Title: Pressure transmitter with flame isolating plug
Inventor: WALISH JAMES E
IPC: G01L9/00
Filed: 1990-07-31
Abstract: ABSTRACT OF THE DISCLOSURE       A transmitter (10) that provides an output indicating pressure difference between a line pressure and atmosphere outside the transmitter (10) is made intrinsically safe by coupling the sensor cavity (44) as well as other cavities (12, 13) where ignition can occur to atmosphere only through flame quenching paths.   The opening (22) in the transmitter housing (10) in which the sensor (45) is mounted has a plug (41) including the sensor cavity (44) that holds the sensor (45), and a fitting (26) which is couplable to the pressure line.  An isolator (35) is used for transmitted the process pressure to the sensor (45) through an isolator diaphragm (35A) acting on an incompressible filling the sensor cavity (44) and transmitting pressure through a passageway (35B) that is shaped to provide a flame quenching path.  The passageway (35B) flame isolates the sensor (45) from the process fluid line.  The opposite side of the sensor (45) is connected to atmosphere only through paths (50, 51, 52) which are flame quenching because of the passageway shape.  The plug (35) is an assembly that can be made easily inserted and removed, and provides intrinsic safety even if there is failure of some of the components such as the isolating diaphragm (35A) or welds holding portions of the plug (35) together.

Abstract: Described is a method and apparatus useful in the course of a milking operation in which the milk is intermittently conveyed in the form of separate milk slugs, to accurately determine the mass of the individual milk slugs and to thereby determine the actual milk flow rate. A measuring apparatus of this type is particularly suitable for use as an indicator operable to indicate the drop of the milk flow to below a predetermined value at the end of a milking cycle. An additional operation of measuring the travel speed of the individual milk slugs results in an extremely simple milk flow measuring device being obtained, which is capable of relatively accurately measuring the milk flow rate throughout the milking cycle.

Patent CA-2065549-A1 (CA)
Inventor: HARDISON LESLIE C
IPC: B01D53/34
Filed: 1992-04-07
Abstract: An apparatus and method of contacting a liquid with different gases sequentially in separate mass transfer zones within a single vessel, the mass transfer zones operatively connected in liquid communication with each other, including intimately contacting the liquid with a first process gas in cocurrent flow in a first mass transfer zone to effect mass transfer between the first liquid and the process gas, and introducing the liquid into a second mass transfer zone with a second gas, different from the first gas, in cocurrent flow with the second liquid, thereby effecting mass transfer between the second liquid and the second gas. The rate of flow of the liquid from said first mass transfer zone to second mass transfer zone and recirculation to the first mass transfer zone is motivated by the difference in density of the contents of the liquid phase portion of each mass transfer zone and a following liquid downcomer or flow channel connecting it to the next sequential mass transfer zone, such that after passing through the last mass transfer zone, the liquid recirculates to the first mass transfer zone. The apparatus and method are ideally suited to carrying out the process of hydrogen sulfide removal from gases by means of an air-regenerated liquid redox catalyst, such as chelated iron. <IMAGE>

Patent CA-2076327-A1 (CA)
Inventor: ESTES BAY E
IPC: H01H47/00
Filed: 1992-08-18
Abstract: ABSTRACT       A controller for a relay (R) controls the pull-in time of the armature of the relay by controlling the power applied to the relay coil (1).  To determine the actual pull-in time, the time of closure of the contacts is sensed (37, 39) and the time at which power is applied to the coil (6) is subtracted from it (38). The actual pull-in time (at 40) is then compared (42) with a stored value (at 44) of ideal pull-in time to produce an error signal (46).  The error signal corrects (14, 13) the level of power applied to the relay coil upon the next actuation of the relay, to make the actual pull-in time approximately equal to the ideal pull in time.  In some embodiments, to control the level of power on the coil, a Grey-code counter (20) samples a duty-cycle register (14) in a micro-computer (4'') and produces a train of pulses (at 8'') that is filtered (53'', 55'') to provide a DC control signal (51''). The DC control signal controls the duty cycle of a pulse-width-modulated oscillator (9) that rapidly switches (modulates) the power to the relay

Title: Combustion engine of the piston engine type
Inventor: WELLEV JENS ERIK
IPC: F02B75/18
Filed: 1991-03-15
Abstract: A combustion engine (1) of the piston engine type where the static compression ratio exceeds approximately 15:1, especially in the range of from approximately 15:1 to approximately 20:1, preferably approximately 17:1. The engine is provided with an ignition system (3) where the ignition point is situated after the top dead center (TDC), especially in the range of from approximately 0·  TDC to approximately 20· TDC, preferably approximately 4· TDC. As a result, it is possible to achieve an ignition of a fuel, the spontaneous ignition capacity of which at the predetermined compression ratio does not usually suffice. The resulting ignition generates a maximum pressure in the cylinder of approximately 90· TDC, whereby a high efficiency of the fuel is obtained without simultaneously involving a steep increase in the temperature in the combustion chamber. A Venturi (71) for the combustion engine (1) according to the invention is substantially axially symmetrical when seen in the flow direction. The Venturi comprises a mixing chamber, an inlet side of an annular, slot-forming ring, an outlet side of the annular, slot-forming ring and a transition portion (77) to the inlet manifold (11).
