Title: Fireplace waste air mixing hood - has internal shallow funnel within truncated conical hood for mixing
IPC: F23L17/14
Filed: 1976-02-25
Abstract: Waste air mixing hood for a fireplace, in which the waste air flows upwards around an upwards expanding funnel. The waste air is mixed efficiently with fresh air within the hood. The concentration of toxic substances is greatly reduced when the gases emerge from the hood. A radial space is formed between the chimney channel and hood. Between the chimney (2) and hood (6) is left a radial gap (a). This hood arrows gradually upwards to form a truncated cone or pyramid. The hood base has constant cross section up to a certain height. Into this hood is placed centrally funnel (10) with narrow point facing downwards. Any residues are removed from funnel by drain (11).

Title: Filamentary breakage detection - by registering their diffraction spectra derived from electromagnetic short wave oscillations with lasers
Inventor: HAUSER GUENTHER DR ING
IPC: G01N15/02
Filed: 1976-08-18
Abstract: Small objects are measured with the aid of electro-magnetic short wave oscillations by registering their diffraction spectra with e.g. laser transmitters. Pref. part of the receiver is covered to an extent necessary to prevent registration of very short oscillations. Also the size of the cover can be selected such that deflections of the beam produced by the vibration of the transmitter are not registered. By polarisation of the oscillations and selective application of screens the filaments can be sorted out w.r.t. direction of movement. Also the beam can be split into a number of subsidiary streams which can be directed to different indicating instruments. Used for monitoring breakages of metallic, synthetic, glass or textile filaments. Tripping or braking machines, operating counters, pen recorders or alarms. Filaments in the most inaccessible spaces can be readily monitored.
