Title: Improvements in or relating to electric cables
IPC: H01B9/02
Filed: 1939-03-24
Abstract: 526,895. Cables. LIVERPOOL ELECTRIC CABLE CO., Ltd. and FROST, J. T. March 24, 1939, No. 9311. [Class 36] A cable includes a rubber, or a rubber or other composition, having electricallyconducting properties and an insulated live conductor or conductors and a non-insulated earthing conductor in contact with the rubber, whereby current leakage from the live conductor due to insulation-breakdown will be conveyed to the earth conductor. Flexible trailing cables, armoured cables, and electrostatically-screened cables are specifically referred to. In Fig. 1, two conductors c, d, each with an insulating rubber covering e, are laid up with an earthing conductor f having a conducting rubber sheath g, in a tough rubber sheath a and associated filling or " cracore " b of conducting rubber, whereby leakage from either or both cores e, d will pass via the latter to the earth conductor f. The sheath a may alternatively be of conducting rubber. More than three cores may be incorporated, as in Fig. 5, in which insulated cores c, d, j, k, one of which may be utilized as a pilot core, are laid up with an earth core l in the filling band sheath h, both of conducting rubber. A copperbraid screen m and tough or conducting rubber sheath n are also provided. Alternatively, Fig. 6 (not shown), the earthed core may be replaced by an insulated pilot core and one of the conductors c &c. may have a conducting-rubber sheath and serve as earth core. This latter form may be further modified by arranging all five cores at the apices of a pentagon. Fig. 7 (not shown). Instead of collective screening, these power cores may be screened individually and laid direct, with a central earth core, in a conducting-rubber sheath, Fig. 8 (not shown) and an insulated pilot core may be added, Fig. 9 (not shown). A single-core conductor, Fig. 10 (not shown), or a conductor having cores c, d covered with insulation e, may be located in a conducting-rubber sheath h in which is an earth core u, Fig. 11. A suitable rubber composition is that described in Specification 526,894, [Group V].

Title: A method of fractionating microporous particles by flotation
IPC: B03B5/44
Filed: 1948-04-02
Abstract: Alumina-silica, metal oxides, activated carbon, and other catalysts are separated into fractions having higher and lower specific surfaces by introducing into the pores thereof an impregnating liquid of a density different from the true density of the particles, dispersing the impregnated particles in a flotation liquid immiscible with the impregnating liquid and separating the dispersed particles into fractions denser and less dense than the flotation liquid, e.g. by settling or centrifugally.  The flotation liquid may be ethylene dibromide alone or in solution in toluene or carbon tetrachloride; bromoform in carbon tetrachloride; acetylene tetrabromide in carbon tetrachloride or benzene; or aqueous salt solutions; and the impregnant may be water, methanol or ethanol or aqueous solutions thereof; glycols or aqueous solutions thereof, aqueous salt solutions, lower organic acids or salts thereof, diisobutyl ether, ethylene dibromide, or isoamyl alcohol.ALSO:A mixture of microporous particles is separated according to porosity by introducing into the pores thereof an impregnating liquid of a density different from the true density of the particles, dispersing the impregnated particles in a flotation liquid immiscible with the impregnating liquid and having a density intermediate between the densities of the impregnated particles, and separating the dispersed particles into fractions denser than and less dense than the flotation liquid.  The impregnating liquid may be introduced into the pores of the particles by maintaining them in an atmosphere of the vaporized liquid or by blowing with a stream of air containing vaporized impregnant.  The latter preferably wets the particles in preference to the flotation liquid.  Final separation may be effected by settling or centrifugally.  The process may be applied to the fractionation of powdered catalysts into portions having higher and lower specific surfaces, e.g. alumina-silica catalysts, metal oxide catalysts or activated carbon may be treated.  Impregnating liquids include water; methanol and ethanol and aqueous solutions thereof; glycols and aqueous solutions thereof; aqueous salt solutions; lower organic acids or salts thereof; diisobutyl ether; ethylene dibromide; isoamyl alcohol.  Flotation liquids include ethylene dibromide alone or in solution in toluene or carbon tetrachloride; solutions of bromoform in carbon tetrachloride; solutions of acetylene tetrabromide in carbon tetrachloride or benzene; aqueous salt solutions.
