Abstract: Abstract of the Invention A power-up and power-down mast and carriage assembly for a lift truck of the type having a stationary mast section fixed to the truck, a movable inner mast section reciprocable within the stationary mast, a fork carriage movably associated with the inner mast section, a double-acting hydraulic ram having an extensible and retractable cylinder and piston rod assembly operatively connected between said mast sections for extending and retracting the inner mast section relative to the stationary mast section.          Lost-motion couplings interconnect both power-up and power-down chains with the stationary mast and carriage in a closed loop chain rigging system.  The lost-motion couplings each have a rod slidably through the inter-connection with the carriage and stationary mast, and spaced stops operable to limit travel of the rod to a predetermined distance.  Coil springs connected to the rod yieldably bias the chains so as to exert tension thereon in a direction opposite to the load forces imposed on the chains by the ram.  The lost-motion predetermined travel distance preferably is equal to the sum of the travel of the lost-motion coupling of the powered chains during initial application of ram-applied forces thereto plus the maximum elongation of the powered chains under maximum rated load so that the non-powered chains are always maintained in taut condition in both power-up and power-down modes of operation of said mast.   23.

Abstract: ABSTRACT OF THE DISCLOSURE     The disclosure is directed to an apparatus and method for encoding and/or decoding video signals for use in a compatible high definition television system or in other applications.  In a form of the disclosure there is provided an encoder which stores an input frame as an array of digi-tal pixel values.  The stored array is interrogated to generate a sum signal and at least one difference signal.          The sum signal is representative of the sum of the pixel values in a group of pixels.  The difference signal is representative of the difference between the total of the pixel values in some of the pixels in the group and the total of the pixel values of other pixels in the group.  The sum signal and the difference signal are generated for a multiplicity of groups which cover the video frame.  The sum signal is generated at a relatively high information rate and the difference signal is generated at a relatively low information rate.  In the decoder the sum and difference signals are combined to obtain an output pixel value for each pixel of an output video frame.

Abstract: A SEISMIC EXPLORATION SYSTEM AND AN ANALOG-TO-DIGITAL CONVERTER FOR USE THEREIN            Abstract An analog-to-digital converter especially suited for seismic data recording applications operates using the differential pulse code modulation method.  A digital linear predictor 40 is used to generate a digital predicted input signal, which is converted in a digital-to-analog converter 44 to an analog signal which is directly compared to the actual input signal 42.  The error signal thus generated is converted to a digital error signal for addition to the predicted signal prior to transmission to means for recording the output signals, and is used for updating of the predicted signal according to the linear predictor 40.  Quantization noise is reduced by highly oversampling the input signal, and a low pass filter 46 smooths the digital output signals.

Abstract: DISPOSABLE ABSORBENT MAT STRUCTURE FOR REMOVAL AND RETENTION OF WET AND DRY SOIL AND METHOD OF MANUFACTURE                         ABSTRACT A disposable absorbent structure for the removal and retention of moisture and/or particulate from a soiled object coming in contact therewith. The structure preferably comprises a macroscopically patterned, three-dimensionally expanded, shear resistant uppermost layer having an object contacting surface and a non-object contacting surface, said uppermost layer exhibiting a pattern of protuberances extending upwardly from a first plane and terminating in a second plane substantially parallel to and remote from the first plane. The uppermost layer further exhibits a multiplicity of discrete apertures in its second plane and is pervious to moisture in its first plane. A moisture absorbent substrate having its uppermost surface coextensive with the uppermost object contacting layer is secured substantially continuously to substantially all of the non-object contacting surface of the uppermost layer. The discrete apertures located in the second plane of the uppermost layer expose the subjacent portions of the moisture absorbent substrate directly to the soiled object when the disposable absorbent structure contacts the object. Under normal use conditions, the portions of the uppermost layer initially located in the first plane and the portions of the uppermost layer initially located in the second plane undergo resilient deformation to move closer toward one another, but do not become coplanar with one another when subjected to compressive loads. When the compressive loads are removed, they move in the direction of their initial positions. Absorbent structures of the present invention function to transfer moisture and/or particulate from a soiled object into the moisture absorbent substrate via the discrete apertures in and/or the moisture-pervious portions of the uppermost layer of the structure. Once moisture and particulate enter the moisture absorbent substrate, they are effectively isolated from objects coming in contact with the structure by the uppermost object contacting layer.
