Abstract: ADJUSTABLE RACKET FRAME AND THE PRODUCTION METHOD                ABSTRACT OF THE DISCLOSURE     The basic racket frame is comprised of an oval head, a yoke merging into a throat and a solid or a hollow shaft which is formed from a single length of collimated filaments preferably graphite fibers,  known as a roving impregnated with a thermosetting resin.  This roving is prewound onto a separable spool, transferred into a compression type of mold where  it  is  subjected  to  a  sustained  balanced  maximum tension and cured under heat and pressure.  Alternatively, the roving is directly machine wound onto a machine-rotated combination  mandrel mold  device.   The  single  length  of roving  is  first wound  into  a first loop portion on the mandrel-mold defining the oval-shaped head portion.  Rota-tion is stopped and a permanent cellular core encased by a resin  impregnated  fiber  fabric together with a removable core rod are placed securely within the mandrel-mold.  A pin is fixed in the mold spaced from the head portion.  Winding is continued using the same length of fiber roving to form more elongated turns about the pin and further encompassing the  head  and  the  core  materials.   When  the winding  is completed,  the  finishing end  is  securely knotted to the starting end at the pin location to define a dual-portioned solidly  closed  loop  which  is  tensioned  throughout  to  a maximum degree.

Abstract: ABSTRACT A multicuvette rotor for use in a centrifugal analyzer defines a circumferential array of elongated radially extending cuvettes   The rotor includes a one-piece body member of material that is transparent at analytical wavelengths and has a planar upper surface and defines a circumferential array of elongated cuvette recesses, and a one-piece cover member of similarly transparent material that has a planar lower surface parallel to the planar upper surface of the body member. A continuous seal extends around each cuvette recess between the planar upper and lower surfaces to define the circumferential array of analytical cuvettes.  Each elongated cuvette defines a first chamber for receiving a first constituent with a loading port in the cover member through which the first constituent is introduced into the first chamber region, a second chamber region for receiving a second constituent with a loading port in the cover member through which the second constituent is introduced into the second chamber region, divider structure between the first and second chamber regions provides a transfer passage between the first and second chamber regions through which the first constituent may be flowed into the second chamber region for forming a reaction product with the second constituent, and structure defining an analysis region adjacent the radially outer wall of the cuvette where the resulting reaction product is subjected to analysis.  Extending along the top of each sidewall of each cuvette between the loading ports of the first and second chamber regions is barrier structure that fills the junction between the cover and body members so that there is no capillary channel at that junction and premature mixing of the constituents due to wicking movement of a constituent stored in one of the chamber regions to the other chamber region along that junction is inhibited.

Abstract: ABSTRACT OF THE DISCLOSURE               The sterilizing device includes a heating chamber having a reservoir containing a substantially inert, vaporizable liquid having a boiling point sufficiently high to kill microorganisms unsafe for humans.  The sterilizing liquid is heated to boiling by a heater submerged therein.  The articles to be sterilized are placed in a perforated tray located in the chamber above the reservoir and are contacted by a  blanket of substantially saturated vapors of the sterilizing liquid.  A temperature controller turns the heater off and on in response to the vapor blanket rising to and falling below a predetermined level above the tray.  A counter counting the number of electrical impulses or cycles thereafter transmitted to the heater turns off the heater after a predetermined number of such cycles and a fan or similar cooling means is energized to cool the chamber and condense the vapors.  Vapors entrained in the air displaced from the chamber by the rising vapor blanket are either removed by a filter arrangement or collected along with the air in an inflatable member and returned to the chamber after completion of the sterilizing cycle.

Abstract: IN-LINE FIBER OPTIC MEMORY Abstract of the Disclosure A fiber optic recirculating memory comprises a splice-free length of optical fiber which forms a loop that is optically closed by means of a fiber optic coupler.  The coupler couples an optical signal input pulse to the loop for  circulation  therein,  and  outputs  a portion of  the signal pulse on each circulation to provide a series of output pulses.   A pump source  is  included  to pump the fiber loop with a pump signal having sufficient intensity to cause stimulated Raman scattering in the fiber loop, and thereby cause amplification of the circulating signal pulse.         The    fiber    characteristics,    coupler characteristics,  and pump power are selected to yield a Raman  gain  which  compensates  for  the  total  round-trip losses in the fiber loop, so as to provide an output pulse train of constant amplitude pulses.  The invention may be implemented  utilizing  either  a  standard  coupler  or  a multiplexing   coupler.      The  multiplexing   coupler advantageously  permits  independent  selection  of  the coupling  ratios  for  the  pump  signal  and  signal  pulse, thereby allowing these coupling ratios to be selected for minimum loop loss and maximum pumping efficiency.