Patent GB-827350-A (GB)
Title: Radio-oxonation of olefins
IPC: B01J19/08
Filed: 1958-03-25
Abstract: Olefinic compounds are reacted with hydrogen and carbon monoxide in the presence of a salt, oxide or carbonyl of a catalytically active heavy metal in the presence of at least 0.001 kilowatt hours per hour of high energy ionising radiation per pound of olefin feed.  The "high energy ionizing radiation" is defined as radiation from terrestrial sources consisting of photons having a wavelength less than 50  , such as gamma and X-rays, rapidly moving charged or uncharged particles of an atomic or subatomic nature having an energy above 30 EV., such as alpha particles and beta rays, and neutrons. The radiation can be obtained from any convenient source such as charged particle accelerators, e.g. Van de Graaf generators; linear accelerators; betatrons; and nuclear reactors, e.g. atomic piles. Materials from nuclear reactors, e.g. spent fuel elements; and materials made radioactive by insertion in a nuclear reactor, e.g. cobalt 60, can also be used.  If the radiation is obtained from a nuclear reactor it is preferred to shield the reactor so that substantially only gamma radiation is received by the reactants. When using a radio isotope the oxo reactants may be flowed in, around or through the source.  For example, to obtain gamma irradiation rods of cobalt 60 suitably clad in a protective coating such as stainless steel or aluminium can be disposed in the reactor with the reactors flowing about.  In the examples a cobalt 60 pipe source of radiation is used.ALSO:Oxonated compounds are obtained by a process comprising reacting an olefinic compound with carbon monoxide and hydrogen in the presence of a salt, oxide or carbonyl of a catalytically-active heavy metal in the presence of at least 0.001 kilowatt hours per hour of high energy ionizing radiation per pound of olefinic feed.  The "heavy metal" referred to is one having a specific gravity greater than 4, e.g. iron, cobalt, molybdenum and rhodium and suitable salts are those of stearic, palmitic, oleic, linoleic and naphthenic acids. The "high energy ionizing radiation" is defined as radiation from terrestial sources consisting of photons having a wavelength less than 50  , such as gamma and X-rays, rapidly moving charged or uncharged particles of an atomic or subatomic nature having an energy above 30 ev., such as alpha particles and beta rays, and neutrons. The radiation may be obtained from any convenient source such as charged particle accelerators, linear accelerators, betatrons and nuclear reactors.  Materials from nuclear reactors and materials made radioactive by insertion in a nuclear reactor, e.g. cobalt 60, may also be used.  In the examples: (a) propylene is oxonated in the presence of a carbonyl catalyst in the presence of a cobalt 60 pipe source of gamma radiation at 135 DEG  C. and 3100 p.s.i.g.; the product is hydrogenated in the presence of a copper chromite catalyst at 145 DEG  C. and under 3300 p.s.i. of hydrogen; and (b) heptene-1 is similarly oxonated.

