Title: Recovery and reuse of cobalt compounds from carbonylation processes
Inventor: DIESSEL KARL-HEINZ DR
IPC: C01G51/04
Filed: 1981-02-03
Abstract: A method for the recovery and reuse of cobalt compounds from carbonylation processes starts from the waste salt which, in addition to alkali metal halide or alkaline earth metal halide, may contain approximately from 0.1 to 5 % by weight of cobalt and approximately from 2 to 20 % by weight of organic substances. The waste salt is stirred with water while being acidified, whereupon the insoluble organic residue is removed mechanically. The cobalt-containing solution is filtered and, by addition of oxalic acid, the cobalt is precipitated as cobalt oxalate. The precipitate is filtered off, dried and decomposed thermally with the admission of air, which gives the mixed oxide CoO.Co2O3. The recovery efficiency, based on cobalt, is 95 % by weight and more.

Title: Apparatus for preparing a bituminous mixture including the use of old asphalt
Inventor: FORTMANN JUERGEN DR ING
IPC: E01C19/10
Filed: 1981-03-13
Abstract: The invention relates to an apparatus for preparing a bituminous mixture also using old asphalt. The apparatus comprises a drying drum, a compulsory type mixer and the usual conveying, metering and bunker devices. According to the invention, the drying drum is fired in counter current, and the size-reduced old asphalt is propelled from the discharge side into the region of the throwing and deflecting devices in the interior of the drum, without it being directly taken up by the hot flue gases of the burner flame. In this way, it is possible to incorporate more than 20% of old asphalt into the mixture without impairing the bitumen fraction. The throughput of the installation is not reduced by the increased addition of old asphalt.

Title: Hand-held motor-driven chain saw
Inventor: MEHLITZ DIETER
IPC: B27B17/02
Filed: 1981-04-13
Abstract: The object of the invention is to improve hand-held motor-driven chain saws such that the housing equipped with the carrying and operating elements is able to remain in the same basic position in each cutting direction; this results in a high degree of operating and functioning safety, since the carrying and operating elements can be optimally adapated and designed; due to the changeable fitting of the handle on one side, easy adaptation for either right- or left-hand use is possible. The cutting direction is adjusted by turning the chain blade or the chain on the housing about the blade longitudinal axis. In this case, the connecting shaft between the motor housing and the chain drive can be the axis of rotation, or the entire unit, consisting of motor, chain drive and blade, is rotatable in the housing. A particularly simple and well-arranged design results when the motor is installed in the longitudinal direction of the blade connected to the worm gearing between motor and chain. <IMAGE>

Title: Clamping device for a round bar guided axially in a housing
Inventor: FREITAG SIEGFRIED
IPC: F16M11/26
Filed: 1981-05-22
Abstract: Locks, stands, tool manufacturing, tensioning and clamping, special-purpose-machine construction, machine tools and safety tension and compression connections (couplings), to name but a few examples, involve the problem of slowing down, positioning and clamping in position, in all directions, a round bar, which can move axially in a housing, in a simple, rapid and smooth manner that is to say avoiding stepped latching portions with clearance, and they further involve the problem of releasing the clamping position again. The invention solves this problem in that there is provided, in the housing (4) or in a ring (41) connected in a positively locking manner to the housing, a cone surface (42) against which there is held, such that it is pressed by an elastic member (2), a clamping body (1) which rests, on the other side, on the round bar (5). The clamping body (1) can be moved away from the cone surface (42), counter to the action of the elastic member (2), by means of a ring element (3) enclosing the round bar (5). <IMAGE>

Title: Flexible supporting element in the form of a strap, a rope or the like
Inventor: FRANKE HEINZ
IPC: D07B1/16
Filed: 1981-07-23
Abstract: The invention relates to a flexible supporting element in the form of a strap, a rope or the like, in particular for lifting or securing loads. A strap of this type has an inlay part absorbing the tensile stress and made of a textile material and a protective sheath intended for the inlay part and made of plastic, rubber or the like. The protective sheath is mostly subjected to very high notching or cutting stresses, in particular if large, sharp-edged loads have to be transported. There is therefore considerable risk of damage to the protective sheath and thus also to the inlay part of textile material determining the carrying capacity. According to the invention, therefore, a multiplicity of small reinforcing bodies are to be embedded in the protective sheath. The cutting resistance of the reinforcing bodies is a multiple of the cutting resistance of the protective-sheath material. Here, the protective sheath can loosely surround the inlay part or else be applied as a fixed component in the form of a coating. The reinforcing bodies prevent the protective sheath from being destroyed down to the inlay part by sharp-edged loads, pinching or the like. <IMAGE>

Patent DE-3133834-A1 (DE)
Title: Drive arrangement
Inventor: SOMMER GORDON MAURICE
IPC: F16D48/06
Filed: 1981-08-27
Abstract: The invention discloses an improved high-performance drive coupling for a motor, comprising a motor which is connected non-positively to the driven device via a viscous coupling which can be operated selectively by the application of hydraulic pressure. An improved electrically activated control valve serves to control the hydraulic control pressure applied to the coupling and has a control circuit for the actuation of the control valve in order to accelerate the driven device as required. In some applications, a plurality of these drive arrangements can be employed to drive a common device and, in this arrangement, the control devices for the pressurisation of the coupling can be positioned in between in order to achieve a certain progressively delayed pressurisation of the various couplings. The control circuit can also contain a safety correction device which serves to disconnect the coupling in order to decouple the motor from the driven device in the event of abnormal operating conditions. <IMAGE>

Title: Process for improving metallurgical slags
Inventor: PIRET JACQUES
IPC: C21C5/36
Filed: 1981-09-29
Abstract: The invention relates to the improvement of metallurgical slags in order to enable them to be used in a ground state as a constituent of covering powders in continuous casting. For this purpose, the slags from air-refining are mixed, as far as possible in the molten state, with fly ashes on the one hand and silica or slightly clay-containing sand on the other hand, the additives containing less than 70 % of silica. The mixture is made or maintained liquid by heating, and is then reduced with added carbon in an arc furnace. The molten slag is then decanted and cooled, while metallic by-products are taken off by decanting. Actual mixture compositions illustrate how the invention is carried out. The product made in this way gives, after comminution to at least 50  mu m, a covering powder which meets the requirements of continuous casting.
