Abstract: Abstract:            Method for the transmission of information, in which the signals are coded by way of the magnitude of the ampli-tudes of the half-waves or periods of a sinus-wave alter-nating current Due to pulse amplitude modulation (PAM) there is an un-wanted signal being undesirably strong and a broadening of the frequency band as a result of the pulses. In the case of digital binary-coding of signals with half-waves or periods of an alternating current and the code elements having small and large amplitude values, high frequencies are required. In the present invention, the samples of the pulse amplitude modulation of signals ranging from single polar/binary to continuous are being coded by half-waves or periods of an alternating current, also providing alternating currents of a lower frequency with predeter-mined mutual phase shifting for the samples. Due to these measures the aforementioned shortcomings are avioded.

Abstract: ABSTRACT OF THE DISCLOSURE      A continuous flow well bore perforation washing tool is  shown  of  the  type  having  a  tubular  mandrel  with sidewalls  defining  a  flow passage,  an  upper  end  for connection in a pipe string and a lower end with means for blocking  the  flow of  fluid  from the pipe  string through the mandrel.  Upper and lower pressure responsive packer assemblies are carried on opposite ends of the mandrel.  An outer setting sleeve surrounds the mandrel between  the  packer  assemblies  to  define  an  annular chamber  between  the  mandrel  and  setting  sleeve.   A continuous   flow   passage   communicates   the   mandrel interior,  the  annular  chamber,  and  the  well  bore.          Selectively sized orifices in the setting sleeve form a restriction in a portion of the continuous flow passage.          By  selectively  sizing  the  orifices,  a  back  pressure buildup can be created in the annular chamber which is used  to  set  the  packer  assemblies  as  fluid  is continuously flowed through the continuous flow passage.

Abstract: ABSTRACT        The invention is a rotary transfer apparatus for transferring poultry carcasses from the shackles on one conveyor line to the shackles on another conveyor line.  In particular, the apparatus of the invention can be used for transferring carcasses between a kill line and an evisceration line, a rotary member of the apparatus being positioned between those lines.  The transfer apparatus may include a knife mechanism for removing the lower part of the legs of each carcass.  The knife mechanism is fixed to the frame of the apparatus at one position on the periphery of the rotary member and acts on the carcasses as they pass that position.  The apparatus of the invention is intended in part to replace what is at present in many poultry plants a manual operation.

Abstract: TITLE               Use of Anti-Idiotype Antibodies in Immunoassays ABSTRACT OF THE DISCLOSURE The invention relates to a homogeneous immunoassay for the determination of an unknown concentration of an analyte in a liquid sample.  The assay includes the step of incubating an idiotypic, anti-analyte antibody, an antigen or a hapten, and an unknown amount of analyte.  At least one member of the group consisting of idiotypic, anti-analyte antibody, antigen and hapten is labelled with reagent means for determining the extent to which the antigen or hapten is bound to the idiotypic, anti-analyte antibody.  The assay uses an anti-idiotype antibody as the antigen or hapten.

Abstract: IMPROVEMENTS IN THE ENCAPSULATION OF ELECTRONIC COMPONENTS         Abstract of the Disclosure An improved thermoplastic molding composition is provided which is particularly suited for use in the impervious void-free encapsulation on a relatively expeditious basis of an electronic component wherein the preformed electronic component is positioned in a mold cavity prior to the introduction of the molding composition via injection molding.  The molding compo-sition comprises a melt processable thermotropic liquid crys-talline polymer which is of a relatively low weight average molecular weight of approximately 4,000 to 25,000 (e.g. approx-imately 4,000 to 10,000) and which is substantially incapable of further chain growth upon heating.  Uniformly dispersed within the liquid cystalline polymer is approximately 40 to 80 percent by weight (e.g. approximately 50 to 75 percent by weight) of a particulate inorganic material (preferably of silicon dioxide) which serves to advantageously decrease its volumetric coefficient of thermal expansion and to advanta-geously increase its thermal conductivity.  In a preferred embodiment the electronic component which is encapsulated is a semiconductor device, such as a relatively delicate quad or dual-in-line integrated circuit device which is assembled onto a flat prestamped lead frame or other conductive device having a plurality of leads which extend outside the area which is en-capsulated.  The resulting encapsulated electronic component is well protected in spite of the relatively low molecular weight of the liquid crystalline polymer and is capable of satis-factory service for an extended period of time even if adverse environmental conditions are encountered.  A rugged commonly non-burning and relatively inexpensive package is provided.

Abstract: ABSTRACT    IMPROVEMENTS IN OR RELATING TO MOULDING.     In the continuous vacuum forming of articles from a fibrous slurry, e.g. from paper pulp, a plurality of two-piece hinged moulds are mounted on a transport apparatus 1 which transports the moulds stepwise in a loop.  The internal surfaces of the moulds are defined by wire gauze or mesh 107,109 and the moulds are connected to a source of suction.    The moulds, with the suction applied, are moved through the fibrous slurry contained in a tank 43, whereupon fibres are deposited on the mesh 107,109, much of the water being drawn off by the suction.  The mould passes through a drying station, where warm air is sucked through the mould, further drying the article.    The transport apparatus 1 is movable pivotably about an axis 6 by means of a fluid-operated ram 25. At the top of the path, the mould and the article therein are lowered onto a pin 61, a plurality of which are situated on an endless conveyor 59.  By means of rods 81,81, and springs 83 attached to the mould pieces, the mould is opened, and the transport apparatus is lifted, leaving the article on the pin 61.  After cleaning with a spray 65, the mould is then ready to undergo another cycle.

Abstract: ABSTRACT OF THE DISCLOSURE     A press-out piston is movably displaceable through an axially extending container holding a flow-able plastic substance for dispensing the substance as the piston is forced through the container.  The radially outer circumference of the piston has an annular groove in which an elastically deformable seal-ing ring is positioned. The base of the groove is conically shaped about the axis of the container and diverges outwardly toward the rear end of the container. when the piston is pressed toward the front end of the container for dispensing the substance, the sealing ring is moved axially relative to the piston and is pressed radially outwardly against the inside surface of the container.  As a result, the seal for the piston is dependent on the pressure directed against the sub-stance for dispensing it out of the container.

The uniformi-ty of the magnetic flux within the first set of coils is not adversely affected by the magnetic flux produced by the second set of coils.  In a preferred embodiment the coils of the first set are independently energized to establish  a  uniform  field  within  the  coils  having suppressed lower order derivatives of flux with respect to position within the uniform field.   The  external field of the first set of coils comprises a dipole which is offset by the field of the second set of coils. Higher  order  multipoles  beyond  the  dipole  are  also suppressed by the geometries of the two sets of coils.