Title: Improvements in machines for cutting continuously moving pastry strips or the like
IPC: A21C5/00
Filed: 1944-05-18
Abstract: 581,852. Cutting continuously moving strips of pastry &c. MONACO, A. May 18, 1944, No. 9573. [Class 87 (ii) ] A machine for cutting into lengths strips of pastry &c. which are moved continuously up to, through and beyond the machine by a conveyer, comprises one or more knives which are reciprocated longitudinally of the conveyer and are moved transversely of the conveyer in a closed path, the knives effecting the cutting operation while moving in one part of the path and returning clear of the strips of pastry &c. The disc cutters 36, Fig. 1, may be ganged on a shaft 34 whose ends are journalled in fittings on a pair of parallel chains 196 whereby the shaft is traversed horizontally above and across the conveyer B to sever the strips S of pastry thereon, the cutting shaft returning under the conveyerrun through positions in which the knives are washed and wiped. The sprockets for the cuttershaft carrying-chains are mounted in a carriage 32 which is reciprocated longitudinally of the conveyer by connecting rods 88 on a shaft 86 traversed by a pair of parallel chains 80, Fig. 2. Cutting takes place while the carriage 32 is moving at the same speed as the conveyer. Pressers 254 hold the strips lightly on to the conveyer during the cutting operation and are freed therefrom on the return movement of the carriage 32, the vertical movement of the pressers being effected by a cam bar 262 moved longitudinally relatively to the carriage by a fixed stop 270 at one end of the stroke of the carriage (to raise the pressers) and by a push rod actuated by the carriage traversing shaft 86 shortly after the commencement of the stroke of the carriage (to lower the pressers). The knives are resiliently mounted, being spring biassed so as normally to be concentric with the shaft, but allowing radial movement of the knives to take place. A spinner rail 210 engages a grooved pulley on the shaft 34 prior to the shaft 34 reaching the cutting position in order to impart an initial rotation to the knives. Spring pressed bars 204 also engage grooved pulleys on the cutter shaft 34 in order to guide and press the knives towards the conveyer during the cutting operation. The conveyer is guided to prevent lateral movement and is supported by rollers at the cutting position. Guide bars are fitted also to take the weight of the cutter-shaft carrying-chains in between their drive sprockets. The cutters pass between felts covering water-filled troughs 212, Fig. 3, while moving under the conveyer-run, in order to clean them, and are then wiped by a squeegee 226 which is carried upwardly in a guide 253 by an abutment on the cutter-shaft bearing, an angularly offset part 238 of the guide 253 carrying the squeegee clear of the abutment and allowing the squeegee to fall by gravity against a stop 252 ready for the next passage of the cutter-shaft.

Title: Improvements in or relating to the remote control and supervision of circuit breakers or the like in electric supply networks
IPC: H02J13/00
Filed: 1939-03-27
Abstract: 526,970. Electric selective signalling systems; protective cut-out systems. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., and BURNS, G. A. March 27, 1939, No. 9575. [Class 40 (i)] [Also in Group XXXVII] A tripped circuit-breaker is automatically re-closed from a remote point by apparatus thereat set in operation due to tripping in order to transmit repeated closing signals thereto if the breaker continues to trip open. The number of closures may be counted and when, say, three have occurred, further operations are prevented and an alarm given. The apparatus described comprises an addition to a known remotely-controlled selective system for a number of breakers as described in Specification 369,570. The control circuits comprise a common start key MST, contacts CON automatically positioned in accordance with the condition of each breaker and individual key contacts SLT. These circuits are connected over rectifiers MRA in multiple to the home contact of SEQ1 and individually to contacts of SEQ2. When the start key is thrown, any want of correspondence between CON and the manual keys SLT steps SEQ from the known position after which it is self-stepped until the magnet is held over relay SS and the first circuit having SLT, CON in non-corresponding positions. Relay OOC differentiates between an opening and closing order and together with SS completes circuits for controlling the main equipment. When the breaker-change has been signalled back to change CON, the switch SEQ proceeds to the next circuit. When it is required automatically to re-close breakers which trip open, keys SLT for such breakers are moved to the " closed " position and other keys to the neutral position or keys for open breakers may be in the open position. Start key MST is left thrown so that when any breaker trips, the above-described sequences of operation is performed and repeated if a breaker trips again. The number of times a breaker trips may be counted and the operations stopped and an alarm given after say, three sequences. A record of the performance of the breaker may be taken over a finder switch which tests the contacts CON. When a number of sequence circuits are used in a large system, they are started in turn by a distributer controlling relays which close contacts CAS in shunt of MST.

