Abstract: 656,973. Springs. VRIES, A. DE, and  VRIES; L. DE.Jan. 20, 1949,No. 1665. Drawings to Specification. [Class 108(iii)] [Also in Group X] A slidingsash window is balanced by one or more tension springs which are so selected that the ratio between the increase in the force of the springor springs when stretched from the least-loaded conditionto the maximum-loadedcondition, andthe average force of the srping orsprings over this range is less than 65:100, the stretching range being equal or substantially equal to the length of the spring or springs when in the unloaded condition. The window may bebalaneed by two springs of unequal strength; the turning movement of the window in its own plane may be compensated for by friction members

Title: Improvements in and relating to apparatus for heat treating lengths of glass tubing
IPC: C03B29/02
Filed: 1942-02-13
Abstract: 554,347. Coating glass tubes. BRITISH THOMSON - HOUSTON CO., Ltd., and ABRAHAM, A. V. Feb. 13, 1942, No. 1960. [Class 56] Apparatus for heat-treating lengths of glass tubing, particularly for securing the attachment of a fluorescent coating to the interior of the tubes, comprises sets of rollers for supporting and rotating tubes while they are being heated and means for lifting each tube successively from one set of rollers to the next. The rollers 4, Fig. 1, are arranged parallel with one another, and all are rotated in the same direction and at the same speed by a motor 6. Gas burners 2 are arranged between and below some of the rollers, and those rollers adjacent to the burners preferably are of skeleton construction with helical or circular bands to limit the area of surface in contact with the glass tubes. In some cases the burners may be reciprocated longitudinally. The glass tubes 1 rest on and are rotated by pairs of rollers, and during the course of the heating each tube is moved from one pair of rollers to the next by fingers 25, Fig. 2, which extend downwards from a bar 9, each finger being moved in a rectangular path by cams on a motor-driven shaft 12. Another cam moves two sliding bridges into the free ends of each tube while it is in rotation on the rollers. One bridge carries a thermocouple, and the other carries nozzles which inject air or other gas into the tubes during heating. Each nozzle is provided with apertures 21, Fig. 3, to direct air along the tube, and with other apertures 20 which direct air towards the adjacent end of the tube to prevent burnt gas or other fumes from entering the tube.

A power supply network comprising a plurality of main power supply lines extending from a central power supply source has the power supply lines so arranged that each power supply line feeds the consumer apparatus in one of a number of main sectors of a notional circle centred on the power supply source, the boundaries of each main sector lying respectively in two sub-sectors in each of which the consumer apparatus has a small power requirement, the route of each power supply line being directed towards the centre of power of the respective sector such that the greater number of consumer apparatus are directly interconnected for the minimum length of the power supply line, the remaining consumer apparatus in a main sector being connected to the power supply line in the sector by additional power supply lines. The optimum amounts of divergence of the routes of the power supply lines from the straight line between the power supply source to the centre of power in each of the main sectors is calculated according to a formula given in the Specification and the centre of power in each main sector is also calculable by a formula set out in the Specification. Furthermore, when conditions are such that a relationship quoted in the specification is satisfied, consumer apparatus lying near the boundary of two adjacent main sectors may be cross connected. A financial benefit may be obtained by an interconnection between the power supply line in one main sector with that in an adjacent main sector. The network may be provided with Petersen coil earthing of neutral points and with excess current protection devices.

Abstract: 647,468. Power-generating systems ; turbine plant. MASCHINENFABRIK OERLIKON. Jan. 28, 1947, No. 2683. Convention date, April 18, 1946. [Classes 110(iii) and 122(iii)] Ship's auxiliaries are driven by the gas turbine 3 of a power generating plant which is separate from the main power generating plant and includes a combustion chamber 2 in which oil fuel is burnt with a large excess of air and the exhaust gases from the gas turbine are led to the ship's boilers 5 to aid combustion therein. Any additional air necessary to meet the difference between the quantity of unburnt air in the exhaust gases and the combustion air requirements for the boiler are supplied at 6 and may be pre-heated, whilst any surplus gas is tapped off at 7 and may be used to preheat the boiler feed water or the compressed air for the gas turbine unit. When the boilers are not in use but auxiliary power is required the gas turbine continues to operate as a separate unit and connections are arranged to enable the compressed air between compressor 1 and combustion chamber 2 to be heated by the exhaust gases from the turbine 3 in an existing boiler air preheater. Should the temperature of the turbine exhaust gases be too high for the boiler burners they may be cooled by heat transfer to either the boiler feed water or the compressed air of the gas turbine unit.
