Title: Method and apparatus for pouring a mold with a selectable amount of casting material
Inventor: BUEHRER ERWIN
IPC: B22D39/00
Filed: 1977-03-14
Granted: 1980-02-26
Abstract: ABSTRACT OF THE DISCLOSURE       The amount of liquid metal casting material poured into a mold from a receptacle located above the mold from pouring means in the bottom of the receptacle is controlled by continuously sensing the pressure head of the liquid metal casting material in the receptacle during pouring or the mold, numerically integrating to a constant value the product of the multiplication of a function of the pressure head and time, and controlling the pouring means to terminate the pouring of the mold when a predetermined set value is attained.  Electronic control circuitry receives as an input signal a signal representing the pressure head of the liquid casting material within the receptacle and a control function is effected by the electronic control means to stop pouring when a selected predetermined amount of material has been introduced into a mold.  The quantity of casting material poured into a filled mold is sensed and a feedback signal is provided to adjust the control function when the amount of casting material in the filled mold is found to deviate from a desired amount.  The electronic control circuitry includes manual presetting means whereby such adjustment may be effected.  Furthermore, since the pouring mechanism in the bottom of the receptacle may be subject to variations which could change the pouring characteristics, the electronic control circuitry may be equipped with a mechanism to sense such variations in the rate of flow of the pouring device and adjust for changes.  This adjustment mechanism may include a device for sensing differences in the pouring rate, and a device having programmed thereinto a given value, with a comparison between the rate actually sensed and the programmed value operating to determine the difference therebetween whereby adjustments of the pouring rate may be effected.

Abstract: ABSTRACT OF THE DISCLOSURE:         Demisting device for the rear window of a passenger car.  It is made up of a sheet carrier over which are applied a series of electrically conductive tapes.  Each tape is formed of an aluminum strip connectable to a source of electric current so as to be heated and secured to one surface of a co-extensive strengthening backing film, the other surface of the film being adhered to the carrier so that the strips and films form a series of conducting tapes on the carrier.  A layer of adhesive is applied on the surface of the strips remote from the carrier, which adhesive is such as to enable the tapes to adhere to the car window when the strips are pressed against it with a strength greater than that with which the tapes adhere to the carrier so that, after being applied to the window, the carrier can be peeled off from the tapes.  In applying the demisting device, the strips and films are first formed into the con-ductive tapes which are spacedly secured to the carrier sheet.          An adhesive is then applied onto the surface of the aluminum strips remote from the carrier, which adhesive is such as to enable the tapes to adhere to a window with a strength greater than that with which the tapes adhere to the carrier.  Self-adhesive members of electrically conductive material are then applied to the window and, thereafter, the composite arrange-ment of tapes and carrier is applied to the window with the adhesive surface of the strips foremost so that selected strip portions adhere to the electrically conductive members and the remaining portions adhere to the window.  The sheet material is peeled off to leave the tapes secured to the window and the self-adhesive electrically conductive members are connected to the car battery.

Abstract: CURRENT CONTROL CIRCUIT              ABSTRACT OF THE DISCLOSURE          A current control circuit for a muting circuit including a current mirror circuit formed of first and second transistor devices, one of which being operative to receive a controllable current and the other being operative to conduct a current whose value is determined by and changeable with the controllable current, such other transistor device being adapted to be connected to a load.  A constant current generator generates a substantially constant current and is connected to a current-responsive circuit which, in turn, supplies the controllable current to the first-mentioned transistor device included in the current mirror circuit.  A variable conducting circuit is coupled to the constant current generator for conducting a selectively variable amount of the constant current such that the level of the controllable current which is supplied to the first-mentioned transistor device is established in accordance with the difference between the constant current and the current conducted by the variable conducting circuit.  Thus, the current through the current mirror circuit, and thus the load current, is determined by the conductivity of the variable conducting circuit.

Abstract: ABSTRACT OF THE DISCLOSURE           An ultrasonic pulse echo real time imaging system com-prises a segmented transducer array formed by a plurality of jux-taposed transducer elements.  Successive scans are performed by forming a first predetermined quantity of juxtaposed elements and incrementally shifting said first quantity along said array and subsequently shifting a second quantity of elements along the array, said first and said second quantity being different, for example four and three elements respectively.  If the re-spective quantities are shifted incrementally by one element, the beam axis is stepped by one-half element width only, thereby providing improved image resolution.  The image presentation on a cathode ray tube makes use of the interlacing feature, specif-ically the B-scan presentation line raster responsive to alternate array scans is interlaced.

Abstract: ABSTRACT:                  Remote-focus X-ray tubes, in particular dental X-ray tubes, have the problem that the focus is shifted as a result of which the emission distribution changes. It has now been found that a cause of said shifting is the earth magnetic field and, sometimes, magnetic fields pro-duced by electromagnetic elements of the apparatus. In order to eliminate these magnetic fields the anode tube is surrounded by a soft-magnetic layer which is dimensioned so that it serves at the same time as prefilter for the useful radiation emitted by the target.
