Title: Apparatus for displaying a selected picture as desired
Inventor: LANTING ULBE JAN
IPC: G09F11/02
Filed: 1994-05-20
Abstract: The invention relates to an advertising board comprising generally three-sided prisms which by their edges abut one another and do so again after a rotation by 120 degree. In order to counteract friction and jolting (jerking), the drive member has an engaging section 7 which causes the driven member 4 to rotate slightly about its shaft 3, thus causing a driver part 8 to move into the path of a follower part 9, which leads to virtually no sliding of these parts with respect to one another and consequently results in smooth action. Suitable drive means for the invention include a self-excited (permanent-magnet) electric a.c. motor. <IMAGE>

Title: Container for compressed gas for firing a projectile
Inventor: WIJDEVEN GIJSBERTUS GERARDUS P
IPC: F42B6/10
Filed: 1994-08-24
Abstract: The present invention relates to a container for compressed gas, designed for firing a projectile. This measure results in such a simple construction that the fabrication costs are minimal, specifically so minimal that the costs per firing of the projectile are considerably lower than those for the prior art container. Moreover, dispensing with a container suitable for a large number of firings keeps the mass of the firing apparatus low. The invention further relates to a firing apparatus suitable for firing a projectile by means of a container according to one of the preceding claims, comprising a chamber suitable for holding a carrier according to any one of claims 16-18, a pointed firing pin (fuse pin, striker, striking pin) which can move as far into the chamber as the position of the container to be fitted, and a duct connecting the locations of the container and the projectile in the chamber.
Patent NL-9401876-A (NL)
IPC: G05D1/02
Filed: 1994-11-10
Abstract: A feed wagon for feeding silage or concentrate, or both, to animals, such as cows, which comprises automatically operated loading and unloading mechanisms. The wagon selectively automatically loads silage at ground level at two slot silos and silage or concentrate at a standing silo. It discharges in a feed alley between stalls in a cowshed. The route between the slot silos, the standing silo, and the feed alley is marked by active or passive beacons. The wagon carries detectors for detecting the beacons and a computer which cooperates with the detectors and steering mechanisms for the wagon to move the wagon between the slot silos, the standing silo and the feed alley travelling on the route marked by the beacons. The method comprises automatically loading relatively small quantities of silage on the feed wagon, moving that silage to the feed alley by guidance from its onboard computer and detection of the passive beacons between the silos and the cowshed, automatically discharging the silage in the feed alley to be received by stalls, moving the feed wagon after discharging silage to a selected silo by guiding the onboard computer and detection of the beacons along the route and repeating these steps on a substantially continuous basis.

Title: Command processor and switching controller apparatus
IPC: G06F13/36
Filed: 1985-12-10
Abstract: A switch controller for a dynamic switch (10) responds to commands from a using system to provide control signals to the dynamic switch (10) which causes the switch to establish and breakdown paths between sources and destinations in the using system. The controller includes a plurality of command registers which are temporarily assigned to a command source for receiving command signals, decoding said signals and providing control signals to the switch for establishing or breaking down a switch path. The controller may if desired provide an echo to a selected destination so that proper execution of commands may be ascertained. After the commands are completed the control register is released for reassignment to another command source while an established switch path remains intact. Thus, commands may be received from any source for controlling the switch.
