Abstract: 1278498 Ticket printing LICENTIA PATENT-VERWALTUNGS GmbH 18 Aug 1969 [16 Aug 1968] 41117/69 Heading G4T A ticket printing machine comprises a fare printing device and a rotatable drum magazine for storing printing plates, one for each passenger destination, each plate being characterized by one output of a position switch P-Sch (Fig. 1) and a series of switches G-Sch in keyboard form identify type (e.g. single, second class) of ticket. The switch outputs are fed to a number of "AND" gates arranged in matrix form so that the output of each gate characterizes a ticket of one type and destination, and a signal from an "AND" gate is fed through fare plug boards Pst-Pl and Pr-Pl, which determine the fare to a coder Cod that activates type wheels of the fare printer. In a preferred from for railway tickets, the drum magazine is in the form of a rotary switch P-Sch, and comprises a rotor 1 (Fig. 3) having radial printing plate storage pockets 3 and a brush 4. The rotor 1 surrounds a stator 2 that supports laminations 5 and contacts 7 corresponding to the pockets 3. A signal is fed from a slip ring input 6 by the brush 4, to the lamination 5 and contact 7 corresponding to the selected printing plate. In an alternative form, the stator 2 is located to one side of the rotor 7 and brushed by a rotor arm. Each printing plate stores destination, departure station and distance. The maximum number of "AND" gates required is equal to the product of number of destinations, and number of ticket types. Each fare-stage plug board Pst-Pl (Fig. 1) receives the outputs from those "AND" gates corresponding to a common ticket type; each input is interchangeably connected to the output that represents the appropriate fare stage on a railway fare table. Interchangeably connected to each element Pst-Pl is a fare plug board Pr-Pl (such as a printed circuit), the outputs representing the fare chargeable to each fare stage. All outputs from the fare elements Pr- Pl are connected in parallel to the coder Cod. Signals SSt. and PSt. may be fed to a control centre for statistical analysis. Extra "AND" elements may be provided for activation by hand or by the control centre through a matrix of switches for destinations not represented on a printing plate. A separate type-wheel may be provided for printing distance and code numbers on to the ticket.

Title: Process for the manufacture of carbonyl compounds
IPC: C07C45/34
Filed: 1959-12-21
Abstract: Carbonyl compounds, namely aldehydes and ketones with some carboxylic acid, are obtained by reacting an olefine with molecular oxygen in the presence of a neutral to acid aqueous liquid catalyst containing a salt of a metal which can exhibit different valencies under the reaction conditions and is capable of being reduced to a salt of lower valency, so that the olefine and part of the oxygen are contacted with the catalyst in a reaction zone and some of the oxygen is contacted with the catalyst in a catalyst regeneration zone, the quantity of the liquid catalyst being passed in unit time to the reaction zone being greater or smaller than that passed in unit time through the regeneration zone.  Preferably a subsidiary stream of liquid catalyst is withdrawn from the main liquid catalyst after leaving the reaction zone or regeneration zone and is returned to the reaction zone or regeneration zone respectively.  If desired more than one subsidiary stream may be withdrawn from different parts of the catalyst stream.  The preferred catalysts are those containing a copper salt and advantageous a salt of a noble metal, particularly palladium.  In addition a salt of iron, chromium, manganese or cerium may also be present.  Suitable anions are, for example, chlorine, bromine, chlorate, perchlorate or nitrate ions or a mixture of one or more of these with sulphate or acetate ions.  Additional chlorine ions in the form of hydrogen chloride, acetyl chloride, ethyl chloride, tertiary butyl chloride or bromine trichloride are advantageously added. The pH value is preferably within the range 0.8-5.0 and the preferred temperature range is 50-160 DEG C. in both the reaction and catalyst regeneration zones which are not necessarily at the same temperature.  The process may be used, for example, for converting ethylene to acetaldehyde and acetic acid, propylene to acetone and propionaldehyde, butylenes to methylethyl ketone, butyraldehyde or isobutyraldehyde and butadiene to diacetyl and crotonaldehyde.
