摘要： The material compactor (10) generally includes a feed apparatus (12) and a final compaction apparatus (16). The final compaction apparatus (16) generally includes a compaction chamber (32) having confronting compression plates (44, 46) and an adjustably taperable portion (54). The area of the inner cavity (54) of the final compaction chamber can be adjusted to become measurably smaller (tapered) or larger at the opened discharge or expelling end (58). Consequently, compacting movement of the material within the compaction chamber and through the chamber significantly subjects the material to restrictive compacting pressure which in turn compacts the material and performs liquid separation with each operationally continuous movement through the final compaction apparatus and out an open discharge port (58).

摘要： A device (110, 160) for holding a workpiece or part (136) in a desired position against a stop (188, 140) on a platen (116). The device (110, 160) includes a threaded shank actuator (112, 150, 162) and a sliding clamping member (114). The actuator (112, 150, 162) has a tapered head which engages an inner bearing surface (122) of the sliding clamping member (114) to simultaneously apply clamping forces against the workpiece (136) and securing forces to anchor the sliding clamp member (114) to the platen (116). A spring element (117, 121) joined to the clamping member (114) retracts the clamping member (114) away from the workpiece.

摘要： A vise (10) has a fixed jaw (14) mounted stationary relative to a vise body (11). A movable jaw (20) is supported on side rails (18) that have upper way surfaces (18A). A jaw nut (24) that exerts a downward force on the movable jaw (20) is operated to move the movable jaw (20) along the way surfaces (18A). A resilient member (44,48; 82,83) is provided between the under side of the movable jaw (20) and at least one of the way surfaces (18A) to space the movable jaw (20) slightly from the way surfaces (18A) until the movable jaw (20) engages a workpiece (40) at which time the resilient material (44,48; 82,83) compresses and provides a positive hold down force on the workpiece (40).

摘要： A work stop (56) for use on a machine vise (10) is received in a jaw plate (20,22) for such vise (10) and is securely locked in position. The work stop (56) is fixed in a groove (58) that is machined int a top edge of the jaw plate (20,22) or jaw, with a member (57) extending over the edge of the jaw plate (20,22) and adjacent the face of the jaw plate (20,22) that is used for clamping a workpiece. This permits the workpiece to be slid against the stop (56) before being clamped. The jaw plate (20,22) is removable mounted onto a fixed jaw (18) and is located precisely relative to the fixed jaw (18) so that the jaw plate (20,22) with the work stop (56) attached an be removed, and then replaced when the same part is to be machined again.

摘要： A gas bearing (10) designed for instantaneous 5-10 micro inch separation at startup due to regulated entry and activation of rarefied molecular gas particles. The bearing has two opposing bearing faces (13, 21) with carefully matched geometries. One surface having grooves (15) with lands (16) formed between the grooves (15) that are designed for hydrodynamic operation. The other surface (21) is smooth such as an optically flat plane. The lift-off occurs at startup through the friction-energized gas molecules increasing their volume, and forcing the slowly rotating bearing faces apart. A precisely contoured leading edge (17A) is formed on each land (16) which sustains a negative molecular gas pressure in the slowly moving bearing interface, so as not to cause any unwarranted cooling or compression of the gas molecules until such speed is reached so that the normal pressurized gas bearing lift-off has been achieved, causing the gas compression flow to become unregulated and go normal.

摘要： Le palier à gaz (10) est conçu pour assurer une séparation instantannée de l'ordre de 5 à 10 micropouces au démarrage grâce à une entrée et activation régulées de particules de gaz moléculaire raréfié. Le palier possède deux faces opposées (13, 21) ayant des géométries correspondant précisément. Une surface possède des rainures (15) ayant des plats (16) formés entre les rainures (15) et destinées à fonctionnement hydrodynamique. L'autre surface (21) est lisse telle qu'un plan optiquement plat. Le décollage ou la levée s'effectue au moment du démarrage par l'intermédiaire de molécules de gaz excitées par friction qui augmentent de volume et obligent les faces du palier en rotation lente à se séparer. Un bord d'attaque à profil précis (17A) est formé sur chaque plat (16) qui supporte une pression de gaz moléculaire négative dans l'interface de palier à faible déplacement de manière à ne pas provoquer un refroidissemnt ou une compression injustifiée des molécules de gaz jusqu'à atteindre une vitesse correspondant au décollage du palier à gaz pressurisé normal, formant un écoulement de gaz comprimé non reglé et normal.

摘要： The material compactor (10) generally includes a feed apparatus (12), a preliminary compaction apparatus (14), and a final compaction apparatus (16). The final compaction apparatus generally includes a compaction chamber (52) having an adjustably taperable choke tube (34). The area of the inner cavity (53) of the final compaction chamber can be tapered to become measurably smaller or larger at the discharge or expelling end. Consequently, compacting movement of the material within the compaction chamber and through the tapered choke tube significantly subjects the material to restrictive compacting pressure which in turn compacts the material and performs liquid separation with each operationally continuous movement through the final compaction apparatus.

摘要： A removable quick change jaw plate (38) for a vise (10) has a T-slot that receives a pull rod that extends into a bore formed in the vise jaw (26, 28). The pull rod is actuated to pull the jaw plate (38) toward the vise (10). A wedge clamp, actuated by a threaded element provides a clamping motion to hold the jaw plate (38) on the vise (10).

摘要： Un étau (10) de machines à utilisations multiples comprend une base coulée (11) aisément montable à des fins d'usinage à commande numérique ou est monté sur une base pivotable (150), sur ses côtés ou sur une extrémité. Afin de simplifier le serrage sur une table d'outils, l'étau comprend un rebord accessible (35, 36, 37) de serrage le long de ses côtés et de ses extrémités qui forme également une rigole de drainage (40) du liquide de refroidissement. Un support (85) de l'extrémité distale de la vis (53) de l'étau simplifie la fabrication de l'étau sans en réduire la précision de fonctionnement. La même base (11) d'étau peut être adaptée afin d'être utilisée avec des vis interchangeables d'actionnement manuel d'une mâchoire mobile (12) depuis l'une ou l'autre extrémité de l'étau ou avec un mécanisme hydraulique d'actionnement (120) qui sert à serrer la mâchoire mobile.
