Patent DE-3008041-A1 (DE)
Title: Opto-plethysmographic sensor for reflected light from tissue - has mixed transmitting and receiving optic fibre bundles, with transmitter ends proud of receiver ends
Inventor: JOCHENMCZYK CLAUS
IPC: A61B5/024
Filed: 1980-03-03
Abstract: Opto-plethysmographic sensors are used for monitoring the pulse rate or the blood circulation. Prior types of sensors operating with reflected light from tissues are relatively inefficient, resulting in undesirable thermal effects, or require careful adjustment. The new sensor overcomes these drawbacks by intermingling light transmitting and receiving optic fibres bundles. The mixed optic fibre bundles consist of the transmitter fibres (S) and the slightly receding receiver fibres (E). This arrangement avoids direct pick up of light from the transmitter fibres yet results in very efficient light transmission.

Title: Steel prodn. in top and bottom blown converter - with bottom nozzles fed at least periodically with solids-laden oxygen-free gas
Inventor: BROTZMANN KARL DR ING DR ING
IPC: C21C5/35
Filed: 1980-03-04
Abstract: In steel prodn. in a converter having nozzles positioned below the bath surface and a water-cooled lance and/or nozzle positioned above the bath surface, oxygen is supplied from the lance and/or nozzle onto the bath surface and, at least periodically, only an oxygen-free gas, contg. particulate solids for slag forming or heat prodn., is blown into the bath through the subsurface nozzles. The process results in a well controlled low carbon content in the finished steel and reduced iron loss in the slag, e.g. a carbon content in the steel of 0.03% and an iron content in the slag of 12% can be obtd. Additionally, the steel has low hydrogen and nitrogen contents.

Title: Miniature laval nozzles made by electroforming - onto mandrel shaped by profiled turning tool to obtain exact profiles
Inventor: HAYN DIETER DIPL ING
IPC: C25D1/10
Filed: 1980-08-04

Title: Missile launching system on aircraft - has two stage double acting rams at ends to eject missile downwards
Inventor: GRIFFIN DENIS
IPC: B64D1/06
Filed: 1980-08-05
Abstract: The missile launcher has fore and aft ejection rams, pref. two-stage double-acting rams. It has a choked flow gas system to prevent interaction between the rams and avoid back pressure in the breech chambers. Two gas cartridges in two breech chambers supply ejection gas pressure and a third cartridge in a third breech chamber supplies gas for subsequently retracting the rams. The ejection gas pressure also actuates mechanisms for releasing fore and aft missile suspension hooks and crutching assemblies, and for withdrawing an umbilical electrical service plug. Each ram comprises an outer casing, an inner fixed hollow shroud tube and two relatively-moving members with annular pistons that extend telescopically from within the space between the casing and the shroud tube.

Title: Measuring excavator and tractor shovel loadings - using strain gauges on lifting arms at hydraulic force application points
Inventor: PFREUNDT HANS-GUENTHER
IPC: E02F3/42
Filed: 1980-09-20
Abstract: A method and arrangement for measuring loads on diggers and tractor shovels with hydraulic piston and cylinder actuating systems involve the use of strain gauges and display equipment for measurement of lifting force or load only in certain positions of the lifting equipment as determined by position transducers. The arrangement also measures the pressure of the hydraulic fluid in the actuation system. The long damping delays necessary when hydraulic pressure oscillations occur are eliminated. The strain gauges (13,13') are mounted on the actuation system (2) rods (3,4) at points of high bending moment, pref. at points of the highest moments. They can be placed at points on the arms where force is applied by the hydraulic actuators (6,7), pref. above the supporting linkages (14,15).

Title: Quick disconnect hydraulic coupling - has sliding seat for poppet valve to facilitate disconnection under pressure
Inventor: STEUERWALD ALFRED
IPC: F16L37/32
Filed: 1980-10-16
Abstract: The quick disconnect pipe coupling is designed to be disconnected when subjected to internal fluid pressure. The female half of the coupling contains a spring loaded poppet valve (27) which mates with a seat (22) formed in a sliding sleeve (19) loaded by a spring (34). The travel (b) of this sleeve (19) is at least as great as the lift (a) of the poppet. The male half of the coupling has a similar poppet valve (10), also with a lift (a). When the coupling is being connected the second poppet in the male portion remains on its seat whilst the first poppet is pushed against the stop (29). Further movement of the male half pushes the sleeve (19) against the spring (34) for a distance (a). The male half is then fully engaged and by moving the outer sleeve (35), the inner sleeve (19) is returned to its initial position and lifts the second poppet off its seat.

Title: Fibre reinforced flat components esp. helicopter blades - are moulded with continuous weighing of sample impregnated fibres to control adhesive content
Inventor: DOELLINGER ROLF
IPC: B29C70/34
Filed: 1980-10-30
Abstract: Flat or similar components of fibre-reinforced materials are moulded by feeding narrow strips (6) of fibrous material, esp. 2-4 mm wide, from feed reels through an impregnation device (9), where adhesive is applied, into a negative mould (24), where the material is spread out and pressed to form the component. The process is quasi-continuous. Excessive impregnated fibrous strand material projecting from the mould is cut off, weighed (25) to determine the adhesive content. This content is then used for regulating the squeezer device (9) which controls the adhesive content applied in the impregnation of the fibres. Used in mfr. of glass fibre-reinforced helicopter blades, etc. where the content of adhesive is of great importance and the elimination of air bubbles is vital. The arrangement enables controlled mechanical and automatic prodn. of the mouldings to be achieved with better quality and at much higher prodn. rates than conventional manual operations.

Title: Commutation regulator for DC machine - uses detector close to brushes with inter-pole control loop to give minimum sparking
Inventor: RIPKA KARL WOLFGANG DR
IPC: H02K13/14
Filed: 1980-10-31
Abstract: The circuit is used to give close and accurate control of inter-pole excitation in order to operate the machine under optimum commutating conditions. A detector (1), typically a capacitative aerial and band pass filter, receives the HF radiation caused by sparking at the machine brushes. The resulting signal is amplified (2) and passed to a minimum value controller (3). The latter regulates (4) the current flow in the inter-pole winding (GH). The power regulator (4) adjusts the inter-pole current until a minimum HF signal is received by the detector. This regulator may provide direct excitation to the inter-pole winding. Alternatively it may operate as a diverter, or be used to supply current to an auxiliary winding to buck or boost the inter-pole effect provided by the main winding carrying the armature current.

In total, the seating oven is of comparatively light design and is thus also readily transportable. It serves primarily as a heated seat, but can furthermore also be used at least partially for room heating.

Title: Process for extracting tritium from a liquid heavy-water stream
Inventor: DOMBRA ALLAN H
IPC: B01D59/22
Filed: 1981-06-05
Abstract: In a process for extracting protium and tritium from a liquid heavy-water stream, the liquid heavy water is brought into contact, in a column (11) packed with catalyst, with a countercurrent deuterium gas stream in such a way that tritium is transferred by isotopic exchange from the liquid heavy-water stream into the gaseous deuterium stream. The tritium-enriched gas is then passed from the column through a device (13) for removing the tritium, and the tritium-depleted gas is returned to the column, a fraction of the liquid heavy-water stream being shunted off after leaving the column and being passed through an electrolysis stage (14) to generate gaseous deuterium, which in turn is passed to the column, and gaseous oxygen which is discharged or otherwise used. The remaining fraction of the liquid heavy water leaving the column has a reduced tritium content. <IMAGE>
