Patent CA-2049389-A1 (CA)
Inventor: RICHARDSON RICHARD J
IPC: E06B3/66
Filed: 1991-08-16
Abstract: A railless refrigerator display door constructed with two or more glass panels and having a peripheral door frame extending around the sides of the door and at the inside of the door without covering the outside glass surface of the door.  Sealant is used to bond the glass panels to periph-eral spacers separating the panels and to C-section struc-tures which extend peripherally around the sides of the door.   The door frame is also bonded to the C-section structures and glass panels by the sealant.  Rubber bumpers attached to the C-section structures reduce cold transfer from the inside glass panel to the outside glass panel.  As such, mechanical fasteners such as nuts, bolts or screws are not needed for the purpose of holding the refrigerator door together.

IPC: H01R43/28
Filed: 1991-12-12
Abstract: ABSTRACT      The object of this invention is processes and devices for the automatic production of bypasses for conductor wire or optical fiber bundle comprising several branches and bypasses.     This  invention enables bypasses through which  each wire section of the bundle must pass to be made:     -    By identifying the points associated with these bypasses for each wire section (7f) by their abscissas on each wire (7f) when they are unwound, and by placing them in bypass clips (3'f);     -    By  forming  these  bypasses  by  grouping  all  of  the intermediary points associated with the same bypass into bypass clips (3'f), taking them from the clips in which they have been arranged.     Branches (7) of bundle (7a, 7b,  ..., 7f) are separate and formed by moving bypass clips (3'a, 3'b, ..., 3'f) apart.     An application is the automatic production of conductor wire bundles.

Abstract: Unused towel rolled up in a shell (4) is guided between a roller (38) and a tracer (40) for detecting the towel end and via a transport roller (6a), forms a loop and runs via a transport roller (6b) to a roller (13) guided in slots (l4a,b) and intended for receiving used towel.        To ascertain whether the loop is being used or not, there is a movement sensor (20) with a bar (22) which is suspended rotatably about a horizontal axis and to which is attached a batten (23) via which the towel (5) is guided.      Clamped in the bar (22) is the upper end of a piezoelectric element which at its lower end is clamped between parts connected to a sensor housing (21).        Since a distinction can be made between use and non-use, it is possible for released unused towel to be retracted again.        Various programs can be selected for operating the towel dispenser, and in particular the loop can be formed from unused and used towel or only from unused towel.
Patent CA-2063769-A1 (CA)
Inventor: BOL IGOR I
IPC: G03F7/00
Filed: 1992-03-23
Abstract: A process in which concave surfaces to form undercut edges can be made and the application of such process to making micromechanical devices. Concave surfaces forming undercut edges are are made in a wall of a stationary structure extending from a planar surface by growing a convex bumper into the wall. The bumper forms a convexo-concave relationship with the wall. The bumper is then removed from the wall in such a manner as to preserve the concave, undercut surface of the wail. The stationary structure and the planar surface is then further processed by coating with a sacrificial layer, and a structural layer. The structural layer is patterned into a movable structure that is held onto the stationary structure by the curved, undercut edge such as the slot in a slider. Final processing includes removing the sacrificial layer to free the movable structure from the stationary structure.

Title: Process for producing colour change devices incorporating latent indicia and the resulting devices
Inventor: SMITH GARY J
IPC: C25D11/04
Filed: 1991-04-03
Abstract: The invention relates to a process for producing colour change devices incorporating latent indicia and colour change devices incorporating latent indicia produced by the process. The process involves anodizing a colour generating metal (11), having limited surface areas thereof covered by a mask (12), in the presence of an adhesion-reducing agent in order to produce a colour-generating laminate incorporating an anodic film (13) having detachable and non-detachable areas (b, a). The improvement of the invention involves forming the mask (12) from a masking material which permits anodization of areas of the surface covered by the mask while preventing the adhesion-reducing agent from exerting a substantial adhesion-reducing effect in the areas of the surface covered by the mask. The anodic film having the detachable and non-detachable areas (b, a) can then be formed by means of a single anodization step carried out in the presence of the adhesion-reducing agent.  It is therefore unnecessary to employ two partial anodization steps as in the past, which simplifies the fabrication procedure and makes the procedure less expensive.

Title: Stirrup assembly for securing a cargo having upper and lower pairs of opposed, ball headed studs extending laterally from each side of a cylindrical, securing stud
Inventor: ROSS JAMES E
IPC: B64G1/64
Filed: 1992-11-04
Abstract: A stirrup assembly for securing a cargo having upper and lower pairs of opposed, ball headed studs, extending laterally from each side of a cylindrical, securing stud, has a side member for attachment of a cargo to, for example, the side wall of a cargo bay of a space shuttle. Two upper U-shaped stirrups are attached to an upper portion of the side member. The upper U-shape of the stirrups have flared entries for receiving the ball heads of the upper studs and have fixed resilient seats, as well as a carriage spring like contact for the ball stud shaft. Two lower U-shaped stirrups are spaced across, and attached to, a lower portion of the side members. The U-shapes of the lower stirrups also have flared entries for receiving the ball heads of the lower studs. Each lower U-shaped stirrup has a spring loaded ball head retaining lever pivotally attaches to that stirrup so as to be depressed by, and swung around, that ball head from the undepressed position. A split bearing is provided attached to the side member for downward urging of the cylindrical stud on the cargo so that the upper and lower ball heads are pushed into their stirrups and the levers are actuated. The cargo is buffered against vibrational loads and the ball heads are held against reverberating in the stirrups. The stirrups and balls accommodate thermal distortions of the cargo. The split bearing, when opened, releases the cylindrical stud and allows the cargo to move and distort from its nominal geometric shape. This relieves contact loads between the balls and stirrups which will allow a low friction force removal of the cargo from the strirrup assembly.

Abstract: 2086667 9200710 PCTABS00010 A catheter device (34) and method for heating tissue, the device having a catheter shaft (10) constructed for insertion into a patient's body, and at least one chamber (8) mounted on the catheter shaft. The catheter shaft has at least one lumen (23) for fluid flow through the shaft. The chambers are defined by walls that are at least in part expandable. Fluid flows, through the lumens (23), between the chambers and a fluid source outside the body. The chambers (8, 9) can be filled with the fluid after they have been placed within the body. A heating device (38) heats liquid within at least one of the chambers, so that heat is transmitted from the liquid to surrounding tissue by thermal conduction through the wall of the chamber. Means are provided for selectively directing heat transmission toward a selected portion of surrounding tissue. The chambers (8, 9) are fillable with fluid separately from each other, so that the chambers can occupy any of a plurality of possible total volumes. By selecting the total volume of the chambers, compression of the tissue can be controlled, and hence the effectiveness of transfer of heat to the tissue can be controlled. According to the method, the catheter device (34) is used to heat tissue from within a duct in a patient's body. The chambers (8, 9) are inserted into the duct and filled with fluid. Liquid is heated within at least one of the chambers, and heat is selectively directed toward a selected portion of surrounding tissue.
