Abstract: A dispenser for granular food products comprises a hopper for holding a quantity of the product, a pair of back-to-back rotary buckets to alternately receive measured quantities of the product from the hopper, and a semi-automatic electric-powered drive for operating the buckets to discharge their contents seriatim into waiting containers or packages. The preferred embodiment utilizes a cam-switch controlled electric motor which is responsive to push-button triggering.

Abstract: A ladder inclination indicator has a transparent thin-walled body shell defining a rearwardly open recess containing a pivot pin supporting a gravity actuated pointer. A keeper plate forms a partial closure for the recess and carries a label which cooperates with the pointer to indicate a position of ladder inclination. Layers of pressure sensitive adhesive adhered to mounting flanges on the body shell secure the device to the side rail of a ladder.

Abstract: A cartridge consisting of a hollow casing of molded plastic substance and an ink-retention sponge disposed in the casing, together with a stylus carried by the casing, for producing ink lines on a chart, from the ink content of the casing and contained retention sponge. A wall of the casing is transparent to enable the retention sponge therein and the ink carried thereby to be viewed by a user from the exterior of the casing. The intensity of the observed ink color is an indication as to the amount of ink remaining in the casing and sponge.

Abstract: A universal slip-on pen cartridge device for attachment to the movable pen arm of chart recorders, has a molded plastic body with ink reservoir and stylus. The flat surface of the pen body has upstanding spaced-apart posts which secure in place by means of sonic welding a bridge member that has a shallow groove in its face which adjoins the pen body. A tunnel is thus formed with the pen body, into which the pen arm can be inserted, said arm having an aperture which accommodates a nib on the pen body to retain the parts in assembled relation.

Abstract: A universal, snap-on pen cartridge for attachment to the movable pen arm of a chart recorder, comprising a pen body having an ink reservoir and stylus connected therewith and adapted for engagement with a chart carried by the recorder, together with a resilient spring clip engageable with the body and adapted to clamp against an end portion of the recorder pen arm. The said end portion is substantially flat, and is held against a corresponding flat surface of the pen body. A raised portion on the body engages the end of the pen arm and constitutes a positioning device which supplements the clip action. The arrangement is such that assembly of the pen body to the arm can be quickly and easily effected, while at the same time there is provided a connection which is firm and free of undesirable looseness or slippage.
