Patent CA-2020506-A1 (CA)
Title: Apparatus for engaging and disengaging a permanent-magnet slipper brake
Inventor: MUELLER WALTER
IPC: B61H7/08
Filed: 1990-07-05
Abstract: INVENTORS:  WALTER MULLER and MAX KOLLER           INVENTION:  APPARATUS FOR ENGAGING AND DISENGAGING A             PERMANENT-MAGNET SLIPPER BRAKE                ABSTRACT OF THE DISCLOSURE            For engaging and disengaging a permanent-magnet slipper brake for a rail vehicle there are required relatively high forces which are generated either by a hydraulic motor or an electric motor.  Therefore, in rail vehicles without electric or hydraulic connections and comprising solely a pneumatic brake line or brake-pressure lead, there is incorporated a pneumatically driven hydraulic power pump by means of which a hydraulic motor can be driven. This hydraulic motor is then capable of applying the forces required for engaging and disengaging the permanent-magnet slipper brake.  The engaging and disengaging process is preferably controlled by a main air line.

Title: Nucleic acid detection method using unequal primer concentrations in polymerase chain reaction
Inventor: WU ANNIE L
IPC: C12Q1/68
Filed: 1990-09-10
Abstract: NUCLEIC ACID DETECTION METHOD USING UNEQUAL PRIMER CONCENTRATIONS IN POLYMERASE CHAIN REACTION             Abstract of the Disclosure The detection of nucleic acids can be achieved with certain advantages in polymerase chain reactions by using primers in unequal concentra-tions. In particular, the molar ratio of a pair of primers is at least 2:1.  Amplification of the nucleic acid of interest is carried out using standard reagents, but denaturation of the comple-mentary products prior to detection is not needed. Detection is then accomplished using an enzyme-labeled reagent which will provide a colorimetric or fluorometric signal in the presence of the appro-priate substrate.
