Title: Method of scanning pictures or the like by means of braun tubes having a screen showing persistence of afterglow
IPC: H04N5/257
Filed: 1936-02-06
Abstract: 469,907. Television. MICHAELIS, E. (Kinne, E.) Feb. 6, 1936, No. 3623. [Classes 40 (iii) and 40 (v)] To obviate the effects of afterglow when scanning by a cathode-ray tube K, a relay A or a second cathode-ray tube K2, which is relatively displaced by one element of the picture, produce picture voltages, which differ from those due to the scanning-tube by a voltage corresponding to the brightness of the element being scanned, and signals are obtained corresponding to this difference. The photo-electric currents from the cell F are applied to the grid of a valve J, which is biassed beyond cut-off. The operating point on the characteristic curve is moved to the emission range by periodic impulses at Q immediately before the completion of the scanning of each element of the picture. Voltages, which accumulate on condensers E, C, discharge through resistances G1, R with a curve proportional to the decrement curve of the afterglow on the screen of the scanning-tube. The output from the relay controls the efficiency of an amplifier X for the photo-electric currents, or the output is opposed to the photo-electric voltages on the grid of the valve N. As shown in Fig. 4, a second oscillograph K2 has an illuminating spot which is twice the width of that of the tube K and is one picture element in advance of a common element and illuminates a separate cell F2. A single oscillograph with a split beam may be used, and the light projected on the respective picture elements by mirrors. The difference between the two photo-electric currents is obtained by connecting external resistances W1, W2. Alternatively, the sensitivity of one cell or its amplifier is influenced by the currents from the other cell.

Title: An improved method of treating rayon
IPC: D06M13/02
Filed: 1930-02-03
Abstract: A protective coating for rayon fibres and threads which will lubricate during weaving or knitting comprises a mixture of a chemically inert mineral oil and a true mahogany sulphonate.  This latter is obtained from the sulphonated product of the fuming sulphuric acid treatment of lubricating stocks, which is known as the mahogany sulphonate of commerce and contains entrained oil, by separating the entrained oil with high proof alcohol.  The true mahogany sulphonate remaining mixed with an inert mineral oil produces a highly water-soluble combination.  Suitable mixtures contain 15-25 per cent of the true mahogany sulphonate and these can be readily removed from the rayon at any time prior to the dyeing by washing in water.  Suitable inert mineral oils are paraffin oil, or a light coloured technical oil with or without aromatic chlorinated solvents or low-viscosity mineral oil spirits.ALSO:Artificial silk yarns and fibres such as cellulose acetate, viscose, cuprammonia, and nitro-silks, are lubricated to form a protective coating during the weaving and knitting operations by the use of a mixture of a chemically inert mineral oil and a true mahogany sulphonate.  This latter is obtained from the sulphonated product of the fuming sulphuric acid treatment of lubricating stocks, which is known as the mahogany sulphonates of commerce and containing entrained oil, by separating the entrained oil with high-proof alcohol.  The true mahogany sulphonate remaining, mixed with an inert mineral oil, produces a highly water-soluble combination.  Suitable mixtures contain 15-25 per cent of the true mahogany sulphonate, and these can be readily removed from the rayon at any time prior to the dyeing and finishing operations without the customary severe scouring with fatty acid soaps or the like and the abrasion and chemical action on the rayon incidental thereto.  As suitable inert mineral oils paraffin oil or a light-coloured technical oil with or without aromatic chlorinated solvents or low-viscosity mineral oil spirits may be used.

