Abstract: Polyvinyl chloride resins and copolymers thereof are produced containing little or no get content, commonly referred to as "fisheyes", even after numerous charges to a reaction vessel without cleaning thereof between charges. A primary dispersant system such as a high hydrolyzed polyvinyl acetate and an optional modified cellulose ether are utilized in associated with a low hydrolyzed secondary dispersant, for example, polyvinyl acetate, in the reaction vessel such as a polymerizer containing an aromatic inhibitor polymer build-up compound coated on the internal walls thereof. The resin particles produced tend to have a uniform particle size and a high porosity so that plasticizers can readily be incorporated therein. Such contamination buildup on the reaction vessel walls is reduced or prevented, the amount of gel is reduced and production rate is increased since, as noted above, cleaning of the vessels is not required.

Abstract: Alkali hydroxide, chlorine and hydrogen are produced from an aqueous alkali chloride solution by membrane electrolysis. A high-NaCl solid salt, which contains impurities, is dissolved in water in a salt dissolver. Precipitating chemicals are added to the salt solution to precipitate the impurities. The resulting mixture is fed to a thickener, from which precipitates and clarified raw brine are separately withdrawn. The clarified raw brine from the thickener is divided at a ratio between 2:1 and 20:1 into first and second partial streams. The larger first partial stream is mixed with the salt solution and the precipitating chemicals before entering the thickener and the resulting mixture is fed to the thickener. The second partial stream of the clarified raw brine is fed through a fine purifier to the electrolytic cell. Spent brine from the electrolytic cell is fed to the salt dissolver.

Abstract: Pilot workload is reduced in a helicopter having a force-type, multi-axis sidearm control stick by providing a displacement-type control stick for collective blade pitch control. Either stick may be used by the pilot. When the force-type stick is employed, a trim system causes the displacement-stick to track a collective position command signal which is provided to the blade actuators. Changeover of control to the displacement-type control stick is accomplished either with a switch, or by moving the collective-type control stick. The signals associated with each control stick are alternately faded in and out to assure a smooth transition when collective control is switched over from one to the other.

Abstract: In a nonvolatile semiconductor memory according to the invention, a power source voltage of 5 V used in a ordinary read mode is applied to a read line (RL) in the data read mode without changing its value. If a write line (WL), a selection gate line (SG), a control gate line (CG), and a read line (RL) are respectively set at 0 V, 5 V, 0 V, and 5 V in the data read mode, the poten­tial at an n-type diffusion layer (12) becomes 0 V. In this case, the potential at the control gate line (CG) is 0 V, and the potential at a floating gate electrode (16) becomes substantially 0 V. That is, an electric field is not applied to a thin insulating film (17) located between the floating gate electrode (16) and the n-type diffusion layer (12). As a result, electron injection and discharge due to the tunnel effect do not occur.

Abstract: 2.1 In known electrical switching apparatuses, specific small contact plates are inserted at the contact points to prevent the contact point being damaged by burning away. This is very costly in material and production terms. In addition, dynamic opening of the contact point can occur as a result of the formation of current loops, even with relatively small short-circuit currents. 2.2 For electrical switching apparatuses which are to be switched when no current is flowing, a contact arrangement is to be specified which makes the use of small contact plates superfluous, which is suitable for the transmission of high short-circuit currents without unintentional opening of the contact point and which is of simple design in production and assembly terms. 2.3 The contact arrangement according to the invention has an angle-shaped fixed contact which covers a moving contact in the form of a roof and has two contact regions with the latter, which are formed by two touching edges of the moving contact piece. <IMAGE>
