Abstract: ABSTRACT OF THE DISCLOSURE       A novel seal arrangement is provided for use in processing apparatus of the type including a partition for separating zones of relatively high and low pressures. At least one aperture is provided in such partition, the aperture having a wall.  A processing unit (such as a hydrocyclone) has a portion thereof located in such aperture so that an annular region is defined between such unit and the aperture wall.  An annular seal of resiliently deformable material is located in this annular region and provides a seal between the above noted zones.  This seal is of cup-shaped form and includes an annular outer seal lip which is radially spaced from the processing unit.  This seal outer lip is connected to the remainder of the seal via an end wall.  The seal outer lip has inner and outer surfaces and a free annular edge remote from the end wall.  This inner surface is exposed, in use, to the zone of higher pressure such that the outer surface of the seal lip sealingly engages the wall of the aperture under the influence of the differential pressures acting on it.  The seal is located relative to the wall of the aperture and the wall of the aperture is of such dimension that the sealing engagement between the wall and the outer surface of the seal lip occurs in an annular sealing region located generally between and spaced from both the seal end wall and the free annular edge of the seal lip.  Also provided is a hydrocyclone cannister arrangement employing a plurality of spaced apart flat horizontally arranged partitions.  The hydrocyclones are disposed in the apertures provided in the partitions described above with the accept, feed and reject openings all located in respective horizontal planes thus providing the hydrocyclones with identical operating pressures. The cannister arrangement may be conveniently accessible on a low horizontal level.  By providing a lid on the cannister the reject openings of the hydrocyclones may be easily inspected by removing the lid from the cannister.

Abstract: ABSTRACT OF THE DISCLOSURE:          During a change in casting parameters, particularly during displacement of a mold wall to change the strand format or cross-sectional shape, the supporting action and the cooling capacity should not fall either below a well-defined supporting action and a predetermined cooling capacity in order to avoid metal break-out or other defects in the cast strand.  Further-more, upon changing the strand cross-section the rate of adjus-tement should be increased in order to reduce the length of transitional pieces between the old strand format and the new strand format.  To achieve this result it is contemplated to bend the mold wall, during  displacement thereof into each pivotal position thereof, this bending of the mold wall corres-ponding to the instantaneous geometric shape of the moving solidified shell or skin of the strand and such bending is re-presentated by bending lines.

Abstract: ABSTRACT OF THE INVENTION        A composite container is disclosed having a synthetic plastic end closure member spin-bonded to the thermoplastic synthetic plastic inner liner layer of a composite container body wall. The synthetic plastic end closure member includes annular downwardly depending inner fin and outer chime portions which are concentrically spaced to define therebetween an annular groove.  One of the body and end members is rotated relative to the other member when they are in spaced vertical alignment, whereupon the members are axially displaced together to wedge the upper end of the body member into the annular groove of the end closure member.  During this spin bonding process, the fin portion of the end closure member is supported against radial inward deflection, whereby the spinning frictional engagement between the fin portion of the end closure member and the inner liner layer of the body member causes softening and subsequent bonding of the fin portion to the inner liner layer.

Abstract: LASER SYSTEM          Abstract of the Disclosure A laser system adapted for ophthalmological use includes a closed spherical pump cavity having a diffuse reflecting surface, and a laser crystal and an exciting flashlamp are mounted in non-parallel fashion in the cavity  The laser crystal is configured in an unstable resonator by a concave rear mirror and a convex front output mirror.  A Q-switch is interposed between the crystal and one of the mirrors to permit Q-switched and non-Q-switched operating modes.  A low power, continuous output, visible light laser is directed through the rear mirror and the laser crystal to provide a pilot beam for aiming and focussing.  The laser outputs are directed to a focussing system through a slit lamp biomicro-scope, and both are directed into the eye of a patient.  A laser power supply includes a plurality of capacitors arrayed in banks and controlled by a microprocessor to deliver pulses of preselec-ted voltage to the flashlamp singly or sequentially to produce single pulses, bursts of pulses, or repetitive pulses on command.          A control system also operates the Q-switch in synchronism with the flashlamp, when Q-switching is desired.  The system may be run in a thermal mode in which the laser crystal is stimulated by closely spaced repeated lamp flashes to cause the stimulated electron population inversion to be maintained.  The resulting long train of pulses within a predetermined time-power envelop closely mimics a continuous beam end produces the thermal physio-logical effects which are desirable for some laser surgical proce-dures.  In the Q-switched mode, the combination of microprocessor control, a short optical pumping cavity, an unstable resonator configuration, and a small diameter, short length, high gain crystal produce very narrow pulses of high intensity, high beam quality, and precise duration, spacing, and energy.
