Title: Current selection and limiting circuits
IPC: G01R19/00
Filed: 1967-10-25
Abstract: 1,139,626. Controlling the selection of sources. FOXBORO CO. 25 Oct., 1967 [27 Oct., 1966], No. 48628/67. Heading H2H. A circuit having current sources 20-23 supplying a load across terminals 26, 27 has diodes 20C-23C to select the source having the highest magnitude, the step transition between the sources due to the forward and backward threshold diode voltages being compensated by a corresponding voltage across resistor 28. At any time, one diode is forward biased and the remainder back biased hence a voltage equal to the difference between the biasing voltages-about 1 volt-is generated by a reverse current flow through resistor 28. A constant reference point 35 is established by diodes 43-48 preferably of similar type and carrying similar current to diodes 20C &c. which similarity provides temperature compensation: Two diodes e.g. 43, 44 provide a bias of 1 volt to compensate for the difference in threshold voltages and the remainder, about two volts, to compensate for the volt drops across resistor 31 and amplifying transistors 29, 30, the latter regulating current in opposition to the source current to maintain the resistor 28 voltage at 1 volt. The circuit may be adapted to select the lowest current source by reversing the polarity of diodes 20C-23C and altering the point 35 voltage by removing four diodes 45-48. In a modification, the arrangement may select the median of a plurality of sources by replacing the diodes 20C &c. by Zener diodes of the same polarity and adjusting the bias at point 35 appropriately. This circuit may be further modified (Fig. 3, not shown), by providing fixed high and low current sources across diodes (51), (52) so that when the current from a source (50) is between these values it is unregulated but when it passes the values set by the high or low sources, it is clamped at this value. A transistor (55) supplies the low current and another transistor (56) supplies the difference between the low and high values, these currents being passed through resistor (62) and diode (63). Surplus of source (50) current above the low value is passed through diode (51) and any surplus above the high value is passed back through diode (52).

Abstract: 1454368 Radar EMI Ltd 10 Jan 1974 [31 Oct 1972] 50089/72 Heading H4D In a synthetic aperture radar system means are provided for cancelling the effect of crosstrack, drift or aerial misalignment along the direction of motion in the processing of the received signals, the means comprising an aerial having two spatially separated phase centres. As the aerial moved forward, the signals corresponding to one position of the first phase centre are stored and when the second phase centre reaches the same position signals corresponding to the centre are stored. The two sets of stored signals are subtracted and the subtraction gives ##, the phase difference in the stored signals due to drift, ##=4#vt/# where v=drift velocity, t = time between the phase centres being at the same position and # = wavelength. The frequency required to offset the drift movement is given by f = ##/2#t. An apparent drift motion could be caused by the aerial axis not being parallel to the direction of motion. If the aerial platform is moving at velocity V and the angle of the aerial axis to the direction of motion is # then the resulting doppler frequency is given by f=2V sin #/# and as f = ##/2#t then equating ##/2#t = 2V sin #/# gives # so that the aerial may be aligned with the direction of motion.

Title: Hot Air Bomb, or Internal Combustion Boiler, particularly for Producing Underwater Bubbles, for use, especially, in Polar Regions
Inventor: PEDRICK ARTHUR PAUL
IPC: F22B1/26
Filed: 1968-10-25
Abstract: 1,175,916. Combustion chambers operating under pressure. A.P. PEDRICK. Oct. 25, 1968, No.50646/68. Heading F1L. The invention relates to a device for generating an intermittent discharge of hot air or gas such that when the device is immersed in water the hot air or gas discharges from the device in the form. of bubbles which in rising through the water result in the water being heated. In one form the device comprises a spherical outer casing with a central tubular combustion chamber arranged vertically therein, the combustion chamber having a spring- loaded outlet valve. The casing is partly filled with liquid fuel and air or oxygen under pressure is charged into the space above the fuel, the fuel and air discharging through small bores into the combustion chamber where they are ignited. When the pressure within the chamber rises to a predetermined value the outlet valve opens and a charge of combustion gas with possibly unburned fuel discharges into the water in the form of a bubble which rises to the water surface thus heating the water. The unburned fuel may continue to burn as the bubble rises through the water. The process is repeated until the fuel and air are consumed. The device may be placed in a kettle of water. Another application is stated to be for melting a channel through ice in the North Polar region whereby a sea route may be created across the Polar ice cap. An arrangement by which combustion gas generated in accordance with the invention may be dropped from aircraft on to the ice surface is described, the arrangement comprising a device which melts a hole through the ice through which the combustion gas generator is then lowered, the gas generator commencing operation when it enters the water below the ice, the bubbles of combustion gas heating the undersurface of the ice which is thus melted. In place of a combustion device a nuclear device may be used.

Abstract: 1291456 Automatic speed control MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 15 Oct 1969 [29 Oct 1968 30 Oct 1968 and 20 Nov 1968] 50768/69 Heading G3R Magnetic recording and reproducing apparatus comprises a magnetic lead 3 on which is impressed one field of a television signal for an interlaced scanning system, a disc-shaped magnetic recording medium 1 rotatable by a motor 2 to record the signal in the form of an annular track which may be repeatedly reproduced to provide a static image signal, a disc 4 rotatable by a motor 6 through an idler 7 and a control system for the motor 2 consisting of a comparator 10 which compares the phase of the output signal of a circuit 12 for separating the vertical synchronizing signal from the television signal applied at terminal 11 with the phase of the output signal of a detecting lead 8 which is carried by the disc 4 and emits a pulse signal when close to a magnet 9 carried by the disc 1. The motor 2 is controlled to maintain a predetermined phase relation between the rotation of the disc 1 and the vertical synchronising signal, whilst the angular speed of rotation of the disc 4 is chosen to prevent, during every rotation or reproduction of every field, the disturbance of the horizontal synchronizing signals and distortion of the reproduced image resulting from the lag equivalent to a half of the horizontal synchronizing signal. It is shown that this object may be achieved by making the angular speed of the disc 4 equal to 1/2 WsTH/TV (2n + 1) rad/sec. where W s  is the angular speed of the disc 1, TH is the period of the horizontal synchronizing signal, TV is the period of the vertical synchronizing signal and n is a positive integer. Accordingly the speed of the motor 6 and the diameters of the idler 7 and disc 4 are selected so that the above equation is satisfied. A discussion is given of the period of rotation of the disc 1 required to satisfy this equation according to whether the disc 4 is rotated in the same or the opposite direction relative to the direction of rotation of the disc 1. Typical results produced by these two conditions are explained with reference to an annular track, Fig. 2 (not shown) which will possess an unrecorded blank or a portion of dual recording according to which condition occurs. Such defects are minimized by making the value of n sufficiently small. Members 8, 9 may be replaced by a combination of a light source and a photo-electric element. The invention may be applied to a cylindrical magnetic recording medium. In two other embodiments using a disc-shaped recording medium, the member 8 is stationary and the magnetic head 3 is carried by a directly-driven disc (16) equivalent to disc 4, Fig. 3 (not shown) or the recording medium is fixed and the magnetic head (20) is carried by a disc (22) driven by the motor controlled by the phase comparator, the disc (23) equivalent to the disc 4 being indirectly driven and carrying a detecting head (25) co-operating with a magnet (24) carried by the disc (22), Fig. 4 (not shown).
