Title: Metering system for additions to water streams - using the water pressure to actuate metering pump
Inventor: PREISIG JUERG
IPC: C02F1/68
Filed: 1975-04-10
Abstract: Metering system for metered addition of additive to a flowing medium, esp. water, in which the pressure fluid line to the main control valve is connected to the water line to which the additive is going. This then serves as hydraulic fluid for the metering pump. The main control valve then serves to connect the metering pump with the hydraulic supply in one posn. and with a waste discharge in the other. It thus serves as a pressure transducer between the air or other gas used on the control circuit and the water used to rive the pump. of use when additives are being metered into water, or other flowing fluids. Conventionally the compressed air used in the control circuit would be used to power the metering pump. However in some circuits, this could lead to contamination. Also in high pressure systems there are problems. The system described confines the gas to the control circuit and thus allows other gases such as propane or CO2 if this is convenient.

Title: Tractive force measuring test bed - has bearing-mounted transducer allowing measurements at different angles
Inventor: BROSA ERICH
IPC: G01L5/00
Filed: 1975-05-23
Abstract: The test bed consists of two measuring platforms at right-angles mounted on a common base (34). A central boss (36) has a roller bearing (23) at its lower end, and contains a strain gauge or similar transducer. As the stiffness of the material link (20) across the direction of measurement is very high, measurements can be resolved into two components at 90 degrees. To fit the force- measuring bearing as closely as possible to the bearing plate, all three platforms have a channel (35) so that initially, there is a certain amount of play between the two lower platforms (33, 34) and the transducer housing (36). In the operating position, after a certain amount of travel by the transducer housing, it comes to rest in the channel and overload is prevented.

Title: Electroslag remelting using transverse magnetic field - which reduces size of molten metal drops and increases melting speed
Inventor: WINTERHAGER HELMUT DR ING
IPC: C22B9/18
Filed: 1975-08-16
Abstract: Iron, steel, and non-ferrous metals or their alloys are refined by electroslag remelting. In using a cooled copper mould made of two or more segments, a non-magnetic steel or alloy core is located in the air gap of a choke so that a transverse magnetic field is created between the bottom end of the consumable electrode and the molten pool of metal. A direct or alternating magnetic field may be employed by using direct or alternating current to feed the choke coils. The transverse field is pref. used to control the size of the metal drops and to rotate the slag and/or the molten pool. The electrodynamic forces reduce the size of the metal drops falling from the consumable electrode, increases the interaction of metal and slag, and thus raises the speed of melting by 20-30%.

Title: Separate capacitors obtd. from a mother winding - by high speed multiple cutters with winding enclosed in die
Inventor: PETRICK PAUL DR
IPC: H01G4/32
Filed: 1976-02-10
Abstract: Numbers of separate capacitors are produced from a mother winding prepd. from at least two metal foils sepd. by a dielectrical film of a polyester, polycarbonate, etc. and the roll produced is cut through transversely to its length forming the separate capacitors, to which wires are attached at their end faces by welding. The cutting is effected by a shear blade moving at a speed close to the speed of propagation of the elastic waves generated in the winding by the interaction of elastic forces and the forces of inertia. Before cutting, the winding is pressed flat, enclosed in a die and the winding is sheared through at a number of points simultaneously. A simple and economic method for producing capacitors capable of accommodating high loads, as well as capacitors with a very narrow width of foil, e.g. 3-5mm. The synthetic material and the metal foil at the sheared edges are flush. There is no relative displacement of the layers and no heating.

Title: Reversible axial flow fan - has blades pivoted from one position to another by their own inertia force
Inventor: HOFMANN HANS DIPL ING
IPC: F04D29/56
Filed: 1976-02-21
Abstract: The fan has an impeller wheel bolted together from two halves (40, 41) with a recess between them which grips the root (43) of a blade (42). A spring (46) presses the blade root radially outward and also turns it against an end stop. The blade root is not central on the blade so that when the rotation is reversed the inertia forces of the blade pivot it about the root against the spring torsion to bring it against a second end stop in a position suitable for reverse flow. A plunger (51) is normally depressed by a spring (52). At full speed either direction centrifugal force moves it out against the spring (52) to lock the blade root in whichever of its two positions it is.
