Abstract: Abstract of the Disclosure A new class of 13-ethinyl-steroids is prepared by a novel process comprising Wittig  reaction of a 13-formyl steroid with a chloro- or bromomethylenephosphorane and dehydro-halogenation  of the intermediate 13-(2-halogenovinyl)steroid with an extremely strong base. Preferred products are those of the formula            or                 wherein R denotes a hydrogen atom or the methyl group, R3 denotes a hydrogen atom or a lower alkyl or lower alkanoyl group, R4 denotes a hydrogen atom or a lower aliphatic hyd-rocarbon radical, or R3 and R4 together denote a C-O linkage, R5 denotes the oxo group, a hydrogen atom together with an esterified or free hydroxyl group, or two hydrogen atoms, R6 denotes a hydrogen atom or a lower alkyl group, and R7 denotes a hydrogen atom or the methyl group, it also being possible for an additional 1,2-double bond to be present in compounds in which R is the methyl group. These compounds are pharmacologically active in a manner analogous to that of natural sexual hormones, and are distinguished as blockers of the secretion of pituitary gonadotrophins; accordingly, they are useful in  medicine for the corresponding indications and for fertility control.

Abstract: ABSTRACT OF THE DISCLOSURE             Gluing operations using cross-linkable vinyl acetate polymer emulsions have previously required the mixing of the emulsion with a catalyst.  The mix gels over a short period and cannot be used as a workable adhesive.  The foregoing difficulties are overcome by the present invention which provides a pre-mixed catalyzed adhesive composition comprised of an aqueous cross-linkable resin emulsion including a vinyl acetate terpolymer a hydrocolloid, an acidic metal salt cross-linking catalyst and an amine cross-linking inhibitor, the mole ratio of the inhibitor to catalyst being sufficient to at least increase the shelf life of the resin emulsion plus catalyst alone and to provide a cured water resistant bond.

Abstract: HOT WATER FLOOR HEATER          ABSTRACT OF THE DISCLOSURE       The heater is in the form of a hot water carrying pipe coil supported on a suitable base, such as a sub-floor, and having spaced parallel pipe ducts interconnected by pipe bends.  A pair of parallel supporting laths, preferably in the form of flat bars, are fixed on the sub-floor in spaced relation to the opposite side walls of a room to be heated, and circularly curved members are secured to the laths at spacings therealong equal to the spacing between the pipe ducts, the curved members on one lath being staggered longitudinally relative to the curved members on the other lath.  The connecting bends of the pipe coil are looped around these curved members, which latter thus serve as a pipe laying gauge.  Stop members are secured to the laths in spaced relation to the free ends of the curved members to form, in effect, troughs for the connecting pipe bends.  Heat trans-mitting metal lamellae are secured to the pipe ducts to intercon-nect adjacent pipe ducts, and these lamellae may be formed with half-shell portions at each end, one overlying a pipe duct and the other underlying the adjacent pipe duct.  The lamellae may be formed with alternating rows of depressions and elevations.          In hard to heat areas of the floor, the parallel pipe ducts may be arranged much closer together than in the remainder of the floor, as by having a pitch which is one half the pitch of the pipe ducts in the remainder of the floor and, in such case, the curved members in the hard to heat area of the floor have an angular extent of more than 180° and a radius which is less from that of the curved members in the remainder of the floor.  The lamellae may be metal or may be metal powder-containing plastic.

Abstract: ABSTRACT OF DISCLOSURE      A fluid control valve, principally for controlling the flow Or fuel to a compression ignition engine, comprises a valve body and a valve member slidable within the body, the valve member co-operating with a seating on the valve body to control the flow of fluid through the valve.  A spring urges the valve member into engagement with the seating and in use, the pressure of the fluid entering the valve is arranged to act on the valve member in opposition to the spring so as to lift the valve member off the seating.  The valve member and the seating are formed from electrically conductive material and are electrically insulated from each other except when the valve member is engaged with the seating.  An electrical terminal extends to the exterior of the valve body and enables the electrical resistance between the valve member and the seating to be measured.  The measured electrical resistance provides an indication of movement of the valve member towards and away from the seating.

Title: Method of manufacturing aromatic isocyanates
Inventor: MEYERS BERNARD A
IPC: C07C67/00
Filed: 1977-10-06
Granted: 1980-06-03
Abstract: ABSTRACT OF THE INVENTION           The reaction of aromatic amines with phosgene takes place in the mixing zone of a plug flow reactor to form both the product isocyanate as well as the intermediate carbamyl chloride. The aromatic amine dissolved in an inert diluent is fed to the center portion of the plug flow reactor while the phosgene is fed to the annular space. The reactor is designed so as to elimi-nate back-mixing at the feed zone and thus to avoid reaction of any in turn undesirable by-products such as urea and tar. Cold phosgene that is fed into the annular space cools the wall sufficiently to inhibit the reaction to PDI.  By heating the wall such as with the installation of a heating jacket to counteract the cooling effect of phosgene, the wall of the reactor is main-tained above 90°C. and  thus any solid carbamyl chloride that migrates to the wall is reacted to the isocyanate, eliminating pluggage of the reactor from solids build-up.
