Patent DE-3443509-A1 (DE)
Title: Evaporation arrangement
Inventor: PELTONEN SEPPO SIMO OLAVI
IPC: B01D1/06
Filed: 1984-11-29
Abstract: The invention relates to an evaporator which operates by the falling film principle and is composed of a long tube. The evaporator according to the invention is equipped with a separator component (5) located in the top part of the arrangement, a separator component (4) located in the bottom part of the arrangement, a connection tube (3) between these two components, a liquid space (6) and heat exchange tubes (1). The separator component (5) and the liquid space (6) form one and the same space, for which reason the pressure is also the same in the two components. As a result of the connection tube, the pressure in the separator component (4) and that in the separator component (5) are also identical. The invention also relates to a process for evaporating liquids using the arrangement mentioned.

Title: Punking-free mineral fibre product
Inventor: SCHIRMEISEN JOSEF DIPL CHEM
IPC: C04B26/12
Filed: 1984-12-03
Abstract: Use of a mineral fibre product which has been treated with an aqueous solution of a melamine/formaldehyde precondensate which is esterified with an aliphatic alcohol having 1-4 carbon atoms, for the heat insulation of highly heated fluids at temperatures above 400 DEG C. This mineral fibre product shows no punking behaviour, that is to say it can be used at these high temperatures especially for the heat insulation of pipes bearing heated fluids.
Patent DE-3444893-A1 (DE)
Inventor: LEPPER HERBERT DR
IPC: C11C3/04
Filed: 1984-12-08
Abstract: Fatty acid alkyl esters are produced by catalytic transesterification of natural fats and oils containing free fatty acids. In a preliminary esterifying step, the free fatty acids present are reacted with a C1-C4 alkanol (e.g., methanol) in the presence of an acidic esterification catalyst, at a temperature of about 50 DEG  to 120 DEG  C. and at substantially atmospheric pressure. The resulting reaction mixture is allowed to separate into two phases: (1) an alcohol phase containing the acidic esterification catalyst and part of the water of reaction and (2) an oil phase. These phases separately recovered. The oil phase is then extracted with an immiscible extractant, preferably comprising a mixture of glycerol and methanol, to remove residual water of reaction. In the final step the extracted oil phase is transesterified with a C1-C4 alkanol, e.g. methanol, in the presence of an aklali catalyst and at substantially atmospheric pressure.

Title: Method and device for ultrasonically testing for incipient cracks slotted screws turned into a top fitting of a nuclear reactor fuel element
Inventor: SCHARPENBERG RAINER DIPL ING
IPC: G01N29/22
Filed: 1985-02-09
Abstract: In such a fuel element top (1) ultrasonic testing of the recessed head screws (3) turned in at that location is attended by problems, since the slots of these screws can falsify echo signals from possible incipient cracks (4) in the transition region between the screw head and screw shaft. In order to obtain perfect echo signals, a test head (21) is applied separately to each region of the end face of the slotted screw (3) bounded by a slot, and the screw head is acoustically irradiated in the direction of the suspected incipient cracks (4). <IMAGE>

Patent DE-3508918-A1 (DE)
Title: Sunshade apparatus
Inventor: CLAUSS MANFRED
IPC: E06B9/92
Filed: 1985-03-13
Abstract: The sunshade apparatus has two guides which are located opposite each other, at a distance apart, and are parallel to each other. A guide part on which in each case one opening-out arm is articulated can be displaced along said guides. The guides can be pivoted by about 180 DEG  from an upright position into a hanging position and are connected to each other by an opening-out tube. In the movement path of the opening-out arms there is located on the guides in each case one pivoting device having a spindle to which there is assigned on the opening-out arm in each case one abutment which, together with the spindle, forms a fixed rotary spindle during the pivoting process. After the hanging position has been reached, the opening-out arms are displaced further downwards from the spindles of the pivoting device. As a result of this displaceability, the pivoting devices need no longer be precisely mounted on the guides, when mounting the sunshade apparatus, since the opening-out arms with the guide parts can be let down to such an extent that a window, a door or the like is completely covered.

Patent DE-3544540-A1 (DE)
Title: Slatted blind
Inventor: BAUMANN WILLI
IPC: E06B9/325
Filed: 1985-12-17
Abstract: The slat ends in this slatted blind are guided laterally in rails. The slats are lifted and drawn together by means of lifting cords. On one slat (5), normally both slat guide ends are equipped with a locking means (28, 29) which can be actuated by a pivoting movement of this slat (5) and makes it possible to lock the blind (1), in particular in the lowered state. In the closed state, with the principal slat surface parallel at least approximately to the guide-rail longitudinal axes, this slat (5) holds the locking means (28, 29) in the locked state. This locking means frictionally locks the blind and thus prevents it from being raised. The locking means (28, 29) develops an increasing locking force when subjected to increasing blind-opening force in the locked position. This locking means has, as locking elements, rollers (28, 29) which can be actuated by means of an oblique member which can be displaced relative to the locking element and is in the form of a wedge. This structure does not require any special chains or cords for locking purposes. It is simple, functionally reliable and inexpensive. <IMAGE>

A probe lever (25) which is supported such that it can pivot is used for displacing the rod (26) and can be operated, for example, by a control device which is located on a drawer support in the power circuit breaker. A modified embodiment (50) of the arrangement can furthermore be constructed such that two carriages (14, 51) are provided which can be influenced by one rod (64) or two rods (26, 55) in order to bring about both opening of the switch contacts and relief of a connection store. <IMAGE>

Title: Method for improving the selectivity of spectrometric measurements, and device for carrying out the method
Inventor: CAMMANN KARL PROF DIPL CHEM DR
IPC: G01J3/433
Filed: 1986-05-22
Abstract: In the case of spectrometric measurements, the selectivity, i.e. the ratio of the signal which is analytically proportional to the signal which is proportional to the foreign matter, plays a substantial role. When a narrow spectral band is filtered out of the spectral region to be investigated by means of filter arrangements or the like and fed to a detector whose output signal is displayed, the result is a substantial improvement in selectivity owing to the fact that the filter arrangement is periodically shifted with respect to the spectral region to be investigated in such a way that the spectral band which passes through the filter arrangement is periodically shifted via the spectral region to be investigated, and that the detector output signal is displayed via a lock-in amplifier whose phase reference signal is proportional to the shift.
