Title: Orthoformic acid dialkylester amides and a process for the production thereof
IPC: C07D295/195
Filed: 1961-11-14
Abstract: The invention comprises the compounds of formula: <FORM:0951986/C2/1> where R and R1 are each an unsubstituted or substituted aliphatic, cycloaliphatic or aromatic radical or together form an alkylene bridge containing not more than 5 carbon atoms of which one methylene group may be replaced by oxygen, sulphur or secondary or tertiary amino, n is 0 or 1, and R11 is methyl when n is 0 or C1-4 alkyl when n is 1; and their production by reacting an amidinium salt of formula: <FORM:0951986/C2/2> where X is the anion of an inorganic acid, with an alcoholate of an alkanol containing 1-4 carbon atoms in the presence of an aliphatic alcohol containing 1-4 carbon atoms; the two alcohols may be the same.  The preferred reaction temperature is from -40 DEG C. to +50 DEG C. R and R1 are preferably C1-4 aliphatic radicals, C5 or C6 cycloaliphatic radicals, phenyl or naphthyl, any of which may be substituted, e.g. by C1-4 aliphatic or alkoxy radicals, and halogen atoms; or make up e.g. morpholine, thiomorpholine, piperidine or pyrrolidine rings.  X is preferably the anion of HCl, HBr, HI, HClO3, HIO3, HClO4 or H2SO4.  Specified alcoholates are alkali metal alcoholates of methanol, ethanol, n-propanol, isopropanol and n-butanol.  Examples and suitable starting materials are listed.  The reaction between N-methyl morpholine and phosgene produces chloroformic acid 3-oxapentamethylene amide, which with N-formyl morpholine gives N,N,N1,N1-bis-(3-oxapenta-methylene)-formamidinium chloride. Specification 899,060 is referred to.

The closure member 6 is operated by a mechanism comprising a toothed rod 9 axially displaceable by a piston and cylinder 8, a gear 10 and a link 11, hydraulic fluid being supplied to the cylinder through a magnetic valve 19. Closure member 15 is operated by a piston and cylinder 16 which is supplied with hydraulic fluid through a magnetic valve 20. With the slide 15 in its closed position and the closure member 6 in its open position, as shown in Fig. 4, closure of a two-handed double starter switch 25 causes closing movement of the member 6 to be effected. At the end of its stroke, the rod 9 actuates a limit switch 18 to operate magnetic valve 20 thereby causing slide 15 to open. At the end of the stroke of slide 15, a cam 24 operates a limit switch 17 which, via a control switch S, actuates a magnetic valve 22 to initiate a rapid feed movement of a slide 3 carrying a workpiece spindle tail piece 4. A cam 26 opens a switch 27 thereby energizing a holding relay 28 for the magnetic valves 19, 20. The opening of member 6 and closing of side 15 are initiated simultaneously but the slide 15 moves more rapidly than the member 6.

A tandem master cylinder for an hydraulic braking system for vehicles comprises a first (5) and second (23) pistons, a first spring 43 interposed between the pistons and a second spring 33 interposed between the second piston 23 and an end plug 2 closing the cylinder 11, a first chamber 18 between the pistons communicating with one brake circuit on the vehicle through an outlet 22 and a second chamber 26 between the second piston 23 and the end plug 2 communicating with the other brake circuit of the vehicle through outlet 35 and characterized in that the first spring 43 is mounted under a higher preload than the second spring. The pre-loading of the first spring 43 is achieved by providing a unit such as that shown in Fig. 2 positioned between the first and second pistons as shown in Fig. 1. Upon actuation of the master cylinder the first piston 5 is moved to the left and the pre-load of the spring 43 exceeds the pre-load on spring 33 the latter is compressed first and the pistons 5 and 13 perform simultaneously the movement in the direction of the plug 2 until the communication of the compression chambers 18, 34 and their respective reservoirs is simultaneously cut out.
