Abstract: 1498847 Detecting metal objects ASEA AB 10 April 1975 [11 April 1974] 14734/75 Heading G1N In a presence detector output signals are analyzed to determine whether or not they are produced by an object to be detected. In a metal detector a conveyer conveys material at a known speed past a detector in the form of magnetizing and detector coils arranged above and below or at the side of the conveyer the output signal, Fig. 2 is analyzed to ascertain whether it is a true signal formed by the presence of a metal object in the material or a false signal. This is achieved by determining the periods Tl and T3 during which the positive and negative pulses exceed the threshold levels V 1 , V 2  and the period T2. If the period T2 is less than a predetermined period and the periods Tl and T3 exceed respective predetermined times the presence of an object is indicated.

Abstract: A sheet withdrawing mechanism is disclosed for a collator having a plurality of spaced moving shelves or partitions forming pockets. Each partition or pocket receives a pile of sheets and as each pocket passes sheet withdrawing position, rotating spiders, preferably having a plurality of arms, each extend an arm into each pocket in succession, engage the top sheet of the pile and at least partially withdraw the sheet far enough to be reached by adjacent secondary withdrawing mechanism which completes the withdrawal of the sheet from the pocket. Two constructions of spiders are illustrated and described, one having relatively long arms for partition spacing having a relatively large dimension so that the arc of movement of the end of each arm is great enough to withdraw the sheet sufficiently solely by the sweep of the arm. The second spider construction is for partition spacing having a relatively lesser dimension so that a greater number of pockets can be provided in an over-all dimension. This second spider has relatively shorter arms and has a withdrawal roll on the end of each arm which is rotated so that each sheet is partially withdrawn from its pocket by a combination of the sweep of the arm and the rotation of the withdrawal roll. Also included is mechanism to advance the phase of the spider arms with respect to the phase of the pockets as they rotate. Thus, the spider arms are advanced and enter the pockets progressively sooner.

Abstract: Instabilities in the leakage current and threshold voltage of a field-effect transistor (FET) on an insulator, at both room temperature and after operation at relatively high temperatures (150 DEG C), are substantially reduced by selectively doping edge regions adjacent to the transverse side surfaces of the channel region of the FET. The selective doping comprises implanting atoms into these edge regions, as by ion implantation or diffusion, to provide therein a carrier concentration of at least 5x1016cm<->3 atoms of the opposite conductivity type to that of the source and drain regions of the FET.

Abstract: A scarfing nozzle for producing a fin-free scarfing cut at least as wide as the width of the nozzle. The nozzle comprises an oxygen gas passage terminating in a nozzle discharge orifice characterized by having a central section and at least one end section. The central section is defined by parallel upper and lower edges and is adapted to discharge a sheet-like stream of cutting oxygen of uniform intensity across the metal body to be scarfed. The end section is defined by having at least one of its edges inclined such that the height of the end section is gradually reduced to a lesser value towards the side edge of the orifice but remaining greater than zero at the edge so as to diminish the intensity of the oxygen stream towards the edge of the orifice to the point where the flow of oxygen discharged at the edge is insufficient to scarf the workpiece but sufficient to produce a fin-free scarfing cut at least as wide as the width of said nozzle. This structure allows a plurality of nozzles to operate side-by-side to produce fin-free cuts of preselected width.

Abstract: In addition to a priming stage (11), the timing chain has at least two stepping modules (12, 13), of which each has a 5/2-way valve constructed as a pulse valve. The 5/2-way valve (53) is constructed and wired in such a way that during priming by a setting signal of a preceding stage (11) it is held by the continuing signal at the associated signal input (29) in a position in which its associated signal output (25) receives no compressed air. The timing chain (10) therefore remains stationary at the particular point even in the event of a permanent signal of a defective limit switch, without skipping a step and running on. <IMAGE>

Abstract: In order to be able to unload the powdery product (5), for example whole-milk powder, from a silo (4) through an unloading aperture connected to an outlet pipe (8) and arranged in a filter-like plate (6), the product (5) is aerated through the plate (6) and, at the same time, the plate (6) is made to vibrate vertically by a vibrator (26). In this case, it is important that the aerating and the vibration regions are spatially not or hardly separated from one another, and that the joint action of the aeration and the vibrations extends up to the unloading aperture. Such a method makes it possible to cause adherent powdery products to flow continuously, it being possible for the outflowing quantity to be influenced by the quantity of air supplied. <IMAGE>

Abstract: SO2 is absorbed from hot flue gas by spray drying a Ca(OH)2-containing suspension in the flue gas. Fly ash is left in the flue gas which is to be treated in the spray absorption process, and the powder which is produced by the spray absorption process and which consequently contains the fly ash and partly reacted Ca(OH)2 is partially recycled. Operation is controlled to obtain a temperature of the flue gas after the treatment which is 8 DEG -20 DEG  C. above the saturation temperature of the flue gas at this stage. The process leads to optimum use of the Ca(OH)2 used as absorbent and of the neutralization power inherent in the fly ash. Problems due to sedimentation of the absorbant before its atomization are avoided.

Title: Explosive cladding of fabricated metal articles - with multi-layer cladding sheet
Inventor: CHUDNOVSKY A D
Filed: 1981-09-02
Abstract: Explosive cladding of a metal article is carried out with a multi-layer cladding sheet. This comprises, on the side away from the article, the actual cladding material. On its inner surface is an intermediate layer, and inside this again, a bonding layer. The chemical base of the bonding layer is the principal element of the article to be clad. The intermediate layer includes at least one metal, with chemical properties which prevent diffusion between the cladding material and the bonding layer. This can prevent the formation of unwanted carbides, or compounds of ferrous and non-ferrous metals. Process is suitable for use in large fabricated constructions, e.g. pressure vessels etc. as it does away with the need for high temperature treatment after cladding. It also reduces danger from the formation of fragile intermetallics etc.
