Patent EP-0199685-A3 (EP)
IPC: G03C5/40
Filed: 1986-02-12
Abstract: The invention provides a method of forming a 
stencil for screen printing machines, comprising a 
screen (3) stretched in a frame and a layer (11a, 
11b, 11c) affixed to said screen and provided with 
a printing pattern, by exposing a light-sensitive 
film (10) which comprises a light-sensitive layer 
(11) applied to a layer substrate (12), with an image 
corresponding to said printing pattern and then developing 
the light-sensitive layer of the exposed light-sensitive 
film, thereby to produce dark portions corresponding 
to portions illuminated during the exposure, 
said method being characterised in 
   (a) that the said dark portions are removed by an 
etching or bleaching process from the layer (11), 
thus leaving the substrate bare (5c, 6c) to form 
the pattern to be printed, the remaining layer 
(11a, 11b, 11c) forming margin lines against 
the desired printing pattern;    (b) that the said substrate (12) with the remaining 
unetched or unbleached layer, in order to form 
margin lines against the desired printing pattern, 
is placed against the screen (3) stretched in 
the frame, such that the said remaining layer 
is caused to interact with the screen;    (c) that, after said interaction between the remaining 
layer (11a, 11b, 11c) and the screen (3) has 
been established, only the substrate (12) is 
removed; and    (d) that a stencil intended for screen printing machines 
and provided with a layer having a printing pattern 
is formed.

Title: Electrostatic spray device for coating powder
IPC: B05B5/03
Filed: 1987-02-16
Abstract: An electrostatic spray device for coating powder has a powder channel, the downstream end of which has a spray opening for the spraying of the coating powder. At least one gas channel with at least one gas outlet opening is arranged substantially in the radial center of the powder channel upstream of its spray opening, the gas outlet discharging axially in the direction toward the spray opening. At least one electrode, around which gas from the gas channel flows, is located in the gas outlet opening, the downstream electrode end of the electrode terminating substantially at the downstream end thereof. Within the powder channel, directly in front of its spray opening, a funnel-shaped powder channel section is provided for compacting the powder concentration. The gas stream injects electric charges into this section, which the stream of gas has taken up from the electrode. The spray opening preferably has the shape of a slot.

Title: Amplifying circuit arrangement
IPC: H03F1/32
Filed: 1987-04-10
Abstract: A robust amplifier consists of two delay lines 12 and 23 linked by a number of discrete amplifiers 13. Distortion correction is carried out by distortion feed forward. This is achieved by sampling the output of each amplifier 13 at a coupler 17 and then subtracting this sample from the input signal to later amplifiers (13) along the delay line 12 at directional coupler 19. As a result each discrete amplifier's distortion is corrected by all of the following discrete amplifiers (13) in the amplifying circuit.

Patent EP-0294950-A3 (EP)
IPC: G06F17/27
Filed: 1988-05-18
Abstract: A method of facilitating the alphabetical 
dictionary sorting, by computer, of words based upon characters 
from a multilingual alphabet, especially the repertoire of 
characters defined in the new standard alphabet known as ISO 
8859/1. This invention uses an encoding scheme (33) to determine 
the language dependent sort orders for the characters defined in 
ISO 8859/1. This encoding scheme removes the dependency of 
sorting on the character set's internal collating representation. 
This method allows the same sorting software to support many (if 
not all) of the languages supported by the alphabet. By storing 
the language dependent sort orders as data files (36), the 
sorting software is immune to the user's language and hence is 
highly portable. The number of languages supported is directly 
proportional to the number of data files available.

Title: Recording and play-back device, particularly a telephone answering machine
IPC: H04M1/65
Filed: 1989-10-08
Abstract: Recording/replay devices in most cases contain a control device and an operating device for controlling the functional facilities arranged in the device. The control device handles a number of different tasks in this arrangement, for example controlling automatic function sequences, monitoring the functional facilities, ensuring that in each case only one command, which can be input at the operating device, is executed, activating the functional facilities in the correct order and so forth. Unintentional operation of an operating control, particularly when automatic function sequences are being controlled, can disturb the automatic function sequence or initiate an unwanted function sequence. To increase the operational reliability and enhance the ease of operation, at least one operating control can be latched and the period and/or number of actuations of the operating control or controls is evaluated for unlatching. The recording/replay device provides the user with the possibility of controlling in the latched and unlatched condition in a simple manner. This makes it possible, for example, to prevent the unintentional erasure of a recording, preferably of a message text or announcement/trailer text in a telephone answering machine. <IMAGE>
