Title: Coffee machine with product selectivity
Inventor: HELBLING EDWARD
IPC: A47J31/40
Filed: 1991-03-15
Abstract: ABSTRACT OF THE DISCLOSURE      A plurality of carafes on a coffee machine primarily for restaurant and institution use can be filled selectively with decaffeinated or normal coffee via a distributor between a brewing chamber and the outlets to the carafes.  The microprocessor controller operates the device selecting the coffee for delivery to the brewing chamber in response to signals received from the carafes if they are placed at respective stations on the machine so that a decaffeinated carafe at any station will receive only decaf and a normal carafe will receive only normal coffee regardless of the station at which it is placed.

Abstract: A variable speed pig for a pipeline includes a housing having at least one and preferably several flow through passageways. The size of the flow through passageways is varied according to the desired speed of the pig. The pig includes an annular seal disposed about the housing for sealing engagement with the pipeline and the housing, and the flow through passageways are selectively blocked by a first plate disposed in the housing, the first plate having a plurality of first openings . A second plate is also disposed in the housing, and the second plate has a plurality of second openings that are aligned in fluid connection with the flow through passageways . The first plate is movable in relation to the second plate from a position in which at least some of the first and second openings are in fluid connection to a position in which substantially none of the first and second openings are in fluid connection. The plates may be adjusted by a step motor and controller which are in turn controlled by a comparator circuit that compares the actual speed of the pig with the desired speed. The collective effective cross-sectional areas (size) of the flow through passageways is decreased when the actual speed is lower than the desired speed by more than the pre-set amount and increased when the actual speed is higher than the desired speed by a pre-set amount.

Abstract: 56,209 ABSTRACT OF THE DISCLOSURE A  mounting  ring  is  provided  which  adapts  an oversized exhaust flow guide to the existing inner cylinder of a steam turbine.  The mounting ring is comprised of six arcuate segments which allow the mounting ring to be radially installed into a groove, machined in the outer diameter of the inner cylinder, despite the presence of lugs which preclude axial installation.  The mounting ring and exhaust flow guide form a moisture removal gap just upstream of the tips of the last  row rotating blades.   Arcuate  filler   segments  are installed in the vicinity of the horizontal joint to create a uniform moisture removal gap around the circumference of the steam flow path.  The mounting ring creates an access space above the horizontal joint flanges in the cover half of the inner cylinder for installation of the horizontal joint bolts.

Title: Planetary-gear train for hybrid-drive vehicles
Inventor: KUTTER MICHAEL
IPC: F16H3/72
Filed: 1991-06-10
Abstract: ABSTRACT OF THE DISCLOSURE      In the planetary-gear train proposed, a sun gear (3) is indirectly mounted via a bushing (15) on a central shaft (1) with a centered flange (2).  The sun gear meshes with several planet gears (4) which are secured by screws (12) to the planet-gear carrier (5) and to the flange (2), and hence to the shaft (1).  The planet gears (4) mesh in turn with internal toothing (6') on a bell-shaped element (6) which is mounted on the shaft (1) and which represents the crown gear of the planetary-gear train.  Mounted on the outside of the bell-shaped element are the various sprocket wheels of a chain-change sprocket assembly (9) via which muscle power can be added to that of the planetary-gear train crown gear.  The drive is transmitted through the planet-gear carrier (5), which is designed as a mounted ring for a disc wheel (10). The gear train proposed requires little space, is simple in design and, at typical travel speeds, no energy losses due to rolling motion are incurred since under these conditions the sun gear and the crown-gear turn synchronously and the planet gears therefore stay still.

Abstract: 0143R                                            Docket No. 91H987 ABSTRACT OF THE INVENTION      A filter having a microporous hydrophilic membrane is utilized in a thermodilution set up wherein the filter is positioned downstream from the injectate reservoir, the syringe and most of the fittings through which bacteria or other harmful materials could enter the bolus of injectate.  The filter thus traps bacteria and particulates and prevents the material that may have inadvertently entered the injectate stream from being introduced into the patient.  The filter is relatively inexpensive and is commercially available having a pore size of about 0.2 um while allowing typical thermodilution injactate flows of about 150 cc/min.
