Title: Method for measurement of mercury vapour concentration
Inventor: SLAVOV LOZAN S
IPC: G01N27/416
Filed: 1990-07-13
Abstract: This method is used in analytical appliance engineering, for measuring the concentration of mercury steam in the atmosphere, in the chemical industry as well as for environmental control. It is simplified and is implemented easily. Description : a piece-resonance transducer is blown through with a voluntary volume of gaseous mixture for a certain period of time, because the process is based on the dependency of its own frequency of the resonator, from the additional mass accumulated on the electrodes of the resonator. The analysed mixture is pumped out into the atmosphere and the time interval is measured. In this way, the frequency of the resonator f1 is changed to a preliminarily-set value f2. The concentration is determined by the correlation of the frequency to the time interval according to the formula<IMAGE>where a is a constant, and Tx is the measured time interval.

Title: Isolation of fetal cells from maternal blood to enable prenatal diagnosis
Inventor: MUELLER UTZ W
IPC: C12N5/073
Filed: 1989-12-05
Abstract: ABSTRACT        This  invention relates to a method for the isolation of trophoblast (placental) sells from the blood of a pregnant mammal so as to provide the essential starting material, namely cells derived from the fetus, to enable genetic and/or biochemical information about the fetus to be obtained.  In particular, this invention relates to the use of monoclonal antibodies specific for membrane protein markers on mammalian trophoblasts to isolate trophoblast cells from maternal blood.  These cells may then be used to obtain fetal genetic and/or biochemical information early in pregnancy.  The present invention is particularly relevant for detecting human fetal abnormalities.

IPC: B22D11/06
Filed: 1990-06-27
Abstract: According to this method, molten metal is cast between two rolls (1, 2) with parallel axes, driven in rotation in opposite directions and whose walls are cooled. Use is made of at least one roll whose generatrix is curved and whose diameter is slightly smaller in its axially central part than towards its ends, and the metal is kept in contact with the wall of the said roll over an arc which is longer in the said central part than towards the said ends. To this end, the casting device comprises a riser (3) whose lower edge (33) of the longitudinal walls (31) is in contact with the walls of the said rolls at the top of the nip (5) between the latter, and the line (35, 35') of contact of the lower edge of the longitudinal wall of the riser with this roll is curved so that the length of the arc of the surface (6, 7) of this roll between the said line and the said nip is greater towards the middle of the said longitudinal wall than over its edges. <IMAGE>

Patent CA-2021515-A1 (CA)
IPC: C03C25/24
Filed: 1990-07-19
Abstract: Abstract A buffered optical fiber includes an optical fiber comprising a core and a cladding. Typically, the optical fiber is enclosed by at least one layer of coating material. The optical fiber is enclosed by a plastic buffer layer. Interposed between the optical fiber and the buffer layer is a decoupling material which provides a controlled coupling of the buffer layer to the underlying coating material. As a result, there is sufficient adhesion between the buffer layer and the underlying coating material to maintain the buffer layer in place during normal use of the buffered optical fiber. On the other hand, the adhesion is low enough so that the buffer layer may be removed upon the application of reasonably low stripping forces. Advantageously, the decoupling material also allows the selective removal of the optical fiber coating material as well as the plastic buffer layer.

Title: Cvt hydraulic start clutch
Inventor: LARSON CRAIG S
IPC: F16H9/12
Filed: 1990-08-07
Abstract: ABSTRACT OF THE INVENTION A hydraulically-actuated starting clutch  (10) for a continuously variable transmission which is designed to reduce the centrifugal  torque of  the clutch with respect to the chain belt/sheave torque. This is accomplished by adjusting the diameters of the  clutch  piston  (18)  to  reduce  the  resultant clutch  torque  to  a  value  lower  than  the  chain belt/sheave torque.   A pair of oil  feed passages (83,  84)  are positioned in the clutch assembly to feed oil through openings (82) in the friction plate (78)  at  all  times  during  operation,  even  when rotation of the friction plate ceases.   Further, an improved retractor spring  (64)  is utilized in the clutch   assembly   (10)   with   circumferentially extending  tabs  (68)  on  its  inner  periphery  (66) which extend over the snap ring  (62)  holding the spring onto the actuating piston  (18)  to prevent release of the snap ring due to centrifugal force during operation of the clutch.

Title: Emergency elevator power supply with component mode switching and frequency control
IPC: B66B1/00
Filed: 1990-08-15
Abstract: A simplified elevator power system using an AC-DC converter, both to convert AC to DC during normal operation and to convert stored DC power to AC during power failures. A power source monitoring relay monitors AC power coming from a utility, and upon power failure, switches a battery from a charging mode to a power source mode wherein DC power is supplied, not only to an inverter for driving a motor, but also to a converter hooked up to run as an inverter during such power failure in order to provide stepped-up AC voltage to elevator control devices.  In this way, the prior art addition of an extra inverter is avoided.
