Abstract: ABSTRACT            A seatback latching mechanism for use in a vehicle seat assembly having a backrest member pivotally tiltable over a seat member. The mechanism has a first latch means fixed relative to the seat member and a second latch means pivotally mounted on the backrest member for pivotal movement thereof between an unlatched and a latched position in which tilting movement of the backrest member over the seat member is restrained.  Pendulum means are pivotally mounted on the backrest member for pivotal movement independently of the pivotal movement of the second latch means between first and second pendulum limit positions at which limit positions the pendulum means impinges upon the second latch means.            In the normal upright position of the backrest member, the pendulum means is gravity biased to the first limit position in which the composite centre of gravity of the pendulum means and the second latch means is positioned eccentrically of the pivot axis thereby urging the second latch means towards the unlatched position.  Upon the occurrence of a first vehicular deceleration force sufficient to overcome the gravity biasing of the pendulum means to the first limit position, the pendulum means pivotally moves to the second pendulum limit position thereby increasing the sensitivity of the mechanism to latching, such that, upon the attainment of a second greater vehicular deceleration force, the second latch means moves rapidly to the latched position thereof.

Abstract: ABSTRACT A three-sided, rectilinear bridge or culvert structure comprises a pair of vertical side walls set in preformed or cast in place footers or existing supports and an integral, planar, horizontal span.  Integrally cast haunches having curved or planar faces are disposed at the inside corners of the side walls and span and extend farther along the span than the side walls.  The footers preferably include a side wall receiving channel on their upper surfaces.  There is no lower or bottom portion of the structure such as is found in conventional box culverts and thus, that region between the footers and side walls is open and readily permits water flow through the structure in its natural watercourse, lessening the likelihood of debris collection within the structure.  The structure is cast concrete reinforced with conventional reinforcing bar or welded wire mesh.  A side range of rise/span (height/width) proportions may be accommodated in structures having spans up to about thirty feet.

Abstract: FUEL TANK VENTILATING SYSTEM        Abstract of the Disclosure An arrangement for limiting the filling of tanks and for aeration and ventilation of tanks in which a portion of the tank volume acts as a pressure-compensation space for temperature changes, has an aeration and ventilation arrangement opening into the aeratable and ventable filler neck, said arrangement having a filling vent which determines the maximum allowable liquid level and an operating vent to take over aeration and ventilation of the pressure-compensation space with a sealing arrangement, such that the operating vent is sealed off by the action of a spring when the tank cap is removed, and when the tank cap is attached, it is thereby opened against the spring pressure.  Operating ventilation is controlled by a valve integrated into the aeration and ventilation line which valve can be actuated against spring resistance by a plunger rod.  The valve is placed in the filler neck in such a way that the plunger rod runs parallel or substantially parallel to the side of the filler neck within the same filler neck, and its free end projects from the filler neck when the tank cap is removed.

Abstract: Abstract An  automatic/remote  instrument monitoring  system and method are disclosed. RF transponder units are operatively connected to and monitor one or more para-meters of a remotely located  instrument.   The trans-ponders  include RF receivers  that sample received RF signals at a low duty cycle and look for a common wake-up signal transmitted from a mobile data collection unit.   All transponders receiving  the common wake-up signal simultaneously energize their respective trans-mitters and transmit their respective messages over a predetermined RF transmission bandwidth to receivers in the mobile unit.   The time and frequency parameters of the transponder  transmissions are varied  in a manner such  that  the  transmission  signals of  simultaneously transmitting transponders differ. A plurality of RF receivers in the mobile unit are respectively tuned to collectively receive the transponder transmissions, across the entire transmission bandwidth.  Decoding and signal processing circuits in the mobile receiver unit identify  transmitting  transponders  and  process  their respective messages.

Abstract: Attorney's Docket No. 7649 CAN      INVENTOR:  PETER BOEGLI            INVENTION: PASSIVE TRACK SYSTEM FOR GUIDING AND CONTROLLING            DRIVERLESS TRANSPORT AND ASSEMBLY OR INSTALLATION DEVICES                 ABSTRACT OF THE DISCLOSURE           The passive track system comprises a passive track formed as a highly reflective strip adhered to the floor and containing a bar code,  vehicle-supported passive track reading devices for forward and reverse travel as well as a bar code reading device.  The passive track system can be operated as a passive track guidance system or as a passive track control system or both.  The vehicle follows the passive track or guide path by continuously monitoring the travel lane on both sides of the central longitudinal axis of the vehicle using track sensors located in reading heads.  In the method,  sets  of actual values thus measured are cross-correlated with a set of reference values corresponding to the track positions and stored in an electronic evaluation device.    The appropriate cross-correlation  function is calculated for each "observation" using a special track guidance algorithm and then a track position of the vehicle as well as a quality or system condition factor for the passive track system are derived.  Control is also effected by the passive track.  The vehicle decodes the bar code using code sensors and processes it as a control signal.  The passive track is useful both as a control line for track guidance and as a signal source  for functional control.          Since the passive track is easily and quickly applicable to and removable from the floor, it renders possible a freely chosen layout of the travel network and thus an optimal utilization of the flexibility of trackless vehicles.

Abstract: ABSTRACT         An electronically scanned radiometer has a dispersive serpentine antenna with one or two ports.          A mixer is connected to each port with each mixer being fed by a variable frequency local oscillator.          Each oscillator provides the mixer to which it is connected with a drive signal that varies in frequency  The antenna most efficiently receives one or more beams through radiators at an angle that varies with the frequency of the drive signal at the mixer.  An output is received at each port and is appropriately displayed.  When the serpentine has two ports the radiometer can be operated at two orthogonal polarizations.  The frequency being fed to each mixer can be varied in various pre-determined patterns.          Scanning of the beam can be effected by changing the frequency of observation without physically rotating the antenna.  Also two simultaneous beams rotating in opposite directions with independent motions can be achieved.
