Abstract: ABSTRACT OF THE DISCLOSURE           A support that may be either in the form of a cushion or chair in which the portion thereof in contact with a specific user conforms to the body contour of the user, with the support being of hollow construction and filled with a resilient material such as a foamed poly-merized resin or the like.  The exterior surfaces of the support are enveloped in an envelope of a resilient material.  The support is formed by having a user sit upon a bag of pliable sheet material, which bag is partially filled with a flowable granular material.  A partial vacuum is applied to the interior of the bag to maintain it in the configuration to which it was deformed by the weight of the user.  The bag is now coated with a liquid or paste material that solidifies.  After solidification the granu-lar material or the complete bag is removed through a small opening in the bag, or in the solidified material surrounding the bag and the interior of the bag or the cavity formed by the solidified material has a liquid resin mixed with a catalyst introduced therein in a sufficient quantity to fill the interior of the bag when it polymeri-zes into a foamed resin.  The solidified envelope is removed from the foamed resin filled bag or cavity.  The bag or resulting form is now coated with a film of inert material such as resilient rubber or other substance.  The finished support may be used in either a stationary position or mounted on a mobile unit.

Abstract: ABSTRACT           A tapered roller bearing has a porous rib ring against which the large ends of its tapered rollers bear so that the ring prevents the rollers from being ex-pelled.  The rib ring is formed from porous powdered steel that has been compacted to a density of about 70% to 85% of theoretical and then sintered and machined.  To expose the pores at the surface against which the large ends of the rollers bear, the machined rib ring is etched. Finally, the rib ring is impregnated with oil.  Should the bearing lose its normal supply of lubrication, the critical region of contact between the abutment face on the rib ring and the large ends of the rollers will never-theless be adequately lubricated for a reasonable time by lubricant which escapes from the pores of the rib ring. The cage of the bearing is piloted by the rib ring and by a ring-like cup insert that is formed in the same manner as the rib ring.

Abstract: ROTOR HEAD ASSEMBLY FOR DECANTING CENTRIFUGE             ABSTRACT           A rotor head assembly for a decanting centrifuge parti-cularly useful for clinical laboratory procedures requiring the washing and packing of red cells or other particles.  An electro-magnet having upper and lower planar pole faces rotates to drive the removable rotor head assembly and, during the decant cycle, holds a plurality of magnetically-attractable tube carriers in substantially vertical positions against its planar pole faces so that supernatant liquid is centrifugally discharged from the open upper ends of the tubes.  Each tube carrier comprises a tube-holding member and a contact member, both of which have their upper end portions pivotally suspended from a support ring which is provided by the rotor assembly and which is coaxial with the rotatable magnet.  The planar surfaces of the contact members engage the planar pole faces when the centrifuge is at rest and also when the electromagnet is energized and the rotor assembly is rotated to decant the liquid contents of the centrifuge tubes.  Each tube-holding member has two outer side walls which meet along converging planes so that such walls will engage a centrifuge tube along a pair of spaced parallel lines during centrifuge operation, thereby permitting centrifuge tubes of different selected outside dimensions to be supported within the open-topped cavity of such tube-holding member.

An instrument lead (9) which is connected to the objects is arranged in series with a voltage detector (8) which is disconnectable.  The voltage detector, in turn, delivers a second output voltage which is dependent on the potential difference.  The transforming circuit (7) delivering a third output voltage dependent on the first and second output voltages is also operatively associated with the equalizer.  The adjustment cable thus has a predetermined resistance value.

Abstract: ABSTRACT OF THE DISCLOSURE    To diagnose diseases in patients, a protein com-plex, RhC, is prepared from horse serum by precipi-tating a white powder from the serum at a pH of 5.5 and processing to remove lipids  at: a  pH of 8.2 using Tris-HCl as the buffer.  It includes two components bound together to provide a molecular weight of 280,000 and having characteristics of a rheumatoid factor and a Clq-like subcomponent of the complement.  The protein complex is incubated with human serum or plasma and then precipitated by dialysis against a high pH buffer (.05 M Tris-HCl pH 8.2).  When precipitated, it co-precipitates the immune complexes from the human blood serum without substantial monomeric immunoglobulin  to quantitatively isolate immune complexes from serum.          Immunological assays then determine how much immune complex and what kind were in the serum.

Abstract: Abstract of the Disclosure Speed Sensing Apparatus A sensing apparatus (10) determines motion of a movable element (24) by detecting fluctuations in magnetic flux density.  These fluctuations are caused by, for example, the teeth on a gear (34), where rotation of the gear (34) sequentially presents each of the teeth and a corresponding recess in close proximity with the sensor (18).  The flux density is consequently altered at a frequency directly related to the rotational speed of the gear (34).  Optimizing the system requires a high signal to noise ratio, thus the air gap between the gear (34) and apparatus (10) must be established at a minimum valve.  Eccentricity of the gear (34), as well as actual radial movement of the gear (34), are accommodated by the use of a plunger element (14) which is axially movable within a first body (12) in response to contact with the gear (34).  A coiled spring (26) annularly disposed about the plunger (14) in an endless configuration engage the plunger (14) and an inner surface (22) of the body (12) to provide a frictional force of a magnitude sufficient to maintain the plunger (14) at a selected position and allow movement in response to actual contact between the apparatus (10) and the gear (34) which prevents damage to the plunger (14) and establishes a minimum axial air gap.  Alternately, a segmented spring (30) is connected to the plunger (14) and contacts the inner surface (22) of the body (12).
