Abstract: A sports ball having a convex surface with a plurality of dimples formed in the surface. The dimples are sized to receive a substantial portion of a finger tip of a user so as to permit the easier grasping of the ball. The dimples are spaced apart and sized so that upon grasping the ball a given fingertip substantially occludes only a single dimple. For a spherical ball the size of a regulation basketball, the dimples create the general appearance of the known golf ball.

Abstract: A convertible 2D/3D autostereoscopic display includes of an electronically controllable display screen for displaying two dimensional images thereon and a permanently mounted first lens sheet for projecting 3D autostereoscopic images in a region of space in front of the display. Another lens sheet is pivotally attached to the display to allow it to be swung into and out of physical optical engagement with the first lens sheet. The lens sheets each have complimentary physical structure and optical properties such that when the lens sheets are engaged, the combined lens sheets have a substantially negligible effect on the two dimensional screen image; while disengagement of the lens sheets resumes the display to the 3D autostereoscopic display mode. Complimentary alignment structure is also provided in corresponding non-lens regions of the lens sheets for aligning the respective lenslets when the sheets are engaged. Conventional latches are also provided to secure the lens sheets when they are engaged.

Abstract: A sleeve for a magnetic roller to transfer a developer from a supply to a developing zone. The sleeve having a surface layer formed by burnishing the sleeve with a diamond, wherein the surface layer has an increased resistance to oxidation. A surface contour is formed on the sleeve to lie entirely within the surface layer, wherein the surface contour has a sufficient size to triboelectrically charge the developer. A method for forming the surface finish includes cutting the sleeve with a diamond and impacting a slurry against the sleeve to form the surface contours.

Abstract: This door joint comprises a fixing element (1) covering a projecting part (2) of a door-frame (3) and two tubular elements (6 and 8) made of a material deformed in an elastic manner, whereby one tubular element (6) adjoins the other tubular element (8) and said fixing element (1), said tubular elements (6 and 8) are to be interposed between door-frame (3) and associated door (7) in its closed position in order to ensure the tightness of the assembly.According to the invention, the two tubular elements (6 and 8) communicate through at least one orifice (9) or through a continuous passage, whereby the compression of one of the tubular elements (6) between the door and the door-frame results in the deformation of said latter element and in an inflation of the second tubular element (8) between said door and said door-frame.

Abstract: A thermal cycling system comprising an evaporator and a radiator and two separate conduits extending between the evaporator and the radiator to form a closed cycle. The evaporator is arranged to receive thermal energy available around the evaporator and the radiator radiates heat of the fluid medium flowing from the evaporator to the radiator. A power-free engine is arranged on the first and second conduits and comprises actuating pistons, at least one pressurizing cylinder, and a crankshaft operatively interconnecting the actuating pistons and the pressurizing piston. The arrangement is such that the actuating pistons are moved by the high pressure of the fluid medium in the evaporator and thereby actuate the pressurizing piston. The high pressure fluid medium is controlled such that it flows through the actuating cylinders to the radiator and radiates heat there at.

Abstract: In a process for manufacturing finite extruded profiles (3) from elastomer material with at least one projecting sealing lip (12) of different contour (32) over the length of the profile, for simple and very accurate manufacture the invention proposes that by means of two needles (10, 11) which act laterally on the sealing lip (12) and whose depth of contact (a) is controlled by a cam disk (5), the specified contour configuration (32) in the corresponding profile area (12) is incised in the form of grooves and the projecting profile section (38) severed after vulcanization (FIG. 1).

Abstract: In order to facilitate manufacture and assembly of a rigid cover for a vehicle roof with a peripheral seal opposite of the roof opening there is provided according to the invention that the gap seal (3) is manufactured from an elastomer and in the shape of a coextruded profile with a profile area (10) comprising the glass panel (2) and the rim (16) of the base frame (15), and has a U-shaped reinforcement (20) on the inside and a profile area on the inside in the shape of a hollow chamber seal (22) made of sponge rubber, which is delivered as one module with the four corners (30-33) flexed into a frame (6) still open on the posterior lateral side; during assembly this module will be laterally attached to the rim of the other module consisting of glass panel (2) and base frame (15), and the open frame ends (7, 8) are glued and screwed together (FIG. 2).

Abstract: Radial gradient index of refraction (GRIN) optical relays for overcorrecting axial chromatic aberration and a method for their manufacture are described. A relay including a radial GRIN rod in combination with a holographic optical element, or simple homogeneous or GRIN lenses, is described for adjusting axial chromatic and monochromatic aberrations, including spherical, coma, astigmatism, and distortion. The invention also describes remote viewing scopes, such as endoscopes and borescopes, which utilize said relays for achromatic, and reduced or corrected monochromatic aberration imaging. The use of segmented said relays provides a slight degree of flexibility in certain remote viewing scopes. A method for producing an exemplary negative dispersion GRIN lens is disclosed.

Abstract: A heating unit and control system for warming tissue exposed during an open surgical procedure to an ambient temperature below body temperature, such that the exposed tissue remains substantially at body temperature. Heated air is blown through a duct to be introduced into the surgical field where the temperature of the tissue and the temperature of the exiting air is monitored and processed by a control system to insure maintenance of the tissue at substantially body temperature.

Abstract: An autostereoscopic display is disclosed having an optical system and one or more light sources which provide high brightness of the observed three-dimensional images and a high brightness-to-input-power ratio by having the light beam passing through the optical system (including a flat monochrome or color display panel) directed to the observer's eyes, instead of being diffused across the field of view.

Abstract: A gamma radiation dosimeter comprises a polyester film substrate, of which a central circular region is coated with a gamma-radiation sensitive layer which is covered by an overlayer. The radiation-sensitive layer is formed from styrene-acrylonitrile copolymer and contains 1-bromoadamantane and a leuco dye. The overlayer is formed from an acrylic resin binder containing a UV-absorber. The central region is surround by an annular region which is divided into six equally-sized sections, each of which is printed in a color which corresponds to the color developed in the central region when it has been exposed to successive increasing amounts of gamma radiation. After exposure of the device, the amount of radiation to which the device has been exposed can be determined by comparing the color generated in the region with the colors of the six sections.
