Abstract: It is an object to provide an apparatus for automatically sewing a slide fastener chain onto a cloth piece in which the physical fatigue of a sewing operator can be relieved also when the same operator takes charge of delivery, and the size of the apparatus can be reduced. In a chain sewing apparatus, a slide fastener chain supplied continuously is successively sewn onto a pair of left and right cloth pieces. There is provided chain cutting means for cutting the fastener chain between the cloth pieces moved continuously over a table and suspending from a front end of the table. There is provided a sewn product receiving section having sewn product transfer means for receiving, in a lower part, a sewn product cut away from the succeeding cloth piece having the fastener chain sewn thereonto by the cutting means and transferring the sewn product to a rear end of the table through a lower space portion of the table.

Abstract: A helicopter main rotor blade balance weight retention system and assembly having a base plate (105), at least one support post (107) integral with the base plate and extending out perpendicularly from the base plate, a plurality of balance weights (109), a retaining nut plate (111), and one or more fastening bolts (113) for securing the balance weights to the base plate, and the base plate to the rotor blade. The balance weights (109) include apertures (117, 119) through which the support posts and the fastening bolts pass. The apertures through which the support posts pass are dimensioned such that the a snug fit is formed between the support posts and the balance weight; but the apertures through which the fastening bolts pass are dimensioned such that the threaded portions of the fastening bolts are not subjected to any shear loads from the balance weights due to the centrifugal force generated by the rotating rotor blades. The weight retention assembly is installed into pockets in the blade tip.

Abstract: The inventive method consists in the following: a drillable packer provided with a channel closed by a back valve is arranged in a well; afterwards a tubing string carrying a jet pump and a stinger is run into said well, the stringer being connected to the packer; the back valve is open; a logging instrument and a sealing unit are introduced into the tubing string with the aid of a cable; a depression is produced on the formation by means of the pump, a bottomhole pressure and the parameters of the formation are measured with the aid of said instrument, the parameters of physical fields being recorded. The results of said investigations being interpreted, the technical state of the well is defined. The instrument and the sealing unit being extracted from the tube string, a blocking insert is dropped therein. The tubing string is uplifted, the stringer is disconnected from the packer and the back valve is closed. A cement slurry being pumped into the tubing string, said tubing string is put down, the stringer is connected to the packer and the back valve is open. The cement slurry is pumped into the tail space, squeezed into the productive formation and the tubing string together with the pump and the stringer is extracted. The cement slurry being hardened, the packer is drilled out, the formation is perforated and the tubing string provided with a guiding cone, the packer and the pump is brought in the well.  Said invention increases the reliability of the repair and insulating operations.

Title: Easy dumping cart
Inventor: ZIMMERMAN FELTON
IPC: B60P/
Filed: 2004-01-22
Granted: 2010-04-20
Abstract: The use of a pivotal coupling on a cart (20) of the wheelbarrow type allows for a downwardly applied pressure to the user ends of the handles (22) to tip the bucket (28) to at least begin the dumping action of the cart. Following the initial downward pressure with the handles still elevationally displaced downward an upward lift applied to the user ends of the handles (22) completes the dumping action of the cart (20). Use of multiple pivotal axises (66, 68) on the cart provide for an extremely efficient operation. Various enhancements are explained including locking of the orientation of the cart (22) following the initial dump, wheel blocking to prevent rotation of the ground support wheel (24) relative to the bucket (28) during at least a portion of the final dumping action and stabilization enhancement to prevent lateral tipping of the cart (22) during the final dumping action.

Abstract: A tracking system uses RFID (radio frequency identification) tag technology to facilitate the identification and tracking of items in an environment through a technique known as shadowing. As an object or target moves within a pre-described detection zone with communicating antenna and RFID sensors, the object or target blocks the line of sight between respective antenna and sensors, preventing electromagnetic coupling between the sensor and the antenna and thus casting an electromagnetic shadow along the line of sight.  One approach of this invention uses this shadow technique to perform functions such as theft (shrink) deterrence/ detection; tracking the motion of objects through an environment by monitoring the shadow; and correlation analysis of people shadows to tagged items (e.g., merchandise, articles) to foster marketing and merchandising effectiveness.
