Abstract: Abstract A tactile sensor for sensing an object in contact therewith.  In its preferred form, the sensor compri-ses a plurality of layers disposed in a sandwich arrangement.  A top layer is comprised of a flexible, electrically-insulating material and a plurality of parallel flexible conductive rods.  A bottom layer is comprised of an electrically-insulating material and a plurality of parallel conductive rods that extend at right angles to the conductive rods of the top layer, thus forming a sensory array comprising a plurality of superimposed intersection points arranged in a grid pattern.  An intermediate layer is comprised of a resilient, electrically-insulating material in which is disposed a plurality of parallel conductive posts that extend perpendicular to the plane of the three layers.  These posts are comprised of a resilient con-ducting material.  Each conductive post is disposed at one of the sensor's aforementioned intersection points so as to electrically couple one of the conductive rods of the top layer to one of the conductive rods of the bottom layer.  The conductive rods are formed with a selected cross-section, in order that changes in the amount of pressure exerted on the sensor will produce corresponding logarithmic changes in the contact sur-face area, and hence electrical contact resistance, established between the conductive rods and those con-ductive posts disposed beneath the points of pressure.

Abstract: ABSTRACT:          An arrangement in a tunable high frequency transmitter tube.            The invention relates to an arrangement for transmission of a predetermined fixed frequency by means of a tunable high frequency transmitter tube, as a magne-tron, the tuning of which can be varied periodically by means of a rotatable tuning body driven by a motor. The arrangement comprises a locking hook (22) which is swing-ably mounted on a part connected to the rotatable tuning body and cooperates with a stationary locking disc (11), having a locking notch (14) with a stop surface (15). The locking hook (22) cooperates with spring means (28, 30) urging the active end of the locking hook towards the stationary locking disc (11). The locking hook (22) has furthermore a counterweight (35) situated at the opposite side of its rotation axis (23) as compared with the active end. When the tuning shall be varied periodically the tuning body is rotated in its normal rotation direction, in which case the counterweight (35) will overcome the force from the spring means (28, 30) so that the locking hook (22) is swung to a position in which it is free from the locking disc (11). When a predetermined fixed fre-quency shall be transmitted the motor is reversed, whereby the locking hook (22) under influence of the spring means (28, 30) is swung with its active end towards the station-ary locking disc (11) with the locking notch (14). After reversion of the rotation direction the locking hook (22) engages the locking notch (14) and locks the tuning body in a position determined by the angular position of the locking notch (14).            - Figure 1.

Abstract: ABSTRACT     Disclosed is a curtain hanger comprising a substan-tially C-shaped main frame having a downward opening and a central top portion formed with a vertical. through-hole. A clamp frame of an inverted U-shape has left and right side walls facing each other and it is adapted for clamping the curtain between the side walls and a central portion bridging the side walls.  The clamp frame is provided with an upwardly extending hook capable of being passed through the through-hole of the main frame.  Left and right connecting portions are connected to the lower ends of the main frame and the lower ends of the side walls of the clamp frame via hinge portions having a reduced thickness for supporting the clamp frame in the downward opening of the main frame.  The main frame, clamp and connecting portions are formed in one body by plastic molding.  To mount the curtain, the upper edge of the curtain is inserted into the clamp frame from below, and then the connecting portions are forced upwardly into the main frame.  Thereafter the hook is upwardly inserted through the through-hole.  As a result, the left and right side walls of the clamp frame are urged toward each other by the connect-ing portions with the curtain clamped therebetween.  The hook projecting from the top of the through-hole of the main frame is mounted on a slide runner slidably guided by a curtain rail, whereby the curtain can be hung.
