Title: Method and apparatus for catalytic reactions
Inventor: CHRISTENSEN AXEL
IPC: B01J8/04
Filed: 1961-06-26
Abstract: A method of carrying out gas-vapour reactions in a catalytic reactor comprises passing the gas-vapour mixture through a plurality of catalyst beds to react the mixture in each of the beds, removing the partially reacted gas from the reactor after it passes through one of the beds, quenching the gas with liquid to provide additional vapour, and removing from the gas any residual liquid not vaporized before introducing the gas into contact with the next catalyst bed.  The method may be effected in apparatus which comprises a plurality of segregated catalyst beds, 2, 3, 4, within a single reactor 1, means to conduct the partially reacted gas stream external to the reactor between the catalyst beds, means to contact the gas stream with additional liquid external to the reactor, means to completely separate the gas stream <PICT:0922259/III/1> from any residual liquid resulting from the addition of liquid, and means to return the gas stream to the next catalyst bed.  As shown means to conduct the partially reacted gas stream external to the reactor comprises removal pipe 12 vessel 13 and input pipe 21. Within vessel 13 the partially reacted gases are contacted with additional liquid by a stream of water 16 dispersed by nozzle 17.  Residual liquid in the partially reacted gases is removed through valve 19.  Specified gas is air and specified vapour is methanol.ALSO:<PICT:0922259/IV(a)/1> Apparatus in which methanol air mixtures may be catalytically converted to formaldehyde comprises a plurality of segregated catalyst beds 2, 3, 4 within a single reactor 1, means to conduct the partially reacted gas stream with additional liquid external to the catalyst beds, means to contact the gas stream with additional liquid external to the reactor, means to completely separate the gas stream from any residual liquid resulting from the addition of liquid, and means to return the gas stream to the next catalyst bed.

Title: Improvements in television
IPC: H04N3/34
Filed: 1937-08-24
Abstract: 481,264. Television ; cathode - ray tubes. MICHAELIS, E. Aug. 24, 1937, No. 23177. Convention date, Aug. 28, 1936. Drawings to Specification. [Classes 39 (i) and 40 (iii)] The dimension of a scanning spot at rightangles to the scanning lines is equal to the distance between lines, the dimension in the direction of the lines is materially less, and the. cathode-ray producing the spot is less concentrated for dark than for bright spots. To obtain an elongated spot of light on the fluorescent screen, the plates, which deflect the ray along the lines, have an equal additional potential positive relatively to the anode, and the deflecting-plates, which effect the frame scanning, have an equal additional potential negative relatively to the anode. When deflecting-coils are used, they are given initial D. C. potentials, which compress the ray in the direction of the lines and expand it in the direction of frame scanning. Alternatively at least one diaphragm has an oval or rectangular aperture.

PCM channels on groups of incoming TDM highways 200, 201, are multiplexed at a higher rate on to corresponding rows of an intermediate highway switching matrix 214 the columns of which serve groups of outgoing highways 202, 203; the input to each row of the matrix having a phase adjusting device 212, 213, so that by selectively delaying incoming channels they can be aligned with any outgoing channels; distributers 210, 211, being provided for each column of the matrix so as to gate channels to the wanted highway of each outgoing highway group. Incoming and outgoing highways are shown grouped in fours and have 24 channels in each multiplex cycle, connections over the matrix being multiplexed at ten times the rate of the incoming and outgoing highways. Incoming PCM codes are set up in parallel in registers 204, 205, the four parallel codes presented at any one time by a group of incoming highways having ten possible matrix time slots in which they can be multiplexed on to an intermediate row highway. Choosing a matrix time slot that provides a free path to the channel and group of the wanted outlet, each received PCM code is directed to a phase-adjusting device 212, 213, with instructions for the code to emerge in that matrix time slot within the channel time slot preceding that of the channel of the wanted outlet. By coincident operation at this time of a matrix gate to the column of the wanted outgoing group and a gate in the associated distributer, the code is transferred to the register/transmitter 206, 207, of the wanted outgoing highway so that in the following time slot, which is that of the wanted channel, the code registered in parallel is transmitted in serial form. An expression is given for the blocking factor of the network in terms of the number of channels per highway, the number of highways per group, and the number of matrix channels per channel of the highways.
