mat studs rest.

Abstract: A method for treating articles with heat and pressure is disclosed. The articles are placed in an isostatic press, the press is evacuated of air and thereafter filled with an inert gas, the pressure and temperature of which is raised to predetermined levels. These predetermined levels are maintained for a period of time sufficient to effect the treatment, and thereafter the inert gas is circulated to promote cooling of the gas and reduce the cooling time of the press and the article treated.
