Abstract: ABSTRACT PURIFYING MIXED-CATION ELECTROLYTE An electrolyte containing 65 g/l zinc and 150 g/l Cu is purified in zinc, that is, the copper is removed, by causing the electrolyte to fluidise a bed   of ? mm copper particles.  The bed is fluidised by 25% to make it 42 cm deep.  An anode   is disposed above the top of the bed.  A cathode   is disposed part-way up the bed. Copper is electroplated onto the bed particles.  Any zinc which may be electroplated onto the bed particles tends to redissolve with concomitant cementation, on the particles, of copper, which can be recovered.  The electrolyte is thus eventually completely stripped of copper and can be used for zinc electrowinning.

Abstract: ABSTRACT;  IMPROVED HEAT TRANSFER APPARATUS          A heat transfer plate for heat.transfer apparatus, such as heat exchangers or evaporators is disclosed which is at least partially bounded by a groove 32 for receiving a gasket for general conformity therewith and to seal against an adjacent plate, wherein; the groove comprises an inner side wall and an outer side wall;  the outer side wall of  the groove is provided with a number of lateral bays 30,  the gasket being formed with a number of  corresponding  spaced  projections  engaging  in  and matching with said bays: the base 33 of each bay is at a level other than the base 34 of the groove, and; each bay  30  does  not  communicate with the ambient thereby limiting movement of the gasket material along each said bay.            The embodiments of the invention have a common feature that  the  gasket  sealingly  engages  the  rear  wall  27.          This engagement limits extrusion of the gasket material along  the  bay  of  the  groove  and  thereby  prevents "blowing-out"   of   the   gasket   at   these   points.   Furthermore the floor of the bay, 40 is at a level other than the floor  of  the  groove  34.   This difference in level  aids  engagement  between  the  gasket  and  the heat-transfer plate.          Figure 6

Abstract: PROCESS FOR HIGH-SPEED PRODUCTION OF WEBS OF DEBOSSED  AND PERFORATED THERMOPLASTIC FILM                         ABSTRACT The present invention provides for a process for debossing and perforating a substantially continuous web of substantially planar thermoplastic film, using a forming structure having a patterned forming surface with holes and an opposed surface. The forming structure is open from the holes in the forming surface to the opposed surface. The web of film has an indefinite length, a first surface, a second surface, and a thickness which is the distance between the first surface and the second surface. The process comprises the following steps:     (a) The web of thermoplastic film is provided with its first surface proximate the forming surface of the forming structure. The forming structure moves in a direction of the length of the web of film and carries the web of film in that direction. The web of film is substantially entirely molten. (b) A fluid differential pressure is substantially continuously applied across the thickness of the web of film from a first position along the direction of movement of the forming structure to a second position. The first and second positions are fixed relative to the moving forming structure. The fluid differential pressure is sufficiently great to cause the first surface of the web of film to be urged against the forming surface and to cause perforations to be created in the web of film. Thus a web of debossed and perforated film is formed in the image of the forming surface from the web of film. The web of debossed and perforated film has a first surface and a second surface which correspond to the first surface and the second surface, respectively, of the web of film. Fluid differential pressure holds the web of debossed and perforated film against the forming surface. (c) The second surface of the web of film is contacted with a fluid having low heat transfer capacity for a period of time from when the web of film passes the first position through when the web of film is debossed and perforated. Thus, the web of film remains substantially entirely molten throughout this period of time. (d) Cooling fluid is applied to the second surface of the web of debossed and perforated film after the film is debossed and perforated and before the web of debossed and perforated film passes the second position. Thus the web of debossed and perforated film is cooled and is set by the time the web of debossed and perforated film passes the second position.

Abstract: Abstract:         In an acoustic microscope an ultrasonic beam is projected onto a sample through a propagating medium by an ultrasonic transducer having a short focus.  Reflected acoustic waves from the sample are detected by the transducer, and a microscopic image of the sample is obtained by scanning the sample mechanically in two dimensions.  The invention provides a cover member interposed between the sample and the propagating medium and having an acoustic impedance higher than those of the sample and medium.  The intensity of the reflection signal depends upon multipath reflection within the cover member, and an intense reflection signal is obtained even for a sample that differs only slightly in acoustic impedance from the propagating medium.  This enables such a sample, e.g. biological tissue, to be examined with a high signal-to-noise ratio in an acoustic microscope of the reflection type, whereas in the past this has necessitated the more complicated transmission type.

The use of pincer-type gripper systems in the turning cylinder guarantees that the back edge of the sheet is guided without bending throughout the entire turning process. All printing units, even those which are convertible to a turning apparatus, exhibit identical side parts.

Abstract: ABSTRACT   A system for measuring the friction between the bottom two sheets of the stack. The bottom-most sheet is held to a vacuum corrugation feeder tray by any suitable means such as a vacuum and moves with the tray. The vacuum corrugation feeder tray is mounted on compliant supports and driven near or at its resonant frequency by an electromechanical driver. At low or zero air knife pressure, the paper stack is mechanically coupled to the tray and moves with the tray, possibly slipping at some point during the vibration cycle. As the air knife pressure increases, the mechanical coupling decreases, and a point is reached at which the stack remains stationary. Prior to the point where stack motion ceases, the resonance of the tray is modified and it is possible to estimate the weight of the stack. When the stack motion ceases, the frictional force F can be estimated from the driving force required to maintain a given vibrational amplitude. From the driving force required to maintain a given vibrational amplitude and the mass of the tray or stack, it is possible to calculate the coefficient of friction between the bottom two sheets. The coefficient of friction is then used to control the amount of air pressure from the air knife until an optimum coefficient of friction is achieved.
