Title: Device for measuring a level of material using microwaves
Inventor: OTTO JOHANNGEORG
IPC: G01F23/284
Filed: 1993-12-08
Granted: 1998-06-16
Abstract: A level measuring device using microwaves comprises an antenna for sending transmitted waves toward the surface of a material whose level is to be measured, and for the reception of echo waves resulting from reflection at the surface, and a receiving and evaluating circuit which derives from the echo waves received by the antenna an echo function representative of the echo amplitudes as a function of the distance and determines from the echo function the transit time of the microwaves from the antenna to the surface of the material and therefrom the distance of the surface of the material from the antenna. In order to detect the formation of deposits of the material on the antenna or further trouble conditions, such as damage to the antenna or the loss thereof, the level measuring device comprises an arrangement which compares a section of the echo function originating from a reference reflection point in the antenna or in the vicinity of the antenna with a predetermined threshold value and produces a signal indicating the existence of a state above or below the said threshold value. The reference reflection point may be constituted by a part of the antenna or a separate reference reflector mounted in the antenna or in the vicinity thereof

Title: Bimodal portable telephone
Inventor: BURSON KYLE LESLIE
IPC: H04W88/06
Filed: 1994-11-07
Granted: 1999-02-16
Abstract: A bimodal portable telephone provides cellular service and improved cordless service in a common handset. Operation of the bimodal portable telephone in a cellular telephone system provides telephone service over a wide geographical area of coverage through operation with multiple cellular bases and in a cordless telephone system provides telephone service over a localized geographical area of coverage through operation with an associated cordless base. The cordless service provides improved performance over convention cordless telephone service by advantageously employing a frequency hopping spread spectrum modulation technique for communications between the portable telephone and the cordless base unit. This improved performance achieves increased operating range of the cordless telephone system. This increased operating range is particular advantageous to the user of the portable telephone in that it permits this more economical system to be used over a much greater distance than is possible with convention cordless telephone service. Also commonality of circuitry within the portable telephone is facilitied through the selection of operating frequencies for the cordless telephone system to be in close proximity with those of the cellular telephone system.

Abstract: Four novel Bacillus thuringiensis strains, which are deposited at the BCCM-LMG  under accession nos. LMG P-12592, LMG P-12593, LMG P-12594, and LMG P-13493, produce new crystal proteins during sporulation that are toxic to Lepidoptera, more particularly against Noctuidae such as Spodoptera spp. and Agrotis ipsilon, against Pyralidae such as Ostrinia nubilalis, and against Yponomeutidae such as Plutella xylostella, and that are encoded by a novel gene. The crystal proteins contain pro-toxins, which can yield a toxin as trypsin-digestion product. A plant, the genome of which is transformed with a DNA sequence that comes from either one of the strains and that encodes its respective toxin, is resistant to Lepidoptera. Each strain, itself, or its crystals, crystal proteins, protoxin or toxin can be used as the active ingredient in an insecticidal composition for combatting Lep-idoptera.

Abstract: A liquid crystal display device (30) that is illuminatable by diffuse ambient light comprises a liquid crystal panel (32) and a reflective holographic optical element (34). Diffuse ambient light illuminating the front side (36) of the liquid crystal panel and traversing the liquid crystal panel is received at a reflection site (66) and is redirected with a reflection pattern (68) to retraverse the liquid crystal panel to form a bright pixel for a display. By concentrating diffuse light within a preferential reflection pattern, the reflective holographic optical element provides enhanced brightness for viewing the display under ambient light conditions. In one aspect, the reflective holographic optical element is a transflector (158, 208) and is combined with an internal light source (170, 220) for illuminating the display using either reflected ambient light or backlighting.

Title: Co-adhesive system for bonding wood, fibers, or agriculture based composite materials
Inventor: SLEETER RONALD T
IPC: C08L97/02
Filed: 1995-10-11
Granted: 2005-08-09
Abstract: The invention provides an adhesive system comprising a blend of resin and a co-adhesive conjugated triglyceride, which is especially well suited to bonding composite panels such as oriented strand board, particle board, plywood, MDF, hardboard, and similar panels. The resin is a fast acting bonding material which forms a mat of fibers into a self sustaining panel within a time limit during which a press may be economically utilized. The triglyceride acts slower so that, after the panel is formed, there is enough time to penetrate the fibers to a depth that results in a superior bonding.
