The intermediate isothiouronium derivative of benzo[b]thiophene is generally prepared by methylation of the thiourea derivative which in turn is formed from the amino derivative optionally via an N<SP>1</SP>-benzoyl urea derivative. The amino-benzo[b]thiophene derivatives may be formed by reduction of the nitro compound. A chlorine atom in the final product may be introduced into the intermediate nitro compound by diazotization followed by cuprous chloride treatment of the corresponding amino-nitro benzo[b]thiophene derivative, which in turn is formed by protection of the amino group by acetylation followed by nitration and removal of the protective group. 3-Chloro-5-amino benzo[b]thiophene may be prepared from 2-chloro benzonitrile by nitration of the latter to form 2-chloro-5-nitro-benzonitrile followed by reaction with methyl thioglycolate in the presence of potassium t-butoxide to form methyl 3-amino-5-nitrobenzo[b]thiophene-2-carboxylate which is diazotized and treated with cuprous chloride to form methyl 3-chloro-5-nitrobenzo[b]thiophene-2-carboxylate which is converted to its sodium saltand decarboxylated to yield 3-chloro-5-nitrobenzo[b]thiophene which is reduced to the required product. Pharmaceutical compositions of the 2-imidazolin-2-ylamino-halo-substituted benzo[b]thiophenes or the salts thereof alone or with the usual excipients show anti-hypertension activity when administered orally or parenterally.

Title: Improvements in or relating to electric signalling apparatus for use in conjunction with an automatic telephone system
IPC: H04M11/04
Filed: 1935-12-13
Abstract: 467,204. Fire, police, and like alarm systems; gramophones SHIPTON, E. Dec. 13, 1935, No. 34676. [Classes 40 (i) and 40 (ii)] [Also in Group XXXIX] In a system in which, on the occurrence of a fire or burglary or a change in the working condition of a machine, a call is automatically set up over the automatic-exchange telephone network to a fire &c. station and is followed by a phonographic or code signal identifying the calling station, the impulse transmitter generates a continuous stream of impulses of which certain are shortcircuited to constitute the required digits under control of a toothed disc 32. When an alarm &c. magnet 9, Fig. 5, is operated, a catch 5 releases the gear-train driven by motor 2 and a continuous stream of impulses is produced at contacts 42 by insulating cam 41 but these are short-circuited at contacts 47 except when member 46 is engaged by teeth on disc 32. The disc 32 is coupled to the gear-train after a short delay through a ratchet 29, the pawl of which is permitted to move into engagement when a lever 34 is deflected by a pin 36 striking an extension 37. Separate governors are provided for the motor and for the impulse cam. When the number has been sent, the pick-up 19, the pillar 21 of which is pivoted on a second pillar 22, is lowered on to the turntable 4 by engagement of cam 18 with an arm 24 to transmit the identifying signal, after which the pick-up is lifted off the turntable and returns to normal under the action of a spring 25. The motor is stopped by the re-engagement of catch 5 with pin 6, the catch being freed from the retaining catch 11 by oscillation of lever 52 effected through lever 50 by a pin on the geartrain. Off-normal contacts 58 are controlled by a plunger 57 engaging a notch in a disc 53 to short-circuit the calling bell and the pick-up during impulsing. The apparatus may be arranged to repeat the impulse transmission automatically, to make calls to two different destinations alternatively, e.g. the fire station or the police station, or to make calls to two different destinations consecutively, e.g. the fire station and the subscriber's private address. The motor may be an A.C. 50-cycle synchronous motor geared down at a ratio of 10 to 1 to give accurate impulsing speed. The apparatus may be combined with means for producing a record at the called station as described in Specification 461,319.

Title: Improvements relating to direct voltage transistor trigger circuits

IPC: G08B23/00
Filed: 1963-09-03
Abstract: 1,035,478. Transistor switching circuits- ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Sept. 2, 1964 [Sept. 3, 1963], No. 34828/63. Heading H3T. A circuit for monitoring a D.C. signal comprises a first transistor to which the D.C. signal is applied together with a square wave so that the transistor is conductive when the combined signal on its base is above a predetermined level and non-conductive when the combined signal is below another predetermined level, and two other transistors forming, with the first transistor, a bi-stable arrangement to accelerate switching of the first transistor between its two states. In Fig. 1 the signal to be monitored is applied between it1 and it2 to the base of Tr1, and the square wave is applied via Tr4 and a limit-setting resistor R5. Initially Tr1 is non-conducting and Tr2 and Tr3 are conducting, but if the combined signal becomes sufficiently positive it causes Trl to conduct and cut off the other two by bi-stable action across the common emitter resistor R1. If the combined signal then becomes sufficiently negative Tr1 will be cut off and the other two will conduct. The voltage levels at which switching occurs are set by R5 and R10. If the input D.C. is too high or too low, so that the combined signal never comes between these two levels, no output will be obtained at ot; the same will occur if there is a failure in the trigger circuit or the supply thereto. The A.C. signal at ot can be detected by passing it to an amplifier, transformer and rectifier bridge to which a relay is connected (Fig. 3, not shown). The voltage at it3 can be sinusoidal if it is squared before reaching the base of Tr1.

