Title: Improvements relating to the folding of lengths of flexible materials
Inventor: WILSON ROBERT
IPC: B65H45/101
Filed: 1962-08-02
Abstract: 976,545. Folding flexible material. D.& .J. TULLIS Ltd. Nov. 4, 1963 [Aug. 2, 1962], No. 29644/62. Heading D1S. A machine for cross folding lengths of flexible material e.g. for use in laundering comprises a conveyer 1 preferably formed by a number of adjacent ribbons 2 running about end rollers 3, 4, a folding blade 16 lying parallel to the direction of motion of the conveyer and a support table preferably made up of slats 23 which on actuation of the folding blade rise between the ribbons 2 to lift the material out of contact therewith, the blade 16 also moving the material to means, e.g. a roller pair 28, 30 and associated conveyer 26 to carry the material away. As shown the blade 16 is carried by a bar 13 and may be actuated by a pneumatic piston-cylinder arrangement 19. The table slats 23 are mounted on beams 8 carried by brackets 9 which slide on vertical rods 11 and are upwardly urged by springs 12. When the fold blade is inoperative the bar 13 engages brackets 14 on beams 8 and the table slats 23 are held below the conveyer as shown in Fig. 2. When the leading end of a length of material delivered to conveyer 1 by a conveyer 44, operates the feeler 24 of a switch 25, the pneumatic piston-cylinder 19 is operated to actuate the blade 16 and simultaneously the bar 13 rises to allow the table slats to rise and lift the material from the conveyer. The blade 16 pushes the cross fold between the roller pair 28, 30 and the material passes to a further conveyer 26. When the material on conveyer 26 simultaneously engages feelers 43, 41 of a pair of switches 42, 40 an arm 34, 35 is raised by a pneumatic, device 37 to grasp the leading edge of the material against a bar 38. The material continues to pass beneath its gripped leading edge until its trailing edge releases feeler 43 whereupon the gripped edge is released; the material is thus folded parallel to the first fold. A discharge tray 45 is provided at the end of conveyer 26.

Title: Controlling the deposition of salts in the tube systems of steam generators
IPC: B01J39/00
Filed: 1955-10-18
Abstract: The deposition of salts in the tube system of a forced flow steam generator which normally operates at or above the critical point of the working medium is avoided or is caused to occur at predetermined places by subjecting the feedwater to a so-called total salts elimination treatment such that its residual salts content after the treatment consists predominantly of one or more compounds of ammonium.  The treatment may comprise conventional cation exchange followed by anion exchange but in which the anion exchanger (or at least the last anion exchanger) is regenerated with ammonium hydroxide.  The anion exchange mass of a mixed bed ion exchanger (preceded by separate cation and anion exchangers) may be regenerated with ammonium hydroxide.  A base exchanger followed by a vaporiser may be regenerated with an ammonium compound.  In a complete steam power plant steam passes from a forced flow generator to a turbine and thence to a condenser.  The condensate passes through a mixed-bed ion-exchange plant to a feed water tank whence it is pumped back to the generator.  The ion-exchange bed is regenerated with ammonium hydroxide.  In a precipitation softening plant followed by a vaporizer the raw water may be softened by precipitation of hardness-forming salts by ammonium carbonate or hydroxide.

Title: Improvements in or relating to electromechanical transducers
IPC: H04R23/00
Filed: 1964-08-04
Abstract: 1,067,467. Semi-conductor transducers. SIEMENS A.G. Aug. 4, 1964 [July 23, 1963], No. 30699/64. Heading H1K. [Also in Divisions G1 and H4] A semi-conductor electromechanical transducer consists of a junction transistor having a pressure-transmitting needle bearing on its base electrode or base zone. The collector current of the transistor decreases as the pressure applied to the needle increases. (The Specification refers to a known transducer in which pressure applied to the emitter of a junction transistor causes an increase of the collector current). Silicon and germanium are suitable semi-conductors. In the embodiment of Fig. 1 (not shown) an oxide-protected planar NPN silicon transistor has a U-shaped aluminium base electrode 5 surrounding the strip-shaped aluminium emitter electrode 4. The pressure-transmitting needle bears on the base zone 2 through a hole in one side limb of the base electrode. To obtain maximum sensitivity the thickness of the base zone in the vicinity of the needle is decreased by local etching. The needle (consisting of ruby, boron carbide, or molybdenum) may be subjected to a mechanical bias so that the transistor is operated in a region of high pressuresensitivity. In operation, the standing collector current is set as low as possible consistent with reasonable current gain. The transducer just described may be used alone, or may be incorporated in a circuit with the known transducer mentioned above when the needles of the two transistors are arranged to move together and the circuitry is so chosen that the changes in collector currents are added in the output circuit. The same effect may be achieved in the transducer described with reference to Fig. 4 (not shown), in which a single planar transistor has pressure-transmitting needles bearing on both its base and emitter electrodes. The mechanical arrangements are such that the two needles move in opposite directions so that their effects on the collector current are additive. In all the pressure sensitive transistors mentioned above, it is not only the collector current which is varied by the applied pressure; the current gain is also affected and one may therefore take from the collector of such a transistor a modulated form of an alternating carrier fed to the emitter. The transducers may be used in microphones, vibrometers, accelerometers, listening apparatus, barometers and other pressure-measuring devices.
