IPC: B65G17/00
Filed: 1993-04-27
Abstract: A conveyor system is disclosed for transporting workpieces. The conveyor system includes an elongated frame having an inlet end and an outlet end. A pair of sprockets are rotatably mounted to both the inlet end and outlet end while a pair of closed loop chains are mounted around the sprockets so that the chains are spaced apart and parallel to each other along the frame. A motor rotatably drives the sprockets and thus the chains along the frame.

Abstract: A system for making a summary video for monitoring at least one lane at a transaction site uses a camera means (12a, b etc.,) for generating video signals corresponding to a view of at least one of the transaction lanes. A register (24a, b etc.,) at each lane is responsive to activity at the lane for generating a transaction signal representing the occurrence of transactions at each lane. A computer (40) is responsive to the transaction signals to generate a transaction summary signal representing an alphanumeric display of the transactions, and a video storage signal upon the detection of a user-defined transaction signal. A recorder (50) is responsive to the video storage signal to store the video signal corresponding to a frame of video of the transaction lanes substantially at the time the user-defined transaction signal was generated. The system further comprises overlay means (60) responsive to the transaction summary signal and the stored video frame signal for generating a composite video signal and a monitor (64) responsive to the composite video signal for displaying the frame of video with the alphanumeric display overlayed in a predetermined position. <IMAGE>

Abstract: Abstract of the Disclosure A process is provided whereby the hydrogen peroxide-containing oxidate from methyl benzyl alcohol oxidation is extracted with water and with ethyl benzene extractive solvent and an aqueous hydrogen peroxide phase is separated from an ethyl benzene solvent phase which also contains methyl benzyl alcohol and acetophenone, the improvement being that ethyl benzene is introduced into the extraction zone below the point of introduction of the oxidate, thus avoiding the possibility of formation of an aqueous hydrogen peroxide phase concentrated to a hazardous degree in hydrogen peroxide in the extraction zone.

Title: Methods and apparatus for detecting bacterial growth by spectrophotometric sampling of a fiber-optic array
Inventor: BLUMENFELD WALTER
IPC: C12Q1/06
Filed: 1993-07-07
Abstract: The detection of bacterial growth or the performance of other interrogative processes in multiple sample vials is accomplished using a moving rack that selectively couples optical locations to an optical excitation/detection system. The apparatus includes a drive mechanism combining agitation of the culture vials with a sequential scanning of an array of optical fibers, preferably by a spectrophotometric excitation/detector system.      Selection of each culture vial provides, for example, optical detection of bacterial growth by fluorescence or other spectrophotometric measurements. A rack for holding vials is preferably the only moving assembly, and requires no mechanical or electrical interconnection with the excitation/detection system for its operation. In general, the present invention relates to the optically indexed presentation of the optical guides, e.g., the emission and excitation fibers, to many remote sample sites in the form of a geometric array at the interface between the moving culture vial rack assembly and the spectrophotometric excitation/detection system fixed to the body of the instrument. Methods of transmitting and receiving electromagnetic radiation to and from sample vials held in a movable rack include the steps of coupling the sample vials to an optical fiber and terminating the optical fiber at an optical coupling location. The rack is then moved to align at least one of the coupling locations with an excitation/detection system.

Title: Semiconductor optical component and manufacturing method therefor
Inventor: ONO TAKAHIRO
IPC: H01S5/20
Filed: 1992-11-20
Abstract: A process for manufacturing a semiconductor optical part in which a ridge type semiconductor optical amplifier section and a ridge type semiconductor optical waveguide connected to the optical amplifier section are integrally formed on a single substrate. The semiconductor optical amplifier section has a path width narrower than that of the semiconductor optical waveguide. The current density of the semiconductor optical part thus manufactured can be high since the injected current in the semiconductor optical amplifier can be much constricted. Therefore, optical amplification of a high efficiency can be performed even in the case of a small injected current, and the semiconductor optical part is useful as an optical amplifier of a high efficiency.

Inventor: PRIMDAHL IVAR I
IPC: C01B3/38
Filed: 1993-08-12
Abstract: A process is provided herein for the preparation of a gas which is rich in hydrogen and/or carbon monoxide. The process includes the partial oxidation of a hydrocarbon feedstock in a reactor with an upper portion, a lower portion, and a refractory lining which is attached to an inner surface of the reactor. The process includes the first step of introducing the feedstock and an oxygen-containing gaseous atmosphere into the upper portion of the reactor. That feedstock is then partially oxidized with oxygen in the upper portion of the reactor. A part of that partially-oxidized feedstock is then contacted with a reforming catalyst which is arranged on the refractory lining in at least the upper portion of the reactor. In this way, the lining is cooled by endothermic reforming reactions proceeding in the partially-oxidized gas on the refractory lining.

IPC: B24B13/005
Filed: 1993-11-23
Abstract: A computer is used to calculate the location of a target, customize the target to conform to the lens, frame and patient characteristics  of  each individual  job and automatically compensate for parallax in the apparatus.  A convenient open work surface is provided for the operator to position the lens blank on a non-skid surface.   The block is applied at a constant limited force in a manual or automatic mode of operation on either frame or optical center.  The offsets for positioning the lens blank are calculated within the blocker based upon frame and patient data.  This data can be input directly or can be downloaded from a database.  These offsets determine the location of the target relative to the optical markings on the lens blank.  The amount the target is offset is scaled automatically to compensate for the fact that the lens blanks  are on  a work  surface  above  the  electronic display.  A customized target is displayed.  The target is scaled to match the segment widths for multi-focal lenses, and provides a centered target location with multiple horizontal lines for single vision lenses, including progressive lenses. Scaling  of  the  width  eliminates operator  judgement  to "eyeball" the center.  The multiple horizontal lines provide an additional aid in aligning progressive lenses where the distance from the "mounting cross" to the horizontal line on the lens blank varies by manufacturer.  The frame shape may also be displayed to provide a sense of fit.

Title: Talking playset
Inventor: ARAD AVI

Filed: 1994-01-12
Abstract: TALKING PLAYSET                  ABSTRACT OF THE DISCLOSURE          A toy playset includes a doll house with one or more socket type receptacles located on the floors of each of several rooms.  The receptacles interchangeably receive any of three different toy figures.  Each figure has a distinct outer appearance identifying the figure and is uniquely encoded by identifying rings in its base which activate selected switches in any of the receptacles in which it is placed.  A processor/synthesizer powers and polls the status of the switches and identifies through the switches each receptacle receiving a figure and the figure received.  The processor/synthesizer generates a unique sound response to the state of the playset in the form of a monologue or conversation, whichever is appropriate.  The unique sound response depends upon each particular figure being sensed and the location of the receptacle receiving it.  In the case of two or three figures being received in receptacles, the unique sound response also depends upon the order in which the figures were received in the receptacles.  The sound response may be further varied depending upon the state of a time switch indicating day or evening and the orientation of any character placed in a receptacle located at the front door of the doll house.  Selected sound effects may be generated at any time through a plurality of momentary switches.
