Title: Process for the manufacture of isomeric dihydrofollicle hormones, analogues of the same containing less hydrogen, and their derivatives
IPC: C07J1/00
Filed: 1938-02-15
Abstract: 511,433. Sex hormones. SCHERING AKT.- GES: Feb. 15, 1938, No. 4742. Convention date, Feb. 16, 1937. Addition to 428,132. Samples furnished. [Class 2 (iii)] Follicle hormones and analogues thereof containing less hydrogen such as equilin or equilenin are reduced by enzymatic or phytochemical means. The process is an improvement in and modification of the method described in Specification 428,132. Suitable reduction methods are those described in Methoden der Fermente 1929, page 1212, and the preferred method is by means of yeast in the presence of sugar solution. It is stated that the process of the invention yields the highly active trans form of dihydrofollicle hormone. In an example an alcoholic solution of follicle hormone is allowed to drop slowly into a briskly fermenting solution of yeast and invert sugar. The fermentation is allowed to continue for about 90 hours, when the dihydrofollicle hormone is extracted and worked' up. Samples have been furnished under Sect. 2 (5) of products made in accordance with the present invention according to the following schedule :-(1) Oestrone acetate is introduced into an actively fermenting medium comprising an aqueous solution of invert sugar with sodium phosphate and yeast. The fermentation is allowed to proceed for 40-45 hours, when additional sugar and yeast is added. An ether extract is made, starting material is removed by semicarbazones, and the oestradiol is purified by crystallization from alcohol. (2) An alcoholic solution of oestrone acetate is added to an actively fermenting mass of cane sugar and bakers yeast. After two days further sugar and yeast are added and fermentation continued for 5 days. Unchanged starting material is removed by Girard Reagent. The oestradiol produced is crystallized from alcohol. (3) Oestrone propionate is treated and worked up as described in sample 2. (4) Oestrone n-butyrate is treated and worked up as in sample 2.

Abstract: 1,157,747. Methyl ethyl ketone; ethanol. CELANESE CORP. 1 Feb., 1967 [7 Feb., 1966], No. 4809/67. Heading C2C. Methyl ethyl ketone and ethanol are produced by blending water with a mixture of ethyl acetate and methyl ethyl ketone, heating the homogeneous blend in the presence of an acidic hydrolysis catalyst and separately recovering ethanol, produced by hydrolysis of ethyl acetate, and methyl ethyl ketone from the hydrolysis product. A fraction containing ethanol, ethyl acetate and methyl ethyl ketone suitable for hydrolysis by this process is obtained by subjecting a mixture of aliphatic hydrocarbons containing a substantial proportion of C 4  and C 5  hydrocarbons to partial oxidation in the liquid phase. Suitable acidic catalysts are acidic ion exchange resins, e.g. a sulphonated polystyrene ion exchange resin, and strong acids, e.g. sulphuric, phosphoric and arylsulphonic acids. The crude hydrolysis product is distilled to separate acetic acid as base product, the remaining fraction being redistilled to remove unhydrolysed ethyl acetate and methyl ethyl ketone is separated from ethanol in the residue by solvent extraction.

Abstract: 697,455. Hollow-ware; boxes. FISHER & LUDLOW, Ltd. Feb. 16, 1951 [Feb. 25, 1950], No. 4897/50. Classes 18 and 66 [Also in Group XXX] Foot elements for use with a metal container 10 comprise an upper attachment portion 17 secured to the container adjacent the bottom at positions spaced around the periphery, an abutment portion 16 connected rigidly to each attachment portion and adapted to rest on the top of a second similar container and to transmit the superposed load thereto, the abutment portion being spaced below the level of the attachment portion so as to permit of the insertion of the arms of a fork truck between any two containers of a stack, or beneath a single container or beneath the lowest container in a stack. A locating portion is connected rigidly to the abutment portion of each foot depending below the abutment portion and shaped to engage with the exterior of a side wall of a second similar container therebeneath and adjacent the top thereof without extending into a recess or opening in the top. When the foot elements are in situ, the container on which they are provided is thereby located against lateral movement in relation to the container immediately beneath, and each of the locating portions further adapted to engage with the floor or other external support. As shown in Fig. 3 the lower abutment portion 16 is formed as a sheet metal member of angle section and of right angle form viewed in plan, and comprises an upper horizontal abutment flange 18 which forms the abutment portion proper, and a dependent outwardly inclined locating portion formed as a flange 19, the attachment portion being formed separately from the abutment portion and being also of sheet metal of right angle form viewed in plan. This comprises an upper horizontal attachment flange 20 and a depending spacing flange 21, the lower edge 22 of which is welded to the upper face of the abutment flange 18 to secure the two portions of the foot together. For circular containers a similar element circular in configuration is used. In a modification shown in Fig. 4 the abutment and attachment portions 16, 17 may be integral by forming the spacing flange 21 as an integral extension of the abutment flange 18. In another modification shown in Fig. 6 the abutment portion is of the same construction as Fig. 3 but the attachment portion is further provided with a bracing member 23 in the form of a metal plate which extends between the outer ends of the attachment flange, the depth of the bracing plate 23 being greater than that of the spacing flange 21 by the thickness of the abutment flange 18 so that the lower edge of the bracing plate lies flush with the under surface of the flange 18. The end portions 24 of the bracing plate 23 are bent so as to lie against the ends of the spacing flange and attachment flange at which position the bracing member is welded to these flanges.

