Title: Rectification of a laser pointing device
Inventor: TREPAGNIER PIERRE C
IPC: G01B21/04
Filed: 1994-10-11
Granted: 2005-04-05
Abstract: Methods of compensating for errors in a laser pointing device, particularly for use in three-dimensional applications, by accurately controlling the angle that the laser beam makes in space. A method for rectifying a laser pointing device that aims a laser beam by deflecting the beam through a plurality of optical deflection devices each directed by a galvanometer controlled by an input. In the method, the laser pointing device is established in an accurate angular relationship to at least four fiducial points. The angular errors internal of the laser pointing device are determined by comparing actual galvanometer inputs to nominal galvanometer inputs, assuming no error in the established angular relationship. The actual galvanometer inputs are those that aim the laser beam at the fiducial points (while recognizing the existence of the internal errors), and the nominal galvanometer inputs are those that would aim the laser beam at the fiducial points assuming no internal errors in the laser pointing device. The angular errors are stored in a form for use during scanning by the laser pointing device to compensate for the internal errors in converting nominal direction numbers computed by a control to actual galvanometer inputs.

Abstract: Apparatus for cooling a tubular thin film thermoplastic resin in a melted state is described. The apparatus is capable of cooling the thin film from the inside and the outside thereof while setting its diameter by interposing the film between the mandrel and an external circular coolant storage tank. The mandrel has a cylindrical shape and is connected with the lower side of a circular-shaped extruding die wherein the film is extruded downward from a circular slit in the die. The mandrel includes an air-injecting nozzle for injecting compressed air that maintains the shape of an upper bubble part of the thin film formed between the die and the mandrel.      A coolant injecting nozzle which can inject the coolant toward the inner surface of the thin film is provided, the coolant injecting nozzle being formed into a single stage of circular slit or two or more stages of circular slits.  Also provided are a ring for setting the diameter of the tubular thin film, a discharge port positioned in a side face of the mandrel for discharging the coolant used for cooling into the mandrel, and a seal ring for sealing the coolant in such a manner as to press the thin film, wherein the coolant can be obliquely injected, either downward or upward. The mandrel is useful for rapidly cooling the tubular thin film in a stable manner.

Abstract: A solid polymer fuel cell electric power generation system (10) removes a substantial portion of water accumulated at the cathode in the outlet fuel stream (18) of the anode. The system permits the operation of a hydrogen/oxygen fuel cell (1) in a deadended mode where substantially pure oxygen is employed as the oxidant supply (54) or using low oxygen stoichiometry where a dilute oxidant source, such as oxygen-containing air, is employed as the oxidant supply. The supply system thereby eliminates the need for an oxygen recirculation pump in systems operating on substantially pure oxygen, and substantially reduces the parasitic load to pressurize the oxidant stream in systems operating on dilute oxidant streams.

Title: Electronically controlled beverage dispenser
Inventor: BETHUY TIMOTHY W
IPC: B67D1/00
Filed: 1995-05-01
Granted: 2005-07-05
Abstract: An electronic control for the operation of a beverage dispenser of the refrigerated ice bank type is shown. The control provides for reliable determinations of when ice production is needed and when it is not needed. A microprocessor receives information from an ice bank probe and from a temperature probe located within the ice bank. Data collected by the microprocessor from both the ice bank probe and the temperature probe is used to determine if the ice bank is either insufficient in size and should be increased or is of sufficient size such that the compressor can be turned off. A carbonator level probe is also shown and connected to the microprocessor. The microprocessor is programmed whereby the carbonator probes are sampled in a manner to accurately determine the level of water in the carbonator and therefore the need for turning on or turning off any water pump connected thereto Both the operation of the compressor and the water pump are controlled by the microprocessor wherein the programming thereof provides for adequate hysteresis protection so that short cycling of the compressor and water pump is avoided.

Abstract: A method is provided for processing seismic data samples obtained from seismic signals propagating in an anisotropic medium. The data samples are associated with scattering angles and azimuth at each migration dip at each image point of the medium. An inverse operator is then applied to the samples so as to provide intermediate anisotropic elastic parameter combinations for each migration dip at each point of the medium. The inverse operator comprises an inverse of a scattering function for variations in elastic parameters from a reference medium against scattering angle and migration dip. The intermediate anisotropic elastic parameter combinations are then migrated to their proper locations.

Abstract: A portable electronic test instrument is adapted for the automatic testing of semiconductor diodes regardless of the orientation of the diode relative to the test probes. The test instrument supplies an a.c. sine wave test voltage coupled to the test probes. The maximum negative voltage and the maximum positive voltage are measured and compared against a set of predetermined open and short circuit values to obtain a decision of open, short, or ok for each value. The combination of the two comparisons is used to determine the device status according to a decision criteria. The diode status is accordingly displayed on the graphical display of the test instrument, indicating the device is open, shorted, a diode with a forward orientation or a reverse orientation with respect to the test probes, or of an unknown type. The diode forward bias junction voltage is displayed regardless of its orientation.
