Title: Improvements in signalling devices
IPC: E01F9/619
Filed: 1924-09-03
Abstract: 243,797. Gas Accumulator Co. (United Kingdom), Ltd., (Svenska Aktiebolaget Gas Accumulator). Sept. 3, 1924. Signs.-A reflecting sign or signal for use at cross-roads or for similar purposes of the kind adapted to return an incident beam to its source comprises surfaces arranged mutually at right-angles either to form a solid triangular pyramid, in which the rays undergo both reflection and refraction, or as mirrors to form a solid angle in which the rays undergo reflection only, in combination with means for diffusing the incident or reflected rays so as to increase the angle within which the signal is rendered visible. In one arrangement, the signalling device comprises a series of tetrahedra 5, Fig. 1, arranged at the rear of and preferably formed integral with a sheet of glass 4, and is mounted on the top of a standard 1 within a solid metal backing 2 provided at the front with protecting bars 10. A reflecting coating of mercury or other suitable material may be applied to the rear face of the device The means for diffusing the light may consist in providing one or more of the reflecting surfaces with lens-shaped projections or facets, or in roughening the surfaces, or in inserting a roughened piece of glass in front of the device. Fig. 7 shows a modification in which the reflecting surfaces are formed by mirrors 30, 31, 32. In any of the constructions the return beam may be coloured as desired 'by the use of coloured glass in making the pyramids or by the interposition of a sheet of coloured glass in the path of the rays. Reference has been directed by the Comptroller to Specifications 21856/03, [Class 118, Signalling &c.]; 148,939; 194,064, [Class 97 (i), Optical systems &c.]; 201,982, and 233,002.

Title: Improved spinning process and apparatus for carrying out such process
IPC: C03B37/00
Filed: 1958-07-01
Abstract: 846,624. Weight controlled glass spinning processes. AMERICAN AIR FILTER CO. Inc. July 1, 1958 [July 25, 1957], No. 20999/58. Class 56. In a glass spinning process in which molten material is fed from a furnace transversely reciprocated axially above a rotating drum on to the drum to form a solid cylindrical filamentous layer thereon, the initial weight of the furnace and its contents is measured at the beginning of the spinning operation and the furnace is replenished during spinning to approximately maintain this initial weight. This control may be effected by mounting a balance weight scale 20 on the traversing furnace carriage 10 and suspending the glass furnace 26 and the feeding funnel 28 from the weight sensitive plate 22 of the scale. By this arrangement the furnace and contents are continuously balance weighable during spinning and any loss of molten glass from the furnace is indicated by displacement of the balance arm in superstructure 24. After a predetermined loss (e.g. 1, 1b.) of molten glass the furnace may be recharged to its original weight. The process may be repeated until the charging glass available (e.g. 21 1bs.) is exhausted. A constant rate of spinning may be achieved by controlling the furnace temperature so that the time interval between recharges remains constant.

Abstract: 920,473. Axial-flow fans. C. SCHULERVOITH, M. VOITH, H. W. SCHWEPPENHAUSER, and C. KNAPP, [trading as VOITHGETRIEBE KOMM. GES.]. June 13, 1961 [June 25, 1960; Oct. 29, 1960], No. 21337/61. Class 110 (1). [Also in Groups XXIV, XXVII and XXIX] A fan 5, Fig. 1, is driven through an hydraulic power transmission comprising an hydrostatic pump 3 coupled to an hydrostatic motor 4, and an arrangement which allows the output shaft of the transmission to run faster in the normal direction of rotation than the speed which corresponds to the reigning speed of operation of the input shaft of the system. The pump may be driven by belts 2 from the engine 1 of a locomotive and supplies fluid through a line 8 connected to the motor 4 which drives the fan 5 disposed adjacent a radiator 6 for the cooling system of the engine. In the event of the engine 1 slowing as a result of the locomotive climbing a gradient or halting, the inertia of the fan drives the motor 4 as a pump, vacuum in the line 8 which would slow the motor being prevented by fluid being drawn into the line 8 by the motor through a line 16 and a one-way valve 17 in a reservoir 7 receiving fluid discharged from the motor through a line 9. The pump can be tilted to vary its output by a unit 15 controlled by a temperature-responsive element 13 in the cooling system. The degree of the opening of the valve 17 is varied by links 18 connected to the pump and to a sleeve so that the amount of overrunning of the fan is controlled in accordance with the temperature of the cooling system. In another embodiment, a one-way valve 17<SP>1</SP> is disposed in a line 16<SP>1</SP> between the lines 8, 9. In a further embodiment, the motor 104, Fig. 3, is connected by a freewheel coupling 133 to the fan 105 to permit the fan to overrun the motor. A friction clutch 135, 136 is arranged in parallel with the coupling and is disengaged by fluid pressure from the unit 115 which is actuated by the temperatureresponsive element 113 so that, depending on the temperature in the cooling system, the fan may be directly connected to the motor or be able to overrun the motor. The freewheel coupling may be arranged on the input shaft of the pump.
