The smaller piston 8 has its piston rod 9 connected to the ram and is used to perform the hammering. The larger piston 12 presses against the upper surface 25 of the ram to move the ram for a pressing stroke. The fluid supply is controlled by a device 18. The lower chambers 22, 23 are connected to a pressure accumulator (not shown), for the return strokes. The larger piston 12 is held mechanically or hydraulically in its upper position during hammering. For pressing the pistons move downwards together. In a similar embodiment, Fig. 2 (not shown), the anvil 7 is mounted on a vertically slidable block (26) which is connected by vertical rods (28) to pistons (29). The cylinders of these pistons are connected to the device 18 by a conduit 31 to provide an initial upstroke of the anvil and a braking force for the ram. The piston cylinder devices to move the anvil may be provided in the frame of the machine adjacent the anvil, Fig. 3. In a further example, Fig. 4, the ram is used for hammering and the anvil is raised for pressing. The anvil is moved by a pair of pistons 36 connected to the anvil by rods 28 in place of the larger piston 12 of the first embodiment. A buffer 37 is provided for the ram. In a modification of this embodiment.

Title: New derivatives of l-ascorbic acid
IPC: A61K31/375
Filed: 1959-11-16
Abstract: The specification comprises 2,5,6 tricarbalcoxy-L-ascorbic acid esters of the formula:  <FORM:0869458/IV (b)/1> where R2 is an alkyl group containing from 1 to 3 carbon atoms.  Specified esters are 2,5,6 tricarbmethoxy-L-ascorbic acid ester and the corresponding ethoxy and propoxy esters.  These esters may be made by esterifying L-ascorbic acid or a salt thereof, or a derivative in which instead of the free OH groups present in the 5 and 6 positions these are replaced by organic or inorganic radicals which are capable of being easily hydrolysed to OH groups, such as the isopropylidene group, with alkyl esters of chloro- or bromocarbonic acid under alkaline conditions.  These conditions may be obtained by means of organic tertiary bases such as pyridine, lutidine or collidine.  In examples, 2,5,6tricarbethoxy-L-ascorbic acid ester is obtained by adding chlorocarbonic acid ethyl ester dissolved in acetone slowly to ascorbic acid or 5,6 iso-propylidene L-ascorbic acid in pyridine at O to -5 DEG C. and stirring for 2 hours, HCI gas is then added and the oil formed is dissolved in chloroform and shaken out with saturated sodium hydrogen carbonate solution.  This solution is acidified with concs HCI and extracted with ether.  After removal of the ether the light yellow syrup crystallises.  These esters are relatively thermostable and may be used in foodstuffs such as bread.ALSO:2,5,6-Tricarbalkoxy-L-ascorbic acid esters of the formula <FORM:0869458/VI/1> where R2 is an alkyl group containing from 1 to 3 carbon atoms, are used as a source of Vitamin C in foodstuffs, in particular bread, as they lose only 10% of their Vitamin C activity during heat treatment, e.g. baking or sterilization processes. Specified esters are 2,5,6-tricarbmethoxy L-ascorbic acid ester and the corresponding ethoxy and propoxy esters, which esters may be made by the methods described in Group IV (b).
