Patent DE-3137484-A1 (DE)
Title: Measuring device on agricultural machines and appliances
Inventor: KIRCHBERGER FRANZ
IPC: A01C15/00
Filed: 1981-09-21
Abstract: A measuring device on agricultural machines and appliances for the continuous recording and indication of the content of an accompanying supply container for liquid, powdery or granular cultivating material, such as seed corn, fertiliser, herbicides or pesticides, to be discharged onto the useful agricultural area. The adjusters provided on the machines for the spreading or spraying of such agents are set, before the start of field work, by means of tables or on the basis of empirical values, in order to ensure an optimum crop yield. However, the desired values are not achieved during field work, because a multiplicity of influencing factors falsify the result, such as, for example, the slip of the driving wheels, travelling up a slope, vibrations acting on the metering mechanism, varying slidability of the corn grains or of the fertiliser and, as a result, so-called bridge formation, a change in viscosity of the spraying agent, etc. The invention provides the farmer with an electrical measuring device, by means of which the content of the supply container can be read off continuously in kg or litres, during travel, in the field of vision of the traction-engine or tractor driver. For this purpose, the supply container is suspended freely on a supporting frame of the machine and is guided vertically within fixed limits virtually without friction and in an elastically resilient manner. By means of a holding member movable on all sides, the container is fastened to a flexural or torsional bearer which transmits the effect of the essentially vertical forces constituting the weight of the agent in the container to an electrical pressure-measuring device, preferably a measuring bridge with strain gauges. <IMAGE>

Title: Cutting machine
Inventor: RIETZKE MANFRED
IPC: B26D7/01
Filed: 1981-10-28
Abstract: In a cutting machine, a stop plate for the material to be cut is adjustable, plane-parallel to the plane of a disc cutter (3), on opposite sides via guide webs (11) extending obliquely with respect to the adjusting direction and counter-webs (12) for setting the size of the cut. The counter-webs (12) are situated on a slide (4) which is in driving connection, via a pin (5), with a groove (7), extending in the form of a spiral, in a setting knob mounted rotatably on the housing. To be able to detach the stop plate by its guides (11) from the counter-webs (12) without the need for special assembly work, the groove (7) has a radially extending portion (6). This radial portion (6) is situated at the inner end of the groove (7) and points, when the stop plate is pushed out towards the cutter (3), in the adjusting direction of the slide (4). In this position, the slide (4) can be manually displaced so that the pin (5) moves into the portion (6). As a result, the counter-webs (12) are detached from the guide webs (11), so that the stop plate can be removed freely at the front. <IMAGE>

Patent DE-3216580-A1 (DE)
Title: Load-holding and load-lowering brake valve
Inventor: ANDERSSON LARS YNGVE
IPC: B66C13/18
Filed: 1982-05-04
Abstract: A load-holding and load-lowering brake valve for linear and non-linear hydraulic motors. The valve (1) consists of a counterholding valve (13), which is connected in parallel with a first non-return valve (15) in the line to the lifting side of the motor, and a restrictor valve (12) which is connected in parallel with a second non-return valve (14) in the line to the lowering side (4) of the motor. The first non-return valve (15) directs hydraulic fluid to the motor past the counterholding valve and forces fluid from the motor to pass the counterholding valve when the latter is open. The second non-return valve (14) allows fluid from the lowering side of the motor to pass it and forces all the fluid to the lowering side of the motor to pass the restrictor valve. During increased load, i.e. during increasing pressure in the line (9) from the lifting side of the motor, the restriction of the restrictor valve increases so that the lowering speed of the motor drops. The counterholding valve is opened by the pressure in the line (10) between the restrictor valve (12) and the lowering side (4) of the motor reaching a certain value. <IMAGE>

Title: E-field wire attachment
Inventor: WEBER SIEGFRIED DIPL ING
IPC: G08B13/12
Filed: 1982-05-15
Abstract: The E-field wires (1) of an E-field line sensor system of a perimeter security system must maintain their position as accurately as possible with respect to their function, for which reason position changes as a result of the influence of temperature are prevented in that the E-field wires (1) are continuously subjected to a constant, relatively high tensile force. It is thus necessary to mount the E-field wire (1) securely on the insulator (3). This is done according to the invention in that, after looping around the insulator (3), the free end of the E-field wire (1) loops around the E-field wire (1), in that the free end loops around the insulator (3) a second time (in the opposite direction) and is finally wound around the E-field wire (1) with a number of turns. <IMAGE>
