Title: Air conditioner unit for mounting on or in the roof of a vehicle
Inventor: KING DONALD D
IPC: F25D19/00
Filed: 1991-04-08
Abstract: 55,911 ABSTRACT OF THE DISCLOSURE         An air conditioner unit mounted on or within the roof of a vehicle.  The frame of  the unit  functions as a substantially  flat  support  pan for the air conditioning components, while  having  a  lower  portion  which accom-modates a generic curved contour of most vehicles the unit will be associated with, such  as  buses.    The  frame is devoid of  upstanding wall  portions on the sides adjacent to the sides of the vehicle, and on the ends  of the frame which approach  the sides.  This frame structure facilita-tes  the  manufacture  of  the  frame,   the  assembly  of components on the frame, and servicing of the unit, and it enables the  manufacturer  of  the  vehicle  to  provide a bubble  or   skin  for  the  air  conditioner  unit  which accommodates the design and aesthetics of the vehicle.

Title: Pipe-laying apparatus
Inventor: WISE EUGENE E
IPC: F16L1/06
Filed: 1991-05-29
Abstract: ABSTRACT OF THE DISCLOSURE      Apparatus for laying pipe in a trench includes a housing with a bottom, side walls, a leading end wall and a trailing end wall, with a tapered nose at the leading end, the nose being designed to be pulled along a trench by a backhoe.  The nose is hinged to the leading end wall and can be pivoted up and down when the housing is moved along the trench.  The housing includes a trough which receives and orients a pipe and a pusher which moves the pipe along the trough and into assembled relationship with an end of a previously-laid pipe. A hopper near the trailing end of the housing has a chute which deposits fill material around the pipe.  The trailing end wall has an opening with a slidable door to strike off the top of the fill material.  Mechanism is connected to the trough and door to simultaneously move them up and down to maintain the pipe on grade and to maintain the depth of fill material constant relative to the pipe.  The pusher includes a cart with gears which engage tracks on sides of the trough, the gears being driven by a fluid-operated motor which receives high fluid pressure when the pipe engages a previously-laid pipe, in order to assemble them.  A sensor system sends signals through the pipe to receivers in the housing and in the nose to indicate the grade and alignment of the pipe.

Title: Adaptive sparse echo canceller using a sub-rate filter for active tap selection
Inventor: YATROU PAUL M
IPC: H04B3/23
Filed: 1992-02-05
Abstract: With the presently described echo canceller, a sparse adaptive transversal filter is used to model and cancel only the active regions of the echo impulse response.  Since the tap coefficients, in the dormant regions, are set to zero and have no random fluctuation this approach reduces computation time and excess mean-square error in the tap coefficients.  Also, the present design provides for increased speed of convergence of the sparse canceller as compared to the full-tap canceller, since convergence is proportional to the number of active taps in the LMS algorithm.

Patent CA-2066529-A1 (CA)
Inventor: KOJIMA SUSUMU
IPC: H04L5/22
Filed: 1992-04-21
Abstract: In a cellular communications system, the quality of a signal over a first two-way connection from a destination to a mobile terminal is compared with a threshold. When the signal quality becomes lower than the threshold, a second two-way connection is established and a switching request signal and an information-bearing signal are sent from the mobile terminal through both connections to a switching exchange. In response to the request signal, one directional path of the first connection is cleared by the exchange to prevent a version of the signal passing through the first connection from reaching the destination and a first switching complete signal is sent through the other path of the first connection to the mobile terminal to allow it to clear the first connection and return a second switching complete signal. The other path of the first connection is then cleared by the exchange in response to the second switching complete signal.

Title: Automated tool measurement
Inventor: HEILIG GUENTER
IPC: G05B19/18
Filed: 1992-06-22
Abstract: ABSTRACT        In an apparatus for the automated measurement of a tool on a grinding machine or other machine tool having a coordinate carriage enabling the tool to be adjusted in two dimensions in a common plane, the carriage bears an imaging camera  connected  to  an  image  processing  computer  and directed at the tool cutting-edge.  The camera has a planar array with computed crosshairs stored as an associated reference system in the image processing computer, and the carriage is equipped with motors controlled by the image processing  computer  to  adjust  the  carriage  in  both coordinate directions.    The  image  processing  computer operates  under  control  of  a  program  which  constantly ascertains  the distances  of  the  cutting-edge  from the coordinate axes of the crosshairs and outputs pulses to the motors to move the carriage until, in a new tool position, the deviations in the X and Z directions are nulled and hence the tool has been accurately measured.   The image processing computer is connected through an interface to a digital  counter  displaying  the  toll  cutting-edge's coordinate values X, Z in relation to the tool holder.

Title: Mobile vehicle on-board weighting system
Inventor: KARPA MICHAEL J
IPC: G01G19/08
Filed: 1992-07-30
Abstract: ABSTRACT:             This invention relates to the design and construction of a weighing device to mount on mobile vehicles which have lifting means, like fork lift trucks equipped with front forks. In ess-ence we provide a new fork or lifting lug assembly incorporating commercial load cells. The cantilevered fork loading moment is accommodated by upper and lower shear plateswhich are anchored to preloaded spring package supports. An overload will allow the springs to deflect and the excess load to be shunted to stops.      The load cell also incorporates a preloaded spring mount and also shunts excess loading to a stop. The use of preloaded spring mounts allows a relatively large movement (about 1/8 in.) before the stops are engaged this results in stops being insensitive to slight deformation and corrosion, debris, etc. accumulation. A single fork is ideal for dosing (adding or subtracting liquids by weight) operations with the 2 normal forks at each side as safety aids. The system can built into virtually any specialty veh-icle handling containers as the weighing assembly can be simply shaft mounted.
