Title: Process for the manufacture of friable silicon nitride bodies
Inventor: WILLKENS CRAIG A
IPC: B02C19/18
Filed: 1990-10-12
Abstract: ABSTRACT OF THE DISCLOSURE       A friable silicon nitride body is prepared by infiltrating a non-friable silicon nitride body with a fluid which expands upon freezing, rapidly freezing the fluid, and thawing the fro-zen fluid.  Silicon nitride flakes and chunks obtained with only light pressure on the friable body may then be final milled to a desired particle size more rapidly and with less energy input than with conventionally processed silicon nitride.  The silicon nitride body may have a higher density than has previously been used to prepare silicon nitride powders, thereby preventing the generation of potentially hazardous whiskers in the final powder product.

Patent CA-2036050-A1 (CA)
Title: Nonwoven fabrics for printing
Inventor: UMEZU NORIO
IPC: D04H1/64
Filed: 1991-02-08
Abstract: A nonwoven fabric, particularly composed of long-stock synthetic resin yarns such as polyethylene and polypropylene is provided at one or both surfaces thereof with an inksetting layer formed by coating, drying and curing a resin composition containing some of acrylic resins, synthetic rubbers and polyester resins.  The ink-setting layer is excellent in the transfer property and fixing ability to an oil ink which is ordinarily used for offset printing, and prevents the nonwoven fabric from being swelled or transformed by a petroleum high-boiling-point solvent contained in the oil ink.  Preferably, a low-temperature cross-linking agent is incorporated with the resin composition of the ink-setting layer so as to complete cross-linking of the resin composition at a low temperature at which heat shrinkage or heat damage of the nonwoven fabric will not be caused, in a shortened period of time.  Moreover, when 10 to 40% by weight of non-calcined clay, 1 to 15% by weight of titanium dioxide and 1 to 10% by weight of calcium carbonate or calcined clay are incorporated as fillers in the resin composition of the ink-setting layer, the ink-setting layer has improved absorbability, drying ability and fixing ability to a printing ink.  A preferable construction of the nonwoven fabric has a first layer containing the low-temperature cross-linking agent and a second layer containing the specific filler ingredients.

Title: Composite cap including tamper indicating feature
Inventor: VERCILLO PETER A
IPC: B65D55/08
Filed: 1991-02-14
Abstract: ABSTRACT OF THE DISCLOSURE            This  relates  to  a  composite  closure  which incorporates  the conventional closure of the press-on, twist-off  type including a metal shell having in the center  of  an  end  panel  thereof  a  tamper indicating button.  The  composite  closure  includes  an  overcap which  is  frictionally  interlocked with the shell and wherein the shell has been modified so that the curl at the  lower edge of  the skirt  thereof is outturned as opposed to being inturned and the rougher coating for receiving the sealing compound increases the frictional connection  between  the  overcap and the metal shell.          In  addition, the  overcap  is  provided  with a tamper indicating band which is interlocked with the container finish so as to prevent both axial upward movement and circumferential movement  of the tamper indicating band relative    to  the container  finish.  This permits, with controlled tolerances, an interlocking relation between the  composite closure and  the container wherein when the composite closure is twisted to remove the same the tamper  indicating  band  will  be  first  released  and thereafter  the  seal between  the  closure  and  the container  is broken and  the tamper indicating button will  pop-up in a normal manner.

Title: Method of reducing the risk for poor reception in a time multiplexed radio communication system
Inventor: DAHLIN JAN E A S
IPC: H04B7/06
Filed: 1990-07-19
Abstract: ABSTRACT OF THE DISCLOSURE            A method for reducing the risk of poor reception in a time multiplex radiocommunication system which includes at least one fixed station and at least one mobile station, when transmitting from one of the fixed stations to one of the mobile stations, as a result of the reflection of transmitted signals  against different objects. Transmission is effected in the fixed station from two antennas (19, 20), each of which receives signals from a respective branch. The signals in the two branches have mutually the same frequency and the same information content, but the phase position of one signal in one branch is changed (13, 14) in time, e.g. by phase jumping, in relation to the phase position of the signal in the other branch. In this way, any so-called zero points which may be present are moved geographically, i.e. points with no or with low signal strength. More than two antennas can be used in the fixed station for transmitting signals whose phase positions all vary mutually in time.

The detachable point is removed from the cannula and a guide wire with implant material attached is drawn out of the proximal end of the hollow body until the implant material is exposed at both the distal and proximal ends of the hollow body. Thereafter, the cannula is withdrawn from the tissue leaving the implant material in place and the implant material is anchored to reapproximate or reinforce the defect.

IPC: G11C7/00
Filed: 1992-03-27
Abstract: A circuit managing numbers of accesses to logic resources, such as buffer memory data cells in a time switching system. The circuit is structured around a counting cell matrix.  Each counting  cell  includes  a  synchronous  counter  storing  an instananeous number of accesses relating to a corresponding data cell of the buffer memory.  This encoded access number is representative of the number of outgoing multiplex ways from the  system to which a data  block received on  an  incoming multiplex way in the system must still be diffused. A given circuit operating cycle includes the loading of a counter by an access  number  corresponding  to  a  free  data  cell  address, supplied by matrix column and row encoders during a  cycle preceding  the  given  cycle.    This  loading is  obtained  by selecting a column and row by cell-to-be-charged column and row decoders, and by applying the encoded access number to an input bus of the counters in the cells. Simultaneous to loading, an updated encoded number of a counter in a second matrix cell is decremented by one unity in response to the read-out address applied  to  cell-to-be-decremented  address  column  and  row decoders  when  the  buffer  memory  cell  corresponding  to  the second cell is being read.
