Abstract: A boiler for a heat sensitive working fluid in which there are three systems, first, a stream of hot combustion gas system, second, a heat transfer fluid system and lastly, a heat sensitive working fluid system. The heat transfer fluid is at the interface between the hot combustion gas and the working fluid so as to prevent the formation of hot spots.

Abstract: A flexible hose wherein the majority of the mass and the strength are located at the radially outermost portion of the hose. The hose is constructed by combining a relatively rigid radially outermost cap with a relatively flexible inner membrane.

Abstract: A rivetless anchor nut having an internally hollow shaft with a head on one end and a broken exterior surface on the other end. A malleable collar is deformed into engagement with the broken exterior surface to lock the shaft in a hole in a workpiece.

Abstract: A bench for supporting two persons engaged in sexual intercourse including a narrow platform for supporting the male in a supine position, arm and leg cradles for supporting the male in a spread eagle position, and a frame position to provide hand holds for a female standing straddle of the narrow platform.

Abstract: An elliptical suturing cuff for a mitral prosthetic heart valve with a round planform. The suturing cuff is constructed from a single piece of seamless knit tubing. The radially enlarged portions of the cuff are positioned generally adjacent to the pivot and retaining structure on the valve base.

Abstract: An articulated frame hanging chair, the frame of which includes an articulated parallelogram in which the exposed scissoring intersections are shielded and the articulation of the frame is adjustably limited to prevent the center of gravity of the hanging chair from shifting so as to dislodge the user in an unsafe manner.

Abstract: A music holder which has a foot designed to be mounted elastically against the machine heads of a guitar and a leg which receives musical reference material between two spaced apart plates in such a location that the reference material is securely positioned in plain view of the musician and is generally concealed from an audience viewing the face of the guitar.

Abstract: A blood filter in which the pore size of the filtering media generally decreases through a series of at least three stages where the filtering capacity of at least the first stage is chosen so as to accommodate without substantial impairment of function the quantity of large particle size debris which is normally present in a predetermined amount of blood. The filtering media is composed of several plies of porous material including both depth and screen filter elements. These filter elements are arranged in one or more elongated bands. The bands are spirally wound into a cylindrical form around a generally rigid, perforate core. The ends of the spirally wound cylindrically configured filter are sealed to produce a filter cartridge. The filter cartridge is in turn sealed into a container which has blood inlet and outlet ports arranged so that blood normally flows radially inwardly through the filter.

Abstract: A cap constructed of foamed synthetic polymeric material which is impregnated with a hair revitalizing oil composition is placed over the scalp portion of a human head. An oil impervious film is placed over the exterior of the cap, and heat is applied to the cap for a period of time sufficient to allow the hair revitalizing oil composition to permeate and saturate the hair.

Abstract: An article of manufacture for and a method of playing the skidwheel game. The invention comprises a longitudinally disposed generally flat playing surface with a design thereon containing value zones, used in combination with automobile steering wheel playing piece having a generally circular periphery which is linearly projected with a reverse spin along the longitudinal axis of said playing surface such that said wheel generally rolls in contact with said surface first in one direction and then in the reverse direction and either comes to rest within one of said zones or traverses the entire length of said playing surface and returns to its starting point, the desired effect depending on the method selected to award points for each toss.

Abstract: A tool holder has a shank to be coupled to a machine spindle; a driven member adapted to receive therein a tool and having peripheral dents and recesses; a sleeve member for transmitting a torque from the shank to the driven member, the sleeve member having inclined slots and first balls loosely fitted in respective inclined slots; a spring-loaded, cup-shaped member having an inclined wall surface engageable with the first balls; and second balls lodged in respective recesses in the driven member, so as to impede the sliding movement of the cup-shaped member toward the first balls. When a tool receives an unusual rotational resistance during the rotation in the normal direction, then the sleeve member interrupts transmission of a torque to the tool, and in turn continues idling. The rotation in the normal direction, of the tool is resumed by rotating the sleeve member in the reverse direction and then in the normal direction.

Abstract: A toothpick holder and dispenser that is especially adapted for carrying in the pocket of a user includes an elongated container having an open end and cap member covering the open end. Each member is integrally made of plastic material and has rounded corners to avoid damaging the pocket of the user. The container has a cylindrical main compartment for holding a quantity of toothpicks, and also has one circumferential portion of its exterior wall radially enlarged to provide a discharge compartment. The cap member is rotatable between one position in which it fully covers the discharge compartment and another position in which the discharge compartment is exposed for purpose of withdrawing a toothpick therefrom.

Abstract: A tool holder has a bore adapted to receive therein a tool having locking flat surfaces on the shank thereof, and a peripheral wall defining the bore; tangential holes running across the peripheral wall and having an aperture open to the bore; and locking cotters each having an inclined surface and disposed in each tangential hole movably in the axial direction thereof. Displacement of each locking cotter towards the mid portion of the tangential hole causes the inclined surface to press against the flat surface of the shank due to the wedge effect, thereby locking the shank to the peripheral wall. Increasing torque, which acts on the shank, moves the locking cotter in the axial direction to a further extent, thus providing an increased wedge effect, whereby a greatly increased shank retaining force is obtained.

Abstract: An immunoadsorbent in which the specific immunologically reactive protein is polymerized with a halogenated proteinaceous material. The halogenated immunoadsorbent is a fine granular, filterable material having generally stable characteristics.
