Title: Sound transmitting arrangement
IPC: G01S1/72
Filed: 1920-07-09
Abstract: 147,945. Signal Ges. Aug. 12, 1918, [Convention date]. Subaqueous audible signals. - The alternator supply circuit of an electro-magnetic sound-transmitter, especially for subaqueous signalling, is tuned to the working frequency, which is also the natural frequency of the transmitter, by a condenser 9. This enables a smaller machine to be used, and either broader resonance is obtained or else, by constructing the transmitter to have less than the normal mechanical damping, greater efficiency is obtained with the normal breadth of resonance. The power curve of the arrangement with relation to frequency is of the form shown in Fig. 2, with a depression at the tuned frequency, and by working on an ascending portion of this depression the alternator runs with good speedstability. The transmitter is polarized by a direct-current winding in a circuit 6, 7.

Title: Improvements in or relating to the operation of multi-stage ion-exchange water treatment systems
IPC: B01J39/00
Filed: 1956-06-29
Abstract: In a process for the treatment of water by a multi-stage ion-exchange process, wherein the water is such that finely divided solid particles are precipitated therein by its passage through a cation-exchange material, the effluent from the cation-exchange stage is passed through a filtration unit to remove the precipitated particles before entering at least one anion-exchange material.  The process is particularly applicable to waters containing traces of silicates and/or basic acid.  The filtration unit should be capable of retaining particles of submicron size and may comprise a bed of porous carbon granules e.g. anthracite or activated carbon.  Suitable ion exchange resins may be prepared from styrene/divinyl benzol.  The process extends the life of the anion-exchange material.

Title: Improvements in centrifugal servo-motors
IPC: B60T13/06
Filed: 1947-07-28
Abstract: 627,180. Centrifugally-operated brake servomotors. PIGANEAU, P. G. July 28, 1947, No. 20335. Convention date, Sept. 17, 1941. [Class 103 (i)] A centrifugally-operated servomotor, particularly for actuating vehicle brakes, is characterized in that at low speeds of the vehicle power unit or main driving unit, the centrifugal masses of the servomotor are driven by an auxiliary power unit, the speed of which is independent of the main unit. In Fig. 1, the servomotor is shown in the stationary condition. Rotation of the control shaft 23 makes the centrifugal masses 24 move outwardly against the inclined ramps 25 and thus moves the plate 22 against the spring 27 so as to operate the brake or other output member 31 through the rods 29. The entire servomotor 1 is mounted on a longitudinal pivot 62, as in Fig. 4, and on the first movement of the control lever 58 is moved on this pivot by means of a mechanical linkage (not shown) so that a member 63 rotating with the main power unit is engaged with a pulley 48 freely mounted on the shaft 23. Due to the inertia of the masses 24 and plates 21, 22, the pulley 48 drives the shaft 23 through a free-wheel device comprising the screw 51, threaded nut 50, spring 52 and friction disc 49. A further movement of the control lever 58 closes a contact 66 to energize an electric motor 53 driven at a steady speed by a battery 69, this motor being coupled directly to the shaft 23 by chain and sprocket drive 54, 55, 56. If the speed of the main power unit falls below a certain value, the servomotor is then driven only by the motor 53, the pulley 48 rotating idly at a lower speed due to the free-wheel device 49, 50, 51, 52.
