These processes may be effected in any order. Simultaneous keto and side chain reduction, e.g. 10A &c.*14A, is also effected by catalytic hydrogenation using Pt, Raney nickel and other catalysts. 14A includes isodihydroprostaglandin F 1[alpha] and like compounds. 15 includes dihydroprostaglandin F 1[alpha] and like compounds, obtained by reduction of 10A, 10B, 10C and 10D under conditions leading to rearrangement of the unsaturated side chain at the point of attachment to the cyclopentane ring, e.g. by hydrogenation at above room temperature in the presence of a hydrogenmobilizing catalyst, with, when required, hydrolysis of the acetal grouping. Hydrolysis of the ester group of compounds 10A-D, 11, 12A-D, 13, 14A, 14B and B is effected by conventional procedures the thus-obtained free acids may be re-esterified or converted to salts. Similarly, free hydroxy groups may be acylated and acyloxy groups hydrolysed. Wittig reagents of the formula are prepared from triphenylphosphine and an appropriate halo-acid or -ester with subsequent basification of the phosphonium halide first formed. The novel cyclopentane derivatives of the invention, which are used in the treatment of hypertension, may be made up into pharmaceutical compositions with suitable carriers.

Title: Recirculation plate type evaporators
IPC: B01D1/22
Filed: 1967-03-14
Abstract: In an evaporator comprising a pack of heattransfer plates, clamped in a frame, wherein liquid-to-be-evaporated flows up and down through alternate passages between the plates and heating-medium such as steam flows through the other passages, the plates are divided into two groups P 1 , P 2 by a partition or grid G having an aperture X through which steam, supplied through header L, can flow from plate-group P 1 to plate-group P 2 . The feed liquid is introduced through conduit A into group P 1 , and the mixture of vapour and partial concentrate, formed within this group, flows through port Z to cyclone separator S. The separated partial concentrate is pumped to the inlet C of plate-group P 2 . The mixture of vapour and final concentrate is drawn into the port Z in grid G where the final concentrate collects in sump D, and is withdrawn at J. The vapour flows on to separator S. In a modified manner of use, the feed liquid is introduced at C, the partial concentrate is removed from sump D, and then re-introduced at A. The plates may be divided into more than two groups by adding further grids to the assembly. The grid, or grids, may be moved along the frame on rollers R.

Title: Liquid-heating or steam generating apparatus
IPC: A47J27/04
Filed: 1969-03-29
Abstract: An electrode boiler comprises a vessel A, B, C a water inlet pipe E and an outlet pipe F in the cover B of the vessel two " submerged " electrodes L, C at the lower part of the vessel and connected to terminals I, J respectively and a perforated grid M electrically connected to one of these terminals and positioned between the upper electrode L and the orifices of the pipes E, F to completely screen the orifices from scale rising from the electrodes. The cover B may be completely isolated from the supply circuit or may be the same polarity as the grid. The pipe F which supplies steam to a receptable R containing liquid to be heated terminates in a check valve N biased closed by a strong spring. Thus when the supply of steam is terminated valve N closes and prevents liquid being sucked into the pipe F. An air supply valve O biased closed by a weak spring and included in the water supply pipe allows air to enter the vessel AB, C when the steam pressure is reduced so that the difference in pressure between the water supply and the boiler is reduced and prevents ramming. In Fig. 2 (not shown), the vessel comprises two cup-shaped parts electrically connected and mechanically sealed together. The perforated particle filtering grid is electrically connected to and trapped between the cup-shaped parts. The other electrode is mounted on a rod projecting through and insulated from the base of the vessel.

Several other phosphite diesters which are stated to be novel are specified.
Patent ES-379076-A1 (ES)
Title: Installation to produce rapidly a heated fluid
IPC: F22B21/06
Filed: 1970-04-25
Abstract: A multitubular boiler is substantially symmetrical about an axis XY which is vertical as shown but may be up to 60 degrees from vertical. The top and bottom torroidal reservoirs 2, 1 are interconnected by three banks of vertical water tubes 3, 4, 5 which are bent at their ends to meet the reservoir surfaces perpendicularly. As indicated by arrows F1-F4 the hot gases from burner 8 pass down the centre of the boiler and are deflected around tubes 3, 4, 5 by a baffle 11 closing the reservoir 1 and annular baffles 6, 7 extending from the bottom reservoir 1 to near to the top reservoir 2 and vice versa. Finally the gases leave through bore 18 and flue 15. The water tubes may be replaced by annular water vessels having apertures for the hot gases to pass through. The boiler is enclosed by a removable insulation jacket 12 which may be surrounded by a water tank 16, 17 for preheating feedwater. Cleaning jets for steam or compressed air are provided in tubes 9, 10 for the removal of soot deposits. In hot water production cold feedwater rises through pipes 3, 4, 5 in parallel. In steam generation feedwater is introduced into the top reservoir 2 which is kept half full of water and after partly mixing with heated water descends through the cooler outer tubes 4 to reservoir 1 and returns through hotter tubes 3, 5 where steam is generated. In an alternative form for the production of both steam and hot water a third torroidal reservoir intercepts the tubes 3, 5 and thus rising hot water flows through it before entering upper reservoir 2. A further bank of tubes may be provided for superheating.
