Abstract: A strap tensioning apparatus for a strapping machine comprises a large pulley which is power rotated during strap feeding by powered rollers pulling strap off of a feed strap coil. Tension is maintained on the end of the strap being pulled from the feed strap coil by inertial movement of the large pulley and other rotating elements after power to the rollers is stopped.

Abstract: A multi-faceted photographer's vest (10) includes a half of a typical camera strap (12) extending from the right shoulder area, and a half of a typical camera strap (14) extending from the left shoulder area. Each camera strap half (12),(14) has a material end (16),(18) that is sewn or stitched to the vest (10) in the right and left shoulder areas, respectively, so that they are permanently and securely attached thereto. Each camera strap half (12),(14) also has a free end (20),(22) that lays approximately mid-torso, on the right and left sides, respectively, of a vest wearer (24). The free end (20),(22) of each camera strap half (12),(14) is attached to a camera (42) in a typical manner. The vest (10) also provides several pockets and compartments (44),(62) for storing photography related accessories and other items.

Abstract: A pressure-sensitive grip measuring device 10 for use in training or assisting athletes in developing a proper hand grip. The device 10 includes a pressure-sensitive grip 14 comprising an electrically conductive shaft 12 having a plurality of grooves 22 formed annularly therein, a like plurality of elastic insulating rings 24 disposed in the plurality annular grooves 22, and an electrically conductive wrapping 26 disposed annularly around the electrically conductive shaft 12 and the elastic insulating rings 24. The electrically conductive wrapping 26 is typically covered by a non-electrically conductive protective material such as a rubber golf club grip. The device 10 also includes a housing 16, attached to one end of the electrically conductive shaft 12, for retaining a battery 18 and a user detectable indicator 20. An electrical circuit is formed in the device 10 such that a normally open switch is formed between the electrically conductive wrapping 26 and the electrically conductive shaft 12.

Abstract: A pressure-sensitive grip measuring device 10 includes a handle 12 comprised of an electrically conductive splined core 22, a non-electrically conductive deformable material 28 disposed annularly around the splined core 22, a electrically conductive material 34 disposed annularly around the deformable material 28, and a protective material 36 disposed annularly around the electrically conductive material 34 and the entire handle in general. The device 10 also includes an electrically conductive shaft 14 connected to the splined core 22, and a case 16 housing a battery 18 and a user detectable indicator 20. An electrical circuit is formed in the device 10 such that a normally open switch is formed between the electrically conductive material 34 and the splined core 22. When excessive pressure is applied by a user to the handle 12 the switch is closed and the indicator 20 becomes active. Thus, the user is alerted when such excessive pressure is applied.

Abstract: A novel spring and dual pulley construction wherein the pulley includes a pair of co-axial grooves, one of the grooves having a constant diameter that accepts a powered cable acting in one direction, while the other groove has a varying radius of curvature that accepts a second cable connected to one end of the tension spring and with the other end of the spring fixedly mounted. This arrangement maintains a constant spring force on a member moving along a slide in a reciprocating fashion and having one side thereof connected to said powered cable for movement in one direction and the other side connected to the second cable for movement in the opposite direction activated by a constant spring force regardless of the extension of the spring.

Abstract: A printer apparatus for a document handling machine is adapted to obtain a signal from a series of information-bearing marks on a first document and transmit that signal to the control device for the printer apparatus to initiate the printing of an image such as a bar code on a second document which is to be furnished in a mailing envelope along with the first document. The printer apparatus automatically removes the second document from a hopper, advances the second document to a printing station, lowers a print head module to the printing station over the second document, prints a specified but variable bar code on the second document, and delivers the imprinted second document to the transport raceway of a document insertion machine.
