  • Patent number: 3999538
    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 Blood is then withdrawn from the vein at a constant pressure for a time period and the volume of blood withdrawn is determined, to obtain an indication of blood viscosity when in the body.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 Alternately a predetermined volume of blood is withdrawn and the time period is measured and is proportional to blood viscosity in the body.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.

  • Patent number: 3993164
    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.

  • Patent number: 3991855
    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.

  • Patent number: 3990704
    Abstract: A target game of the type wherein a target image is movingly projected upon a screen for simulated shooting by a gun assembly. The target game generally includes a target projecting assembly for randomly exhibiting a moving target onto the screen and for giving an indication of a successful hit. A gun assembly is movably mounted over the target projecting assembly for selectively exhibiting a hit area on the screen and for causing the target projecting assembly to indicate a hit, along with a drive assembly. The target projecting assembly includes a first projector having a film holder which is movable between a "normal" position wherein a target image is presented for projection and a "hit" position wherein an explosion image is presented for projection. The target projecting assembly also includes a hit actuating member associated with the film holder to move the holder from its normal position to its hit position.
