Patent CA-1332027-C (CA)
Title: Composite rocket motor with integrated composite fins,  and method of manufacture
Inventor: DAFFIX LOUIS
IPC: F42B10/04
Filed: 1989-04-21
Granted: 1994-09-20
Abstract: ABSTRACT OF THE DISCLOSURE       A tubular preform (10), fins (30), and fin supports (20) are made independently, with the fins and the fin supports being made by laying fibrous cloth impregnated with polymer-izable binder to take up the appropriate shapes, and then polymerizing the binder, whereas the tubular preform is made by winding a thread impregnated with a polymerizable binder.  Each fin support has a base integrated with the periphery of the tubular preform, and has fin attachment portions projecting from its base, with the bases of the fin supports and the periphery of the tubular preform being shaped in such a manner as to ensure circumferential continuity of the structure.  The fin supports are integrated with the tubular preform by gluing together with at least one position of localized overwinding at the gaps in the fin supports between the fine attachment portions, thereby providing a preform which is smooth in structure both inside and outside.  The assembly constituted by the tubular preform, the fin supports, and the overwinding is polymerized in order to obtain a tube for constituting a rocket, and the fins are subsequently assembled to the fin support by gluing the sides of the fins onto the attachment portions of the fin supports.

Title: Method and apparatus for treating waste paint sludge
Inventor: JOHNSON JEFFREY C
IPC: B09C1/06

Granted: 1994-02-08
Abstract: METHOD AND APPARATUS FOR TREATING WASTE PAINT SLUDGE ABSTRACT A method and apparatus are disclosed for the treatment of paint sludge and for reducing volatile organic compound emissions from a paint spraybooth operation, thereby obtaining a recyclable material for use in new coating products. In such an operation, uncured paint resins mixed with volatile organic compounds are sprayed onto an article to be painted and at least a portion of the overspray is mixed with water to form a waste stream containing water, uncured paint resin, volatile organic compounds and inorganic substances. The method comprises the steps of: removing a portion of the water and liquid volatile organic compounds from the waste stream, heating the resultant sludge to volatilize the residual water and liquid volatile organic compounds and to cure the uncured paint resin, collecting the residual solids stream, and removing all of the volatilized organic compounds from the resultant said stream thereby generating a volatized organic compounds-free gas effluent. The amount of said volatized organic compounds removed is at least about 5% of the volatile organic compounds input to the paint spraybooth operation. The apparatus comprises a waste paint stream dewatering device, an enclosed rotary screw heat exchanger maintained in an inert environment, means for adding a scouring aggregate to the sludge before heating and for removing the aggregate after heating, a separator for removing entrained solids from the resulting gas stream, and a means for processing the gas stream to remove all VOC.

Title: Pulsed light source
Inventor: ROTHWELL HAROLD L JR
IPC: H01J61/80
Filed: 1989-06-26
Granted: 1993-04-27
Abstract: Abstract of the Disclosure PULSED LIGHT SOURCE     A pulsed light source includes a sealed, ultraviolet-transmissive lamp tube defining a discharge region containing a rare gas or a mixture of rare gases, anode and cathode electrodes sealed into the lamp tube at opposite ends, leads for connecting the electrodes to a pulsed source of electrical energy and a phosphor material, located on a surface external to the discharge region.  The lamp tube contains mercury in sufficient quantity to cover the cathode electrode when the lamp tube is oriented with the cathode electrode at the bottom. The cathode electrode is protected by the mercury from sputtering that results from ion bombardment. The mercury emits pulsed ultraviolet radiation which stimulates emission of visible light by the phosphor material.  Lamp tube pressure is below 200 torr. The light source is operable over a range of pulse widths and duty cycles.  The color of light emission is determined by the phosphor.  The phosphor can be located on the outer surface of the lamp tube or on a separate glass sleeve.

Abstract: Millimeter-wave imaging elements and systems are disclosed. The system components may be used for navigation in fog, for example, or for other purposes, including a contraband detection system especially suited for detecting concealed non-magnetic and non-metallic contraband such as ceramic or plastic weapons or illegal drugs. In this embodiment of the invention, plural sources 110 of quasi-coherent millimeter wave radiation are disposed so as to uniformly illuminate a field of view. The radiation emitted by the sources may be linearly polarized in a single plane such that the polarization of the radiation with respect to the plane in which linearly polarized radiation is preferentially received by the detectors can be controlled. For detection of dielectric objects, such as ceramic weapons or narcotics, these planes of polarization should be orthogonal to one another. The detector is a staring array 3 6 which does not require scanning to generate an image of the entire field of view: the signal provided by each element 66 of the detector array corresponds to the illumination reflected from objects in a single portion of the field of view. Real-time imaging of concealed non-magnetic and non-metallic objects is thus made possible.

Abstract: A machine for feeding a collapsed beverage can carrier sleeve to a flight bar conveyor and introducing the sleeve in fully open condition to the pocket of the conveyor. After leaving the feed rolls the collapsed carrier sleeve is moved through a fixed guide by lugs on a movable chain. The end flaps on the upwardly facing side panel are held in place on the guide while the end flaps on the downwardly facing side panel are moved downwardly by a fixed cam surface. The substantially opened sleeve is then either given a final kick by rotating arms or is propelled by the feed lugs to accelerate it into the pocket while at the same time fully straightening and opening the sleeve. The carton dimension corresponding to the length of the pocket is the same as the length of the pocket, resulting in more pockets per conveyor length and permitting operation at slower conveyor speeds.

Abstract: Individually controllable gripper elements are successively spacedly arranged at a ball-and-socket joint-link chain revolvingly driven and guided in a guide channel. At the leading end region of an overhang member of each gripper element there is seated a clamping jaw and at the trailing end region there is arranged a bushing. A shaft is rotatably and displaceably mounted within the bushing. A clamping finger, coactable with the clamping jaw, is rigidly connected with the upper shaft end. At the lower shaft end there is seated a slide shoe and the lower end region of the shaft is encircled by a pivotable element rotatably connected with the shaft. A compression spring rigidly bears for rotation at the pivotable element and the overhang member. When the slide shoe travels onto a stationary cam the clamping finger is raised against the force of the compression spring. An actuation element, which acts upon a further slide shoe, rotates the clamping finger through an angle of about 90 DEG . In this position the slide shoe at the lower end of the shaft travels off the stationary cam, resulting in the clamping finger bearing upon the clamping jaw. Since the compression spring is pre-biased in the direction of the open position of the clamping finger the latter can pivot back into the open position by slightly raising the slide shoe at the lower end of the shaft.
