Abstract: This is a hitch for a connection between a bicycle and a trailer. The hitch includes a connector which is secured to the axle of the rear wheel of the bicycle. A joint extends between the connector and a rotatable tube. The rotatable tube is connected to the tongue of the trailer so as to form the hitch having three axes of pivot.

Abstract: An alkyl .alpha.-cyanoacetate is reacted with ammonia in a glycol solvent medium to form cyanoacetamide. Advantageously and without requirement of separation of the formed cyanoacetamide in glycol solvent (even though the next step and entire procedure can optionally commence with pre-formed cyanoacetamide), 2,2-dibromo-3-nitrilopropionamide is formed in situ by treating the cyanoacetamide in glycol with an appropriate mixture of bromine and an alkali metal bromate at about 10.degree. C-40.degree. C. Excellent and stable antimicrobial compositions may then be prepared, as part of an overall integrated process by incorporating in the resultant 2,2-dibromo-3-nitrilopropionamide-containing reaction mass an appropriate quantity of paraformaldehyde or equivalent satisfactory stabilizer at a suitably adjusted pH level.
