Abstract: PHASE COMPARING CIRCUIT                 ABSTRACT OF THE DISCLOSURE           A phase comparing circuit can be made as a semiconductor integrated circuit for inclusion in a phase-locked loop for generating a phase-locked output signal synchronized with a pilot signal.  The phase comparing circuit generates first and second reference signals with reverse polarity about their DC level from the pilot signal and first and second base signals having a DC level substantially the same as the DC level of the reference signals.  First and second switching signals with reverse polarity about their DC level are generated from the phase-locked output signal.  A plurality of bipolar transistors are operated by the switching signals alternately to provide first and third current paths and second and fourth current paths connecting the reference and base signals to cancel the DC components therefrom.  A control signal generating circuit provides a control signal current path that connects the first and third current paths and the second and fourth current paths.  The control signal current path includes two control signal output terminals that have two series-connected resistors between them and a bias potential connected between the output terminals.  The control signal at the output terminals represents the difference in phase between the switching and the pilot signals and is used to generate a locking signal for controlling a voltage-controlled oscillator which provides the phase-locked output signal.

Abstract: AN INTERFACE ARRANGEMENT FOR BUFFERING COMMUNICATION INFORMATION BETWEEN A TRANSMITTING AND RECEIVING STAGE     OF A TIME-SPACE-TIME DIGITAL SWITCHING SYSTEM            ABSTRACT OF THE DISCLOSURE         An interface arrangement is shown compensating for timing delays during transmission of communication information between a transmitting and receiving stage of a T-S-T digital switching system.  The arrangement includes a buffer at the receiving stage having first and second storage files.  During a first time slot communication information is written in the first using control signals transmitted along with the communication information while simultaneously the second file is read using a local control signal.  In the subsequent time slot the second file is written to and the first file is read, providing a one time slot slip between the transmitting and receiving stages.

Abstract: ABSTRACT OF THE DISCLOSURE A fixture mounting arrangement is disclosed for effecting very convenient yet secure mounting of fixtures such as soap dishes, tissue holders, towel racks, and the like.  The arrangement includes a one-piece mounting plate which is adapted to be secured to a wall or like supporting surface.  The mounting plate includes one or more mounting portions, and further includes a pair of mounting flanges which extend laterally from a position spaced from the supporting surface generally angularly toward the supporting surface.  The mounting arrangement further includes a retaining portion which is defined by the fixture for cooperation with the mounting plate.  The retaining portion of the fixture defines one or more openings for respectively receiving the one or more mounting portions of the mounting plate, and is configured such that it is positionable between the angularly extending flanges of the plate and the supporting surface.  By this construction, the mounting plate may be very easily and conveniently affixed to the supporting surface, with the fixture thereafter readily mounted on the plate merely by relatively vertically moving the fixture with respect to the mounting plate.  The construction is preferably such that the mounting plate is substantially completely hidden from view after the fixture is mounted thereon, thus providing the overall construction with an attractive and aesthetically pleasing appearance.

Abstract: Abstract of the Disclosure There is disclosed an apparatus and method of recovering a portion of the waste heat produced in a high temperature industrial process,such as a glass melting furnace,where the furnace has at least a pair of regenerators which are alternately used to preheat the combustion air and serve as hot exhaust heat storage means.  The hot exhaust gases from the process are passed through a heat exchanger where the heat is indirectly transferred to the clean compressed air at 100 psi from the compressor of a Brayton cycle energy recovery system with the hot compressed air being expanded in a high performance turbine.  The exhaust from the turbine will be at atmospheric pressure and at a temperature between 750°F and 900°F.  This turbine exhaust is fed to the opposite side regenerator as clean preheated combustion air.  One embodiment is directed to the use of a regenerator that is made up of primary and secondary sections with the exhaust to the heat exchanger being taken from a connection between the sections whereby the glass melting furnace is not effected whether the Brayton cycle system is in operation or the secondary is functioning without the Brayton cycle energy recovery system.

Abstract: SEALED CAVITY SEMICONDUCTOR PRESSURE TRANSDUCERS        AND METHOD OF PRODUCING THE SAME                     ABSTRACT OF THE DISCLOSURE     Sealed cavity structures suitable for use as pressure transducers are formed on a single surface of a semiconductor substrate (20) by, for example, deposit of a polycrystalline silicon layer (32) from silane gas over a relatively large silicon dioxide post (22) and smaller silicon dioxide ridges (27) leading outwardly from the post.  The polysilicon layer is masked and etched to expose the outer edges of the ridges and the entire structure is then immersed in an etchant which etches the silicon dioxide forming the ridges and the post but not the substrate (20) or the deposited polysilicon layer (32).  A cavity structure results in which channels (35) are left in place of the ridges and extend from communication with the atmosphere to the cavity (36) left in place of the post.  The cavity (36) may be sealed off from the external atmosphere by a second vapor deposition of polysilicon or silicon nitride, which fills up and seals off the channels (35), or by exposing the substrate and the structure thereon to an oxidizing ambient which results in growth of silicon dioxide in the channels sufficient to seal off the channels.  Deflection of the membrane spanning the cavity occurring as a result of pressure changes, may be detected, for example, by piezoresistive devices formed on the membrane.
