Abstract: In a fastening device for the dust-tight fastening of filter bags in a separation plate between crude gas and purified gas chambers in dust-laden gas filters, an elastic nipple, formed as a slit ring, is inserted into the open end of each filter bag. In order to produce the radially acting fastening and sealing force, a clamping ring (6) is swingably supported in the nipple (5), said ring being provided with flats (6a) on two sides which are opposite each other. On each side of the slit in the nipple (5) two protrusions (5b) are provided between which the clamping ring (6) is locked in installed condition. In unlocked upward swung condition upon the installing or removal of the nipple (5), the clamping ring (6) can be used as handle, either without or with attached filter supporting basket (5c).

Abstract: The user of a remotely controlled, powered manipulator is provided with audible feedback signals which provide useful information relating to the force and speed of the motor. An audio tone is generated and is frequency modulated by a signal which corresponds to motor speed. The tone is amplitude modulated by a signal corresponding to motor force thus providing the user with an intuitively interpretable feedback signal having a speed-proportional pitch and force-proportional volume. In the case of an electric motor, voltage and current can be monitored to provide speed and force signals respectively. Additional modulation means are disclosed for introducing a force-proportional warble component to said tone.

Abstract: CO2 and H2CO3 can be added to the drinking water and water for other usage in the household and for small establishments on the one hand and to any irrigation water for house plants floods or hobby gardens on the other hand, in a simple and purposeful manner and in different concentrations. This makes it possible, on the one hand, to use relatively large, commercially available normal compressed CO2 gas cylinders even in the household and small establishments and to supply the various CO2 users in the household from this compressed gas cylinder. These users can also include domestic appliances for the direct preparation of CO2-containing beverages, the carboniser thereof being connected to the compressed gas cylinder. For the addition of different quantities of CO2, a plurality of mutually independent devices for impregnation of the water with CO2 can also be provided directly before the removal point or the user. The impregnation devices can supply the various lines or appliances in the household in different concentrations via separately controllable devices. As a result, depositions of mineral substances in domestic appliances and machines can be greatly reduced, with economical usage of CO2, and large proportions of the mineral substances present in the drinking water can be utilised for direct absorption by the organism, for example with the drinking water.

The granular detergent compositions herein unexpectedly provide through-the-wash softening benefits comparable to what can be obtained from the utilization of conventional cationic rinse- softeners. An additional benefit originates from the «dry-softening» feel of the composition herein as compared to the «greasy» feel conferred by conventional cationic rinse softeners.

Abstract: A converter or running-key for generator producing pseudo-random sequences under the supervision of a secret or confidential key or code is substantially formed by a combination device containing a memory circuit and a feedback circuit. Periodic digital sequences are summed in an adder circuit, and the thus obtained composite digital sequence is separated in a divider circuit. A part of this composite digital sequence is used as a digital feedback sequence which is fed to an input of the same adder circuit through the feedback circuit comprising an auxiliary digital memory device or storage and an auxiliary logic circuit. In this manner, the desired memory and feedback is achieved which results in more complicated or complex pseudo-random sequences. In an advantageous exemplary embodiment, a substitution block is inserted as the auxiliary digital memory device or storage. This substitution block can be implemented by a commercially available read-and-write memory (RAM).
