Abstract: 1,121,384. Endless conveyers. ANS Inc. 7 April, 1966 [12 April, 1965], No. 15514/66. Heading B8A. A conveying system for sample holders 136 comprises a plurality of parallel adjacent guideways 15-22 in a horizontal plane, and each guideway having a movable floor formed by an endless belt 43-50, the belts of adjacent guideways moving in opposite directions, and the downstream end of one guideway being coupled to the upstream end of the adjacent guideway. The last guideway 22 of the system is coupled to the first guideway 15 by a guideway 35 formed with an endless belt floor 51. The guideway 15 is divided into two sections, each having an endless belt floor moving in the same direction as the other. An elevator 40 provided between these two sections lowers holders carrying samples into a treatment compartment and raises them thereafter. Three switches 150, 151, 152 positioned on the approach to the elevator and at varying heights up from the guideway floor cause the sample holders to be counted, energize the lowering mechanisms for the elevator 40, and reset the counter to zero, respectively. The drive motor for the belts is de-energized during movement of elevator 40. All the holders operate the switch included in the circuit of an electromechanical counter 150, only holders carrying samples actuate the switch 151 and a dummy sample in the last holder of a batch operates the switch 152 also in said counter circuit. The elevator raising mechanism is energized by means in the treatment compartment when the treatment is completed. The belts 43-50 are driven via pulleys mounted in shafts 75, 80 driven in opposite directions of rotation, from a common motor 70 through a chain 77. Idler pulleys are arranged alternatively with drive pulleys on the shafts 75, 80 such that adjacent belts are driven from opposite ends. The belt 51 is driven from the shaft 75 through bevel gearing 95. The lowering and raising mechanism of the elevator 40 is of the rack and motor-driven pinion type.

Filed: 1924-06-30
Abstract: 218,329. Telefunken Ges. f³r Drahtlose Telegraphie. June 30, 1923, [Convention date]. Atmospherics, eliminat - ing; coupling aerial and detector circuits.- In order to eliminate atmospherics, received energy is fed to the receiving circuit III through two opposed circuits I, II which are substantially aperiodic and of equal damping. The circuits I, II may be frame aerials or may be a coupling means with an ordinary antenna. One of them is of an inductive and the other of a capacitative character so that signal oscillations may have a phase difference on them as near as possible to 180‹ and will therefore have a cumulative effect on the circuit III. The non-periodic atmospheric disturbances are substantially balanced out. The theory of the system depends on the assumption that an atmospheric should be considered as the combination of a forced and a natural oscillation.
