Filed: 1939-01-17
Abstract: 523,865. Two-part couplings. STANDARD TELEPHONES & CABLES, Ltd., and BEARD. J. R. Jan. 17, 1939, No. 1602. [Class 38 (i)] The contacts of a plug coupling, particularly for high-frequency work, are formed from a blank or blanks of sheet metal having three projecting portions and are electrically continuous throughout their length, while various types of contact can be made from the'same blanks bv removing a part or the whole of one of the projecting portions. A pair of blanks formed as shown in Fig. 1 and placed face to face form a pair of plugs 1, 2 and a socket 3 having no joints throughout the length of conducting part. When mounted in an insulating body this fitting forms a pair of shortcircuited plugs with a socket into which a similar plug can fit. If however the part 3 is cut off above the slot 5 a pair of shortcircuited plugs only is produced. If cut off below the top of the slot 5, the blank forms separate plugs 1, 2 to which leads may be attached by means of holes 6.

Title: Improvements in and relating to tuning indication systems in radio receivers
IPC: H03J3/14
Filed: 1942-02-09
Abstract: 554,388. Wireless receiving circuits. BRITISH THOMSON-HOUSTON CO., Ltd. Feb. 9, 1942, No. 1679. Convention date, Feb. 12, 1941. [Class 40 (v)] A tuned circuit for a radio receiver, in which oscillations are received varying in frequency with variations in tuning of the receiver, has means for providing two voltages which are equal when the frequency of the oscillations equals the frequency to which the circuit is tuned and varying differentially with respect to variations in frequency of the oscillations from the resonance frequency, together with means responsive to the two voltages for producing a resultant voltage having maximum intensity when the two voltages are equal and indicating means responsive to the said resultant voltage. As shown, the last intermediate frequency amplifier 1 of a frequency modulation receiver feeds a discriminator circuit 3 5, 12 of known type including diodes 6, 61 which produce across equal resistances 7, 8 voltages which are equal at the desired frequency and which vary differentially in accordance with deviations from this frequency. The voltages across 7, 8 are fed to the anodes of a pair of diodes 15, 16, the cathodes of which are connected to the junction of 7, 8 by equal resistances 17, 18 and whose anodes are connected by equal resistances 19, 20 the junction consisting either of a voltmeter 22 or a cathode ray tube 23 is connected between 21 and the junction of 17 and 18. According as to which way the frequency deviates one or other of the diodes 15, 16 ceases to conduct and it can be shown that the potential supplied to the indicator is always negative and equal to half the smaller of the voltages across 7 or 8. This becomes a maximum when the voltages are equal, that is when the circuit is tuned to the incoming frequency.

Abstract: 949,068. Locked oscillators. MARCONI Ltd. Sept. 11, 1961 [Jan. 17, 1961], No. 1956/61. Heading H3A. An oscillator, whose output appears at 12, is adapted to lock to an oscillatory electric signal applied at 1 without being disturbed by sudden phase reversals thereof by including within it an arrangement, which may consist of a limiting amplifier 2, a differentiating network 3, 4 and a detector 5, for producing from the incoming signal wave of known nominal frequency a pulse each time the wave passes through zero in a given direction. Also included are a source of oscillations of twice the nominal frequency and a phase discriminator 7, to which the pulses and oscillations are applied so as to produce an error correcting signal representative in sense and amplitude of the phase relation between the pulses and the oscillations. This signal is used to control the phase of the oscillations from the said source of oscillations, which may consist of an oscillator 8 providing the nominal frequency to the output 12, followed by a voltage doubler 9. One or other or both of the leads to the phase discriminator may contain a phase shifter, and the discriminator is preferably a simple gating circuit wherein the input pulses gate the input oscillations, which are then smoothed and applied as the error correcting signal to the generator 8. The invention is of application to telegraphy systems wherein " marks " (or " spaces ") in coded data are represented by the reversal of the phase of an oscillation, the output from the locked oscillator of the invention being used as the reference against which the incoming coded oscillation is compared in the detector of the telegraphy system.

Title: A process for improving the utility and crimping intensity of regenerated cellulose textile fibres
IPC: D06M11/63
Filed: 1958-01-22
Abstract: Regenerated cellulose textile fibres are treated for a short time with liquid ammonia at a temperature between -60 DEG C. and -35 DEG C. and are then rinsed in cold water.  The fibres may be in the unwoven condition or in the form of a woven fabric.  In one example, a fleece of regenerated cellulose staple fibres is dipped for 6 minutes into liquid ammonia at -60 DEG C. and then rinsed in cold water and dried.  In another example, a fabric woven from regenerated cellulose staple fibre yarns is treated in the same manner except that, when washed with cold water, it is held under tension in a tentering frame to prevent undue shrinkage.  The treatment improves the "crimping intensity and the "loop strength" of the fibres and reduces their "swelling value" without reducing their tenacity or elongation.
