Title: Closed belt conveyor for underground mining operations
Inventor: WILHELM PAURAT FRIEDRICH
IPC: B65G15/08
Filed: 1982-01-28
Granted: 1983-05-19
Abstract: Closed belt conveyor for underground mining operations, in particular, a roadway conveyor. The basic construction includes a tension means, a conveying belt with roller trucks alternately arranged on the longitudinal edges of the conveying belt, and a continuous guide rail. The tension means is attached at least to the roller trucks of one longitudinal edge of the conveying belt. The roller trucks are lined up in the continuous guide rail on the one side in at least one transport section, are guided with a hanging conveying belt closed in a tube shape, and open on the other side in at least one feed section and at least one emptying section which are each equipped with an additional arresting guide rail. The guideway unit has in the transport section merely the continuous guide rail in which the roller trucks of both longitudinal edges of the conveying belt are guided. The arresting guide rails are attached as a switch to the continuous guide rail via a fork piece at the same level. Located in the entry-side or in the exit-side fork piece is a switch element for the roller trucks which alternately diverts the incoming roller trucks into the allocated arresting guide rail of the feed section or the emptying section. The roller trucks are guided with the same running roller or running rollers in both the arresting guide rails and the continuous guide rail. <IMAGE>

Title: Arrangement for identifying objects equipped with interrogation devices
IPC: G01S13/74
Filed: 1982-06-29
Granted: 1986-07-17
Abstract: In this arrangement, the resistance to interference is intended to be improved and the probability of detection by an enemy and self-interference are intended to be reduced, consideration of the reliability of identification having precedence. To achieve this aim, selective interrogations of responders are carried out at predetermined times or in predetermined spatial and angular areas, the transponder of the responder being constructed with an antenna having a rotating directional pattern at the receiving end. The directional antennas of interrogation device and responder are matched to one another in such a manner that only one interrogation direction is allowed at a predetermined time. <IMAGE>

Title: Device for magnetically inputting detonation information into a projectile
Inventor: SIEBERT RAINER
IPC: F42C17/04
Filed: 1984-11-29
Granted: 1995-03-02
Abstract: A device for magnetically inputting detonation information into a projectile (11) which can be fired from a weapon barrel (13) is intended to be designed for the purpose of being able to set a detonation delay circuit (34) on the basis of the actual muzzle velocity (vo) from the muzzle of the weapon barrel (12) without any design changes or equipment supplements being required for this purpose in or on the conventional weapon barrel (13). To this end, magnetic sensors (16) having coils (20) and permanent magnets (21) assigned to them are arranged close to the projectile wall (17) and offset with respect to one another in the direction of the projectile longitudinal axis (14), but such that they are not covered by ferromagnetic parts, by means of which magnetic sensors (16) the attenuation of the magnetic field (22), which passes through the coils and is closed via the ferromagnetic material of the weapon barrel (13) when in each case one magnetic sensor (16) emerges from the muzzle of the weapon barrel (12), is detected and is converted into successive exit signals (24) for a speed measurement circuit (25). This results in the detonation delay time of the projectile (11) being matched exactly to its ballistic trajectory data on the basis of the actual firing speed or muzzle velocity (vo) of the respective projectile (11). <IMAGE>

Patent DE-3833936-C1 (DE)
IPC: G01N33/68
Filed: 1988-10-05
Granted: 1989-09-21
Abstract: A method is known for the determination of osteocalcin in human serum or plasma, in which a sample of the biological fluid containing the osteocalcin to be determined is incubated, together with a defined amount of an oligopeptide tracer, with a suitable anitbody which binds both the osteocalcin and the tracer. This method has proved to be susceptible to error in that the incubation conditions affected the measured levels, and the osteocalcin levels obtained were often too high. The recognition that the observed errors are attributable to a proteolytic breakdown of the oligopeptide tracer by constituents of the serum or plasma resulted in the technical teaching of the addition of one or more proteolysis inhibitors to the sample of human serum or plasma before or together with the addition of the oligopeptide tracer, specifically either a mixture of an endopeptidase inhibitor with an aminopeptidase inhibitor or, when an N-terminally protected oligopeptide tracer is used, only an endopeptidase inhibitor. Preferred inhibitors are amastatin and leupeptin.

Title: Mobile crane ballast system - uses clamps, actuator cylinders and locking systems to move ballast plates from swung-out position to transit position
Inventor: WILLIM HANS-DIETER
IPC: B66C23/74
Filed: 1989-04-19
Granted: 1990-08-16
Abstract: The mobile crane ballast plate is fitted to a platform between the outer axles on the bottom carriage and has hydraulic cylinders in the cantilevered part of the top carriage so that the piston rods can lock into registered holes in the ballast plate in the swung-out position so as to clamp the ballast plate to an abutment plate on the top carriage when the piston rods retract.  The platform (13) should have two twist bolts (18) to lock the ballast plate(s) (11,12) and each piston rod (21) is power-rotated to move its own adjuster (34) between lock and release settings. Each piston rod as it homes into its plate hole couples to the respective twist bolt so as to unlock this when the rod adjuster is in its locked setting and vice versa when the adjuster is in its release setting. USE/ADVNATAGE - Mechanical handling, cranes.  Ballast plates moved into transit setting in quick time without driver leaving cab.

Title: Reducing signal response non-uniformity reduction system for thermal imaging detector - using stored differences between reference output voltages from each detector element for reference radiation values
Inventor: KOEHLER LUDWIG DIPL ING
IPC: H04N5/33
Filed: 1993-02-20
Granted: 1994-05-05
Abstract: The non-uniformity reduction method for the signal responses provided by individual elements of an IR detector subjects each detector element in sequence to two reference input radiation values, the differences between the corresponding output voltages (U1, U2) being stored. During the scanning phase the actual output voltage of each detector element is compared with one of the reference output voltages and divided by the stored reference voltage value difference, or multiplied by the reciprocal of this difference. ADVANTAGE - Ensures high uniformity of IR detector element signals even when response appears within wide dynamic range.
