Abstract: A low-cost combination tilt-lock-latch mechanism for a sliding window that combines ease of installation and adjustment with simplicity of use. The mechanism includes at least one tilt-latch mechanism adapted for mounting in the window sash. The tilt-latch mechanism includes a housing and a plunger having a latch bolt portion retractable within the housing. A plunger latch member automatically latches the plunger in a retracted position to enable tilting of the sash. Further, the mechanism may include an actuator mechanism and a flexible linking member. The tilt-latch may include a locking member adjustable from outside the housing of the tilt latch, to lock the flexible linking member to the plunger, thereby operably coupling the actuator mechanism with the tilt-latch.

Abstract: The present invention relates to a process for coating N-[N-(3,3-dimethylbutyl)-L-&agr;-aspartyl]-L-phenylalanine 1-methyl ester onto a carrier. The invention also relates to N-[N-(3,3-dimethylbutyl)-L-&agr;-aspartyl]-L-phenylalanine 1-methyl ester coated carrier compositions.

Abstract: A photo-EMF detector for the collection of photons includes a substrate formed of a photorefractive semiconductor and a plurality of interlaced electrode pairs disposed over the substrate. Each electrode pair includes two parallel electrodes defining an active area therebetween for the collection of photons. One electrode of each pair is disposed between an adjacent pair of electrodes and proximate one electrode of the adjacent pair, light from striking a substrate surface between proximate electrodes and outputs from each of the plurality of interlaced electrode pairs are collected.

Abstract: A latch assembly and process for manufacturing such an assembly and process for painting an assembly with a pivoting member are disclosed. The latching assembly comprises a body, a latch moveable between open and closed positions, and a thumb turn mounted for pivotal movement in the body. The thumb turn includes a cylindrical boss mounted for rotation in the body about a central axis of rotation, and a lever arm extending radially outwardly from the central axis of rotation of the cylindrical boss to a free end exposed outside of the body. A plurality of resilient arms having free hook ends engage the cylindrical boss to hold the cylindrical boss in the body while allowing for rotational movement of the cylindrical boss with pivotal movement of the lever arm. The free hook ends are held in a separate position which prevents rotational movement during the painting step of the manufacturing process.

Abstract: A cover and folding handle assembly for rotating the drive input member of a window operator to open and close a window, including a handle base drivingly engaging the drive input member and an elongate handle having a first end pivotally connected to the handle base so that the handle is movable between an extended position in which the handle is operable to rotate the drive input member and a folded storage position in which the handle overlies the handle base. An opening in the second end of the handle is aligned with an opening in a knob, and an axial pin has a first end received in one of the aligned openings and a second end received in the other of the aligned openings. A rotatably fixed end of the pin is frictionally secured in one of the openings, and the other pin end is received in a sleeve frictionally secured in the other opening and securing a pin head in that opening. The cover has an opening through which the drive input member on the window operator extends.

Abstract: An operator for an awning type window having a sash pivotable about its top side relative to a window frame, with the operator controlling opening and closing movement of the sash relative to the frame. The operator includes a drive gear secured to a base on the frame, a sun gear pivotable about the axis on the base and drivably engaging the drive gear, a primary arm with a planetary gear rotationally attached thereon and drivably engaging the sun gear, a secondary arm pivotally mounted about a second axis on the base, and a pair of drive links pivotally interconnected between the planetary gear and the secondary arm.

Abstract: A window lock having plural ramped keepers for a window sash and plural rollers movably associated with a slider mountable on a window frame to provide multi-point locking. The ramped keepers are constructed and related to enable delayed lock-up of one roller and ramped keeper relative to the other in order to assure locking of racked or warped windows. A roller and associated ramped keeper are bevelled to counteract any flexibility that might be encountered in a flexible window, such as a window made of vinyl. The actuating mechanism provides for toggle positioning of the rotatable actuating handle and associated drive link to prevent movement of the lock mechanism by outside forces other than the handle. One or more tie bars, each having a roller, can be associated with the slider to provide for variation in the number of locking points and with further variations being achieved by the length of the tie bars as well as the number of rollers mounted thereon.

Abstract: A window operator and assembly method therefor wherein a stacked pull arm and gear are rotatably mounted on a bushing carried by a mounting base and the gear and pull arm are assembled to the mounting base with a controlled clearance independent of the tolerance of these components by use of a hardened metal bushing. The hardened metal bushing is forced into the deformable metal of the mounting base whatever distance is necessary to locate an exposed end of the bushing a fixed distance beyond the uppermost of said gear and pull arm and provide a surface against which a washer may be mounted and which overlies the pull arm and gear to hold the components in assembled relation with the controlled clearance.
