Title: Process and apparatus for the manufacture of glass in sheet form
Inventor: PLUMAT EMILE
IPC: C03B15/02
Filed: 1968-09-12
Abstract: 1,246,673. Drawing sheet glass. GLAVERBEL. 12 Sept., 1968 [25 Sept., 1967], No. 43491/68. Heading CIM. In a process for manufacturing sheet glass by drawing a continuous ribbon from the surface of a bath of molten glass wherein an upper forward current of glass flows from the melting furnace into a drawing kiln over a cooler return current flowing back to the melting furnace, the glass in the surface region flows up to the meniscus at the base of the ribbon, but the glass entering the ribbon is shielded at the downstream side of the meniscus from contact by glass which has flowed further downstream and has cooled. The shielding is done by a barrier at least partially immersed in the glass on the downstream side and which so divides the upper current whereby either only the quantity or more than the quantity of glass drawn into the ribbon flows into the region of the meniscus. In one embodiment an L-shaped barrier comprises a vertical portion 20 located downstream of the meniscus and extending transversely of the bath 3 with the upper portion above the glass surface and a longitudinal portion 22 submerged in the glass, and extending upstream beyond the meniscus. The depth of immersion is determined by the rate of draw. In a further embodiment (Fig. 4) a debitence 42 is used together with a submerged L-shaped barrier 41, 43. The longitudinal portion 43 of the barrier extends upstream beneath the debitence to the shut off 44 and has a threshold 45 on its upper surface to prevent the formation of secondary vortices. Alternatively the barrier may comprise a single vertical member partially immersed in the glass downstream of the meniscus either with or without a debitense. The barrier member is preferably heated to control the glass temperature in the meniscus region and is preferably made of an electrically conducting material, e.g. a cast alumina refractory, or may have heating elements thereon e.g. MoSi 2 . It is preferred that the upstream facing surface of the vertical member and the upper surface of the longitudinal member of L-shaped shields be platinum coated to prevent erosion and this can serve as the conducting medium. To prevent heat from the vertical member affecting the down sheet it may be capped with an insulating member 21. -

Abstract: 1371205 Automatic control of fluid level SCHLOEMANN AG 22 Sept 1971 [22 Sept 1970] 44196/71 Heading G3R A regulator controlling the level of molten metal in a continuous casting installation, comprises a differenting element followed by an integrating element, and a proportional element in parallel with the series combination of the two. As shown, flow of metal from a tundish 1 into a mould 4 is controlled by a stopper 3. The level in the mould is detected by measuring at 6 the radiation from a radio-active source 5; the signal from 6 is transmitted by 11 to a comparator 14 which also receives a desired value signal S. The resultant error signal is fed to a proportional element 21, which has a feedback amplifier, and to a diode limiter 24 (to eliminate harmonies) and two differentiating elements 13a, 13b, (the second of which is for "time factor compensation") connected to an integrator 20. The combined outputs of 20 and 21 controls the flow regulating stopper 3 by electro-hydraulic mechanism 16 ... 19. The proportional factor in the control signal is made appreciably less than the integrated factor. The signal applied to the integrator is made of opposite sign to that applied to the proportional element. The invention maintains adequate control when the delivery tube 2 to the mould is suddenly cleared after a blockage.

Abstract: 1485093 Parking brake controls ATWOOD VACUUM MACHINE CO 29 Oct 1975 [20 Nov 1974] 44550/75 Heading F2E An energy absorbing member is loaded as a consequence of movement of the parking brake pedal or band lever and assists in unlocking the brake. As shown in Fig. 1, pedal 14 is locked in its applied position by engagement of a sector 25 with pawl 26. Movement of the pedal stresses a torsion spring 36 associated with the pedal pivot 16 and biasing an impact member 31. For brake release, a latch 40 is pivoted (by a solenoid 49 or manual link 53) out of engagement with the impacting member 31 allowing the latter to pivot anti-clockwise and strike the pawl (by way of complementary lugs 33, 34), so forcing it out of engagement with sector 25. The brake release springs acting through link 21 returns the pedal to its initial position. In the event of failure of spring 36 or impact member 31 continued movement of latch 40 will disengage the pawl (by abutment of parts 41 and 54). The energy absorbing spring may be a tension spring extending between the impact member and a fixed support and stressed by engagement of the pedal with the impact member during brake release (Fig. 7, not shown). Alternatively a compression spring storing energy as a result of relative movement between the pedal and the brake linkage on brake application may be employed (Fig. 8, not shown). As shown in Fig. 10 a hand brake lever 69 has a lost motion connection with the sector 73 allowing the handle to be returned to the horizontal after brake application. The impact member 81 is loaded by torsion spring 83 and its latch 87 can be released by a power actuator 90 or a button 93 in the handbrake. The brake release mechanism may be coupled to a vehicle gear selector. The energy absorbing springs can be replaced by rubber elements or gas springs and the impact member can be pivoted elsewhere than on the sector pivot.
