Title: Apparatus for combining sheet-like products
Inventor: MEIER JACQUES
IPC: B65H39/075
Filed: 1996-10-28
Granted: 1999-06-01
Abstract: The apparatus has a plurality of carrying elements (20) which are arranged at a distance one behind the other on a drawing member (14), driven in the circulating direction (U).  The longitudinal direction (L) of the carrying elements (20) extends at an acute angle (.alpha.) with respect to the circulating direction.

Abstract: A method of storing a procedure in a data processing system to direct a telephone network to provide requested services to a customer.  The method involves invoking a display level software process for converting a graphical representation level of display information that is a visual representation of the procedure into a data structure level representation of the procedure.  A data structure level software process for converting the data structure level representation of the procedure into a binary representation of the procedure is then invoked.  In the final step a binary level software process is used for storing, in a code level, executable code to implement the requested services. The executable code corresponds to the data in the data structures.

Filed: 1997-11-21
Granted: 2001-07-31
Abstract: A static electricity dissipation garment where the body of the garment is constructed of fabric within which is woven strands of carbon.  The body will be constructed as a smock or as a pant suit.  The pant suit garment includes a pair of side seams located between the torso section of the garment and down each leg section of the garment.  The smock includes a similar pair of side seams in the torso section.   A first embodiment of the garment includes sleeve seams that extend along the entire length of each sleeve of the garment and then along the connection of the sleeve to the upper part of the torso section and then along the collar of the garment.  Within each of these seams, along the entire length of the seam, is included an electrically conductive ribbon.  The ribbon of the side seam is designed to overlap a substantial length of the sleeve seam.  The ribbons of the two sleeve seams and side seams overlap each other in the area of the collar.  An appropriate electrical connector is connected to the ribbon of at least one side seam.   An electrical conductor is to be connected to the electrical  connector  which  is  to  function  to  remove  static electricity that accumulates on the garment.  A second embodiment of garment has each side seam extending down each sleeve and terminates at the cuff.  Transverse ribbons are mounted across the torso section of the first embodiment, second embodiment, smock and pant  suit  garment  which  provide  a  dual  pair  of  electrical connectors each of which may be used to remove static electricity by being connected to an output electrical conducting grounding wire.  Boots and gaiters could be manufactured to include similar electrically conductive ribbons and hence be dissipative of static electricity.

Abstract: In the terrestrial transmission network infrastructure, test lines and videotext are already carried mainly in the picture-free lines. Additional wireless services often fail as a result of the high cost of television studios and a shortage of frequencies. The present invention accordingly aims to make even fuller use of unused channel capacity in a TV channel for additional signals. At both the transmission and receiving ends, the signal pulses for additional video and audio data to be transmitted are formed from the FBAS useful signal by counting, evaluation and decision operations. The two signals are separated, digitised, stored, buffered and compressed at the transmission end before being superimposed on the useful signal. At the receiving end, following identical signal pulse generation, the same steps are executed in reverse order. The procedure can be carried out at the transmission end using additional equipment and at the receiving end by computer software or additional devices installed in the TV set. The procedure can be used for any additional picture and sound signals. A preferred special application is a communal picture broadcast in the manner of a slide demonstration.

Abstract: The invention is directed to a masonry anchor for tying a masonry veneer wall to a stud back-up wall having an outer covering, the anchor comprising a generally planar anchor plate having an outer coupling end for connection to a veneer tie wire and an inner anchoring end for securement to the back-up wall. In one embodiment, the anchor plate has struck-out tabs extending laterally from the anchor plate, intermediate the coupling end and the anchoring end.      The outer coupling end of the anchor is insertable through a slot opening cut into the outer covering adjacent a stud in the back-up wall until the tabs engage the outer covering of the stud back-up wall to provide for proper spacing of the coupling end from the back-up wall. In a second embodiment of the masonry anchor, at least the outer coupling end is of a corrosion resistant material.

Title: Ameliorations concernant des soupapes
Inventor: ORBELL JOSEPH ROBIN
IPC: F16K31/20
Filed: 1996-08-02
Granted: 2007-05-29
Abstract: L'invention concerne une soupape qui, dans un cas, constitue une soupape d'admission (60) et, dans un autre cas, une double soupape de vidange (2). Les soupapes, qui peuvent être utilisées dans diverses circonstances, sont particulièrement adaptées à un réservoir de chasse dont l'eau s'évacue dans une cuvette de W.-C. ou dans un élément semblable. La soupape (2) comprend un tuyau de chasse (100) ou deux tuyaux de chasse (14, 18) pouvant se déplacer le long de leur axe. Une extrémité des tuyaux (100, 18) est solidaire d'un élément d'évacuation (9). Les tuyaux comportent des anneaux ou colliers (16, 22) qui, prenant contact avec les bords d'arrêt (48, 50) de flotteurs (40, 44), commandent le déplacement des tuyaux (100, 14, 18). Les flotteurs (40, 44) sont excentrés ou se trouvent dans une position qui les éloigne de leur centre de gravité de telle façon qu'ils puissent se mouvoir librement par gravité ou par la poussée due à leur pouvoir flottant. En cours de fonctionnement, en raison des effets alternés de la gravité et de la flottabilité, les flotteurs maintiennent les tuyaux en place puis les déplacent, ce qui leur donne des positions sélectives de chasse.

Title: Commercial production of aprotinin in plants
Inventor: BASZYCYNSKI CHRIS
IPC: C07K14/81
Filed: 1996-10-31
Granted: 2010-05-25
Abstract: A method for commercial production of aprotinin entails heterologous expression of the protein in plants, preferably at a level such that aprotinin accounts for at least 0.1 % of the total extracted protein. An aprotinin-expressing plant also has potential of increased insecticidal resistance by virtue of producing the protein. A genetic map of the integration locus allows identification of plants derived from the transgenic plant. This approach also reveals genetic loci on a plant chromosome that support high levels of gene expression and can be used as site of integration for expression of other genes of interest.

Inventor: WONG DANIEL Y
IPC: H04L47/765
Filed: 1998-07-14
Granted: 2002-04-02
Abstract: The invention provides a method for communication between a plurality of stations in a communication network using media access protocol, in which medium access is granted to stations obtaining a successful reservation of the medium and in which data transmission verification is performed by the protocol within the reservation. In the method a station sends a request message on the communication medium for a reservation of the medium to a recipient station in the network. The recipient station sends a reservation confirmation message back to the sending station which receives it and responds to the reservation confirmation message by sending an ordered sequence of data frames to the recipient station. After sending the ordered sequence of data frames the sending station sends an end of transmission message to the recipient station, which replies by sending back an end of transmission confirmation identifying the number of frames received in their original sequence. If the number is not correct remedial action can be taken by the sending station to resend missing data. Address conflict resolution is also provided by another aspect of the invention. The invention has embodiments which handle unicast and groupcasting transmissions.
