Title: Ground clearance warning system
Inventor: BURNS MAURICE R
IPC: G01S13/935
Filed: 1961-12-20
Abstract: 1,091,941. Pulse radar. NORTH AMERICAN AVIATION Inc. Dec. 20. 1961, No. 45707/61. Heading H4D. A monopulse radar system is mounted in a low-flying aircraft to provide the pilot with visual warning signals when ground obstacles are approached. An imaginary clearance plane is considered to be positioned at a predetermined distance beneath the craft and signals are produced when obstacles protrude above it. Three separate adjusting signal voltages are applied to the radar receiver; the first is manually controlled and corresponds with the perpendicular distance of the craft from the clearance plane, the second is inversely proportional to the square of the slant range to the obstacle and the third is inversely proportional to the slant range. The second signal voltage is applied to the radar receiver amplifiers to render the gain independent of the range. The third signal is combined with the antenna angle of depression and the clearance height to form a function which is multiplied by the radar receiver sum channel output signal. Ths is then compared with difference channel output to provide the warning C.R.T. signal. The mathematical basis of the system employs the property of a monopulse receiver, in that the ratio of the outputs from the difference and sum channels is proportional to the angle of the reflected signal from the antenna axis. The signals proportional to the inverse range and inverse range squared are derived from a phantastron circuit energized by the transmitter pulses.

Title: Electricity meters including a torque adjusting device
IPC: G01R11/22
Filed: 1974-10-23
Abstract: 1456612 Induction meters LGZ LANDIS & GYR ZUG AG 23 Oct 1974 [30 Oct 1973] 45773/74 Heading G1U The torque provided by the iron voltage core is adjusted by providing a shunt between the core and its flux return member, the shunt comprising two halves which move relative to each other, keeping the same spacing but changing their common overlapping surface area. As shown, a screw 5 in the return member 4 moves inside a sleeve 6 fixed to the core 1. The annular air-gap remains constant in width and the surface area common to both parts is dependent on the rotation of the screw 5. A projection 7 on the end of the screw saturates when close to the bottom of the sleeve 6 to further linearise the adjustment curve Fig. 2 (not shown) in that area. The sleeve 6 may not be completely cylindrical, but may have a flat lower surface (17), Figs. 3, 4 (not shown), two curved side arms (15, 16) and a flat top. The lower surface is bent up from one end of the sleeve base and the top and sides from the other end. The flat lower surface increases the surface of the voltage pole on core 1. The screw may be retained in position by a thermoplastic plug in a slot extending radially from the threaded hole in the member 4, Fig. 6 (not shown) or by a German silver leaf-spring Fig. 5 (not shown).

Optionally, perforations 20, made from the outer side of member 12, form burrs (26, Fig. 3, not shown) so that conductors 34 can be crimped inside member 12. Fig. 4 indicates how the connector can be used as a splice clip for splicing seven thick conductors 33, two thin conductors 34 and a stranded conductor 36. For satisfactory connections the distances A, B, C should be less than or equal to the sum of two diameters of the conductors to be connected. A plurality of splice clips may be connected together by frangible tabs in a strip form and used with a crimping machine.

Abstract: 1529569 Expanding pulley gear; changespeed control E F SALSBURY 19 Nov 1975 [20 Nov 1974 5 Nov 1975] 47624/75 Heading F2D  In a transmission comprising two expanding pulleys interconnected by a Vee belt the transmission ratio is varied by electrically energizable means which adjusts an axially movable half of one pulley relatively to the other half. In one embodiment comprising a driving pulley F, Fig. 2, on the output shaft 12 of an internal combustion engine C coupled by a belt 14 with a spring-loaded driven pulley H, a screw-and-nut actuator 76, 66 for adjusting the movable half F-2 is controlled by a photoelectronic system which causes the adjustment to be responsive to a comparison between the speed of the driving pulley and the spacing between its two halves in order to provide substantially constant torque at the driven pulley over part of the speed range of the engine, e.g. between 5,500 and 10,500 r.p.m. Affixed to a sleeve 26 of the movable pulley half is a strip M-1 of material having a pattern, shaped to suit the engine characteristics, of generally triangular sections of light-reflecting and non-light-reflecting areas N-1, O-1, Fig. 9, and a beam from a light-emitting diode 132 is reflected by the areas N-1 on to a photoconductive transistor U. The output from the transistor is amplified at 138 and converted to square-wave form by a Schmidt trigger 140, after which the circuit divides, one branch passing through a monostable multivibrator 142 and low-pass filter 144 to deliver a voltage B related to the speed of the pulley and the other branch passing through a low-pass filter 154 and inverter 156 to deliver a voltage A related to the position of the movable pulley half. These two voltages, of opposite polarity, are fed to a summer 158 and when they do not cancel each other a signal is fed via power buffer 160 to a linear actuator X consisting of a motor which, through a belt and pulleys, one of which is shown at 80, Fig. 2, rotates the screw 76 to adjust the movable pulley half. An hydraulic telemotor may be interposed between the screw and the movable pulley half. Alternative forms of actuator employ hysteresis and eddy-current brakes. In another embodiment a pulley on the output shaft of a constant speed electric motor is controlled to vary the transmission ratio in response to a manual command, means also being provided to prevent overloading of the motor. A further embodiment functions to provide a constant output speed from a transmission driven by a variable-speed prime mover.
