Patent DE-3810734-A1 (DE)
Title: Thread-traversing apparatus
Inventor: SCHMID REINHOLD
IPC: B65H54/28
Filed: 1988-03-30
Abstract: The thread-guide rods (2, 3) driveable in oscillation and in opposition possess at their starts and ends pneumatic constant-pressure cylinders (14 to 17) having a volume variable in time with the movement of the thread-guide rods (2, 3). The constant pressure is kept largely constant by connecting the cylinder spaces (18, 19) or (20, 21) in pairs to pressure-holding devices (30, 31). Arranged at the rod ends are additional devices (22 to 25) for compensating the stress peaks or stress fluctuations occurring on the occasion of the reversal of movement in the thread-guide rods (2, 3).   <IMAGE>

Patent DE-3828041-A1 (DE)
Title: Control method for fault indicators in laundry driers
Inventor: KLUG HANS-JOACHIM DIPL ING
IPC: D06F58/50
Filed: 1988-08-18
Abstract: A fault must be signalled to the user even before the machine is started up and a cancellation of the signal must be linked necessarily to the elimination of the cause of the fault. Known indicator devices signal a fault only during operation. In the control method according to the invention, temperatures or air quantities are determined immediately, before the machine is started up, via thermostats or retaining flaps by means of a time-compressed programme-controlled machine test run. The size of these parameters governs the indication of a fault signal. In the event of a fault and after the defects have been rectified by the customer, the actual elimination of the fault is checked by means of a second test run and, if appropriate, the fault indication is necessarily cancelled. The control method is suitable both for exhaust-air and for condensation driers.

Title: Method and measuring device for determining the diameter of rollers
Inventor: DORNHOEFER REINHARD DR ING

Filed: 1988-09-15
Abstract: To determine the diameter of a roller to be machined on an NC lathe, feelers operating on both sides of the roller are provided which are located at a constant distance from one another which is greater than the diameter of the roller. By common movement of the operating feelers, first one feeler and then the other feeler is brought into contact with the surface of the roller, as a result of which the distances of the two feelers from the roller can be determined, and the diameter can be determined from these distances and the common distance between the feelers.
Patent DE-3834868-A1 (DE)
Title: Overvoltage arrester
Inventor: REITZ ERHARD DIPL ING
IPC: H01T1/12
Filed: 1988-10-13
Abstract: The intention is to make it possible, by simple visual inspection, to ascertain whether or not an overvoltage arrester is still fully operational. The overvoltage arrester is equipped with an indicator which is permanently altered when the arrester responds if future functional impairments of the function can occur through excessive loading of the overvoltage arrester. Dyes or wires which melt at a predetermined current are used as the indicator. The alterations of the indicators can be easily recognised, so that overvoltage arresters which are to be changed can be identified without complicated measuring methods.

Title: Noise and creep redn. underlay for tray tracks - old tyres are converted into plates which reduce maintenance cost and uneven road surfaces
Inventor: SCHLIMME CHRISTIAN A
IPC: E01B9/68
Filed: 1990-04-26
Abstract: Rubber plates mfd. from old rubber tyres can be used as a cheaper alternative to cast polymers in the underlay from tram tracks.

Title: Mechanical press overload protection system
Inventor: HARSCH ERICH
IPC: B30B15/28
Filed: 1990-11-15
Abstract: The mechanical press head has its crankshaft connected to several pistons (5), which operate in hydraulic cylinders (7). An upward force (Fv) can be exerted on each piston by the pressure of hydraulic fluid from a pump (10), driven by a motor (M). The space in each cylinder below the piston is connected to a pressure overload valve (15) which has a stepped piston (16). The smaller piston dia. (17) is acted on by the pressure in the hydraulic cylinder (1,2), with the larger piston dia. (18) connected directly to the pump. On an unequal load on the press ram, the pressure in the corresp. cylinder is increased and acts on the smaller dia. The valve is open, when the pressure on the underside of the piston exceeds the pressure on its upper side by a given ratio.
