[Classes 36 and 37.] A heavy alternating-current feeder, particularly for use in connection with valve transmitters, comprises a pair of insulated conductors, one of which is formed with a movable section so arranged as to permit variation of the feeder inductance. As shown in Fig. 1, a feeder comprises adjacent metal strips a, c separated by insulation b, the strip a being formed with a rectangular step and the strip c lying only along the parallel portions of the strip a. The continuity of the strip c is completed by a movable step-shaped metal strip d which in conjunction with the step in the strip a encloses a rectangular loop, as shown. Movement of the strip d along strip c causes an increase or decrease in the area of the loop and corresponding changes in the inductance of the feeder. In a modified construction the loop takes the form of a parallelogram. The conductive strips a, c, d may be provided with a series of corresponding holes through any of which insulated clamping bolts may be passed, or the strip d may be held in contact at each end with the strip c by bolts passed through holes f formed in insulating clamping plates e, as shown in Fig. 3. The ends of the strip d may be finally soldered to the strip c. In a construction applicable to a concentric tubular cable, shown in Figs. 4 and 5, a semicircular bend is formed in the cable and half of the outer conductor a is cut away at the bend so that it may be rotated relatively to the inner conductor c.

Filed: 1930-05-30
Abstract: 360,407. Metallic-vapour apparatus. LUTZ, F., 32, Sulgenauweg, Berne, Switzerland. May 30, 1930, No. 16733. Convention date, June 29, 1929. [Class 39 (i).] A mercury - vapour rectifier has an upper cooler 0 for the anodes A, the cathode K, and the condensation chamber D, and a lower cooler U which determines the vapour pressure in the anode chambers. The coolers may be in series, the cooling medium being passed first through the lower cooler to keep it at a temperature lower than that of the cooler O. Cooling may be effected by forced or natural air draughts. Alternatively, evaporative coolers may be used, the vapour from the cooler O being used, e.g. by means of a jet pump, to reduce the boiling-point and consequently the temperature of the liquid within the cooler U. Members F guide the vapour to the cooled surface B and the condensate may be returned to the cathode by an auxiliary vaporizer. The Specification as open to inspection under Sect. 91 (3) (a) states also that each cooler may consist of a number of separate coolers e.g. the cooler 0 may consist of a liquid cooler for the condensation chamber and air coolers for the anode chambers. Ribs may be provided on the chambers to facilitate cooling by air. This subject-matter does not appear in the Specification as accepted.

Title: Control means for screw-operated dispensing machines
IPC: B65B1/40
Filed: 1952-07-04
Abstract: 698,657. Screw conveyers. HESSER MASCHINENFABRIK-AKT.-GES., F. July 4, 1952. [July 14, 1951] No. 16871/52. Class 78 (i). In dispensing machines for powdered material of the kind in which the drive of the delivery screw is cut off automatically after a number of revolutions corresponding to the quantity of material to be delivered, the control means are arranged to be operated directly by the screw and to be returned positively to the same starting position after each dispensing operation. The screw 2 is disposed within the mouth of the hopper 3 and its shaft 1 is driven by a motcr M through means including an electric coupling 4 which is switched in by means of gear controlled by the cam shaft 17. A worm 5 on the shaft 1 drives a worm wheel 6 which surrounds a disc 7 and is connected thereto by a freewheel device 8. A tension spring 9 anchored at 10 is connected to the disc and tends to turn it in the direction of the arrow. A roller 11 on the disc engages slot 11a in an arm 12 projecting from a rod 13 which can move vertically in a guide 14 and rests on a rotary cam 16. A switch contact 18 is mounted on a finger 18a carried by the bar and a corresponding contact 19 is mounted on a slide 22 which can be secured in any desired position on a graduated bar 21. The quantity of material fed is varied by adjusting the initial distance between the contacts. When the machine is started, the cam 16 turns anticlockwise to release the rod 13 and the worm drives the wheel 6 in the direction of the arrow. The disc 7 is turned in the same direction by the spring 9 and moves the rod 13 downwards until the contacts 18, 19 engage. When this occurs, the coupling 4 is interrupted and the screw 2 stopped. The cam 16, however, continues to rotate and eventually restores the rod 13 to its initial position. As the rod rises, the arm 12 turns the disc 7 against the action of the spring 9. During this movement the wheel 6 is not coupled to the disc ; but, when the cam releases the rod, the spring tends to rotate the disc clockwise and the connection is restored. In a modification (not shown) the cam 16 is dispensed with and the rod 13 forms the core of a solenoid.
