Title: Stopping control for pressure-operated drive - has fluid flow to drive progressively decreased as motion of driven object continues
Inventor: TAAKE MANFRED
IPC: F15B11/048
Filed: 1980-07-24
Abstract: The control has a valve restricting the flow of fluid to the drive. The drive moves a body linearly. The valve is controlled by a setting device (11,14,15) which is operated in accordance with the movement of the body such that the setting device converts the continued motion of the body along its path into a continual restriction of fluid flow to the drive by the valve (5). The setting device has a control member (11) moved by the body and coupled (14) to the moving part of the valve. The coupler (14) is switched on when the body reaches the starting point of the selected section of its path of travel. The advantage lies in bringing the body reliably and safely to a stop without oscillations.

Title: Mains disconnection device
Inventor: SICHINGER JOSEF
IPC: H04M11/00
Filed: 1981-03-27
Abstract: In rooms in which telephone systems are installed, further electrical devices are often operated which either severely impair the interference-free making of a telephone call due to particularly severe noise formation, or which distract the attention of the person making the call. The invention is designed to ensure that devices of this type are automatically de-activated when a telephone call is received. For this purpose, a mains disconnection device is provided according to the invention which is galvanically, inductively or capacitively connected to the telecommunication network in such a way that an acoustic or other electrical device which is in operation at the time is disconnected from the mains or its loudspeaker is disconnected from the device by a call signal via a switching device. Despite the presence of further devices in the same room in which the call is to take place, it is now ensured that, while the call is in progress, any disturbance caused by these devices to the person making the call is eliminated. The re-activation of the device concerned can be performed automatically or by means of a specific re-activation button. <IMAGE>

Title: Process for the preparation of a composition for filling the exits and for reconstructing stone buildings, in particular antiquated buildings
Inventor: DOMASLOWSKI WIESLAW PROF DR
IPC: C04B26/14
Filed: 1981-07-15
Abstract: The invention relates to a process for the preparation of a composition for filling the exits and for reconstructing stone buildings, in particular antiquated buildings, using a liquid epoxy resin containing, as curing agent, triethyltetramine or other curing agents which act at room temperature. From 5 to 50 parts of an aggregate matched in granulation and colour to the stone to be reconstructed are mixed with 1 part of an epoxy resin having an EW of from 0.48 to 0.50 - containing triethyltetramine as curing agent - after which, in order to screen the composition from the action of carbonic acid, the free spaces in the composition are filled with petroleum spirit. The composition is compacted by tamping or pressing. The curing time of the composition is adjusted by means of the solvent added to the resin before mixing with the curing agent, ethyl alcohol in an amount of from 5 to 20% accelerating the curing process at a temperature of below 18 DEG C and addition of toluene delaying the curing process at a temperature above 18 DEG C. After the resin has been mixed with the aggregate, the plasticity of the composition is increased by addition of a 10 to 15% strength alcohol solution of polyvinyl acetate. After the shaped element has been cured and dried, the outer layer of the composition is removed and then placed in a water envelope, preferably of hot water, until dry.
Patent DE-3134169-A1 (DE)
Title: Intake arrangement in compressors
Inventor: KALTENTHALER WOLFGANG ING GRAD
IPC: F04B39/16
Filed: 1981-08-28
Abstract: The oil which penetrates in small amounts into the compression cavity past the piston of a compressor enters the circuit of the installation connected to the compressor. Instead of using an oil separator, the invention is based on the concept of separating the oil in the intake chamber of the compressor. According to the invention, the intake chamber is given such a shape that high air velocities cause centrifugal forces which fling the oil against the walls of the intake chamber from where it flows back into the crank chamber. In refrigeration systems it is possible, by virtue of the same measure, for any liquid refrigerants which may have penetrated to evaporate before these likewise penetrate into the compression cavity past the piston.

Title: Press with built-on strapping channel
Inventor: NOLTE HEINZ JOSEF
IPC: B65B27/12
Filed: 1982-03-06
Abstract: In a strapping channel built into a press, the disadvantage is that the part of the strapping channel built into the press ram is no longer in alignment with the remaining fixed part of the strapping channel when the end position of the press ram is slightly advanced, which can be brought about by leakage losses or elasticity. According to the invention, differences are compensated by additionally incorporating a compensating part of the strapping channel between the fixed part of the strapping channel and the press ram. This compensating part is fastened to the fixed part of the strapping channel to be slightly rotatable and its end lying on the press ram is carried along by a stop located on the press ram, in each case shortly before the end position of the press ram during the pressing stroke of the latter, thereby bringing about alignment of the parts of the strapping channel.
