Inventor: EWEN JOHN A
IPC: C08F4/64
Filed: 1987-09-21
Abstract: The present invention provides a catalyst system for the polymerization and copolymerization of olefins with the system comprising a chiral, stereorigid hafnium metallocene catalyst in combination with an aluminum compound. The aluminum compound is preferably an alumoxane and may be a mixture of alumoxane and trimethyl aluminum. It was discovered that this mixture causes a transformation of the catalyst over time. The catalyst system may also include a solvent to increase the solubility of the metallocene catalyst. It was discovered that these catalyst systems produce useful polymer products with molecular weights greater than 10,000.

Abstract: The invention relates to a pump element of a fuel injection pump for an injection combustion engine in which the pump piston lining (2) has at least one intake and overflow hole (3), over which control edges (4, 5) of the pump piston pass, at least one control edge (4) located in the area of the piston end face determining the start of pumping and at least one control edge (5), in particular an angled one, on the piston skirt determining the end of pumping. A flow- restricted connecting line is provided between the working chamber (8) of the piston and the intake and overflow hole (3), which is open already when pumping commences or shortly thereafter so that the vapour locks in the intake and overflow hole (3) are promptly removed. This is achieved in that in the area of the intake and overflow hole (3) the piston skirt has a surface recess (6) extending out from the piston end face (4), or in that the piston sliding surface (11) of the pump piston lining (2) on the side of the intake and overflow hole (3) facing the working chamber (8) of the pump piston (1) has a surface recess (12) extending from this hole, or in that a slot (13) running in a circumferential direction in the piston skirt (14) is located just below the piston end face (4), which slot is connected to the working chamber (8) of the pump piston (1), for example via an axial slot (15). <IMAGE>

Abstract: Multi-column pressure swing adsorption process for simultaneous pro­duction of ammonia synthesis gas and carbon dioxide from a reformer off gas having hydrogen, nitrogen and carbon dioxide as major components ac­companied by minor quantities of methane, carbon monoxide and argon as impurities. The PSA system features two groups of adsorbent columns in which CO₂ is adsorbed in adsorbers of the first group, the essentially CO₂-freed effluent being charged to an adsorber of the second group for removal of minor impurities while discharging an effluent gas having an H₂/N₂ content stoichiometric for NH₃ synthesis. The CO₂ recovered from the first group of adsorbers is available at a high purity for re­action with the ammonia product for production of urea.

Abstract: Longitudinal differential protection system for protection and supervision of power line zones in a distribution system. The protective relays, comprised in the system, are located at each end of the zones that are desired to be monitored. One of the protective relays operates as a master relay for the other slave protective relays. A TRIP function indicating a line fault in any protected zone is performed by transmitting locally processed measured signals to the central protective relay which determines if and when any measure is to be taken. Each local protective relay comprises a measuring device (1), a filter (2) and an AiD converter (3) for phase currents and phase voltages. The digital signals are used to generate a truncated Fourier model of the measured signals in a parameter estimator (4) which cooperates with a frequency estimator (5) and a sampling regulator (6) which, via a synchronization unit (7), ensures that sampling is performed simultaneously in all protective relays included in the protective system. In the parameter estimator the residuals (e x (t)) of the phase quantities are also generated. Fourier components and residuals are supplied to a logic unit (8) where local loss functions (V Lx (t)), based on the residuals, are compared with set threshold values for evaluation of whether an abrupt event in the network has occurred. The current direction and the signs of the residuals at each local protective relay are also determined. By a study of the Fourier components an evaluation can be made as to whether the event is due to a conventional line fault or to a switching in the network. If the event is due to a line fault, information obtained from all local protective relays is transmitted, code-compressed via a signal compression unit (9), to the master protective relay which also comprises a central logic unit (10), wherein a central loss function (V Gx (t)), based on the sum of all the current residuals during a certain time from all protective relays, is formed. If this loss function exceeds a threshold value (η G ), a TRIP function is released.

A body (1) of a machine tool is provided with a work mounting table (2). This table (2) is provided with a rotary table (31. In order to machine the work, the work is set on the rotary table (3). In order to subject the work to a process other than a machining process, the work is set on the table (2). In the latter case, the work can also be set on the table (2) and rotary table (3) as necessary so that the work extends over both of them.
