Title: Motore a combustione interna a singola camma in testa
Inventor: SHIMIZU YASUHIRO
IPC: F01L1/12
Filed: 1995-09-06
Abstract: E' descritto un motore a singola camma in testa (ORC) in cui le valvole di aspirazione e di scarico e gli inseguitori della camma di aspirazine e di scarico sono disposti su lati opposti di una singola camma di azionamento della valvola che è prevista in una testata del cilindro. Le valvole di aspirazione e di scarico sono parallele una all'altra e perpendicolari ad un asse dell'albero a gomiti. Gli inseguitori delle camme di aspirazione e di scarico sono realizzati a forma biforcuta. Una porzione di braccio degli inseguitori delle camme di aspirazione e di scarico si estende verso l'interno, una verso l'altra, e vengono a contatto con le valvole di aspirazione e di scarico, e le altre porzioni di braccio degli inseguitori delle camme di aspirazione e di scarico si estendono anche essi verso l'interno, uno verso l'altro, e sono a contatto con una faccia della camma di azionamento delle valvole al disotto di un centro C di rotazione della camma di azionamento delle valvole. Con questo tipo di struttura, è possibile ridurre, sia per quanto riguarda le dimensioni che i costi, la testa del corpo del motore in un motore ORC.

Abstract: An air-sparged hydrocyclone apparatus and method, the apparatus including a substantially hollow, cyclone body having a cylindrical section and a downwardly oriented conical section. An inlet, an overflow and an underflow are also provided in the cyclone body. At least a portion of the wall of the cyclone body is modified to include an air-sparging section wherein air, under pressure, is forced into the interior of the cyclone body as a plurality of bubbles. The bubbles disrupt the boundary layer, freeing entrapped fine particles and also assist in carrying hydrophobic particles to the overflow. The introduction of discrete, small, air bubbles is enhanced by forming a portion of the wall of the cyclone body from a porous material.

Title: Drip-type dewatering endless belt, in particular a dewatering screen
Inventor: BEST WALTER
IPC: D21F1/00
Filed: 2000-03-07
Abstract: The continuous blanket (1) for a papermaking machine, where water is extracted from the pulp, is composed of a number of lateral plate-shaped bodies (2) linked together by flexible strands (9) which lie along the length of the belt (1). The strand ends are anchored in end pieces (5,6), which are coupled together to form the continuous blanket (1).  The end pieces are end bars (5,6), extending over the whole width of the blanket (1). The connecting strands (9) extend over the whole length of the blanket. Each flat body (2) has at least two connecting strands (9) through it. The bodies (2) are in lateral rows, offset against each other, so that the connecting strands pass through the offset bodies (2) in neighboring lateral rows. The bodies (2) have geometric shapes, fitting together as a jigsaw puzzle, as polygons and especially hexagons. They can also have a cross shape. The bodies can be flat rods, assembled to form lateral rows in the blanket with an offset so that the gaps in one row are bridged by the adjacent row. The bodies are strung loosely on the connecting strands, or they are bonded to them by adhesion or pressure. The bodies can have bending hinges, laterally across the blanket. The blanket end pieces (5,6) have eyelet passage channels to take a coupling wire (12) through them when they are in alignment. The end pieces (5,6) have passage openings where water can flow through. The end pieces and/or bodies form two complementary half-sections which are joined together, held by the connecting strands. Each half-section has half-channels on their facing sides to form passages for the connecting strands. The half-sections have couplings for an interlock, or they are bonded together by hot sealing or an adhesive.

Title: Brush
Inventor: TRENZ DIETHARD
IPC: A46B7/04
Filed: 2000-08-30
Abstract: The invention relates to a brush, especially a toilet brush, comprising a brush head and a brush head holder, wherein the brush head can be detachably mounted on the brush head holder, especially in such a way that the two interlock. According to the invention, the brush head can be slid onto the brush head holder with a friction fit. It is therefore possible to exchange a used brush head for a new, germ-free replacement. This not only avoids the unattractive appearance that conventional brushes acquire after repeated use, but also prevents health risks to the user.
