Abstract: The circuits include a floating diffusion, a source supplying a controllable amount of charge to the floating diffusion and a charge coupled device (CCD) reference register for periodically removing a fixed amount of charge from the floating diffusion. A feedback circuit senses the average voltage at the floating diffusion and adjusts the controllable amount of charge supplied to the diffusion to maintain its average voltage-level constant. The feedback circuit may be employed automatically to control the direct voltage bias at the input electrode of a DDC signal register. It may alternatively be employed to control a radiation source serving as the input to the system, or to operate a circuit for indicating the frequency at which the reference CCD register is being driven, or as an input to a current mirror amplifier.

Abstract: A measuring transformer comprises a measuring conductor carrying the current I.sub.m to be measured, a pre-magnetizing winding which carries a pre-magnetizing current I.sub.v, and a magnetic field comparing means which is exposed to the magnetic field produced by the current I.sub.m and the magnetic field produced by the pre-magnetizing current I.sub.v and is alternately controlled in both directions of saturation. The magnetic field comparing means is a magnetic film which may be anisotropic, operated in the magnetic preferential direction, and have a thickness of at most a few microns. It may be secured to pole shoes of a magnetic core or arranged between a flat measuring conductor and a pre-magnetizing coil of flat cross-section. The measuring transformer can be used as an input transformer in a static electricity meter. In a further embodiment, the output pulses can be obtained directly from the magnetic field comparing means.

The pattern is transferred to the face of the carpet by a doctor blade or, alternately, directly to the carpet face. The trough may be filled with gum in which case the jets spray dye onto the film of gum picked up by the roller. The trough may also be used for dyeing in which case a different color dye is applied by the jets or multiple roll applicator stations may be provided for multi-color and tone effects. Alternately, no trough is used and dye or gum may be applied by the spray jets to the roller.

Abstract: Automatically operating washing machines adjust the washing time, the wash water temperature and the motion, i.e. agitation, of the laundry based on predetermined cycles, such as wash, spin, or rinse, etc. An adjustable program course controls these cycles. Naturally, certain cycles require hotter or colder temperatures than others. The method of the invention varies the program course to cycles requiring hotter or colder temperature, depending on the temperature available. Therefore, if a cycle requires hot water but only cold water is available, another cycle will be chosen or the cycle will run for a shorter time. The automatically operating washing machine has at least one cold water inlet and at least one warm water inlet.
