Title: Improvements in or relating to overload protection devices for tie rods in rolling mills
IPC: B02C4/28
Filed: 1960-06-27
Abstract: 915,048. Machinery breaking-pieces. MOELLER & NEUMANN G.m.b.H. June 27, 1960 [June 25, 1959], No. 22392/60. Class 80 (4). [Also in Group XXII] In a tie-rod 1 for a roll-stand, a reduced diameter breaking part 6a adapted to break at predetermined overload tension is provided in a pin 6 which is releasably secured to one end of the tie-rod and transmits the tie-rod clamping tension. As shown, the tie-rod 1 is hollow for elongation by hydraulic pressure acting on a screwedin plug 2 through a core pin 3. The pin 6 is screwed into the plug 2 and has a head 6b bearing against a sleeve 5 which is guided on the cylindrical end 2a of the plug and is externally screwed for engagement with a nut 4. To prevent its rotation with the nut 4 the sleeve 5 has teeth 5a engaging corresponding teeth in the rod 1. The rod 1 acts on a member 7 through the plug 2, the pin 6, the head 6b, the sleeve 5 and the nut 4. Spanner flats 8, 9 are provided on the plug 2 and the head 6b, respectively, and notches are provided in a collar 6c of the pin for withdrawal of the latter after breaking. The withdrawal and renewal of the pin can be effected without disturbing the nut 4 and the sleeve 5. In Fig. 2 (not shown), in order that the member 7, which may be the cap of a capped roll housing or a top roll chock acting on an adjustable spacer, together with the nut 4 and the sleeve 5, may be lifted without disturbing the pin 6, a removale divided ring held together by a garter spring is provided between the sleeve 5 and the head 6b. The bore of the sleeve is greater than the diameter of the head 6b and smaller than the bore in the member 7. The sleeve teeth 5a engage teeth in an element prevented from rotating relatively to the member 7. In this embodiment the nut 4 and the sleeve 5 may be dispensed with, in which case the divided ring bears directly on the member 7. The tie-rod may alternatively be elongated mechanically. The pin 6 may alternatively be introduced directly into the tie-rod and may comprise the plug 2.
Patent GB-701106-A (GB)
Title: Improvements in and relating to the production of cyclo-olefines
Inventor: REED HUGH WILMA BOULTON
IPC: C07C2/46
Filed: 1950-09-12
Abstract: Cyclo-olefins containing at least 8 carbon atoms in the ring are produced by heating a conjugated diolefin with acetylene and a catalyst derived from nickel carbonyl by replacing at least one CO group with an organic compound of trivalent nitrogen or phosphorus. Thus, Ni(CO)4 may be reacted with cyclohexylamine, pyridine, phenylhydrazine, mesidine, triphenylamine or a tri-aryl or alkyl phosphine.  The preferred catalyst is bis (triphenyl phosphine) nickel dicarbonyl which separates out on adding 2 mols. of triphenyl phosphine to 1 of Ni(CO)4, and may be removed by filtering or decanting. Alternatively the catalyst may be prepared in situ. Suitable starting materials are butadiene or its alkyl derivatives, e.g. piperylene, isoprene, 2, 3-dimethyl-butadiene, and hexa-2, 4-diene.  Reaction is effected in the liquid phase using a solvent such as benzene, toluene or tetrahydrofuran to which the catalyst, a dehydrating agent such as calcium carbide, ethylene oxide or calcium oxide, equivalent to say 0.5-2 per cent. of the total weight, and a polymerization inhibitor, e.g. a phenol, hydroquinone, quinone or amine equal to .01-1 per cent. of the diolefin, may be added. Acetylene may then be passed in, preferably at up to 15 atmos., while an inert diluent such as nitrogen is preferably also introduced.  The catalyst is activated by heating to about 100 DEG  C. when a reaction occurs with rise of temperature.  The diolefin is added at 80-150, preferably 110-130 DEG  C., and the mixture then heated for say 2-10 hours.  Acetylene may be introduced periodically to maintain the pressure.  The products are removed by vacuum or steam distillation and fractionated. They are of use in preparing derivatives of cyclo-octane or octene, for example, and suberic acid.  In examples: (1) butadiene is reacted at about 130 DEG  C. and a pressure varying from 9-12 atmos. to yield cyclo-octa-1, 5-diene, 4-vinylcyclohexene, and butadiene trimer yielding cyclododecane on hydrogenation; (2) isoprene similarly yields methylcyclo-octatriene giving 1-methyl-cyclo-octene on hydrogenation.  The Provisional Specification comprises also the use as starting materials of substituted butadienes such as halogen or alkoxy butadienes or sorbic acid esters, and acetylenic compounds generally.ALSO:At least one CO group of nickel carbonyl is replaced with an organic compound of trivalent nitrogen or phosphorus such as cyclohexylamine, pyridine, phenylhydrazine, mesidine, triphenylamine, tri-aryl or alkyl phosphines.  The components may be brought together in the requisite amounts to form the double compounds.  Thus, bis (triphenyl phosphine) nickel dicarbonyl is made by adding 2 moles of triphenyl phosphine to 1 mole of Ni (CO)4, the solid complex separating being removed by filteration or or decantation.

