Abstract: 1497318 Polyhydric alcohols ICI UNITED STATES Inc 9 Dec 1975 [12 Dec 1974] 50485/75 Heading C2C A product containing a polyhydric alcohol is obtained by contacting a carbohydrate in an aqueous medium of pH 2-5 or above with hydrogen at a temperature between 100 and 200 C. and a pressure above 100 p.s.i.g. in the presence of a catalyst comprising ruthenium metal on a crystalline aluminosilicate clay having sheet or layer structure and base exchange capacity. The carbohydrate may be a monosaccharide or a polysaccharide; the monosaccharides are hydrogenated to polyalcohols containing the same number of carbon atoms; polysaccharides are hydrolysed/hydrogenated to give polyalcohols containing the same number of carbon atoms as their basic monosaccharide units. The clay is preferably one comprising a major portion of montmorillonite, e.g. bentonite or synthetic mica montmorillonite, and is preferably acid treated and calcined before deposition of ruthenium; the ruthenium may be deposited by ion exchange with an aqueous solution of a ruthenium salt, and may be reduced to the metallic state either before use or during the hydrogenation. When starting with polysaccharides the catalyst should be low in alkali metals, and the aqueous medium is preferably in the range 2À5-4À5. The product solution may be purified of electrolytes by treating with anion-exchange and cation-exchange resins before recovering the alcohol by conventional means. In the examples sorbitol is obtained with traces of mannitol from a cornstarch hydrolysate.

Title: Pulse frequency dividing circuit

Filed: 1972-11-07
Abstract: 1405918 Frequency dividers NIPPON GAKKI SEIZO KK 7 Nov 1972 [12 Nov 1971 (3)] A frequency divider comprises a first counter 1 which is reset after n or n + 1 input pulses, at T1, depending upon the state of a switching circuit 2; the reset pulses, at T2, are counted in a second counter 4 having in stable states; when the second counter is in one of x of its m states the switching circuit is in one condition but when it is in one of the other m-x states the circuit is in the other condition; the counter 4 completes a cycle and delivers a pulse at T3 every mn + x input pulses at T1. The reset pulses at T2 occur at m times the frequency at T3. In Fig. 1 both counters are shift registers SR1, SR2, the input frequency being applied to the clock input, and the registers having only one stage in 1 state. The output of the n<SP>th</SP> or (n + 1)<SP>th</SP> state of SR1 is fed back to the first stage dependent on the switching circuit 2 which includes two AND gates G1, G2 and an OR-gate OR1. The output of SR2 is fed back to form an m-scale ring counter; the outputs of x stages of SR2 are taken to an OR gate OR2 whose output enables one or other of the AND gates G1, G2. In alternative embodiments (Figs. 3, 4, not shown) the ring counter 4 is replaced by cascaded flip-flops and a decoder which selects the x states. The divider may be extended by repeating units 2, 3, 4 (Fig. 5, not shown). The divider finds particular application in an electronic musical instrument (Fig. 6, not shown) where all 12 notes of the top octave are derived from a single high frequency oscillator by dividing by different fractional values.
