Title: Improved process for the production of esters from natural fats
Inventor: STERN ROBERT
IPC: C11C3/04
Filed: 1993-09-24
Granted: 2008-03-18
Abstract: A description is given of an improved process for producing esters from natural fats (vegetable and animal fats) and from low molecular weight alcohols, in which the soaps and the oily compounds entrained in the alkaline phases are recycled by treating them, after acidification and separation, with a fraction of the glycerol phase produced, in the presence of an alkaline catalyst and in order to form at best a triglyceride or a partially substituted glyceride. This process makes it possible quantitatively to obtain methyl, ethyl, propyl or butyl esters which can be used as a substitute for gas oil.

Title: Method and apparatus for making a graphic product
Inventor: HEVENOR CHARLES M
IPC: B41J11/00
Filed: 1993-10-15
Granted: 2000-02-08
Abstract: A method and apparatus for preparing graphic products utilizes a printer to print on sheet material and a cutter to cut the sheet material with the printed material within the periphery of the cut edges. Both the printer and the cutter are controlled by machine readable data having a common data base so that the printed material and the cut material correspond positionally in the final graphic product. The printer is a thermal printer that places the printed material on a strip of sheet material generally before the sheet material is cut, The thermal printer utilizes a donor web bearing a transfer ink to create enhanced printed images on the sheet material with half tones, color and other attractive features. The printer is controlled to regulate a number of printing parameters through coding on a cassette in which the donor web is supported.

Title: Dual system cellular cordless radiotelephone apparatus with sub-data channel timing monitor
Inventor: SCHELLINGER MICHAEL J
IPC: H04W88/06
Filed: 1993-06-01
Granted: 1998-07-07
Abstract: A cellular cordless telephone may receive cellular telephone calls via a cellular telephone system and receive telephone calls on a system having a limited radio coverage area. To reduce the amount of time spent in monitoring the sub-data channel of the limited coverage area system, a timing signal is generated which represents the period of time spent monitoring the radio channel. During the monitoring, a predetermined number of data words transmitted on the limited radio coverage area radio channel system are received. When a first received data word is detected, an allowed monitoring time value is adjusted to be the sum of the value of the timing signal and the product of a determined number of received words to be detected and the time required for each word. This adjusted value of the monitoring time value is compared to the value of the timing signal and when the adjusted monitoring time value equals or exceeds the timing signal value, the monitoring of the radio channel ceases.

Title: Inducer for condensing furnace
Inventor: CHOU RUDY S
IPC: F24H3/06
Filed: 1994-06-03
Granted: 1998-08-18
Abstract: An inducer for causing a flow of combustion air into and gases of combustion through and out of a furnace of the condensing type.  The inducer is intended for use, without modification of its design or size, in a series of furnaces of  the  same basic design but having different  heating capacities and therefore different requirements for flow through the induction flow path.   The furnace design is such that a given furnace is capable of operation so as to provide a flow of air to be heated that is either up, down or  horizontal  with  only  minor  field  modification  on installation.  The inducer has two discharges, only one of which is used in a given installation.  The other discharge is blocked with a plug of special configuration that can vary the output of the inducer to ensure optimum flow of combustion air into and gases of combustion through and out of the furnace.  The inducer configuration is such that, in every possible orientation of the furnace installation, at least one of its two drains is at the low point of the inducer housing so that all condensate that collects in the housing can flow to a low point drain regardless of the orientation of the furnace.

Abstract: An electronic apparatus has a demodulating section and a strap antenna having a conductor in its inside. Radio waves received by the strap antenna are demodulated by the demodulating section. A receiving-sensitivity adjustment member having at least one through hole for passing the strap antenna in it is slidably placed on the strap antenna. Since a magnetic substance built in the receiving-sensitivity adjustment member changes the electric field generated in the conductor of the strap antenna, receiving sensitivity can be adjusted to the most appropriate state. With an insulator member placed on the strap antenna, a loop antenna can be used as a monopole antenna. When the strap antenna is made detachable, another antenna can be used depending on the use condition.

Abstract: A thermo-electric power generating element has the structure that two kinds of metal sheets or foils 10, 11 being in the relation of thermocouple combination are laminated together and connected at one end and the other end alternatively, so as to form a plurality of thermocouples connected in sereis. When hot junctions 12 are held at a high temperature, a temperature gap along the thermal flux is generated in the sheets or foils 10, 11. Electromotive force at every thermocouple derived from the temperature gap is summed up to a voltage level effective for outputting electric power through takeoff leads 13, 14. This power generator is useful for converting waste heat to electric power. When the thermocouple pile is made from corrugated sheets or foils, electric power is outputted with high efficiency.

Title: System and method for focused-based image segmentation for video signals
Inventor: CHEN TSUHAN
IPC: H03M7/30
Filed: 1996-04-11
Granted: 2000-04-04
Abstract: Motion video is represented by digital signals.  The digital signals can be compressed by coding to reduce bitrate and thus save time and expense in transmitting and reproducing the video.  The present invention is a system and method for reducing the amount of information required to satisfactorily reproduce video signals by distinguishing more pertinent portions of the video from less pertinent portions.  In particular, edges are detected based on amplitude variations in the luminance characteristic of the picture elements.  Sharp edges are deemed to be "focused".  The portion of the video frame between the focused edges is deemed to be focused, as well.  A template is created corresponding to the focused portion.  A signal corresponding to the outline of the template is combined with the original frame signal to create a segmented frame signal.  When motion detection information is available, a motion-based template may be created and intersected with the focus template.  A signal corresponding to the outline of the intersected template may be transmitted with the frame signal as the segmented frame signal.
