Title: Method of producing a factor viii (ahf) containing fraction
Inventor: SCHWARZ OTTO
IPC: A61P7/04
Filed: 1987-10-19
Granted: 1992-03-10
Abstract: ABSTRACT OF THE DISCLOSURE:     There  is  disclosed  a method of producing a Factor VIII          (AHF) containing fraction having a specific activity of at least 2.5 units of Factor VIII/mg protein as well as a portion of immunoglobulin G (IgG)  of 10 mg/1000 units of Factor VIII at the most. Its risk of transmission of viral or  bacterial  infections  is  to  be  avoided  or  largely reduced. The method consists in that undesired proteins are at first precipitated from a Factor VIII (AHF) containing plasma fraction in the presence of SPS. The purified Factor VIII containing solution is treated with suitable salts or salt mixtures in order to obtain a Factor VIII containing precipitate. This precipitate is dissolved, lyophilized and finally heat-treated.

Title: Movement monitor
Inventor: TAO BILLY S K
IPC: A61B5/113
Filed: 1988-04-06
Granted: 1991-12-03
Abstract: A B S T R A C T     This invention relates to a movement monitor that is suitable for detecting movement, and also provides an alarm should movement that is being monitored cease. The movement monitor is particularly suitable for use with humans or other living organisms where breathing movement is being monitored.          In considering the use of the movement monitor on human infants, it is particularly useful for preventing death from Sudden Infant Death Syndrome. The movement monitor comprises a rigid base member for supporting the moving object which is being monitored, and is provided with a reaction means which is secured to the base member and arranged to extend over and be held in contact with the moving object. A transducer is placed between the rigid base member and the moving object such that when movement occurs, the reaction means causes force to be applied to the transducer. The use of the reaction means provides a more positive application of movement force to the transducer thereby providing a greater deal of reliability in detecting movement. The output from the transducer is connected to a circuit means which is arranged to provide an alarm should the output from the transducer sense no movement from the moving object.

Title: Method for measuring hemoglobin
Inventor: LEVINE ROBERT A
IPC: G01N33/72
Filed: 1988-08-17
Granted: 1993-06-22
Abstract: ABSTRACT OF THE DISCLOSURE            A whole blood sample is placed in a tube such as a capillary tube, with a plastic float.  The float is axially elongated and has a specific gravity which causes it to float in the packed red blood cells when the sample is centrifuged in the tube. The hemoglobin concentration of the packed red blood cells is measured by measuring the depth that the float sinks into the red cell layer, and then the hemoglobin concentration of the blood is calculated.  The hemoglobin can be measured in this manner because virtually the only red cell component which contributes density to the red cells is the hemoglobin.  The hemoglobin concentration of the whole blood is calculated by multiplying the mean corpuscular hemoglobin concentration of the packed red blood cells by the packed cell volume % (hematocrit) of the whole blood.  All of the necessary calculations may be performed by a preprogrammed microprocessor.

Abstract: ABSTRACT OF INVENTION      A multi-stage catalytic process for hydrogenation and liquefaction of coal using ebullated-bed catalytic reactors to produce low-boiling hydrocarbon liquid products, in which used catalyst is removed from a lower temperature first stage reactor operating at a temperature not exceeding about 800°F and cascaded forward to a higher temperature second stage reactor for further use therein.  Reaction conditions in the first  stage  reactor  are preferably 700-800°F temperature, 1000-4000 psig hydrogen partial pressure,  and a coal feed rate of 10-90 lb coal/hr per ft3 catalyst settled volume in the  reactor.   Useful  higher  temperature  or  second  stage reaction conditions are 750-850°F temperature, and 1000-4000 psig hydrogen partial pressure.  The used catalyst withdrawn from the  lower  temperature or  first  stage  reactor has  a catalyst age of 300-3000 lb coal proced/lb fresh catalyst, and is transferred forward to the higher temperature second stage reactor for further use to catalyst age of 1000-6000 lb coal processed per lb freash catalyst.  If desired, a higher temperature third catalytic reactor can be provided and used catalyst from the second stage reactor cascaded forward into the third reactor for fur her u e wherein.  Useful catalysts include metal oxides of cobalt,  iron,  molybdenum,  nickel, tin, or tungsten deposited on a base of alumina, magnesia, silica,  or titania,  with cobalt moly  and nickel moly on alumina   catalyst   being   preferred.       This   process advantageously required a smaller quantity of fresh catalyst per  ton  of  coal  processed  to  produce  the  low-boiling hydrocarbon liquid products.

Abstract: A noise reduction circuit comprises a high pass filter for extracting a signal component containing noise from an input signal, a variable level limiter for limiting the level of the signal component extracted by the filter to produce a noise suppressing signal, and a level adjustor for adjusting the level of the noise suppressing signal.  A level detector detects the level of the input signal, and a control signal generator generates first and second control signals based on the detected output of the level detector, supplies the first control signal to the level limiter so as to control the limit level thereof, and supplies the second control signal to the level adjustor so as to control the gain thereof.  In a signal subtracter, the noise suppressing signal from the level adjustor is added with reversed polarity to the input signal to suppress the noise contained in the input signal and thereby produce a low-noise output signal.

Granted: 1991-09-24
Abstract: Abstract of the Disclosure:     In a satellite communication system for carrying out communication between a central station and local stations, each local station includes a receiving apparatus (41) which comprises a converting unit (43) for converting a received radio signal of a received carrier frequency into a converted signal by using a reception carrier signal of a reception carrier frequency and a demodulating unit (44) for demodulating the converted signal into a demodulated signal.          Connected to the demodulating unit, a deciding unit (45) decides whether the demodulated signal is normal or abnormal.  The deciding unit produces an abnormal signal when the demodulated signal is abnormal.  After reception of the abnormal signal, a timer circuit (47) measures a lapsed time to produce a time up signal when the lapsed time is equal to an integral multiple of a predetermined time interval.  Responsive to the time up signal, a supplying section (49) alternately supplies first and second carrier signals indicative of first and second memorized frequency signal preliminarily memorized in a memorizing section (48), respectively, one at a time as the reception carrier signal to the converting unit.
