Title: Test device on ring spinning or ring twisting machines for a visual test of the eccentricity between a spindle and an associated ring
Inventor: HOESEL MARTIN
IPC: D01H7/52
Filed: 1985-12-07
Abstract: The invention relates to a test device on ring spinning or ring twisting machines for a visual test of the eccentricity between a spindle and an associated ring, in which the viewing direction along the spindle axis is directed towards the spindle tip, and there is arranged on the spindle a spindle attachment with an outer edge concentric relative to the spindle, on the ring a ring attachment with an inner edge concentric relative to the ring and between the spindle and the ring, under the outer edge of the spindle attachment and the inner edge of the ring attachment in the viewing direction, a bright field generated by a lighting device. The object on which it is based is to eliminate extra outlay incurred by additional measurements of the eccentricity and their evaluation or by the centring of spindles within the permissible eccentricity. The object is achieved in that the diameter (10) of the outer edge (7) of the spindle attachment (6) is larger by double the amount of the permissible eccentricity than the diameter (11) of the inner edge (9) of the ring attachment (8) - Fig. 1 -. The invention achieves the technical effect that the permissible eccentricity is taken into account in the test or in the centring between spindle and ring. <IMAGE>

Title: Control device for combining a conventional heating system with a heat pump system
Inventor: GOERICKE PETER DIPL ING
IPC: F24D3/18
Filed: 1985-12-19
Abstract: A control device for combining a conventional heating system which exhibits an electronic climatically controlled control device, with a heat pump system during the reconstruction of the conventional heating system into a bivalent heating system, the conventional heating system exhibiting a heating boiler with burner monitored by a heating boiler thermostat, a mixing valve with mixing valve actuating motor and a heat distribution system connected to the mixing valve. The control device controls, in dependence on the outside air temperature, in accordance with a nominal value set as determined by a heating curve, the heating water advance temperature of the heating system. The mixing valve and/or the mixing valve actuating motor exhibits limit switches for the shutting and for the opening of the mixing valve. At the limit switch for the shutting and at the limit switch for the opening, an electronic transmitting/receiving device is connected which conducts a high-frequency low-voltage signal via the limit switches. When the burner is switched off by the mixing valve or the mixing valve actuating monitor, the electronic transmitting/receiving device activates the heat pump system via a delay element in correspondence with the opening of the mixing valve. The system is deactivated when the mixing valve is closed.

Patent DE-3617036-A1 (DE)
Title: Pressure-swing adsorption process
Inventor: LEIS JOHANN DIPL ING
IPC: C01B32/40
Filed: 1986-05-21
Abstract: A pressure-swing adsorption process is proposed for dividing a gas mixture containing at least two components differing in the strength of their adsorbability. In an adsorption phase, the gas mixture is conducted through an adsorber, a more strongly adsorbable component being bound to an adsorbent. After the adsorption phase, more weakly adsorbable components remaining in the adsorber are flushed out by introducing a gas which essentially comprises the more strongly adsorbable component. The more strongly adsorbable component is then isolated by pressure reduction in the adsorber to a subatmospheric pressure. When a gas mixture is divided having a content of 40 to 75% of the more strongly adsorbable component, after the evacuation of the adsorber to a pressure between 0.03 and 0.3 bar, a first pressure build-up phase is carried out, during which, unadsorbed gas which leaves an adsorber during the adsorption phase is introduced into the adsorber in counter-current to the direction of adsorption until an intermediate pressure in the range from 0.1 to 1 bar has built up. Further pressure build-up is then carried out with expansion gas from another adsorber and/or with the gas mixture to be divided.

Patent DE-3627848-A1 (DE)
Title: Lightweight aggregates for mortar mixtures and concrete mixtures with reduced water absorption, cement-bound moulded articles produced with the use of said aggregates and process for the production of the aggregates and the moulded articles
Inventor: WUESTEFELD ALOYS DR
IPC: C04B20/10
Filed: 1986-08-16
Abstract: According to the present invention, the reduction of the wettability of porous, lightweight aggregates in mortar mixtures reduces the water absorption of the mortar and in the process the amount m of the aggregate wetted decreases according to the formula (b . F-m)/b . F = 1 + cos  alpha  -0.166  rho , designated the volume relation of the aggregate. b signifies the particle size and F the surface area of the aggregate,  alpha  is the wetting angle and  rho  is the specific weight of the aggregate. From this there emerge consequences for the magnitude of the water/cement ratio which is composed of the following factors:     1. Bulk density a of the aggregate   2. Volume ratio cement to aggregate Vz/Vp 3. The volume ratio, determined by the wettability, of the aggregate, which according to the invention is determined by the formula 1 + cos  alpha  -0.166  rho .   The water/cement ratio is in this case  1/a . (1 + cos  alpha  -0.166  rho ) . Vz/Vp = f. If the amount m wetted decreases and the wetting angle  alpha becomes smaller, the water/cement ratio is higher. On the other hand, the water/cement ratio assumes a smaller value with increase of the wetting angle to 90 DEG , that is to say until complete wettability, because, with the same water addition, a further portion of the water is absorbed by the porous aggregate. The porous aggregates with incomplete wettability, for example perlite, are coated with metal oxides. The process for coating is [lacuna] in ... Original abstract incomplete.

Title: Air cooling for a vehicle brake
Inventor: HUETTENBERGER MICHAEL DIPL ING
IPC: F16D65/847

Abstract: The invention relates to air cooling for a vehicle brake with a guide duct, through which an inlet air flow entering an inlet cross-section of the guide duct can be fed to an assigned brake device and a heat exchanger with forced air ventilation. In order to reduce the dependence of the vehicle brake air cooling on the air slip stream, it is proposed that the heat exchanger be arranged in the guide duct in such a way that the cool air fed to the brake device is essentially constituted by the outlet air flow of the heat exchanger.
