Fluid flow apparatus for passage of through-flowline tools comprising two conduits having a common flow axis and adapted for limited longitudinal movement relative to each other while maintaining flow fluidtight communication therebetween provided with means for preventing the stopping of through-flowline tools within the conduits at any position of longitudinal movement. One embodiment comprises alternate longitudinal fingers and open end slots cut in the end of each conduit, the fingers of eac...

A method for fighting infestations by ants is disclosed. It consists in using 1-[(5-chloro-pent-4-inyl)-oxy]-4-phenoxy-benzene either as such or as an active ingredient of compositions or poisoned baits. The present invention concerns a method for fighting infestations by ants and, more particularly, it relates to a fighting method that consists in using, for the purpose, the compound 1-[(5-chloro-pent-4-inyl)-oxy]-4-phenoxy-benzene either as such or in the form of suitable formulations.

There is disclosed a method for fighting infestations of acari or noxious insects including ants, more particularly "fire-ants", by treating the insect, its habitat, or its food with a hydroquinone diether having at least one acetylenic and halogen-substituted chain and selected from 1-[(5-chloro-pent-4-inyl)-oxy]-4-phenoxybenzene of formula ##STR1## and 1,4-di-(5-chloro-4-pentinyloxy)-benzene of formula ##STR2## The disclosure comprises a method for fighting ants using the diether of formula (I...

There are disclosed 1-[4-(halophenoxy)phenoxy]-4-pentines of formula ##STR1## wherein R.sub.1 and R.sub.2 are each independently of the other chloro or fluoro and one of R.sub.1 and R.sub.2 is also hydrogen, a process for their preparation and intermediates for their preparation, the use of these compounds in pest control, and pesticidal compositions which contain a compound of formula I as active component. The preferred field of use is ovicidal control of pests.

Propynyl benzyl ethers having juvenile hormone-like activity which are 4-halogen, lower alkyl, lower alkoxy or propynyloxy substituted or 3,4-lower alkylenedioxy substituted and which can also be 3,5- and/or .alpha.-substituted, and insecticide compositions that include at least one propynyl benzyl ether and that can also include a conventional insect-poison.

A method of treating vascular thrombosis in warm-blooded animals, employing a phenoxyphenylacetylene or thio analogue thereof as the active antithrombotic agent.

Substances which are subject to microbial spoilage are preserved by addition of a dihydrocinnamyl phenol, e.g., dihydro-2-cinnamyl-phenol, dihydro-4-cinnamyl-phenol, dihydro-2-cinnamyl-4-methylphenol, etc.

Compounds having formula (I) wherein R.sub.1 and R.sub.2 are independently H or OH, are useful in the treatment and prevention of osteoporosis. The compounds of formula (I) are devoid of significant antiestrogenic and estrogenic activity. ##STR1##

The disclosure is of an antispasmodic pharmaceutical composition which comprises an effective amount of a compound of the general formula: ##STR1## wherein R is selected from the group consisting of the acyl radical of a carboxylic acid and hydrocarbyl; and a pharmaceutically acceptable carrier.

Polyene compounds represented by the formula ##STR1## in which R is H or an alkyl group of from 1 to 5 carbon atoms, R.sub.1 is H, lower alkyl of from 1 to 8 carbon atoms or aralkyl, and the pharmaceutically acceptable salts thereof. The foregoing compounds have been found active in regulating phospholipases and as such possess therapeutic value in the treatment of inflammatory conditions.
