Title: Process for the production of a 2-pyrrolidinone derivative
Filed: 1962-02-27
Abstract: 1 - C1 - Pyrrolin - 2 - yl) - 2 - pyrrolidinone or its metaphosphate is employed as an activator in the base-catalysed polymerization of pyrrolidinone. The compounds are prepared by treating pyrrolidinone with P2O5.  A specified polymerization is effected by treating pyrrolidinone to which sodium pyrrolidinone has been added as basic catalyst with 1-(1-pyrrolin-2-yl)-2-pyrrolidinone.ALSO:The invention comprises 1-(1-pyrrolin-2-yl)-2-pyrrolidinone and a process for the production thereof by heating a mixture of 2-pyrrolidinone and a substantially non-acylating, at least potentially acidic dehydrating agent, to 50 DEG  to 250 DEG  C. to form an acid salt of 1-(1-pyrrolin-2-yl)-2-pyrrolidinone, mixing the reaction mixture with an excess of an aqueous base, and recovering the 1-(1-pyrrolin-2-yl)-2-pyrrolidinone.  It is preferred to employ the dehydrating agent, e.g. phosphorus pentoxide, in an amount 25% to 125% by weight of the 2-pyrrolidinone and to add the reaction mixture to a stoichiometric excess of a concentrated aqueous base, e.g. potassium carbonate.  The intermediate acid salt of 1(1 - pyrrolin - 2 - yl) - 2 - pyrrolidinone with the dehydrating agent may be isolated prior to addition of the aqueous base by recrystallisation under anhydrous conditions. The invention also comprises the metaphosphoric acid salt of 1(1-pyrrolin-2-yl)-2-pyrrolidinone which may be prepared in this manner. The compounds of the invention may be used as activators for the base catalysed polymerisation of pyrrolidinone.

Abstract: 1,012,353. Aircraft ejection equipment. J. MARTIN. Feb. 7, 1964 [Feb. 27, 1963], No. 7933/63. Heading B7G. [Also in Division A3] The occupant of an ejection seat is positioned correctly on initiation of ejection by a reel carrying a strap attached to the occupant or his harness, and adapted to tension the strap. As shown, there are two reels 4 integral with a hollow shaft 1 and carrying straps 5 constituting the occupant's shoulder straps. The straps are wound in by rotating the shaft 1 by a pinion 9 and rack 10, the rack having a piston 21 and lying in a cylinder 18 subjected to fluid pressure, e.g. from a cartridge. The straps are also maintaned in tension by a torsion spring 13 fixed at one end to a stationary spindle 12 and at the other end to the hollow shaft. The seat occupant is held against forward movement by a ratchet 24 fixed to the shaft 1 and held by a pawl 25 (Fig. 6) mounted on a shaft 26. Normally the pawl is held out of engagement by rotating the shaft 26, but an acceleration-sensitive over-centre spring toggle (Fig. 4, not shown) rotates the shaft so that the pawl engages the ratchet at a predetermined inertia load, e.g. at the commencement of ejection. The straps may be tightened by reciprocating a plunger 29 (Fig. 6) on which is mounted a pawl 32 which engages the ratchet 24 to rotate the shaft 1.

Abstract: 1443085 Wells &c HALLIBURTON CO 21 Feb 1974 [13 March 1973] 8027/74 Heading E1F A formation tester 1 insertable in a pipe string (not shown) and having a through-bore 111 comprises a housing 200, a mandrel 112 reciprocable in the housing, and a valve 5 opened and closed by reciprocation of the mandrel. The upper part 2 of the housing is connected to the upper part of the string and the lower part 151 of the mandrel is connected to the lower part of the string which includes a packer. The tester with the valve closed as shown is run into the well on the string, well fluids passing through holes 28 (Fig. 1c) and acting on surfaces 68, 69 of an upper mandrel 56 detachably fixed to the housing by spring fingers 67. Well fluids also pass through holes 141 (Fig. 1e) to act on one side of a piston 137, the other side of which is acted upon by a charge of fluid in a chamber 136. At the test depth the packer is set and the valve is opened by setting down on the string, compressing a spring 155 and moving the mandrel 112 further into the housing, lugs 148 carried by the mandrel 112 moving from positions A to B in a cam slot in a sleeve 101 (Fig. 9) forming part of the housing. The rate of movement of the mandrel is governed by the rate of discharge of a fluid charge from a chamber 158 through an adjustable annulus. As the mandrel 112 moves into the housing a groove 105 (Fig. 1c) moves opposite to the ends 76 of the spring fingers to free the upper mandrel 56 from the housing to permit the mandrel 56 to be moved by the mandrel 112. When the mandrels have moved sufficiently for the ports 63 in the mandrel 56 to pass a seal 37, the hydraulic pressure in the tester below the valve is reduced to reduce pressure on the bottom of a collar 7 and hence on the valve. As the mandrels move further the mandrel 56 engages pins 14 (Fig. 1b) to raise a sleeve 11 which carries with it members 6 having pins 61. As the pins move they rotate the valve to the open position. When the valve is partially open the outflow from the chamber 158 is no longer restricted and the final opening of the valve is rapid so that an indication is given at the surface. The valve remains open all the while there is a weight on the string. When the tester is to be closed the. string is picked up and then released, the lug moving to the position C and then to the position D where the valve is locked closed. The string may be picked-up to move the lug to the position A' in readiness for opening the valve by setting down the string. The slotted sleeve 101 and lug may be dispensed with.
