Title: Improvements in or relating to substituted piperidines
Filed: 1953-04-01
Abstract: The invention comprises: (a) carbinols of the general formula: <FORM:0765854/IV(b)/1> wherein Q is phenyl, Q1 is phenyl or pyridyl, one of R and R1 is hydrogen and the other a hydroxy group, and R2 is hydrogen or an alkyl group of 1-6 carbon atoms, and salts of certain of these compounds; (b) the preparation of the compounds in which R is a hydroxy group and R1 is hydrogen by reacting a ketone QCOQ1 with a methylpyridine to form a carbinol, reducing this to a pipecolyl carbinol, and, if desired, subjecting the latter to reductive alkylation; (c) the preparation of the compounds in which Q1 is pyridyl, R is hydrogen, R1 is a hydroxy group and R2 is methyl by reacting a lithium substituted benzylpyridine with a 1-methylpiperidine aldehyde; (d) conversion of the products of (b) and (c) to acid addition and quaternary ammonium salts.  In examples: (1) benzophenone is reacted with 4-picoline in the presence of sodamide and the resulting diphenyl 4-picolyl carbinol is hydrogenated in acetic acid in the presence of platinum to produce diphenyl 4-pipecolyl carbinol, the hydrochloride of which is described; (3) 3-picoline similarly yields diphenyl 3-pipecolyl carbinol; (3) 2-picoline similarly yields diphenyl 2-pipecolyl carbinol; (4) the product of (3) is refluxed with formalin and formic acid to form diphenyl 1 - methyl - 2 - pipecolyl carbinol, the oxalate of which is described; (5) the product of (4) is quaternated with methyl bromide in ether; (6) lithium is reacted with bromobenzene in ether and the product with 2-benzylpyridine, and the resulting solution is stirred with an ethereal solution of 1 - methyl - 4 - piperidine aldehyde to produce a  - (2 - pyridyl) - benzyl 1 - methyl-4 - piperidyl carbinol; (7) the product of (1) is shaken with formalin in methanol, after which Raney nickel is added and the mixture hydrogenated under pressure to give dimethyl 1-methyl-4-pipecolyl carbinol.  The products are useful as antispasmodic agents, especially in the form of their acid addition and quaternary ammonium salts (e.g. sulphates, phosphates, hydrochlorides, levulinates, mucates, acetates, tartrates, methobromides and methiodides), and as intermediates in the process of Specification 765,853.ALSO:Therapeutic preparations for the relief of smooth-muscle spasms contain carbinols of the general formula:- <FORM:0765854/VI/1> (wherein Q is phenyl, Q1 is phenyl or pyridyl, one of R and R1 is hydrogen and the other a hydroxy group, and R2 is hydrogen or an alkyl group of 1-6 carbon atoms) or an acid addition or quaternary ammonium salt thereof.  These compounds may be employed in the form of an aqueous solution of a water-soluble salt (e.g. of sulphuric, phosphoric, hydrochloric, leonlinic, mucic, acetic or tartaric acid) or incorporated in a tablet or capsule base.  The free bases or their sparingly soluble salts may be administered when a slow and prolonged effect is desired.

Title: Improvements in or relating to band pass coupling circuit arrangements
IPC: H04B1/16
Filed: 1945-12-07
Abstract: 602,785. Automatic selectivity control. RUDKIN, E. P., and STANDARD TELEPHONES & CABLES, Ltd. Dec. 7, 1945, No. 33219. [Class 40 (v)] A variable selectivity band-pass filter comprises at least two coupled resonant circuits with means for applying regeneration to at least one circuit, the signals passing through the filter simultaneously, causing the coupling to increase and the regeneration to decrease. The intermediate frequency amplifier 3, Fig. 1, feeds amplifier 4 over tuned circuits 1, 2 having link circuits 5, 6 connected in opposition. Each of the tuned circuits 1, 2 feeds a valve 15, 14 providing regeneration to its associated circuit, the link circuits 5, 6 being damped by the impedance of valves 9, 8. The output from amplifier 4 feeds over a further amplifier 12, diodes 10, 13 and 11 supplying negative and positive central potentials. In the absence of a received signal, the coupling between circuits 1, 2 over link circuits 5, 6 is small and the regeneration at a maximum. With an increase of signal, diodes 10, 11 apply negative and positive potentials to valves 8 and 9 to vary the damping of the link circuits 5, 6, thus increasing the coupling between the tuned circuits 1, 2. The negative potential from diode 13 decreases the regeneration by biassing valves 14, 15 and is also applied as A.G.C. to valves 3, 4, 12. In a modification, Fig. 2 (not shown), the link circuits are replaced by valves fed in push-pull from the tuned circuits 1, 2, a common output-circuit being coupled to the other tuned circuit 2, 1, and in a further modification, Fig. 4 (not shown), single valves may be employed. In a further modification, Fig. 3 (not shown), the band-pass filter comprises two tuned circuits coupled by a capaciter, the value of which is varied by means of a reactance valve. In a further modification, Fig. 5 (not shown), control of potentials are also derived from an auxiliary amplifier tuned to an interfering signal or to a band of frequencies subject to static interference and are applied in opposition to the potential derived from the main signal channel. The circuit is arranged to allow potentials derived from the interference to increase the regeneration up to the maximum without self-oscillation commencing, any further increase being ineffective, whereas the coupling is decreased continuously. The control potentials from the main signal channel and the interference amplifier may be applied to separate stages of the I.F. amplifier, Fig. 6 (not shown).
