Patent DE-3122409-A1 (DE)
Title: Device for the non-invasive continuous analysis of the blood oxygen content
Inventor: HEINE GEROLD DIPL PHYS DR RER
IPC: A61B5/00
Filed: 1981-06-05
Abstract: Device for the non-invasive continuous analysis of the blood oxygen content, characterised in that it possesses a measuring head which is applied to the skin, illuminates the latter and disperses the reflected light into a spectrum, and an electronic evaluator which determines the distance between two intensity minima (1, 2) in the reflection spectrum of Fig. 1 and uses this distance to calculate the blood oxygen content. This is possible because the distance between the minima (1 and 2) decreases with decreasing oxygen saturation until the minima merge into one minimum (3) in low-oxygen blood. <IMAGE>

Title: Ladder frame with attachment
Inventor: HAHN AXEL
IPC: E04G1/32
Filed: 1981-08-05
Abstract: Ladder frame with attachment, comprising two ladder legs which have a height of 130 cm and each comprise two ladder strings which are connected to each other by two or three rungs. The collapsing mechanism, and thus the connection of the two ladder legs, is achieved by a tube enclosing the uppermost rung of the other ladder leg. A chain welded on the respectively lowermost rung of each leg constitutes an optimum expansion-prevention means. The three-runged attachment having a height of 125 cm is easily attached by means of two hooks at the level of the fifth rung and two latching arms at the level of the third rung of the ladder frame. There are thus eight different bearing possibilities within the overall bearing height of 196 cm. On the bottom four stand ends of the ladder frame there is fitted in each case a metal plate which prevents sinking into a soft underlying surface. Advantages such as the possibility of extremely simple transportation, very low space requirement in the collapsed state and universal application possibilities owing to an eight-fold working height distinguish the uniqueness of this "ladder frame with attachment".
Patent DE-3131989-A1 (DE)
Inventor: FUCHS UWE ING GRAD
IPC: C02F3/12
Filed: 1981-08-13
Abstract: This invention relates to a process for the biological purification of wastewater in at least two immediately successive treatment stages, followed by a post clarification stage wherein the process is adapted so that a wastewater-activated sludge mixture in one of the treatment zones exhibits only a minor biological load and a nitrification process is conducted therein. In accordance with the invention, an intermediate clarification tank is not required due to substantially all biological degradation having occurred in the stage immediately before the nitrification stage. To enhance nitrification a macroporous carrier material for supporting nitrifying bacteria, for example, activated carbon or polyurethane foam, is added into this nitrification treatment stage. The material can be readily retained in the nitrification zone by providing appropriate retaining means. This process offers the advantage that the concentration of nitrifying agents, i.e., bacteria necessary for nitrification is maintained at the required level at all times. In another aspect, the invention relates to the apparatus for carrying out the process.

Title: Independently moving, self-guiding, multipole current collector for electric vehicles and devices
Inventor: WALDNER PAUL PROF DR ING
IPC: B60L5/40
Filed: 1981-09-15
Abstract: Independently moving, self-guiding, multipole current collector for electric vehicles and devices. The current collector contains a separate movement drive, is however movably connected to the current rail in a non-positively locking manner and can move along said rail under its own force. The connection between the current collector and electric vehicle or electric device is flexible and not provided for the transmission of mechanical forces. The guidance of the current collector along the current rail takes place by means of an appropriate control device consisting for example of an ultrasonic sound generator on the electric vehicle and two microphones from the collector. The arrangement operates by means of a running time comparison over the shortest possible distance between the current collector and electric vehicle or electric device. The travel rails can be configured to by multipoled, i.e. they can contain not only multiphase current for the power supply but also control signals. The power rails are of compact design (IP 13 protective system) and can also be easily laid.

Title: Hearing aid
Inventor: PASEMANN KARLO DIPL ING
IPC: H03G11/00
Filed: 1981-10-30
Abstract: A hearing aid normally contains a microphone, an amplifier, a volume control and an earpiece. To prevent unpleasant jumps and peaks in the volume level for persons with impaired hearing wearing such a device, automatic gain control (AGC) and peak cut-off (PC) are often provided by means of an amplification control circuit. Here, however, distortion of the transmitted amplified signal may occur. This is prevented according to the invention by feeding the signal from the microphone via a time delay to the amplifier while compensating for the control signal delay. A hearing aid according to the invention can be used in particular as an auditory prosthesis for persons with impaired hearing. <IMAGE>

Patent DE-3211261-A1 (DE)
Title: Oscillating piston machine
Inventor: HEUSCH GERHARD DIPL ING
IPC: F01B9/02
Filed: 1982-03-25
Abstract: The oscillating piston machine SKM essentially comprises two linearly moved pistons, each of which oscillates between two pressure chambers. Pistons and pressure chambers are so designed that a piston is never exposed to the pressures of opposing chambers at the same time. This is achieved in that one piston at its stroke mid-position lies outside both pressure chambers assigned to it, that is the chambers are pressureless in this piston position, so that undamped oscillation can occur. The two oscillating pistons move perpendicular to one another in separate planes and are connected to one another by way of a rotary connecting rod in the manner of a cardan drive; the crankpin, which with freely oscillating pistons performs an identical rotation about the system axis (= common normal of the two piston stroke paths), is carried by means of offsets on both sides of the connecting rod towards the axis of rotation located at the mid-point. The crucial innovation compared to earlier machines with cardan drive is the division of the piston strokes into two partial strokes of length 2r, so that the material forces in each pair of cylinders is proportional to the distance of the piston from its mid-position. As a result it is possible for the vector sum of the material forces to constantly equal the amount of a fully compressed cylinder and to rotate with the crank shaft. In this way the uniform rotation of the masses is supplemented by uniform rotation of the inertial forces and by uniform rotation of the gas forces counterbalancing or accelerating these.

Title: Cloth feeder
Inventor: GEHRKE ROLF
IPC: D05B27/02
Filed: 1982-05-18
Abstract: The invention relates to a cloth feeder for sewing machines, especially domestic sewing machines, which has tooth shapes optimum in terms of transport during sewing forwards and backwards. The cloth feeder according to the invention is produced from an elastic composite steel/plastic material by stamping and injection moulding. As a result of its constructive design, it acquires a permanent pretension which guarantees a plane-parallel bearing of the cloth feeder against the pressure foot and therefore a straight transport of the sewing material. Weight reductions of 50-60% in comparison with previous cloth-feeder designs moreover improve the vibration behaviour of the sewing machine.
