Abstract: 191,736. Roucka, E. Jan. 12, 1922, [Convention date]. Recording by co-ordinates; damping-arrangements for recording-apparatus.-Relates to apparatus in which indicating and recording members are moved periodically to positions corresponding to the instantaneous positions of a distant pointer. As shown in Figs. 1 - - 5, an arm 4 is continuously oscillated by a cam 8 between a member 42 on a lever 62, and members 46, 47 forming part of U-shaped members pivoted at 48. The lever 62 is normally held by a detent 80, Fig. 3, against the action of a spring 66, but is released when an impulse is received by magnet 38 due to the arm 20, which is rotated synchronously with the cam 8, making contact with the pointer 26 of an indicating instrument at the transmitter. The arm 62 is subsequently restored by a cam 72. The members 46, 47 are shaped as shown in Fig. 5 so that according to the position of the arm 4 when the impulse is received, one or other of them will be engaged by the part 44 on arm 4 and will be raised thereby. One of the extensions 50, 52 will therefore be depressed to rock the arm 56 about its pivot 54. The arm 56 carries a projection 61 secured to an arm 90, pivoted at 92, by a link 96 and spring 94. Movements of the arm 90 are communicated to a recording arm 102, Fig. 4, by means of a shaft 116, connected to the arms 90, 102 by spiral springs 124. 122 respectively. A magnet 100 is provided to check oscillations of the arm 102.

Abstract: PCT No. PCT/EP88/00407 Sec. 371 Date Jan. 6, 1989 Sec. 102(e) Date Jan. 6, 1989 PCT Filed May 10, 1988 PCT Pub. No. WO88/09481 PCT Pub. Date Dec. 1, 1988.When signals from an incremental transmitter are being evaluated, noise may distort the signals and the subsequent stages connected to the transmitter may therefore be incorrectly controlled. The invention discloses a process for suppressing the noise, thereby permitting correct evaluation. In the process, the signals at the outputs of the incremental transmitter are sampled at high frequency and stored in an intermediate store. They are then checked to ascertain whether a predetermined sequence of output signals exists. Since this predetermined sequence is not respected in the event of interferences, no signal is produced. A signal is produced only when the predetermined sequence is respected. The process can be applied wherever it is desired to obtain an undistorted output signal using an incremental transmitter of simple design.

Filed: 1994-08-18
Abstract: Sequential charging of initiator and monomers in a multistage solution polymerization process involving conjugated diene and monovinylaromatic monomers wherein the initial and final charges are monovinylaromatic monomer results in the production of polymodal linear block copolymers with terminal resinous blocks. A typical 6-stage charge sequence is as follows: stage 1: (Si); stage 2: (Si); stage 3: (B); stage 4: (Si); stage 5: (B) and stage 6: (S) wherein (Si) is monovinylaromatic monomer and initiator, (B) is conjugated diene monomer and (S) is monovinylaromatic monomer. At each stage, polymerization is allowed to continue until no free monomer is present. The polymodal block copolymer products comprise high, medium and low molecular weight species designated, respectively, as S1-S2-B1-S3-B2-S4; S2-B1-S3-B2-S4; and S3-B2-S4 wherein S1, S2, S3 and S4 represent, respectively, polyvinylaromatic blocks resulting from polymerization of the first, second, third and fourth charges of monovinylaromatic monomer (stages 1,2,4 and 6); B1 represents a polydiene block resulting from polymerization of the first charge of conjugated diene monomer (stage 3); and B2 represents a polydiene block resulting from polymerization of the second charge of conjugated diene monomer (stage 5). The subject copolymers can be fabricated into sheets and molded objects possessing little color, a high degree of transparency and excellent impact resistance. These fabricated products do not craze on being impacted.
