Title: Improvements relating to apparatus for washing gas
IPC: B01D47/16
Filed: 1929-07-06
Abstract: 335,648. Brassert & Co., Ltd., H. A., (Brassert, H. A.). July 6, 1929. Scrubbers and washers.-In washers comprising alternate rows of oppositely-rotating or fixed and rotating bars &c. grouped round an axis and fixed nozzles spraying the bars in an outward direction, the bars are widest at their advancing faces, their radial dimensions diminishing symmetrically about a circumferential line passing through the middle of the advancing face and having a minimum clearance with the adjacent bars at that face. The rotating bars 16 of a washer comprising stationary and movable sections 11, 12 and spray nozzles 37 located in the radial path of the gas so as to wet circumferentially and axially the entire extent of the bars, are T-shaped in cross-section and so placed that the top of the T, i.e. its advancing face, is arranged radially of the central supporting disc 15. The bars are preferably formed from cylindrical bars so that the ends 38 of the T are rounded. The stationary bars 17 which are secured in place between the casing sections 11, 12 and bracing- rings 48 may comprise alternate long and short bars, the long bars passing through the casing and put under tension by nuts on the outside, the shorter bars being thereby compressed. A header 30 supplies the spray nozzles 37 through a valve 31 controlling each nozzle, any being removable on closure of the valve and disconnection of a coupling member. To dismantle the washer a bearing-member for the shaft 13 bolted to the stationary section 11 is disconnected and moved to the right with the rotor and shaft, the rotor having been temporarily suspended from a bracket 55 by a link 56 and a pin 57 passing through a hole in the disc 15.

Title: Improvements in or relating to Teleprinters
Inventor: BYATT DENNIS WILLIAM GEORGE
IPC: B41J2/41
Filed: 1967-05-04
Abstract: 1,156,885. Typewriters &c. MARCONI CO. Ltd. 22 Feb., 1968 [4 May, 1967], No. 20874/67. Heading B6F. In a teleprinter the characters are formed by selecting certain ones of a matrix of elements E1-E14, Fig. 1, each of which is connected to a separate wire to allow it to be charged, printing material being applied to the elements and electrostatically retained by the charged ones, to be transferred later to the paper. The elements are formed by photography and etching upon an insulating drum 1, Fig. 3. There are 64 lines each containing 64 matrices. The matrices of each line, e.g. 1M1-1M64 are selected in turn by a 64-stage ring counter inside the drum, stepped by clock pulses from a photocell 100 as it passes under a circumferential line of 64 electro-luminescent devices 1L0 &c. The first matrix 1M1 is selectively charged by a pattern of signals entered from a coding circuit through electro-luminescent devices 1L1- 1L14 and photo-cells 102-1014. In the next position of the drum the matrix 1M2 is selected and the elements are charged under the control of an adjacent row of electro-luminescent devices and photo-cells. At the same time the row 1L1-1L14 is charging the second matrix of the adjacent line 2M1-2M64. The matrices are selected by switching transistors rendered conducting by the corresponding outputs from the counters and selected elements in a selected matrix are charged via transistors controlled by the corresponding ones of photocells 1D1-1D14, 2D1-2D14 &c. The paper to be printed passes through an adhesive coating device on its way to the printing drum. The matrices pass over an ink powder container connected to the other pole of the charging current, so that charged elements pick up ink and transfer it to the coated paper which is pressed against the matrix by a pressure roller. After printing the paper passes through a drier and an earthing roller removes any remaining charge from the matrices.

Title: Improvements in or relating to Telecommunications Exchange Systems
IPC: H04L12/52
Filed: 1967-05-05
Abstract: 1,152,112. Telegraphy. SIEMENS A.G. 5 May, 1967 [6 May, 1966], No. 20956/67. Heading H4P. In a telegraph exchange system of the type in which the subscribers are connected by way of a common multichannel line, so that a subscriber may communicate with another by marking with each data pulse a combination of channels which is unique to the receiver, each transmitter TS is connected to a respective first gate unit EW. The first gate units are connected in a plurality of first groups, each group being in series with a respective second gate unit ZW. The second gate units are connected in series to gate unit HW by way of a calling line. If a transmitter TS in a first group of ten has data to transmit it enables gate AG and inhibits gate UG in the associated unit EW. It also enables AG and inhibits UG in the unit ZW, associated with the group of transmitters, by way of OR-gate ZMG which is connected to each transmitter in the group. The output of ZMG also passes to an OR-gate HMG, connected to each of the OR-gates ZMG. The output of HMG enables AG and inhibits UG in unit HW. When a call-up pulse arrives from AIG it therefore passes via gate AG of HW, through any enabled gates UG in the units ZW preceding that in which UG is inhibited, through AG in that unit ZW, through any enabled gates UG in the units EW preceding that in which UG is inhibited, and through AG in that unit EW to the transmitter TS. The transmitter can transmit only on reception of a calling pulse. If none of the transmitters associated with OR-gate HMG has data for transmission the call-up pulse passes via UG in unit HW to the unit HW associated with a similar arrangement to that described above.

Abstract: The invention comprises the indole derivatives of the formula <FORM:1061913/C2/1> in which R1 represents a hydrogen atom or a alkynyl radical, R2 methyl, C2- 4 alkenyl or C2- 4 represents a C2- 4 alkenyl or C2- 4 alkyny radical and R3 represents a hydrogen atom or a methyl radical, with the proviso that when R1 represents either a C2- 4 alkenyl or C2- 4 alkynl radical, R1 and R2 must be identical; acid-addition salts thereof; and their preparation by reacting an aminomethyl indole of the formula <FORM:1061913/C2/2> in which R represents a hydrogen atom or a methyl radical, with an appropriate alkenylating or alkynylating agent in an inert solvent and, if desired, treating the resulting compound with an organic or inorganic acid.  Aminomethylindoles of Formula II are prepared as follows: when R = H, by reducing a cyanoindole of the formula <FORM:1061913/C2/3> where R=CH3, by reacting a compound wherein R = H with a chlorocarbonic acid ester, e.g. the ethyl ester, to convert it to the corresponding urethane and subsequently reducing the urethane, e.g. with lithium aluminium hydride. 2-Methyl-6-cyanoindole is prepared by condensing 2 - nitro - 4 - bromobenzaldehyde with nitroethane in ethanol in the presence of potassium hydroxide to form the corresponding nitroalcohol from which 4-bromo-2,21-dinitro-21-methylstyrene is obtained by reaction with sodium acetate in acetic anhydride.  The dinitrostyrene is cyclized in ethanol/glacial acetic acid with iron powder to 2-methyl-6-bromoindole, which is heated with cuprous cyanide and the resulting 2-methyl-6-cyanoindole is reduced with lithium aluminium hydride.  Pharmaceutical compositions capable of inhibiting various pharmacodynamic effects of reserpine, having an inhibiting effect towards monoamine oxidase and having antihypertensive properties, comprise a compound of the invention, or an acid-addition salt thereof, and a pharmaceutical carrier.  The compositions may be administered enterally or parenterally in the form of tablets, dragees or injectable solutions.
