Title: Improvements relating to radar receivers
Inventor: BRADSELL PETER
IPC: G01S13/95
Filed: 1959-10-20
Abstract: 894,974. Radar; non-linear circuits. COSSOR Ltd., A.C. Aug. 8, 1960 [Oct. 20, 1959], No. 35573/59. Classes 40(6) and 40(7). Relates to a superheterodyne radar receiver for a weather radar having an output/input amplitude characteristic which increases up to a turnover point X and then decreases to zero, e.g. as shown in Fig. 1a, so that a storm region is shown on a P.P.I. display as a bright patch with an inner dark patch corresponding to the most violent storm area. According to the present invention the I.F. stage is split into two separate amplifying channels coupled to respective detectors whose outputs are combined in opposition and the output/input characteristic of each channel is logarithmic, the slopes of the two characteristics being different and the threshold of the steeper characteristic being delayed relative to the other characteristic, e.g. as shown in Fig. lb. As shown in Fig. 2 each channel comprises a separate logarithmic amplifier 15, 17 having respective amplitude characteristics I and II, Fig. 1b, the delayed threshold of the amplifier 15 being controlled by a variable attenuator 14. If the threshold for the characteristic I of the amplifier 15 is displaced to the right beyond the point at which the amplifier 17 saturates then the resultant characteristic will have a flat top Fig. 5 (not shown). In another embodiment Fig. 3, one channel comprises a first amplifier 19 coupled to a detector 16 and the other channel comprises the first amplifier 19 in series with a second amplifier 20 and detector 18. The actual arrangement may be as shown in Fig. 4 when the amplifiers A, B, C and D, E, F correspond to amplifiers 19 and 20 respectively and the groups of detectors 21 and 22 correspond to detectors 16 and 18 respectively. Each of the stages A to F comprises a linear amplifier with a predetermined saturation level so that as the input increases stage F saturates first, then stage E and so on to give an overall logarithmic characteristic, the combined output from the detector 21 being negligible until the stage D saturates when the resultant output from the combining circuit 13 starts to decrease. The amplifiers 15 and 17 in Fig. 2 may be of the type shown in Fig. 4.

Title: Method and apparatus for providing space security
IPC: G08B13/16
Filed: 1973-07-30
Abstract: 1420043 Intruder alarms FASERUND KUNSTSTOFF-PRESSWERK ROMEN KG 30 July 1973 [31 July 1972] 36228/73 Heading G4N [Also in Division H4] A method of providing protection for a space 15, e.g. rooms, cars, containers, comprises the steps of generating at 14 an inaudible infrasonic or audio pressure wave field to substantially fill the space, sensing the field at 16 for triggering an alarm 24 when an alteration of the confines of the space 15, e.g. by the opening of a door or a window affects the pressure wave field. A device for implementing the above method includes a generator 11 and a loudspeaker 14 for setting up a standing wave pattern in the space 15 at an infra-sonic frequency corresponding to the natural resonant frequency of the space. An opening of a door or a window alters the above frequency and hence the phase, amplitude or frequency of sound received by microphone 16. The received signal is compared with the direct signal received via a variable resistor 16 at a difference amplifier 20 and the difference output is applied via a switch 22 to an alarm unit 24. The switch 22 may be controlled by a timer (not shown) or by a generator 23 responsive to cipher coded radio signals from a generator 25 operated by an authorized person. The loudspeaker 14 may also be used as the receiving transducer (Figs. 4, 5, not shown). The output of amplifier 18 may be fed back to the input of amplifier 12 to form oscillations at the required frequency and the generator 11 may be left out (Figs. 3, 5, not shown). Several rooms may be acoustically coupled so that the speaker and microphone may be kept in different rooms. Sounds may also be radiated at different frequencies along different axes within the same enclosure to deceive an intruder. The radiated sound may also be modulated.

Abstract: 345,988. Thermometers. SLOUGH, F. M., 602, B.F. Keith Building, Cleveland, Ohio, U.S.A. Nov. 30, 1929, No. 36800. Convention date, Nov. 30, 1928. [Class 97 (iii).] A device for the remote indication of temperature comprises two bimetallic strips 23, 24, both subjected to the temperature to be measured, and arranged so that the strip 24 bends more than the strip 23 as their common temperature rises. The approach of the strip 24 to the strip 23 causes a circuit to be completed between contacts 22, 21 to allow current to pass through a heating element 19 surrounding the strip 23 so that the temperature of the latter is raised until the strip bends sufficiently to break the circuit. The current which passes through the coil 19 also passes through a coil 10 at the remote indicator, this coil being arranged to heat a bimetallic strip 11, the consequent bending of which causes movement of a pointer 8. An unheated bimetallic strip 12 may be interposed between the strip 11 and the pointer to compensate for variations in atmospheric temperature. The device is particularly intended for indicating the temperature of the cooling water of an automobile engine, the strips 23, 24 being mounted in a container 6 projecting into the waterjacket 3; while the indicator may be mounted on the dashboard.

[Class 143.] Vehicles, ascertaining distribution of weight on wheels of.-Relates to the type of machine arranged to measure the braking effect applied to a road wheel and the load applied on to the ground by the same wheel, and consists in using the same frictional driving device to determine the braking effect and also to ascertain the load on the wheel. The cradle is formed by two spaced and braced members 1, 1a the upper edges of which are circular and which support rollers 7, 7a, 8, 8a which may be curved to the shape of the tyre and which may be ribbed. At one end the cradle is formed with a box 3 in which is a shaft 13 to which is keyed a worm wheel 15 in mesh with a worm 17 adapted to slide on a squared shaft 18. The worm is mounted in a two-part box 17 which slides with a worm, flanges 25, 25a being guided on rods 26 while springs 35, 36, 35a, 36a are arranged between the flanges and cross bearers of the frame. A two-armed lever is mounted on a pivot 30 and has pivoted to its ends rods 27, 27a which pass freely through the flanges 25, 25a and are provided with stops 37, 37a. The lever point is provided with an indicating pointer 31 the end of which is bent upwards and passes through a curved slot so as to move over a scale provided on the top of the casing. A chain 11 passes over sprockets on the spindles of rollers 7, 7a and over a sprocket on the spindle 13. In use the apparatus is placed under a vehicle wheel and the spindle 18 rotated by a handle applied to the end 23. The rollers will try to turn the wheel and the resistance experienced which is proportional to that portion of the weight of the vehicle and load borne by the wheel will be transmitted, the worm moving against its springs until such resistance is balanced. The usual practice is to put the brake at half stroke and then measure the additional resistance which should be equal to that due to the weight and load borne by the wheel.
