Abstract: Abstract of the Disclosure A Ripping Bucket Arrangement Among the variety of bucket arrangements that are commonly available, several are specifically designed for ripping applications in materials that are extremely hard to penetrate.  While these types of buckets are normally satisfactory in ripping hard, strong, brittle materials, their designs do not lend themselves to excavating and dumping weaker more plastic materials and thus exhibit little or no versatility.  The bucket arrangement of the subject invention includes a first and second ground penetrating means that are selectively positioned on the bucket with respect to each other.  The selective positioning allows sole engagement of either of the first or second ground penetrating means with the ground or simultaneous engagement of both penetrating means with the ground.  Such an arrangement provides superior operation in a ripping capacity and yet the selective positioning of the first and second penetrating means also permits excellent operation in weaker or plastic materials.

Abstract: ABSTRACT       Semiconductor Devices Employing Conductivity Modulation A semiconductor device, e.g. a lateral DMOS transistor or bipolar transistor, has a main current path (20) extending through a high resistivity body portion (1) of one conductivity type.  A minority-carrier injector region (6) which may be of the opposite conductivity type is provided in the body portion (1) in the vicinity of the current path (20) and serves with an applied forward-bias to inject minority charge carriers (16) which are characteristic of the opposite conductivity type into the body portion (1) to modulate the conductivity of the current path (20). In accordance with the invention one or more further regions (8) of the opposite conductivity type are located in the part of the body portion (1) in the vicinity of the current path (20) and within a minority-carrier diffusion length of the injector region (6) and/or of each other.  These further regions (8) float at a potential dependant on the minority-carrier injection (16) from the injector region (6) and serve to inject minority charge carriers (18) into areas of the body portion (1) remote from the injector region (6) so as to modulate the conductivity of these areas of the current path (20).  The floating regions (8) may be located within the spread of a depletion layer (30) from a reverse-biased p-n junction (2) to increase the breakdown voltage of the junction (2).  The body portion (1) may be, e.g., a MOST drain drift region or a bipolar transistor collector region or a thyristor base region.            (Figure 2).

Abstract: Abstract of Disclosure A method and apparatus for incorporating a powder into a continuous fibrous web containing multiple corrugations.  In the method, a fibrous web provided with multiple parallel corrugations is continuously passed over a curved surface having an arc with a radius to web thickness ratio of 0.5-3 and the corrugations are opened at their upper side, while any bonded fibers connecting adjacent corrugations together are broken apart.  A powder having 50-1000 micron particle size is deposited by gravity into the opened spaces between adjacent corrugations of the web.  The deposited powder is then compacted into the fibrous corrugated web by rubbing with a pad moved in an oscillating motion generally perpendicular to the corrugations.  The powder filled web is bent in the opposite direction around a roller to break the fibers between the corrugations on the opposite side of the web.  The second roller can be made vertically movable so as to convert the web continuous forward motion to an intermittent forward motion.

Abstract: ABSTRACT OF THE DISCLOSURE:          A stirrer having vertical buoyancy tanks fitted to its upper part and provided with rotors which generate horizontal and vertical propulsions, stirs liquid uniformly as it moves freely through a liquid storage tank.  This prevents the accumulation of sludge.  The vertical buoyancy tanks stabilize the stirrer, and provide a restoring force if the stirrer is upset.  The stirrer is fitted with an ultrasonic wave emitter,  and ultrasonic receptors are installed at several positions in the liquid tank.   An ultrasonic pulse is emitted after a certain interval when the stirrer is at rest on the bottom of the tank.  The position of the stirrer is computed for various emission periods,  and the average is taken to give the actual position of the stirrer.

Abstract: A wet electrostatic precipitation unit 1 for purification of moisture- and dust-laden gas comprises a condensation cooling unit 21, which is integrated in the installation's precipitation unit 20. Several discharge electrodes 4 are mounted within the screen electrodes 5 and these extend through the cooling unit 21. Devices in the form of distribution lines 50, 60 are positioned in the top and bottom in the precipitation unit 20 so that uniform distribution of coolant 23 is achieved over the external surfaces of the screen electrodes 5. The gas flows through the screen electrodes 5. The uniform distribution of coolant causes a reduction in corrosion rate on the inside surfaces of the screen electrodes 5, as a result of formation of condensate on these surfaces and is the result of the uniform and low temperature of the screen electrodes, and as a result of lower concentration of corrosive substances in the condensate. This entails both technical and economic advantages and also permits production of the screen electrodes from steel with relatively low content of alloying substances. <IMAGE>

Abstract: Unsaturated fatty acid derivatives which, besides fatty acids with two double bonds, contain fatty acids with more than two double bonds, are hydrogenated in the presence of a palladium, platinum or rhodium catalyst which has been treated with ethylenediamine or a homologue and/or a derivative thereof and at a temperature of -20 DEG to 100 DEG  C. The hydrogenation progresses very selectively while very little isomerization to trans-fatty acids occurs. For example, in the hydrogenation of soya bean oil to a linolenic acid content of 2%, the linoleic acid content only decreases to 45-52%. Under identical conditions an untreated catalyst leads to a linoleic acid content of about 35%.
