Abstract: A mechanical timer to control multiple steps of a process comprising a first cam having a shaft, and a second cam having a shaft, wherein the shaft on the first cam extends into the shaft of the second cam. The rotational relationship between the first and second cams determines the length of time for at least one process step. First and second user adjustable elements are attached to the first and second cams. These user adjustable elements do not require any disassembly of the mechanical timer by the user or require any tools. A plurality of switches engage the cams to control various process steps.

Abstract: A cleaning system that utilizes an organic cleaning solvent and pressurized fluid solvent is disclosed. The system has no conventional evaporative hot air drying cycle. Instead, the system utilizes the solubility of the organic solvent in pressurized fluid solvent as well as the physical properties of pressurized fluid solvent. After an organic solvent cleaning cycle, the solvent is extracted from the textiles at high speed in a rotating drum in the same way conventional solvents are extracted from textiles in conventional evaporative hot air dry cleaning machines. Instead of proceeding to a conventional drying cycle, the extracted textiles are then immersed in pressurized fluid solvent to extract the residual organic solvent from the textiles. This is possible because the organic solvent is soluble in pressurized fluid solvent. After the textiles are immersed in pressurized fluid solvent, pressurized fluid solvent is pumped from the drum.

Abstract: A method for calibration of a path length variable being used for navigating a terrestrial vehicle. The path length variable is measured by determining the number of revolutions of a wheel. For calibration of this value, two speed values are ascertained. A first speed value is determined using the number of revolutions of the wheel and a second speed value is determined using at least one external position sensor. One of the speed values is classified in a plurality of classes, and a calibration value in a class is ascertained using the speed values from this class.

Abstract: It is proposed to design a compression-type refrigeration system of a motor-vehicle air-conditioning unit having a supercritical process, with a compressor (6), driven by an electric motor (5) with motor-control device (12), a gas cooler (27), an expansion member (8) and an evaporator (9) and also connecting elements for a circulation of a refrigerant, in such a way that the heat loss of the motor and/or of the motor-control device is essentially dissipated to the refrigerant. In particular, the refrigerant may flow around the motor and/or the motor-control device. This results in especially efficient cooling of the components, as a result of which their heat loss is reduced at the same time. Furthermore, in order to achieve a high efficiency of the entire unit, provision is made for the superheating of the refrigerant at the inlet of the compressor to be kept at a virtually constant level by a controlled expansion member.

Abstract: A fuel tank (1) possesses, for the introduction of fuel, a filler pipe (5) which is led through an orifice (6) of the fuel tank (1) with all-round clearance. The orifice (6) is sealingly closed by means of a sleeve (4) bearing against the fuel tank (1) and against the filler pipe (5). The orifice (6) can thereby be made relatively large, so that it can be additionally used also as a service or assembly orifice after the sleeve (4) has been removed. The number of orifices necessary on the fuel tank (1) can be reduced as a result, so that both the maximum filling quantity and the permeation tightness can be increased.
