Patent DE-1941938-A1 (DE)
Title: Pneumatic-hydrothermal drying and firing - of ceramic prods and silicate building mat-erials
Inventor: HANS HOHMANN DR-ING
IPC: F26B3/06
Filed: 1969-08-18
Abstract: The raw products are simultaneously dried and fired in an electrically heated, gas-tight unit. The charge-firing material is first heated without appreciable dehydration to 1-160 degrees C and then dried with vapour temps. of 1-200 degrees C and water vapour partial pressures of 0.1-6 atm. The material thus dried is heated to 550-950 degrees C at water vapour partial pressures of 0.1-6 atm. While this temp. is maintained final firing takes place, followed by cooling the firing material and unit. The water vapour escaping from the charge or firing material during the entire combined process is utilized as a drying medium in the drying phase and as a decisive parameter in the firing phase. This is effected by using fans to force the vapour, under an excess pressure of 0.1-6 atm. in the gas-tight apparatus, through the charge-firing material, formed as a hollow product, to generate convective heat and material transfer.

Patent DE-2022454-A1 (DE)
Title: Cyanogen prodn by oxidn of hcn
Inventor: HEILOS JOHANNES
IPC: C01C3/00
Filed: 1970-05-08
Abstract: Cyanogen is prepd by the catalytic oxidn of HCN with H2O2 in the presence of cupric bromide, cyanide or nitrate.

Title: Corticosteroids microbiological 1,2-dehydrogenation
Inventor: PECHANY ISTVANNE DR UDVARDY GE
IPC: C12P33/00
Filed: 1970-08-24
Abstract: In a process for 1,2-dehydrogenation of corticosteroids with Arthrobacter or Corynebacterium species involving enzyme-induction subsequent to cultivation but prior to dehydrogenation, the induction of the steroid 1,2-dehydrogenase is begun by addition of 0.02-0.2 mg/ml of a steroid of the androstane or pregnane series only after the growth of the bacteria in the stationary phase of the culture, an amount of a C- and /or N-source such as to give a 0.01-0.1% concentration being simultaneously added to the culture so as to give rise to a secondary growth. A 1,2-satd. corticosteroid is added to the resulting highly active culture (which can be diluted before the addition), the dehydrogenation and the isolation of the product being effected in a conventional manner. The new method of induction gives very high enzyme levels, and the dehydrogenation proceeds extremely rapidly and is unaccompanied by steroid degradation or reduction.

Title: Encased plastics storage reel - houses developed film strip, for easy dispensing
Inventor: HONERKAMP JOHANNES
IPC: G03D15/00
Filed: 1973-06-30

Title: Increased lift wing profile - having raised upper flap on front of profile and hinged flap spaced from rear
Inventor: BARTOE JUN OTTO EDWIN
IPC: B64C3/48
Filed: 1973-12-06
Abstract: The lift of the wing profile is increased in a simple, effective way with the front, top leading edge of the wing lifted at its rear end, pivoted about the leading edge of the wing. Air is scooped into intake ducts and ducted through the hollow front edge to spill out of the raised flap and over the top of the wing. This increases the lift. Further advantage can be obtained by trailing flaps pivotted behind the wing edges at some spacing from them. Even more lift can be generated by auxiliary surfaces above the leading flap and trailing edge.
