Abstract: Resistance welding electrodes and processes using the same are provided.  The electrodes have a base portion and an integral nose portion projecting therefrom, with the nose portion terminating in a welding tip face.  The nose portion tapers inwardly between said base portion and said welding tip face with a concave profile taper such as a frustum of a vortical surface.  The electrodes used may be made up of a conventional copper material having copper combined with one or more metals selected from the group consisting of chromium, zirconium, cadmium, cobalt, nickel, beryllium, tungsten, aluminum, tungsten carbide, iron, and molybdenum; or, may be made of essentially pure copper.  The electrodes may be used in a welding process, which provides for a generally linear increase in current stepping with reduced or eliminated conditioning of the electrodes.  The welding tip face has a convex curvature which may range between about a two inch and a eight inch radius of curvature, and which preferably has a radius of curvature of about four inches.  Both male and female electrodes may be used with cooling recesses in the electrodes as well as an offset nose portion.  The diameter of the welding tip face may be about equal to the length of the nose portion.

Abstract: Type A, especially type 4A zeolites are well adapted as detergent builders, said zeolites comprising (i) primary particles having a mean particle diameter ranging from 0.1 to 10 mu , (ii) a cation exchange capacity in excess of about 100 mg CaCO3/g of anhydrous material, and (iii) a rate constant, relative to the surface area of the zeolite per liter of wash solution, in excess of about 0.15 s-1 lm-2. The builders are prepared by first determining the value of the rate constant for a given zeolite sample. Since a higher rate constant value corresponds to a lower degree of salt incrustation on fabrics, only those zeolites having a value above the predetermined minimum will be incorporated into detergents. Thus, zeolites otherwise appearing identical can be differentiated, with only those not causing high levels of incrustation being selected.

Abstract: A method of introducing supply air into a lower portion of a room space (3) directly to an occupied zone (7) by means of at least one elongated air distribution means (1) provided with a plurality of outflow openings (2) for supply air. In order to blow supply air into the occupied zone without draught and without drawing impurities from the upper portion of the room space, supply air is blown from the air distribution means at a high speed but through outflow openings so small that the speed of the air jets (A) from the openings is reduced essentially over a short distance (X) and the entrance of secondary air (B) from the room space into the air jets is prevented in the vertical direction of the room space over said distance (X) and at least at one end of the air distribution means. The air distribution means (1) is provided with a plurality of small outflow openings (2) the distance of which from each other in the longitudinal direction of the air distribution means is great as compared with the size of the outflow opening for enabling secondary air to flow from the room space in between the outflow openings, and to mix with the air jets from all sides.

Abstract: The subject of the invention is a drum screen for conditioning and classifying granular material with an input device at the one end of the drum which rotates about its lying longitudinal axis and an output device for the conditioned material at the other drum end. The output device connects to an annular space which is formed between the drum and annular screen sections which are located one after the other in the longitudinal direction of the drum and concentrically surround the drum. The mesh width of the annular screen sections changes in such a way that the section with the smallest mesh width is the annular screen section nearest to the output device and the section with the largest mesh width is the annular screen section at the greatest distance from the output device, preferably located in the region of the input device. Between every two successive annular screen sections (7a, 7b), a channel-shaped profile (29), with the open side directed outwards, concentrically surrounds the drum (2) at a distance of the width of the annular space. The profile engages with a number of hook- shaped mounting elements (28), distributed over the circumference, over the respective profile flange of the annular screen sections ending at it, the annular screen sections being located with initially still extended hook parts (28b) essentially free of play between two channel profiles spaced in the longitudinal direction of the drum and being held after installation in the installation position with the hooks bent about the free flange ends during installation. <IMAGE>

Abstract: A brightness limiter (76) is responsive to a beam current control signal in a predetermined range of beam current operating values with an extended operating threshold for reducing brightness and reducing beam current. Operation of the brightness limiter (76) responsive to certain noise in the beam current control signal during retrace is inhibited, the brightness limiter being otherwise responsive to the beam current control signal at operating values below the threshold. operation of the brightness limiter (76) may be inhibited by passing the beam current control signal through an AC filter. Alternatively, operation of the brightness limiter may be inhibited during retrace by interrupting propagation of the beam current control signal, or by preventing operation of the brightness limiter, for example, responsive to flyback pulses or pulses in timed relationship to flyback pulses.

Date Jul. 21, 1994Tuning a combiner filter, which includes two separate tuning modes: coarse adjustment applied when the combiner is taken into use by utilizing a measuring branch for forward power and a coarse measuring branch for reflected power; and fine adjustment applied in continuous operation by utilizing the measuring branch for forward power and a fine measuring branch for reflected power. The two-stage adjustment decreases the mutual interference of the filters during tuning. The correct tuning frequency of the combiner filter is obtained as the average point of the reversing points obtained in the adjustment process, the filter being driven to the average position. This so-called positional average tuning has two advantages: the effect of noise present in the power measuring line is reduced, and the tuning error caused by the termination of the dynamics of the A/D converter positioned after the detector at low power levels and good combiner filter settings is diminished. Power measurements are made frequency-selective by mixing.

Abstract: A process for the production of carboxymethylates comprises reacting alcohols, ether alcohols, or alkyl phenols with an aqueous solution of at most a stoichiometric amount of free chloroacetic acid and twice the stoichiometric amount of an aqueous base. The chloroacetic acid and base are added separately, but simultaneously under agitation (at elevated temperature and under reduced pressure) to the alcohol or alkyl phenol. The water content in the reaction mixture, during the entire reaction, is maintained at 0.3-1.5% by weight. Increased selectivity results and it now becomes possible to use aqueous chloroacetic acid in this process.
