Abstract: A pair of sweep locks and a corresponding pair of tilt latches are combined and mounted together on an upper rail of a lower sash. The tilt latches and sweep locks are then interactively engaged so that locking the sweep locks latches the tilt latches, and unlocking the sweep locks leaves the tilt latches latched. Unlocked sweep locks allow manual unlatching of tilt latches, and relocking of sweep locks automatically relatches tilt latches.

Abstract: Image-dependent tone and color reproduction processing of digital images is accomplished by creating a spatially blurred and sub-sampled version of the original image, and applying knowledge of the capture device physical characteristics to obtain statistics related to the scene or original captured. The statistics are used for image-dependent linearization of the captured image data based on an OECF model, and in conjunction with information about the output medium, to calculate image-specific preferred tone reproduction curves based on a preferred reproduction model. These curves may be applied to the red, green, and blue channels of RGB-type images to produce preferred tone and color reproduction, or to the luminance channel of luminance-chrominance type images to produce preferred tone reproduction. Alternately, the linearized image data may be reproduced directly.

Abstract: A double mirror objective lens system uses a three optical surface refractor incorporating a convex mirror into a right surface thereof that reflects incident light to a concave mirror, which reflects the light back through the refractor and on toward a focal point of the system. This arrangement yields better resolution images with low spherical aberration, minimal chromatic aberration, and long working distance. A variation of the invention includes another refractor, a right surface of which carries the concave mirror to form a Mangin mirror. This variation on of the invention has even less aberration over increased wavelength range due to better corrected chromatic aberration.

Abstract: A steer-drive for vehicles primarily operated in fluids (e.g., boats and planes) interposes respective left and right orbital gear drives into the vehicle drivetrain between the engine/transmission or/speed-reducer and the vehicle's respective port and starboard propulsion elements. The orbital drive units comprise only an input gear and an output gear interconnected by at least one orbiting cluster gear that is supported in a rotating housing and also meshes only with the input and output gears. The orbital units are designed so that (a) when rotation of the housing is prevented, driving torque is transferred at speed ratios selected to be as close to 1:1 as is practical, and (b) when steering torque causes rotation of the housing, the steering torque is added or subtracted from the driving torque.

Abstract: A bottom portion 11a is formed on an external end portion of a support sleeve portion 11 which is located on an external side, and an engagement recess 43 is formed in an inner peripheral surface of a support sleeve portion 21 which is located on an internal side. That end face of the engagement recess 43 which faces the support sleeve portion 11 side serves as an engagement surface 44. An engagement piece 45 is formed on one end portion of a hinge body 3. The engagement piece 45 is elastically deformed such that its distal end portion is displaced radially inward of the hinge body 3, thereby the engagement piece 45 is allowed to extend beyond a bottom surface of a key groove 41. Thereafter, the engagement body 45 is elastically restored such that its distal end portion is displaced radially outward of the hinge body 3, thereby the engagement piece 45 is engaged with the engagement recess 43.

Abstract: An improved construction for pull-tab game pieces involves the use or two or more substrates, one of which is at least partially transparent. A thermosensitive imaging layer within which game results are direct thermally printed is located between the transparent substrate and an opaque cover layer through which the game results are printed. An opaque substrate precut to form one or more tabs covers the opposite side of the transparent substrate. The game results are revealed by retracting the tabs to view the game results through the transparent substrate.

Abstract: This eyeglass side shield with a snap-in locking member is generally intended for use with eyeglass temples having expanded padding or inserts around and extending forwardly from its ear hook. The side shield is provided with retention ridges abutting a trough formed in the material of the side shield. This trough has a generally “C” shaped cross-section and can be slid onto an eyeglass temple from the front rather than the rear. After placement in position, the snap-in locking member provides an obstruction that prevents the eyeglass shield from being slid forward past the hinge casing for the eyeglass temple. It also serves to further block movement of the eyeglass shield backward past the expanded padding or inserts.

Abstract: A swing exerciser especially suitable for golf exercise uses a handle and cord arranged to move a resistance trolley down a track positioned on the golfer's back swing side. A spring and pulley arrangement resists movement of the trolley down the track, and movement of the handle by the golfer through the curve of a golf swing forces the trolley down the track so that the golf exerciser must overcome the resistance while swinging the handle to strengthen the muscles needed for powerfully hitting a golf ball.

Abstract: A succession of prismatic labels are made on an in-line press by laminating an embossed metallic material web to one of a choice of conventional label stock webs. Within the same in-line press operation, various steps of printing and die cutting are performed on the laminated prismatic label stock web to produce the succession of prismatic labels.

Abstract: Slits 53, 53 are each formed in one pair of first opposite side portions 5a, 5b of a hinge body 5. By this, one pair of second opposite side portions 5c, 5d of the hinge body 5 can resiliently be deformed such that an interval between the second opposite side portions 5c, 5d varies. An outside interval W between the second opposite side portions 5c, 5d, at an opening end, of the hinge main body 5 is designed to be larger than an inside interval between one pair of opposite inner surfaces of a receiving hole 21a. By this, the one pair of second side portions 5c, 5d of the hinge main body 5 are press contacted with opposite inner surfaces of the receiving hole 21a.

