Title: Use of intravenous contrast agents and devices for projection mammography
Inventor: ULRICH SPECK
IPC: A61B6/00
Filed: 1998-06-19
Abstract: The invention relates to the use of intravenous contrast agents for projection mammography and novel devices for carrying out projection mammography. The invention therefore relates to the use of intravenous contrast agents for producing a diagnostic medium for projection mammography. With the additional intravenous administration of contrast agent, projection mammography attains a sensitivity comparable to the most modern methods, such as magnetic resonance tomography (MRT) while having a wider range of applications and avoiding the cost of MRT. This novel method is simple and can be carried out without special inconvenience for the patients. It a) considerably improves sensitivity for demonstrating focal lesions in the mammae and b) provides additional information on the character of previously detected lesions.
Patent AT-A245288-A (AT)
Inventor: BECKMANN OTTO DR
IPC: B29C48/07
Filed: 1988-10-05
Abstract: With an injection arrangement designed according to the invention, high-grade profiles of uniform quality can be produced with comparatively low energy input and high output. The principle of the invention is that the injection material coming from a screw or a machine unit is at first taken further in tubular form in the injection head and, due to the special design of the injection head, is subsequently divided, then unrolled and passed on to the injection bar. <IMAGE>

Abstract: ABSTRACT OF THE DISCLOSURE:         A photoconductive member useful in a wet-type electro-graphic device is char?ed and radiated with a light image to pro-duce an electrostatic image.  Sensing electrodes automatically sense through a developing solution the remaining potential in a portion of the electrostatic image corresponding to a background area of the original document scanned to produce the light image.          In one embodiment the area is a white reference document disposed adjacent to the original document.  In another embodiment a refe-rence document is not provided and a plurality of portions of the electrostatic image are sensed.  The lowest value of the sensed potential is utilized.  Computing circuits compute and apply the biasing voltage to the developing electrode as a predetermined function of the sensed potential.

Abstract: ABSTRACT OF THE DISCLOSURE          There is provided a slide fastener having a pair of oppositely disposed carrier tapes each carrying on and along one longitudinal beaded edge a series of discrete fastener elements made of metal.  The fastener elements are each provided with a coupling head and a pair of legs extending from the coupling head and having oppositely disposed inner wall portions.   here are formed a plurality of teeth integral with the element legs and projecting from the oppositely disposed inner wall portions such that a first one of said legs comprises two of said teeth, the second one of said legs comprising one of said teeth.  The teeth are smaller in thickness than the element legs as measured along the longitudinal direction of the beaded edge.         Each of the teeth on one leg is staggered relative to a corresponding tooth on the other leg as measured along the longitudinal direction.  The teeth are disposed in gripping engagement with the beaded edge to secure the elements to same.  The advance in the art is in an improved stability of the discrete fastener elements on and around the longitudinal beaded edge of a carrier tape.  The invention thus provides an improved slide fastener wherein discreet fastener elements are more firmly mounted in position on and around the longitudinal beaded edge of a carrier tape.

Abstract: AUTOMATIC SPRAY CLEANING   APPARATUS AND METHOD     Abstract An automatic high pressure spray cleaning appa-ratus and method for rapidly and efficiently removing material coated on the surface of an object are described.          In accordance with the invention the axis of the cleaning liquid spray forms an acute angle with the object surface and such angle, as well as the distance along such axis between the spray nozzle and the object surface, are both maintained substantially constant over a given surface area.  In addition, the pressure of the cleaning liquid at the surface of the object is also maintained substan-tially constant over such given area.  The spray nozzles are automatically moved over the object surface along a predetermined path while maintaining the spacing distance and angle substantially constant by motor operated drive means which may be controlled by an electronic computer.          The cleaning apparatus is especially useful for cleaning the interior surface of container tanks, such as chemical reactor tanks which contain internal baffles and other obstructions.  The nozzles are mounted on folding support arms which are supported on a vertical shaft to fold such arms in and out relative to the axis of such shaft.  In addition, the support shaft rotates the nozzles through a predetermined horizontal arc and also raises and lowers the cleaning apparatus.  The cleaning apparatus is supported on a mobile derrick for movement of such appa-ratus along guide rails between a plurality of container tanks.  The reactive forces produced by the liquid spray on the spray nozzles are balanced so that the total bending force exerted on the vertical shaft is kept at a minimum regardless of the position of the folding support arms carrying such nozzles.

Abstract: ABSTRACT OF THE DISCLOSURE                  The present invention is for a process for producing aluminum by electrolyzing aluminum oxide dissolved in a molten salt bath in an electrolytic cell using ? Soderberg anode. The anode has vertical contact studs which are removable from the anode paste in the cell. The paste is composed of a composition that does not form a liquid or soup-like layer during electro-lysis. Instead, the process forms three layers, an upper layer, an inter layer and a lower layer. The lower layer is baked by heat from the molten salt bath and the joule heat generated from the contact portion between the contact studs and the anode paste. The interlayer is unbaked and is sufficiently viscous so as to retain its shape so that it will not flow into the holes formed should the studs be removed. The upper layer com-prises layer of small molded forms of the anode paste. There is a sufficient amount of such forms so that a load of at least 5 g/cm2 per unit area on the interlayer therebeneath is achieved. The surface temperature of the upper layer is no more than about I30°C.
