Inventor: OVERTON DENNIS LLEWELLYN
IPC: F23C7/00
Filed: 1996-03-22
Abstract: A combustion chamber head assembly consists of an annular, domed combustor head separated on its downstream side from the combustion region by an annular bulkhead.  A number of fuel injector means are spaced apart around the head assembly and extend through to supply fuel-air mixture to the combustor region through apertures in the bulkhead. Fuel is supplied by a nozzle at the upstream end of a mixing region.  Air is admitted to this region through a variable geometry airflow arrangement comprising several airflow passage disposed concentrically around the nozzle, the passages may include swirl vanes.  A portion of the wall surrounding the mixing region is axially translatable to close-off one of the air inlet passages and direct air from the mixing region into the cavity enclosed by the combustor head and bulkhead from where it escapes into the combustion region through air-only apertures in the bulkhead wall.

Inventor: FLOCKHART ANDREW DEREK
IPC: H04M3/523
Filed: 1996-04-25
Abstract: An improved method and apparatus (12) for handling calls in a call center (FIG. 1) predicts (206, 312, 410) a caller's level of motivation for making the call and uses (208-212, 314-330, 412-416) the prediction as a basis for determining how to handle the call. The method and apparatus respond to a call coming in to the call center by determining (206, 306, 404) a number of call attempts -- either all call attempts whether answered or unanswered by an agent, or only unanswered call attempts -- made by the caller to the call center within a predetermined elapsedperiod of time, and possibly also by determining (308-310, 406) other predictors of the level of motivation of the caller in making the call, prior to the call being answered. Based upon the determined number of call attempts and the other predictors of the caller's motivation level, the method and apparatus then select and give (208-212, 314-330, 412-416) to the call one of a plurality of different treatments that could possibly be given to the call -- for example, they select a split to which the call should be queued and/or a priority level for queuing the call. Preferably, the selected treatment is given to the call before an agent of the call center answers the call.

Title: A brake control device for railroad cars
Inventor: DOTO SHIGEAKI
IPC: B60T13/66
Filed: 1996-07-17
Abstract: A brake control device for railroad cars in which a high level priority part selects the high-level signal of such individual supplementary hydraulic brake signals based on such electrical brake power signals of each axle or truck unit and communicates it as input to such electro-hydraulic convertor part.  Such electro-hydraulic convertor part communicates such supplementary hydraulic brake power signal as input directly to such high-level brake cylinders and performs reduced pressure adjustment of such hydraulic brake power according to such low-level individual supplementary hydraulic brake signals at such slip prevention valves in communicating such signal as input to such low-level brake cylinders.  Thus it is possible to share the brake system equipment from such electro-hydraulic convertor part up to such slip prevention valves, and allow such supplementary hydraulic brake power to be controlled in axle or truck units with the same simple configuration as existing cars.  In this way, it becomes possible to control the brake power of truck units or axle units without suffering increases in the number of components or the amount of maintenance, or losses in reliability.

Abstract: A filter (10) is provided comprising a first filter layer (12) made of TiO2 or Ti4O7 particles deposited on a second filter layer (14) by stainless steel particles. The first layer (12) has a smaller pore size than the second layer (14). The construction of the filter (10), the relative thicknesses of the layers (12, 14) and the resistance thereof to movement therethrough of electrolytically generated gas located between the two layers (12, 14) when the filter (10) is permeated with liquid being such that such gas reaches the upstream side of the filter before the downstream side. Thus in one embodiment stainless steel particles are sintered and rolled with a textured roller before ceramic particles are applied and rolled. An intermediate layer of metal particle peaks and ceramic filled troughs is thus provided which has high tortuosity. The resistance to flow at the metal/ceramic interface can be increased by electrodeposition of metal there.
