Title: Improvements in electric supervisory arrangements for remote control systems
IPC: H04Q9/04
Filed: 1929-03-09
Abstract: 307,515. Siemens & Halske Akt.- Ges. March 10, 1928, [Convention date]. Selective distant control systems. - Supervisory arrangements for remote control systems are so arranged that the controlling operator can distinguish between failure of the selective control apparatus and the non-operation of a faulty switch or the operation of a switch followed by its immediate release due to a short circuit. For this purpose, the receipt at the substation of the controlling impulse causes the same signal to be transmitted to the main station as the successful operation of the selected switch, this signal being followed after a determined period by a signal indicative of the actual position of the selected switch. To close the switch 1, the operator at the central station H moves the corresponding switch 19 to close contact 20, a circuit being closed from positive of battery 25, through the distributer arms 15, 16, for the polarized relay 29, which closes a local circuit through the switch-operating magnet 3, normal contact 50, and hold-on winding 46, this circuit being opened at contact 50 when the switch is fully operated. Relay 29 also closes at contact 70 a circuit for a relay 55, which locks up over winding 71 for a period determined by a thermal interrupter 61, and connects positive potential over contact 57 to the contact 41 of the distributer 16 so that an indicator 42 at the central station shows that the selective control apparatus has operated, whether the switch 1 has been successfully operated or not. After the relay 55 has released, the contact 41 is connected over contacts 45, 35 to positive or negative according to the position of the switch 1. To open the switch, the operator closes contact 21 causing the polarized relay 29 to close a circuit through the off-normal contact 51 and magnet 7, which allows the spring 4 to open the switch. Specification 287,498 is referred to.

Title: Method and apparatus for producing filled tetrahedron-shaped packages
Inventor: MOBLEY GEORGE A
IPC: B65B9/22
Filed: 1970-02-19
Abstract: 1302766 Packaging DEERING MILLIKEN RESEARCH CORP 19 Feb 1970 [20 Feb 1969] 8084/70 Heading B8C  In a machine for making tetrahedral packages by the action of heat sealing jaws 40 on a continuously advancing tube, means are provided for maintaining the registration of print on the packages. The tube is formed by a ring 22 from paper stock bearing indicia 76 whose position, as sensed by a photo-cell 74, controls the diameter of the ring 22, and therefore the length of paper used for each package, to correct the position of the print. The tube is advanced by the jaws 40, which are mounted on continuously driven chains 36 and 38. The ring 22 comprises a fixed member having a forming aperture whose size is varied by an overlying sliding member which is moved by a piston 90 (Fig. 4). The tube diameter is controlled by an arrangement including two cams 94 and 96 which are rotated in synchronization with the movement of the heat sealing jaws 40. During part of its rotation, the cam 94 closes a switch 98 to energize an amplifier 100. If, while the amplifier is energized, the photo-cell 74 senses an index 76, a valve 78 is moved to its dotted line position by means of a relay 120 and switch 122 so that compressed air from a line 80 is supplied to the right-hand side of the piston 90 to reduce the diameter of the tube. The valve 78 is locked in this position by a switch 102 until the cam 96 opens the switch 102 to reset the control circuit and to return the valve 78 to its full line position so that the piston 90 is moved to the right. If an index is not sensed while the amplifier is energized, the relay 120 is not operated and the piston remains in its right-hand position. In a modification, the forming ring 22 comprises two rings, one arranged within or above the other, and the rings are relatively tilted to vary the tube diameter.

Title: Improvements in or relating to circuit-arrangements for indicating the frequency of electrical oscillations
IPC: H03J3/12
Filed: 1947-03-25
Abstract: 629,322. Electric tests. PHILIPS LAMPS, Ltd. March 25, 1947, No. 8097. Convention date, July 15, 1944. [Class 37] [Also in Group XL (c)] In a circuit for indicating the correct tuning of an electrical device, a voltage depending in magnitude and sense on deviation from correct tuning is fed from a frequency-detector to at least two electrodes of a valve having a cathode and two or more other electrodes, so adjusted that an indicating voltage having an extreme value for correct tuning is obtained from one of the other electrodes. As shown, Fig. 1, the output of a frequency detector is applied to the control grid of a pentode 2, and indirectly over a cathode resistor 5 to the suppressor grid. The output is taken from the anode via a potentiometer 6 to the grids of the triode sections of a cathode-ray tuning indicator 8. The pentode 2 is adjusted so that the output is a minimum for correct tuning, and the bias supply 7 for the triode sections is chosen so that the width of the light spot is then a maximum. The output of the pentode 2 may be applied directly to the deflection plate of a cathode-ray tuning indicator, which gives a light spot of minimum width for correct tuning, Fig. 2 (not shown). In another embodiment, Fig. 3, the frequency detector output is applied to the suppressor and control grid of a pentode 2 through oppositely-connected diodes 11. The output is taken from the screen grid, and a cathode resistor 5 provides negative feedback. In a modification, Fig. 4 (not shown), the input voltage is applied through high resistances to the suppressor and control grids of a pentode valve such that, for positive inputs, the control grid and cathode of the valve act as a diode, the cathode resistor being omitted. A diode may be connected between the control grid and earth, Fig. 5 (not shown). In order to avoid the indication of correct tuning in the absence of a signal, the grids of the triode sections of the cathode-ray tuning indicator may be connected to discharge tubes controlled by the A.G.C. voltage of a receiver, or the bias for these grids may be provided by the A.G.C. voltage. The circuit may be used as a null-voltage indicator.