Title: Improvements in and connected with electric circuit breakers
IPC: H01H83/10
Filed: 1954-07-31
Abstract: 763,228. Automatic circuit breakers; protective cut-out arrangements. CRABTREE & CO., Ltd., J. A., and COLEMAN, E. July 14, 1955 [July 31, 1954], No. 22419/54. Class 38(5) In a circuit-breaker, an earth leakage trip coil 13 and an overload coil 13a with a hydraulic time delay device are disposed parallel to each other on axes perpendicular to the rear face of an insulating base 1 which has. similarly shaped recesses 10 housing the coils. The coils act on independent armatures 22c each having a leg 23 and being pivoted at its centre of gravity to minimize undesired tripping due to vibration. The legs act on a common trip bar 24 to turn a catch on a shaft 24a to cause the collapse of a toggle 27, 28, the opening of spring-biased contact arms 29 (one shown) and the return of a spring- biased operating dolly 4 to its " off " position. In the double-pole single-phase circuit breaker shown, the earth leakage coil is normally connected between earth and frame terminals 20, 21 through contacts 19 and 35. When a test push button 18 is depressed the earth leakage coil is disconnected from the frame terminal by the opening of the contacts 19, 35. The end of the rod 17 on which the contact 19 is mounted then engages a flexible blade 36a to complete a circuit from the coil through rod 17, blade 36a, a further contact blade 36, a fixed contact 36b and a resistor (not shown) to the neutral terminal. As the movement of the rod 17 continues, the blade 36 is moved from the contact 36b to a contact 36c to disconnect the coil from the neutral terminal and to connect it to the line terminal 14 through the contact 36c and a second resistor 39. This arrangement ensures effective testing even if the line and neutral connections have been reversed. A lightning discharge gap 22 may be connected between the earth and frame terminals 20, 21. Specification 763,227 is referred to.

In the dewatering of aqueous pastes or slurries of hydrophobic solids such as carbon black or coal dust the slurry is mixed with a controlled amount of toluene, the solid separated from the water by filtration, draining or decanting and the toluene evaporated to complete the drying. Carbon paste is delivered through a line 10 to vat 11 where it is diluted with water and the suspension of carbon in water pumped by a pump 14 through a pipe 9 to separator 15 at the base of.which grit collects, excess water escaping via line 16. Grit can be cleared through valve 17. The carbon paste now runs via funnels 18 into the first of mixing vessels 19, 20, 21 assisted by water from valves 22, 23 and toluene from a tank 24, transferred by a pump 25 through line 27 to a header 26 passes via valves 5, 6 into vessels 19, 20 which have stirrers therein and which communicate with each other by automatic overflows 29 or valves 30. From the final mixer 21 the suspension runs to a granule separator 39 where the water drains off through a metal screen 32 to a tank 33 and a pump 34 recycles it through line 7 to valve 22. The drained carbon granules fall down an enclosed chute 41 to a steam-heated drier 42 and the dried granules are delivered by a rotary valve 44 to a sifter 45 from which the product is withdrawn at 45a. Toluene and water vapour leave drier 42 along a pipe 46 and enter a condenser 47 having an incondensibles line 51 to a receiver 36 and a condensate line 48 to a continuous separator 49 which delivers water to tank 33 and toluene to tank 24 through lines 52, 53 respectively.
