Patent NO-20171644-A1 (NO)
Inventor: COSTO JR ROBERT JAMES
IPC: E21B47/10
Filed: 2017-10-17
Abstract: A method of operating a gas extraction system includes receiving a drilling fluid sample at a flow meter via a flow meter inlet conduit and discharging the drilling fluid sample into a flow meter outlet conduit. A first inline mud valve positioned in the flow meter inlet conduit and a second inline mud valve positioned in the flow meter outlet conduit are each closed to transition the gas extraction system to a bypass flushing configuration. A bypass flow meter valve positioned in a flow meter bypass conduit is opened to divert the drilling fluid sample around the flow meter. The flow meter is then flushed with flushing fluid by opening first and second flow meter flushing valves and starting a pump to circulate the flushing fluid through the flow meter.

Title: Apparatus for reproduction of television picture
Inventor: POWERS KERNS H
IPC: H04N5/44
Filed: 1982-09-08
Abstract: A flat-field television image having reduced visibility of horizontal scan lines is generated by receiving first and second fields of interlaced video and progressively generating a scanned image within a time for one incoming field. The progressively scanned image contains interstitital lines between the lines of one field, and consequently the line-scan structure is made less visible, but the flicker rate is undesirably decreased. In order to increase the flicker rate, additional progressively scanned images are generated at a rate equal to or greater than the incoming field rate.

Title: A method of a block production from a ceramic composite and a self-supporting structure of a ceramic composite,especially a gun tube
IPC: C04B35/65
Filed: 1987-09-10
Abstract: A method is provided of producing a self-supporting ceramic composite structure having one or more encasement members (14), such as an encasing stell sleeve, joined to it by growth of the ceramic material to engagement surface(s) of the encasement member(s) (14). A parent metal is contacted with a body of filler (38) which is encased by the encasement mmber(s) (14). The resulting assembly is heated to melt and oxidize the parent metal, e.g., aluminum, to form a polycrystalline material comprising an oxidation reaction product which grows through the body of filler (38) and stops at the engagement surface(s) of the encasement member(s) (14) which thereby determines the surface geometry of the grown ceramic matrix. Upon cooling, the encasement member(s) (14) is shrinkfitted about the ceramic composite body. The invention also provides the resultant articles, for example, a ceramic composite body having a stainless steel member affixed thereto.

Title: Condensation clothes drier
Inventor: JORDING WOLFHARD
IPC: D06F58/48
Filed: 2000-02-01
Abstract: The invention relates to a condensation clothes drier, comprising a rotationally mounted drying drum for receiving washing to be dried, a fan for conveying the process air that is required for the drying process, a fan for producing a cooling air flow by means of a heat exchanger, for dehumidifying the process air, a single driving motor for driving the drum and the process air and cooling air fans, and a programme control device with a device for controlling the driving motor. The aim of the invention is to configure a condensation clothes drier in such a way that the heating phase of the drying process is shortened in order to reduce the energy consumption of the drying process overall. To this end, the driving motor for driving the drum and for operating the process air and cooling air fans can rotate in alternate directions. The reversal of the direction of rotation of the driving motor from a starting direction of rotation with a reduced volume flow of cooling air determined by the construction of the cooling air fan to the preferential direction of rotation with a maximum volume flow of cooling air is controlled in dependence on the measured values detected by the sensor arrangement.
