Abstract: 1484328 Telegraphy; generation of set characters GDANSKIE ZAKLADY ELEKTRONICZNE UNIMOR 18 Dec 1974 [18 Dec 1973] 54797/74 Heading H4P An arrangement for generating set telegraphic characters, e.g. address, alarm, or distress signals comprises a pulse generator 1 producing two outputs in phase opposition stepping a distributing register 2 having the facility of blocking shift pulses. Each output from 2 causes a series of set characters to appear at the output of an encoder 3, e.g. SOS, and a further set of alterable characters, e.g. designation and position of a ship can be set up through a programming circuit 5. Parallel characters from 3 are converted into serial dot-dash signals of the international radio telegraphic code at 4. Each signal issued by 14 releases the register 2 causing issue of the next character. Switch on of the apparatus corresponds to the start of sending an alarm signal which consists of 12 dashes of 4 seconds each with a rest of one second, such signal being formed by appropriate frequency dividers in generator 1. During this time register 2 and coder 3 remain in their initial state. A subsequent impulse from generator 1 causes register 2 to be shifted to its next position thus causing coder 3 to issue the first of its set characters, register 2 being stepped through its stages as each character is transmitted.

The starting material may be prepared thus: 2,3-Dimethylphenol and malic acid are reacted with H 2 SO 4  to give 7,8-dimethylcoumarin, which is then reacted with Br 2  and the bromine derivative decomposed in ethanolic KOH to 6,7- dimethyl-benzofuran-2-carboxylic acid; the latter is then reduced to give the 2,3-dihydro-derivative which is reacted with AlCl 3  and valeryl chloride to give 2,3-dihydro-5-valeryl-6,7-dimethyl-benzofuran-2-carboxylic acid; the latter on reaction with formaldehyde and H-Am yields the starting material which is not isolated. Pharmaceutical compositions comprise the novel compound together with a suitable carrier and are administered orally as diuretics and saluretics.

A second inlet passage 72 normally communicates with exhaust 88 but on operation of the spool 44 check valve 184 opens to allow the fluid from inlet 72 to combine with that from inlet 76. Spools 42, 44 are mechanically coupled to move together. Work ports 172, 174 communicate with relief valves 176, 178 and anti cavitation valves 180, 182. Two further spools 38, 40 are provided each with their own relief and anti cavitation valves and inlet, exhaust and work passages. The two further spools have separate inlets 68 and 70 and the spool 40 is pilot pressure operated. Spool 40 will use both inlet 68, 70 if spool 38 is not operative and similarly spool 42 will use all three inlets if spools 38, 40 are not operative. Spool 40 which is to control track motors is provided with a pair of pressure regulating overspeed valves 136, 138. All the spools are centred by conventional end spring mechanisms (not shown).

[Also in Division C3] A polycondensate of caprolactam and 8- aminoctanoic or 11-aminoundecanoic acid comprises the recurring structural unit -A<SP>1</SP>-B n - where A<SP>1</SP> is the monomer unit derived from the acid and B that from the lactam and n is 2, 3, 4, 5 or 6. They are prepared by (a) reacting in substantially integral molar proportions from 2 to 6 moles of lactam per mole of acid in an inert atmosphere at above 145‹ C. to form an oligomer A-(B) n -OH, where A is the acyl radical of the acid and then (b) heating the oligomer under polycondensation conditions to form the polycondensate. " Substantially integral " is defined as differing from an integer by not more than 0À15 and the molar ratio for reaction is arrived at after correcting for unreacted lactam but may be allowed to remain and function as plasticizer. Step (a) may be effected at 170‹ to 200‹ C. and (b) with a steady increase to 260‹ C. In examples step (a) is effected in the presence of about 10 wt. per cent water in an autoclave or continuous polymerizer and except in Example IV about 0À34 wt. per cent adipic acid after about 3 hours reaction. In Example IV a 1 : 1 molar reaction product of caprolactam and adipic acid are used in place of adipic acid. Theory is adduced to support the postulation that the described procedure leads to the oligomer and polycondensate of the specified formula; the structure of the products of the examples is not otherwise established. The polycondensate may have a molecular weight of 30,000 to 50,000 and be usedfor oriented films or fibres or mouldings. Films and fibres of the polycondensates may have a residual elongation of 10 to 25% and be drawn to a permanently stretched length of 4 to 7 times the undrawn length. In a typical elongation two tandem 4-foot bars heated at 200‹ to 250‹ F. and 460‹ F. respectively each define a 3-inch opposed pair heating gap. A capstan adjacent the first bars delivers filament at 40 feet/min., another between the bars takes up and delivers at 190 feet/min. and a third adjacent the second bars takes up 10 mil. filament passing between the bars at 340 feet/min.
