Abstract: A push notification distribution system centralizes the management and delivery of push notifications to applications executing on electronic devices. Registration requests to register applications for push notifications may be aggregated and sent as an aggregated registration request. The delivery priority of push notifications may be managed according to specified preferences. Upon receiving a push notification intended for an electronic device, a delivery priority of the push notification may be changed if an application identifier associated with the push notification is found on a list of application identifiers with designed delivery priorities.

Abstract: For a vehicle with at least one removable hardtop roof panel and a fixed hardtop rear rooftop, a hinge is provided that attaches to the removable panel(s) and the rear rooftop. In the case of the Jeep® Freedom Top®, both removable panels are attached to the rear fixed portion of the roof using the hinge, enabling the removable panels to be flipped over the rear of the roof.

Abstract: An apparatus for transferring wafers between carriers with different wafer spacings and different wafer capacities includes an elevator with two sets of wafer supporting grooves that extend through a carrier to lift wafers from it to a temporary holding region whereat the first and second groups of wafers can be selectively retained by means of first and second movable retainers and first and second retainer blocks. Each wafer supporting groove includes a steeply inclined surface that contacts one point of an edge of a wafer, urging a peripheral portion of the opposite face against a flat opposite vertical wall of the groove. The steeply inclined surface of another wafer supporting groove contacting the same wafer urges a peripheral portion of the opposite wafer face against a flat vertical wall of the second groove. The first and second retainers each contain V-grooves that are aligned with V-grooves of a corresponding one of the retainer blocks to support alternate wafers in the holding region.

Abstract: A quartz diffusion boat for carrying semiconductor wafers during very high temperature semiconductor manufacturing operations includes first and second quartz rails having first and second sets of wafer supporting grooves, respectively. Each wafer supporting groove of the first set includes a steeply inclined surface that contacts one point of an edge of a first face of a wafer, urging a peripheral portion of the opposite second face of that wafer against an opposite flat vertical wall of that groove. The steeply inclined surface of a corresponding wafer supporting groove of the second set contacting one point of an edge of the second face of the same wafer urges a peripheral portion of the first wafer face against an opposite flat vertical wall of the second groove. The wafers are prevented from tilting away from either flat vertical wall and therefore are held precisely parallel in the wafer supporting grooves.

Abstract: An open framework defining a pair of rows of stalls for livestock, a feeding hopper movable over the rows of stalls and having a pair of food material discharge openings each disposed to deliver food to the stalls of a different row. A pair of feeding conveyors in the hopper each feed material to a different one of the discharge openings and are independently driven and independently controlled by control elements causing the material to be discharged to predetermined ones only of the stalls. The framework includes longitudinal frame sections which provide gates to each of the stalls individually.

Abstract: A device for permitting the simultaneous transfer of a plurality of silicon wafers from one wafer carrier to another, and particularly for permitting a mass transfer between carriers having different wafer spacings. The device comprises two rectangular frames with a portion of the upper frame extending into the lower frame. Both frames are provided with a plurality of wafer slots although in the lower frame there is a greater number of slots and they are more closely spaced than in the upper frame. Each frame is adapted to interface with and be releasably secured to a carrier having a like number of wafer slots. The upper frame is slidable within the lower frame and means are provided to register its slots with different groups of the slots in the lower frame.
