Title: Improvements in installations comprising a plurality of free-piston engines
IPC: F02B71/06
Filed: 1956-03-28
Abstract: 789,426. Free-piston engines. SOC. D'ETUDES ET DE PARTICIPATIONS EAU, GAZ, ELECTRICITE,. ENERGIE SOC. ANON. March 28, 1956 [March 31, 1955], No. 9744/56. Classes 7(1) and 7(2) In an installation comprising a plurality of free piston engines (e.g. gas generators) the pneumatic accumulators are interconnected and the pistons reciprocate in phase with one another. Fig. 1 shows an installation comprising a pair of gas generators the pistons of which operate constantly. in phase. The cushion chambers 2b are interconnected by a conduit 14 and like quantities of fuel are injected into the cylinders. A single stabilizer may be provided for the two generators. As shown this comprises a valve 15 which admits gas to the cushion chambers from the air reservoir 10 or releases it therefrom through a port 25. The mean pressure in the cushion chambers acts on the underside of the piston 22. The pistons may be started in phase by supplying air into the cushion chambers from a pipe 27 and then operating the valve 28 so that the air pressure on the cushions actuates a piston 32 which moves abutments 26 and releases the pistons. The fuel control racks may be connected together or there may be a common injection pump for the two injectors. It may be desirable to. limit the in phase operation of the pistons for example to starting speed and sometimes the speeds immediately succeeding starting. In Fig. 2 the duct 14 includes a shut off valve or cock 37. When the duct is open the pistons operate in phase. When the valve 37 is closed the device 39-47 becomes operative and produces a phase difference of 18 degrees between the two generators. Duct 45 is a calibrated duct so that the means pressure in the cushion chambers acts on the underside of the piston 41a. In a modification the duct 14 is omitted and means are provided to keep the valve 40 open when desired. This means may comprise valve by which the space under the piston 41a may be connected to atmosphere. In practice the generators will usually comprise two opposing double pistons connected together in the usual manner by a synchronizing system. There may be more than two generators having their pneumatic cushion chambers connected together by ducts. The invention is applicable to free piston compressors. The reservoirs 10 are preferably connected by a duct 13. Specification 633,863 is referred to.

Title: Process for producing porous pharmaceutical compositions for tabletting
Inventor: KURAMOTO ROY
IPC: A61K9/14
Filed: 1990-12-21
Abstract: The preparation of pharmaceutical powder compositions which are directly compressible into tablets, is disclosed. The disclosed process includes subjecting an aqueous slurry/solution of a pharmaceutically active drug specifically naproxen or naproxen sodium (which slurry may be directly obtained without drying from the synthesis of the drug), alone or in admixture with an aqueous mixture of excipient materials, to a controlled form of spray drying to produce a dry powder of uniform particle size wherein the drug is uniformly dispersed in and coated with the excipients. The powder can be readily combined with additional dry excipient materials and formed into tablets. The process provides for substantial savings in the manufacture of the tablets. The spray dried powder compositions are highly compressible. Utilizing such spray dried powder compositions, the tablets formed are readily dissolvable and also are stable under normal storage conditions and stress conditions of temperature and relative humidity.
