Title: Data transmission system by phase leading and lagging
IPC: H04L25/49
Filed: 1963-08-26
Abstract: 1,024,250. Data transmission. STANDARD TELEPHONES & CABLES Ltd. Aug. 26, 1963 [Aug. 24, 1962], No. 33756/63. Heading H4P. In a binary data transmission system each bit is represented by one complete constant length cycle of a waveform. The time at which the zero crossing within a cycle occurs relative to the mid-point of the cycle indicates whether the cycle represents a " 1 " bit or a " 0 " bit. Thus, in Fig. 2b, the first cycle, in which the zero crossing leads relative to the mid-cycle time, represents a " 1 " bit and the second cycle a " 0 " bit. The signal contains no high order transients since the transition from one bit to the next is fairly smooth. The amplitudes of the two parts of a cycle are chosen such that the average D.C. level is zero. The transmitter, Fig. 3 (not shown), comprises two units fed from a sine wave oscillator. One of these units provides " 1 " bit and the other " 0 " bit waveforms. These are gated to the line by the binary data. At the receiver, Fig. 4 (not shown), each positive-going transition starts a counter. If the subsequent negative-going transition occurs within one range of counting, e.g. 14-18 as in Fig. 2f and Fig. 2g, the receiver indicates a " 1 " bit, and if in a second range, e.g. 6-10, a " 0 " bit. If the transition is outside these ranges an error indicator operates. It may also operate if the next positive-going transition is not in the range 24-25 for example.

Abstract: 1429620 Eddy current testing INSTITUT DR FRIEDRICH FORSTER PRUFGERATEBAU 31 July 1974 [29 Sept 1973] 33855/74 Heading G1N The invention relates to eddy-current flaw testing apparatus employing phase selective circuits to provide two orthogonal components of the "flaw" signal. Herein the ratio of these components Uy max/ Ux max, Fig. 3, is used to determine the phase angle of the hysteresis loop axis, and provision is made not to pass-on a signal with a large X component. The Specification explains that a large X-axis component denotes a change in size of the test piece whereas the Y-axis component denotes a flaw.  In one embodiment, Fig. 4, X and Y signals from phase selective circuits (not shown) are fed to temporary stores to accumulate the maximum components of Uy and Ux. The limiting ratio of these components is set on potentiometers R 1 , R 2  in the input to differential amplifier 52 which outputs via gate 53 to cause F.E.T. 54 to pass on the Y-signal to the flaw trigger circuit 55. The minimum effective amplitude UT (to eliminate noise signals) is set by the threshold of triggers 41, 42 which actuate a "one shot" 47 to enable the gate 53, start the store-reset circuit 48, when the signal returns toward zero. This is detected by circuit 35 to enable AND gate 46 when the signal lies within the null-field square 28 Fig. 3. A further embodiment Fig. 5 (not shown) measures the flaw signal in all four quadrants with selector circuits responsive to the polarity of the output signals from a pair of ratio determining circuits.

Filed: 1947-12-22
Abstract: 655,326. Dashpots. HERBERT & SONS, Ltd., and HALL, R. Dec. 22, 1947, No. 33875. [Class 108(iii)] In a dashpot of the kind in which a piston works in a cylinder communicating with a reservoir space for the reception of fluid expelled from the cylinder during a working stroke of the piston, and having means for restricting the cross sectional area of the passage between the cylinder and reservoir, an inner open-ended cylinder within which the piston works is surrounded by an outer cylinder with a radial clearance and having one end closed, and adjacent the open end of the inner cylinder, and annular shoulders are formed one on the outer surface of the inner cylinder intermediate the open end thereof and the reservoir space and the other at a corresponding position on the inner surface of the outer cylinder and the shoulders have axially spaced surfaces thereon which cooperate to restrict fluid flow between the inner cylinder and the reservoir space. In the arrangement shown, an inner cylinder 2, open at its lower end 8 and having a piston 1 slidable therein, is surrounded, with radial clearance, by an outer cylinder 10 closed at its lower end and which is screwed on to an overhanging skirt portion 3b of the inner cylinder 2. The outer wall of the inner cylinder and the inner wall of the outer cylinder 10 are formed with complementary coned shoulders 9 and 16. respectively which co-operate to define a restriction 17 for the passage of oil from the lower part of the cylinder 2 through ports 7 to the upper part thereof and to a reservoir' space 21, during the working stroke of the piston 1. The damping action of the dashpot is adjustable in dependence upon the extent to which the cylinder 10 is screwed on to the skirt 3b, to vary, axially, the restriction 17. Relative rotation of the cylinders 2 and 10 is effected by means of a handle 19 carrying a resilient tongue 20 which engages serrations on a boss 18 at the base of the cylinder 10. The dashpot may be arranged to be double acting by the provision of a gland for the rod of the piston 1 and may be mounted at any angle to the vertical, or may be inverted. The co-operating faces of the shoulders 9, 16 may be radial. The lower end of the inner cylinder 2 may be closed and provided with radial ports therethrough. For vertical mounting arrangements, the ports 7 may be replaced by breathing holes at 7a. Also, the position of the fixing means for the dashpot and the adjusting handle may be reversed. In modifications, Fig. 2A and 2B (not shown), one of the shoulders 9, 16 is square and the other is coned or chamfered.

(Assignee of Aarts, C. ; 30, Laan van Leeuwensteijn, Voorburg, Holland.) Dec. 7, 1931, No. 33908. Convention date, Feb. 2. [Classes 68 (i) and 85.] Bore holes or wells are formed in the ground by applying heat to melt the material or render it plastic, and displacing the molten or plastic material downwards and sidewise by pressure to form the bore hole walls, or removing it upwardly, or both. In Fig. 1, an electrode 3 is employed to form an arc, current being supplied by tubes 4 which also carry a cooling liquid ; the hole may be closed by a plug 5 which allows gaseous pressure to be applied under control. In another form, two electrodes are used, the arc between them being displaced downwardly by a magnetic field, or the arc may pass between the electrodes and a slag at the bottom of the hole. Alternatively, the heat may be applied by an electric resistance of tungsten &c., by the use of cooled coils to produce a high frequency alternating electromagnetic field to generate Foucault currents in the ground, or by a gas flame &c. and a current of gas may be forced against the bottom of the hole to displace the material. The heating device may carry a gauge collar, the diameter of which corresponds to the minimum diameter required in the borehole. Water or oxidizing or reducing substances may be admitted to the bore hole, or with electrical methods, scrapiron, mercury or other substance may be introduced. The material may be removed from the hole by evaporation, assisted by a current of air or gas or by use of an evacuated tube 13, Fig. 4, with a ball valve 16 and a fusible plug 15 which is dipped into the molten material. The bottom of a bore hole may be enlarged by use of the heating means.
