Title: Wind driven flue draught inducer - has wind powered wheel of smaller diameter than draught fan wheel
Inventor: KEIDERLING GEORG
IPC: F23L17/10
Filed: 1973-12-21
Abstract: The draught inducer has a casing which fits on top of the flue. It has an upper cowl with vertical inlets to direct wind over the driving impeller.

Title: Flight landing system helicopters - employs electromagnetic signals on the landing stage to assess the craft height
Inventor: WEISSER WERNER
IPC: G05D1/06
Filed: 1974-09-27
Abstract: The landing approach system for an aircraft is in particular for a helicopter, in which assessments are made in the craft of signals emitted from the landing location. The angle between two beamed lobes relevant and also the heaviness of directional ariels on the underside of the craft. Restriction on the frequency band used is disadvantageous. Use is made of two spaced apart points on the landing location which emit synchronised signals. The craft altitude is limited so that the received signals have a constant difference in period of duration. The signal emitting points can be constituted by two sets of pairs of points. A helicopter (6) required to land on a location (7) is guided there by pair of signal points (2, 3) complemented by pair of points (1, 4) on the desired line of approach.

Title: Radio chemical wood processing - by impregnating with vinyl monomer and irradiating with gamma rays
Inventor: JANKOWSKIJ BORIS A
IPC: B27K3/15
Filed: 1975-03-14
Abstract: In processing wood by impregnation with vinyl monomer followed by irradiation with gamma-radiation of Co-60 to polymerise the monomer, the wood is also irradiated before impregnation with monomers at an integral dose of 2-100 Mrad and the irradiation after impregnation is effected at an integral dose of 1 to 30 Mrad, according to the monomer used. Pref. the pre-impregnation irradiation is effected wity gamma-radiation of 2 to 25 rad/S, and is carried out in a medium of inert gas, e.G. argon or nitrogen. The pre-irradiation creates a "soft" ageing of the wood similar to the natural ageing process and creates suitable conditions for grafting the monomer on the wood so as to increase dimensional stability. The wood-plastic prod. is esp. useful for musical instruments.
