IPC: A61M5/158
Filed: 1994-08-31
Abstract: A trocar and catheter assembly for automatically disarming the trocar after placement of the catheter into a patient's blood vessel includes a spring urging retraction of the trocar and a releasable retainer mechanism for maintaining the trocar in an extended position during insertion of the catheter into the blood vessel. In one embodiment, the catheter is removably mounted to a handle which defines an internal passage.  Disengaging the handle from the catheter after placement of the catheter into the blood vessel actuates the releasable retainer mechanism for allowing the trocar to be drawn into the handle passage under the influence of a spring, to enclose the sharpened end of the trocar after use. In another embodiment, the insertion device is in the form of a pair of wings which are movable between a closed position and an open position. The wings are in their closed position and grasped by the user when inserting the catheter into the blood vessel, and are thereafter moved to their open position.  Movement of the wings to their open position actuates the releasable retainer mechanism, and the trocar is then drawn rearwardly so that its sharpened end is drawn into the catheter passage under the influence of the spring.

Title: Dehydration of acetic acid by azeotropic distillation in the production of an aromatic acid
Inventor: PARTEN WILLIAM DAVID
IPC: C07C51/265
Filed: 1995-08-16
Abstract: In a process for production of an aromatic di--carboxylic acid such as terephthalic acid by the liquid phase oxidation of a precursor (e.g. p-xylene) thereof, an overheads stream (10) comprising aqueous aliphatic carboxylic acid is subjected to azeotropic distillation in column (12) to reduce the water content. The azeotropic distillation may be carried out using reflux of the entrainer only (22) with control of entrainer penetration to obtain a bottoms product (34) which is substantially entrainer free and contains a predetermined amount of residual water. Any aromatic dicarboxylic acid precursor present in the overheads stream is separated from the aliphatic carboxylic acid by withdrawal at a location (24) in the vicinity of the point of introduction of the feed (10) into the column. The amount of water in the bottoms product (34) may be controlled by regulation of a separate water feed (76) to the lower section of the azeotropic distillation column. In addition, regulation of the reflux rate (via line 22) may be employed to control the water content of the bottoms product and maintain column operation in the event of loss of feed to the column.

Date May 15, 1997A process is provided for reducing the amount of hydrogen sulfide present in a tail gas from a sulfur recovery process. The hydrogen sulfide contaminated gas along with a gas containing free oxygen is passed through a series of hydrogen sulfide oxidation zones containing an oxidation catalyst, such as one or more oxides or salts of Ni, Co, Fe, Cu, Ag, Mn, Mo, Cr, W and V, deposited on a support, such as bauxite, activated alumina, titania and activated carbon. The initial and intermediate catalyst beds are operated adiabatically by injecting a substoichiometric amount of oxygen into the gas to be treated with respect to the amount of hydrogen sulfide present in the gas so that the temperature does not exceed 150 DEG  C. The final catalyst bed is operated under conditions such that a superstoichiometric amount of oxygen is injected into the gas with respect to the hydrogen sulfide and cooling is provided so that the temperature does not exceed 150 DEG  C. The invention is able to maintain an optimum selectivity toward sulfur during the catalytic oxidation of the hydrogen sulfide by controlling the temperature.
