Abstract: Abstract Method And Apparatus For Flattening Corrugated Heat Exchanger Plates A method and apparatus (32) is provided for crushing a portion of a corrugated sheet (10) in an area (20, 22) extending transversely to the cor-rugations in the sheet without blocking the passages (14) between the crowns(12) of the uncrushed portions of the corrugated sheet (10).  In accordance with the method, spacing members (58-66 and 78-88) are inserted into each of the passages (14) on either side of a ridge (12) to be crushed, and the ridge (12) between the spacing members (58-66 and 78-88) is crushed before the spacing members (58-66 and 78-88) are withdrawn.  The apparatus for crushing the sheet (10) includes opposed die members (34, 36), each having a plurality of blades (58-66 and 78-88) spaced by slots (68-76 and 90-98).  The slots (68-76 and 90-98) in each die member (34, 36) progres-sively decrease in depth and are positioned to receive the blades (58-66 and 78-88) of the opposed die member. A control circuit (46) causes the die members (34, 36) to engage each time a passage (14) in the cor-rugated sheet (10) is aligned with a blade (58-66 and 78-88) in a die member (34, 36).

Abstract: ABSTRACT            In a  data  processing unit,  apparatus is  disclosed which permits  more than one  control  interface  unit to transfer data to an  input/output  multiplexer.   Thus, more than one central  processing unit   can have  access to a  peripheral subsystem. Apparatus  is   provided  which   causes  the input/output  multiplexer  to receive  sets of  data  signal groups from the control interface units in sequential order.          A  signal-free   period is  provided   by the  control  unit interface between  each set  of data  signal  groups  (e.g., comprising a  single  command  sequence)  which  allows  the input/output multiplexer to accept waiting data signals from the next sequential control interface unit.  Once begun, the transfer of the  entire set of data  signal groups will pro-ceed without interruption.

Abstract: ABSTRACT OF THE DISCLOSURE        A waste water treatment plant for carrying out an activated sludge treatment process in accordance with the invention includes an aeration basin capable of receiving a flow of waste water (which flow may be subject to temporary rate surges) and retaining a selected volume of the waste water.  The basin will in-clude suitable means for aerating a mixture of the waste water and activated sludge.  The plant also includes a settling tank adapted to receive the aerated waste water and activated sludge and to permit the activated sludge to settle downwardly toward the bottom of the tank.  Effluent outlet means are associated with the settling tank to allow the clarified effluent to escape therefrom.  Sludge return means are associated with the settling tank for withdrawing sludge which is settled toward the tank bottom and to return at least a portion of same to the aeration basin.  The plant includes means for pumping the aerated waste water and sludge mixture from the aeration basin to the settling tank at a selected rate such that the flow rate of the mixture into the settling tank is sub-stantially independent of the temporary surges in the rate of flow of waste water into the aeration basin.  This serves to reduce any disturbance to the settling of the sludge with the aeration basin typically accommodating volume changes due to any temporary surges in the flow of waste water thereinto.

Abstract: Abstract of the Disclosure An improved weighing apparatus includes a load receiving platform which is supported by a plurality of load cells.  Each of the load cells has a downwardly facing recess in which a floating pin is received.  The pin has a relatively large base which engages a floor or support surface and an upwardly projecting mounting section which extends into the recess in the load cell.  The pin has an arcuate upper surface which enables tilting movement to occur between the pin and the load cell to compensate for uneven floors,  In order to compensate for shifting movement of the plateform relative to the floor due to thermal expansion and other causes, the base of the floating pin is movable along the floor.  The mounting section of the pin is held in the recess in the load cell by a retainer plate which is fixedly connected with the load cell.

Abstract: ABSTRACT:           A current stabilizer equipped with field-effect transistors of the enhancement type. The stabilizer has two parallel current paths which are coupled by means of two different current coupling circuits in order to obtain a stabilizing point.  At least one of the two coupling circuits comprises two field-effect transistors which are each included in one of the two current paths. One of said field-effect transistors has a gate-source voltage which is a constant fraction of the gate-source voltage of the other transistor, which is achieved in that in series with said one transistor there is included a third field-effect transistor with interconnected gate and drain electrodes, so that the other one of said two transistors has a gate-source voltage which is twice as high as that of the said one transistor.  The other cur-rent coupling circuit is of the opposite conductivity type and may be a current mirror, but it may also be con-stituted by the complementary version of the one current coupling circuit.

Abstract: -ABSTRACT OF THE DISCLOSURE           An article of manufacture is disclosed for use in a projection television system.  A cathode ray picture tube has a face panel with a rearwardly extending skirt and a window for receiving a cathodoluminescent imaging screen.  The tube has a seal land which defines a plane whose normal makes a non-zero acute angle with respect to the axis of said window.          The article is for use in a system having a cathode ray picture tube whose projection optical axis is on the axis of a remotely located viewing screen, and at least one displaced axis cathode ray picture tube; that is, a tube whose projection optical axis is displaced from the axis of the viewing screen by a non-zero acute angle.  The method provides for compensating for the non-linear magnification distortion of the projected image caused by the displacement of the tube off the viewing screen axis.  The method also provides for the forming of the face panels and funnels of both the on-axis tube and the displaced axis tube by one pair of glass molds.

Granted: 1984-07-24
Abstract: "ELECTROPHORETIC PROCESS FOR SEPARATING AQUEOUS   MINERAL SUSPENSIONS" ABSTRACT OF THE DISCLOSURE An aqueous suspension of fine mineral solids, for example oil sand tailings sludge, is separated into separate solid and liquid components by first chemically conditioning the suspension with the addition of lime, and thereafter passing an electrical potential between electrodes submerged in the suspension.  The electrical potential causes the solids to migrate toward, and deposit on, the positive of the electrodes. The lime pre-treatment allows the electrode deposit to dry, through electroosmosis, to render it sufficiently dry by disposal.  The chemical conditioning step preferably includes adding a carbonate- or bicarbonate-forming reagent after the lime addition.
