Patent GB-780271-A (GB)
Title: Process of making isocinchomeronic acid and decarboxylation of same to niacin
IPC: C07D213/803
Filed: 1954-11-09
Abstract: Nicotinic acid is manufactured by oxidizing a 2 : 5-dialkylpyridine to isocinchomeronic acid by means of nitric acid under superatmospheric pressures at temperatures below 180 DEG  C. (e.g. 155-180 DEG  C.), recovering the isocinchomeronic acid substantially free from nitric acid, mixing it with an inert liquid vehicle consisting of water, commercial heat transfer oil, sulphuric acid or cyclohexanone, and heating the mixture above 180 DEG  C. to effect decarboxylation.  The nicotinic acid may conveniently be isolated, especially when sulphuric acid has been used in the decarboxylation step, by esterifying it by heating the reaction products with a lower (1-6 C) alkanol (e.g. ethanol), cooling, neutralizing and extracting the ester with a solvent. Examples illustrate the various features of the invention, starting with 2-methyl-5-ethylpyridine.  Specification 650,984 is referred to.

A crimping tool comprises a bored die holder 10 rigidly mounted in a carrier member 20 having a number of radially disposed crimping dies 38 mounted therein and an associated operating member 58 provided with a handle member 116 and having a cammed die member actuating surface 56 mounted for rotative displacement relative to the die holder. A control locator member 68 is insertable into the bore 28 for positioning a workpiece and controlling the depth of crimp. Each die has a dependent crimping tooth 50 which passes through a recess in the locator 68, a shoulder 46 on the die engaging with a stop surface disposed on either side of each recess in the locator, to limit the convergence of the dies. The locator member is maintained in position in the bore 28 by a manually displaceable forked slide 96. To ensure the completion of a full operating cycle a notched rack 130 mounted on the operating member 58, is engageable by a pawl mounted on the carrier member 20. A trigger plate 154 is pivoted at 156 on the carrier member 20. A trigger slide 170 mounted on the operating member 58 carries a cam surface 180. A link 176 mounted on the member 170 so as to be radially disposed to the bore 28, has the end adapted to abut with the surface of the locator 68 by engagement of the end of the link in a recess in the locator. On completion of the full crimping stroke, the cam surface 180, engages a trigger pin 152 on the plate 154 and causes disengagement of the pawl from the rack. The rack is thrown back along its path of travel by a spring 160 mounted on the handle 120 and assists in separating the handles and resetting the pawl assembly.

Abstract: 1,186,506. Ion-exchange. H. TRAVERS. 18 July, 1967, No. 32971/67. Heading B1J. A valve assembly which allows flow of rain water through an ion-exchanger and flow of regenerant through in the opposite direction, together with means for bypassing the exchanger is described. During softening (Fig. 3) water enters valve by pipe 10 and follows the direction of the arrows into exchanger via pipe 18 and returns via pipes 20 to pipe 12 which is the soft-water lime. During regeneration (Fig. 4) the valve is moved by means of spindle 44 and flow is now by direction of arrows with discharge to waste at 32. During regeneration the water can pass directly from inlet 10 to outlet line 12 but a quantity only passes through bleed passage 90 by reason of the ball valve 86 and draws in brine by line 30. The hydraulic balancing of the valve is described in relation to Fig. 5 (not shown).

[Class 60.] In apparatus for grinding rotary eccentric knives such as sickle knives 5 used in cigarette rod cutting machines, a grinding-wheel 1 is eccentrically mounted on a rotatable support 4 whose axis when produced intersects the working face of the grinding wheel. The grinding wheel is mounted on a spindle 2 adjustably clamped to the support 4 and having its axis inclined to that of the support. The support is driven by gearing 6, 7, from the drive for the knife 5 and its angular speed is equal to or a multiple of that of the knife. The apparatus is mounted on a frame 10 pivoted at 11 and adjustable to move the grinder up to or away from the knife by a nut 12. In a modification, the grinding disc may be replaced by a grinding roller freely rotatable about an axle which is inclined to and adjustably mounted on a rotatable support. These devices may be used for sharpening knives whether or not the knives reciprocate axially during the cutting operation. In another modification, Fig. 3, a conical or convex grinding disc 15 is mounted on a spindle 16 carried on a crank arm 17 extending from a rotary spindle 18 so that as the spindle 18 rotates in timed relation with the knife, the grinder moves to and from the knife axis to grind the desired eccentric edge.

Abstract: 333,619. Mathys, A. W., (Monroe Calculating Machine Co.). May 17, 1929. Multiplying and dividing apparatus. - In a calculating-machine for the four rules, two series of actuators are provided each for actuating its own totalizing-counter, and a disconnectible coupling may be set to connect one series with the other or to disconnect them, the arrangement being such that the same or different amounts may be entered positively or negatively in the two counters. In a modification only the one item may be entered in the totalizers. In the first form, Figs. 1 and 2, two keyboards 18, 35, are provided, the keys of which rock bars 19 in the usual way. The bars 19 are provided with connecting plates 37 so arranged that the movements of the bars 19 of the keyboard 18 are transmitted to the corresponding bars of the keyboard 35, but settings of the keyboard 35 are not transmitted to the boss of the keyboard 18. The connecting plates are brought into action by a lever 39 having a positioning detent 40. The amounts set up may be entered in the first totalizer 13 by the operation of a handle or by an electric motor. The actuation of the second totalizer 33 is controlled by a lever 42, which, by means of reversing gearing interposed between the prime mover shaft and the actuating shafts, causes the item set to be entered in the second totalizer positively or negatively with respect to the entry in the totalizer 13. The lever 42. may also be set to disconnect the two series of actuators. When the machine is motor driven, addition and subtraction keys 120, 121, a division lever 318 and multiplier keys 261 are provided. Independent clear keys 12, 43, one for each keyboard, are adapted to rock locking bails 6 to release any depressed keys. Non-repeat keys are also provided which, when set, cause the release of all the looking bails 6 by the operation of an universal clearing bar 23 at the end of an operative cycle. In the modification, Fig. 7, one keyboard 18 only is employed, the totalizers 13, 33, being arranged one behind the other and the rockbars 45 being extended as shown. A hand-lever is provided for shifting a clutch to connect the motor drive which the actuating shafts 46, 47, for rotation in the same or opposite sense. Specifications 27231/12 and 216,174 are referred to.

Abstract: 409,433. Loud - speakers. BRZESKI, H., 7, Szopena, Warsaw. Nov. 25, 1932, No. 33455. [Class 40 (iv).] In a loud-speaker, the magnetic field due to the speech currents is limited to a small space round the moving coil so that energy losses due to hysteresis and eddy currents are reduced. In one embodiment, the pole-pieces have inserts 15, 16, Fig. 1, of material of high magnetic permeability, such as permalloy or ferrocart. The former 13 on which the moving coil is wound may be of similar material. In another embodiment, two moving coils, Fig. 3, wound in opposite directions may be utilised, each driving separate oppositely directed diaphragms. This arrangement is stated to overcome the effect of energizing the magnet system with badly smoothed alternating current. Preferably the moving coil is wound in superposed layers, the potential difference between corresponding turns of adjacent layers being constant. The windings may be tapped and the sections connected in series, parallel or in series-parallel to adapt them to the amplifier, Figs. 6, 7 (not shown). The leads 21, Fig. 1, from the moving coil are led to pins 20 contacting with springs 19 connected to terminals 18.
