Title: Automatic recognition of transmitted signal modulation type - uses vector type analysis and microprocessor for evaluation
Inventor: MLAKAR TOMO DIPL ING
IPC: H04B1/18
Filed: 1975-12-09
Abstract: Certain transmitted signal properties, in particular whether frequency or amplitude modulation is being used are automatically analysed by means of a vector representation constructed from samples of the incoming signals and a microprocessor to evaluate this vector. The method used is illustrated for the case when differentiation between frequency and amplitude modulation on a intermediate carrier signal (J) of around 30 KHz is provided. The signal is supplied to an amplitude demodulator and limiter to produce an amplitude demodulated output and to a frequency demodulator to give a frequency demodulated output. Three signals are fed to a coding circuit to give an effective vector representation - in this case two dimensional - of the incoming signal. Samples of this are stored in an intermediate store and processed by a microprocessor using a comparison technique and a pattern store to produce a codeword output representing the modulation type, or other property desired.

Title: Dialysis liquor substitution in blood dialysis - uses cells with flexible membranes to allow balanced replacement
Inventor: STREICHER ERICH DR MED
IPC: A61M1/16
Filed: 1976-07-30
Abstract: Identical volumes of liquor are substituted during blood dialysis. One or two chambers are divided into two compartments by an elastic membrane. Liquid input and output to these is controlled by an 8 way valve. During the 1st. stage a pump removes spent dialysate into the first chamber, at which the flexible membrane pumps out an equal colume of fresh dialysate or fresh substitute soln. from the second compartment. A second pump feeds fresh dialysate into the second compartment of the second chamber. This causes the displacement of an equivalent amount spent liquor from the first compartment, due to the valve arrangement. When the first chamber is filled a pressure rise occurs switching off the second pump, allowing the cycle to continue by reversing the roles of the two chambers. Used in blood filtration and dialysis. The problem is that displaced liquid in the blood has to be deplaced and this is normally done by metering pumps. The system avoids this.
