Abstract: 1,267,200. Fire extinguishing in enclosed spaces. C. B. DAVIS. 29 Sept., 1969 [2 Oct., 1968], No. 46782/68. Heading ASA. A method of extinguishing fire within a substantially enclosed area comprises circulating the hot air and combustion products within said area through an open-ended passageway therein by projecting a fluid into said passageway from a point between its ends in a direction toward and out of one end thereof and entraining with said fluid a fire extinguishing agent which neutralises the effect of the circulating hot air and matter. The fire-fighting apparatus comprises central open-ended tube 1 formed with annular flange 3 around which is mounted upper annular body 4. Lower annular body 9 surrounding the central part of tube 1 threadedly engages with body 4. Annular recess 13 in 9 co-operates with passageway 7 in 4 in which is secured pressure line 8, and annular passageway 16 is defined between body 9 and tube 1, and is adjustable in size by means of washers between facing surfaces of flanges 14, 17. Collar 25 on 4 is rigid with perforated circular plate 26, collar 27 surrounds and is rigid with the outer edges of 26. Collar 18, threaded on 9, supports perforate cylinder 29 which in turn is secured to imperforate circular bottom plate 30. Ring 21 supports perforate cylinder 33, which with cyinder 29 forms chamber 35. Perforate cylinder 36 and imperforate cylinder 37 define chambers 40, 43, slanted wall 38 of 37 also being imperforate. Concave shield 44 deflects and guides smoke and combustion products to the upper open ends of tube I and chambers 35, 40, 43. 43 contains fire extinguishing powder, which is protected by imperforate cylinder 46 and top wall 47 of heat fusible material, e.g. Pb, Pb alloy or foil. 35 and 40 contain steel turnings 48 to provide tortuous passages for the flow of fluid. A fire extinguishing agent is supplied down lines 8 and ejected into tube 1 via passages 16. The agent may be CO 2 , exhaust gas from an internal combustion engine, or other gas, liquid or solid, and may be supplied to pressure chamber 13 at a pressure of 1500 lbs./sq. in. In operation, lines 8 are opened manually or automatically and a jet of extinguishant is projected through cylinder 33, causing suction at the upper end of 1 to draw in smoke and heated air. The hot gases pass through chambers 43, 40 and 35 and into the stream of extinguishant, while powder in 43 is drawn successively through 40 and 35 where it is trapped by the turnings and generates CO 2  to mix with the extinguishant jet. The cyling of gas or fluid within the enclosed area is said to quickly render them non-flammable.

Abstract: 1290422 Rupturable packages W S SCHNEIDER 26 Aug 1970 [8 Sept 1969] 40949/70 Heading B8C A package has two laminated walls sealed together to define a product holding space, one of the seals extending across a release area 26 in which the bond between the inner and outer layers 10a, 10b of the laminated wall 30 is weakened so as to enable the inner layer 10a to be ruptured to open the product holding space. The release area 26 is formed by a layer 27 of a graphite base ink, a silicone compound, or grease, interposed between the layers 10a, 10b, when the laminate is made. The package may have two compartments separated by a transverse seal 20 which extends through the release area 26 and has a triangular portion 36 to concentrate stress on the release portion 26 when the inner layer 10a is to be ruptured, e.g. by pressure exerted on one compartment which may contain a liquid to be mixed with a powder in the other compartment. A portion 38 of the inner layer 10a within the release area is thinner than the remainder to facilitate completion of the rupturing. The package may be made from a longitudinally folded web or two opposed webs, the web material being a laminate of cellulose acetate or a polyester with heat sealable polythene, or vinyl or rubber hydrochloride. Alternatively, adhesive may be used to seal the package. In the apparatus of Fig. 6 a web 10 is folded into a tube about a mandrel 12 and is longitudinally sealed by sealing heads 14. Further sealing heads 18 then form a transverse seal 20 at a portion of the web not containing a release area. A substance is then fed into the tube and a further transverse seal 20 is formed across a release area 26 and above the substance. A second substance is then fed into the tube which is then sealed to form a package which is severed from the tube by cutters (22, Fig. 7). One substance is fed through the mandrel 72 and the other through a tube 19 within the mandrel.

