Title: Continuous nonshielding strip protective wrapping for buried pipe
Inventor: NEE ROBERT M
IPC: B32B11/04
Filed: 1990-09-13
Granted: 1994-10-25
Abstract: A  continuous  strip  non-shielding  and  pressure-resistant wrapping material for protecting buried metallic pipe is disclosed. The wrapping material comprises a continuous layer of cold-flowable rubberized bitumen bonded to a substantially non-elastic porous support backing with a release film positioned on the exposed face of the bitumen to protect the bitumen prior to application.  When applied to a metallic pipe, the protective bitumen is secured to and held in place by the non-elastic support backing and thus cannot sag away from the pipe.  The porous support backing provides potential electric current paths through each pore so that cathodic protection can be effectively utilized to protect against corrosion in even the smallest holiday in the bitumen layer.

Title: Device for and method of measurement of an angle of incidence of a luminous beam
Inventor: RHEME CHARLES
IPC: G01S17/46
Filed: 1991-05-22
Granted: 1998-08-04
Abstract: For measuring an angle of incidence of a luminous beam, one employs a polarized luminous beam which is brought to pass through a birefringent plate followed by an analysing polarizer, in order to obtain a succession of fringes of interference, and one analyses by means of an appropriate detector and an electronic circuit the spacings between the crests of said fringes, said spacings being a direct function of the angle to be measured.  One can utilize a measuring device of an angle of incidence for measuring the distance between said device and a reflecting surface of the object to be measured, by determining for a certain position of the object a spacing of reference between the crests of the fringes of interference and by measuring the variations of the spacings as a function of the position of the object, in order to display them in units of length.  With such a method, it is possible to measure the angles of incidence or distances with a device of small dimensions and with a measuring range broader than before and with an increased precision.

Title: Fiber optic gyro
Inventor: ISHIGAMI MOTOHIRO
IPC: G01P3/36
Filed: 1991-12-23
Granted: 1997-06-17
Abstract: Between clockwise and counterclockwise light beams having spent a time ? in propagating through a loop-shaped optical transmission line are provided phase differences .pi./2 rad alternately at intervals of a time k? in accordance with a biasing signal.  Light of interference between the clockwise and counterclockwise light beams is converted to an electric signal corresponding to the intensity of the interference light.  A step value signal for phase negative feedback is derived from a synchronously detected output and the step value is accumulated by an accumulator.  When the accumulated output exceeds a threshold value corresponding to 2m.pi. rad, the accumulator outputs the overflow value as the accumulated result and, at the same time, outputs an overflow signal and an overflow sign signal representing its polarity.  The accumulated output is converted by a D/A converter to an analog signal, by which an optical phase modulator is driven.  A control signal generator outputs a 0 when the overflow signal is zero, outputs -1 when supplied with a positive overflow signal, and outputs +1 when supplied with a negative overflow signal. The output of the control signal generator is applied to a multiplier.  The level difference between the outputs of a synchronous detector before and after the biasing signal is changed over at the k? time intervals is detected by a conversion error detector.  The detected output is applied to the multiplier, wherein it is multiplied by the control signal from the control signal generator.  The multiplied output is integrated by an integrator and the integrated output is used to control the conversion gain of the D/A converter by a negative feedback, thereby compensating for a change in the conversion gain of the optical phase modulator.

Title: Predictive coding device capable of coding image data signals without a discontinuity among blocks
Inventor: OHTA MUTSUMI
IPC: H04N19/176
Filed: 1992-01-30
Granted: 1997-12-09
Abstract: In a predictive coding device responding to a sequence of image data signals representative of picture elements to produce a sequence of coded output signals, a plurality of provisional error signals are calculated for each picture element from the image data signals and different provisional prediction signals sent from predictors and are given weights in multipliers from a weight decision circuit in consideration of a position of each picture element to produce weighted error signals.          The weighted error signals are summed up into a first sum signal by a first adder circuit and thereafter processed into the coded output signals and local decoded signals which are sent to the predictors.  The predictors may carry out either different prediction from one another for each picture element or identical prediction in relation to different blocks.  Alternatively, a motion vector which is calculated for each block may be smoothed in consideration of the other motion vectors calculated for adjacent blocks on motion-compensated prediction.          Thus, weighted means values are calculated as the weighted error signals and/or smoothed motion vector at every picture element so as to mitigate a discontinuity among the blocks.

Abstract: A magneto-optical disk has a recording layer whereon recorded bits are formed by the magnetic field modulation method  and  a  readout   layer  whose  axis  of   easy magnetization is parallel to the recording layer at room temperature,  and  varies  to  be  perpendicular  to  the recording layer within a predetermined temperature range between  room  temperature  and  the  Curie  temperature.          During  reproduction  of  the  recorded  bits  the  first semiconductor laser emits a heating-use light beam to form the  first  light  spot  on  the  readout  layer.   Thus,  a ring-shaped  region  corresponding  to  the  predetermined temperature   range   exhibits   perpendicular   magnetic anisotropy and  the  recorded bits  are  copied  from the recording layer onto the ring-shaped region.  As the first light spot is shifted, the ring-shaped region as a readout window of recorded bits is also shifted.   Further,  the second semiconductor laser emits a reproduction-use light beam such that the second light spot is formed on the readout layer to overlap the first light spot at a rear portion  thereof.   Consequently,  only  one  recorded  bit copied onto the rear portion of the ring-shaped region can be reproduced; therefore, high-quality reproduced signals can  be  obtained  from  the  magneto-optical  disk  having information recorded with high density.

Granted: 2002-04-23
Abstract: In the method of the present invention for making a non-fat cream cheese product, a fermented skim milk retentate is introduced into a mixing tank provided with agitation means. The skim milk retentate is agitated and transferred through a recirculating loop as dry cottage cheese curd and an emulsifying salt are added to the mixing tank. Agitation and recirculation are continued for a period of time sufficient to provide a dispersion of the dry cottage cheese curd and emulsifying salt homogeneously throughout the retentate. Heating of the dispersion is then started by injecting steam into the dispersion as it passes through the recirculating loop. While the temperature of the dispersion is within the range of from about 70° F. to about 150° F., non-fat dry milk is added to the dispersion. Agitation and heating is continued until the dispersion temperature is within the range of from about 140. degree. F. to about 165° F.      Xanthan gum, as the first gum of a stabilizing system, is then added to the mixing tank. Agitation and heating is continued until the dispersion temperature is in the range of from about 165° F. to about 190. degree. F. The steam is shut off and salt, sugar and carrageenan, as the second gum of a stabilizer system, are added to the mixing tank. Agitation is continued for a period of from about 1 to about 4 minutes to provide a non-fat cream cheese mix. The cream cheese mix is then homogenized to provide a non-fat cream cheese product.
