Abstract: 1,217,303. Water-soluble tetracycline complexes. I. MARCUS. 12 June, 1967, No. 29967/69. Heading C2A. A novel water-soluble complex of a tetracycline and methyleneamino-salicylic acid or a salt thereof, is prepared by reacting in a solvent a tetracycline with the said acid or its salt. The complexes are said to be simple addition compounds; in the case of tetracycline itself the complex has the formula The preferred salt is that of sodium, and the reaction is suitably carried out in methanol, under an inert atmosphere (e.g. nitrogen) in the absence of light. The complex separates as a precipitate which is filtered off, washed with methanol and dried. The product is anhydrous and may be hydrated by allowing it to stand in moist air. The complex is unstable in aqueous solutions, but its stability is increased by increasing the concentration of the solution. The complexes react with streptomycin, neomycin or dihydrostreptomycin in solution (e.g. in ethanol) to liberate the tetracycline and form a corresponding addition compound with the reacting antibiotic. Pharmaceutical compositions having antibiotic activity comprise the tetracyclinemethyleneamino-salicylic acid complex or its physiologically acceptable salt together with a pharmaceutical carrier or diluent; the compositions may be in forms suitable for parenteral, oral or rectal administration.

Title: Facsimile transmission systems
IPC: H04N1/419
Filed: 1974-07-09
Abstract: 1455962 Data transmission; facsimile systems SIEMENS AG 9 July 1974 [13 July 1973] 30274/74 Heading H4P In a facsimile system where binary signals representative of black/white are run length coded into one or more words, a different signal is developed from a comparison of a present code word and the length of at least one preceding run of the same colour. It is preferable that the or the first, code word is derived from an estimated value L for the individual run length, L being the arithmetic mean weighted by a factor G of the length Lh of the previous run of the same colour in the same line and the length Lv of a neighbouring run of the same colour in the preceding line in accordance with the equation # = (1 - G) Lh+GLv where Lv is chosen so that it overlaps the first image point being coded or follows such point in the direction of scan. Good results may be obtained for G = 0À5, or G may equal 1 if there is strong correlation between lengths of individual runs. At regular intervals e.g. every 10 scan lines, G may be changed to O to provide a new reference, hence block continuance of errors. An image 1 is scanned linewise at 2 producing a synchronous bit sequence under control of pulse generator 6. Coder 3 forms signals into asynchronous blocks and via adder 4 and store 5 passes them to channel 10. Coder 3 at the end of each scan line interleaves a sync. and line start word, which may be a 31 bit pseudo random sequence. Coder 3 comprises a black/white change detector which enables a counter 14 which at the next change passes its content L to computer 22. Input is also passed to store 11 having a delay = 1 scan line which has an output to 12 corresponding to the shortest interval to a neighbouring run; directly after each black/white change, 12 detects whether this corresponds to the same colour or not. L is also applied to horizontal run length store 19 (Lh) and vertical run length store 18 (Lv) : stores 18, 19 may be commoned. Store 19 supplies run length Lh of colour last coded in the same line and 18 similarly in the preceding line, at that instant that comparator 12 produces a comparison result. Computer 20 then applies factor G to the comparison also supplies a number to computer 22 which codes L in words of n bits using a single or multiple word which is determined by 21. Counter 16 counts the number of points in a line and then increments 17 which supplies a line sync. pulse c. At k counts from 17, factor G is set to zero. A 31 bit pseudo random sequence from store 8 is supplemented by a bit indicating the first colour. It is also fed to 20 which determines a suitable code length n for the first run of each colour in each scan line which may be different for black/white. If the coding rate is higher than pulse rate 6, a multiplier 7 may be inserted; transmission rate may be controlled by a separate generator 9. Buffer store 5 balances input with transmission rate and is prevented from overflow or emptying by methods known in the art.

Title: Improvements in or relating to control of conditions, and treatment of materials, infurnaces
IPC: C21D11/00
Filed: 1952-08-08
Abstract: 742,853. Automatic temperature control systems. MUNKER, T., and SPADAS AKT.- GES. Aug. 8, 1952, No. 30351/50. Class 38 (4). [Also in Group XL (b)] In a method of heat treating materials passing through a continuous heating furnace the furnace is divided into two zones. In the first the material attains a temperature below the required treatment temperature and then passes through the second zone the temperature of part of which is maintained above the treatment temperature, the temperature of the material under treatment being detected just before the second zone and its speed of passage through the furnace regulated in accordance with the temperature so that the material is heated to the required treatment temperature during its passage through the second heating region. As shown, metal strip B to be annealed passes into a furnace G between rollers 2 and passes out at the other end through rollers 3 the furnace being downwardly inclined towards the centre so as to allow for sag of the strip. The furnace is divided into a number of sections A ... E each of which is provided with heating elements 1. Sections A and B constitute the first zone; sections C to E the second. The temperature of the heating elements or wall surfaces is maintained constant by means of pyrometers or thermo-elements 11 which supply automatic control systems 12 of known type. Situated above a passage 31 in the masonry of the furnace is radiation measuring device 33 which may be inclined to the path of travel of the material through the furnace by means of a hand wheel 39 and a worm and worm wheel 38. Also the angular function of the device about an axis perpendicular to strip travel may be adjusted through shafts 43 gears 48 and a hand wheel 50 which simultaneously adjusts a pointer 47 to indicate in which direction the device is pointing. Cell 33 measures the material temperature before it enters the second zone and controls the rate of feed through the second zone so as to ensure that the material reaches the correct final temperature. When continuous strip is not used a light source 91 and associated photo-cell 92 may be used to render the control system inoperative unless material is in the necessary position. A cam 23 driven in synchronism with the strip feed closes contacts one for each furnace length of material passing. Circuits.-Accordingly as the temperature of the material is too high or too low one of relays 63, 64 is closed, completing the circuit of one of coils 77, 79, through cam-operated switch 25 and normally closed contacts of time-lag relays 68, 75. Coils 77, 79 control the direction of rotation of servomotor 80 which in turn controls the gear ratio between the strip feed motor 10 and the strip. The time lag relays transfer the reversing coil circuits to normally open contacts and drive servomotor 80 for a period dependent on the fall-out time of the relay.
