Abstract: MAGNETOMETER CIRCUIT FOR MEASURING THE    PERIOD OF BEAT FREQUENCY MAXIMA     ABSTRACT    A conventional magnetometer produces an output signal (10) which comprises a series of pulses (12, 14, 16).  Each of these pulses has a beat frequency maximum.  These pulses are input to a comparator (50) which makes a comparison to a threshold voltage V0 to produce a bi-level detected signal at a line (62).          The detected signal is input to an integrator (52) which produces a series of pulses (78, 80, 82) corresponding respectively with the magnetometer output signal pulses (12, 14, 16).  The two states of the detected signal corresponding to positive and negative integration.  The time period for the positive integration is proportional to the beat frequency maximum time width period for the corresponding magnetometer output signal pulse.  Thus the integrated pulses (78, 80, 82) have an amplitude which is a measure of the maxima time width periods for the corresponding magnetometer signal pulses.

Abstract: INTERLEAVED SET-ASSOCIATIVE MEMORY            Abstract In a processing system comprising a main memory for storing blocks of four contiguous words of information, a cache memory for storing selected ones of the blocks, and a two-word wide bus for transferring words from the main memory to the cache, the cache memory is implemented in two memory parts as a two-way interleaved two-way set-associative memory.  One memory part implements odd words of one cache set and even words of the other cache set, while the other memory part implements even words of the one cache set and odd words of the other cache set. Storage locations of the memory parts are grouped into at least four levels with each level having a location from each of the memory parts and each of the cache sets.  The cache receives a block over the bus in two pairs of contiguous words.  The cache memory is updated with both words of a word pair simultaneously.  The pairs of words are each stored simultaneously into locations of one of either of the cache sets, each word into a location of a different memory part and of a different level.  Cache hit check is performed on all locations of a level simultaneously.  Simultaneously with the hit check, all locations of the checked level are accessed simultaneously.

Abstract: ABSTRACT            The disclosure describes an image processing apparatus in which an image stored in a source area in an image memory area is processed and stored in a destination area in the image memory area.  The apparatus determines whether the destination area overlaps on the source area to generate a first response signal indicating the occurrence of the overlap, or a second response signal indicating the non-occurrence of the overlap.  If non-occurrence, the image in the source area is processed as a single image block.  If the destination area overlaps on the source area, the image in the source area is divided into plural sub-image blocks and priority is assigned to the sub-image blocks.  Then, the sub-image blocks are processed in accordance with the priority.

The plastics film is directly adhered to one of the glass sheets by a thin adhesive layer and to the other of the glass sheets by a layer of adhesive which has structural properties and is of substantial thickness compared to that of the film.  Thus the thick structural adhesive film provides  structural  reinforcement  of  the resultant laminate, and this adhesive and its thickness are chosen to provide the desired laminate strength which is thus not determined by the intermediate plastics film.  Hence the latter can be chosen independently of its strength and may be a thin film selected for other desired properties.

Abstract: ABSTRACT OF THE DISCLOSURE         A  multiple  phase electronic  inverter  circuit includes a transistor bridge output circuit having a pair of series connected transistors in each output phase leg adapted to be connected between a pair of conductors for supplying direct current to opposite ends of the phase leg with a connection point between the transistors of each phase  leg  serving as  an output power pole.  A waveform pattern generator generates a transistor switching pattern which  causes  the  transistors  to  alternate  between  two complementary operating modes such that one transistor in each phase leg functions in a commutation mode when and the other  transistor  in  that  phase  leg  functions  in  a non-commutation mode.  By switching between the two operat-ing  modes,  saturation  of  controlled  current  feedback transformers in the base drive circuit of each transistor is prevented.

