Patent CZ-201223-A3 (CZ)
Inventor: AGEL PETR
IPC: E04G23/02
Filed: 2012-01-13
Abstract: Sanace dreveného prvku (1), který je umísten v historické budove, je provádena tak, ze drevený prvek (1) je vyjmut z místa svého ulození ve stavbe a následne osetren proti drevokaznému hmyzu. Poté je do dreveného prvku (1) vyfrézována drázka (3) o velikosti a tvaru poskození. Do takto vzniklé drázky (3) je naneseno lepidlo a vlozeno výztuzné jádro (2), které je upnuto stolarskými sverkami. Výztuzné jádro (2) je provedeno ze zdravého dreva, které má stejné vlhkostní parametry jako sanovaný drevený prvek (1). Po zaschnutí lepené spáry (4) vzniklé mezi sanovaným dreveným prvkem (1) a výztuzným jádrem (2) je proveden historizující náter. Poté je drevený prvek (1) vrácen na své puvodní místo ulození ve stavbe.
Patent CZ-214793-A3 (CZ)
Title: Device preventing backward motion of a nut on a threaded piston provided within a cylinder of hypodermic syringe in the end of the dose
Inventor: HARRIS DALE CARVIN
IPC: A61M5/315
Filed: 1993-10-12
Abstract: The present invention provides an anti-backup device which prevents the nut (10) from moving up the threaded piston (5) at the end of the dose by rotating in the opposite direction of that in which the nut (10) moves up the position to set the new dose by rotating dose knob. In this way, it is assured that movement of the nut up the threaded piston is due to rotating the dose knob (15) in the proper direction. The preferred device is a pawl (25) mounted on the end of a flexible arm (32) of the nut which cooperates with slots (26) on the inside of the syringe barrel (27). The nut (10) also has an incline surface (28) at the end which mates with an incline surface (29) in the barrel (27) and the mating of these surfaces at the end of the dose forces the pawl (25) into a slot (26) and prevents rotation of the nut (10) in the wrong direction, thus preventing refilling of the syringe. <IMAGE>
