Date Jul. 8, 1982.Portable measuring instrument for measuring the clamping force between a pair of welding electrodes in spot welding. The instrument comprises a measuring cell (1) designed to be inserted between a pair of welding electrodes. The measuring cell contains a wire strain bridge for measuring the clamping force between the welding electrodes and a pair of electrodes (5) in a voltage detector for indicating the turning on of the welding current. The measuring cell is connected electrically to an electronic unit with optical indicating means (9), e.g. an LED stack, which indicates the magnitude of the clamping force when the welding current is turned on, and also the maximum clamping force attained during welding, and separately preserves the display of both of these values. The LED stack and the electronics are arranged in an apparatus casing (3).

Abstract: A method of manufacturing a jet nozzle plate utilizes a base plate in which a bore having a diameter which is larger than the inner diameter of the ultimate jet nozzle is provided in order to form a jet nozzle, after which on the front thereof a recess is milled which concentrically surrounds the bore at a distance. Subsequently, the base plate is covered as a unit, as far as into the bore, with a layer of a chemically depositable material, whose thickness defines the inner diameter of the bore to the inner diameter of the ultimate jet nozzle. Subsequently, the front of the plate is ground down as far as the layer in the recess and is etched, the material of the base plate exposed by grinding then being removed until the layer projecting from the bore forms a freely projecting cylindrical tube which is surrounded by a trough.

Title: Method for protecting against excess black radiation - involves using cooler transformer to transform radiation movement direction to even cooler air
Inventor: KOPONEN LAILA TUULIKKI
IPC: F24D19/06
Filed: 1981-11-05
Abstract: The radiation transformer, for medical use, uses so-called black radiation from a heated surface which passes to a cooler radiation transformer which transforms the movement direction of excess radiations to still cooler air. This occurs as it passes through the transformer channels, and the radiation combines with air molecules. This obviates damage to the mucous membranes of persons breathing in excessively radiated air.

Abstract: A superheater has a pressure vessel containing upper and lower steam chambers for primary steam between which extends a nest of tubes arranged around a central volume. The volume between the nest of tubes and the pressure vessel is divided into lower and upper volumes by a wall which forces the secondary fluid to be superheated first to pass the nest of tubes radially inwardly into the central volume and thereafter radially outwardly. Primary steam is supplied to the upper steam chamber tangentially and flows under condensation through the tubes to the lower steam chamber where the condensate is discharged. Between the steam chambers a centrally located return conduit can be provided. The rotation of the steam within the upper steam chamber induces a pressure distribution with decreasing pressure from the periphery towards the center which pressure distribution is used for the recirculation of excess primary steam through the return conduit.

Abstract: This system accepts compass outputs from a wide variety of compass output devices such as stepper and synchro devices having different coupling ratios, supply voltages and carrier frequencies. The system then, as part of a PPI radar system, electronically converts these compass outputs without the usual intermediary electromechanical devices into real-time analog reference signals properly phased with respect to the radar timing to provide an electronically stabilized PPI. This is achieved by comparing the points of equal amplitude of any two phases of gyro compass synchro output signals and using these major transition points to provide a digital code indicating the angular position of the gyro output shaft; a microprocessor then transforms the code, by comparison with a previously stored position code into coded position change signals which are then used to change a stored angular value, representing the course of the ship. These coded angular data are converted to analog sweep reference outputs applied to the deflection circuit of the display to provide a stabilized and oriented PPI display. Moreover, in cases where synchro coupling ratios are used, resulting in smaller angular changes in the synchro shaft position for a given change in course, minor transition points can be inserted between the major transition points to provide the correct step changes in the orientation of the PPI.

Abstract: The invention concerns a method, a shaping arrangement and a flux for electroslag welding of light metals. The method is carried out in that one sets up in succession the workpieces being welded, leaving a desired gap in between them, a shaping arrangement and an electrode, after which one fills the gap with a flux and generates a slag bath with subsequent melting of the electrode and the edges of the workpieces being welded under formation of a metal bath which is collected, maintained in the molten state and used to fill up the welding gap with the molten metal, followed by solidification thereof. The method according to the invention is characterised in that the metal bath is collected outside the gap on top of the workpieces being welded, while the gap is filled with the molten metal after the electrode and the workpieces being welded have been melted and the metal bath has accumulated in a quantity, volume, necessary to fill the gap, taking into account the degree of thickening of the weld. The method is carried out by means of a shaping arrangement, which contains chill moulds 9, a container 13, which is arranged above the workpieces being welded, and a container 14 which is arranged beneath the workpieces being welded. The shaping arrangement is characterised in that the chill moulds 9 are furthermore provided with porous elements 12 and configured with step- like lengthwise grooves 10, which are arranged to form a support surface 11, which carries the porous elements 12, which are arranged to form a cavity with the groove 10. The container 13 that is arranged above the workpieces being welded is further provided with outer and inner connection terminals 16, 17 and a strap 18, which is intended to interconnect the inner connection terminals 17. The holder 14 which is arranged underneath the workpieces being welded is furthermore provided with a transverse partition wall 27. The flux used during the electroslag welding contains cryolite, barium fluoride and alkaline metal bromide. <IMAGE>

Abstract: An improved fabric for covering dampener rolls comprising a ground yarn, a water shrinkable inlay yarn and a hydrophilic pile yarn. The fabric is fashioned into a cylindrical tube and is securely fastened to a roll by thoroughly wetting the tubular fabric and roll in water until the water shrinkable inlay yarn shrinks causing the fabric to tighten down on the roll. When the inlay yarn of the dampener cover shrinks it does so in a widthwise or circumferential manner, thereby exerting a force upon the surface of the dampener roll similar to the force exerted by a series of rubber bands, thus securing the dampener cover to the dampener roll. This unique fabric construction also allows for a reduction in lengths of fabric needed to cover a roll, because the fabric shrinks circumferentially and not lengthwise. Thus, a cover may be measured more precisely to the length needed to cover a specific roll.
