Patent DE-4123627-A1 (DE)
Inventor: FEHLINGS HERBERT
IPC: B23Q16/06
Filed: 1991-07-17
Abstract: The invention proposes a rotary indexing table which has an annular indexing plate (4) rotatably mounted in a bearing plate (1). A cam plate (9) connected to the bearing plate in such a way as to be fixed in terms of rotation passes through the space enclosed by the indexing plate. Several indexing pins (21) are displaceably mounted in a radially directed manner in the indexing plate, the inner end of the respective indexing pin interacting with the curve of the cam plate. A first stop (27) limits the rotation of the indexing plate in direction of rotation (D) by the outer end of an extended indexing pin bearing against the first stop. A second stop (28) connected to the bearing plate limits the rotation of the indexing plate in the opposite direction to the direction of rotation by the outer end of an extended indexing pin bearing against the second stop. Provided in the area of the first stop are means (30) for pushing in the indexing pin allocated to the first stop towards the cam plate. In the rotary indexing table according to the invention, the indexing pins are controlled via the cam plate, and the two stops arranged outside the indexing plate secure the indexing plate in both directions of rotation. <IMAGE>

Title: Measuring flow of flowing medium within defined measurement vol. - deriving speed of motion of objects in flow from electro=optically acquired electronic image signals
Inventor: SEILER GERHARD ARNOLD DR
IPC: G01F1/7086
Filed: 1992-01-09

Title: Blocking faulty recording on compact disc - using buffer memory during recording that provides delay in which faults can be identified and flags set
Inventor: JUNG JUNG JOO
IPC: G11B7/0055
Filed: 1992-02-12
Abstract: A compact disc (11) recording system processes the analogue signal by a sample=and=hold stage (20) coupled to an A=D converter (30). The data are entered into a digital memory (19). The data are encoded (18) to be received by the laser head control and drive stage (17). Direct digital signals may be entered into the memory. The recording of data onto the disc is delayed by the action of the memory which acts as a buffer. If an error is detected in the data during the delay the recording onto disc is interrupted. A flag is set which prevents the section being used during replay. USE - CD player accepting write-once discs for making own audio recording.

Patent DE-4236088-A1 (DE)
Inventor: WEDI CHRISTOPH DIPL ING
IPC: H04B14/06
Filed: 1992-10-26
Abstract: In DECT-standard telephone connections between a base station and mobile terminals, speech is transmitted in ADPCM-coded form. In this digital ADPCM transmission, bit errors result in strong crackling and background noise. For the duration of this noise the voice channel is muted. In DECT-standard transmission, two test words are formed for error detection. These test words (ACRC, XCRC) are used to assess the strength of this noise. Evaluation of the synchronization word (sync) heading a burst indicates whether the burst was received flawlessly. If not or if certain number, e.g. 10, of the test words in successive bursts are not correct, then a sequence of constant ADCPM words is sent to the ADCPM branch. This sequence can, for example, consist of equivalent 4-bit ADCPM signals representing the binary value "zero" or "one". There can also be a continuous repetition of the last ADCPM word transmitted before the audio muting. This lowers the voice level slowly down to the idle level and prevents the crakling that can occur when the voice channel is suddenly switched off. The muting is cleared when the synchronization word no longer has a number of bit errors greater than a predetermined number or when the test words are correct.
