Title: Atomisation of liquids using gas - or dispersal of gas as small bubbles in liq.
Inventor: CHAWLA JOGINDAR MOHAN DR ING
IPC: B05B17/04
Filed: 1976-06-22
Abstract: In a process for atomising liqs. using gases or vapour, or for dispersing a gas as small bubbles using a liq., whereby the two phases are mixed, the velocity of the two phase mixt. at the outlet form the mixing chamber is arranged to be equal to the characteristic sonic velocity for the mixt. This is achieved by appropriate selection of the approach velocities of the separate phases w.r.t. the relevant values of their properties (e.g. temp., press.) and to the cross-sectional area of the mixing chamber. The mixt. experiences a sudden fall in press. on leaving the mixing chamber. Used in e.g. drying, combustion and incineration processes, etc. Atomisation processes relying on shearing of the liq. by a gas require upto 1000 litres of gas per kg of liq. The present process can require as little as 10 litres per kg.

Title: Object guarding alarm circuit - triggers warning signal through changes in sensing coil inductivity due to geometry variation
Inventor: WINKLER HANS-GEORG ING GRAD
IPC: G08B13/26
Filed: 1976-07-08
Abstract: The alarm circuit guarding an object is triggered when the latter is moved and causes changes in the geometry of the sensing loop which leads to alteration of resonance frequency in the oscillator. The sensing loop does not respond to the presence of persons, and thus leaves a free access for the examination of the object, such as a valuable carpet. Life of the carpet or its rolling up leads to changes in the geometry of the sensing loop attached to it and this trips the alarm. Transformer (2) matches the inductivity of the sensing loop (1) for the tank circuit (3) of the oscillator (4) whose frequency changes are detected by a discriminator (5). Changes in the voltage of this are transmitted to a differentiator followed by amplifier and alarm relays.

Title: Air and fuel preheater for blast furnace gas burner - heats fuel with preheated air from heat exchanger in flue gas pipe
IPC: F23L15/00
Filed: 1977-05-18
Abstract: The flue gases are used to pre-heat more air than the combustion requires. The excess is diverted to pre-heat the fuel gas. Thus the fuel gas is kept well away from the flue gas. If corrosion of the heat exchanger leads to a fuel gas leak, the escape is easier to detect in a fuel-air mixture than in a fuel-smoke mixture. The air which pre-heats the fuel gas may be re-cycled. The combustion chamber (1) of an installation heated by weak gas, e.g. steam boiler or a gas and air heater is fed with the gas, pref. exit gas, through pipe (2) and combustion air through pipe (3). A heat-exchanger (5) is provided in the flue gas pipe (4).

Title: Current monitoring threshold switch - induces pick=up coil pulse when polarised wire field is reversed by measurement current field
Inventor: WEISS KARL-ERNST
IPC: G01R19/165
Filed: 1978-06-02
Abstract: A threshold switch for monitoring currents produces an electrical output signal when the monitored current exceeds a given threshold value. It consumes minimal power, is relatively simple and economical to make, and extremely insensitive to noise. The signal is generated using a wire (12) and associated pick-up coil (13). The current passes through a measurement coil (14) wound round them. The wire (12) is associated with a reset device which returns it to its original state of magnetic polarisation. When the magnetic field induced by the current overcomes the wire polarisation a pulse is induced in the pick-up coil.
