Title: A one-bit magnetic storage device and matrix
IPC: G11C7/00
Filed: 1963-02-01
Abstract: 1,024,664. Magnetic storage elements. NATIONAL CASH REGISTER CO. Feb. 1, 1963 [March 8, 1962], No. 4201/63. Heading H3B. A storage element arranged to minimize read-out noise comprises two conductors a portion of one or both of which is coated with a magnetic thin film, coils being provided around both the coated and the uncoated portions. In one embodiment, Fig. 1, both conductors 10, 11 have a thin film coating 12, 13 and are connected to writing terminals X, X<SP>1</SP>. The coils 14-17 provided around the conductors are connected in series-parallel to a write/read terminal Y, each conductor having one coil 14 or 17 wound around the magnetic coating in one sense and a coil 16 or 15 wound around the uncoated portion in the other sense. The magnetic coatings have an easy magnetization axis parallel to the axis of the respective conductor. To store a binary one, positive and negative pulses are applied coincidently to terminal X and X<SP>1</SP> respectively, and after a short delay a coincident positive pulse is applied to terminal Y. To store a binary zero the pulse polarities applied to the respective terminals X, X<SP>1</SP> and Y are negative, positive and negative. Non-destructive readout is effected by applying a positive pulse to terminal X<SP>1</SP> in coincidence with a negative pulse applied to terminal X, the arrangement of the coils 14-17 being such that inductively and capacitively coupled noise is neutralized. In a modification, Fig. 2, conductor 10 only has a thin film coating 18, and a single coil 19 serving as a sense winding encircles both conductors. Operation is substantially the same as previously described. A further embodiment is shown in Fig. 3 in which the two conductors 10, 11 are connected to terminal Y and constitute the sense winding, and the two coils 14, 16 and 15, 17 in respective conductors are connected in opposed series relationship to respective writing terminals X and X<SP>1</SP>. In this case the mode of operation is the same as previously described but the information stored is destructively read-out. A storage matrix using the Fig. 1 arrangement of storage elements is shown in Fig. 5, each conductor 10a-11n having discrete magnetic thin film coatings 12a-13n along its length. The coils 13a-17n associated with a column of storage elements are connected in two series-parallel paths. The conductors are selectively energized by write/ read drivers 22, 23 and the coils of a column of storage elements are connected selectively by switches SW1-SW5 to a driver 21 or a detection and utilization circuit 20.

Abstract: 138,911. Soc. Anon. des Etablissements A. Olier. Feb. 11, 1919, [Convention date]. Void [Published under Sect. 91 of the Act]. Materials, fibrous; pulp, preparation of.-In the preparation of cellulose for paper-making from fibrous plants such as maize, alfa, dwarf-palm, papyrus, and urena lobata, the stalks and leaves are cut up, crushed, and washed, and then treated by steam at 2-3 kgs. pressure for one hour in a digester, condensation water being drained away and taking with it parenchymatous cellulose and soluble matters such as gums and pectates. The cellulose fibres swell up, and the cement is partly dissolved. The drain-cock is then closed, and 12 per cent caustic soda introduced and circulated by a Koerting injector, or by using a digester of the vomiting type, or by other means, the operation being conducted for 3 hours at 2-3 kgs. pressure. The product 's washed, broken in a beating-engine or small mill, and bleached, and may be used for half-pulp paper such as packing-paper. Semi-chemical pulp may be obtained by substituting slaked fat lime for the caustic soda, and, by partial bleaching of the half-pulp so produced, a pulp suitable for newspapers is obtained. Alkali materials may be recovered by evaporation and re-causticized.

Title: Remotely controlled blasting machine
IPC: F42D1/05
Filed: 1973-01-26
Abstract: 1423303 Detonating remote blasting, caps BENDIX CORP 26 Jan 1973. [2 Feb 1972] 4216/73 Heading H2H A circuit arrangement for detonating remote blasting caps comprises a first circuit 20. including a capacitor 160 which is dischargeable through the blasting caps when the capacitor charge reaches a predetermined level and a second circuit 10 which supplies electrical energy to the first circuit, the second circuit including a device 118 which indicates when the capacitor charge is approaching the predetermined level The circuit 20, which has terminals 190 for connection to the blasting caps, is connected by wires 21, 22 to the remote circuit 10. A switch 116 and resistors 111-115 enable the circuit resistance to be maintained constant when using wires 21, 22 of lengths up to 5000 feet. On application of A.C. to input terminals 131 the capacitor 160 is charged via a transformer 151, a capacitor 122 also charging to a voltage proportional to that across the capacitor 160. As the voltage across the capacitor 160 approaches the breakdown potential of a spark gap device 170, the voltage across the capacitor 122 becomes sufficient to illuminate the device 118 thereby warning an operation of the imminent discharge of the capacitor 160. The operator may open a switch 135 to allow discharge of the capacitor 160 through a resistor 161. Alternatively when the capacitor 160 charges to the predetermined level, the breakdown of the device 170 supplies trigger pulses to a spark gap device 180 to enable the discharge of the capacitor 160 into the blasting caps.

Abstract: 195,496. Western Electric Co., Ltd., (Western Electric Co., Inc.). Feb. 14, 1922. Artificial lines and balancing networks for telephone systems.-A network a b c d, Fig. 1, for insertion in a transmission line, comprises series impedance elements of value n/2 J1 and shunt impedance elements of value n/2 J2 connected as shown, n being any real number and J1, J2, respectively, the values of the series impedance and shunt impedance per unit length of the line.. The series elements comprise resistances R and inductances L, Fig. 2, and the shunt elements comprise capacities n/2 C and conductances n/2 G. Such a network has the property that its impedance at all frequencies is equal to the characteristic impedance of the line, and it may thus be introduced into a line without changing its characteristic impedance or causing reflection effects. The network may be used for introducing apparatus, for example, a relay, Fig. 3, intoa line, similar parts x being inserted in each of the series branches and additional inductance orresistance being added to obtain the same proportion of each as is present in the quantity J1. If the apparatus has a capacity effect, it may be ineluded in one or both of the shunt branches. The network may also be used for obtaining a change of phase in the current flowing over a line, whilst a number of such networks serially-arranged may constitute an artificial line. simulating an actual line. The Specification contains a mathematical investigation into the properties of the network, and derives a formula giving the value of n necessary to produce a desired angle of phaseshift. Part of the inductances n/2 L may be made up of mutual inductances between the coils in the opposite branches.

Title: Process and apparatus for disinfecting natural water using silver ions
IPC: C02F1/50
Filed: 1976-02-20
Abstract: Water is fed to a unit in which the chlorides are removed or significantly reduced. 600 to 1000  mu g/l of silver ions are then added to the water, which quantity is much higher than the 50  mu g/l permissible according to the "Environmental Protection Agency Standard for Drinking Water". Part of the water is then treated with a mixed resin bed to partially deionise it, the natural minerals being thus retained in the other part. The use of an excess quantity of silver ions significantly reduces the holding time of the water to be purified.
