  • Patent number: 4230236
    Abstract: This invention relates to a container for generally cylindrical tablets which can be used to repeatedly dispense the tablets in pre-determined quantities. The dispenser comprises an outer case and a slidably mounted inner part which together define a container, a dispensing gate, and a downward sloping channel connecting one or two ramps situated at the base of the container to the gate. The width of the channel is such as to allow a single column of tablets supported on their peripheries. The inner part is depressable from the exterior to cause relative movement between the gate and the channel from one position where the gate is in register with the channel to a second position where the gate is in register with a dispenser outlet. The relatively simple design of the dispenser enables it to be injection-moulded from plastic material.

  • Patent number: 4209638
    Abstract: Disclosed is a process for increasing the proportion of a desired enantiomer of a 2-arylpropionic acid which comprises heating at a temperature of at least 80.degree. C. a mixture comprising an inert liquid organic diluent and a salt of the 2-arylpropionic acid with an enantiomer of a chiral organic nitrogenous base, the base and the diluent being such that the salt of the racemic acid has a solubility of 0.1 to 10% w/v in the diluent at the operating temperature and in which process a proportion of the salt is undissolved in the diluent, whereby a proportion of one optical isomer of the acid component of the salt is converted into its enantiomer, and collecting the salt of which the acid component has an increased proportion of that enantiomer.
