Title: Bicycle fork retainer for loose wheel - has projections bent outwards to retain axle when nuts are slackened
Inventor: HESS STANLEY
IPC: B62K25/02
Filed: 1979-05-19

Title: Electrohydraulic servo valve with proportional pressure control - achieved by mechanical return spring and spring-centred 4-3 way valve
Inventor: KUCHARZYK REINHARD ING GRAD
IPC: F15B13/04
Filed: 1979-10-23
Abstract: The valve sets the desired value as an electrical quantity in the control solenoid exerting an appropriate force on the armature rod and, with this force, sliding the control piston against the mechanical return spring so that the control piston allows the control pressure medium to flow from a connection point to a second connection point and on into an operating chamber of the hydraulically operated, spring-centred 4/3 valve. The control piston then slides out of its middle or rest position and allows the pressure medium to flow from a third connection into a fourth or fifth connecting so that the throttle piston is moved out of its rest position.

Title: Joint between tilting driving cabin and engine compartment - includes channel forming labyrinth seal for noise reduction at hinge point
Inventor: BAYER ULRICH
IPC: F16J15/447
Filed: 1979-12-22
Abstract: To obtain access to the engine compartment of a goods vehicle, the driver's cabin is tilted backwards.

Title: Protein-contg. material prepn. by aerobic microorganism fermentation - and waste gas supply for carbon di:oxide-assimilating plant growth
Inventor: HEISEL MICHAEL DR
IPC: C12N1/00
Filed: 1980-02-08
Abstract: Protein-contg. materials are prepd. by cultivating microorganisms utilising O-, C- and H-contg. materials under aerobic conditions, in an aq. medium contg. O2, C- and H-contg. materials, in a fermentation vessel. Novelty consists in drawing the waste gases formed in bio-mass cultivation out of the fermentation vessel and charging them to a chamber in which are grown CO2-assimilating plants. The plants can be cereals, which supply a high starch quantity, or protein-rich algae, pref. of Chlorella and Spirulina species. In a pref. process, the waste gases are charged to an algae-contg. nutrient medium, suitable for algae cultivation. The prods. are used in human- and animal nutrition. In charging the CO2-contg. waste gases to plants utilising CO2 for protein and/or carbohydrate synthesis, protein prodn. is increased and a better use is made of C-sources.
