Abstract: TITLE OF THE INVENTION:  APPARATUS FOR FILLING A TRANSPORT CONTAINER          ABSTRACT OF THE DISCLOSURE:    An apparatus for the controllable filling of transport containers with piece goods is provided.          The transport container is arranged vertically above  the  conveying  device  and  comprises  two halves  that  are  controllably  adjustable.    A lifting member is provided under the conveying means which penetrates the conveying means in the direction of the transport containers and may be introduced into the transport containers.   The lifting device is drivably connected to a control member that engages the halves of the transport containers.  With the control member, one or both halves of the transport container may be adjusted with respect to the  lifting movements of the lifting  device.     It  is  thus  possible  to automatically  fill  a transport  container with piece goods in a single layer or multiple layers, without  the  piece  goods  being  touched  by personnel.

Patent CA-2041157-A1 (CA)
Inventor: KRIEBEL MANFRED
IPC: B01D53/77
Filed: 1991-04-24
Abstract: ABSTRACT                A  process of purifying a gas which con-tains combustible components as well as carbon dioxide and sulfur compounds, particularly H2S, in that the gas is scrubbed in a scrubbing zone with a scrubbing solution, which is regenerated and re-used. The scrub-bing solution to be regenerated is pressure-relieved, stripped, and heated in a hot regenerating zone. An exhaust gas which is rich in H2S and comes from the hot regenerating zone is partly combusted in a combustion chamber with oxygen, oxygen-containing gas or air. A gas mixture which is at a temperature in the range from 1000 to 2000 °C and in which at least 30 mole percent of the sulfur supplied to the combustion chamber are contained as elementary sulfur and which also contains the compo-nents H2S and SO2 in a molar ratio of 4:1 to 1:1 is produced in the combustion chamber. The gas mixture is cooled below the dew point temperature of sulfur; con-densed elementary sulfur is removed; the gas mixture is subsequently heated to temperatures of 180 to 280 °C and is then directly subjected to a catalytic hydrogenation and/or hydrolysis, whereby the residual content of SO2 is substantially converted to H2S. At least part of the gas which has thus been treated is contacted as an H2S-containing residual gas with scrubbing solution.

Title: A hybrid balance and combination codec filter circuit
Inventor: NASEER ABSAR
IPC: H04M3/00
Filed: 1991-05-15
Abstract: A hybrid balance and combination codec filter circuit used in a subscriber line interface circuit over which a connection is established between a digital switching network and a subscriber instrument.  The hybrid balance and combination codec filter circuit in combination includes a transmit section that converts differential voltage audio signals representing voice transmissions transmitted from the subscriber instrument into Pulse Code Modulated (PCM) encoded digital data, for transmission to the digital switching network.  A receive section converts PCM encoded digital data representing voice signals switched through the digital switching network into differential voltage audio signals for transmission to the subscriber instrument.  An included hybrid balance and echo cancellation section connected between the transmit section and the receive section reshapes the audio band signals output by the receive section.  The reshaped audio band signals are applied to the transmit section, where they cancel any reflected audio band signals not completely transferred to the terminating impedance. Finally, an impedance section provides an audio band feedback signal between the transmit section and the receive section for synthesizing a source impedance that is matched to the impedance of the tip and ring leads of the subscriber loop.

Patent CA-2050039-A1 (CA)
Title: Lossless snubber
Inventor: CARROLL BARRY N
IPC: H02M3/28
Filed: 1991-08-27
Abstract: LOSSLESS SNUBBER                  ABSTRACT OF THE INVENTION      A capacitor connected directly across the terminals of the primary inductance of a transformer of a switched mode power supply and a separately wound inductor connected between the primary inductance and the switching power transistor which form a lossless snubber circuit.  The snubber circuit is more efficient since resistors are not used to dissipate the energy as unwanted heat.  The capacitor increases the transistor turn off voltage rise time, thereby reducing radiated emissions.  The inductor reduces emissions appreciably by absorbing the ringing that would otherwise occur after the transistor is turned fully off and increases the transistor turn on time to allow reduced emissions.

Abstract: A bottom-incidence type photo-sensing device has a pn junction, as a photo-sensing region, formed by selectively providing a first region of a second conductivity type in a portion of a semiconductive layer of a first conductivity type.  The first region is surrounded by a second region of the second conductivity type formed in the semiconductive layer, and the second region is of the same or larger depth as or than that of the first region.  Even when a light is directed to outside of the photo-sensing region, extra charges generated therein are absorbed by the second region and the flow of the extra charges into the photo-sensing region is prevented.

Title: Method for applying a protective coating to a high-intensity metal halide discharge lamp
Inventor: GORCZYCA THOMAS B
IPC: H01J9/20
Filed: 1991-11-28
Abstract: METHOD FOR APPLYING A PROTECTIVE COATING     TO A HIGH-INTENSITY METAL HALIDE          DISCHARGE LAMP           A method for applying a protective coating to the inner surface of the arc tube of a high-intensity metal halide discharge lamp involves dosing the arc tube with an inert gas that is doped with a metal hydride gas. Preferably, the metal hydride gas comprises silane.  The arc tube is heated to a sufficiently high temperature to decompose the silane gas.  As a result, silicon is deposited as a protective coating on the inner surface of the arc tube wall.  The hydrogen gas that is generated by the silane decomposition is removed from the system either by pumping it out before dosing the arc tube with the final arc tube fill, or by diffusion through the arc tube wall during operation of the lamp.

A number of electronic documents in digital data format are coupled to and stored within random access memory within the portable  computer  device  via  an  interface  from  a  host computer,  as  strings  of  characters  which  may  comprise encoded words,  syllables or phonetic codes.  The portable computer device preferably utilizes a limited number of tape recorder-like switches.   In response to a single operation of  a  "play" switch,  these electronic documents are then sequentially   coupled   to   a   text-to-speech   conversion application  and  converted  to  audible  speech  through  a speaker or headphone.   In one  embodiment of the present invention the portable computer device includes a microphone and analog-to-digital conversion circuitry which permit a spoken  input  to  be  digitized,  stored,  and  replayed  in conjunction  with  a  selected  electronic  document.   In  a scanning mode of operation, each electronic document may be sequentially accessed and the author,  subject matter and length  of  that  document  announced  audibly  to  the  user. Further,  all  electronic  documents  may  be  sequentially searched to locate each instance of a selected textual entry by a simple manipulation of switch devices.
