Title: Improvements in or relating to signalling systems employing pulse-width modulation
IPC: H03K7/08
Filed: 1946-06-06
Abstract: 628,555. Pulse modulation ; pulse generating circuits. PHILIPS LAMPS, Ltd. June 6, 1946, No. 17292. Convention date, Sept. 25, 1945. [Classes 40 (v) and 40 (vi)] A signal voltage 1, Fig. 2, of variable amplitude to be transmitted is converted into a wave 1<1> discontinuously changing at equal time intervals to the value of the signal voltage at these instants and a sawtooth voltage of same frequency as the discontinuous changes added to the wave, and the combined voltage 3<1> applied to a valve having a threshold bias 4 so that the anode circuit is energized with pulses a<1>, b<1>, the variation in duration of which is strictly proportional to the value of the signal voltage at equal intervals of time t<1>, t<2>, t<3>. The discontinuous changes take place during the fly-back periods of the sawtooth voltage so that the pulse duration modulation may extend over the whole interval between pulses. The signal voltage is applied through a transformer 7, Fig. 3, to a pair of valves 5, 6 with reciprocally coupled anodes and cathodes and at periodic intervals when the valve grids are driven positive by short pulses derived from the saw-tooth voltage, a voltage is induced in an output condenser 8 equal to the signal voltage of these intervals, and is retained by the condenser between pulses if the resistance 9 is of high value. The ends of the pulses in the anode circuit of a threshold bias stage (Fig. 5, not shown), may be differentiated to produce short pulses of opposite polarity, one set of which is equi-spaced and may be suppressed and the other set of which is phase modulated in accordance with the original signal and may be used to modulate a carrier wave.

Title: Improvements in or relating to artificial limbs and methods of making the same
IPC: A61F2/50
Filed: 1932-06-20
Abstract: 391,634. Artificial limbs. DAVIES, C. H., 1136, Girard Avenue, Philadelphia, U.S.A. June 20, 1932, No. 17342. [Class 81 (ii).] A hollow metallic artificial limb member is formed by working in stages upon a flat or curved sheet of thin metal, such as aluminium or alloys thereof, to produce a one-piece seamless tubular element, closed at one end, and then shaping this to the configuration of the limb. The metal sheet is spun or compressed over mandrels of progressively diminishing diameter until it assumes first a basin-like form and finally the form of a tube d, having coaxial zones of different diameters along its length. By spinning or compressing over a tapering mandrel f, the open end may be caused to conform to the shape of the limb stump and the tube assumes the form indicated at e. If the limb is to be used, however, with a socket member fitting the stump, shaping of the open end is unnecessary The element d or e is now bent or distorted to correspond with the shape of the limb and is expanded to that shape in a mould. The mould may be a composite one formed of main mould sections and interposed shim mould sections to form a mould of the required length as described in Specification 383,230, [Group XXII], and the expansion may be effected by water pressure as described in Specification 383,231, except that the fluid is introduced through one end only. The mould is shaped to form a V-shaped groove in the knee end for accommodating a check cord and, in the opposite surface, a recess i, the ends of which co-operate with a stop on the inner surface of the front part of the shim element to limit the extent of movement. Projections k may also be formed through which holes are bored for the pivot bolt which may be fitted with ball bearings. A covering, for example, of artificial cellulosic material or a plastic material with a nitrocellulose or cellulose acetate base, may be applied as described in Specification 383,231. For example, a softened tube of the material may be stretched over the limb and allowed to contract and harden. The colour may resemble natural skin.
