Abstract: A digital radio telephone gives information to user in speech form by using an advanced speech coder/decoder in a digital  radio  communication  network.     Such  an  advanced coder/decoder can reduce quantity of coded data to be stored.          The digital radio telephone according to a first embodiment includes a speech coder/decoder, a speech information memory, a speech information retrieval table, an operational information controller,  and  a  speech  information  reading  section. A plurality of predetermined speech signals are stored in the speech information memory in coded form.  The speech information retrieval table stores information for producing a voice message to the user using the items in the speech information memory.          To give the voice message to the user, the information is read out by the operational information controller and necessary items of speech signals are read out by the speech information reading section in sequence according to the read information.   The speech voice coder/decoder decodes the items so as to produce the voice message in the same way as with digital speech voice signals received by the digital radio telephone. According to a second embodiment, the user can store his own voice into the speech information memory in coded form,  and when the user operates the telephone, the user will hear the voice messages in his own voice.

Title: Process for purifying exhaust air
Inventor: KRATZ GUNTHER
IPC: B01D53/22
Filed: 1992-03-16
Abstract: ABSTRACT OF THE DISCLOSURE The invention concerns a process for cleaning exhaust air containing biodegrad-able contaminants which arc only slightly soluble in water. The contaminants are ab-sorbed by a washing liquid containing activated sludge and at least one high boiling solvent for the contaminants and are decomposed by the activated sludge. The solvent and the activated sludge are separated from at least part of the remaining washing li-quid which is then drained off. In order to reduce significantly the amount of sub-stances which are dangerous to the environment or to health in the washing liquid sep-arated off, it is proposed that part of the remaining washing liquid be separated off by membrane filtration using inorganic or hydrophilicized organic membranes. Silicone oil is a particularly suitable solvent for use in the process.

Title: Erase unit for ion deposition web-fed print engine
Inventor: POLLUTRO DENNIS C
IPC: G03G21/06
Filed: 1993-10-21
Abstract: An erase unit for an ion deposition web-fed print engine includes a plenum extending the width of the electrostatic image on the image cylinder and defining an information chamber with the image cylinder surface. The plenum has first and second electrodes separated by a dielectric. Upon application of a time-varying potential having a frequency of 0.2 to 50 mHz across the electrodes, ionization occurs, causing an ion current flowing in relation to the image surface until the image surface and the biasing electrode are at the same potential, thus erasing any residual electrostatic image on the cylindrical surface. By providing a DC biasing voltage, the residual electrostatic image may be erased when equalization occurs, with the image cylinder maintaining a pre-charged potential.

Title: Robot cutting system
Inventor: BURCH RONALD H
IPC: B26F3/00
Filed: 1994-07-05
Abstract: ABSTRACT OF THE DISCLOSURE    A computer-controlled robot cutting system for making angled or beveled cuts along a preselected path in a workpiece having a generally planar cutting surface.  A cutting knife, such as a high-intensity fluid jet, is pivotably mounted in a support frame having two pairs of arcuate guides disposed at right angles to each other for motor-driven rotation of the cutting knife about orthogonal axes.  The centers of curvature of both guides lie on a critical plane containing a pivot point about which the cutting knife pivots.  An opposing workpiece gantry with horizontal and vertical slides for motor-driven translation of the workpiece along two axes also includes means for holding the workpiece such that its surface to be cut faces the cutting knife and lies in the critical plane.  The workpiece is thus translated to define the cutting path on the obverse surface, while the cutting knife is pivoted to define the entry angle of the cut along the cutting path.  Four motion controllers under computer control coordinate the motors driving each axis of rotation or translation.  Because the obverse cutting surface of the workpiece is maintained in the critical plane containing the pivot point, pivoting of the knife does not change its entry point in the cutting surface, thereby simplifying motion control algorithms.  Furthermore, because the cutting knife is pivoted and the workpiece is translated, the relatively massive gearing and movable frame structures are distributed between the cutting knife section and the workpiece gantry, lowering the inertia and enabling the use of lighter-duty motors.
