Abstract: Structure for neck and shoulder massage in a hydrotherapy hot tub consists of a pillow element against which a person's head rests with a cavity in the pillow element through which a stream of fluid is directed toward the person's neck. The structure includes a surface interposed in the stream of fluid to deflect the stream to impinge on the person's neck downward at an adjusted acute angle thereto. Another form of the structure includes wing portions extending over the shoulders of a person whose head and neck are at the pillow element with conduits and nozzles at spaced intervals directing streams of fluid downward from the undersides of the wing portions onto the shoulders of the person.

Abstract: This is apparatus for closing a box of the type having a hinged cover and flanges projecting from the edges of the cover and body opposite the hinged edges. The flanges have respectively a projection and a well aligned and constructed for the projection to snap into the well when the cover is closed and the flanges are pressed together. A conveyor belt carries the box from a first point along a path past a pair of spaced apart rotating rollers which are mounted edge to edge. A guide rail above the conveyor is positioned and curved to engage the outside of the box cover and swing it over onto the body of the box as the box is carried to the rollers. The rollers are located and spaced apart for the flanges on the cover and body of the box to pass through the bite of the rollers as the box is carried by.

Abstract: The device includes a pair of rollers through oppositely disposed notches through the wall of a tubular section to engage opposite sides of the shaft of a surgical instrument that is through the bore of the tubular section. The tubular section is slideable in a sleeve element and the ends of the rollers are rotatably received in the respective slots of two pairs of slots in the walls of the sleeve element. A pad removably mounted on one end of the sleeve element has a central opening for the instrument shaft to pass through. The pairs of slots converge in the direction of the end of the sleeve element on which the pad is mounted to a distance apart not less than the distance between the bottoms of the notches in the tubular section.

Abstract: This is a device for dispersing a vapor, such as a deodorant or fragrant vapor, into the air when a movable element, such as the actuation arm of a flush toilet, is moved from a usual `at rest` position. A switch responsive to movement of the movable element from its `at rest` position closes a circuit which energizes an electrically actuated means, such as a motor or a solenoid operated lever, which when actuated opens the valve of a container from which a vapor of a deodorant or fragrance is dispersed under pressure. The device is particularly adapted for dispersing a deodorant into the air in a bathroom or lavatory when the toilet therein is flushed.

Abstract: In a system for verifying a person's handwritten signature on a travelers check or the like by comparing the signature with a signature previously written by the person whose name is signed, both signatures are written on signature fields on the face of the check. Each field incorporates a similar arrangement of lines of pressure sensitive material that produces visible marks on the back of the check at points at which the lines of the signatures cross lines of the pressure sensitive material. When the patterns of marks thus produced are compared, dissimilarities between the patterns indicates that the two signatures were not made by the same person.

Abstract: A tool for crimping a connector sleeve onto the ends of cable strands or the like for joining the strands together consists of an anvil arm having a V-shaped notch therein pivotally mounted relative to a base for its notch to be swung into cooperative opposed relation with a V-shaped notch in a die block on the base for crimping a connector sleeve that is placed through the die block notch.The size of the crimp opening, defined by the two notches in cooperative opposed relation, is determined solely by the size of the notch in the die block. The notch in the anvil arm is the same for all crimp opening sizes. The die block has shoulder surfaces that are engaged by end portions of the walls of the anvil arm notch to bring the two notches into precise operative alignment and to stop relative movement of the notches together when they are in the spaced relation that will produce the size crimp desired.

Abstract: A guard barrier system for along the edge of a vehicular roadway or the like consists of substantially solid, resilient, generally cylindrical bumper elements axially mounted on posts for rotation thereon. A plurality of the posts with bumper elements thereon are spaced along the edge of a roadway or the like and are fixed to the ground in generally vertical position. Adjacent posts with bumper elements thereon are connected together to form a continuous barrier system by one or more cables or rails carried on the posts and extending between adjacent posts.

Abstract: A generally hemispheric shaped dome, which has a flat nonskid base, is on the order of 11/2 inches (3.8 cm.) high from base to apex and is made of a hard nonresilient material. It is placed on a substantially rigid support surface which at least coincides in area with the major portion of a person's back from buttocks to shoulder. A person having an area of pain in his or her back presses his or her back against the dome with the apex of the dome at or adjacent to the area of greatest pain, but not against the spinal column.

Abstract: A tone enhancing element incorporated within the mouthpiece of a reed type musical instrument, such as a saxophone or clarinet, has two steps projecting into the air flow-through passage of the mouthpiece at a point opposite the opening over which the reed is mounted. The first step in from the outward end of the mouthpiece is the lower of the two, projecting into the passage less than the second step. The element may be a removable element that can be taken out for cleaning, for example, or it may be an integral portion of the mouthpiece structure.

Abstract: A TV camera is adapted to scan a field that may extend almost 360.degree. around the camera, except for the angular area obscured by the camera body, by means of a double dove prism mounted for rotation in front of the camera lens on an axis that is normal to the optical axis of the lens. The double dove, which has an internal reflective surface, reflective on both sides, at the interface of the two dove portions, is oscillated by drive means to sweep continuously back and forth a selected angular amount less than 180.degree. to cover a scan field of twice that angular amount, so that some portion of the scanned field is always in the field of view of the camera.

Abstract: An improved micro-adjustment apparatus particularly useful with optical apparatus and the like in which a mechanical advantage of the order of 25 to 1 between an adjustment screw and a drive is obtained without lost motion thereby permitting adjustments on the order of a tenth of a micron at the output. The mechanical advantage is obtained without lost motion through bending two flexture blades rigidly attached to one another at one end.

Abstract: A spherical lens has a surface whereon a dichroic coating reflects light of known wavelength, substantially all other light being transmitted therethrough. Within the focal plane of the surface at fixed locations are respective proximal ends of a plurality of fiber light pipes. The distal ends of the fiber pipes are respectively connected to light emitting diodes whereby each diode is associated with one of the locations. In response to light being provided by a first diode, from the location associated therewith a light image of a first proximal end is transmitted to a first small region on the surface. The image of the first proximal end is collimated at the first small region and reflected therefrom. In response to light being provided by a second diode, from the location associated therewith a light image of a second proximal end is transmitted to a second small region on the surface. The image of the second proximal end is collimated at the second small region and reflected therefrom.

Abstract: A three-fold mirror array for a scanning projection system to permit placing the object and image of an annular reflective projection system in an orientation which facilitates scanning and yields an image symmetry identical to that obtained with contact printing in which three folding flats are combined with an annular field projection system. The three folding flats are incorporated in a monolithic assembly having a 90.degree. groove on one side and a fold surface perpendicular to the other folding surfaces on the other side of the assembly thereby permitting a simple pivoting scanning mechanism to be used for scanning a field larger than the narrow annular field available in the projection system.

Abstract: A viewing field splitter particularly useful for simultaneously viewing two sides of an object for alignment purposes in which the two fields are obtained from microscopes mounted to pivot about the center of an arc which is illuminated. The microscope outputs are inputs to periscopes with one mirror from each periscope located on the axis of the pivot such that there is no rotation of the image and path lengths from each optical element to the point of combination of the fields are equal.
