Filed: 1972-10-26
Abstract: 1400630 Automatic exchange systems SIEMENS AG 26 Oct 1972 [29 Oct 1971] 49355/72 Heading H4K In a telecommunication system in which an intermittent dialling tone is employed and subscribers transmit wanted subscriber numbers in frequency form, the exchange upon initial recognition of the first frequency or frequency code digit transmitted maintains the dialling tone in its current on or off state until that digit ceases to be detected. The object is to eliminate the possibility of a multiple signal arising if the signals require onward transmission. As shown a subset Tln is coupled to an exchange register REG and a multi-frequency receiver MFE. A control unit RSE upon offhook detection closes a contact d and periodically closes a contact S intermittently enabling a relay WZ, a contact WZ2 of which connects a tone generator WG intermittently to the line. When the first digit is recognized the receiver MFE enables a relay GK which via its contact gk holds or prevents further operation of relay WZ until the digit ceases to be received, the control operating a contact Ua to release relay GK at this time.

Transistor T 4  is normally conducting, the current through coil 11 maintaining the shutter open. T 4  is switched to the non-conducting state by transistor T 3  when the difference voltage has reached its predetermined value. Potentiometer 14 is adjusted to take account of exposure factors, e.g. film speed, diaphragm aperture. Resistor 13 is adjusted to take account of the γ of the photo-conductive element 1. A second embodiment is described, Fig. 2 (not shown) which uses three differential amplifiers and has an indicator (25) giving the controlled exposure time.

Abstract: 1435394 Sorting postal mail LICENTIA PATENT-VERWALTUNGS GmbH 30 Oct 1973 [31 Oct 1972] 50415/73 Heading B8A In a sorting installation for light mail, items of mail are selectively passed on to a plurality of sorting channels by a plurality of sorting stations spaced along the sorting channels and the number of items of mail simultaneously passing a predetermined point of each sorting channel is  determined, an output signal being produced if the number exceeds a predetermined value. The figure shows diagrammatically a sorting installation, sorting stations 11-17 feeding sorting channels 100-500 via switchpoints 111-517. Data processing device 60 receives address information from each sorting station, controls the operation of switchpoints 111-517 in dependence on this information, and by means of simulation determines the number of items of mail immediately before each switchpoint connected to each of the sorting stations 15-17 at any moment. By storing and adding this information, the number of items of mail passing along a section of the sorting channels between two these stations 15-17 may be determined. Alarm signals are produced if either the number of items passing any switchpoint or the number of items in a section of the sorting channels is likely to cause a blockage at processing devices 51 (in this case, continuous separators) which can only handle a limited density of items at a time.

Title: Arrangement for use in detecting an amount of a flowing medium exceeding a preset quantity
IPC: G01F15/075
Filed: 1977-12-07
Abstract: The pulses output by a pulse transmitter counter are supplied to a pulse counter which is presettable to the amount and which, when its preset number of pulses is reached, increments a transgression counting mechanism by one step by releasing a pulse and which is reset to its starting position with the aid of a time base counter after each measuring period has elapsed. If the preset number of pulses of the pulse counter is reached during a measuring period, the transgression counting mechanism is incremented by one step by the pulse occurring in this event, and both the time base counter and the pulse counter are reset to their starting positions. To achieve an appropriate adjusting comfort, it is required to be able to predetermine the mean power limit value, to be monitored for transgression within a measuring period, as an integral value. This is made possible by the fact that the duration of the measuring period and a mechanical step-down transmission (25 to 29) of the rotor (24) of the pulse transmitter counter, driving the pulse transmitter (33 to 35), are matched to one another. <IMAGE>
