Title: Draft control for an implement linkage
Inventor: BENEDEK VASILE
IPC: A01B63/112
Filed: 1983-10-25
Granted: 1987-02-19
Abstract: Disclosed herein is a support for supporting the load sensing bar of a draft control system. The support includes an L-shaped bracket which is adapted to have one leg attached to a vehicle and the other extending outwardly therefrom. The attached leg has a through opening with a spherical bearing therein through which the load sensing bar passes. A stop is carried on the other end of the outwardly projecting leg to limit bending of the bar. A clip is also carried by the outwardly extending leg and extends to a position where it will prevent the bar from sliding out of the bearing in the attached leg in the event the bar breaks.

Title: Video recorder

Granted: 1987-01-15
Abstract: In present video equipment for recording a colour video signal on a magnetic tape the what is commonly referred to as the "colour under" transmission method is used. Therein, starting from the composite colour video signal, luminance and chrominance signals are separated from each other and both bandwidths are considerably limited. The frequency band of the luminance signal is converted to a first transmission band by means of frequency modulation. The frequency band of the chrominance signal is converted by means of amplitude modulation to a second transmission band located below the first band and which does not overlap this first transmission band. 
<??>In order to counteract considerable bandwidth limitation of these two signals and to reduce the influence of transmission noise on the chrominance signal, a transmission method is now proposed which will be denoted as the "color shift" method. Therein the composite colour video signal which is formed by a sequence of analogue line signals is sampled, as a result of which each analogue line signal is converted into a time-discrete line signal formed by a plurality of line signal samples occurring at a rate fs, each sample being formed from the sum of a luminance and a chrominance signal sample. Thereafter, these time-discrete line signals are submitted to a scrambling operation in which in accordance with a predetermined pattern a number of line signal samples is each time selected from the line signal samples of a group of time-discrete line signals for assembling time-discrete auxiliary line signals. This selection is effected such that of all those line signal samples which together represent a given time-discrete auxiliary line signal the associated chrominance signal samples all have the same polarities. As a result thereof the chrominance signal is converted without bandwidth limitation to a lower frequency band, while it continues to be located within the frequency band occupied by the luminance signal. This new composite colour video signal can now, after having been converted into an analogue signal, be transposed in its totality to a suitable transmission band by means of frequency modulation.

Abstract: PCT No. PCT/AT84/00010 Sec. 371 Date Oct. 12, 1984 Sec. 102(e) Date Oct. 12, 1984 PCT Filed Feb. 27, 1984 PCT Pub. No. WO84/03571 PCT Pub. Date Sep. 13, 1984.The invention relates to an optically structured filter with predominantly smooth or planar surfaces. Such filters are used as primary masks for the photolithographically manufacturing microelectronic elements, having with at least one pattern with a different transmission in relation to an electromagnetic radiation to be filtered. A filter layer consists of a material of locally homogeneous transmission into which ions, preferably metal ions with an energy of more than 1 keV, are implanted for producing the pattern(s) with the different transmission. This makes it possible to produce filters having patterns with regions of different transmissions for various wave lengths. Suitable materials to be used for the filter layer are materials such as inorganic and organic polymers and glasses as well as mono- and polycrystalline oxides or nitrides. The ion implantation itself is carried out by means of process steps known per se.

Abstract: An internal combustion steam engine is operated with an alcohol-water fuel mixture vaporized prior to combustion by heated engine coolant that flows through a first heat exchanger (18). The first heat exchanger or vapor generator (18) uses the waste heat from the engine coolant to heat and vaporize the alcoholwater mixture. A second heat exchanger (60) using exhaust gases heats the combustion air before passage through the intake manifold (46). Complete vaporization of the alcohol fuel is accomplished to overcome the lower caloric power potential of alcohol as compared to gasoline and to insure complete and regular combustion.

Title: Deflector for a lamelliform freely floating viscous coating material
Inventor: SPENGLER WALTER
IPC: B05C5/00
Filed: 1986-02-22
Granted: 1988-07-14
Abstract: A deflecting device includes a deflecting electrode (13), which is disposed at a spacing below a lip nozzle (11.1), from which the viscous coating material (10.2, 10.1) flowing freely in the form of a sheet is emerging, and which extends over the entire width of the coating material sheet. This deflecting electrode includes an electrode arrangement (31), the exposure region of which facing the sheet surface is subdivided into a number of electrode elements (33) which taper outwardly to a point. When placed under a voltage, the electrode arrangement (31) provides an ion stream directed towards the surface of the coating material sheet. The impact of this ion stream on the surface of the coating material sheet (10.2) imparts to the latter a change in direction ( alpha ) towards the deflecting electrode (13), so that a flat substrate (5.1) running horizontally towards the deflected coating material sheet (10.1) impinges on the sheet (10.1) at an acute angle ( beta ). The impact of the substrate (5.1) on the sheet (10.1) at an acute angle causes a smooth, undulation-free application of the coating material to the substrate surface.

Abstract: Sensor systems and methods for detecting the position and/or movement of an object in multiple degrees of freedom. The sensor system of the present invention comprises at least one field-effect transistor (FET), the geometrical configuration of the FET being selected so as to provide the desired sensitivity. The FET is preferably provided with a conductive gate adjacent to but insulated from the channel region of the FET. An object whose position and/or movement is to be detected is prepared such that an electric field emanates from the object. The FET is brought into the vicinity of the object, and the electric field emanating from the object interacts with the gate and/or channel region of the FET so as to modify the magnitude of the electrical current flowing through the channel region. The current through the channel region is detected and is used to obtain information about the position and movement of the object relative to the channel region of the FET. By positioning a plurality of substantially coplanar FETs in the vicinity of the object, the position and/or movement of the object in any desired number of degrees of freedom can be detected and monitored.

Abstract: The new invention concerns the regulation of air volume in a conveying system comprising an air collecting line (37) in which the air volume and the corresponding air velocity, respectively, is regulated in the individual conveying pipelines (30-36) by a lifting body (4) resembling an airfoil. The latter works like a throttle flap and moves from an incidence angle ( alpha ,  beta ) of at least 10 degrees in the completely open position to 90 degrees in the closed position as a result of the lifting moments acting on it. The lifting body (4) itself regulates the air volume by means of blocking the air line cross section to a greater or lesser extent, wherein a balance is adjusted in every case between the air forces and lifting moments, respectively, which act at the lifting body (4) so as to be directed in a closing position and a counterweight (5) or countertorque, respectively, acting at the lifting body (4) in the opening direction. A responsiveness which has not been previously achieved can accordingly be achieved from every position and an optimal regulating characteristic, e.g. at an approximately constant air velocity, can accordingly be achieved independently of the air resistance occurring prior to the regulating unit.
