Title: Spasmolytic, antitussive agent - i.e. N-(3,5-diiodo-2-acetamidobenzyl)-N-methyl cyclohexylamine hydrochloride
IPC: C07C233/00
Filed: 1974-07-05
Abstract: The cpd. of formula (I) is stated to be new: Claimed is a process for preparing (I) (see below) and compsns. contg. (I) Spasmolytic, antitussive. By refluxing 1-bromoethyl-3,5-diido-N,N-diacetylaniline with N-methylcyclohexylamine. Mouse LD50 i.p. is 260 mg./kg. A dose of 5.3 mg./kg. i.v. in the guinea-pig gives 37.5% inhibition of acetylcholine-induced and 66.6% inhibition of histamine-induced broncho-constriction. A mixture of 1-bromoethyl-3,5-diiodo-N,N-diacetylaniline (5.25 g.) and N-methylcyclohexylamine (1.125 g.) in ethanol (100 ml.) was refluxed for 8 hr., the ethanol was distilled and the residue was washed with ether to give a solid. This was refluxed for 2 hr. with 2N HCl (150 ml.), the mixture was cooled to 4 degrees C for 8-12 hr. The crystals which separated were collected, washed with water and crystallized from ethanol/light petroleum (1:1) or in acetic acid/water (1:1) to give (I), m.pt. 195-6 degrees.
Patent FR-2279933-A1 (FR)
Title: IC engine with opposed pistons in each cylinder - has rollers transmitting drive to cam on output shaft
IPC: F01B9/02
Filed: 1974-07-25
Abstract: The engine has one or more cylinders (1) with a cap (2) at each end which houses the poppet type exhaust valve. Each cylinder has two pistons which are connected by four rods and the spaces between these rods allow the output shaft to pass through the piston and provides room for the circular cam to rotate. Rollers are attached to the pistons so that they transfer the piston force to the cam and thus convert the reciprocating motion of the piston to rotary motion of the output shaft. The principle can be applied to supercharged two-stroke engines with compressors (4) and exhaust ports (3).
