Title: Improvements in or relating to multiplying devices
IPC: G06G7/162
Filed: 1960-04-22
Abstract: 871,711. Electric analogue calculating systems; power measurements; measuring-bridges. LANDIS & GYR A.G. April 22, 1960 [April 25, 1959], No. 14236/60. Class 37. A multiplication device comprises a bridge circuit 5, Fig. 1, having arms comprising identical resistors 3, 4 and identical resistance members 1, 2 whose resistance is much less than that of resistors 3, 4 and varies with an applied magnetic field, and two series-connected energizing windings 14, 15, the signals U1, U2 representing the two multiplicands being applied at terminals 6, 7 and 16, 17 respectively. A constant magnetic field Bo is applied to each member 1, 2 so that their resistance is in quadratic relationship with the applied field, and windings 14, 15 are arranged to apply equal and opposite fields B1, B2 to members 1, 2 respectively, the unbalance voltage appearing across the output terminals 9, 10 of the bridge being proportional to the product U1, U2. A modification of the device, Fig. 3, may be used for measuring the active or wattless power in an A.C. main 21. To determine the active power, windings 14, 15 are energized by a current representative of the current flowing through load 23 and derived from transformer 22, and transformer 24 supplies the bridge with current representative of the mains voltage. The wattless power is measured by connecting terminals 16, 17 across the mains and supplying a current proportional to the load current to terminals 6, 7 through a transformer. Similar measurements may be made for polyphase mains supplies by employing a plurality of multiplication devices whose bridge outputs are connected in series with an instrument indicating the sum of the outputs. Initial inequalities in members 1, 2 may be compensated by replacing resistors 3, 4 with a potentiometer and including a further potentiometer between members 1, 2, terminals 6, 7 being connected to a tapping on the respective potentiometer. Similarly balancing inductances or a potentiometer may be included in the energizing circuit, windings 14, 15 being fed in parallel, to ensure that fields B1' B2 produced by the windings are equal.

Title: Method of producing acid-proof, adherent and repairable coatings from artificial resins
IPC: B05D7/26
Filed: 1926-06-08
Abstract: 253,531. Koolman, C. ten Doornkaat-. June 9, 1925, [Convention date]. Coating processes.-Acid-proof coatings of artificial resins, which can be easily repaired, are produced by applying one or more layers of artificial resin alternately with one or more porous layers of a mixture of artificial resin with acid resistant materials such as asbestos kieselguhr or graphite, and hardening the whole. The coating is adapted, by reason of the porous intermediate layers, to absorb fresh artificial resin when damage occurs and the edges of the damaged portion are exposed, whereby intimate connection between the new and old layers is effected. Cracks &c. may also be repaired by grinding them with emery or like abrasive so that the abrasive powder enters the crack and applying a thin solution of artificial resin which is absorbed both by the porous layers and the abrasive powder. Alternatively the crack may be filled with kielselgurhr &c. instead of utilizing the abrasive powder. The repair is varnished and finally herdened.

Title: Improvements in and relating to means for producing music electrically
IPC: G10H5/08
Filed: 1931-05-21
Abstract: 371,641. Electrical musical instruments. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. -(Assignees of Carlson, W. L. ; Kings Highway, Haddonfield, New Jersey, U.S.A.) May 21, 1931, No. 15051. Convention date, May 22, 1930. [Class 88 (ii).] Relates to the employment of two oscillators, each producing a fundamental and harmonics, of different frequencies so that a beat note is produced, with means for varying the pitch intensity and timbre of the beat note. Referring to the Figure, the two oscillators O, O<1> are tuned initially to the same radio frequency, and are connected through a potentiometer 18<1>, detector 19 and amplifiers 20, 21 to the loud-speaker 23. The oscillators have tuned circuits 4, 5 .. , 4<1>, 5<1> .. , respectively for their fundamentals and harmonics, coupled to them in parallel or series and connected to amplifiers A, A<1>. Short-circuits, comprising condensers 10, inductances 11 and variable resistances 12 under the control of spring- biased keys 24, and tuned to the fundamental and harmonics respectively of the oscillator O, control the amount of each component therefrom transmitted to the potentiometer 18<1>. A beat note of varying pitch is produced by varying the frequency of the oscillator O<1> by means of key-switches 17 in the circuits of condensers 14 of different capacity, the intensity of the fundamental and of each harmonic in the beat note being under the control of the keys 24. Oscillator frequencies sufficiently high are used to permit the required range of notes to be produced without overlapping of the components and without necessitating adjustment of the circuits 4<1> .., the action of the keys 24 thus being kept distinct. The leads 13 from oscillator O are connected across a portion only of the potentiometer 18<1> to prevent distortion ; or the generator O may be of smaller capacity than the generator O<1>. In Fig. 2 (not shown), the circuits of the fundamentals and of corresponding harmonics from the oscillators O, 01 are respectively connected together, under the control of keys 24, and are coupled to separate circuits each including an amplifier and detector, the output circuits of the detectors being connected to a single amplifier and loud-speaker. In Fig. 3 (not shown), the oscillators O, O<1> are each connected to an amplifying valve caused by negative grid-bias to operate on the curved part of its characteristic and thus to generate harmonics ; and the frequency of oscillator O<1> is varied by movement of the hand of the operator near a vertical electrode. Tuned circuits connected to suitable portions of the potentiometer carry the two fundamentals and the pairs of corresponding harmonics to separate circuits each including a radio-frequency amplifier with negative grid-bias, an audio amplifier, and a loud-speaker. The keys 24 are then arranged to control the grid-bias of the radio-frequency amplifiers.
