Title: Audio-visual aid for teaching musical notation - has conducting strips on display board to control musical note generator so instructor can draw notes and play melodies by touching them
Inventor: REITMAIER DIETER
IPC: G09B15/04
Filed: 1979-10-13
Abstract: Strips of metal, separated by small gaps, are laid horizontally across a blackboard and connected to the control inputs of a musical note generator. The strips are painted over with conducting paint, without bridging the gap, so that can still be used as a blackboard. Two sets of five lines are marked along the middle of alternate strips to represent music staves (7) and the treble and bass clefs are added. The music teacher can draw notes in chalk (38) on the staves. By touching a note with a metallic pointer (30), connected to the generator, he can sound the note. By holding an electrode in the hand, several notes can be touched with the fingers to play a chord. Each strip has three buttons associates with it, to select whether the note sounds at its natural pitch or a semitone higher or lower, so that a key signature can be written on the staves and the generator set to play in that key.

Patent DE-2947495-A1 (DE)
Inventor: BULA KARL
IPC: B60C27/12
Filed: 1979-11-24
Abstract: The clamping means of the anti-slip device includes a pair of locking members for selectively clamping the overlapping wire ends of the wire in a manner so as to only permit movement in a sense of a shortening of the effective length of the wire. A pair of release members are actuated simultaneously by a frame so as to move the locking members from an inclined position in which the wires are clamped to an upright position in which the wires are free to move through the locking members. The clamping wire is secured within the helical spring forming the resilient pull element at a point diametrically opposite the clamping means. With the anti-slip device fitted onto a wheel and with the release members in a locking position, the locking members allow the clamping means to move relative to the wire ends only in the sense of a shortening of the effective length of the wire. With the release members and the locking members in the release position, the wire ends can move relative to the clamping means in the opposite direction. This anti-slip device can be readily fitted onto a wheel. Further, the device can be reliably secured in place with take-up being automatic.

Filed: 1981-02-27
Abstract: The disposable syringe is sealed by a disc (13) on the rear end of the barrel (10), the disc being integrally formed with the piston rod (12). On insertion of the piston (11) into the barrel (10) the disc (13) is trapped and retained by an engangement means (14, 15) on the rear end of the barrel (10). On further insertion of the piston rod (12) the disc (13) is torn off the piston rod (12) and forms a seal for the rear end of the barrel (10). This prevents contaminants from reaching the barrel wall. In comparison with syringes which are not sealed at the rear end, the production and assembly process does not necessitate any additional steps. <IMAGE>
Patent DE-3107949-A1 (DE)
Inventor: FRIEDEL RUDOLF DIPL PHYS
IPC: H01J35/16
Filed: 1981-03-02
Abstract: In an exemplary embodiment, a metallic shield for the discharge space between the cathode and the anode is connected to a potential which is greater than half the tube voltage and smaller than the entire tube voltage. What is achieved thereby is that backscatter electrons from the focal spot space are withdrawn and the anode load carrying capacity is thereby increased, and that the outside-of-focus component of the radiation is reduced as well. Moreover, a very close-to-focus definition or collimation of the cone of rays is possible. X-ray tubes according to the disclosure are particularly applicable in medical X-ray diagnostics.

Patent DE-3109620-A1 (DE)
Title: Worldwide travel-plug adapter
Inventor: HERBST MANFRED DR
IPC: H01R31/06
Filed: 1981-03-13
Abstract: The worldwide travel-plug adapter is an electrical engineering commodity. There are four different plug-socket systems in the world which are not mutually interchangeable because of their different shapes and sizes. These are: 1) the American system, 2) the Commonwealth system, 3) the South European system, and 4) the German system. If someone is travelling to America with their electric razor or charger for a dictaphone of German origin, then they need an adapter. In order to avoid having to carry a multiplicity of adapters when travelling through different countries, I have invented the worldwide travel adapter. This adapter contains all four plug systems stated. If, for example, the traveller is in America, then he just needs to move the contact pins designated America (6) into the in-use position in order to be able to plug the adapter into an American socket, while the other contact pins remain in the retracted position in the adapter. If he now travels to a Commonwealth country, then the American contact pins are moved into the retracted position and the Commonwealth pins into the in-use position. The apparatus plug side of the adapter can accommodate all the plug systems, so that this adapter can be used anywhere in the world. <IMAGE>

Patent DE-3114767-A1 (DE)
Title: Bicycle light system
IPC: B62J6/00
Filed: 1981-04-11
Abstract: The invention relates to a bicycle light system which preferably has at least two galvanic elements or cells which are connected in series and output an electrical voltage to at least one load or filament lamp, specifically in particular in accordance with Patent Application P 3106569.4. In the case of such a bicycle light system, the filament lamps can relatively easily burn through as a result of unacceptable overloads so that the illumination required for safety in traffic is no longer possible. So that the operating range for the filament lamps can also be restricted and light is thus radiated over the longest possible period with a comparatively high degree of brightness, it is proposed to assign a limiting device to the load or the filament lamp by means of which device voltage and/or current peaks are kept away from the load or the filament lamp or at least however reduced. <IMAGE>
