Abstract: 1512171 Substation arrangements INTERNATIONAL MOBILE MACHINES CORP 23 Jan 1976 2668/76 Heading H4K A substation arrangement for allowing ringing signals from an exchange to reach the bell of a telephone only if the caller sends an extra predetermined signal comprises a relay which when energized opens a contact in the ringing path, actuating means coupled to the exchange and arranged to energize the relay during detection of a ringing signal, a switch means arranged to deenergize the actuating means upon detection of the predetermined signal and power supply means arranged to store energy from the ringing signal and to supply power to the substation equipment. In one form ringing signals on a line 12, 14 rectified in a bridge 16, 18, 20, 22 enable a relay 44 the normally closed contacts 70 of which open to prevent the ringing signals reaching the telephone bell. A multi-frequency code transmitted by the caller is filtered at 64 and converted in a compression amplifier to a constant level signal which is mixed with each of the two frequencies of a first multi-frequency digit such that a correct first digit will produce a beat frequency capable of passing through a low pass filter. The output steps a flipflop chain to cause a matrix to select two further frequencies for the second digit and if this is correct to disable via a transistor 42 the relay 44 allowing the ringing signal to reach the substation bell. The power for the equipment is stored on a capacitor 50 charged by the ringing signals. The flip-flop chain is reset by a slowly charging capacitor 54.

Title: Process for producing boiler feed water
IPC: B01J39/05
Filed: 1958-01-28
Abstract: To reduce siliceous deposition in boilers, crude water, e.g well or river water, is softened by sodium base exchange and treated with one or more base exchangers charged with potassium ions or with sodium ions and potassium ions, before being used as boiler feed water.  The presence of potassium salts in the boiler water is stated to reduce the volatility of silicic acid and to reduce the tendency of alkaline boiler water to foam.  The boiler feed water may be filtered, after being softened by one or more sodium base exchangers, through a base exchanger charged with sodium ions and potassium ions, or the crude water may be divided into streams, at least one of which is filtered through at least one sodium base exchanger and at least one of which is filtered through at least one base exchanger charged with potassium ions or with potassium and sodium ions, the streams being subsequently reunited.  Examples are given.

Abstract: 556,552. Aircraft controls. GENERAL AIRCRAFT, Ltd., WELS, O., and MARCZEWSKI, Z. March 5, 1942, No. 2919. [Class 4] Bracket means attached to a strong point on the aircraft carries the elevator rudder and aileron controls which act through levers rotating with or on a common transverse shaft carried by the bracket means. In one form, two brackets 5, 6, connected by a fitting 7 to a cabin bulkhead, support two shafts 8, 23 carrying pillars 20, 22 on which a control member 21, 26, similar to that described in Specification 546,210, is mounted. An arm 10, Fig. 2, is fixed to the pillar 20 and is connected through a rod 12 and bell crank lever 29 to the elevator. An arm 27, fixed to the part 26 of the control member, is connected by a link 28 to a bell crank lever 11 pivoted on the shaft 8 and actuates the ailerons through a second rod 12 and bell crank lever 29. Two pedal levers 15, 16 are mounted on the shaft 8, the lever 16 being pinned thereto while the lever 51 is keyed to an arm 9 for actuating the rudder through a third rod 12 and bell crank lever 29. The two arms 15, 16 are constrained to move in opposite directions by links 19 and rocking lever 18. The setting of the control rods close together enables them to be grouped in a floor duct. The lower parts of the pedal levers are hinged to enable them to be adjusted to suit pilots of different leg lengths, a spigot 34, Fig. 4, movable by a treadle 38 engaging any of the three sockets shown. Fig. 5 shows another form in which all the controls are mounted on a tube 1 adapted to be secured to the airframe. In this case a control lever is mounted on a shaft 21 journalled in bearings suspended by links 20, 22 pivoted on transverse shafts 2, 3 extending from the tube 1. An arm 27 on the shaft 21 actuates the ailerons through a link 28 and lever 43, and an arm 44, keyed to the shaft 3 to which the link 22 also is keyed, actuates the elevator.' Two pedal levers 15, 16 respectively loose on and fixed to the shaft 2 are interconnected by a rocking-lever, not shown, and the lever 15 actuates the rudder through a link 4 and lever 42 pivoted on the shaft 3. In both forms dual controls may be coupled abreast by extending the shafts 8, 23 or 2, 3, the aileron controls being coupled by transverse rods extending from arms 27 on the rotating part of the column to the end of a lever mounted on a universal joint through which motion is transmitted to the aileron control. Alternatively two sets of controls may be mounted in tandem, the second set being connected to a second set of levers 29 in the transmission to the control surfaces. Specification 546,210 is referred to.

The feeder 7 is normally held in inoperative position by a projection 22 on a shuttle feeder 6 that is held in full line position by a lever 2c controlled from the weft feeler mechanism through a shaft 1 and members 2a, 2b. When the shaft 1 is rotated the members 6, 7 fall into dotted line position and a locking lever 9, controlled by the shuttle feeler 6; moves an angle piece 12 into locking engagement with a notch 13 in the feeder 7. On the next advance of the lay, the stationary shuttle raises the front wall 20 and passes into the box to be imprisoned by the lowered front wall and withdrawn from the spring-controlled grippers 19 of the feeder 7 on the next backward stroke. The feeder 7 is unlocked only on completion of the transfer or when an improperly positioned shuttle leaves a stop in the path of the shuttle feeler.
