Abstract: Vitamin B12 derivatives (cobamides) having attached to the cobalt atom a group R which is a substituted or unsubstituted aliphatic hydrocarbon group, an acyl group or an alkyl-, aralkyl- or aryl-sulphonyl group, are obtained by condensing fully-reduced Vitamin B12 or other cobamide with a compound of formula RX where R is as above and X is an anion-forming substituent e.g. a halogen atom or sulphate, phosphate, sulphonate or oxalate radical. With the exception of Vitamin B12 coenzyme and the Co-51-deoxy-adenosyl derivatives of other cobamides having the same side chains attached to the pyrrole rings as are present in Vitamin B12 itself, the compounds prepared by the process are novel.  In examples isopropylidine B12 coenzyme is prepared from reduced hydroxocobalamin and the p-toluene sulphony ester of isopropylidine adenosine, and converted to B12 coenzyme; B12 coenzyme is prepared from p-toluene sulphonyl adenosine and reduced hydroxocobalamin; the isopropylidine uridine analogue, uridine analogue, uridine coenzyme analogue, isopropylidine inosine analogue, inosine analogue, ethyl analogue, hydroxyethyl analogue, methyl analogue, acetyl analogue, benzyl analogue, carboxymethyl analogue, p-toluene sulphonyl analogue, bromo-uridine analogue, methane sulphonyl analogue, methyl and uridine analogues of B12 monocarboxylic acid, cobinamide, methyl cobinamide and deoxyadenosine analogue, are also prepared and some of these compounds are converted to the coenzyme forms.

Title: Apparatus for investigating high speed repetitive phenomena
IPC: H05B41/34
Filed: 1967-10-04
Abstract: 1,130,686. Photo-electric stroboscopes. INTERNATIONAL BUSINESS MACHINES CORP. Oct. 4, 1967 [Jan. 13, 1967], No. 45180/67. Heading G1A. [Also in Division H1] A repetitive phenomenon 8 is investigated by illuminating it with light pulses from a mode locked laser 1, 2, 2', 3, having a pulse repetition rate which is the same as, or a multiple or submultiple of the repetition rate of the phenomenon, and shifting the phase of the laser pulses relative to the phase of the phenomenon by an increment after a predetermined number of laser pulses. By detecting the light pulses after interaction with the phenomenon it is possible to obtain a representation of the phenomenon on an extended time scale. It is stated that the apparatus operates on a similar principle to a conventional electronic sampling oscilloscope. The laser includes a voltage controlled optical loss modulator 3 to which a modulating voltage is applied by oscillator 4, at a frequency corresponding to the axial mode separation of the laser. The pulse frequency of the laser is adjusted so that it is the same as (or a multiple or submultiple of) the repetition frequency of the phenomenon by adjusting the separation of laser mirrors 2, 2' and the oscillator frequency, and the pulse phase is set at a suitable position relative to that of the phenomenon. The detected pulses are passed through a low pass filter 10 to a sampling capacitor 11, the amplified voltage across which is supplied to oscilloscope 13. The pulses are also shaped and counted at 15, 16, and when a predetermined number has been received a staircase advance pulse increases the output voltage from staircase generator 17 by one increment. This voltage is used to deflect the display on the screen of oscilloscope 13 along the axis by an amount proportional to the time interval At between the corresponding laser pulse and a reference time within each interval between pulses. The staircase voltage also controls the phase of the voltage applied to loss modulator 3 to change the time interval At. The system operates in the same way without modification when the laser pulse frequency is a submultiple of the phenomenon repetition frequency, but when it is a multiple a shutter may be provided between the laser and the phenomenon or an electronic gate may disable photo-detector 9 or prevent charging of capacitor 11 during laser pulses between those required. The optical shutter may be a Kerr cell between crossed polarizers. A shutter or electronic gate may also be used to prevent a display during the first few laser pulses following a change in the staircase generator voltage, to allow equilibrium to be reached.
