Title: IC engine ignition with engine dependent signal generator - has additional capacitor whose charge is variable via emitter-collector paths of input and output transistors
Inventor: MAYER HARTMUT
IPC: F02P3/04
Filed: 1976-10-29
Abstract: The ignition system contains a threshold switch which has an input transistor, connected to the signal generator, with a normally conducting emitter-collector path. The switch contains an output transistor whose emitter-collector path is normally non-conductive. A final stage transistor emitter-collector path serves for interruption of d.c. flowing through the ignition coil primary. A control capacitor stores an energy inversely proportional to the engine speed, as in 2244781. An additional capacitor can have its charge conditions changed via the conductive emitter-collector path of the output transistor in one current flow direction, and over the conductive emitter-collector path of the input transistor in the other current flow direction. The conductive of the emitter-collector path of the final stage transistor takes place prior to attainment of a given charge voltage value at the second charge condition change.

Title: Melting silicate glass with high furnace loading - using methane fuel contg. oxygen to reduce flue gas vol. and noise
IPC: C03B5/14
Filed: 1976-12-27
Abstract: Silicate melts are made by firing a rotary kiln with a mixt. of fuel (methane) and O2 in the ratio 1:1.7. The ratio of fuel/O2 mixt to melt is 0, 6 to 1:1. Air, water, soot particles may be added to the fuel-O2 mixt. The flame profile can be modified in the usual ways. The furnace loading may be increased to 34 to 40 vol.% (36-38 vol.%). The use of O2 as oxidant in the furnace reduces the vol. of the flue gases, and the noise evolved. The flame temp. is higher and fuel consumption is lower. The lower gas velocity means that less of the components of the glass or glass fibres and droplets are blown out of the end of the furnace. Less maintenance is required. The flame profile may be controlled much more easily. Waste heat can be recovered in a recuperator. There is less pollution.

Title: Turbulence chamber valve with no moving parts - has outlet orifice with adjoining tapered shell and control jet entering tangentially into chamber
Inventor: BROMBACH HANSJOERG DR ING
IPC: E03F5/10
Filed: 1977-03-22
Abstract: The turbulence chamber valve chamber has a supply jet (9) through which the fluid is ducted during the open condition of the valve. The fluid flows along the bottom chamber walls in the region of the lowest surface lines (6, 7) and reaches in a straight path the outlet orifice (4), which deflects the flow by 45 degrees downwards and then into the outlet orifice. If a second flow is introduced through a control jet (10) in a tangential direction, the two flows meet immediately after the apertures. The united flow then travels along a three-dimensional spiral path. The high centrifugal forces in the region of the outlet cause a flow resistance to the supply.

Title: Forging hot metal powder in single operation - to form finished article, using shaped, readily deformable container
Inventor: BUCHOVECKY KALMAN EDWARD
IPC: B22F3/12
Filed: 1977-11-01
Abstract: Aluminium metal powder is forged in a readily deformable metal container having a general shape of the article to be formed. The powder is heated to >=600 degrees F to facilitate metallurgical bonding of the powder during the plastic deformation. A cover is placed over the open end of the container so as to contain the powder and permit escape of gases evolved from the heating of the powder. The container and powder are fored to a density of >=99% by compressing between dies having provision for escape of excess metal. Method is for cladding of powder forged articles and prodn. of composite articles from multiple powder alloys. The provision of the cover permits the powder to evolve its own protective atmosphere during preheat while allowing some gases to escape. The requirement of complex multi-action tools and intricately shaped containers is eliminated and the finished products have improved mechanical properties of conventionally forged powder metal parts.
