Title: Interference suppression system
IPC: G06F3/00
Filed: 1991-03-15
Abstract: A line driver (12) is coupled by a pair of signal lines (10,11) to a receiver (13). Preprocessing circuitry (18), for processing signals arriving on the pair of signal lines at the receiver, includes regulating means (Fig. 2) for regulating the potential between the signal lines between predetermined limits and thereby modifying the sensitivity of the system to compensate for changes in line conditions and reject interference when the line driver is powered down. The regulating means comprise: bias means (Q1-Q3,Q12) for putting a bias on the signal passing through to the receiver, so as to hold the receiver input away from the triggering voltage level so that it is not triggered by noise; and bias limiting means (Q6-Q7,Q9-Q11) responsive to signals from the driver so as to limit or reduce the effective bias, so that the sensitivity of the system to true signals from the driver is not reduced below a desired level.

Patent ES-220866-A1 (ES)
Title: Process for separating tetracycline and chlortetracycline
IPC: C07C233/00
Filed: 1955-03-24
Abstract: Tetracycline is separated from chlortetracycline in aqueous solutions containing the same by adjusting the said solution to a pH of 0.5 to 3.5, extracting the two antibiotics into a water-immiscible organic solvent, separating the resulting extract, treating the said extract with water while adjusting the pH of the aqueous phase to pH 5 to 8 and crystallizing the tetracycline from the result mixture. This may be brought about by (a) allowing the mixture to stand 8 to 12 hours, or (b) removing part or whole of the solvent in vacuo. It is preferred to add a water-soluble inorganic salt such as sodium chloride, sodium sulphate, potassium sulphate, potassium chloride, ammonium chloride and ammonium sulphate to the antibiotic solution prior to the extraction with the organic solvent. Other additions are (a) sodium or potassium ferrocyanide to remove colour-forming substances and (b) ammonium oxalate to prevent precipitation of calcium salts. The mother liquor remaining after the removal of the tetracycline may be further treated to obtain a further crop of tetracycline crystals. Chlortetracycline is then recovered from the aqueous residue by known methods. The initial acidification is by means of inorganic acids such as hydrochloric, sulphuric and phosphoric. The aqueous solution of antibiotics may be a solution of the free bases, salts or complexes or a filtered fermentation broth. Specified water-immiscible organic solvents are alcohols such as butanol, isobutanol, pentanols and hexanols. Specification 690,381 is referred to.

Title: Process and three-component catalyst for propylene polymerization containing an organo aluminum compound and titanium tetrachloride-hydrogen sulfide or hydrogen selenide reaction product
IPC: C08F110/00
Filed: 1961-09-18
Abstract: Propylene is polymerized using a catalyst obtained by reacting an organometallic derivative of a Group I, II, III or IV metal with the hydrocarbon-insoluble portion of a complex compound obtained by the reaction of a transition metal compound with a compound H2X where X is selenium or sulphur. The hydrocarbon-insoluble portion of the complex compound is produced by reacting hydrogen selenide or sulphide with the transition metal compound, if desired in the presence of an inert hydrocarbon, washing the product in the absence of atmospheric humidity with a dry solvent and drying it under a vacuum. The preferred transition metal compound is titanium tetrachloride and the preferred organometallic compounds are alkylated, possibly halogenated, aluminium derivatives such as triethyl aluminium. The polymerization may be in bulk or in a solvent. In one of the examples the polypropylene obtained using a hexane solvent is filtered from the solvent, washed with dry hexane, treated with an alkaline solution of hydrogen peroxide, subjected to treatment with water vapour in the presence of NaOH and the purified polymer extracted wth boiling heptane.

Patent ES-336901-A1 (ES)
Title: Improvements in or relating to toy shooting ranges
IPC: A63F9/02
Filed: 1967-02-16
Abstract: A toy shooting range comprises a gun 3 having a trigger 24, a target 8 towards which the gun is directed, a striker pin 13 located behind the target 8, and a transmission interconnecting the trigger and the striker pin such that actuation of the trigger causes the striker pin to strike the target. In the construction shown the gun 3 is mounted on an upright arm 2 of an angle member 1, the horizontal arm of which comprises two parts 6, 7. The angle member 1 is suspended in gimbals 4 at the connection between the two parts. The part 7 carries pivotally at its end a lever 21 to which is attached an impact plate 20. The striker pin 13 is slidably guided under spring loading in a sleeve 14 secured to a carrier plate 16, the carrier plate being mounted on the part 7 for movement therewith. Movement of the sleeve and carrier plate assembly is limited by a frame 17 secured to a plate 18. The transmission includes a spring-loaded push rod 27 which co-operates with a latch 28 which in turn, in its cocked position, co-operates with a notch 30 in a spring-loaded actuating rod 29. The transmission is cocked manually by pulling a grip 40 rearwardly. On actuating the trigger the push rod 27 causes the latch 28 to rotate clockwise and disengage from the notch 30 to allow the actuating rod 29 to snap forward against the lever 21. The lever 21 and impact plate 20 then actuate the striker pin 13. In a further embodiment (Figs. 5, 6, not shown) the striker pin is attached to a spring loaded, pivotally mounted impact plate, the impact plate being actuated by a push rod. The transmission comprises a coupling link which co-operates with a face of the trigger at one end and is pivotally connected by a hook and eye connection to a spring loaded lever at the other. On actuation of the trigger the coupling link, lever and push rod are moved such that, at first, the pushrod moves away from the impact plate. On further movement an abutment face of the trigger engages the coupling link to disengage it from the trigger thus allowing the spring loading on the lever to urge the push rod against the impact plate thus causing perforation of the target.
