Patent FI-92881-C (FI)
Inventor: EKINS ROGER PHILIP
IPC: G01N33/543
Filed: 1989-02-03
Granted: 1995-01-10
Abstract: Methods for measuring the concentration of an analyte in a sample are provided. The sample is contacted with a receptor molecule having binding sites for the analyte which is labeled with a first marker under conditions whereby only a small fraction of the binding sites on the receptor become occupied by the analyte. The receptor having fractionally occupied binding sites is then back-titrated via a back titration technique which includes a second marker different from the first, and the relative strengths of the two signals produced by the markers are measured thereby providing a value representative of the fractional occupancy of the binding sites on the receptor molecule by the analyte. This value is compared with one or more corresponding values obtained in the same way using one or more standard liquid samples of known analyte concentration.

Date Jul. 11, 1991.For picking up and moving containers with corner castings on platforms, railway wagons or ships, two carriages are locked one to each end face of the container. These carriages have sets of wheels, which are vertically movable therein and allow displacement of the carriages in their longitudinal direction. With the wheels of each set at the same height, the carriages are in the lowest position and can be locked by locks in the corner castings of the container. By moving one wheel of each set of each carriage down, the carriage and, if locked thereto, the container are lifted for displacement. Such wheels can bridge gaps between loading surfaces and differences in height between such surfaces. The carriages may also have wheels with a horizontal axis transverse to the other wheels, to allow movement of the carriages with or without a container transversely to their longitudinal direction.

Abstract: Method of coding and decoding messages wherein a basic key and a random message key, which is transmitted prior to the message, are used. Using a plurality of basic keys entails the problem that the proper basic key must be set in the receiving station. In accordance with the present method, the sequence of a portion (II) of the message key and of a number of check characters derived therefrom are coded, prior to the actual message transmission, using the basic key and a different portion (I) of the message key. Decoding in the receiving station is done by using a basic key which is chosen from a group of basic keys, and the different portion (I) of the message key. A test circuit 21 examines whether the decoded check characters correspond to the check characters derived in the receiving station from the decoded portion (II) of the message key. A positive test result indicates that the desired basic key has been found.

Title: Overload current protection apparatus
Inventor: WALTZ RICHARD W
IPC: H02H7/085
Filed: 1991-08-29
Granted: 1995-10-10
Abstract: A device protects an electric load, such as a motor, from excessive current levels.  The current flows from a source to the load through a switch and a primary winding of a current sensing transformer.  The voltage across a secondary winding of the current sensing transformer is rectified to produce a voltage which is measured to determine the level of current through the load.  The voltage across the secondary winding also powers components of the device.  In a first mode of operation, current from the secondary winding is applied to charge a power supply capacitor.  In a second mode of operation the level of the rectified voltage is sensed to produce a sample of the level of the current flowing through the load.  From this sample the change in temperature of the load since a previous sample is calculated and used to derive the present load temperature.  When the present load temperature exceeds a defined threshold level, the switch is opened to disconnect the load from the electricity source.
