Title: Spark gap control in ignition system for internal combustion engine
Inventor: VOGEL MANFRED
IPC: F02P7/03
Filed: 1997-04-18
Abstract: The circuit arrangement is used to control at least one spark gap, especially for ignition systems of internal combustion engines in cars. It has an ignition coil controlled through a transistor power end stage. The secondary winding of the coil is connected to earth on one side and to the spark gap on the other side. At least one sweep diode is wired in the secondary circuit and can be triggered backwards to suppress the spark at switch-on. This diode (24) is wired in between the secondary winding (20) and the spark gap (12). With positive polarity of the switch-on voltage, the anode is connected to the secondary winding and the cathode to the spark gap. With negative polarity, the connections are reversed.

Title: Automatic balancer for high frequency mixer in spectrum analyser
Inventor: ERICKSON BRUCE A
IPC: H03D7/00
Filed: 1997-09-09
Abstract: The balancer (54) in a single-pulse HF mixer (52) mixes the HF input signal (53) with the LO-energy local oscillator signal (55) to achieve an intermediate frequency signal. It is connected to an in-phase conductor (58) and an out-phase conductor (59) and through these the signals pass to a difference amplifier (62) which inputs their amplitude and to a difference phase shifter (64). A signal combiner (66) combines the amplitude and phase inputs from the in-phase and out-phase signals, determined and controlled by a microprocessor. This intermediate frequency circuit is inexpensive to make. It almost completely neutralises local oscillator shunt and thus ensures cost-effective accurate spectrum analysis.

Abstract: The invention relates to a composition for use in a dishwasher which is provided in the form of a tablet. The inventive composition is characterized by a base composition which essentially carries out its function during the main cleaning cycle of the dishwasher, and is also characterized by at least one particle. Said particle has at least one core that comprises at least one substance which essentially carries out its function during the rinse cycle of the dishwasher. The particle also has a coating which, for the most part, completely surrounds the core(s). Said coating comprises at least one compound whose solubility increases with a declining concentration of a specific ion in the surrounding medium. The at least one particle is arranged in or on the tablet in such a way that the surface of the particle(s) is, at most, partially in direct contact with the surface of the base composition surrounding this/these particles. In order to prevent the coating from substantially dissolving or to prevent the coating from substantially detaching from the core(s), the concentration of the specific ion in the local surrounding of the particle(s) is sufficiently high until the tablet has, for the most part, completely dissolved. The invention also relates to a method for conducting a dishwashing cycle in a dishwasher while using the inventive composition.
