Title: Improvements in and relating to synchronising devices for telegraphic receivers
IPC: H04L7/00
Filed: 1944-05-04
Abstract: 579,499. Synchronous movements. OLSEN, L. C. May 4, 1944, No. 8439. [Class 40 (iii)] For synchronizing Wheatstone morse or other telegraphic receivers with incoming signals, an arm 3, Fig. 1 (side elevation), carrying a double pawl 8a, 8b is reciprocated by a cam follower 5, and is positioned upwards or downwards, so as to effect corrections through a ratchet-wheel 12, by a split flexible tongue 13, Fig. 2 (end elevation), which is rocked in response to received signals by the tongue 15 of a synchronizing relay ; or the split tongue 13 may be integral with the tongue of the relay, Fig. 4 (not shown). When the upper edge of the tongue 13 is at the uppermost of the levels x, Fig. 1 (i.e. during a spacing period), the pawls 8a, 8b are free of the ratchetwheel 12 if the upper prong 13b is against the pawl 8a as shown, but if the upper prong 13b. is against the step 9b, the lower pawl 8b engages the ratchet-wheel during its rightward movement. Similarly, when the lower edge of the tongue 13 is at the lowermost of the levels x (i.e. during a marking period), the upper pawl 8a is free of or engageable with the ratchetwheel 12 according as the lower prong 13a is upon the pawl 8b or the step 9a. In the absence of signals, the double pawl 8a, 8b is pushed by the ratchet teeth into the disengaging position during its leftward movement and is thereafter supported by the upper prong 13b engaging the pawl 8a or step 9b as the case may be. When signals arrive, the cam 6 makes one revolution per dot period, the marking and spacing half-periods for a dot occurring while the arm 3 is to the left and to the right, respectively, of its mid-position; if through errors of synchronism these conditions do not hold, the mechanism hunts until they are attained. When the signals arrive in synchronism, the tongue 13 moves, in response to a change of line condition, at a moment when the steps 9a, 9b are to the right and free of it, and the timing is such that the ratchet-wheel 12 is not actuated so long as synchronism continues. For early signals, on the other hand, the ratchet-wheel 12 applies a correction by clockwise movement when the upper pawl 8a engages it after being depressed in response to a change from spacing to marking, the lower prong 13a having engaged the lower step 9a during the preceding spacing condition just before the end of the period during which the tongue 13 is free of the steps 9a, 9b. For late signals, the ratchet-wheel applies a correction by anti-clockwise movement in the corresponding way.

Title: Heat transfer system
IPC: F28D17/00
Filed: 1973-02-21
Abstract: 1379183 Cooling electrical components UNITED AIRCRAFT PRODUCTS Inc 21 Feb 1973 [22 Feb 1972] 8499/73 Heading F4U A heat transfer system for cooling electrical components 24 disposed on cold plates 10, 11, includes the two cold plates 10, 11 each formed of flat plate elements 12, 13 separated by marginal spacer strips 14, 15 and provided with a fin strip 19 disposed in the narrow interior space 16, a central reservoir 28, containing both water and a heat exchanger 41. a housing 49 enclosing the cold plates, and cooling elements 53 disposed on the outside of the housing. In operation, heat dissipated by the components 24, is withdrawn by passing a cooling fluid first through plate 11 and then, via a conduit, plate 10. The fluid then passes via a valve 38 to the heat exchanger 41 and a reservoir 85 to pump 86. Steam created in reservoir 28 passes via an outlet 46 and conduit 44 to a bellows valve 45 and outlet 71 on the housing 49. If liquid flowing to the valve 38 is too hot, it is directed by the valve 38 to the cooling elements 53 which may be disposed in a cooling airstream, for example on an aircraft. The cooling liquid then passes back to the valve 38, and heat exchanger 41. However, it may occur especially in an aircraft, that the housing is heated by the air flow and therefore prevents efficient cooling. In this case the diverted valve 38 prevents the fluid from passing to the elements 53. Steam escaping from 71 creates a zone of low pressure thus allowing boiling of the water to take place in reservoir 28 at a lower pressure and therefore at a lower temperature.

Filed: 1922-03-24
Abstract: 181,328. Western Electric Co., Ltd., (Assignees of Carson, J. R., Clark, A. B., and Mills, J.). June 4, 1921, [Convention date]. Telephone circicits loaded to improve transmission.-Relates to circuits loaded according to the Pupin-Campbell system as indicated in Fig. 1, wherein loading-coils 1 - - 4 and amplifiers A are interposed at regular intervals between terminal stations x, y. According to the invention, the loading over the entire length of the line is reduced per unit length of the line as its electrical length is increased so as to attain maximum quality of speech transmission having regard to the three following factors : (1) equal attenuation for all current-frequencies within the telephonic range; (2) echo effects arising from the time of transmission of the speech-currents; and (3) transient distortioneffects due to the timeintervad required for the speech-current to buildup at the receiving end. Mathematical formulµ are given showing the value of loading required for the clearest speech-transmission over a given length of line having specified values of capacity and inductance, and designed to transmit all speech-frequencies throughout a definite range under equal attenuation, and within stated time limits for transmission and building-up.

