Abstract: 850,268. Coin-freed vending machines. LUCKENWALDER METALLWARENFABRIK VEB. June 9, 1959, No. 19777/59. Class 27 A vending machine, having several compartments which are loaded from the rear and from each of which a commodity can be removed on lifting a coin-freed flap 7, has an indicator lamp 6 for each compartment to indicate to an attendant that a particular compartment is empty. A projection 8 on the flap contacts a switch segment 4 pivoted on. a lever 3 and rotates it so that a contact spring 5 moves into a deep notch 12 and closes the circuit to the lamp 6, the circuit being maintained when the flap swings closed. After the compartment has been refilled, the lamp, which is constructed as a pushbutton fitted on the lever 3, is depressed and the lever swings about its pivot 13 so that the segment 4 engages an abutment 10 and is rotated back to its initial position in which the contact spring engages in a shallow notch 14. The lever then falls under gravity to its normal position and the flap is locked in the closed position.

Inside the flanges 2, 3 are heating coils 4, 5 in the form of steam pipes interconnected by a pipe 6. A steam inlet pipe 7 projects from flange 2 and a steam outlet pipe 8 from. flange 3. Attached to the larger flange 2 is a recessed metal ring 10 having formed in the recess a ring 11 and a similar ring 12 is mounted on the outer face of flange 3 and has threaded apertures 13 and an aperture 14 for access to steam pipe 8. The cylindrical casing is in two parts 15, 16 interconnected by a flexible U-shaped ring 17 and heating coils 18, 19 interconnected by a pipe are attached to the parts 16, 16. Pipes 23, 25 pass through the casing which has U-shaped clamps 31 pivoted near the upper edge of the part 15 and on the undersurface of flange 26 are secured apertured blocks 32, threaded studs 34 passing through the apertures 13 and blocks 32 to draw the flanges together with the aid of nuts 35. Three steam heaters each in the form of upper and lower header pipes 36, 37 interconnected by vertical pipes 38 are arranged inside the casing and are connected to a common steam chamber 42 supplied with steam through a pipe 43. The pipe 23 is permanently attached to a manifold 46 which can be connected to a vacuum pump or a source of supply of impregnating compound for the cable. Pipes 22, 43 can be permanently connected to a steam supply but pipes 7, 8 are connected after the drum has been lowered into the casing.

Abstract: 238,882. Dayton Fan & Motor Co., (Assignees of Marvel, O. E.). Aug. 23, 1924, [Convention date]. Thermionic amplifiers and detectors; coupling aerial and detector circttits.-In a wireless receiving circuit of the inverse dual type a transformer 34 is adapted for working on aerials with various constants by providing a condenser 101 between the primary and secondary windings which is stated to cause a variation in capacity between the windings when one is moved relatively to the other and enables the aerial circuit to be tuned indepndently of adjustment of condenser 36 so that for a given wavelength the settings of condensers 36, 45. 54 may be identical and independent of the aerial constants. Fig. 1 shows amplifying valves 20, 21 having the high and low frequency inputs connected in series and the outputs in parallel. The aerial 35 is coupled to the valve 20 by means of the transformer 34 and the valves 20. 21 by a transformer 39 tuned by condenser 45. An auto-transformer 48 tuned by condenser 54 serves to impress the output of the valve 21 on the detecting valve 22. Fig. 5 shows the construction of the transformer, the secondary 103 being mounted on a bracket 105 and the primary 102 rotatable. In a modification the low frequency output of the valve 21, instead of being applied to the valve 20, is applied to an additional amplifying valve and a radio frequency choke replaces the telephone in the plate circuit of valve 20.
