Patent DE-2005869-A1 (DE)
Title: Gas purification by contraflow with particles
IPC: B01D46/32
Filed: 1970-02-10
Abstract: Particles receiving hot gas are stacked in a heat exchange bed above a perforated floor. Particles can trickle slowly through floor, and fall onto an inclined wall of louvres, through which the gas enters horizontally before turning upwards to enter heat exchange bed. The particles, temporarily trapped in the louvres, constitute a filter bed, those which pick-up impurities being segregated, when the escape from the lower end of the inclined louvred wall, into a separate circuit containing a separator.

Title: Hydraulic tie bar extension for rolling mill stand
IPC: B21B13/14
Filed: 1970-03-13
Abstract: Device for effecting the hydraulic extension of a hollow tie bar of a pretensioned rolling mill stand, independently of the clamping nut, uses a tie bar with a pot shaped gripping head consisting of a hydraulic tensioning device with the tensioning force acting on the front face of a core pin mounted in a blind axial hole of the tie bar and supported by the bottom of this hole. The front face of this core pin is exposed, so that the cylinder of the hydraulic device can be easily connected to and disconnected from the tension rod. The connection has to be able to withstand tension. A separate tensioning device is used for each tie rod of the mill stand. This is a quick and cheap way of tensioning tierods.

Title: Relay spring contacts or pole laminations adjuster - has clamping device and driven bending lever providing increasing bending strokes
Inventor: HOCK LOTHAR
IPC: H01H49/00
Filed: 1974-02-27
Abstract: The adjusting device is intended for aligning of strip sheets, such as pole laminations a contact springs of relays. It has a clamping device in which the strips are held in a defined position in relation to a position scanner and to a bending lever.
