Title: IC engine cam timing modification system - uses pulleys on sliding arms to vary effective length of drive belt
Inventor: PIECH FERDINAND DIPL ING
IPC: F01L1/344
Filed: 1977-10-26
Abstract: The performance of an internal combustion engine is improved by modifying the timing sequence for entry of gases into the combustion chamber by altering the position of the cams. The belt (40) which is driven by the crankshaft (38) and which drives the camshaft (42) also passes over an adjusting roller (46). This is in line with a tensioning roller (48). The latter is mounted on an arm (52) with a spring (54) behind it, able to slide inside a lever (50) which carries the adjusting roller (46). The movement of the lever (50) to and fro is controlled by the accelerator pedal. This varies the effective length of the belt.

Title: Straw dehydration machine - with impact rotor for crushing and centrifuge for solids-liquid separation
Inventor: WIENEKE FRANZ PROF DR ING
IPC: B02C13/06
Filed: 1978-03-14
Abstract: A machine for the mechanical preparation and dehydration of straw and stalks treats the charge continuously in an ultra-frequent compression-expansion process. Solids and liquids are finally separated in a centrifugal field. Two parallel worm conveyors pref. take the material to a space where foreign matter can accumulate and, when the pressure becomes excessive, burst a shear pin to be discharged. A limit switch cuts off the drive; a second one responds when the tunnel is overfull. This machine combines a higher efficiency with a smaller constructional effort and a lower power consumption. The crushing section consists of a rotor with the impact tools and a split stator with two halves and ribs. Transfer slots move the material to the centrifuge on the same drive shaft. The blades of the centrifuge are preceded by guide discs. Liquid and solid residue are discharged through separate channels.

Patent DE-2931999-A1 (DE)
Inventor: SIEWERT GERHARD DIPL CHEM DR
IPC: C12N9/16
Filed: 1979-08-03
Abstract: PhoA mutant E. coli SB44, prepared by mutation of E. coli HB101 with an N-nitroso compound, can be used to identify and isolate recombinant plasmids into which a phoA gene has been incorporated. These plasmids can be used to transform bacteria which can be cloned and incubated to provide alkaline phosphatase in high yield. Moreover, these plasmid vectors can be modified in various ways so that the N-terminal amino acid sequence of phoA is followed in reading phase by the DNA coding for some other protein. In turn, these new plasmids can be used to transform bacteria which can be cloned and incubated to produce fusion proteins comprising the desired other protein in high yield and outside of the cell membrane in the periplasmatic space.

Title: Composite, high strength prods. contg. aluminium and glass - where blank made from aluminium and glass powders is hot pressed to obtain prods. with fibrous structure
Inventor: BERGMANN HANS-WILHELM DR
IPC: C03C14/00
Filed: 1980-01-14
Abstract: Powder metallurgy is employed to make a composite blank contg. Al and glass powders. The blank is then moulded or pressed into a desired shape using a process in which the Al is deformed by the pressure of the molten glass. The glass is pref. selected so both the Al and the glass have the same resistance to deformation at the moulding or pressing temp. The amt. of glass employed in the blank is pref. employed to control the coefft. of thermal expansion of the composite material; and the type of glass used pref. ensures wetting of the Al so tha high strength is also obtd. in a direction at 90 deg. to the pressing direction. The pressing temp. of the blank pref. depends on the amt. of deformation required. Aluminium and glass are readily available in large quantities; and the invention produces a material or prods. in which a low density is combined with high strength.
