Abstract: A bearing lubrication system for turbine apparatus. Lubricating fluid stored in a pressurized oil reservoir is pumped by a main oil pump to the bearings. An oil cooler is provided immediately upstream of the pressurized reservoir to lower the temperature of the fluid stored therein and provided to the bearings. Oil returned from the bearings is drained to a nonpressurized oil collection chamber which supplies the suction of the main oil pump. An emergency gas system is included to insure an independent oil flow capacity in the event of interruption in power to, or failure of, the main oil pump.

Abstract: A method of determining blood viscosity of blood in the body. Venous pressure in a body vein is maintained at a constant pressure. Blood is then withdrawn from the vein at a constant pressure for a time period and the volume of blood withdrawn is determined, to obtain an indication of blood viscosity when in the body. The time period can be constant and the blood volume is then proportional to body blood viscosity. Alternately a predetermined volume of blood is withdrawn and the time period is measured and is proportional to blood viscosity in the body. Preferably a three-way valve is incorporated into a system comprising a needle, syringe and vacuum gauge to enable withdrawal of blood at a predetermined negative pressure so that blood viscosity can be obtained rapidly and inexpensively.

Abstract: A missile and target toy which allows horizontal and vertical manipulation of the path of a missile or arrow and at the same time providing a stationary base from which the arrow is propelled, which allows one handed loading, aiming and firing of a missile. The stationary base comprises an H-shaped structure with an open lateral support bar for the missile and is mounted on and into the ground.

Abstract: A lubricant distributor system including a plurality of piston cylinder lubricant injector units constructed and arranged so that the pistons thereof move in sequence from retracted positions to lubricant displacement positions to expel a given quantity of lubricant from each of the cylinders and then move in sequence from the lubricant displacement positions to the retracted positions, whereby each cylinder except the last is refilled with lubricant from an adjacent cylinder and only the first cylinder discharges lubricant back through a lubricant supply line upon completion of each lubricant cycle.A lubricant injector adapted for sequential operation when used in multiples in a centralized lubrication system.

Abstract: A baseball-like game apparatus includes a playing surface marked to define a triangular area defining a pair of foul lines and a defensive base line. Indicia are located within the triangle to define the placement locations of case or other objects which can be knocked over in a generally T-shaped configuration. The defensive team stands behind the base line and pitches the ball to the batter who attempts to hit the ball with the bat to knock over the cans.

Abstract: Bearing apparatus to position a smooth-surfaced machine member from another member for relative motion of the two members parallel to that surface while permitting small relative motions thereof normally of that surface in response to changes in applied stress pressing the members together normally of that surface comprises a hollow piston sealingly received in a cylindrical cavity in that other member and with its crown to the exterior of the cavity, the piston having a small-bore passage through the crown between its end faces inside and outside the cavity, a compression spring disposed inside the piston and engaged between the underside of the crown and an adjustable abutment on the other member inside the cavity, a pump to deliver hydraulic fluid at a constant time rate to the cavity, and means to regulate the temperature of the fluid so delivered.

Abstract: Lubricant dosing device for double-action, two-conduit central lubricating systems, wherein a housing has therein two piston chambers, an outlet control chamber, two inlets for a pressurized lubricant, and two outlets for predetermined dosed amounts of the lubricant. One chamber is for a control piston and the other for a dosing piston; the longitudinal axes of all three chambers preferably pass through corners of an imaginary triangle perpendicular to the main axis of the housing.

Abstract: A bearing arrangement and lubricant supply system for rotating machines, illustrated as embodied in a vacuum pump of the liquid vortex type comprises a stationary hollow shaft on which is mounted the rotor of the pump. The rotor includes a hollow shaft concentrically mounted about the stationary shaft on bearings near the ends thereof. Oil under pressure is supplied to the interior of the stationary shaft and from there to the annular space between the shafts. The stationary shaft is provided with inlet and discharge portions and the oil from the annular space is discharged through the discharge portion. The high pressure is maintained within the bearing spacer and throughout the spacer with the shafts. The rotor in effect floats on the lubricant and the volume of oil under pressure acts somewhat as a shock absorber and minimizes shock or unbalance occurring during operation of the pump.

Abstract: A shuttlecock skirt has an array of diverging stems, whose ends are at the convergent end of the skirt, joined together in an end-ring. The outer end of the end-ring is closed to form a member of `U` -- shaped transverse cross-section. This member is provided with a nose-stem, projecting away from the skirt, for anchoring a striking cap. In a preferred embodiment a radial extension, e.g. disc, is attached to the nose-stem and various preferred dimensions for the end-ring are defined.

Abstract: A game apparatus which includes a vertically extending pole having a helical groove therealong and a spring wire having a helical portion disposed in the groove.

Abstract: The invention provides for playing equipment comprising a ball and a racquet. The racquet includes a length of sturdy tubular material shaped into a shaft, a handle at one end of the shaft and an annular head at the other end of the shaft, and a loose net secured to the head to extend across the opening defined in the head and forming a concave ball-receiving playing web in which a ball which is smaller than the opening defined in the head is receivable. Basic maneuvers such as picking up the ball, catching it and throwing it can be executed with the racquet.

Abstract: A system for lubricating flexible clutches and couplings while they are in motion. There are two shafts provided, one that is driving and another that is driven, connected to one-another by means of a flexible clutch which may be formed from two forked arms held flexibly to one another by means of small stud shafts. These shafts, in the process of operation, have a way to become wornout, and it is rather important that lubricating grease may be delivered to them to decrease friction, Grease is delivered to a stationary housing within which is rotatably mounted a circular disk. The disk is connected to the drive shaft and to the driven shaft. Grease passes from the housing into the disk and is then conducted to the bearing points of the clutch.

Abstract: This device consists primarily of an electric vacuum pump which includes a discharge line and an input line secured to a three-way valve having handle for selection. A line attached to the valve of the device is secured to a fitting threadably secured within the oil pan of the engine and another line secured to the valve is secured by a fitting to the oil filter, the valve serving to completely eliminate the oil and dirt from the oil pan while also removing the oil from the filter.
