Title: Flexible hose constructions and methods of making the same
Inventor: WINTER JEFFREY J
IPC: B29C48/13
Filed: 1990-08-30
Abstract: Methods are provided for providing novel flexible hose constructions. In one embodiment, the improvement includes the steps of forming an inner corrugated hose of polymeric material to have a plurality of outwardly convex projections with recesses therebetween, then disposing an outer sleeve of reinforcing material in telescoping relation on the inner hose, and then disposing an outer sleeve of polymeric material in telescoping relation on the sleeve of reinforcing material. A tube of polymeric material is disposed between the sleeve of reinforcing material and the inner hose by extruding the tube onto the inner hose before disposing the sleeve of reinforcing material thereon. The inner hose is formed with an outer layer of one thermoplastic material and an inner layer of a different thermoplastic material. The tube is formed from the same thermoplastic polymeric material that forms the outer layer of the inner hose. The outer sleeve is formed of the same thermoplastic polymeric material that forms the tube by the steps of extruding to cause the tube to be bonded to the projections of the inner hose. The bonding of the sleeve of polymeric material is caused to be bonded to the tube of polymeric material through the sleeve of reinforcing material by extruding the sleeve of polymeric material onto the sleeve of reinforcing material. One embodiment of the flexible hose construction of this invention comprising an inner corrugated hose which is made of polymeric material and which has a plurality of outwardly convex projections with recesses therebetween which extend from one end thereof to the other end thereof. An outer sleeve of reinforcing material is disposed in telescoping relation on the inner hose, and a tube of polymeric material is disposed between the sleeve of reinforcing material and the inner hose and extends into a generally-straight-line manner from projection to projection of the inner hose. In this way the flexibility characteristics of the inner hose is not substantially reduced.

Title: Pegblok
Inventor: FREEL DOUGLAS M
IPC: E04C1/00
Filed: 1992-05-06
Abstract: ABSTRACT          Current wall building methods using modular blocks generally employ materials such as concrete, clay, stone,mud and glass, erected with the vertical joints staggered, and relying upon a mortar or other adhesive to bind adjoining surfaces to provide the desired structural lateral stability.          The degree of verticality and flatness of the finished wall is however in direct proportion to the ability of the erector to lay true and even beds, and to continually "adjust" the separate units as the wall grows.          In this invention the modular block is rigid insulation, with various holes running vertically through the block from top to bottom. The block may be manufactured using either extrusion or casting methods, either of which will provide a perfectly true unit, with all sides flat and of exact dimension.          The block, being lighter in weight than conventional block materials, is much larger in size, and is erected in stretcher bond, but with all joints DRY. Lateral stability of the wall is effected by the use of pegs of similar rigid insulation, which are driven through the holes of the blocks vertically,each peg penetrating 50% into each of the blocks above and below.          The wall system of building these blocks relies upon friction for basic strength, together with a staggered horizontal and vertical bond with the pegs providing a resistance against bending.         The pegs offer also the ability to provide an absolutely flat interior and exterior surface of the wall, since each peg locates the blocks above each other with absolute accuracy.          The wall system offers also the advantage of being fast in erection time, and can be accomplished without the use of skilled labour.          The block and peg sizes and shapes will be adjusted to suit the heights of walls required, and the desired friction and bending moments required.

IPC: H01H13/705
Filed: 1992-05-25
Abstract: Abstract of the Disclosure A pushbutton and cover combination for operating an electronic switching device, such as a telephone or keypad.  The cover defines a number of button receiving apertures extending therethrough.  Each button comprises a body having a first part which provides a contact surface and a second part which is slidably received through an individual one of the apertures, so that the contact surface of the button is accessible from a first side of the cover.  Latches on the second part of the button body are cooperable with the cover so that the button is held captive in the cover, with the second part of the body being operable to move slidably within the aperture, for engaging a flexible barrier layer and operating the electronic switching device on an underlying circuit board. The subassembly of the cover with the captive buttons is removable intact from the circuit board and flexible barrier layer of the electronic switching device.  After removal of the subassembly, the latches are accessible and the buttons are removable from the cover.

Abstract: On peut activer l'expression par des gènes n'intervenant normalement pas dans une transcription dans une lignée cellulaire ou dans des mircroorganismes, par insertion d'un élément régulateur d'ADN, lequel est capable de promouvoir l'expression d'un produit génétique normalement exprimé dans cette cellule, ou lequel est sujet à promiscuité, l'élément régulateur étant inséré de manière à être fonctionnellement lié au gène normalement inactif en question. L'insertion s'effectue au moyen d'une recombinaison homologue par création d'une structure d'ADN comprenant un segment présentant un segment d'ADN du gène normalement inactif (ADN de ciblage) et l'élément régulateur d'ADN, afin d'induire une transcription génétique. On utilise également la technique afin de modifier les caractéristiques d'expression de n'importe quel gène endogène d'une lignée cellulaire ou d'un microorganisme donné.
Patent CA-2072743-A1 (CA)
Title: Method and device for detection of particles in flowing media
Inventor: LEONARDSSON LARS
IPC: G01N15/02
Filed: 1990-12-20
Abstract: A laser (1) is applied on the side of a channel which is traversed by a medium. The light beam from the laser (1) passes across the channel. Particles (5) in the medium within the measuring volume are hit by light and deflect this, thus creating forwardly-directed light cones. These light cones are refracted outside the channel by a lens (6) and thereafter hit a detector plate (8). The light which hits the detector plate (8) occurs in the form of light rings which have arisen by light diffraction. On the detector plate (8) at least two detector rings are arranged, consisting of light-sensitive elements adapted to measure the light power in those light rings which fall onto the light-sensitive elements. In an electronic differentiating unit (9) a difference is created between the measured light power values from two of these detector rings. This results in a difference signal which can be related to the size distribution of particles occurring in the flowing medium.

Abstract: A process  for  the  continuous  manufacture  of seamless tube by confining a selected length of metal strip in the form of a tube and with at least two longitudinal abutting edges and completely melting a selected length of such tubular form to form a seamless tube and cooling the formed seamless tube.   The cooling is preferably in a controlled atmosphere of nitrogen and the temperature is reduced to about 700F before further processing takes place.   In a preferred process the material is a single strip  of  metal  formed  into  a  tube  with  only  one longitudinal seam and it is moved continuously through a mould heated by induction heating selectively controlled to cause the tube to preheat to a selected temperature and then be subjected to a temperature bringing the metal to its molten state to form a seamless tube and while the seamless tube is moving it is cooled downstream from the melting zone solidifying the metal and bringing it to a selected temperature before exiting the mould.
