Abstract: 962,203. Colour television. FERNSEH G.m.b.H. Jan. 25, 1963 [Jan. 27, 1962], No. 3211/63. Heading H4F. In a vecterscope apparatus for use with colour television signals, a plurality (two as illustrated) of N.T.S.C.-type subcarrier signals are applied in cyclic succession via gate stages 9, 10 controlled by a gatepulse generator 19 to a pair of synchronous detectors 14, 15 whose outputs are applied to deflect a cathode-ray tube 18, the arrangement being characterized by means to apply the reference subearrier oscillation 21 (derived if desired from a subcarrier synchronizing " burst ") to the synchronous detectors via separate channels controlled by gates 23, 26 in synchronism with the operation of gates 9, 10, an adjustable phase shifter 24 being included in one channel which may be adjusted to allow for any phase displacement between the signals applied to gates 9 and 10. The invention is of use where it is desired to compare a reference signal with the same signal after passage through apparatus under test where it may be subject to delay. By appropriate adjustment of phase shifter 24 the reference subcarrier oscillation may be subjected to the same delay, whereby in the resulting cathode-ray display Fig. 4, the traces due to the reference and test subcarrier are in rotational alignment and may be compared more readily. Gate-pulse generator 19 may control a blanking stage 31 to suppress the cathode-ray beam during change-over from one subcarrier signal to another.

Filed: 1959-01-29
Abstract: 853,049. Process cameras. POWERS CHEMCO Inc. Jan. 29, 1959 [March 31, 1958], No. 3275/59. Class 98(1) In a process camera having a half-tone screen storage compartment to one side of the camera back, each screen is attached to a carrying frame by a parallel motion linkage which is actuable from outside the camera, when the frame has been guided from the storage compartment into the camera, to position the screen correctly with respect to the focal plane of the camera. As shown, two carrier frames 36, 38 are guided on straight rails 44, 48 into and out of the storage compartment (Fig. 2, not shown) by means of flanged wheels 40 and rollers 42 engaging inverted U-section guides 46, 49. A dog-clutch operated by handle 86 through a spring toggle arrangement (Figs. 6, 16 and 17, not shown) is provided to engage handle 66 with one or other of two chain drives to move either of frames 36, 38 along rail 44 or 48. Half-tone screens 34 and 35 are attached to frames 36 and 38 by means of links 98 and 100 and further parallel motion links (Figs. 3 and 4, not shown) are provided to bear the weight of the screens. On moving either frame along its rail toward the camera, the shaft carrying the links 100 is connected with one of two shafts (Figs. 8 and 9, not shown) controlled by handle 138. On turning handle 138 these shafts are rotated through a resilient connection and links 100 are thus turned to urge the screen 34 into resilient engagement with locating stops (Fig. 10, not shown) carried on brackets such as 174. Crank arms and connecting rods (Figs. 3 and 4, not shown) impart this turning movement to links 98 and handle 138 is retained against the force of the resilient connection by a spring lock. The position of the screen locating stops is indicated on dial 222 and the brackets 174 are adjustable in the direction of the optical axis by means of handle 208. Screwthreads on two vertical shafts 192 engage four worm-wheels on screw-threaded shafts 186 simultaneously to move four brackets 174 and the shafts .192 have pinions 206 meshing with pinions fixed on a horizontal shaft (Fig. 10, not shown). In addition, the storage compartment mav contain a ground-glass focusing plate which may be slid into the camera and a vacuum film support may be moved into the storage compartment when the focusing plate is in use Specification 751,763 is referred to.

Title: Process for bleaching bast fibres, especially flax, hemp and the like
IPC: D06L4/75
Filed: 1931-02-02
Abstract: Bast fibres, especially flax, hemp and the like, are quarterto half-bleached and freed from lignin constituents by a process comprising four stages, viz. (1) a bowking in sodium carbonate solution; (2) a treatment in a bath containing hypochlorous acid with sufficient hydrochloric acid to generate free chlorine and of an acidity corresponding to pH < 5; (3) a washing by infusion with sodium carbonate or similar alkaline solution, and (4) a treatment in an alkaline or neutral hypochlorite bath.  The bowking is effected by boiling for 2 to 3 hours in a solution containing 4 to 9 grams. of sodium carbonate per litre.  If the desired bleach is not obtained in the alkaline or neutral hypochlorite bath, this bath may subsequently be slightly acidified, e.g. with hydrochloric acid [repetition of stage (2)] whereafter the fibres are preferably again infused with a weak solution of sodium carbonate [repetition of stage (3)]. The several stages of treatment may be effected under pressure or in vacuo or in circulating or non-circulating bath liquors. Specification 157,840, [Class 15 (i), Dyeing &c., Apparatus for], is referred to.
