The invention relates to a continuous and controlled filter device that filters gases and liquids while maintaining a low differential pressure across the filter element. The device automatically advances clean filter medium into the filter seat or window when the differential pressure rises to a predetermined level replacing dirty filter medium with clean filter medium. The advance of the filter medium is effected by a fluid pressure operated expansible device cooperating with an indexing devic...

A flexible coupling is formed by a pair of hubs adapted for mounting on a pair of shafts and interconnected by a flexible serpentine grid. One of the hubs is formed as an indexing assembly including an outer hub member having a first series of internal gear teeth, an inner hub member journaled in the outer hub member and having a second series of external gear teeth of a different count, and an indexing ring having external and internal gear teeth that mate with the respective first and second s...

A rotatable and axially movable detent disc is formed with a periphery having a triangular cross section. The sides of the triangular cross section are formed with circumferentially spaced triangular detent grooves. A detent member is resiliently urged against the periphery of the disc for yieldable detent disc holding engagement in the detent grooves. The grooves provide a plurality of rotational detent positions corresponding to the number of grooves and the apex of the triangular cross sectio...

An indexing device for obtaining and maintaining the desired rotation of an electrode in an electric discharge machining apparatus wherein the coarse annular adjustment of the electrode is accomplished by manually aligning indexing scale lines with a reference line, and then effecting a fine adjustment by means of a reverse reading micrometer.

An indexing device is constructed such that a plurality of cards are filed in order between a base member of the device and a cover member pivotaly secured to the base member. The cards have protruding marginal edges such that, when the cards are filed in order in the device, the exposed portions of the respective marginal edges are in a sequential step-wise arrangement. A plurality of push-buttons are provided in the cover member in correspondence to the marginal edges of the respective cards s...

An indexing mechanism with positive ON and OFF positions for a motor starter switch mounted in an NEMA 3R enclosure. The indexing mechanism includes a shaft having longitudinally extending projections coupled in fixed relationship to a handle, an index element coupled to the shaft, and a yoke having a pin positioned to engage the index element to positively position the shaft to the first or the second position.

An indexing mechanism comprising a body (10) mounted so as to be rotatble about an axis; means (3) for rotating said body about said axis; first cam means (9, 10) for displacing said body along said axis away from an axial rest position during rotation of said body in a first direction; biassing means (11) for restoring the body to its axial rest position on completion of a rotation or a predetermined portion thereof of the body; means (8a) for detecting the axial movement of the body when it is...

An attachment assembly operable on a sewing machine for automatically controlling cyclic movement of the machine sewing needle in a stitching operation. The attachment assembly includes transmission means having an input drive means and an output drive means. The sewing machine main motor drive means is operatively connected to the transmission input drive means and the transmission output drive means is connected to the machine sewing needle drive means. The power transmission drive means inclu...

An angular indexing apparatus including a driver member which is rotated between predetermined limits, and upon return carries therewith a table through the predetermined angle. The limits may be set to predetermine any angle within a given angle.

This invention is an indexing device which consists of several separable rectangular labels held together by a connection on each short edge. Each label consists of an opaque sheet for carrying an inscription, and a transparent sheet for covering the inscribed face of the opaque sheet. When separated from each other, each label is adapted to be held in a pocket, so that the inscription is visible.