Abstract: ABSTRACT OF THE DISCLOSURE         A method for the measurement of capacitances, in par-ticular of low capacitances, utilizes measurement electronics which includes a measurement oscillator whose output frequency is a function of the capacitance to be connected to the input termi-nals of a circuit determining the frequency of such oscillator. In the method, two reference capacitances are used, whose elec-trical values are placed within the range of measurement and which are connected, being alternately exchanged with the capaci-tance or capacitances to be measured, to the measurement oscilla-tor while making use of a switching arrangement.  Two external auxiliary references are used in the method.  The auxiliary ref-erence signals obtained from the auxiliary references are com-pared with the corresponding output signals of the measurement electronics, derived from the reference capacitances.  Signals representing the differences between the output signals and the signals coming from the external auxiliary references are formed. Feedback signals controlling the measurement electronics circuit are formed from the signals.  The measurement electronics is con-trolled by the feedback signals in such a direction that the dif-ferential signals approach zero or a preset corresponding value. The output signal corresponding to the capacitance to be measured is determined by the measurement electronics adjusted correctly. The object is to provide a more precise method as well as such a two-reference measurement method and measurement circuit in which complicated computation operations are avoided.  The output vari-ables corresponding to the reference detectors remain unchanged, even if the measurement electronics should creep.  Such a circuit may be used in the telemetry of radiosondes in the measurement of atmospheric pressure, temperature and/or humidity.

Abstract: C-3,614 A REFLECTIVE ACOUSTIC FLUID FLOW METER     Abstract of the Disclosure In one embodiment, a first air flow meter includes a pair of ultrasonic transducers mounted on one wall of a conduit, and an opposite reflective wall is shaped to focus acoustic signals from one transducer to the other.  In a second embodiment, the opposite wall is separated into a stepped series of cylindrical reflective surfaces spaced from the transducers by different distances, each surface being one-half wavelength from its adjoining surfaces so that constructive combination of the acoustic signals occurs.  For noise of the same wavelength emitted at sources axially spaced from the transducers, the reflective surfaces appear to be spaced by approximately 3/4-wavelength steps so that reflected noise signals tend to cancel.

Abstract: ARC FURNACE WITH VARIABLE CAPACITY              ABSTRACT OF THE DISCLOSURE    An arc furnace is provided with a variable-capacity ring which is placed at the top of a furnace body and which is split into a plurality of circumferential sections which in turn define in combination a top furnace wall portion, and a driving mechanism for causing the ring to move horizontally.  As the ring is moved radially outwardly or inwardly of the furnace body, the height of the furnace body is varied and consequently the capacity or the volume of the furnace body can be varied.  As a result, the overcharging of the charge (scrap) is much facilitated; that is, the number of back charges can be reduced.  Furthermore, when the pile of the charge in the furnace body is lowered, the capacity or volume of the arc furnace is decreased so that unwanted thermal losses and oxidation and resulting wear of electrodes can be reduced to a minimum.

Abstract: THERMOSET BONDING AGENT FOR NON-DISORTION JOINING OF SELF-SUPPORTING THERMOSET COMPONENT PARTS          Abstract of the Present Invention A method of bonding areas of two elements of a sheet molded compound to form a bonded product includes intimate mixing of a thermoset epoxy or polyurethane adhesive with submicron particles selected from the group of gamma Fe2O3 and magnetic iron oxide Fe3O4, with the particles typically being 5 to 40% by weight of the final adhesive mixture to form a semi-liquid adhesive mixture.  A bead of the adhesive mixture is located between the elements to be joined, and the elements are forced toward each other to compress and spread the semi-liquid adhesive mixture to form a flattened bonding element in intimate contact with the surfaces to be joined with an accurately controlled typical thickness of the adhesive of 0.005 inches to 0.2 inches.  An induction coil is coupled to the elements and energized with a high frequency current of a frequency of from 1.5 to 8 MHz for a total period of about thirty seconds.  The current level and time is controlled to first rapidly heat the adhesive without significant heating of the elements, and after the cure temperature is reached to reduce the power input and hold an optimum heat level for a sufficient time to create a gel condition.  The bonded product is then transferred for further working.

Abstract: Abstract of the Disclosure:          In a data distributor for distributing an output data signal to an output port in response to an input data signal divisible into a plurality of channel signals arranged in channels, respectively, a position number signal is specific to a position of the data distributor and converted by a converting unit into a specific channel number signal representative of a specific one of the channels.  The specific channel number signal is compared by a comparator with each channel number signal received in synchronism with the channel signals, to detect coincid-ence therebetween.  On detection of coincidence, an AND gate allows a part of the input data signal to pass therethrough as the output data signal.  The specific channel number signal is produced by comparing the position number signal with a sequence of port number signals given from a first signal source and representative of each output port and by loading a memory unit with one of internal channel number signals sent from a second signal source, in response to a result of comparison.     The one of the internal channel number signal is delivered as the specific channel number signal to the comparator.
