Title: Detection system for analog pulses
IPC: H03K5/153
Filed: 1968-02-26
Abstract: A pulse thresholding circuit (more particularly for use in document scanning apparatus) operating on the leading or trailing edge of pulses having uniform edge widths such as are produced by scanning systems of finite aperture comprises a comparator to the inputs of which are applied the signal pulse and a delayed signal pulse, one input path including an attenuator and the delay being such that an attenuated leading edge terminates or a trailing edge starts during the corresponding edge of the unattenuated pulse. In Fig. 5 the comparator comprises transistors 40 to 43 having a common emittercurrent source 45. The inputs to the comparator comprise respectively a variable threshold voltage 28, an attenuated pulse I (Fig. 4), a pulse II with one unit delay and an attenuated pulse III with two units delay. Initially the emitter current flows to transistor 40. When the attenuated pulse I exceeds the threshold level the current diverts to transistor 41 but when the delayed pulse II exceeds this the current diverts to transistor 42 and thus to output inverter 52. It remains in this path until delayed pulse II at 42 decreases below the double delayed and attenuated pulse III at 43 whereupon the current is diverted from the output circuit to transistor 43. The rectangular pulses shown in the lower line of Fig. 4 are thus obtained. With 50% attenuation and 50% of the rise time as a delay unit the comparator changes over at the 50% amplitude points but other points can be obtained with other values and for non-linear edge slopes. The threshold input prevents operation by small amplitude pulses and a diode 33 limits the input pulse excursions. In Fig. 6 (not shown), the second delay and attenuator is omitted and the transistor (57) corresponding to 43 stores in an emitter capacitor (59) the peak amplitude of the attenuated signal applied to transistor 40 and this capacitor is coupled by a diode (58) to the common emitter circuit so that the output pulse terminates when the delayed input pulse falls below this level. In Fig. 7 current normally flows through diode 65, resistor 63 and transistor 62. A positive-going input pulse causes 61 to conduct and the voltage across a capacitor 66 follows the input pulse. This continues until the delayed pulse becomes of equal value whereupon the bases become of equal voltage and conduction in both transistors ceases. Capacitor 66 stores the attenuated peak value of the pulse and capacitor transistor 62 conducts again only when the delayed pulse falls below this value.

Title: Improvements in or relating to Wired Broadcasting Systems
IPC: H04N11/16
Filed: 1968-05-16
Abstract: A wired broadcasting system comprises a transmitting apparatus 1 which receives PAL type colour television signals radiated from a broadcasting transmitter and modifies them for transmission on conductive network 2, 3 to receivers 6 and 7. In the transmitter 1 the received signals are fed to device 16 which provides on line 17 brightness information and suppressed carrier wave colour carrier information in respect of first and second colour carrier information signals, the phase of the second colour carrier information signal being periodically reversed, on line 18 line scanning pulses, and on line 19 colour bursts. The bursts are fed to a comparator 20 and frequency control arrangement 24 to synchronize an oscillator 21 which generates a pilot carrier wave at the burst frequency. The frequency of the pilot carrier wave is doubled, 26, and phase inverted, 30, every line and the resulting oscillations are modulated, 32, by the brightness and colour carrier information on line 17. After passing through a vestigial sideband filter 341 and being added, 25, to the pilot carrier wave, the signal transmitted over conductors 2, 3 comprises a brightness information carrier component having a carrier wave 8, a suppressed carrier wave colour sub-carrier information component in respect of the first and second colour carrier information signals, having a suppressed sub-carrier wave 10, and a pilot carrier wave 12, the phase of the brightness and first colour information components being reversed at line frequency. The frequencies of the pilot carrier wave 12, the carrier wave 8 and the suppressed sub-carrier wave 10 are related in the ratio 1:2:3. In the receiver 6 the signals from conductors 2, 3 are fed to a bandpass filter 37 which selects the brightness and colour information components. These signals are amplified, 38, and demodulated by an envlope detector 39 to produce on line 40 a brightness information signal of video frequency. The suppressed carrier wave colour sub-carrier information signals are derived from the output of detector 39 by means of a band pass filter 41 and two synchronous detectors 42 and 43. The second colour information signal is obtained from detector 42 by means of a re-insertion carrier wave of constant phase derived from the pilot carrier wave by means of a narrow band pass filter 44 and amplifier 45. The first colour information signal is obtained from detector 43 by means of a reinsertion carrier wave the phase of which is reversed at line frequency derived from a balanced mixer 48 fed with the amplified pilot carrier wave and the brightness carrier wave, the phase of which is reversed at line frequency. The brightness carrier wave is derived from the output of amplifier 38 through a narrow band pass filter 49.

Title: Antibiotic complex taimycine and method for the preparation thereof
IPC: A61K35/66
Filed: 1968-06-06
Abstract: An antibiotic complex Taimycine (having components A, B and C) and salts thereof, are produced by cultivating a Taimycine-producing strain of Streptomyces michiganensis var. amylolyticus, e.g. IMI 131670, in a liquid culture medium containing an assimilable source of carbon, an assimilable source of nitrogen and mineral salts. The antibiotic complex is obtained by filtering the broth through a siliceous adsorbent, extracting the cake several times with methanol, concentrating the extract and centrifuging the crude antibiotic precipitate. The supernatant is adjusted to pH 5.8 to 6.2, extracted with petroleum ether to remove impurities and then with chloroform. Petroleum ether is added to the chloroform extract to ppte. further crude Taimycine. The crude is subjected to chromatography on silicic acid using a solution of the crude in the lower layer of a CHCCl 3 : Cll 4 CH 3 OH: H 2 O (3: 2: 4: 1) mixture and eluting with chloroform-ethanol mixtures having increasing percentages of ethanol. The fractions are concentrated, diluted with water, adjusted to pH 6.0 and concentrated to precipitate the sodium salts of Taimycine A, B and C. Taimycine C is further purified by crystallization from methanol/water. Taimycine B and A are further purified by counter-current distribution using the solvent system chloroform/carbon tetrachloride/methanol/water. The free acid form is obtained by treating a solution in chloroform and ethanol with acetic acid and then water. The aqueous layer is extracted with chloroform and the extract concentrated to give a crystalline precipitate. The sodium salts of Taimycine A, B and C are white amorphous powders, soluble in dimethyl formamide, dimethyl sulphoxide and dioxan, in aqueous alcohols and aqueous acetone sparingly soluble in alcohols, chloroform, acetone and benzole insoluble in water and petroleum ether. Taimycine has antihelmintic and antiprotozoal properties. A pharmaceutical composition comprises one or more Taimycine antibiotics and a carrier.

Title: Fluid energy drying mill
IPC: F26B17/10
Filed: 1970-07-09
Abstract: A fluid energy drying mill wherein the material to be dried is a liquid slurry of solid particles or of solids in solution. The slurry, upon being fed into the mill is immediately atomized and flash-dried, the atomization being accomplished by high pressure, high velocity gaseous fluid jets, while the flash-drying is effected by very hot, low pressure, gaseous fluid jets. The hot gaseous fluid jets comprise a plurality of gaseous fluid streams which enter from at least four different sides surrounding the feed inlet and converge at a focal point downstream of the inlet whereby the hot gaseous fluid both encompasses the fed material and concentrates its heat energy in the path of the fed material. The flash-dried particles are then centrifugally passed through the curved portion of the mill and centrifugally exhausted from the mill during their passage. Optionally, by-pass ducts may be provided between the downstack portion of the mill and the inlet chamber where atomization and flash-drying takes place whereby vapors from the downstack are used to break any vacuum in the inlet chamber and may also be used as a tempering means to avoid case hardening of the particles.