Abstract: A sweep lock locking the check rails of an upper and lower sash improves window resistance to negative wind force. The lock accomplishes this by a cam with a pair of locking rims that engage cam receiver projections extending upward and downward to lock along two vertically separated locking lines, which tends to resist sash tilting from vertical as sash are deformed in response to negative wind force. Preferred embodiments of a cam lock and mounting hub include a two-piece hub that snaps together within a rotational opening of the cam lock to form a subassembly ready for mounting.

Abstract: An adjustment assembly enables lateral adjustment of the position of a pivot connection of a first member relative to a second member in a window assembly having a first member, a second member, and a rotatable pivot-mounting element. The pivot-mounting element includes a first pivot-mounting section with a first pivot axis operatively connected to the first member and a second pivot-mounting section operatively connected to the second member. The second pivot-mounting section has a second pivot axis that is generally parallel to and offset from the first pivot axis. An engager section is located intermediate the pivot-mounting sections. Finally, a locking member is provided to cooperate with the engager section and is movable relative to the engager section between a retention position and a release position.

Abstract: A low-pressure processor for processing substrates includes a chuck that engages the substrates' peripheries for purposes of clamping, sealing, and centering the substrates on chuck bodies. For accomplishing all three purposes, a mechanical clamp can be arranged with two sealing regions. One of the sealing regions seals the clamp to a chuck body or an extension of the chuck body, and another of the sealing regions engages a peripheral edge surface of a substrate for sealing the clamp to the substrate. The second sealing region includes an inclined seating surface that engages a front edge of the substrate's peripheral edge surface and divides a clamping force into a first component that presses the substrate against the chuck body and a second component that centers the substrate on the chuck body.

Abstract: The intermittent linear motor of this invention incorporates features which enhance the exhaust scavenging and cooling processes, as well as simplifying overall construction including a compression plenum below the piston where air displaced during a power stroke by the piston is immediately transferred through the combustion chamber allowing said compressed air to immediately begin scavenging exhaust gases as the piston is returned by a resilient member further displacing spent gases from the motor.

Abstract: A sweep lock locking the check rails of an upper and lower sash improves window resistance to negative wind force. The lock accomplishes this by a cam with a locking rim that extends both upward and downward to engage cam receiver projections above and below the locking rim to lock along two vertically separated locking lines, which tends to resist sash tilting from vertical as sash are deformed in response to negative wind force. Preferred embodiments of a cam lock and mounting hub include a two-piece hub that snaps together within a rotational opening of the cam lock to form a subassembly ready for mounting.

Abstract: An electromagnet having one or more coils wrapped around a plate-shaped core produces a uniaxial magnetic field in the vicinity of a substrate surface for orienting a magnetic film deposited onto the substrate surface. Variations in the magnetic mass of the plate-shaped core or in the magnetic permeability of the core mass are made to reduce angular skew and to improve uniformity of the uniaxial magnetic field. The variations generally involve a reduction in magnetic mass or permeability near a center of the core with respect to a periphery of the core. Cavities of various sizes and shapes but having symmetry with a magnetic axis can be formed in the core for this purpose.

Abstract: An iterative application of an optical object recognition method, such as an OCR method, with enhancements and modifications yields improved speed and accuracy. In the exemplary embodiment, after an initial pass of the OCR method on a document image, unrecognized blobs are grouped into unknown regions to which the OCR method is applied via an analysis window. If the contents of the analysis window remain unrecognized at a starting position in a given unknown region, the window can be moved within the unknown region to provide more opportunities to recognize the unknown region's contents. Recognized characters are recorded, and the portions of the unknown regions in which they appeared are removed. This pass of the OCR method recognizes characters in blobs containing multiple characters.

Abstract: An applanation tonometer with a replaceable prism for contacting a cornea has emitter and detector ports arranged opposite each other on opposite sides of a longitudinal axis, with the ports aimed at about 45° to the longitudinal axis. Light from an emitter then passes through the emitter port and crosses the prism axis to be incident and reflected from an emitter-reflecting surface of the prism and become incident on the applanation surface. Light reflected from the applanation surface is incident on and reflected from a detector-reflecting surface opposite and parallel with the emitter-reflecting surface to proceed across the prism axis to the detector port. Such an arrangement produces reliable applanation signals and varies the spacial intensity of light reflected from the applanation surface so that the tonometer can automatically distinguish between concentric and eccentric contact of the applanation surface with a cornea.

Abstract: A disposable bag for a liquid shipping container has a multi ply region arranged to be inflated as the bag empties in such a way as to form a sump at the bag bottom for discharge of pumpable material from the sump.

Abstract: In a flashlight, a shock absorption system cushions the bulb of the flashlight from impulses delivered to the flashlight. The shock absorption system includes a resilient body with outer and inner rings connected by a membrane, the outer ring being supported by the casing of the flashlight and the membrane allowing a predetermined amount of motion of the inner ring relative to the outer ring. The resilient body also supports the rear of the reflector, which carries the bulb, in a frustroconical portion. When impulse is imparted to the flashlight, the front of the outer ring of the resilient body remains substantially stationary, but the inner ring travels, the resilient body absorbing energy from the impulse so that when the inner ring reaches the end of its travel, the reflector and bulb experience a reduced impulse. As long as the impulse remains below a predetermined level, the bulb sustains no damage.
