Abstract: ABSTRACT OF THE DISCLOSURE             A heat cap is provided for applying heat to hair on a user's head primarily to a pile or row of hair along the top of the user's head. The heat cap is shaped to conform substantially to the shape of the user's head with the pile of hair thereon so as to apply heat evenly to the hair. The heating coil is disposed in the heat cap only in those areas where heat is desired for the hair and is absent in areas of the heat cap where it is undesirable to apply heat to the head. An adjustable flap on each side of the heat cap enables the size of the cap to be adjusted to fit different users. The adjustable flaps also tend to hold the cap outward away from the ear and lower sides of the head and can be easily opened to enable access to the user's ear while the heat cap is being worn. An electrical thermostat automatically brings the heat cap to an optimal temperature and maintains the temperature during the desired conditioning period. The heat cap is manufactured by cutting a plurality of similarly shaped flat pieces and joining them together along certain corresponding sides.

Abstract: Abstract Apparatus for bunching vegetables and like articles and for placing a closure or tag thereon comprising a plurality of arms (27) for holding and stretching an elastic band and a channel (34) along which is fed a strip (15) of tags.  As the elastic band is stretched taut to a smaller cross section, it intersects the tag and enters the aperture (20) therein.  With relaxation of the elastic band the tag is pulled from the strip and remains an the band to identify the bunched articles.  Bending of the strip by the arm end (45) weakens the strip connecting webs (17) to allow separation of the end tag.

Abstract: PROCESS FOR POLYMERIZATION OF THERMOTROPIC POLYESTERS             ABSTRACT Thermotropic polyesters consisting essen-tially of units derived from diphenols and aromatic dicarboxylic acids are prepared via monocarboxylic acid esters of the diphenols by acidolysis in two steps.  The first step is a melt prepolymerization to form a prepolymer of inherent viscosity in the range of 0.12 to 0.16 dl g-1.  The second step is a melt polymerization by a single pass through a wiped film reactor, in which the film of polymer melt is subjected to a high rate of shear and to a temperature in the range within which the polyester forms an anisotropic melt phase.  The polyester product has an inherent viscosity of at least about 0.5 dl g-1.

Abstract: FIBER OPTIC POLARIZER WITH ERROR SIGNAL FEEDBACK                Abstract of the Disclosure This invention provides apparatus and methods for converting a lightwave of an arbitrary polarization propagating in a single mode optical fiber into a wave having a single linear polarization state.  A polarization couples light of  an  undesired polarization out  of  the fiber,  and  a  photodetector  produces  an  error  signal responsive  to  light  coupled  from the fiber.  Control circuitry  processes the error signal to produce control signals which are input to a polarization of light input to the polarizer to null the error signal.  With the error signal maintained at a minimum value the light input to the polarizer and, hence, the light output therefrom is a wave having only the desired linear polarization.

Abstract: Abstract A check encoder  (11)  for printing of full field MICR codes on checks, includes a check guide (19) and means for sensing the position of the check (25,27) in the check guide (19). A pair of fixed roller assemblies (29,31), coact with a pair of movable roller assemblies (33,35) to grip the check and move the check under the action of a stepper motor (44) to an initial known position. A hammer (87), mounted in a hammer mount (83) and activated by an electrical solenoid (91)  impacts the check against successive selected charac-ters on a font wheel (61) to print the desired MICR code.          Program control mean  (111), in the form of a computer pro-gram,   controls the operation of the check   positioning, check encoding and check moving operations. When the desired MICR code has been printed on the check, the check is moved out of the encoder (11) by means of the fixed and movable roller assemblies (29,31,33 and 35).

Abstract: ABSTRACT:            "Sonobuoy retaining and release apparatus"     Sonobuoy parachute shroud line ends are attach-ed to a cup mounted in and adjacent one end of the sonobuoy outer casing. A heavy ejection spring is beneath the cup for forcibly ejecting the cup outwardly from the one end of the casing. The cup is retained in the casing against the spring force by a pair of partially overlapping elongated plates each having one end releasably inserted in a circumferen-tial slot in the outer casing, the slots being adjacent the casing one end and diametrically opposed. The upper plate is in retentive contact near the other of its ends by a first retainer rod pivoted at one of its ends to the cup bottom surface. The first rod contacts the upper plate near the pivoted rod end and is in retentive contact near its other end with a second retainer rod pivoted at one of its ends to the cup bottom surface. The second rod contacts near its pivoted end the first rod and is in retentive con-tact at its other end with a one shot spring motor driven pin. The location of the points of contact between the plates, the upper plate and the first rod, the first and second rods and the pin and the second rod provide lever arms that result in a very high mechanical advantage between the retaining force of the pin on the second rod and the ejection spring force. Upon ejection, the cup, parachute, and shroud lines are ejected and other sonobuoy components are released from the outer casing.

Said piston has a slightly smaller radius than the spherical chamber so that it moves about near the inside wall of said chamber.  Sealing is provided between the piston and the chamber in the form of at least one sealing strip embedded in a groove in the periphery of the piston.  The cylinder head extends across the diameter of the chamber and has, on at least one of the sides of the shaft and near thereto, an edge extending parallel to said shaft's generatrices.

Abstract: ABSTRACT OF THE DISCLOSURE     There is disclosed herein an orthoscopic ultra-sonic imaging system which includes an acoustic trans-ducer for insonifying an object to be inspected and an improved liquid crystal detector cell for receiving an imaging beam from the insonified object and for displaying a visible image.  An electric, magnetic or acoustic biasing field is applied to the liquid crystal cell for raising the cell to an acousto-optic threshold which permits detec-tion and display of low intensity imaging signals.  The cell surfaces which contact the liquid crystal material are treated so as to preferentially align the liquid crystal molecules for situations where electric or mag-netic field biasing is used.  Preferential alignment means that the longitudinal axis of the molecules are on average parallel to each other as indicated by the bulk director.  Furthermore, when an electric biasing field is employed, the surface treatment to be used is selec-ted in relation to the dielectric properties of the chosen liquid crystal material.  The operation of the system described herein is based upon the effect of liquid crystal/contact surface interaction; liquid crystal/biasing field interaction; and liquid crystal/imaging beam interaction on the ori-entation of the sample director.  Using the improved liquid crystal system, low intensity, acoustic fields [e.g. less than 10-3 w/cm2 (watts per square centimeter)] can be detected and displayed, and the object being ex-amined can be insonified with low intensity ultrasonic beams.

Abstract: Abstract A food processor (20), such as a smokehouse, cooker, dryer or the like, includes a food receiving chamber (22) having left and right ports (24 and 26) closed and opened by air flow control means provided by pivoted perforated louvers (44 and 46).  For rightward horizontal air flow across flat-lying food products, the left set of louvers is closed such that air flow is restricted to passage only through the perforations or orifices (48) as an input port.  The right set of louvers are open to provide lower resistance to and a higher volume of output air flow.  This enables the discharge of the extra volume of water vapor due to moisture evaporating from the food in the chamber and in turn enables uniform air flow circulation and food processing without the accumulation of water vapor and consequent increased humidity in the chamber which would otherwise retard drying.
