Abstract: Abstract of the Disclosure The present invention relates to a process for preparing elastic laminates by admixing elastomeric granules with a moisture hardenable polyurethane binder and hardening the binder.  The binder is formulated to have a workable viscosity at room temperature and to avoid crystallization at temperatures above about 0°C.  The binder is the reaction production of polyisocyanates of the diphenyl methane series having at least 20 wt.% of 2,4'-diisocyanatodiphenyl methane and di- and/or trihydroxy polyethers.         The invention also relates to the binder composition itself and a process for preparing it.  The binder has a viscosity of about 1000 to 15,000 cP at 20°C and an NCO con-tent of about 5 to 15 wt.%.  It is prepared at an NCO to OH ratio of about 2:1 to 15:1 and at about 15 to 100°C.

Abstract: Abstract of the Disclosure A sheet of paper is folded by forming a portion of the sheet into S-shape with a folding loop of U-shape and blind loop of opposite curvature, and pressing the opposite sides of the folding loop together in the direc-tion from the open end towards the closed end of the loop, to produce a fold, while the shape of the blind loop is maintained without the sheet becoming folded in the region of this loop.  Apparatus for performing the method is arranged to produce oppositely directed folds alternately along the length of the sheet.  The opposite sides of the folding loop are pressed together by a folding roller which may cooperate with a table to both form the "S" loop and produce the fold, or a second roller which serves to clamp the sheet.  In the latter arrangement a sheet deflector forms the folding loop between the two rollers when they are spaced apart, and in the former arrangement the folding roller is movable against the table, first in one direction to form the S loop and then in the opposite direction to press the folding loop against the table.

Title: High-voltage electric circuit breaker comprising series-connected vacuum interrupter and fluid blast interrupter
Inventor: PORTER JOSEPH W
IPC: H01H33/14
Filed: 1976-03-12
Granted: 1979-07-31
Abstract: ABSTRACT OF THE DISCLOSURE This high voltage circuit breaker comprises a vacuum type interrupter and a fluid-blast type interrupter elec-trically connected in series and arranged to be opened substantially simultaneously so that concurrent arcing occurs in the two interrupters until about the time a natural current zero is reached.  The vacuum interrupter is relied upon the withstand the usual recovery voltage during the initial period after arcing and the fluid-blast interrupter to withstand the recovery voltage after this initial period. Immediately after the circuit has been interrupted by this coaction of the two interrupters, the vacuum interrupter is closed while the fluid blast inter-rupter remains open, thus relieving the vacuum interrupter of continuing voltage appearing across the circuit breaker.

Abstract: METHOD AND APPARATUS FOR ELECTROMECHANICAL RECORDING OF SHORT WAVELENGTH MODULATION IN A METAL MASTER                   Abstract of the Disclosure An unheated cutting stylus is positioned with respect to a metal master in order to cut a groove having a quiescent groove depth less than one micrometer while relative motion is established between the cutting stylus and the metal master.  The cutting stylus is vibrated about the quiescent position thereof in response to a relatively high frequency signal while cutting the groove in order to cut an information track comprising short wavelength modulation (e.g., 0.6 to 1.6 micrometers) of groove depth in the bottom of the groove having a peak-to-peak dimension less than the quiescent groove depth.  The cutting stylus vibration is effected by a piezoelectric element which is mounted directly between a pedestal and the cutting stylus by means of bonding materials.  The pedestal, the piezoelectric element, and the cutting stylus are shaped to form a cutterhead structure having all external surfaces disposed in anti-parallel relationship to each other.

Abstract: ABSTRACT      An electrical igniting unit for use with ignitor devices such as are commonly utilized in electrical cigar lighters, engine ignitor plugs, and the like comprising a heating element, such as a wound spiral of resistance ribbon, carried in an annular metal holder or cup and spanning the mouth or opening thereof.  The inner end of the spiral ribbon is secured to a central metal stud as by crimping or welding it in a slotted head thereof.  Means are provided for securing the outer coil convolution to the rim of the holder or cup by curling inward the rim edge into a tight curl which is laid over on the end portions of the coil convolution whereby a relatively large area of the coil end is tightly and securely pinched under con-tinual pressure to establish a low-resistance, effective me-chanical and electrical connection between the cup and the coil throughout the useful  life of the latter.  The advantage of the present construction over prior devices is that less expense is involved in assembly without sacrifice or reliability or long operating life.

Abstract: "PROCESS FOR PREPARING A HERMETICALLY SEALED                ASSEMBLY"                           ABSTRACT         In the connection and encapsulation of substrates such as cables by covering members such as heat-recoverable sleeves, typically provided with adhesive or mastic linings, the formation upon heating of a desired hermetic seal between the substrate and the covering member is checked by using a device which can detect the excess air pressure which, once the hermetic seal has been made, builds up within a space between the covering member and the substrate.  Preferably this is done by means of a probe which passes between the covering member and the sub-strate into said space and which is connected to a pressure sensitive device such as a balloon or a manometer.  After use, the probe, which is preferably made from a plastics material such as nylon, can be fused or deformed to ensure that the hermetic seal remains intact.

Abstract: AUTOMATIC  INSPECTION AND SORTING SYSTEM    FOR CHIPPED NUCLEAR FUEL PELLETS               ABSTRACT OF THE DISCLOSURE         Nuclear fuel pellets to be inspected for surface flaws, such as chips, are fed onto spaced rotating shafts or rollers which rotate each pellet at a predetermined speed.          A motor driven chain mounted for linear movement beneath the rollers carries outwardly extending arms which contact the ends of pellets on the rollers to advance them axially along the roller length and beneath a distance indicating optical probe.  As each advancing rotating pellet moves under and is optically scanned by the probe, light reflected from inden-tations or flaws, such as chips, in the pellet surface, is converted to signals which correspond to the flawed area and feeds them to a flow-time integrating circuit.  This circuit integrates the sum of surface flaw-time and compares the integrated signal to a standard reference.  Should this exceed the standard, the circuit energizes a solenoid which effects removal of the defective pellet from the system.          The integrating circuit is controlled by a photocell which makes the circuit operative only during the time a pellet is advancing linearly under the probe.
