Abstract: ABSTRACT      "A DISTRIBUTED CONTROL COMMUNICATIONS SYSTEM"       A local area network communications system for a plurality of subscribers has distributed network control and provides random access capability.  Each subscriber (130, 230, 330, 430) is connected to a transmission medium (100) via a respective access unit (120, 220, 320, 420).   Each access unit contains a control unit (121), and network control is progressively transferred from one control unit to the next in a cyclical manner without the need for centralized control.  When a particular control unit has network control, it provides the logical connection between its subscriber and the transmission medium if communication with another subscriber is requested.

Title: Regulator for mounting on the outlet connection of a  gas cylinder or like container
Inventor: HANSEN FRITS U
IPC: G05D16/06
Filed: 1984-08-03
Granted: 1987-04-21
Abstract: ABSTRACT        The housing (5, 6) of the regulator contains a medium-pressure chamber (lO) to which gas is supplied from the cylinder when a self-closing cylinder valve (2) is open and which communicates with the regulator outlet (14) through a further valve (13), and a low-pressure chamber (23) in open communication with the outlet.  The  medium-pressure  chamber  (lO)  has  a diaphragm  wall  (15)  with  a  spindle  (16)  for controlling the cylinder valve (2). The low-pressure chamber   (23)  has  a  diaphraym  wall   (22)   for controlling the further valve  (13)  through a con-necting rod (20) carried by the diaphragm wall and coacting at its upper end with a manual selector (21) and at its lower end with the valve opener spindle (16). By means of the selector the connecting rod may be locked in a raised position in which the cylinder valve (2) is closed.       The connecting rod (20) is associated with a lockable spring mechanism (27) which is unlocked in reponse to a predetermined overpressure in the low-pressure chamber and which then moves the connecting rod to its raised position. This prevents a leakage of gas in case of a ruptured diaphragm or flexible tube if the urther valve (13) does not close tightly when the gas consumption has been discontinued.            (Fig. 1)

Abstract: ABSTRACT:            A flat cathode ray tube having a micro-channel plate electron multiplier spaced a short distance from a fluorescent screen applied to a substantially flat face-plate.  A deflection electrode array is disposed behind and spaced from the electron multiplier so as to he parallel therewith.  An electron gun is disposed laterally of the space between the electron multiplier and the deflection electrode array so that in operation an electron beam produced by the electron gun enters the space along a path of movement substantially parallel to the deflection elec-trode array.  Magnetic scanning means are provided to deflect the electron beam in a plane parallel to the deflec-tion electrode array.  The magnetic scanning means enables a range of different screen shapes and sizes to be made without the risk of deflection defocusing at the edges of the screen and the deflection electrode array enables the depth of the tube envelope to be substantially independent of the screen size.

Title: Piecewise linear digital video signal processing apparatus
Inventor: FLING RUSSELL T
IPC: H04N5/208
Filed: 1985-04-02
Granted: 1987-08-04
Abstract: Abstract Apparatus is provided for processing a digital video signal capable of exhibiting positive and negative values from a source.  A means is provided for producing the absolute value of the digital signal.  A further means produces a signal corresponding to the difference between the absolute values and a reference value supplied from a source.  A polarity discriminator passes differences of one polarity only.  A polarity inverting circuit inverts the polarity of samples applied to its input in response to the polarity of the signal samples occurring at the source of digital video signals.  Means are provided for coupling the polarity discriminator to the input of the polarity inverting circuit.  In this way the output of the polarity inverting circuit is a symmetrically processed signal fictionally dependent upon the reference value.           Alternatively, first and second threshold/polarity discriminators receive respective first and second reference values, supplied from a source at respective reference signal input ports.  Means couple the signal input port of the first threshold/polarity discriminator to the absolute value means and the input port of the second threshold/polarity discriminator to the output port of the first threshold/polarity discriminator.  The threshold/polarity discriminators provide output signals of one polarity only for applied input signals that would exceed the reference value.  A signal scaling means has its input coupled to the output of the second threshold/polarity discriminator.  A signal combiner has one input coupled to the output of the signal scaler and another output coupled to the output of the first threshold/polarity discriminator. A processed digital signal is available at the output of the signal combiner.

Abstract: PRODUCTION OF IMPROVED PELLETS             FROM MELT-PROCESSABLE POLYMER WHICH          IS CAPABLE OF FORMING AN ANISOTROPIC MELT                 Abstract of the Disclosure Improved pellets comprising a melt-processable thermo-tropic liquid crystalline polymer (e.g., a wholly aromatic polyester) are provided.  The molten anisotropic melt-forming polymer, while present as a thin film of the specified thickness at an appropriate temperature, is subjected to reduced pressure conditions whereby residual volatiles are evolved and removed, and the polymer thereby is desified to the specified degree prior to pellet formation.  The resulting densified polymer next is melt-extruded and is cut to form pellets while at an appro-priate temperature.  It surprisingly has been found to be of prime importance that the resulting pellets possess a density of at least 95 percent of the theoretical maximum (e.g., a polymer density of approximately 1.35 to 1.4 gram/cc.) if the advantages of the present invention are to be fully realized.  These pellets have been found to be capable of undergoing melt processing to form shaped articles having improved physical properties.  For instance, such shaped articles exhibit markedly smoother surface characteristics and can be used at elevated temperatures for extended periods of time while better retaining the desired surface characteristics.
