Title: Improvements in or relating to radiogoniometers
IPC: G01S1/02
Filed: 1925-11-19
Abstract: 243,372. Bellini, E. Nov. 20, 1924, [Convention date]. Directive signal ling. - In order to secure a true zero point of reception ir radiogoniometers o Bellini - Tosi type when working on continuous-wave transmission, the receiving loops are connected across the diagonals of a Wheatstone-bridge arrangement, the arms of which comprise four tuning condensers C1 - - C4, preferably mechanically coupled together. In this way a more exact difference in tuning can be obtained, the small differences in capacity between different condensers being balanced out. The two fixed frames shown in Fig. 1 are inserted for example between the points A, B and C, D respectively in Fig. 2. Or balancing inductances may be combined with the tuning condensers. As shown in Fig. 4, these inductances are in the form of a closed toroidal winding arranged in. parallel with the condensers C1 - - C4. The magnetic interaction between the different parts of the winding tend to equalize the currents in diametrically opposite arms, and thus improve the desired balance.

Title: Measurement of length of magnetisable objects
Inventor: LEE EDWIN CHARLES
IPC: G01B7/04
Filed: 1958-09-12
Abstract: 879,550. Measuring continuous lengths. STANDARD TELEPHONES & CABLES Ltd. Sept. 11, 1959 [Sept. 12, 1958], No. 29257/58. Class 106 (2). In a method of measuring and indicating the length and position of a longitudinally extending member 3 a succession of consequent magnetic poles disposed at intervals of uniform length are impressed upon the member 3 and the positions of the poles are subsequently indicated by a play-back head, the indications of the play-back head being independent of any relative velocity between the member 3 and the play-back head. Fig. 1 shows a steel hawser 3 and a recording head having an ironcored solenoid 1 and pole pieces 2 spaced six inches apart. The hawser 3 is moved six inches at a time, and the direction of the current through the solenoid 1 is reversed at each step, thus forming consequent magnetic poles. To measure the length of the hawser it is passed in front of a play-back head, Fig. 2, to the primary winding 6 of which a 5 kc/sec. tone is applied.. No current is induced in the secondary winding 8 unless an axial external magnetic field acts on the play-back head, in which case a second harmonic tone of 10 kc/sec. will be induced in the winding 8. This winding is connected to a valve voltmeter 10, an oscilloscope or any other suitable indicating or counting instrument to determine the total number of poles which have passed the head, and the position of the last one relative to the head. It is stated that the induced current is unaffected by changes in the speed of the hawser. Specification 856,069 is referred to.

Abstract: 450,594. Electrical treatment of water. PIERPOINT, A. J., and CROUCH, R. H., 43, Whitcomb Street, London. Oct. 15, 1934, No. 29508. [Class 41] Water is treated by the passage of alternating current of density between 0À2 and 3À4 microamperes per square inch measured at the surface of a working electrode ; when water so treated is evaporated hardness - forming impurities are precipitated as mud instead of as a hard scale. Preferably all the water treated is caused to flow in close proximity to the working electrode. In the apparatus shown, water is fed to a receptacle 11 from which it passes to the outer tank 1 through tubes 6 perforated at their lower ends inside which electrodes are mounted centrally. The tank 1 is connected to one pole of the alternating current supply. In a modification treatment is effected in two stages the water being first fed to an inner compartment of the receptacle 11 and passing therefrom to the outer compartment through electrode-containing tubes similar to 6. The number and dimensions of the electrodes depends on the volume of water to be treated. In a modified apparatus adapted to be inserted in a pipe line the electrodes consist of sheets forming baffles and are separated by insulating baffles. Regulation of the current is preferably effected by means of a set of removable strip condensers each of small value. The circuit should also include a fuse and a circuit breaker.

