Abstract: 1,223,169. Electric incandescent lamps. GENERAL ELECTRIC CO. 25 Oct., 1968 [8 Nov., 1967], No. 50866/68. Heading H1F. The light output of an electric incandescent lamp is increased by placing within the lamp envelope a quantity of at least one vaporizable halide, other than a fluoride, of Sn, Sb, Zn, Cd, Pb, Hg, Ge or As which is at most only partly dissociated during lamp operation so as to remain in the molecular state in the vicinity of the filament and is excited by the thermal energy of the filament to emit molecular spectra. The halide is present in a amount sufficient to provide a partial pressure between 0.1 and 500 torr during operation, and mercury may also be present in an amount sufficient to produce a pressure between 1 and 20 atmospheres.

Abstract: 1,190,516. Centrifugal separators, centrifugal filters. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 11 Nov., 1968 [13 Nov., 1967], No. 53316/68. Headings B1D and B2P. [Also in Division C1] Liquid is removed from a liquid suspension of particles of greater specific weight than that of the liquid by passing the liquid through openings 6 in the curved surface of a hollow body 1, which rotates about its own axis in the suspension, and discharging the liquid from the hollow space within the body through a line 5 coaxially connected to the body. The body may be cylindrical, slightly barrel-shaped or frusto-conical. The particles may consist of agglomerates of a very finely divided substance and a binding agent which are formed in the liquid in an annular space 7 between a housing 2 and a cylinder 3 coupled to the cylindrical body 1 and rotated therewith by means of the line 5 which is in the form of a hollow shaft. The openings may be radial or oblique, as shown in Figs. 3 and 4. In Fig. 3 the walls of the openings 15 are rounded and in Fig. 4, the openings 19 are formed between angularly arranged flat baffles 18. In operation, the fluid may be forced through the openings or pumped from the space within the body 1. Agglomerates entrained with the liquid towards the rotating body 1 are prevented from coming into contact therewith by the action of centrifugal force arising from the rotation imparted to the liquid by the body in its immediate vicinity. If the number of agglomerates become too large some may be carried off through a tube 9 by opening a valve 8. The agglomerating and separating device may be used for the agglomeration of carbon black or coal dust from water with the aid of a heavy oil or bitumen to form pellets or for the purification of water contaminated with oil.

A ceramic sheet having a surface roughness of no more than 8 micro inches is produced by mixing a refractory powder of particle size less than 2 microns with a thermoplastic binder and a solvent, removing at least a major part of the solvent during or after mixing to produce a dry friable mass, heating and compacting the mass between rollers to orientate the refractory grains, polishing the sheet so formed, e.g. by passing it between polishing rollers, and firing to remove the binder. The refractory powder may be Al2O3, BeO, MgO, steatite, MgAl2O4, BaTiO3, or ZrTiO3. The binder may be a mixture of a vinyl chloride copolymer, a wax, and a plasticizer. The solvent may be toluene, xylene, MEK or acetone. The heated rollers may be at 50-70‹ C. and the mass may be passed through 5-10 times to reduce its thickness to 0À004- 0À02 inch. The sheet may be fired at 1625‹ or 1550‹ C. The Al2O3 used may have a particle size of 0À3 Á or 1-2 Á, or mixtures of these materials may be used, containing 5, 10 or 15% of the 0À3 Á size.

[Also in Division F2] A tape-capstan, Fig. 4, has a portion 28 for feeding the tape, a portion 27 for engaging either of two drive rollers and a brake portion 34, the whole being journalled in a rocking mounting 21 controlled by a solenoid 24 and carrying a T-piece 36 marginally wider than the diameter 27. Drive wheels 25, 26, Fig. 3, are oppositely driven by belt means (Fig. 5, not shown) and brake arms 32, 33 are pulled in by solenoid 30 to act, first on one or other end of T-piece 36 to disengage the drive, secondly to centralize the arm 19 and finally to engage the brake surface 34. Light brake tension is then applied by compression spring 35 to hold the capstan, the drive diameter 27 now just extending beyond the limits of the T-piece 36. On restarting, the angularity of the arm 19 is such that one end of the T-piece 36 disengages a brake arm (32) from the surface 34 just before diameter 27 engages the drive roller (25). A logic circuit controls the solenoids 23, 24 30 to prevent simultaneous engagement of drive and brake (Fig. 6, not shown). Tape-tension is secured by vacuum-column or resilient arm means (not detailed).

The long edges 12 of elongate strip 11 of printed or woven fabric or plastics are folded by machine to abut each other on the reverse side of the belt i.e. that side nearer the wearer in use. A machine stitches the strip with threads 13 about “ inch apart and parallel to the length of the strip. The threads are relatively elastic compared with the strip material and hold the folds in place and cause the strip to form transverse puckers 15. The strip is steamed to shrink it, cut to length and passed through loops in buckles (16) and stitched to itself at (17). A fabric strip 18 may conceal the join on the reverse side of the belt. The long edges may be merely folded over to form hems secured by elastic or other stitches. The elastic may be natural or synthetic rubber. The strip may be folded and stitched and optionally steamed in a continuous process. Strips of different colours may be elastically stitched together along their length.

In a system for identifying two frequencies f1, f2 existing together in a complex waveform, the waveform S(t) is sampled at 3 for polarity, to obtain a first series of pulses (1 or 0), which are applied to a two-stage shift register 6, 7 and the outputs representing successive pairs are compared in a modulo-2 adder 8 which gives a "0" when the inputs are the same and "1" when they are different, the output signals from adder 8 are applied to a 5-stage shift register 9-13, the first two stages 9, 10 being connected to AND gate 14, the first and third, 9 and 11 to AND gate 15 and the "0" outputs from all the stages to AND gate 16, the outputs from the three gates being applied to an OR gate 17. The output signals of OR gate 17 are differentiated at 18 and applied to a bi-stable unit 19, to produce a signal y(t) having a frequency equal to half the difference between the two input frequencies, i.e. ¢(f2 - f1). This signal is applied to a modulo-2 adder 21, receiving signals from sampling device 20 via delay 31, and the adder generates a second train of pulses having a frequency equal to half the sum of the two input frequencies, i.e. ¢(f1 + f2). The sampling pulses are generated at 4 and applied via a frequency doubler 5 to sampler 3 and direct to sampler 20. The sum and difference frequency signals F1 and F2 are converted to a digital representation of the frequency by circuits 22, 23 (Fig. 2, not shown), which are as described in Specification 1,123,641. The actual values of the frequencies f1 and f2 are computed at 24 and indicated on leads 25-30.
