Title: Patching a communication line using magneto-inductive signals
Inventor: LOCKE EVAN
IPC: G08C17/04
Filed: 2009-02-05
Abstract: A system and method for patching a break in a communication line using magneto-inductive signals. The magneto-inductive signals are modulated data signals having a carrier frequency below 10 kHz. Multiple magneto-inductive communication units 32, 34 are placed in spaced relation on a communication line 12. A break in the communication line 12 is detected between two of the units 32, 34 and the units 32, 34 establish a magneto-inductive link 150 to relay communication signals from the communication line 12, thereby patching the break. A transmitting magneto-inductive unit 32 comprises a break detection module 126, an interface circuit 122 connected to the communication line 12 and an antenna 114 having at least one loop for creating a magnetic field 150. The interface circuit 122 has a modem for demodulating a communication signal from the line 12 to obtain a data signal, which a transmitting or transceiving module 116 in the unit 32 modulates at a carrier frequency below 10kHz to drive the antenna loop of the unit 32 to create a magnetic field 150. A receiving magneto-inductive unit 34 comprises a break detection module 142, an interface circuit 144 connected to the communication line 12 and an antenna 134 having at least one loop for coupling to the magnetic field 150. A receiving or transceiving module 136 recovers the data signal from the received signal and the interface circuit 144 has a modem that modulates the data signal for transmission on the communication line 12. The magneto-inductive signal may be generated when either unit 32, 34 detects a break in the line 12 between them, for example, by determining that no keepalive signal or no response to a check break signal has been received within a predetermined time.

[Class 38 (i)] A plug for a two-part coupling has the contact pins adjustable in spacing so as to fit two and three pole outlet sockets of various sizes and current ratings. In one embodiment, Figs. 8 and 9, the live pins 22, 23 are eccentrically mounted on metal disc 29 which are fixed between insulating discs 30 and 30a. Discs 30a act as journals in holes in the top cover 62 of the body 21, whilst discs 30 have toothed peripheries which are in mesh so that rotation of either disc will alter the relative spacing of the live pins. Connections to the pins are made through fuses 26. The earth pin is mounted on a plunger held forward by a spring 65 which also acts as an electrical connection. The plunger is locked forward when necessary by a bar 67 co-operating with a cam 66 affixed to one of the discs 30. All the pins are fitted with expansible contact blades located by pins 61 'in inclined slots, and urged forward and outward by springs 73, or spring 65. In another embodiment, Figs. 1 and 13 (not shown), one live pin is mounted on a spring-loaded transverse sliding bar, arranged to be operated from outside the body of the connector. In a further embodiment, Fig. 4 (not shown), a tee-shaped plunger is used to urge both live pins along slots in the fuse of the plug body that are directed radially towards the earth pin. In any embodiment, the pins may be reversible in a screw or bayonet mounting so as to give a smaller diameter at one end than the other; or the pins may be fitted with enlarging sleeves normally housed within the body; or with resilient contact tips. Any of the plugs may be combined with outlet sockets to form adaptors. The first Provisional Specification also states that the pins should be grooved at the base, and that a switch or circuit breaker may be incorporated. The second Provisional Specification also discloses, plugs having one pin mountable in two alternative housings, whilst the second pin may be resiliently mounted; plugs in which each pin comprises a large and a small diameter pin joined at right angles and pivoted so that either end can be turned up for use. The smaller pins are offset from the larger so as to have a smaller spacing between centres. A separate reversible carrier is also disclosed carrying double-ended pins of different diameters, contact being established with blades mounted within the plug body.

Title: Refractory products and process of making the same
IPC: C04B35/01
Filed: 1938-04-04
Abstract: Refractory material capable of withstanding the corrosive action of molten glass, suitable, e.g. for pots and crucibles, tank furnaces, and feeder orifice rings, is made by moulding and firing stannic oxide, e.g. putty powder.  The shrinkage during and after firing is relatively large and slow.  This may be accelerated by adding a small amount of a compound of cobalt, nickel, iron, copper, silver, gold, or manganese.  To reduce shrinkage, the raw mixture for the finished article may consist, up to 95 per cent, of a prefired grog.  In an example, 900 grams of stannic oxide of which 30 per cent is grog, is mixed with 140 cc. of water and 18 gms. of cupric chloride.  The mixture is moulded at a pressure of 10,000 lb. per sq. in. in steel moulds for about 5 mins. and is fired in an oxidizing atmosphere to a temperature of 1300-1500 DEG  C.  The temperature is reached in increments of 200 DEG  C., each temperature being maintained for one hour.  Instead of making the whole article of stannic oxide, a veneer of the material may be fired on to ordinary clay articles such as tank blocks, bricks and crucibles.  The surface of the article may be coated with a high melting point glass, e.g. a borosilicate glass. This may be done by coating the raw article with ground glass and firing, or, preferably, by applying a layer of ground glass to the fired refractory article and reheating to 1100 DEG  C.

Patent GB-714066-A (GB)
Title: Improvements in the production of benzine
IPC: C10G47/00
Filed: 1951-05-03
Abstract: Benzine is produced from mineral or shale oil (which may have been freed from benzine and middle oil initially present) by a two-stage hydrogenation.  In the first stage the liquid materials are treated with hydrogen at a temperature of 450 DEG C. to 550 DEG C. and a pressure of at least 200 atmospheres so that more than 30 per cent. of middle oil is freshly formed.  The product (if desired after separation of benzine), with 1-5 cubic metres of hydrogen/kgm. of oil is then passed at 400-550 DEG C. and 200-800 atmospheres, with a throughput of 0.3-1.5 kgms./litre of catalyst volume/hour over an acid activated silicate or alumina carrier substance provided with a small amount of a molybdenum or tungsten compound and if desired at least one compound of chromium-zinc, iron, nickel or cobalt.  The high-boiling fraction of the product is recycled to the second stage until substantially complete conversion to benzine is achieved unless Diesel oil is wanted in which case some middle oil is not recycled. Suitable catalysts for the first stage are compounds of metals of the 6th or 8th Group.  They may be applied to carriers such as lignite coke, silica gel, bleaching earth, kieselguhr or coke.  When using a finely-divided catalyst and/or when the crude oil contains more than 2 per cent. of asphalt, the first stage products are preferably led to a catch-pot from the bottom of which solids and unconverted asphalts may be withdrawn.  By using the same pressure in both stages, the product of the first stage may be allowed to flow directly into the second reaction zone. The carrier substances for the catalysts of the second stage may be a bleaching earth which has been pretreated with an acid, e.g. Hcl or HF or a synthetic silicate preferably prepared at a pH below 7, e.g. aluminium or magnesium silicate or an alumina which has been treated with acid.  In an example an aluminium salt solution and a precipitant are mixed at about 40 DEG C. and pH 7-10. The precipitated alumina is separated, washed, pressed to shape and heated at 300-600 DEG C.  Alternatively an alkali aluminate solution is precipitated with acid, and the precipitate is peptized, e.g. with nitric acid and shaped, dried and activated by heating.  The desired metallic compounds, e.g. molybdenum oxide or sulphide, tungsten trioxide or sulphide and if desired an oxide or sulphide of Cr, Zn, Fe, Ni or Co are then added.
