Patent DE-3127146-A1 (DE)
Title: Method for correcting image errors (aberrations) caused by echo-time effects in the ultrasonic scanning of objects, in particular in ultrasonic reflection computer tomography and in the compound-B scanning method
Inventor: HUNDT ECKHARDT DR
IPC: A61B8/14
Filed: 1981-07-09
Abstract: In conventional ultrasonic scanning, the object is scanned by means of a multiplicity of echo sequences. For this purpose, the transmitter/receiver is displaced at right angles to the direction of irradiation. An echo sequence is recorded from each position and - as previously described - converted into the object region. These echo sequences are then assembled in a manner known per se in accordance with the position of the transmitter/receiver to form a two-dimensional split image. The differences in sound velocity inside the object and in the medium surrounding the latter lead to distortions in scale. This can give rise to losses of definition (un- sharpness) and image errors, which cause difficulty in diagnosis or can even cause a wrong diagnosis. The object of the present invention is to provide a method for correcting echo-time effects which are the cause of the disadvantages to be explained, thus permitting objects which have variable sound velocities, in particular of biological tissue, to be imaged largely free from distortion. A method is proposed for achieving this object, which is characterised in that partially differing sound velocities are adopted for the purpose of reconstructing the image of the relevant object region from the ultrasonic signals.

Title: Method for adjusting the orbit of a three-axis-stabilised satellite
Inventor: GOESCHEL WILHELM DIPL PHYS
IPC: B64G1/24
Filed: 1982-04-20
Abstract: A method is described for adjusting the orbit (3) of a satellite (2, 2a) which is equipped with thrust nozzles (12), it being possible to use the thrust nozzles (12) for orbit and orientation control. After separation of the satellite (2, 2a) from its carrier vehicle, the yaw axis (5) is aligned to the centre of the earth and the satellite is caused to spin about this axis. This takes place at a point which is located on the perpendicular (11) to the apsis line (10) between the perigee and the apogee. When the satellite (2, 2a) intersects the apsis line, the thrust nozzles (12) are activated. The necessary orbit calculations are carried out by a ground station. <IMAGE>

Title: Method for optical time division multiplex transmission via an optical waveguide of a switching system, in particular a telephone switching system
Inventor: WIEDEBURG KLAUS-H DR
IPC: H04Q11/04
Filed: 1982-06-11
Abstract: Method for optical time division multiplex transmission via an optical waveguide of a switching system. Between system devices capable of transmission and/or reception which are connected to the optical waveguide, transmission of control signals, which set such light systems, and of subscriber information is provided. In the pulse frame defined by frame identification signals, a first block of time slots serves to transmit the control signals and a second block of time slots serves to transmit the subscriber information. Each transmission-capable system device contains a counter or clock in order to allocate a transmission time slot to the transmission-capable system device concerned. The transmitting system device occupies the system device designated to receive the subscriber information by transmitting the address of this system device in the transmission time slot, where this designated system device is set, e.g. is switched to a different switching state. The frame identification signal (RK1, RK2) contains short light flashes whose intensity is significantly greater than the maximum intensity of the subscriber information and the control signals, the light flash in each case resetting the counter or clock in the system devices to its initial state. <IMAGE>

Title: Displacement machine for compressible media

IPC: F04C29/00
Filed: 1982-11-25
Abstract: A displacement machine for compressible media has at least one displacement chamber arranged in a fixed housing and designed in the form of a spiral slot, and a strip or tongue-like displacement element, likewise spiral in form, assigned to this displacement chamber, this displacement element being held on a disc-shaped rotor which can be driven eccentrically in relation to the housing in such a way that during operation each of its points performs a motion essentially lying on a circular path and defined by the peripheral walls of the displacement chamber, and the curvature of which in relation to that of the displacement chamber is so dimensioned that it virtually touches the inner and outer peripheral walls of the displacement chamber, in each case on at least one sealing line continuously progressing in the peripheral direction during operation. At the same time lunate working chambers are formed between the peripheral walls of the displacement chamber and the displacement element, which chambers are shifted from an inlet to an outlet with reduction of the internally enclosed volume. In order to be able to continuously reduce the delivery of a displacement machine of this type whilst the drive speed remains constant, the eccentricity of the rotor drive is to be continuously variable between the value 0 and a maximum value.

Title: Oxygen and fat as alternative fuel for conventionally known internal combustion engines, and associated, not very expensive modifications of existing internal combustion engines
Inventor: REICHELT WILHELM
IPC: F02B45/10
Filed: 1982-11-23
Abstract: Oxygen and fat in the liquid form as alternative fuels for four-stroke internal combustion engines of the diesel system and spark-ignition system. Oxygen present in the atmosphere is obtained by fractional distillation of liquefied air. Highly compressed and heated oxygen has the property of exploding when it comes into contact with fats. At the point in time of the highest compression and heating to 500 to 700 degrees, liquid fat is injected in the smallest possible dosage into the combustion chamber. Combustion takes place. The fats can be of vegetable, animal or mineral origin. These are collective terms. Vegetable fats are linseed oil, rape oil, soya oil, sunflower oil and others, animal fats = any animal, and mineral fats can originate from bituminous coal or petroleum. In a manner of speaking as a "troika" with the motor vehicle industry and the motor vehicle workshops, agriculture, fighting hard for its existence, would reap not inconsiderable benefits. Plant cultivation and animal rearing for this purpose would lift agriculture out of the depression. An alternative fuel on this basis is completely non-polluting and therefore harmless to health.

Patent DE-3327633-A1 (DE)
Title: Yarn-braking device
Inventor: WILDI EDWIN
IPC: B65H59/16
Filed: 1983-07-30
Abstract: Two rollers (10, 18) are mounted freely rotatably in an axis-parallel manner in a housing (3) and limit between them a nip (28), through which the yarn to be braked is drawn. One roller (10) is mounted at a fixed location in the housing (3). The other roller (18) has a covering (19) made of elastomeric material. It is mounted in a pivotable fork (13) and can be pressed with adjustable prestress against the roller (10) of fixed location by a spring-loaded angle lever (23) acting the on the fork (13). A sleeve-shaped yarn-guide carrier (30) projects through a slot (31) in the housing (3) into the region of the nip (28). This yarn-guide carrier (30) is connected via a releasable lock to an arm (34) which is fastened to a lifting rod (35). A to-and-fro movement in the axial direction of the nip (28) is imparted to the lifing rod (35) and, via this, to the yarn-guide carrier (30), with the result that the passage point of the yarn through the nip (28) changes constantly. <IMAGE>
