Title: Process for the biological treatment of waste water using microorganisms
Inventor: STOG JOCHEN
IPC: C02F3/06
Filed: 1990-03-21
Abstract: Abstract The invention concerns a process for the biological treatment of waste water using microorganisms, in which the microor-ganisms breed and develop in a contact path (I) and in which optimum living conditions are maintained for the microorganisms by the addition Or waste water to be treated and appropriate quantities Or air (2). A portion Or the microorganisms leaving the contact path (I), which will have developed well in the soiled water, are fed back (6) into the contact path in order always to have exactly those microorganisms available that are particularly suitable for the waste water to be purified and at the same time suffi-cient quantities of these healthy microorganisms. In addition, a small sample of waste water is taken, well away from the contact path (1), as an indicator, and introduced (17) into the microorganism development area as a kind of early-warning enabling time-ly preparations to be made for the development of the microorganisms. This process, together with a device suitable for carrying it out, enables the degree of purification to be kept constant, the uniformity of the food supply and the wide and optimally bal-anced variety of microorganisms, as well as the balanced oxygen supply or efficiency of aeration, making it possible to adapt several variables, either individually or together, to changing conditions.

Abstract: A television system comprises a first input terminal (20) for providing a composite video (CSCC) signal or a separated luminance (SCC) signal, and a second input terminal (15) for providing a separated chrominance (C) signal. A change-over switch (11) has a first input (a) coupled to the first input terminal (20) through a path including a color subcarrier filter (9), a second input (b) coupled to the second input terminal (15) through a path not including the color subcarrier filter (9), and an output (c) coupled to the input (d) of a color decoder (8). The change-over switch couples the input (d) of the color decoder (8) to the first input terminal (20) in a first position (a), and couples the input (d) of the color decoder (8) to the second input terminal (15) in a second position (b). A subcarrier detector (CK) is coupled to the output (c) of the change-over switch (11) for detecting the presence of absence of a color subcarrier. A control unit initially causes the change-over switch (11) to be in the first position (a) and thereafter causes said change-over switch (11) to remain in the first position (a) if a color subcarrier is present at the output (c) of the change-over switch (11), but causes the change-over switch (11) to be in the second position (b) if a color subcarrier is not present. Once the change-over switch (11) is in the second position (b), the control unit (1) causes said change-over switch (11) to be switched back to said first position (a) from said second position (b) if a color subcarrier is still not present.

Title: Earphone-type speaker assembly
Inventor: GLUZ JACOB
IPC: H04R1/10
Filed: 1992-06-11
Abstract: ABSTRACT     A speaker assembly for securement to the temples of an eyeglass frame,such as sunglasses, is disclosed. In particular the assembly includes an adjustable support which is detachably secured to the temples or fixed permanently thereto. The speaker is supported spaced from the frame and the particularity of its mounting is that it can be pivoted to emitt sound towards the ear of a wearer or fully away from the ear or any intermediate position. This permits the wearer to adjust the direction of the speakers to hear other important sounds that may be directed at him from his back or sideways. Accordingly, if the wearer is listening to the radio in an area where important sounds need to be heard, such as in vehicle traffic, the traffic sound will overpower the earphone speaker sound.
