Abstract: ABSTRACT OF THE DISCLOSURE          A process for the preparation of 2-mercaptobenzothiazole is disclosed.  The process comprises heating a reaction mixture comprising nitrosobenzene, hydrogen sulfide and carbon disulfide in a molar ratio of about 1:1.5 to 4:1 to 3, respectively, to a temperature from about 200 to about 300°C, fc. a time sufficient to convert at least a portion of the reactants into 2-mercaptoben-zothiazole.  In an alternative process, there is first reacted nitrosobenzene with hydrogen sulfide in a molar ratio of about 1:1.5 to 4, at a temperature from about 20 to about 100°C for a period of time sufficient to substantially reduce the nitrosoben-zene, and subsequently reacting the resulting product mixture with from about 1 to about 3 mole equivalents of carbon disulfide per mole of originally charged nitrosobenzene, at a temperature from about 200°C to about 300°C.

Abstract: ABSTRACT OF THE DISCLOSURE The invention is a vertical-axle windmill (or hydromill) which rotates irrespective of wind direction. The windmill is provided with a plurality of turnable sails, which automatically pivot toward the optimum leeway, to catch favourable wind, to produce torque to nearly three quarters of each rotation, and to avoid the headwind with the least possible resistance through the remaining quarter of its rotation, thus efficiently converting wind force to mechanical power.

Abstract: OPTICAL DETECTOR     ABSTRACT OF THE DISCLOSURE       The optical detector is particularly adapted for use with an apparatus for separating blood into its components and is of the type including a centrifuge for centrifuging whole blood to separate same into the components thereof and of the type where-in plasma is withdrawn from the centrifuge through a flexible, light transmitting tubing and the spillover of red blood cells into the plasma withdrawn is monitored by the optical detector.          The optical detector comprises a block having a slot across the top face thereof, the inner portion of the slot having a width less than the outer diameter of the tubing which is received in the slot such that when the tubing is pressed into the slot, it is squeezed from a circular cross section to an oval cross sec-tion to present two flat portions of the tubing adjacent oppo-site sidewalls of the slot.  A first cavity is situated in the block behind a first sidewall of the slot and a second cavity is situated in the block behind a second sidewall of the slot.    Apertures are provided in the sidewalls and light from a light source is directed along the axis of the apertures, through len-ses in the cavities which seal the cavities from the slot and through the tubing in the slot from the first cavity to the sec-ond cavity where a photosensor is located. The photosensor is operable to generate an electrical signal which is indicative of the light sensed and which can be utilized for measuring the optical density of the plasma flowing through the tubing.

Abstract: W.G. Bartholomay-G.W. Couturier-S.Ghosh-M.Winn - 2-2-2-2 TEST ARRANGEMENT FOR COMMUNICATION PATHS IN TIME-DIVISION MULTIPLEXED SWITCHING SYSTEMS            ABSTRACT OF THE DISCLOSURE:         An arrangement is described for testing a communi-cation path to a 2-wire analog line through a time-division multiplexed  switching  system,  wherein each  analog  line is coupled  to  the  system by  a  hybrid  circuit  which provide separate transmit and receive paths.  A digital tone source is coupled to a time-division bus of the system such that the digital tone source transmits signals toward the line on the receive path.   A ring  relay associated with  the  line  is operated  to produce an open circuit condition between the hybrid circuit and the line.   The open circuit alters the transhybrid loss of the hybrid circuit such that the signals on the receive path are reflected back toward the time-divi-sion bus on the transmit path.   A digital tone detector is coupled to the transmit path such that the reflected signals may be detected.

Abstract: Abstract of the Disclosure A dot matrix printer having a reciprocating hammer bank prints characters in either a standard or a compressed size using one of two different sets of modulation bits stored in a character generator for each character.  A control code byte preceding each line of characters to be printed selects the sets of modulation bits in the character generator to be used and in addition selects the repetitive counts to be made by two different decoders in response to timing pulses desig-nating the different dot column positions during each sweep of the hammer bank to control the application of the modulation bits from the character generator to actuating mechanisms for the hammers within the hammer bank.  The compressed characters are the same height as but of reduced width compared to the standard characters, with the result that each hammer in the hammer bank prints a greater number of compressed characters than standard characters while bidirectionally reciprocating through a fixed distance relative to a paper or other printable medium.

They have units of the general formula (M)x(T')y, wherein M represents an R3SiO0.5 unit in which R is a monovalent hydrocarbon radical or a halogena-ted monovalent hydrocarbon radical having from l to 18 carbon atoms, T' represents a unit of the formula (R"S) R'SiO1.5 in which R' is a divalent, trivalent or tetravalent hydrocarbon radical having at least one-C-S-C-group, R" is hydrogen or R, x and y each represent a number greater than 1 and up to 20,000, in which the ratio of x to y may vary from 1:0.33 to 0.005:1 and z is 1, 2 or 3.  These sulfur-containing polysiloxane polymers are prepared by reacting, in the presence of an acid catalyst having a pKa value less than 1.0, a mixture containing (1) a hexaorganodisiloxane and (2) a silicon compound having the formula (R"S)zR'Si(OR)3, in which R, R' and R" are the same as above.  These polymers are useful as cross-linking agents in free radical polymerizations.  They are more compatible with organic compounds than prior art polysiloxanes.
