Title: Smoke generator installed in car as theft deterrent - ignites smoke producing material when alarm is triggered
IPC: G08B15/02
Filed: 1984-09-21
Abstract: When a forced entry to the vehicle is made, a conventional intruder detection contact closes and, if the device has been armed, an electrical supply is connected to a filament embedded in the cartridge of smoke generating material- The ignited material emits smoke, which passes through a metal filter to emerge from the device, through a large number of holes in the cover. The metal filter is so fine that it acts as a flame trap, cooling the smoke as it passes through. The device is enclosed in a metal case with its perforated cover. The smoke generated quickly obscures the driving controls and anything else which the thief may wish to tamper with. The smoke, which is an irritant, though driving the thief out of the vehicle, is not toxic.

Title: Testing machine for pellets of animal foodstuffs - determines quality by measuring strength needed to shear through pellets
IPC: G01N3/24
Filed: 1985-09-11
Abstract: The pellets of feedstuff, which are cylindrical, are poured onto a vibrating disc (23) in the centre of a tray (24). The pellets (25) eventually move to the edge of the tray and pass over a narrow gap (26) onto a quasi-tangential chute (27). At the end of the chute, one end of the pellet enters one of the holes (12) in the circumference of a rotating disc (11). The disc carries each pellet to a fixed radial knife blade (18), which shears off the protruding end of the pellet. The pressure needed to shear the pellet is measured by a load cell pressure transducer (22). As the holes pass under the axis of the disc drive shaft, cam-driven plungers eject the remnants of the sheared pellets.

Title: Human macrophage migration inhibitory factor of nonlymphoid origin, expression of mif in e. coli and purification of recombinant protein
Inventor: MOZETIC-FRANCKY BOJANA
IPC: C12P21/00
Filed: 1994-09-19
Abstract: According to the known cDNA sequence we used the PCR (polymerase chain reaction) technique to isolate a gene encoding human MIF from uterus endometrium  The PCR product was cloned in the Escherichia coli plasmid vector pUC 19 and the nucleotide sequence was confirmed. We were able to successfully express human MIF in the bacteria Escherichia coli by use of the pKP 1500 expression plasmid. The recombinant protein accumulated intracellularly in soluble form, comprising more then 30 % of total cell protein. We have designed an original two step procedure where protein purification was accomplished by gel filtration and ion exchange chromatography. The purified recombinant MIF was used to immunise a rabbit and antibodies obtained were used for MIF detection in human tissues by immunohistochemical techniques.

Title: Mechanical method for realization of step (digital) translation and rotation
Inventor: KOSTOV YANKO
IPC: B64D35/00
Filed: 2016-05-31
Abstract: The invention relates to executive mechanisms generating digital translation along OY and rotation around OX. The components of the two groups `Mij toothed bar, Pij slider and Sij stand? are stationary fixed to each other, as they can slide along the slide loop `K?- in the direction of the OX and move it in the direction of OY. It is obvious that the number of the said groups ` Mij, Pij and Sij? must be 2 or greater than 2. The Gkl toothed bars and the RYm guides leading the slide loop along OY are stationary with each other and with the XOY. As a result of the application of external forces to the OX on Mij, the latter slide along this axis, as they are engaging / splitting off with/from their adjacent Gkl. The engagement of Mij with the fixed Gkl causes the digital linear motion of Mij and the slide loop `K? along OY. Shifting the direction of movement of the slide loop `K? is achieved by changing the sequence of the Mij's engagement with Gkl.
