Abstract: An apparatus for testing for leaks in individual cavities, such as pin sockets, in a component, such as an electrical connector, in which the pin sockets or other cavities to be tested for leaks extend into said component from a surface of the component is provided. The apparatus of this invention includes resilient means for sealingly engaging said surface of the component which surrounds the socket or other cavities. There is provided through the resilient means a plurality of deformation resistant apertures, which may be, for example, hollow metal tubes, such as hypodermic needles protruding through said resilient means. Said apertures are geometrically arranged to correspond to the arrangement of said cavities so that one aperture is in alignment with the opening of each cavity. Each of said apertures is connected by a conduit to a pressure sensing means, which is capable of measuring the rate of pressure decay or leakage out of the test section or cavity. Means is also provided for simultaneously introducing a gas under pressure to each of the apertures. A suitable valve mechanism is provided for turning off the gas supply so that the rate of leakage, after such pressurization of the cavities, can be measured.

Abstract: Methanosarcina alcaliphilum  bacteria are described which are alkalophilic, methanogenic and have an optimum growth pH range of from about 8.1 to about 8.7. A preferred bacterium is  Methano­sarcina alcaliphilum  (NY-728) FERM BP-2309. These bacteria exhibit excellent properties such as alkalophilicity and resis­tance to low temperature. They make it possible to carry out methane fermentation methods at an alkaline pH and at low temperature conditions. The bacteria are applied in methane fermentation in treating solid waste and waste water. Moreover, the concentration of the bacteria in a reactor can be increased within a very short time and, therefore, the size of such a reactor can be made compact.

Abstract: For taking liquids from deep voluminous vessels by aspiration containers with short suction pieces, a metered intermediate volume of liquid, accessible from above, is aspirated from a liquid volume of changing depth in the vessel. Simultaneously with this aspiration, a defined sample of liquid is sucked off. This suction aid possesses a tube which can be introduced into the vessel and a non-return valve closing towards the lower tube end. This tube (5) is arranged on a dish (2) which can be placed upon the mouth (6) of the vessel. Preferably, the dish (2) is part of a housing (1) in which the upper opening (16) of the tube (5) is arranged close to the cover wall (12) and, in the upper part of the dish (2), above the intermediate volume of the liquid held at least in the dish (2), there is an inlet opening (13) for the tip (14) of a working vessel (15) provided with a piston. With each sampling, an intermediate volume of defined depth is always produced in the housing.

Abstract: The control circuit stabilises the output voltage (UA) of a power supply, the input voltage (UE) of which is chopped into an alternating voltage, before transmission to the output electrically isolated from the input, by means of a switching transistor (1), in that a voltage signal dependent on the output voltage (UA) alters the switch-on duration of the switching transistor (1). In this arrangement, this voltage signal is conducted on a transmission path having an electrical isolation point. This control circuit is to be of simple construction and be characterised by a high degree of control precision even after many years of operation. This is achieved in that the transmission path (5) has the following elements: an oscillator (6) for forming output-voltage- dependent frequency signals which is controlled by output-voltage- proportional voltage signals, a pulse transformer (8) for transmission of the frequency signals acting on its input, and a frequency control circuit (16) electrically isolated from the oscillator (6) for converting the transmitted frequency signals into signals corresponding to a mapping of the output voltage (UA). <IMAGE>

Abstract: An elastomeric sleeve (C) is placed under axial compression in a pinch valve assembly. The axial compression of the sleeve eliminates any crevices with end members (E) which engage opposed end walls of the valve body (B). Mechanical gripping of enlarged flanges (24, 26) defined at opposed ends of the sleeve (C) is also enhanced through axial compression of the sleeve. A positive, visual indication of valve-open and valve-closed positions is provided by an indicator stem (142) extending outwardly from an actuator body. The flanges may be reinforced. Additionally, a casing member (170) may be interposed between the valve body (B) and the sleeve (C) for ease of replacement and maintenance. A vent opening (212) in the valve body (B) eliminates pneumatic closure forces on the elastomeric sleeve (C) that can arise when the pinch valve is heated. The vent opening can also be connected to a valve (216) to provide venting of the valve body.

Abstract: During the processing of video signals, a signal flow fluctuating with time must be expected from certain signal sources such as, for example, in the case of a video recorder. However, the process of writing into a frame buffer is carried out with a crystal-controlled clock. For this reason, the incoming video signal which has signal flow fluctuations, must be conditioned in an interface to the frame buffer in such a manner that during the process of writing-in with a stable clock, an error-free storage of the video signal in the frame buffer is ensured. The interface according to the invention enables the video signal to be stored without errors. It consists of a buffer store which is arranged between the analog/digital converter of the processing unit and the frame buffer, this buffer store being driven by a control device which consists of an input controller, an output controller and an address comparator. The control circuit is designed in such a manner that data are temporarily stored when the data flow of the analog/digital converter is faster than the data flow into the frame buffer and that the output to the frame buffer is stopped when the data flow in the analog/digital converter is slower than the data flow into the frame buffer. <IMAGE>
