Abstract: RETAINER CLIP AND SYNTHETIC RESIN BOX COMBINATION                Abstract of the Disclosure A spring fastener of generally V-shaped configuration and including a first, substantially monoplanar leg joined to a second substantially monoplanar leg through a bend portion defining an actue angle of from about 43° to about 48°.  The second leg defines a circular aperture therethrough, and the first leg has a tongue pressed out of a central portion thereof, and projecting toward said second leg at an acute angle to said first leg. The tongue projects a distance from the plane of the first leg, as measured normal to that plane, which is from about one-half  to about two-thirds of the total distance of projection of said bend portion from the plane of the first leg, also as measured normal to the plane of said first leg.     The invention also includes and relates to fasteners of the type described in combination with a synthetic resin box which has an open side.  The box carries a pair of the fasteners by having the described first leg of each fastener pressed into an accommodating slot in the box.  The box further defines an elongated passageway adjacent each of the slots and extending parallel to the slot and the first leg of the respective fastener.  The second leg of each fastener extends across the respective adjacent passageway at an acute angle to the axis of the respective passageway, and has the centrally located circular aperture therethrough aligned with the passageway axis.

Abstract: ABSTRACT OF THE DISCLOSURE           A drum support apparatus including outboard and inboard hubs having outer surfaces adapted for interface fitting with the inside surface of a drum. The hubs while being supported on a shaft that is cantilevered from a frame, provide support for the drum in the form of a plurality of spaced equidistant lobes located on their outer surfaces. The lobes reduce the load required to properly seat the drum against the hubs and thereby decreases the possibility of drum run-out by reducing the contact area when the interface fit of the drum/hub combination occurs. The shaft is supported at its outboard end by a removable support bracket.

Abstract: ABSTRACT OF THE DISCLOSURE    Disclosed is an overrunning clutch particularly adapted for "holdback", stand-by drive and "creep" drive applications.  A one-way clutch means, preferably in the form of a sprag clutch provides selec-tive drive between a normally driven member and a normally passive member.  The "passive" member may be retained against any rotation or may be driven at any speed less than that of the normally driven member.  In the illustrated embodiment the normally driven member com-prises a sleeve adapted to accept a shaft.  The sleeve is drivingly connected to the outer race of the one-way clutch.  The inner race of the overrunning clutch is fixed to a housing for the assembly and serves as the passive drive member.  Means are provided thereon for connection to a stationary member or an auxiliary drive.  The passive member is supported on the normally driven member by a pair of bearing means one on either side of the one-way clutch.  One bearing means is supported on the exterior of the normally driven means and one is supported within said means.

A part of the shear plate is provided with hair-entrance apertures and projects from the holder, whilst at the circumference the holder is provided with an adjustable skin-tautenting device.  The adjustable skin-tautening device enables the skin to be tautened to a greater or smaller extent, 80 that the risk of grazing is reduced and the hairs are oriented more transversely to the skin, which promotes the shaving action.  However, the skin-tautening device is located at the circumference of the holder and has no effect on for example that area of the skin which is situated between two or three cutting units.  In order to eliminate this drawback a construction is proposed in accordance with which an outwardly raised portion of the holder is disposed between two cutting units.

Abstract: Abstract of the Disclosure This invention relates to a method for isolating platelets, lymphocytes, and monocytes from anticoagulated blood.  The method involves centrifuging at high force a sample of uncoagulated blood with a water-insoluble thixo-tropic gel-like material having a specific gravity between 1.065-1.077g/cc for a length of time sufficient to cause the gel-like material to form a barrier between the platelets, lymphocytes, monocytes, and plasma fraction of the blood and the heavier blood cells.  Thereafter, the plasma is withdrawn and the platelets, lymphocytes, and monocytes removed from above the barrier in a buffer solution.  Where desired, the platelets can be separated from the lymphocytes and monocytes utilizing a similar process but wherein the water-insoluble thixotropic gel-like material has a specific gravity of less than about 1.055g/cc.
