Title: Induction furnace for oxidation - uses radiation from steel rod to preheat zircon tube to temp. adequate for inductive coupling
IPC: C03B37/029
Filed: 1976-02-25
Abstract: The induction furnace (c. 2000 degrees C) for heating materials in an oxidising atmosphere, consists of a zircon heating tube around which is wound a cylindrical inductor. The tube is surrounded by thermally insulating material. Since zircon has a high resistance at room temp. it is necessary to reduce this resistance before inductive coupling can take place between the inductor and the zircon tube. This is achieved by inserting a refractory non-oxidisable steel rod into the furnace. The rod is heated by induction and heats the zircon tube by radiation. When the zircon tube's temp. is high enough for inductive coupling to the inductor the steel rod is withdrawn. The charge can then be introduced and heated by radition from the now inductively heated zircon tube.

Title: Mould for aerosol cap and trigger assembly - forms amply long nozzle and lever with rigid valve socket
IPC: B29C45/26
Filed: 1976-06-02
Abstract: An injection for the production of a cap, esp. a combined delivery lip and cap for the outlet valve of an aerosol container, has a punch fitting in the female component of the mould, and accommodating a cylindrical plunger. The plunger has a cylindrical surface of the same diameter as the internal diameter of the inner socket which fits on the valve housing, and a top surface corresponding to the under surface of the cap assembly. On the cylindrical face of the plunger there is a projecting extension of the same dimension as the outer diameter of the inner socket. This forms a cutout for the delivery lip lever in the depressed position. Diametrically opposite to this projection a pair of projecting parts arranged close together and having the same diameter as the inner cylindrical wall of the inner socket, form two cutouts separated by a strip which acts as a hinge for the delivery lip lever. The plunger slides in the punch in a bore of the same diameter as the outside diameter of the inner socket. The top surface of the punch has a contour corresponding to the remaining parts of the undersurface of the assembly of delivery lip and cap. The outer diameter of the punch is the same as the internal diameter of the outer socket of the cap, whilst the cavity of the mould forms the outer surface of the outer socket, and its bottom surface coresponds to the top surface of the cap assembly. The combined cap and operating lip assembly is produced in one operation. The lowest zone of the inner socket is continuous so that no stiffening or similar reinforcements are necessary to hold it in place, since the force it exerts on the outlet valve housing is increased remarkably, and the jet is projected at right angles to the centre line of the container.

Title: Transferring a web from the press section of a paper machine - using a transfer suction roll (SW190776)
IPC: D21F3/10
Filed: 1976-06-18
Abstract: A transfer suction roll for transforming a paper web from the press suction of a paper machine towards the drying section. The rotating transfer roll has a perforated shell through which suction is applied to the web. It contains a stationary suction chamber which is situated outwardly beyond the shell closely adjacent to at least one of its ends. The suction chamber connects with the perforations in the shell, and there is a seal which seals the area through which the suction chamber communicates with the perforations at any given instant. The method eliminates the requirement for the seal water used with conventional rolls, with its attendant problems. The transfer suction roll also gives very effective detachment at the margins of the web, which eliminates the tendency of the webs to break starting from the margin.
