Abstract: The present invention describes compounds produced from an orotic acid molecule and an amino acid molecule. The compounds being in the form of amino acid orotate compounds bound by an amide linkage and produced by one of two disclosed methods; 1) reacting orotic acid or derivatives thereof with a thionyl halide, and then combining the acyl halide with an amino acid in the presence of dichloromethane and a DMAP catalyst; or 2) protecting the carboxylic acid of an amino acid and then combining the amino acid with a DCC activated orotic acid, followed by removal of the carboxylic acid protecting group. The resulting amino acid orotate amide has an enhanced stability in solution as compared to a related ester. In addition, specific benefits are conferred by the particular amino acid used to form the compounds in addition to, and separate from, the orotate substituent.

Abstract: This pushchair when folded has its sides being brought closer together and the rear wheels spaced away with respect to the front wheels, the support of the rear wheels having a pin-jointed connection allowing to fold it with respect to the corresponding leg. A characterizing feature of this pushchair lies in the fact that each of the supports of the rear wheels has a second pin-jointed connection below its pin-jointed connection linking it to the corresponding leg, this allowing to increase the degree of folding of the actual support when folding the pushchair. The supports of the rear wheels form two lengths being linked to each other in a pin-jointed connection and are articulately linked to component members of the chassis of the pushchair which when carrying out the folding of this latter pull the two lengths of said supports in order to thus bring about the folding of the rear wheels.

Granted: 2014-07-08
Abstract: A humidifier for use with a pressure support system. The humidifier includes a body (44, 302, 442, 910) having an inlet (36, 308, 448, 914), a fluid holding chamber (46, 318, 454, 912), and an outlet (40, 916). The inlet is positioned upstream and in fluid communication with the fluid holding chamber. The outlet is positioned downstream of and in fluid communication with the fluid holding chamber. A back-flow preventing valve (60, 160, 260, 304, 334, 400, 444, 500, 600, 700, 760, 902, 930, 958, 970, 980) is positioned upstream of the fluid chamber. The back-flow preventing valve is movable between an open position, in which the inlet is unblocked, and a closed position in which the inlet is blocked. In the closed position, the back-flow preventing valve prevents fluid, fluid vapor, or both from entering the pressure support via the inlet to the humidifier.

Title: Rake receiver with variable bandwidth in order to minimize guard bands
Inventor: SAHLMAN KARL GOESTA
IPC: H04L27/00
Filed: 2006-10-12
Granted: 2014-07-22
Abstract: A variable bandwidth receiver (30) uses allocated bandwidth more efficiently and ensures that blocking signals do not overload receiver components. The receiver includes multiple branches (34a...34n) for receiving a first bandwidth signal. Each receiver branch has a filter (48a.. .48n) for passing signals in a frequency band corresponding to a second bandwidth less that the first bandwidth and an analog-to-digital Converter (58a...58n) for converting the baseband signal into a digital signal. A Controller (36, 60) digitally combines the digital signals from two or more of the receiver branches to produce a received signal having a bandwidth substantially wider than the first bandwidth. Because combining is done after analog-to-digital conversion in the digital domain, the Controller can combine the digital signals from two or more of the receiver branches having adjacent corresponding frequency bands without the normal guard band separating them.

Title: Disc implant
Inventor: CHRISTENSEN FINN BJARKE
IPC: A61F2/44
Filed: 2006-12-08
Granted: 2014-04-08
Abstract: A problem with total disc implant surgery appears to be the positioning of the implant which if not correct may lead to pain and eventually new surgery. The present invention relates to an improved disc implant (1) for total disc replacement, comprising two inter- vertebral elements (2) which are flexibly connected via coupling means (4,5). Following surgery, the relative movability of said two inter- vertebral elements is decreased overtime, as bone ingrowth occurring around the implant and specifically through osseointegrative sections gradually degrease the movability of the elements relative to each other. Following, the relative movability of the implant elements is replaced by fixation of the elements. The fixation has flowingly occurred in a position affected by the movement of the patient, and is thereby more acceptable to the patient.
