Abstract: 539,893. Sulphonamido compounds. MERCK & CO., Inc. March 20, 1940, No. 5168. Convention date, March 23, 1939. [Class 2 (iii)] 2 - p - Aminobenzenesulphonamidopyridine, described in Specification 512,145, is converted into its water-soluble N-sodium methylenesulphinate bv treatment with sodium formaldehyde-sulphoxylate in water, glycerine or an aliphatic alcohol or glycol as solvent. The water-soluble disodium compound is obtained if the starting material is used in the form of its sodium compound ; treatment of the disodium compound with mineral acid gives rise to the monosodium compound, from which the disodium compound can be regenerated with caustic soda. The free methylenesulphinic acid may be prepared from the disodium compound by treatment with acetic acid. The products are useful therapeutically. An example is given of the preparation of the monosodium compound, i.e. the N-sodium methylenesulphinate.

Abstract: <PICT:0661223/III/1> <PICT:0661223/III/2> In effecting vapour-phase endothermic reactions, e.g., cracking of hydrocarbons, by passing the reactants upwardly through a reaction zone to contact a downwardly moving compact bed of granular heat - exchange material, a portion of the heat-exchange material is introduced to the top of the zone at a temperature substantially below the reaction temperature thereby effecting a cooling of the reaction products and the remainder of the material is introduced to an intermediate portion of the zone at a temperature not lower than the reaction temperature.  As shown (Fig. 1) granular solid is circulated in a closed cycle through reactor 10, elevator 11 and chute 8, a portion then being passed through heater 12 to enter the bulk supply zone positioned above plate 22 in the reactor and the remainder through cooler 13 to enter the bulk supply zone positioned above plate 21.  Cooled and heated solid is transferred from the bulk supply zones through pipes 23, 24 respectively, the heated solid entering the reaction zone at a point intermediate the reactant entry 25 and the lower ends of pipes 23. Reaction products leave at 33.  Heating and cooling of the solid in 12 and 13 is effected by burning fuel and air respectively.  Purging steam is admitted at the various points 20, 201 and 29.  In a modification (Fig. 2) the solid is cooled as it leaves the reactor by water admitted at 46 and heating of a portion of the solid is effected in a zone positioned below the upper plate 36.  The various hot and cold solid supply pipes may be provided with a heat-insulating sleeve 48 (Fig. 3) and with a flared and perforated lower end 49.

Title: Pipe cladding

Filed: 1973-02-05
Abstract: 1449462 Insulating pipes FOSECO INTERNATIONAL Ltd 4 Feb 1974 [5 Feb 1973] 5632/73 Heading F2P [Also in Division F4] A method of cladding a water cooled pipe 1, e.g. to form a skid rail for use in a furnace, includes the steps of surrounding part of the pipe 1 with a channel shaped member 2 of generally inverted U-shaped cross-section, surrounding the remainder with a closure plate 3 spanning the open end of the "U" and which cannot be removed radially of the pipe 1 without breakage of the plate 3 or channel member 2, and at least partially filling the interspace between the pipe 1 and the channel member 2 and plate 3 with heat insulating refactory material 5, e.g. felted or woven blankets of inorganic fibres such as glass fibre, rock wool, mineral wool, ceramic fibres or aluminosilicate fibres. The channel member 2 and plate 3 are both preferably made of refactory cements or cement bonded refactory materials. In a first embodiment (Fig. 1) the plate 3 is locked in position by a cement "key" 4 formed between a tapered surface 8 of the member 2 and a groove 6 in the edge of the plate 3. The plate is held in position while the cement 4 sets by rods 7 engaging the grooves 6. In a modification (not shown) the channel member 2 and plate 3 surround two pipes. In a second embodiment (Fig. 3) the plate 12 is locked in the channel member 11 by interengaging inclined faces 13, 14, the plate 12 being slid longitudinally into the member 11 and then being secured by cement fillets 15.

Title: Improvements relating to control systems for electric motors
IPC: B65H23/18
Filed: 1955-02-25
Abstract: 764,174. Automatic speed control systems.  ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. Feb. 25, 1955 [March 1, 1954], No. 5649/55. Class 38 (4). [Also in Group XXXVII] In a textile machine, material is treated by sizing rollers 2 in travelling to a receiving beam 4, a roller 3 being driven by the material as it wound on to the beam. The rollers 2 and beam 4 are respectively driven by motors 6 and 7, a control generator 8 being driven by the roller 3. A constant speed motor 5a drives a main generator 5b supplying the motors 6, 7, as well as additional generators 5c, 5d, and an exciter 5e, an adjusting rheostat 9 being connected in the field circuit of the main generator. The field excitation of the motor 7 is derived from the exciter 5e in opposition to the machine 5c which has a self-excited field winding 5c1 acting cumulatively with a field winding 5c2 having constant excitation. These field windings are opposed by a winding 5c3 carrying the armature current of the control generator 8, the voltage of which is opposed to that of the main generator in the excitation circuit of the field winding 5c3. The generator 5d is connected in the circuit of the winding 5c3 to compensate for the internal voltage drop in the generator 8. As the diameter of the material on the beam 4 increases, the speed of the generator 8 will also tend to increase so that the excitation of field winding 5a3 counteracts that of the windings 5c1, 5c2, and the voltage output of the generator 5c is reduced. This leads to higher field excitation for the motor 7 and decreased speed until the excitation of the machine 5c reaches a new state of equilibrium with the windings 5c2, 5c3, cancelling each other and the machine acting as a self-excited generator. The tension of the material between the rollers 2 and 3 is independently adjusted by means of rheostate 14 in the field circuit of the generator 8. An adjustment of rheostat 11 in series with field winding 5c2 alters the tension between rollers 3 and beam 4. Rheostats 11, 12 are ganged because any adjustment of rheostat 11 alters the voltage and current output of generator 8 and calls for a new value of compensation from the generator 5d.

Title: Improvements in devices for guiding threads or filaments
IPC: D01D10/04
Filed: 1946-02-23
Abstract: In a continuous process for the manufacture of artificial threads in which the thread advances in helical loops along a pair of mutually inclined rollers 6, 7 positively driven at the same angular speed whilst undergoing coagulation and other <PICT:0608435/IV(a)/1> stages in manufacture, the threads are given an initial stretch before coagulation is complete by providing a step 5 at the forward end of roller 6 which first receives the thread from the coagulation bath 2, the step being of smaller diameter than the second roller 7.  The amount of stretch applied is substantially equal to the natural extension of the thread when allowed to coagulate under tension. Instead of a single step 5, a plurality of steps may be provided, or the forward end of the first roller may be conical.

Patent GB-1583633-A (GB)
Title: Distributed control for switching system
IPC: H04Q11/04
Filed: 1978-02-14
Abstract: The switching network (102), which contains switching matrices (104 - 110; 120, 122) arranged in several stages, is connected via common speech paths (204) with a group of interface devices (128), in which analog to digital and digital to analog conversion of the signals from and to the subscriber is carried out. Digital subscriber lines (130, 136, 138) are connected to the switching network 102 via a digital subscriber's apparatus (140). The translators which are present in the database (142) are used as usual to translate the digits keyed by the subscriber; however, they are also used for distributed control of the system, since they work with a single data connection path, which is only a speech path (204), between the interface device and the switching network. Since the interface units (128) control the establishment of connection paths to the switching network, the central processor which was previously required is omitted. This makes it possible to keep down the cost of testing when the program changes. <IMAGE>