Title: Improvements in last line indicators for typewriters
IPC: B41J29/48
Filed: 1920-04-07
Abstract: 141,355. White, D. G. Dec. 14, 1918, [Convention date]. Alarms.-A device for indicating when a sheet has been advanced through a pre-determined number of line-spaces is driven by the platenroller and is automatically uncoupled and restored to the normal position when the pre-determined line is reached. The device shown in Figs. 1 and 5 comprises a pinion 7 rotatable on a pin 17 secured to a yoke 9 which can be depressed to. cause the pinion to engage a pinion 8 on the shaft 4 of the platen roller 5. The yoke is formed with a depending part 10 having channelled sides 11 which engage guide-lugs 14, 15 on the platen carriage 2. The yoke is retained in either the raised or the depressed position by springs 31, 32, Fig. 5; the springs may be provided with eyelets for engaging a pin 35 on the part 10 of the yoke. The pinion 7 is provided with a pin 22 for operating the hammer 34 of a bell 30, the pin being normally held in contact with a projection 23 on the carriage by a spring 19. The pinion 7 is provided with an adjustable stop member 27 which is set by the aid of a scale 25 or by trial, and consists of a rotary blade provided with a projecting stop 29 which can enter the tooth spaces of the pinion and co-operates with the pinion 8 in the manner described below. In operation, the yoke is maintained in the raised position, shown in Fig. 5, until the first line on the sheet has been brought to the printing line. and the yoke is then depressed to bring the pinion 7 into mesh with the pinion 8. When the sheet has been advanced through the number of line-spaces determined by the setting of the stop 29, the pinion 8 engages the stop, and the yoke is lifted, the pinion 7 being thereby released from the pinion 8. The spring 19 then rotates the pinion 7, and the pin 22 passes over the tail 33 of the hammer 34, the hammer falling and striking the bell when released by the pin. The tail 33 is flexible and yields during the upwards movement of the pin.

Title: Rotary gas and liquid meter, pump or engine
IPC: G01F3/22
Filed: 1936-04-02
Abstract: 455,422. Rotary engines. RUMMEL, R., 9, Anastasius-Grungasse, Vienna. April 2, 1936, No. 9817. Convention date, April 3, 1935. Addition to 448,903. [Class 110 (ii)] [See also Group XXXIV] The engine, pump or meter comprises a rotary drum 18 connected by flexible diaphragms 21 to a rotary piston 10 which slides around an eccentric part 4 of the casing. The piston is supported by bearings 12, 13, and the drum by bearings 22, 23. In the case of a meter gas enters a port 8 and is led to the interior of the part 4, from d through e to the chambers f, and is discharged through similar ports i, k, to an outlet 9. The inner part of the piston bears on blocks 14, 15, which are pressed apart by springs 17, and have lips 16 which slide in the mouths of the ports e, i. Three coupling rods 39, which may be flexible, link together a sleeve 27, secured to the piston, and the drum 18 through its extension 25. By providing slots in the rods 39, the driving is done by one rod in tension without placing the other two rods into compression. Coupling rods may be provided at each end of the piston. A spring ring 37 clamps the inner ends of a diaphragm in position on the piston, and a conical frame 18 secures the outer ends to the drum. The interior of the casing 3 is connected with the gas outlet side so as to equalize the pressures on each side of the diaphragm. A gear wheel 31 drives the meter recording mechanism 30 through a shaft 32. Fig. 9 shows a packing means 44 between the fixed part 5, and one of the sliding blocks 14. Further packing means of these parts, are described in the Specification. In the arrangement shown in Fig. 13, parts 11 are drawn towards each other by springs 61. These parts are formed of softer material than the outer surface of 4 upon which they rub, to prevent undue wear of the latter. Counter-weights may be connected to the parts 11 through bell-crank levers, to reduce the effect of centrifugal force on the part 4, at high speed, and force the ends of 11 into contact with the part 4. The bearing race rings for the piston and the drum may be formed of sheet metal as shown in Figs. 24, 25,
