Patent GB-646220-A (GB)
Title: Improvements relating to the production of arecoline
Filed: 1948-01-12
Abstract: Arecoline is synthesized from bis-(b -cyanoethyl)-amine by the following steps: (1) methylation to give bis-(b -cyanoethyl)-methylamine; (2) treatment with methanol or ethanol to yield bis-(b -carbalkoxyethyl)-methylamine; (3) ring-closure to 1-methyl-3-carbalkoxy-4-piperidone; (4) hydrogenation to 1-methyl-3-carbalkoxy-4-hydroxy-piperidine; and (5) dehydration of the latter yielding arecoline if methanol was used in step (2) or homoarecoline if ethanol was used; in the latter case, the product is converted into arecoline, e.g. by hydrolysis to the free acid and re-esterification with methanol, or by ester interchange.  In step (1), bis-(b -cyanoethyl)-amine, obtained as a by-product in the manufacture of b -alanine and purified if necessary, e.g. by distillation, may be methylated with formaldehyde and formic acid and the product converted into the hydrochloride or sulphate.  Step (2) may be carried out with 20 per cent methanolic or ethanolic hydrochloric or sulphuric acid.  Step (3) may be performed with the aid of an alkaline condensing agent (e.g. an alkali metal or its methoxide, ethoxide, amide or hydride) in an inert solvent (e.g. naphtha or other hydrocarbon), the alcohol split out being removed by distillation. The resulting alkali enolate is acidified to give the free keto-ester which is extracted with chloroform and converted into its hydrochloride.  The hydrogenation step (4) may be carried out in methanol or ethanol under pressure, using Adams' platinum oxide catalyst.  The reaction is facilitated by the addition of a small amount of the free piperidone ester, or of an inorganic base which generates it from the hydrochloride present.  In step (5), the dehydration may be effected with thionyl chloride or phosphorus oxychloride in the absence of a solvent, the product being neutralized with a weak base and the arecoline or homo-arecoline extracted with chloroform.  Alternatively, dehydration may be effected with hydrochloric or hydrobromic acid or in the presence of a solvent (e.g. pyridine or a hydrocarbon) but low yields are obtained and hydrolysis may occur to the free acid which must then be re-esterified.  A certain amount of the D  -4 : 5 isomer is found during the dehydration, and the desired product may be freed from this by dissolving the mixture in an alcoholic solvent, treating the solution with hydrobromic acid and crystallizing out the hydrobromide.

Title: Improvements in or relating to inter-communication telephony by carrier system
IPC: H04B3/54
Filed: 1939-03-11
Abstract: 530,679. Diplex wireless signalling. HARDINGE, J. H. C. VON D., and ALEXANDER, C. G. March 11, 1939, No. 903. [Class 40 (v)] Intercommunication carrier telephony over power wires is effected between several stations by each station transmitting on a carrier of a frequency pertinent to the distant receiver, and for calling purposes modulating the carrier with a frequency pertinent to itself. The drawing shows in its upper part the transmitter and in its lower part the receiver of any one station. The output of the microphone M is amplified by valve V1 (section b) and is applied to a modulator valve V2 (section a), in the anode circuit of which is a speech coil controlling the modulation of a carrier oscillator V1 (section a), the frequency of which is selected by a switch S1 set according to the distant station. For calling purposes valve V1 (section b) is used as an audio frequency oscillator, the oscillations of fixed frequency being determined by a winding of the transformer Tl and a condenser C5. Anode current for the transmitter is supplied by valve V2 (section b). Incoming signals are applied to a valve V3, the anode d1 acting as a demodulating diode, the anode and grid b as an audio frequency amplifier and the anode d2 as a gain control diode, the output from this valve is amplified further by the valve V4 (section a) and applied through a high pass filter to a speaker S. Incoming calling signals, which are lower in frequency than speech currents are applied to tuned circuits C11, T3 and operate neon call indicators, which indicate the station originating the call. Anode current for the receiver is supplied by valve V4 (section b).

Filed: 1988-01-05
Abstract: PURPOSE:To measure the displacement, etc., of a body at a remote position with high accuracy by simple constitution by providing a light source and reflecting bodies, and a reflecting member and a light position detecting means. CONSTITUTION:Light projected by the light source 7 is transmitted through a half-mirror 9 and incident on a scanning mirror 11. The mirror 11 is driven 19 and positioned at a specific tilt angle, so the light incident on the mirror 1 is reflected in a set direction to strike on one of reflection bodies 13. The light incident on the reflecting body 13 is reflected here to strike on a corresponding reflecting member 1 of a main reflecting mirror 3. This light incident on the member 1 is reflected in a direction parallel to the incident light to travel to the reflection body 13. Then the reflected light is reflected by the reflecting body and mirror 11 to enter a two-dimensional sensor 15. Further, a signal processing part 17 performs arithmetic processing based upon the detection signal of the sensor 15 and the quantity of displacement of the main reflecting mirror 3 is outputted.
