Abstract: ABSTRACT        Multi-mode waveguide filters are temperature compensated using dielectric material contained within at least one cavity of a filter. The variation in operating frequency of the filter that would otherwise result from changes in temperature is substantially balanced by a change in operating frequency with temperature caused by a change in a dielectric constant of the dielectric material so that the operating frequency of the filter remains substantially constant with temperature. The filter can have one or more dual-mode or triple-mode cavities. In a method of constructing and compensating a filter, the amount of dielectric material is selected so that the dielectric material does not resonate at the operating frequency of the cavity, the amount of dielectric material in the cavity being adjustable after each cavity is constructed. The cavity is operated with a fixed amount of dielectric material contained in the cavity for each mode and the change in operating frequency of the filter with temperature is determined. If the change in operating frequency of the filter is not at an acceptable level, the amount of dielectric material contained in the cavity for each mode is varied and the filter is operated through a range of temperatures to determine whether the change in operating frequency is then at an acceptable level. These steps are repeated until the change in operating frequency of the filter is at an acceptable level. When the change in operating frequency of the filter with temperature is at an acceptable level, these filters can be used in satellites without a temperature control system.

Inventor: SCHNITZER JAN E
IPC: A61K35/44
Filed: 1993-08-10
Abstract: A process is disclosed which makes possible the isolation of the luminal endothelial cell membrane from associated tissue. It is particularly applicable to vasculature, but broadly is applicable to all tissue cavities which are accessible from adjacent per-fusable lumens. The method involves the identification of characteristic molecules (primarily proteins and lipids) associated with the luminal surface of any endothelial membrane in situ by utilizing a novel membrane-isolation scheme to separate the endothel-ium from associated tissue. In this method, the endothelial luminal plasmalemma of a given organ is coated with colloidal silica by perfusion, a pellicle is formed, the coated area of tissue is excised and the coated plasmalemma fragments are isolated from cognate homogenate by centrifugation. The isolated plasmalemma attached to the pellicle can then be subjected to biochemical analysis to identify and catalogue molecules characteristic of the endothelial membrane. The method is broadly applicable to any tissue of any organ which is adjacent to a perfusable luminal cavity and which has luminal endothelial membrane exposed to such laminal cavity.

Filed: 1995-04-10
Abstract: An  improvement  is provided  in  a process  for the membrane filtration of a protein solution.  The improvement consists of applying a high shear force at the surface of the membrane.  The membrane filtration utilizes a rotating membrane disc mounted in close proximity to a stationary solid (i.e., unapertured) disc, or a rotating solid (i.e., unapertured)  disc  mounted  in  close proximity  to  a stationary membrane surface.  The rotation is at a speed of between 1,000 and 3,450 RPM, and the close proximity is defined by a space therebetween of 1/8" to 1/4".   This results  in permeation  characteristics  of  the  selected membrane  which  essentially  represents  its  theoretical molecular weight cut-off.

Abstract: A receive condition in burst transmission varies in units of a burst or a plurality of symbol times.      The present invention provides a soft decision signal outputting receiver which can simply produce correct reliability information even if the receive condition varies while employing a simple reliability information production method. A demodulator demodulates a burst signal to obtain a hard decision signal. A time-varying reliability information production circuit receives information of a demodulation process from the demodulator 11 and produces reliability information regarding the hard decision signal. The time-varying reliability information production circuit receives signal quality information which reflects a receive condition for each burst or each plurality of symbol times, and changes, based on the signal quality information, a production method for reliability information or elements such as threshold levels to be used in a production method for each burst or each plurality of symbol times. A soft decision signal production circuit produces a soft decision signal from the hard decision signal and the reliability information.

Title: Lactoferrin receptor protein
Inventor: SCHRYVERS ANTHONY B
IPC: C07K14/22
Filed: 1995-11-06
Abstract: An isolated and purified lactoferrin receptor protein is isolated and purified from bacterial pathogens, including Moraxella and Neisseria, and has a molecular weight of between about 70,000 and about 90,000, as determined by SDS-PAGE. Such lactoferrin receptor protein may be provided in combination with a lactoferrin receptor protein from the bacterial pathogen of a molecular weight of about 100,000 to about 105,000 daltons. The lactoferrin receptor protein may be produced by providing a solubilized membrane preparation from the bacterial pathogen containing lactoferrin receptor proteins, non-lactoferrin receptor proteins and other contaminants, complexing the lactoferrin receptor proteins with lactoferrin and purifying the resulting complexes substantially free from the non-lactoferrin receptor proteins and the other contaminants, and separating the novel lactoferrin receptor protein from the complexes. The lactoferrin receptor protein is useful in diagnostic applications and immunogenic compositions, particularly for in vivo administration to a host to confer protection against disease caused by a bacterial pathogen that produces the lactoferrin receptor protein or produces a protein capable of inducing antibodies in a host specifically reactive with the lactoferrin receptor protein.
