Title: Process for the preparation of an impact-resistant thermoplastic resin
IPC: C08F279/02
Filed: 1988-08-16
Granted: 1992-04-15
Abstract: In a first stage of this process, an elastomer latex is prepared in aqueous emulsion in the presence of a nonionic surface-active agent, from at least one ethylenically unsaturated monomer; then, in a second stage, at least one vinyl monomer, insoluble in water or poorly soluble in water, is added to the latex thus obtained. According to the invention, in the second stage at least one polymer or copolymer based on carboxylic acid units and capable of forming an interpolymer complex with the nonionic surface-active agent employed in the first stage is added, and then the pH of the mixture is lowered sufficiently to produce the transfer of the particles of the said latex into the said vinyl monomer(s); and, in a third stage, a suspension or bulk polymerisation is performed on the phase consisting of the said monomer(s) from the second stage and containing the transferred latex particles.

Abstract: The cross belt device is fitted around a tire of an automobile, which is to travel on a snow-covered road, to prevent the tire from slipping. In a cross belt device (1), an outer ring (4) is supported rotatably on an inner ring (3) secured detachably to a wheel (2) of an automobile, and a number of elastically deformable leaf springs (7) are attached radially to this outer ring, cross belts (8) extending across a tread surface (12a) of a tire being connected at one end of each thereof to the outer end portions of the leaf springs and at the other ends thereof to an endless outer circumferential strap (9). The cross belts are adapted to be turned from the positions on the tread surface to the positions away from the tread surface, and vice versa by utilising the elastic deformation of the leaf springs. When the diameter of the tire varies due to the flexure of the ground-contacting portion thereof occurring while the automobile runs on a road, or, when the cross belts are displaced on the tread surface in the circumferential direction while the automobile runs, the variation of the diameter and the displacement of the cross belts are offset by the elastic deformation of the leaf springs and the rotation of the outer ring.

Abstract: The rotating and alternating piston machine is an alternating or free piston machine in which the pistons effect a rotating and alternating movement. Main characteristics: 1) the use of rotation or alternation/rotation, for example in order to control the ports provided in the cylinder walls of two- and four-stroke engines, pumps and compressors; 2) simple conversion of rotating and alternating movement by mechanical or electrical means. The rotating and alternating piston machine offers the possibility of: pumps, including the electric drive, in which there is only one rotating part; direct conversion of the alternating movement of the piston into electrical energy; control of the gas movement by the piston; operation of other ports having specific functions (for example, introducing additional compressed gas, discharge ports operating in succession etc.); free selection of the number of piston strokes per rotation; choice of piston stroke kinematics; powerful rotation or swirling of charge; easily designed compact and inexpensive machines; possible integration of a compressor without having to provide for an additional volume and virtually without any weight increase. In the two-stroke combustion engine, in which the gas exchange is controlled by the pistons (2 and 5), the useful power is available at the central shaft (14), which carries the rotating and alternating piston (2) in a longitudinally-slidable but rotationally-fixed manner. Movement is converted by the oscillating shaft (35) and transmission element (38). The engine is provided with four working chambers and has a 100% mass balance.

Abstract: A semiconductor memory device having a self-correcting function comprises a plurality of non-volatile memory cells (2) and first and second read circuits (5, 6) for reading bit data from the memory cells. Part of the memory cells (1a) store data, whereas another part (1b) store parity bits on the data. Each memory cell (2) selectively stores "0" or "1" by causing itself to be charged with an electric charge. The first and second read circuits (5, 6) receive a plurality of bit data from a plurality of selected memory cells in order to output correct data with correct parity. The criteria of detecting "0" and "1" in the first and second read circuits (5, 6) are set to different values, so that the first read circuit (5) detects a current value smaller than the value of the current flowing through the memory cell holding a bit error because of charge depletion, whereas the second read circuit (6) detects a current value greater than that value. Consequently, even if the variation of the threshold resulting from the charge depletion allows the presence of a faulty memory cell therein, one of the read circuits (5, 6) can make correct data read.
