IPC: G21G4/08
Filed: 1996-11-25
Abstract: A novel brachytherapy device is disclosed that is formed from a hollow-tube-shaped seed-substrate, allowing the easy association of the device with suture material. This shape minimizes the chance of migration of implanted seeds due to better attachment to tissue. The distribution of the radioactive material on the exterior surface of the tubular device provides a relatively uniform radiation field around the hollow-tube-shaped brachytherapy seed source.  Brachytherapy devices are disclosed that are inherently radioactive. Also disclosed are devices that can be rendered radioactive by the transmuting effects of neutron irradiation. Brachytherapy devices are disclosed that facilitate medical application and improve safety for patients and medical personnel.

Title: Peanut allergens and methods
Inventor: COCKRELL GAEL
IPC: A61K38/00
Filed: 1996-09-23
Abstract: Peanuts are a common cause of food hypersensitivity reactions. The sera of 10 patients who had atopic dermatitis and a positive double-blind placebo-controlled food challenge to peanut were used to investigate the major allergens of peanut.  Crude Florunner extracts were fractionated by anion-exchange chromatography using a step gradient (limit buffer, 0.05M  BisTris/1.5M NaCl). A protein peak (OD 280) which eluted at 10t NaCl and demonstrated intense IgE-binding was further analyzed by two-dimensional SDS-PAGE/immunoblot analysis. The majority of this fraction is a protein which has a molecular weight of 17 kD  and a pI of 5.2. Sequencing data from the N-terminus revealed the following initial 9 amino acids: (*)-Q-Q-(*)-E-L-Q-D-L.     Based on IgE-binding activity and no known amino acid sequence identity to other allergens, this allergen is designated Ara h II. Ara h II may be used to detect and quantify peanut allergens in foodstuffs. Serum IgE from patients with documented peanut hypersensitivity reactions and a peanut cDNA expression library were used to identify clones that encode peanut allergens. One of the major peanut allergens, Ara h I, was selected from these clones using Ara h I specific oligo-nucleotides and polymerase chain reaction technology. The Ara h I clone identified a 2.3 kb mRNA species on a Northern blot containing peanut poly A+RNA.     DNA sequence analysis of the cloned inserts revealed that the Ara h I allergen has significant homology with the vicilin seed storage protein family found in most higher plants. The isolation of the Ara h I clones allowed the synthesis of this protein in E. coli cells and subsequent recognition of this recombinant protein in immunoblot analysis using serum IgE from patients with peanut hypersensitivity.

Title: A process and apparatus for pressing materials
Inventor: RODRIGUEZ LORENZO
IPC: B30B9/04
Filed: 1997-01-24
Abstract: The invention relates to a process and apparatus (20) for pressing materials (21) in which a material (21) is compressed by a piston that vibrates lengthways at an ultrasonic frequency to reduce the compression resistance of the material and to augment the compression effect; in practice, "static"  compression, whereby an element is moved under the effect of pressure applied to it, is replaced by a succession of high-frequency blows; the process can be used in particular for squeezing materials of vegetable or animal origin in order to extract the juices from them and for manufacturing processes involving materials subject to plastic deformation.

Title: Corona discharge ion source for analytical instruments
Inventor: TAYLOR STEPHEN JOHN
IPC: G01N27/62
Filed: 1997-01-31
Abstract: An ion mobility spectrometer comprises an ion mobility cell (10) into which molecules of a sample to be analysed arc introduced. The ion mobility cell (10) is doped with ions produced by a corona discharge ionisation source (40). In one mode of operation, the corona discharge ionisation source (40) operates to produce a continual dopant stream, and in a second mode of operation, the corona discharge ionisation source (40) produces dopant ions selectively. In the non-continuous mode of operation, the ion mobility cell (10) may be doped with chemical dopant ions instead, switching between the two dopant regimes being accomplished very rapidly. The ion mobility spectrometer is particularly suitable for the detection of explosive compounds and narcotics, the ion mobility spectrum of explosives doped with ions from the corona discharge ionisation source differing from the ion mobility spectrum of such explosive compounds doped with chemical dopants.

Abstract: A support is shown for an image display system that is to be worn on a user's head. The image display system (10) includes an image generating module with at least one optical element (18) into which a user looks to view a generated image and an electronics module (16), both of these modules being removably mountable on the support (12). The support includes a head hugging member (34) having a front portion, a pair of side portions, a top portion and a back portion integrally formed from a material with multidirectional elasticity so that the side, top and back portions conform to and hug the user's head. The support (12) also includes a rigid bill (36) secured to the front portion of the head hugging member (34) so that it extends outwardly from a user's forehead for providing a rigid support onto which the image generating module is mounted. Whereas the image generating module is mounted on the front of the support, the electronics module is removably mounted on a back portion of the support to provide a head mounted display system the weight of which is distributed over the user's entire head. In a second embodiment the support is formed of a cloth cap with a rigid bill for supporting the image generating module.

Abstract: The conveyor system for clinical test apparatus includes a main transport conveyor and a plurality of auxiliary conveyors located alongside the main transport conveyor. The auxiliary conveyors define straight line paths of travel parallel to the straight line paths of travel of the main conveyor. Each of the auxiliary conveyors is operated by drive means separate from the main transport conveyor. Two crossover points are provided between the main transport conveyor and the auxiliary conveyor. One crossover point is an entrance from the main transport conveyor to the auxiliary conveyor and the other crossover point is an exit from the auxiliary conveyor to the main transport conveyor. Each crossover point is controlled by a gate. One of the gates is a divert gate which can be actuated to block the main transport path thereby diverting puck traffic onto the auxiliary conveyor. The other gate is an interface gate which is used primarily to read information on a sample tube before it is introduced into a test apparatus and also functions as a load and unload station for the clinical test apparatus. The conveyor system also has a main unload and load system wherein tubes that have been completely tested are removed from pucks and reloaded with new tubes that are to be tested.

IPC: F16L13/14
Filed: 1997-04-18
Abstract: A process is disclosed for producing a pipe press-fitted connection which consists of a press-fitting with a stop and a smooth-ended pipe section which can be pressed therein. Once the pipe section is cut, the cut end is trimmed and if required the pipe protection layer is removed. The thus prepared pipe end is inserted into the press-fitting up to the stop and then pressed by a pressing tool with individual pressing jaws which positively and formfittingly engage the pipe section inserted therein to form a non-releasable and tight pipe connection. The individual pressing jaws complete each other towards their pressing ends, forming a closed pressing chamber. A characteristic stamping is plastically made during pressing in the contact area between at least one pressing jaw and the outer surface of the pressfitting. The depth of the stamping depends on the quality of the pressing.
