Filed: 1982-07-27
Abstract: Zum Korrigieren der Ausrichtung eines Elektronenstrah­
les, mit dem eine Auftreffplatte (12) beaufschlagt wird, wird 
die Strahlquelle (10) elektronenoptisch auf eine zentrale, 
kreisförmige Öffnung (27; Fig. 4) einer Ausblendplatte (28) 
abgebildet. Zu ausgewählten Zeiten wird das Bild der 
Strahlquelle auf eine zweite kreisförmige Öffnung (35) in der 
Ausblendplatte abgelenkt. Mittels eines Ablenk-Joches (30) 
erfolgt ein genaues Ausrichten des Bildes der Strahlquelle 
auf diese zweite Öffnung. Deren Durchmesser entspricht 
etwa der Halbwertsbreite W der Stromdichteverteilung des 
Bildes der Strahlquelle in dieser Öffnung. Das genaue 
Ausrichten des Bildes der Strahlquelle auf die zweite Öff­
nung erfolgt durch kleine Verschiebungen des Bildes. Diese 
werden beendet, wenn der die zweite Öffnung durchfließen­
de Elektronenstrom einen Maximalwert annimmt. Dann wird 
der Elektronenstrahl wieder zu der zentralen kreisförmigen 
Öffnung der Ablenkplatte gelenkt. Deren Durchmesser 
beträgt mindestens etwa das doppelte der Halbwertsbreite 
W der Stromdichteverteilung des Bildes der Strahlquelle in 
dieser Öffnung. Dadurch bleiben die zur Ausrichtung des 
Elektronenstrahles vorgenommenen Verschiebungen des 
Bildes der Strahlquelle ohne merklichen Einfluß auf den die 
zentrale Öffnung durchfließenden Elektronenstrom, der zur 
Auftreffplatte gelangt.

Patent EP-0118771-A3 (EP)
Title: Compression and expansion of digitized voice signals
IPC: H04B1/66
Filed: 1984-02-09
Abstract: Apparatus and a method are disclosed for digitizing a voice signal as it occurs and the digitized signal is compressed and stored for subsequent reconversion to a voice signal at a latter time. Binary words derived from digitizing the signal in an analog-to-digital converter represent the voice non lineary and are first linearized by a first processor and then stored in a first memory until a block of binary words are assembled. Next the block of binary words are transferred to a second buffer memory and a second processor compresses it using time domain harmonic scaling processing which extracts the pitch of the original voice and also compresses the voice frequency spectrum to affect a 2:1 reduction in the number of stored binary words representing the digitized voice signal. This reduced amout of data is then upsampled by a factor of four using linear interpolation to derive a pseudo higher sample rate required for further processing using continuously variable slope delta modulation processing which yields one binary bit out for every binary word processed. The resultant bits are assembled into eight bit words and then stored in a third memory. Another binary word representing the pitch is added and the result is a 4:1 compression of the original digitized data. The compressed digitized data is stored in a bulk memory. Thereafter, more digitized samples of the voice signal undergo this same processing. Compressed digitized voice signals may be reconverted to a voice signal for playback by processing the digitized and compressed voice signals generally in the reverse order. Playback speed control may also be accomplished without changing the pitch of the voice. To double the playback speed the time domain harmonic scaling processing is deleted in playback, thus leaving the frequency spectrum compressed and a 2:1 reduction in binary words representing the digitized voice. To slow the playback speed the digitized voice signals undergo modified TDHS processing.

Title: Multipurpose clamping tool for processing workpieces, in particular wooden ones
IPC: B25H1/00
Filed: 1984-03-06
Abstract: A multipurpose clamping device for a modular tool comprise first and second clamping jaw members each of which has a front face with an aligned modular tool clamping receiving opening. The jaw members include base portions with side rails extending therethrough at spaced lateral locations providing means facilitating the movement of the jaw members toward and away from each other without canting. The clamping device is associated with each opening to clamp the tool in position. The clamping device may be used as a vise by inserting a vise clamping jaw into each opening of each member and in such instance the spindle is advantageously threaded to each member to permit members to move upon driving of a threaded spindle member. The device may also be used for example as a support for a hand drill which may have its forwarded end inserted in the opening and clamped therein so as to line a tool receiving chuck therein which may be rotated and align it with a tailstock center carried by the other jaw member.
Patent EP-0128423-A3 (EP)
IPC: B65G47/08
Filed: 1984-05-24
Abstract: Stacks of generally dish-shaped, nested plastic articles 
are gripped and transferred from elevated, horizontally ad­
jacent chutes comprising circumferentially disposed, axially 
extending supports, which are open at both ends to permit 
articles to be both fed thereto and removed axially there­
from, to a conveyor disposed at a lower level. A transfer 
arm, mounting stack gripping receivers, which pivot on the 
transfer arm, is swung in an arcuate path and the receivers 
are moved relative to the transfer arm, responsive to swing­
ing movement of the transfer arm, such that the receivers 
travel from a first position, horizontally axially aligned with 
said chutes and axially intermeshed with the supports, in a 
path having a first axially linear increment, then a down­
ward arc to rotate said stacks substantially 90°, and finally 
a vertically linear path to deposit the stacks on the conveyor. 
The receivers are radially contracted to peripherally grip 
stacks of articles in the chutes when the receivers are in the 
first position, and are radially expanded to peripherally 
release the stacks when the receivers have moved the 
stacks to the conveyor.

Title: Blind signature systems
IPC: H04L9/00
Filed: 1984-08-13
Abstract: A cryptographic system allows, in one exemplary use, a supplier (101) to cryptographically transform a plurality of messages responsive to secret keys; the transformed messages to be digitally signed by a signer (102); and the signed transformed messages returned to the supplier (101) to be transformed by the supplier (101), responsive to the same secret keys, in such a way that a digital signature related to each original message is developed by the supplier (101). One important property of these systems is that the signer (102) can not determine which transformed message received for signing corresponds with which digital signature-even though the signer (102) knows that such a correspondence must exist.

Patent EP-0136019-A3 (EP)
IPC: B65D33/38
Filed: 1984-08-09
Abstract: The invention relates to a drainage bag primarily for urine 
but also for other liquid drainage, and particularly although not 
exclusively to a urostomy bag.  
     There has long been a problem in draining urine bags. Users 
who are not dexterous, and particularly those who are old or 
infirm, find it difficult to satisfactorily manipulate present bag-­
emptying arrangements when emptying the bag. Present empty­
ing arrangements involve a plug and tube, or a folding tube with a 
clip, or a valve or tap. It is often difficult to aim the bag or tap (10) 
outlet directly into the eventual urine receptacle.  
     These problems are largely or wholly overcome by providing 
siphon tube for emptying a drainage bag.
