Patent HR-P20100683-B1 (HR)
Inventor: BRKIĆ BLAGO
IPC: F16S3/00
Filed: 2010-12-09
Abstract: š titnik od padalina prema slikama 1, 2, 3, 4 i 5 omogućava odvod tekućine koja upada u otvore za zrak između dva savijena izdanka (1a) usisne rešetke (1) i pod vrlo nepovoljnim kutem mlaza (m), kao na primjeru sa slike 11. Slika 1 prikazuje pogled na štitnik iz smjera koji je okomit na ravninu otvora (5). Lijeva polovina slike 1 prikazuje izgled toga pogleda kad je montirana usisna rešetka (1), a desna polovina kad nije montirana usisna rešetka (1). Slika 2 predstavlja pogled C sa slike 1, to jest na gornji uzdužni lim (2c) okvira (2). Uzdužni lim (2c) nema otvore tamo gdje se u okviru (2) nalaze poprečni kanali (2b), pa su ti kanali nacrtani crtkanim linijama, jer se ne vide. Slika 3 predstavlja pogled B sa slike 1, to jest na donji uzdužni lim (2d) okvira (2). Uzdužni lim (2d) ima otvore (2d1) tamo gdje se u okviru (2) nalaze poprečni kanali (2b), pa su ti kanali i otvori (2d1) na limu (2d) nacrtani punim linijama, jer se vide. Slika 4 predstavlja presjek A-A sa slike 2, to jest na dijelu štitnika između dva susjedna poprečna kanala (2b) okvira (2). š titnik se sastoji od jedne usisne rešetke (1) i jednog podsklopa, naziva okvir (2). Usisna rešetka (1) je lim u kojem okvirni dio, kao prirubnica (1c) i više držača (1b) savijenih izdanaka (1a) ostaju u ravnini lima, a između svaka dva susjedna držača (1b) se laserski isječe lim, tako da omogući savijanje izdanaka (1a). Razmaci između savijenih izdanaka (1a) služe za usis zraka, ali kroz njih upadaju i padaline u obliku mlaza (m), čije su karakteristične strujnice (s1, s2, s3, s4 i s5) za projektno zadani kut upada (α) u odnosu na horizontalnu ravninu (h). Ako navedene strujnice zaustavi nekoliko redova kutni ka (2a), gravitacijske i inercijske sile, zbog vožnje u smjeru (SV1 ili SV2), omogućuju istjecanje tekućine kroz uzdužne kanale (3a i 3) između krakova kutnika (2a) te izljev kroz otvore (2a1) u poprečni kanal (2b), a onda kroz otvore (2d1) na uzdužnom limu (2d).

Title: Separable fastener and method and apparatus for producing same
Inventor: FISCHER JAMES R
IPC: B29C48/00
Filed: 1986-06-26
Granted: 1991-07-23
Abstract: Apparatus for continuously producing an elongated strip-like fastener member is disclosed which facilitates highly efficient formation of the fastener member with a great multiplicity of resiliently flexible hook-like projections. The method comprises the formation of an extrusion of plastic material which is shaped between a pair of coacting first and second rollers of the apparatus. Notably, one of the rollers is formed of a series of plates and defines a plurality of hook-forming cavities about its periphery within which the hook projections of the fastener member are formed. The forming roller is suitably cooled so as to effect substantial reduction in the temperature of the molten plastic extrusion form which the fastener member is formed. In this manner, the fastener member may be removed or stripped from the forming roller without opening of the hook-forming cavities, thus promoting highly efficient formation of the fastener member without resort to unduly complex equipment or processes. The fastener is uniquely configured and includes upstanding hook-like engaging elements having stem portions of at least partially arcuate configuration to produce a combination of properties previously unknown in such fasteners.
