    Abstract: A striking mechanism (20) for the semi-automatic operation of a cartridge firing firearm (10) providing, in combination, a receiver (12); a barrel (11) attached to the receiver; a gas operated slide assembly (13) providing a slide (14) movable within the receiver; a magazine (19), supplying a plurality of cartridges (29), carried by the receiver; and a trigger assembly (26) attached to the receiver and providing a hammer (28); the striking mechanism comprising a bolt (21) reciprocable within the receiver and engageable with the breach (32) of the barrel and the face of a cartridge chambered therein, the bolt carrying a primary firing pin (22); a bolt lock (23) pivotally linked to the bolt for selectively locking the bolt within the receiver; a secondary firing pin assembly (24) pivotally linked to the bolt lock and to the slide, the secondary firing pin assembly providing a secondary firing pin (25), engageable with the hammer and the primary firing pin thereby to strike the primer of a cartridge chambered within the barrel. The present invention also includes a method for converting gas operated cartridge firing firearms (10) from fully automatic operation to semi-automatic operation comprising removing the bolt link, hammer and trigger assembly from the fully automatic firearm; providing a bolt (21) reciprocable within the receiver (12) of the firearm, engageable with the breach (32) of the barrel (11) and the face of a cartridge chambered therein and carrying a primary firing pin; providing a bolt lock (23) pivotally connected to the bolt for selectively locking the bolt within the receiver; providing a trigger assembly (26) having a trigger (16) and a hammer (28) selectively movable once in response to rearward movement of the trigger; and providing a secondary firing pin assembly (24) between the bolt lock and the slide, said assembly being interposed between the bolt and the hammer and providing a secondary firing pin (25) engageable with the hammer and the primary firing pin thereby to strike the primer of a cartridge chambered within the barrel in response to rearward movement of the trigger.

    Abstract: A tubular member useful as an inner liner for the working channel of a flexible endoscope has a distal portion which is specially treated to make it highly flexible and resistant to kinking or collapsing when it bends with the flexible section of the endoscope. The tubular member is also useful as a catheter device or as a component of a catheter device or catheter system. A multiplicity of external ridges on the distal portion of the tubular member reinforce the tubing wall and prevent kinking or buckling of the wall or collapsing of the inner lumen. The external ridges may be formed by convolutions of the tubing wall or by external threads which are formed on the exterior of the tubing wall within the flexible distal portion. An outer helical reinforcing coil may be added between the external ridges to further reinforce the flexible distal portion of the tubular member from kinking or collapsing. The flexible distal portion of the tubular member may be coated with a layer of a flexible polymer to fill in the spaces between the external ridges and to cover the helical reinforcing coil. Manufacturing methods for the tubular member are also disclosed.

    Abstract: A catheter is provided with a heated temperature self regulating tip for insertion in an artery to ablate an atherosclerotic plaque obstruction particularly in coronary and peripheral arteries. The heater is located at the distal end of the catheter and has a winding of fine wire around a ferro-magnetic core with the wire being connected via a transmission line to a high frequency constant alternating current source in the megahertz range. The catheter which may or may not employ a guide wire is inserted into and through the lumen of a vessel and guided usually with the assistance of fluoroscopy to the location of the stenosis. The heater is energized to ablate the plaque, the temperature not exceeding a desired temperature as determined by the Curie temperature of the ferromagnetic material.

    Abstract: A retractable dust control hood for a rotary table saw includes a generally hollow box member which is supported for movement between a working position directly over the saw blade and a retracted position substantially above the saw blade to permit ease of handling workpieces with respect to the saw and a saw support table surface. The hood is supported from a member disposed above the table surface by parallelogram linkage and a counterbalance mechanism including a rod extending between one set of parallelogram link members and a second set of parallelogram link members. A coil spring is disposed around the rod and acts to move the parallelogram link members relative to each other to counterbalance the weight of the hood. The hood includes a transparent window and a lamp for illuminating the interior space of the hood for ease of viewing the workpiece during operation of the saw. The bottom edge of the hood is provided with rub rails which minimize disfigurement of the workpiece when engaged by the hood and moving relative thereto.

    Abstract: A cable reeling apparatus particularly useful for reeling and dereeling cable for seismic signal recording operations includes a lightweight frame on which a propulsion unit and drive shaft for a cable spool are supported. The cable spool is permanently mounted on the shaft and includes a removable side flange so that coils of cable may be mounted on and demounted from the spool. The spool hub and flanges are provided with cooperating grooves for receiving flexible strapping wherein the coil of cable may be bound at circumferentially spaced points before removal from the spool and field operations may be carried out without dedicated spools for each cable coil.

    Abstract: A non-fouling fluked anchor having a yoke-like shank in which the yoke arms are arcuate and pivotally attached to a pointed, center mounted fluke such that the arcuate arms of the shank provide for variable positioning of the fluke point to insure initial penetration of the fluke point in sea floor bottoms having different degrees of hardness. The fluke tip, the yoke frame, and the anchor line tether establish a three point contact with the sea bottom. The arcuate yoke shank arms allow a variable initial penetration angle of the fluke from 15 degrees to approximately 67 degrees. As a relatively harder sea bottom is encountered the anchor, due to the action of the arcuate yoke will pivot to provide a steeper fluke angle to insure penetration. Once the fluke has penetrated the bottom the anchor will then assume the secured position at the conventional holding angle.
