The distal anchor is reconfigurable from the delivery configuration to a deployed configuration.
Abstract:
The present invention relates to a separation process for removing acetone from a mixture comprising acetone, methyl acetate and methyl iodide, said process comprising the steps of: (a) introducing said stream comprising acetone, methyl acetate and methyl iodide into a first distillation zone; (b) introducing acetic acid into said first distillation zone, either by addition of acetic acid to said stream comprising acetone, methyl acetate and methyl iodide or by introduction of acetic acid directly to the first distillation zone at one or more points at or above the point of introduction of said stream comprising acetone, methyl acetate and methyl iodide into the first distillation zone in step (a), or a combination of both; (c) removing from the first distillation zone an overhead stream comprising methyl iodide and a bottoms stream comprising acetone, methyl acetate, acetic acid, and a reduced amount of methyl iodide; (d) introducing into a second distillation zone the bottoms stream from step (c); (e) removing from the second distillation zone an overhead stream comprising methyl acetate and methyl iodide and a bottoms stream comprising acetone, methyl acetate and acetic acid; (f) introducing the bottoms stream from step (e) into a third distillation zone; and (g) removing from the third distillation zone an overhead stream comprising methyl acetate and acetone and a bottoms stream comprising methyl acetate and acetic acid.

A system for detecting hydrocarbons includes a processor and a memory, wherein the memory comprises a program having instructions for: obtaining seismic trace data for a region of interest; and processing the seismic trace data to calculate a Smooth Signal Spectrum for each of a plurality of locations in the region of interest.
Abstract:
A bariatric device and method of causing weight loss in a patient includes providing a bariatric device having an esophageal member, a cardiac member and a connector connected with the esophageal member and the cardiac member. The esophageal member has an esophageal surface that is configured to generally conform to the shape and size of a portion of the esophagus. The cardiac member has a cardiac surface that is configured to generally conform to the shape and size of a portion of the cardiac portion of the stomach. The esophageal surface is positioned at the esophagus. The cardiac surface is positioned at the cardiac portion of the stomach. The bariatric device stimulates receptors in order to influence a neurohormonal mechanism in the patient.
Abstract:
An apparatus and method are provided for performing integrity checking of software code executing on a processing unit of the apparatus. The apparatus further includes debug logic used when debugging program code executed by the processing unit, and trusted logic for performing trusted integrity checking operations on less- trusted program code executed by the processing unit. The debug logic has an interface via which the trusted logic can program one or more control registers that interface not being accessible by the less-trusted program code. The trusted logic programs the control registers so as to cause the debug logic to be re-used to detect one or more activities of the processing logic during execution of the less-trusted program code, and the trusted integrity checking operations performed by the trusted logic are influenced by the activities detected by the debug logic. Such an approach has been found to provide an efficient and secure technique for performing run-time integrity checking of program code.
Abstract:
A cap (100) is provided that includes a crown (102) that is substantially hemispherical in shape and configured to receive the head of a wearer. The cap (100) also includes an unfolded sweatband (110) connected to the inside bottom edge of the crown. The sweatband (110) is preferably unfolded and constructed from the same material used to construct the crown (102). The sweatband (110) can include a front portion (112) and a back portion (114), which are connected by a seam cover (116).
Abstract:
Described is a mixing tool for mixtures of solids or individual solids. The tool is fixed to a shaft (11) located inside a horizontal container (12) so that the shaft is concentric with the container. The shaft (11) is fitted in the container (12) so that it can rotate. Several mixing tools (10) can be fixed at intervals along the shaft. The mixing tools (10) extend out radially towards the inside wall (13) of the container and end a short distance from the inside wall (13) of the container. Each mixing tool (10) has a first mixing element (15) and a second mixing element (16) which are mounted on an arm (14) one behind the other in the direction of rotation. The ends of the mixing elements (15, 16) nearest the inside wall (13) of the container have cut-out sections (19, 19', 19'', 20, 20'). The cut-out sections (19, 19', 19'') in the first mixing element (15) are staggered with respect to the cut-out sections (20, 20') in the second mixing element (16). When viewed from the front, the projecting sections (21, 21') of the first mixing element (15) mask the cut-out sections (20, 20') of the second mixing element (16).
Abstract:
An anti-theft device (1) to prevent the unauthorised use and/or deter theft of an audio cassette player/recorder or video player/recorder or the like. The anti-theft device comprises an insertable portion (12) adapted to slide within the cassette or disc housing and a non-insertable portion (4) adapted to abut the periphery of the cassette or disc housing. A lock means (2) is provided in the non-insertable portion (4), operable by key (6) or the like. A locking shaft (3), having a protruding portion (9) extends therefrom which is adapted to be engaged in a first unlocked position end a second locked position. The locking shaft (3) is embodied with a first end operatively connected to said lock means (2) a second and extending into said insertable portion (12) and, a central portion of substantially circular cross-section, being threaded on an external surface (7) thereof, and having a slide bed (8) cut therethrough. A correspondingly shaped locking pin (9) is adapted to slide within said slide bed (8) and be firmly locked into position therealong by means of a pair of locking nuts (10, 11) adapted to engage said threaded external surface (7), one on either side of said locking pin (9).
Abstract:
Contaminated liquid, such as lubricating oil, if necessary diluted, is caused to flow down a channel formed by a trapezoidal section groove in a white plastics sample plate (6) which is supported on a stand (2) with the groove sloping downwards in a magnetic field created between pole-pieces (11) on a horse-shoe shaped permanent magnet (10). The liquid sample is supplied to the upper end of the groove by a funnel (15). Any remaining liquid in the groove is gently flushed away with solvent and the deposit left in the groove is visually compared with standard sample plates previously prepared from liquids of known contamination.
