Patent DE-2904855-A1 (DE)
Title: Hot cupola gas burner with self-igniting pilot flame - which uses carbon mon:oxide drawn off from high temp. region of cupola
Inventor: KAISER FRANCIS T
IPC: F27B1/08
Filed: 1979-02-09
Abstract: A cupola includes a take-off port through the walls positioned above the tuyeres in the reducing zone space for bleeding off a portion of the hot gases. A conduit communicates the post with a pilot burner positioned adjacent a charge opening of the cupola. The hot gases are at temp. above the self-ignition temp. of CO when mixed with air. A combustion-supporting gas is injected into the burner to cause self-ignition and burning of the CO present in the hot gases withdrawn from the cupola and provide a flame adjacent the charge opening. A self-igniting pilot flame is provided which does not require an external supply of natural gas. The take-off port is water cooled so that particles of ash entrained in the hot gases do not stick to the walls of the port. The conduit is near vertical so that particulate solids in the gas stream fall under gravity back into the cupola.

Title: Oil water separator - using tank with water and oil over flows at different levels separated by partition
Inventor: BAER ALFONS
IPC: B01D17/025
Filed: 1979-03-16
Abstract: A device to separate an oil-water mixt. uses a pump to circulate the fluid between the water reservoir with the mixt. and a separator tank. The latter has two overflows at different levels, sepd. by a partition with an opening at the bottom. The higher overflow is used to pass the floating oil in a receiver which is drained at regular intervals or automatically. Such a plant separates continuously oil from water within a separator tank in the suction line.

Title: One-piece loudspeaker housing - made from casting resin made of polyester with sand filler
IPC: H04R1/02
Filed: 1979-04-03
Abstract: A loudspeaker housing is made in one piece by a casting technique, using a mixt. of non-shrinking polyester resin with sand. The pref. mixing ratio is 10-30 vol.% (20 vol.%) polyester to 70-90 vol.% (80 vol.%) sand. The pref. wall thickness is over 10mm (40mm.) and all necessary holes are cast in so that no machining is required. To add an outside fine layer of coloured polyester, this layer is applied to the mould walls before the resin is poured. Such a housing can be produced at much lower cost, because sand is much cheaper than polyester, yet it meets all requirements.
Patent DE-2919755-A1 (DE)
Inventor: JENSEN HARALD DR
IPC: C07C231/00
Filed: 1979-05-16
Abstract: N-Vinyl-N-alkyl-carboxylic acid amides are prepared, starting from N-ethyl-carboxylic acid amides, in a 3-stage process consisting of the following stages: (a) anodic alkoxylation of the N-ethyl-carboxylic acid amides to give N- alpha -alkoxyethyl-carboxylic acid amides; (b) alkylation of these N- alpha -alkoxyethyl-carboxylic acid amides with an alkyl halide or dialkyl sulfate in an alkaline medium to give N- alpha -alkoxyethyl-N-alkyl-carboxylic acid amides; and (c) splitting off of alcohol from the products of stage (b) by heating to temperatures between about 60 DEG  and about 350 DEG  C. Instead of stages (b) and (c), it is also possible to carry out the following stages after stage (a): (b1) splitting off of alcohol from the N- alpha -alkoxyethylcarboxylic acid amides obtained in stage (a) by heating to temperatures of about 60 DEG  to about 600 DEG  C., to give N-vinyl-carboxylic acid amides; and (c1) alkylation of these N-vinyl-carboxylic acid amides by reaction with an alkylating agent of the same type as in stage (b) in an alkaline medium. The N-vinyl-N-alkyl-carboxylic acid amides obtained by the process are valuable intermediate products, in particular for the manufacture of homopolymers and copolymers with interesting properties.

Title: Automatic bulk agricultural material weighing machine - avoids clogging by using three chamber weighing drum receiving material directly
Inventor: BUSSMANN KARL HEINZ
IPC: G01G13/24
Filed: 1980-02-01
Abstract: An automatic balance for weighing bulk material is esp. suitable for agricultured applications and the weighing of feedstuff such as silage and additives. It eliminates the clogging which rapidly occurs in conventional balances leading to increasing errors until the machine becomes completely blocked. This is achieved whilst retaining the same approximate dimensions. The weighing machine contains three or more chambers rotating about a common central axis. The weighing drum is stopped during its rotation about the central axis for each chamber. The goods pass directly into the chambers from a tube or rack. The 'fill weight' is adjustable by means of a rocker on one end of the drum and a counterweight on the other which can be slid as required.
