Abstract: ABSTRACT A method of rolling metal workpiece in a rolling mill consisting of rolling stands or pinch rolls, and more than one high reduction rolling stand disposed successively.  The roll gap of the workrolls of the rolling stand at the rear side is set so that the corresponding contact angle ?? (?? = tan -1 (cos .alpha. x tan ?) wherein a denotes contact angle between the workrolls in the bottom of the rolls groove and the workpiece, and .alpha. denotes inclined angle of the groove) is bigger than tan -1 µ (µ denotes a frictlon coefficient between the workpiece and the workrolls at the biting time) and also is smaller than tan -1 µ' (µ' denotes a friction coefficient between the workpiece and the workrolls when the workplece is completely bitten between the workrolls and the rolling is in progress).  The workpiece is fed to the rolling stand of the rear side by the rolling stand or the pinch roll of the front side; and compression stress (below the yield stress at the rolling time) is produced in that part of the workpiece which is located between the rolling stand or pinch roll at the front side and the rolling stand by the feeding of the workpiece, to assist biting the workpiece between the workrolls of the rolling stand of the rear side.  The peripheral speed of the rolls of the workrolls/and or the pinch roll is adjusted after the tip portion of the workpiece is completely bitten between the workrolls of the rolling stand of the rear side while the workrolls remain with the previously set roll gap, and rolling is continued in the condition where the stress of the direction along the rolling line between the rolling stand or pinch roll of the front side is removed.  The workpiece can thus be rolled with the high reduction of area which cannot be achieved by conventional regular rolling mills.

Abstract: ABSTRACT OF THE DISCLOSURE An improved sealing system for the vacuum chamber of a machine for processing a workpiece with a beam of charged particles is disclosed.  The workpiece has an elongate processing zone which is movable relative to the vacuum chamber passing through an entrance section in a sealing zone into the vacuum chamber and exiting therefrom through an exit section of the sealing zone.  The sealing zone surrounds a beam exit opening of the vacuum chamber and provides a seal against the workpiece face while permitting rel-ative movement.  To improve the seal, the width of the sealing zone is en-larged either at the entrance section or at the exit section or both and various other improvements such as flexible lip seals are proposed.  Also various ways of dealing with the problem of adequately sealing the weld bead are proposed.  For example, an elongate slot in the seal may be provided or a wire brush arrangement which flexibly engages the weld bead may be used.

Abstract: ABSTRACT OF THE DISCLOSURE An array of read-only  memory cells is formed from a plurality of insulated gate field-effect transistors. Information may be programmed into individual transistors within the array by application of selected potentials to the connecting lines of the array.   An individual cell is programmed by causing some of the electrons flowing between the source and drain to acquire sufficient energy to be injected into and trapped in the insulating material separating the channel from the gate electrode.   The trapped electrons cause a change in the current-voltage characteristics of the transistor, which may be detected during reading of the memory cell most easily by reversing the polarity of the source and the drain   Embodiments of such an array are shown and may be utilized as a ROM, PROM or EPROM.

Abstract: ABSTRACT OF THE DISCLOSURE           A new form of nerve growth factor having a molecular weight of about 116,000 and which is stable in dilute aqueous solutions is obtained from mouse submandibular gland or mouse saliva.  An extract of mouse submandibular gland or mouse sal-iva is subjected to ion-exchange chromatography to recover a component of the gland or saliva rich in the nerve growth fac-tor and containing proteinaceous material which does not degrade the nerve growth factor.  The pure nerve growth factor is ob-tained by subjecting the component rich in nerve growth factor to at least one additional chromatography step, usually two to four, to recover pure nerve growth factor having a molecular weight of about 116,000.         The invention described herein was made in the course of work under a grant or award from the Department of Health, Education and Welfare.

Abstract: SOLAR ENERGY COLLECTOR                  ABSTRACT OF THE DISCLOSURE           The solar heat collector includes an enclosure having a solar energy transmitting cover member and a solar energy absorbing base member. Within the enclosure, structure is provided, connected to a fluid inlet, for causing a stream or film of fluid to flow along the interior surface of the cover member.  The same structure may be used to impart a separate flow of fluid along the energy absorbing base member.  The cover member is oriented to prevent the gravitational forces on the fluid stream, flowing along the interior surface of the cover member, from over-coming the adhesion forces between the stream and the interior surface of the cover member.  This stream removes condensation from the cover member as it captures heat therefrom.  The stream may be created by spraying fluid on the interior surface of the cover member or by a fluid dispensing member having a fluid outlet adjacent the interior surface of the cover.  Means for distributing the fluid across the interior surface as same flows therealong may also be provided.

Abstract: Abstract of the Disclosure An oil storage reservoir has a fluid flow passage which returns fluid to the main transmission reservoir. The storage reservoir is supplied with fluid by the transmission control system and the amount of fluid that returns to the main reservoir from the storage reservoir is controlled by a thermally responsive valve mechanism such that, as the fluid temperature increases, the flow passage is reduced so that the level of oil in the storage reservoir is increased.  Thus, the change in fluid volume, due to temperature change, is accommodated by the storage tank as controlled by the thermally responsive valve.

Abstract: SOl 229 DEFLECTION CONTROL APPARATUS FOR A  BEAM INDEX COLOR CATHODE RAY TUBE  ABSTRACT OF THE DISCLOSURE         Deflection control apparatus is disclosed for a beam index color television receiver of the type which includes a cathode ray tube adapted to display a video picture in response to a received color television signal.          The beam index cathode ray tube is provided with index stripes which are scanned by the electron beam as the beam scans a raster across the display screen of the tube.  A detector detects when the respective index stripes are scanned by the beam so as to produce an index signal, the frequency of which varies from a predetermined frequency value when the scanning speed of the beam varies.  An oscillator generates an oscillating signal that is synchronized with the index signal, and a phase locked loop, which includes a comparator for comparing the index signal to the oscillating signal so as to produce a control signal as a function of the difference therebetween, adjusts the frequency of the oscillating signal in accordance with that control signal.  The television receiver also includes a switching arrangement which is responsive to the oscillating signal to switch color information signals for the purpose of modulating the beam.  The deflection control apparatus includes a deflection device for controlling the deflection of the beam; and a deflection signal generator responsive to the control signal produced by the phase-locked loop for supplying deflection control signals to the deflection device so as to vary the deflecting speed of the beam and thereby maintain a substantially constant scanning speed thereof.
