Title: Improvements in or relating to time-division multiplex communications
IPC: H04J3/06
Filed: 1965-08-09
Abstract: 1,076,063. Multiplex pulse code signalling. SIEMENS A.G. Aug. 9, 1965 [Aug. 13, 1964], No. 33960/65. Heading H4L. In a time division multiplex digital communication system a synchronizing signal is transmitted by periodically replacing signal elements of specific channels by synchronizing signal elements which together form a digital code number, the synchronizing elements being transmitted in different channels in succeeding frames and arranged so that the time intervals between successive synchronizing signals are equal. An eight-channel system (K1 to K8), Fig. 1 (not shown), is described using a seven-element code, frames (R1 to R9) being indicated. The 7th digit time slot of frame (R1) is used for the first digit of the synchronizing signal (k), the 7th digit time slot of frame R2 is used for the second digit, and so on. The period of the sync. signal extends over nine frames but frame R9 contains no sync. code element to provide a time interval of sixty-three time slots before the first digit of the succeeding sync. signal appears. Receiver.-The incoming signal Si, Fig. 2, is fed to the demodulator 1 and also to a pulse generator 2 which extracts the basic repetition frequency Tg applied to control the demodulator 1. Pulses Tg are also supplied via an INHIBITOR gate 3 to a frequency divider 4 of ratio 7 : 1 to provide channel pulses Tz controlling the demodulator 1 and the channel distributer 5 which co-operates with the channel switches 51 to 58. Frequency divider 4 feeds a further frequency divider 7 of ratio 8 : 1 producing frame pulses Tg controlling the channel distributer 5 and a code number generator KG which produces the code number k. Divider 4 also feeds a frequency divider 6 of ratio 9 : 1 producing pulses To controlling code generator KG. The output of code generator KG is supplied via an EXCLUSIVE OR gate 8, to which the received signal Si also is applied, to an AND gate 9 receiving also the pulses To. Each ninth frame pulse Tp will coincide with an eighth sync. code pulse, i.e. with a pulse To and when applied to the code generator KG, the binary sequence 00000001 is generated and this sequence is compared in gate 8 with the incoming signal. If synchronism has been lost, a pulse is supplied by AND gate 9 which via delay 10 inhibits gate 3 and suppresses the next pulse in the train Tg, this process being repeated until synchronism is regained. The sync. code may be a pseudorandom sequence produced by a chain code generator, Figs. 4 and 6 (not shown). The sync. signal may be located in time slots normally allotted to control signals, Fig. 7 (not shown).

In the construction shown, used for the drying of starch, chamber 10 connected to an evacuator 11 is provided with hollow tables 13, 14 communicating with a steam supply pipe 37. The tables are connected to a shaft 19 which is adapted to be rotated by means of an electric motor 48. The shaft carries radial arms 53 provided with scrapers 17 which are adapted to move the starch over the tables. The starch is discharged over the outer edges of the tables 13 on to the tables 14 on which it is moved inwardly for discharge through central openings 20. It is finally received by a table 13 from which it is discharged through rotating valve 12a. This valve is of the same construction as a valve 12 through which the starch is fed into the chamber 10. Each of the tables is divided underneath into a number of passages by concentric ribs 28. The passages communicate with a common inlet passage 35 connected by a pipe 36 to the supply pipe 37. Water of condensation is discharged from the passages through separate ports 38 .. 41 communicating with steam traps 42. The arms 53 are connected by resilient strips 75 to frames carrying rollers 18 adapted to break up lumps of starch. Each roller comprises several twisted bars 69 rotatably mounted in end discs 62, which are rotatably mounted in a frame 70. The rotary valve for the supply of starch comprises a rotary member 89 provided with pockets 83 adapted to register with an inlet passage 84 and with an outlet passage 85. An air inlet valve 96 is normally opened and permits atmospheric air to blow starch from pocket 83 through the passage 85 into the evacuated chamber 10.

Title: Improvements in or relating to the production of acetals and dibasic acids therefrom
Inventor: BLACKMORE RICHARD LYE
IPC: C07C409/04
Filed: 1956-11-16
Abstract: Acetals are obtained from unsaturated fatty acids containing one or more =C-C-C= units by treating the fatty acids or their alkyl esters with a gas containing ozone, e.g. ozonised air, at a temperature between -50 and +130 DEG C. in the presence of an aliphatic primary alcohol having 1-4 carbon atoms and submitting the resulting solution to catalytic hydrogenation at a temperature between -10 and +60 DEG C., adding a little mineral acid to accelerate acetal formation and recovering the acetals from the alcoholic solution by distillation, after neutralising the free acid.  The acetals so obtained may be converted to dicarboxylic acids by submitting them to acid hydrolysis to convert them into aldehydes and then to oxidation to convert them into acids ; any esterified groups may be converted to carboxylic groups by hydrolysis.  In the examples : (a) a solution of methyl linoleate in methyl alcohol is treated with ozonised air, the product is catalytically hydrogenated, sulphuric acid is added and the product is neutralised with potassium carbonate; a mixture of malondialdehyde tetramethyl acetal, caproaldehyde dimethyl acetal and methyl azelate semi-aldehyde dimethyl acetal is obtained; and (b) a mixture of methyl esters of linseed oil fatty acids is treated by the process of (a) to give a mixture of malondialdehyde tetramethyl acetal, methyl azelate semialdehyde dimethyl acetal, pelargonaldehyde dimethyl acetal, caproaldehyde dimethyl acetal and propionaldehyde dimethyl acetal.  The methyl azelate semialdehyde dimethyl acetal prepared as in (a) or (b) is hydrolysed with sulphuric acid and then treated with ozonised air ; the resulting solution of the half esteris saponified with caustic soda, cooled and acidified to give azelaic acid.

Abstract: 1,100,744. Measuring temperature electrically; resistance measurement. BISSETTBERMAN CORPORATION. Aug. 17, 1965, No. 35271/65. Headings G1N and G1U. [Also in Divisions G3 and H3] A sensitive transducer (measuring e.g. temperature or pressure) is included in one bridge in the regenerative loop of a phase-shift oscillator (see Division H3) to provide a variable-amplitude constant-phase signal which is combined vectorially with the output of a second bridge which provides a constant-amplitude signal of constant phasedifference from the first signal; variations in the resistance of the transducer thus alter the frequency of oscillation. In Fig. 2 a thermistor or platinum thermometer 180 is in the first bridge 174, and may be used for measuring the temperature of sea water. A variable resistor 192 is adjusted so that the bridge 174 is balanced at one end of the range to be measured, e.g. 0‹C. The second bridge 194 has reactive components 212, 216 (one of which may be omitted) to provide a constant phase-shift, with a variable resistor 208 so that a definite frequency of oscillation occurs at a predetermined temperature. A further variable resistor 226 controls the frequency change per unit change of temperature; this also depends on the turns ratio of the transformer.
