Filed: 1987-08-25
Abstract: The clamping element comprises a cylindrical part, having a bore for the cylinder axis for receiving an axial connecting screw, and, on the cylinder casing, a pair of rigid jaws which are arranged parallel to the axial bore and the spacing of which is greater than the thickness of the panel-type structures which are to be connected, an adjustment screw being provided on one jaw in order to press and secure the panel-type structure against the other jaw. Various fittings can be produced using one and the same type of clamping element, in order to fit together a different number of panels at essentially any angles along rectilinear boundary lines. The system of fittings is, in particular, useful for setting up racks or display walls for fairs and exhibitions.
Patent DE-3728676-A1 (DE)
Inventor: MCDOWELL THOMAS LEWIS
IPC: G01R31/00
Filed: 1987-08-27
Abstract: In measuring armature overtravel in electromechanical relays, the times T1, T2 of the closure of the moving and stationary contacts (24, 22), and of the armature hitting its stop, are determined and the interval (T2-T1) between these two events is measured to obtain an indication of the overtravel distance. As shown, a voltage Vo changes abruptly when the contacts (24, 22) close (T1), and the relay coil coil current Ic, as sensed at a resistor (36), exhibits an inflection (46) when the armature (14 Fig. 1 not shown) strikes a stop (34) at time T2. <IMAGE>

Title: Use of a catalyst based on modified zeolite, charged with one or more metals from the group consisting of Fe, Cu, Ni and Co, in the SCR process
Inventor: DEUTZ WOLFGANG DIPL ING
IPC: B01J29/24
Filed: 1988-02-01
Abstract: By the use of a catalyst based on modified zeolite of the Y or mordenite type, charged with one or more elements from the group consisting of Fe, Cu, Ni, Co and K, a sequential DeNOx/DeNH3 catalytic action can be achieved in the SCR process for NOx reduction in furnace exhaust gases. These catalysts have the property of simultaneously catalysing two reactions, that is the NOx reduction with NH3 and the NH3 oxidation with oxygen, depending on the concentration of NOx in the gas to be treated, in such a manner that at high NOx concentrations, the NOx reduction with NH3 is preferentially catalysed and at low NOx concentrations, the NH3 oxidation is preferentially catalysed. These catalysts permit NH3/NO ratios up to 1.2 times the stoichiometric amount, convert up to 98% of the NO and ensure an NH3 slip below 5 ppm via the sequentially preceding oxidation of the residual NH3. For treating SO2-free gases in the SCR process, the use of the catalyst at gas temperatures in the range between about 80@C and about 500@C is suitable, and when treating SO2-containing gases, the gas temperature range between about 200@C and 500@C is suitable.

Title: Built-in components for a high-temperature reactor accommodated in a prestressed concrete pressure vessel
Inventor: KOLODZEY JUERGEN DIPL ING
IPC: G21C1/07
Filed: 1989-01-11
Abstract: The invention relates to the built-in components of a high temperature reactor, consisting of the thermal cover shield and the cover reflector, which are arranged above its core and are suspended by means of tension rods. The tension rods which hold the thermal cover reflector, consisting of a layer of hexagonal cover stones, are fastened onto the pressure vessel lining. Each cover stone is suspended on three tension rods. In order to prevent cover stones being able to fall down upon failure of the suspension, each cover stone has three claws, directed radially and arranged at 120@ to each other, which engage behind the neighbouring cover stones, and the claws of three neighbouring cover stones engage behind each cover stone. The cover reflector consists of multilayer hexagonal columns of blocks. In each case, a unit consisting of three of these columns of blocks is suspended on the thermal cover shield by means of a central tension rod, the three columns of blocks being held by a carrier plate arranged at the lowest layer and connected to the central tension rod, as well as in each case by a tension anchor. The tension anchors are designed as pipes and accept, in each case, a tension rod guided in its further course through the column of blocks and fastened on the thermal cover shield, so that each column of blocks of the cover reflector is likewise redundantly suspended. A plurality of variants are specified for the fastening of the tension rods in the lowest layer of the column of blocks.

Title: Electrically controllable hysteresis coupling
Inventor: SCHNEIDER RUDOLF
IPC: H02K49/06
Filed: 1989-02-21
Abstract: The electrically controllable hysteresis coupling (HK) which intrinsically operates in accordance with a generally known principle is designed without hub rims from the coil housing (4) and pole ring (6) so that the coil (5) directly encloses the input drive shaft (1), which is made of material which can be magnetised, with only a small amount of play. The pole ring (6) and armature (7) are arranged axially downstream of the coil housing (4) and the coil (5) is designed to be elongated. This results in the coupling parts having an external diameter which is so small that they can necessarily be pushed completely axially into an internal cavity in the output drive shaft (8), concentrically with respect to the input drive shaft (1). This also enables the retrofitting of hysteresis couplings between existing shaft supports with a reduced material cost, because no additional axial space is required. In addition, extensions to the possibilities for use and savings in manufacture result. <IMAGE>

Inventor: MIKOS JEROME JOSEPH
IPC: G10H7/00
Filed: 1989-11-13
Abstract: A digital data synthesizer has a phase accumulator 8-64 into which adjustable step increments are clocked. The output of the phase accumulator addresses a memory 72, in which a waveform function is digitally stored. Samples read from the memory at the successive addresses are converted 82-86 to analog form and filtered 108 to produce a final output signal of a desired frequency. Register stages 54-64 of the phase accumulator are pipelined to increase speed. The digital-to-analog converters 82-86 are all on a single chip to equalize the delay times occurring within them, to improve resolution and reduce noise. A RAM lookup table 72 permits a variety of output waveforms to be loaded and generated. One embodiment has a plurality of lookup tables for the same waveform, stored with different phase spacing between addresses, and a decoder/addresser for automatically selecting the lookup table that results in the best performance for the required output frequency. The output of a correction table may be combined with that of the main table to produce an analog signal of reduced distortion. A plurality of such correction channels, that are automatically addressable, may be provided. <IMAGE>
