Title: Improved efficiency in liquid mixture separators - by prior removal of solids and gas bubbles in the feed stream
Inventor: GIBSON ROLAND RICHARD
IPC: B01D19/00
Filed: 1973-08-07
Abstract: The efficiency of liquid/liquid mixture separators, partic. centrifugal separators, is improved by prior removal of gas specif. air, bubbles and solid particles in a pre-separator. This uses a pressure soruce to drive it and induce a flow of contaminated mixture in the line. This is followed by filter elements to remove solids and then by baffles to disentrain gas or air bubbles. This is of partic. application on cooling water circuits for marine diesel engines where oil entrainment is a problem.

Title: Printed circuit unsoldering tool - combines light radiator and reflector with suction device
Inventor: AUST GERD-RUEDIGER DIPL ING
IPC: B23K1/005
Filed: 1974-03-18
Abstract: An unsoldering tool for modules in printed circuit boards uses a focussed light radiator (either a point source or a strip source) to heat the solder to the fusion point. A suction device with intake openings to suit the unsoldered area is used to remove the solder from the joint. This concentrates the heat better where it is wanted than when a manual soldering bit is used. No remnants of solder are left and the surrounding modules are not heated. The device is not expensive znd is suitable for any size of batch.
