Title: Agitator
Inventor: LEHMANN JUERGEN DR ING
IPC: B01F15/00
Filed: 1985-05-31
Abstract: An agitator, in which an agitator element immersed in the medium to be stirred describes a circular trajectory by means of a revolving eccentric acting on a support for the agitator element, the main axes located in the horizontal plane of the support not changing in direction, is to be developed in such a way that uneven movements of the carrier are avoided, the intention being to absorb simultaneously both the tangential forces and substantial axial forces. Moreover, the arrangement according to the invention is intended to enable gentle stirring. To this end it is provided according to the invention that the carrier is a planar member, which can be moved in the circular trajectory by the revolving eccentric, lies in a horizontal axis and is supported by a fixed mount with the interposition of rolling elements, the rolling elements additionally serving for fixing the direction of the main axes of the member.

Title: Device for controlling the supply of gas to a gas-consuming appliance
Inventor: SOEMER HEINZ
IPC: F23K5/00
Filed: 1985-07-09
Abstract: The invention relates to a device for controlling the supply of gas to a gas-consuming appliance, in particular a gas oven, having shut-off members arranged in series in the conduit in the device, one of which shut-off elements, as a shut-off device, only shuts off or completely frees the supply of gas and the other, as a control device, determines the flow rate by intermediate positions of the control element.

Patent DE-3529447-A1 (DE)
Title: Steering rack-type steering gear
Inventor: KORNPROBST FRANZ
IPC: B62D3/12
Filed: 1985-08-16
Abstract: In a steering rack-type steering gear having a contact device which loads the steering rack towards the drive pinion and has a roller bearing which rolls on the steering rack and is received in a displaceable pressure element, a first spring which exerts a smaller degree of pretensioning and a second spring which has a higher pretensioning force are provided. The first spring acts directly on the pressure element whilst the second spring is arranged as a storage force in the pressure element and comes into effect on the steering rack in the case of relatively high disturbing moments. The steering rack is not supported directly on sliding faces of the pressure element, bypassing the roller bearing, until the second spring is overcome.
Patent DE-3534260-A1 (DE)
Title: Method for thermal drying of temperature-sensitive materials in rotary drums as well as devices for implementing this method
IPC: F26B11/02
Filed: 1985-09-26
Abstract: The method is characterised by the cooling of the smoke gas from the combustion in a first indirect cooling stage and in a downstream second, direct cooling stage. The heat-flow content from the first cooling stage is transmitted to the material being dried by contact, the content from the second cooling stage by convection. The heat generation is regulated by a characteristic measured variable at the end of drying by adding a further characteristic measured variable of the contact heat transmission. By influencing the heat transmission conditions as well as by supplying colder gas, the heat flows are regulated and permitted temperatures are observed. The devices for implementing the method envisage both heat transmission systems flowed through by heat transfer medium and installation parts which are acted on directly by smoke gas and in good contact. The installations have one or two rotary drums. In the return vapour lines, preventive fire protection arrangements are installed. The heat storage capacity of hot installation parts is kept low.

Title: RF surgical instrument with power control from the surgical handle
Inventor: HAGEN UWE DIPL ING
IPC: A61B18/12
Filed: 1986-01-15
Abstract: The surgical handle (2) of the RF surgical instrument possesses first and second actuation elements (16, 18) which are preferably designed as touch contact switches. These actuation elements (16, 18) are connected to the adjustment member (24) of the RF generator (22) of the RF surgical instrument in such a way that actuation of the first actuation element (16) causes increased supply of the RF power at the output (26), whereas actuation of the second actuation element (18) causes reduced supply of the RF power at the output (26). The surgeon can thus adjust the desired RF power himself from the surgical handle (2) during an operation; this applies both to the operative state "cutting" and to the operative state "coagulation". <IMAGE>
