Abstract:
A fuel injection system (18) is calibrated as an assembled system. The fuel injection system (18) includes a unit pump (10) a cam follower (24), a joined fuel injection line (14) and injection nozzle (16). The fuel injection system (18) is mounted to a test stand an is subsequently calibrated to a specified fuel delivery and timing. The relative positions of the unit pump (10) and fuel injection nozzle (16) are fixed during calibration. The assembled fuel injection system is packaged and delivered so that the calibrated system can be installed in the relative positions fixed during calibration.
Abstract:
A reusable self-aligning precision latch, including a latch body for mounting a latch assembly, and an interface cone is described herein. A lead screw, coupled to the latch body on one end, pivots at an interface on the latch body allowing for self-alignment. A drive cam having a plurality of surfaces and positioned on the lead screw engages a plurality of linkage assemblies such that at least two links are driven. A flexure ball assembly clamped by the plurality of linkage assemblies to the latch body with a pivoting clamp plate such that all clamping forces between the pivoting clamp plate and the latch body are equalized. A motor for closing and opening the self-aligning precision latch by turning the lead screw to apply and release, respectively, the clamping forces between the pivoting clamp plate and the latch body.
Abstract:
A firmware controlled device saves status and configuration information in a separate portion of memory that is not affected by a firmware update. In addition, information that may change during a firmware update, and may need to remain constant, is saved in the separate portion of memory that is not affected by a firmware update. In a first example embodiment, a reset process for the firmware controlled device is divided into two portions. In a first portion of the device reset process, the contents of the separate portion of memory are updated, either from firmware or by interaction with other devices. In a second portion of the device reset process, all other reset functions are performed. The first portion of the reset process is performed only during a power-on reset, or in response to an overall system reset. In particular, the first portion of the device reset process is not performed after a firmware update. In the second example embodiment, data that needs to remain constant are copied to the separate portion of memory as part of a firmware update process. Then, as part of a reset process, the device checks to see if a firmware update has occurred. If a firmware update has occurred, the data in the separate portion of memory are copied to the appropriate destinations, and the data in the separate portion of memory are cleared. As a result, for either example embodiment, the contents of the separate portion of memory are not disturbed during or after a firmware update, and a system reboot is not necessary after a device firmware update.
Abstract:
A method for the preparation of a lactam compound of formula ##STR1## wherein R'.sub.1 and R".sub.1 independently are acyl or aroyl, or taken together form an optionally substituted methylene, and G.sub.1 is hydrogen or an amino protecting group, comprising oxidizing a bis O-protected 1R-2-azadihydroxybicyclo-�2.2.1!heptane compound of formula ##STR2## with about 0.1 mol % to about 1 mol % of RuO.sub.2 or hydrate thereof in the presence of about 3 equivalents of an oxidant to form the lactam compound with an enantiomeric excess of greater than or equal to about 95%.
Abstract:
A suboccipital pillow 10, for applying hot and/or cold treatments to the neck and suboccipital areas is provided, having a generally crescent shape, one side of which is fitted with a lightly insulated pocket 15a and the other side of which is fitted with a heavily insulated pocket 12a. Pillow 10 is filled with a soft cushion, such as a polyester fiber batting. Both pockets 12a and 15a have triangular tongues 16 and 17 attached to their open sides. Tongues 16 and 17 overlap and attach one to the other via a suitable fastener. A crescent shaped gel pack 21 is provided which may either be cooled in a refrigerator or freezer or heated in boiling water or in a microwave oven. After gel pack 21 has reached the desired temperature it is inserted in the appropriate pocket and the pocket is closed by overlapping and fastening the two tongues 16 and 17.
Abstract:
A fruit sub-sampler and grading table, especially for use with canning tomatoes, includes a frame. A measured supply of tomatoes is discharged at the entrance end of the frame and as it progresses toward the exit end of the frame is divided longitudinally into two streams. The first stream as it further advances is split to follow a primary path and a parallel but transversely spaced secondary path. Separate belt conveyors individually continue the two paths and are separately controllable as to speed by a pair of inspectors who transfer certain fruit from the belt conveyors to individual containers. These are disposed in the space between the conveyors and are supported on the frame by load cells connected to display individual container weights. Fruit discharged from the exit end of the belt conveyors is carried by a return conveyor toward the entrance end of the conveyor. Fruit in the second stream is discharged over a random selection drum. Fruit segregated by the drum is retained for special inspection, and the remainder of the second stream passing the drum is released to the return conveyor or is intercepted and discharged from the machine.