Title: Improvements in or relating to fluid pressure mechanism more particularly for use inconnection with the brakes of motor road and other vehicles or other machines
IPC: B60T11/224
Filed: 1928-02-09
Abstract: 310,583. Boughton, E. B., Emmott, W., and Brock, D. T., (trading as Automotive Products Co.). Feb. 9, 1928. Fluid-pressure. - Hydraulic transmission apparatus particularly for applying vehicle brakes comprises three cylinders in which work respectively two driving pistons and a driven piston, the driving pistons being simultaneously moved at unequal speeds as by a hand-operated lever so as quickly to take up the lost motion while only the piston which is actuated at the higher mechanical advantage is effective for applying the final pressure. As shown, there is mounted in a side wall of the reservoir 11 a casting comprising three hydraulic cylinders 12, 13, 14 in which work respectively a driven piston 17 connected to the brakes or other device to be actuated, and driving pistons 15. 16. The cylinder 13 is preferably of larger diameter than the cylinder 12. A spring 30 is interposed between the piston 15 and a thrust member 31 which is engaged by the shorter arm 33 of a double-armed lever secured to a shaft 32 operated by a hand lever or equivalent, the longer arm 34 of the lever engaging the piston 16. Ports 36, 35' through the piston 16 are controlled by a non- return valve 37 and by an oppositely-acting spring-pressed valve 35. During the initial movement of the arm 33, 34 to apply the brake &c., by reason of the more rapid movement of the piston 16 and its greater diameter, liquid is rapidly forced thereby past the non-return valve 27 to act upon the piston 17 whereby the brake is rapidly moved to the engaged position. The consequent rise of pressure in the system causes the valve 27 to close and the valve 35 to open so that the liquid subsequently displaced by the piston 16 flows into the reservoir 11 and the final pressure is applied only by the piston 15 at a high mechanical advantage. During the final movement of the piston 15 it is engaged directly by the thrust member 31, the spring 30 being compressed. In the return movement, the non- return valve 37 opens to permit the return of liquid from the reservoir 11 to the cylinder 13, excess liquid in the cylinders 12, 14 being returned to the reservoir through the port 29, which is afterwards closed by the piston 15 so as normally to maintain a low pressure in the cylinders.

Title: Improvements in or relating to aiming devices on or for weapons for combatting mobile targets
Inventor: KUHLENKAMP ALFRED
Filed: 1954-02-12
Abstract: 787,574. Sighting devices. MATHEMA CORPORATION REG. TRUST. Feb. 12, 1954, No. 4142/54. Class 92 In an anti-aircraft gun, the aiming device comprises a drag roller 9, Fig. 5, movable over the surface of a rotatable sphere 7 and means 8, 4 moving the drag roller relative to the surface of the sphere in two planes disposed at 90 degrees to each other in proportion to the angle of sight y and to the bearing angle # respectively whereby the roller 9 is adjusted into the apparent angle of flight # by a turning movement in the plane containing its rotational axis 11 and about an axis perpendicular to the surface of the sphere 7. This turning movement or the drag roller is used in the sighting device to rotate an opaque disc 27, Figs. 5, 6 with transparent curves 28 indicating aiming-off values for selected target speeds and a superposed disc 29 with a radial slot 30 provides a luminous radial line, the intersection of this line and one of the curves selected for the estimated target speed being the point which is maintained on the target, the optical axis of the sight, which is parallel to the gun barrel, then being directed towards the strike point. A hemisphere 4, Fig. 5, is rotated through the angle of sight y by means of a shaft 5 and at the same time is rotated through the bearing angle # via the bevel gears 6. At the point of contact between the hemisphere 4 and the sphere 7 a drive speed of # # cos γ is obtained. A roller 8 is disposed at 90 degrees to the drive plane and drives the sphere 7 through the angle of sight y. The resultant velocity is recorded through the drag roller 9, whereby the rotation of the roller 9 on the axis 11 gives the angular velocity in the plane of flight and the turning of the roller 9 around the shaft 10 gives the apparent angle of flight #. This turning movement is conveyed by gearing to the discs 27, 29 connected by a shaft 35 on which a frame 37 is rotatably mounted, the disc 27 being mounted on the frame. A guide rim 34 is displaced by an eccentric disc 38 in the direction of a guide slot 39 by the valve cot # the rim 34 serving as a guide for a roller 33 rotating on a shaft 36 carried by the frame 37. Since the frame 37 with the shaft 35 is rotated proportional to the angle #, the frame 37 together with the disc 27 is rotated on the shaft 35 approximately proportional to cot γ cos # which is equal to cot # # where # # is the bearing angle in the plane of flight. The aiming-off curves 28 are indicated in relation to cot # # and the intersection of the luminous radial line provided by the slot 30 with a selected curve will indicate the point to be maintained on the target.
