Title: Shoe press belt
Inventor: ISHINO ATSUSHI
IPC: D21F3/00
Filed: 1998-02-25
Abstract: A shoe press belt is disclosed. The belt has both sides coated with a resin layer. At least one resin layer has side edge portions softer than the middle portion. The hardness of the edge portions may first decrease stepwise laterally outwardly from the middle portion to a section which overlies the shoe edge, and then increase stepwise laterally outwardly to the belt edge. A first stepwise reduction in hardness may begin laterally inward of the wet paper sheet edge and extend laterally outwardly to the wet paper sheet edge, where a second stepwise reduction begins that extends laterally outwardly beyond the shoe edge. Laterally outwardly of the second reduction, a stepwise increase in hardness extends to the belt edge. Alternatively, each edge portion may be of a single hardness, less than the hardness of the middle portion, with each edge portion overlying one of the shoe side edges.

Title: Seamless circular knit brassiere and method of making same
Inventor: OSBORNE HAROLD G
IPC: A41C3/00
Filed: 1998-03-24
Abstract: A seamless brassiere, and methods and blank for making the brassiere are described. In particular, a tubular blank is circularly knit, and first and second walewise extending longitudinal openings are formed along opposite sides of the blank, to form torso and neck openings for the brassiere. The blank ends are trimmed, if desired, to form the desired contour for the arm openings, then banding is applied to each of the torso, neck and arm openings, to thereby form a finished brassiere. At least the banding secured to the torso opening is elastic, in order that the garment may be secured closely about a wearer. In the finished seamless brassiere, the courses extend vertically, while the knit wales extend horizontally when the brassiere is worn, which provides an enhanced level of support for the wearer's breasts.
Patent CA-2234685-A1 (CA)
Inventor: ALVAREZ VERNON LEON
IPC: G01N33/68
Filed: 1996-11-11
Abstract: A method of identifying a peptide which permits or facilitates the transport of an active agent through a human or animal tissue. A predetermined amount of phage from a random phage library or a preselected phage library is administered in vivo or in situ to a site in an animal, such as into the gastro-intestinal tract. At a predetermined time, the phage which is transported across a tissue barrier is harvested at a harvesting site which is separated from the site of administration by the tissue barrier to selet transported phage. This transported phage is amplified in a host. This cycle of events is repeated (using the transported phage produced in the most recent cycle) a predetermined number of times to obtain a selected phage library containing phage which can be tranported from the site of administration to the harvesting site. The identity of at least one peptide coded by phage in the selected phage library is determined to identify a peptide which permits or facilitates the transport of an active agent through a human or animal tissue.

Title: Methods and apparatus for communicating data via a cellular mobile radiotelephone system
Inventor: ROACH PETER OWEN JR
IPC: H04L12/56
Filed: 1997-03-24
Abstract: A system for communicating data via a cel-lular network control channel of a cellular mobile radiotelephone system (CMR). A data message sys-tem for communicating data collected from remote data sources includes sets of reporting devices, at least one mobile switching center (MSC) of a CMR system, and a data collection system connected to said MSC via a first communications link. Each recording device monitors a remote data source to obtain selected data and thereafter transmits a data message containing the selected data. The MSC receives data messages via the cellular net-work control channel from reporting devices op-erating within coverage areas of the array of cells and forwards the data messages via the first com-munications link to the data collection system. In response, the data collection system stores the data messages and processes the selected data. A pag-ing acknowledgment system is also provided for communicating both (1) paging messages and (2) acknowledgment messages to confirm reception of the paging messages. The paging acknowledgment system includes at least one communications system, remote communications devices, and at least one MSC of a CMR system. In response to a paging message from a paging party, the communications system transmits data messages corresponding to the paging message via a communications link. The data message contains the type of data that is normally supplied with a conventional paging message and an acknowledgment code that uniquely identifies said data message. A remote communications device responds to a data message con-taining its particular address by transmitting an acknowledgment message containing the acknowledgment code to the MSC via a cellular network control channel of the CMR system. The MSC forwards the acknowledgment message to the communications system via a first communications link. The communications system confirms reception of the data message by comparing the acknowledgment code of the acknowledgment message to the acknowledgment codes associated with the paging messages.

Title: Short range/intermediate range laser defense against chemical and biological weapons
Inventor: LIVINGSTON PETER M
IPC: F41H13/00
Filed: 1998-12-09
Abstract: A intermediate range/short range laser defense system (10) for use against chemical and biological submunitions (36). The system includes a source (12) of a high power laser beam (14) which is directed by a beam steering device (16). The beam steering device (16) is controlled by a processor (20) which generates control signals (22) for orienting the beam steering device (16) to the control the laser beam (18). The processor (20) operates in a LACROSST mode which enables detection of the submunitions (36). The processor (20) receives tracking information from a detector (26) and tracker (24). The processor directs the laser beam ( 18) towards a centroid (40) of a dispersion pattern or cloud (38). The laser beam (18) is then directed in an outward, spiral path (42) from centroid (40). When the laser beam (18) encounters a submunition (36), the laser beam locks onto the submunition (36) in order to heat the submunition (36), thereby denaturing or destroying the submunition (36).
