Title: Electronic filter for generating a third harmonic signal
IPC: H04N9/44
Filed: 1981-04-30
Abstract: An integratable third harmonic signal generator comprises an amplitude limiting amplifier, a linear amplifier, and a signal combining network. A sinusoidal input signal is coupled to the limiter and linear amplifiers. The limiting amplifier generates a square wave signal containing a first harmonic (fundamental) component at the frequency of the input signal, and higher order odd harmonics including a desired third harmonic frequency. The signal gain of the linear amplifier is set so that the magnitude of the output signal from the linear amplifier is sufficient to cancel with the first harmonic of the square wave output signal from the limiter amplifier, when these output signals are combined in the combining network. A resulting signal developed at the output of the combining network contains the desired third harmonic component, as well as higher order harmonics at acceptably reduced levels relative to the third harmonic component, to the substantial exclusion of the first harmonic component.

Title: Method and apparatus for immunoassays.
IPC: C12M1/00
Filed: 1986-07-01
Abstract: An apparatus and process for conducting ligand receptor assays. The apparatus comprises a first member which is a membrane or a filter (20) to which is bound a receptor for the ligand or which is capable of extracting cells carrying the ligand from a fluid sample. The apparatus further comprises a second member which is composed of absorbent material (22) which acts when in contact with the first member to induce flow through the first member (20) when a fluid sample is added to it. The apparatus is used to conduct assays by applying a sample to the upper surface of the first member (20) to bind ligand in the sample by means of receptor fixed to the first member or, in certain cases, by extracting cellular material which has ligand associated with it. Addition of the sample is typically followed by addition of labeled antibody against the antigen being assayed followed by a washing step to remove unbound labeled receptor. The presence of labeled antibody on the first member after washing is indicative of the presence of the antigen in the sample being assayed. In a preferred embodiment of the invention, the ligand is an antigen and the receptor is an antibody.

IPC: B01J8/24
Filed: 1986-07-15
Abstract: An installation for producing cement clinker which includes mixing the raw materials forming the cement with water, coal or coke and cement as a binder and converting this mixture of materials into nodules by granulation or extrusion is described. The system is particularly designed for use in the manufacture of white cement where raw materials with a low content of colouring compound are used as a primary feed. The nodules are then dimensioned to obtain a feed material which has a particle size range of the order of 6.35 mm for 14 mesh which is suitable for use in a fluidised-bed reactor. The nodular raw material is heat-treated in a fluidised-bed reactor at temperatures within the range of approximately 137 degree C to 148 degree C for white cement and 128 degree C to 134 degree C for typical grey Portland cement. The carbon in the coal or coke mixed with the raw material provides between 60 and 90% of the fuel required for the process, the rest being supplied directly to the fluidised bed. This fuel is used to provide internal reducing conditions within the particles of material. The product is discharged from the fluidised bed and cooled in an indirect heat exchanger.
