Title: Paper slurry mixer - with stator and rotor passages assisting unobstructed flow
IPC: D21B1/06
Filed: 1969-09-06
Abstract: A machine for breaking down, mixing, emulsifying, homogenising, dispersing and/or gassing organic and inorganic materials, e.g. paper slurries, comprising radially alternating stators and rotors has the stator passages formed so that they taper in the flow direction, with the smaller, outer end of each duct directed against the rotational direction of the roter. Specifically, the outlet ends of the stator ducts form a sharp angle with the walls of the rotor stage. The wide, inner ends of each stator duct extend over a number of duct widths of the inner rotor. The arrangement reduces power consumption, leads to high operating speed and, avoids interruption to the flow due to recycling.

Title: Load distribution system for LV mains supplies - has normal limiter and AF controlled special limiter between load and supply
Inventor: FEINDT HEINRICH
IPC: H02J13/00
Filed: 1974-01-30
Abstract: The load distribution system, for low voltage mains supplies has each load coupled over two limiters to the main supply. In normal operating conditions the second limiter, i.e. the one closest to the load, is short circuited and only the first limiter transmits the power to the load. The second limiter is controlled by an audio frequency receiver that is supplied with its own control signals via the low voltage mains supply. When the mains power available becomes more restricted, the second limiter is switched in to reduce the load consumption. The two separate limiters may be combined into one limiter assembly having two settings.
