Title: Plant for heat treatment of lumpy material
Inventor: OLBYE BENDT
IPC: F27B7/20
Filed: 1995-06-01
Abstract: A description is given of a plant for heat treatment of lumpy material, such as lime-stone, other carbonate materi-als, cement raw materials, or the like. The plant comprises a preheating zone (1), a burn-ing zone (3) and connecting means (20) which connect the material outlet (7) of the pre-heating zone to the material in-let (13) of the burning zone. A separating device (21) is pro-vided as a part of the connect-ing means (20) and consists of a duct (21) through which a gas stream can be induced to flow from below and upwards. So, on entry into the separating duct (21) at the top of the duct, the preheated material will be dispersed in the counterflowing gas stream, whereby the mate-rial is divided into a fine frac-tion which suspended in the gas can be discharged via the discharge means (25) provided at the upper end of the duct, and a fall-through coarse frac-tion which in normal manner can be fed via a connecting means (20) to the material inlet (13) of the burning zone.

Title: Methods for measuring telomere length
Inventor: KOZLOWSKI MICHAEL R
IPC: C12Q1/68
Filed: 1996-06-06
Abstract: Methods and compositions for the measurement of telomere length have application in medical diagnostic, prognostic, and therapeutic procedures. The methods for measuring telomere length include primer extension-based methods and probe-based methods. The primer extension methods involve elongation of telomeric, linker, and/or subtelomeric based primers under conditions such that the telomere serves as a template for primer extension and that the resultant primer extension products can be compared to standards of known length to provide a measure of telomere length. The probe based methods allow for telomere length measurements using DNA from lysed or whole cells and involve hydridizing an excess of probe to all telomeric repeat sequences in the telomere, measuring the amount of bound probe, and correlating the amount of bound probe measured with telomere length.

Abstract: A decoder which is adapted to receive a frame of  coded  data consisting  of  multiple  slots  including intra-frame position  information  indicating position of the slots  in the  frame  to decode  the coded data,  and which  adaptively  applies  appropriate  one  of  error control methods depending on the position of the slots in the  frame.   An estimated value of  the  intra-frame position  information  of  a  current  slot  and  a  fixed variation  amount  per  slot  of  the  intra-frame  position information   are   generated   in   accordance   with   an estimated value of the intra-frame position information of  an  immediately preceding  slot.    Synchronization  is established between a received value and the estimated value  of  the  intra-frame  position  information.    An error control method to be applied to the current slot in the synchronous state of the received value and the estimated  value  is  determined in  response  to  the estimated value of the intra-frame position information of the current slot generated.   The decoder can achieve error control operation of received data correctly even if  an  error  occurs  with  the  received  value  of  the intra-frame position information.

IPC: H04L12/26
Filed: 1995-12-22
Abstract: Faults occurring in a telecommunications system (21) are monitored identifying their time of onset and reporting them to an operator through an interface (16) if they have not cleared within a predetermined interval. Transient faults, which do clear within that interval, are not reported directly, but only if such faults occur more frequently than a predetermined rate. This is determined by establishing a scan interval, and an analysis period equal to a plurality of scan intervals, monitoring the system (21) continuously for the occurrences of faults, and storing their times of occurrence in a store (8).  At the end of each scan interval, the number of occurrences of the fault during the analysis period which ends at the end of the scan interval are counted by a counter (11). If the number of occurrences of the fault in the analysis period is equal to or greater than a threshold value selected by user input (16), an alarm indicator (17) is activated. This allows isolated transient faults to be disregarded, allowing the user to concentrate on recurrent intermittent faults.

Abstract: Composite materials formed from bone bioactive glass or ceramic fibers and structural fibers are disclosed. In preferred embodiments, a braid or mesh of interwoven bone bioactive glass or ceramic fibers and structural fibers is impregnated with a polymeric material to provide a composite of suitable biocompatibility and structural integrity. Most preferably, the mesh or braid is designed so that the bioactive fibers are concentrated at the surface of the implant to create a surface comprised of at least 30 % bioactive material, thereby providing enhanced bone ingrowth. The interweaving between the bone bioactive glass or ceramic fibers and the core of structural fibers overcomes the problems found in prior composite systems where the bioactive material delaminates from the polymer. Preferred bioactive materials include calcium phosphate ceramics and preferred structural fibers include carbon fibers. Further preferred bioactive materials include aluminum oxide at greater than 0.2 %, by mole. Improved prosthetic implants and methods of affixing an implant are thus also disclosed.
