Title: Electroslag remelting of metals - using inert gas jets directed at immersed electrodes to promote slag flow and improve melting
Inventor: MEDOVAR BORIS I
IPC: C22B9/18
Filed: 1980-04-30
Abstract: An electroslag remelting method comprises melting down at least one consumable electrode in a liq. electrically conductive slag and blowing a gas into the slag by means of a jet directed towards the electrode. The gas is blown with enough force to create a flow of slag around the slag-immersed portion of the electrode. The gas jet velocity of the nozzle outlet is pref. 0.5 m/s per mm of distance between nozzle and electrode. The flow rate in an multi-electrode system is controlled in proportion to electrode immersion depth. The method is esp. useful in multi-electrode systems, in which it eliminates unbalance in the melting-down rate of the electrodes. The melting down rate is increased, controllably, and thus provides savings in power consumption and uniform melting.

Title: Stag call
Inventor: DRAEBING WALTER
IPC: A01M31/00
Filed: 1981-03-12
Abstract: A stag call is a device which is used by hunters to imitate the call of the stag. It consists of a tubular hollow body which has a mouthpiece (4) at its one end and, at its other end, a sound outlet aperture (6) which can be covered or uncovered with the hand. Conventional stag calls consist of relatively rigid plastic, or even of glass, so that in the event that the stag call accidentally knocks against a button on the hunter's clothing, his binoculars or the like, a harsh sound is caused which is alien to the forest and to which stags are particularly sensitive. The object of the invention is therefore to develop a stag call in such a way that no harshly metallic sounds occur if it unintentionally knocks against a hard object. This is achieved in that the tubular hollow body is provided with a substantially continuous undulating pipe (1) on which the mouthpiece (4) and the sound outlet aperture (6) are moulded, and in that the entire stag call consists of rubber or a similar flexible material. <IMAGE>

Filed: 1981-03-17
Abstract: In a further improvement to the process of principal application P 3021369.5, granular, free-flowing crude tetrafluoroethylene polymer powders which cannot be processed from the melt, comprising from 0.004 to 0.075 mol% of polymerised units of a perfluoroalkyl vinyl ether of the formula CF2=CF-O-Rf, in which Rf is a perfluoroethyl, perfluoro-n-propyl or perfluoro-n-butyl radical, and polymerised tetrafluoroethylene units, can be obtained by maintaining a stirrer speed corresponding to a specific power consumption of from 0.5 to 1.5 watts/l of aqueous medium, measured in the aqueous medium before commencement of the polymerisation, in a critical phase of the polymerisation process, commencing on formation of from 1.5 to 3% by weight and extending as far as the formation of from 8 to 12% by weight of polymer solids in the suspension polymerisation with stirring. These measures allow the bulk density of such crude polymer powders to be increased to 880 g/l, the flowability achieves values of 2.5 s/50 g, and the particle stability achieves values of 2.5 s/50 g. A further improvement on conversion into ram extrudates is thus achieved.

Title: Process for staining sheet glass by diffusion and reduction of silver ions
Inventor: MORIMOTO HIROSHI
IPC: C03C21/00
Filed: 1981-12-08
Abstract: The invention relates to a process for staining sheet glass, which must contain reducing ions, such as tin ions which have diffused into the surface layer thereof. The reducing ions can originate from a bath of molten metal which was used in the production of the sheet glass by the float process. A staining agent, which contains a pulverulent mixture of 1 part by weight of a substance of the formula AgxWyOz, wherein x:y:z = 1  APPROX  2:1:2  APPROX  4, and 5 to 20 parts by weight of a transition metal oxide, for example Cr2O3, is applied to the surface of the glass plate or sheet glass, and the glass plate or sheet glass is heated in such a way that silver ions are caused to diffuse into the surface layer of the glass plate or sheet glass and undergo a reduction due to the action of the previously diffused ions, to form a staining. Advantageously, a paste is used which was prepared by dispersing the pulverulent mixture in an organic liquid carrier. As a consequence of the stability of the silver-containing oxide AgxWyOz, uniform staining is achieved without incurring difficulties and without the quality of the sheet glass deteriorating.

A reversible cover plate which can be coupled to the bearing seat is provided, and so too is a holding part, such as, for example, a cone, a turning bolt, a bearing lug, cloverleaf cone, etc, which is fastened in one piece to the cover plate. The bearing part is brought to the top for projecting during operation in order to fasten the cargo and is held under the bearing plate in the slot of the bearing seat when the cover plate is turned over to the bottom. A T-shaped bar is passed perpendicularly through the cover plate in a freely movable manner and has at one end a transversely running handle key which with regard to the holding part lies on the opposite side, a stop piece being provided at the other end of the T-shaped bar. A notch or an extension is provided at the bottom end of the holding part and a pair of wedge parts are arranged beneath the slot. The wedge parts come into engagement with the notch, the extension or the handle key in order to fasten the cover plate relative to the bearing seat. Water-tight packing rings are provided on the cover plate and the bearing seat at the necessary locations. Consequently, when the holding part is fitted so as to be positioned upwards on the deck, the hatch cover or the tank top of the loading area, it can be used to fasten cargoes. When the holding part is in its reversed position reaching down into the slot and is turned into the locking position, the cover plate can hold the upper surface of the fastening device in alignment with and in the same plane as the surface of the surrounding components. In this way, the device can be kept water-tight and free of dirt from water and cargo sediments which could otherwise penetrate into the recess of the bearing seat through the slot. <IMAGE>
