Abstract: Abstract of the Disclosure A method and apparatus for electropolishing or chemical polishing the entire inner surface or portion of a large cylindrical vessel having at least one closed end.  The vessel is supported for rotation with its longitudinal axis in an inclined position and its lower end provided with axial thrust support.  The polishing liquid is introduced into the vessel in a quantity sufficient to attain a surface level as high as the center point X of the lower closed end.  The vessel is then rotated about its inclined axis and the entire inner surface of the lower end is polished.  The vessel is then repositioned with the unpolished end being lower than the previously polished end and supported in the same manner.          The level of the polishing liquid is then adjusted so that the remaining unpolished inner surface will be wetted and polished upon the rotation of the vessel about its in-clined longitudinal axis.  The vessel is then so rotated while polishing is completed.

Abstract: ABSTRACT OF THE DISCLOSURE          In heating time control apparatus for microwave oven, it is known to have a humidity sensor for detecting a humidity generated from a food stuff to periodically interrupt the heating of the food stuff thereby to prevent overheating.  In this invention, a total heating time T0 which consists of a first heating time period T1 and a second heating time period T2 is automatically determined.  The first time period T1 is measured from the application of power to the magnetron until a humidity sensed by the humidity sensor reaches a predetermined value and the second time period T2 corresponds to the product of the first time period T1 and a heating time coefficient k determined by the type and quantity of food stuff to be heated in a microwave oven.  A heating time period optimum to the type and quantity of food stuff can be automatically determined without using a timer device.

EVERT                       SLACK TAPE LOADER                            ABSTRACT    A slack tape loader for a tape transport apparatus has a signal generator selectively energized by a tape loading control switch to produce an enabling signal for a reel motor control servo circuit.  The enabling signal has a duration which will energize the reel motor control servo for a short period of time to load the slack tape on tape storage reels.          Concurrently, the tape transport is operative to detect a tensioned state of the tape.  The enabling signal is recurrently produced by the signal generator in response to the tape loading control switch until the desired tape tension is detected by a tape tension sensing means to produce an output signal for disabling the signal generator.

Abstract: RECORD MEDIUM, METHOD OF MAKING SAME, AND METHOD AND APPARATUS FOR RECORDING INFORMATION ON AND REPRODUCING INFORMATION         FROM SAID RECORD MEDIUM           ABSTRACT OF THE DISCLOSURE    A novel record medium, its method of manufacture, and a method and apparatus for recording information on and reproduc-ing information from said record medium are disclosed.  The record medium comprises a disc-like body having a surface pro-vided with a first portion adapted to have signal information recorded thereon and a circular track distinct from the first portion having reference information therein.  When used to record signal information in the first, or signal information portion thereof, the record medium is rotated about an axis while the signal information is recorded thereon.  The refer-ence information in the circular track is predetermined, detectable pattern which is sensed while the record medium ro-tates.  In the event of eccentric rotation, the record medium undergoes a lateral displacement with respect to a center, or drive shaft, whereby the circular track is shifted with respect to a fixed pattern detecting station.  This, in turn, results in a relative shift in the detectable pattern whereby the eccentric rotation is sensed.  The signal recording apparatus is adjusted in response to sensed eccentric rotation so as to compensate for such rotation.  Similarly, when the record medium is used for the reproduction of previously recorded information, eccentric rota-tion of the medium is sensed by detecting a shift in the detect-able pattern provided in the circular track so as to correspond-ingly adjust the signal playback apparatus to compensate for such eccentric rotation.                             -i-

Abstract: A B S T R A C T               A directional hot film anemometer transducer for sensing the speed and direction of a fluid velocity vector that describes the motion of the fluid in which the transducer is immersed.  The trans-ducer is constructed of two cylindrical resistive electrical conductors which are mounted on either side of a third cylindrical member that is used for mechanical support and which also may be used as a blas-ing heated resistive electrical conductor so as to improve this spatial directional response of the three element transducer.  The three cylin-drical elements are supported so as to maintain their axes within a single plane and are joined by bridging means which provides a de-gree of thermal isolation between the conductors in order to facilitate the determination of instantaneous fluid flow direction.  The bridg-ing means is primarily intended to close the aerodynamic path between the conductors so that the transducer array functions as a single con-stant temperature element when the array is excited by an appropriate constant temperature anemometer electronic control system electri-cally coupled to each conductor of the tranducer array.  The electri-cal conductors can be metallic or resistive films which are deposited ed on a cylindrical supporting body.  Each conductor which is actively used within the transducer array is made of a material which exhibits a change in its electrical resistivity as a function of temperature. Electrical connections are provided on each end of each conductor to permit each conductor to be separately heated by its own electrical current.  The conductors in the transducer array may be fabricated in the form of a cantilever or single ended device.
