Title: Acetone separation by extractive distillation
Inventor: ERPENBACH HEINZ
IPC: C07C45/80
Filed: 1982-09-10
Granted: 1986-02-20
Abstract: The disclosure relates to a process for separating acetone from reaction mixtures originating from the reaction of methyl acetate and/or dimethylether with carbon monoxide and optionally hydrogen in the presence of a catalyst system consisting of carbonyl complexes of noble metals of group VIII of the Periodic System of the elements, acetic acid, an organophosphorus or organonitrogen compound, methyl iodide and optionally carbonyl-yielding compounds of common metals. To this end, the disclosure provides for the reaction mixture containing acetic anhydride, acetic acid, ethylidene diacetate, methyl iodide, acetone and methyl acetate which is distilled off from the catalyst solution, or just its low boiler fraction consisting of methyl acetate, methyl iodide and acetone to be subjected wholly or partially to an extractive distillation with acetic acid and for pure methyl iodide to be distilled off; for an acetone/methyl acetate mixture to be distilled off from the acetic acid extract; for this mixture to be separated in known fashion and for the acetic acid extractant to be recycled into the extraction stage, if desired after separation of the final reaction products comprised of acetic anhydride; ethylidene diacetate and acetic acid.

Title: Bioavailable composition of natural and synthetic HCA
Inventor: MAJEED MUHAMMED
IPC: A61K36/18
Filed: 2001-08-17
Granted: 2004-05-13
Abstract: The invention relates to a composition comprising hydroxycitric acid (HCA) in combination with either one or both of garcinol and anthocyanin, and its use as a weight-loss therapy in animal subjects, preferably humans. The therapeutic effects for the composition observed in murine and human studies include a reduction in total body weight and body mass index, a reduction in body fat, an increase in lean body mass and content of body water, and a reduction in perceived appetite level. Another composition for use in weight-loss therapy is also described relating to forskolin in combination with either one or both of garcinol and anthocyanin. The anti-oxidant properties of garcinol are described as being enhanced in the presence of HCA and anthocyanin, and the combination of HCA, garcinol and anthocyanin is also shown to exert greater citrate lyase inhibiting properties than either compound alone. Methods of obtaining HCA, garcinol or anthocyanin, or a composition containing all three compounds, are described.
Patent BG-60235-B2 (BG)
Title: Device for offsetting the slope of past-going transport vehicles, especially for rail track vehicles
Inventor: SCHNEIDER RICHARD
IPC: B61F5/24
Filed: 1990-06-12
Abstract: The device is used for offsetting the inclined position of the carriage of the rail vehicle when running on a bend at high speeds using a passive system of sloping. It includes a pivoted four-link unit (4), coupled to an energy battery (49) inclining the carriage (1) of the waggon inwards of the curvature of the bend. The carriage (1) of the waggon rests on a supplementary lateral suspension (23) and gets into it without restricting the lateral inclination of the contour (61) of the waggon carriage in a preset limitation profile. In this way, when running on a bend, the tendency of the waggon carriage to incline outwards from the bend curvature is offset by the energy battery (49).

Patent DE-2005322-B2 (DE)
Title: Recognition of end of number selection - by employing decoder of incoming calls to give end signal for push-button dialling code
IPC: H04Q3/62
Filed: 1970-02-06
Abstract: The dialling circuit is applicable to telephone systems with push-button number election. The selection of a number outside the private exchange is stored in unit digit form and released to a converter for transformation into a series of impulses. The coded signal then passes to an output unit and into the outgoing line. In the output unit a branch feeds the impulse coded signal to a converter which changes each impulse series back into a unit code which is then applied to the converter for incoming calls. Here a digit count is carried out and through routing switches a signal passed to the 'end of number' signal generator to reset the converter and open the line for speech transmission.

Filed: 1972-04-17
Abstract: An auxiliary voltage from supply (10) is brought to the adder circuit (11) of the integrating amplifier (1), the output voltage increasing with a velocity corresponding to the adjusted time constant. The output voltage is compared in comparison circuit (6), according to selection, with one of the voltages gained from the outputs (51 or 52) of the high-voltage rectifier, namely with the voltage indicating the d.c. output voltage value of the high-voltage rectifier (5) or with the standard d.c. voltage indicating the d.c. output current value of the high-viltage rectifier (5). The difference between one of these voltages and the output voltage from the integrating amplifier (1) is amplified by an operation amplifier and appears as output voltage at the output (64) of the comparison circuit (6).

It attains the liquids in an upper layer and a lower layer in the primary bag to flow in relevant satellite bags by detecting the position of an intermediate layer in the primary bag by means of an interface detecting member, continuously measuring the weight of the primary bag by means of a weight measuring unit, and continuing the open-shut control of clamp members thereby enabling the intermediate layer to remain in the intermediate position in the primary bag. <IMAGE>
Patent JP-S6225848-B2 (JP)
IPC: F01M13/00
Filed: 1982-02-08
Abstract: PURPOSE:To improve the lubrication performance by introducing a breezer passage around the crankshaft on the upper bearing of a vertical engine so as to allow the breezer air stream to flow into said flow passage and feeding the lubricating oil separated from said air stream into the upper bearing from the upper part. CONSTITUTION:A through-hole 5 which communicates to the upper part of an upper bearing 3 is formed on a crankcase 2, and the lubricating oil projected from a lower lubricating oil sump by an oil slinger is received through the through-hole 5, thus an upper bearing 3 is lubricated. An air-flow is generated from a crank chamber 1 to the outside after passing through the breezer passage, being caused by the reciprocative movement of the piston of an engine. The oil mist in the crank chamber is transported by said air stream, forced to rush into an annular space,after passing through the through-hole 5, collide with the upper extension part 4b of a crankshaft and the inner wall of a sleeve 6, and adhere onto  inner wall. Said oil flows down in the form of oil droplets, which lubricate the upper bearing 3.
