Abstract: 1,233,683. Magnetic recording and playback. INTERNATIONAL BUSINESS MACHINES CORP. 19 Dec., 1969 [15 Jan., 1969], No. 61994/69. Heading G5R. A first magnetic record medium 10 carrying a plurality of parallel recorded tracks is moved together with a second magnetic record medium 20 past a magnetic bias head 30 having a gap by means of which a magnetic field is applied to a selected one of the parallel tracks 10a in a direction transverse thereto so that the information recorded therein is re-recorded along a single track 20a on the second record medium 20 which is then played back, as it moves away from the bias head 30, by a reading head 50. The two record media, tapes as shown, are pressed together pneumatically at the bias head 30 which is movable to vary the selection from the parallel tracks.

In a marine seismic source a liquid or gaseous mixture is exploded in combustion chamber 8 to drive piston 5 forward in cylinder 1, thereby moving plate 7 away from plate 2 to create a pulse in the water as water fills the rarefaction between the plates. Components of the mixture are injected under pressure into chamber 8 by devices 11, 12, and are ignited by sparker 13. Combustion products are vented through ports 15 (when the piston 5 has moved forward) to chamber 15a and exhaust pipe 15b (which may have a valve to prevent ingress of water). Compressed air is injected at 19 to return piston 5 to its initial position and hold it there while the explosive mixture is injected. The air or fuel supply to the combustion chamber may be used for scavenging combustion products.

Abstract: 1290947 Spray carburetters SOC INDUSTRIELLE DE BREVETS ET D'ETUDES 26 Feb 1970 [3 March 1969 30 Sept 1969] 9411/70 Heading F1B In a carburetter having main and idling systems opening to the induction passage 1, the passage 12 supplying the idling orifice 4 is fed with fuel and air through respective calibrated orifices 7 and 9 and the flow through the passage to the orifice 4 is adjustable by a throttle needle 17. The flow of mixture from the passage 12 to an orifice 22, through a passage 19 by-passing the throttled idling orifice 4, is controlled by a valve 23 operated by a diaphragm 21 which may be subjected to the vacuum downstream of the throttle valve 3 through passages 25 and 26 under the control of a valve 28. When the valve 28 is closed the disphram 21 is subjected to the pressure at orifice 29 which, when the throttle valve 3 is in its idling position, is substantially atmospheric. The valve 28 is operated by a diaphragm 31, or capsule (39), Figs. 2 and 3 (not shown), subjected to the vacuum in the chamber 30 connected to the passage 26. The opening point of the passage 26 into the induction passage 1 is downstream of the throttle valve 3 when the valve is in its minimum open idling position and is upstream of the valve when the valve is opened slightly and therefore provides for opening of the valve 28 only during deceleration with minimum throttle opening. The diaphragm 31 is subjected to atmospheric pressure on the side opposite the chamber 30 through a port 38. To reduce the effect of atmospheric pressure changes on the operation of valve 28, the valve is operated by an evacuated capsule (39) Fig. 2 (not shown), containing a spring, and located in the chamber 30 for axial manual adjustment by a screw (35a). To eliminate the effect of atmospheric pressure changes, the capsule adjusting screw (35a), Fig. 3 (not shown), is adjustable in a member (40) supported from the capsule chamber wall by a metallic bellows (42) or a diaphragm which is subjected on one side to the capsule operating pressure and on the other side to atmospheric pressure. Progression orifices 5 and a further restricted orifice 14 are fed with fuel and air through respective calibrated orifices 8 and 10.

Abstract: 1296723 Measuring drift of a gyrocompass TELDIX GmbH 24 Aug 1970 [23 Aug 1969] 40684/70 Heading G4H Apparatus for determining the drift of a gyrocompass includes means for measuring, when the gyro carrier is stationary,.the angle α between the frame carrying the gyro rotor and a reference direction at N equal intervals and either, if α is initially zero, adding the results, of these measurements or, if α=α 0 #0 adding, the measurements during the interval [0, T/2] and then subtracting from this sum the measurements made during the interval [T/2, T] to derive a signal proportional to the drift. In the embodiment of Fig. 3 sine and cosine values of the angle α 0  between the spin axis of the gyroscope and the longitudinal axis of the craft 1 on which the gyrocompass is mounted are obtained from a pick-off and converted in network 2 to two cyclic signals, the relative phase of which represents the angle α 0 . Negative going zero crossings of these signals are used to open and close gate 4 so that for each cycle of the signals a number of pulses representing the instantaneous value of the angle is fed to a counter 6. The count is compared with the previous measured value and, in order to prevent errors, only fed to a binary register 10 if it is identical to the previous count. Successive counts in register 10 are accumulated in a regisster 11 additively for the time interval [0, T/2] and subtractively for the time [T/2, T] so that the result represents the area TD/4 of the parallelogram F 2  of Fig. 2, i.e. it is proportional to the drift D. The register 11 need only have enough places to store the maximum possible drift since higher value places will cancel out during the addition and subtraction. To measure the drift when the angle α 0  is near 0 or 360 degrees, enabling of the gate 4 may be lengthened or shortened by an interval representing 180 degrees. The count in register 11 is transferred at the end of the measurement to register 12 and may be converted to a duration by pulsing a counter 13 a gate 16 being enabled at a full count of the counter and closed at equality of the count and contents of register 12.

As the carriage transverses in the direction of the arms A a winch drum 13 rotates and a hose reel 14, supplying fluid to the jets 30, unwinds. The drum 13 is geared down to a shaft 22 by gearing means 23, such that the programming means which is formed by a disc 25 mounted on the shaft 22 rotates once during a complete traverse. The disc 25 is provided with peripheral protuberances 27, which, as the disc rotates, trip the arm of a switch 18, which in turn steps a rotary switch 17, thus changing a signal voltage. This signal voltage is compared by an electromagnetic induction coupling 16 with a reference voltage from a tachogenerator driven from the coupling output, variations in the difference between said voltages determining the torque applied to the winch 11 and thus the carriage speed. The length of time a speed is maintained is dependent on the separation of the protuberances 27. To allow for different vehicle models, various discs which are readily interchangeable are used, these discs differing in the number and separation of the protuberances. The carriage can be stopped for a predetermined time, using a time delay device, after which a positive output, sufficient to restart the drive, is supplied. On the return traverse the carriage is hauled by the hose reel 14 and winch drum 13 driven by a motor 32, the carriage moving at a constant speed. Alternatively the apparatus may be modified such that the return traverse is also at variable speed.

The embodiment shown comprises a sleeve 10 of elastomeric material sealed at its ends to detachable parts 12 and 14 of fitting 11, which are interconnected so as to allow longitudinal motion but no rotational movement between them. A bore 6, in connector 2, and a passage 27 in the fitting 11 allow the sleeve 10 to be inflated to effect sealing of the drying tank 44. Valve 7 closes the bore 6 at the end of the connector 2. The coupling 20 is arranged so that when a tension is applied to the shackle 39, via the withdrawal line, the shear pin 40 is fractured and, the nose plate 38 pivots about a socket screw 37 and strikes a plunger 36 which is slidably mounted in bore 31, and, which operates the valve 7 causing it to open to deflate the sleeve 10.
