In a gas-fired space and water heater having water chambers 13, 14 contained within a combustion chamber 1, the space and water heaters have independently operated gas burners 11 and 12 respectively. The chamber 1'3 is spaced from the chamber 14 and from the front wall 2 of the combustion chamber to define flue ducts 27, 26 respectively. In operation, the combustion gases from the burner 11 pass upwardly over incandescent mantles 6, through the duct 26 and into the upper part 1<SP>1</SP> of the combustion chamber to exit via an aperture 30 to a housing 31 provided with a deflector plate 38 and thence to a flue 37. Combustion gases from the burner 12 pass upwardly through the duct 27, heating the water in the chambers 13, 14 and then exit as described to the flue 37. V-shaped deflectors 28, 29 are placed above the respective ducts 26, 27. The chambers 13, 14 extend between header chambers (18, 19, Fig. 2, not shown) which are connected into a radiator heating circuit via inlet and outlet connections 25, 24.

Yarn (or a drafted bundle of fibres from which yarn is manufactured by conventional processing including further drafting) capable of being bulked, as a result of differential shrinkage of fibres, on its subjection to heat in the absence of tension in the yarn, is produced by passing through a roller drafting frame e.g. a draw, slubbing, intermediate, roving or ring-spinning frame, at least one fibre bundle e.g. a carded or gilled product such as sliver, slubbing or roving, incorporating at least 5% (preferably 20%) by weight of staple fibres which are stretchable when heated and which have lengths greater than the reach between adjacent pairs of drafting rollers, heating the bundle before or during its passage between the adjacent pairs of rollers so that the fibres are stretched (preferably to a maximum short of breaking) whilst the bundle is drafted, and cooling the bundle whilst it is tensioned. Heat-stretchable fibres may be of polyamide, polyacrylonitrile, polyolefin, polyvinylchloride The bundle may contain inextensible fibres of greater length which break during drafting. Heat may be applied by infrared radiation, contact with a heated plate or plates and/or heated fluid such as steam.

Abstract: 1,229,361. Injection-blow moulding; transfer mechanism. BLEWIS & SHAW (PLASTICS) Ltd. 25 Aug., 1969, No. 42239/69. Heading B5A. In an injection-blow moulding machine, the transfer mechanism comprises a transporting member TM to which the parison stick 5 may be connected, carriage means 14, 15 and a support structure SS alsong which the carriage means may be traversed from the injection mould to a blow mould. In the embodiment illustrated, the parison stick 5 is connected to the transporting member TM by clips 10 and pegs 22, the carriage means comprising block 15 housing shafts 14 on which are mounted rollers RB. The carriage means are moved along between plate TP, and plate 26 of the support structure by rack-driven fingers F engaging spigots 42, 43 on the transporting member TM and parison stick holder, respectively. During this movement, lug 55 on the parison stick holder slides into recess 54 on hydraulically actuated head 53 which retracts to disengage the parison stick holders from the transporting member TM to place the parison sticks in the respective mould. The apparatus also comprises an injection mould IM located between a pair of blow-moulds BM1, BM2, each mould comprising a fixed part 1 and a movable part 3. The ejector means comprises a set of fingers which when raised pass between the parison sticks, above the level of the article, when these are removed from the blow-moulds and which then descend to remove the article. Air is supplied at each blow-mould through air lines AL having terminal connectors 59 engaging with inlet nozzles 60 on the parison stick holders. Each movement of the apparatus may be effected automatically at the termination of the preceding movement by a series of limit switches controlling the valves of the hydraulic circuitry &c. From the position when all the moulds are closed, the left blow mould, BM1, is opened, the left ejector raised, the articles on the parison sticks are pushed from this mould by extension of head 53 and the ejector lowered to strip the articles. The injection mould is opened and the parison sticks pushed therefrom to engage the transporting members. The racks are then actuated to interchange these parison sticks and the injection- and left blow-moulded BM1 closed. The right blow mould, BM2, then opens and the articles are ejected as above, and, after opening the injection mould, these parison sticks are interchanged and the moulds closed thereon. The supporting structure has a passing loop (Fig. 4, not shown) for the carriage means and the carriage means is halted in position by retractable stops (CS1, CS2, Figs. 2, 3, not shown) either side of the injection mould and fixed stops (RHS, LHS) at the outer extremities of the blow moulds.

[Also in Division E1] Test cores are obtained from, e.g. cast-in-situ concrete floors, by employing a two-part mould, comprising an outer frusto-conical member A and an inner cylindrical member B which may be integral with, or separate from the outer member. When the mould is in two parts, the member A, together with the concrete inside it, member B, and the concrete therewithin, are all removed together from the in-situ mass, or alternatively everything inside member A is so removed, and thereafter the core is removed from this body, in the member B, either by driving it out, or chipping away the surrounding concrete. The core is thereafter driven out of member B. With a one-piece mould, the core is driven straight out of the mould after it has been removed from the in-situ mass. A separate inner member B may be supported on a block, or an inner, vertical peripheral wall on member A with an integral or separate partition across the top.
