Title: Antibody against acid phosphatase isoenzymes  for detection of prostatic cancer

Abstract: ABSTRACT OF THE DISCLOSURE An immunochemical method for detecting prostatic acid phosphatases has been developed which is useful in clinical laboratory testing for prostate cancer and in enzyme and protein determinations.  An isoenzymatically homogeneous prostatic acid phosphatase antigen is prepared by isolating purified acid phosphatase from cancerous human prostate tissue.  The antigen stimulates the production of diagnostic antibodies which are highly specific, do not cross-react with other acid phosphatase isoenzymes and can be used in countercurrent immuno-electrophoresis (showing a sensitivity of 0.4 I.U. of enzyme activity or 20 ng/ml enzyme protein) and in a solid phase fluorescent immunoassay (showing a sensitivity of 60 pg/ml enzyme protein with excitation of the alpha-napthol hydrolysis product at 340 nm and emission at 465 nm)  with no false positives and few false negatives in diagnosing cancer of the prostate.

Abstract: ABSTRACT       A control unit for controlling operation of a plurality of audio teleconference terminals includes a plurality of inputs for connection to respective teleconference terminals to receive speech signals therefrom, and variable impedance devices having high and low impedance conditions connecting each input to a plurality of outputs, each output being associated with a particular input.  The arrangement is such that when a variable impedance device is in a low impedance condition signals can be fed from the input associated with that variable impedance device to all outputs other than the one with which it is associated.  The control unit responds to speech signals from said inputs to control the variable impedance devices so that at least two of the inputs at which speech signals are received can be coupled to the outputs such that at least two terminals can be connected in open loop teleconference and any remaining terminals can receive the conference.

Abstract: METHOD AND APPARATUS FOR REDUCING AIR  DRAG ON TRUCK TYPE WHEELED VEHICLES     Abstract of the Disclosure A tubular air screen producing device is mountable on a draft vehicle adapted to tow a trailing vehicle therebehind and has an air inlet end in the direction of towing and an air outlet end for discharging a screen of air toward the horizontal and vertical edges of the front end of the trailing vehicle.  The outlet end of the device is of smaller area than the inlet end and is configured to direct a screen of air toward the trailing vehicle edges at a velocity higher than the velocity of air relative to the draft vehicle moving at a given velocity relative to ground.  The high velocity air screen streamlines the area be-tween the draft and trailing vehicles and shrouds the space there-between, so as to minimize air turbulence in the space and along the top and side walls of the trailing vehicle.  Thus, air drag is reduced and fuel economy is increased in connection with the towing of a trailing vehicle.

Abstract: IMPROVED LENS EDGING APPARATUS            Abstract of the Disclosure An apparatus for edging the periphery of an ophthalmic lens to a predetermined outline or edge configuration, is characterized by a work holder for supporting and rotating a lens while moving an edge of the lens against a grinding surface of a grinding wheel. During grinding the lens is engaged with only a portion of the surface, and to prevent a groove from being formed in the surface a sensor automatically detects the highest point on the surface and controls movement of the work holder to move the lens thereagainst.  In consequence, the wheel wears evenly, it retains a substantially cylindrical shape, all portions of its grinding surface are effectively used in grinding lenses, and formation of a groove in its surface is prevented, whereby the wheel does not require retruing or reshaping and its useful life is significantly increased.

Abstract: RCA 73,936 ABSTRACT OF THE DISCLOSURE          A record caddy, suitable for use with a video disc player, includes a sleeve and a record retaining spine removably located therein.  Disposed on the spine are latch members for releasably locking the spine to the sleeve.  Latch defeat fingers, disposed in the player, are wedged between the respective spine latch members and interior portions of the sleeve during an occupied caddy arrival at a fully inserted position in the player, so that the spine latch members are deflected in a manner freeing the spine from the sleeve.  The player is further equipped with spine gripper members for locking the spine to the player during such caddy arrival, whereby subsequent sleeve withdrawal removes the spine and the accompanying record from the sleeve for retention in player.  To retrieve the retained record, an empty sleeve is inserted into the player.  Insertion of the sleeve into the player for record retrieval causes deflection of the latch defeat fingers, which deflection, in turn, results in displacement of the spine gripper members in a manner disengaging the spine from the player, whereby the spine and the associated record are removed from the player during subsequent caddy withdrawal.
