Title: Signal transmission system
IPC: G10L25/00
Filed: 1964-03-05
Abstract: 1,039,822. Transmission systems; pulse modulation systems. INTERNATIONAL BUSINESS MACHINES CORPORATION. March 5, 1964 [March 18, 1963], No. 9285/64. Headings H4L and H4R. A complex wave, e.g. speech, is transmitted by adding to the wave a constant amplitude reference signal of a frequency outside the frequency band of the complex wave and limiting the resulting signal to obtain a rectangular waveform of constant amplitude and having zero crossings corresponding to the zero crossings of the sum signal. The resulting rectangular wave has the same power-frequency distribution as the original waves but, due to the limiting, the total power has been made constant. At the receiver the complex wave band and the reference signal band are separated and the level of the complex waveband adjusted in accordance with the change in level of the reference signal band so as to restore the original power level to the complex waveband and thus restore the complex wave to its original form. Fig. 1 shows a block diagram of the system in which a signal from the transducer 10 is fed via a pre-emphasis network 12 and a band-pass filter 14 to a summing amplifier 18 where it is added to a reference signal from generator 16. The sum signal may then be modulated to a higher frequency band in device 20 in order that after clipping in limiter 22 the modulation products, which might cause distortion in the speech, lie outside the speech frequency band. The resulting clipped waveform is transmitted to the receiver by means 24 which may include a demodulator if the signal was modulated before clipping. The transmission may be by amplitude modulation of a carrier or the signal may be transmitted as a pulse train. At the receiver the original speech signal is recovered by decoder 26 and de-emphasis network 28. Three forms of decoder are described; in one, Fig. 2, the speech components are separated from the sum signal by band-pass filter 34 and applied to the dividend input of a divider circuit 38, the reference signal is separated by the band-pass filter 32, its envelope detected, and the resulting signal applied to the divisor input of the dividing circuit the output from which, after de-emphasis, is a replica of the original speech. In a second embodiment, Fig. 3, the speech components from filter 40 are applied to a variablegain amplifier, 42, the gain of which is controlled in accordance with the deviations of the level of the received reference signal components from envelope detector 46 as compared with a comparison reference level from generator 48 as determined in difference amplifier 50. In an alternative form, Fig. 4 (not shown), the variable gain amplifier acts on the sum signal which is then applied to the speech component and reference component band-pass filters, the output from the reference component filter being fed back to control the amplifier gain to tend to maintain the reference component level constant, the signal component then being restored to its original form.

Title: Improvements relating to the production of tetracycline
IPC: F16H27/08
Filed: 1955-04-01
Abstract: A substantially chloride-free nutrient medium for the production of tetracycline by biosynthesis is prepared by treating an aqueous solution of chloride-containing nutrient material with silver or mercurous ions at a pH below about 7 and separating from said aqueous solution the silver or mercurous chloride thus formed.  The pH is preferably adjusted to below pH 4.0 by any inorganic acid except hydrochloric acid.  Specified silver salts are the nitrate, acetate, benzoate, propionate, chlorate, perchlorate, lactate and sulphate. Specified mercury salts are the acetate, benzoate, chlorate, nitrate and sulphate. The medium treated may be the whole fermentation broth but is preferably only those components of the broth which contain chloride ions, e.g. corn steep liquor.  Excess silver or mercurous ions are removed from the treated solution by hydrogen sulphide or sulphides such as ammonium sulphide, sodium sulphide or potassium sulphide at a pH below 7.0.  Excess hydrogen sulphide may be removed by passing nitrogen through the liquid in vacuo.  Any phosphates and heavy metals removed by the above processes should be replaced.  The nutrient medium for the production of tetracycline is otherwise the usual medium containing a source of (a) carbon, e.g. corn steep liquor, soy bean meal, fish meal, peanut meal, sugar, starch, glucose, maltose, dextrose, sugar alcohols and citric acid; (b) nitrogen, e.g. corn steep liquor, soybean meal, fish meal, meal meal, hydrolysed casein, amino acids, ammonium salts, nitrates and urea; (c) inorganic salts; and (d) trace elements.  The micro-organism is any tetracycline-producing micro-organism, e.g. S. aureofaciens.