Title: Improvements in or relating to radio navigation aids
Inventor: JOLLIFFE SIDNEY ARTHUR WALTER
IPC: G01S1/30
Filed: 1959-08-31
Abstract: 889,780. Radio navigation. MARCONI'S WIRELESS TELEGRAPH CO. Ltd. March 10, 1960 [Aug. 31, 1959], No. 29625/59. Class 40(7). Relates to a Doppler radio navigation system for determining on an aircraft the ground velocity vector of the craft when the position of the craft is known so that if an initial position of the craft is known, its position thereafter may be continuously computed by dead reckoning. If three different frequencies F A , F B  and F C  are transmitted respectively from three spaced transmitters A. B, C, Fig. 1, of known location then the corresponding frequencies received at a craft X travelling at a velocity V indicated by the vector ABC will be F A  + dF A , F B  + dF B  and F C  + dF C  where dF A  is the Doppler frequency component due to the component v A  of V in the direction XA and dF B  and dF C  are corresponding components due to the component velocities v B  and v C  in the directions XB and XC. The locus of the tips of all the velocity vectors, e.g. AC1, AC2, which would produce a predetermined beat frequency between the Doppler frequency components of the received A and C signals is a straight line 10AC parallel to the bisector AXC of the angle subtended at X by the transmitters A and C. A corresponding locus 17BC is defined by the beat frequency between the Doppler components of the received B and C signals and another corresponding locus (not shown) is defined by the received A and B signals, the tip of the actual velocity vector V being defined by the intersection of these three loci. The components of the actual velocity vector may then be determined by graphical construction or by a computer responsive to the Doppler beat frequencies. For aircraft speeds up to 1000 m.p.h. suitable values for F A , F B  and F C  are F, F + 1.008 mc/s. and F - 1.016 mc/s. where F is 1000 mc/s. At the receiver, Fig. 2, the received A, B and C signals are selected by filters 2, 3 and 1, the B and C signals are each heterodyned with a 1 mc/s. output from a local oscillator 4 giving signals (F + 8 kc./s. Œ dF B ) and (F - 16 kc./s. Œ dF C ) which are heterodyned with each other and with the A signal F Œ dF A  from the filter 2 in mixers 7, 8 and 9 giving signals 16 kc./s. + (dF A  - dF C ), 8 kc./s. Œ (dF A  - dF B ) and 24 kc./s. Œ (dF B  - dF C ) which are multiplied by nine in frequency multipliers 10-12 and applied through respective amplifiers 13, 14, 15 and pulse generators 16, 17, 18 to pulse counters 19, 20, 21. The frequencies represented by the outputs from the pulse generators 16-18 contain components due to the differences in frequencies of the transmitters and these components may be subtracted to known manner. Possible errors in the system are discussed with reference to Fig. 4 (not shown).

Abstract: 1481145 Electronic accounting machines ING C OLIVETTI & C SpA 16 July 1975 [2 Sept 1974] 29883/75 Heading G4A In a biprogrammable electronic accounting system which can execute alternately two programmes held with their data in respective zones of a memory, a manual change-over switch allocates a keyboard, visual display and abnormality-signalling-means selectively to one programme or the other. In the desk-top system disclosed, the abnormality-signalling-means are three lamps for indicating respectively: I/O channel error, operator intervention required by programme, and service message for operator present on the display, respectively. Further lamps are provided for indicating respectively: keyboard entry error, abnormality in the working out of the programme, keyboard buffer almost full. Another lamp and an acoustic signalling device are used to indicate that the programme not selected by the change-over switch has a message for the operator. This lamp is flashed, as distinct from lit, if the change-over switch is altered during keyboard entry. The programmes-and-data memory above is a RAM, a microprogramme ROM being provided also. A "biprogramming handler" microprogramme allots equal periods of time to the two programmes if they are both of internal type, whereas if at least one is of external type (i.e. involving a peripheral unit) the microprogramme optimises waiting times. The first programme may relate to invoicing or accounting work, and the second to file or record updating work (involving reading from an external support) or on-line data transmission work, in which case the operator may typically be using the keyboard &c. in connection with the first programme and switch over to the other when the latter signals that his intervention is required (e.g. for data error, reading error or programme end).
