Patent DE-4207156-A1 (DE)
Title: Electrical switch and fuse-holder construction with two external electrical connections - has on=off switch with one movable and one fixed contact, two second connections in series between first movable switch contact working directly with fuse connection
Inventor: BOEK SICCO
IPC: H02B1/18
Filed: 1992-03-06
Abstract: The switch incorporates two spring loaded (2) parallel strips (3) clamped as a pair with the connecting blade (4) of a melting fuse (5). The strips on both sides of the fuse are parts of a fuse holder, and are located with their free ends in U-shaped profiles (6), and can move against the hinge axis line (7) via the to and from movement of a switch strip (8). The construction uses the connecting blade (4) as fixed contact of a switch, the movable contact of which is formed by the strips (3). The other free end of the switch strip (8) works in conjunction with a fixed contact (10). This contact is connected with external connections of the construction (1) so that the fuse (5) is completely insulated from the connections carrying voltage. ADVANTAGE - Contact force may be as low as 5 kg. Allows simple installation and removal of fuse.

Patent DE-4209518-A1 (DE)
Title: Superconducting magnet system and holder - generates strong magnetic field when electric current flows through superconductive, magnetic coil
Inventor: FUKUMOTO HIDESHI
IPC: F17C13/00
Filed: 1992-03-24
Abstract: The superconducting magnet spool construction is activated or excited very quickly. The generation of heat in a magnet spool holder (2) by an eddy current is reduced and quenching is surpassed. The eddy curent is induced from a dynamic current e.g. vibration or magnetic field oscillatin. The holder is of low specific resistance material. A part (11) with high specific resistance is provided at at least one section of the holder circumference. This part is at a place where vibration is small. When the spool is acitvated the eddy currents in the circumferential direction are reduced at the high resistance part (11). When the dynamic current is produced the generation of heat by the eddy current from the low resistance material (10) is supressed. USE/ADVANTAGE - Prevents transfer from superconducting to a normal conducting state i.e. quenching, and supresses generation of heat from eddy currents without affecting rise time needed to reach given value of operating current.

The indent ball locates in a 'V' groove in the base unit (3). The ball is held in the groove by the action of a coil spring (16) located within a cylindrical sleeve (6,7). The sleeve moves vertically during disengagement and is supported on linear ball bearings (15). The line of force action (19) is at an angle to the main centre line. USE/ADVANTAGE - Avoids clamping of latch element. Low cost, simple to produce use with gearboxes.
Patent DE-4222877-A1 (DE)
Inventor: ZUMKELLER MARKUS
IPC: H04H20/67
Filed: 1992-07-11
Abstract: In the course of increasing improvement of the transmission quality in broadcast media, the introduction of digitisation is also intended for sound radio. For this reason, a digital transmission method called "Digital Audio Broadcasting" (DAB) has been developed. In this method, the programmes offered are transmitted, for example, in common-frequency mode throughout the country. In order to be able to distinguish between certain transmitters or regions, however, it is known to let different transmitters transmit different identifications on additional single-carrier frequencies which are regionally different. The novel method makes it possible to transmit information which is regionally different in addition to the current sound radio programme. This does not require any additional transmission bandwidth. In the receiver, this information, if necessary supplemented by other information stored in the receiver, can be indicated to the user or used inside the device. As a result, traffic radio announcements, for example, can be transmitted to the user as required, or a message can be output stating in which geographic region the user is currently located. The novel method can be used in digital audio broadcasting. <IMAGE>

Title: Lidded drum
Inventor: BURGDORF MAERTEN DR
IPC: B65D43/02
Filed: 1993-06-29
Abstract: The invention relates to a lidded drum, having a thin-walled lining which is inserted in the drum body and can be clamped between the drum opening edge and the drum lid. In the case of customary linings, however, air can penetrate between the outer wall of the lining and the inner wall of the drum body; in particular cases, this can be undesirable or disadvantageous. In order likewise to seal off the gap between the outer surface of the lining and the inner surface of the drum wall in a gas-tight and fluid-tight manner, it is proposed that the lining be sealed off relative to the lidded drum body in the upper or upper outer region of the drum opening edge by means of a further peripheral seal.
