Abstract: The invention comprises steroids of the pregnane series having at carbon atoms 17, 20 and 21 the structure <FORM:0867786/IV (b)/1> wherein n represents 0, 1, 2, 3, 4, 5 or 6, and the preparation thereof by treating 17a , 21-dihydroxy-20-keto steroids of the pregnane series with aldehydes of the formula CnH2n41 CHO, where in n has the above significance, in the presence of a strong acid having a -log k of less than -2,25.  Suitable aldehydes mentioned are formaldehyde, acetaldehyde, propionaldehyde, n-butyraldehyde, n-valeraldehyde, n-caproaldehyde and n-heptaldehyde.  The pregnanes of the above formula may be 3-oxygenated and may also contain substituents such as hydroxy, keto, halo or lower alkyl substituents at position 2, 3, 4, 6, 7, 9, 11, 12, 14 or 15 of the steroid nucleus, and may be saturated or contain one or more double bonds in the nuclear e.g. attached to carbon atoms 1, 3, 5, 7, 11 or 14 of the steroid nucleus.  Thus the product may be a pregnane, allo-pregnane, 4-pregnene, 1-pregnene, 19-nor-4-pregnene, 1,4-pregnadiene, 4,6-pregnadiene or 4,9(11)-pregnadiene, and many such products are specified containing a 2-methyl substituent a 3-hydroxy or keto substituent, a 11-hydroxy or keto substituent, a 9a -hydroxy, chloro, bromo or fluoro substituent, a 12-fluoro or chloro substituent, a 6-methyl or hydroxy substituent, or a 9,11-oxido substituent.  In the examples the preparations of a number of compounds having the above general formula by the above method are described. Typical products prepared are the 17-20, 20-21-bismethylenedioxy derivatives of 4-pregnene-3, 11-dione, 1,4-pregnadiene-3,11-dione and 1,4-pregnadiene-3-one-11-methoxymethyl ether.  In addition, 17-20, 20-21-bismethylenedioxy-4-pregnene-3,11-dione is prepared by oxidising the corresponding 3-hydroxy compound.  2-Methyl-cortisone and 2-methyl-hydrocortisone are prepared by forming a 17-20, 20-21-bismethylenedioxy or a 17-20, 20-21 bis-substituted methylenedioxy derivative of cortisone and hydrocortisone by the above method, treating these derivatives successively with methyl oxalate and a methylating agent, and finally treating the 2-methyl-17-20, 20-21-bismethylenedioxy (or substituted methylenedioxy)-cortisone and hydro-cortisone with sulphuric acid. 4,6-Pregnadiene-17a ,21-diol-3,11,20-trione is prepared by treating the corresponding 17a , 21-diacetate with methanolic sodium methoxide.  Hydrocortisone acetate is prepared by heating the 17-20, 20-21-bis-n-butyraldioxy thereof with acetic acid, and acetylating the resulting hydrocortisone.  Specification 867,787 is referred to.

Title: Multiple plunger mel injection pump
IPC: F02D1/18
Filed: 1974-09-30
Abstract: 1462210 Fuel injection pumps ALLISCHAMBERS CORP 30 Sept 1974 [1 Oct 1973] 42356/74 Heading F1A In a multi-cylinder fuel injection pump of the kind comprising a plurality of reciprocable plungers 47 each having a surrounding axially and angularly movable sleeve 48 for controlling flow through a spill passage leading from the respective working chamber 50, the sleeves 48 are movable in unison by a control rod 43 connected through linkage to the control sleeve 12 of an engine speedresponsive device 11, the linkage being arranged to modify the movement of the control sleeve 12 transmitted to the control rod in dependence on the position of a throttle control lever 126 and a variable fulcrum timing control lever 70. The linkage comprises a drive lever 15 pivotable about a bolt 16 by the control sleeve 12 and comprising a quantity control arm 17 and a timing control arm 18. A pin 118 carried by the quantity control arm 17 is received in a slot (19) at one end of a torque link 20, the other end of which has a pin 24 received in a slot in the control rod 43. The torque link 20 is pivotable about a point (33) on a screw (32) carried by a drive link 76. The pin 24 also forms the pivot for one end of a throttle link 21 having a spring 22 tending to urge the links 20, 21 into alignment. At its other end the throttle link 21 is pivoted about an eccentric (25) on a throttle arm 23 fixed to a shaft rotatable by the manually controlled throttle lever 126. Thus the movements of the throttle lever 126 and the control sleeve 12 together determine the axial movement of the control rod 43 and hence by turning of the sleeves 48 the quantity of fuel delivered. Movement of the timing control arm 18 is converted into angular adjustment of the rod 43 through the drive link 76, the link 76 being arranged to pivot the timing control lever 70 and thereby raise or lower a timing link 73 connected by a universal joint to an arm fixed to the rod 43. The timing lever 70 is pivotable on an eccentric pin 71 of an angularly adjustable shaft 72 whereby both adjustment of the shaft 72 and movement of the drive link 76 alter the timing by rotating the control rod 43 and thereby either raising or lowering the sleeves 48. In another embodiment, Figs. 1-6 (not shown), the characteristics of the linkage are somewhat different due to the positioning of the pivot pin 72 closer to the rod 43.
