Abstract: PRODUCTION OF LOW-SULFUR CHROMIUM (III) OXIDE PIGMENT                              Abstract In the continuous production of low-sulfur chromium(III)oxide pigment comprising the steps of reducing a finely divided alkali metal chromate in a heated hydrogen-containing reaction zone at a temperature of about 900 to 1600°C, and precipitating the resulting chromium(III)oxide in the form of an aqueous dispersion, the improvement which comprises passing the reduction products from the reaction zone to a dwell zone and generating heat within said dwell zone to maintain the temperature therein in the range of about 900°C to 1600°C.          Preferably the dwell zone temperature is within 200°C of that in the reaction zone and is maintained by introducing excess hydrogen into the reaction zone and consuming it in the dwell zone by introduction of oxygen.  The resulting pigments exhibit a fuller green color.

Abstract: Specification Title of the Invention Magnetic recording and reproducing apparatus Abstract of the Disclosure A tape recorder of the auto-reverse system wherein all the tape drives including the constant-speed drive of a tape, the rapid drive thereof, the change-over between the normal and reverse drives, etc. are executed by means of a single capstan employing a single motor as its drive source, and wherein all the reel rest drives including the constant-speed drives of reel rests, the rapid drive thereof, the change-over between the normal and reverse drives, etc. to be made following the tape drives by the capstan are executed by means of a single idler employing the single motor as its drive source.  All the tape controls are achieved by the use of the single capstan, the single idler and the single motor.  More specifically, the change of the directions of rotation of the single idler and capstan, i.e., the inversion of the tape drive is effected by the normal -reverse change-over of the single motor, the operation of alter-nately bringing the single idler into engagement with or dis-engagement from the reel rests is attained by the turning force of the normal - reverse change-over of the motor, and the change-over of the speeds of rotation of the single capstan as well as the single idler is accomplished by two-stage change-over speeds of the single motor.  Thus, with the single motor, the one idler and the one capstan which employ it as the drive source are controlled to the constant-speed rotation or the rapid rotation, and besides, the change-over of the directions of rotation is possible.  Further, this invention provides an electric circuit system for perfectly putting such mechanism into practical use.     The electric circuit system includes a circuit which holds the motor at the predetermined constant-speed rotation and thereby effects the constant-speed feed of the tape, a circuit which reliably controls the normal and reverse rotations of the motor in response to a tape inversion command signal, a circuit which changes-over the motor from the constant-speed rotation to the high-speed rotation and thereby controls the rewinding and the fast feed of the tape.  Owing to the development of the electric circuit system based on such peculiar control method and to the combination between this electric circuit system and the mechanism stated above, the auto-reverse type magnetic recording and re-producing apparatus of the one-capstan and one-idler system is realized.     -1a-

Abstract: Abstract of the Disclosure Spoken message transmission devices are known which use a recording support (disc or tape) which moves with respect to a read head.  Such devices are used in telephone exchanges to transmit short-duration messages to sub-scribers but, because of intensive use, are subject to wear of the read head so that the message becomes unintelligible.  To overcome this disadvantage the present invention uses a digital memory containing a sequence of digital samples each stored in relation to an address and representing the message. An addressing device addresses the digital memory to produce a series of address codes so that the sequence of samples is obtained on the memory out-put.  The samples are fed to a transducer having a digital-to-analogue converter which converts them into signals suitable for an ear-piece.

Abstract: ABSTRACT OF THE DISCLOSURE         Pressed fiberboard  is produced in an S-1-S type process at much shorter than normal (prior art) press cycles.  The process includes the use of fiber furnish having preselected shrinkage characteristics.  This furnish is wet formed into a mat either with or without a paper overlay, which overlay may be decorated or undecorated, depending on the desired end use and pressed wet as in the 5-1-8 process, using control means, such as stop bars in the hot press, to limit the final separation distance between the hot plates in each press opening to provide full caliper reduced density board.  By using a fiber furnish having selected shrinkage characteristics it has been found that the pressed board can be safely removed from the press in a semi-cured, moist condition, at unusually short press cycles.  The use of said fiber furnish also permits the use of higher than normal (prior art) press temperatures without incurring discolouration of the paper overlays. The board is then baked and humidified to complete the curing process.

Abstract: IMPROVEMENT IN OR RELATING TO METHOD OF OF CONTINUOUS       SLITTING OF FLAT MATERIAL AND APPARATUS THEREFORE      ABSTRACT OF THE DISCLOSURE           A method and apparatus for continuous cold cutting or slitting of a flat material wherein the flat material is subjected to a first step of partial-shearing or penetration in a zigzag state to a controlled depth of penetration, and subsequently to a second step of flattening, thus forcing the penetration formed in the material back to substantially the original thickness of the material, thereby to perform complete severing or slitting the material having no burrs formed during the operation.  The first working action is obtained from feeding of the flat material into the controlled spacing of opposing pairs of cutter discs so that there occurs partially shearing or penetration in the flat material under an optimally predetermined interfering action by the opposing pairs of cutter discs into the material when it engages therewith.  The second working action is obtained from the insertion of thus partially-sheared or penetrated material into the spacing optimally predetermined between an opposing pair of rolls having a flat cylindrical surface so that there occurs flatten-ing action by the opposing pair of rolls over the both surfaces of the material when engaged therewith.  The cutter discs and flattening rolls are controllably driven in synchronism.

In  one embodiment of the switches, a closed glass capillary tube contains a pair of aligned nickel wires with ends selectively contacted simultaneously by a mercury piston or globule providing a circuit-closing position for the switch.  The switch is set in the circuit-closing position by applying heat to a non-oxidizing gas within one end of the capillary tube.  The switch is then reset to a circuit-opening position at any desired time by applying heat to a non-oxidizing gas within the other end of the capillary tube.  The non-oxidizing gas is heated by electrothermal means disposed at each end of and within the ends of the capillary tube.  A barrier such as a collar disposed near the end of each of the wires is provided to prevent the mercury piston or globule from separating into a plurality of globules upon application of strong forces to the globule from either end of the tube.
