Title: Incinerator improvements
Inventor: BASIC JOHN N SR
IPC: F23G5/14
Filed: 1990-10-11
Abstract: TITLE: INCINERATOR IMPROVEMENTS      INVENTOR: JOHN N. BASIC, SR.                               ABSTRACT     Improvements for an incinerator system including double reburn tunnels, an excitor within a reburn tunnel, a choker for closing off part of a reburn tunnel, a grate near the incinerator's inlet to permit the drying and intial combustion of refuse, an ash scoop which remains out of the water during most of its operation. The use of dual reburn tunnels, along with a damper that permits the closure of at least one of them, permits the efficient and environmentally acceptable utilization of the main incinerator chamber even with minimal refuse contained there. With less refuse, only one reburn unit operates; it will still have sufficient heat and throughput to maintain, with minimal auxiliary fuel, the temperatures needed for complete combustion. An excitor, or solid stationary object placed within the reburn tunnel, permits the retention and reflection of the heat generated by the burning to assure complete combustion of all hydrocarbons within the reburn unit. Additionally, the air utilized in the reburn unit may enter through the excitor for the efficient distribution and concomitant combustion.          A damper closing off a portion of a reburn unit permits its efficient operation even when the main combustion chamber .     contains very little refuse. Additionally, it permits the incinerator to achieve operational temperatures prior to the introduction of refuse by using only a minimal amount of auxiliary fuel. A grate placed at the main combustion chamber's entrance and above the incinerator's floor permits the retention of newly introduced refuse for a brief period of time. During this time, the refuse may dry, loose its volatile hydrocarbons, and then drop through to the main chamber's floor and undergo its usual combustion. For very high Btu waste, the grate permits the initial, very hot burning to occur off of the incinerator floor to prevent slagging. The ash scoop has a retaining and a nonretaining configuration. It moves along a track downward into the pit while poised in its nonretaining configuration. Once in the pit, it moves to its retaining position to grab debris within the  pit. It then moves back out of the pit along the track until it reverts to its nonretaining configuration to dump the ashes dragged out of the pit.

Title: Method and device for thermal ablation of hollow body organs
Inventor: BEHL ROBERT S
IPC: A61F7/02
Filed: 1990-09-12
Abstract: Hollow body organs, such as the gallbladder, may be ablated by introducing a substantially unheated thermally conductive medium to the interior of the organ. The thermally conductive medium is then heated to a temperature sufficient to necrose the enclothelial lining or mucous membrane of the organ. After the lining or membrane has necrosed, the interior of the organ will fibrose over time and the organ will eventually be resorbed by the body. A catheter useful in performing the ablation method comprises an elongate member having a heating element at its distal tip. The catheter will include at least one lumen for delivering the thermally conductive medium to the interior of the hollow body organ, and the heating means is used to raise the temperature of the thermally conductive medium after it has been delivered. Optionally, the catheter may include one or more inflatable balloons which facilitate sealing of the hollow body organ to inhibit leakage of the thermally conductive medium during the treatment process.

IPC: B29C45/50
Filed: 1990-11-01
Abstract: A B S T R A C T    A low-priced crank type injection apparatus capable of driving an injection screw with a desired driving force without the need of emplying a high output type electric motor.  The injection apparatus includes a crank mechanism (20) for converting forward and reverse rotation of a driving shaft (21), coupled through a reduction gearing (50) to an output shaft (41) of a servomotor (40) controlled by a numerical control device (60), into reciprocating motion of the injection screw mounted on a pusher plate (10), and operates, during the injection process, to cause the injection screw to move forwardly with a great driving force, by the servomotor via the reduction gearing and the crank mechanism.  The servomotor is rotated in such a manner that the driving shaft is driven forwardly within a predetermined rotary angular region corresponding an operational region which does not include upper and lower (lead centers of the crank mechanism and the vicinities of the dead centers, to thereby prevent rapidly changes in the injection speed and in the changing rate of injection pressure, which respectively change in dependence on the rotary angle of the driving shaft.

Inventor: MARSCHOLL KLAUS
IPC: E05F15/697
Filed: 1991-08-26
Abstract: ABSTRACT OF THE DISCLOSURE    An electric-motor drive system for a bowden-cable window lifter is provided hereby.  The system includes a braking spring in the form of a helical spring in the manner known from manual bowden  cable window  lifters.   This  is made possible by the inclusion on the worm wheel of an arcuate slot crossed by a tab affixed to the cable reel and extending to the other side of the worm wheel into the clearance of a ring affixed to the worm wheel.          The ring and the tab are enclosed by the helical spring of which the bent-off ends each enter the gap between the tab and ring.       These components (ring, tab, and spring) are combined to one side of the worm wheel, and achieve the locking of the cable mechanism -- by expanding the spring against a surrounding braking, surface -- when the mechanism is actuated in reverse by movement of the window pane.  Owing to this braking mechanism it becomes possible to  select the pitch of the worm and worm-wheel at the most advantageous angle irrespective of the otherwise required self-locking between the worm and worm wheel ordinarily used to stop undesired pane movement.

Patent CA-2056772-A1 (CA)
IPC: B29C45/23
Filed: 1991-12-02
Abstract: The strokes performed in the direction of the injection axis by a valve-actuating cylinder disposed near the rear portion of the plasticizing cylinder are transformed by a motion-deflecting lever into opening and closing movements of the valve needle. The motion-deflecting lever is disposed within the protective skeleton, which surrounds the plasticizing cylinder. Said lever is pivoted to said skeleton by supporting pivot means. The valve needle extends rearwardly to a location which is radially aligned with the feed screw when it is in its foremost position. The valve needle extends in a needle-guiding bore, which is formed in the plasticizing cylinder and has a relatively wide rear portion having an open rear end at a location which is radially aligned with the back flow valve when the feed screw is in its foremost position. Owing to that design the means by which the movement effected by the valve-actuating cylinder in the direction of the injection axis is deflected and transmitted to the valve needle, which is inclined relative to the injection axis, can be manufactured at much lower cost.