Abstract: 868,161. Closures for resisting fluid pressure. BIRFIELD ENGINEERING Ltd. Feb. 16, 1960 [Feb. 16, 1959], No. 5240/59. Class 123(1) [Also in Group XXVIII] Sealing means for an opening, e.g. the upper end of a standpipe, comprises a cup-shaped, flexible sealing member 9 the side wall 9a of which is adapted to seal against the wall of the opening, pressure means 12, abutment means 1 adapted to be fixed relatively to the opening, and wedge means 6 surrounded by the pressure means. Movement of the wedge means outwardly of the opening urges the pressure means laterally outwards to press the member 9 into sealing engagement with the wall of the opening, movement of the pressure means with the wedge means being limited by the abutment means. Positive pressure within the opening may act to produce or assist the sealing engagement. As shown, the member 9 is clamped to the annular wedge member 6 which is carried on a hollow stem 5, and the conical wedging surface 10 of the member 6 is held in contact with the inclined inner surfaces of an annular ring of segmental pressure shoes by an annular spring 13 seating in a groove 15 formed in the shoes. The spring has an internal wire 14 which holds the shoes together in the event of breakage of the spring, and the shoes are provided with spaced lands 20 the innermost land 22 of which projects slightly in a lateral direction. In sealing the opening the closure plug is locked in the opening by cams 3 engaging in a recess 4 in the pipe 2 and the stem 5 is moved outwardly so that the shoes 12 engage the abutment ring 1, further movement of the stem causing a wedging reaction between the ring and shoes to urge the latter outwardly so that the land 22 of the shoes press a localised continuous area of the wall 9a of the sealing member into sealing engagement with the wall of the opening; as wedging action continues the remaining lands 20 in turn press against the wall 9a so that the sealing area progressively increases. The member 9 is ridged at 23 to facilitate flexing thereof. The pressure ring may be continuous and sufficiently flexible to undergo the requisite expansion and is preferably of split form, or a number of split rings may be arranged side-byside in an axial sense; the ring or rings may be mounted on a split ring carrier expanded by the wedge means.

Title: Improvements in and relating to the shaping of clay-ware articles
IPC: B28B1/02
Filed: 1949-02-28
Abstract: 676,428. Shaping clay ware articles. GREEN & CO., Ltd., T. G., SMITH, H. J., JOHNSON, J. A., and HAWK, E. A. Feb. 22, 1950 [Feb. 28, 1949], No. 5325/49. Class 87 (ii) Flat clay-ware articles 22 are shaped by means of a roller tool 25 of the same contour as the article, the driving mechanism of the tool or the article holder 20 being arranged so that there is relative rotary movement between the tool and the contacted surface of article during the whole of or part of the shaping operation. The rim of the article is trimmed by a scraper 23. Both the components 20, 25 may be positively driven or one of them may rotate freely. The relative rotary movement is created by slowing down, stopping or reversing one of the components. As shown, the tool 25, universally adjustable upon rotating head 27, is driven by a motor 32. The roller and its drive are pivoted at 34 and they are rocked about this pivot into and cut of the operative position by means of a link 38 connected to an arm carrying a roller 39 which rides on a cam 40 on a control shaft 41. The holder 20, is driven through a clutch 70 of the type described in Specification 574,920, [Group XXIV]. The clutch is engaged by slightly tilting the motor 11, the tilting movement being controlled through a scroll cam (not shown) on the control shaft 41. The control shaft 41 carries another cam (not shown) which towards the end of the shaping operation operates a brake 57 on the roller 25. Before the brake is applied, another cam 63 on the same shaft acts to switch off current to the motor 32. After a prescribed interval the cams disengage the brake and switch on the motor. Instead of braking the roller 25, the holder 20 may be braked, or one of these components may be accelerated with relation to the other. An electric, magnetic or hydraulic brake can be used. The components may be rotated at different speeds throughout the shaping operation. The shaping tool 25 may rotate bodily around the holder 20 about its axis and this movement may be submitted to the various braking and accelerating controls referred to above. Specifications 621,712 and 657,544 also are referred to.
