Title: Methods and compositions for preventing and treating chronological aging in human skin
Inventor: KANG SEWON
IPC: A61K31/19
Filed: 1998-02-23
Abstract: The deleterious effects of the passage of time on human skin (i.e., chronological aging of human skin) can be prevented and treated with the topical application of a retinoid, preferably retinol. We have found that some of the same pathways (namely the stress-activated pathways, SAPs) activated in photoaging of human skin (i.e., sun-induced premature skin aging) are similarly elevated in the skin of elderly people. We have also found that other pathways (namely the mitogen-activated ERK pathway) is depressed in the same skin. Treatment of chronologically-aged skin with a retinoid both inhibits degradation of dermal collagen and promotes procollagen synthesis. Biopsied sections from skin of elderly (80+ years old) show that a single treatment can increase epidermal thickness, improve the dermal collagen density, and promote the formation of rete pegs and dermal papillae (see Fig.  13), and can decrease the amount of c-Jun and increase the amounts of Types I and III procollagen (see Fig. 18). Such benefits are also helpful in preventing bruising, tearing, and ulceration of elderly skin.

Title: Method and apparatus for generating a complex scrambling code sequence
Inventor: RAMESH NALLEPILLI S
IPC: H04J13/10
Filed: 1999-09-29
Abstract: A complex spreading and/or scrambling code sequence ("scrambling code sequence") generation system uses a first complex code sequence having at least two components and a second complex code sequence having at least two components. The components of the first complex code sequence are respectively mixed with the corresponding components of the second complex code sequence to generate the complex scrambling code sequence. In doing so, an offset between the components of the complex scrambling code sequence is achieved for the same and/or different users. For example, the complex spreading code sequence generation system can use a long code generator which produces a long code sequence produced from the inner product of a code vector and a user mask. The long code sequence is provided to an I path and a Q path. To produce a complex long code sequence, the long code sequence on the Q path is delayed to produce a second long code sequence on the Q path or a Q component of the complex long code sequence. On the I path, the I  long code sequence or the I component of the complex long code sequence is multiplied with an I component of a short code sequence to produce the I component of the complex scrambling code sequence. On the Q path, the Q long code sequence is multiplied with a Q component of the short code sequence to produce the Q component of the complex scrambling code sequence. As such, the offset between the components of the complex scrambling code sequence between different and/or the same user is at least the period of the short code. The complex scrambling code sequence can be used for spreading, scrambling, de-spreading or de-scrambling an information signal.

Title: A method of rolling superconducting conductor lengths and roller apparatus
Inventor: HAN ZHENGHE
IPC: B21C37/04
Filed: 1998-07-14
Abstract: A roller apparatus and a method of rolling in particular superconductors, wherein a roller apparatus is used that comprises two roller bodies arranged opposite each other whereby the roller bodies form opposed roller surface planes; and wherein means are arranged for driving the two roller elements about their axes of symmetry in such a manner that the element to be rolled is pulled in between the roller surface planes by the friction generated between the element to be rolled and the roller surface planes. In accordance with the invention, the roller apparatus is so configured that the roller bodies comprise at least two annular or tubular roller bodies; and wherein the annular or tubular roller bodies are further provided with surfaces that form an annular track; and in that the roller apparatus has a pressure device which is arranged for abutment on the annular track in such a manner that the roller surface planes are pressed towards each other; and wherein the pressure device is configured and located in such a manner that the pressure device is in abutment on only a fraction of the annular track on the annular or tubular rollers. Hereby it is possible to roll with very large roller diameters without ensuing significant risk of the rollers being undesirably deformed during the roller process. In particular for the rolling of superconductors, experiments have shown that improved properties are obtained for the rolled superconductor.
Patent CA-2298804-A1 (CA)
Title: Two-part manual test connector
Inventor: HART JAMES E
IPC: B60T17/04
Filed: 2000-02-16
Abstract: A test connector enables measurement of pressures contained within a body. The body houses check valves and includes studs to attach a cover to a head of the body. Removal of the cover renders the check valves accessible. The check valves are normally compressed against valve seats formed in the head but when moved away from their seats provide access to the pressures. The test connector includes a contact plate, a support plate, two springs sandwiched therebetween and two double flanged nuts. Each spring is disposed so that it is axially aligned with throughholes defined in the plates. Each nut has its middle section disposed coaxially within one of the springs and its flanged ends keep the plates in proximity to each other while the springs seek to force them apart.      Hollow plungers have one end seated in plunger bores in the support plate with the other end free to slide through flow bores in the contact plate. As the nuts are initially threaded onto the studs, the contact plate soon seals against the head without the plungers emerging from the flow bores. As the nuts are further threaded onto the studs, the support plate moves toward the contact plate thereby further compressing the springs and eventually forcing the plungers to emerge from the flow bores to unseat the check valves.      This permits each of the pressures contained thereby to communicate through the hollow plungers and out the plunger bores thereby allowing access to the pressures within the body.

Title: Method for the preparation of complex dna methylation fingerprints
Inventor: OLEK ALEXANDER
IPC: C12Q1/6886
Filed: 1998-11-27
Abstract: The invention relates to a method for characterising, classifying and distinguishing tissues and cell types, for predicting the behaviour of tissues and groups of cells, and for identifying genes which have altered in their expression. Said method is characterised in that the base cytosine (not 5-methyl-cytosine) in a genomic DNA taken from any tissue sample is converted into uracil through treatment with a bisulphite solution. Fractions of the genomic DNA which has been treated are amplified by using very short or degenerated oligonucleotides, and the remaining cytosines of the amplified fractions are detected by means of hybridisation or polymerase reaction. The data generated from the analysis and automatically transferred to a processing algorithm is then used to draw conclusions as to the phenotype of the cell material which was analysed.
