Stapler having a staple track locked in the base by means of a resilient plastic latch.

A stapler of the type having a top cover member and lever member mounted for pivotal movement between an operative position disposed in closing relation with the open top of the magazine chamber of a magazine member and a staple stick loading position displaced approximately 180.degree., a staple stick pusher mounted slidable on a mounting rod within the magazine chamber and a flexible elongated pusher retracting member molded of plastic material having one end portion abutting the pusher apertu...

The present invention relates to a stapling machine which comprises: a stapling magazine for receiving staples which has a staple discharge opening at one end and a cover, pivotally mounted to the magazine at the other end. The cover is pivotally movable between a closed position overlying the magazine and an open position. A staple support is provided within the magazine which supports the staples therein. A follower is slidably mounted on the support for urging the staples toward the discharge...

A guide rail is provided along the length of the inside of a channel shaped frame which staples are loaded in. A staple pushing member, namely, a slider is provided which can move on this guide rail. One end of a tension coil spring is fitted to one side of the guide rail on the inside of the frame, the tension coil spring is brought around the front end of the guide rail and the other end of the tension coil spring is fitted to one side of the slider. The tension coil spring thus exerts a tensi...

An oiling roller for oiling metal sheet. This oiling roller comprises a hollow arbor having a plurality of small holes penetrating the arbor wall on the circumference thereof, the elastic porous pad in a cylindrical form placed over the circumference of said hollow arbor, and means for pressing the circumferential portion of said cylindrical pad in the axial direction of the cylinder.

A concrete block wall panel with mortarless joints in which the blocks are held together by steel strapping and are reinforced by external coatings of glass fiber cement. The walls are handled by pick up rods extending through the panel from top to bottom. A swivel fitting is attached to the upper end of each rod and a pick up base engaging the bottom of the panel is screwed on the lower end of each rod. After the panel is set in a bed of mortar embedding the bases, the pick rods are unscrewed a...

A video camera having a zoom controlling apparatus which readily controls the magnitude of an image to a fixed size. The camera apparatus detects movement of a subject being photographed based on changes in the image signal and detects the magnitude of the subject being photographed by the imaging device. A servo-control maintains the magnitude of a subject being viewed by the camera constant by moving a zoom lens in response to the detected magnitude.

A process to decrease the strength of an electric field produced by a high voltage conductive path on a printed circuit board and printed circuit assembly using same includes the steps of coating the upper side (5) of the conductive path or track (1) with a thick layer of electrically conductive coating material (4); and reflowing so that the upper edges (8, 9) of the track (1) are also covered with a relatively thick layer of coating material. The track (1) is thus embedded in a mass of coating...

In the housing of a setting device for driving fastening elements, a belt-like magazine holding fastening elements in spaced relation is moved through a guide channel transversely of the path of a driving piston. A transport device positioned in the housing moves the magazine through the guide channel in a step-wise manner. A stop lever is pivotally mounted in the housing and is spring-biased at one end into the guide channel. When the magazine is located within the guide channel in the path of ...

A magazine for fastener-driving apparatus includes a guide on which the fasteners are located, a slide movable along the guide under the action of a spring to feed the fasteners into a driving position and a cover which fits over the guide. The cover is displaceable in a direction transverse to the feed direction into a release position to permit the introduction of fasteners into the magazine.
