The opening has on one hand surface portions of a shape corresponding to the shape of the shaft, cylindrical or tapering, and on the other hand, surface portions having a shape corresponding to the shape of the clamping surfaces of a clamping sleeve, for allowing optional attachment of the machine member directly on the shaft or by means of the clamping sleeve.

Abstract: A fuel injector (3) has a plunger (7) with an oblique control edge (12). The plunger (7) is driven by a drive unit (20) which is acted upon by fluid pressure separate from the fuel system. The plunger (7) is rotatable around its longitudinal central axis (8) by means of a setting device (60). A control device (31) regulates the inflow and outflow of fluid pressure to a double acting piston (22) of the drive unit (20). A signal for beginning an injection cycle is given by an electric pulse generator (40) or a control camshaft (61) of the control device (31). A return piston (34) of the control device (31) is acted on by fuel pressure and is connected through a line (33) with a pump chamber (6) of the fuel injector (3). At the end of the injection cycle the control edge (12) opens a passage (14) to pressure in the pump chamber (6 ) and a pressure surge acts through the line (33) on the return piston (34).

Abstract: A pharmaceutical composition comprises an anti-epileptic drug that does not inhibit, enhance or otherwise modify dextromethorphan binding to the central nervous system dextromethorphan receptor and an effective amount of dextromethorphan to potentiate the anticonvulsant activity of the drug. Other related compounds similar to dextromethorphan which inhibit or enhance dextromethorphan binding to the dextromethorphan site in the brain are also suitable as potentiating agents for the anticonvulsants. A method of treating epilepsy and other convulsions include the steps of introducing to the patient an effective amount of the compound comprising an anti-epileptic drug and potentiating amount of dextromethorphan or one of the related compounds.

Abstract: An improvement of pistons for alternative, endothermic four-cycle engines, in which notches or grooves are cut on opposite sides of the oval surface of the piston skirt and arranged in a parallel fashion with respect to the piston pin. The grooves create concavities which are closed off frontally by the cylinder wall and laterally by the piston skirt. The purpose of the grooves is to create a series of pockets for the lubricating oil, which is under pressure during engine operation, and to improve lubrication in the areas of maximum piston stress.

Abstract: A novel asphaltic composition consisting of from about 2% to about 10% w/w of a hydrocracking residue which is the distillation residue obtained from a hydrocracking process of heavy crude oil in admixture with from about 98% to about 90% w/w of a conventional asphalt. These asphaltic compositions are especially useful when mixed with mineral aggregate to provide road mixes which lead to improved road construction or road paving.

Abstract: In an ion implanting apparatus, a first conductor member for monitoring the charge-up of the workpiece is positioned on the front face of a wafer disk, a second conductor member electrically connected with the first conductor member for distributing the charge on the first conductor member is positioned on the rear face of the wafer disk, and a third conductor capable of forming capacitive coupling with the second conductor member is fixed to a disk chamber. When the first conductor member is charged, the charge is distributed also to the second conductor member. When the second conductor member passes by the third conductor member by the rotation of the disk, charge is induced on the third conductor member depending on the charged state of the second conductor member. The first, the second and the third conductor members can be effectively shielded from the surroundings. Charge detection with a high S/N ratio is made possible.

The proximal thermistor is so positioned as to be substantially totally immersed in the blood-injectate mixture to rapidly and accurately determine the temperature thereof. The use of two thermistors so placed provides highly accurate temperature data requiring substantially no correction.

Abstract: Fiber boards of high strength which are highly water- and flame-resistant are disclosed, as well as a method for making such boards and an inorganic binder composition for bonding wood fibers. The boards comprise a lignin-containing fiber material, a binder derived from a binder composition comprising an alkali silicate solution, sulphur and/or an inorganic sulphur compound, and a calcium and/or magnesium compound and, optionally, fillers and/or hydrophobing agents.The fiber boards are manufactured by mixing the lignin-containing fiber material with the binder composition and optional further additives, whereupon the mix is compressed at a high pressure and at a temperature of 130.degree.-230.degree. C.

Abstract: A low loss synchronous magnetic drive system for high pressure, high horsepower applications is disclosed. A carrier member driven by a drive motor carries spaced apart sets of drive magnets with the magnets of one set being of opposite polarity to the longitudinally aligned magnets of the other set. An output shaft carrying driven magnets oriented similarly to the drive magnets is also provided. A metallic hyperbaric barrier separates the drive and driven magnets. The barrier includes an outer cylinder having circumferentially spaced, radially directed, narrow slots extending therealong. Within the cylinder is a plurality of axially adjacent annular laminations insulated from each other. During operation the combination of the slotted cylinder, the laminations and the magnet arrangement keeps eddy currents generated in the barrier at a minimum, ensuring a high efficiency drive operable at speeds and pressures heretofore unattainable.
