Abstract: Graft polymers comprising a polysaccharide as the graft base and water-soluble, ethylenically unsaturated, carboxyl-containing monomers can be prepared by batchwise free-radical inverse suspension polymerisation. 
<??>If partial dewatering is carried out after the polymerisation and the products are then crosslinked using transverse crosslinking agents, graft polymers are obtained which have a very good absorption capacity and are further improved with respect to their absorption rate for water and body fluids and their fine-particle character.

Abstract: A metal is disclosed of degating clustered metal castings produced by ECP in which molten metal (27) is gravity poured into a dry, unbonded sand mold (9) for solidification, the mold containing a plurality of consumable foam patterns (17) interconnected by a complex centralized gating system (23). The method is improved by forcing purge air through the unbonded sand mold (9) just prior to the solidificatin of the core metal of the gating system (23), the purge air being forced into such mold at a predetermined pressure (such as 80-120 psi) and for a period of time (such as 10-20 seconds), causing the gating system (23) to disintegrate into pieces or beads (29) of metal. The elapsed period of time from the moment of pouring the molten metal into the mold to the moment at which the purge air is injected into the mold is critical and for certain metals is usually in the range of 3-5.7 minutes.

Abstract: The rotor in­cludes a top disk (T), a bottom disk (B) and a spacer belt (S) spac­ing the two disks apart to form a rotor assembly (A). Both disks are fabricated by overlying multi­ple layers of tape (14, 16, 18, 20) the tape being made from fibers held together with resin. The tapes are stacked in multiple layers normal to the spin axis of the rotor (30). When the tape is compiled in multiple layers to a thickness of the top and bottom disk, the tape is compressed between plates (P₁, P₂) and cured at a tem­perature well above the autoclave temperature of sterilization of the rotor. Thereafter, a spacer belt (S) consisting of a spirally wound resin impregnated fiber is placed to space the top and bottom disks apart. Thereafter, the assembly is wound by a peripheral belt (B) with resin impregnated high stiff­ness fiber, which is cured and shrinks during curing to exert hoop tension around the periphery of the rotor assembly.

Abstract: The explanations and descriptions contained in the present ad­ditional patent concern some improvements devised for the "op­tical-electronic system for determination of direction and speed of a vehicle by emission of an internal laser beam" for which two former patent applications, namely nr. 9/82810 A/84 of Sept. 19th 1984 and nr. 9/82809 A/86 of May 27th, 1986 we­re submitted by the same author, UGO Licinio (25, via Valdiri­vo, Trieste, Italy). The above-mentioned improvements are a series of structural changes of the optical system, similar to the one described in the two former patents, but resulting in a smaller size of the measuring instrument without any change in the performances reported in the two former descriptions. A proposal is also made to use such small-sized optical device contemporaneously for the detection and measurement of its possible rotations around the internal axis parallel to its straight motion. 
     By resorting to the Sagnac principle, therefore, the optical device used in order to determine the speed and direction of a vehicle in motion may thus include some performances as a la­ser gyroscope. A description is also made of further improve­ments of the optical device and the elctronic computer, achi­eved from a consequence of the Fitzgerald contraction princi­ple that makes equal the time duration of the two forward and back, consecutive travels of a beam running once parallel and once perpendicular to the motion of a body, as demonstrated by the Michelson-Morley experiment. A blocks electric diagram is also described, with the changes introduced in order to improve the computering system, taking into account the new   situations created by the various modifications aimed to ob­tain a possibility of measurements of straight speed and tran­sverse rotations speed, even though the measuring instrument is remaining static.

Abstract: Apparatus for the vacuum-assisted, countergravity casting of thin-walled metal parts includes a plurality of expendable casting molds (14) supported on a top side of a reusable drag slab. Each casting mold includes a mold cavity and a mold ingate passage extending from the mold cavity into registry with a respective underlying slab ingate passage that extends between the top side and a bottom side of the drag slab and that optionally includes a molten metal filter therein. When the bottom side of the drag slab is immersed in an underlying molten metal pool with the mold cavities evacuated, the molten metal (12) is drawn upwardly through each slab ingate passage and the molten metal filter therein and then through each mold ingate passage (44) registered therewith into each mold cavity. The molten metal filter (28) in each slab ingate passage (24) removes inclusion-forming impurities from the molten metal as it is drawn upwardly into each mold cavity. The presence of objectionable, non-metallic inclusions that can adversely affect part performance is thereby minimized in the thin-walled parts cast in the molds. The drag slab can be reused in the casting of successive sets of expendable casting molds.

Abstract: To carry out such a method, quite elaborate means (for example sampling oscilloscopes) have hitherto been required. The novel method is intended to provide reliable information on the transmission characteristics of an optical fibre with little expenditure. It consists in that, in a receiver, the pulses transmitted via the optical fibre (LWL) are continuously compared with a reference pulse which has at least approximately the shape of the transmitted pulses to be expected and that such a section, falling into the reference pulse window, of the received pulse sequence, which exhibits a measure of correspondence with the reference pulse which is above a predetermined threshold, is gated for the determination of the pulse changes. This method can be used for determining, for example, the dispersion, attenuation and transmission bandwidth of an optical fibre. <IMAGE>

Abstract: In a driver circuit of direct drive matrix type LCD panel, a quantity of ON-STATE cells (or OFF-STATE cells) displayed on the just previous scan electrode is counted and a quantity of ON-STATE cells (or OFF-STATE cells) to be displayed on a present scan electrode is also counted. A compensation voltage is generated according to a predetermined relation based on a difference of the two above-counted quantities, and is superposed onto drive voltages of unselected scan electrodes or of each of data electrodes, in a polarity that an undesirable spike voltage induced on unselected cell voltage is cancelled, in synchronization with selection of the present scan electrode. The compensation voltage may be generated according to a digital difference of the two quantities or to a change in an analog voltage representing the counted quantity. The above-described relation of the compen­sation voltage versus the counted quantity difference may be proportional or may be given with a predetermined specific relation to meet the panel characteristics. The compensation voltage may be a flat voltage during the period for selecting the single scan electrode or may be of a spike waveform. Amplitude of this spike is determined by the above-described predetermined relation. An irregular panel brightness caused from spike voltages induced from data electrode voltage application is cancelled.
