Abstract: 479,987. Piezo - electric crystals. STANDARD TELEPHONES & CABLES, Ltd. April 23, 1937, No. 11684. Convention date, June 12, 1936. [Class 40 (v)] A quartz crystal 1, is cut with its plane at an angle # of +35‹ to +60‹ (or -50‹ to -70‹) with the optic axis Z, and with its major axis 5 at an angle # of 45‹ with the X-axis, the ratio of the width w to the length l lying between 0À05 and 1À0. Preferably the ratio w/l is 0À875 when # is preferably +51À5‹. When # is -67À5‹, the ratio w/l is preferably 0À67. The Specification includes a curve relating frequency to # when # = 45‹, Fig. 6 (not shown); this is to be used in conjunction with curves relating change in frequency to change in temperature for #=38‹, 51¢‹ and 60‹, Fig. 7 (not shown) ; the ratio w/l is chosen from curves relating w/l to O, Fig. 8 (not shown). The frequency variation with temperature may be finally adjusted by reducing the width; this operation has little effect on frequency since this is mainly determined by the length. The frequency may be lowered by concaving either or both ends. British Specifications 479,637 and 479,979, and U.S.A. Specification 2,032,805 are referred to.

Abstract: 979,163. Mould closing in injection moulding machines. J. FACON. March 30, 1961 [March 31, 1960], No. 11718/61. Heading B5A. An injection moulding machine comprises two plates 8, 14 adapted to effect the closing of two halves 9, 12 of a mould, a front plate 11 forming part of the plate 14 is slidably mounted with respect to the axis of movement of the plate and at least one annular member 19 axially rigid with the front plate 11 but rotatable about an axis parallel to that of the plate, and elements 18, located between the plate 14 and the front plate 11 and co-operating with the member 19, the elements being normally inclined with respect to the axis of the machine, but being movable into positions parallel to this axis on rotation of the member 19 causing a considerable mould closing force to be applied to the halves 9, 12. The plate 8 is fixed though its position is adjustable using nuts 10, and the mould half 9 is connected to an injection cylinder 5 and hopper 6. The front plate 11 and the plate 14 are moved until the mould parts 9, 12 contact each other by an electric motor driving pinions (not shown) which engage with toothed racks, Fig. 9, fitted to four fixed supporting stays 4. The stays 4 are fitted with circular - and longitudinal grooves 13, 13a respectively, Fig. 9, and the plate 14 is fitted with nuts 21 adapted to be rotated by a worm 22, so that teeth 26 enter the grooves 13 to lock the plate 14 to the stays 4. Final closure of the mould is effected by movement of the front plate 11 away from the locked plate 14 by rotation of the annular member 19 which runs on ball bearings 20. Depressions 26 are provided in the plate 14 and member 19 to accommodate the rounded ends of the elements 18. Rotation of the member 19 and the nut and rotating screw 24, so that the member 19 is moved in the direction F in Fig. 5, causes the front plate 11 to move slightly away from the plate 14 under a considerable pressure. Alternatively, the member 19 may be disposed between two rows of elements 18 one row engaging with the plate 14 and the other with the plate 11 (Fig. 6a, not shown). Also, in larger machines (Fig. 10, not shown), the plate 14 may be moved by an electric motor on the base of the machine, the stays 4 being used only as guide rods, and two members 19<SP>1</SP>, Fig. 11, may be provided to coact with elements 18<SP>1</SP>, the members 19<SP>1</SP> being rotated through a small angle by rotation of a pinion 46 engaging with a toothed rack 45 fixed to a shaft 41, to move levers 41, 43, 44 to the dotted line positions shown in Fig. 11. Simultaneous rotation of the members 19<SP>1</SP> is ensured by a peg 42.

Title: Flow meter circuits including a.c. induction flow meters
IPC: G01F1/60
Filed: 1953-04-30
Abstract: 726,013. Electric indicating systems. T.O.B.I., N. V. April 30, 1953 [May 2, 1952], No. 12020/53. Class 40 (1). An amplifier for an a.c. induction flow meter comprises a negative feed back circuit arranged to compensate for changes in amplitude and frequency of the power supply for the flow meter. The latter is of the type in which the liquid flows perpendicular to an alternating field produced by an electromagnet and electrodes are arranged in the fluid to pick up an induced alternating e.m.f. in a direction perpendicular to both the field and the direction of flow. In this arrangement the field strength of the magnet varies directly as the amplitude of the energizing voltage and inversely as the frequency thereof, the output e.m.f. being correspondingly affected. In a negative feed-back circuit for an amplifier for compensating for the above errors the amplifier output is fed to the potentiometer 19 ... 21 a tapping from which feeds the inductance 9 in series with the resistance 7, the impedance of the former being much greater than the latter. As the frequency increases the current through the resistor 7 decreases thereby reducing the amount of feed-back to the first stage 8 of the amplifier. The a.c. supplying the flow meter electromagnet is also rectified at 15 and after smoothing is fed to a second winding of the inductance 10. Increase in current drives the working point of the transformer 9 to a different point on the hysteresis loop thereby decreasing the inductance to increase the amount of negative feed-back. If the same supply voltage is used both for the amplifier and the electromagnet the d.c. for the coil 10 may be obtained from the power pack of the amplifier.

Abstract: 1430625 Selective absorption of gases ENTREPRISE DE RECHERCHES ET D'ACTIVITIES PETROLIERES 14 March 1973 [14 March 1972] 12329/73 Heading B1L With valves 8 and 9 closed, air is fed through inlet 5 to the thin layer of selective absorbent 4 which has a thickness which is not greater than the diameter of a circle of the same area as either of the surfaces of the layer and either nitrogen or oxygen is selectively absorbed depending upon the absorbent chosen. When a predetermined pressure has been reached after a preset time the clock 12 closes valve 6 and opens valve 8 so that the less sorbable component can be discharged through pipe 10. When the pressure inside the container drops below a given level valve 8 is shut and valve 9 is opened to allow the more sorbable component to be evacuated by lowering the pressure or raising the temperature. When the pressure has dropped to a predetermined level valve 9 is closed valve 6 is opened and the cycle repeated. A number of different ways of achieving a thin layer of absorbent are described in relation to Figures 2-6 (not shown). Thus the surface of the layer may be circular or rectangular. The layers may be vertical or horizontal and may be combined to give series or parallel flow of gas through the absorbent. The absorbent may be confined .between two cylindrical surfaces or between a series of inlet and outlet tubes.
