Patent FI-98814-C (FI)
Inventor: ANDERSON NEAL G
IPC: C07D207/16
Filed: 1990-11-05
Granted: 1997-08-25
Abstract: A process is disclosed for direct isolation of captopril from a substrate of the formula <CHEM> wherein R is lower alkyl or lower alkoxy. In this process, the substrate is first treated with an aqueous alkali metal hydroxide capable of forming a water-soluble salt of the substrate, wherein the alkali metal hydroxide has a concentration of 4 M or greater. The substrate is then neutralized, preferably with a mineral acid. By this process, captopril may be directly crystallized from an aqueous solution, avoiding the prior art use of organic solvents and zinc treatment to reduce levels of sulfide and disulfide impurities, respectively. In an alternative embodiment, neutralization is carried out by use of a hydrogen-supplying ion exchange resin.

Abstract: The present invention concerns a means for controlling and/or measuring the flow of a running fluid, wherein the throttling of the flow is controlled utilizing the fluid's own differential pressure arising from the flow. The valve comprises a cover provided with a flow aperture, a main valve disc and control means consisting of a cylinder volume/piston assembly, the movement of said piston being connected to the main valve disc, and wherein the cylinder volume has been connected by a first opening (d1 min ) to the high pressure side and by a second opening (d2 min ) to the low pressure side so that the ratio of the areas of the openings is adjustable. The means comprises at least one sensing member by the aid of which the position of a part of the cylinder volume/piston assembly moving axially in the direction of the flow is measured; a data processing unit, to which the signal from the sensing member is conveyed after appropriate processing; a memory unit, in the first part of which have been stored data concerning the characteristic curve of the valve or equivalent, from which based on the signal from said sensing element, with the aid of the data processing unit, the variations of volumetric flow and or pressure can be calculated, and in the second part of said memory unit being stored the desired values of the volumetric flow and/or pressure, with which the calculated values mentioned before are compared; and at least one actuator by the aid of which the ratio of areas of the openings (d1 min , d2 min ) is adjustable for realizing the desired volumetric flow and/or pressure.

Title: Facsimile service
Inventor: CATRON NANCY A
IPC: H04M3/54
Filed: 1990-01-24
Granted: 1994-01-04
Abstract: Abstract This invention relates to methods of establishing facsimile (fax) connections. If a call is originated from a fax source and the destination is a voice station, then the call will be automatically redirected to a fax machine designated to receive fax messages for the voice station. A fax call is detected by a class of service indication in a local switching office, or by having a number forwarded to a toll office from a local office by Automatic Number Identification (ANI) of the caller that is one of a list of fax numbers. When it is determined that a call is a fax call, a fax indicator is sent with Common Channel Signaling (CCS) messages for that call. If a call with a fax indicator is received in a destination switching office, then the destination office checks to see if the called number is a fax number, if not, translation is made to find the number of a fax station for serving fax calls to the called number, and the call is completed to that fax station. Advantageously, customers need not know a fax number to transmit a fax message to an intended recipient.

Title: Expandable obturator and catheter assembly including same
Inventor: SOLOMON DONALD D
IPC: A61M25/00
Filed: 1990-06-05
Granted: 1996-06-04
Abstract: An  obturator  includes  a  solid  substantially stiff rod of a nonhydrophilic polymer coated with a layer of a hydrophilic polyurethane which may have an antithrombogenic agent bulk distributed therein.  When the hydrophilic polyurethane comes into contact with an aqueous  liquid such as water,  saline or  a body fluid,  it  absorbs  the  liquid  and  expands  thereby enlarging  the  diameter  of  the  obturator.   Another aspect of the invention is an assembly of a catheter and  the  obturator  of  the  invention.    When  the obturator is emplaced in the catheter and brought into contact  with  a  liquid,  it  expands,  releases  the antithrombogenic agent and contacts the lumen wall of the catheter thereby forming a  seal  which  prevents backflow of a body fluid.

Title: Remote control modification for manually controlled hydraulic systems
Inventor: ST MARTIN LOUIS G
IPC: F01B25/02
Filed: 1990-06-21
Granted: 2000-06-27
Abstract: A remote control modification (11) for a hydraulic steering system (13) of the type used to steer underground loaders and the like is disclosed. The remote control modification comprises a bidirectional, spring-loaded remote control valve (51) connected in parallel with the bidirectional, spring-loaded control valve (19) that normally responds to steering inputs created by the manual movement of a steering arm (25). The remote control valve (51) has outlet ports (75 and 77) that are smaller than the outlet ports (39 and 41) of the manual control valve (19). Movement of the piston of the remote control valve (51) is controlled by a slave hydraulic actuator (53). The flow of hydraulic fluid to the slave hydraulic actuator (53) is controlled by a solenoid-actuated valve (59).  The solenoid (61) of the solenoid-operated valve (59), in turn, is controlled by a receiver (63) that responds to radio frequency control signals (105) generated by a remotely located transmitter (65). Located in the hydraulic lines between the solenoid-operated valve (59) and the slave hydraulic actuator (53) are restrictor/reverse bypass pressure relief valve combinations (55 and 57).  Finally, preferably, the hydraulic line running to the larger capacity chamber of the slave hydraulic actuator (53), i.e., the non-shaft chamber, is coupled to the hydraulic return tank via a relief line that contains a manually adjustable restrictor valve (67).

Abstract: The pointer of an air-core meter instrumentation gauge comprises a driven hub via which the pointer is reparably attached to a driving hub on the rotor of the air core meter movement. The driving hub is press-fitted to the rotor in proper circumferential alignment so that when the pointer is attached, the pointer will be inherently properly circumferentially oriented too.  This is accomplished by providing a keyed connection between the driving and driven hubs such that the pointer can be assembled to the driving hub in only one particular circumferential orientation. The hubs also have a snap-together catch feature that is additional to the keyed connection.
