Title: Capillary blood sampler - with partial closure of rear end eliminating meniscus errors
Inventor: SARSTEDT WALTER
IPC: A61B5/15
Filed: 1979-02-17
Abstract: A device to extract blood samples by capillary action consists of a hollow, slightly conical point with capillary action at least at its forward end. A tubular holder, made integral with the capillary or transparent plastic, is joined to it by two diametrally opposed webs. A rod which extends beyond the rear end of the holder has at the forward end a pyramidal point which closes most of the rear opening of the capillary but leaves gaps for air to escape so that the capillary action is not impeded. If no temporary closure were provided, the blood would form at the rear end a meniscus of varying shape, depending on the temp. and viscosity of the blood, so that dosage errors could be caused. This is eliminated by the new capillary.

Title: Increasing bit rate transmission over two=wire link - by transmitting in turn at three different rates, with duplex operation
Inventor: STREHL HERBERT DIPL ING
IPC: H04Q11/04
Filed: 1980-08-01
Abstract: The signals to be sent or received over a digital communications link with two wires (Z) originate, or end, in four wire systems (I,II;I',II'). Operation is at three different frequencies which are selected by frequency switches (FW1,FW2). The first switch selects either base frequency (f1) or a higher frequency (f2,f3). With base frequency selected transmission can be in both directions. A digital switch (DG) discriminates w.r.t. direction. If the first switch (FW1) selects the higher frequency it makes connection to a second switch (FW2) which selects between the two higher frequencies (f2,f3). In this case transmit and receive each have their own frequency. The proposed transmission method gives a higher bit rate without disturbing cross talk or noise emissions, and can be added retrospectively to a digital transmission link.
