Abstract: ABSTRACT            The invention addresses problems with liquid absorbent pads having at least about 50% of their absorption capacity represented by water absorbent (including water-soluble or -swellable) material capable of absorbing at least about 5 times its own dry weight of aqueous liquid.  By openings of specified area, present in undulating layer(s) of such absorbent material in specified numbers and total area per unit area of said layer(s), and/or through forming such openings as hinges and displaced flap members for locking the layers of a moving composite together for bending into said undulating configuration, and/or through use of sheath members of material which substantially retain their structural integrity in contact with aqueous liquids, and have open or openable portion(s), pads are formed with both high absorption rate and capacity and/or ready disposability and/or rapid production characteristics, ideally suited for urinary incontinence care and other uses.

Abstract: ABSTRACT     Method of Cancelling Echoes in Full-Duplex Data Transmission System A first difference signal is obtained by subtracting an echo replica from a mixed signal which consists of a received signal and an echo.  The echo replica is produced in an adaptive digital filter using an error signal.  The first difference signal includes the received signal and a residual echo, and is delayed in a manner to produce a delayed first difference signal.          The delayed first difference signal is subtracted from the first difference signal to obtain a second difference signal.  Thereafter, a polarity of the residual echo included in said second difference signal is detected.          The error signal is obtained based on the detected polarity, and then is applied to the adaptive digital filter.

Abstract: CANADA              INVENTION: HYDRAULIC PRESS INVENTOR:  LEON MALASHENKO AND            JAMES HEPBURN                    ABSTRACT OF THE DISCLOSURE A 2000 ton hydraulic press is described. The press design eliminates the side slabs and substantial cross-head associated with conventional presses. The press simply has a base that includes a lower platen and bolster plate. Four vertical posts extend upwardly through the lower platen bolster plate, and guide structure beneath the lower platen bolster plate constrains the posts to move vertically while bearing horizontal forces and bending moments which may be applied to posts for example during compression of a mold containing a molding charge. Four large-bore, short-stroke hydraulic cylinders are attached to the base below the lower platen bolster plate, and serve to raise and lower the posts during compression phases of operation. An upper platen is interfitted with and guided exclusively by the posts for vertical movement, and a pair of small bore, long stroke cylinders operating between the lower and upper platens serve to raise and lower the platen in a rapid manner in preparation for and following compression-phase operations. Hydraulically actuated locking mechanisms carried by the upper platen permit the upper platen to be fixed to the posts so that the four large bore cylinders can be actuated to draw both the posts and the upper platen downwardly, as during compression of a work-piece between the platens.

Abstract: ABSTRACT     A continuous winder which produces individual rolls of sheet material having a high quality finish.  This is accomplished  by  maintaining  a  surface-winding  layon roller  in contact with each roll throughout the entire winding operation.  The winder is comprised of a support frame having a turret mounted therein which carries a plurality of  spindles onto which  the  individual  rolls are wound.  A double layon roller assembly is mounted in the frame so that one of the layon rollers is in contact with a first  spindle during the winding operation.   A length  counter  generates  a  signal  which  starts  the transfer  operation  when  a  roll  is  wound  whereupon  a second spindle is brought up to speed and a cutter is extended   adjacent the   sheer   of   the   material. Simultaneously, an auxillary layon roller is moved into contact with the second spindle.  Adhesive on the second spindle pulls the web onto the cutter starts the winding on the second spindle.  The cutter is retracted, and the turret  is  indexed  approximately  30°.   The  auxillary layon roller remains in contact with the second spindle during  this  indexing  while  the  primary  layon  roller remains  in  contact  with  the  first  spindle.   When the primary  layon  roller  clears  the  finished  roll,  the second primary layon roller moves into contact with the second spindle.  The auxillary layon roller is retracted and  the  turret  is  indexed approximately  an additional 60°  to  move  the  second  spindle  to  the  normal  roll buildup position.

Abstract: ABSTRACT OF THE DISCLOSURE         The present invention provides a cross-country vehicle for stepwise locomotion across terrain comprising a pair of hydraulically operated leg units at the front of the vehicle and a pair of wheels at the rear of the vehicle, the height of the wheels being adjustable which wheels` are hydraulically supported on longitudinal arms.  Motion of the vehicle is effected by app-ropriate movements made by means of hand levers and amplifiers. An on board computer automatically provides for a constant and substantially horizontal position of the vehicle cab and cons-tantly carriers out calculations to ensure that when one leg is raised the position of the centre of gravity is at that moment within the three support points.  Advantages of leg units are thus combined with advantages of wheels.  The command of the leg elements is greatly simplified since there are only two such units.  The vehicle is well suited as a vehicle platform for machinery used in forestry, due to its cross-country capability.

Abstract: BUFFERED STEAM DRIVE OIL RECOVERY PROCESS     ABSTRACT           Steam injected into a subterranean formation comprises a liquid phase and a vapor phase.  Oil displacement by the liquid phase is not as efficient as the oil displacement in the portion of the formation contacted by the vapor phase.  The effectiveness of the oil recovery process in the portion of the formation being contacted by the liquid phase is increased by contacting that portion of the formation with an aqueous solution containing from 0.005 to 2.0 percent by weight of an alkalinity agent, preferably sodium hydroxide and from 0.01 to 5.0 percent by weight of a buffering agent, preferably sodium carbonate.  The mixture of sodium hydroxide and sodium carbonate may be co-mixed with the steam introduced into the formation, or may be introduced as a separate liquid containing both the sodium carbonate and sodium hydroxide, or separate slugs containing sodium carbonate and sodium hydroxide may be injected.

Abstract: Abstract of the Invention A low profile safety floor for electrically powered mobile storage systems includes one or more elongated panels that span the building floor between the system rails.  To each end of the panels are mounted a pair of leaf springs and a safety switch. The panels are supported above the rails by means of the leaf springs.  When a person steps onto the safety floor, the panel is deflected downwardly so that a safety switch is actuated.  Positive stops limit the approach of the panel toward the rails.  Switch actuation deenergizes the electric motor drive powering the carriages.  To prevent panel sag, the panels are manufactured as wood and steel laminates.  To further inhibit sagging, the panels are forced into a permanently upwardly convex shape at manufacture.
