Patent DE-2820645-A1 (DE)
Inventor: BROWNING IBEN
IPC: B60R16/037
Filed: 1978-05-11
Abstract: An apparatus and method wherein speech or other signals are sampled during a time slice of approximately 1/30 second and spectrum analysis is performed on the samples, producing measures of amplitude in several frequency bands with each frequency band being characterized by a binary digit indicating the presence or absence of significant amplitude. The binary digits are collectively referred to as a sonogram. Sonograms for several time slices are then concatenated, randomized and decoded using an n-tuple technique to produce a pattern corresponding to the current speech signal. This pattern is learned by superimposing it on an existing vocabulary entry and is subsequently recognized if it is sufficiently similar to one vocabulary entry and different from all others.

Title: Vibrating sieve with two superposed layers - has resilient link members between two layers ensuring extra vibration of lower finer sieve
Inventor: PUDERBACH GERHARD
IPC: B07B1/46
Filed: 1979-07-23
Abstract: The two vibrating sieves are mounted one above the other to make up the sieve unit. These have different mesh widths and are linked together by resilient rubber elements. The vibrator is rigidly fixed to one of the sieves i.e. is preferably mounted on the upper sieve, so that the lower sieve is suspended from the upper sieve by the resilient elements. It is possible by using only one vibrator to vibrate the sieves at different amplitudes according to their work load. This is advantageous because the fine mesh of the lower sieve means a greater build-up of material requiring more drive energy, which would be wasted if also applied to the upper sieve.

Patent DE-2941223-A1 (DE)
Inventor: LINK MANFRED
IPC: B41J1/24
Filed: 1979-10-11
Abstract: The type carrier (1) has the letters for upper case in the region of a first basic position and the letters for lower case in the region of a second, diametrically opposite basic position. In both basic positions, the type wheels are shortened. The type carrier (1) is mounted on a drive shaft (3) which is actuated by an actuation motor (2) and bears at the other end a coding disc (4). The coding disc (4) is scanned with photoelectric beams (LS1, LS2, LS3, LS4). Two of the photoelectric beams (LS3, LS4) supply phase-shifted periodic scanning signals for determining the angle of rotation of the type carrier (1). Two further photoelectric beams (LS1, LS2) each supply a zero signal for detecting the two basic positions. As a result, it is possible to rotate the type carrier into the adjacent basic position after each printing of a character, and thus to make the printed character visible. For deflection and resetting of the type carrier, in each case angles of at most 90 DEG  are necessary so that the printing speed is high. <IMAGE>
