Title: Water carrying roof tiles - connected to heat pump for independence from solar heat
Inventor: SIEMERS KARL-HEINZ
IPC: F24J2/04
Filed: 1980-02-16
Abstract: Roof tiles for heat recovery from ambient air are made of 1 mm thick sheets of an aluminium magnesium alloy or of polyester or of alloy steel and resemble conventional pantiles in their appearance. Each tile is equipped with a water inlet and a water outlet so that they can be coupled to each other and to a heat pump. This makes them independent of solar radiation and extracts heat from the ambient air because the heat pump keeps the roof temperature below outside temperature. It extracts even the heat from rainwater. In summer, the heat pump can be switched off to save power. This roof does not spoil the appearance of a house.

Title: Improvement of fertility in artificially inseminated animals - by intra:uterine infusion of components deficient in the genital secretion and/or antagonists of components present in excess (AT 15.6.81)
Inventor: HORVATH GEB BAKSAI
IPC: A61K33/42
Filed: 1980-05-13
Abstract: Use of equilibrating agents in the fertilisation of mammals in order to improve reproduction is new. The equilibrating agents contain effective amounts of (a) those components absent from the genital tract secretions of oestrous but infertile females but present in the genital tract secretions of oestrous and fertile animals in the same locality and/or (b) substances which tender inactive components present in excess in the genital tract secretions of estrous but infertile animals. The method is based on the finding that the genital tract secretions of oestrous but infertile animals differ in composition from the genital tract secretions of oestrous and fertile animals, showing in particular a deficiency in enzyme activators and/or substrates and an excess of calcium and/or magnesium ions. As enzyme-activating agents, the equilibrating agents pref. contain zinc, selenium, copper, iodine, iron and/or cobalt ions. As enzyme substrates, the agents pref. contain fats or fat-like substances, carbohydrates or proteins. As components to bind excess calcium and/or magnesium ions, the agents pref. contain chelating agents, esp. polyaminocarboxylic acids or their salts. Process is used for improving the success rate of artificial insemination of animals under conditions of intensive rearing.

Title: Permanent connection of lid to radioactive waste storage vessel - withstands later compaction of vessel and contents before final storage
Inventor: HOFHEINZ KLAUS
IPC: G21F9/36
Filed: 1980-11-14
Abstract: A permanent connection is made between a sheet metal storage drum for radioactive waste and its lid, to withstand later axial compression of the drum and contents, typically to one-third of its original volume, as follows. The lid has an axially inward projecting flange of greater axial depth than the corresponding flange or rim (I) surrounding the mouth of the vessel. The lid flange (II) has a radial inward recess or beading further down into the vessel than the bottom of the vessel flange (I). Flange (II) continues beyond this beading. The lid is pushed fully home into the opening until its rim bears on the vessel mouth. In subsequent axial compaction of the vessel, the lid flange (II) is deformed by contact with the contents of the vessel, so that it folds and engages beneath the surrounding flange (II) of the vessel mouth. For the first stage of the permanent storage of radioactive wastes, such as contaminated air filters, in drums which are to be axially compressed into concertina form, then later packed and cemented in a larger container. A firm connection is made between the lid and the vessel as the vessel is compacted, and thus the vessel remains tight.
Patent DE-3043238-A1 (DE)
Title: Missile search head for use against ground targets - has laser distance calculator for scanning target area contours
Inventor: SEPP GUNTHER DIPL PHYS DR
IPC: G01S17/08
Filed: 1980-11-15
Abstract: The missile is equipped with a laser range finder (1), a deflector system (12) and an electronic control (13). The laser (11) sends its beam to the target, e.g. a tank, and the deflector system guided by the electronic controls (13), forms a type of radiation raster (20a-20f) over the target area. The raster can also be laid continuously horizontally or vertically in the direction of flight (20a-20f, 21a-21e). The light scattered back from the target and the background, is picked up by a receiver (14) and fed to an evaluating unit (5) and distance change detector (16). Depending on the type of scanning method, a range profile is produced which is evaluated, the final output from the distance change detector (16) then being fed direct to the missile controller (17). Thus the missile is able to seek and track its target, making use of the distance jumps occurring against the background.

Patent DE-3106249-A1 (DE)
Title: Wet surface cleaner for ventilating and air-conditioning systems
Inventor: TISCHENDORF JOACHIM PROF DR
IPC: F24F3/16
Filed: 1981-02-20
Abstract: The invention relates to a process for cleaning the air in air-conditioning systems. In particular odours, gaseous air pollutants which are soluble in water, and dust are to be removed. The invention constitutes a development of the known contact-surface humidifiers. These are more advantageous than spray-jet washers owing to their lower space requirement and because the water atomisation is replaced by a pressure-free water distribution. The contact-surface humidifiers are well-suited for air humidification, but not for air cleaning. In order to avoid this disadvantage, the invention illustrated in the patent application comprises a contact-surface cleaner which has a very much larger specific surface area and is also operated by a very much larger quantity of water. Moreover, the water is, if required, cooled and kept clean more easily. For mist elimination there is connected, downstream of the contact-surface cleaner, a smaller, second part which is operated alone in the case of cleaner air which is only to be humidified and not cleaned. The cleaning device for exterior-air cleaning of air-conditioning systems is principally intended to be used in the case of inversion weather conditions in built-up areas.

Title: Process for producing a non-combustible lightweight concrete and moulded body obtainable by the process
Inventor: ECKARDT PETER DR
IPC: C04B28/02
Filed: 1981-03-19
Abstract: Lightweight concrete is characterised by a bulk density of less than 1.0 kg/dm<3> and high heat-insulating capacity. With decreasing bulk density, the thermal conductivity is reduced and the mechanical properties are usually impaired. A lightweight concrete which is non-combustible, has a bulk density of 200 to 450 g/l and has both good thermal insulation properties and satisfactory mechanical properties is obtainable if a water-soluble cellulose ether and an aqueous plastic dispersion with low solids content are used in its production. The foam composition obtained by this process hardens and forms moulded bodies with uniform porosity.
