Patent GB-829015-A (GB)
Title: Improvements in or relating to tropane derivatives
Filed: 1956-08-31
Abstract: 3-Acyloxy-6 and/or 7-hydroxytropanes are prepared by heating 3-acyloxy-6 and/or 7-aryl-carbamyloxytropanes to decompose the aryl-carbamyloxy group(s).  dl-3a -acetoxy-6b -hydroxytropane and dl - 3a  - isovaleryloxy - 6b  - hydroxytropane and their salts, specifically the hydrochlorides, are claimed per se.  The heat decomposition is preferably effected under reduced pressure, e.g. at 200-240 DEG  C. at 0.5 to 4.0 mm.  The arylcarbamyloxy compounds may be prepared by reacting an arylisocyanate with a 6 and/or 7-hydroxytropane-3-one followed by reduction of the 3-keto group and acylation of the resulting hydroxyl group.  Catalytic hydrogenation yields an a -hydroxy group and reduction with complex metal hydrides a b -hydroxy group.  The racemic 3a -isovaleryloxy6b -hydroxytropane may be resolved to give (-)-valeroidine, e.g. with d-tartaric acid, l (+)-glutaminic acid or (+) - bromocamphor - sulphonic acid.  The 6-hydroxy group of the products may be reacted with a sulphonyl halide and the sulphonyl group subsequently eliminated to give D 6 : 7-derivatives.  The 6-hydroxy group may also be replaced by halogen, e.g. with a phosphorous halide, and hydrogen halide subsequently eliminated to give the D 6 : 7-compounds.

Title: Improvements in or relating to impulse senders of the finger disc type
IPC: H04M1/31
Filed: 1928-09-18
Abstract: 297,388. Telefonaktiebalaget L. M. Ericsson. Sept. 20, 1927, [Convention date]. Impulse transmitters for automatic exchange systems. In an instrument of the finger-dial type the contact springs 11 - - 13 are located between the circumference of the impulse wheel 9 and the dial shaft 2 and are actuated by a spring arm 16 which moves in a plane parallel to that of the impulse wheel. The arm 16 carries a pivoted pawl 18 having a sloped projecting end 19 which engages with sloping teeth on the impulse wheel, the pawl being held normally in the position shown in Fig. 4 by a spring 20. In the normal position of the impulse wheel the projection 19 rests on a reduced portion of the wheel so that off-normal contacts 12, 13 are held open. During the setting operation the pawl 18 oscillates in its own plane and the spring 16 only moves sufficiently to close contacts 12, 13. During the return movement, however, the oscillation of the pawl in the opposite direction is prevented by a stop 22 formed by a projection on the spring 16 so that the pawl and spring 16 are lifted to the top of each tooth and the spring 11, 12 are separated to send impulses. The return movement is controlled by a governor 27 geared to a toothed wheel which is connected to the shaft 2 by a oneway friction clutch consisting of a spiral spring.

Title: Improvements in carbon electrodes made from coke
IPC: C25C3/12
Filed: 1955-09-28
Abstract: A carbon electrode (prebaked and self-baking) having a minimum crushing strength of 4400 lb./sq. in., a minimum density of 1.45 and a maximum resistiviity of 3 x 10-3 ohm.-in. is produced by baking a mixture of coke particles and a carbonaceous binder, 20-50 per cent of the coke particles having a diameter of less than 75 microns and at least a portion of the coke, e.g. 1-50, and preferably 20-40 per cent, consisting of a calcined and ground "fluid" coke having a real density of 1.83-1.93, preferably 1.87-1.92.  The fluid coke preferably has a resistivity of 20-30 x 10-3 ohm.-in.  The "fluid" coke is produced in a cyclic process which comprises injecting hydrocarbon oil into a reaction vessel containing a fluidized bed of hot coke particles.  The process is generally operated with particles having a diameter of 100-1000 microns, the average diameter being 150-400 microns.  Not more than 5 per cent of the particles should have a diameter below 75 microns.  After cracking of the hydrocarbon the resulting coated coke particles are stripped with steam to remove residual oil in a separate vessel, raised to reaction temperature again by burning a portion of the coke with air in a still further vessel and recycled to the reaction vessel.  Hydrocarbon oils suitable are heavy or reduced crudes, vacuum bottoms, pitch, asphalt having an initial b.p. of 700 DEG F. or higher and an A.P.I. gravity of 0-20 DEG .  The fluid coke is calcined at a temperature of 2000-2800 DEG F. or higher in a fluid, moving, or fixed bed in an atmosphere of air, nitrogen, carbon dioxide or hydrogen.  The calcination is continued until the desired density is obtained. The time of calcination is generally 0.5-10 hrs.  A portion of the coke may consist of calcined "delayed" coke.  Preferably, the delayed coke is calcined to a real density of 2, and 80 per cent of the coke has a particle size of 1/2 in. -200 mesh. The binder may be an aromatic coal tar pitch having b.p. 70-120 DEG C.
