Title: Frequency allocation communication process and network
Inventor: AUDOUIN OLIVIER
IPC: H04B10/572
Filed: 1992-01-23
Abstract: Communications are carried out, as known, between terminals in the form of informational modulations applied to transmission waves which travel over common transmission lines (62). One transmission frequency (F(2P-1)) is allotted to each terminal (T1) for each communication. According to the invention, all the terminals (T1,...TN) are furnished with a marker wave (FM1) by which a transmission frequency is marked whilst no communication is yet being set up. When a new communication is set up, the marked frequency is allotted in respect of this new communication to at least one of the terminals which are to participate therein.

Abstract: A multi-stage, batch or continuous, manual or automated process and apparatus (1) for safely depressurizing, de-capping, and recycling aerosol cans (11), propellants, solvents, chemicals, dip tubes, and can tops (43). The apparatus includes a sorting and loading unit (2) for guiding the cans onto an advancing line (10). The cans are first depressurized by a vacuum head unit (3) comprising a vacuum seal and a reciprocable hollow needle (70) which punctures the top cap and removes the propellants by suction. The cans are advanced to a decapping unit (4) where the cap member is removed by decrimping. The decrimper/decapper head includes a plurality of specially adapted pincers (80) for gripping and radially inwardly deforming the cap nozzle neck. The method includes unloading cans bottom side down, passing them at preselected, indexed intervals and rate along a disassembly line for depressurization, removal and recovery of propellants, and decapping. The can top, plastic dip tube assemblies, and residual solvents and chemical contents are recovered for disposal or recycling. The cans are washed, rinsed and dried.

Abstract: A method of detecting conditions during the operation of a transport refrigeration unit (20) which may cause shutdown, and then modifying the operation of the unit in an attempt to find an operating condition that will keep the unit operating safely. the unit includes a compressor (26) driven by an engine (30) operable at low and high speeds. Upon detecting (264) an over-temperature condition of the engine a first modification (282) is initiated, including switching the engine to low speed.      If the engine temperature dogs not drop to a safe value (288; 292), a second modification (296) is initiated. If the engine gas in low speed (280) when the over-temperature condition was detected, the second modification is initiated immediately. Upon detecting (316) a low oil pressure condition, the engine is switched (316) to high speed. If the oil pressure rises to a safe level, engine operation is continued at high speed. Appropriate alarms (326) accompany the modified operating conditions.

The dithio-lenes have the formula shown in Figure I wherein: (A) the R groups, any two of which may be the same or different, are selected so as to tune the absorption bands of the molecule for use at the operational wavelength and/or to act as bridges to join mole-cules together; (B) the X groups, any two of which may be the same or different, are selected from S and Se; (C) M is selected from Ni, Pt, Pd and Cu; (D)C = -1 or 0; and (E) (i) when C = -1, Y is a cation to render the molecule electrically neutral; pref-erably Y is selected from ammonium, substituted ammonium, Na +, Li + and K+,(ii) when C = 0, Y is absent (since the mole-cule is neutral there is no change to balance). The dithiolene may be diluted with an organic polymer selected from polyacry-lates, polymethacrylates, such as polymethymethacrylate, polycarbonates, polyisobutylene, polyethylene terephthalate, po-lystyrene and polysiloxane.

Abstract: An apparatus to determine characteristics of an optical communication path by utilizing electrical devices in an electrical path in parallel with the optical communication path. Each electrical device is physically located with a passive or active optical device and specifies the attenuation and delay of the optical device. A receiver measures the electrical qualities of each electrical device in the electrical path which is parallel to the optical path from the optical transmitter. The electrical measurements allow the receiver to automatically adjust its optical receiver to the attenuation and delay introduced by the optical devices in the optical path.

Filed: 1991-02-15
Abstract: A fully automatic organ pressure sensitive apparatus for dislodging and removing obstructions in body cavities or organs by both delivering (17) and removing (20) fluid thereto, operable by high rate continuous or intermittent infusion of fluid solvent over a set pressure range to effect rapid dissolution and removal of the obstruction without complications to the patient. By continuous feedback monitoring (22) of fluid pressure in the bodily organ or cavity (19) of interest, the apparatus can constantly vary infusion and aspiration rates to maintain the set pressure range. If the pressure persists above or below the set range, the apparatus activates a safety feature (32) leading to a period of maximal aspiration and cessation of infusion, followed by cessation of solvent transfer and triggering of an alarm (34) to alert the operator.

Title: Internally sealable perforable nipple for downhole well applications
Inventor: ROBISON CLARK
IPC: E21B34/14
Filed: 1994-03-28
Abstract: ABSTRACT OF THE DISCLOSURE       A longitudinally spaced series of tubular nipple structures are installed in a well flow conductor operatively extended through a subterranean well bore.  Each nipple structure has a thinned-wall, increased interior diameter longitudinal section through which a plurality of  fluid flow openings laterally extend, and an interior side surface annular tool locator recess, with each such recess having a profile different than those of all  of the other tool  locator recesses.   The thinned-wall longitudinal sections of the nipples facilitate the formation of the flow openings therein.  To seal off the flow openings in any selected one of these longitudinal nipple sections, a radially expandable tubular metal patch is supported on a setting tool which is lowered into the well flow conductor.  A locator member complementarily and lockably receivable by the locator recess of the selected nipple is also supported on the tool.  When the locator member snaps into releasably locked engagement with such locator recess, the patch member is automatically positioned in a predetermined longitudinal orientation coaxially with the longitudinal nipple section whose flow openings are to be sealed off.  An expander portion of the setting tool is then pulled through the patch member to radially expand it into sealing engagement with the  interior  side  surface  of  the  selected longitudinal nipple section.   Due to the increased interior diameter of the longitudinal nipple section, the tubular patch member installed therein does not decrease the drift diameter of the well flow conductor.

Abstract: Disclosed is a circuit for detecting an unrecorded portion in a recording medium, which comprises a window counting portion (10) for receiving an input signal to recognize if the input signal comes from an unrecorded portion of the recording medium and counting a predetermined time to generate a window pulse signal, and a sync signal generator (20) which is enabled by the window pulse signal, in which if the number of pulses of the input signal is not less than a predetermined number, the generator recognizes the current input signal comes from a data region of the recording medium to simultaneously generate a sync signal, while if the number of pulses of the input signal is not more than a predetermined number of pulses, the generator recognizes the current input signal comes from an unrecorded region of the recording medium, not to generate the sync signal. The unrecorded portion is accurately detected not to generate a sync signal due to noise included in the unrecorded portion of the recording medium.
