[Also in Division C5] The invention comprises (a) hydroxylated products of the general formula in which R is an unsubstituted or hydroxylsubstituted linear or branched hydrocarbon radical of 8-22 C atoms, optionally containing intermediate groups comprising hetero-atoms, X is -CH 2 OH or -CH 2 OCH 2 CHOHCH 2 OH and p and q are each less than or equal to 10 and (p + q) is at least equal to 1 but not greater than 10; and (b) intermediates of general formula where R, p and q are defined above and Y is -CH 2 Z (Z = halogen) or -CH 2 OCH 2 -CH = CH 2 . R is preferably a mixture of linear alkyl radicals of 9-13 C atoms or 13-18 C atoms, or -C 12 H 25 . The intermediates may be prepared by the addition polymerization of an α-diol of the formula R-CH(OH)CH 2 OH with glycerine epihalohydrin or alkyl glycidyl ether. An acid catalyst is preferably employed with the glycerine epihalohydrin, e.g. BF 3 , and an alkaline catalyst with the alkyl glycidyl ether, e.g. triethylamine. The hydroxylation of the intermediate from the alkyl glycidyl ether is carried out with an organic peracid formed in situ from H 2 O 2  and an organic acid, e.g. acetic or formic acid. In the case of the glycerine epihalohydrin-α-diol product the hydroxylation is effected with an alkali metal salt of a carboxylic acid. In Example (II) tetradecane- 1,2-diol, the starting material, was prepared by hydroxylation of tetradecene-1 then treated with glycerine epichlohydrin in the presence of BF 3 /acetic acid complex-catalyst. The product was hydroxylated using potassium acetate and the product obtained after ethanolysis has R = C 12 H 25 , X = -CH 2 OH, (p+q) having a statistical average value of 3À5. In Example (III) a product having R = -C 12 H 25 , X = -CH 2 OCH 2 CHOHCH 2 OH and (p+q) having a statistical average value of 1À75 was prepared from tetradecane-1,2-diol and alkyl glycidyl ether using a BF 3 -acetic acid complex catalyst and hydroxylating with performic acid.

Abstract: 1416566 Coated glass-fibre forming-apparatus OWENS-CORNING FIBERGLASS CORP 5 July 1973 [10 July 1972] 32151/73 Addition to 1287020 Heading B2E [Also in Division Cl] In a modification of the glass fibre-forming apparatus as claimed in claim 1 of British Patent Specification No 1287020 the refractory material is in addition bonded to the outer surfaces of the tubular projections except for the surfaces immediately adjacent and definining the orifices of the projections which surfaces are contacted by molten glass during use of the apparatus. The apparatus may be produced by roughening the entire bushing or bottom wall and tubular projections by grit blasting with pure alumina grit, then spraying the entire bushing or the bottom wall and tubular projections with a refractory material, preferably magnesium zirconate or a silicide, to produce a high density refractory coating and the ends of the tubular projections are then rubbed, for example with a soap stone to break up and remove any excess refractory material immediately adjacent the orifice of the tubular projections. Glass beads may be blasted at the back side of the tubular projections to remove any adherent coating from the inside thereof. The surfaces immediately adjacent the orifices are then ground and polished to obtain the desired contact angle of molten glass with the surfaces. The high density coating on a precious metal bushing also allows an external support for the bottom wall of the bushing to be used. The external support may be fabricated from a base metal also covered with a refractory coating or with a low emissivity coating such as platinum to effect the efficiency of the support as a heat-sink. As shown in Figure 3 a bushing 20 has a high density coating 22 on its exterior surfaces including the bottom wall and further on the tubular projections projecting outwardly therefrom as shown in Figure 4. Disposed about the coating on the side walls of the bushing except for the bottom wall and the projections is a high temperature fibrous material 24 to insulate and allow for expansion of the bushing during service and which facilitates removal of a disposable castable refractory material 26 if the bushing has completed its use in service. A relief 30 in the castable refractory material 26 is provided so that a terminal 32 connected to the bushing has sufficient room to receive an electrical connection to supply and maintain heat to the bushing for melting the glass therein. As shown in Figure 4 the bushing 40 has a high density coating 42 covering the bushing side walls 44 and the entire bottam surface 46 of the bushing including the base portions 48 and the side walls 50 of the tubular projections 52. The edges 54 are shown without the high density coating and possess a machine finish.

Driving.-Relates to mechanism as claimed in the parent Specification for rewinding the driving spring or springs of a gramophone or the like, by opening the lid of the casing, power being transmitted from the lid through one or more cords or cables. According to the invention, the cords are indirectly connected to the lid, through a lever or levers, or through gearing adapted to operate drums on which the cords are wound. Fig. 1 shows a construction in which two levers i (only one of which is shown) are fixed to the lid j and pass through the axis of the hinge. j<1>. To the outer end of each lever is connected a cord h, which passes over pulleys k and is wound over a shaft or drum d One end of a driving spring or springs is or are attached to the shaft or drum d, or to a drum or drums e secured thereto, the other end being attached to a fixed bracket f or the equivalent. The drive is transmitted to the turntable shaft a through a oneway clutch and gearing g. The arrangement is such that the cords h are drawn off the member d when the lid is raised, thus winding up the driving spring or springs. As the machine is driven, the cords are wound back upon the drum d. Tensioning means may be provided to keep the cords taut whilst the machine is working. A modification is described (Figs. 2 - - 5, not shown), in which the levers to which the cords are attached are not secured directly to the lid, but are pivoted to the back of the machine casing, the levers being connected to the lid by links. In this construction, the axis of the spring drum, and the drum or hollow shaft on which the cords are wound, are arranged vertically. Tension springs for counterbalancing the lid are connected by cords passing over pulleys to the operating levers. Fig. 6 shows a further modification, in which instead of levers being provided to operate the winding cords h, these pass from the drum d to a second drum d<1> having teeth with which quadrants w mounted on the lid j gear. The drum d<1> is thus rotated, when the lid is raised, to draw the cords on to it, and wind up tha driving spring; closing the lid reverses the rotation of the drum d<1> and allows the cords to hang loosely. A base weight, or a foot board, may be provided on the cabinet, to prevent tilting of the machine during rewinding.
