摘要： A device for simultaneously tapping threads and performing the usual operations of a punch press is described in which the tapping device is attached to the upper and lower plates of a punch press. As the punch plates are brought toward and away from each other, gear trains and helically grooved lead screws change the up and down motion into rotating motion. The gear trains also change the speed of the rotating motion which is used to drive a thread tapping tool through the metal being formed in the punch press. If there is too much force opposing the tapping operation, an electrical contact in the device is opened and the punch press stopped before the tap or tapping device can be damaged.

摘要： An electro-optical imaging array having pixels arranged in rows and columns electronically compensates for image motion in the plane of the array regardless of whether the motion vector is in the row direction, the column direction, or in a diagonal direction, i.e., in some vector combination of row and column directions. In an aerial reconnaissance application, the image motion may be due to rotation of the aircraft about roll, pitch and/or yaw angles in addition to forward velocity of the aircraft. The image motion compensation is achieved with no moving parts and does not require a stabilized platform. A camera control computer determines the magnitude and direction of the image motion from inertial navigation system inputs, including velocity, flight, and aircraft rotation information, and calculates pixel information transfer rates in the row and column directions. The pixel information transfer rates are supplied to a counter and clock driver circuit for the array. The pixel information in the array is transferred in the row and column direction in a step-wise fashion in the row and column directions at a rate and direction substantially matching the image motion. The array itself is provided with a gate and control line design to enable charge representing pixel information to be transferred in both the row and column directions.

摘要： Tapping apparatus for tapping holes in workpieces is provided with a tap assembly that includes a tap fitted to a lower tip end of a vertical lead screw, there being means including a bushing for rotating the lead screw thereby to vertically advance and retract the tap relative to the a workpiece hole. Power operating means are provided to rapidly advance and retract the lead screw independently of rotating advance/retraction of the lead screw so as to more quickly locate the tap proximal the workpiece hole allowing that tapping commences with lessened need for lead screw rotation as a means of effecting lineal advance of the lead screw. This lessens the tapping cycle time and results in increased production rate with the apparatus as well as lengthening tap life. The power operating means also functions to rapidly retract the lead screw and tap upwardly from the workpiece on completion of the tapping which also increases production particularly where the workpiece includes heightened structure adjacent the hole location so that more rapid tool clearance is achieved permitting quicker workpiece indexing to present a next to be tapped hole at a tapping station.

摘要： A silicone pressure sensitive adhesive composition which is compatible with drugs, excipients, co-solvents and skin penetration enhancers is disclosed which includes a cohesive strengthening agent in combination with a silicone fluid and a silicate resin. The addition of the cohesive strengthening agent helps to maintain the adhesive on the substrate, while reducing cold flow. The adhesive is useful as an improved component in transdermal drug delivery devices and related medical devices.
