A combination urine meter and collection receptacle for measurement of liquid urine volume formed from a pair of plastic sheet panels, preferably flexible at least in part, closed along their peripheries, and having dividing wall means therein defining a lower volume first compartment and a higher volume second compartment. An inlet is provided into the first compartment, wherein liquid urine introduced thereinto may be measured by suitable indicia and thereafter transferred to the higher volume...

Blood collection and preservation units comprising containers with anticoagulant solutions therein are improved by incorporating dihydroxyacetone (DHA) in the anti-coagulant solutions, either alone or in combination with one or more other additives, such as adenine, inosine, and sodium pyruvate. The quality of fresh blood stored in the improved units is significantly better, and the quality can be maintained for longer storage times.

The coupling between a high speed electrically powered vehicle and an overhead catenary wire current distribution system is enhanced by providing compensation separately for low amplitude dynamic displacements of a wire contacting current collector which occur at different frequencies.

A data collection and utilization system having a portable data key entry and memory unit and a portable recorder, both of which operably fit into a console system. The key entry unit and the recorder may be coupled together by a cable and used apart from the console for entering numeric or alphabetic data into memory and for taking data from memory to the recorder. The two units may be readily electrically coupled to the console system by a series of pin connections which make contact when the ...

A syringe type sampling valve wherein delivery is achieved by rapid drive forward of syringe piston and collection of sample is achieved by the cam controlled with drawal of the piston. The cam assures slow, usually uniform filling rate of the syringe barrel.

The coupling between a high speed electrically powered vehicle and an overhead catenary wire current distribution system is enhanced by elastic coupling means which parallels and thus provides for uniformity of movement of oppositely disposed ends of a support portion of a pantograph-bow collector linkage system when the inclination of the system to the horizontal exceeds a predetermined limit.

There is provided a system for collecting dust during the filling of a mixer with cementitious materials. Basic to the system is a hopper having a conduit for transport of materials to the mixer, a seal which surrounds the outlet of the conduit and engages the inlet of the mixer and an exhaust duct having an inlet which faces the interior of the mixer and outlet for connection to a source of suction. Application of suction to the exhaust duct during filling of the mixer removes the dust generate...

A vacuum operated body fluid collection bottle having an insert container of receptacle which is calibrated to receive accurately measurable, small quantities of body fluid collected within the bottle. Such insert includes overflow means whereby quantities in excess of a predetermined amount can overflow into the interior of the outside container. The insert container, in a preferred form of the invention, is positioned by means of a flange disposed against a shoulder provided within the interio...

In a uterine aspiration apparatus, a plastic collection bag is used inside a single rigid collection bottle. The bag is of a design that it does not collapse when the aspiration vacuum is applied to the bottle. The bag collects the produces of the operation and thus (1) keeps the rigid bottle clean for the next operation, and (2) conveniently stores the aspirated material for future laboratory analysis or recording purposes.

A rear loader for refuse collection vehicles. The rear loader includes a housing with an opening through which refuse is deposited in a hopper. A movable packer plate in the housing moves in opposition to the bottom of the hopper to partially compress the material and subsequently to convey the material through a discharge opening into the body of the vehicle. The packer plate in the housing also cooperates with an ejector plate in the body to further compress the refuse contained within the bod...
