Patent GB-1040576-A (GB)
Title: Measuring apparatus
Inventor: MUDIE JOHN DAVID
IPC: G01R33/022
Filed: 1962-07-27
Abstract: 1,040,576. Selective signalling. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Oct. 28, 1963 [July 27, 1962], No. 29018/62. Heading G4H. [Also in Division G1] Apparatus for measuring the frequency difference between two electric pulse trains comprises means for additively measuring two time intervals, the first interval being the time difference between a pulse in one channel and a predetermined pulse thereafter in the other channel and the other interval being the time difference between a predetermined subsequent pulse in the second channel and a predetermined pulse thereafter in the first channel, whereby the total time measured is a function of the two frequencies from which, if one of the frequencies is known, the difference may be calculated. The two time intervals are measured by counting clockpulses and the system described is particularly applicable to measuring the difference in the earth's magnetic field at two neighbouring points by measuring the difference in frequency between two pulse trains produced by two gyromagnetic magnetometers, which pulse trains have a random phase relationship and which difference is small relative to either of the frequencies. The basic arrangement, Fig. 1, comprises a counter A with capacity M, a counter B with capacity M-X, and a counter C for counting clock-pulses from a generator 6. Initially counter A is set to about ¢M, counter B is set to - 1 and gates 5 and 7 are closed. In operation pulses from the first magnetometer pass direct to counter A. When counter A is full, and resets to zero, gates 5 and 7 are opened and clock-pulses start passing to counter C. The initial period while counter A is counting from ¢M to M is introduced to give the system time to settle down. When the first pulse from the second magnetometer arrives after the opening of gate 5 counter B passes to zero and closes gate 8. This terminates the first time interval. Counting continues in both counters A and B however and when counter B becomes full (= M-X) and rests to zero it opens gate 8. This marks the beginning of the second time interval which continues until counter A becomes full (=M) whereupon gate 7 is closed to terminate the second time period. The Specification shows that the final count in counter C is approximately proportional to where H is the earth's magnetic field and Ha is the spatial anomaly (i.e. the field difference at the two measuring points). Thus if gamma, H, X and M are known HA can be calculated. Suitable valves for M and X are 1,000 and 3 respectively and the clock-frequency could be 100 kc/s. Two modifications are described, and in one (Fig. 2, not shown), one magnetometer can be switched out of circuit and the arrangement can be used for measuring one of the frequencies, i.e. for measuring H.

Abstract: 427,119. Tripods. HENLEY'S TELEGRAPH WORKS CO., Ltd., W. T., and MAYLETT, A. M. E., 11, Holborn Viaduct, London. Oct. 21, 1933, No. 29185. [Class 52 (v)] In a collapsable tripod of the type comprising a pair of front legs 1, 2 pivotally connected and passing through a sleeve 6 to which a rear leg 3 is also pivoted, the pivot 9 between the front legs is such as to permit relative longitudinal movement of these legs to lock them together in the closed position, and the parts are so connected that when closed the rear leg is constrained to lie alongside the front legs. The sleeve 6 is of sector shape and carries the pivot pin 9 which engages a hole in the leg 1 and a slot 5 in the leg 2 so that by raising the leg 2 in the closed position a projection 12 at its upper end may be caused to engage a slot 13 in the upper end of the leg 1 thus locking the legs together. Internal projections or stops 10, 11 in the sleeve prevent movement of each leg beyond its central position so that when locked together the legs cannot move relatively to the sleeve. To maintain the effective lengths of the front legs equal, the pivot pin 9 is kept in the upper end of the slot 5 in the open position by a pin 14 on the leg 2 engaging an L-shaped slot 15 in the sleeve. Alternatively, the leg 1 may be furnished with the stud 12 and the leg 2 with the slot 13, disengagement being effected by sliding the leg 2 downwardly. The rear wall 8 of the sleeve is slotted and provided with a pair of rearwardly directed lugs 17 carrying the pivot pin 18 for the rear leg 3, and the head 19 of the pivot pin 9 is also slotted so that in the closed position the rear leg bears closely against the front legs and cannot rock. In the open position shown the top of the rear leg passes between the upper ends of the front legs. The rear leg may be cut away to clear the sleeve.

