Title: Device for mounting a plug in the opening of a panel, a support or the like
IPC: H01R13/74
Filed: 1989-10-24
Abstract: The invention relates to a device for securing a receptacle housing, positioned at the end of a cable, in an opening of a wall. The receptacle housing and the opening have a generally rectangular cross-sectional area and can be connected with each other in at least two positions, offset by 90 DEG  from each other. The receptacle housing has detent springs which engage with the wall, from behind. A securing strap is fixed on the cable which is connected to the receptacle housing. The other end of the securing strap is connected to a cover. The cover can be mounted on the contact side of the receptacle housing. The cover can be guided through a groove-shaped recess while the securing strap is pushed through a side wall of the opening. The alignment between receptacle and opening, without impairment of the passage of the securing strap, is achieved in that the opening of the wall only has recesses for the securing strap of the cover in two side walls, located at right angles to each other. The two side walls determine a vertical and a horizontal routing of the cable to the receptacle housing.

Patent EP-0351950-A3 (EP)
Title: Use of plasma to immobilize protein on polymeric surfaces
IPC: C12N11/08
Filed: 1989-06-07
Abstract: The present invention relates to a method of 
immobilizing proteins on a polymeric matrix by means of plasma 
activation and an apparatus and process for the use of such 
material. The protein mixture is applied to the surface of the 
polymeric matrix with or without the addition of a crosslinking 
agent. It is then placed into a plasma generator, wherein the 
functional groups on both the protein and the matrix molecules 
are activated to form free radicals. Upon returning from their 
high energy state, the free radicals form covalent bonds 
between the proteins and between the protein and the polymeric 
matrix. Using this method, the proteins are nonspecifically 
immobilized on the surface of the polymeric matrix. The method 
can be utilized to immobilize proteins on the surfaces of 
polymeric membranes, polymeric beads, polymeric tubes and 
polymeric plates. The immobilized protein has high biological 
activity and stability.

Patent EP-0366342-A3 (EP)
IPC: H04L12/56
Filed: 1989-10-18
Abstract: A switching system is described in which routing information, 
which may be associated with packets originating in cellular calls, is divided 
into information which does not change as the subscriber crosses a cell 
boundary, and information which does change as the subscriber crosses a 
cell boundary. Routing procedures associated with the information which 
does not change as the subscriber crosses a cell boundary are established 
and stored in the memory of the switch at the beginning of the call. 
However, routing procedures associated with the information which does 
change as the subscriber crosses a cell boundary may be derived from the 
header information of each packet as it arrives at the appropriate portion of 
the switch.

Patent EP-0336913-A3 (EP)
IPC: B60T13/66
Filed: 1989-03-28
Abstract: The invention relates to a process and arrangement designed, through 
braking, to keep constant the speed of a motor-vehicle when travelling on 
downhill slopes. With the aim of producing simple actuation and 
deactuation of the constant speedkeeping function, the invention is 
characterized principally in that the constant speedkeeping function 
commences upon actuation of a driver-activated brake control (17). In 
connection with this, the lowest vehicle speed is stored as a target value 
within the memory of a control unit (1). The actual vehicle speed is then 
regulated towards the target value through activation of the vehicle brakes 
(4). Only once an ordinary driver-activated control (19) is activated, is the 
specified regulation towards the target value suspended.

Patent EP-0397385-A3 (EP)
Title: Error correction method and apparatus
IPC: H03M13/00
Filed: 1990-05-02
Abstract: For forward error correction, the least significant bit of each 
multibit symbol is encoded before transmission according to a block code 
that has an over-all parity bit. Since even syndromes can be produced by 
only an even number of errors and odd syndromes by an odd number of 
errors, a Chase decoder at the receiver considers either all double errors or 
all single errors and all triple errors that include the least reliable symbol in 
making the corrections to arrive at the most likely transmitted sequence.
