Title: Anti frost burner device - has reduction gear, fan, pump, roller, nozzle and sleeve
IPC: A01G13/06
Filed: 1974-06-21
Abstract: An anti-frost device has a platform which pivots on a wheeled frame (1) around a vertical axis or rollers running on a track. An engine drives a reduction gear through a transmission. A roller is keyed to an output shaft from reduction gear. A fan fixed to engine shaft also drives a fuel pump connected to a feed pipe and fuel injector at the start of a burner nozzle connected to a sleeve by radial strips. Where the nozzle protrudes beyond the sleeve, it is perforated by elongated apertures. In operation the engine causes the platform to rotate, at the same time driving the fan which blows air into the sleeve. The air is guided by vanes, and one part passes through the burner nozzle and is burnt with the fuel. A small amount of air passes through the burner nozzle and is burnt with the fuel. A small amount of air passes through the apertures so that the air pressure at the nozzle outlet equals that inside the nozzle, avoiding flashback. The tepid air produced prevents the formation of frost.
Patent FR-2234914-A1 (FR)
Title: Throughflow cyclone separator - with tangential auxiliary fluid inlets given extra inclination
IPC: B04C3/06
Filed: 1974-06-26
Abstract: Auxiliary fluid inlets, disposed on a helix around the cylindrical body of a cyclone, with axial main inlet and outlet, are angled, e.g. at 30 degrees to the line of the helix, towards the main inlet so that the displacement of auxiliary gas flow towards the outlet is reduced. In this way input of auxiliary fluid may be reduced up to 20% and necessary pressure also cut. Entrained particles in the main flow, which is rendered helical by main inlet vanes, are thrown out centrifugally into auxiliary flow, and expelled via an annular orifice around the main inlet. Residence time of particles in cyclone is shorter, thus abrasion is alleviated.

Title: Beam-guidance in electron beam welding - avoiding phase-displacement between the deflection current and resultant magnetic flux
Inventor: SHAPOVAL V I
IPC: B23K15/02
Filed: 1975-02-06
Abstract: Process for guiding the electron beam onto the joint between two parts being welded, where the current (I) in the deflection system is sinusoidal; the beam is moved like a pendulum over the joint; and the sec. emission signal is displayed on a cathode-ray tube, with time-base proportional to current (I), and used to displace the beam w.r.t. the joint. The novelty is that the signal is deflected on the screen of the cathode ray tube w.r.t. time so the amplitude of the time-base voltage or current is proportional to current (I), and in the region of max. current a phase reversal occurs for the voltage or current; and the two displays of the signal thus obtd. are merged by moving the beam w.r.t. the joint. The pref. device is included in the claims. The phase-displacement between current (I) and the magnetic deflection flux does not influence the guiding of the beam.