Abstract: 956,574. Cutting by spark discharges. K. INOUE. Aug. 29, 1960 [Aug. 27, 1959 (3); Sept. 3, 1959], No. 29701/60. Heading B3V. A spark discharge circuit comprises a condenser and a resonant circuit connected across the spark gap to provide respectively a main discharge and subsequent subsidiary discharge. During manual working each main discharge forms a crater having a peripheral ridge which short circuits the gap between the electrode 2 and the workpiece 3 and the subsidiary discharge removes the ridge. A condenser 4, Fig. 1, providing the main discharge is supplied from an A.C. source la through a rectifier le and an inductor 5 which acts as a filter. A saturable reactor 1c in series with the A.C. source la has a control winding connected to the output of the rectifier 1e and serves to reduce the input voltage when a short circuit occurs. The subsidiary discharge in the form of a high frequency pulsation is derived from a series resonant circuit 6. Alternatively a parallel resonant circuit or a resonant circuit consisting of a series or parallel circuit inductively coupled to a loop circuit may be used. The values of the components of the resonant circuit may be adjustable to permit variation of the timing or duration of the subsidiary discharge to suit the workpiece material or the operation. In a moditication, Fig. 9, a number of series or parallel resonant circuits of different resonant frequencies are connected in parallel to provide a subsidiary discharge in the form of a square waveform pulse which goes negative as the main discharge ends. In a further modification one of a number of resonant circuits of different resonant frequencies is selected by a switch.

Title: Method and apparatus for volume measurement
Inventor: KENG EDWARD V H
IPC: G01F17/00
Filed: 1969-06-12
Abstract: 1,220,313. Measuring volume. GEORGIA TECH RESEARCH INSTITUTE. June 12, 1969, No. 29769/69. Heading G1X. Apparatus for determining the volume of irregular bodies comprises a sealable system having a reference compartment 12 with a lid 16 through which a body under test may be introduced into the system, a valve 42 for establishing a predetermined constant gas pressure within the system e.g. by connection to a source of air at constant pressure, or to a source of inert gas such as helium, a pump 20 with a movable piston for varying the volume of the system and thus the gas pressure therein, a pressure detection mechanism 50 for recognizing the attainment of a known pressure in the system by operation of the pump, and an indicator e.g. a revolution counter 40 attached to the pump 20 to indicate the increase or decrease in volume to the presence or otherwise of the body under test in the compartment 12. The piston 26 comprises a nut member 34 co-operating with a screw 30 rotatable by a handwheel 38 to move the piston, and the pressure detection mechanism 50 includes a closed chamber containing a bellows which expands and contracts with pressure changes in the chamber and the movable end of which carries a contact closing the circuit to a lamp 82 on attainment of the known pressure in the system. In use with the lid 16 in place, the valve 42 is operated to fill the system with air at the predetermined pressure which may be atmospheric, the valve then being closed to seal the system. The piston is then moved to reduce the pressure allowing the bellows in the mechanism 50 to expand and close the circuit to the lamp 82. The reading on the counter 40 is then noted, and the process is repeated with the test body in place in the compartment 12. If the test body absorbs air then helium may be used after evacuation of the system by moving the valve 42 to connect with a vacuum pump. The difference in the readings of the counter 40 gives a measure of the volume of the test body related to the predetermined gas pressure at which the system was filled. If the system is calibrated using a body of known volume then it is not necessary to know the original predetermined pressure. The apparatus may also be used to determine the amount of gas absorbed by a test body by first measuring its volume using helium, which will not be absorbed and then repeating the measuring procedure using air or other gas which is absorbed. The apparatus may be modified by connecting the piping 52 leading to the mechanism 50 to the interior of the bellows. In this arrangement the pump 20 is used to increase the pressure in the system each time until the lamp 82 is illuminated.
