Title: Heating fluidised bed - using spray of high boiling oil directly mixed with air or oxygen
Inventor: RENNHACK ROLF DR ING
IPC: F23C10/22
Filed: 1971-11-23
Abstract: An appratus for directly heating fluidised bed reactors using liquid fuels, esp. oils having a high boiling pt. comprises two concentric feed ducts one for fuel, one for oxygen-contg. gas; these both discharge into the fluidised bed, and are supplied from fuel and oxygen-containing gas headers below the fluidised bed ggrating.

Title: Revolvable latch for vehicle door lock - main actuating lever has control for intermed iate lever and latch
Inventor: SCHUETZ JOACHIM
IPC: E05C3/24
Filed: 1973-08-23
Abstract: The lock is suitable for a sliding door, which is moved from a locking plane into a sliding plane. The lock has a revolvable latch, which acts together with a locking pin, and is connected to a locking element. The locking element engages with a swivelling intermediate lever, to move it into a position, where it is locked, by the engagement of a main actuating lever, when the latch swivels into the locking position. The main lever is connected to a power transmission element, which with the actuating of the lock, moves it from the engaged position, into a position, allowing the movement of the latch into an open position. The main lever has a control for the intermediate lever and the latch. The control only becomes active, after the main lever has been moved out of its engaged position. The outer flank of the latch supports itself on the locking pin to reinforce the movement of the door into the displacement plane.
