Abstract: Centering and wear compensating means for turret bores and the like. Plugs of a suitable resilient, long wearing, self-lubricating material are equiangularly placed in bores of uniform length provided in the wall of a turret bore in which a tool holder is positioned. The plugs are made long enough to be compressed into the bores by the tool holder when the tool holder is centered in the turret bore and are spaced along the turret bore such that engagement of the plugs with the tool holder will be maintained as the tool holder is raised and lowered in the turret bore. The plugs are curved on one end to conform to the tool holder surface and are chamfered to permit easy compressibility as the tool holder is positioned in the turret bore.

Abstract: A bland food supplement which can be used as a filler, extender, or protein binder in a variety of food products is made from water-extracted vegetable pulp such as sugar beet pulp. The pulp is contacted with an aqueous bleaching solution selected from the group consisting of hydrogen peroxide, an alkali metal peroxide, ammonium persulfate, sulfur dioxide, sodium hydrosulfite, sodium chlorite, sodium hypochlorite, chlorine, chlorine dioxide and combinations thereof. The bleached pulp is separated from the bleaching solution, and is then dried to obtain a stable, free-flowing, food supplement comprising about 4% to 8% by weight water, about 7% to 9% crude protein, about 15% to 25% crude fiber, about 60% to 70% nitrogen-free extracts, and about 2.5% to 5% ash.

Abstract: Oil sand is mixed with steam and water in a tumbler to produce a slurry. The slurry is then transferred to the immersed portion of an apertured inclined surface in a water bath. The inclined surface may be in the form of a rotating drum, a tilted rotating dish or an inclined moving endless conveyor belt. The sand particles drop through the apertures and are collected from the base of the bath and discarded. The bitumen moves to the submerged portion of the oleophilic inclined surface and attempts to pass through the apertures; it touches the surface and adheres thereto. The adhering bitumen is collected when the coated surface emerges from the slurry. The process gives a good recovery of a bitumen product which has acceptable quantities of solid and water contamination. The temperature of separation, the need for reagents, and water requirements are reduced in comparison to the prior art. The process can generally be used for separating oleophilic materials from hydrophilic materials.

Abstract: Improved cylinder locking means for a small, single action revolver which is positioned entirely within the body of the revolver and operates with the hammer and hand to release the cylinder during cocking of the hammer and to lock the cylinder against turning during firing of the revolver and when the hammer is in a forward position. A spring biased latch member is pivotally connected between its ends to the frame of the revolver so that one end of the latch is positioned adjacent to the lower side of the cylinder and is adapted to make releasable engagement with the cylinder. The other end of the latch is positioned close to one of the sides of the hammer. An actuating member projects from the hammer or hand and is adapted to strike the underside of the end of the latch during the initial cocking movement of the hammer and pivot the latch to release the cylinder for rotation.

Abstract: Improved means for releasably locking the cylinder of a small, single action revolver in proper rotatable position within the frame of the revolver. A cylinder axis pin is adapted to extend through a first bore in the front portion of the frame, then through a central bore in the cylinder, and into a bore in the rear portion of the frame which is axially aligned with the first bore. A counterbore is provided in the front portion of the frame extending inwardly into the front portion of the frame coaxially with the first bore therein. A lip extends downwardly over the top portion of the counterbore at its open end, i.e., at the front or barrel side of the front portion of the frame.

Abstract: A single action single barreled revolver having an oscillating arm trippet retained in the hammer cavity which interacts with the cylinder latch to rotate the cylinder in battery position or in the alternative allow the firing pin to be positioned in a cylinder notch in the cylinder web between the cylinder chambers thereby locking the cylinder in a safety or non-battery position.

Abstract: Bituminous sand such as oil sand or tar sand is mixed with steam and water in a tumbler to produce a slurry. Oversized particles are removed and the slurry is transferred into a water bath containing a submerged moving, apertured, separator, such as an endless belt having an oleophilic surface and top and bottom flights. The slurry falls through the water onto the top flight of the belt where the bitumen is attracted to the apertured oleophilic surface and adheres thereto. The adhering bitumen is then removed from the belt. Mineral particles in the slurry and the remaining bitumen pass through the apertures of the top flight and fall through the water onto the bottom flight of the belt. The remaining bitumen of the slurry is attracted to the apertured oleophilic surface of the bottom flight and adheres thereto. The adhering bitumen is then removed from the belt.

Abstract: The accuracy of a semi-automatic piston of the locked breech type is improved by tapering each side of the tenon at the rear of the barrel and correspondingly tapering the tenon engaging recess in the slide, thereby assuring that the rear of the barrel is accurately centered at the breech face of the slide and is prevented from moving laterally. The mating surface of the under-barrel lug is contoured such that when the barrel is in battery the slide stop pin bears against the under-barrel lug in such a manner as to cause the barrel to be jam fitted between the slide stop pin and the underside, top surface of the slide thereby preventing any vertical movement.

Abstract: A non-airtight method for determining alveolar ventilation, oxygen uptake and carbon dioxide production which comprises introducing a known amount of an inert gas into the airway of a patient during inspiration and monitoring the expired gas until a steady state is reached wherein the volume of inert gas inhaled is equal to the amount exhaled and subsequently monitoring the expired air containing a known volume of inert gas for inert gas, carbon dioxide and oxygen concentrations.

Abstract: Method and system for sampling and determining chemical substances such as blood gases, in a fluid matrix, such as blood, by bringing the chemical substances into equilibrium with a liquid in a fiber probe, passing the equilibrated liquid to a sensor adjacent the equilibrium region and on into a hollow fiber line enclosed in a calibration chamber. Calibration of the sensors is accomplished by reversing the flow of liquid from the hollow fiber line to the sensors. In the system chemical substances for sensor calibration are provided by an electric proportioner whose output is continuously controlled by the output of the sensors such that the substances proportioned into a fluid in the calibration chamber surrounding the hollow fiber line are substantially the same as the substances within the matrix. The concentration of substances is determined by the output of the sensors and the amount of substances fed from the proportioner to the fluid surrounding the hollow fiber line.

Abstract: An alveolar gas sampling system comprises a catheter adapted for placement in a patient's nostril or in an endotracheal tube and connected to a positive displacement pump through a three way valve. Signal means for detecting onset of inspiration and expiration is mounted at the tip of the catheter and connected to a controller. The positive displacement pump is driven by a reversible stepper motor actuated by the controller during the flow of alveolar air. When the desired amount of alveolar gas has been sampled, the stepper motor is reversed and the position of the valve is switched by the controller causing the alveolar gas collected in the positive displacement pump to be expelled for analysis.
