Patent EP-0091375-A3 (EP)
IPC: H03K5/13
Filed: 1983-04-01
Abstract: Apparatus is provided for delaying an electrical signal 
present at a selected node. The apparatus includes a first 
multiplexer 71 which connects one of eight inputs I₀-I₇, to an 
output terminal 75, an adjustable length delay line 72 is 
coupled between each pair of input terminals I₀, I₇ and the 
input signal is then supplied to the first input terminal of the 
multiplexer 71. The delay lines 72 are trimmed to create the 
desired time delay between input terminal 74 and output 
terminal 75.  
     For larger adjustments of the time delay for the signal is 
supplied to input terminal 74 and supplied to another 
terminal 78 connected to the input terminal I₀ of another 
multiplexer 61. Logic gates 62-67 are connected between 
each pair of terminals I₀-I₆ of the second multiplexer 61. A 
coarser adjustment of the time delay than achievable with 
the delay lines 72 is made by switching of an appropriate 
input terminal of the second multiplexer 61 to the output 
terminal 69 of the multiplexer 61. In this manner one or more 
gates 62-67 may be added to the path delay of the input 
signal supplied to terminal 74.

Abstract: A switch and valve assembly for inflating or deflating a 
pair of bladders mounted in the back and seat regions of a 
vehicle seat. The assembly houses two normally-closed 
valve assemblies and two normally-open electrical switch 
assemblies, with two pushbutton-actuated stems adapted to 
selectively either partially open the valve assemblies by 
partial depression of the pushbuttons to thereby bleed-off 
fluid under pressure from respective bladders, or to fully 
open the valve assemblies while closing the switch assemb­

Title: Clutch
IPC: B61C9/52
Filed: 1984-12-13
Abstract: A shifting coupling which is preferably provided for the travel mechanisms of overhead conveyors, and which operates in a positively engaging manner counter to a spring which acts in the disengagement direction. The coupling projections or engaging members, which are provided on a coupling flange, are controlled with the aid of two sleeves which are movable relative to one another. Those ends of the sleeves which butt against one another are provided with oppositely extending conical surfaces. Control balls can be pressed into the wedge-shaped recess which results between the two conical surfaces. The control balls press the two sleeves apart in order to engage the coupling. A control sleeve, which is provided with inner conical and annular surfaces, serves for the radial movement of the control balls. During the engagement process, the control sleeve is resiliently prestressed in such a direction that the conical surface thereof contacts the control balls in the direction of coupling engagement. The actual engagement process is not triggered until the positively engaging, intermeshing coupling members are aligned with one another, and the two sleeves are driven apart by the control balls, to the extent that a spring tension acts thereupon.

Abstract: Disclosed is a scan apparatus (4) which provides an 
interface and control signals between a secondary com­
puter (1) and data locations in a host computer (2). The scan 
apparatus (4) functions independently of the normal opera­
tion of the host computer (2). Scan-out is performed trans­
parently to the operation of the host computer (2). The host 
computer (2) is constructed using circuits on semiconductor 
chips (7-1. 7-Y). The semiconductor chips (7-1, 7-Y) are 
organized in blocks (3-1). Chips within each block (3-1) 
include scan apparatus (4) which controls the scan opera­
tions in connection with that chip. The scan apparatus in 
each chip is connected through two I/O pins to a clock lines 
and to a bidirectional scan data line. The scan apparatus on 
each chip includes a multimode sequencer so that each chip 
in each block can be independently performing scan 
sequences. The block scan apparatus and the secondary 
computer perform the functions of requesting a scan 
sequence for transmitting the scan data.

Abstract: A system is provided for locating a mobile telephone 
subscriber within the range of a wide geographic surface (5), 
consisting of a plurality of mobile telephone exchanges 
(CM A , CM B ,...CM N ) each of which controls an area and 
comprises means for monitoring the presence of mobile 
telephones within its own area, said exchanges being 
connected to a common broadcasting center (CN) capable of 
receiving request for the location of mobile telephones from 
each of the said exchanges and transmit them (for example 
via satellite) to all the exchanges of the system. Upon such a 
request, the mobile telephone exchange in whose area the 
paged mobile telephone is located will send information on 
its own identity and on that of the mobile telephone 
subscriber to the common centre, whereupon the common 
centre will transmit this data to the exchange which issued 
the request, or directly to this originating exchange. The 
originating exchange is then able to make the connection to 
the concerned subscriber.
Patent EP-0196046-A3 (EP)
IPC: G06T3/40
Filed: 1986-03-24
Abstract: An optical and electronic scan produces an image com­
posed of binary value pixels. An automatic picture compres­
sion routine reduces the number of pixels in the image. A 
first stage four to one reduction in the number of pixels is 
achieved by treating each mutually exclusive four pixel unit 
as a separate set. A binary value is assigned to each four pi­
xel set. That binary value is assigned to a single pixel in a 
first output image. The same process is repeated a second 
time to provide a final output image that has one-sixteenth 
the number of pixels as has the original input image.  
     The value assigned to each four pixel unit set is a 
weighted function of the binary value of each of the sixteen 
pixels in a four pixel by four pixel subfield in which the unit 
set is centered. The greatest weight is give to the center pi­
xels, that is, to the four pixels of the unit set. Lesser weight 
is given to the peripheral pixels. Among the peripheral pi­
xels, lesser weight is given to the four corner pixels than is 
given to the eight side pixels between the corners.  
     In the weighting process, the significance of the binary 
value of the sixteen pixels in the subfield is in part a function 
of the total pattern of the pixel values in the subfield.

Abstract: A method for fabricating a bipolar transistor having a base 
doping variation of less than 20% is disclosed. A 
polysilicon base contact bipolar transistor is formed up to 
the point just prior to the intrinsic base-emitter 
formation. The intrinsic base-emitter opening is then 
reactive ion etched through the polysilicon base contact 
layer down to and into a single crystal silicon body (10, 20, 30) 
thereunder, whereby the surface of the single crystal 
silicon is damaged. A silicon dioxide layer is then grown on 
the exposed and damaged single crystal silicon to convert 
the damaged silicon surface into a silicon dioxide layer. 
The silicon dioxide layer is removed by chemical etching to 
expose undamaged single crystal silicon. A screen silicon 
dioxide layer 50 to 500 Å ± 10%, e.g., 180 Å, is then formed 
on the thus exposed undamaged single crystal silicon. The 
intrinsic base region (140) is then formed by ion implantation 
through the screen silicon dioxide layer, the emitter region (150) 
is formed within the intrinsic base region and electrical 
contact is made to the various elements of the bipolar 
transistor.

Title: Process for isothermic quick-dyeing of wool
IPC: D06P1/00
Filed: 1986-12-12
Abstract: The dyeing of wool with reactive dyes in a strongly acid medium (containing sulfuric acid) requires no longer acceptable, long heating-up times (50-60 minutes) in order to obtain level dyeings. It has now been found, according to the invention, that by rapidly heating up the dyebath which contains the dyes of the vinylsulfonyl type and also all the ingredients, except the acid, to the dyeing temperature together with the material to be dyed and then metering in the sulfuric acid under isothermal conditions at the dyeing temperature it is possible to obtain very level and very fast dyeings in a significantly shorter overall dyeing time. Carbonized wool can be dyed without prior neutralization.
