Title: Linear actuator with an electric motor
Inventor: PFISTER JEAN-FRANCOIS
IPC: H02K7/06
Filed: 1984-03-26
Granted: 1987-12-23
Abstract: A simple, inexpensive, and effective linear actuator design comprises a motor adjacent to a speed-reducer, with the driven stem of the speed-reducer passing through the rotor of the motor. The stem has one bearing at one end of the reducer and its second bearing at the end of the motor, in a bearing part likewise serving as a bearing for the rotor. The distance between the two bearings is increased, and the second bearing includes a socket which has a radial elasticity owing to the fact that it is monolithically joined to the fixed bearing part via a thin portion. This second bearing part is advantageously of synthetic material. The rotation of the stem actuates a driven linear-motion part, which is prevented from rotating and which executes a translatory movement.

Title: A method for recovering metal values from materials containing copper and/or precious metals
Inventor: HOLMSTROM SVEN AKE
IPC: C22B1/08
Filed: 1984-09-28
Granted: 1989-03-02
Abstract: The invention relates to an improvement in a method for recovering metal values from copper-containing and/or precious-metal containing materials which also contain antimony and/or bismuth in such high quantities as to render working-up of the materials with conventional metallurgical processes difficult or impossible. In accordance with the improvement, the material is subjected to a chlorination volatilization process in a manner to bring the antimony and/or bismuth content of the material to a predetermined low level acceptable for the continued working-up of the material in conventional process stages, while maintaining the metal values of the material in a substantially unaffected form. The volatilization process is best carried out at temperatures of between 450° C and 750° C, preferably between 550° C and 650° C.The chlorination process can be carried out on materials included in the group: sulphidic or oxidic-ore concentrates, matte, speiss, oxidic and metallic intermediate products. In certain cases it is convenient to convert the material to another form within the group, for example the matte, prior to carrying out the chlorination process.

Granted: 1989-01-12
Abstract: The apparatus comprises a plurality of stages having screw presses, the material passing out from the outlet side of the stages being passed by a transfer duct to the inlet side of the following stage. Each stage has a speed adjustable independently of the speed of the other stages. Compared with known screw presses, the advantage exists that following each treatment in a stage, by means of an opening in the transfer duct, the material can be measured, checked or subjected to an additional treatment. The number of stages can also be adapted to the material being processed and there is also a relatively large freedom with regards to the arrangement of the apparatus.

Abstract: The invention relates to a receiving arrangement 4-1 for SHF signals, comprising a rectangular waveguide filter 5 formed from resonators 10-1 to 10-4 arranged in cascade, a SHF signal arrangement 6 containing a microstrip circuit and a microstrip to waveguide filter transition connection to this circuit.Generally, such a receiving arrangement is not suitable for use in radiators comprising a partly shown polarization converter 3 with two such receiving arrangement 4-1 each receiving one of two mutually orthogonally polarized signals. When the prior art receiving arrangements are used in these radiators, the channel separation is inadequate.According to the invention, an adequate channel separation is obtained by providing the microstrip to waveguide filter transition in the waveguide filter and matching the filter 5 thereto. As a result thereof, the receiving arrangement 4-1 becomes more compact and has a very low reflection and, in addition, it is no longer necessary to adjust the transition to the waveguide filter 5.Preferably, dimensioning is realized by the choice of the size in the axial direction of the end resonator 10-4 and/or the choice of the dimensions of the coupling aperture which connects the end resonator 10-4 to the adjacent resonator 10-3.
