Title: Device for determining the weight of loads coupled to a tractor
Inventor: HESSE HORST DIPL ING DR
IPC: A01B59/06
Filed: 1993-08-21
Abstract: A device (10) for determining the weight of loads coupled to a tractor (11) is proposed, which device is coupled to the tractor in a vertically adjustable way by means of a hydraulically actuable linkage of an electrohydraulic control device (14) for a lifting mechanism, it being possible to derive the weight by means of the signals of a load-dependent pressure sensor. In order to minimise the influence of longitudinal inclinations when determining the weight of coupled loads, an inclination sensor (29) is arranged on the tractor (11), as a function of the signals of which inclination sensor (29) the pressure value determined in each case with longitudinal inclination in the electronic control device (26) is converted to a pressure value which is appropriate for the stationary tractor, which values permit more accurate comparable weighing. <IMAGE>

Filed: 1994-02-03
Abstract: Process to determine the content X1 in the para form of gaseous hydrogen, where: (a) the temp. T1 and pressure P1 of the hydrogen gas flow is measured before it enters at least one para-ortho conversion zone under adiabatic conditions; (b) the gaseous hydrogen flows into a para-ortho catalytic conversion zone until equilibrium is established; (c) the temp. T2 and pressure P2 of the hydrogen gas flow is measured after it leaves the last conversion zone; (d) using the equilibrium equations h1 (X1, T1, P1) = h2 (X2, T2, P2) and X2 = Xg (T2), (in which h1 is the enthalpy of the hydrogen gas at the inlet and h2 at the outlet), the content X1 in the para form is determined at the instant before it enters the conversion zone.  Also claimed is the device to carry out the above process where the hydrogen gas flow is brought in a feed pipe to a para-ortho catalytic conversion zone (4) which is thermally isolated from the surroundings and means of measuring the temps.  T1 and T2 are located at the inlet and outlet of this zone. The gas flow leaves the conversion zone through an outlet pipe.

Title: Auxiliary appts. built into TV receiver
Inventor: MARCHNER OTTO
IPC: H04N5/44
Filed: 1994-03-10
Abstract: The appts. begins to record on video the programme currently being transmitted and appearing on the TV screen when a switch is operated. If the viewer, having missed a section of the programme, operates a second switch, the appts. displays the video recording, suitably shifted in time, in place of the actual transmission, while continuing to record the programme as it is transmitted. The viewer can operate a third switch to reduce gradually the time difference between the video playback and the actual transmission, until the time shift is eliminated or the programme ends. This is achieved by increasing the speed of the video playback. A visual display indicates in minutes and seconds the time difference between the actual transmission and the video playback. Realisation can be by a double deck recorder, a two head for two tapes or a PC using a so-called high value video card and digitising the images for storing on a main memory.

Title: Automatic control of melting between thermoplastic products
Inventor: KUMAGAI MASARU
IPC: B29C65/34
Filed: 1994-10-04
Abstract: In a method of automatically controlling the fusion process of thermoplastic resin articles a current is fed to a resistor for fusing together the resin surfaces facing one another. Electrical characteristics of the resistor is calculated upon increase of the power to a given level, also calculating specific heat of the resin through ON-OFF control of the resistor. The power is then raised through stages based on the characteristics and the specific heat, to determine variation coefficients of the characteristics and specific heat, at each stage and through further ON-OFF control. The power is stopped as the variation coefficient becomes smaller than a given value, with the ON-OFF control continued until the specific heat becomes equal to or lower than a preset value to cease the power supply. The method may be applied to pipe joints (Figures 2 - 4) or fusible tapes (Figures 5 and 6). <IMAGE>
