Title: Improvements in or relating to leading-in insulators for high tension electric current
IPC: B03C3/70
Filed: 1938-11-29
Abstract: 521,974. Insulators. LODGE-COTTRELL, Ltd. (Siemens-Lurgi-Cottrell-Elektrofilter Ges. fur Forschung und Patentverwertung). Nov. 29, 1938, No. 34814. [Class 36] A lead-in insulator for the high-tension conductor of an electrofilter comprises solid and liquid insulation, the solid insulation projecting into the liquid insulation and being protected against contact with dirty gas by a sleeve which also projects into the liquid insulation. As shown in Fig. 1, a high-tension conductor 1 passing into an electrofilter b is supported by a solid insulator 3 mounted on and projecting into a chamber 7 carried by a wall 12 of the electrofilter. The cover of the chamber 7 is formed with an inwardly projecting sleeve 4 surrounding the inner portion of the insulator. The sleeve 4 and insulator 3 dip into insulating liquid 6 contained in a trough 5 carried by the conductor 1. The sleeve 4 prevents access of dirty gas to the inner portion of the insulator 3. The gas space of the chamber 7 is separated from the gas space of the electrofilter by a labyrinth 8, 10, 11 arranged in a lower chamber 9. The labyrinth may be so arranged as to hold a temporary liquid seal to prevent passage of gas into the chamber 7 when it is necessary to change the insulator 3 or the liquid 6. In the construction shown in Fig. 2 a high-tension conductor 13 is supported by a hollow cylindrical insulator 15 resting on the wall 21 of an electrofilter chamber, the lower portion of the insulator being submerged in insulating liquid 19, whilst its upper portion is protected from contact with dirty gas by a sleeve 16 dipping into the liquid. The insulator is spaced from the wall 21, and thus from condensate which may gather at the bottom of the liquid, by a ring 20. Fig. 3 shows a high-tension cable 26 passing into a socket 29 of a lead-in insulator 28 and connected therein to the high-tension conductor 35 of an electrofilter.

Title: Improvements in or relating to steroids
IPC: C12P33/00
Filed: 1953-12-16
Abstract: Cyclopentanophenanthrene compounds having a methylene group in the nucleus at the 11-position, e.g. cortical steroid type compounds having a methylene group at the 11-position, are 11b -hydroxylated by the action of oxygenating substances produced by growing a micro-organism of the species Curvularia pallescens or of the species Curvularia brachyspora.  The cyclopentanophenanthrene reactant may be subjected to the action of a growing culture of the micro-organism, or the micro-organism may be cultivated aerobically in a nutrient medium until substantial growth is obtained, the mycelium is separated from the broth and the cyclopentanophenanthrene reactant is then contacted with an aqueous suspension of the mycelium. Cyclopentanophenanthrene reactants may have a keto or hydroxy group at the 3-position, a hydroxy group at the 21-position and carbon-to-carbon double bonds in the nucleus, e.g. at the 3,4- or 5,6-position.  Specified reactants are desoxycorticosterone, progesterone, D 4-pregnene-17a -ol-3,20-dione, testosterone, D 4 - androstene - 3,17 - dione and D 1,43 - pregnadiene - 17a ,21 - diol - 3,20 - dione.  In the example compound F (17-hydroxycorticosterone) is prepared from compound S (17 - hydroxy - 11 - desoxycorticosterone) using Curvularia pallescens as the micro-organism in an aqueous nutrient medium.

Abstract: 487,782. Prepayment mechanism for meters. PEET, A., and ALDER & MACKAY, Ltd. Dec. 21, 1936, No. 35104. [Class 27] In order to render prepayment meter mechanism of the kind operable by coins of different values and having a separate striker for each measuring wheel, capable of being operated by the coins inserted through a single slot either indiscriminately at the consumer's option or by one of the coins for which the meter is set at the company's option, a pivoted arm 3, Fig. 1, is provided capable of being set to the right or across the path-of a latch 2 arranged between a coin-carrier and a detent carrier, whereby the latch selects the appropriate detent according to the value of the coin in the carrier. In the application to the coin-holder mechanism described in Specification 470,024, the arm 3 is held by a screw cr rivet 4 passing through an elongated slot 5 so that the arm may be moved longitudinally and angularly. In the position shown, the arm is set so that a penny or a shilling can be used at the consumer's option, a peg 10 on the arm engaging a hole 12 in the coin pocket 1. When the mechanism is to be set for use with a penny only, the arm 3 is moved downwards until the peg 10 enters a hole 13, a bevelled nose 6 on the arm then projecting into the path of the latch 2 which is provided with a rounded projection 7, Fig. 4. If a shilling is used in this setting, the latch 2 will dip and avoid contact with the shilling striker. When a shilling only is to be used, the arm 3 is rocked until the peg 10 enters a hole 11, thus bringing a curved portion 8 on the arm into the path of the latch and limiting the downward movement of the latter so that it cannot be operated by the insertion of a penny.

Title: Improvements in or relating to artificial resins
IPC: C08G8/28
Filed: 1935-12-20
Abstract: Oil-compatible hardenable resins are prepared by condensing with excess of formaldehyde substituted phenols, having only two reaction - favourable positions, in which the number of saturated carbon atoms is at least twice the number of phenolic hydroxyl groups and which contain at least one ethyl group in the molecule, the condensation being effected in the presence of strong alkalies, and, if desired, in the presence of solvents such as alcohol or benzene, at a low temperature and for a prolonged period.  Suitable phenols include o-and p-ethylphenol or condensation products thereof with carbonyl compounds in the presence of hydrochloric acid, polyvalent mononuclear phenols, mono- or polyvalent polynuclear phenols.  More than one ethyl group or other substituents such as methyl or chlorine radicals may be present.  Other phenols having only two reaction-favourable groups but not containing ethyl groups may be used in addition. The products may be blended by heating with fatty or drying oils, resins, resin esters or waxes and the blended products may be combined with oils.  In examples: (1) p-ethylphenol is condensed with aqueous formaldehyde in the presence of caustic soda and the product may be heated with chinawood oil, linseed oil or colophony glycerine ester, or heated alone and then with chinawood oil; (2) 1:2-diethyl4-hydroxybenzene is condensed with aqueous formaldehyde in the presence of caustic soda alcohol being subsequently added to keep the mixture homogeneous.  The Specification as open to inspection under Sect. 91 refers in general to the condensation of phenols which have only two free reaction-favourable positions per phenolic hydroxyl group and contain at least one ethyl group.  An example illustrates the condensation of a mixture of p-ethyl- and p-tertiary-butyl-phenol with aqueous formaldehyde in the presence of caustic soda.  This subject-matter does not appear in the Specification as accepted.
