Title: Electronic mouth organ with rotary valves - which control volume, and has deflecting strips coupled to strain gauges giving digital signals fed to continuous electronic programme
Inventor: MOELDERS FRANZ ING GRAD
IPC: G10D7/12
Filed: 1979-02-22
Abstract: The mouth-organ has a rotry valve in each screen controlling the volume and shutting off a tone chambeR, the valve having an elongated hole working with openings in the housing. The invidiaul cells n195) in the mout-piece have deflecting material strips (196) moved in opposite directions by inhalation and exhalation and coupled to strain gauges on both sides, so that with the different length alterations on deflection a diferential voltage is generated, used for analogue control of volume. When the strip is in the rest position and slightly deflected from it a digital signal is produced, and the direction of voltage drop shows the deflection direction. The digital signals are fed to a continuous electronic programme operating the control valve solenoids. For diatonic plyaing setting is by a single button, there being a separate button for each basic tone cutting in the appropriate programme. For mono-accord playing, one button is used for the base tone and a second for the tone gender, two part-programmes being electronically combined into a complete one. A control valve is only opened and shut under the effect of two independent simultaneous movements generated by solenoids.

Title: Reusable and hermetically sealable plastics container and cover - comprises polystyrene body and acrylic! cover glued together with EVA hot-melt adhesive
Inventor: CHEN ALEX CHUEN-FENG
IPC: B29C51/14
Filed: 1979-11-02
Abstract: Reusable plastics container with lid (which is also of plastics and reusable) is hermetically sealed by means of thermoplastics hot-melt adhesive. This is achieved by coating the rim of the container with adhesive and glueing the lid on. The adhesive is such that it has a greater affinity to the plastics of which the lid is made than to the material of the container, after the adhesive has set. As a result, when the container is opened and the lid lifted then the adhesive will peel off the container and be thus removed together with the re-usable lid. The container is pref. made of impact-resistant polystyrene, the material for the lid is pref. an acrylic copolymer and the hot-melt adhesive is an ethylene vinyl acetate copolymer.

Title: voltage selector circuit for e.g. LCD(s) - uses MOS transistor and eliminates power loss caused by difference between voltage of output signal and substrate voltage
Inventor: TAMAKI NOBUO
IPC: G04G9/00
Filed: 1979-12-20
Abstract: In the voltage selector circuit, a number of supply voltages (V0, V1, V2) are respectively supplied to a number of switching elements formed of MOS transistors (11, 12, 13, 14, 15). The transistors are turned on and off according to the voltage levels of input signals (A0, A1) supplied, to provide a selected one of the supply voltages at output terminal (B0). The substrate electrode of one transistor (15) is selectively connected to supply voltages (V1, V2) via further switching transistors (17, 18) which are also controlled by input signal. The drain/substrate diode is never forward biassed, thus reducing power loss in the circuit. The circuit is used for e.g. driving liq.-crystal display devices for electronic desk top calculator, watches, clocks, or ink jet printer.

Their separating distance is in a fixed proportion to the wavelength of the Knock vibrations.
Patent DE-3034377-A1 (DE)
Inventor: WOHLRAB WALTER
IPC: F04B49/08
Filed: 1980-09-12
Abstract: A three-way or three-ported flow-regulating valve for use in a hydraulic system comprises a two-position two-ported throttle valve inserted between an inflow conduit and an outflow conduit and a pressure-relief valve connected to the inflow conduit at an upstream point thereof and at a downstream point proximate to an intake port of the throttle valve. A servovalve is connected in parallel to the throttle valve via small-diameter pressure-transmission channels extending to the intake port and to an output port of the throttle valve. Upon a jump in the pressurization of the inflow conduit, for example due to the activation of an auxiliary pump, the pressure-relief valve opens; it closes again only upon an equalization of the pressure throughout the inflow conduit. The servovalve has a biasing spring which exerts a force determining the maximum pressure drop across the throttle valve.
