Title: Preparation of quarternary ammonium nitrites
IPC: C07C233/89
Filed: 1962-09-27
Abstract: N-aliphatic and N-dialiphatic quaternary ammonium nitrites, having 8 to 22 carbon atoms in the aliphatic radical, are prepared by making a slurry of sodium nitrite in a substantially non-aqueous solvent, preferably dimethyl formamide or a C1 to C4 alcohol, which is a solvent for the quaternary ammonium nitrite but not for sodium chloride, at a temperature of about 60 DEG  to 70 DEG  C., and then slowly adding a quaternary ammonium chloride to the slurry while the sodium chloride produced is precipitated, and recovering the resulting quaternary ammonium nitrite.  The slurry may be prepared by adding sodium nitrite to solvent heated to about 60 DEG  to 70 DEG C., or by mixing the nitrite and solvent cold and then heating to this temperature. The preferred alcohol is methanol.  After all the quaternary ammonium chloride has been added, the temperature may be raised to 70 DEG  to 80 DEG  C. and maintained at this level for two hours to complete the reaction.  The sodium nitrite is suitably used in a 20% molar excess compared with the stoichiometric amount required, and the quaternary ammonium chloride added as a solution in a suitable solvent (e.g. iso-propanol) which has been pre-heated to 60 DEG  to 70 DEG  C.  The quaternary ammonium chlorides may be derived from amines obtained from fatty acids of coco, soya, or tallow origin. Examples are given for preparation of quaternary ammonium nitrites, using the following corresponding chlorides: (1) Di-coco-dimethyl ammonium chloride; (2) mono-coco trimethyl ammonium chloride; and (3) di-stearyl-dimethyl ammonium chloride. The process is said to provide nitrites having a very low chloride content.

Abstract: 1,028,659. Printing and embossing apparatus. MODERN ENGRAVING & MACHINE CO. Sept.10, 1964, No. 37155/64. Heading B6C. In a machine for successively effecting multicolour printing and embossing on a travelling web 10 to thus produce a multiplicity of embossed coloured labels, the printing cylinders 12, 14, 16 are imaged such that any stretch transversely of the web arising in the bit of the embossing rollers 20, 22 is taken into account to ensure substantial registration of the printed and embossed designs. In order to effect such imaging for any particular web material travelling through a particular pair of embossing rollers with a particular roller bit pressure, the stretch of the embossing rollers is measured by passing therethrough a sheet of the web material thus providing an embossed sample 36. This is then photographed, the resulting print 40 being compared with a photograph 38 of the identical portion of the embossing design on the rollers 20, 22. Any displacement of the design on the sample 36 can thus be measured by overlaying the photographs 40 and 38, these measurements being subsequently used in the photo-engraving technique employed to image the cylinders 12, 14 and 16.

[Also in Division F1] A valve comprises a body 61, Fig. 1, having a vertical bore 96, a spool 94 slidable in the bore, the body having an annular recess 115 surrounding a portion of the spool and having a shoulder 113 at its upper end, a ring 99 located on the spool and projecting into the recess, the ring being engageable with the shoulder to arrest upward movement of the spool and a part of the shoulder defining an upper valve seat for the ring, a port 128 in the body commnicating constantly with the recess, a second port 72 communicating with a source of fluid under pressure, a passageway 96 between the spool and body extending between the second port and the valve seat, the ring being adapted upon engagement with the seat to cut-off engagement between the recess and the passageway and the spool having means 133 adjacent the upper end of the passageway to balance the fluid pressure on the ring when the latter is seated. A series of notches 76 enable the body to be screwed into firm engagement with synthetic rubber washers 73, 74 and 75 in a frame 16 while a convex cover 79 fits over a coil 78 surrounding an armature 84 secured to the spool to co-operate with an anvil 77 which may be covered with a thin washer 136 of synthetic resin. When the coil is energized, the spool 94 is displaced downwardly against a spring 93 to separate the ring 99 from the shoulder 113, allowing fluid to flow from the port 72 to the port 128, and to cause a second ring 101 to engage a shoulder 116, disconnecting the port 128 from an exhaust line 51. A sleeve 132 may be provided to serve as a positive stop on upward movement of the spool and to prevent the 0-rings 99, 101, which are of synthetic oil-resistant rubber, from being forced out of their grooves 105, 107 by fluid-pressure. By adjusting the length of the sleeve, it is possible to control the maximum deformation of the ring 99 and hence the area of the sealing surface between the ring and its seat. A modified sleeve to retain only the upper ring may be used. Fig. 7 shows a three-way valve in which a port 159 is provided in place of a fluted surface at the lower end of the spool and a port 124. To enable any port to be used as supply port, a second pressure-balancing means 152 is provided. The shoulders against which the rings seat may be conical and the rings may have a triangular cross-section. The valve may be used to control an engine braking system in which a lubricating oil pump 27, Fig. 1, provided with a pressure-regulating valve 28 draws oil from the engine crankcase 26 and supplies it to the port 72. When the coil 78 is energized by operation of a switch 89 coupled to the brake pedal or by a handoperated switch a valve 24 is lifted to the position shown in Fig. 7, to allow pressure fluid to flow through a line 44 to provide a connection, as described in Specification 912,138 between the injector rocker arm 19 and a slave piston 23 located above the enginedischarge valve 36.
