Title: Mounting device of an optical waveguide (LWL) passage coupling on the front panel (assembly wall)
Inventor: MERKER KURT PROF DR SC TECHN
IPC: G02B6/36
Filed: 1988-08-09
Abstract: The invention relates to a mounting device for optical waveguide connector couplings (passage couplings) on the front panel (assembly wall) of apparatuses of the electronics industry. The mounting device consists of a holding segment of double U-shaped profile in which the triangular flanges of the optical waveguide connector couplings are placed, in each case rotated about 180@ about the longitudinal axis, held with a pressure tape, which corresponds to the profile of the holder frame segment, by means of snap-in pressure closure elements or pressed against one another in the guide which is located at the front panel (assembly wall) by lateral displacement of these assembly parts and thus locked with respect to each other. By means of this mounting device extremely short assembly and disassembly times are achieved for a group of optical waveguide connector couplings on the front panel (assembly wall) in conjunction with high mechanical strength of this connection. The assembly area required for each optical waveguide plug connection is extremely small and permits the implementation of very small grid dimensions (contact spacings) on the front panel (assembly wall). The mounting device makes it possible to replace the optical waveguide connector couplings, which are worn out after a predetermined number of insertions, in front of the front panel (assembly wall). It is not necessary to open the apparatus for this kind of servicing. The ... fitted with the optical waveguide connector couplings and arranged so as to be laterally displaceable in the guide of the front panel (assembly wall) ... Original abstract incomplete. <IMAGE>
Patent DE-3827837-A1 (DE)
Inventor: FECHNER RAINER
IPC: G04R20/14
Filed: 1988-08-17
Abstract: A continuous time-of-day or date correction of a signal produced by a clock module is obtained from the data in a video-text or teletext signal that contains accurate time-of-day and/or date reference information. When the video-text/teletext data contain such reference information, the data of the output signal of the clock module are compared, on a continuous basis, with the received video-text/teletext. In case of a deviation between the clock module data and the reference information, a correction signal is applied to the clock module and corrects the clock module.

Title: Electric heater for thermal treatment of single- or multi-phase fluids, with a pipe directly heated by electric resistance heating
Inventor: GREFE ALF
IPC: H05B3/78
Filed: 1988-11-02
Abstract: Electric heater for thermal treatment of single- and multi-phase fluids. The known electric heaters have:   - at high fluid temperatures and pressures large heating-tube wall thicknesses which do not optimally satisfy the electrical and process-technological requirements, - twice the heating-tube wall area compared with the new electric heater,   - expensive insulation to reduce heat losses, - extensive safety measures in order to ensure safe operating states (no fluid escape or air entry in the event of heating-tube fracture) in the case of excess pressure or vacuum operation.   These disadvantages are avoided by the new electric heater. The heating tube (1) is installed in the guiding tube (15) such that the fluid flows along the heating-tube wall on both sides. It is thus possible for the:   - heating-tube wall thickness to be designed optimally in terms of electrical and process-technological requirements,   - heating area to be halved.   Jacket tubes (7a-7x and 9a-9x), top cover (14) and flanges (23/24) lead the fluid from the outside inwards towards the guiding tube (15) in such a way that:     - the heat losses are minimised, - in the event of heating-tube fracture no fluid can escape or air enter.   The electric heater is particularly suitable for the operationally safe thermal treatment of flammable fluids at high temperatures and pressures and, at the same time, with low heat losses and small overall dimensions. <IMAGE>

Title: Aiding sabot sepn. from projectile - by pressurised cavity applying propellant gas directly to projectile base
Inventor: BISPING BERNHARD DIPL ING
IPC: F42B14/06
Filed: 1989-06-08
Abstract: The sabot (12) which holds a sub-calibre projectile (10) and which separates after firing has a support surface (16) engaging the projectile rear face (22).  To ensure unhindered sepn. after firing, a pressurisable gas cavity (20) is provided at the centree of the support surface and is rapidly filled with propellant gases via a feed channel (30) whose cross-section is at least six times smaller than that of the pressure cavity (20). The feed channel may be offset into an annular pressure cavity, and may also be barred by a thin membrane integral with the support surface. The pressure cavity may be augmented by a matching depression (28) in the projectile rear face.  The sabot may be divided into segments affixed e.g., by a spring clip and after firing splitting in banana-skin manner. ADVANTAGE - Avoids risk of projectile flight being affected by minor surface defects during sepn. of sabot.

Title: Sodium sulphate sepn. from spent flue gas desulphurisation soln. - by modifying evapn. and crystallisation to minimise chemical and energy consumption
Inventor: NEUMANN ULRICH DR
IPC: C01D5/00
Filed: 1989-12-16
Abstract: Sepn. of Na2SO4 from spent absorption soln. in flue gas desulphurisation with Na2SO3 soln. involves recovery of Na2SO4/Na2SO3 mix crystals (I) from a side stream of the spent soln. by evapn. and crystallisation. The novel features are that (a) (I) are converted to a soln. with a concn. between 25 (wt.)% and satn. with condensed water from the process; (b) the soln. is mixed with residual suspension (II) from stage (e), which is rich in Na2SO4/Na2S2O5; (c) crystals rich in Na2SO4 are sepd. from the mixed suspension and worked up; (d) the liquid remaining in stage (c) is treated with gas contg. SO2 so that the ratio of S-IV to Na in the liq. is 0.9-1.0; and (e) the liq. from stage (d) is subjected to evapn. and crystallisation, a soln. free from crystals is sepn. from the suspension and this soln. is added to the main stream of spent absorption soln., whilst the remaining (II) with a solids content of max 60% is recycled to stage (b). USE/ADVANTAGE - The process is more economical than usual, since the energy and chemical consumption are reduced, whilst the loss of re-usable Na2SO3 and the amt. of crude Na2SO4 formed are minimised.
