Title: Process for comparative screening of substances having a pharmacological activity
Inventor: CZERNILOFSKY ARMIN PETER
IPC: C12Q1/66
Filed: 1997-06-25
Abstract: The invention concerns a method of comparative high-throughput screening of pharmacologically active substances. In one process step the substances are deposited on test cells that contain one or more biological target molecules, the cells having an identical biological base composition and differing in their target molecules, and/or are deposited on cells having a different biological base composition and identical target molecules. The effect of the substance on the activity of the target molecules is measured using a detection system linked to the activation of the target molecule and is compared directly with the effect on other molecules.

Title: One-piece ceramic terminal insulator mounting arrangement
Inventor: ST LOUIS ROBERT MAURICE
IPC: H05B3/06
Filed: 1999-05-27
Abstract: There is disclosed a one-piece ceramic terminal suitable for use for mounting an electrical conductor in insulated relation to a supporting wall of a heating assembly. The ceramic insulator has a central block adapted to pass through a central portion of an aperture in the supporting wall.      This aperture has two radially extending slots extending outwardly of the central portion. The ceramic terminal includes a first pair of diametrically opposed radially extending wings which are sized to pass through the radially extending slots in the aperture. The ceramic insulator has a second pair of diametrically opposed radially extending wings which are sized larger than the slots in the aperture so as to engage one surface of the supporting wall. Once the first set of wings pass through the aperture and corresponding slots, the ceramic insulator is rotated such that the second set of wings engage the other surface of the supporting wall so as to mount the insulator relative to the supporting wall. An electrical conductor passes through a central slot in the ceramic insulator and is bent to prevent the insulator from rotating relative to the aperture in the supporting wall and prevent disengagement insulator from the supporting wall.

Title: High speed infrared/convection dryer
Inventor: TESAR MICHAEL G
IPC: F26B3/30
Filed: 1998-01-05
Abstract: A combination infrared/convection dryer or oven (10) for drying travelling webs (W). A shutter assembly (8) is provided between the infrared radiation source (16) and the moving web in order to selectively expose the web to infrared radiation. Drying efficiency is optimized by adding heated impinged air at high velocity on the machine direction ends and between the infrared elements. The air being discharged on the web is heated as it is pulled gross the elements to a centralized return air duct (42). The return air is pulled into the inlet of a close coupled supply fan (28) which then discharges the air to the nozzles. A portion of the air is also exhausted at atmosphere to maintain the oven enclosure in a negative pressure state, thus drawing fresh make-up air into the oven housing through the web inlet (12) and outlet (13) slots. Flotation nozzles (151, 152) can be used where contactless support of the running web is desired. Enhanced drying of the web and/or a coating on the web at high speed is achieved without a concomitant increase in dryer length.

Title: Dynamo-electric machines and control and operating system for the same
Inventor: BLUM DIETER W
IPC: H02K21/28
Filed: 1998-01-29
Abstract: A dynamo-electric machine which can function as a motor or a generator. The machine comprising a stator and an armature (80), and switching of the armature coils (c1-c7) is accomplished by means of a switching control assembly which is mounted to, and rotates with, the armature. In operation as a motor, direct current is supplied through brushes to slip rings (68, 70) that rotate with the armature, and the DC current supplied is first passed through switch means (92) in the control assembly to deliver the current in properly timed relationship with respect to the rotation of the rotor. This provides greater versatility in the operation of the motor/generator and eliminates many of the problems related to the use of conventional brush commutation commonly used in present day DC motors and generators.

IPC: B05B9/04
Filed: 1997-06-05
Abstract: The present invention provides a nozzle (10) for a pressurized container comprising a discharging tube (11), an actuator (12) and blocking means (20).  The discharging tube (11) is coupled to a valve of a pressurized container when the nozzle (10) is applied on a pressurized container. The valve in its open position allows the discharge of a product contained in the pressurized container through the discharging tube (11) when the actuator (12) is pressed.  The blocking means (20) prevent the opening of the valve when the discharging tube (12) is an undesired inclination. The blocking means (20) comprises a movable, non-compressible barrier (21) and a recess (22). The recess (22) is such that the recess (22) contains at least partially the barrier (21). The recess (22) further has a 360~ access symmetry for the barrier (21) so that the access of the barrier (21) into the recess (22) is obtained at a desired inclination of the discharging tube (11) independently of the orientation of the nozzle (10) when the nozzle is handled by a user. The blocking means (20) prevent any substantial movement of the actuator (12) when the actuator (12) is pressed, and consequently the opening of the valve when the nozzle (10) is applied on a pressurized container, when the barrier (21) is located at least partially outside the recess (22).
