Title: Improvements in or relating to devices for radioelectric direction finding
IPC: G01S1/02
Filed: 1953-11-19
Abstract: 734,173. Radio navigation. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. Nov. 19, 1953 [Nov. 19, 1952], No. 32163/53. Class 40 (7). The invention relates to overlapping beam direction-finder equipment and receiving equipment for overlapping beam beacon arrangements wherein a reference direction is defined by the intersection of two equal amplitude lobes produced alternately for unequal periods. In such equipment means are provided comparing the signals received from each lobe to indicate the magnitude and sign of the angle between received signal direction and the reference direction. In a direction finder the aerial system may comprise a reflector 5 containing two primary elements coupled respectively to wave-guides 3 and 4 and capable of receiving on lobe patterns having one a maxima in the direction ox<SP>1</SP> and the other a maxima in the direction ox<SP>2</SP>; α1 is equal to α2, ox being the equisignal and reference direction. Waveguides 3 and 4 lead through switch devices 1 and 2 to guides 3<SP>1</SP> and 4<SP>1</SP> coupled to the receiver. Device 6 controls switches 1 and 2, which may be shunt connected non-oscillating magnetrons, so that only one of the guides 3 and 4 is connected to the receiver at any one time and the period of connection of one of the guides considerably exceeds that of the other. The ratio of the collection times is preferably between 1 : 2 and 1: 5. The output of the receiver fed by such a system, or the output of a radio beacon receiver, is fed to the indicator shown in Fig. 9. In this device the stepped waveform produced (assuming the signal and reference directions do not coincide) is fed through condenser 12 to remove the continuous current component and the positive component of the resultant waveform is passed by rectifier 13 and the negative component by rectifier 14. The signals passed are respectively fed to integrating circuits 15 and 16 and output resistors 18 and 19 in parallel. The difference between the output signals is applied to centre zero meter 17 which gives an indication of the magnitude and sense of the angle between the incoming signal direction and the reference direction. If a source of R.F. energy is coupled to the guides 31 and 41 the arrangement shown in Fig. 2 may be used as the beacon transmitter for co-operating with a receiver having an indicator as described above.

Abstract: 848,851. Writing instruments. SHEAFFER PEN CO., W. A. Oct. 23, 1956, No. 32320/56. Class 146(3). A reservoir pen has to the rear of a writing element 12 a rearwardly-vented reservoir 18 filled with capillary space-defining material 22 and having a filling tube 24 also filled with capillary material, the open forward end of which is movable to a position forward of the writing point 32 for filling purposes. The reservoir 18 is slidably mounted in a barrel 16 and a part 14 attached to the forward end thereof and is held against rotation by splines 40 formed on the inner surface of the part 14 which engage grooves 42 in an annular plug 44 that forms a closure for the front end of the reservoir 18. A sleeve 50 attached to a rotatable cap 46 at the rear end of the barrel 16 encloses the rear part of the reservoir 18 and a threaded portion 52 thereof engages a corresponding portion 54 of the reservoir, so that rotation of the cap 46, which is itself secured against axial movement, causes the reservoir to reciprocate in the barrel, its forward movement being assisted by a helical spring 56 compressed between a shoulder 57 in the barrel 16 and a loose collar 58 bearing against a shoulder 60 on the reservoir. The tube 24 extends through the part 14 and an axial bore in a feed-bar 26 to a point adjacent to the writing element 12, so that forward movement of the reservoir projects the end of the tube beyond the writing point 32. When this is done the reservoir is filled by capillary action when the open end of the tube is immersed in ink. The tube 24 also serves to convey ink from the reservoir 18 to the writing point 32 through slits 36, 34 and 30 all of capillary dimension in the parts 24, 26 and 12 respectively. The capillary material 22 may comprise spirally wound sheet material, suitably sized balls, tubes placed side by side, concentric tubes or convolutely wound corrugated material. Also the movement of the reservoir and tube in the barrel may be effected by a lever extending through the barrel and secured to the reservoir. Reference has been directed by the Comptroller to Specifications 646,726, 647,968 and 730,299.
