Title: Method for producing a continuous panoramic radiograph in a set of separate exposure sequences
Inventor: KANERVA HEIKKI K J
IPC: A61B6/14
Filed: 1990-01-15
Abstract: A panoramic method for the radiography of the dental arch and jaws, in which method by means of movable radiographing and/or imaged elements, several subsequent exposure sweep sequences are performed so that the moving elements are transferred to a new position between the subsequent exposure sequences. In order to achieve a perfectly jointed X-ray picture, the movement of the moving elements is started before the switch-on instant of the X-ray beam in the latter exposure sequence and the starting positions of said elements is selected so as to obtain desired positions and velocities for the elements at the switch-on instant of the X-ray beam. The coincidence of the X ray beam orientation at the start of the latter exposure sequence with the X-ray beam orientation at the end of the preceding sequence is characterizing to an embodiment of the invention.

Title: Process for the complete reprocessing of high polymer waste products
Inventor: DUMMERSDORF HANS-ULRICH
IPC: C07C4/04
Filed: 1990-08-30
Abstract: ABSTRACT OF THE DISCLOSURE          High polymer waste products fill the garbage dumping grounds or they are only insufficiently converted into new low-quality products by means of imperfect recycling processes.  The novel process according to the present invention will make it possible to process high polymer, preferably those which contain no volatile matter that can be defined by standardized measuring methods independently of their chemical composition and physical consistency in a form such that the raw material substance contained therein is completely reusable.            The polymer waste products are converted into a crushed or granulated form and into a conveyable consistency by mixing them with superheated steam and by feeding them to a hydrogen plasma jet having an average mass temperature of at least 1000°C and a pressure of 0.05 to 0.5 MPa so that the polymer suspension or granulate is mixed with the hydrogen plasma.            In this hydrogen plasma the polymer waste products are completely decomposed and are reacted to highly endothermic valuable target products, such as acetylene, ethylene, hydrogen, CO, HCN or HCl.            The aim is the complete material reprocessing and high finish of all the high polymers made available by the chemical industry, i.e., those having passed through one or several utilization processes.

Patent CA-2029837-A1 (CA)
Inventor: BEERMAN JOHANNES H M
IPC: G06V30/10
Filed: 1990-11-13
Abstract: The invention comprises a buffer system and a buffer (20) applied in it. The buffer acts as mechanical RAM and contains a number of storage pockets (28) for the temporary separate storage of flat articles such as letters for postal processing purposes such as, for example, sorting and video coding. Electromechanically the buffer is such that the letters are not released at any point and are subject to shifting as little as possible, and permit a dense packing of the pockets. This is achieved by using a slide/entrainment conveyance system which is formed by elastic clamping between an endless conveyor (54, 72, 77) with a very high coefficient of friction, for example one or more elastic cords running in parallel and a sliding surface (60, 73, 75) having a very low coefficient of friction both in the sections (21 and 22) of conveyance past the pockets and in the pockets (28). In the pockets, said sliding/entrainment conveyance system is constructed as a separately controllable letter catchment, retainment and ejection device. Each two successive buffer pockets have a partition in common provided with the endless conveyor (54) of one of the said two pockets and the sliding surface (60) of the other of the said two pockets. The buffer system comprises a number of such buffers (20) with or without distributed control. The buffers (20) are situated along a branching feed section (1, 23) in which a gate (20, 26) is sited at every buffer branching point and every connecting point. First process signal connections (6) via which so-called letter logging signals (BBS) are concomitantly transmitted for every letter conveyed along the feed section (1, 23) run in parallel with the branched feed section. Appended to each of said gates (25, 26) is a gate control (91, 38) which determines on the basis of the letter logging signals (BBS) and, for example, the number of free pockets (#-VAKKEN) in each of two gate directions in which direction the letter with its associated letter logging signals (BBS) is sent. Said letter logging signals comprise in all cases a letter identification code (BIC) assigned to the letter by an application control (5) when the letter is fed into the system. The application control continuously makes a selection of letters, which are eligible for discharge from the system, from the instantaneously stored letters on the basis of certain letter features which are derived from the letters to be fed in at the system entrance. Data of the selected letters, including time indications (TI) of when the letters have to pass a defined ejection point (X) in the system exit are transmitted via second process signal connections (9) to the control (38) of each of the buffers (20). Such a buffer system can readily be equipped either as a sorting system or as a video coding system.

Title: Method and apparatus for detecting liquid leaks
Inventor: JENSEN JAY E
IPC: G01F23/18
Filed: 1990-01-12
Abstract: A liquid leak detector for above-ground tanks includes an upright standpipe connected to the tank so that the standpipe can be filled with liquid from the tank to the same level as the liquid in the tank. A pressure transducer is connected between the bottom of the tank and the bottom of the standpipe to measure the difference in pressure of the liiquids in the tank and standpipe. Any change in the liquid pressure at the bottom of the tank as a result of leakage from the tank will change the pressure differential on the pressure transducer. This changes the output of the transducer which can be recorded to indicate leakage from the tank.
