Title: Therapeutic compounds and preparation thereof
Filed: 1964-08-07
Abstract: The invention relates to compounds of the formula <FORM:1019128/C2/1> in which R and R1 are alkyl groups of 1-5 carbon atoms. The compounds may be prepared by (1) forming a trifluoromethylpropiophenone, (2) halogenating this to form an a -halotrifluoromethylpropiophenone and (3) aminating the latter with an appropriate dialkylamine. Reaction (1) may be effected by treating a trifluoromethylphenyl magnesium halide with propionic anhydride at below 0 DEG  C. in an anhydrous solvent, or alternatively by treating a trifluoromethylbenzonitrile with ethyl magnesium halide to form an intermediate ketimine, which is then hydrolysed with aqueous mineral acid.  Reaction (2) is preferably affected at a temperature up to 100 DEG  C. with elemental bromine or chlorine, but other halogenating agents may also be used, e.g. N-bromosuccinimide, N - bromacetamide, sulphuryl chloride or N-chlorosuccinimide.  Reaction (3) may be effected at 50-125 DEG  C. in the presence of a solvent, which may be an excess of the dialkylamine. The products may be converted into salts, e.g. with hydrochloric, sulphuric, phosphoric, acetic, citric or benzoic acid. Examples are given of the manufacture of the hydrochlorides of a -diethylamino-o-, -m-, and -p-trifluoromethyl - propiophenones.  The products are of therapeutic value (see Division A5).ALSO:As anorexigenic agents in pharmaceutical compositions, use is made of compounds of the formula <FORM:1019128/A5-A6/1> in which R and R1 are alkyl groups of 1-5 carbon atoms (see Division C2).  The compounds may be used in the form of their salts.  They may be mixed with solid or liquid pharmaceutical carriers suitable for oral or suppository administration, and examples are given of the preparation of tablets containing a -diethylamino-m-(or p-)-trifluoron methylpropiophenone hydrochloride.  The compounds may also be included in food supplement compositions, e.g. in vitamin compositions, or used with other therapeutically active compounds, such as sedatives or laxatives.

Title: Improvements in or relating to coin testing devices
IPC: G07D5/08
Filed: 1936-11-27
Abstract: 487,866. Testing coins ; magnetic separators. BRECKNELL, MUNRO, & ROGERS (1928), Ltd., and DOLMAN, H. J. Nov. 27, 1936, No. 32478. [Class 27] [Also in Group II] A coin is led by a shoot 13, Fig. 1, to a counterweighted carrier 4 pivoted at 3, in which it lies between the poles of an electromagnet 12 energized with alternating or pulsating current. The carrier 4 is slightly off-set in relation to the magnet, so that the repulsion of the magnet due to the eddy currents induced in the coin tends to turn it anticlockwise. This is opposed by the weight of the carrier with the coin in it, the carrier lying to one side of the perpendicular through the pivot 3. The coin, on entering the carrier, releases a catch 5 normally locking the carrier, and if the coin is genuine the magnetic repulsion is sufficient to turn the carrier anticlockwise to discharge the coin into a shoot 14. If the coin is not genuine, the carrier turns under gravity in the opposite direction and discharges the coin into a second shoot 15. In the modified arrangement shown in Fig. 6, the carrier 4 is prevented from turning in the direction to release spurious coins by a stop 16. Such coins are released by the action of a lever 17 which turns the carrier in the same direction (clockwise) as in the case of genuine coins under the action of the electromagnet, but are diverted from the shoot 14 receiving genuine coins by a deflector 20 connected with the lever. The lever 17 may be actuated to discharge defective coins by operation of a push-button or-delivery drawer of the associated coin-freed apparatus, or by means of a time delay mechanism set in operation as the coin is inserted.
