Patent EP-0460390-A2 (EP)
Inventor: KUHN MAX
IPC: H01H3/30
Filed: 1991-04-25
Abstract: The spring energy accumulator drive (210) for the high-voltage switch (218) has a spiral spring (216) which can be tensioned by means of the tensioning device (212). The high-voltage switch (218) can be switched on once and off once using the energy stored in the tensioned spiral spring (216). The energy stored in the fluid-pressure accumulator (258) is sufficiently large to charge the spiral spring (216) at least once. The operating stroke movement of the piston rod (242) in the direction of the arrow (A) is converted via the toothed wheel segment (236) into a rotation of the toothed wheel (232), which engages therewith, through 360 DEG . In this way, the spiral spring (216) is tensioned via the tensioning lever (230). When the three-way valve (256) changes over, the cylinder-piston unit (214) is connected in terms of flow to the low-pressure reservoir (266), as a result of which the toothed wheel segment (236) is pivoted back under the force of the restoring spring (250), and the cylinder-piston unit (214) is moved back into the quiescent position. Relief of the tension on the spiral spring (216) is prevented by the return lock (232), and the coupling between the tensioning lever (230) and the toothed wheel (232) is neutralised by a free wheel. The cylinder-piston unit (214) can be driven using thin hydraulic oil, which allows reliable operation over a wide temperature range. <IMAGE>

Abstract: This invention relates to methods, apparatus and solutions for cryopreserving microscopic biological materials for biologically extended periods of time. The method comprises treating a suspension of biological material, in a appropriate buffer, with a cryoprotectant or combination of cryoprotectants which raises the glass transition temperature range of the sample. One or more dry protectants may be added to the cryosolution. The cryosolution is then nebulized and rapidly cooled with novel apparatus, dried by molecular distillation, stored and then rehydrated in a buffer prior to its use. The solutions comprise novel mixtures of cryoprotectants.

Abstract: The invention relates to a method for the heating of the admission air in combustion engines by means of a flame starting system which has at least one glow plug and is controlled such that, during a first time period, the glow plug is continuously preheated and, in a second following time period, is operated in a pulsed manner and that the glow plug is switched off after the expiry of a safety time. In order to preheat the glow plug while taking into account the instantaneous temperature of the glow plug during cooling and the applied voltage in such a way that the temperature required for a restart is achieved within a narrow tolerance range, it is proposed that the renewed preheating time of the glow plug in the case of a repeated starting procedure taking place after the expiry of the safety time should be specified in accordance with a value determined from the glow plug temperature, the instantaneous glow plug temperature being determined from the cooling time of the glow plug after it has been switched off. <IMAGE>

Abstract: A horn speaker comprises an aggregate of a plurality of horn units which are connected through a plurality of pipes to a single horn driver. If each horn units is considered to be an independent sound source, and the arrangement form of the horn units are made linear or curved, the directional characteristic of the horn speaker may be dealt with as an aggregate of line sources along the arrangement form of the horn unit mouths. For example, where the horn units are linearly arranged, the wave front at the mouths as a horn unit aggregate becomes close to plane sound waves, providing a very sharp directivity. 
     A horn speaker of the present invention is applied to vehicle mounted use.

Abstract: The present invention is a cold control for refrigerators. The cold control circuit (14) includes temperature sensitive resistances (20) disposed within the cold box portion (10) of the refrigerator (6). The cold control circuit senses the temperature of the cold box portion by a NTC thermistor (R3) which is disposed in the cold box portion and connected to the control circuit. When the temperature rises above the turn-on set point, the NTC thermistor has a relatively small resistance and activates a transistor (Q2). The transistor is connected to a latching circuit (Q2, R3, R2, R1) which maintains activation of the refrigerator until the thermistor falls below the turn-off point. Another solid state switch of the control circuit activates the refrigerator compressor, such as a transistor (Q1) turning on an inverter in a DC powered refrigerator and a triac (TRIAC 1) directly supplying current in an AC powered refrigerator. For battery powered refrigerators, the cold control includes a clipping circuit (D1, R9) to prevent false activation or de-activation of the inverter caused by ripple voltages. The present invention provides the reliability of a solid state temperature sensor while avoiding the expense of a microprocessor driven system.

Abstract: A magneto-optical disk (23) has a recording layer (4) whereon recorded bits are formed by the magnetic field modulation method and a readout layer (3) whose axis of easy magnetization is parallel to the recording layer (4) at room temperature, and varies to be perpendicular to the recording layer (4) within a predetermined temperature range between room temperature and the Curie temperature. During reproduction of recorded bits a first semiconductor laser (10) emits a heating-use light beam (7) to form the first light spot on the readout layer (3). Thus, a ring-shaped region corresponding to the predetermined temperature range exhibits perpendicular magnetic anisotropy and the recorded bits are copied from the recording layer onto the ring-shaped region. As the first light spot is shifted, the ring-shaped region as a readout window of recorded bits is also shifted. Further, the second semiconductor laser (11) emits a reproduction-use light beam (8) such that the second light spot is formed on the readout layer (3) to overlap the first light spot at a rear portion thereof. Consequently, only one recorded bit copied onto the rear portion of the ring-shaped region can be reproduced. Therefore, high-quality reproduction signals can be obtained from the magneto-optical disk (23) inspite of information high density information recording.

Abstract: A pipeline computer executes instructions in a plurality of pipeline segments where some instructions store into the instruction stream (STIS) STIS operations are detected and the pipeline is purged to avoid the use by the computer system of incorrect data. Detection of a STIS operation is done by comparing the current instruction address (CIA) to the next sequential instruction address (NSIA). A STIS address register (STAR) identifies addresses of all instructions in the pipeline. Although the STAR address is near to the NSIA, it does not necessarily match the next sequential instruction address. The STAR address is compared with the NSIA and performance is enhanced since not until the NSIA has been incremented to overlap the STAR address is a STIS condition is reported.
