Patent DE-3236577-A1 (DE)
Title: Accumulation roller chain
Inventor: BURKHARDT VOLKER ING GRAD
IPC: B65G17/24
Filed: 1982-10-02
Abstract: Accumulation roller chain for the conveyance of piece goods, with a multiplicity of guide rollers, every two of which are arranged rotatably on a pin at a distance from one another. Running rollers arranged one behind the other are in each case interconnected by means of plates which are arranged laterally on the pins and between the two running rollers of a pin, and thus form an endless chain. Conveying rollers, which are likewise arranged on pins with running rollers, are in each case arranged between two running rollers lying one behind the other and between mutually opposing plates. The conveying rollers have larger diameters than the pins or spacing sleeves pushed over the pins, so that two conveying rollers lying one behind the other together with the pins or spacing sleeves lying in between in each case form indent-like depressions. These indent-like depressions are filled in with bridge-forming filling pieces. The latter are fixed to the respective pins or spacing sleeves. <IMAGE>

Title: Crankcase for reciprocating piston engines
Inventor: HERMANN JOACHIM
IPC: F02F7/00
Filed: 1983-02-18
Abstract: A crankcase (4) for multi-cylinder reciprocating piston internal combustion engines has walls (6) of relatively small thickness arranged transversely to the engine's longitudinal axis (5), in each of which a split bearing (7) is arranged. In order to avoid separately attached ribs whilst nevertheless obtaining sufficient reinforcement, each wall (6) has areas (8 or 8', 9 and 10 or 10') arranged offset in relation to one another in the direction of the engine's longitudinal axis (5), which are connected to one another by webs (11, 11'). In proximity to that bearing part (12) fixed to the wall, angular chambers (13, 14) are formed, in which helical vents (15) with through-holes (16) are arranged. <IMAGE>
Patent DE-3309335-A1 (DE)
Title: Device for light-weight transport system
Inventor: LIESENFELD WERNER
IPC: B61L23/00
Filed: 1983-03-16
Abstract: Rail-bound vehicles for transporting small containers in offices or the like are to observe a mutual safety distance of approximately 20 cm; at the same time, there should be no adverse effects due to a vehicle which is coming in the opposite direction on an adjacent rail. According to Fig. 2, in each case an electromagnetic coil whose longitudinal axes are inclined downwards from the centre of the vehicle by approximately 60 DEG  is located behind the buffers. If the coil, which is the rear one in the direction of travel, is operated for example with an alternating voltage of 200 V and 9.6 kHz, it emits an electromagnetic field which extends to the rear considerably further than to the front and to the side. The receiving coil, located at the front, of a subsequent vehicle receives the radiation well even at a distance of approximately 20 cm, whilst the receiving coil of a vehicle coming in the opposite direction is not influenced due to the inclination of the coil and the weaker lateral field. <IMAGE>

Title: Device for mechanically prestressing a screw connection
Inventor: SCHWEICKERT HERMANN DR ING
IPC: F16B35/04
Filed: 1983-06-14
Abstract: By means of the device (see Figure), it is intended to be possible to prestress screw connections mechanically such that no torsional torque whatsoever is applied to the screw shank. Result: pure tensile stress, no computational safety margin required, consequently smaller screw dimensioning with more economical construction capabilities. Advantages with respect to previously normal prestressing methods (hydraulic, thermal):     simple and quick in use,   none of the auxiliary devices required there are necessary, bolt extension and hence the prestressing force can be measured easily without aids.   Use: the invention is used anywhere where screw connections are dynamically stressed and prestressing is consequently necessary. <IMAGE>

Patent DE-3323241-A1 (DE)
Title: Oxygen probe having ceramic-protected gas electrode
Inventor: KOERTVELYESSY LASZLO DIPL PHYS
IPC: G01N27/406
Filed: 1983-06-28
Abstract: The oxygen probes are used to measure oxygen. Exhaust gases, carburisation gases and other carbon-containing gases, however, corrode the gas electrode of the probe. Quartz and corundum dust act as a sand jet in the furnaces with gas circulation. The gas electrode of the known probes is therefore gradually ground away, although other components are still serviceable for many years. The novel oxygen probe has a plurality of protective devices, all of which comprise an impermeable ceramic wall which deflects the gas flow from the electrode metal. In this way the result is achieved that soot and dust particles are kept away as a result of the centrifugal force, the electrode is only exposed to the gas flow at the point where the probe voltage is produced, and the actual metal of the electrode forms a metal matrix in a ceramic matrix and can therefore only corrode at the surface. Fortunately, the heavier molecules are corrosive and they are also deflected from the electrode.

Title: Temperature-stabilised isothermal process chamber with automatic process-heat control
Inventor: VINZ PETER DR ING
IPC: F28D15/06
Filed: 1983-12-09
Abstract: A method is presented which permits control of the process heat of one or more simultaneously operated, temperature-stabilised, isothermal process chambers, without there being a need to change the heating surfaces or the operating temperature of the process chambers. The process chambers work with the aid of evaporating heat transfer media in accordance with the heating tube principal. A particular feature of the method is that the size of a process chamber is no longer limited by the capillary suction capacity of the heat transfer medium, that it is possible to assemble from a plurality of heating tubes temperature-stabilised, isothermal process chambers of arbitrary size whose heating capacity is regulated in accordance with the process heat required, and that the temperature stabilisation is carried out using a hermetically closed inert gas pressure-maintaining system, independently of external supply devices.
