Abstract: IMPROVED DIMPLER ATTACHMENT AND IMPROVED FASTENER DRIVING TOOL               ABSTRACT OF THE DISCLOSURE       An improved dimpler attachment for use on gypsum wall board and the like for fastening on a fastener driving tool.  The tool housing has a driving piston, pneumatic or other power means to reciprocate the piston and an elongated driver connected to the piston for reciprocation and extending out of the housing.  A slide connects a dimpler head to the outside of the housing and bears a fastener magazine.  The dimpler head has a central channel slidingly engaging the driver and a pocket adapted to functionally seat a stop plug connected to the driver.  The head is connected to the housing by return springs.  The front end of the head is curved so that it effects a dimpling action when urged forward on the slide by the forward movement of the plug while seated in the pocket during forward movement of the driver. The driver front end preferably is chamfered to facilitate stripping of fasteners from the magazine and preferably is curved to match the head so as to effect flush seating of a fastener in the hole of a dimple made in a substrate during operation of the tool.  The dimpler attachment comprises the described head, slide, return springs and driver which are readily attachable to conventional fastener driving tools.

Abstract: ABSTRACT There is provided a continuous casting apparatus and process, in which molten metal in a tundish passes into a nozzle well and toward a nozzle at the bottom of the well.  During the passage of the molten metal from the tundish to the nozzle, it passes through a plate having a plurality of holes and located above the nozzle, thereby to promote laminar flow below the plate.  From the well, the molten metal is passed through the nozzle to form a stream entering a continuous casting mold.  The presence of the plate promotes a relatively tight, non-flaring downstream flow from the nozzle, and prevents the formation of a vortex in the tundish which would entrain slag into the stream.

Abstract: ELECTRON EMISSION SYSTEM            Abstract of the Disclosure An electron emission system includes a high-brightness field-emitter cathode.  Advantageously, the tip of the cathode is shaped to minimize structural variations caused by surface tension forces.  In addition, an electrode assembly associated with the cathode is designed to establish electric field forces that are opposite and at least approximately equal to the surface tension forces acting on the tip.  The electric field forces can be adjusted to establish a highly stable operating condition without altering the value of electron beam energy for which the overall system was designed.  Moreover, the current density of the beam at a writing surface can be selectively varied without changing prescribed operating parameters of the cathode.  The resulting system is characterized by excellent emission stability, low noise and a useful operating life of at least several thousand hours.
