Abstract: ABSTRACT OF THE DISCLOSURE   Apparatus and method for providing an automatic frequency tuning system capable of supplying a local oscillator signal with a preselected frequency.  The frequency of an output signal of the local oscillator is electronically varied across a frequency region which includes the pre-selected frequency.  The output signal of the local oscillator is combined with the output signal of a reference signal generator.  After the combin-ation of the local oscillator signal with the reference oscillator signal produces a preestablished condition which is the result of the local oscil-lator signal attaining the preselected frequency the frequency of the local oscillator signal is held constant.  The local oscillator signal is there-after compared to the reference oscillation signal and a change in the local oscillator signal frequency is corrected by means of an automatic frequency control feedback loop containing a discriminator circuit.

Abstract: ABSTRACT OF THE DISCLOSURE           Resin tubes having thick walled portions and thin walled portions are formed by providing a specially configured orifice on an extruder and varying the rate at which the extruded resin tube is pulled from the extruder.  The orifice is shaped to form a thin tubular opening and a thick tubular opening communicating with one another, the thick tubular opening being adjacent and down-stream of the thin opening.  When the extruded resin tube is pulled at a high speed the thin tubular opening is filled with resin that passes through but does not fill the thick tubular opening.  At the slow pulling speed the resin fills at least open end portion of the thick tubular opening thereby forming a thick walled portion of the resin tube.

Abstract: METHOD OF MAKING A DUO-DENSITY SILICON NITRIDE ARTICLE      Abstract of the Disclosure A method of making a duo-density article of silicon nitride is disclosed.  A first element is made of silicon metal particles.  The first element is nitrided so that the silicon particles are transformed into sub-stantially pure silicon nitride.  All but a bonding surface of the first element is encapsulated to form a die member.  The die member is placed in a pressing die structure so that its bonding surface forms a portion of the internal surface of the die volume.  The die volume of the die structure is filled with a mixture consisting of silicon nitride particles and a densification aid.          The mixture is compacted in the die volume to at least 98% of theoretical density thereby forming a second element of the duo-density article while simultaneously bonding the second element to the first element along the first element's bonding surface.  The encapsulant is removed from the first element to produce the final article of silicon nitride having two zones of different density.

Abstract: ABSTRACT OF THE DISCLOSURE This invention relates to an improved digital weight measuring and computing apparatus with automatic zero correction which automatically corrects the zero indication of the apparatus.    The weight measuring apparatus comprises a scale which employs a load cell and strain gauge to develop an analog voltage representing the weight on the scale.  An analog-to-digital con-verter is then employed to change the analog voltage into a digital representation of the load on the scale.  The digital converter provides a digital indication in addition to the digital indications employed to indicate the weight on the scale. The additional digital indication represents fractions of the least weight increment indicated of the weight on the scale. The additional digital indication is then employed to control the generation of a zero correction factor and this factor is then combined with the weight indications from the scale to indicate the correct weight of articles placed on the scale. The corrected weight in combination with the unit price of the article placed on the scale is then employed to compute the value of the article on the scale.

Abstract: ABSTRACT OF THE DISCLOSURE         In a straddling dowel or expansion anchor assembly a spreader is threaded on one end of a bolt so that by turning the bolt the spreader is pulled into an expansion sleeve for spreading it into anchoring contact with the surface of a borehole.  The opposite end of the bolt has a shoulder provided by a head or nut. Between the expansion sleeve and the shoulder, a yielding member laterally encloses the bolt and yields at least when a minimum anchoring value of the expansion sleeve has been reached.  The yielding member affords a visible indication that the minimum anchoring value has been achieved.  A washer is positioned adjacent the shoulder on one end of the bolt.          Before the expanding action, the washer is spaced from the shoulder on the bolt by the yielding member or by a separate member, however, as the minimum anchoring value is achieved the washer is displaced relative to the member which spaces it from the shoulder, into contact with the shoulder.

Abstract: Abstract of the Disclosure A six cylinder internal combustion engine having first and second groups of three adjacent combustion chambers and an exhaust valve port connected to each of the six combustion chambers.  In each group of three adjacent combustion chambers the exhaust valve ports of the side combustion chambers are positioned on the side of the middle combustion chamber there-by reducing the length and surface area of the exhaust passages and main-taining a high exhaust temperature.  First and second confluence members join the exhaust valve ports of the first and second groups of three ad-jacent combustion chambers respectively to an exhaust reaction chamber. The ignition timing of the combustion chambers is controlled in order that the periods of successive exhaust valve port openings partially overlap. This allows the cooler gases at the end of the exhaust stroke to be heated by the hot gases produced at the ignition of the next successive combustion chamber exhaust stroke which further maintains a high exhaust temperature in the exhaust reaction chamber.

A transversal filter arrangement digitally synthesizes a cancellation signal for unwanted leakage, i.e., echoes, through hybrid junctions directly from the digital data input symbols, rather than from the analog transmitter output.  An error control signal for correlation with tap signals on the transversal filter is derived from the output of the receiver, instead of its input.

Abstract: ABSTRACT OF THE DISCLOSURE           A centrifugal magnetic stratification and elutriation type separator is intended for wet and dry concentration of strongly and weakly magnetic ores by separating the material to be concentrated into several streams and controlling the pro-portion of the magnetic fraction in these streams by adjusting the speed of flow of the separated streams, adjusting the move-ment of magnetic flux interrupters and controlling magnetic flux intensity.  The flow speeds of the separated streams are controlled automatically with the help of closing devices of a simple design, the other kind of control being also automatic. The concentrated product, therefore is separated and has a given proportion of the magnetic fraction, in addition to tailings which have a minimum proportion of this fraction, while the separated intermediate product is recirculated to be crushed additionally.  Since the method and separator operation are based only on the magnetic properties of a flowing stream, there is no need to blend the ore prior to crushing, as well as to blend the concentrate following the concentration process.

The hard wear resistant end cap on the tip of the steel body is joined so that it may easily and quickly be replaced when the punch is in position on the machine thereby providing less down time for maintenance on the extrusion press. The method of joining the hard wear resistant end cap to the steel body minimizes the conditions which tend to fracture hard wear resistant material.
