Title: Shut-off device for pipelines - using dip pipe in liq. which is frozen or melted by external medium
Inventor: REITZENSTEIN HERMANN DIPL ING
IPC: F16K13/10
Filed: 1975-06-05
Abstract: Shut-off device for flowing materials, consists of an enclosed container with inlet and outlet pipes above the liq. level, one being attached to a dip pipe which has a surrounding jacket in the dip region, and contains a liq.-displacing body, the vertical position of which can be varied. The jacket has inlet and outlet pipes for circulation of a cooling or heating medium. Used in pipelines contg. materials which condense out and solidify or crystallise, e.g. heavy distn. residues, pitch and S-contg. vacuum residues, in dewaxing and deasphalting processes, gas desulphurising, etc. The device contains only one moving part, the relative position of which is not critical and which does not require to be a close fit in the dip pipe, so that wear, blockage of guides, etc. are eliminated. Shut-off is achieved by freezing of liq. in the gap between the body and dip pipe, so that wear, corrosion, erosion, etc. cannot cause leakage or contamination of food products.

Title: Undercutter for tubular wall plug - has bush and off centre cutter shaft rotated in hole
Inventor: LIEBIG HEINRICH
IPC: F16B13/06
Filed: 1975-08-06
Abstract: The rotating cutter (22) is used to produce an undercut groove in a location hole in masonry or similar low density material.

Title: Probe-type spray nozzle assembly - is surrounded by elastic guard for keeping orifice away from walls of hollows and other restricted areas
Inventor: RICHTER HEINZ
IPC: B08B3/02
Filed: 1976-08-20
Abstract: The spray nozzle serves for applying paints, cleaning agents, or protective coatings on inside walls of hollow spaces, such as insides of tubes. The probe-type nozzle (6) is surrounded by an elastic guard consisting of several spring wires (5) of elliptical shape and arranged in equal distances around the probe (6). One end of each wire is fixed rigidly to a hub-like part (7) fitted on the orifice end (2) of the spray nozzle. The other ends of the wires are similarly fixed into a hub (8), but this hub is slidably mounted on the probe surface. When introducing the probe through an access opening (14), which may be considerably smaller than the inner diameter of the hollow to be treated, the elastic guard is compressed to the diameter of the access opening while the hub (8) performs a sliding movement on the probe surface. Once the probe is inside the hollow, the guard returns to its original shape and keep the orifice (2) out of contact with the surrounding walls.