Title: Improvements in automatic electric furnace regulators of the current-voltage balancetype
IPC: H05B7/152
Filed: 1958-03-26
Abstract: 817,618. Automatic control systems for electrode furnaces. SHAWINIGAN CHEMICALS Ltd. March 26, 1958 [April 6, 1957], No. 9656/58. Class 38 (4). Each electrode of a multi-electrode furnace is automatically positioned to maintain a balance between electrode current and electrode position as determined by the variation of an impedance adjusted by movement of the electrode. In Fig. 3, one field 14-3 of an amplidyne generator 6-3 is energized through a rectifier 40 and a transformer 22 in dependence on the current supplied to one electrode 3 of a three-phase furnace. The energization of an opposing generator field winding 15-3 from a D.C. source RVDC is made dependent on electrode position by a potentiometer 11-3 which is adjusted by movements of the electrode in a vertical direction. Unbalance between these field windings of generator 6-3 produces an output to cause a D.C. motor M-3 to raise or lower the electrode as required to restore balance. Similar control systems (not shown) are provided for the other furnace electrodes 1 and 2 and the field windings 15-1, 15-2 respectively associated with the generators of these systems are supplied from D.C. source RVDC in series with field winding 15-3 so that movement of any electrode in one direction is accompanied by movement of the other electrodes in the opposite direction. Initial setting up is facilitated by potentiometers 17-3, 18, 23, and adjustable coupling is also provided between electrode 3 and potentiometer 11-3. For starting and until the charge has melted a changeover switch (not shown), is operated to disconnect field winding 15-3 at A 1 , B 1  and connect it at A 2 , B 2  with a voltage dependent on electrode voltage obtained through a rectifier 50. In a modification, Fig. 1 (not shown), the currents to be balanced differentially energize A.C. operated two-way electromagnetic relays controlling reversible servomotors adjusting electrode position. In this arrangement a time delay relay ensures a minimum operating period for the servomotor to prevent chattering and a pair of limit switches are associated with each electrode.
Patent GB-1450757-A (GB)
Title: Timed signal generating apparatus
IPC: G06F1/02
Filed: 1975-03-07
Abstract: 1450757 Counting apparatus INTERNATIONAL BUSINESS MACHINES CORP 7 March 1975 [29 April 1974] 9718/75 Heading G4D Apparatus is disclosed for producing two pulse trains of equal repetition rate but shifted in phase by an amount determined by an applied digital number. In an example clock 1 delivers a pulse every 9 nanosecs to a counter 4 of capacity 8 and a divide by 8 circuit 7 while clock 2, when synchronised, delivers a pulse every 8 n. sees to a counter 5 of capacity 9 and a divide by 9 circuit 8. Thus each divider 7, 8 delivers a pulse every 72 n.secs; any error in phase between the two pulses is employed by feedback loop 10a to correct the phase of clock 2. So in every period of 72 n.secs clock 1 delivers 8 pulses and clock 2 delivers 9 pulses to the counters 4, 5 respectively. Comparators 3, 6 compare the counts with the binary number applied to terminals D1, D2, D4 and issue pulses P 1 , P 2  when equality is detected. Effectively the counters 4, 5 and comparators 3, 6 act to select the 1st to 7th pulses in each 72 n. sec. period of each train according to which of the numbers 1 to 7 in binary is applied at terminals D1-D4. The resulting pair of pulses is separated by 1-7 n. secs. accordingly (see Fig. 1B). In a modification (Fig. 2 not shown) the binary numbers applied to the two comparators 3, 6 are not the same. They are derived instead from a read only memory to which a seven bit binary number is applied to select the delay. The ROM delivers numbers which select any one of the pulses in each train thus allowing any delay between 0 and 71 n. sees. to be selected. Different clocks 1, 2; counters 4, 5; dividers 7, 8 may be employed to derive pulses at different rates with different phase shifts. Detailed logic circuits are described.

Title: Improvements in or relating to shuttle changing mechanisms
IPC: D03D45/20
Filed: 1953-04-10
Abstract: 743,863. Automatic weft replenishing looms. BUTIN, E. A. April 10, 1953 [April 18, 1952], No. 9817/53. Class 142 (2). In a loom with change boxes and a multicompartment magazine, weft exhaustion is indicated by a weft feeler, and lever mechanism stores the indication until a box chain brings the exhausted shuttle to the operative position when a full shuttle is released from the magazine. A barrel 27 having four studs 32 corresponding to four change boxes is turned by a linkage 33, 101, 102 in step with the movement of the boxes. When a feeler 3 indicates weft exhaustion, a cord 11 is pulled and swings a frame 29 carrying the drum 27<SP>1</SP>. One of the studs engages one of four arms 45 and moves a corresponding lever 37 to the left releasing a further lever 38 which falls on to a control lever 39. The need for replenishment is now stored until the box chain 35 lifts one end 107 of the control lever and the other end 56 drops allowing the lever 38 to fall further and uncover a notch 48 on a trip lever. A cam 28 continuously rotated by a chain 34 from the loom crank-shaft rocks a lever 51 carrying a pawl 42. When the notch 48 is uncovered, the pawl engages the notch and rocks a lever 109 connected by one of four cables 6-9 to the corresponding shoot of the magazine. As the lever 109 turns, it strikes a bar 53 extending behind the four levers 109 and pulls a cable 12 which brings the whole replenishment mechanism into operation. The bar 53 is carried by a lever 52 having an extension 110 which resets the various levers. Specifications 644,363 and 669,326 are referred to.
