Patent DE-2939423-A1 (DE)
Inventor: ALEFELD GEORG PROF DR
IPC: F25B17/08
Filed: 1979-09-28
Abstract: In a system with at least one absorption heat pump, a working medium is generated in a generator or explusion unit by the input of heat energy of relatively high temperature, from an absorption material. The generated working medium is condensed in a condenser and then undergoes expansion in an expansion unit. The expanded, condensed working medium is evaporated in an evaporator with the input of heat energy at a relatively low temperature and the evaporated working medium is absorbed again, in an absorber, in the absorption material. The heat energy, used for generation of the working medium from the absorption material, is so stored for the heat pump that the heat energy, as taken from the store, is on hand at a temperature which is high enough for the generation of working medium from the absorption material. The heat store may preferably take the form of a sorption store, comprising a zeolite as sorption material and forming a part of a further discontinuously operated absorption heat pump. Such a heat pump, using zeolite and, preferably H2O as a working material system, is responsible, when used by itself, for a useful effect on producing useful heat (that is to say heat able to be utilized) at a relatively high temperature, as for example 80 DEG  to 100 DEG  C. and higher and, if desired, for producing cold as well.

Patent DE-3007686-A1 (DE)
Title: Three=dimensional fabric patterning - uses layer of foamed photo fluid to be activated by light
Inventor: WALTMANN ERNST
IPC: G03C1/74
Filed: 1980-02-29
Abstract: The photo layer applied to a fabric, to give a three-dimensional patterning, is in the form of a fine-foamed fluid which is spread evenly over the material. The evenly-spread foamed liq is exposed to light to give the patterned effect, which is then photographically developed and fixed. A foaming tenside is added to the fluid, which also contains a wetting agent and a stabiliser. The foam is developed to give bubbles with a dia of 0.01-0.5 mm, and to increase the fluid vol by 5-20 times. After the foamed fluid has been applied to the fabric, the foam structure is destroyed and the foam worked into the material. After application, the applied layer is subjected to selective light, in a succession, so that patterned layers are developed within the layer to give the three-dimensional pattern, with a variety of colour layers within the photo fluid cladding. The process gives a simple method for applying an even photo layer to a material.
