A smoking tobacco product consists essentially of tobacco and a pharmacologically acceptable salt of an oxadiazole of the formula: wherein X is hydrogen, halogen or a lower alkyl group having from 1 to 4 carbon atoms, and R is an amino radical of the formula, (CH 2 ) nNR 1 R 2  wherein n is O or an integer of from 1 to 4 and Ri and R 2  are the same or different and are each either alkyl or alkylol having from 1 to 4 carbon atoms, the amount of the oxadiazole being sufficient to antagonise at least partially the ciliastic effect of tobacco smoke. Preferred acids for forming the salts with the oxidiazoles are citric, acetic, tartaric and gluconic acids. But mineral acids such as sulphuric, hydro- Chloric, hydrobromic or methanesulphonic acids may be used. The oxidiazole salt may be applied to the tobacco in either aqueous or organic solvent solution, the preferred solvents being methanol, ethanol and propanol. Oxadiazoles exemplified are 3- phenyl-5-diethylaminomethyl-1, 2, 4-oxadiazole; 3-phenyl-5-dimethylaminoethyl 1, 2, 4-oxadiazole; and 3-phenyl-5-ethylmethylaminoethyl 1, 2, 4-oxadiazole.

The cap additionally serves to prevent access of dust and moisture to the interior of the valve housing. The cap shown is pivotally mounted on a pin 42 engaging a vertical lost-motion slot 44 enabling the cap to move downwardly out of the opening before pivoting about the pin. The valve member 26 is guided by longitudinal ridges 31 on the internal surface of the housing and by stem and sleeve 28, 29. In an alternative embodiment, Figs. 4 to 6 (not shown), the cap is instead connected to the housing by a chain so that after dislodgement it is supported thereby. Moreover, the valve member stem is extended through the end wall of the housing to permit manual test operation of the valve.

Abstract: 1286870 Constant tension winches; transhipping at sea CANADA NATIONAL DEFENCE MINISTER OF 5 Dec 1969 59531/69 Headings B8B and B8E Apparatus for the transference of a load carriage 15 between relatively moving supply and receiving ships comprises a system for automatically maintaining constant tension in the transfer cable 7 and constant transfer velocity of the carriage 15. The latter rolls along a portion of the cable 7 extending between the tension winch 19 on the supply ship and a roller 11 on the receiving ship, the cable portion thereafter extending to the carriage 15, from which a further cable portion extends to the velocity winch 5 on the supply ship. The cable 7 extending from the tension winch 19 passes around a pneumatically powered cable accumulator 31 for absorbing sudden tension increases, and over a pulley 9 associated with a load cell 45. The latter generates a signal proportional to the cable tension which is electrically compared with a preset tension value and any resulting difference signal causes a variation in the output from an hydraulic pump 23 driving the hydraulic motor 21 of the winch 19 to maintain the cable tension constant. An alternative or additional arrangement for generating a cable tension signal for comparison comprises a tacho-generator 71, 73 associated with the drum of the winch 19 and the pulley 9, any cable velocity variation therebetween, due to the cable accumulation, action, being representative of tension variation in the cable. The drum of the velocity winch 5 is also driven from an hydraulic pump 103 having its output automatically variable under the control of a signal resulting from the comparison of a pre-set velocity signal and a signal derived from a tachogenerator on the velocity drum. In operation, the desired transfer velocity is set for the velocity winch, which velocity is automatically maintained whilst resulting variation in cable tension is compensated for the automatic tension control system.

Abstract: 1327599 Composite yarns HERCULES INC 30 Dec 1970 [15 Jan 1970] 61809/70 Headings D1F and D1W A method of preparing a composite yarn comprises plying a fibrillated uniaxially drawn film and a substantially twist-free staple fibre roving 5 and twisting the plied structure whereby the roving is ensheathed within the fibrillated film. A uniaxially drawn flat or striated film 1 is fed by rollers 3 to a rotating serrated bar 2 where it is fibrillated. The fibrillated film is then fed through rollers 4 together with a twist free staple fibre roving 5 and the plied structure is twisted at 6 and wound on a package 7. The twisted structure may be subjected to the action of a fluid jet to disintegrate the roving and entangle the staple fibres with the fibrillated film. In a preferred embodiment, the film may be only partially drawn prior to fibrillation, and the twisted structure is subjected to an additional drawing operation. The filaments of the fibrillated film may be stufferbox crimped, air jet bulked or if bicomponents of different shrinkage are used, they may be bulked by heat treatment. Several twisted structures may be twisted together to give a multiply yarn. The film can be formed of any known film-forming polymer, examples given being polypropylene, acrylics, polyamides and polyesters. The staple fibre roving may be of natural or synthetic materials e.g. cotton, wool, silk or any fibre-forming synthetic polymer either the same as or different from the polymer used in the film.

As shown, Fig. 1, sliders 10, 11 are moved outwardly along their respective guide rails 8, 9 in accordance with a horse total and the grand total of bets, respectively, so that the angular disposition of an arm 16 pivoted at 12 to slider 11 and biassed by a counterweight 17 to engage a shoe 15 pivoted at 14 to slider 10, is a measure of the odds on the horse in question. Rigid with the arm 16 is a radial wiper arm 24 carrying a contact 25 adapted to wipe over a transmitter potentiometer 27 mounted on the slider 11. The potentiometer 27 and a receiver potentiometer 28, Fig. 2, are connected in a Wheatstone bridge circuit fed with basic D.C. impulses. Unbalance of the bridge energizes a moving-coil relay 29, which, according to the sense of current flow therein energizes one or the other of stepping electromagnets 34, 35 to step the receiver arm 30 in the appropriate direction through ratchet mechanism until balance is again achieved. Indicators are moved synchronously with the receiver arm 30. An overload contact 49 is provided for the relay winding 29. Receiver construction, Fig. 3.

Associated with the rollers are brackets having yarn guide eyes 85 which brackets are secured to a bar 96 progressively influenced by a cam 99 to move the yarns from one end to the other of the rollers as knitting proceeds. The bar 99 also controls the Reeves pulley so that with variation in the rate of feed of the yarns through the feed rollers 73,74 the rate of rotation of the supply bobbins is also varied. Alternatively separate electric motors may be provided for driving the machine, rollers 73, 74 and roller 27 respectively, the motors for the rollers 73, 74 and roller 27 being influenced by the cam 99 to vary their speed. A lubricating device is positioned above the elastic yarns prior to their entering the rollers 73, 74 and feeds a lubricant on to them.
