Abstract: A polymeric blend particularly useful as a VI improver, which polymeric blend comprises a selectively hydrogenated asymmetric radial polymer comprising a plurality of polymeric arms containing hydrogenated conjugated diolefin monomer units and at least one block copolymer arm comprising a single polymeric block containing predominantly monoalkenyl aromatic hydrocarbon monomer units and a single polymeric block containing predominantly hydrogenated conjugated diolefin monomer units and a selectively hydrogenated linear diblock copolymer containing a single polymeric block containing principally monoalkenyl aromatic hydrocarbon monomer units and a single polymeric block containing predominantly hydrogenated conjugated diolefin monomer units. Both polymers in the blend will be selectively hydrogenated so as to convert (saturate) at least 95% of the ethylenic unsaturation initially contained therein. When used as a VI improver, the polymeric blend unexpectedly improves the thickening efficiency over and above the thickening efficiency that would be expected from a consideration of the individual   contribution made by each of the polymers separately. The monoalkenyl aromatic hydrocarbon polymer blocks in both polymers is preferably styrene and the conjugated diolefin in both polymers is preferably isoprene. Preferably, both polymers are selectively hydrogenated so as to convert (saturate) at least 99% of the ethylenic unsaturation initially contained therein.

Abstract: A method of distinguishing between strips for different assays in an automated instrument, wherein characteristics to which the instrument is sensitive are selectively introduced in microwells of individual microstrips which are pretreated with a specific antigen or antibody for a particular test. On each microstrip, the wells having the characteristic collectively define a multi-bit code which corresponds to a particular condition or analyte to be tested for. The automated instrument reads the characteristic from the selected wells and thus determines what test is to be conducted. the marks may have optical, radioac­tive luminescent, fluorescent, or magnetic charac­teristics, in accordance with the test to be con­ducted.

Abstract: An inverter which performs switching operation that corresponds to a single frequency in response to drive signals (V GS1  to V GS4 ). An inductance element (L) is connected between output terminals so that it may provide parallel resonance with the total equivalent capacitance, which is the sum of the equivalent capacitance of the inverter (Q 1  to Q 4 ) viewed from the terminals and the equivalent capacitance of a load (LO). This makes it possible to decrease charge-discharge losses of capacitances (C OSS1  to C OSS4 ) in the source and drain.

Abstract: 1. Driving device for at least two pairs of wheels. 2.1 Driving devices (14) for all-wheel drives on motor vehicles (10), particularly on agricultural tractors, commonly suffer from the disadvantage that, when cornering, distortion occurs throughout the drive train or balancing of the wheel speeds is permitted by means of differentials, freewheeling mechanisms or similar devices, which leads, however, to a loss of traction as soon as one of the wheels comes in contact with a non-adhering surface. 2.2 It is therefore proposed to incorporate a traction drive (34) in the drive train between the pairs of wheels (16, 20) involved which adjusts either the mean speed of the pair of wheels (16, 20) or the speed of the two wheels (22) within a pair of wheels (20) to the turning radii covered. The traction drive (34) is adjusted by means of a programmable regulating device (36). 2.3 A driving device of this type has applications particularly on agricultural tractors, construction or forestry machinery. <IMAGE>

Abstract: The invention relates to the linkage of the running gear 2 and 3 and the frame 1 of a railway vehicle with wheel sets clamped securely via axle bearings in a running gear frame 4 and 5, the frame 1 being linked to the running gear frame 4 and 5 via leaf carrying springs 6 and open link suspension 7 without a bogie pin and a frictional rotation restrictor 8 being arranged between the running gear frames 4 and 5 and frame 1. The object of the invention consists in designing the link between the running gear 2 and 3 and frame 1 in such a way that, even when the axle is partially or completely relieved of load or the axle suspension loads, the leaf carrying springs 6 of the running gear 2 and 3 and thus the suspension of the open links 7 are stressed to such an extent that a sufficient restoring effect and a sufficiently large rotational restriction of the running gear 2 and 3 are maintained. This object is achieved in that, between running gear frames 4 and 5 and frame 1, a spring 10 is arranged which clamps said frames to one another and is acted upon inversely proportional to the stress of the leaf carrying springs 6 of the running gear 2 and 3. <IMAGE>

Abstract: A fluid flow sensitive valve mechanism (114) is positioned in a valve chamber (118) between first and second inlet-outlet ports (112, 122) and controls the opening and closing of a third inlet-outlet port (116) in response to the flow of fluid to and from the valve chamber (118) through two or more of the ports. The valve mechanism (114) includes a valve member (126) and a valve positioning device (146). The impingement of fluid flow acts on various surfaces of the valve mechanism so that (a) when fluid flows from the first port into the valve chamber the valve mechanism is moved to close the third port and to keep the third port closed so long as there is thereafter no fluid flowing from the second or third port into the valve chamber, and (b) when fluid flows through the first port (112) from the valve chamber (118), whether from the second port (122) or the third port (116) or both, the valve mechanism (114) is moved to open the third port. The valve mechanism is shown as being embodied in a master cylinder, in a generic push-pull hydraulic cable arrangement, and in a vehicle parking brake system where the valve mechanism is in a hydraulic substitute for the Bowden wire type of parking brake cable.

Abstract: The present invention relates to a microcontroller based adapter card that interfaces a Microchannel bus architecture to allow a personal computer implementing such hardware architecture to tune on a TV channel and capture digital data transmitted intermixed with an analog video signal used for diffusion of television programs. The receivers of such transmission system receive the incoming data stream, transmitted via "on air" or "cable" channels, through a TV cable of a broadcasting network or from the aerial antenna. Received serial data is decoded and stored into byte format for processing which is partially done by the on-board processor and then by the personal computer processor. This processing will result in storing data as records, messages and files formats into the personal computer mass storage devices. The on-board intelligence allows selectivity of transmitted data by checking the incoming addressing bytes (transmitted in the same data packet) against the card unique address or group membership parameter stored in non-forgeable devices.
