Patent EP-0272554-A3 (EP)
Title: Foldable partition
IPC: A47K3/36
Filed: 1987-12-10
Abstract: The foldable partition for shower surrounds and the like consists of at least two adjacent wall elements which are connected to one another by a folding joint. A hinge pin is attached to each of the wall elements at the top and bottom side; two adjacent hinge pins are attached by a double joint strap. A sealing strip, which is attached to the outside of the one wall element and the inside of the other wall element, passes transversely through the hinge gap formed between the two wall elements. Seen in the axial direction of the folding joint, at least two sealing strips are provided which extend in opposite directions. When swivelled in any direction, the sealing strip is thus wound up at the abutting side of the one wall element and unwound at the abutting side of the other wall element so that the sealing strip alone adopts the function of that forced guide which ensures that, when the two wall elements are swivelled, the angle formed between each wall element and the double joint strap remains essentially the same. <IMAGE>

Patent EP-0248542-A3 (EP)
IPC: G06F3/039
Filed: 1987-05-06
Abstract: The invention relates to an improved optical transducer 
capable of converting translational movement of the transdu­
cer over a surface into corresponding position coordinates 
despite the incorporation of degraded optical components. In 
accordance with one feature of the invention, the optical 
transducer transmits light onto an array of optical contrasting 
indicia and detects in which one of at least three levels of light 
intensity the intensity of light reflected by the array of indicia 
falls. In accordance with another feature of the invention, the 
optical transducer is programmed to interpolate between 
first and third positions when the data derived at the second 
position is ambiguous. The raw optical data derived from the 
reflection of light by the array of indicia is processed using 
look-up tables to detect the direction of incremental move­
ments of the optical transducer in the X and Y directions.

Abstract: An electrical device such as a metal-oxide-semiconductor 
field effect device has a layer (10) of a first material (eg 
SiO₂) having an edge (A) and an overlying layer (13) of a 
second material (eg a metallisation). The edge is configured to 
define an indentation or projection (12) which presents a number 
of edge surfaces (B, C...H) arranged at different relative 
orientations to one another. Coverage of at least one of the 
edge surfaces will be substantially continuous even if an 
anisotropic deposition technique is used to deposit the 
overlying layer (13). Each indentation or projection may have a 
fractal form (Fig 4b) including a number of identical edge 
patterns.

reduziert wird. Formstoffbrücken zwischen Formkastenwand und 
hohen Modellbereichen nahe der Formkastenwand können sich nicht 
mehr aufbauen. Zwischen Formkastenwand und hohen Modellbereichen 
nahe der Formkastenwand wird eine einwandfreie und gleichmäßige 
Verdichtung erzielt.

Title: Process for the decoration of textile fabrics
IPC: D06M16/00
Filed: 1988-05-05
Abstract: In this process, the decorative effects are prefabricated on the textile material and then treated by means of enzymatic hydrolysis, the carrier material consisting of cuts of fibre material which are not enzyme-resistant and/or more enzyme-resistant than the carrier material. The carrier material is removed either completely or from areas defined in terms of pattern in the course of the prefabrication of the decorative effects, without destroying the fibre, without employing mechanical stress and while reducing the use of environmentally harmful aggressive media. Further processibility of the degradation products is ensured.

Patent EP-0339131-A3 (EP)
Title: Electric switch with counteracting electro-dynamic forces
IPC: H01H1/54
Filed: 1988-11-24
Abstract: A switch has contacts constructed so that an 
electro-dynamic force is created by the current flowing 
through the switch which tends to maintain the switch 
in a closed state. This force counteracts other 
electro-dynamic forces which tend to open the switch. 
The contact design is particularly adapted from use 
in a single pole-double throw switch having a contact 
arm that is movable between two fixed contacts. The 
electro-dynamic force compensation exists between 
the contact arm and whichever one of the fixed con­
tacts the contact arm is against. The fixed contacts 
also include arc runners so that any arc that develops 
as the contacts separate eliminates electro-dyanmic 
force which tends to maintain the switch in a closed 
state.

Title: Process for preparing an edible dispersion and products of such process
IPC: A23D7/005
Filed: 1988-10-25
Abstract: A process for preparing an edible plastified dispersion 
comprising a continuous fat phase and a dispersed 
aqueous phase, characterised in that it comprises the 
steps of: 
   (a) working buttermilk with a non-dairy fat to 
obtain an emulsion, and,    (b) mixing the emulsion obtained in step (a) with 
butter under mild conditions.     
     By employing such a process, it is possible to obtain a 
melange product in which the characteristic 
microstructure of butter has not been destroyed. 
Moreover, only a proportion of the total fat content of 
the final product need be passed through the churn, 
enabling a higher production figure to be obtained with 
a fixed size of churn.

IPC: H03M13/00
Filed: 1988-02-05
Abstract: An error-correcting method and apparatus for a block of data 
(D0 to D511) provided with an error-correcting parity (C1, C2) for 
error correction and an error-checking parity (EDC) that can be used 
to generate a syndrome for error-checking, in which error correction 
is carried out by the use of the error-correcting parity (C1, C2) and 
then an error check is carried out by the use of the error-checking 
parity (EDC) thereby to increase the reliability of the error-­
corrected data. Error information produced by the error-correction 
process using the error-correcting parity (C1, C2) is utilised to 
correct the syndrome used in the error-checking process, so as to 
execute the respective operations in parallel and reduce the required 
data processing or through-put time.

Title: Data demodulation apparatus
IPC: H03H17/08
Filed: 1989-05-26
Abstract: A data demodulation apparatus applicable to a 
playback input signal from a digital recording 
apparatus, which executes A/D conversion of the input 
signal with a sampling period that is equal to the bit 
separation of that signal, and obtains phase data for 
reproducing the phase of the clock signal component of 
the input signal each time that a "1" state bit is 
detected in a sampling period. For each sampling 
period, or set of successive sampling periods, data 
values are derived which respectively represent a 
number of bit positions of the input signal within that 
period and the presence or absence of "1" state bits 
in the period, and these data values are converted to 
serial form to respectively constitute a reproduced 
clock signal and a detected data signal.
