Title: Sliding device for a fifth wheel
Inventor: ALGUERA GALLEGO JOSE MANUEL
IPC: B62D53/00
Filed: 2000-08-25
Abstract: The invention relates to a sliding device for a fifth wheel. The aim of the invention is to reduce the overall weight of the system consisting of vehicle frame/slide system and also to simplify its assembly. To this end, the base frame (10) is provided with two longitudinally extending angular profiles (11, 12) that are linked with each other by means of two detachable and slidably mounted tie-bars (15). Every angular profile (11, 12) comprises retaining means that interact with second retaining means of the upper part (30) in such a manner that the upper part (30) can be displaced relative to the base frame (10) in the longitudinal and the transversal direction. The inventive device does not require an auxiliary frame that is conventionally used.

Title: Acid catalyzed copolymerization of water and epoxy resin and uses thereof
Inventor: DICKENSON JOHN BARTRAM
IPC: C09D171/00
Filed: 2002-05-21
Abstract: Non-gelled polymeric polyols are prepared by the acid catalyzed copolymerization of epoxy resins and water. When the starting resin is an epoxy resin derived from bisphenol-A, the resulting product has much lower levels of bisphenol-A and diglycidyl ether of bisphenol-A (DGEBA) compared to traditional epoxy resins of comparable molecular weight prepared by the advancement process. The product can be cured with OH reactive crosslinkers such as amino resins and polyisocyanates to yield thermosetting coatings with useful properties.

Abstract: A fiber optic cable that includes an armor layer having inner and outer surfaces and defining a passageway therethrough, a protective jacket surrounding the armor layer, a plurality of optical fibers extending lengthwise through the passageway, and a water swellable element for inhibiting water migration through the passageway. The water swellable element can be a water swellable layer on at least one of the inner and outer surfaces of the armor layer and/or a water swellable yarn extending through the passageway. The fiber optic cable is preferably tubeless, i.e., free of buffer tubes. In instances in which a water swellable layer is on the inner surface of the armor layer, the optical fibers are capable of contacting the water swellable layer. Alternatively, in instances in which the fiber optic cable includes water swellable yarns but not a water swellable layer on the inner surface of the armor layer, the optical fibers are capable of contacting the armor layer and, more particularly, the plastic coating of the armor layer.  The fiber optic cable can exhibit shape retention whereby the fiber optic cable can retain a bent shape.

Title: Electronic game method and apparatus with hierarchy of simulated wheels
Inventor: CROWDER ROBERT W JR
IPC: A63F13/45
Filed: 1997-03-19
Abstract: A computer implemented electronic game includes a wheel of fortune game with odds of a jackpot greatly in excess of the number of indicia on a simulated wheel. In one embodiment, a virtual mapping allows a bonus indicium of the wheel to be given a l :M chance of being landed on, even though the bonus position is one of N positions on the simulated wheel. A random number L is chosen between l and M and this number is mapped to a number between l and N. The display of the wheel if controlled to simulate stopping of the wheel at the Ith indicium where L is mapped to I. In one embodiment, by using successive wheel spins, the odds of moving to the next round are multiplied to achieve an overall odds of winning a jackpot. In one embodiment there is a 1:50 chance of entering a bonus screen from a main slot machine/phrase completion screen, a 1:20 chance of landing on a bonus position in a first wheel spin, a 1:40 chance of landing on a bonus position for a second wheel spin and a 1:200 chance of landing on a bonus position for a last wheel spin to provide an overall odds of a jackpot of 1:8 million.

IPC: F04B43/02
Filed: 2001-03-12
Abstract: A liquid chemical metering pump (24) is described that can be fully submerge d within a hazardous liquid chemical transport/storage container (28). The pum p (24) includes a discharge adaptor (30) that can be received in the outlet aperture (40) of the container (28), in which it is held in sealing relationship by a suitable screw-threaded connector. The discharge adaptor (30) is provided with an intake port (32) in fluid communication with the liquid chemical in the container (28), and a discharge port (34) which is in  fluid communication with a discharge tube (36) leading to a flow stream (38) . The chemical metering pump (24) is remotely controlled by an electronic controller (26) connected by cable (25) to the chemical metering pump. The chemical metering pump (24) substantially eliminates the need for "double handling" of hazardous liquid chemical, as the chemical can be metered directly from the transport/storage containers in which it is delivered to t he end user. The pump (24) can be readily modified to suit different sized containers.

Patent CA-2405051-A1 (CA)
Inventor: CHUN DOSUNG
IPC: H01L23/50
Filed: 2001-03-30
Abstract: A natural-resource-conservative, environmentlaly-friendly, cost-effective, leadless semiconductor packaging apparatus (1000), having superior mechanica l and electrical properties, and having an optional windowed housing which uniquely seals and provides a mechanism for viewing the internally packaged integrated semiconductor circuits (chips/die) (40). A uniquely stamped and/or bent lead-frame (30, 41) is packaged by a polymeric material (12) during a unique compression-modling process using a mold, specially contoured to avoi d the common "over-packaging" problem in related art techniques. The specially  contoured mold facilitates delineation of the internal portions from the external portions of the lead-frame, as the external portions are the effective solderable areas that contact pads on a printed circuit board, thereby avoiding a laborious environmentally-unfriendly masking step and de- flashing step, streamlining the device packaging process. The compression-mo ld effectively provides a compressive sealing orifice from which the effective solderable areas of the lead-frame may extend and be exposed and, thus, avoi d being coated with the polymer which is uniquely contained by the mold for packaging the internal portions of the lead-frame. The lead-frame is uniquel y stamped and/or bent, conforming it to electro-mechanical requirements of a particular semiconductor product. By uniquely stamping and/or bending, the related art "half-etching" of the lead for conforming it to electro-mechanic al requirements of the packaged semiconductor product is no longer required. Environmental enhancement is achieved by conserving natural resources and by  eliminating hazardous material by products otherwise liberated in related ar t packaging techniques.
