Abstract: ABSTRACT OF THE DISCLOSURE           An apparatus and method for molding polycarbonate lenses is disclosed in which the lenses are formed in a single injection molding operation.  Polycarbonate is injected into a cavity between two movable dies which are forced apart by the injected polycarbonate.  These dies are then urged together forcing a portion of the injected polycarbonate back through the same port through which the polycarbonate was injected.  The finished lens does not have the knit line normally associated with injection molded lenses.

Abstract: ABSTRACT          There is disclosed an electromagnetic transducer for the transmission and reception of ultrasonic waves in the touchless testing of metal workpieces, particularly made of steel, in the shape of sheet and strip material. The transducer is arranged for continuous testing, particularly as applied to continuously advancing material, by wavelength spectroscopy and particularly modal spectroscopy of received ultrasonic waves. To this end, the transducer comprises a pair of transducer segments each of which has a set of mutually parallel conductor tracks formed on a substantialy planar printed circuit board in which the frequencies and wavelengths for each segment can be preset in a matrix logic circuit having a short time sequence. The conductor tracks comprise windings arranged to be connected for operation through a set of switching elements in such a manner as to produce in various switching states of the switching elements a plurality of wavelengths for each frequency. The wavelengths being proportionally related to each other by small integral numbers.

Abstract: PROCESS FOR ELECTROLYTICALLY REMOVING METAL DEPOSIT             FROM A NON-PLATED SURFACE OF A SINGLE.     SURFACE-PLATED METAL STRIP                  ABSTRACT OF THE DISCLOSURE    In a process for electrolytically removing metal deposit from a non-plated surface of a single surface-plated metal strip, by bringing, within an electrolytic liquid, a single surface-plated metal strip which serves as an anode plate, into a location at which the non-plated surface of the anode single surface-plated metal strip faces in parallel to and is spaced from a cathode plate, and by applying a principal voltage between the anode metal strip and said cathode plate to electro-lytically remove metal deposit from the non-plated surface; whereby undesirable stripping of portions of the plated metal layer in side edge portions of the plated surface of the metal strip is prevented by arranging supplementary anode plates within the electro-lytic liquid in such a manner that the supplementary anode plates face in parallel to and are spaced from side edge portions of the plated surface of the anode metal strip, and then, while the principal voltage is applied between the anode metal strip and the cathode plate, a supplementary voltage is applied between the supplementary anode plates and the metal strip, the electric potential of each supplementary anode plate being higher than that of the metal strip.

Abstract: TITLE       A METHOD FOR GENERATING STROKE-VECTOR CHARACTERS                  FOR USE IN A DISPLAY SYSTEM            ABSTRACT OF THE DISCLOSURE          A novel method is disclosed for use in an electronic raster-scan display system, for generating characters using a stroke-vector technique.  An incoming data signal defines the type of character to be displayed, the character field dimensions, the character drawing point, and any character rotation or reflection.  Using that part of the data signal that defines the character type as a memory address, a character micro-program is retrieved containing a plurality of encoded binary valued stroke-drawing directives.  These directives are instructions detailing how to generate all of the shape depen-dent attributes for a series of chain related stroke-vectors that define the overall shape of a character to be displayed.  The en-coded drawing directives are decoded and sequentially applied to a set of initial values that define an initial virtual stroke-vector, and thereby generating all of the character shape dependent stroke attributes for a series of chain related stroke-vectors that define a character shape.  Once defined each stroke-vector is scaled so that the generated character cell size corresponds to the character field dimensions defined by the external data signal.  Lastly a logical pel may be generated and added to the individual stroke-vectors before the connected stroke-vectors are projected onto the display screen at the character drawing point.

Abstract: Abstract of the Disclosure In  a method  for  detecting  the  presence  or  absence  of  a specific   restriction   site   in   a  nucleic   acid   sequence   an oligonucleotide probe complementary to one strand of the nucleic acid sequence spanning said restriction site is synthesized. The probe is labeled at the end nearer the restriction site.   The nucleic acid is hybridized  to  the  probe  and a  blocking  oligomer may  be  added,  if necessary, to prevent non-specific binding of the probe.   Subsequent digestion with a restriction enzyme cleaves those oligomers that have hybridized to the nucleic acid and reformed the restriction site.  The resulting cut and uncut labeled oligomers are separated and detected based on the type of probe label.   The  described  method  may  be  used  to  detect  sickle  cell anemia.

Abstract: ABSTRACT       A free piston engine includes speed control means which provide a wide range of engine speed control for selective connection and use of the engine with any one of a number of different types of energy absorbing devices.  The desired control is achieved by use of two bounce chambers (18p and 18n) and a double-acting bounce piston unit (16) specifically located at an intermediate position along the axis of reciprocation of the piston rod assembly of such an engine, i.e. between a power piston (15) at one end of the piston rod and a connecting means at the other piston rod end for driving connection of the piston rod assembly with a movable member (e.g. reciprocating compressor piston (34) or reciprocating electric generator member) of the selected energy absorbing device.     The control means further includes at least one pair of vari-ably adjustable bounce chamber pressure control valves (23 and 24), one for each bounce chamber.  Each control valve of such one pair provides for and controls a direct connection of its respective bounce chamber to ambient atmospheric air outside the bounce chamber. The controls further include sensing means (37) responsive to changes in demands on or operation of the selected energy absorbing device for variably and substantially simultaneously adjusting each control valve of such one pair and thereby similarly changing (i.e. both upwardly or both downwardly) the respective bounce chamber w working pressures.  Other bounce pressure control features are also described.

Abstract: ABSTRACT     The subject invention concerns a process for stabilizing intact or ruptured microbial cells having active enzymes associated therewith.  Speci-fically exemplified is a process for stabilizing glucose isomerase producing cells of a microorganism belonging to the genus Ampullariella.  In the inven-tion process the whole or ruptured microbial cells are contacted with a partially modified cationic polyelectrolyte, e.g., a partially modified polyamine, to stabilize and flocculate the cells.  It is critical that the polyelectrolyte be partially modified; a fully modified or non-modified polyelectrolyte will not give the surprising beneficial results of the invention process.  The flocculated cells are further stabilized by encapsulation with a partially modified cationic polyelectrolyte.  The encapsulation can be done prior to or after the flocculated cells are cross-linked.  The net effect is manifested by a dramatic increase in the half-life of the enzyme, thus leading to a more effective use of the immobilized enzyme.
