IPC: B21B45/08

Abstract: To apply a coating of a non-ferrous metal such as, for example, zinc to the surface of rolled steel to increase the corrosion resistance, it is proposed to descale the rolled steel continuously downstream of the rolling step from the rolling pass by applying pressurised water and, immediately after descaling and while preventing a renewed formation of scale, to cool it by means of water rapidly to a temperature suitable for hot application of the coating and finally to apply the coating. One of the advantages of the invention is that, both for descaling and for preventing the renewed formation of scale and for simultaneous cooling, only a single medium, namely water, is used, and the cooling can be controlled in such a way that the rolling pass can be exploited in an optimised manner for the coating. The result is that all process steps or treatment processes can proceed as a continuous extension of the rolling step, i.e. at rolling speed, so that the finished coated end product leaves the production line analogously to a normal, not aftertreated rolled product.

Abstract: A delay type flip-flop arrangement using transistor-­transistor logic receives a clock signal (CP) and input data (D) and outputs a logical output (Q) in accordance with the logic level of the data. The arrangement includes a master flip-flop (1) for transmitting a change in the logic level of the data to a pair of output ends (N1,  N1 ) when the clock signal is at a predetermined logic level; a slave flip-flop (2) for latching the data transmitted via the pair of output ends; an output buffer (3) for effecting a buffering of the data latched in the slave flip-flop; and a drive circuit (4) for driving the output buffer. The drive circuit responds to logic levels of data (Q1,  Q1 ) appearing at the pair of output ends of the master flip-flop and, based on the logic levels, drives the output buffer to determine the logic output (Q) to be output from the arrangement. This reduces the total propagation delay time and realises a high speed operation without increasing the power dissipation.

Abstract: A previously ignored property of a degenerate 2- dimensional gas of charge carriers in a quantum well (to be termed the quantum-capacitance effect) makes possible a novel class of transistors. In these devices the collector (53) (a quantum well having high transverse conductance) is located between gate (55) and emitter (50,51), with a barrier layer (52) between emitter and collector, and a relatively thin barrier layer (54) between collector and gate, and the chemical compositions and/or thickness of the various layers are chosen such that application of a voltage to the gate results, as a manifestation of the quantum-capacitance effect, in an induced charge in the emitter, whereby a current between emitter and collector can be controlled by means of a voltage applied to the gate. Transistors according to the invention potentially are very fast. Exemplarily the invention is embodied in a GaAs/AIGaAs heterostructure.

that each support wheel (3) consists of a single substan­tially circularly-cylindrical rim (56) of rigid material, such as steel, about which there are placed at least three rolling tyres (55) of elastomeric material, the axial width of which diminishes with increasing radius. 
     This arrangement makes it possible to reduce maintenance costs and to achieve a highly desired sound and shock absorption using relatively low-costs means.

Abstract: A porous substrate of a fuel cell electrode assembly is formed by producing a fibrous carbon precursor web by means of a conventional wet paper­making process. The precursor web is then dried and saturated with a wet resinous binder which will carbonize when heated. Substantially the entirety of all of the carbon fibers in the web are thus coated with the binder, and substantially all of the inter-fiber junctures in the web will also be coated with the binder. The saturated web is then dried, and heat treated to convert the binder to a glassy carbon which exhibits superior resistance to corrosion.

Abstract: Resin stream shut-off control apparatus in a multi-­layer extrusion die head enables the continuous formation of a multi-layer plastic resin parison tube suitable for blow-molding and having alternating sections X, comprised of layers formed from all the resins introduced into the die head, which sections are encaptured by one or more blow mold(s) for forming blow-molded articles, especially containers, and sections Y having portions devoid of selected one or more of the layers (which would usually be formed from the relatively more expensive of the resins) which sections Y do not comprise the final article (container) and therefore become flash or scrap. 
     The resin stream shut-off control apparatus includes an assembly which can intermittently and selectively shut off flow of the selected one or more resin streams thereby preventing them from forming layers in parison sections Y. The apparatus is comprised of movable means (18a), and a die element (31) which define a resin channel orifice (at 31a) between their surfaces (26, 28) and which cooperate at or adjacent the orifice to prevent flow of the selected stream(s) through the orifice. The movable means (18a) and die element (31) can   be caused intermittently to abut one another, and preferably there is no die structure just downstream of the downstream-most abutting contact point (31a), i.e. in a merge area (MA) where the selected one or more resin streams merge with the other extruded resin streams. The movable means (18a) can be a sleeve element and this and the die element (31) have juxtaposed corresponding angular surfaces (26, 28) which in the shut-off position abut or fit flush against one another to shut off resin flow through the orifice. The assembly can be used to modulate, rather than or as well as shut-off, flow of the selected one or more resin streams, for example, to form one or more layers therefrom which vary in thickness in parison section X and in the resulting article or container. 
     Methods are disclosed for forming a container having a scrap layer substantially devoid of the selected one or more layers and constituent resins, and a multi-­layer extrusion blow-molded article or container has a layer which includes scrap derived from the aforesaid parison sections Y.
