Patent DE-3107822-A1 (DE)
Title: Valve for tubeless tyres
Inventor: OPEL PAUL DIPL PHYS
IPC: B60C29/02
Filed: 1981-02-25
Abstract: The invention relates to a valve for tubeless tyres, consisting of a metallic valve body with valve insert and a rubber body which can be inserted into a valve hole of a rim. By means of the invention the object is achieved of providing a new valve design by means of which it is possible to remove and install a valve from the outside, that is to say not from the tyre side and thus without removing the tyre. The valve is accordingly designed as follows:   a) the valve body (1) has on the end facing the rim a threaded component (5) and a shoulder (9) of a stop on the rubber body (2), b) inserted in the rubber body (2) is a metal sleeve (6) with internal thread, c) the metal sleeve is provided with at least three slots (7) which start from the end facing the rim (3), and d) the metal sleeve (6) has a conical tapering (8) on the inside, in the region of the slots (7), towards the rim side. The advantage achieved with the invention consists in a substantial simplification of mounting, that is to say in the case of a defect in the valve it can be replaced without the tyre having to be removed, which is otherwise necessary. <IMAGE>

Patent DE-3229160-A1 (DE)
Title: Process for the operation of an air/water heat pump
Inventor: KUTSCHERA KARLHEINZ DR RER NAT
IPC: F25D21/00
Filed: 1982-08-04
Abstract: In the air temperature region between +10 DEG C and -5 DEG C, the evaporator of air/water heat pumps ices up at high air humidity. When evaporator icing occurs, the time has come where a defrosting process has to be initiated by reversal of the refrigerant circuit. The problem here is to detect icing of the evaporator without considerable outlay. According to the invention, the inlet air temperature ( theta LE) at the evaporator is measured and is compared with a temperature limit value ( theta LEG). Defrosting occurs when the evaporation pressure (pV) of the refrigerant falls below a first, higher defrosting limit pressure (pV1) and simultaneously the inlet air temperature ( theta LE) lies above the temperature limit value ( theta LEG), or when the evaporation pressure (pV) falls below a second, lower defrosting limit pressure (pV2) and simultaneously the inlet air temperature ( theta LE) reaches or falls below the temperature limit value ( theta LEG). <IMAGE>

Title: Apparatus for testing the rheological behaviour of elastoviscous or viscoelastic materials at variable and/or constant temperatures
Inventor: ARAND WOLFGANG PROF DR ING
IPC: G01N3/02
Filed: 1982-11-04
Abstract: The invention relates to a universal testing machine for performing compressive, tensile, relaxation, heating and cooling tests on elastoviscous or viscoelastic materials at variable and/or constant temperatures, with which the sample body lengths under temperature and/or load changes are kept constant, or can be arbitrarily varied, by means of desired/actual comparisons with the aid of a temperature-determined or temperature-independent measurement apparatus and a stepping motor with an accessory gearbox. The detection of very small undesired thermally or loadwise effected length changes of the sample bodies by means of temperature-determined or temperature-independent and unloaded measuring devices on a measurement basis and path transducers releases control pulses for a stepping motor, which reproduces the original length of the sample body or produces desired length changes in dependence on the temperature and/or the time.
