Patent DE-2544231-A1 (DE)
Title: Light barrier detector esp. for flat ribbon objects - has angled parallel beams cutting plane of object which deflects beam to next sensor in series
Inventor: SCHMALL KARL-HEINZ
IPC: G01D5/34
Filed: 1975-10-03
Abstract: The light-barrier arrangement for detecting flat or strip-type objects consists of a number of light source (1-10) and associated photosensors (1a-10a). The light sources and/or the receivers are activated in sequence and provide an output signal as long as there is no obstruction present (17). Instead of the individual light beams being focussed onto their normally opposite sensors (1-1a) to form a series of parallel, horizontal beams, the light path is deflected at an angle so that it falls onto the light sensor next in the series (1-2a). Since the falt strip object (17) has such a small cross-sectional area which meant poor detection with the former system, the angled beam arrangement provides a higher sensitivity. Alternatively, the emitters and sensors may be arranged on the same side with a retro-reflective plane on the other side of the target area.

Title: Blood sample extractor for centrifuging - is easier to handle and vents air from behind piston
Inventor: SARSTEDT WALTER
IPC: A61B5/15
Filed: 1976-11-23
Abstract: A cylindrical extractor for blood, one end face of which has a connection for a cannula, has a transverse wall with a central bore, and a piston guided, airtight, in the cylinder. The central bore guides the piston rod, and the transverse wall forms a rigid stop for the piston. The piston rod is releasable from a boss behind the piston, which is received into a counter-bored spigot in the dividing wall. The space between the piston seal and the zone of contact of the piston boss with the counter board spigot, is vented of air when the piston is retracted. The nipple forming the connection fro the cannula, tapers down to a tip sealed by a thin film, and is accommodated in a taper socket of a closure cap. This has a corresp. socket on its outer face with a spike at its bottom which bursts the film when this socket is applied to the nipple. An alternative embodiment has the nipple sealed by a solid tip extending beyond a circular notch at which the tip can be broken off. The venting arrangement prevents the compression of air in the cavity behind the piston during centrifuging, with the risk that when centrifuging is stopped, the pressure of the air makes the blood sample unusable.
