Title: Improvements in means for locking haulage clips in operative position
IPC: B61B12/12
Filed: 1947-04-22
Abstract: 627,437. Rope grips. WILLIAMS, S. E. April 22, 1947, No. 10669. [Class 78 (ii)] A haulage clip is of the kind comprising two coacting side cheeks 1 provided with jaws 5, the cheeks being loosely mounted upon and connected by a lower bolt 2 and by a parallel upper pivot pin 3 whereby they are capable of rocking sideways by action of an interposed rocker head 9 formed with an operating hand lever 8 pivoting on the pin, the head moving between the cheeks so that the jaws are closed laterally upon the rope or cable. It is characterised in that operating hand lever 8 is formed also with a crank or drop arm 10 which is connected to the load whereby the grip of the clip is locked by the rocker head both when the force of the load is tensionally imposed and also when compressively imposed due to overrunning. Fig. 1. Side cheeks 1, each formed with a jaw 5, are connected together by bolt 2 and by pivot pin 3, and are each formed with an inner cam face 6 and a stop 7. Working between these cam faces are cam faces formed on arm 9 of the operating handle 8, the other arm 10 of which is pivotally connected at 12 to curved link 11 which is pivotally connected at 14 to bar 13 attached to the load. Handle 8 pivots on pin 3. Operation. Handle 8 is swung clockwise so that arm 9 moves towards stop 7 and by cam action forces the jaws 5 to grip .the rope therebetween. This grip on the rope is increased by the pull of the load on bar 13 which gives a clockwise rotation to the cam-face on arm 9. Thus when the load moves along an upward or horizontal path, bar 13 assumes the position shown and, by means of stop 15, rotates arm 9 and increases the grip. Likewise when the load moves along a downward path bar 13 rotates arm 9 and increases the grip, the load overrunning the rope and causing link 11 to rotate clockwise till it abuts against arm 9 and thus gives it a clockwise rotation. Fig. 5. Alternatively, arm 10 may be pivoted to link 11a which is pivoted to hooked loadcoupling bar 13a. In place of the hook there may be an eyeshaped coupling.

Title: Electronic monitoring apparatus
IPC: C12M1/20
Filed: 1975-03-14
Abstract: 1536306 Analogue calculating BRITISH STEEL CORP 12 March 1976 [14 March 1975] 10767/75 Heading G4G The condition of a piece of machinery, e.g. a bearing, is ascertained by calculation of the kurtosis coefficient of a stationary stochastic signal emitted by the device. This coefficient normally approximates to 3, but exceeds this value, e.g. in the initial stages of the failure of a bearing. It is defined as the normalizer fourth moment of the stochastic function and can be expressed by the integral normalized with respect to the root mean square of the function (x is the mean value of x). In the analogue computer shown, the signal x is multiplied in a multiplier 3 by a factor A = #K/##<SP>2</SP> (this factor is proportional to the root mean square of x). The signal Ax is squared in the circuit 3 and fed to the integrator 4 where the integral is equated to K. The signal is further squared and integrated in circuits 5 and 7 to produce an output representing the kurtosis coefficient. A comparator 8 may be used to determine when the normalizer value of x exceeds a certain value, and a device 10 may be used to indicate the proportion of time during which this value is exceeded. In a modification (Fig. 2, not shown), the circuit 4 is replaced by an A/D converter and a digital computer for the gain factor of a multiplier 2. In addition the computer controls the selection of frequency bands within a bank of filters connected to the output of the multiplier.

