Abstract: MULTIPLE DEPTH BUFFERS FOR GRAPHICS AND SOLID MODELLING           ABSTRACT OF THE DISCLOSURE          A CSG solid modelling system 10 has a triple z-buffer architecture. For each pixel stored in a pixel memory 12 there are five storage entries grouped into five buffers including a front z-buffer (F)  16 which is employed to store  the  depths  of  a  front  face  for  a  currently processed z-connected product,  a back z-buffer  (B)  18 which is employed to store the depths of a back face for the currently processed z connected product and a final z-buffer  (Z)  20  which  stores  the  front  faces  of  a displayed  solid.  Two  other  buffers  are  an  intensity buffer (T) 22 for storing the intensities associated with the front face of the current z-connected product and a final intensity buffer (I) 24 for storing the intensities of the visible faces of the displayed solid. A bus 26 couples these various buffers together and to a processor 28 which may be a central processing unit or a peripheral processor. The system provides for a solid represented by any CSG tree to be represented as a union of z-connected products and that these z-connected products be expressed as intersections of z-connected sweeps.  Furthermore it is shown that expressions of z-connected products in terms of  sweeps  are  extracted  directly  from  a  CSG  tree. Variations of the display methods may be used to detect interferences and differences between solids defined in CSG.

Title: Substituted phenyl polybenzimidazole polymers
Inventor: SANSONE MICHAEL J
IPC: C08G73/18
Filed: 1990-01-30
Abstract: (h)  Abstract of Disclosure This  invention   discloses  a  unique  process   for   the preparation of  N-substituted phenyl  polybenzimidazole  polymers from unsubstituted polybenzimidazole polymers.  An  unsubstituted polybenzimidazole polymer is first reacted with an alkali hydride to produce a polybenzimidazole anion which is then reacted with a substituted  or  an  unsubstituted  phenyl  fluoride  to  produce N-substituted    phenyl    polybenzimidazole    polymer.      The N-substituted phenyl polybenzimidazole  polymer produced by  this process can be  formed into  a wide  range of  products, such  as membranes, films resins or fibers.   The produce can be  designed to meet special  applications by the  choice of the  substituent.          These N-substituted  phenyl  polybenzimidazole  polymers  can  be utilized for  numerous  applications including  reverse  osmosis, ultrafiltration, microfiltration,  electrodialysis, ion  exchange and affinity chromatography.

Abstract: Abstract The  invention  relates  to  a  travelling  centralizer arrangement  in  a  rock  drill  (2),  comprising  a travelling centralizer (5) movable along the feeding beam (1) during the drilling. The travelling central-izer (5) of the arrangement comprises two jaw halves (12a, 12b) mounted in a carriage (8) provided for the travelling  centralizer  so  as  to  be  pivoted  about journals (13a, 13b) parallel to the feeding beam (1). Each jaw half (12a,  12b) comprises a wheel (9a,  9b) moving along the guideways (10) of the feeding beam (1)  and keeping  the  jaw halves  (12,  12b)  pressed against each other during normal  drilling  so that jaws  (14a,  14b)  form a drill rod centralizer con-centric with the drill rod (4).  The guideways (10) comprises at the forward end of the feeding beam (1) a  portion  (L)  which  extends  downward  from  the straight  guideway  portion.   When  the  travelling centralizer reaches this downwardly extending guide-way portion, the wheels (9a, 9b) are displaced down-ward along the surface of the guideways, so that the jaw halves (12a, 12b) are pivoted about the journals (13a, 13b), thus drawing the jaws (14a,  14b) of the travelling centralizer apart from each other so that the chuck (3) is able to pass therethrough.

