Abstract: Method and apparatus for coating ball bearings and like spherically shaped objects with a coating composition entrained in a plasma jet, the ball bearings being held captured in an open-sided cage during the coating operation.

Abstract: A device for in-camera marking of photographs, the device including light generating means for exposing an edge position of the film and being selectively movable to various positions within the camera to correspondingly impress mark the various positions on the periphery of the photograph.

Abstract: A closure assembly useful as a means for sealing a pressurized package which includes clamping means shiftable between an open position to receive an open portion of the pressurized package and a closed position to substantially hermetically seal the open portion of the pressurized package. The assembly also includes a retaining means coupled to the clamped means and adapted to be actuated by a force substantially independent of the force associated with the pressurized package whereupon the actuating force will maintain the clamping means in the closed position. Another part of the present closure assembly is an actuation means which is engageable with the retaining means in a manner which supplies the force enabling the retaining means to keep the clamping means in the closed position.

Abstract: This invention is directed to means for inhibiting the apparent shift in the buoyant density of and/or to restore any loss in the buoyant density of the granulocytic white blood cells in a sample of blood, thereby insuring the quality of the separation of lymphocytes and monocytes from granulocytes in a blood sample. The invention comprises contacting a blood sample with a hypertonic fluid containing a low molecular weight organic or inorganic ionic substance and/or with an isotonic or hypertonic fluid containing a high molecular weight organic substance which may contain organic molecules having a lipophilic substituent in their structures and/or with a culture medium for blood cells. An integral part of the invention is an improved blood separation tube utilizing a gel-like substance having a specific gravity between 1.060-1.065 g/cm.sup.3 to significantly enhance the purity of cell separation, while providing acceptable cell yields.

Abstract: The invention relates to a means for cleaning a blade of a window glass wiper of a vehicle. The means comprises at least one wiping edge (6) provided on the outer surface of the glass (2) within the area of motion of the wiper blade (6), whereby the blade (3) slides across the wiping edge when the wiper is on operation. The wiping edge (6) is formed by an edge of a groove provided on the surface of the glass (2). In order to reduce the striking forces acting on the drive mechanism of the wiper and to diminish wearing of the blade itself, the bottom of the groove (11) is provided with a ridge (5) extending longitudinally with respect to the groove essentially in the middle thereof. The upper edge of the ridge is rounded and has a lower position than the outer surface of the glass (2).

Abstract: A mounting structure of a seat for vehicles comprising a standing holder secured to a car floor, a latch member secured to the base of a seat providing with a stopper in the shape of a hook for inserting said holder thereinto and a cushioning material laid onto a car floor for giving elasticity to said latch member upward.

Abstract: An improved lumbar support device for use in a seat back of a vehicle seat is disclosed in which upper and lower lumbar plates are mounted in two stages independent of each other and each of the lumbar plates is connected via a connecting member to an arm engageable with a polyhedral cam, whereby the above-mentioned upper and lower lumbar plates can be moved and operated independently of each other by rotating the polyhedral cam by means of rotation of a handle shaft.
