Abstract: 363,307. Artificial lines. WESTERN UNION TELEGRAPH CO., 195, Broadway, New York, U.S.A. Aug. 15, 1930, No. 24544. Convention date, Sept. 4, 1929. [Class 40 (iii).] Relates to artificial lines for use in high-speed telegraphy for balancing both the surge impedance and the propagation constant of a loaded or unloaded cable throughout a suitable frequency range. For balancing inductance and reactance, each section of the artificial line comprises two inductances 10, 13, and two resistances 11, 14, and these may be arranged as shown or in several other ways, Figs. 2 .. 6 (not shown). For balancing leakance and capacity, each section comprises one or more resistance-capacity arms 16 in shunt with large condensers 15, the time-constants of the arms 16 being different from one another, while the capacity 15 is distributed throughout the line to a greater extent than the arms 16. It may be shunted by simple resistance also if desired. The Specification shows how the leakance/frequency and capacity/frequency characteristics of the cable can be simulated by adding together the characteristics of the branches 15, 16. The invention is shown as applied to a loaded cable 2 with a non-loaded shore portion 1, these being separately balanced at 4 and 3 as described in Specification 246,429, [Class 40 (iii), Telegraphs, Electric]. Reflections due to discontinuities in the characteristics, of the cable are balanced by means of similar discontinuities introduced into the artificial line.

Title: Process and apparatus for automatically focussing an optical system
IPC: G02B7/28
Filed: 1976-06-15
Abstract: 1517648 Automatic focusing ERNST LEITZ WETZLAR GmbH 15 June 1976 [26 June 1975 (2)] 24719/76 Heading H4D In an automatic focusing system, e.g. for a microscope or a photographic camera, a grating 20 is movable in an image plane 19 by a distance exceeding a multiple of the grating constant, photo-electric receivers 23, 24, generating electric signals which are modulated in response to the movement of the grating 20 relative to the image for adjusting the focus of the image in plane 19. As shown, the signals are applied via a setting member 25 and amplifier 26 to a drive motor 27, which displaces the lens 13 or the table for automatic focusing in the direction of double arrow 28. The large movement of grating 20 compared with that in known systems compensates for variations in signal strength over the image plane. A blanking of the signals at the end points of the grating's movements prevents interference effects at the edge regions. The grating is periodic or aperiodic, in which case different spatial frequencies of the image can be evaluated. Amplitude or slit gratings or prismatic arrays may be used. A further embodiment utilizes a rotating disc on which several grating elements are arranged, Fig. 10 (not shown), and another embodiment uses an oscillating scanning disc with two rows of slits with different grating constants, Fig. 11 (not shown). A further arrangement, Fig. 9 (not shown), ascertains the phase difference from the signals obtained from two receivers allocated to diametral spaced pupil parts and the sign and magnitude of this difference are utilized to determine the direction and magnitude of defocusing. A light balance arrangement indicates to the user in which direction he needs to adjust the lens of the apparatus.

Filed: 1959-07-21
Abstract: 920,439. Hydraulic couplings. AMERICAN RADIATOR & STANDARD SANITARY CORPORATION. July 21, 1959, No. 25002/59 Class 69 (2). An hydraulic coupling comprises impeller and turbine members 27, 29, Fig. 1, providing a power-transmitting fluid circuit, and a damper plate 23 movable into and out of the space between the members to vary the flow of fluid in the circuit. The impeller and turbine members are mounted on driving and driven shafts 28, 30, respectively, and are disposed in housing parts 11, 12 bolted together and to plates 15, 16, 17, Fig. 3. The plates 15, 17 are provided with apertures 18, 19 of a diameter substantially equal to the internal diameter of the housing parts. The plate 16 has a slot 21 in which slides the damper plate 23. The damper plate may be moved from an upper position, in which the flow of liquid in the circuit is unrestricted, to a lower position in which flow between the members is prevented and the driven shaft is stationary, the movement of the plate being effected by a piston-andcylinder device 40 operated by mechanism responsive to the operating conditions. The liquid is supplied to the coupling by a pump and may be cooled by an external cooler or the damping plate may be hollow and formed with inlet and outlet orifices 100 and 101, Fig. 4, and baffles 102 . . . 108 to cause fluid supplied to the plate to flow in a sinuous path and extract heat from the fluid in the coupling. In another embodiment, the flow of fluid between the impeller and turbine is varied by three plates 50, 51, 52, Fig. 6, which are shaped so that when they are in their radially innermost position, the flow of fluid between the members is completely stopped. In a further embodiment, a pair of pivoted damper plates are provided which, when in their innermost position, do not completely stop the flow of fluid between the members.

Title: Improvements in or relating to synchronising systems
IPC: H04N5/04
Filed: 1930-08-21
Abstract: 350,813. Synchronous movements. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London.-(Assignees of Ranger, R. H. ; 574, Parker Street, Newark, New Jersey, U.S.A.) Aug. 21, 1930, No. 25036. Convention date, Sept. 21, 1929. [Class 40 (iii).] A copying-telegraph transmitter is driven at a predetermined speed, and synchronizing impulses are transmitted at times determined by the movement of the transmitter; a receiver is driven approximately synchronously with the transmitter and generates impulses at times determined by the movement of the receiver, and a correction is applied to the receiver dependent on the time relationship between received synchronizing impulses and the locally generated impulses. Transmitter, Fig. 1. At the end of each movement of the transmitter carriage, a contact arm 1 is moved from its rest position S to cut off the picture signals and enable current from a source 17 to move a relay 15 to the position M and transmit a marking impulse over a line 21 to a transmitter. When the arm 3 reaches its contact M, current from a negative source 25 moves the relay to its spacing position S. As the carriage returns the arm 3 leaves its contact M to cause the transmission of a second marking impulse, and returns to its contact S, when normal signalling is resumed. Receiver, Fig. 3. At the end of each movement of the receiver carriage, a contact arm 49 is moved from its contact S where it has permitted the charging of a condenser 61 from a source 55. The condenser discharges according to a logarithmic curve through a resistance 63 to ground 67. At the same time the synchronizing signals move a relay 45 to contact m, so that a charge, depending in amplitude on the relative movement of the arms 53, 45 is impressed by a conductor 69 on the grid 71 of a valve 73 across a condenser 81. Thus a current, depending on the lack of synchronism, passes through a relay 77 to a corrector coil 85 to speed up appropriately a fork 47, which runs slightly lower than the fork at the transmitter.
