Granted: 1985-09-05
Abstract: A hitch system includes a yoke pivotally supported by the ends of a rockshaft extending from the sides of the tractor housing. The yoke includes left and right side panels and a two-piece bottom. A drawbar is pivotally coupled to the yoke between the two bottom pieces. Left and right draft links have fore ends pivotally coupled to the yoke and are sway limited in the down position by sway links connecting each draft link with an inboard portion of the yoke. The draft links are sway limited in the raised position by sway surfaces on the sides of the yoke. Lift arms are splined to the rockshaft ends and are pivoted by a pair of lift cylinders coupled between the lift arms and the housing. A pair of lift links connect the lift arms to the draft links. A yoke positioning and draft sensing link includes a fore end connected to a bottom side of the housing and an aft end connected to the yoke. Draft loads from the draft links and from the drawbar are communicated via the yoke to a draft sensor in the yoke positioning and draft sensing link.

Title: Method and device for the colorimetric analysis of a printed colour test scale
Inventor: OTT HANS
IPC: B41F33/00
Filed: 1982-03-30
Granted: 1985-10-03
Abstract: On a measuring table (1), a bridge (2) extends over a printed sheet (5) to be measured. A measuring carriage (3) carrying a three color-simultaneous measuring head is arranged on the bridge (2) for linear movement in a back-and-forth manner along a desired path on the printed sheet. For control of the movement of the measuring head during measuring runs and for the evaluation of the measured data, a computer (7) with an integrated image display terminal and a processor system (6) controlled by the computer, is provided with the necessary interfaces. The analysis of a color measuring strip (MS) located along the desired path on the printed sheet is effected in two phases. In a first, so-called recognition run the measuring strip is scanned stepwise with high resolution in all three color channels, for the purpose of an analysis of its configuration. By means of flat locations in the density variations, effective positions (e.g., the centers) in the measuring fields are determined as possible measuring positions for subsequent measuring runs. During the measuring runs the measuring strip is measured only at the measuring positions determined during the recognition and the measured data obtained in this manner are transmitted for processing and/or display to the computer (7). By the division of the measurements into a recognition and a measuring run, coupled with the determination of measuring positions by means of flat locations in the density variations, a practically completely automatic evaluation of the color measuring strips independently of their configuration and without the need of prior knowledge of the strips by the apparatus, is rendered possible.

Title: Electrode for sensing the voltage of a source having a plane contact region
Inventor: TROESCH JACQUES J
IPC: G01R19/00
Filed: 1982-02-04
Granted: 1988-07-28
Abstract: A circuit for measuring electric signals of high resistance, for example for measuring high-tension or capacitive voltage sources, is provided by connecting the source (1) to be measured to an operational amplifier (3) so that it operates as an inverter (Z<ue>u, Z<uk>u). The driving point impedance may be the high internal impedance of the source. The output of the operational amplifier (3) will be so arranged as to be on the second end connection of the source to be measured through a regulator (7) where the sampled voltage (U<ux>u) appears as an adjusting variable. The leakage current will be compensated by means creating a compensating current (I<uk>u). The provision of a capacitance as an driving point impedance (Z<ue>u) and a reverse feedback impedance (Z<uk>u) together with the regulator (7) allows in particular the capacitive measuring of a source (1) of DC voltage. The amplification of the open circuit must be taken into consideration (i. e.: very high impedance conditions).

Title: Heat exchanger plate
Inventor: BERGQVIST JAN-OVE
IPC: F28D/
Filed: 1984-12-05
Granted: 1987-08-27
Abstract: A heat exchanger plate has a primary heat exchange part (1b), two secondary heat exchange parts (2b, 3b) placed on each side of this one and four holes or ports (4b, 5b, 6b, 7b). Two of the ports are located at one of the secondary heat exchange parts in the same distance from but on each side of a centre line (M) of the plate. The two other ports are in a corresponding way located at the other secondary heat exchange part. The plate has in all heat exchange parts (1b, 2b, 3b) ridges and valleys embossed into it, which are so placed that when two plates are put against each other - one of them turned 180<o> relative to the other one - ridges in one plate intersectingly rest against ridges in the other plate. At least the ridges and the valleys in the secondary heat exchange parts (2b, 3b) are so embossed that they have a volume of essentially the same size on respective sides of the plate. In a plate of this kind each of the two secondary heat exchange parts is provided with ridges and valleys forming an angle with the centre line (M) of the plate. This angle (or these angles) differs from the angle (the angles) which the ridges and the valleys in the primary heat exchange part (1b) of the plate form with the centre line (M). Furthermore, the ridges and valleys of the plate form such angles with the centre line (M) that in a plate interspace they bring about less flow resistance in the areas of the secondary heat exchange parts (2b, 3b) of the plates - on both sides of the centre line (M) - than in the area of the primary heat exchange part (M) of the plates.

Abstract: Process and apparatus for preventing defects in the symmetry of rolled H-beams or I-beams, i.e., a faulty position of their webs (4) in relation to their flanges (5), by correcting such defects in situ. The differential between the torques applied to the upper and lower rolls (1,2) of the rolling stand is determined and compared to a predetermined threshhold value ( delta ). Any excess of the measured value over the threshhold value is eliminated by correction of the elevation of the inlet table of the rolling stand so as to reduce the measured value to below the threshhold value.

Title: Line mounted apparatus for measuring line potential
Inventor: MONTGOMERY JOHN RICHARD
IPC: G01R19/155
Filed: 1985-06-03
Granted: 1989-10-26
Abstract: A self contained hot stick mounted radio transmitting module may be permanently mounted on or temporarily pushed against the power conductor of electrical transmission line (3). The module is capable of measuring the potential difference between the conductor and ground. The module digitizes and transmits the value of the potential difference to a ground receiver. The module is donut shaped and opens like a pair of jaws. The contact with the power line is accomplished via a resilient conductive elastomer that covers the surfaces in contact with the power conductor. The potential difference between ground and the power conductor is measured with an operational amplifier (19) in an integrating configuration to convert the leakage current from the module to ground into a proportional voltage from a low impedance source. The integrator outputs a voltage proportional to the current flowing into the equivalent capacitance formed by the outer surface of the module and ground. The current is generated by the voltage difference between the power conductor and ground. The power conductor (3) is engaged by a pair of jaws inserts comprising two concentric conducting rings separated by a thin insulating layer forming a large capacitor. The electronic components within the unit are protected by a signal conditioning network to preclude destruction of components in the event of lightning strikes or other overvoltage conditions.

Abstract: A blood pressure cuff is applied about a subject's artery, and inflated above the systolic level thus fully occluding the artery for a full heart cycle. The cuff pressure is thereafter reduced to permit an increasing flow through the progressively less occluded artery, and a measure of the peak amplitudes of the successively encountered blood flow (oscillatory complex) pulses stores in memory. Also retained is the cuff pressure obtaining for each stored complex peak. In accordance with varying aspects of the present invention, the stored complex peak-representing data ensemble is corrected for aberrations; and improved data processing operates on the stored (and advantageously corrected) pulse peak data and the responding cuff pressure information to determine the subject's mean arterial blood pressure.
