Patent CA-1278204-C (CA)
Title: Optical fiber connector
Inventor: MORIMOTO YOSHITAKA
IPC: G02B6/42
Filed: 1985-10-07
Granted: 1990-12-27
Abstract: ABSTRACT         An optical fiber connector comprises an internal member and an external member.  The internal member includes a block having a hole which receives a sheath portion at an end of the optical fiber cord as well as an optical fiber exposed from the sheath portion axially.  Cantilevers are pro-vided on side walls of the block to extend along the side walls and have in-wardly protruding projections as well as projections protruding outward when no force is applied.  The external member has an opening through which the optical fiber cord is inserted and openings or recesses which engage with the projections on the cantilever of the internal member on the side walls thereof to be fit into the block of the internal member axially and slidably.  The optical fiber connector of this invention is characterized in that as the internal member is being inserted, the projections of the cantilevers are pressed by the internal wall of the external member so that the cantilevers are deflected inwardly to reach a position to securely hold the optical fiber cord therebetween.  The external member is prevented from receding by the projec-tions protruding from said openings or recesses.

Title: Method of emptying a barge of fish and a barge for use in the performance of the method
Inventor: MALMBAK-KJELDSEN KURT
IPC: A01K63/02
Filed: 1986-04-11
Granted: 1990-11-06
Abstract: Abstract To transfer fry from tanks in a barge to breeding cages immersed wholly or partly in water, use is made of a scraper means consisting of a frame in which a wire net is stretched.  The frame is journalled so as to be pivotable about a preferably fixed axis from a vertical to a substantially horizontal position so that all the fish are lifted to the level of the upper edge of the barge hull where a hopper mounted on a hose is placed.  The other end of the hose is passed down into a cage, and the fish are then flushed through the hose down into the cage by means of a strong stream of water which is passed into the hopper from a pump.  Both the net frame and the hopper may be moved from one tank to another.  The tank-defining part of the barge hull is preferably quater-circular in cross-section.

Title: Homogenising and metering the flow of a multiphase mixture of fluids
Inventor: HUNT ANDREW
IPC: E21B47/10
Filed: 1987-02-20
Granted: 1992-04-07
Abstract: A B S T R A C T         HOMOGENISING AND METERING THE FLOW OF A MULTIPHASE                 MIXTURE OF FLUIDS      It is often desirable to meter multiphase fluid flow in pipes (e.g. bore holes).  In order to obtain reliable/accurate flow rate measurements it is known to incorporate obstructions in the flow path to cause homogenisation.  A non-obstructive method of homogenising the flow of a multiphase mixture of fluids in a bore hole comprises providing in the bore hole a pipe section which has an internal surface with a step discontinuity, whereby when fluid flows through the pipe section, turbulent stresses are caused by the discontinuity, leading to homogenisation by turbulent mixing.  There is disclosed a flow meter which comprises a pipe length with a first section having a step change in cross-section for homogenising fluid flow therethrough, in series with a venturi flow meter in which a differential pressure can be measured in a second pipe section having a smooth change in cross-section.  Non-obstructive homogenisers and flow meters do not block the passage of objects such as tools, logging devices, etc along a pipe.

Granted: 1991-11-19
Abstract: INTEGRATED NMOS-CIRCUIT ARRANGEMENTS:          ABSTRACT:    The integrated NMOS-circuit arrangement is suitable for the connection of an external capacitor (C) in a voltage-controlled oscillator (VCO), whose frequency in the modulation range is linearly-dependent upon the control voltage (Ust) and whose sensitivity in the modulation range is independent of the control voltage (Ust). A switchable charging current source (11; M9) charges the capacitor (C) in a constant period of time at all working frequencies, and a switchable discharge current source (12; M4 to M8, M10, M11, R1) discharges the capacitor (C) in a time which is dependent upon the control voltage (Ust). The switch-over point is determined by a Schmitt trigger stage with inverter (ST), which is fed-back to the current sources. Compensation is provided for fluctuations in temperature and supply voltage (TK).

Title: Method for reduction of sulfur products from flue gases by injection of powdered alkali sorbent at intermediate temperatures
Inventor: MCELROY MICHAEL W
IPC: B01D53/34
Filed: 1987-05-12
Granted: 1992-12-01
Abstract: ABSTRACT OF THE DISCLOSURE            A method is provided for reducing the sulfur content of exhaust  (flue)  gas  from  a  combustion  installation manufacturing process, or chemical process comprising the step of  injecting   dry powder alkali hydrate sorbent directly into intermediate temperature  (800° - 1200°F) combustion/process  gases.   The alkali  hydrate  sorbent reacts rapidly with the sulfur-containing gases in this temperature  regime   to   produce   primarily   alkali sulfites.   The unreacted portion of the sorbent largely remains in the form of an alkali hydrate and may react further with residual sulfur, especially in the presence of water,  at  lower  temperatures.   A novel  combustion chamber is also provided having an injection means for injecting alkali hydrate sorbent into a combustion volume where the temperature is in the range of 800° - 1200°F, to cause a predetermined reaction of the alkali hydrate sorbent with  SO2 and  the combustion gases to produce primarily  alkali  sulfites  with  the  unreacted  sorbent remaining substantially as alkali hydroxide.

Granted: 1991-01-15
Abstract: ABSTRACT            AN OPTICALLY CONTROLLED SELECTOR      An optically controlled selector comprises an optical coupler (1) having a first input (2) for an optical input signal, a second input (3) for an optical control signal and an output (4) for a combined signal, and a resonant cavity (5) downstream of the output of the coupler (1) and arranged to receive the combined signal.          The resonant cavity (5) contains an optically non-linear material so that changes in the power of the optical control signal result in changes in the resonant frequency of the cavity (5).  In use, the power of the optical control signal controls the transmission or suppression of the optical input signal through the optical cavity.  Such a selector acts as a simple switch or to select one from a number of optical signals of different wavelength.          Preferably the optical material is active and the optical cavity (5) formed by a semiconductor laser amplifier.

Title: Process of treating a pressurized laden absorbent solution
Inventor: GRUENEWALD GERHARD
IPC: B01D53/14
Filed: 1988-03-25
Granted: 1992-08-11
Abstract: ABSTRACT              A gas which contains CO2 and at least one of the valuable gases methane, hydrogen or carbon monoxide is purified by means of an absorbent solution in a scrubbing zone under a pressure of at least 5 bars.          The laden absorbent solution has absorbed CO2 and at least one of the valuable gases by physical dissolution.          For a recovery of the valuable gas or gases, the laden absorbent solution is pressure-relieved to an interme-diate pressure in a stripping zone and is stripped in said stripping zone with a gas which predominantly con-sists of CO2. A gas mixture which contains a valuable gas is withdrawn from said stripping zone. The absorbent solution is pressure-relieved further in a succeeding pressure relief zone, from which a flashed-off gas con-sisting predominantly of CO2 is withdrawn. The laden absorbent solution is pressure-relieved to a first intermediate pressure in a pressure relief zone which precedes the stripping zone and the laden absorbent solution is then supplied to the stripping zone. The gas which has been flashed off in the succeeding pressure relief zone may be fed to the stripping zone as a strip-ping gas.
