Title: Method of distributing a fluid in the fluid bed of a fluid bed reactor
Inventor: NIELSEN CLAUS SCHAFER
IPC: B01J47/10
Filed: 1991-07-08
Abstract: A method of distributing a liquid in the fluid bed of a down-flow fluid bed reactor having a vertical reactor with an inlet, an outlet, and fluid bed particles suspended in the liquid, the method comprising the steps of agitating the particles and liquid proximal to the liquid inlet so as to divide  the  fluid bed into a  turbulent  zone having vigorously moving particles, and a non-turbulent zone, the non-turbulent  zone  adjoining  the  turbulent  zone,  and selecting a degree of agitation within the range from a degree  of  agitation  providing  turbulence  only  in  the uppermost part of the fluid bed to a degree of agitation providing turbulence of the particles throughout the fluid bed is employed to determine the extent of said turbulent zone.

Abstract: A telescoping weir for the controlled drainage of contaminated bodies of water, such as confined disposal facilities (CDF), which selectively releases only the relatively clean water while leaving behind a contaminated portion. The weir includes a foundation that is anchored to the bottom of the body of water and connected with a discharge pipe, a cylindrical telescoping portion connected with the discharge pipe and extending upwardly from the foundation and terminating adjacent to the surface of the body of water, and a set of mechanical jacks for selectively extending and retracting the upper end of the telescoping portion above and below the water surface in order to selectively drain a top layer of clean decant water therefrom.

Title: Crossing assembly for point switches and processing
Inventor: LOCHSCHMIDT OSWALD
IPC: E01B7/12
Filed: 1997-08-21
Abstract: The rigid frog for switch points and crossings with two wing rails (1, 2) and a frog point (3, 6, 4, 5) arranged therebetween, which forms with the wing rails switch openings (11) that run at an acute angle relative to each other, is characterized in that the frog point and the wing rails are elastically joined by anchor clamps on each foot side to ribbed plates (247-253). The previous unit of a rigid frog with wing rails and HB bolted point is thus resolved to individual rails. The individual rails each have their own intrinsic elasticity so that the frog behaves like a normal rail in the track in terms of oscillation and damping behavior. The previously used filling plates are no longer required. Beneath the rails are plates with which a height adjustment, especially of the wing rails (1, 2), can be effected, so that wear of the traversed surface of the wing rails can be compensated for in terms of height by changing the thickness of the spacers. The spacers (42, 43) can be elastic. Transverse to the longitudinal axis of the rails, the rail parts are secured essentially without play by ribs (39, 39a, 39b, 40, 41). In order to rule out longitudinal shifting of the point relative to the two wing rails, a correspondingly designed rail anchor is arranged in the region of the wing rail ends (Figure 1).

Abstract: The invention describes multiphase lubricant concentrates with enhanced properties to be used in acqueous working fluids from exploratory drilling of soil, containing liquid or solid organic constituents at room temperature with a lubricating effect (O-phase) in addition to emulsifiers which are finely dispersed in a closed aqueous phase (W-phase). The concentrates are characterized by the fact that the system consisting of an oil phase, a water phase and emulsifiers has a phase inversion temperature (PIT) above room temperature and is produced by heating the multiphase system to temperatures equal to/above the PIT and subsequently cooled to smaller PIT values. The invention also relates to the use of such multiphase lubricant concentrates as an additive to water based working fluids in the field of exploratory drilling of soil and further treatment of such drilling.

Patent CA-2275644-A1 (CA)
Title: Pipeline analog-to-digital conversion
Inventor: STENSTROEM HELGE
IPC: H03M1/06
Filed: 1997-12-05
Abstract: Pipeline A/D-conversion of an analog input signal is performed according to a new and inventive algorithm which generates a Gray coded digital output signal. A pipeline A/D-converter comprises a number of cascaded stages through which the analog input signal is propagated. Each stage generally generates an output bit of the digital output signal, and furthermore processes the pipeline signal. According to the inventive Gray coding algorithm, the output bit generated in a stage determines whether or not the pipeline signal of that stage is inverted. In a pipeling A/D-converter based on the Gray coding algorithm according to the invention, the accumulation of offset errors will generally be very low. Furthermore, the fact that the signal inversion is digitally controlled enables high precision implementations which further improve the performance of the inventive pipeline A/D-converter. In another embodiment of the invention, the Gray coding algorithm is modified to form a second algorithm which makes low device count implementations possible.

Title: Valves for packaging containers
Inventor: RAMSEY CHRISTOPHER PAUL
IPC: B65D47/20
Filed: 1998-07-27
Abstract: A self-closing valve for a packaging container, especially a thin-walled plastics bottle, has an outwardly concave valve head (22) joined to an outer margin (20) by a flexible connecting wall (24). The connecting wall has a frustoconical outer portion (56) and a cylindrical inner portion (57) joined together at an elbow (58). The inner portion (50) is joined to the valve head at a thin, inturned flange (60). The outer portion (56) of the connecting wall is frustoconical and moves between downwardly inclined and upwardly inclined positions as the valve advances to its dispensing position. It accordingly imparts a bistable operating characteristic to the valve. The elbow of the connecting wall acts as a spring to retract the valve head quickly after dispensing. The flange (60) acts as a living hinge, with substantially no flexural stiffness, so that subsequent deformation of the valve head to allow venting is not resisted.

Title: Dynamic buffering system having integrated random early detection
Inventor: BONNEAU MARIE-CLAUDE
IPC: H04L47/32
Filed: 2000-01-31
Abstract: The method of buffering packets in a digital communications device includes defining an n-level hierarchy of memory partitions, wherein each non-top level partition has one or more child partitions at an immediately lower level of the hierarchy. The memory partitions at the top-most level are pre-configured with a target memory occupancy size, and the target occupancy for each memory partition situated at a lower level is recursively computed in a dynamic manner based on the aggregate congestion of its parent partition, until the target occupancies for the bottom-most memory partitions are determined. Each traffic flow which uses the buffer is associated with one of the memory partitions at the bottom-most level of the hierarchy and packet discard is enabled in the event the actual memory occupancy of a traffic flow exceeds its target occupancy. The memory partitions at higher levels are preferably associated with a set of traffic flows, such as traffic flows associated with a particular egress port and class of service, to thereby selectively control aggregate congestion. Traffic flow sets may be also be defined in respect of adaptive flows such as TCP flows which decrease their transmission rates in response to congestion notification, and non-adaptive flows such as UDP flows which do not decrease their transmission rates. Random early detection (RED) is applied to such traffic flows based on the target occupancy of the corresponding memory partition. The method is expected to improve network performance, allow full buffer sharing, permit the weighted distribution of buffer space within a memory partition, and scale easily to large systems.
