Filed: 1996-01-18
Abstract: An output signal of a magnetoelectrical transducer of a capstan DC motor used in a magnetic tape recorder includes a DC offset voltage. The output signal of the transducer is coupled to a non-inverting input of a first operational amplifier. The output signal is also coupled to an inverting input of a second operational amplifier, operating as a comparator. The non-inverting input of the second operational amplifier is coupled to an output terminal of the first operational amplifier that amplifies an AC voltage component of the transducer output signal. By means of two anti-parallel coupled diodes in a negative feedback branch of the first operational amplifier, a DC amplification of unity is obtained as soon as a first peak of the output signal of the transducer is reached.

Abstract: 592,093. Fluid-pressure servomotorcontrol systems ; valves. OLIVER, A. G. Jan. 4, 1945, No. 377. [Class 135] A governing device for fluid-pressure systems comprises an apertured sleeve connected at one end to a fluid-pressure system and at the other to an exhaust system, variations in pressure in the fluid-pressure syntom moving a valve member axially within the sleeve so that the aperture or apertures on one side of the valve member are closed whilst those on the other side are opened whereby the pressure in a housing surrounding the sleeve and communicating with a fluid pressure operated regulating unit is varied to effect movement of the unit. As shown, the governing device comprises a control unit, Fig. 1, and a regulating unit. Fig. 2. The control unit comprises a housing 1 in which a sleeve 2 is held by a bush 3 and a union nut 7. A ball 9 moves with slight clearance in the sleeve 2 and is pressed towards the union nut 7 by a spring 11 adjustable by a non- rotatable screwed spindle 14 moved axially by a nut 18. The nut is rotated by a handle 19 and prevented from moving axially by a flanged nut 17 screwed on to an extension 15 of the housing 1. An annular space 4 between the housing 1 and the sleeve 2 communicates with the interior of the sleeve by a slot 8. Besides the union nut 7, the housing has a connection 20 to the regulating unit, two diametrically opposite connections 21 serving as to a pressure gauge or to another regulating unit, and a connection 23 to atmosphere or to an exhaust or system or to the suction side of a pump. The regulating unit comprises a spring-loaded piston 26 moving in a cylinder 25. The latter has a connection 30 joined to the connection 20 of the control unit by a pipe 22, and a connection 31 to atmosphere or the suction side of the pump. The two sides of the piston may be connected by an adjustable byepass valve 32 having a head portion notched on one side to connect. passages 33, 34. The piston rod may be connected by a coupling 29 to a balanced steam throttle valve or to the electric starter for a pump or to a reducing valve. In operation, the spring-loaded ball 9 moves under the influence of the controlling pressure over the slot 8 creating a greater or less pressure in the space 4 and hence in the operating cylinder the piston of which consequently regulates the steam valve or other means governing the pressure system. The slot 8 may be replaced by a series of small holes arranges spirally around the sleeve where the controlling fluid is a gas or a light liquid. Where the pressure in the system is too low to operate the control unit, the latter may be operated by the pressure of a small pump driven by an engine or from the shaft of a low pressure fan or water circulator in the system. A smaller control unit may be installed as a relay between the operating unit and the main control unit. The control units of several dispersed regulating units may be grouped together in one place.

Title: Propylene sulfide polymers and method of making the same
IPC: C08G75/08
Filed: 1963-01-07
Abstract: Propylene sulfide is polymerized or copolymerized with 3 to 20% by weight of total monomer of an unsaturated aliphatic vicinal episulfide cross-linking agent, the reaction being carried out in an environment substantially free from elemental oxygen and unreacted water in the presence of a catalyst which is the reaction product of diethyl zinc and water or diethyl zinc and hydrogen sulfide. The cross-linking agent may be allylthioglycidyl ether; also referred to are vinyl cyclohexene episulfide and butadiene monoepisulfide. The polymerization may be carried out at temperatures of 20 DEG  to 60 DEG C., with or without an inert solvent, for example an aromatic or aliphatic hydrocarbon or chlorinated hydrocarbon. The catalyst is used in amounts from 0.05 to 3% w/w on total monomer, and may be the reaction product of 1 mol of water with 1-3 mols of diethyl zinc or of 1 mol of diethyl zinc with from 0.05 to 1.2 mols of hydrogen sulfide.ALSO:A polymerization catalyst is a reaction product of diethyl zinc and water or diethyl zinc and hydrogen sulfide.  The diethyl zinc-water catalyst may be prepared by mixing the dialkyl and water in molar ratio 1:1 to 3:1 in an inert hydrocarbon solvent e.g. benzene or hexane.  The molar ratio of diethyl zinc to hydrogen sulfide may be 1:0.5 to 1:1.2.  The dialkyl may be dissolved in an inert hydrocarbon solvent and hydrogen sulfide gas bubbled through the solution, or a standard saturated solution of hydrogen sulfide can be mixed in predetermined proportions with a standard solution of diethyl zinc in a hydrocarbon solvent.  Both catalysts should be prepared in an environment substantially free from elemental oxygen and water other than that used in forming the catalyst.
