Abstract: ABSTRACT OF THE DISCLOSURE       A method is provided for the control of servo hydraulic pressure in an automatic transmission. Servo hydraulic pressure is adapted to engage or release first and second frictional engagement elements ar-ranged in such a relationship that upon shifting from a particular speed stage to another, one of the first and second frictional engagement elements is released while the other is engaged. The servo hydraulic pressure is linearly lowered in a torque phase during a shift so that the servo hydraulic pressure on a side of the frictional engagement element to be released by using as an input the servo hydraulic pressure on a side of the frictional engagement element to be engaged is maintained in conformity with an inversely proportional relationship between engaging pressure and drain pres-sure.

Abstract: A process for the removal of sulphur compounds from a gaseous effluent, comprising the steps of: a), contacting the gaseous effluent-with an aqueous solution wherein sulphur compounds are dissolved: b) adjusting the concentration of buffering compounds such as carbonate and/or bicarbonate and/or phosphate in the aqueous solution to a value between 20 and 2000 meq/l; c) subjecting the aqueous solution containing sulphide to sulphide-oxidising bacteria in the presence of oxygen in a reactor wherein sulphide is oxidised to elemental sulphur; d) separating elemental sulphur from the aqueous solution; and e) recycling the aqueous solution to step a). This process is suitable for removing H2S from biogas, ventilation air etc. It can be used for removing SO2 from combustion gases by introducing the additional step, after step a) and before step c), of subjecting the aqueous solution containing the sulphur compounds to a reduction of the sulphur compounds to sulphide. H2S and SO2 removal is further enhanced by a residual sulphur content in the washing liquid of 1-50 g/l.

Title: Stream selector for process analyzer
Inventor: MAYEAUX DONALD P
IPC: G01N1/16
Filed: 1993-08-09
Abstract: ABSTRACT OF THE DISCLOSURE A stream selector for a process analyzer.  In one aspect the invention provides a valve module for a process analyzer.  The module includes a first block valve having a first opening, a second block valve having a second opening, and a bleed valve having a third opening.  The first and second block valves are made so that both are closed or both open at the same time.  The block valves and the bleed valve are made so that, in a first mode, the block valves are closed and the bleed valve is open; in a second mode, the block valves are open and the bleed valve is closed; and in a third mode, all of the valves are open, thereby ensuring that the module is completely purged.  In a second aspect the invention provides a stream-selection valve manifold. The manifold is made by joining two or more valve modules side by side to form a common outlet passageway and a common vent passageway, thereby ensuring that the manifold is completely purged.  In a third aspect the invention provides a single block-and-bleed valve module.  The module includes a block valve, a sample-fluid compartment, a vent compartment, an internal pneumatic actuator, an actuator compartment, a sample-inlet first passageway, a sample-outlet second passageway, a third passageway for introducing a compressed gas into the actuator compartment, a fluid-disposal fourth passageway, a spring for closing the block valve, a compressed gas for opening the valve, and a body for containing the modular components.  The disposal passageway provides fluid communication between the vent compartment and an external area suitable for the safe disposal of sample fluids and compressed gas contained in the valve module.  The pressure within the vent compartment and the disposal passageway is normally kept equal to or lower than that of the sample-inlet passageway, sample-outlet passageway, and actuator compartment, in order to prevent fugitive emission of the sample fluid or the compressed gas from the module into the external environment.  The flat-face sealing structure of each valve is very tolerant of scratching and/or irregularities in the sealing structure and of abrasive particulates which may be present in the sample fluid, and even to minor structural damage to the sealing structure.

Title: Time-division multiplex communication transmission apparatus
Inventor: SHIMIZU HIROYUKI
IPC: H04J3/10
Filed: 1994-01-25
Abstract: A time-division multiplex communication transmission apparatus includes a logic processing circuit, a digital filter, a modulation circuit, and a high-frequency amplification unit.  The logic processing circuit performs logic processing of input burst data and outputs a burst timing signal for each time slot for time-division transmission.  The digital filter converts output data from the logic processing circuit into baseband data for modulation.  The digital filter is reset at a time slot boundary when no burst data signal is present in an adjacent time slot.  The modulation circuit modulates an output signal from the digital filter.  The high-frequency amplification unit performs burst waveform processing of an output signal from the modulation circuit on the basis of a burst timing signal from the logic processing circuit.

Title: Sheave cleaning tool
Inventor: MACLEAN IAN A
IPC: B66B7/12
Filed: 1994-02-18
Abstract: My device relates to a device to clean sheaves, such as those used in the operation of elevators. A particular application of my device is as a sheave cleaning tool.     The present invention, the sheave cleaning tool, comprises of a mounting plate and a blade plate attached by a hinge. A handle is welded to the blade plate to enable the the operator to raise and lower the blade, altering the level of pressure of the blade, applied to the sheave, without the operator having any contact with the blade or sheave. When this pressure is applied, the blade is lowered into the groove of the sheave, cutting and scraping away hardened rope tar that has been packed into the grooves of the sheave which guide the cables around the sheave. The blade itself is cylindrical and cut on an angle to form a point which fits into the grooves of the sheave. A cloth attachment may be fitted over the blade to apply cleaning solutions after the device has been used to remove hardened rope tar from the grooves of the sheave.     The present invention has three safety features which may be added. The first safety feature consists of a threaded rod which is attached to the adjustable mounting plate, runs through the blade plate and is bolted on the underside of the blade plate. The second safety feature consists of a spring-back mechanism which automatically retracts the blade when not in operation. The third safety feature may be added to the design of the blade itself. The blade may be designed to pivot and lock to ensure the retraction of the blade during reverse movement of the sheave.
