Abstract: The enclosure assembly particularly, but not exclusively, conceived for  spliced  electric  cables,  comprises  a sleeve  of  an  elastomer material, a support whereover the sleeve is fitted in a state of elastic expansion,  said sleeve  being  adapted  to  shrink  about  the  elongate cylindrical objects upon removal of the support. The support comprises a tubular body formed of a strip of a strong flexible material wound into a helix having mutually bonded adjacent turns, the turns being separable by applying a pull force along a substantially longitudinal direction to an end portion of the strip unravelled from the adjacent turns and taken through the interior of the tubular body along a substantially axial direction and out through the opposite end of the tubular body. The tubular body  comprises  at  least  two regions wherein  the helix has different pitches, a fine pitch region and a coarse pitch region; a fine pitch region is provided at the locations of specified portions of the elongate  cylindrical  objects  for  which  the  enclosure  assembly  is intended.

Granted: 2003-11-25
Abstract: An elastomeric tread for a pneumatic tire extends circumferentially about an axis of rotation of the tire and includes an inner tread surface and a pair of shoulders defining lateral edges, the distance between these edges defining the tread width. A pair of ribs extend circumferentially about the axis of rotation and radially outwardly from the inner tread surface. One rib is adjacent to each lateral edge and each rib includes a circumferentially continuous band of at least 10% of the tread width, devoid of lateral sipes or grooves. Each of a plurality of lateral grooves extend axially from rib to rib. One of three circumferentially extending lateral grooves is centrally located, the second and third, axially spaced within 30% of the tread width from a lateral edge. The circumferential and lateral grooves cooperate to define block elements with first and second sides defined by the grooves arranged in two circumferential rows. The circumferential extent between the sides of the block elements is in the range of 75% to 125% of the axial extent of each element. The average depth of the circumferential grooves is at least 18 mm and the average depth of the lateral grooves is between 75% and 90% of the circumferential grooves. The surface area of the block elements is at least 65% of the area defined by a rectangular boundary having two axially and two circumferentially extending sides that intersect extremities of the block element.

Title: Coating process and compositions
Inventor: JONES IAN THOMAS NISBET
IPC: B29C47/86
Filed: 1993-07-06
Granted: 2005-05-03
Abstract: A process for coating a metal substrate for packaging end use comprises applying to a primary substrate a suitable, substantially solvent-free thermosettable composition. The composition is applied as a thermosettable film by extrusion in melt (including plastified) form through an extrusion coating die onto a substrate, and there is relative movement between the die and the substrate so that successive areas on the substrate are coated with the thermosettable composition, so as to form a film. The primary substrate is the metal substrate for packaging end use or an intermediate temporary support from which the applied coating is transferred onto the metal substrate for packaging end use, and the applied coating is thermally cured after extrusion through the extrusion coating die. Compositions suitable for use in this and other coating processes are described.

Granted: 2005-02-15
Abstract: A system for purifying water supplied to a dynamic dental instrument (10) has a  disposable element (20) having an iodinated resin (23). Disease causing microorganisms in water flowing through the element are neutralized with neutralizing agents released directly into the microorganisms when the microorganisms come into contact with the resin (23). Residual iodine is released as water passes through the resin (23) and remains between the element (20) and the dynamic instrument (10) to maintain dental unit water purity. A modified system for purifying water supplied to a dental unit and dynamic dental instrument (100) has two disposable elements (120, 122), each having an iodinated anionic exchange resin (23, 126) containing a continuous fix-rate released iodinated resin I(n). Iodine is released from the resin at a specified and consistent rate as water passes through the resin (23, 126) to maintain dental water purity.

Title: Circular bar code data analysis method
Inventor: BERNDT KLAUS W
IPC: G06K7/00
Filed: 1995-08-02
Granted: 1996-12-24
Abstract: A system evaluates the data derived from scanning a circular bar code element. The elements in the circular bar code extend radially outwardly from a center of the label, and their width varies along the radial direction. For that reason, should a circular bar code reader be offset relative to the center of the label, it is possible that the circular bar code reader would develop analog signals of the width of elements that vary within a single scan. At one location on the label, an offset reader may read one analog signal for a wide element, and at another location may read a wholly different signal for a wide element with an identical width. To address this problem, an element under evaluation is compared to adjacent elements, and a determination is made of whether the particular element is wide or narrow. Any offset will cause minimal variation in adjacent elements. Several methods for using this basic concept are disclosed. The invention also provides an improved method of switching between digital signals indicating dark or light elements. The analog signal is separated into two branches with a first branch being directed into a delay. The second branch identifies a peak value for the particular element, and then develops a signal proportional to that peak value. The delayed signal is then compared to that proportional signal, and when the delayed signal crosses that proportional signal, the digital signal is switched between the dark and light readings.

Abstract: Le procédé et l'appareil de la présente invention limitent la puissance de sortie d'un radiotéléphone fonctionnant, dans le mode de réalisation préféré, dans un système cellulaire. Ils assurent que les bandes latérales transmises et le bruit de phase du synthétiseur restent à l'intérieur de certaines spécifications. Pour ce faire, on utilise un détecteur d'alimentation ainsi qu'un accumulateur de correction, lesquels génèrent ensemble un signal de commande de gain par limitation du réglage du gain à une valeur maximum, même lorsque le site cellulaire communiquant avec le radiotéléphone envoie des commandes de mise en circuit d'alimentation au radiotéléphone. Ce procédé comprend la correction dynamique du niveau de sortie de l'émetteur du fait des variations de gain dans les étages de l'émetteur ou dans des éléments de commande de gain.

Abstract: Apparatus for forming a chain of sausage links is described in which the formed links are less likely to unwind. The apparatus includes a conveyor (10) for moving a tubular food casing (18) filled with a food emulsion around an axis (12), the conveyor having a plurality of crimping (14a-h) and twisting (15a-h) means for forming a continuous adjacent links.

The links so formed have a first set twisted in one direction about the tubular food casing axis and a second set of adjacent links twisted in the opposite direction. The twisted links are then fed to apparatus (90) for arranging the twisted sets of links in vertical hanging loops (91) using a screw thread (104) of variable decreasing pitch with clamps (96) for clamping between the oppositely twisted sets of links so that as the twisted links move along the screw thread (104), oppositely twisted sets of links form hanging loops which have little tendency to unwind.

Title: Stent with variable features to optimize support and method of making such stent
Inventor: RICHTER JACOB
IPC: A61F2/84
Filed: 1997-07-22
Granted: 2004-11-16
Abstract: An intravascular stent especially suited for implanting in curved arterial portions or ostial regions. The stent can include an end region which is fabricated to have a greater radial strength than the remaining axial length of the stent. Such a scent is particularly suited for use in ostial regions, which require greater support near the end of the stent. The stent alternatively can include sections adjacent the end of the stent with greater bending flexibility than the remaining axial length of the stent. Such a stent is particularly suited for use in curved arteries. The stem can also be constructed with an end that has greater radial strength and sections adjacent the end with greater bending flexibility. Such a stent prevents flaring of the stent end during insertion.
