Title: Material drying or processing method and apparatus comprising a venturi
Inventor: STUBBING THOMAS JOHN
IPC: F26B17/10
Filed: 2008-11-13
Abstract: A method of drying or processing materials in a drying or processing cylinder, or other drying or processing apparatus, located within or forming at least part of an enclosure 1. At least a portion of a process gas entering a higher pressure region 4 of the enclosure is routed by a fan 2 through a venturi and around, over, across, through or adjacent the open end of a material input tube 7 at increased speed and reduced pressure. This provides suction at the opening of the material input tube into the higher pressure region of the enclosure which is sufficient to prevent, or substantially prevent, the pressure at the higher pressure region of the enclosure causing the process gas atmosphere in the enclosure to be blown through the tube and out of the enclosure into the external air or other gas atmosphere outside the apparatus. Preferably, the venturi is defined by an annulus formed by the material input tube located coaxially within a process gas duct 6, 8. The speed of the fan may be controlled. In a further aspect, an associated apparatus is disclosed.

Title: Automatic configuration of synchronous block execution for control modules in Fieldbus networks
Inventor: ENVER ALPER T
IPC: G05B19/042
Filed: 2008-12-18
Abstract: A process control module 50 is automatically configured for synchronous execution on a Fieldbus segment 56 of a process control network (10). It is determined if input function block 52 and output function block 51 of control module 50 are assigned to Foundation (RTM) Fieldbus field devices 54, 55. If so, intermediate function block 53 (e.g. a PID block) is automatically assigned for execution to a fieldbus port 59 of an input/output (I/O) device 58 (e.g. a fieldbus card) associated with Fieldbus segment 56. Thus, function blocks of the control module, which would otherwise be scheduled to execute in a process controller 57, are assigned to the I/O device 58. This enables all of the critical function blocks within the control module to execute in one macrocycle of the Fieldbus segment, thereby executing synchronously on a Fieldbus segment. Thus, the overall execution rate of the control module is increased compared to the traditional split of function blocks between a controller and field devices on a Fieldbus segment.

Abstract: 493,622. Valve circuits for wireless reception. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. April 13, 1937, No. 10510. Convention date, April 13, 1936. [Class 40 (v)] In an electron coupled frequency changer a path is provided between the signal grid and local oscillator for applying to the signal grid out of phase local oscillations to reduce the effect of second and higher order demodulation products causing interference. Fig. 3 shows a valve 1 with the signal applied to the control grid 6 adjacent the cathode and the local oscillation applied to the grid 7 and also through condenser 10 and to the grid 6. In a modification, Fig. 2 (not shown), the signal is applied to the grid 7 and the local oscillation to the grid 6 adjacent the cathode and also to the grid 7. The auxiliary coupling of the local oscillator may be magnetic, Fig. 4 (not shown), or by a condenser common to the signal and oscillator tuned circuit, Fig. 5 (not shown), or by magnetic coupling to the cathode lead, Fig. 6 (not shown). Fig. 7 shows a separate local oscillator coupled to the grid 7 and through a phase inverting valve 21 to the grid 6 to which the signal is applied. The cancellation voltage for the second and higher order demodulation products is varied by the application of automatic volume control to the frequency changer. This variation is compensated by varying the mutual conductance of the phase inverter 21 in the opposite sense by grid bias control through resistance 23 from the potentiometer 25, 26 in the screen circuit of the valve 1. In a modification, Fig. 8 (not shown), the automatic gain control voltage is applied to both signal and oscillator grids, when, if the oscillator grid draws little current the two grids will vary in the same sense but at different rates, the grid next to the cathode to which the signal is applied varying less than the grid to which the local oscillation is applied. Specification 454,996 is referred to.
