Title: Cleaning flue gases from incinerators for chemical wastes - by absorbing acid cpds into particles which are continuously introduced-removed (NL110576)
Inventor: STEENSMA METSKE
IPC: F23J15/02
Filed: 1975-11-03
Abstract: In a process for removing acidic constituents from flue gases arising from incineration of chemical wastes the flue gases are first cooled to a suitable temp. and then passed through a bed of particulate solid material which absorbs the acidic constituents by reacting with them. The solid particles are continuously introduced into one side of the bed and move through it to the other side, from which they are removed. The gases flow countercurrently through the bed with respect to the particles. The flue gas temp. need only be reduced to a value at which the absorption reactions proceed quickly. The flue gases are not saturated with water vapour by the cooling process. The bedis not fluidised and the problems associated with fluidised beds (e.g. attrition leading to dust entrainment in the gas) are eliminated.

Title: Monitoring changing parameters in inaccessible environments - e.g., corrosion in reactors, by detecting change in resonant frequency of vibrating probe
Inventor: HANCOCK PETER
IPC: G01N29/036
Filed: 1976-07-20
Abstract: A probe is caused to vibrate from an external energy source, and its resonant frequency monitored. Changes in environmental parameters cause a change in the resonant frequency and can thereby be detected and monitored. A probe may take the form of a strip or bar or circular section, and may, e.g. be made of the material whose corrosion rate is to be monitored. The probe is vibrated at a frequency of 0.3-3.0 Hz by an externally mounted electrically driven energy source, connected to the probe by a rigid coupling. Used for on-line monitoring of corrosion or solids deposition within chemical reactors or equipment such as turbines or compressors and for the detection of ice formation outside buildings or on aircraft wings. Monitoring in inaccessible situations is readily possible so that expensive plant shut-downs for internal inspection are minimised.

Title: Four-stroke combustion engine with intake air feed - has fuel feed system which introduces fuel into air passed through intake
Inventor: DALY PAUL DESMOND
IPC: F02B75/02
Filed: 1976-09-15
Abstract: Four stroke combustion engine when an intake system feeds air through an inlet valve into each engine cylinder during the inlet stroke of the engine cycle. A fuel feed system introduces fuel into the air passed through the intake system while a throttle valve regulates the fluid flow in the intake system. Specifically a controller (23) acts to interrupt the periodic introduction of fuel through the fuel feed system (22) into the intake air with a simultaneous adjustment of the throttle valve (21) giving a min. flow obstruction in the intake system (20). This interruption ensures that the ratio of the fuel added air charges to the total number of all intake air charges for a given number of operating cycles of the engine is less than one.
