Patent DE-3434097-A1 (DE)
Title: Process for waterproofing walls
IPC: E04B1/64
Filed: 1984-09-17
Abstract: In the case of a process for waterproofing walls (1), a continuous cutout is first of all made in the wall in order to form a gap (6) of predetermined width, and the gap (6) is filled with mortar (8). Thereafter, barrier plates (11) are driven into the mortar, which is still moist, so as to be located flush against one another or to overlap one another. The barrier plates (11) consist of profiled stainless sheet steel and, before installation, have a profiling height which is equal to, or greater than, the gap width (b). As a result, the pressure received from the wall part (1b) located above the mortar (8) is transferred to the barrier plates (11), in particular before the mortar has set, as are the shear forces between the lower wall part (1a) and the upper wall part (1b), after the mortar (8) has set. <IMAGE>

Title: Arrangement for inserting a cable into a housing
Inventor: KROENER HOLGER
IPC: H02G3/06
Filed: 1984-10-31
Abstract: An arrangement for inserting a cable into a housing, preferably a circular-cylindrical housing for electrical or electronic apparatuses, is shown and described. The housing is provided with a circular-cylindrical housing part which is constructed for the connection of the connecting cable in a detachable manner. This housing part is split in two into the insertion collar 6 and into a cover 4 which covers the electrical connecting elements. The insertion collar 6 is supported in the rear wall of the cover 4 such that it can rotate continuously. Thus, the connecting cable can be inserted into the apparatus, in accordance with the on-site requirements, bent into any angular position from a position which is axial with respect to the longitudinal direction of the electrical apparatus, up to 90 DEG . A single screw 5, which passes through the outer surface of the cover 4, is used for mounting the cover 4 on the housing 2 of the apparatus 1. In order to ensure sealing, sealing surfaces and webs are integrally formed which connect the housing part 4 in a sealed manner to the housing part 2, with the interposition of a moulded seal 40, with the screw 5 being tightened in a radial direction. The insertion collar 6 is removable and, if it is necessary to replace the PG screw union, can be replaced for a collar whose internal thread 65 corresponds to the external thread of the desired PG screw union. <IMAGE>

Title: Process for producing a desired redox potential for flue gas scrubbing by utilising a liquid metal granule-fluidised bed reactor technique
Inventor: HOELTER HEINZ DIPL ING
IPC: B01D53/60
Filed: 1985-01-28
Abstract: It is known that for the simultaneous separating out of SO2 and NOx from flue gases, the redox potential must be moved in a controlled manner in the negative range. Additives, such as sodium dithionite, are employed for adjusting the liquid. It is further known to control the redox potential electrolytically and/or by means of an iron reactor. In order to ensure a high availability of flue gas desulphurisation plants, according to the invention it is proposed that metal granule spheres are added to the scrubbing liquid in the direct scrubber sump or in a by-pass and the scrubbing liquid is passed through a fluidised-bed reactor technique in which the iron granules take on the task of controlling the redox potential. The housing of the fluidised-bed reactor can be composed of an insulated vessel, so that the mixture of liquid and metal granules can be electrolytically controlled as a fluidised bed.

Patent DE-3514155-A1 (DE)
Inventor: SCHMITT WALTER ING GRAD
IPC: H03K5/04
Filed: 1985-04-19
Abstract: A process and apparatus for use in digital length or angle measuring systems for regulating the keying ratio of at least one periodic electrical signal. A signal is produced, proportional to the desired keying ratio, and compared with the periodic electrical signal. A momentary difference signal is generated from the comparison. If the frequency of the periodic electrical signal is within a selectable frequency range, the momentary difference signal is applied to a correction circuit, which is circuited parallel to a storage unit. The correction circuit supplies a correction signal, based on the momentary difference signal, to a sum amplifier. The sum amplifier is operative to superpose the correction signal on the periodic electrical signal, thereby regulating the keying ratio of the periodic electrical signal. The storage unit is operative to store a signal proportional to the difference signal. If the frequency of the periodic electrical signal is outside the selectable frequency, the correction signal is derived from the contents of the storage unit.

Title: Process and equipment for preheating scrap to be introduced into an electric furnace
Inventor: FOERSTER ECKEHARD DR ING
IPC: F27D13/00
Filed: 1985-06-15
Abstract: In a process for preheating scrap to be introduced into an electric furnace, the scrap is filled into a scrap basket and the filled scrap basket is introduced into a preheating furnace. The sensible heat of furnace gases extracted from the electric furnace is used for preheating the scrap. The furnace gases are then released into the open via a dust removal installation. The furnace gases extracted from the electric furnace are, on the way to the dust removal installation, passed through a heat exchanger which is a part of a preheating-gas circulation for the scrap preheating. The preheating gas is passed via the preheating furnace and through the scrap basket. In accordance with the loading of the preheating gas in the preheating-gas circulation with pollutants, a part stream of the preheating gas is mixed in the hot zone of the furnace gases into the latter, where the pollutants are burned. Preheating gas is correspondingly replaced by fresh preheating gas. <IMAGE>

Patent DE-3530511-A1 (DE)
Title: Pedicure sandal
IPC: A43B7/26
Filed: 1985-08-27
Abstract: The flexible spacer cams on the elastic walking sole determine the requisite distance of the toes during individual treatment of the toenails as part of pedicure. The treatment can be interrupted at any time and resumed, that is the feet can be used in between for their original purpose (walking) without adversely affecting the cosmetic treatment. When worn as a leisure shoe the sandal gives the feet relaxation, recovery and a healthy feeling of freshness. These properties are due to the elastic walking sole and the flexible spacer cams. By shifting the weight of the particular foot during walking the toes are spread apart and put together again, on the one hand, and there is an upward and downward movement on the spacer cams at the same time. These rhythmic sequences bring about good blood flow and massage and exercise for the entire foot.

Title: Bonded splice for connecting ends of two optical fibres in a guide element
Inventor: BECKER JOHANN
IPC: G02B6/38
Filed: 1985-10-22
Abstract: The invention relates to a bonded splice for connecting the ends of two optical fibres in a guide element in which there is formed along juxtaposed cylindrical glass rodlets a free interstice whose inside circular diameter is substantially greater than the outside diameter of the ends of the optical fibre which are freed from their protective coating and are to be introduced. They are introduced in a bent position in such a way that they are pressed elastically into a common guide groove formed between two adjacent glass rodlets. A guide element of uncomplicated design can be used to produce an accurate spliced joint in a simple way owing to the fact that the glass rodlets (1, 2 and 14, 15) forming the guide groove project on both sides beyond the remaining elements (3 and 16) forming the interstice. <IMAGE>

Title: Vacuum regulating unit
Inventor: LARSSON KARL OLOF AXEL HELMER
IPC: A61M1/00
Filed: 1985-11-11
Abstract: The unit is a combination of a leakage-air and a diaphragm regulating unit. A valve-closing element (14-17, 20) is moved into the closing position (18, 19) by the set point adjuster (3-5) under spring loading. Acting counter to this motion is a diaphragm (23) serving as a servomotor (22) which is acted upon by the vacuum. When the desired vacuum has built up, the valve (18, 19) is closed, with the result that the desired vacuum is rapidly achieved. Due to the spring loading (8) of the valve-closing element, the entire adjustment range of the unit can be covered in less than one revolution of the set point adjuster (5) and, as a result, rapid setting, adjustment and reproducibility of a desired vacuum value is achieved by means of a scale and an index mark therefor. <IMAGE>
