Patent GB-558774-A (GB)
Abstract: 558,774. Heterocyclic substituted fatty acids and their amides. SOC. OF CHEMICAL INDUSTRY IN BASLE. Jan. 1, 1942, Nos. 25 and 26. Convention dates, Jan. 16, 1941, and Sept. 12, 1941. Sample furnished. [Class 2 (iii)] Heterocyclic substituted fatty acids and amides thereof are prepared by heating a heterocyclic-aliphatic ketone with an ammonium sulphide or with an amine in the presence of sulphur. Parent materials mentioned include pyridine alkyl ketones such as pyridines, methyl ketones, and pyridine ethyl ketones, quinoline alkyl ketones such as 2-acetyl quinoline 8-acetyl quinoline and 3-acetyl quinoline, and 1-phenyl-4 acetyl pyrazole, and substitution compounds of the above. The reaction is preferably carried out in the presence of water and/or an organic solvent such as dioxane. Amines mentioned include dimethylamine, diethylamine and piperidine. In examples (1) Aqueous ammonium sulphide and sulphur is added to a dioxane solution of 3- acetyl pyridine to give on heating under pressure to 160‹C. for 6 hours pyridine-3- acetamide. The mother liquors from the crystallization of this compound give an alkaline hydrolysis, pyridine-3-acetic acid. (2)3- acetyl pyridine, sulphur, and ammonium sulphide are heated in a bomb tube at 160‹C. for 12 hours to give pyridine-3-acetic acid. (3) 8-acetyl-quinoline, diethylamine and sulphur are heated for 5 hours to 150‹C. and the product saponified with alkali to give quinoline- 8-acetic acid.

Preferably the fluid pressure medium is constituted by one of the heat exchange fluids passing through the stack. The end piece 11 is detachably connected via tie bolts 16 to the end piece 10 which is fixed. The two heat exchange fluids enter and leave the exchanger through connections 18 in the fixed end piece 10. Displacement bodies 17 are provided to keep the fluid-filled volume of the end piece 11 small. A gasket 15 seals the joint between the end plate 14 and end piece 11. Each plate 12 has a central heat transfer surface 25 surrounded by gasketed openings 20, 21, 28 and 29 for the supply and withdrawal of the exchange fluids to and from the spaces between adjacent plates. Apertures 22 and 23 located between the openings serve to convey the respective fluids through the stack while by-passing the plate heat transfer surfaces 25. The two fluids are arranged to flow in countercurrent manner.

A boot or shoe which can be elongated by one increment in size has a two part sole 20 and insole, a heel 24 underlying the juncture 58 between the sections of the sole 20, an upper 14 having an expandable section 34 overlying the juncture 58 and means for retaining the sole in its shortened or elongated condition. In a first embodiment a shoe 12 has an expandable portion 34 e.g. of crinkled leather, in the upper 14 and an expandable portion 37 in the welt 22. The insole 23 and sole 20 are both formed in two parts having skived overlapping edges 58 and a two part shank stiffener 40 is positioned between the sole 20 and insole 23. The shank stiffener 40 has two parts 42, 44 joined by rivet 46 and slot 48 connections, the part 44 being secured to the rear section of the shoe and the part 42 being secured to the forward section. A tongue 52 on the part 44 engages one of the two slots 50 on the part 42 to hold it in its shortened or elongated position. The heel 24 is secured to the rear section of the shoe by fasteners 26 and fasteners 62 hold the forward portion of the shoe in position.

Binary data (c) received in phase-modulated code is converted to NRZ form (k). The data (k) is passed via a low-pass filter whose output (d) controls a clock pulse circuit and is fed to a sampling circuit. The clock circuit generates pulses (b) at twice the input bit rate and also two pulse trains (a, e) 180 degrees apart, at the bit rate. Pulses (b) control the sampling circuit which outputs samples E 1 , E 2 , line (d). The samples are separated, by AND gates fed by clock pulses (a, e); to form signals (f, g) which feed respective bi-stables. The bi-stables outputs (h, i) feed a circuit which subtracts one from the other, the resulting signal (j) passing to a threshold unit.

The member is a pivotal lever 33 which can be foot-operated by means of an extension 41 movable inwardly and outwardly of the panel by a Bowden cable 43. The lever 33 can be locked in its lower position (with the strips 17 retracted) by means of a rod on the lever engaging beneath a stop on the panel's frame, Figs. 1 and 2 (not shown). Alternatively, the lever can be so locked by a plate 49 secured to the lever 33 and slidable in a guide 51, a ratchet 48 having a pivot 53 slidable in aligned slots 57, 58 in the plate 49 and guides 51, and a spring-loaded finger 54 pivoted to the plate 49.

The welding of the plates in areas 7 is done by spot welding, whereas welding of edges 4 may be by resistance or gas welding, the latter allowing several radiators to be welded simultaneously in a stack. The sealed radiator unit is machined using a bit (18), Fig. 2 (not shown), at closed ends 8, 9 to form openings 11 for insertion of pipe joint components 19, e.g. by arc welding, gas-shielded welding, gas welding, or hard soldering of surfaces 12-14 at areas (15)-(17), Fig. 4 (not shown). The bit (18) preferably has the shape of a truncated cone so that a frustoconical joint, Fig. 6 (not shown), may be attached to the unit. An internal thread (25) receives the end of a pipe, Fig. 5 (not shown) to which a valve can be attached. The shape of the machined opening 11 can be varied according to the type and manner in which the pipe joint component is to be attached. The component can also be a threaded or unthreaded piece of pipe and may be supported by an installation guide jig so that the component is correctly aligned during installation.