Title: Improvements in gas blast electric circuit breakers
Inventor: JANSSON GUSTAV EMANUEL
IPC: H01H33/14
Filed: 1951-05-08
Abstract: 706,786. Gas-blast switches. ALLIS-CHALMERS MANUFACTURING CO. May 8, 1951, No. 10773/51. Class 38(5) In a gas-blast switch, the opening of one or more pairs of co-operating. contacts is so related to the opening of the blast-valve that the contacts open when a predetermined pressure value of the blast reaches them, this being effected by operating the contacts through the medium of a rotatable column by a fluid motor actuated by the blast gas. In Figs. 2 and 3, the gas-blastswitch has four seriesconnected pairs of co-operating contacts 4, 5 in a blast passage 3 formed by hollow insulators 53 and passages indicated at 57, 73, in interposed metal casings 52 and venting structures 201. The moving contacts 5 are guided in members 54 and are actuated by toggle linkage 59, 60, 63 contained in the two casings 52. The linkage is moved by shafts 10 coupled by crank mechanisms 9 to a rotatable insulating column 8. To open the switch a solenoid-operated trip valve 41, Fig. 2, is operated to permit the flow of gas from a tank 1 through pipes 43 to a pilot valve 44, which opens to admit gas to the operating cylinder 47 of the blast valve 3a. The valve 3a is opened and gas flows up the passage or column 3. Gas is also supplied via a pipe 11 to a cylinder 12 of the fluid motor 6, moving the piston 13 to the left to turn the column 8 and open the contacts. The delay in the opening of the contacts relative to the opening of the blast valve is determined by the size of the pipe 11 which may be provided with a needle valve (not shown). A slide valve 38 associated with the cylinder 12 vents the left-hand side of the cylinder to atmosphere. Movement of the piston 13 to the left opens a port 14 and gas is supplied from the cylinder 12 through a pipe 15 to a cylinder 19 and slide valve 20. The piston 18 in the cylinder 19 is moved to the left to open an isolating switch 17, the slide valve 20 venting the left hand side of the cylinder to atmosphere. The opening of the isolator is accompanied by the closing of contacts 33 to energize the coil of a contact-resetting valve 35. The valve 35 opens and gas flows to the slide valve 38 and cylinder 12, causing the piston 13 to move to the right to reclose the contacts 4, 5, the slide valve venting the right-hand side of the cylinder to atmosphere. The controlled circuit remains open at the contacts 22, 23 of the isolator 17. To reclose the circuit, a solenoid-operated valve 49 is energized to supply gas to the left-hand sides of the cylinder 19 and slide valve 20. The piston 18 is them moved to the right and recloses the isolator 17.

Title: Improved process for producing sulphur
IPC: C01B17/04
Filed: 1930-04-05
Abstract: <PICT:0350124/III/1> In the formation of sulphur from gases containing sulphur dioxide, such as furnace gases or those from the roasting of sulphur ores, by passing these gases, preheated at 300-800 DEG  C., into contact with heated coke &c. at a temperature of at least 1000 DEG  C. with the formation of carbon monoxide and dioxide, the monoxide is converted to dioxide by the addition to the outgoing gases of secondary gases containing free oxygen which may be preheat d, the amount of oxygen being insufficient to combine with all the monoxide present; the heat thus generated is returned directly or indirectly to the reaction zone.  Should the original gases contain free oxygen, these may be employed as the secondary gases, care being taken that the monoxide remains in slight excess. In the apparatus shown, a shaft furnace A, in which coke is maintained at the level L, is provided with annular flues l, m. The sulphur dioxide containing gases enter at D and pass into the flues l, m by ports x, y, secondary air being supplied by pipes o, p, the heat generated serving to maintain the temperature of the coke bed. The final gases leave by a flue E and may serve for preheating purposes.  An example is given and Specification 328,643, [Class 55 (i), Coking &c.], is referred to.

Title: Improvements in or relating to the manufacture of calcium, barium and strontium
IPC: C22B26/20
Filed: 1948-04-20
Abstract: 644,941. Distilling calcium, barium or strontium. SOC. ELECTRO-METALLURGIQUE DU PLANET. April 20, 1948, No. 10921. Convention date, April 25, 1947. [Class 82(i)] A method for the preparation of barium, calcium or strontium includes the steps of mixing the oxide of the metal and a reducing agent in a pulverulent state, compressing the mixture into blocks, drying and freeing the blocks of occluded gases, arranging them in a single layer opposite a source of heat in a furnace which is exhausted, e.g. to 10-200 thousandths of a millimeter of mercury and at a temperature of, for example, 1150-1400‹C and condensing the metal vapours produced directly to the solid state in vacuum. Fig. 1 shows a furnace chamber 2 into which the blocks 5 are charged through a door 6 on to hearth 4. A heating resistance 3 passes through sealing insulators 3a. Metal vapour passes along passage 7 and through a right-angle bend to a passage 9, dust particles being carried by their own inertia to a heated dust trap 10. Passage 9, Fig, 2, leads to a condenser chamber 11, the vapours being condensed in condenser 12 which is heated to the required temperature by resistance 12a and maintained under vacuum by connection to a vacuum pump via passage 18. A trap may be connected between the pump and condenser to condense any metal vapour which passes through the condenser. At the end of the reduction, condenser 12 is disconnected and withdrawn into an auxiliary chamber 16 which is isolated from the rest of the apparatus by gas-tight doors 15 and 17. The condenser may then be heated to liquefy the metal and allow the formation of an ingot which may be refined by distillation or sublimation. In a modification the reaction chamber is in the form of a vertical cylinder, the blocks being built in the form of a vertical cylindrical wall having the heating resistance on its axis. Specification 590,437 is referred to.
