[Class 112] 'Lubricating means for the bobbin-carrier raceway and loop-taker shaft are provided to prevent excessive friction and loss of oil. The bearing lug 4 of the bed plate 1 carries the looptaker shaft 6 in bushing 5 and has an oil well 12 closed by a ball valve 12a. The bushing 5 has an oil-distributing conduit 13 parallel with the shaft 6. This conduit lubricates the shaft bearing by ducts 13a, 13b. The conduit 13 and ducts 13a, 13b may be filled with wick to regulate the flow of lubricant. The conduit 13 is closed at its forward end by a wood plug 20 sufficiently porous to allow oil to seep through to lubricate the end wall of the hub 8a of the loop-taker. The shaft 6 is thus devoid of friction-producing devices such as packing glands. Oppositely inclined grooves 14a, 14b, 14c are formed in the shaft 6 to pick up oil adjacent to the ends of the bearing and impel it inwardly to prevent leakage. The inner end of the groove 14c terminates in a radial duct 15 communicating with an axial bore 16 in the shaft 6 and delivering lubricant to the bearing by a pumping action. Lubricant enters the duct 15 and flows through the bore 16 to be transmitted by a radial duct 17 in the loop taker to a duct 18 to lubricate the bobbin raceway.

In the tempering of a sheet of glass, particularly one to be used as a vehicle windscreen, a zone is cooled solely by radiation and the boundary between this " reserved " zone and the remainder of the sheet is sharply defined, the remainder of the sheet being more or less highly tempered by forced convection. Fragmentation originating in the tempered area is thus not transmitted to the " reserved " zone. Several forms of apparatus are described, that shown in Fig. 6 for example comprising, on each side of the sheet 1, a metal box 9- circular in vertical section-having cooling water inlet and outlet pipes 5. The surfaces facing the sheet are covered with a dull black diffusing coating, and aluminium foil " canalizers " 8<SP>1</SP> lead to the sheet. A circular " reserved " zone is thus formed and is separated from the remainder of the sheet which is tempered by forced convection from air-blowing boxes 3. The walls of the blowing chambers may be heated to lengthen the time of forced convection sufficiently to cover that necessary for cooling the reserved zone by radiation.
