Abstract: Abstract of the Disclosure Apparatus for combining video signals from a video source, such as a video disc player (20), with computer-generated graphics/text output on a single display, for overlaying the two.  The computer-generated video is provided in RGB format (52); the other video is converted (80) to RGB format if not already in that form and the two sets of RGB signals are provided to a switch (90). The switch (90) (i.e., multiplexer3 selects which one of the two RGB signal sets to display; this selection is made separately for each pixel.  In one embodiment, the color of the computer-generated signals (52) controls the switch's selection of source.  A master-slave synchronization system (100) maintains registration between the two sets of RGB signals.  When the video source is unstable (as, for example, with a video disc player), a master sync generator (130-138) provides a house (coarse) synchronization signal (144) to the video disc player.  (For stable sources, this is unnecessary.) The slave synchronization generator (160-270) locks the video switch (30), display (40) and computer video generator (50) to the timing of the video image source (such as video disc player).  Thus, the rest of the system tracks the jitter of the video source (20).  When i  the video disc player (20) is scanning or is being spun up or down, the slave sync generator (160-270) locks onto the house sync signal (148) of the master sync generator, instead of the video disk player's output, to avoid rolling and tearing of the display.

Abstract: DISCRETE RANDOM VARIATES GENERATOR            Abstract Method and apparatus for the rapid generation of discrete random variates, of a general probability distribution, from random variates of a uniform distribution uses simple logic and moderate storage requirements.  Access to a first table at an address which is a function of a uniform variate gives the desired variate value directly for a large percentage of cases and in the remaining cases the desired variate value is obtained by an indexed search of a second table of cumulative distribution function values.  Results of greater precision are realized in faster execution times with less logic complexity and reduced storage bulk as compared with prior methods and apparatus.

Abstract: ABSTRACT OF THE DISCLOSURE             Method and apparatus for welding studs to a work-piece are provided. When studs are welded to workpieces using a drawn-arc, stud-welding technique, a coating of smut is sometimes deposited on the workpiece around the weled end of the stud. This coating detracts from the appearance and if the workpiece is covered with coating material, such as paint, the smut must first be removed, requiring an extra operation.         It has been found that the coating of smut will not be depos-ited,if, during the welding cycle, fluid is carefully deposited on the weld area around the end of the stud where the weld occurs.          This fluild consists of a small volume of low pressure air and an anti-smut liquid.

Abstract: ABSTRACT      Purified antigenically selective vaccines for domestic animals are prepared from microorganism cultures containing the immunizing agent by first complexing the immunizing agent with micro-particles having bound IgG antibodies specific for the immunizing agent, separating the resulting complex, and preparing a vaccine directly therefrom containing the antigen-antibody complex.  The micro-particles preferably have Protein A in their outer surfaces for binding to the specific antibodies.  The complex-containing vaccines provide effective immunization.  The method and the resulting vaccines are particularly useful in preparing viral and bacterial subunit vaccines.

Abstract: ABSTRACT OF THE INVENTION     A video and audio signal recording apparatus includes a first frequency modulator in which a first audio signal to be recorded that may represent a stereophonic left channel modulates a first carrier to produce a first FM audio signal, and a first frequency convertor converts the carrier frequency of the first FM audio signal to a differ-ent carrier frequency higher than the first carrier frequency to form a second FM audio signal.  A second frequency modulator modulates a second audio signal to be recorded that may represent a stereophonic right channel to produce a third FM audio signal, and a second frequency converter converts the third FM audio signal into a fourth FM audio signal having a carrier frequency that is higher than any of the other FM audio signals so modulated.  The first and third FM audio signals are mixed to form a first mixed audio signal and the second and fourth FM audio signals are mixed to form a second mixed audio signal, which are both combined in a mixing circuit with a composite color video signal to form first and second mixed audio and video signals which are fed to first and second magnetic recording heads, respectively.  Reproducing apparatus reproduces-the recorded signal.

Abstract: APPARATUS FOR MAKING STRIPS OF COHERENT PACKETS       CONTAINING GROUND COFFEE OR THE LIKE              ABSTRACT OF THE DISCLOSURE           A strip of coherent packets of compacted batches of ground coffee between two overlapping webs of water-permeable material is formed along the upper reach of an endless conveyor with plates having supporting surfaces facing upwardly during travel along the upper reach and provided with recesses which communicate with a suction generating device.  The first web is deposited onto the supporting surfaces of successive plates at a first station, followed by deformation of the web at a second station to form therein pockets which extend into the respective recesses and receive batches containing metered quantities of ground coffee at a third station. The batches are compacted in two stages to form cakes from which loose particles are sucked up by a nozzle before the second web is placed over the first web and the cakes.  The two webs are then bonded to each other around the respective cakes, and the resulting packets are subjected to a quality control before the continuous strip of coherent packets is subdivided into lengths each of which contains a selected number of packets. The second compacting stage involves rotation of a tool relative to the batch therebelow so that the underside of the tool is free of particles of ground coffee when it is lifted above and away from the thus obtained cake.

Abstract: ABSTRACT     A dispenser for a product is described which incorporates a follower piston slidably mounted therewithin. The dispenser includes an axially extending bore of a tubular container body for housing a product to be dispensed and having an upper end from which the product is dispensed and an open lower end. The follower piston is slidably mounted within the lower end of the-bore of the container body to support the product thereabove.          The piston is constructed of resilient material and comprises a face portion adapted to contact the product and a peripherally attached sidewall. The sidewall further comprises at least one integral peripheral contact band conforming to the shape of the cross section of the bore, and is adapted to virtually resiliently extend or contract in response to axial forces exerted on the face portion with such change in length resulting in an inversely proportional virtual change in lateral dimension of the peripheral contact band. The peripheral contact band is dimensioned to provide an interference fit within the bore which exerts a pre-determined normal force against the inner surfaces of the bore in static condition.

Abstract: PHASE ANALOG ENCODING                 SYSTEM WITH COMPENSATION                           ABSTRACT           A phase analog encoding system with compensation for the phase shift error inherent in a resolver position transducer.  The inherent phase shift error in a resolver position transducer is compensated in a time multiplexed fashion by periodically applying a known reference signal to the resolver and measuring the electrical phase shift across only the resolver.  The newly measured value of the inherent electrical phase shift is compared with the last measured value of the inherent electrical phase shift and any deviation is calculated.  This deviation is used to determine the appropriate compensation value for the inherent electrical phase shift   The compensation value is subtracted from the resolver phase shift during normal operation resulting in an output signal which is independent of the inherent electrical phase shift error in the resolver position transducer.
