Title: Dibenzo (b,f)-1,4-oxazepine useful as tear gas - is prepd. by ketalisation of a nitro-phenoxy benzaldehyde, redn. and hydrolysis
Inventor: TAMBUTE ANDRE
IPC: C07D267/20
Filed: 1976-04-15
Abstract: Prepn. of dibenzo b,f. -1,4-oxazepine by (a) ketalisation of 2-(21-nitrophenoxy)-benzaldehyde using a 1-6C alkandiol or a 1-6C alkyl orthoformate; (b) redn. of the 21-nitroketal to the corresp. 21 amino-ketal and (c) hydrolysis of the 21-amino-ketal to the desired prod. Step (a) is pref. effected using the diol, e.g. ethyleneglycol, with an acid catalyst in an aromatic solvent with azeotropic distn. of water, esp. using benzene, toluene or xylene. Used as a tear-gas for maintaining public order, having a wide safety margin, limited sec. effects, good dispersing qualities, high stability and does not cause irreversible lesions. The known method of prodn. is hazardous and gives poor or variable yields. The present process gives better yields of sufficiently high purity.

Title: Automatic overload circuit breaker reset - is automatically actuated after transient-induced overvoltage and has separate DC supply
Inventor: NEUMANN GERARD
IPC: H01H75/04
Filed: 1977-03-23
Abstract: Automatic reset mechanism for circuit breakers installed in various electrical installations to protect against over-voltage and subsequent damage. The reset system allows the cut-out to move back into its 'ON' position after the system has been tripped by a short lived transient, as may occur during thunderstorms. The reset employs a separate electrical D.C. supply and a motor with reduction gearing operating a cam system. A lever engages with a contact system housed in a sliding compartment which acts downward onto the reset button. The lever itself is operated by a cam on a single cycle of rotation of the motor gearing, the cam working against a helical spring.

Title: Metal cathode for electrodeposition of metals - has V=shaped or U=shaped periphery to prevent metal deposition inside it
Inventor: BALTENNECK SERGE
IPC: C25C7/02
Filed: 1977-04-21
Abstract: Metal cathode for electrolytic deposition of metals, has at its periphery, at least in the region immersed in the electrolyte, a V- or U-shaped seating, the opening of which is directed outwards and into which is introduced one of the edges of an insulating, plastic or elastic strip, the width of which is greater than the depth of the seating. Used for electrodeposition of Cu, Ni, Co, Mn, Au, Ag, Pt, etc. or their prepn. by electrolytic refining, esp. in thin sheets removable from the cathode substrate. The seating prevents deposition of metal at the edge in such a way that it cannot readily be removed. It prevents formation of functions between the deposits formed on the two faces of the cathodes. Hence removal of the deposit from the substrate is facilitated.
