The starting material, phyton, may be made according to the reaction scheme shown in Fig. 2.  Citral (II) is condensed with an acetal of b -ketobutyraldehyd where R is a C1- 6 alkyl group, to give the C14-pseudo acetal VI which reacted with a Grignard reagent CH3MgX (X is halogen) and the resultant organometallic compound hydrolysed to the C15-pseudo-hydroxy acetal (VII) which on acid hydrolysis in acetone yields the C15-pseudo-aldehyde (VIII).  This aldehyde is condensed with acetone to give the C18-pseudo-ketone (IX) which on catalytic hydrogenation yields phyton.  The C14-pseudo-acetal (VI) may also be prepared by formylating pseudo-ionone (III) by Claisen's method to give the enolate V which is acetalized with an alcohol ROH to yield (VI).  In the example some of the intermediates are characterized as the semicarbazones.

Abstract: 321,585. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Dec. 15, 1928. Pyrazolanthrone dyes.-New vat dyes are obtained by treating pyrazolanthrones with free 2- positions with 1-amino-2-halogenanthraquinones or their substitution-products or pyrazolanthrones which are halogenated in the 2-position with 1- aminoanthraquinones with free 2-positions in the presence of alkaline condensing agents, preferably in an organic diluting medium, and in presence of catalysts such as copper, its salts, oxides or mixtures thereof. They are of the following probable, structure :- Halogen derivatives are obtained by the action of a halogenating agent on the condensation products, preferably in an organic or inorganic dissolving medium, such as nitrobenzene, sulphuric acid, oleum, chlorsulphonic acid and the like. The halogenation generally produces an improvement in the clearness of the shade, and in the fastness to chlorine, and also a change in shade. In examples :-(1) pyrazolanthrone is condensed with 1-amino-2-bromanthraquinone; the product dyes cotton blue-violet shades; (2) pyrazolanthrone is condensed with 1 - amino - 2 - brom - 4 - hydroxyanthraquinone, to give a product dyeing bluegreen changing to grey by chlorination; (3) 2- brompyrazolanthrone is condensed with 1-aminoanthraquinone to give a dyestuff similar to that of example (1); (4) 2-brompyrazolanthrone is condensed with 1-amino-4-hydroxyanthraquinone to give a dyestuff similar to that of example (2) ; (5) 2-brompyrazolanthrone is condensed with 1 : 4- diaminoanthraquinone to give a product dyeing greenish-grey, fast to washing, and changing to Bordeaux red by treatment with chlorine; by employing 1-amino-5-benzoylaminoanthraquinone instead of the above 1: 4- -diamino-cornpound, a product dyeing greenish-grey shades is obtained; (6) the dyestuff from example (1) on bromination gives a product dyeing cotton violet shades, changing in air to a blue of good fastness to chlorine; (7) on chlorination of the dyestuff of example (1), a product is obtained dyeing cotton reddish-blue of good fastness to chlorine; (8) bromination of the dyestuff of example (4) gives a product dyeing similarly to the initial dyestuff, but having a purer tone and better fastness to washing.

Title: Searching for a desired microfilm image from a series of microfilm images
IPC: G03B21/11
Filed: 1971-08-06
Abstract: 1360829 Searching microfilm AGFAGEVAERT AG 6 Aug 1971 [6 Aug 1970] 37165/71 Headings G4H and G4M Apparatus for searching for a desired microfilm image (e.g. for reading or re-enlarging) from a series of images is disclosed. A microfilm strip 1 (Fig. 1, not shown) carries a seizes of microfilm images each having a clock pulse and a code mark representing a number in the Tompkins code (Fig. 2, not shown), the numbers along the tape being consecutive. The strip is driven through rollers 8, 9 by motor 4 and an electro-optical scanner (not shown) scans the code marks in sequence and passes them to shift register 15 which holds the current mark and shift register 16 which holds the immediately preceding mark. The code mark being sought is entered in shift register 11 via denary keyboard 10 and this is compared with the code mark in register 15 in coincidence circuit 12. The contents of registers 15 and 16 are compared in circuit 17 to determine if the two marks are consecutive on the strip. If both these conditions are fulfilled, AND gate 20a is enabled and switch 22 cuts off the current to the motor 4 hence stopping the strip at the desired image. The contents of register 15 are also compared with the contents of register 11 in unit 25 to see which is greater. If the value in register 11 is less (i.e. the film has moved past the desired value) then AND gate 20b is enabled and switches 28, 29 reverse the motor and hence the direction of the film. In one embodiment (Fig. 3, not shown) the number of reversals is counted in counter 33 and, after a predetermined number, the film is stopped, and a signal device 36 is activated. In Fig. 4 the counter, after a predetermined number, switches circuit 38 which calculates the difference between the number in registers 11 and 15. The difference sets counter 39 which, by means of an electro-optical scanner 40, counts the numbers of clock pulses passing. When the counter reaches the set value the film is stopped. A counter 42 counts the difference between the forward and reverse count, and passes it to register 43 where it is compared with the input 14 to register 15. If they do not agree, circuit 45 causes the operator to check. It is stated that if a desired code mark is erroneous because of dust &c., the continuous reversing about it may sweep the dust off. Continuous reversing about a region on the film also enables the operator to effect a manual search for the desired image if the code mark is erroneous.
