Patent DE-3151260-A1 (DE)
Title: Probe for measuring the moisture content of quenching oils
Inventor: WERNKE FRANZ
IPC: G01N33/28
Filed: 1981-12-24
Abstract: The probe (16) has a measuring chamber (21) situated outside the quenching bath (12) and sealed from the ambient air. In the latter, a measuring chamber region (36) filled with a gas atmosphere and an exchange region (45) with a stream of quenching oil flowing through it are in mutual communication. In the exchange region (45), the quenching oil, which is continuously fed by a circulating pump (31) from the quenching bath (12) and flows back into the latter, transfers its moisture content to the gas atmosphere. In the measuring chamber region (36), a humidity meter (37) measures the moisture content of the gas atmosphere. As a result, both the dissolved water and free water content of the quenching bath (12) are transferred, on the one hand, to the gas atmosphere with great reliability in a continuous exchange process, measured very precisely in the oil-free measuring chamber region (36) by a humidity meter which functions perfectly and reliably in the gas atmosphere and either indicated by means of an indicating instrument and/or converted into measurement and switching signals. Consequently, a warning signal can in turn be given in good time in critical cases before the quenching bath (12) foams over. <IMAGE>

Patent DE-3242165-A1 (DE)
Title: Container tipping and pivoting appliance
Inventor: SCHATZ WERNER
IPC: B66F9/19
Filed: 1982-11-13
Abstract: The invention is used in the material handling area inside a production facility, in particular at a work place, where parts have to be removed from box pallets for machining or testing and have to be stored again in the box pallets. The containers are put by means of the appliance into the most favourable position for removal. This is done by lifting and pivoting to the side. Since the lifting and pivoting device is not built on a stationary frame but on a normal fork-lift truck, the containers can thus also be moved or fetched for this purpose. Furthermore, the appliance can be used first at this work place and then at another work place or machine tool, since it can easily be shifted like a fork-lift truck. The description below supplements our sketch, sheet 1 of 3, Fig. 2 or Fig. 1. A lifting frame (2) is welded in place between the supporting arms of a fork-lift truck. Sliding in the lifting frame (2) is the lifting slide (3) which is lifted by a hydraulic cylinder. The pivoting platform (4) is laterally mounted on the lifting frame and is driven in a pivoting manner to the side by a hydraulic cylinder. Supports on the fork-lift truck provide for the requisite stability. The supporting arms of the platform reach over the supporting arms of the fork-lift truck. Consequently, the appliance remains very low when picking up loads and can move under all containers. The lifting and pivoting movement is effected electro-hydraulically with mains connection. To fetch and ... Original abstract incomplete. <IMAGE>

Title: Torsional vibration damper with friction segments
Inventor: ANDERS PETER
IPC: F16F15/123
Filed: 1983-04-28
Abstract: The invention relates to friction segments between the cover plates and the hub disc of a torsional vibration damper which - inserted into the apertures in the cover plates - both produce the friction force and assume the guidance of the torsion springs. Guidance of the torsion springs in a manner which is substantially free from wear is thereby achieved; it is at the same time possible to produce high friction forces since the friction segments are arranged at a long distance from the axis of rotation. The friction segments can be manufactured as compound components, the friction material being applied to a punched base element consisting of sheet metal.

IPC: C04B7/43
Filed: 1983-11-18
Abstract: Method and apparatus for burning fine grained material, particularly for the manufacture of cement clinker whereby the product quality is enhanced. At least a portion of the exhaust gases from the kiln at a temperature of about 1000 DEG  to 1300 DEG  C. are cooled by passing them through a steam generator to a temperature of about 200 DEG  to 300 DEG  C. At least a portion of the noxious substances such as alkali chlorides and sulfur are condensed out of the gas stream as well as possibly some mineral particles such as partially deacidified kiln dust. The materials condensed out of the gas are separated in the steam generator by means of periodic or continuous cleaning of the heating surfaces of the steam generator. The steam which is generated in the generator is conducted to at least one prime mover such as a steam turbine or a steam motor for the purpose of producing electrical or mechanical energy. In this way, the economic feasibility of cement clinker burning systems equipped with bypass devices is considerably increased by exploiting the high thermal potential of the bypass gases.

Title: Protection circuit for a safety apparatus in order to increase the protection level
Inventor: ZIELASKO HORST
IPC: H02H3/33
Filed: 1984-01-21
Abstract: The invention relates to a protection circuit for a safety apparatus in order to increase the protection level, based on the principle of an earth-leakage current protection circuit, preferably for mobile use in the form of a plug or plug socket. In this case, the significant fact is that the earth conductor circuit (PE) is also monitored for an earth leakage current. However, in this case it can arise that a short-circuit occurs in the external earth conductor circuit which prevents triggering of the associated safety apparatus. In order to preclude this short-circuit case, an inductor (9) having an iron core (10) is additionally arranged in series with the primary winding (6) of the summing current transformer (4) in the earth conductor circuit (PE). The inductor (9) is on the one hand characterised by a resistance which is as low as possible and on the other hand it also has an impedance which, in the unsaturated state, is at least twice as great as the impedance of the primary winding (6) of the earth conductor circuit. As a result of the increase in the short-circuit resistance through the inductor (9), blocking of the triggering of the safety apparatus is impossible. <IMAGE>
