Abstract: This invention relates to differential gears for mechanically propelled vehicles, and it is an object of the invention to reduce spinning of one wheel or axle of a vehicle in icy or muddy conditions. This result is achieved by feeding oil through passages in the sun gear to the meshing teeth of the sun gear and the planet wheels. Thus, if one wheel or axle starts to spin, there will be relative rotation between the sun gear and the planet wheels which will then act like a gear pump. The sun gear and the planet wheels are located in a relatively confined space so that the rate at which the oil can be dissipated is limited. The load caused by the oil pumping limits rotation between the sun gear and the planet wheels, and enables torque to be applied to the slipping wheel or axle.

Abstract: A virtually frictionless bearing element for use in a tape transport is formed from a piezoelectric material, with the tape being disposed proximate a surface of the piezoelectric bearing element. An ultrasonic signal (approximately 70 KHz) is applied to the bearing element causing the piezoelectric material to expand and contract at the signal rate. The vibrations cause a thin film of air to be generated at the surface of the bearing element over which the tape can pass with virtually no friction or wear. Roller inertia and flutter which are associated with ordinary roller-type bearing elements are eliminated since the only moving part is the tape itself. The bearing element can also be combined with a magnetic transducer to form a frictionless magnetic record/reproduce head.

Abstract: Passivation of vanadium accumulated on catalyst, e.g. crystalline zeolite hydrocarbon conversion catalyst in the rare earth and/or ammonia exchanged zeolite form, effectively minimizes the degrading characteristics of accumulated vanadium on the catalyst. The passivation is accomplished by impregnating or, preferrable, precipitating, rare earths, e.g. lanthanum, onto the catalyst particles before and/or after vanadium accumulation. The process is also applicable to inert sorbent particles, e.g. those used for removing carbon and metals from contaminated hydrocarbons.

Abstract: A power source off delay timer generates an off delay output after passage of a determinate time delay period from when an input power source is switched off. This timer includes a main body, a liquid crystal display mounted to the main body so as to display the operational condition of the timer, and a liquid crystal display drive unit for driving the liquid crystal display during the time that the power source is on and also during the determinate time delay period between the time instant at which the power source is switched off and the subsequent time instant at which the timer generates the off delay output. Thereby, the position of the liquid crystal display may be substantially arbitrarily selected, and also the position of the keep relay may be arbitrarily chosen. And because the liquid crystal display and also the drive unit therefore have typically very low power consumptions, it is possible to keep them in operation without exhausting the power source such as a capacitor for operating the timer after the power source has been switched off, even if the delay time period is very long. A variable resistor may be used for adjusting the time delay period; and the system may include a flasher circuit for flashing the liquid crystal display, to make its indication even more visible.

Abstract: (D A fastening means (1) for mounting a plate (45) optionally made of several smaller pieces of plate (41,42,43,44) onto a substantially planar wall (40). The plate (45) may for instance be a mirror composed of several smaller pieces of mirror or a relief made of several smaller pieces of relief. The fastening means comprises a bottom member (1) to be secured on the wall (40), and an intermediary member (15) secured atop the bottom member (1). The intermediary member may cooperate with the bottom member (1) and is adapted in such a manner that the distance (h) of its top surface (17) from the bottom surface (4) of the bottom member (1) is adjustable. The intermediary member (15) comprises projections for the support and/or carrying of the corners of the plate (45) or the pieces of plate (41, 42, 43, 44). A cover (30) is positioned atop the intermediary member and engages said intermediary member. Furthermore, the cover serves to secure the plate (45), optionally the pieces of plate (41, 42, 43, 44) to the intermediary member (15). In this manner it is possible to mount the plate onto a not completely planar wall without the risk of said plate presenting a skew surface. Furthermore it is possible for the plate composed of several smaller pieces of plate upon mounting to form a completely planar front surface without skew pieces of plate.
