Abstract: The invention relates to a cleaning method and device for the inner surface of an elongated hollow body (1) which has been contaminated with particles and in which a free jet of a fluid under pressure emerging from a nozzle (12) is directed onto an open end of the hollow body (1) and entrained particles leave the hollow body (1) at the other end. In order to permit complete cleaning of the inner surface of the hollow body (1) and controlled removal of the dirt particles with a fully automatic method of operation without giving rise to noise and dust pollution it is proposed that the jet of liquid be directed onto the inner surface of a hollow body (1), which is inclined during the rinsing process in the longitudinal direction, in the form of a circulating movement, the radius of the circular movement being continuously changed during the rinsing process and the distance of the exit point of the jet from the open end of the hollow body (1) being adjusted to a predetermined distance and the liquid collecting on the base of the hollow body (1) running out of the hollow body (1) together with the particles at the end opposite to the jet side and being led off in a directed fashion and liquid and particles being subsequently separated from one another and the clean liquid being fed back to the jet side.

Abstract: A global mapping system which organizes mapping data into a hierarchy of successive magnitudes or levels for presentation of the mapping data with variable resolution, starting from a first or highest magnitude with lowest resolution and progressing to a last or lowest magnitude with highest resolution. The idea of this hierarchical structure can be likened to a pyramid with fewer stones or "tiles" at the top, and where each successive descending horizontal level or magnitude contains four times as many "tiles" as the level or magnitude directly above it. The top or first level of the pyramid contains 4 tiles, the second level contains 16 tiles, the third contains 64 tiles and so on, such that the base of a 16 magnitude or level pyramid would contain 4 to the 16th power or 4,294,967,296 tiles. This total includes "hyperspace" which is later clipped or ignored. Digital data corresponding to each of the separate data base tiles is stored in the database under a unique filename,

Abstract: A liposome composition for localizing an anti-tumor compound to a solid tumor via the bloodstream. The liposomes, which contain the agent in entrapped form, are composed of vesicle-forming lipids and between 1-20 mole percent of a vesicle-forming lipid derivatized with hydrophilic biocompatible polymer, and have sizes in a selected size range between 0.07 and 0.12 microns. After intravenous administration, the liposomes are taken up by the tumor within 24-48 hours, for site-specific release of entrapped compound into the tumor. In one composition for use in treating a solid tumor, the compound is an anthracycline antibiotic drug which is entrapped in the liposomes at a concentration of greater than about 50  mu g agent/ mu mole liposome lipid. The method results in regression of solid colon and breast carcinomas which are refractory to anthracycline antibiotic drugs administered in free form or entrapped in conventional liposomes.

Abstract: To improve the illumination time of a switchless orientation aid for the location of a keyhole, especially on a motor-vehicle lock, with at least one light-radiating surface element (6) which is so arranged in the immediate vicinity of the keyhole that it gives a visual indication of the position of the keyhole, it is proposed to equip at least one surface element (6) with a number of low-current luminous diodes (12) connected electrically in series and to connect these permanently to a low-voltage source (U), especially to a motor- vehicle battery, the current consumption of the luminous diodes (12) being limited by a current limiter to a value well below their lowest specified working current. Advantageously, the total voltage drop across the current limiter and the low-current luminous diodes (12) can be of such a size that, when the supply voltage falls below a specific critical value, these fall below the saturation voltage and, without further measures, become highly resistine. <IMAGE>

Title: Infrared intrusion detector
Inventor: STEINER PETER
IPC: G08B29/04
Filed: 1991-08-30
Abstract: In a passive infrared intrusion detector, which evaluates the body radiation of an intruder with the aid of a dual sensor (3) having two sensor elements (8, 9) in a differential circuit in order to give an alarm signal, an attempt to put the detector out of action by covering or spraying the radiation entry window (2) is detected and signalled by a monitoring beam path from an infrared radiation source (7) through the window (2) via a further optical system (6) to the sensor (3). In order to achieve a different irradiation of the two sensor elements (8, 9), this optical system (6) generates at the site of the sensor (3) irradiation having an intensity which decreases gradually to the sides. If the sensor elements (8, 9) are located laterally offset on the decreasing edges of the irradiation curve, their irradiation differs without the need for a precise adjustment. This can be achieved, for example, by forming aspherical mirrors, or as segmented mirrors (6.1, 6.2, ..., 6.5), which form at the sensor site overlapping irradiation spots (B1, B2, ..., B5) which overall have a stepped intensity curve. If the step width is not larger than the spacing (ds) of the sensor elements (8, 9), the two sensor elements (8, 9) necessarily receive a different irradiation. <IMAGE>
