Abstract: A találmány egyrészt eljárás folyékony ragasztó csíkszerű felhordására, amelynek során a ragasztót felhordóedényen kiképzett kiömlő nyílásokon át ragasztandó felületre juttatjuk, miközben a felhordóedényt és a ragasztandó felületet egymáshoz képest elmozdítjuk és a kiömlő nyílásokon a ragasztó kiömlését szabályozzuk. Az eljárásban a ragasztó kiömlését a legalább egy sorban elhelyezett kiömlő nyílásokba illeszkedő tüskék betolásával és kihúzásával szabályozzuk, amely kiömlő nyílások közül felhordáskor a ragasztandó felület mindenkori helyzetének megfelelő kiömlő nyílások tüskéit kihúzzuk, a többi kiömlő nyílás tüskéit pedig betolva tartjuk. A találmány másrészt berendezés folyékony ragasztó csíkszerű felhordására, amely berendezésnek ragasztótarlálya, ehhez csatlakoztatott, kiömlő nyílásokkal ellátott felhordóedénye, ragasztandó anyagot felfogó szerve, valamint a ragasztandó anyagot és a felhordóedényt egymáshoz képest elmozdító mechanizmusa van. A találmány szerint a felhordóedény egyik falán kialakított kiömlő nyílásokba illeszkedő, hosszanti irányban elmozdíthatóan ágyazott tüskék vannak elhelyezve, amely tüskék a kiömlő nyílással ellentétes részükön mozgatószerkezettel vannak ellátva, és a felhordóedény említett egyik falával szemben lévő másik falában kialakított megvezetőnyílásokban vannak ágyazva.  lábra -1-

Title: Vegetable crop drying system - uses two-stage action, with predrying air warmed using waste heat from drying plant
IPC: A01F/
Filed: 1979-06-06
Granted: 1986-03-26
Abstract: A vegetable crop is dried in two stages, the predrying stage recovering waste heat from the main dryer. All available heat from the latter is consumed in the total drying operation, the predrying stage being effected using an air stream pased over layers of the vegetables. Air for the predrying stage is pref. heated by direct heat exchange with the exhaust gases of the dryer. Alternatively the preheating air can be warmed using a liq. as the heat carrier medium, the liq. being used to clean the exhaust gases.

Title: Segmented tyre mould - having segments actuating arrangement which relieves radial stress on the actuating links
IPC: B60C/
Filed: 1977-07-12
Granted: 1986-02-10
Abstract: A type mould comprises an inner matrix ring located between a pair of axial movable plates and an outer matrix ring formed by segments radially movable into contact with the inner ring. The segments are actuated by links themselves actuated by an operating ring rotatably mounted around the outer ring. Each segment carries a rearwardly directed projection which, when the ring is fully rotated and the segments moved into contact with the inner ring to form the mould cavity, engage cams carried by the ring. Each segment also carries a pair of forwardly directed projections which engage the edges of the plates when the segments are moved into contact with the inner ring. Contact of the rearwardly directed projections with the ring cams ensures that radial stress during moulding is absorbed by the ring and not by the actuating linkages and contact of the forwardly directed projections with the plates ensures that any axial stress is absorbed by the segments and is not transmitted to the plate supporting structure.

IPC: B21F11/00
Filed: 1999-05-17
Abstract: The invention pertains to the machines for straightening and cutting of wire on measured lengths. It can be used for manufacturing of rollers in chain production. The object of the invention is obtaining the geometrical accuracy of the blank to be cut and high quality of surface has been cut. Figure 1 represents a general view of the offered machine for cutting of rod material. It comprises a straightening unit (38), a feeding unit (40), a cutter tooling unit with knives (10), driving cams (22, 29, 30) and transmission devices connecting the cams (22, 29, 30) with tooling. Every device represents a hinged double-armed lever (24 and 32). One of the arms has a roller (23, 31) for the interaction with cams (22, 29, 30); the other one has a stop for interaction with tooling. The essence of the invention is the following: the cutters have the shape of semibushes. One of them is fixed rigidly on the tooling unit (10). The other three semibushes are mounted on sliders with possibility to move in guides. The semibushes interact mutually through the set of elastic elements mounted in pushers (35). Said elastic elements are set up also to ensure the possibility of clamping force adjustment. Besides the possibility of semibushes interacting with double-armed levers (24 and 32), the opposite ends of which are in contact with driving mechanism cams (22, 29 and 30), is ensured. The machine described above permits to achieve the object of the invention.

Abstract: Invention describes pharmaceutical delivery systems comprising 7-dimethyl-6-deoxy-6-demethyltetracycline and it salt which is formed during addition reaction with non-toxic acid. The smaller part of a mixture of substances in these delivery systems contains slowly releasable spherical granules coated by polymer mixture. These granules release part of minocycline in a medium with pH less than 3,9 and the remaining part in the medium with pH from about 4,0 to about 7,5. The largest part of the mixture of substances contains coated and uncoated fast releasing granules which can release minocycline in a medium with pH less than 3,9 as well as capsules containing one oral dose of minocycline. These delivery systems ensure high therapeutical level of minocycline in blood at least 24 hours when it is administered once a day. It is not important whether a patient abstains from food or is fed. Invention also describes methods for producing these delivery systems and compositions.
