Abstract:
A pastil box has a pivot lid (24), the skirt of which has an internal edge (26) cooperating in a snap locking manner with a folded-over flap (20) at the front edge area of the box mouthing. This flap (20) protrudes from an edge area (30) which, as a whole, is resiliently depressable into the box, whereby a snap locking is achieved which will be substantially independent of the manufacturing tolerances of the box. Also the locking and in particular the release of the locking by the opening of the lid will take place in a manner that is very convenient for the user, because the spring action after the release of the locking will contribute to the opening of the lid.
Abstract:
The invention deals with a sales and dispenser box of the pocket carried type and of the type having a hinged hood- or cap-like lid with a lid panel (36) and lid skirt portions that cover the mounting sides of the box. It is desirable to arrange for a snap locking of the lid in the closed condition thereof, but this has been difficult particularly for lids of the cap type. The invention provides for an effective snap locking with the use of laterally projecting ear portions (70) on the opposed side edges of a front panel portion (58) of the box and respective recesses (56) in the insides of the opposed lateral lid skirt portions (50, 52), these recesses being provided between the inner side of the front lid skirt (36, 60), adjacent the corners thereof, and the edges (56) of side flap portions (52) of the lid panel (36) folded flat against the outer lateral lid skirt portions constituted by side folded outer flap portions (50) of the front lid skirt (48). The hinged lid is effectively snap locked when the projecting ear portions (70) are received in the recesses (56) in the closed condition of the lid.
Abstract:
Die Erfindung betrifft einen Festwalzrollenkopf (1) eines Festwalzwerkzeugs zum Festwalzen von Radien oder Einstichen (22) an den Haupt- und Hublagerzapfen von Kurbelwellen (21) mit einem Gehäuse (2), in welchem eine oder zwei Festwalzrollen (4) in seitlichem Abstand voneinander mit geringem Spiel jeweils in zwei Rollenkäfigen (5, 6) lose drehbar geführt sind. Die Rollenkäfige (5, 6) sind auf der der Kurbelwelle (21) zugewandten Stirnseite (3) des Gehäuses (2) mit Haltern (15) befestigt, welche die Rollenkäfige (5, 6) jeweils auf ihren den Festwalzrollen (4) abgewandten Stirnseiten (10) abstützen und zugleich seitlich führen. Das Gehäuse (2) ist auf seiner der Kurbelwelle (21) zugewandten Stirnseite (3) an deren beiden Enden jeweils mit einem Vorsprung (11, 12) zum Abstützten von je einem der beiden Rollenkäfige (5, 6) versehen. Ein Befestigungs- und Führungsorgan (15) für den jeweiligen Rollenkäfig (5, 6) ist vorgesehen und greift in den Rollenkäfig (5, 6) ein, wobei es zugleich an einem der Vorsprünge (11, 12) des Gehäuses (2) befestigt werden kann.
Abstract:
A drafting apparatus (10) comprises a frame (12) on which is mounted rollers (14) made up of two elongate cylinders. The rollers (14) are connected to each other by a polymeric band (24). In use of the invention a drafting instrument such as a rule is mounted on the apparatus (10) which may be pushed on a drafting surface.
Abstract:
The present invention relates to a shaft furnace as well as a method for operating a shaft furnace. For example, the present invention relates to methods for operating a shaft furnace which include charging an upper region of the shaft furnace with raw materials; the raw materials sink in the shaft furnace under the influence of gravity and a part of the raw materials is smelted an/or at least partially reduced under the effect of the atmosphere prevailing within the shaft furnace. The methods further comprise admitting an addition gas via at least one addition opening spaced from a lower admission opening and/or discharging a shaft furnace gas via a shaft furnace gas line to provide discharge of gaseous reaction products from the interior of the shaft furnace.
Abstract:
Method for operating a shaft furnace, whereby an upper section of the shaft furnace is charged with raw materials which due to gravity descend inside the furnace while the atmosphere prevailing within the shaft furnace causes part of the raw materials to melt and/or to be reduced, and in a lower section of the shaft furnace a process gas is injected so as to at least partly modify the atmosphere prevailing in the shaft furnace. The pressure and/or volume flow of the injected process gas is dynamically modulated within a time span of 40 s. Also, a shaft furnace operable by said method, thus achieving improved through-gassing.
Abstract:
The process includes two major phases, each including a converter blowing step and a discharge step, whereby the first discharge step is also a preparatory step for the second blowing step. The steel is dephosphorized, desulfurized, and decarbonized under formation of basic slag which is retained in the converter during the first discharge. Lime, limeflux and possibly clay is added prior to the second blowing together with, preferably, silicon for deoxidation. After the second discharge, additional alloy components may be added.
Abstract:
A sales and dispenser carton box having in its top panel a dispenser opening normally closed by an internal closing plate portion constituting an integral part of the blank from which the box is erected and being displaceable to open and close the opening, the closing plate being hinged to the free edge of an end panel portion of the box pivotally secured to the box along its opposite edge, and the closing plate being held slidingly against the inner side of the top panel by means of at least one side flap projecting from the side edge of the closing plate down along the respective side panel of the box so as to be slidingly supported by an elongated rigid portion of the box. The box may be designed so as to have a breakable seal.
