Title: Arrangement for synchronizing data signals in an optical switched system
Inventor: CAMLET JOHN V
IPC: H04B10/43
Filed: 1993-06-28
Abstract: Abstract of the Disclosure A synchronization arrangement achieves very fast synchronization for a received data signal in an optical switched system. Phase synchronization of received data with an internal clock at the receiver is provided by synchronizing the received data to the internal clock. In the operation of the arrangement, the received data signal from a remote transmitter is reproduced a predetermined number of times and each one of the reproduced data signals is coupled through one of an array of delay lines. Each delay line has a different delay and is arranged in an increasing order such that progressively longer or staggered delays for the received data signal is provided in the form of these reproduced, delayed data signals. Each one of the reproduced, delayed data signals is examined for determining the period of time therein during which the incoming data is high and the period of time during which this data is low, in relation to the internal clock signal. With the phase relationship between each delayed data signal and the internal clock determined, the synchronizing arrangement selects the correct one of the delayed data signals which is most closely in phase alignment with the internal clock at the receiver. Once the received data is synchronized, the receiver works completely synchronously without any additional clock adaptation for the period of receipt of the received data.

Title: Regulation of flowrate of liquid furnace products
Inventor: GRAY NEIL B
IPC: F27D3/15
Filed: 1992-02-18
Abstract: The invention relates to an apparatus and method for regulating the flow rate of a liquid furnace product. The apparatus comprises a heat exchange jacket (10) surrounding a conduit (9) through which liquid furnace products flow. The heat exchange jacket (11) removes sufficient heat from the conduit and product flowing therein to cause a shell of solidified product to form on the internal surface of the conduit. The flow rate in the conduit is controlled by regulating the coolant flow through the heat exchange jacket and consequent shell thickness.

Patent CA-2107643-A1 (CA)
Inventor: WALL ALEXANDER
IPC: B41K1/20
Filed: 1993-10-04
Abstract: In  a  hand  stamp  mount  device  especially suitable for a preinked stamp impression member that can give great numbers of imprints, the downstroke distance of a substantially rigid,  non-rotatable assembly of a handle, a stem and a platen for carrying the impression member is adjustable precisely by turning with one's fingers an adjuster that correspondingly turns a stroke limiting stop member and causes it upon turning to be displaced  proportionately  lengthwise  of  the  stem. Several ways of effecting the adjustments are disclosed, including  some  which  eliminate  all  need  for screw-threaded parts by making use of a molded ramp member presenting helical ramp surfaces.  The platen and a case enclosing it are stiffened to resist stamping forces by an array of integral radiating ribs protruding upwardly from  the  platen  and  another  array  of  such  ribs protruding downward from the top of the case: and the ribs of the two sets  intercalate to occupy vertical space in common when the platen is in normal upward position.  A cover closing the case presents structures which  limit  downward  movement  of  the  platen,  and structures connecting the cover with the case resist removal of the cover otherwise than by force applied to an end thereof.   Further, the handle of the device is provided  with  an  asymmetrically  rounded  knob  form enabling reliance on the feel of it in a user's hand for securing right-reading stamped imprints.

Title: Use of data communications equipment interface leads to signal half-duplex or full-duplex operation
Inventor: SCOTT ROBERT E
IPC: H04M11/06
Filed: 1993-12-15
Abstract: Use of Data Communications Equipment Interface Leads to Signal Half-Duplex or Full-Duplex Operation Abstract The Electronic Industry Association (EIA) RS-232 interface signals are manipulated to additionally convey operating mode information from a piece of data communications equipment (DCE) to its respective data terminal equipment (DTE). In particular, in establishing a data connection, the data communications equipment may transmit information in either half-duplex mode or full-duplex mode. In order to convey which mode of transmission is being used, the data communications equipment manipulates the EIA RS-232 interface signals to provide a notification signal, which is representative of the particular mode, to the data terminal equipment. As a result of receiving this notification signal, the data terminal equipment can then switch to the same mode of operation. (FIG. 1)

Title: Method for mapping between object-oriented models and relational models, or between two object models
Inventor: SITARSKI EDWARD M
IPC: G06F9/44
Filed: 1994-10-18
Abstract: ABSTRACT OF THE DISCLOSURE A mapping is produced from an object model to a relational model including specifying the search area by preparing subgraphs to specify a semantic query, applying the specifying step by using subgraph isomorphism to determine a set of matches of a set of nodes between the subgraph and the object model,  and mapping particular information of the matched nodes (typically stored in the form of data) to the relational model.  A reporting is produced to describe the relations between the nodes in the object model which is translated to the relational model along with the specific data contained therein.  Using the results of the reporting as well as the specific data, the information contained in the relational model may be mapped into a second object model with the relations between the nodes created by the reporting.

Title: Semiconductor surface emitting laser having enhanced polarization control and transverse mode selectivity
Inventor: CHOQUETTE KENT D
IPC: H01S5/062
Filed: 1994-03-14
Abstract: SEMICONDUCTOR SURFACE EMITTING LASER HAVING ENHANCED POLARIZATION CONTROL AND TRANSVERSE MODE SELECTIVITY Abstract Applicant has demonstrated that by appropriately shaping the laser gain region one can control the polarization direction of semiconductor vertical cavity lasers and enhance their transverse mode selectivity. Specifically, configuring the transverse cross section to regions have a length-to-width ratio in excess of 1.2 favors emission with polarization in the long dimension at the fundamental mode. A cruciform structure favors emission with switchable orthogonal polarization. Thetransverse shape can be configured by dry etching a particular cavity shape in index guided lasers or by forming a shaped ion implantation region around gain guided lasers.

Title: Fuel burner control system with selectable standing pilot mode
Inventor: ANDERSON GREGORY W
IPC: F23N5/20
Filed: 1993-10-21
Abstract: A burner control system with an interrupted or intermittent type of pilot burner has a special feature allowing transitions between a pilot flame hold state where the pilot flame only burns and the run state where the main burner is operating. Each transition to the pilot flame hold state from the run state comprises a brief period in which presence of the pilot flame is assured while the main flame is extinguished. Transitions to the run state from the pilot flame hold state may proceed directly through the main flame establishment period to the run state, thereby eliminating the time-consuming purging and pilot flame ignition phases.

Title: Apparatus for Wrapping Articles in Plastic Film
Inventor: MORANTZ JACK I
IPC: B65B11/02
Filed: 1994-06-09
Abstract: Apparatus for wrapping articles in film material includes   a   stationary   frame   supporting   a   vertically reciprocable frame which in turn supports a rotatable, ring member carrying a film carriage assembly by which film is wrapped around an article during rotation of the ring member. The ring is in the form of an outwardly open channel and is supported for rotation relative to the reciprocable frame by wheels  on the  latter which underlie  the  upper flange of the channel.  The web of the channel is captured between pairs of wheels mounted on the reciprocable frame, and a wheel of one of the pairs is driven to rotate the ring relative to the reciprocable frame.  The reciprocable frame is elevated and lowered relative to the stationary frame by a  chain  drive  arrangement,   and  the  stationary  and reciprocable frames have interengaging guide components at two diametrically opposed locations.
