Inventor: STANISLAV FEDOROVICH KOZLOV
IPC: G01T3/08
Filed: 1969-10-09
Abstract: Detector system has a plate of material which, gives off ionizing radiations under neutron bombardment which fall in turn on a crystalline diamond plate with a barrier layer to charge carriers on its front face and a charge carrier injection electrode on its rear face. The barrier layer is an electrode and is connected to an amplier-recorder whilst a current source is connected via a resistor to the charge carrier injector. The thickness of the diamond plate is no greater than the maximum drift of charge carriers, during their life time, under the influence of that electric field which produces maximum drift velocity.

Title: Air outlet nozzle
Inventor: VUORIMAA PEKKA
IPC: F24F13/06
Filed: 2000-03-10
Abstract: An air outlet nozzle 10 comprises a body part 12 having a circular cross section, one edge of the body part having a lid-like lip portion 13 attached thereto, and a partition 14 which divides the bore of the body part 12 into channels A<SB>1</SB> and A<SB>2</SB>. The partition 14 has a curved shape which serves to guide the air flow out from the channels A<SB>1</SB> and A<SB>2</SB> at an oblique angle. The lip portion 13 assists the redirection of the air flow by partially covering the opening of channel A<SB>2</SB>. The nozzle may be fixed to a panel element allowing rotation about its centre axis, and the partition may be made as a bimetallic element or from a memory metal, thereby allowing thermal control of the air flow through the nozzle. The position of the partition 14 may be adjustable with respect to the body part 12.

Title: Telecomms tariff system
Inventor: TRINH PHU
IPC: H04M15/00
Filed: 2000-09-01
Abstract: A telephone network has both contract and pre-paid customers and several different loyalty schemes (e.g. a scheme providing contract customers with bundles of call time for which separate call charges are not made, roll-over of unused bundled call time into the next charging period, reduced charging rates for calls to particular pre-selected numbers etc). In response to an incoming call, step C first determines whether the customer is a contract or a pre-paid customer. If a pre-paid customer, step D determines whether or not the call is to one of the pre-selected numbers in a nominated-number group. If so, the customer's pre-paid credit is decremented at a reduced rate; if not, it is decremented at a standard rate. If a contract customer, step H determines whether the call is to one of the pre-selected numbers. If not, step I determines whether the call can be decremented to a bundle or not. If so, it is decremented to the bundle (step J) and a charge is only applied if its length exceeds the remaining bundle time. If it is not eligible to be charged against the bundle, it is charged at a standard rate (step N). If the call is determined to be to one of the pre-selected numbers, again (step O) a determination is made whether the call can or cannot be charged to a bundle. If it can be charged to a bundle (step Q) it is charged at a reduced rate.

Title: Method of managing circular buffers in dynamic bandwidth circuit emulation services
Inventor: FINN DAWN
IPC: H04L12/70
Filed: 2000-09-13
Abstract: In a method of managing buffers in a SAR (Segmentation and Reassembly) device operating in DBCES (Dynamic Bandwidth Circuit Emulation Service) mode, first an active channel buffer limit is determined. This is dependent on the number of active channels in the virtual circuit. Next, the amount of buffering for each active channel is set equal to the CDV (Cell Delay Variation) plus the active channel buffer limit. This prevents underruns over overruns from occurring when the number of active channels suddenly changes.
