Patent CA-2052811-A1 (CA)
Inventor: MASUDA KAZUAKI
IPC: H04J3/06
Filed: 1991-10-04
Abstract: In order to detect a plurality of framing bit sequences for establishing synchronization at a receiver in a digital communications system, first and second counters are rapidly reset in order to establish the synchronization as early as possible.  A comparator receives a bit stream transmitted and a desired bit sequence for use in detecting the framing bit, and compares the desired bit sequence with part of the bit stream and issues a coincidence signal in the event that the desired bit sequence coincides with the part of the bit stream.  The first counter is coupled to receive the coincidence signal, and allows an output indicating the establishment of the synchronization to issue in the event that it reaches a predetermined number of correct coincidence signals.  The second counter counts up the number of occurrences of the output of a clock counter, and resets itself and the first counter when reaching a predetermine number of occurrences of a pseudo-coincidence signal.

Title: Use of glycidyl phosphonates as crosslinkers in the preparation of hydrogels
Inventor: ENGELHARDT FRITZ
IPC: C08K5/5373
Filed: 1991-10-17
Abstract: Abstract The present invention relates to the use of com-pounds of the general formula I     I    in which R denotes alkyl, alkenyl or aryl, which can be optional-ly substituted, as crosslinkers in the preparation of hydrogels.       As the compounds of formula I are soluble both in water and organic solvents, the hydrogels so prepared have high gel strength in addition to high absorption capacity.  They are useful as absorbents for aqueous fluids, for the formulation of cosmetic preparations, as strengtheners and/or binders of fibrous surface structure containing reactive groups and as drilling muds and cement slurries in oil production.

Title: Onset of antiestrogen resistance in breast cancer
Inventor: OSBORNE C KENT
IPC: G01N33/94
Filed: 1991-09-04
Abstract: The present invention involves a method for early detection of developing tamoxifen resistance in breast cancer. Tamoxifen is the drug of choice for hormonal therapy of a first recurrence of breast cancer, but its use is associated eventually with emergence of resistant tumors. Whereas initial treatment is usually followed by tumor regression, resistant tumors may actually resume growth under continued tamoxifen treatment. Because such growth may actually be augmented by the tamoxifen, it is essential to identify the onset of resistance as early as possible so alternative therapy may be promptly instituted. Monitoring increased levels of estrogenic tamoxifen isomers or estrogenic tamoxifen metabolites signals developing resistance.

Abstract: ABSTRACT                  CONFIGURATION CONTROL UNIT FOR PROGRAMMING A FIELD PROGRAMMABLE GATE ARRAY          AND READING ARRAY STATUS                           F. Erich Goetting The present invention is used in an FPGA device having programmable logic cells and a programmable interconnect array. In a preferred embodiment in which the logic cells are programmed using transistors controlled by memory cells and the interconnect structure is programmed using antifuses, a configuration control unit (CCU) of the present invention can accomplish three functions: 1) applying programming voltages to terminals of the interconnect antifuses;  2) configuring the logic cells; and 3) reading status of signals on the interconnect structure.  The CCUs are connected together into a shift register.  Each CCU connects to a horizontal or vertical interconnect line.  At intersections of these interconnect lines are antifuses.  By loading logical 1's into the two CCUs, it is possible to address the antifuse at the intersection of the two interconnect lines. A voltage difference can then be directed to the two terminals of that antifuse for programming the antifuse.  After antifuses are programmed, configuration information is shifted into the CCUs to configure the logic cells.  These same CCUs can be used to capture the logical states of each of the interconnect lines, each CCU capturing one signal present on an interconnect line to which that CCU connects.  The captured data can then be shifted out through the shift register.

IPC: B29B17/02
Filed: 1993-05-21
Abstract: ABSTRACT   1.  Process for the production of a recycled plastic product made of varnished plastic parts and thermoplastical plastic recycling material.   2.1 Known processes pulverize varnished plastic parts in a multistage pulverizing process with approx. 300 to 500 µm.  The varnish particles contained in the fine ground material highly disturb the characteristics of the recycled plastic product.  For the removal the fine ground material is filtered respectively sieved out of the melt with immense efforts.  The new process shall eliminate this relatively uneconomical method and at the same time facilitate the creation of a thermoplastical plastic recycling material made of varnished plastic parts, which with its characteristics comes close to a reclaimed product.   2.2 According to the process solution varnished plastic parts are multistagely ground but not pulverized, while they at the same time are made subject to a stretching treatment during the pulverizing step to loosen a remarkable part of the varnish sticking thereto. Resulting plastic- and varnish particles are separated using a vibrating screen for example, and thereafter packaged, for example in the form of a granulate.  The thermoplastic plastic recycling material does not comprise any visible inclusions of more than 0,25 mm2 of varnished particles in the sheet test.   2.3 Recycling process for varnished thermoplastical shaped parts in general, specifically though related to the automotive industry and in particular the recycling of varnished bumpers.