Title: Apparatus for preparing hot beverages in a microwave-oven
Inventor: CREYAUFMULLER PETER
IPC: A47J31/54
Filed: 1990-05-18
Abstract: ABSTRACT OF THE DISCLOSURE     An  apparatus  of  simple  design  for  preparing  hot beverages in a microwave oven is disclosed in which a flavouring  agent  comes  into  contact  exclusively  with adequately heated water.  The apparatus comprises a fresh water container with a bottom which is adapted to be placed upon a receptacle for the prepared hot beverage.  The fresh water container is equipped with a siphon-like overflow pipe.  The inlet opening of the overflow pipe is located inside the fresh water container, and the outlet opening passes through the bottom of the fresh water container and opens into a connecting element projecting downward from the bottom of the fresh water container.  In one embodiment the fresh water container is airtight when closed while the receptacle can be aerated and deaerated.   Water in the fresh water container, when heated in the microwave oven, produces an overpressure in the container.  This forces the heated water through the overflow pipe and out of the fresh water container.   In another embodiment the fresh waker container is aerated while the receptacle can only be deaerated.    This  produces  a  partial  vacuum  in  the receptacle.   The negative pressure  in  the  receptacle suctions the heated water from the fresh water container through the overflow pipe.

Patent CA-2023501-A1 (CA)
IPC: B65B69/00
Filed: 1990-08-17
Abstract: An apparatus for opening plastic bags to remove their contents has a pair of wheels mounted in approximate coplanar relationship such that there is a point of approximate cotangency. The two wheels rotate in opposite directions, and a series of tines are mounted in spaced relation on the periphery of each wheel to extend normal to the direction of travel of the loop. Once a filled plastic bag is placed onto the apparatus at the point of approximate cotangency of the wheels, a biased flexing structure presses the bag against the tines. A hole is created in that surface riding on the tines as the tines move away from the point of approximate cotangency.  To remove any articles remaining in an opened bag, a pair of oppositely-rotating rollers are positioned so as to draw the bag between them.  An oscillating member forward of the rollers acts to prevent any articles remaining in an opened bag from entering between the rollers.  A vacuum collection means draws off the emptied bags.  The apparatus has particular application to the opening of bags containing recyclable articles.

Title: High definition television arrangement with signal selections adapted to the available transmission capacity
Inventor: KNAUER SCOTT C
IPC: H04N19/94
Filed: 1991-03-07
Abstract: A HIGH DEFINITION TELEVISION ARRANGEMENT WITH SIGNAL SELECTIONS ADAPTED TO THE AVAILABLE TRANSMISSION CAPACITY Abstract A high definition television system that is characterized by low transmission bandwidth is achieved by removing redundancies in the signal, encoding the remaining signals, and transmitting the encoded signal in a manner that is most compatible with the applicable standards. In the encoding, groups of signals to be sent are mapped to codebook vectors and the identities of the codebook vectors are sent together with those signals of the groups of signals that correspond to the codebook vectors. To insure that the total number of signals that are sent does not exceed the available capacity, the signals are sorted by a selected importance parameter and assigned for transmission in descending order of importance until the capacity is exhausted. Signals that are not assigned for transmission are discarded.

Abstract: A multiplex-packet band learning system and method wherein management of the transmission band of a trunk suit-able for an actual packet communication amount can be estab-lished to contribute to efficient multiplex packet communica-tion.  The number of communication packets per unit time for each medium pattern corresponding one of combinations of call terminal attributes is measured for the trunk interface of each exchange, a normal distribution of the numbers of commu-nication packets in actual communication is estimated on the basis of the measured number of communication packets per unit time for each medium pattern, and its estimated value is updatingly held as index data of permission or prohibition of a new call registration.  The number of communication packets in the actual communication is measured at a terminal inter-face so that a terminal band table for the terminal interface has packet rates at which the terminal has been so far commu-nicated, mean and variance values of the past packet rates are calculated on the basis of the actually measured number of communication packets, a normal distribution is estimated at PPLs of a controller with use of its measured statistical data, and it is judged whether the packet communication of a call requiring the registration to the corresponding trunk line is permitted or prohibited.
