Abstract: ABSTRACT OF THE DISCLOSURE A method and apparatus for processing and packaging cheese in which cheese curd which has been milled and salted is fed into four columns mounted on an upright tubular trunk fitted at the lower end with a guillotine blade movable between a closed position in which it closes the bottom of the trunk and an open position in which the blade is wholly clear of the trunk.  The columns are maintained at a sub-atmospheric pressure so that air in the curd is flashed off immediately the curd enters the columns.  The curd in the columns flows into the trunk and merges with the curd from the other columns to form a pillar of curd supported on the guillotine blade.  The walls of the columns are perforated for drainage of whey pressed out from the curd by the weight of superimposed curd.  An elevator below the trunk lowers the pillar of curd when the guillotine blade is withdrawn, the blade being subsequently returned to cut off a block of cheese from the lower end of the pillar.  The elevator lowers the block of cheese into an open-ended rectangular container lined with a tube of plastics material which is subsequently sealed and evacuated to enclose the block of cheese.

Abstract: PHN 9640                                      30.10.1980 ABSTRACT: Device for determining a radiation absorption distribution in a plane of a body.          The invention relates to a computer tomography device in which the detector device is asymmetrically arranged with respect to the connecting line between the X-ray source and the centre of rotation of the source and the detector device. The detector device produces an incomple-te profile of measuring values which are supplemented with "zeros" during the processing in order to form a number of measuring values of a complete profile. In order to avoid artefacts which are produced by the acute transients between measuring values and "zeros", a number of measu-ring values adjoining the acute transients are multiplied up to and around the centre of rotation by a factor so that from the "zeros" a "smoothly" increasing series of adapted measuring values is obtained which changes over in the "normal" or unadapted series of measuring values.

Abstract: IMPROVEMENTS IN BLOOD ACCESS SYSTEMS            ABSTRACT Improvements and accessories for a septum closed T-shaped blood access device adapted for implantation into a patient.  The implantable device has a stem portion extending above the skin of the patient and defining a septum closed opening into the device.          The improvements include an improved septum having a       groove in the side thereof encircling the septum and an elastomeric ring carried within the side groove, an improved needle assembly which provides access to the circulatory system through the septum, and a flexible cap for sealing the stem of the implantable device from the outside atmosphere which may be fitted in place or removed without the necessity of specialized tools.          One of the accessories is a septum assembly insertion tool which simultaneously inserts the septum, a pressure plate and a retaining ring into the stem cavity of the implantable device.  Another accessory is specialized forceps clamp for gripping the flanged upper edge of the stem of the implantable device.  The clamp has curved finger holds which permit the stem of the implanted device to be stabilized during insertion of the septum assembly.          Yet another accessory is a back-up septum system for plugging the cavity in the stem of the implanted device above the principal septum when the principal septum begins to fail.  The back-up septum system comprises a specially designed spacer member, a septum conforming generally to the shape of the stem cavity above the retaining ring for the principal septum and a specially designed clamp for holding and compressing the back-up septum within the stem cavity.  The back-up system permits continued access to the circulatory system until assistance can obtained in replacing the primary septum.          A final accessory is a hemispherical implant cap which protects the stem cavity of the implantable device during implantation of the device in the body.

Abstract: ABSTRACT      An ultrasonic system for sensing a liquid-fluid interface comprises a support structure (10) to which a transmitting crystal (21) and a receiving crystal (22) are bonded in such a way that the crystals (21 and 22) are positioned opposite each other across a gap (30). Each of the cyrstals (21 and 22) has a relatively high resonant frequency and a relatively low resonant frequency.  An amplifier means (40) and a bandpass filter means (50) are connected to the crystals (21 and 22) to form a feedback loop.  In normal operation, the transmitting crystal (21) is excited to resonate at its high resonant frequency in order to cause transmission of an ultrasonic signal across the gap (30) without causing appreciable ultrasonic transmission through the support structure (10) to the receiving crystal (22).  When it is desired to test the system for integrity in the absence of liquid in the gap (30), the transmitting crystal (21) is excited to resonate at its low resonant frequency and the passband of the bandpass filter means (50) is shifted to enable low frequency oscillations to occur in the feedback loop due to ultrasonic transmission (i.e., cross-talk) through the support structure (10) between the crystals (21 and 22).

Abstract: MI-2802 LOAD-LOCK VACUUM CHAMBER ABSTRACT An apparatus for etching one wafer while simultaneously pretreating or stripping another wafer. A module comprises a wafer etching chamber disposed within a larger chamber. The wafer etching chamber is adapted to etch a first wafer during the time that a second wafer is being pretreated in the larger chamber. When the first wafer is etched, it is transferred to the larger chamber and the pretreated second wafer is transferred to the etching chamber. During the time the second wafer is being etched the first wafer is stripped and removed from the larger chamber. A third wafer is introduced into the larger chamber for pretreating while the second wafer is being etched and the process repeated. Once a wafer enters the module for pretreating, etching and stripping, it is not exposed to the atmosphere until stripping is complete.

The passages are unevenly spaced to compensate for air pressure variations within the manifold, and provide a uniform volumetric distribution of outlet air around the manifold.  A cover extends across the manifold outlet passages, and air from the passages is directed through an annular opening defined by the cover to generate a shroud of air for movement, around, across and forwardly of the rotary head.  The shroud air aids in moving spray particles toward articles to be coated, while the particular shroud air structure provides a very uniform volumetric distribution of the shroud air.  Also, by virtue of the cover extending across the manifold passages, the passages are not subject to clogging by spray particles.
