Title: Concentration of aqueous methacrolein solution
Inventor: HOWLETT JOHN
Filed: 1951-01-30
Abstract: Aqueous solutions of methacrolein are concentrated by distillation under reduced pressure, e.g. 250-400 mm. of mercury, and at a pH of 5-8 in apparatus in which the parts coming into contact with concentrated methacrolein vapour, such as vapour lines, condenser and reflux systems are made from material incapable of giving ferric or ferrous ions to the condensate.  Polymerization is thereby inhibited. Hydroquinone or other inhibitor may also be added to the apparatus to further inhibit polymerization.  Suitable constructional materials are stainless steel, monel metal, aluminium, porcelain and plastics materials.  The Provisional Specification also refers to copper. Examples are given.  Specification 687,852 is referred to.ALSO:Aqueous methacrolein solutions are concentrated by distillation under reduced pressure, e.g. 250-400 mm. of mercury, and at a pH of 5-8 in apparatus in which the parts coming into contact with concentrated methacrolein vapour, such as vapour lines, condenser and reflux systems, are made from material incapable of giving ferric or ferrous ions to the condensate Polymerization is thereby inhibited.  Hydroquinone or other inhibitor may also be added to the apparatus to further inhibit polymerization.  Suitable constructional materials are stainless steel, monel metal, aluminium, porcelain and plastics materials. The Provisional Specification refers also to copper.  In an example a 0.3 per cent. aqueous methacrolein solution was fed at 15 gals./hour into a column comprising a mild steel stripping section 6 inches in diameter and 13 feet 8 inches long packed with 3/4 inch porcelain rings, surmounted by a 3 inch diameter stainless steel rectifying section 5 feet 2 inches long packed with 3/8 inch porcelain rings.  The vapour line and condensing system were also of stainless steel.  Six c.c. per hour of 4 per cent. aqueous hydroquinone was fed into the inlet of the condensing system.  At 400mm. of mercury pressure, kettle temperature of 82 DEG C. and still head temperature of 47 DEG C. the still was operated for 28 days with no polymer formation.  The condensate separated into two layers, the top having 97.2 per cent. and the bottom 7.6 per cent. by weight of methacrolein.  The still was also operated at 250 mm. pressure, with kettle temperature of 73 DEG C. and still head temperature of 36 DEG C. Specification 687,852 is referred to.
Patent GB-548301-A (GB)
Title: Signal collecting systems for radio receivers and the like
IPC: H03H2/00
Filed: 1941-02-19
Abstract: 548,301. Wireless receiving apparatus. JOHNSON LABORATORIES, Inc. Feb. 19, 1941, No. 2278. Convention date, Feb. 19, 1940. [Classes 40 (iii) and 40 (v)] A signal collecting system comprises an exposed inductive element inductively reactive throughout the tuning range, a fixed condenser and a transformer having an adjustable core adapted to tune the secondary winding and the fixed condenser to resonance. In this way when a small primary is used the falling frequency coupling characteristic of the transformer may compensate for the rising characteristic of the loop 1. A small coupling capacity between the high potential ends of the transformer windings may be used, Fig. 3 (not shown). Alternatively synchronous tuning of circuits 1, 2 and 3, 5 may be secured by tight coupling between the primary 2 and secondary 3 so as to cause a negative reactance to be reflected into the circuit 1, 2. When the primary circuit is tuned in this way the connection of the loop 27 to the transformer 28, 29 is preferably, as shown in Fig. 7, such that the reflected negative reactance is in series with the loop reactance and is shunted by the transformer mutual inductance, Fig. 8 (not shown). The mid point of the loop, Fig. 4 or the mid point of the transformer primary, Fig. 5 (not shown) may be earthed instead of the end of the loop so that the loop is balanced with respect to the capacitive field to prevent pick-up by the electrostatic signal component. The Specification gives inductances values and winding data for the coils and design formulae. Specifications 366,475, 455,573, [Group XXXVI], 547,369 and 548,695 are referred to.
