IPC: H04Q1/446
Filed: 1936-10-28
Abstract: 483,922. Exchange systems. TELEPHONE MANUFACTURING CO., Ltd., and PADDLE, L. H. Oct. 28, 1936, No. 29281. [Class 40 (iv)] [Also in Group XL] A signal receiver which distinguishes between a signal of speech frequency and the same frequency occurring in speech by virtue of the steep wave front of the signal comprises a valve the anode current of which is modified on receipt of the frequency, a relay in the anode circuit being operated or released by a surge due to an inductance in the anode circuit. As shown, incoming current after amplification at V1 if necessary, is fed to a transformer T1 tuned to the signalling frequency, the rectified output of the transformer being used to decrease the bias of valve V2, but the variation of anode current due to variation of bias is insufficient to operate the relay SR. An inductance L1 and variable resistance R2 are connected in parallel with the relay, the current in the-two branches being adjusted by R2, and if a sudden change of current occurs, the momentary A.C. surge across L1 is rectified at 12 and operates the relay. Valve V2 is arranged to act as a limiter by virtue of grid current flow and its grid circuit is decoupled to prevent the relay from being operated by retro-action. In order to allow a limited variation of signal frequency, transformer T1 may be replaced by two transformers in series tuned to slightly different frequencies.

Abstract: 851,173. Valves. SPECIALITY VALVES Ltd. July 19, 1957 [Sept. 26, 1956], No. 29418/56. Class 135. A cup-shaped valvebody 10 which is secured in the upper wall of a container C has a central portion 12 that houses a valve seat 15 through which passes the tubular stem 19 of a closure member having a flange on its inner end that co-operates with the underside of the seat. The inner end of the member 19 is closed by a disc 25 carried in a cup 26 loaded by a spring 27 within a member 28 press-fitted into the portion 12 and having an enlarged end 30 that is disposed in the upper end of a dip tube 31. An operating button 32, which surrounds the outer end of the stem 19, is provided with a discharge orifice 34. Direct downward movement of the button 32 causes axial displacement of the closure from the seat 15, whereby pressure fluid from the container passes to the orifice 34 via a radial bore at the inner end of the stem 19. The valve may also be actuated by pressing the button 32 laterally whereupon the radial bore is uncovered due to tilting of the closure. The container is filled either by supplying the medium to the outer end of the stem 19 at sufficient pressure to unseat the disc 25 from the latter or by sealing the body 10 in position after filling through the opening normally occupied thereby. The body 10, closure, cup 26 and member 28 may be of tin-plated mild steel or stainless steel; as a further alternative the last two members may be of nylon. The spring 27 is made of stainless steel and the tube 31 and button 32 of polythene whilst the discs 15, 25 may be of rubber or a flexible and solventresistant elastomer. According to the Provisional Specification, the disc 25 may be unseated by a rod carried by a cap with a discharge orifice which replaces the button 32, the rod passing through the stem 19 ; by this means a rapid discharge is effected through the relatively large cross-sectional area of the stem 19.

IPC: G01V1/40
Filed: 1967-06-30
Abstract: 1,176,350. Geophysical prospecting. INSTITUT FRANCAIS DU PETROLE DES CARBURANTS ET LUBRIFIANTS. 30 June, 1967 [1 July, 1966], No. 30366/67. Heading H4D. The permeability of a geological formation, i.e. the facility of the passage of fluids therethrough, is determined by taking the received signal in an acoustic well-logging device as it passes through the formation and plotting either the ratio of the values, for two of three consecutive half-cycles of the signal, of a parameter related to the peak amplitudes of the selected two half-cycles or the ratio of the values, for the half-cycle of maximum amplitude and an adjacent half-cycle, of a like parameter. In one apparatus the output of receiver R in the logging sonde, previously tested in an artificial standard bore-hole containing glass balls for distinguishing the unwanted "fore-runner" from a wanted received train such as D 12 , is fed via a threshold device 12 so as to eliminate background noise (and may be set after a trial run in the actual bore-hole through the geological formation of interest) to a switch 14 which is closed by half-cycle A 1 . Detection of the maximum amplitude h 2  of a successive halfcycle is effected by a coincidence circuit 15 and a circuit consisting of a differentiator 17, a multivibrator 19 and a further differentiator 21. Circuit 15 passes only the signal applied to its terminal 24 during a brief period corresponding to a pulse having the same polarity, e.g. 25; the output signals are directed to measuring means 25a, 26 which store amplitudes h 1 , h 2  which are applied to a divider 27 whose output is recorded in synchronism with the movement of the logging sonde through the bore-hole. In the embodiment the sonde starts from the bottom. In a modification the ratio h 3 /h 1  is recorded, Fig. 11 (not shown). The parameter proportional to peak amplitude of a half-cycle may be the slope of the tangent at the initial zero-crossing thereof: a signal D 35  is in this case obtained by differentiation of signal D 12 . Two emission frequencies, for measurements corresponding to different penetrations of the formation, may be employed: two transmitters and two receivers are utilized, Fig. 12 (not shown), the signals from the receivers being displayed on a cathode-ray tube which is photographed.
