Title: Apparatus for facilitating the treatment of the surface of rotary bodies, in particular for producing or preparing printing cylinders by photo-mechanical methods
IPC: G03F7/18
Filed: 1951-08-10
Abstract: 694,616. Printing on rollers. SCHNEIDER & CIE, L. Aug. 10, 1951 [Aug. 12, 1950], No. 18915/51. Class 98 (ii). [Also in Groups XIII and XXXIV] Apparatus for preparing photo-mechanical printing rollers is characterized in that at least one end shaft 10 of the roller 11 is carried by two coaxially rotatable rings, one ring 13 being fixed and the other ring 12 being rotatable with the roller, and that one or each ring has at the face contacting the other at least one annular groove into which a pipe 20 opens through the stationary ring 13, and at least one pipe 19 opens through the rotatable ring 12, the pipe 19 being connected to the roller so that a fluid can be fed to or removed from the roller 11 by means of pipes 19, 20. In one form the stationary ring 13 is carried by a frame 15 and supports the ring 12, the bearing surfaces of the rings being tapered. One end of ring 12 has a screw-thread carrying a nut 24 bearing on the end surface of ring 13 and secured by a lock-nut 25. The end shaft 10 is secured in ring 12 by three set-screws, of which one is shown at 14. Two grooves 17, 18, of semi-circular crosssection, are formed in rings 12, 13 respectively, and enclose a toroidal space communicating with pipes 19, 20. Pipe 19 is connected to a flexible tube 22 terminating in a suction cup 26. When copy 28 is wrapped round the roller 11, the cup 26 is placed over a hole 27 in the copy, and by connecting a pump to pipe 20 air can be drawn from between the copy and the roller, causing close contact between them. The roller can be rotated for exposing its lightsensitive surface through the copy without disconnecting the pump or causing flexible tubes to wrap round the shaft. Several pipes 19 and tubes 22 may be used. Tube 22 may be connected to an opening in the end face of roller 11 so that liquid may be fed therein; the liquid may then be removed by a similar arrangement at the other end. If the bearing surfaces of the rings are not tapered, ridges may be formed in one ring to enter recesses in the other ring at the sides of the groove or grooves, the outer ring being made in two parts.

In a colour television receiver synchronous demodulator circuit for use with a quadrature modulated colour subcarrier of, for example, the N.T.S.C. type but in which one of the modulation axes is periodically (e.g. at line or frame rate) switched through 180 degrees for the purpose of reducing colour falsification due to phase errors, and wherein the demodulation axes are arranged not to be identical with the modulation axes, means are provided to switch the directions of the demodulation axes synchronously with the switching of the modulation axis so that the angular relationship between the respective demodulation axes and the modulation axis which is not switched is maintained but the sign of the relationship is reversed. Figs. 5 and 6 illustrate the operation where the modulation I axis is periodically reversed and demodulation is effected along the R-Y and B-Y axes. The R-Y demodulation axis is switched through 246 degrees and the B-Y axis through 66 degrees. Fig. 7 (not shown) illustrates the operation when the Q modulation axis is switched through 180 degrees. Figs. 8 and 9 illustrate the operation when the Q modulation axis is switched and demodulation is effected along the X and Z axes (see " Colour Television" by Carut and Townsend, pages 241-248). Similar operation (not illustrated) applies when the I axis is switched.

Title: Manufacture of organic bases
Filed: 1931-07-04
Abstract: Organic bases are produced by condensing ammonia with unsubstituted dihalogenhydrins of polyhydric alcohols which have no side chain, the temperature during the reaction and isolation of the product being kept below 100 DEG  C.  The ammonia may be used in gaseous form, or water or an organic liquid may be used as a solvent.  The products are suitable for synthetic reactions and for medical and cosmetic purposes.  In examples (1) ammonia in absolute alcohol is added to a -dichlorhydrin and kept at 18 DEG  C. for 10 days; ammonium chloride crystals are removed, and the solution is evaporated under reduced pressure at 30-35 DEG  C.; the product may be purified (a) by distilling off unchanged dichlorhydrin by heating under reduced pressure at 70-80 DEG  C. or (b) by kneading with ether until the ether yields no residue on evaporation, when the product is dried under reduced pressure at room temperature, or (c) the reaction mixture without being freed from alcohol and ammonia is added drop by drop to a large excess of ether, and the doughy mass precipitated is separated from the mother liquor, kneaded with ether, and dried under reduced pressure; or (d) the product after the removal of alcohol and ammonia or after the removal also of unchanged chlorhydrin is dissolved in a small quantity of water cooled to 8 DEG  C. and precipitated with sodium carbonate as an oily mass; (12) dry gaseous ammonia is introduced into a -dichlorhydrin at -- 10 DEG  C., and the mixture is allowed to stand at 16 DEG  C. for 3-5 days, crystals of ammonium chloride being then removed; (13) gaseous ammonia is admitted on a number of successive days to a quantity of a -dichlorhydrin.  Instead of a -dichlorhydrin, b -dichlorhydrin may be used, or dibrom- or diiodohydrins. Erythrite dichlorhydrin and mannite dichlorhydrin are also mentioned as suitable.  The products usually contain nitrogen, halogen and oxygen.

Adjustments are described for dry shavers having reciprocating, rotating or oscillating cutting members. As shown in Fig. 1 the apertured cutting plate 2 is provided with an apertured cap 4 which is removable to increase the amount by which the skin 5 penetrates into the apertures 1. In Fig. 6 the size of the apertures 1 is decreased by screwing the nut 19 to compress the rubber washers 18a. Further modifications describe similar adjustments in circular cutting plates.

Examining relative position of sighting lines of telescopes simultaneously.-When telescopes are disposed on a common carrier having an oscillating support, simultaneous examination of the sighting-lens is effected by releasing simultaneously an optical signal lying in the path of the rays at the appearance of which the position is ascertained in each telescope of a common target. This may be recorded by cameras at each telescope, the release of the shutter replacing the optical signal; or a shuttered search-light may be used as the common target. The optical signal may comprise a glow-lamp disposed in front of the objective so that it projects into the field of vision, or so that it illuminates the sighting-mark of the telescopes.
