Title: Improvements in or relating to the manufacture of brushes or brooms
IPC: A46B9/02
Filed: 1921-06-09
Abstract: 190,430. Barnett, C., and Barnett, W. June 9, 1921. Bristles, fixing; brush-making machines.-In the manufacture of tufts or knots of bristles for sweeping-brooms one end of a bunch of undoubled bristles is treated with pitch or like cementing substance and bound by a metal ferrule initially of such a character that upon being annularlv compressed it is irregularly crimped to hold the bristles and to form a jagged exterior surface which assists in holding the finished knot in the broom-stock. The tuft may be formed by applying a corrugated tapering ferrule B, Fig. 3, to the cemented end of a bunch of bristles A and subjecting the ferrule to two compressing operations, one for crushing the ferrule to cylindrical form the other for crushing the ferrule to produce an irregular surface, as shown in Fig. 6. Other forms of ferrule which may be employed include a cylindrical corrugated ferrule and a conical ferrule which is not corrugated. Specifications 162,056 and 190,180 are referred to. According to the Provisional Specification, the ferrules may be stamped from sheetmetal bands by a press forming part of a machine for manufacturing the finished tufts, in which case the tufts are dipped in pitch before the ferrules are applied. Alternatively, the ferrules may be made from a separate machine and threaded over the tufts, the pitch being thereafter applied and the ferrules finally drawn back over the pitched ends.
Patent GB-683900-A (GB)
Title: Preparation of unsaturateed acids and esters of the steroid and polyhydrophenanthrene series
IPC: C07J3/00
Filed: 1949-12-14
Abstract: Unsaturated acids of the general formula <FORM:0683900/IV (b)/1> (wherein R represents a bivalent steroid residue, including a steroid residue without a cyclopentano ring), and their ethyl esters, are manufactured by condensing a ketone of the general formula <FORM:0683900/IV (b)/2> (especially a 17-ketosteroid of the androstane or aetiocholane series) with a Grignard reagent prepared from ethoxyacetylene to form an ethoxyacetylenyl alcohol, treating this with acid to bring about rearrangement to the ethyl ester of the unsaturated acid, and, if desired, hydrolysing this to the free acid. The treatment with acid (preferably a dilute mineral acid) may be effected by dissolving the acetylenyl alcohol in a water-miscible solvent and acidifying or by dissolving it in a water-immiscible solvent and shaking the solution with a dilute acid, the rearrangement in either case being advantageously facilitated by warming.  The ester may be isolated by pouring the reaction product into water and collecting the precipitate, or by shaking the reaction product with a solvent for the ester.  When the residue R contains one or more hydroxyl groups, this group or groups may be protected by acetylation prior to the reaction with the Grignard compound.  In examples: (1) 17(a )-ethoxyacetylenyl - D  5 - androsten - 3(b ) : 17(b ) - diol - 3 - acetate, obtained by condensing dehydroandrosterone acetate with ethoxyethynyl magnesium bromide, is dissolved in ethanol, acidified with dilute sulphuric acid and allowed to stand, and the resulting ester is isolated and hydrolysed to 3(b )-acetoxy- D  5 : 17 - pregnadienoic-21-acid; (2) epiandrosterone acetate is reacted with ethoxyethynyl magnesium bromide in ether, and the resulting 3(b ) : 17(b )-dihydroxy-17(a ) - ethoxyacetylenylandrostane - 3 - acetate is treated as in (1) to produce 3(b )-hydroxy-D  17-allopregnenoic-21-acid.  Formul  are given of additional starting materials, including 1-keto-7-hydroxy - 2 : 13 - dimethyl - D  9;14 - dodecahydrophenanthrene.

Title: Electric continuous flow liquid-heater
IPC: F24H1/10
Filed: 1960-09-20
Abstract: 943,027. Electric continuous-flow water heaters. A. ECKERFELD. Sept. 20, 1960 [Sept. 29, 1959], No. 32245/60. Addition to 905,123. Heading H5H. A continuous-flow water heater as described in the parent Specification, is modified in that the base body, instead of being fixed to a separate back wall, itself forms the back wall of the apparatus and supports a cover for the apparatus. The apparatus is shown with the cover removed from the base body 1 of insulating material which has an inlet socket 2 and two discharge sockets 3 and 4 at its lower side and also supports the other components of the apparatus. Two diaphragm switches 6 and 7 respond to a pressure difference on flow of water through the apparatus and actuate electric switches 8 and 9 through bell-cranks. Two attachment bodies 12 and 13 each comprise three communicating heating channels containing coiled filaments and a diaphragm switch connected to a safety switch. Electric terminals T are mounted on the lower portion of the body 1. An inlet channel 18 leads from socket 2 to a hole 19 communicating with an over-pressure chamber of the diaphragm switch 6. A transverse channel 21 leads from hole 19 to a corresponding hole communicating with an over-pressure chamber of diaphragm switch 7 and with a channel 24 which communicates with two of the heating channels of each attachment body 12 and 13. The third heating channel of body 13 is connected to a channel 26 leading to the top of the apparatus where it communicates with a low-pressure chamber of diaphragm switch 7 and then back to discharge socket 4. The third heating channel of body 12 is connected by a channel 28 to discharge socket 3 and communicates with a low-pressure chamber of diaphragm switch 6 via a connecting pipe 30. The filaments of body 13 are energized by switch 9 as soon as water flows through the body 13 and channel 26 to discharge socket 4 to operate diaphragm switch 7. Similarly the filaments of body 12 are energized by switch 8 when water flows through body 12 and channel 28 to discharge socket 3 to operate diaphragm switch 6. The operating contact of each switch 8 or 9 is however connected in series with an open contact of the other switch so that not all the filaments of the apparatus can be in operation at the same time, thus preventing overloading. The safety switch is normally locked in its closed position, but is opened by either of the diaphragm switches in the bodies 12 or 13 if the pressure in the heating channels suddenly rises owing to the formation of vapour, and can then be reset manually.
