Title: Solar energy collector module system
Inventor: PEI YU K
IPC: F24J2/52
Filed: 1979-07-27
Granted: 1980-07-29
Abstract: ABSTRACT OF THE INVENTION       The invention disclosed is a solar energy collector apparatus having several double-wall glass tubular elements connected on opposite sides of an elongated manifold to form a module.  The elements are sealed in oppositely facing metal cups and inside the opposite elements is a cross supply tube.          The cups in a module are series connected by conduits for flow of a liquid through the collectors.  Along the manifold are two header pipes respectively connected to the cups for introducing liquid to the collectors for series flow and for receiving heated liquid flowed through them.  The headers also connect a series of modules and the system utilizing the solar heated liquid.  The cups, header pipes and intercon-necting conduits are enclosed in an insulation jacket of foamed plastic, e.g. polyurethane.  The manifold includes support brackets for mounting the apparatus in spaced drain-age position above a supporting surface having a solar exposure.          The outer ends of the tubular collectors are supported on an end loading device which firmly supports the element above the support surface and retains the element in its manifold cup when under hydraulic pressure.

Abstract: PBX FIELD DISPLAY          ABSTRACT OF THE DISCLOSURE          A PABX control circuitry housing which functions both as a housing for the circuitry and also as an indicator console, and can be mounted either on a wall or a desk top.          To achieve a narrow, inobtrusive cabinet which can be used in this way, printed circuit boards are mounted parallel to the front of the housing.  Indicators such as light emitting diodes (LEDs) are mounted along one edge of each of the printed circuit boards retained within the housing.  The printed circuit boards are retained on successively stepped ledges, which causes the edges containing the LEDs on each of the boards to be visible from the front of the housing.          A darkened, preferably translucent window in the housing allows the operator to view the LEDs.  A silk screened or other imprint on the window provides the operator an indication of the meaning of the lit LEDs.

Abstract: ABSTRACT OF THE DISCLOSURE         A cutting recording apparatus in which a cutting stylus connected with a piezoelectric ceramic member for generating a mechanical vibration in response to an electrical signal to be recorded is secured to the free end of a cantilever with the other end thereof supported on a cantilever support.  The cutting stylus is elastically pressed against a recording medium which is driven to rotate.  The component of change of pressure between the cutting stylus and the recording medium which pressure changes in accordance with the unevenness of the surface of the recording medium is made to be offset by the component of change of the lifting force of the cutting stylus which force changes in accordance with the change of the cutting angle of the cutting stylus changing in accordance with the unevenness of the surface of the recording medium, thus forming a contour or a signal contour corresponding to the electrical signal sequentially at a predetermined depth from the surface of the recording medium regardless of the unevenness of the recording medium.

Abstract: RARE EARTH-MANGANESE OXIDATION CATALYSTS      AND PROCESS OF PRODUCING                       ABSTRACT         Alkali metal delta manganese dioxide hydrate, which is obtained as a by-product in the industrial oxidation of organics by KMnO4 is subjected to ion exchange reaction with rare earth ions of the ceria subgroup (viz. cerium, lanthanum, etc.).  By employing favorable temperature and pH conditions, a reaction product can be produced containing as little as 0.03 moles of alkali metal per mole of manganese, and up to one mole of ceria rare earth per six moles of manganese.  The separated product is prepared for catalytic use in the form of dried porous pellets.  The resulting oxidation catalyst has high efficiency, long life, and optimum activity at reasonable temperatures.  The catalyst can be used advanta-geously for applications such as the oxidation and deodoriza-tion of exhaust gases from paint drying ovens.

Abstract: SPECIFICATION OF   DALE H. BONE     FOR DRILL MONITOR SYSTEM                      ABSTRACT OF THE DISCLOSURE There is disclosed herein an apparatus for automatic monitoring of numerous high speed drill spindles on a numerically controlled drilling machine for purposes of immediate detection of the absence of drilling by a particular spindle because of a broken drill bit. The apparatus detects the absence of drilling, interrupts the automatic cycle of the drilling machine and alerts the operator. Power dissipation in each drill spindle motor is compared just prior to entry of the drill bit into the workpiece and after entry if any. If power dissipation increases above a predetermined threshhold level for all spindles, no interrupt is generated. If power dissipation does not increase in one or more spindle motors, comparator circuits alert a digital processor which interrupts automatic operation of the drilling machine and alerts the operator. Such a system eliminates the expense and error of human visual monitoring and generation of expensive scrap improperly processed before discovery of the broken bit.

Abstract: Abstract A process is descried for converting heavy hydrocarbon materials, e.g. bitumen pitch, to hydrocarbon gases and liquids, carbon monoxide and hydrogen. The process com-prises spraying a preheated heavy hydrocarbon feedstock into contact with a preheated bifunctional particulate catalyst, said catalyst having (a) a pyrolysis or cracking reaction component and (b) a carbon-steam and carbon-oxygen reaction component, the spraying causing the heavy hydrocarbon material to coat the exterior surface of the catalyst particles. A pyrolysis or cracking reaction is continued whereby the heavy hydrocarbon coating is conver-ted to an adhering char and hydrocarbon vapours. The hydrocarbon vapours are separated from the char-coated catalyst particles and these particles are then contacted with steam and an oxidizing medium to convert the char to carbon monoxide, carbon dioxide and hydrogen gas. These gases are separated and the remaining catalyst is recycled.

Abstract: 1                    PHN. 9370.      ABSTRACT:           A system for transmitting n-level data signals by means of an angle-modulated carrier having a constant amplitude and a continuous phase.  The constant ampli-tude enables amplification in non-linear transmitter out-put stages.  Associated with the n-levels are k(k > n) phase variations in accordance with such a rule, depend-ing on preceding phase variations, that the spectrum of the angle-modulated signal becomes narrower.  In a symbol interval the phase of the carrier changes by an amount from the sequence extending from -(k-1) .pi./n to (k+1) .pi./n in increments of 2 .pi./n.  The receiver is formed by a differential n-phase receiver.  The system is used inter alia for radio transmission of digital information.

Abstract: A.P. Schloth-1 ABSTRACT OF THE DISCLOSURE    A double-acting hydraulic cylinder has a piston disposed therein for dividing the cylinder into first and second portions with a single piston rod extend-ing from one end of the cylinder.  Each end of the hydraulic cylinder is connected to a hydraulic reservoir that is hermetically sealed and pressurized through the unique use of a metal bellows which pressurizes the hydraulic fluid.  A pressure-compensated, variable orifice control valve is dis-posed between each end of the hydraulic cylinder and the reservoir for limiting the rate of fluid flow from the cylinder to the reservoir to a substantially constant value independent of external loads ap-plied to the piston rod.  The variable orifice in-creases in size with cylinder depressurization and thereby provides for a rapid release of internal residual hydraulic pressures after high dynamic loads are experienced.  When used as a shock suppressor for piping systems unrestricted pipe motion is permitted in response to movement caused by thermal expansion or contraction, and pipe motion is suppressed by limiting the velocity of the pipes relative to a supporting structure during shock and oscillating load conditions.  A lock-up indicator is used to pro-vide an indication of high resistance of the device due to a lock-up condition.  Radiation resistant seals are utilized throughout the device to provide for long maintenance-free periods required for nuclear applications.     April 24, 1979
