Patent CA-2063676-A1 (CA)
Title: Hinge-lid pack, especially for cigarettes
Inventor: FOCKE HEINZ
IPC: B65D5/66
Filed: 1992-03-20
Abstract: In hinge-lid packs comprising a pack part (12) and a lid (13) hinged to a pack rear panel (15) it is difficult to ensure a precise closed position of the lid (13). This is particularly the case in hinge-lid packs with rounded long-itudinal edges (10,11). To create an additional closing force, outwardly directed deformations, particularly con-vexities (38), are formed in the free portion of collar side panels (28,29) of a collar (26). These convexites abut the inner sides of the lid side panels (17) with an increased friction and thus create an increased closing force. The deformation of the collar side panels (28,29) is a result of longitudinal collar edges (30,31) diverging towards the free edge. As a result, there is a strain of material which effects the deformation of the collar side panels (28,29). A further or alternative closing aid is provided in the form of an upright or inclined cut (39) arranged in the region of the collar side panels (28,29).      As a result of the convexity (38), this cut (39) forms a projecting retaining edge which also abuts the inner side of the pack side panels (28,29) and creates an increased closing force. Moreover, the pack or the blank has a special design, such that rounded contours at the ends of the blanks fit into one another and can be severed from a piece of material without any wasted.

Title: Phase measuring scanning optical microscope
Inventor: WALKER JOHN G
IPC: G02B21/00
Filed: 1990-11-20
Abstract: The invention provides for phase measurement in transmission and reflection scanning optical microscopes. In these microscopes a parallel beam of laser (1) light is focused onto a small portion of an object (4). Light from this small portion is imaged via a pinhole (8) onto a single detector (10). The image is built up by scanning the object and recording the output from the detector for each object position. In this invention the phase image is recovered by subsequent processing of two or more amplitude images.  One image is measured in the usual way; the other or others are recorded with suitable filters (2, 7) placed in the Fourier or output planes of both the illumination (3) and imaging (6) lenses. The two optical filters (2, 7) have amplitude weighting functions g(x, y) which preferably equal c. exp(ax + by), where a, b and c ar real constants.

Title: Radiopaque non-kinking thin-walled introducer sheath
Inventor: FISCHELL ROBERT E
IPC: A61M25/00
Filed: 1992-12-16
Abstract: ABSTRACT   A sheath is described that is non-kinking and with a thinner wall as compared with sheaths that are currently available. To achieve both a thinner wall for the sheath and to avoid kinking, this invention uses a helical metal coil for its interior which is fabricated from flat wire. To provide the thinnest wall sheath which is not readily crushed in normal handling, a wire thickness between 0.00075 and 0.0035 inches can be used with a ratio of wire width to wire thickness that lies between 3 and 80 depending on the wire thickness. A thin plastic covering is coated onto and between the turns of the metal coil or the covering might be attached using heat shrinkable tubing, or by molding or extruding plastic over the thin helical metal coil. A separate plastic cylinder can be placed inside the coils and also plastic can be placed in the space between adjacent turns of the flat wire. At the proximal end of the sheath is an adapter(hemostasis valve) through which the catheters can be placed. This adapter wouldtypically be molded from a plastic so as to both join onto the metal coil as well as mold onto the plastic covering of the metal coil. At its distal end, the sheath wouldadvantageously combine a metal portion for radiopacity and at its extreme end a soft plastic tapered end piece.

Title: Scanning system for touch screen keyboards
Inventor: CASEBOLT MARK W
IPC: G06F3/033
Filed: 1993-05-27
Abstract: SCANNING SYSTEM FOR TOUCH SCREEN KEYBOARDS                 Abstract of the Disclosure A touch screen control system having a plurality of light emitter and detector pairs positioned on opposite sides of a touch screen display. The emitters and detectors are controlled by a microprocessor-based control system that energizes each of the light emitters in a pseudo-random manner. Before each light emitter is energized, the intensity of ambient light is measured by its associated light detector, and the ambient temperature is also measured by a temperature sensor. The intensity at which the light emitter is then energized is controlled as a function of ambient light and temperature. The control system generates a bitmap identifying beams from each light emitter to its associated detector that are obscured during each of several scans of the light emitter/detector pairs. In order to reject false receptions of light from an obscured light emitter beam, the control system processes the bitmap through a predetermined voting procedure. The control system is thus able to minimize the effect of interfering light sources on the performance of the touch screen.
