Abstract: ABSTRACT OF THE DISCLOSURE          A cooling tower monitor for determining the performance of a cooling tower includes temperature transmitters for determining the input water temperature, the output water temperature and the surrounding temperature of the tower.  A flow transmitter measures the output flow of water and a speed transmitter determines the flow of air through the tower.  A relative humidity transmitter is also utilized to measure the surrounding relative humidity.  The transmitters are connected to function blocks to generate a value corresponding to the performance of the cooling tower as a function of the parameters measured.  A first set of function blocks utilizes the surrounding temperature and relative humidity to calculate the wet bulb temperature of the air outside the tower.  This measurement is utilized in conjunction with the input and output temperatures as well as the air flow value to calculate a nominal or available water flow rate for the tower.  A standard condition tower unit and rating factor for the tower are utilized in this calculation. The available flow is then divided into the actual flow as determined by the water flow transmitter to obtain the performance value.

Abstract: Abstract of the Disclosure A Mounting For A Linkage Arrangement Earthmoving vehicles are often provided with a linkage arrangement on one end that is utilized to manipulate a work implement, such as a loader bucket. The linkage typically includes a tilting arrangement for the bucket that incorporates a tilt lever that is mounted to a lift arm that supports the bucket.  The mounting between the tilt lever and the lift arm is normally of a complex nature requiring multiple bearing surfaces and lubrication means.  Others may have a structure that requires exact positioning between the relative components or a failure will occur due to improper loading.  The linkage arrangement of the present invention provides a mounting member that is attached to only one of the tilt levers.  It also includes an axial motion limiter that is attached to the other tilt lever.  In doing so, a very simple and economical mounting device is provided.  The mounting device also allows the tilt levers to rotate with respect to each other so that each of the levers function to bear a portion of the loading.

Abstract: : The present invention relates to a method of making a VLSI DRAM device in a semiconductive member. The method comprises the steps of forming trenches in a portion of the member that exhibits a specified conductivity type. The trenches each include walls that extend into the member from a main planar surface thereof, whereby edges are defined where the trench walls meet the main planar surface. The method further includes the step of masking the entire main planar surface of the member except for limited surface portions that extend a prescribed distance away from the edges, simultaneously introducing dopants of the opposite conductivity type into shallow regions below the surface portions and below the trench walls to form in and adjacent to each trench in the semiconductor member a continuous conductive layer that comprises a conductive trench layer and a conductive laterally extending surface extension thereof. Finally, the method includes the step of forming an associated MOS transistor, including source and drain regions, in the same semiconductive member adjacent each trench to establish one region of each such adjacent transistor in electrical contact with a portion of the laterally extending extension of the adjacent trench layer.

Abstract: ABSTRACT OF THE DISCLOSURE    A rearview mirror system comprises an electrically controlled optical transmission plate disposed over a reflecting surface.  The optical transmission plate is selectively operable to any of a number of different states of opaqueness between a maximum light transmission and a maximum opaqueness.  The opaqueness of the optical trans-mission plate is controlled by an electronic circuit which includes two sensors, one for sensing the brightness of incident light from the field of view and the other for sensing ambient light.  The control operates to cause the light which is incident on the reflecting surface to be closed loop regulated to a desired degree of brightness which is also correlated with ambient light conditions. A manually operable adjustment is also provided for the observer to set a desired brightness characteristic.

Abstract: WEIGHTED-PIXEL CHARACTERISTIC SENSING SYSTEM                  Abstract of the Disclosure A system for sensing a characteristic of a document, e g. translucency, by using radiation from the document at a specific window area.  The identified window area is illuminated to provide radiation from the area which is sensed by pixel dissection so that pixels of central location in the window area are weighted for greater significance.  The pixel weighting attributes greater significance to the central portion of the defined area thereby increasing the tolerance of the system to misalignment of the window area.  The observed characteristic is reduced to signal represen-tations which are compared with registered values as to authenticate the document.  Pixel-weighting tech-niques include overlapped pixels, filtered pixels and algebraically weighted pixels.