Abstract: 1,117,176. Gyromagnetic spectrometers. COMMISSARIAT A L'ENERGIE ATOMIQUE. Feb.23, 1967 [Feb.26, 1966], No.8644/67. Heading G1N. In a gyromagnetic spectrometer with a superhetrodyne receiver circuit the local oscillator is synchronized relative to the main oscillator (by comparing the "transmitter" I. F. with a reference crystal oscillator), and the main oscillator is frequency controlled by comparing the received I. F. from the sample cavity with the transmitter I. F. As described the main and local oscillators 1, 2 are reflex klystrons. The main oscillator feeds the spectrometer cavity through a ring- circulator, and the cavity output signal is mixed at 12 with the local oscillator signal to produce the received I.F. Synchronising Main and Loc Oscillators Output of the main and local oscillators 1, 2, is mixed at 16 and the resultant "transmitter" I. F. is phase compared with a signal from a reference quartz oscillator. The output t 1  of the phase discriminator controls the local oscillator 2. Control of Main Oscillator The received I.F. is compared with the "transmitter" I.F. in synchronous detectors 23, 24, the reference input to detector 24 being phaseshifted by 90 degrees. The output t 2  of the quadrature detector controls the main oscillator frequency towards resonance with the sample. The signal from detector 23 is used for sample absorption measurements.

Filed: 1945-04-09
Abstract: 590,017. Capacitance measurements ; determining dimensions of materials. SMITH, S. J. April 9, 1945, No. 8715. [Class 37] [Also in Group XXXVIII] A liquid level gauge of the kind in which the rise and fall of the liquid varies the capacitance of a condenser comprises a measuring condenser 10 and a relatively fixed reference condenser 9 connected in the arms of a bridge network 8. A source of alternating current 1 is connected to the primary winding 2 of a transformer 3, the core of which becomes saturated so that the output from the secondary winding 4 contains many harmonics. This output is fed over a cable 5 to a circuit, including an inductance 6 and condenser 7, which is tuned to the frequency of a desired harmonic. The output of the circuit 6, 7 is applied to the bridge network 8, the remaining two arms of which are formed by the primary winding 11 of a transformer 12. The secondary winding 13 is connected through a rectifier 16 with the moving coil of an indicating instrument 15. The condenser 10 is the measuring condenser of a liquid contents guage and is connected with the bridge 8 over a coaxial cable 18. The reference condenser 9 is normally fixed but may be adjustable for zero setting &c. The scale of the indicator 15 may be calibrated in terms of liquid level. For use on aircraft where a source of 400 c.p.s. is available, the circuit 6, 7 may be tuned to select the fifth harmonic. Compensation for fluctuations in frequency of the source 1 may be provided by tuning the circuit 6, 7 to a frequency somewhat below that of the desired harmonic so that if the frequency of the source increases the output of the bridge is reduced, thus off-setting the reduced reactance of the condenser 10. The apparatus with the exception of the condenser 10 and indicator 15 may be constructed as a self-contained unit. Specification 560,872 is referred to.

A circular latch needle machine for producing a fleece fabric is provided with sinkers 12 which project outwardly between the needles. The sinkers 12 have two loop drawing levels 13, 14 one of which 13 is behind a nose 15. Co-operating with each sinker is a locking slide 16 which serves to secure the backing or inlay yarn 3 behind the nose 15 at a level 13, so that as the sinkers 12 and slides 16 are withdrawn the yarn 3 is drawn around the selected raised needles, Fig. 6. Thereafter all of the needles are raised to clearing height, the previously unselected needles passing in front of the yarn 3 which is held back by the sinkers and slides. A binding yarn 6 is then fed to the needles and drawn by them over the sinkers at the level 13 behind the noses 15, the slides 16 having been withdrawn so that the yarn 3 is cast-off the selected needles, Fig. 8. The needles are then raised again but insufficiently to clear the yarn 6 from their latches and the covering or facing yarn 11 is fed to them at the level 14, Fig. 10, the slides 16 having previously been advanced to enclose yarn 6 to ensure that the loops of the yarn 6 serve to open the latches. The needles subsequently knit drawing the yarn 11 into loops over the lower edge level 14 of the sinkers and at the same time the sinkers are withdrawn so that the loops of yarn 6 pass over the nose 15 and are drawn in plating relationship with the covering yarn 11. The machine may be provided with the normal inwardly directed sinkers at a level beneath the sinkers 12 or alternatively they may be dispensed with. U.S.A.
