Title: Synthesis of cyclohexane derivatives useful as sensates in consumer products
Inventor: YELM KENNETH EDWARD
IPC: A61K8/41
Filed: 2009-08-13
Abstract: The present invention provides synthetic routes for preparing various isomers of cyclohexane-based coolants, such as menthyl esters and menthanecarboxamide derivatives, in particular those substituted at the amide nitrogen, for example with an aromatic ring or aryl moiety. Such structures have high cooling potency and long lasting sensory effect, which make them useful in a wide variety of consumer products. One synthetic route involves a copper catalyzed coupling of a primary menthanecarboxamide with an aryl halide, such reaction working best in the presence of potassium phosphate and water. Using this synthetic route, specific isomers can be prepared including the menthanecarboxamide isomer having the same configuration as l-menthol and new isomers such as a neoisomer having opposite stereochemistry at the carboxamide (C-1) position. The neoisomer unexpectedly has potent and long lasting cooling effect. Preparation schemes for neoisomers of other menthyl derivatives which are useful as coolants, including esters, ethers, carboxy esters and other N-substituted carboxamides are also provided.

Abstract: Systems and methods integrate disparate backup devices with a unified interface. In certain examples, a management console manages data from various backup devices, while retaining such data in its native format. The management console can display a hierarchical view the client devices and/or their data and can further provide utilities for processing the various data formats. A data structure including fields for storing both metadata common to the client device data and value-added metadata can be used to mine or process the data of the disparate client devices. The unified single platform and interface reduces the need for multiple data management products and/or customized data utilities for each individual client device and provides a single pane of glass view into data management operations. Integrating the various types of storage formats and media allows a user to retain existing storage infrastructures and further facilitates scaling to meet long-term management needs.

Abstract: An armrest is movable between a stowed position disposed within a recess of a seat back and a deployed position extending from the recess. A bracket fixedly secured to the seat back includes a slot having an angled portion connected with a vertical portion, which is connected with an arcuate portion. First and second pins extend laterally from a proximal end of the armrest and are pivotally and slidably coupled to the slot. The first pin travels along the angled portion and the second pin travels along the vertical portion in response to pivotal movement of the armrest, thereby lifting the armrest to prevent interference between the proximal end of the armrest and the seat back. The first pin remains at the transition between the angled portion and the vertical portion and the second pin travels along the arcuate portion in response to further pivotal movement of the armrest.

Abstract: A patient lift including a boom (18)s a spreader bar (20), an a friction coupling (50, 100, 120, 150, 200, 250) for securing the boom (18) and the spreader bar (20). The friction coupling consists in one embodiment of two friction washers disposed against respective inner faces of the boom (18). Two compression springs are disposed abutting the friction washers with a spreader bar support member in between. The compression springs urge the friction washers against the inner faces of the boom end. The spreader bar does not swing when the lift is moved without load. Also, the friction coupling reduces the swing of the patient, when transferred in the lift. This makes the lift easier to manoeuvre for the caregiver.
