Abstract: 307,087. Smith, W. S., Garnett, H. J., and Channon, H., C. Sept. 2, 1927. Loaded cables; insulating coverings for cables and conductors.-In order to transmit over distances of the order of 2,000 nautical miles, a telephone cable is loaded with tape less than 0.0015 inch thick which is formed of loading alloy such as that described in Specification 284,789, [Class 82 (i), Metals, Extracting &c.], having, after heat treatment, a high specific resistance, for instance, 100 microhms per cm. cube, and an initial permeability between 300 and 800. Preferably, the tape is 0.001 inch thick, and is applied and annealed in the manner described in Specification 282,504. In order to reduce leakance, the cable is insulated by a mixture of gutta-percha and balata treated to remove all protein and cellulose matter by dissolving the gum mixture in benzene or petroleum, and removing the impurities as sediment, or by filtration. The pure gum is then recovered by evaporation or by freezing out. A preservative such as tannin may be added to the gum mixture. The interstices of the loaded cable are filled, before covering, with a pressure-equalizing medium comprising a non-volatile paraffin hydrocarbon, such as petroleum jelly or medicinal paraffin, to which rubber, guttapercha or balata may be added as a thickener. Resin may be added to increase the viscosity. Mixtures which are stated to be suitable for the pressureequalizing medium are: rubber 14 parts, soft yellow paraffin 86 parts; rubber 40 parts, medicinal paraffin 60 parts; rubber 10 parts, soft yellow paraffin 67 parts, medicinal paraffin 23 parts; or, soft yellow paraffin 57 parts, balata resin 40 parts, crepe rubber 3 parts.

Title: Pulse width modulator
IPC: H03K7/08
Filed: 1974-05-23
Abstract: 1448770 Pulse width modulation CONTROL DATA CORP 23 May 1974 [22 Oct 1973] 22123/74 Headings H4L and H3T An arrangement for providing width modulated pulses incorporates an integrator stage where a first input signal V1 is applied to the inverting input of an inverting amplifier 10 and a comparator stage incorporating a switchable inverting amplifier 11, the integrator output Va being applied to the inverting input of amplifier 11 and a second input V2 being applied to the non-inverting input. When the integrated value reaches the value of the second input, the comparator switches and provides an output V o  which (by triggering a monostable multivibrator 12 whose output controls an FET such that the integrator capacitor C is discharged) resets the integrator. The pulses V o  delivered by the comparator during the integrating periods  have a width inversely proportional to the first input V1 and directly proportional to the second input V2. In a second embodiment (Fig. 2, not shown) the monostable multibrator, which sets a fixed delay time between pulses, is replaced by an integrator-comparator system similar to the stages 10 and 11 in Fig. 1 and provided with two (or more) further inputs so that the opposite going pulses can also be width controlled. A modification of this second embodiment is described (Fig. 4, not shown) in which a further inverting amplifier is connected ahead of the integrator so that an output whose pulse width is proportional to a constant and the inverse of one applied voltage can be produced.

Title: Channel multiplier
IPC: C03B23/203
Filed: 1973-05-16
Abstract: 1423543 Channel plates PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 16 May 1973 [19 May 1972] 23234/73 Heading C1M [Also in Division H1] A channel plate is composed of a stack of curved microchannel layers formed by compression between ribbed tools, the curvature of adjacent channels being the same and extending in the same direction. " Curved " and " curvature " include channels which (as in the drawings) are bent rather than curved, i.e. follow substantially a series of straight lines. In the manufacture, straight glass microchannels of the same cross-section are arranged to form a layer 1 (Fig. 1), the layer arranged transversely between the ribbed tools 30, 31, subsequently distorting the layer under the influence of heat and transverse force C, stacking a number of layers thus profiled, forming therefrom a compact boule by thermal treatment, and cutting the boule along planes transverse to the channel axes to obtain curved plate structures (Fig. 4, not shown). The microchannels may have circular, square, rectangular, triangular or polygonal cross-sections for example. Each microchannel in Fig. 1 may be replaced by a small number of microchannels to form a compact bundle of square cross-section. The pressing tool may be of stainless steel covered with tungsten carbide and may include the heating elements. The temperature of monolayer 1 is preferably raised to a value (e.g. 500 C.) such that the glass assumes a phase between the plastic and the elastic, and compression effected under vacuum or in a reducing atmosphere to minimize metal oxidation. The profiling may be combined with the fusing together of adjacent glass fibres of the monolayer, one edge being pressed flush with abutment 34 by a force C which is not at 90 degrees with the monolayer plane. Stacked monolayers as in Fig. 4 (not shown) may be fused by a thermal pressure treatment between similar tools. A number of monolayers may be profiled simultaneously using profiled separating element 51 which may be of tungsten carbide covered stainless steel to prevent adhesion to the glass (Fig. 5, not shown).
