Title: Revolving tube melt refining furnace - has non-circular internal cross-section
Inventor: TANOUE TOYOSUKE
IPC: C21C1/00
Filed: 1971-09-16
Abstract: The furnace with in- and outlets at opposite ends has a non-circular cross-section interior, the cross-section of which may be barrel shaped, elliptical or polygonal.

Title: Hot rolled bar steel cooling pipe - with additional fore-nozzles
Inventor: PECHAU GERHARD DR ING
IPC: B21B45/02
Filed: 1972-03-25
Abstract: The cooling device for steel bar stock comprises several lengths of coolant filled pipes through which the material is passed.

Title: Heat insulating cover for roof and outside walls - made from rigid foam plastics with keying features at edges
Inventor: STUMM KARL
IPC: E04F13/18
Filed: 1973-06-27

Title: Cable shaft made from reinforced concrete - includes baseplate, wall plates and covering plates
Inventor: STEWING ALBERT
IPC: E02D29/12
Filed: 1973-07-31
Abstract: The cable shaft is built up from component plates made from reinforced concrete. The plates are joined by dry joining and no filling compounds are used. The end plates have U-shaped stiffening elements in the horizontal section and L-shaped stiffening elements and in the vertical cross section. The arms of the U-shaped section form connections with the wall plates and the L arms form joints with the top cover. The top cover rests on the step formed in the stiffening arrangements. The cover plate is placed on the stiffening elements and hence it prevents the tilting of the stiffening elements. These plates are readily assembled.

Title: Flame start system for fuel injected engines - magnetic injector and start jet is combined as one unit
Inventor: EBLEN EWALD DIPL-ING DR
IPC: F02N19/06
Filed: 1973-08-03
Abstract: The fuel lift pump is double acting, whereby the piston is moved one way by a cam turned by the injector pump and in the other direction by a return spring. The lift pump gives a pressure of 2 bar which is then fed to the injector pump feed pipe from which a branch pipe is taken to a magnetic injector valve which may be regulated by an engine speed dependent cam which also controls the high tension ignition. The injector may also be fed by a branch pipe which contains a pressure switch and causes the magnetic valve to open when a predetermined pump pressure is reached. The pressure switch regulates the ignition and replaces the cam. The injector needle has an annular groove in the part which extends outside the injector nozzle.

Title: Snap closure for flexible bags - with a first section with flexible flap and second section stiffer than the first
Inventor: KRAWAGNA ALOIS A
IPC: B65D75/58
Filed: 1973-12-19
Abstract: Snap closure for flexible bags made of a first section consisting of an elastic flexible flap and a second section with a flexible stay along an edge and forming a flexible collar which is stiffer than the first section and tends to take up a shape corresponding to a non tension state when that edge extends along a straight line. This means that the edge and the stay become straighter when the first section is brought into a flat shape permitting the first section to be bent in between two stable positions of the closure.

Title: Centrifugal casting esp. of electric motor stator windings - using cool resin feed nozzles not in contact with hot moulds
Inventor: HALM RICHARD
IPC: B29C39/24
Filed: 1974-03-28
Abstract: A centrifuging casting device for cast resin prods., esp. electric motors, has the casting moulds arranged in a ring on the rotor, with their inlets oriented radially inwards and horizontally towards the rotor axis; a cool reservoir of resin mounted coaxially on the rotor is maintained at a temp. below the setting temp. of the resin and is connected to feed nozzles pointing radially outwards towards the inlets of the mould and terminating without contact with these moulds or inlets. The resin is thus projected into the moulds by the centrifugal effect and the nozzles are never in contact with the resin in the hot moulds. Pref. a sensor is mounted in the inlet of each mould and provides a signal to shut off a valve in the associated nozzle when the mould is filled. No clogging of the nozzles takes place since the resin in them is always cool.

Title: Newspaper chain conveyor for motion in several planes - has interlocking load tray support for automatic level compensation
Inventor: ANIKANOW NIKOLAI IWANOWITSCH
IPC: B65G17/48
Filed: 1974-06-19
Abstract: A chain conveyor for transporting newspaper stacks carries load trays which are attached to the conveyor chain by means of support arms. The anchor point forms a pivot so that when the plane of the conveyor movement changes, the load tray is able to remain horizontal. The support arm pivot carries a spur gear wheel. It is in mesh with a second gear wheel which is located on the pivot of the anchor frame. The same pivot carries a tooth wheel. A spring loaded lever retains the tooth wheel and thus the load arm assembly in a fixed position during straight line conveyor travel. When the load arm moves through a curved conveyor section fixed pins on the conveyor track rotate the tooth wheel step by step so that the load tray retains its horizontal orientation.
