Alternatively, one side of the coated honeycomb 10, Fig. 13, may be inserted into liquid cement 48 which forms a cement facing when set. The other face may be similarly treated or provided with a facing of sheet material. In another form, the cells of the honeycomb may be entirely filled with cement 36, Fig. 11. Holes 50, Fig. 13, may be provided in the cell walls. Portland cement, gypsum plaster, Keene's cement, or a composition containing magnesite, sodium silicate, and calcium carbonate, may be used as the hydraulic cement.

Abstract: 611,541. Steam, &c. superheaters. BABCOCK & WILCOX. Ltd. March 27, 1946, No. 9469. Convention date, March 28, 1945. [Class 123(iii)] The temperature of superheated steam or other vapour being supplied to a turbine is regulated by passing it through a desuperheater into which is sprayed at a controlled rate an uncontaminated condensate of the steam or vapour, the latter being condensed at super-atmospheric pressure. As applied to a steam boiler 10, e.g. of the kind described in Specification 534,279, associated with a steam turbine 40, the desuperheater 34 is disposed between the two stages 32, 36 of the superheater, below economizer sections 24, 26 in the convection pass 14 of the boiler, and is supplied with condensate from a closed surface-type feedwater heater 57 through a pipe 70, pump 71 and pipe 47, the steam for the heater 57 being taken from between two stages of the turbine. Preferably the desuperheater 34 is of the type described in Specification 559,956 which is provided with a plurality of water-spray nozzles, and the supply of condensate thereto may be controlled automatically, in accordance with the boiler output and steam temperature, by a valve 46 in the pipe 47. The boiler is supplied with feed-water direct from the hot-well 50 of the turbine condenser 48 and through the condenser 54 of a steam jet air ejector, not shown, operated by steam from the main 38 supplied thereto by a pipe 53, to a pipe 56 having a make-up water supply branch 60, the water then passing in succession through the heater 57 and further heaters 62, 63, 64, each of which latter receives heating steam from selected extraction stages of the turbine 40, to the inlet pipe 22 of the economizer section 24. The heater 62 is of the direct contact type, and a high-pressure feed-pump 68 is fitted between this heater and the next heater 63, while the heaters 63, 64 are closed and the condensate therefrom is led to the heater 62, to augment the feed water, by a pump 65 and pipes 66, 67. A pipe 72, with automatic or manual valve 73, connects the outlet pipe of the pump 68 with the desuperheater water-supply pipe 47 so that spray water from the said pump may be used in an emergency.

Filed: 1945-04-17
Abstract: 590,302. Wave guides. WESTERN ELECTRIC CO., Inc. April 17, 1945, No. 9636. Convention date, April 28, 1944. [Class 40 (v)] In a wave guide transmission system, Fig. 1 shows a filter for removing TE waves from a mixed source 6 of TE and TM waves feeding a TM load 7 through a wave guide 8. The middle section of the wave guide is enlarged at 18 and is formed with radial slots 9 arranged 90 degrees apart. The slots are an odd number of quarter wavelengths deep and the openings 17 into the guide are about one wavelength long and one-sixteenth wavelength wide. Thus, only the TM waves which have no transverse current component are not attenuated by the slots 9 and pass to load 7. The slots 9 may be filled with dissipative material such as graphite held in a binder such' as plaster of paris. Fig. 3 shows a modification for removing from a mixed source 21 all waves having a longitudinal component of current, and feeding TE waves to a load 22. The filter comprises an annular quarter-wave slot 24 formed in enlarged section 23 so as to attenuate longitudinal currents. The width W of the slot is about one-sixteenth of a wavelength. The slot may be filled with dissipative material. The filters may also be applied to the outer conductor of a coaxial line.

Abstract: Foraminate nickel-aluminium catalysts which comprise particles of an alloy having robust cores and outer active layers resulting from partial or complete removal of the aluminium by the action of an extracting liquid such as acid or alkali, are used for hydrogenating benzene.  The particle size is preferably 1/8 -\ba1/4 inch. Catalysts described in Specification 570,843 are suitable.  For example, a 42 : 58 Ni : Al alloy is treated with caustic soda to remove about 20 per cent of the aluminium.  Catalysts prepared as in Specification 628,405 are preferred.  Specification 570,868 also is referred to.ALSO:Cyclohexane is produced by continuously reacting benzene in vapour phase with hydrogen at 100-200 DEG  C. and 1-5 atmos. gauge in presence of a foraminate nickel-aluminium catalyst. Said catalysts comprise particles of an alloy having robust cores and outer active layers resulting from partial or complete removal of the aluminium by the action of an extracting liquid such as acid or alkali.  The particle size is preferably 1/8 -\ba1/4 inch.  Catalysts described in Specification 570,843, [Group III], are suitable.  For example, a 42 : 58 Ni-Al alloy is treated with caustic soda to remove about 20 per cent of the aluminium. Catalysts prepared as in Specification 628,405, [Group III], by rapid cooling of Ni-Al alloys from the liquid phase, crushing and activating with alkali are preferred.  Peak temperatures are generally 170-200 DEG C., preferably 170-180 DEG  C.  Control is effected by use of reaction tubes jacketed by boiling water or other liquid or catalyst trays with intercoolers.  Mixtures of benzene with cyclohexane may be reacted.  Further zones at lower temperature may be provided beyond the zone at peak catalyst temperature.  Spare velocities of up to 1, preferably up to 0.4 l. of liquid/l./hr. are used.  At pressures around atmospheric, hydrogen in excess of stoichiometric proportions is preferred. Ammonia, nitrogen bases, sulphur and its compounds should not be present.  In an example, a 50/50 benzene, cyclohexane mixture is fed with a 5-fold excess of hydrogen at a space velocity of 0.3 over a foraminate Ni-Al catalyst at atmospheric pressure and up to 170 DEG  C.

Filed: 1986-05-08
Abstract: Peptides which inhibit the secretion of gonadotropins by the pituitary gland and inhibit the release of steroids by the gonads. Administration of an effective amount of such GnRH antagonists prevents ovulation of female mammalian eggs and/or the release of steroids by the gonads. These peptides may be used to treat steroid-dependent tumors, such as prostatic and mammary tumors. The peptides are cyclic analogs of the decapeptide GnRH wherein there is a covalent bond between the residue in the 4-position and the residue in the 10-position. Examples of such bonds include the disulfide linkage between Cys residues, an amide linkage between a side chain amino group and a side chain carboxyl group, a dicarba linkage between side-chain alkyl groups, and a carba linkage between a side-chain alkyl group and a side-chain sulfhydryl group.
