Title: Improvements in or relating to the containing of molten metal in the manufacture of glass
IPC: C03B18/18
Filed: 1964-12-24
Abstract: 1,132,068. Molten metal baths for supporting glass. PILKINGTON BROS. Ltd., J. LAWRENSON, and A. S. ROBINSON. 13 Dec., 1965 [24 Dec., 1964], No. 52396/64. Heading C1M. [Also in Division F4] In supporting glass on a bath of molten metal, gaseous accumulations on or between adjacent blocks constituting a support structure for the molten metal are prevented by applying a negative pressure to the interstices between abutting faces of the blocks, the structure being enveloped by a shell and the interspace utilized to ensure equalization of the negative pressure, which is produced by suction applied to the interspace through a series of ducts in the shell.

Title: Semiconductor Current Converter.
IPC: H02M1/088
Filed: 1967-11-21
Abstract: 1,188,017. Converting. LICENTIA PATENT-VERWALTUNGS G.m.b.H. 21 Nov., 1967 [23 Nov., 1966], No. 52830/67. Heading H2F. Current conductors in an electric current converter are formed into groups of parallel bars such that the sum of the instantaneous current of the bars of each group is zero or a constant value. This prevents incorrect operation due to magnetic fields and reduces eddy current losses. In Fig. 3 a three-phase supply is converted to D.C. (by 11, 12) which is in turn converted by a thyristor bridge 16-19 to single-phase A.C. of frequency substantially above 50 Hertz. Considering one half cycle, current flows from choke 13, through a commutating choke 20 into the central conductor of group 17. From there it flows into the left-hand bar of group 16 through the parallel rectifiers to the right-hand bar and thus to lower terminal of the load. From the upper terminal of the load it continues downwards through the centre bar of 16 through thyristors between the outer bars of 17 back to the supply. In groups 16, for example, the current in the left-hand bar decreases stepwise at each thyristor but correspondingly increases stepwise in the right-hand bar. Thus the sum of the currents in these bars is constant and is equal and opposite to that in the central bar. In addition the current path lengths are equal. Accordingly the magnetic fields substantially cancel. Similar cancellation takes place in each arm and likewise in the bridge arrangement 24 of reactive current diodes, and between the centre and two outer bars of group 23 which connect rectifiers in parallel across choke 13 and in the two intermediate supply bars 22 and 23. The inductor 13, resistor 14 and ignition 15 are protective and smoothing devices. In Fig. 3 (not shown) the outer bars are of channel shape and a flat inner conductor 4 is sandwiched between them. The outer conductors may be hollow to carry cooling fluid.

Abstract: 1,172,355. Photo-conductive materials. RENKER-BELIPA G.m.b.H. 12 Dec., 1966, No. 55586/66. Heading C3R. [Also in Division H1] An electrophotographic recording material comprises a layer of a photo-conductive reaction product formed by reaction between a compound containing at least one isocyanate group and a non-photo-conductive aryl heterocyclic or unsaturated aliphatic compound having at least one group capable of reacting with an isocyanate group. The photo-conductive layer may be produced before its application to a base or it may be produced from the reaction components on the base material directly. The base may be electrically conducting, semi-conducting or non-conducting. Conventional sensitizers may be added to the photo-conductive material as may photo-conductors of other kinds such as organic photo-conductors, photo-conductive pigments and photo-conductive metal compounds, particularly zinc oxide. Lists of numerous suitable compounds containing isocyanate groups and non-photo-conductive compounds containing groups capable of reacting with isocyanate groups are given. In a typical example, a solution was formed if N-diethyl-N- acetyl - p - phenylenediamine, cyclohexanone and an isocyanate prepared by reacting 1 mole of trimethylol propane with 3 moles of 2,4- or 2,6-toluylene diisocyanate and dissolved in ethyl acetate.

Abstract: 1,205,095. Pure fluid oscillators. CORNING GLASS WORKS. Nov.25, 1968, No.55730/68. Heading G3H. [Also in Division G4] A fluid oscillator comprises a bi-stable amplifier 21 having an inlet nozzle 20 and output passages 30,32 feeding inlet nozzles 40, 60 of mono-stable amplifiers 38, 58 each of which is biased to feed a straight through outlet passage, 52, 72, and has a passage, 56, 76, providing feedback to one of the control orifices 34, 36 of amplifier 21 when pressure is applied to control orifices 80, 82 through a common inlet 78. In operation with the power stream flowing along the passages 32, 52, application of pressure to inlet 78 first transfers the power stream to passage 56 where it deflects the power stream to passages 30, 72 and, if the pressure is maintained at inlet 78, the power stream is diverted to passage 76 and then passages 32, 52 so causing the device to oscillate at a frequency determined by the dimensions of the device. By applying pulses instead of a constant pressure to inlet 78 the device can operate digitally as a counter.

The pressure reducers may be of the type comprising a weighted float 32, Fig. 4, in a conical casing 31, an increase in flow causing the float to rise to increase the flow cross-section whilst retaining a constant pressure reduction. In Fig. 3, the tube 70 is connected directly to header 25 and the pressure reducers 28 . . . 30 are designed so that the pressure reduction is greater for the lower level tubes than the upper tubes. The steam generator 4 shown, Fig. 1, is incorporated in a nuclear reactor, the heat transfer gas being circulated over the generator tubes by blowers 6. In Fig. 5 (not shown) the tubes are arranged in groups 41 . . . 43 of closely adjacent tubes with one pressure reducer, e.g. 47, associated with a group of tubes. The pressure reducers may be arranged in series or in parallel to produce greater pressure drops or greater flow rates for tubes at varying levels.
