Title: Combined fuel injector and injection pump
IPC: F02M59/26
Filed: 1961-04-19
Abstract: 974,768. Fuel injection pumps. LE MOTEUR MODERNE. April 19, 1961 [April 22, 1960; March 9, 1961], No. 14169/61. Heading F1A. In a combined fuel injection pump and injector operated by engine compression, hydraulic means are provided for timing the commencement of injection and damping the end of each stroke. The pump casing, Fig. 1, is maintained full of fuel via an inlet 25 and an outlet. Movement of the pump cylinder 2 over the fixed pump plunger 3 during the engine compression stroke is initially retarded by the flow of fuel from a chamber 4 to a chamber 5 via a needle valve 34, until the head 31 of cylinder 2 clears housing 1 permitting direct flow between the chambers. Rapid upward movement of cylinder 2 then occurs accompanied by injection of fuel from a chamber 18 formed beneath plunger 3. The setting of needle valve 34 determines the commencement of injection. The duration and hence quantity of injection is regulated by a cutaway 23, Fig. 3, in the outer wall of cylinder 2, which cutaway communicates with passages 20, 21, 22 to the pumping chamber 18 and with a port 24 from the fuel inlet. Cutaway 23 is rotated relative to port 24 by rotating cylinder 2 by a lever 38 and splines 40, 41. Damping at the end of each stroke is effected by the trapping of liquid on the upward stroke between the top of piston 7 and chamber 4 and on the downward stroke between the lower surface of head 31 and a seating formed in housing 1. In another embodiment, Fig. 6, the pump casing is filled with a separate lubricating and cooling liquid, via passages 71 and 72. Initial upward movement of a cylinder 57 is retarded until its head 58 clears a constriction 55, a needle valve 76 controlling the initial rate of movement, as before. A cutaway 94 controls a port 88 supplying a pumping chamber, below piston 63, via passages 95, 96, 97 from an inlet 69.

Title: Estradiol 17-ª -cyclopentylpropionate, its manufacture and preparations containing the same
IPC: C07J1/00
Filed: 1952-06-11
Abstract: The invention comprises estradiol 17-betacyclopentylpropionate, and the preparation thereof by esterifying estradiol to introduce the 17 - beta - cyclopentylpropionoxy radical and hydrolysing any ester radical formed at the 3-position.  The esterification may be carried out by treating estradiol with beta-cyclopentanepropionyl chloride or bromide in the presence of a tertiary organic base such as pyridine or dimethylaniline, or by an ester interchange of a lower-alkyl ester of beta-cyclopentylpropionic acid with estradiol, or by the azeotropic esterification of estradiol with beta-cyclopentylpropionic acid in the presence of benzene or toluene and p-toluene sulphonic acid or boron trifluoride.  The selective hydrolysis of any 3-ester radical may be accomplished by the action of potassium carbonate in aqueous methanol at about 20 DEG  C.  In an example estradiol-3, 17 beta - dicyclopentyl - propionate is prepared using beta-cyclopentanepropionyl chloride, and the 3-ester radical is hydrolysed to form estradiol 17-beta-cyclopentylpropionate.ALSO:A therapeutic composition comprises a sterile solution of estradiol 17-beta-cyclopentylpropionate in a non-toxic glyceride oil, e.g. a vegetable oil such as peanut, cottonseed, corn or sesame oil, or an aqueous suspension of microcrystalline estradiol 17 - beta - cyclopentylpropionate.  The solution may be prepared by dissolving the estradiol ester with stirring and gentle warming in the glyceride oil, or by dissolving the estradiol ester in a low boiling inert organic solvent such as ether, mixing the resulting solution with the glyceride oil and removing the organic solvent under reduced pressure.  Aluminium stearate may be added to the solution, e.g. by adding about 2 per cent by weight of aluminium stearate per volume of oil (gram-centimetre units) at room temperature, heating the solution to about 120 DEG C for about ten minutes and cooling.  The microcrystalline suspension may be prepared by preparing a solution of about 0.01 per cent of a quaternary ammonium salt and about 0.9 per cent of sodium chloride in water, gradually mixing this solution with the estradiol ester and diluting to the desired volume.