Abstract: 1296981 Polyurethane foams E I DU PONT DE NEMOURS & CO 12 Dec 1969 [29 Jan 1969] 4997/69 Headings C3C and C3R Flexible polyurethane foams are prepared by reacting an unrefined primary diamine phosgenation product having an amine equivalent of 87 to 168 with a polymeric diol or triol or mixture thereof having an average M.W. of 3000 to below 7000, in the presence of a non- polymeric polyol as a cross-linker, a blowing agent and a catalyst but in the substantial absence (defined) of a silicone stabilizer which is a polyoxyalkyleneether-polydimethyl-siloxane block copolymer. By the term " substantial absence " is meant the total absence of said stabilizer or the presence of such an amount as not to detract substantially from the inherent flame retardant and sag factor characteristics of the foam. The phosgenation product is most suitably that obtained by phosgenating a mixture of toluene-2,4- and -2,6-diamines. Suitable polymeric polyols have a M.W. of 4500 to 6000 and are polyalkylene ether diols or triols. The non-polymeric polyol preferably contains 2 to 8 OH groups and is alicyclic, aromatic or aliphatic. Conventional blowing agents, tertiary amine and organo-tin catalysts and stabilizers (subject to the above limitation) may be included in the reaction mixture.

Abstract: 1302408 Record player KATSUMI WATANABE 5 Feb 1970 5463/70 Heading G5R In a record player for mounting in a toy and operated by an electric motor, increased pressure is applied to the pick up as it tracks inwardly of the record to maintain record speed constant. Turntable 21, supporting record 2, is belt driven by motor 1 and pivotably mounted on a base 20 which can be hinged downwardly to allow record change. The record is held by retaining member 25 and an extension 26 of the turntable pivot closes a pair of contacts 36, 37 in the motor supply circuit when the base is in its closed position. Pressure bar 3 is loosely mounted at its middle on the apex of speaker 10 and bears down at one end 4 on pick-up arm 5. At its other end 6 the bar is forced upwardly by spring 8 so that as the pick-up arm tracks inwardly the pressure exerted thereon by the arm which pivots at its point of attachment to the speaker, increases and the load on the motor drive stays approximately constant. When the pick-up arm reaches its inner position it moves contact 17 from fixed contact 18 and thus opens the motor drive circuit. To replay the record, rod 15 is manually depressed momentarily pivoting the bar 3 upwards out of contact with the pick-up arm which is spring loaded upwardly and outwardly; the movement of the arm to its start position allows contacts 17, 18 to re-engage to drive the motor.

Arm 7 may be articulated as shown in Fig. 2 so that it can fold flat on mirror 1 or as shown in Fig.13 with a spring forming a section 9. Alternatively a spring may form the outer section of arm 7, Fig. 12 (not shown), a make-up member fitting into the end of the spring. Different make-up members can be fitted to the arm by using an attachment 22 which has a square hole 23 for fitting to arm 7 and a round hole 24 for the acceptance of a make-up member. A plug 25 can fit in hole 24 to adapt the attachment so that it is suitable, for example, for a lip brush. The mirror 1 is mounted on a support member 2 where it is retained by projections, 3, 4 and 5. A back plate 21 is slidingly attached to the support member so that the device may be adjustably steadied against the bust of a user. The plate has projecting arms 33, 34 connected by a strap 35 the ends of which being inclined so as to ride over projections 32 but can abut against the projections when the plate is pushed towards its inner position. The mirror may be removed from the support plate and engaged in slots (27) Fig. 4 (not shown) therein so that the device may form a free standing mirror, Fig. 11 (not shown).
