Abstract: ABSTRACT              CHARGE PUMP SYSTEM FOR NON-VOLATILE RAM       A voltage generating system provides a plurality or difference voltages for powering a dynamic nonvolatile random access memory (NVRAM) chip.  The voltage generating system includes a pair of charge pumps.  Each charge pump is coupled to a controller that senses the voltage level at the output of the charge pump and generates an enabling signal when said voltage is at a predetermined value.  The signal activates a power down circuit which adjusts the charge pump output to a desired voltage level. A programmable oscillator provides the clocking signals for the controller.  The charge pumps and programmable oscillators are periodically deactivated.  As a result, the overall power consumption of the chip is reduced.

Abstract: ABSTRACT A process for determining the relative quantity of low atomic number first material mixed with a higher atomic number second material is described.  A first beam of low energy rays and a second beam of higher energy rays are directed into a sheet of the mixture passing between radiation sources and detectors.  Typically, the first beam is an x-ray beam and the second is a gamma ray beam.  Signals from the detectors in the absence of the sheet are obtained, representing the strengths of the first and second beams.  Thereafter, the portions of the beams transmitted through the sheet are determined using the same detectors.          The relative quantity is then calculated from the values obtained from those two measuring steps.  The invention can be used for measuring the concentration of binder material in glass fiber material.

Abstract: FIBER OPTICS SYSTEM WITH SELF TEST CAPABILITY               ABSTRACT OF THE DISCLOSURE A fire detection system incorporating fiber optics and having a selectively energizable light source for applying light pulses to a fiber optics path and a one-way light transmitting element, such as a dichroic mirror, at the remote end of the fiber optics path for reflecting the pulses back to the detection portion of the system, thus providing a Built In Test Equipment (BITE) test capability in the system.  Instead of a dichroic mirror, a bandpass filter may be used as the light transmitting member.  The bandpass filter is selected to transmit light with wavelengths in the range from about 1.3 to 1.5 microns, in which case the light source is a light emitting diode (LED) emitting light at a wavelength of approximately 0.9 microns. The fiber optics path includes a branch which is coupled to the light source.  This branch may comprise one fiber of a multi-fiber bundle or it may be an auxiliary fiber of a commercially available fiber optics combiner.      An overall system incorporates a plurality of these individual fire detection arrangements in conjunction with a BITE control stage and associated fire alarm.  Any detected fire activates the fire alarm. However, the same fire detection signal, when the system is operated in the BITE test mode, is used by the BITE apparatus to detect failures in the system and identify the portion of the system experiencing the failure.

Abstract: ABSTRACT         For electromagnetically stirring a molten metal in a continuously casting mold, a plurality of linear motor type stirrer units each having a square shape (each side of which is smaller than the height dimension of the mold) are arranged in parallel along the long sides of the mold in such a manner that they are adapted to be changed in orientation by 90°, thereby changing the direction of a stirring flow of the molten steel in-to a given direction.  As a result the surface defect is removed and the quality of the solidification structure is improved, and the application range of the kinds of the steels to be cast can be enlarged.

Abstract: ABSTRACT OF THE DISCLOSURE     A bead construction for a swimming pool cover or swimming pool dome is provided. The bead has a design advantageously suited for retrofit usage on existing swimming pool copings and has locking features which afford substantially improved capability for holding the swimming pool cover or dome secured in a holding groove positioned peripherally around the swim-ming pool. The groove into which the bead is positioned is a part of the swim-ming pool coping that is secured at the top of the pool wall and is the same groove used to hold the swimming pool liner bead. Sufficient gripping force by the bead in the coping channel is provided by the bead configuration to prevent dislodging of the bead by forces pulling on the member attached to the bead. The bead is used on an existing pool coping which has a channel or groove into which the bead of a vinyl liner which covers the swimming pool bottom is positioned. The cover bead of the invention is so constructed and contoured that it is accommodated, together with the bead of the swimming pool liner, within a conventional liner holding channel in the swimming pool coping, i.e. the existing vinyl liner bead holding channel is employed to re-tain the bead of the cover or dome utilizing the bead construction of the invention as well as to hold the conventional liner bead.

Abstract: Abstract of the Disclosure Method of Forming a Windowed Unitary Panel A method of forming a windowed unitary panel having a peripheral edge portion of a windowpane of glazing integrally embedded within a frame of high modulus plastic material includes heating the pane to a preselected temperature prior to its being positioned within a mold.  The peripheral edge portion of the windowpane protrudes into the mold cavity so that the high modulus plastic material forming the frame encapsulates the peripheral edge portion.  This prevents buckling of the windowpane since the preheated windowpane contracts simultaneously with the contraction of the rigid frame as it cools from the molding temperature to ambient.

Abstract: ABSTRACT         The invention relates to a new process for producing titanium IV and zirconium IV pyrophosphates, certain of which are new compounds, and their uses.  The pyrophosphates are prepared by reacting a metal tetraester with phosphorus pentoxide, with or without the addition of an hydroxyl compound, such as an alcohol or a phenol.  Depending on the molar ratio of the components, the compounds produced may contain cyclic or straight chain pyrophosphate groups and alkoxy groups attached to the metallic ion.  In addition to forming new compounds, the process of the invention produces the desired products without difficult-to-separate by-products.  The products of the invention are useful as flame-regardants, antioxidants, coupling agents, impact modifiers and processing aids, and the reaction for their preparation may be represented as follows:                       wherein M is titanium or zirconium; R is a monovalent hydrocarbon group optionally substituted with halogen or oxygen substituents; n is an integer from 1 to 4; m is an integer from 0 to 4; x is an integer from 0 to 3; p is an integer from 0 to 2; q is an integer from 0 to 4; n is greater than or equal to m; n = p + m + q; x m + 2p + q = 4; and when x is greater than 0, q is 0.

Abstract: CONFERENCE CIRCUITS AND METHODS OF OPERATING THEM            Abstract of the Disclosure A conference circuit has a plurality of ports for a corresponding plurality of conferees.  Associated with the ports is a control circuit which determines whether a conferee is active, i.e. talking, or dormant, i.e. listening.  The circuit applies gain to the "active" signals and attenuates the "dormant" signals.  When a listener starts to talk, the circuit switches his port to the "active" mode.  Difficulties arise in determining when a listener becomes active, due to noise and echo with the speech signal.  They are mitigated by comparing the signal from the port with an echo signal estimate derived from the echo return loss for the transmission path associated with the port.  The arrangement takes account of differing echo levels for different transmission paths.                             - i -
