Abstract: A process is provided for the preparation of 3-methylene and 3-halomethylene cepham derivatives via 3-phosphoniomethyl-3-cephem derivatives, which in turn can be prepared from 3-halomethyl-3-cephem derivatives. The preparation can be carried out with or without isolating the intermediate phosphonium cephem compounds. The 3-methylene and 3-halomethylene cepham derivatives and in particular the 1-oxo and 1,1-dioxo cepham compounds are also prepared by reducing a 3-halomethyl-3-cephem derivative with activated metal, preferably zinc or magnesium.

Title: Rotary piston compressed air motor
IPC: F01C13/02
Filed: 1988-11-19
Granted: 1992-01-29
Abstract: A rotary piston compressed air motor has a housing (1) in which is lodged a rotor (3) whose drive shaft (44, 45) emerges from the housing through a passage (48) protected from explosions in order to drive any type of unit, for example a pump. The gap (50) between the drive shaft (44, 45) and the passage (48) in the housing is designed to preclude the emergence of ignition sparks. The motor housing (1) has a pressure-proof protection. An ignition spark barrier (28) made of sintered metal is arranged in the compressed air suppy line (7) and in the exhaust air line (37). All the threaded connections (23, 27) for fastening the ignition spark barriers (28), both in the compressed air supply line (7) and in the exhaust air line (37), prevent the passage of ignition sparks. The same applies to the threaded connections (49) between the passage (48) in the housing (1) and the part (2) of the housing (1), the threaded connection (39) between the exhaust air line (37) and the shoulder (38) of the part (2) of the housing, and the threaded connection (10) between the valve (8) and the housing bore (9).

Abstract: A cutter plate is provided for precision working, especially of holes, which is constructed as a symmetrical polygon with at least four corners and has at least one main cutting edge and one auxiliary cutting edge, as well as a projection which begins at the chip run-off surface of the cutting edges, whose sides serve as chip-guiding steps and whose boundary lines circumscribe a symmetrical polygon, whose shape corresponds to that of the cutter plate, and has smaller dimensions than the latter, so that, starting from the corner regions of the polygon, the width of the chip run-off surfaces decreases. The cutter plate is distinguished by the fact that each chip run-off surface has a plane shape and is inclined in the direction of its longitudinal extension by an angle in such a way that the narrowest region is at the greatest height and is arranged to be above the neighboring chip run-off surface, so that it can be manufactured very simply and economically by a grinding procedure. In this way, a very high accuracy of dimensions can be achieved. With this cutter plate, an optimum flow of chips and hence a superior surface quality, can be achieved. The shape of the cutter plate is so simple that several different cutter plates can be manufactured easily at favorable cost for various application purposes.

Abstract: The refractory stator/rotor unit for a nozzle gate of a vessel (11) containing molten metal consists of a stator (15) fastened in the vessel wall (14), and of a rotor (16), which is rotatable in the latter from the underside (11') of the base of the vessel and serves for opening or closing the gate. The unit projecting into the vessel has transverse openings (17, 18) extending therein and, starting from these openings (17, 18), a nozzle opening (19) leading out of the vessel. In the entire region lying within the vessel, a sealing cylindrical surface (20), surrounding the transverse openings (17, 18) is provided between the rotor (16) and the rotator (15) while in the region lying in the vessel wall (14) a clearance (22), compensating for the different thermal expansions of stator and rotor, is provided in order to prevent the unit from seizing. A gate system is thus provided which is very simple and space-saving and functions with high operational reliability.

Abstract: Multitubular sheaths with a reinforced structure for lead-acid battery electrodes, particularly suitable for filling with lead oxides blend in liquid, slurry or creamy paste form, having porosity characteristics which permit the outflow of liquid, keeping the oxides on the inside. The fabric with which said sheaths are produced is formed, in warp, by continuous elastic high-tenacity polyester yarns, twisted and thermoretractable; in weft, alternately by an elastic multifilament yarn of high tenacity, thermostabilized, and with a twist of at least 200 turns per metre, and a high tenacity multifilament yarn textured or voluminized and/or twisted and stapled. The combination of continuous elastic high tenacity multifilament yarns, highly twisted, and high tenacity voluminized stapled yarns produces a fabric characterized by high mechanical resistance,by very good resistance to oxidation, by longitudinal and trasversal elasticity and by high porosity, this latter created not only by mesh openings (macroporosity) but also inside the voluminized and stapled yarn itself (microporosity).