Filed: 1958-10-31
Abstract: 844,293. Sawing. INNOCENTI SOC. GEN PER L'INDUSTRIA METALLURGICA E MECCANICA. Oct. 31, 1958 [Nov. 5, 1957], No. 35062/58. Class 145. Tube issuing from a rolling or drawing mill is cut by a circular saw 9 carried by an axiallydisplaceable shaft 8 on a frame 6 which is rotated in bearings 4 about an axis parallel to the tube axis, the tube being supported in a carriage 23 which is lifted and then moved at the same speed as the tube when the rotation of the frame 7 brings the saw to the bottom of its circular orbit. By varying the speed of rotation of the frame with respect to the constant speed of the tube, varying lengths can be cut and the speed variation may be made by a mechanical transmission 21 on the driving motor 20 or by using a variable speed motor or by electronic equipment. The motor 20 also drives a face cam which through a roller 33 and link 36 drives the carriage 23 and a face cam 12 is engaged by a roller 13 and link 16 to displace the shaft 8 so that both the saw and carriage are moved in synchronism with the tube. Fluid pressure jacks 15 and 35 urge the rollers 17 and 33 against their cams. The carriage 23 is normally lowered so that the tube is clear of the saw orbit but is raised by a fluid pressure jack 28 and, by raising the carriage at each or every second or third rotation of the frame 6, lengths which are multiples of each other can be cut. The bearings 4 for the frame are carried in a member 3 which is pivoted at 2 and to reduce the impact speed as the saw contacts the work the member 3 is given a slight movement in the opposite direction to the rotation of the frame 6 by a fluid pressure jack 38. The saw may be driven by the motor 20 or by a motor on the frame 6 or by a motor 10 on a fixed support 44.

Abstract: 1461746 Welding by fusion; milling; joining tubing end-to-end ALUMINUM CO OF AMERICA 26 Aug 1975 [16 Sept 1974] 35231/75 Headings B3R B3A and B3K In welding together tube sections end-to-end, to provide a continuous length of tube for a drawing process, the tube section ends are both cut at a same angle of less than 90 degrees to their axes and are assembled in mating coaxial abutting relationship to provide a scarf joint interface, welding at said interface being effected by rotation of the tube section assembly beneath a welding head moved longitudinally of said assembly. The cuts may be simple, as in Fig. 1, e.g. at 30 degrees to the tube axis, or may comprise steeper additional portions 77, 80 as in Fig. 2, e.g. at 60 degrees to the tube axis. Each tube section is held by rotary clamps 20, 22, the clamp 20 being rotated by a motor 55 via a reducing gear 56, a pinion 54, and a gear wheel 36 having a hinged section 39 for tube section access. The clamps are mounted on supports 27 movable relatively along, and together, by way of a supporting platform 82, transversely of, the axis of the clamps. Before cutting, the tube section ends may be annealed; in the case of aluminium alloy tube, each 20 foot long end may be fully annealed and a 5 foot long transition length partially annealed. The end cuts may be cut by a carbide tipped rotary saw and may be finished by milling. As shown in Figs. 3, 7, a milling tool for effecting the Fig. 2 cuts comprises a rotary milling head 66 which has concentric arrays of form cutters 70, 72 and is tiltable about a transverse axis to effect the cuts and raisable and transversely movable to effect milling of the two tube section ends. The latter may then be straightened, as by the clamps. After the cutting and finishing, the tube ends are abutted and transversely rearwardly moved to a position beneath a longitudinally movable welding head provided with an electrode 60 and a filler wire feeder 58. The latter is angularly adjustable about a horizontal axis and, in order to present filler wire at a constant angle with respect to the joint interface is rotatable about a vertical axis by a reversible motor. During welding, the tubes may be rotated 360 degrees with overlap, in one direction, with or without a reverse rotation of 180 degrees before welding. Twist during rotation, with respect to fixed supplies of tubing is absorbed by the tubing.
