Title: Proximity focused streak tube and streak camera using  the same
Inventor: LIEBER ALBERT J
IPC: H04N5/257
Filed: 1978-09-18
Granted: 1981-12-01
Abstract: Abstract of the Disclosure Proximity focused streak tube having a photocathode for converting photon images into photoelectrons.  A phosphorous screen is provided for receiving the photo-electrons.  The photocathode and the phosphorous screen define a longitudinal tube axis.  A passive channel plate is provided which has a plurality of parallel bores therein. The channel plate is disposed in relatively close proximity to the photocathode and so that the bores are inclined at an angle with respect to longitudinal tube axis so as to minimize feedthrough of visible photons.  A source of voltage is connected between the photocathode and the passive channel plate causing the photoelectrons to be extracted from the photocathode and to pass through the bores in the channel plate.  First and second spaced apart beamselectrodes are disposed between the channel plate and the phosphorous screen.  Another voltage source is utilized for applying a voltage differential between the beam electrodes to cause the photoelectrons to move in the direction across the screen.  The beam electrodes are arranged asymmetrically of the tube axis to compensate for the inclination of the channel plate with respect to the tube axis.  The passive channel plate is very flat so that the voltage differential which is applied between the photocathode and the channel plate can be relatively high to provide a high electron field.  A fiber optic input is utilized which is also inclined at anaangle with respect to the longitudinal tube axis so that the fiber optic bundles are in alignment with the bores provided in the faceplate.  A fiber optic output window is provided which carries the phosphorous screen and provides the luminous streaked images which are photo-graphed.

Abstract: APPLICATION OF:  TIMOTHY J. MORSCHECK     FOR:  AUTOMATIC TRANSMISSION                     A B S T R A C T           Disclosed is a power shift transmission having two input shafts, an output shaft, two countershafts which are first synchronized and clutched with either of the input shafts, and then alternately clutched to the output shaft.  Each countershaft rotatably supports a ratio gear driven by one of the input shafts, a ratio gear driven by the other input shaft, and a drive gear for driving the output shaft.  A reverse gear is rotatably supported by one of the countershafts.  A double acting synchronizer is disposed between the two ratio gears on each counter-shaft for synchronizing and clutching either of the ratio gears to the countershaft.  A hydraulically actuated friction clutch is disposed adjacent the drive gear on each countershaft for clutching the countershaft to the driven gear.  One of the input shafts is a torque converter driven shaft; this shaft drives the ratio gears which are first and second speeds and the reverse gear.  The other input shaft is a torque converter bypass shaft; this shaft drives the ratio gears which are third and fourth speeds.  The transmission utilizes helical gears and the helical angle direction of the ratio and drive gears on the countershafts are such that axial forces on the contact teeth of the gears impart bending stresses on the countershaft which subtract from bending stresses on the shaft caused by radial forces on the contacting teeth of the gears.

Abstract: Title of the Invention LARGE CAPACITY COMBINATION MAGAZINE AND SHEET FEEDER FOR COPYING MACHINES     Abstract of the Disclosure My invention comprises a large capacity combined magazine and sheet feeder for copying machines, in which the sheet being fed is brought to feeding level by a spring-powered mechanical servomechanism.  The assembly is adapted to be substituted for a small capacity cassette on an existing copy machine and to employ the power and logic of the existing machine to feed sheets from the large capacity assembly in proper synchronized relationship.  This is accomplished by a power take-of from the copy machine with which the improved magazine is being used, which power take-off can be installed without altering the original , machine.  The large capacity unit then feeds sheets to the copy machine as if the original small capacity cassette were being used.  The magazine is adapted to handle sheets of various lengths on which copies are to be made.  The action of the lifting springs is damped by an inertial damper which controls the rate of upward movement of the paper supporting platform which is constrained to move parallel to itself by a parallel motion linkage.

Abstract: METHOD OF AND APPARATUS FOR BIOCIDAL STERILIZATION  USING CYCLIC SUBATMOSPHERIC PRESSURE CONDITIONING                 ABSTRACT OF THE DISCLOSURE         Conditioning of goods for subsequent sterilization with a biocidal agent in a sealable chamber includes removal of air, and moistening and heating the goods to the desired temperature levels.  Controlled evacuation of the chamber and coordinated admission of conditioning vapor into the chamber provides cyclic variations in chamber pressure between pre-selected subatmospheric pressures to subject goods in the chamber to a plurality of cyclic subatmospheric pressure pulses.  The time required for the cyclic pressure variations is responsive to load characteristics, including heat and moisture absorption characteristics of the goods being condi-tioned, and is independent of prescribed times or direct measurement of load temperature.  The subatmospheric pressure levels are selected based on the temperature-pressure rela-tionship of the conditioning vapor so that chamber temperature during cyclic pulsing does not exceed the desired steriliza-tion temperature.

Abstract: Abstract A roll holder and dispenser for rolls of webbed material such as used for toilet paper or towels com-prising a container having a first aperture where rolls are inserted and a second aperture from where a web of roll material can be withdrawn.  The container is made relatively theft proof by an inwardly angled flange.  The flange is situated near the first aperture, and allows a roll to be inserted but makes it difficult for a roll to be withdrawn.  Near the second aperture there is a second flange used for separating the upper stored rolls from the bottom usable roll.  A side aperture is situated in a side wall or at the same level as the flange.  When it is desired to pull a roll down from the storage position it is only necessary to insert a finger or thumb through the aperture and engage the center core of the roll, and pull it downward past the flange to the usable position at the bottom end of the container.  By having the usable roll resting on the bottom end there is sufficient friction provided to allow a user to easily remove the webbed material while at the same time making it difficult to extract material in excessive lengths.

Abstract: 15.5.79                    1                     PHN.9387 ABSTRACT "Method of synchronizing a quadphase receiver and clock synchronization device for carrying out the method"                  The invention relates to a method for the clock synchronization of a receiver for demodulating a quadphase coded data signal and to a clock synchroniza-tion device for carrying out the method.                 Four elementary signal forms can be distinguished in a quadphase coded data signal. Each ele-mentary signal form represents two-bit information, these two bits being transmitted in a first and a second half bit interval and these two bits being transmitted in the inverted form in a third and a fourth half bit interval. The information in the second interval is consequently highly correlated with the information in the first bit interval.                 The four quadphase code words have been chosen from the sixteen code words which can be formed with four bits and that in such a manner that only two-bit information is transmitted with these four bits. This is achieved by making the first and the second bit of the quadphase code word equal to the two-bit information of the signal to be coded and by making the third and the fourth bit equal to the inverse value of the two-bit information. In the method according to the invention the first bit is compared (correlated) with the third bit and the second bit with  the fourth bit: a high degree of correlation indicates 15.5.79                 2                    PHN.9387 that synchronization has been obtained and a low degree indicates absence of synchronization.                 The invention is used in the field of optical and magnetic recording and in the field of data transmission over physical pairs of wires.
