Abstract: 1469751 Printers; data storage MULLARD Ltd 16 April 1974 [14 Feb 1973] 7303/73 Addition to 1469231 Headings G4H and G4C The invention is a memory (for a page printer) having addressing counters which can be connected in different arrangements by switches. In Fig. 2, 17 lines of 64 characters (each of 8 bits) per line, are received serially by line, character and bit, at I/P and stored in nine 1024-bit memory units Mc1-Mc9, two lines per unit (except unit Mc9, the second half of which is unused) under control of a chain of counters C1, C2, C3, C4, C5 of 3, 2, 4, 1, 4 bits respectively, the chain being driven by clock pulses CP, and switches S1, S2 being in the positions shown so each counter (except C5) drives the next in the chain. Counter C1 selects bits within a character, and counter C5, via a decoder D1, selects the memory units Mc1-Mc9, C4 and C5 in combination selecting the line. For read-out to a read only memory controlling a matrix page printer, the switches S1, S2 are reversed so that the first character of each line is read out, serially by character and bit, then the second character of each line, and so on. For this, pulses CP drive C1 which drives C4 which drives C5, to read out a given character in each line, this being done 42 times viz. 7 x 5 times for the matrix build-up of each character plus 7 Î 1 times for a space between characters. Then an end-of-character signal EOCHC drives C2 which drives C3, to select the next character position, which is read out for all the lines in turn, 42 times, as before, and so on. Each memory unit Mc1- Mc9 is a MOS memory on a semi-conductor chip, or uses magnetic cores.

Title: Improvements in the purification of resinous and wax-like products
IPC: C09F1/00
Filed: 1930-03-07
Abstract: Crude resinous and wax-like materials of vegetable or animal origin are decolorized by mixing them with at least 50 per cent by weight of absorptive carbon and treating the mixture with an organic solvent. Waxes such as beeswax, or shellac wax, or balsams, e.g. Peru balsams, alcoholic or ethereal extracts of vegetable materials, e.g. cannabis, or aloe, or wool fat or high molecular alcohols such as sterols are treated.  The raw material may be dissolved in a solvent, e.g. non-aromatic hydrocarbons such as benzine, or esters, the absorptive carbon added and the resulting mixture extracted with a solvent different from the dissolving solvent, e.g. alcohol or a mixture of alcohol and benzene, whereby the raw material is separated into its components.  100 parts of crude wool fat are dissolved in warm benzine, and 200 parts of active carbon are stirred in.  After cooling the resulting pasty mass is extracted with alcohol.  The alcoholic solution is separated and distilled to yield a residue of cholesterol.  The first residue of wool fat and carbon is extracted with benzine and the resulting solution distilled to yield a residue of fatty acids and esters.  Before decolorizing the raw material may be prerefined, e.g. by treatment with nitric or sulphuric acid.ALSO:Crude vegetable resins, such as the ethereal or alcoholic extract of cannabis or aloe, are decolorized by mixing them with at least 50 per cent by weight of absorptive carbon and treating the mixture with an organic solvent.

Title: Improvements in and relating to reflex circuit arrangements
IPC: H03F3/48
Filed: 1947-03-19
Abstract: 633,430. Valve amplifying circuits. RADIO CORPORATION PROPRIETARY, Ltd. March 19, 1947, No. 7529. Convention date, March 25, 1946. [Classes 40 (v) and 40 (vi)] A reflex circuit for amplifying a modulated signal and the modulation derived therefrom, and having negative feedback at the modulation frequency, comprises a volume control having only one movable member which simultaneously adjusts the magnitude of the reflexed signal and the negative feedback. This prevents the distortion products of the higher frequency signals interfering with the modulation frequency output at low volume settings. The Figure shows a reflex amplifier for a receiver in which the I.F. signal applied to the control grid is amplified in valve V1 and fed from the tuned anode transformer T2 to a diode detector D. Potentiometer R1 forms the diode load, and the slider feeds the detected signal to the control grid for further amplification. The resulting audio output is fed from the anode resistance R4 to a further amplifier circuit comprising a valve V2 and an output transformer T3 having a feedback winding connected in series with the diode load. Due to the series connection of this load and the detector impedance, the feedback increases as the volume is turned down. A resistance R7 connected between the upper terminal of, or a tapping on, the load (Figs. 2 and 3, not shown), increases the rate of change of feedback. The invention may also be applied to a straight receiver (Fig.. 4, not shown). Specification 615,987 is referred to.

Abstract: 614,433. Saccharifying cellulose. HERENG, A. March 11, 1946. No. 7571. [A Specification was laid open to inspection under Sect. 91 of the Acts, March 23, 1946] [Class 127] A continuous process for the saccharification of cellulosic material comprises impregnating the material by sprinkling it with an excess of aqueous acid solution, maintaining the material in turbulent condition while subjecting it to an initial treatment by the acid in a gaseous state and then to a final treatment by the acid in a cold, gaseous, anhydrous state so as to dry the material and recover the acid used. In a preferred process comminuted wood is fed from silo 1 into mixer 2 where it is sprayed with aqueous hydrochloric acid. It then passes down tower 3 which may be of the type described in Specification 606,465, in countercurrent to gaseous hydrochloric acid which leaves the tower via pipes 23 and then passes through calcium chloride solution in tank 16 to be dehydrated before passing back to the apparatus via pipe 4. The treated wood passes up conveyor 8 and descends a second tower 9 through which passes anhydrous hydrochloric acid which leaves by pipe 20 to the recovery plant. The dried hydrolised wood is washed in vessel 12 to remove all sugars which are concentrated in vessels 13, inverted in autoclaves 14 and neutralized to a syrup of 18 degrees brix in vat 15.
