Title: Non-CFC blowing agent for prodn. of foamed prods - comprises hydrogen stored in hydride(s), released at elevated temp. and/or reduced pressure, for foamed rubber, expanded polystyrene, etc.
Inventor: BEHRENS ULRICH
IPC: C08J9/06
Filed: 1990-04-26
Abstract: Blowing agent (I) for the prodn. of foams and foamed prods. comprises hydrogen stored in hydrides, which is released when the hydride is exposed to heat and/or low pressure, thus producing the required increase in vol. with formation of pores. Pref. hydride material (II) is powdered metal at metalloid hydride (II) is homogeneously mixed with the substances to be foamed (III); pref. (II) and (III) are stored separately and only mixed when the foam is to be produced. USE/ADVANTAGE - Provides a non-CFC blowing agent which is harmless to the environment and can be used under the most variable conditions for the prodn. of various foamed prod. (I) contain large amts. of stored hydrogen, and residual hydride does not damage properties of the foam; the hydrogen rapidly diffuses out of the foam, leaving a material with low thermal conductivity. Used in e.g. structural or insulating-foam, foamed rubber, expanded polystyrene, porous concrete, etc.

Title: Measuring width of planks that can be cut from tree trunk -  moving distance measurers along line of cut on opposite sides of trunk at set spraying to supply valves continuously to computer
Inventor: HOFMANN KARSTEN
IPC: B23D59/00
Filed: 1990-08-29
Abstract: Two distance measurers (22,24) are placed on opposite sides of the tree trunk (16) to be cut into planks at a predetermined distance from each other. They are moved in their common measuring plane along the cutting line relative to the tree trunk. The measured distance values are continuously delivered to a computer (30). A length measurer (32) also supplies the computer with measurement values for the length of the path covered by the distance measurers continuously so that the computer can correlate both sets of values. The trunk can be moved while the distance measurers remain stationary. The latter can operate by laser-optics to conform to the laser triangulation principle. The beams (26,28) from the laser source are coaxial and assigned to a plane that coincides with the cutting plane of the saw. USE - Ascertaining best cuts to obtain most planks with straight edges from given tree. (4pp Dwg.No.3/3)
