Title: New steroid compounds and processes for their preparation
IPC: C07J75/00
Filed: 1960-03-28
Abstract: The invention comprises 16a , 17a -methylene-20-keto-pregnane compounds which may be unsubstituted in the 21-position or contain a hydroxy or acyloxy group therein; and 3a -hydroxy-16a , 17a -methylene-21-diiodo-pregnane-11, 20-dione; and the preparation of the first-named group of steroids by hydrolysing an appropriate 16a , 17a -azomethylene-pregnane with a Lewis acid or a strong inorganic acid.  The second-named steroid is prepared in the process which comprises hydrolysing 3a -acetoxy-16a , 17a -methylene-pregnane-11, 20-dione to the 3a -ol, heating this in methanol with iodine in the presence of calcium oxide and calcium chloride to yield the 21-diiodo compound, reacting a solution of this in dilute acetic acid (with which it is separated from the calcium oxide formed) with a solution of an alkali metal acylate in acetone or dimethylformamide in the presence of the acid from which the alkali metal acylate is derived to form a 3a -hydroxy-16a , 17a -methylene - 21 - acyloxy - pregnane - 11,20-dione, oxidizing this to the 3-ketone, brominating this (which two last-named process may be effected in one step with N-bromosuccinimide in a tertiary aliphatic alcohol), and eliminating hydrogen bromide from the 4-bromo compound e.g. by treatment with a lithium halide-lithium carbonate couple, or through an intermediary hydrazone, to form the 16a , 17a -methylene,21-acyloxy-pregn-4-ene-3, 11, 20-trione.  Any of these 21-acylates may be hydrolysed to the corresponding 21-ols. Acyl groups are derived from aliphatic acids containing at most 6 carbon atoms.

Abstract: 1,032,814. Nuts; bolts. STANDARD PRESSED STEEL CO. March 20, 1963 [Dec. 31, 1962], No. 10997/63. Heading F2H. To prevent fatigue failure at the root of certain threads of a bolt member when engaged with a nut member, the members are provided with a thread system in which the internal threads of the nut member in unloaded condition have a progressively longer lead than the lead of the unloaded external threads of the bolt member and in addition the threads adjacent the lower bearing surface 11 of the nut 10 are counterbored at 12 to truncate the crests of from one to four threads adjacent the bearing face of the nut. The true pitch diameter of the internal and external, lead corrected threads is corrected to cause the virtual pitch diameter to approach the basic pitch diameter and thereby prevent an interference fit when in an unloaded condition. A positive correction for internal threads and a negative correction for external threads can be applied to either or both members. The invention is applicable to locknuts having threads displaced to a non-circular configuration and to castellated nuts.

Title: Improvements in or relating to air filter assemblies
Inventor: FIELD SIDNEY JAMES
IPC: B01D46/18
Filed: 1964-03-16
Abstract: A travelling-band air filter (1) and a stationary filter (2) operate in series, and the filter (1) is moved in response to an increase in the total pressure drop across filters (1, 2), whereby the said total is permitted to oscillate only within a narrow range, so that the air flow rate induced through the filters by a fan remains constant. Filter (1) is a web of bonded acetate material, wound off a supply spool (1a) and in a sinuous manner over perforate drums (1b) on to a motordriven roll (6).  Pressure switch (4) controls movement of roll (6) to maintain a total pressure drop of 1.15 to 1.25 inches of water.  To ensure that the initial pressure drop, with both filters clean, is within that range the web has an initial thick portion (5) of high resistance, followed by the normal web 7.  In the early stages, with filter 2 clean, the web builds up considerable deposit before being moved, but as filter 2 becomes contaminated and its own resistance builds up, the web is moved at relatively low degrees of contamination.  The arrangement is used in a ventilation system.

Title: Improvements in and relating to central buffing and draw gear for railway vehicles
IPC: B61G7/12
Filed: 1934-04-14
Abstract: 428,966. Combined buffing and drawgear for railway vehicles. SPENCER, A., and SPENCER MOULTON & CO., Ltd., G., 2, Central Buildings, Westminster. April 14, 1934, No. 11303. [Class 103 (v)] A combined buffing and draw-gear for railway vehicles, particularly adapted for transition use, comprises a housing 2 mounted on the end sill 1, a draw-head 3 pivotally and slidably mounted in the housing so as to permit angling of the draw-hook or automatic coupler, and transversely extending lugs 20, 21 on the draw-head to which are pivoted two rearwardly extending draw-rods 22, 23 adapted to co-operate with springs 7, 8 located within the housing 2 and actuated by the draw-rods. When draught stresses are exerted either with a draw-hook 13 or automatic coupler 14 in use, nuts 24, 25 on the rear ends of the rods 22, 23 cause the springs 7, 8 to be compressed against a front follower 15, and shoulders 16 on the housing. When the automatic coupler 14 is in use, buffing shocks are transmitted to the springs by the front follower, which consists of a casting 15 bearing laterally against pressure plates 33, 34 and having at its centre a cylindrical surface 19 to coact with a corresponding surface at the rear of the draw-head 3. In order to permit the springs 6, 7 to exert a centralizing effort on the draw-head, the pressure plates 33, 34 are caused to bear against shoulders 32 on the rods 22, 23. For guiding and preventing rocking movement of the draw-head in a vertical plane, it is provided respectively with upper and lower guide lugs 29, 30 working in longitudinal guideways in the housing 2 and with a rearwardly extending horizontal web 26. The springs are preferably of the compound metal and rubber type, but other forms may be employed. Specifications 195,034, 266,059, and 274,367, [all in Class 103 (v)], are referred to.

In a reciprocating pump for dispensing measured quantities, e.g. filling ampoules, etc. with pharmaceutical preparations, the pump plunger 20 is connected to reciprocating members 35, 36 carrying a roller 50 engaging a curved lever 51 oscillated by a crank 55 and connecting rod 57 and pivoted at 52 on a member 53 pivoted on the shaft 54 driven from an electric motor 61 through a variable friction drive 62. The amount delivered is varied by turning the member 53 about the shaft 54 by means of lever 85 so that the plunger 20 always moves to a constant point in its delivery stroke and the end of the suction stroke is varied. The liquid to be dispensed is drawn through valve 24 and delivered through valve 26 to the spout 28. To prevent drip at the spout, a secondary piston 22 is permitted to retract a small amount by the spring 32 at the beginning of the suction stroke of the piston 20. The upward stroke of the piston 20 is limited by a stop 97 that is adjusted by a micrometer 95. Small misalignment of the adjustment of the stop 97 and the setting of the lever 51 are compensated for by permitting the two parts 35, 36 to have limited movement against the spring 39 to an extent limited by the nut 38. Fig. 2. Specification 1078/03, [Class 102], is referred to.
