Title: Method of thawing frozen road culverts
Inventor: SCHMIDT RUDIGER
IPC: E01F9/576
Filed: 1997-08-26
Abstract: A method for thawing frozen road culverts.   The first step involves positioning an electrically conductive cable in a  road  culvert  prior  to  an  ice  blockage  occurring.    A connection end of the electrically conductive cable is anchored in an accessible location.  The second step involves connecting a power source to the connection end of the electrically conductive cable after an ice blockage of the road culvert has occurred and supplying power to the electrically conductive cable, such that energy generated by power flowing through the electrically conductive cable causes a flow path to be created through the ice blockage in the road culvert.

Title: Improvements in a three-dimensional display system
Inventor: BLUNDELL BARRY GEORGE
IPC: H04N13/393
Filed: 1996-04-04
Abstract: The present invention relates to improvements in a three-dimensional display system. A transformation technique is described wherein deflection coordinates defining the spatial locations of the images written into the display volume are determined by transformation from a coordinate system based on the display volume to a coordinate system based on the one or more electron guns. The application further relates to technique by which the location of an electron beam within the display volume may be determined. These techniques involved positioning conductive material at various locations such as the screen and the enclosure of the display itself so that the impinging electron beam may be detected and thus the location of the beam in the display volume be derived.  Image enhancing techniques are described in conjunction with the location techniques whereby conductive films are evaporated onto the screen and/or the enclosure. Modifications in voxel plotting techniques are described so as to enhance the quality of the image produced in the display volume. The technique includes interlacing the scanned print location. An additional improvement is provided by a particular conduction medium configuration superimposed or deposited onto the screen where the conducting medium incorporates information which is extracted or read from the medium by scanning a particle beam across its face so as to invoke momentary voltages or currents in the conducting medium.

Title: An improved periodic wireless data broadcast
Inventor: WERTH JOHN ST CLAIR JR
IPC: H04B7/26
Filed: 1996-03-01
Abstract: An airdisk (80) performs a TDMA/FDMA (Time Division Multiple Access/Frequency Division Multiple Access) wireless broadcast, divided into periodically-repeated time-slotted data items, analogous to sectors on a rotating disk, over multiple broadcast frequencies, analogous to tracks on a disk. The data items (1-14) on the airdisk may be sorted according to user interest, user profile, or from polling user preferences as by the monitoring of an uplink for user requests. The monitoring of the uplink can be performed in a time less than the rotation period of the airdisk. Users may be precluded from requesting data already on the airdisk for a prescribed time period. The sorting of the data items may be according to rank of popularity, iteratively calculated by an objective function which exchanges ranked weighted data items on the airdisk to obtain the value of candidate sort orders which optimize the objective function.

Patent CA-2224894-A1 (CA)
Title: The h-y antigen
Inventor: ENGELHARD VICTOR H
IPC: C12N5/0783
Filed: 1996-07-29
Abstract: H-Y is a transplantation antigen that can lead to rejection of HLA-matched male organ and bone marrow grafts by female recipients, and may play a role in pregnancy and spermatogenesis. However, the origin and function of H-Y  antigens has eluded researchers for 40 years. We show that one human H-Y  peptide antigen presented by HLA-B7 is an 11 residue peptide derived from SMCY, an evolutionarily conserved Y chromosomal protein. A homologous gene on the X chromosome, SMCX, differs by two residues in the same region. We also show a peptide antigen recognized by two HLA-A2.1 restricted T cell clones, which is also encoded by SMCY. The identification of H-Y offers prospects for improvements in transplantation outcome, prenatal diagnosis and fertilization strategies.

Abstract: This device enables the transport of a pre-assembled lift system (32) to a building without this system having to be broken down.  Due to the construction of this transport and assembly frame (1) the entire lift system (32) can be already pre-assembled at the factory. Further, the length of the transport and assembly frame (1) allows transport in a standard container, so that it can be transported to any desired location in simplest mode and manner by rail, ship or truck and the entire lift system (32) is optimally protected against damage with a minimum of packing effort. Through the equipping of the transport and assembly frame (1) with rollers (15) the displacing on the construction site is facilitated. When the rollers (15) are driven in, support elements (20) of rubber, which are arranged at a basic support (4), fix the frame to the ground. The transport and assembly frame (1) can be folded up for return transport or storage, so that several transport and assembly frames (1) can be placed one on the other in space-saving manner.

Patent CA-2237712-A1 (CA)
Inventor: DIAZ MONICA SIGNORET
IPC: B29C59/02
Filed: 1996-11-15
Abstract: The creped nonwoven laminate loop material (10) of the present invention includes a creped nonwoven layer (12) attached to a support layer (14). The creped nonwoven layer (12) may be, for example, a spunbond nonwoven web or a staple fiber bonded carded web. The support layer (14) may be formed of any material that can be suitably attached or bonded to the creped nonwoven layer, including a foam, a plastic film or another nonwoven web. The exposed, top surface of the creped nonwoven layer includes raised "loop" areas (16) having low fiber density and high z-directional fiber orientation that are designed to receive and engage the hook elements projecting from a hook material. The raised areas (16) of the creped nonwoven layer are separated by non-raised areas having relatively higher fiber density and relatively lower zdirectional fiber orientation when compared to the fiber density and zdirectional fiber orientation of the raised areas. The primary areas of bonding or attachment of the bottom surface of the nonwoven layer to the top surface of the underlying support layer are the non-raised areas (20); in addition, some secondary bonding of the nonwoven layer to the support layer outside of the non-raised area may exist. The support layer (14) provides structural integrity for the creped nonwoven laminate material and dimensionally stabilizes the creped nonwoven layer. The creped structure of the nonwoven layer further provides resistance against compression of the fibers forming the hook receiving loop material during use, thereby facilitating entry and engagement of hook elements projecting from the hook material. The creped nonwoven loop laminate (10) of this invention can be employed as the loop material of a hook and loop fastening system, such as used on disposable personal care absorbent articles.
