IPC: B01F11/00
Filed: 1975-02-18
Abstract: Emulsifier consists of three cells suspended from a plate mounted on springs on a beam to which is attached a vibrator. Between the cells are screens above which are movable plates which allow liquid to pass upwards. The vibrator operates at a frequency of 10-200 Hz in the sonic range with an amplitude of 0.1 to 9 mm. The liquid is at the bottom and the product leaves at the top. The effect is improved by filling the cells with balls. Used esp. for making stable oil/water emulsions. The use of sonic and ultra-sonic vibrations is known from vibration has the advantage of producing a finely dispersed emulsion. However equipment has tended to be complicated, requiring very high investment costs. Often they have low throughput with very high energy consumption. The process described avoids these problems. The vibration causes the oil to be subject to alternating energy impulses which break droplets down and spread them evenly through the system.

Title: Loss-free connection of high voltage cables - uses oil based grease to fill voids between cover layers
IPC: H02G15/068
Filed: 1976-05-20
Abstract: The method is for connecting cables or cables to equipment where the voltage may exceed 1KV. The method is intended to prevent the formation of voids between semiconducting and insulating layers when a discontinuity occurs as in a cable junction and the consequent ionization of a trapped gas and breakdown of the cable. The cable sheathing (4) when cut at such a junction forms a step, the void (8) appearing in a triangular cross-section annulus between the insulation and the heat-shrunk outer sleeving (5). The technique specifies the filling of this void with an oil based grease. The grease should be able to 'wet' the surfaces concerned and have a viscosity between 40 and 130 Po and have a resistivity of about 108 OHM/CM. The surface tension should be between 10 and 35 dynes/cm.
