Patent CA-2049362-C (CA)
Title: Near infrared laser absorbing coating and method for using same in color imaging and proofing
Inventor: SLIFKIN SAM C
IPC: B41M5/24
Filed: 1990-03-30
Granted: 2001-07-03
Abstract: A laser imaging material which can be effectively employed for color printing and proofing comprises a near infrared transparent support film which has a near infrared absorbing layer thereon.  The absorbing layer contains at least one sensitizer which is absorbent at a desired near infrared laser output wavelength and a decomposable binder. Laser radiation at the desired wavelength which acts upon the absorbing sensitizer causes rapid partial decomposition of the binder into gaseous and non-gase-ous products. The rapid expansion of the heated gases causes ablation of inert materials from the surface of said layer onto a re-ceptor sheet thus producing an imaged film (i.e., the laser imaging donor material) and a color print or proof (i.e., the receptor sheet) of reversed sign to the imaged donor material.

Title: Aircraft radar altimeter with multiple target tracking capability
Inventor: HAGAR JAMES R
IPC: G01S13/935
Filed: 1991-08-27
Granted: 2001-02-27
Abstract: An aircraft radar altimeter includes a programmed microcontroller which permits effective simultaneous tracking of at least two targets such that, for example, both ground and obstacles on the ground can be simultaneously tracked, thus avoiding crashes when the aircraft is operating at very low altitudes. The microcontroller is operatively coupled to the radar transmitter and to the receiver so that information relating to a first target can be stored away while a search and track operation is run on a second target. The information concerning a detected second target is likewise stored away and the microcontroller permits alternate tracking of the two targets with the stored information being used as the basis for establishing an initial position for a target when tracking of that target is resumed.

Title: Tamper resistant container lid
Inventor: NELSON JAMES L
IPC: B65D17/40
Filed: 1991-11-27
Granted: 2003-07-15
Abstract: A tamper resistant container lid that provides a tear away strip that cannot be easily removed without evidence of tampering. The tear away strip is comprised of a plurality of tabs joined by integral thin film links that are heat contractible. With the lid mounted on a container and the tear strip folded or pressed down beneath the rim of the container heat applied to the strip will contract or collapse the thin film links securing the lid on the container. The thin film links are a secure method of providing evidence of tampering because the tear strip is nearly impossible to remove without rupturing one or more of these links. A second embodiment of the invention includes a latching mechanism to hold the tear strip in a closed or folded down position beneath the rim of a container while the thin film links are heated to secure the tear strip around the container. A molding apparatus end method is also described for manufacturing parts that require mold undercuts such as the latter tamper resistant lid. A spring biased stripper ring first pivots the portion of a part haying indentations requiring undercuts away from the mold to release the undercut portion before ejecting the part from the mold.

Abstract: METHOD AND APPARATUS FOR PROTECTION OF CABLE SPLICES            ABSTRACT OF THE DISCLOSURE         A method for protectively enclosing electrical cables, wherein a portion of at least one cable is sealably disposed in the interior of a housing,  includes the steps of placing a pressure-relief valve in communication with the housing interior, the pressure-relief valve being selected to pass an encapsulant therethrough on exposure to a predetermined pressure in said housing interior, and introducing an encapsulant under pressure into the housing interior until the encapsulant passes through the pressure-relief valve.  The encapsulant introduction step is practiced by providing a pump having an inlet and an outlet, placing the pump inlet in communication with the housing interior and supplying encapsulant to the pump inlet directly from a bulk encapsulant container.

Abstract: Internal components for a vertical downflow reactor are disclosed, including quench nozzle configurations for symmetrical introduction of a quench fluid into a quench zone. In one embodiment, the quench nozzle includes a closed-ended conduit having longitudinal exit ports or slots proximate its closed end.        In another embodiment, the conduit terminates in a "tee", the lateral leg of the "tee" being sealed off and the quench fluid exiting from the downwardly extending leg. The invention also is directed to an interzone mixing apparatus in vertical communication with the bottom of the quench zone. An inwardly sloping collector tray has an opening concentric with the vertical axis of the reactor vessel for receiving liquid from the quench zone. A mixing device is provided on the upper surface of collector tray in axial alignment with and covering the opening in the collector tray for mixing and contacting liquid and vapor components entering from above the collector tray and conveying the mixed vapor and liquid downwardly through the opening in the collector tray. Flow deflectors are positioned immediately below the collector tray opening for directing liquid flow towards the axial centerline of the reactor. A horizontally disposed collection pan is connected to the collector tray below and axially aligned with the collector tray opening for collecting liquid flowing through the collector tray opening. The collection pan is provided with a radially outwardly flared downwardly extending skirt to disperse the liquid flow from the collector pan toward the reactor walls, onto a perforated tray them onto a distributor tray through which the vapor and liquid may be delivered to the horizontal cross-section of a reactor vessel second catalyst zone in a conventional manner.     A vertical spiral weir may be provided on the surface of the tray panel to add residence time to the liquid on the tray and to utilize the collector tray surface for initiating mixing of the liquid.

Abstract: The pallet container (1) for liquids has a replaceable inner container (2) that is of sheet metal, an outer casing (6) that is formed from a mesh, and a pallet (9) that is in the form of a base pan (10) that accommodates the bottom (16) of the inner container that is formed as a run-off base, in a positive fit. The inner container (2) that is preferably configured so as to be double-walled and of sheet metal, is welded together from a casing (11), a base section (12) and a cover (13).            In order to produce the inner container, a rectangular piece of sheet metal is bent to form a tubular body, and the abutting edges of this are welded.  The tubular body is stretched to form a casing that is of rectangular cross-section.  Then, a peripheral groove that is of V-cross-section is formed into the two end areas of the casing, and is spaced back from its edges, which are then cut to size.  Subsequently, the deep-drawn dished base section with a rounded edge is installed or placed exactly on the outer faces of a groove of the casing and the base section is secured to the casing.  The cover is attached to the casing in the same way.  Base section and cover are welded to the casing. In order to form a smooth transition between casing and base section, on the one hand, and between casing and cover on the other, the transition areas between casing and base section and casing and cover are expanded by applying pressure to the inner container that is installed in a supporting mould.
