Abstract: 702,891. Weighing-apparatus. SCHENCK MASCHINENFABRIK DARMSTADT GES., C. Sept. 11, 1952 [Oct. 2, 1951], No. 22862/52. Class 143 In a weighing arrangement, for unsteady loads, an elastically - coupled oscillatory system with two degrees of freedom, the parts of which have their own damping means, is located between the weighbridge and the force-registering means. In one embodiment, the load on drawbar 1 is applied to lever 2 and thence through an elastic coupling 4 to a second lever 8 operating the weighing head 7 through a drawbar 10. The lever 2 is provided with damping means 3 and the lever 8 and head 7 are controlled by the damping means in the latter. The natural frequencies of the two parts of the system are suitably adjusted by adjustment of the damping devices, the spring constant of the coupling 4 and weights such as 9 on lever 8. In another embodiment the drawbar 5 is connected -directly to the weighing head 7 and carries a weight thereon, Fig. 1 (not shown).

Abstract: 1276999 Cutters NOVA HUT KLEMENTA GOTTWALDA NARODNI PODNIK 19 April 1971 [27 Jan 1970] 23016/71 Heading B3C [Also in Division F2] A device for removing protuberances from the internal surface of a tube comprises two tool holders 4, 10 (Fig. 3) pivotally mounted on an elongate body 3. Springs 7, 11 bias the tool holders towards the wall of the tube (not shown) and the extent of such movement is adjusted by set screws 8, 12. The device is guided in the tube by spring-loaded guides 13 which also resist rotation of the tool within the tube. Tool holder 4 may carry a rotatable cutter 5 (Fig. 4) journalled about an axis inclined at between 30 and 60 degrees to the plane of pivoting of said tool holder 4. Alternatively, for use with tubes of finite length a front roughing cutter may be mounted on holder 4. A chipping tool 9 is rotatably mounted on holder 10 and encounters the protuberances prior to the cutting tool thereby breaking them down to discontinuous chips which are more easily removed. The device is held by bar 15 by which it may be axially rotated through an angle limited by the abutment of guides 13 with the protuberance to be removed. The tool is particularly suited to removing the internal flash from longitudinally welded tubes after their manufacture.

[Class 100 (ii)] A solution of a substance containing a polyacrylic compound is employed in the preparation of a metal planographic plate or as a dampening fluid during printing. The compound, which must be in water-soluble or water dispersible form, may be polyacrylic acid, methyl-acrylic acid, or a salt thereof, preferably the ammonium salt. The pH value of the solution may be controlled by neutralizing, and if desired the solution can be rendered alkaline to a value of pH8. A water-soluble salt of phosphoric or chromic acid may be added when the solution is to be employed in dampening; when printing with excessively greasy inks, a mild organic acid such as gluconic acid or a mixture thereof with glucono lactones and pyruvic or levulinic acid, is added to prevent formation of scum. For treating the plate preparatory to printing, a solution of from 2-5 per cent by weight can be used and for dampening a solution of À04-À10 per cent is employed ; an approximately equal amount of organic acid or one-tenth of the amount of a salt of phosphoric or chromic acid may be added.
