Title: Improvements in or relating to electro-magnetic transducers
IPC: G01D5/20
Filed: 1960-03-16
Abstract: 950,842. Transducers. PHILIPS ELECTRICAL INDUSTRIES Ltd. March 16, 1960 [March 19, 1959], No. 9285/60. Heading H4J. In a balanced armature transducer any unbalance in the magnetic system resulting in flux flowing in the armature in the rest condition is removed by providing a high-reluctance shunt to at least one air gap so as to reduce the armature flux to zero. In each of the transducers of Figs. 1 and 2 a permanent magnet 1 surrounded by a winding 12 has soft iron polepieces 2, 3 with extensions 14, 15, between the free ends of which is a soft iron armature 4, one end of which is clamped in the base-plate of a U-shaped soft iron yoke 5. If an alternating current is applied to the winding 12, any unbalance will result in the induction of an alternating voltage in the coil 10 surrounding the armature 4 which will be indicated on the meter 11. The transducer may be balanced by applying to one of the two limbs of the yoke 5 one or more layers 13a (Fig. 1) of a cement, laquer, or glue, which has been made mag netically conductive by adding, for example, carbonyl iron powder. Alternatively, a magnetically conductive strip 13b (Fig. 2) may be provided at a distance from the limb concerned. In a modification, flexible magnetically conductive strips or wires (not shown) may be secured one to each of the limbs of the yoke 5 or one to each of the extensions 14, 15, the distance of one of these strips or wires from the limb on the other side of the air gap being varied until a balance is established.

Title: Register indicator device
Inventor: WEBB DUDLEY ERNEST
IPC: B41F13/02
Filed: 1963-03-08
Abstract: 1,068,904. Photo-electric registration of multi colour printing. TIMSONS Ltd. June 8, 1964 [March 8, 1963], No. 9424/63. Heading G1A. [Also in Division H3] Register errors between a moving web and a machine performing operations on the web are detected by generating trains of pulses corresponding to the movement of the web and the machine, the frequency of said pulses differing by a small integral factor, prolonging the pulses of the higher frequency train to a repetition interval equal to the interval between the pulses at the lower frequency, prolonging the lower frequency pulses to a duration somewhat less than the repetition interval of the other series of prolonged pulses, and applying the two series of prolonged pulses to gate and amplifier circuits the output of which indicates the phase relationship between the prolonged pulses and hence the register condition of the web and the machine. Photo-cells 10, 10' detect marks on the web and a machine member respectively to produce trains of pulses which are shaped to a standard amplitude regardless of the machine speed by Schmidt trigger circuits. The pulses from photo-cell 10' are at twice the frequency of those from 10 and are fed to a bi-stable multivibrator divide by two circuit, 3, to produce a train of square wave pulses of length equal to the interval between the original pulses. Circuit 3 also includes a monostable multivibrator which resets the divide by two circuit after a predetermined time should a random pulse make it out of step. The pulses from photocell 10 are lengthened by a flip-flop 4 to a length between one and two times the length of pulses from circuit 3. Two outputs of opposite polarity are taken from flip-flop 4 and fed to coincidence gates 5a and 5b. The other input to gates 5a and 5b is the square wave train from circuit 3. Gates 5a and 5b give output pulses of length equal to the overlap of the input pulses, and these outputs after amplification at 5c and 5d are fed to a meter 5e which indicates the difference in mean currents from the gates 5a and 5b which depends on the phase of pulse trains from flip-flop 4 relative to the pulse train from circuit 3. The current difference is indicative in magnitude and sense of the register error between the moving web and the machine, and an output may be taken at x, y for automatic register correction.

Filed: 1918-06-14
Abstract: 122,356. Petersen, J. P. June 14, 1918. Selvedges, forming. - In a loom for weaving Madras curtains and fabrics with like pattern effects, there is arranged on each side of the loom a spring - actuated rocking lever of the kind that is lowered to catch the weft at the selvedge around its pointed end and is raised positively by a part on the lay as the weft is beaten up, and the rocking lever is acted upon by the drop box so that, when the drop box is lowered to put the pattern weft shuttle out of action, the rocking lever is rendered inoperative. The invention obviates the use of catching-threads at the selvedges. The rocking lever 1 is slidably and pivotally mounted on a pin 3, which passes through a slot 2 in the lever, and the upper end of the lever is adjustably connected by a rod 7 to a sleeve 8 fixed to a shaft 11. On this shaft are secured an arm 12 and a pulley connected by a spring 16 to the loom frame 4, the spring tending to keep the lever 1 in the position shown so that the weft is looped at the selvedge around the pointed end of the lever. As the lay 20 moves forwards, a curved arm 19 thereon acts on the arm 12 to raise the lever and allow the weft to be beaten up. A pulley 14 on the shaft 11 is connected by a belt or cord 26 to a part 18 on the drop box 10, so that, when the shuttle in the highest box is in action, the lever 1 is rendered inoperative. The band 26 may be adjusted to render the lever 1 inoperative also when the second or other box is level with the rail. The catching motion may be put out of action by removing the spring 16.

Title: Improvements in or relating to the recovery of the antibiotic oxytetracycline
Filed: 1951-04-27
Abstract: Oxytetracycline (terramycin) is purified or isolated from a fermentation broth as a metal complex, which may then be converted into any desired therapeutic form of oxytetracycline, by adding to an aqueous solution of pH 7.0 to 10.0 at least one of the metals barium, strontium and calcium, and at least one of the metals magnesium, zinc, beryllium, cadmium and mercury.  Specified complexes are of calcium-magnesium, barium - magnesium and barium - zinc; the barium-magnesium complex having the lowest solubility. In the case of a fermentation broth, which normally contains sufficient calcium and magnesium ions, it is preferred to adjust the pH of the filtered broth to 8.0 to 9.0 and to add barium ions, e.g. barium chloride. Iron, chromium and copper impurities are removed by dissolving the complex in dilute acid, e.g. sulphuric acid, adding a soluble ferrocyanide, e.g. potassium ferrocyanide, to precipitate the iron &c. and removing excess ferrocyanide by the addition of a soluble zinc or zirconium salt.  Oxytetracycline is obtained by adjusting the filtrate to pH 7.0 with alkali.  The precipitate is dissolved in methanol and concentrated hydrochloric acid added to produce the hydrochloride, which may be given a further purification with activated carbon. Specification 684,417 is referred to.
