Patent EP-0370509-A3 (EP)
IPC: B01D71/52
Filed: 1989-11-23
Abstract: The invention pertains to composite polymeric membranes for 
the separation of gas mixtures and a method for their prepa­
ration. The membranes have higher selectivity in the separa­
tion of mixtures He/N₂ and O₂/N₂, suitable mechanical proper­
ties and a high permeability. They consist of a polymeric 
porous base made from poly(2,6-dimethyl-1,4-phenyleneoxide) 
and a polymeric selective separation layer formed from a 
polyamidoimide of the general formula I, 
  
and  
n = 140- 220,  
or from an interpolymeric equimolar complex of PAI-1 with 
polyvinylpyrrolidone, or from an aromatic polyimide of the 
general formula II, 
  
and n = 150-230,  
or of the general formula III, 
  
where n = 150-240,  
or from polymeric imides of the general formula IV, 
 
 
  
or also from their copolymers with styrene, methyl methacry­
late, methyl acrylate, and dimethylaminoethyl methacrylate.  
     The method for the preparation of these composite polymeric 
membranes consists in saturation of a porous base of 
poly(2,6-dimethyl-1,4-phenyleneoxide) with an inert organic 
solvent, e.g. aliphatic C₇H₁₆ to C₁₀H₂₂ aliphatic hydro­
carbons or their mixtures, drying, and coating with a 1 to 
25 mass-% solution of the selective separation polymer in an 
organic solvent incompatible with the organic liquid, e.g. 
N-methylpyrrolidone, N,N-dimethylformamide, and/or N,N-di­
methylacetamide.

Title: Ring dispenser
IPC: B65G47/88
Filed: 1990-06-02
Abstract: A ring dispenser comprising a rotating rod 
having an acme thread along one portion thereof and a 
helical coil spring at a dispensing end thereof feeds 
individual rings to a ring transfer device located at the 
dispensing end of the rod. The rod is rotated by a motor 
and the rings are automatically separated and directed to 
the end of the rod where a sensor detects the presence 
of the ring and stops the motor. When the ring transfer 
device is ready to pick up a ring, the motor starts again 
and a ring slides off a conical tip of the rod onto the 
transfer device by rotation of the rod. The rings have 
diameters greater than the separation between the 
individual threads of the rod so that the rings move on 
the crests of the threads and are out of engagement with 
the thread roots. The spacings between the convolutions 
of the coil spring are greater than the thickness of the 
rings so that the rings move on the rod surface as the 
rings approach the dispensing end of the rod.

Title: Method and apparatus for measuring phase accuracy and amplitude profile of a continuous-phase-modulation signal
IPC: H04L27/20
Filed: 1990-01-11
Abstract: A method and apparatus for determining the phase and 
amplitude accuracy of continuous-phase-modulated signals is 
described. A modulated RF signal generated by a transmitter 
is down converted to a relatively low intermediate frequency 
which is filtered and sampled by a high sampling rate 
analog-to-digital convertor. a digital signal processor 
processes the digital signals to produce a measured 
amplitude function and a measured phase function 
corresponding to the modulated RF signal. From the measured 
amplitude and phase functions, an ideal phase function 
corresponding to the modulated RF signal is calculated and 
synthesized. The ideal phase function is compared to the 
measured phase function to determine the phase function from 
which the modulated RF signal phase error and frequency 
error are computed.

Inventor: BAR-DAVID ISRAEL
IPC: H04B1/69
Filed: 1995-11-14
Abstract: A spread spectrum code pulse position modulated
communication system is disclosed. The communication system
includes a spread spectrum code pulse position modulated
receiver that compensates for the delay spread of a
transmission medium, such as a wireless radio channel of a
local area network. Delay spread may cause signal
components of one transmitted spread spectrum codeword to
spill over into chip positions of adjacent symbols, causing
intersymbol interference, or into chip positions on
quadrature channels of a given symbol interval, such as in
a QPSK implementation, causing interchip interference. The
disclosed receiver decodes a transmitted spread spectrum
code pulse position modulated signal in the presence of such
delay spread, utilizing a tentative symbol estimator to
sample the matched filter data. The tentative symbol
estimator will assign a weight to each potential symbol
value, taking into account the cross-rail or bias influence
caused by the residual coupling between the signals on
quadrature channels for a given symbol duration. In
addition, the disclosed receiver includes a mode sifter
which evaluates the weighted values for each symbol estimate
and assigns final estimates to each symbol value, taking
into account the influence of codewords transmitted during
one or more successive symbol intervals on one another.
