Patent ES-405552-A1 (ES)
Title: Infrared absorption analysis method and apparatus for determining gas concentration
IPC: G01N21/35
Filed: 1972-08-04
Abstract: There is disclosed a dual beam gas analyzer and the mode of operation thereof for measuring small concentrations of a gas of interest in the presence of another gas having absorption bands overlapping those of the gas of interest. This is encountered in the determination of the concentration of CO2, CO, CH4, C2H2, NH3 or SO2 in the presence of CH4, CO2, CO2, CO2 or CH4 respectively. The dual beam gas analyzer comprises a source of infrared rays providing an infrared beam which is directed into one end of an analysis chamber through an optical commutator. The optical commutator directs alternately and periodically the infrared beam to a comparison filter transparent to the infrared beam and to a gaseous filter absorbing completely the energies of the absorption bands of the gas to be measured. The output signals of a non-selective radiation detector disposed at the other end of the analysis chamber are applied to electronic circuits which provide a signal representative of the difference between the energies of the two successive beams passing through the analysis chamber. A movable shutter permits one to modify the energy of the beam corresponding to the comparison filter and is adjusted to eliminate the influence of the other gas on the determination of the concentration of the gas of interest. According to one embodiment an auxiliary tube is placed along the path of the beam passing through the gaseous filter to increase the precision of the gas analyzer in cases where the concentrations to be measured are in the range of a few tens ppm.

Title: Improvements introduced to whey removing and cheese guillotine machines.
IPC: A01J/
Filed: 1979-01-25
Abstract: A machine equipped with the improvements submitted in this invention and whose purpose is to remove the water or whey from the milk, press the paste obtained and to cut it automatically into pieces in accordance with predetermined measurements, for the pieces to then be passed to the curing moulds. The raw material is received through a channel and then is stored on perforated trays which allow the whey to pass from the curd and retain the paste or solid part of this raw material. Sensors will be fitted to determine when the ideal amount of curd has been obtained to proceed to the cutting process, moving it by means of a carrier plate to a press which, once completing its compression, allows the product to be fed into a guillotine which cuts the paste into pieces in accordance with previously established dimensions. Establishing the suitable measurement is the main object of these improvements and is carried out by means of a cutter which is adjustable in length and made of Teflon or a similar insulating, non-hygroscopic and machinable material, which has been fitted with a sensor called "maximum measurement", which on noting the presence of the paste or wet cheese, emits an electrical signal which duly amplified will send the relevant instructions for the automatic operation of the system. It is also important to mention the presence of a "safety grid" consisting of a stainless steel louvre panel placed in a pivoting position over a main cutter which is insulated by mechanised Teflon caps.
