Abstract: A rotary machine particularly intended for use as a pump comprises a two-lobe lenticular rotor rotatably disposed within a pump chamber defined by an annular wall with an inner surface having at least in part a cardioidal configuration. A rectangular drive plate on a shaft is disposed within an elongated drive slot in the rotor while a circular guide disc fixed on an end wall of the pump casing extends into a second elongated guide slot in the rotor. The second guide slot is perpendicular to the first slot so that, during operation, the rotor effectively reciprocates and rotates relative to the guide disc. If desired, two such circular guide discs can be provided, one on each end wall of the pump casing, for reciprocation and rotation relative to two such second guide slots in opposite faces of the rotor.

Abstract: A collector of a blood sample from a body member comprising a hollow container which is closed at both ends and has a hypodermic needle projecting from one of the ends and extending into the interior of the container. An arcuate disc of a frangible, inert material is sealingly positioned within the container to divide it into two compartments, one containing a blood culturing medium, the other air. An elongated tube engages the interior end of the needle and passes through the disc into the air chamber. When the wall of the container is deflected inwardly to expel the air to create a negative pressure condition within the container, the disc is broken thus allowing the blood drawn into the container when the wall is released to mix with the medium.

Abstract: The present invention provides a central elongate highly-absorptive pad element having side panels extending laterally therefrom. The side panels may be formed as an integral part of the invention or may be formed separately and secured to the longitudinal edges of the central element. The lines of common juncture between the central element and the side panels provides flexibility so that the side panels may be folded over the upper surface of the central element for packaging and may be folded toward the back side of the central element when the invention is used. The central element and the side elements have a fluid-impervious backing upon which is placed a thin layer of flexible adhesive which will not penetrate the absorbent materials placed thereon. The central element has a highly-absorptive pad means whereas the absorptive means on the side panels may be minimal. The backing element of the central portion of the invention contains a strip of adhesive covered by a protective tape until use.

Abstract: An improved telescopic boom for a truck mounted hoist in which at least the middle telescoping section of the boom is fabricated from I-section structural steel having a central web, and upper and lower flanges, the flanges having inwardly facing surfaces lying in angled planes which are not normal to the plane of the web, and in which the trolley and fixed portion of the boom are fabricated of any other suitable structural material, and having at least two sets of identical rimmed wheels, one set mounted directly on the fixed section, and the other set mounted directly on the trolley, without the use of tilting arms, the two sets of wheels riding in opposite sides of the I-section material of the telescopic intermediate section, with the tread of the wheels carrying the load and with the rims providing lateral guidance thereby dispensing both with the mounting arms and with the lateral guide rollers.

Abstract: A multi-function hydraulic tool especially intended for use in automobile servicing operations comprises a hydraulic cylinder housing a piston. At least one arm is secured to the outside of the cylinder and projects axially therefrom. A seating is secured to the arm forwardly of the open end of the cylinder so as to support one member when axial force is applied by the piston to a different cooperating member so as to cause relative movement of such members. The tool can be used for a variety of purposes, for example, for removing a bearing from a shaft and its arm is usefully releasably secured to the cylinder.

Abstract: The present invention is an improved extension for use with socket wrenches. The invention comprises a generally cylindrical housing having an axial hollow into which is inserted a light source and batteries. The ratchet or handle end of the extension contains a biased switch which is closed when the handle or ratchet is inserted into that end. The socket receiving end has a socket retaining ball formed from a metal strip which is attached to the outer surface of the socket receiving end in a recess. The open end of the bore in the extension is closed by a plastic disc. The extension may contain one, two, or more batteries depending upon its length.

Abstract: An air flow reverser apparatus for use in association with an air flow system having air supply and return port means, said apparatus comprising a main supply duct, and a main return duct, said ducts being connectable to said respective supply and return port means of said air flow system, at least two branch supply ducts communicating with said main supply duct, at least two branch return ducts communicating with said main return duct, supply damper means for selectively shutting off at least one of said branch supply ducts, while leaving at least one said branch supply duct open, return damper means for selectively shutting off at least one of said branch return ducts while leaving at least one said branch return duct open, and means interconnecting said supply and return damper means whereby when a selected one of said branch supply ducts is closed, a selected one of said branch return ducts is open, and power operated means for moving the same from one position to another simultaneously.

Abstract: The portable fish catcher comprises a fish trap of a type employing gill netting which is attached at top and bottom respectively to a pair of rings which may be oval, triangular, rectilinear, round, or other geometrical configuration. Additional steadiness of the catcher is provided by flexible lines interconnecting the two rings which lines are placed on the inside of the gill netting. The top ring has attached thereto a float so that when the catcher is placed in the water, the weight of the rings extends the catcher downwardly. Bait is suspended within the catcher by attachment to the tilt ring or to the float. The float attached to the top ring has means thereon for attaching a line so that the catcher may be retrieved. The weight of the rings causes the catcher to be extended to the full length of the interconnecting lines. When the catcher is not in use, it collapses to the height of the diameter of the two rings plus the float.
