Abstract: INVENTORS:  ALFRED WUTHRICH, ANDREAS SCHEIDWEILER and JURG MUGGLI INVENTION:  METHOD OF AND APPARATUS FOR SIGNALLING AN ALARM           ABSTRACT OF THE DISCLOSURE           In the apparatus for signalling an alarm,  for example, in a gas or fire detecting installation, a detector is reset after a first response and the time duration until the next-following detector response  is determined and classified with respect to three classes of time periods.          When the time duration until the further detector response is beyond a predetermined upper or outer time limit, no alarm signal is released and the apparatus returns into its original state.  When the further detector response occurs between two time limits, the alarm is immediately signalled.          When the further detector response occurs prior to a lower one of the two time limits, there is carried out still one further test during which the detector is once again reset.          The alarm signal will only be released if an additional further detector response is still observed prior to the upper time limit.  In this manner the reliability of alarm signalling can be enhanced and the  frequency of the occurrence  of  false  alarms,  particularly  due  to  the occurrence of short-time or brief spurious conditions, can be significantly reduced.

Abstract: SYSTEM FOR IMPROVING SIGNAL-TO-NOISE RATIO IN A DIRECT SEQUENCE SPREAD SPECTRUM SIGNAL RECEIVER                            Abstract A plurality of transmitters synchronized to a common clock each  transmit  a  data  signal spread  by  a  common  bipolar pseudo-random  code  having  a  different  assigned  code  sequence shift.  A receiver, synchronized to the clock, discriminates the signal  transmitted by a predetermined  transmitter  from signals transmitted by the others by generating a first pseudo-random code that is a replica of the common bipolar pseudo-random code and has a code sequence shift corresponding to that of the predetermined transmitter,  and a second bipolar pseudo-random code that is a replica of  the  common  bipolar  pseudo-random  code  and  has  an unassigned code sequence shift.  The difference between the first and  second bipolar  pseudo-random  code  sequences,  which  is  a trinary  code  sequence,  is  cross-correlated  with  the  incoming signal.  The cross-correlation despreads only the signal having the predetermined code sequence shift.  Each receiver includes a number  of  correlation  detectors  offset  from  each  other  by  a fraction  of a  code  chip,  together  with decision circuitry to identify cross-correlation peaks for optimum synchronization.  The output of each sub-receiver  is processed to extract data using weighting factors selected according to the particular distortion present, to improve signal-to-noise ratio.

Abstract: EROSION RESISTANT SOFT SEATED VALVE TRIM     Abstract of the Disclosure The disclosure is related to a high pressure fluid control valve including valve seat made from a resilient, deformable material and a main valve plug which is matable with the resilient, deformable valve seat. A selectively, axially displacable valve stem is associated with the valve plug whereby a contact load placed upon the valve plug by the valve stem will cause the valve plug to be become imbedded within the deformable material comprising the valve seat when the valve is closed and thereby conform the deformable seat precisely to the contour and configuration of those portions of the valve plug which mate with the valve seat. In this manner, a precise zero-leakage mating is obtained each and every time the plug is mated with the seat. In accordance with the invention, an auxiliary throttle plug is associated with the main valve plug and is arranged to mate with a second, metal valve seat which is arranged in an area removed from the resilient, deformable valve seat. The axial movements of each of the valve plug and the throttle plug are coordinated in a manner whereby the primary throttling areas for the fluid flow, particularly during valve opening and valve closing operations are displaced to portions of the valve structure which are remote from the resilient, deformable valve seat.

Abstract: ABSTRACT         A continuous tone image recording system includes a solid state laser diode for generating an analog signal-controlled, intensity-modulated beam of light.  Also included is a feedback circuit responsive to the instantaneous intensity of the light beam for continuously providing a feedback control signal coupled to the laser diode for adjusting the laser diode to stabilize its light output.  This allows virtually instantaneous changes in output intensity in response to an input signal while maintaining the output constant regardless of changes in the characteristics of the laser diode.  The system also includes a lens, mirror, or prism for collimating, focusing, and controlling the path of the beam of light.  Also included in the system is a mirror, galvano-meter or deflector for scanning the light beam across the width of an image plane at which a photosensitive recording medium having a sensitivity and exposure range matched to the intensity-modula-ted light beam may be positioned to provide scan lines on the recording medium.  The scanned lines are positioned consecutively and accurately along the length of the image plane.  The combina-tion of the recited elements enables the formation at the image plane of a continuous tone image, the elements being capable of creating at least 64 gray levels when imaged onto a transparent medium or at least 32 gray levels when imaged onto an opaque medium.
