Abstract: A paper rotation table 15 for use in transporting sheets of paper between paper handling devices while performing a rotation upon each sheet through a predetermined arc so as to present to a receiving paper handling device a leading edge different than the leading edge which emerged from a delivering paper handling device. The paper rotation table 15 has sheet support surface 10, a paper drive 20, a pivot 30, and a registration edge 40. The paper drive 20 further has a drive belt 21, a plurality of primary drive balls 25, and a plurality of secondary drive balls 26, an entry drive ball 23, and a spin drive ball 37. Paper drive 20 may be at an angle "a" to registration edge 40.

Abstract: An edge aligner/holder 10 having an edge aligner 30 with a resilient front end 32 and a tail piece 34 cooperatively interengaged with a reciprocating mechanism 36, and having a holder 20 with at least one rest 23 and one backstop 24, the holder 20 mounted above said front end 32 on said edge aligner 30. The resilient front end 32 of the edge aligner 30 holds a job stack 2 containing sheets which already have been piled in alignment when the edge aligner 30 is in its forward position, while at the same time holding the trailing edge of a next sheet 3, the leading edge of which sheet has already been deposited upon the job stack 2, so that the offset movement of this next sheet 3 may be accomplished without disturbing the alignment and piling of the job stack 2 immediately below it.

Abstract: The invention relates to the field of non-contact surface contour measurement by triangulation of reflected radiation from the surface. More particularly, the invention relates to a system for gathering x, y, z data points with respect to the surface contour of an object by means of time based triangulation methods.

Abstract: A pressure transducer 10 is disclosed wherein a bellows 11 is expanded by an external pressure applied at pressure port 16. The force created by external pressure applied to bellows 11 is mechanically transferred to one end of a vibrating elastic member 14 by axial displacement of saddle 13. A change in external pressure is thereby read as a change in resonant frequency of elastic member 14.

Abstract: The invention comprises a martial arts training apparatus which resembles in movement and function a human leg, particularly in response to a well executed low kick. Leg 10 is mounted to a base 9 upon a bracket 12 above a floor 11 upon which the martial arts trainee stands. The leg comprises an upper leg 20, a lower leg 21 and an extendable foot 47. Upper leg 20 and lower leg 21 are connected by cable 31 and spring 32. A properly executed low kick to leg 10 will cause the leg to "break", pivoting lower leg 21 and upper leg 20 about lower ball 22, and upper leg 20 about upper ball 19 in base 9.

Abstract: A vibrating strip transducer, wherein a vibrating strip 54 mounted between a fixed mount 52 and a moveable mount 51 and under load 53 directly responds to a change in force applied to the strip with a change in the magnitude of stress in the strip. The change in stress produces a corresponding change in the resonant frequency of vibrating strip 54 which is detected by coil assembly 55 to output a frequency based signal directly related to the force applied. Fluid level and buoyancy sensing embodiments are also disclosed.

Abstract: A method of translaryngial retrograde tracheal intubation is disclosed which employs a guide wire 30 having flexible configurations on both ends. A superior end 34 having a magnet 33 therein for cooperation with a magnetic retrievel device is also disclosed. A balloon introducer 10 is disclosed for insertion into a standard endotracheal tube 20 such that after threading the superior end 34 of the orally retrieved guide wire through the tip of the introducer and out the distal end of the endotracheal tube, the endotracheal tube and introducer may be threaded through the oral pharynx 60, through the glottic opening 66, and the vocal chords 67 with minimal trauma to surrounding tissue.

Abstract: A tilting rotational recreational device which has a platform on which the user stands, which platform is freely rotatable upon a bearing. The angle of the platform with respect to the horizontal may be adjusted so that a user standing or sitting on the platform may induce rotational movement of the platform easily by shifting his or her center of mass. One or more additional bearings placed internally in the device optionally provide random and unpredictable rotational movements of the platform, depending on the nature of the user's shift of mass. The device may be locked into a particular angle adjustment, and all internal parts may be held securely together to facilitate safe and reliable use.

Abstract: A rodenticide composition of pelletized rodent toxic plant materials such as a Euphorbia lathyrus and methods of rodent control employing pelletized Euphorbia lathyrus.

Abstract: A jacket comprising a pair of front panels, a back panel, a collar and sleeves. The outer surface of the jacket having vent panels attached to front and rear panels which create accessible, upwardly extending vent panel pockets. Inside each vent panel pocket is a detachable flexible informational display panel which can be stored inside each pocket and hidden from view. When the situation arises, the flexible informational display panel can be repositioned and extended downwardly below the vent panel pocket and used to display information.

Abstract: The present invention relates to a condiment measuring system which is compact, easy to store, and easy to manufacture. The device attaches to standard condiment containers and permits precise and easy measurement of predetermined quantities of condiment with no danger of over dispensing or spilling. In addition, measured quantities of condiment may be measured and stored for later dispensing while still being protected from environmental degradation. The device comprises a housing 10, a metering drum 20, drum retaining disk 30, selector disk 40, and plug 52. The central shaft 11 passes through housing 10 and drum 20 to dispense condiments without measuring, when plug 52 is removed. The device can be built to close tolerances for durability, effective sealing, and ease and smoothness of operation.
