Title: Improvements in or relating to apparatus for determining the flow resistance of breathing apparatus elements
IPC: A62B27/00
Filed: 1936-09-01
Abstract: 475,440. Respiratory appliances ;determining flow-resistance. MINE SAFETY APPLIANCES CO. Sept. 1, 1936, No. 23933. Convention date, Sept. 23, 1935. [Class 81 (ii)] [Also in Group XIX] The flow - resistance of gas - mask canisters or other respiratory appliance elements is determined by periodically passing air or other gas by a bellows 10 through the canister or the like 33, in one direction only, or alternately in one direction and then in the other, and measuring the pressure or suction above the canister as bv a manometer 39. The volume of gas passed is adjusted to that of breathing under various conditions by adjusting the stroke of the bellows, and the frequency by regulating the driving motor 13 by a rheostat 14. The pipe 27 connecting the bellows with the element 33 contains a branch-pipe 34 with a cock 35 and non- return valve 36 used in single-direction determinations, a regulating valve 26 and a cock-controlled branch 29 for a pressure gauge. The bellows is driven through a connecting rod 22 with turn-buckle length adjustment 23, a crank 18 with a crank-pin 18a adjustable in throw by a screw 19, and reducing gearing 16 driven by the motor 13. The manometer 39 comprises a U-tube, of the differential type (containing two liquids of differing densities), the limbs of the tube being connected through reservoirs 52, 53 to a common two-way tap 40. The tube has a constriction 46 at its lowest point and one limb 42 contains a non-return valve 45. The tap 40, in one position, connects the limb 42 to a pipe 58 leading to the pipe 27 close to the element 33, and the other limb to atmosphere through a pipe 59. The manometer is then unaffected by pressure and registers steady maximum suction only, liquid passing the valve 45 being unable to return. In the other position of tap 40, limb 42 is connected to atmosphere and the other limb to pipe 58, a steady maximum pressure reading being obtained. The limbs are connected by a byepass tube controlled by a cock 47 to re-set the manometer after each reading. The manometer 39 may be replaced by two manometers connected permanently to the pipe 27 and each provided with a non-return valve in one limb, a constriction, and a controlled byepass, whereby, when the valve 36 is cut off, steady readings are obtained respectively of the maximum pressure and maximum suction in pipe 27 due to the bellows strokes. The manometers may be of the differential or the single liquid type.

Title: Improvements in or relating to signal transmission systems
IPC: H03G7/02
Filed: 1951-10-22
Abstract: 722,813. Automatic control systems. TELEFONAKTIEBOLAGET L. M. ERICSSON. Oct. 22, 1951 [Oct. 20, 1950], No. 24607/51. Class 38 (4). [Also in Groups XXXIX and XL (c)] In a system in which signals are compressed before transmission according to the input/ output characteristic OKT, Fig. 1, and expanded on reception according to the characteristic OKT, Fig. 2, means are provided for ensuring that signal waveforms passing through the system remain undistorted. The invention is applied to a pulse multiplex system using one channel thereof to carry a pilot wave. Compression is effected by a circuit of the type shown, Fig. 3, in which if the signal is large enough to overcome the diode biases the diodes conductto introduce shunt resistances R4 into the network, thereby increasing the attenuation between the input and output terminals U1, U2. Expansion may be effected by the circuit of Fig. 27 in which the series diodes D9, D10 are normally non-conducting due to bias supplied over potentiometer R3 ... R6, but conduct when the signal overcomes the bias to decrease the attenuation between the input D and the output F. It is shown that if the points K in Figs. 1 and 2 do not correspond exactly odd harmonics are introduced into a signal; and if the biasing of the diodes in the compressor or expander is not symmetrical about the zero axis then even harmonics will be introduced. A pure sine wave is therefore introduced into the pilot channel and on receipt after demodulation this signal is passed to valve V1, Fig. 23, provided with an anode circuit tuned to the fundamental and its various harmonies. The harmonic component is fed via valves V2, V3 to tuned circuits from which outputs A2, B2, C2 are derived, the first output containing the third and fifth harmonics, the second containing the fourth harmonic, and the third containing the sixth harmonic. The output A2 is fed to a phase comparator fed with a reference signal of fundamental frequency derived from output A1 of valve V1. The D.C. output A3 from the phase comparator has magnitude and sign dependent on the magnitude and phase of the third and fifth harmonics and is applied to control a thermionic impedance V5, Fig. 27, contained in an attenuator network comprising resistance R1 and lamps G1, G2. The amplitude of the signal thus applied to the expander is thus controlled so that the discontinuity of slope of the characteristic occurs at the correct input signal amplitude. Fourth and sixth harmonic reference voltages B1, C1, Fig. 23, are obtained from a frequency-multiplier comprising diodes D1, D2 fed with the fundamental and these are applied respectively to two further phase comparators together with the fourth and sixth harmonic outputs B2, C2 from valve V3. The D.C. output voltages B3, C3 from these comparators are applied in series to control a thermionic impedance V6, thereby regulating the potential of the point E with respect to ground to improve the relationship between the positive and negative biases applied to the expander diodes D9, D10.
