Patent DE-2621175-A1 (DE)
Title: Implanted mechanism for lengthening limb - has telescopic members secured to bone sections by screws and held apart by gradually advanced ratchet
Inventor: WESTERHOFF ERHARD DR
IPC: A61B17/80
Filed: 1976-05-11
Abstract: The appliance is used for increasing the length of a patinet's arm or leg. The existing procedure requires screws to be left projecting through the skin which can lead to infection. The present invention avoids this by connecting the two parts of the cut bone by telescoping members having an internal ratchet mechanism. In a preferred realisation, the outer telescopic member has a U-profile piece with a removable cover across: it carries the lodging for the pawl. The inner telescopic member carris the ratchet, which is graduated in 2mm steps (the daily movement being induced by external traction and detected by stethoscope.

Title: Automatic fluid chemical analyser - has feeder with spaced projections for non-changed location of sample containers
Inventor: KELLER WALTER
IPC: G01N35/02
Filed: 1976-06-18
Abstract: The unit for handling samples in an automatic analyser of fluids or gases eliminates expensive electronic circuitry. The machine comprises a conveyor chain with a meander track exhibiting projections for the sample holder. The filled container is transferred from the chain to the belt conveyor by a feed mechanism after passing the scanning station for identification. The analyser includes a main and a treatment track, the latter equipped with reagent containers following a U-shaped path. The button-shaped projections of the chain are provided with a flat for specific positioning of the containers so that coded markings can be sensed by a detector pin connected to the fibre-optic unit of a photoelectric scanner.

Title: Homopolar exciter for brushless generator - has additional field winding on exciter rotor for generator field temp. compensation
Inventor: FROEHLICH GUENTER ING GRAD
IPC: H02K19/38
Filed: 1976-06-23
Abstract: The exciter (7) is of the homopolar type with axial main field winding (13) between two stator sections (9). The rotator carries the armature winding (15) which is connected to the generator (1) field winding (2) through rectifying diodes (19). In parallel with the rectified exciter output there is an additional exciter field winding (14) located between the rotor sections and augmenting magnetomotive force from the main excitation winding. The purpose of this addional winding (14) is to increase the generator excitation voltage to compensate for the rise in generator field resistance due to heating. The operating characteristics of a homopolar machine are such that in this application an increase in load resistance leads to an increase in generated voltage. Thus self compensation for generator field resistance increase is provided.

Title: Recycled activated sludge thickener - with mechanical thickened sludge removal by scraper blades from trommel
Inventor: STEINECKE HELMUT PROF DR ING
IPC: C02F11/126
Filed: 1977-10-25
Abstract: A trommel for a thickening process for recycled activated sludge in biological sewage treatment systems is fed with a sewage/sludge mixture with a high percentage of suspended solid particles. The particles deposited on the outside of the filter cloth of the trommel are removed only mechanically by converging scrapers and a stripping lip.

Patent DE-2833115-A1 (DE)
Inventor: LACHENAL DOMINIQUES
IPC: D21C3/26
Filed: 1978-07-28
Abstract: In the process employing sodium hydroxide and oxygen, with two cooking stages and intermediate defibring, the second stage is replaced by a cooking operation in the presence of an alkaline solution of peroxide containing a stabiliser for the peroxide, at atmospheric pressure. This avoids both the contamination effects of the kraft process, while obtaining a pulp of comparable quality, and the costly plants required by the sodium hydroxide-oxygen process.

Title: Heartbeat frequency determination system - derives currents from palms and feeds them to frequency meter
Inventor: LESSEN LOTHAR VAN DIPL PHYS DR
IPC: A61B5/332
Filed: 1978-09-26
Abstract: The system determines the heartbeat frequency during athletic training on an ergometer.

Title: Electrical terminals for socket connector - has pinch screws which are restrained by springs forming part of body moulding
Inventor: LICHT HARRY
IPC: H01R4/30
Filed: 1979-01-11
Abstract: The object of the proposed design is to prevent inadvertent loosening of the pinch screws forming part of the wire end terminals. Each terminal (2) comprises a metal block with a hole (3) to receive the incoming wire end. A tapped hole at right angles to the axis of the cable hole (3) takes the pinch screw (4). A part of the insulation body (1) of the socket assembly is arranged as a leaf spring (5) which bears against the screw head (4). The friction between spring and screw is sufficient to prevent loosening of the electrical connection in service. In the preferred design, the springs and body are a single piece moulding. Two springs (5a, 5b) are provided for each screw to give a centering action. There is little wear between springs and screw thus enabling connections to be changed without deterioration.
