20100251906 | SALAD SPINNER - A rotatable greens drying device that includes a lid, a rotatable colander, a drive mechanism for rotating the colander, and a receiving ring fan which transfers rotational force from the drive mechanism to the rotatable colander. The fast moving, drier air circulated by the receiving ring fan naturally helps evaporate moisture from the surface of the greens and it helps expel water through container holes. This embodiment also allows air exposure of the leafy contents via the perforations within the spinning colander which further reduces surface moisture. | 10-07-2010 |
20130213319 | PET HARNESS FOR ASSISTING PET MOBILITY - The invention presents a harness assembly for lifting and supporting an animal in mobility. The assembly comprises a front and rear harness sections releasably attached by a lifting leash. Both the front and rear harness sections can be used independently. Both the front and rear harness sections are comprised of upper and lower sections releasably attached to one another. The rear harness section lifts the animal from both the hips and waist resulting in less stress than other devices. | 08-22-2013 |
20140033987 | MODULAR ANIMAL EXERCISE STRUCTURE - A modular play structure for animals has base and platform pieces with connector mechanisms, such countersunk bores, spaced apart by a standard distance. Thus platforms and bases can be oriented in multiple directions and are interchangeable. Columns space the bases and platforms vertically. Columns may be of varying height, preferably with different heights described by a common factor. Stacked columns are connected end-to-end with a spacer of the same thickness as a platform interposed therebetween. Columns are oriented in the same direction with female and male ends connecting with platform, base, and adjacent columns. | 02-06-2014 |
20140338546 | SALAD SPINNER WITH ANGLED BLADE FAN - A salad spinner has a support frame with a receiving aperture. A colander is supported by the support frame in the receiving aperture for rotation about an axis of rotation. A removable drive assembly is removably coupled to the support frame and colander, and the removable drive assembly includes an actuator to transmit a driving input applied to the actuator to rotate the colander. A fan having a plurality of angled blades is mechanically coupled to the actuator to force air into the colander. | 11-20-2014 |
20150374174 | SALAD SPINNER BRAKE MECHANISM - A salad spinner has a hub connected in a rotary driving relationship to a colander mounted within the salad spinner for rotation about an axis of rotation. A brake provides braking force to the hub coaxially with the colander axis of rotation. | 12-31-2015 |

20120272033 | System and Method for Managing Space Allocation within a File System - A chassis management controller includes a root file system, a shared memory, a daemon process module, and an interposer library. The root file system includes a plurality of directories associated with firmware applications of the chassis management controller. The daemon process module is configured to read the parameters of the directories, and to create, in the shared memory, a table including parameters of the directories. The interposer library is configured to intercept an input/output library call for an operation associated with one of the firmware applications, to read table entries associated the one or the firmware applications, to determine whether the operation associated with the input/output library call would result in an over-allocation of a parameter in the entries of the table, and if the operation would not result in the over-allocation, pass the output operation to a standard system library, otherwise to return an out of space error message. | 10-25-2012 |
