Title: Arf-p19, a novel regulator of the mammalian cell cycle
Inventor: SHERR CHARLES J
IPC: A01K67/027
Filed: 1996-09-25
Abstract: The INK4A (MTS1, CDKN2) gene encodes a specific inhibitor (InK4a-p16) of the cyclin D-dependent kinases CDK4 and CDK6. InK4a-p16 can block these kinase from phosphorylating the retinoblastoma protein (pRb), preventing exit from the G1 phase of the cell cycle. Deletions and mutations involving the gene encoding InK4a-p16, INK4A, occur frequently in cancer cells, implying that INK4a-p16, like pRb, suppresses tumor formulation. However, a completely unrelated protein (ARF-p19) arises in major part from an alternative reading frame of the mouse INK4A gene. Expression of an ARF-p19 cDNA (SEQ ID NO:1) in rodent fibroblasts induces both G1 and G2 phase arrest. Economical reutilization of protein coding sequences in this manner is without precedent in mammalian genomes, and the unitary inheritance of INK4a-p16 and ARF-p19 may reflect a dual requirement for both proteins in cell cycle control.

IPC: B29C48/694
Filed: 1996-12-02
Abstract: A device for filtering plasticised thermoplastics has a housing (1) with at least one supply channel (6) for the material to be filtered, via which said material is taken to the inlet side of at least one filter unit (3). The filtrate passes through fine holes (7) in the filter unit (3) and passes from its discharge side into at least one outlet channel (9) leading out of the housing (1). The inlet side of the filter element is scraped by the edges of doctor blades (11) moved in relation to said filter element (3), which guides the residues along the surface of the filter element (3) to at least one discharge channel (12). In the residue discharge direction the region (20) provided with holes (7) of the filter element adjoins an unperforated region (21) which is also scraped by the doctor blades (11). In the surface of the unperforated region (21) facing the doctor blades (11) there are grooves (29), the direction of which crosses that of the edges (24) of the doctor blades (11) extending over said grooves (29). The thickened compound on the unperforated region (21) is thus taken in concentrated form to the discharge channel (12).

Abstract: A goggle mounting system for retaining a pair of goggles to the lower edge of a helmet or the like. The goggle retention system comprises a plurality of clips, each clip having a base mounted to a helmet, and a removable eyelet shaped to receive and retain the goggles. Each base has an oblong slot extending therethrough and is shaped to receive and retain an associated eyelet. Each base further includes a pair of transverse locking notches and a helical camming surface extending between the slot and the notches. Each eyelet includes a generally circular ring to retain the goggle strap, and a pair of spaced, parallel legs extending from the ring. Each eyelet further includes a pair of opposed, spaced feet at the ends of the legs. The feet are shaped to pass through the slot when the feet are oriented lengthwise of the slot. An eyelet is attached to an associated base by passing the feet of the eyelet through the slot of the base and rotating the eyelet so that the narrowing width of the slot urges the legs closer together causing the legs to exert a reactive force against the inside walls of the slot, thereby securing the eyelet to the base, and securing the strap in the eyelet. The system of the present invention allows the goggles to be easily attached or released by simple hand manipulation.

Title: Minicell decoupling
Inventor: ENEROTH LARS GOERAN WILHELM
IPC: H04W80/00
Filed: 1997-05-16
Abstract: When using asynchronous transfer mode (ATM) in low bit rate applications, such as cellular voice communication, bandwidth utilization is significantly improved by employing decoupling minicells.  Decoupling minicells are of predetermined length, such as one octet, and are inserted into the payload of ATM cells when there is a delay in the availability of assigned minicells. As soon as an assigned minicell, which contains actual user data, becomes available, the assigned minicell can be inserted into the payload of the current ATM cell immediately after the last decoupling minicell. Unlike prior methods, there is no need to wait until the next ATM cell to insert an assigned minicell.
