Title: Improved flow distribution in fluidised bed reactors - using vertical stand pipes in bed with gas outlets at several levels above bed support base
Inventor: MOLERUS OTTO PROF DR ING
IPC: B01J8/18
Filed: 1978-09-13
Abstract: Fluidised bed reactor has a gas stream which is being reacted in the presence of a suspended particulate catalyst or other reacting solids. Gas is injected into the bed at more than one level. At the lowest level, where the bed is supported, the gas enters as a vertical stream. The bed has stand-pipes in it with outlets at one or more other levels from which the gas issues as a horizontal stream. The gas is injected into the bed continuously from these points. Use for gas/solid reactions e.g. catalytic methanisation of coal gasification product gases. Allows for a much more uniform distribution of gas through the bed which gives more uniform reaction and heat release, avoiding local overheating at the point of entry for the gases.

Title: Mounting for relay contact spring sets - has narrowed connection tail and recesses either side for support pins
Inventor: ENGE HORST
IPC: H01H50/56
Filed: 1979-01-05
Abstract: Spring contact sets for a relay are mounted in the wall or mounting block of the unit. The spring sets are made with a reduced width tail so that they enter and are supported by the block as full width springs but a long narrow tail protrudes from the other side of the block for circuit wiring. The object is to avoid a welded or crimped connection between spring and terminal in the vicinity of the spring set mounting block. The springs (6, 7) enter the mounting block (1) at full width but are reduced in width (5) after the longitudinal support pin (14) to form the wiring tail (8). Each spring has a semicircular recess on each side, one above the other, into which a support pin (14) fits on either side of the mounting block (1) into a preformed recess (13). This support method holds the springs rigid through the block (1).
