Abstract: ABSTRACT OF THE DISCLOSURE       An improved system for selecting interface circuits on a priority basis and applies, in particular, to communication controllers.  More particularly, the invention relates to means for controlling the transfers of data via adapters on a priority basis.  The system interconnects that make requests for services at differing priority levels and contains a central processing unit including a lens characterized in that it includes dividing the interface circuits into subgroups of a first pyramid stage each provided with an asynchronous preselection of the inter-face circuit which has the highest priority level within each of the subgroups and an interfacer for each of the subgroups that make up the first stage using one of the interface circuits to make up a second stage of the pyramid.

Abstract: 1                   PHN. 9261.            ABSTRACT:           A low-pressure mercury vapour discharge lamp having a lamp envelope which encloses a folded tubular discharge vessel, the discharge vessel being provided with an appendix which is kept at a relatively low temperature by a heat shield located within the lamp envelope.   The heat shield shields the outer wall sur-face of the appendix from the outer wall of the discharge vessel.  The cooler appendix serves to main-tain the mercury vapour pressure at an optimum value during operation of the lamp.  No additional measures are required in order to control the mercury vapour pressure in the discharge vessel.

Abstract: CLAMPING APPARATUS FOR USE WITH A MULTI-STATION PACKAGING            MACHINE OR THE LIKE Abstract of the Disclosure An improved multi-station machine is disclosed for assembling ring-type closures from generally cylindrical paperboard cylinders and generally circular paperboard discs.  The machine employs a rotatable dial plate, carrying eight mandrels and an improved ring clamping system, which dial plate is incrementally rotated by an automatic indexer assembly relative to the various operating stations which consist of a ring feed station, a disc feed station, an adhesive dispensing station, a curling station, a grooving station and a closure ejecting station. Means are provided for controlling the operation of the various stations so that they operate in substantial synchronism with one another and with the rotatable dial plate.  The improved disc feed station automatically feeds the lowermost disc from a stack of discs to a position over a ring on the dial plate and simultaneously forms a peripheral skirt on the disc and positions it in an open end of the ring.  The adhesive dispensing station employs a pair of tube pumps to dispense adhesive and lubricant on partially  assembled  ring-type  closures.   The  grooving  station automatically forms a peripheral groove and a corresponding radially inwardly extending rib in the cylindrical wall of an assembled ring-type closure.   The  closure ejecting station provides vacuum means  for withdrawing a completed closure from a mandrel on the dial plate and pressurized air means for assisting in the automatic removal of the closure from the mandrel and for automatically propelling the thus removed mandrel from the machine.  The ring feed station provides means for preventing the introduction of rings onto the dial plate in response to an indication of insufficient discs at the disc feed station.  Control means are provided for manually indexing the dial plate as well as prevention of disc feed, and adhesive and lubricant dispensing if an appropriate ring is not present on the dial plate, as well as control means for preventing ring feed if sufficient discs are not available at the disc feed station. Various other control features are disclosed for the prevention of operator injury, material waste and machine jamming.

Title: Method and system for freeze-stabilizing wine
Inventor: RIESE HANS M
IPC: C12H1/00
Filed: 1980-08-07
Granted: 1982-09-07
Abstract: A method for freeze-stabilizing wine and a system for carrying out this method are described.  The method is of a type in which the wine is first chilled so that ice crystals are formed in the wine while the wine is still pumpable, whereupon the wine is conveyed to a residence tank in which tartrate crystals are formed.  The wine is then heated to melt the ice crystals, whereupon the tartrate crystals formed are removed from the wine.  The method according to the invention is characterized in that the wine is conveyed continuously to and from the residence tank, where the wine is agitated in such a way that there is maintained a homogeneous suspension of ice crystals and tartrate crystals in wine.  It is advantageous to stir the wine with a horizontally pivoted stirrer which rotates at a relatively low speed.  Suitable operating conditions are obtained if the wine is first chilled to a temperature which is 0.2 to 5.degree. C below the freezing point of the wine, and if the residence time in the tank is 15-150 minutes as an average.

Abstract: HALF-DUPLEX/SIMPLEX DIGITAL SIGNAL CONVERTER     Abstract A solid state circuit, which serves as a twin simplex/ half-duplex converter, includes a triple input NAND gate. The output of the NAND gate is connected directly to the outgoing simplex conductor.  Signals on the incoming simplex conductor are applied to the three inputs of the NAND gate through separate signal paths which introduce different delays.  One signal path introduces an interme-diate delay before applying the incoming signal to the NAND gate in an inverted form.  The half-duplex line is connected to this signal path.   While incoming signals are applied at all three inputs to the NAND gate as well as to the half-duplex line, a lack of coincidence at the inputs prevents any incoming signal from passing through the converter to the outgoing simplex line.

Abstract: APPARATUS FOR PRODUCING MICROFORM RECORDS       FROM MULTIPLE DATA SOURCES                 Abstract of the Disclosure Apparatus for producing microform records from various image sources, such as hard copy or cathode ray tube images fed from various data sources,includes an image-reducing projection system into which is selectively directed light selected from hard copy or light preferably from the face of a cathode ray tube to which white background CRT image-forming signals are fed from any one of a number of selectable data sources.  The reduced image involved is preferably applied first to a non-archival heat developable mask-forming film, like a dry silver film, and then the image on this film is transferred preferably to an archival film capable of later receiving additional data on unused portion thereof and most advantageously arranged as a microfiche card. A cathode ray tube image providing means is located immediately below a platform-containing or receiving image field area.  The platform normally is adapted to receive hard copy thereupon.          Manual controls are provided for setting-up the apparatus for producing microform records of either hard copy or cathode ray tube face images.  In the latter case, the platform, which is preferably white opaque, is moved to expose the image providing means the light image thereon is directed up into the image-reducing projection system.  Means are provided for deter-mining exposure times for imaging upon the mask-forming film in accordance with the average background light intensity of the light reflecting from the hard copy or the background light on the cathode ray tube image, depending upon whether hard copy or cathode ray tube image microform imaging is desired by operation of the appropriate manual controls.
