Title: Electrical apparatus incorporating super conductors
IPC: G11C19/32
Filed: 1964-07-01
Abstract: 1,064,796. Digital data storage. RADIO CORPORATION OF AMERICA. July 1, 1964 [Aug. 16, 1963], No. 27239/64. Headings G4C and G4H: [Also in Divisions H1, H2 and H3] A superconducting device comprises a length or annulus of superconducting material, means for establishing a persistent current in a restricted area of the material and control means coupled, to said material for causing the restricted area to move along the length of the superconductor material. The speed and motion of the restricted area its dependent upon the magnitude and duration of the control means and thus the restricted area may be controllably moved along. The control means may be electrical or magnetic. In the case of magnetic control, it is by means of the magnetic fields produced by applying currents to leads adjacent the superconducting material. A portion 15 of a superconducting tin film 7, adjacent a lead film 2 is driven from its superconducting state to its normal state by a current from a small exciting coil thereby establishing a persistent circulating current 10, with its associated tapped magnetic flux 12 which passes through the normal portion 15 and a copper film 3. If control current 14 is applied perpendicular to the films 1, 2 and 3, then the normal area will move along the lead-tin interface. In another embodiment, Fig. 3, annular strips 5; 6 and 7 of Sn, Pb and Cu respectively are situated on a drum of insulating material having a tin face 24 and an opposite face of tin or copper. A control: current is applied at 20 and grounded at 26. A stationary drum memory is formed by writing information on -the cylindrical surface using write head 28 and reading it by head 30, although a single write-read head may be used. The, control current may be pulse-wise, thus each " bit " of, information moves . a fixed distance and remains there until the, next pulse. Thus the device may be used as at shift register. Information stored may be erased by applying a current pulse of opposite polarity to reduce the persistent current to zero or a small value. Other materials suitable as superconductors are In.Nb, Ta, ,V and alloys thereof whilst Cu may be replaced by Ag .or Au. The device may be used as an analogue-to-pulse. count converter by applying a current pulse to lead 22 of amplitude proportional to the analogue quantity but of fixed duration and one or more equi-spaced persistent areas to the superconductors ,in which case, the frequency of the alternating current at the read head is proportional to the analogue quantity. On a multi-track drum, one or more of the tracks may be used for timing in a manner analogous to the clock pulse tracks on a magnetic drum.

Title: An improved mole drain plough
IPC: E02F5/10
Filed: 1926-11-01
Abstract: 270,565. Jensen, H. R. Nov. 1, 1926. Mole-drain ploughs; tools; travelling gear.-A mole plough comprises two parallel angle irons 1, two front curved and dished runners 4, a rear adjustable blade 7 mounted between the angle irons, a mole 10 with a pivoted extension 11, and an adjustable stay member 14 pivoted between the angle irons 1 and adapted to engage with notches at the upper end of the blade member 7. The angle-iron beam 1 is provided with a draught link 5 and a lifting handle 16. The blade 7 is mounted on a pivot bolt 8 and is adjustable angularly and vertically. The upper end of its cutting-edge is curved forward and at its lower end the mole 10 is mounted at an angle. The pivoted extension 11 of the mole has a, hole 13 through it to admit air to the drain. The stay 14 is tubular and is provided with a handle 17 by which it may be moved to hold the blade 7 at the required inclination. Its lower end may be connected to a bellcrank lever provided with a locking quadrant. By means of this lever the blade 7 may be inclined in such a way as to vary the level of the drain or so as to cause the mole to come to the surface as the implement moves forward. When the stay 14 is disengaged the top end of the blade tips forward and catches in the ground, thus turning the blade about the bolt 8 until the mole rests on the top of the beam 1. The rounded part 28 of the blade then acts as a runner.

Filed: 1955-09-27
Abstract: 771,101. Exchange systems. SIEMENS & HALSKE AKT.-GES. Sept. 27, 1955 [Sept. 27, 1954], No. 27501/55. Class 40 (4). In an arrangement for indicating calls at manual positions in batches, the calling relays C (not shown) control auxiliary relays D which when operated lock and light calling lamps Al and the operation of a predetermined number of D relays energizes a relay S which prevents the operation of any further D relays until the first batch of calls has been dealt with. The number of calls required to energize relay S depends on a tapped shunt resistance Wi which is cut out upon energization so that the relay holds until all the D relays restore. Further incoming calls are indicated by lamps Wl at a supervisor's position until relay S restores, when the corresponding lamps Al are substituted. The resistance Wi may be adjusted manually in accordance with the traffic conditions or automatically by a timing device associated with relay S.

Title: Improvements in or relating to method of preparing crystalline alkali metal phosphates
IPC: C01B25/41
Filed: 1956-09-10
Abstract: Alkali metal polyphosphates are prepared by reacting an aqueous alkali metal orthophosphate with a soluble alkaline earth metal compound, separating the precipitated alkaline earth metal phosphate, concentrating the solution having an increased alkali metal: P2O5 ratio to form a paste and heating the paste at 800-1250 DEG  F. for 30-90 minutes.  It is preferred to form the initial orthophosphate solution by reacting an impure phosphoric acid (produced e.g. from rock phosphate with sulphuric acid) with an alkali metal salt, e.g. a chloride or sulphate, evaporating to dryness, heating at 1400-2000 DEG  F., quenching in water and hydrolysing the solution of quenched material (metaphosphate) e.g. at 150-250 DEG  C. and 100-200 p.s.i. Alkali metals specified are lithium, sodium and potassium, and mixtures thereof; alkaline earth metal compounds specified are the oxides, hydroxides, nitrates, acetates and formates of magnesium, calcium, strontium and barium.  A ratio of alkali metal oxide: phosphorus pentoxide between 0.9 and 1.25 is preferred in the orthophosphate solution, and the alkaline earth metal compound may be added so as to leave a ratio of 1.5-1.75 in the solution, which ultimately leads to tripolyphosphate production.  The reaction temperature may be between 70 DEG  and 100 DEG  C. or above; when using calcium hydroxide as precipitant, dicalcium phosphate is formed above 100 DEG  C. and tricalcium phosphate below 100 DEG  C.

Title: Anti-hunt means for electric motor positioning system

IPC: G05D3/12
Filed: 1954-09-28
Abstract: 753,816. Control of several motors. BOEING AIRPLANE CO. Sept. 28, 1954, No. 28003/54. Class 38(3) In a servo system two motors 10, 20, are energized simultaneously in accordance with a positional error signal, and, whereas the motor 10 provides the greater part of the drive torque for a reversible load shaft 8, the motor 20 develops little momentum and affords only sufficient torque to cause a worm 22, which engages wheel 24, to follow the position of the driven shaft. When the energization of the two motors terminates as the shaft 8 reaches its desired position, the motor 20 stops abrubtly and, because of the unilateral nature of the worm-wheel drive, the braking of the shaft is substantially instantaneous. The momentum of the motor 10 is absorbed in a flexible coupling 14 which is connected to the motor through speed reduction gearing and allows the motor to over-run the driven shaft so that over-shooting of the desired stopping-position is prevented. A follow-up device 30, such as a potentiometer produces a signal representing the actual position of the shaft 8, and this signal is compared with one representing the desired position of the shaft. The difference of these two signals is amplified and the motors 10, 20, are so energized that the positional error signal is reduced to zero by re-adjustment of the follow-up device.
