Title: Apparatus for driving a wobbling body
Inventor: MEYER PIO
IPC: F16H35/00
Filed: 1993-05-26
Abstract: ABSTRACT         A tumbling oloid hollow body (4) is placed on and driven by a belt (2) to receive materials. The tumbling motion is forced by the fact that the trace points of the axis of a hollow shaft (6) piercing the hollow body (4) in its longitudinal axis are forced onto oval paths by two planes parallel to each other that are upright and run i the longitudinal direction of the belt (2) and are located on each of its longitudinal sides. Each of these planes is defined by a frame (11), and each of these frames (11) carries an oval guiding rail (8) that is circled by a carriage (9) and attached to the frames with at least four spring attachments (10). This carriage (9) houses the positioning and guiding elements for the shaft (6). The tumbling hollow body (4) has a closeable opening (5) for the addition and removal of mixing material, If the shaft (6) is hollow, mixing materials can be added and removed during the hollow shaft (6). Two segment-like areas (7) can be cut off from the oloid hollow body (4) and could be pierced by the shaft (6). This will result in a narrower belt (2) and space for the shaft (6) (Fig. 2a).

Abstract: ABSTRACT OF THE DISCLOSURE   A apparatus for positioning optic fibers relative to an object to be sensed including a body having two or more apertures or channels for positioning an emitter optic fiber and at least one detector optic fiber relative to a photoreceptor, sheet or other object to be sensed. The emitter optic fiber projects a light beam toward the object, while one or more detector optic fiber(s) receive light reflected of of the object. Detector optic fibers transmit the light beam reflected from the object, or in the absence of an object, from a reflector to a detector. The detector generates a signal in response to receiving the light beam. The apparatus may also be adapted to detect the density of toner applied to a photoreceptor, colors on a surface, or other conditions.

Filed: 1994-04-05
Abstract: The object of the invention is a cable reel, which includes a drum (2) made from sheet steel and ends (1) i.e. flanges attached to both sides. Curved tabs (4) are formed in the ends (1) of the drum (2) and extending in an axial direction through the ends (1), to which tabs corresponding curved slots (11) are formed. The parts of the tabs (4) extending from these slots (11) beyond the ends (1) are bent onto the external surface of the ends (1).  The length and width of the tabs (4) in the direction of the circumference are so great taking into account the thickness of the sheet steel of the drum (2) and the diameter of the drum that the deformation work involved in bending the tabs due to the curved tabs is many times greater than compared to the bending of a straight tab. The invention is also concerned with a method for manufacturing the cable reel.

Title: An electrical method for conversion of molecular weights of particulates
Inventor: SACKINGER WILLIAM M
IPC: C22B4/00
Filed: 1994-03-25
Abstract: An electrical apparatus is provided for the conversion of compounds, elements, or mixtures which are in particulate form, into new compounds, elements or mixtures in gaseous, liquid, or particulate form.  In a reaction chamber, particulates are mechanically transported into a first region of high electric field, where they acquire a charge and are projected into a second region in which a low-density plasma is maintained.  Energetic plasma ions strike the surfaces of the particulates, causing chemical reactions and release of both neutral and ionic products species.  Charge exchange on particulates causes the reduced-size particles to fall back into the first region, where the charging recurs and the cycle is repeated. Gaseous and particulate products are removed from the chamber. In one application, naturally-occurring ores may be reduced by a methane plasma; in another, coal may be converted in a methane plasma to intermediate range hydrocarbons.
