Title: Automatic downward vertical electric fillet welding - forming single pass welds using three burners and carbon dioxide protective gas
Inventor: IIZUKA SHINPEI
IPC: B23K9/025
Filed: 1973-03-27
Abstract: Downward fillet welding of two plates forms L or T joints, etc., where several spaced burners travel simultaneously along the joint at constant speed. A vertically-mounted hydraulic chamber has a horizontal table fitted to the ram so that the table can descend at constant speed. Three horizontal burners pointing slightly upwards are mounted on the table in a vertical row, the distance between each being 40 mm. The lowest burner points towards the joint-line while the others are slightly off-set to each side. Three welding sets, each of 300 A, supply power to each burner which is fed continuously with welding wire. The lowest burner provides the first deposit and heats the joint so that the two following deposits combine and no cold spots occur. The max. welding length is 1.4 m and the downward travel can vary from 10-50 cm/minute. A pair of guide-rollers run on each of the plates being welded, and the unit is fitted with limit switches and controls. Carbon dioxide gas is used in the conventional way. Fillet welds can be laid at e.g. 30 cm/minute.

Title: Nonstick agent-lubricant for metal forming - with water-insoluble nonemulsifiable substances in microcapsules
Inventor: UMHOEFER ERNST
IPC: C10M169/00
Filed: 1973-09-11
Abstract: The Parent Patent No. 2238604 described a non-stick agent and lubricant for metal-forming operations which is used in the form of microcapsules. In the addition the agent or lubricant consists of substances which are insoluble in water and are neither emulsified nor dispersed. They are applied in an aqueous suspension. This removes the restriction which limits the solvents to hydrocarbons such as benzene etc. Good heat dissipation is achieved by adding pigments to the agent or lubricant. The lubricants which are soluble only in organic solvents are microencapsulated and are applied as such or as an aqueous suspension. If they contain pigments, there is no risk of the different specific gravities leading to differential precipitation of these components during storage.

Title: Extinguishing fire of combustible liquid - with porous, noncombustible substance saturated with fire-extinguishing liquid
Inventor: SEIDL ALOIS
IPC: A62D1/00
Filed: 1973-10-25
Abstract: A combustible liquid fire, e.g. of petrol or an oil, is extinguished by means of a lightweight, porous, granular, non-combustible substance saturated with a fire-extinguishing liquid, such as water or an inorganic soln. The bulk density of the saturated substance should not exceed 0.7 g./cm3.; the grain size is pref. 0.2-20 mm. (esp. 1-10 mm.; with the proviso that the content of particles below 0.2 mm. does not exceed 5 wt. %), and the absorption capacity is 5-1200 wt. %. Fire-extinguishing effect is due to the cooling by the liquid contained in the porous substance, esp. when the liquid evaporates and heat is absorbed from the surroundings; and also to the air access-blocking effect exerted by a layer of the lightweight substance sloating on the burning liquid. In some cases, the porous substance can be recovered after having extinguished the fire.

Title: Refuse incinerator with gasifier and burner - prevents oxidation of metallic refuse and uses afterburner heat for oxidation
Inventor: HAZZARD NOEL DAVID
IPC: F23G5/027
Filed: 1973-11-10
Abstract: Incomplete combustion takes place in the first combustion chamber of the incinerator and gas is produced from the organic refuse. The second combustion chamber used as afterburner is used for complete combustion of the gases generated. Heat generated in this second chamber is used for gasification of refuse in the first chamber. This arrangement ensures that the metallic components in the refuse in the first chamber are not oxidised, and also prevents contamination of the atm. air by inorganic components such as metal oxides and facilitates recovery of the metals. The incinerating system has a first combustion chamber into which shredded refuse is fed by a screw. The refuse comes into contact with the cylindrical combustion chamber walls which are heated by the heat generated in the combustion chamber. The solid residue from the first chamber is returned due to the rotation of the chamber to the removal chute which has an outlet valve.

Title: Light alloy pistons for IC engines - have inset piston ring holders of truncated cone design
Inventor: LEITGEB WALTER DIPL ING
IPC: F02F3/22
Filed: 1974-03-02
Abstract: Light alloy pistons have an inset truncated cone shaped ring carrier produced by the Alfin (RTM) casting process. The carrier has grooves to accommodate piston rings. The edges of the carrier are almost perpendicular to the piston axis and these help to minimise the stress on the carrier. Other designs have a double truncated cone or an inbuilt cooling channel. The carrier edges may have a sawtooth configuration on the side contacting the piston. The increased expansion of the aluminium piston ensures a better support and positioning of the insert, and the wedge-shaped cross section of he cooling channels promote increased heat dissipation.
Patent DE-2410966-A1 (DE)
Title: Tanker fluid discharge interlock - has poppet valve held open until cancelled by level gauge signal
Inventor: SIGWART REINHART
IPC: B65D88/54
Filed: 1974-03-07
Abstract: A poppet valve is located in the base of a tank of fluid, e.g. a road tanker, and is held in the normally closed position by a coil spring. When the contents are to be discharged into an outlet line, an actuator lever is moved through a fixed arc to raise the poppet from the seat. The actuator lever is held in the open condition by an interlock latch. When the level of fluid in the tank has diminished sufficiently a float type level gauge begins to operate an auxiliary actuator that eventually displaces the interlock latch. The main selection actuator, which is spring loaded, then operates to close the valve. This prevents the tank completely emptying and avoids air being taken into the discharge pipe.
