Patent DE-4111357-A1 (DE)
Inventor: SPIES KLAUS PROF DR ING
IPC: B65G31/04
Filed: 1991-04-09
Abstract: An arrangement for transferring castable material without pipes or conduits from a feeding point to a destination, particularly in underground mining. The arrangement includes a driven centrifugal wheel with blades. The centrifugal wheel is radially open and is surrounded in the manner of a jacket by an endless housing belt which is guided on guide rollers. The portion of the centrifugal wheel which is radially open is bordered by the guide roller which causes the housing belt to contact the centrifugal wheel and by the guide roller which raises the housing belt from the centrifugal wheel. The material is radially discharged in a concentrated manner through this radially open portion. The material is supplied axially to the centrifugal wheel through a feed tube and enters through a discharge opening of the feed tube on the vertical level of the blades into the centrifugal wheel.

Title: Millimetre wavelength frequency division for LF prodn. - using feedback loop with frequency divider, harmonic generator and N-harmonic mixer to achieve required frequency
Inventor: BUECHLER JOSEF DR ING
IPC: H03B21/01
Filed: 1991-04-12
Abstract: An intermediate frequency, fs, is produced by mixing the primary oscillator (5) frequency, fOSZ, with n-multiplied harmonics of a doubled intermediate frequency feedback signal, 2fs, using an n-multiple harmonic mixer (4a). The feedback signal is obtained using a feedback loop (1) that amplifies, doubles and re-amplifies the intermediate frequency using two amplifiers (3a, 3b) and a diode frequency doubler (2), and is used in conjunction with either a diode-gated noise source or an auxiliary oscillator (6) to generate the necessary harmonics. The intermediate frequency is given by fs = fOSZ/(2n + 1); a typical set of values for a sixteen-fold frequency division being 85 GHz, 5 Ghz and 8 for fOSZ, fs and n respectively. ADVANTAGE - Simple, cost-effective arrangement in which only low frequency (fs and 2fs) signals are amplified in feedback loop.

Title: Mechanically actuated draw chuck
Inventor: ENBERGS BERNHARD
IPC: B23B31/26
Filed: 1991-08-21
Abstract: The mechanically actuated draw chuck has a hollow body (1) with a taper mouth bore to accept the shank of a tool or tool holder. Arranged co-axially in the bore is a draw component (4) with fingers (5) which expand into a groove in the hollow end of the shank when the draw component moves inwards.Resting against abutment faces (4a) of the draw component are pins (3) which extend outwards through inclined holes in the chuck body.

Title: Mounting laminated core on shaft of small electric motor - eroding surfaces of shaft in electrical discharge machining process to increase diameter
Inventor: IVKOVIC ZORAN
IPC: H01R39/14
Filed: 1991-10-24
Abstract: The process is used for fixing the laminated iron core of a small electric motor to a shaft such that the shaft diameter is large enough for the loading and is secured adequately. The core is fixed in a pressing operation in which an interference fit is obtained.

Title: Prodn. of wire and sections by hot rolling doubly refined steel - involves using pairs of rollers alternately to allow rollers to cool.
Inventor: FIGGE DIETER DIPL ING
IPC: B21B27/10
Filed: 1992-03-20
Abstract: Wire and metal sections in doubly refined steel are produced by hot rolling of continuously cast bar. The bar passes between two pairs of horizontally mounted rollers and then between two pairs of vertically mounted rollers.

Title: Guided missile light source array encoding - using integrating sensor in conjunction with scanning sensor for identification of interfering sources by comparison between two sensing channels
Inventor: RIEGER ROBERT DIPL ING
IPC: F41G7/30
Filed: 1992-06-17
Abstract: The light source array encoding involves using an integrating image sensor, such as a CCD, to integrate a pixel over a shorter or longer section of the imaging period which may lie between zero and e.g. 20 ms. A scanning sensor such as a thermal imaging device samples each pixel for a few microseconds, commencing at an instant which depends on its position in the image. Without pseudo-noise modulation the array is visible to both sensors, and with prolonged pseudo-noise modulation, to neither. In the missile body position of the scanning system it is seen by the integrating sensor only, and otherwise by the scanning sensor only. ADVANTAGE - The array is better distinguished from other light sources within the field of view, being always visible to one sensor despite the modulation.
