Patent DE-3204460-A1 (DE)
Title: Resorption heat pump
Inventor: SALZMANN FRIEDHELM
IPC: F25B30/04
Filed: 1982-02-09
Abstract: In a resorption heat pump, the refrigerant contained in an absorption solution is drawn off as a gas via the gas chamber of an expeller exclusively by creating a low pressure by means of a jet pump. The jet pump is built into the supply line of a pressure pump, which line is connected via a counterflow temperature changer to the resorber, in such a manner that the absorption solution, which is low in refrigerant and is pumped off from the liquid chamber of the expeller, is enriched at the jet pump with the gas and can be pressure-relieved by a control valve for entry into the resorber. The counterflow line of the temperature changer coming from the resorber is connected to the expeller, in the liquid chamber of which there is installed a heat exchanger provided for carrying off the usable heat.

Title: Expansion vessel for the cooling or insulating fluid of large transformers
Inventor: PAIL WERNER
IPC: H01F27/14
Filed: 1982-02-22
Abstract: In order to prevent long-term adverse influences on the fluid by the moisture and oxygen contained in the air, the fluid surface is often completely covered in a gasproof manner by a membrane (9), for example in the shape of a sack. According to the invention, this sack-shaped membrane (9) consists of rubber mats which are vulcanised to one another at the edges and are flat in the unloaded state, and the spatial shape of the jacket (6) of the expansion vessel, which is composed of metal sheets, corresponds to the shape of the membrane (9) when it is stressed from the interior by a small excess pressure. The shape of the expansion vessel and of the associated sack-shaped membrane (9), which are matched to one another according to the invention, can be used expediently when absolute separation of the fluid from the atmospheric air is necessary to the extent that special requirements are additionally placed on the long-term resistance of the fluid. <IMAGE>

Title: Ultraviolet spectral hygrometer for determining gas humidity
Inventor: MARTINI LOTHAR DIPL PHYS DR
IPC: G01N21/33
Filed: 1982-06-12
Abstract: The UV hygrometer is particularly suitable for measuring the absolute humidity of gases which are stored or transported under overpressure and of gases having a medium to very high moisture content. The object of the invention is to provide a highly sensitive UV hygrometer for the precise, continuous and almost inertia-free measurement of the absolute humidity of gases which has a very wide application. This is achieved by using an atomic line radiator having a wavelength range from 140 to 190 nm, a measuring cell having radiation-transparent windows and a spectrally selective photoelectric receiver. A beam splitter situated between the atomic line radiator and the measuring cell splits the beam emerging from the atomic line radiator into a measuring beam and a reference beam. <IMAGE>

Title: Arrangement for generating pseudo-ternary signals free of direct current
Inventor: MEYER FRITZ DR ING
IPC: H04L25/49
Filed: 1982-06-30
Abstract: Pseudo-ternary signals free of direct current can be obtained in familiar manner from signals present in binary differential code by means of a stub line shortcircuited at the end. At low bit rates the stub line needed has a considerable length, and at higher bit rates the stub line can cause interference due to radiation of pulse components and interference can also be inserted due to irradiation. An arrangement is therefore proposed which contains a delay section and a subsequent differential amplifier arrangement and can be constructed fully electronically. The arrangement according to the invention can be advantageously used in the line terminating units and the regenerative repeaters of transmission links for digital signals. <IMAGE>

Patent DE-3244403-A1 (DE)
Title: Container made from an elastic synthetic material
IPC: B65D1/09
Filed: 1982-12-01
Abstract: A container made from an elastic synthetic material has a tubular metering chamber (2) for accommodating a material medium which can be removed from the container, which chamber is constructed such that the material medium remains in the metering chamber irrespective of position of the container, and a compressible container part (6), for accommodating a gaseous medium, which has a larger volume than the metering chamber. The two media have a mutual relationship such that, upon compression of the container part, the material medium located in the metering chamber can be expelled from this metering chamber through an opening provided thereupon. In order to use, and render suitable, the container for a medium with which the risk exists that after emptying of the metering chamber there will remain in the container an excessive residue which cannot be brought into the metering chamber and is therefore lost in practice, the material medium has - at least at ambient temperature - a pasty consistency and is located virtually exclusively in the metering chamber. The compressible container part is filled virtually exclusively with the gaseous medium. The entire material medium located in the container can be virtually entirely expelled from the container by a single complete compression of the container part (drawing). <IMAGE>

Title: Refractory and radiation-repelling lightweight building material and method for the production thereof
IPC: C04B28/26
Filed: 1983-02-01
Abstract: The refractory and radiation-repelling lightweight building material for the production of panels, blocks and similar shaped parts containing one or more fine-grain mineral fillers and an inorganic binder is characterised by the following composition, based on 0.1 m<3> finished material: 39.33 % by weight perlite, 20.23 % by weight kaolin, and 40.44 % by weight water glass with an expansion agent. Instead of perlite, expanded shale can be selected as main filler. The method for the production of refractory and radiation-repelling shaped parts, particularly panels, from the new material is characterised in that the mineral fillers perlite or expanded shale, kaolin and possibly mineral fibres, hardeners and the binder water glass, which contains an expansion agent, are stirred together homogeneously in a mixer at room temperature with foaming of the water glass, and the mixture is then compacted into shaped bodies, for instance panels, and dried.
