Title: Microprogramme controlled processors
IPC: G06F9/24
Filed: 1976-03-19
Abstract: 1536224 Data processing SIEMENS AG 19 March 1976 [20 March 1975] 11046/76 Heading G4A A microprogrammed processor has a read/ write microprogramme store WCM with an access time greater than the processor cycle time, and a high speed buffer store MC and is arranged so that a plurality of microinstructions are loaded into the buffer from the microprogramme store, are marked "valid", are subsequently accessed when "valid" from the buffer to control the processor, and are then marked "invalid". The processor operates in two modes, viz. "normal" and "loop". In the normal mode the higher order bits of address register AR access microprogramme store WCM to access a plurality, e.g. two, microinstructions. The first microinstruction is loaded in instruction register MBR from where it is decoded DEC to control the system. The second microinstruction is loaded in the buffer MC addressed by the lower order bits of the address register and an associated marker bi-stable MCP is set "valid". The accessed marker bi-stable is then tested and, since it indicates "valid", the second microinstruction is accessed from the buffer MC to be decoded and the marker bi-stable is reset "invalid". When the next marker bi-stable is tested it indicates "invalid" and network FMB sets the address register in response to the second microinstruction to access the microprogramme store WCM for two further microinstructions. In the loop mode the microinstruction before the loop indicates loop operation and the system operates as above except that the marker bi-stables are not reset "invalid" when a microinstruction is accessed from the buffer so that, for example if the first microinstruction above indicates a loop the second and subsequent microinstructions will be stored in the buffer. The last microinstruction of the loop includes a test to determine whether the loop is to be repeated from the buffer store or whether the next microinstruction is to be accessed. The instruction following the loop resets the marker bits "invalid" so that the loop is not repeated. If the loop is a low level loop within a nest, processing proceeds as before and each instruction is stored in the buffer. When the processor exits from the highest level loop the next instruction acts to reset all the bi-stables "invalid" to cancel the loop.

Title: Improvements in or relating to the recovery of penicillin
Filed: 1946-04-12
Abstract: Penicillin is recovered from fermented broth by a process comprising the vigorous agitation of a solvent phase separated from the broth and containing the broth emulsified therein, which may have been separated from an emulsion of broth and solvent, preferably containing a de-emulsifying agent, whereby the emulsified broth is de-emulsified and the separation of the solvent layer from the de-emulsified broth.  The process can be applied to a solvent layer obtained by the counter-current extraction of crude penicillin-containing a minor proportion of aqueous phase emulsified therein.  Suitable solvents for the process include amyl acetate, butyl acetate and methyl cyclohexanone.  The extraction technique can also be extended to the use of basic aqueous solutions and suspensions.  Cetyl trimethyl ammonium bromide is suitable for use as a de-emulsifying agent.  In examples: (1) filtered fermented broth, butyl acetate and phosphoric acid are mixed and run into an agitator. Emulsified butyl acetate is run off and the remaining liquid agitated.  Spent broth may then be run off leaving clear butyl acetate in the agitator from which the penicillin may be extracted; (2) as in (1) using sulphuric instead of phosphoric acid and using cetyl trimethyl ammonium bromide as a de-emulsifying agent; (3) as in (2) using butyl acetate already used in six previous extractions and obtaining penicillin as its calcium salt.

Filed: 1975-03-19
Abstract: 1507063 Colour television PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 19 March 1975 [22 March 1974] 11418/75 Heading H4F Chroma keying signals are produced directly from modulated subcarrier signals of the PAL or NTSC type. In a first embodiment a further signal of subcarrier frequency, having an amplitude equal to, and being 180 degrees out of phase with, a sub-carrier representing the chroma keying saturation and hue, is added to the modulated subcarrier, and the keying signal is generated whenever the amplitude of the added signal falls below a threshold level. Increasing the threshold level increases both the ranges of saturation and hue in which keying occurs. In a second embodiment a reference subcarrier B of adjustable phase related to the keying hue is used to provide double carrier frequency pulses C (via a double phase rectifier) for gating the modulated carrier A. When the gated signals fall below a first adjustable threshold level determining the keying hue range, i.e. when signal A is of a phase falling within the selected hue range or is 180 degrees out of phase therewith, a signal D is produced. Carrier frequency pulses E, derived via a diode from signal B and displaced 90 degrees from pulses C, also gate signal A, the amplitude and polarity of the gated signal determining whether signal D is or is not transmitted to an output as the keying signal H, i.e. the polarity is used to resolve the 180 degree phase ambiguity, and the amplitude is compared with an adjustable threshold level determining the minimum saturation of the keying hue above which keying is desired to occur. Further pulses F, at 180 degrees to pulses E, may be used in similar manner to pulses E if the gated signal is first negated, the use of both signals E and F increasing the speed of response to changes in signal A. In a PAL system, the phase of signal B would undergo line by line alternation.
