Title: Method for in vitro analysis of metal-induced allergies
Inventor: STEJSKAL VERA
IPC: G01N33/50
Filed: 1991-10-15
Abstract: ABSTRACT OF THE DISCLOSURE      The invention describes a procedure for the in vitro determination of allergy in vitro with the help of lymphocytes, so-called memory cells, in the blood, in which a lymphocyte fraction is isolated from defibrinated blood and is cultivated in the presence of an antigen with the aim of determination of eventual presence of memory cells for that particular antigen among the lymphocytes in which stimulated memory cells, so-called lymphoblasts, are determined by radioactive precursor incorporation into DNA and by morphological evaluation, which is characterized by the lymphocyte fraction which is repeatedly depleted of monocytes and other adherent cells.  The antigen may be metals, organic and inorganic compounds, ceramics, glass ionomers, pigments and composite materials.  The invention covers also the use of procedure for study of diseases which may be caused by metal allergy or in which metal allergy acts as promotor (contributing factor).

Title: Power supply circuit with power factor correction
Inventor: NERONE LOUIS R
IPC: H02M7/06
Filed: 1993-07-22
Abstract: POWER SUPPLY CIRCUIT WITH POWER FACTOR CORRECTION    ABSTRACT OF THE DISCLOSURE A power supply circuit for powering a load with bi-directional current comprises means for supplying d.c. power from an a.c. voltage, a series half-bridge converter, and a boost converter. The series half-bridge convener alternately impresses a d.c. bus voltage from a bus conductor across a load circuit first with one polarity and then with the opposite polarity. The series half-bridge converter includes a first switch interposed between the bus conductor and a bridge-switch end of the load circuit; a second switch interposed between ground and the bridge-switch end of the load circuit; and a switching control circuit for alternately switching on the first and second switches. The boost converter comprises a boost capacitor connected between the bus conductor and ground and whose level of charge determines the bus voltage on the bus conductor; a boost inductor for storing energy from the means for supplying d.c. power, the boost inductor being connected by a one-way valve to the boost capacitor for discharging its energy into the boost capacitor; and means for periodically connecting a load end of the boost inductor through a low impedance path to ground, such path including a boost switch. A condensed power supply circuit results from making the second switch of the series half-bridge converter additionally serve as the boost switch. An alternative circuit simplification results from making constant the ratio of on time to switching repetition period of the boost switch.

Patent CA-2115939-A1 (CA)
Inventor: ATKINS ROBERT M
IPC: C03C25/12
Filed: 1994-02-18
Abstract: Described is a new method and apparatus for measuring the thickness of a thin conductive coating deposited on a moving elongated dielectric body. Of special use is an application of a carbon coating on an optical fiber. The conductive coating is measured by establishing an electromagnetic field in a resonator including an elongated unshielded helix and a pair of coupling loops. The helix is suspended between the coupling loops out of contact with either one of them. An electromagnetic energy is coupled into one loop as an input signal from a source of electromagnetic energy and coupled out from the other loop as an output signal. The difference between the magnitude of energy of an empty helix or with an uncoated body, and the helix with a coated body, is used for controlling the coating process. The inner diameter of the helix is large relative to the diameter of the elongated body being at least five times the diameter of the fiber and the spacing between the coils of the helix being equal to the cross-sectional dimension of the rod, wire or tubing making up the coil. The general principles stated herein can be applied over a wide range of radio frequencies, typically from about 100 MHz to 100 GHz, and can be applied to a wide range of coating configurations by appropriately selecting a frequency range and equipment that is compatible with the selected frequency range.
Patent CA-2120052-A1 (CA)
Inventor: BECKER MANFRED
IPC: A01B63/10
Filed: 1994-03-28
Abstract: A hydraulic system includes a hydraulic pump, a reservoir, a hydraulic function, such as a cylinder, and a power beyond valve for controlling communication between the pump, the reservoir and the cylinder. The pump provides pressurized fluid at a pump output as a function of the pressure in a load sensing port. For generating a pump controlling load sensing signal in case that the cylinder does not generate such a signal, it is proposed to provide a valve which blocks in a first position or opens in a second position communication between the feed line of the cylinder and the load sensing port of the pump. The valve functions in dependence of control pressures acting on each side of a valve member. A spring is provided biased to urge the valve member to its first closed position. Further, shift valve means are provided to supply selectively different pressures to both sides of the valve member. In an open-center hydraulic system, the valve means the shift valve means connects the first side of the valve member to the reservoir and the second side of the valve member to the feed line. In a closed-center system, the shift valve means will be changed over to connect the first side of the valve member to the feed line and the second side of the valve member to the pump outlet.
