Filed: 1999-05-24
Abstract: A method and apparatus pump a laser gain medium of a laser rod having a first longidunal axis. At least one pump light source (42) emits pump light to the laser rod (12), and the pump light source has a second longitudinal axis (46) which is perpendicular to the first longitudinal axis (14). Radiation from various laser diode arrays is collimated and uniquely arranged in a vertical orientation in relation to the laser gain medium.  Reflectors (38) focus the collimated radiation from the diode arrays onto the laser gain medium to achieve fundamental mode operation or Transverse Electromagnetic mode (TEM00 mode) operation. Both laser gain medium and reflectors may be simultaneously cooled with appropriate fluids in the apparatus. The assembly of the apparatus may be extended to hold a plurality of vertically oriented laser diode arrays to increase the laser pump power.

Abstract: A screen cylinder, and a method of making the screen cylinder, take into account the stress concentrations that are formed, particularly at the inner  and outer surfaces of the finished screen cylinder, so as to minimize them. The stress relief minimization is accomplished by providing a plurality of stress relief grooves (25) in land areas (121) between accept flow providing  grooves (113) that are in substantially end-to-end alignement, the stress relief grooves each having a depth between about 10-80 % (e.g. between about  40-60 %) of the thickness dimension (119) of the plate (110), so as to reduc e by at least 10 % (e.g. about 30-50 %) the magnitude of deformation of the screen slots (115) due to compression or tension in the surfaces of the scre en cylinder as a result of cylinder formation from the plate, compared to if th e relief grooves were not present.

Title: Use of cladribine on a stent to prevent restenosis
Inventor: FALOTICO ROBERT
IPC: A61K31/7076
Filed: 2001-02-22
Abstract: The current invention comprises an approach to solving the clinical problem of restenosis, which involves the administration of the antiproliferative antineoplastic agent, cladribine, to patients undergoing PTCA or stent implantation. In one embodiment of the invention, cladribine is administered to patients systemically, either subcutaneously or intravenously. In another embodiment of the invention, cladribine is bound to the surface of a stent by means of incorporation within either a biodegradable or biostable polymeric coating. Alternatively, cladribine could be incorporated into a stent constructed with a grooved reservoir.

Title: Method and system for providing personal base station communications
Inventor: KRISHNAMURTHI RAJEEV
IPC: H04B7/26
Filed: 1999-07-27
Abstract: A portable phone (236) may operate inexpensively as a cordless phone when in a micro-cell generated by a micro-base station (202), or flexibly as a cellular phone when it leaves the micro-cell and is served in a macro-cell generated by macro-base station (204) operating on the same frequency. When a mobile phone (222), served by the macro-base station (2042), drives by, the signals from the micro-base station (202) (intended for the portable phone 236) drown out the signals from the macro-base station (204). This invention solves the problem by having the micro-base station (202) receive, delay, and retransmit (on a 50 % duty cycle - half the time receiving and hall retransmitting) all signals transmitted by macro-base station (204), in addition to transmitting its own signal. The delay appears to the mobile station (222) as a resolvable multi-path delay, and it continues to be able to receive the signal intended for it.

Inventor: LYNE ROBERT CHAMBERLAYNE JR
IPC: B25B27/22
Filed: 2001-06-18
Abstract: A drive-on system for installing a tire chain (i.e., snow chain) on a pneumatic tire mounted on a vehicle wheel. The system includes a U-shaped installation tool whose arms releasably engage fastening elements (hooks or links) at one end of each side chain, and a installation tray or ramp in which the connected tire chain and tool are arranged, and may be stored, prior to installation, with the tire chain in a partially laid-out orientation and the tool preferably within a tool compartment in the tray. To install the tire chain, the vehicle is driven onto the tray and stopped, preferably in a predetermined optimum position in response to a signal initiated by a position-indicating switch on the tray. Then the tool, with one end of the tire chain connected to it and trailing it, is drawn upward and circumferentially around the tire. With the tool bridging the tread of the tire so that its arms extend along the opposite sidewalls, the tire chain is draped and tensioned substantially in the correct position on the tire. The fastening element at the other, free end of each side chain is then removed from its place in the tray and connected to the mating fastening element. The connection on the inner sidewall is preferably made while the tool is still connected, which enables the arm of the tool on the inner sidewall to be used to guide the free element into contact and connection with the element connected to the tool.

Title: Safe freeze
Inventor: HUMBER MICHAEL
IPC: F25C1/24
Filed: 2001-09-19
Abstract: The product I would like to patent is a fitted lid atop the standard ice-cube tray. The lid may be permanently attached or detachable. An attached lid prevents the consumer from misplacing the lid, and also prevents the frustrations of assembling the two pieces every time. The closing mechanism would be a folding piece rather than screws or hinges. Thin will prevent the lid from freezing shut. The fastening mechanism should be as simple as one to several raised pieces on the inside closing flap. This will allow for a quick snap to open and close the lid. A fitted lid serves two main purposes: to protect against unwanted foreign particles that may be found as detrimental to the health of consumers, and ; to better accommodate stacking one ice-cube tray on top of another.
