A type of internal cycloidal gearing based on the principal that different size generating circles rolling inside a directing circle which has a diameter equal to the sum of the diameters of the generating circles generate identical hypocycloids, and, similarly, a generating circle that surrounds a directing circle and gyrates around it like a "hula-hoop" generates the same epicycloid as a small circle having a diameter equal to the difference in the diameters of the surrounding "hula-hoop" circ...

A novel internal olefin or mixture of internal olefins having the formula R--(CH.sub.2).sub.2 --C(R)=CH--C(R)(CH.sub.3)--(CH.sub.2).sub.2 --R, where each R group is an alkyl group having from four to 12 carbon atoms, is prepared substantially free of olefin isomers by the dimerization of a vinylidene compound in the presence of boron trifluoride complexed with a lower alkyl alcohol. The dimer of 2-octyl-1-dodecene is 11,13-dioctyl-13-methyl-11-tricosene. This vinylidene dimer is useful as a high...

An exhaust gas recirculation (EGR) system for use in a four-stroke, internal combustion, compression-ignition engine having at least one engine cylinder, at east one combustion chamber, at least one intake valve and a crankshaft. The EGR system includes at least one exhaust gas intake valve that is opened during at least a portion of an engine intake stroke when the exhaust gas pressure is greater than the pressure of gas in the combustion chamber, thus allowing exhaust gas to flow into the comb...

A miniature spherical-shaped internal temperature transponder. A temperature sensor (25) is fabricated in a spherical integrated transponder circuit (15) which may be placed in the human body by ingestion, implantation, or injection. In one aspect of the invention, a passive system is disclosed whereby an external monitoring station (13) generates an energy field using a magnetic field generator (19) which is coupled to a power coil (21) of the transponder (15). The power coil (21) passes power ...

The present invention relates to a teat cleaning device having cleaning surfaces (27) on a base (9) wherein the cleaning surfaces (27) can be moved from a first position near to the periphery of said base (9) to a second position nearer to the center of said base (9).

A broach for internal broaching is formed on its pull end and/or follower end with a tapered surface machined with high accuracy. A pull head and/or a retrieving head of a broaching machine, which drivingly grip the pull end and the follower end the broach, is formed with a tapered inner surface complementary to the tapered surface of the broach. The pull head and the retrieving head grip the broach while pressing and clamping their tapered inner surface against the tapered surface, and these he...

An internal lock (E) for safes and similar applications, with an outer console (A) that includes software with the instructions required by the user, which is connected by that passes through the wall of the safe to the lock. The latter includes a printed circuit linked to the one in the console and is operated by a power supply (D) connected to the mains. A simple mechanism composed of a latch (5), a motor (7), gears and a trigger are responsible for the operation of the latch, in accordance wi...

An internal filter that may be installed or removed from the outside of the housing. The internal filter may also cooperate with an inlet passage for a charge pump.

An internal connector including a carrying portion, a connecting portion, an elastic component and a second positioning component is disclosed. The internal connector is installed in an electronic apparatus with an insert card device. The connecting portion having a first positioning component is equipped on the carrying portion. And the first positioning component includes an initial structure and a stopper. The connecting portion is used to be connected with the insert card device and to slide...
