Abstract: 1289713 Float glass tank GLAVERBEL 5 Sept 1969 44043/69 Heading C1M In apparatus for carrying out the float glass process contamination of the liquid bath by a vitreous phase released by the refractory material forming the tank containing the bath is prevented by placing one or more solid metal screens in contact with and overlying at least part of the refractory material. The screen is composed of at least one plate preferably of tungsten and from ¢ to 10 mm. thick. The plates 22 may be arranged on refractory blocks 20, with the gaps 24 therebetween spaced from the joints between the blocks and sufficiently small to prevent the escape of vitreous material. Alternatively the plates may overlap with graphite powder being disposed between the overlapping edges (Fig. 5, not shown), or the gap is disposed above a groove filled with graphite powder (Fig. 6, not shown). The refractory blocks may be heated or cooled by liquid passing through passageways 28 therein which have metal stowage rods 30 passing therethrough. The float bath 12 may be a molten salt or a metal such as silver or tin. Specifications 1,289,714 and 1,289,175 are referred to.

Title: Gain control arrangements
IPC: H04N9/76
Filed: 1970-05-02
Abstract: 1349943 Gain control EMI Ltd 10 June 1971 [2 May 1970] 21215/70 Headings H4R and H4F A gain control arrangement comprises a plurality of gain control circuits each including a non-linear resistor and varying the gain of a corresponding channel in proportion to the current through its non-linear resistor, and a constant current source arranged to distribute its current between the non-linear resistors to maintain the sum of the gains constant. Two and three channel arrangements for mixing and/or fading of colour television video signals are described. In each the outputs are combined in an adding circuit and the level of the synchronizing signals and colour bursts is constant and independent of the gain. In the two channel fading arrangement the full signal is applied to one channel and the synchronizing signals and colour bursts only applied to the other channel. Manual adjustment of a potentiometer varies only the level of the picture signals. In the three channel arrangement shown two separate video signals are applied at inputs 1 and 1<SP>1</SP>. The synchronizing signals and colour bursts from these channels are also supplied via separators 26, 27 as inputs to a video switch 28 forming an input to a third channel. Each channel includes an amplifier 4 to 4<SP>11</SP> and a series non-linear resistor in the form of a diode 3 to 3<SP>11</SP>. The resistance of each of these diodes is varied by passing a direct current through it, the gain of each channel being proportional to the direct current. The direct currents are derived from a constant current source 17 which maintains the total current and the sum of the gains of the channels constant. The relative values of the currents is controlled by transistors 18 to 20 controlled by potentiometers 21 and 22 and a potential divider 23. A comparator 29 determines which of the potential dividers is set to the higher level and controls the video switch to supply one or other of the sets of synchronizing signals and colour bursts to the third channel. In operation two complete colour signals not necessarily synchronized are applied at 1 and 1<SP>1</SP> with one of the potentiometers set for high gain in that one channel, the comparator setting the video switch to derive the synchronizing and colour burst signals for the third channel from the said one channel. As the potentiometers are adjusted the one channel fades to black, the video switch changes over to synchronizing signals from the second channel and the second channel is faded in. The level of the synchronizing signals and colour bursts is maintained constant throughout the operation. A relay 31 controlled by a synchronization detector not detailed can switch the third channel to zero gain if the two channels are synchronized.

As shown, slide member 30 can be advanced by actuation of handles 16, 22. A screw 36 protruding from member 30 mounts first and second crimping dies 40, 42 and a shear blade actuator 44. The anvil member 46 has first and second crimping anvils 46a, 46b and movably supports a shear blade 48. A compression spring 68 acts between dies 40, 42. A guide 61 serves to guide a strip of terminals through the tool. In operation the spring 68 ensures that die 40 advances ahead of die 42 so that die 40 reaches its full closure position with respect to its opposite anvil 46a before die 42 reaches its full closure position with respect to its opposite anvil 46b. Thus, the dies 40, 42 successively operate to crimp first terminal ears about conductor based end 62 and second terminal ears about conductor insulation 63. For this purpose a degree of lost motion is possible between dies 40, 42 as afforded by enlargement of the slot 40a which mounts die 40 on screw 36. Thereafter, blade actuator 44 urges the shear blade 48 to move relative to anvil member 46 against return spring 72, whereupon the blade and anvil member co-operate to sever the crimped terminal from the strip. The tool is adjustable for handling conductors of various gauge wires, by varying the amount of protrusion of the screw 36 from slide member 30. This is done by rotating the screw by means of a lever 37 extending therefrom.
