Title: Water-soluble ammonium polyphosphates prodn. - by two-stage thermal decomposition of urea phosphate
Inventor: THEOBALD HEINZ DR
IPC: C05B13/06
Filed: 1973-02-21

Patent DE-2408109-A1 (DE)
Title: Petri dish for high packing density - in incubator has deepened peripheral groove with rib for condensate
Inventor: VOGEL H L DR
IPC: C12M1/22
Filed: 1974-02-20
Abstract: A petri dish for use in microbiology as receptacle for nutrient media has around the central part an annular condensate collection groove with a bottom deeper than the central part. A rib above the annulus prevents the condensate from escaping when the dishes are put into the incubator in a vertical posn. A disc of absorbent material resting on the rib can be used to keep the cover free from condensate. This allows the Petri dishes to be arranged in an incubator in a vertical posn which results in a greater capacity of an incubator without impeding the rising heat circulation.

Title: Safety wheel rim for tubeless tyre - having hard rubber layer over rim and edges attached by vulcanisation
Inventor: PRUSS GUENTHER MANFRED
IPC: B60B21/10
Filed: 1974-03-27
