Filed: 1980-06-19
Abstract: The invention concerns a method and an arrangement for controlling, regulating and indicating the flow of ventilation air in ventilated rooms, such as an exhaust hood 2 at laboratory work stations and the like. At each exhaust hood 2, a first position pickup 15 is arranged to put out information as to how open or closed the shutters 3 of the exhaust hood 2 are. A second position pickup 13 is arranged to put out information on the degree of opening of the shutter 3. The information, in the form of electric or pneumatic signals, is taken to a control unit in which the signals are processed and some of them displayed on an indicator 18, others detected by a limit value circuit 29. The signal quantities thus shown on the indicator 18 are proportional to the air flow speed in the shutter opening of the exhaust hood and when this signal falls below a limit value previously set at the limit value circuit 29, i.e., when the air flow speed in the shutter opening falls below a lowest tolerable value, an optical and/or acoustical alarm is given off by an alarm unit 29, 30, 19, 21. <IMAGE>

Abstract: A subscriber station (1) functioning as a concentrator is connected to subscribers (3) and is connected via trunk lines (4) to a centrally placed transit exchange (5) establishing connections, by reason of a given command, between a source (8) sending special information and a trunk line pointed out as being idle. The subscriber station includes a trunk line economizing apparatus (15-29) investigating each time a subscriber calls the source whether one of the trunk lines is already connected to the source. If no such connection is determined, the source and the calling subscriber are conventionally connected to a trunk line pointed out as being idle, the number of this line being intermediately stored in a memory unit (20) associated with the economizing apparatus. If it is determined at the investigation that the special information is already being transferred to the subscriber station, the subscriber calling the source is connected to the trunk line whose number is intermediately stored in the memory unit. The economizing apparatus includes a circuit (27) for cancelling the intermediate storage when the special information is no longer received by any of the subscribers. Independent of the number of subscribers receiving the special information, only a single trunk line is taken into use, and the central transit exchange is only loaded with a single connection establishment.

Abstract: The refractive index profile of an optical fiber preform is controlled during manufacture by illuminating the gaseous precursor being fed to the preform substrate tube with ultraviolet radiation, measuring the intensity of either the uv that traverses the gas or the induced fluorescence, comparing this measurement with a reference signal, generating an error signal, in response to this comparison, and controlling composition of the gaseous precursor in response to said error signal. A similar technique can be used to control the thickness and refractive index of each layer deposited upon the substrate tube by forming an x-ray shadowgraph of the layers as they are deposited and comparing the shadowgraph characteristics with appropriate reference signals to form a second set of error signals. The latter are then used to fine tune the fabrication process. The invention can also be employed in conjunction with the vapor axial deposition method of fabricating preforms.

Abstract: A fire or explosion detection system for discriminating between radiation produced by a source of fire or explosion to be detected (e.g. a hydrocarbon fire) and radiation produced by a source not to be detected (e.g. an incendiary ammunition and or pyrophoric reaction between an aircraft skin and an inert round) is disclosed. The radiation detectors are respectively responsive to the intensity of radiation in narrow wavelength bands at 0.96 and 4.4 microns. Two threshold units produce respective electrical signals only when the outputs of the detectors exceed respective predetermined values. In addition, a rate of rise unit produces an electrical signal only when the rate of rise of the output of one of the detectors exceeds a predetermined value. An output gate receives these three electrical signals and produces an output to a delay unit which in turn produces a fire or explosion indicating output only when the output of the gate continuously exists for at least a predetermined period of time. It is found that only fires or explosions to be detected will cause the detectors to produce outputs which will maintain the output of the gate for the length of the delay period.

Abstract: The invention relates to an arrangement comprised in a digital group selector of the time-space-time type in a telecommunication system in which the connected subscribers communicate with each other in specially allocated time slots. The group selector comprises time selector modules TSM and space selector modules SPM which are arranged at geographically different distances from each other and from a clock signal unit CLM that provides clock signals to the modules for controlling these. In order to even out the time differences between the different units, at all inputs and outputs connected to time selector modules TSM each space selector module SPM is provided with separate time delay circuits K for compensating for time differences caused by different length of the cables that transmit signals between the clock signal unit CLM and the selector modules and between the different time and space selector modules. The compensating circuits KH, KA, KV contain a number of series-connected registers R, and, by means of looping in these circuits, a delay is obtained corresponding to a particular number of time slots so that the signals from a time stage TSM0 appears at the intersection of the space selector matrix in phase with the clock pulse that the space selector receives from the clock pulse source, and so that the signals that are supplied from an intersection in the space selector to a time stage TSM1 appear in phase with the clock pulse that the time stage receives direct from the clock pulse source. <IMAGE>

Title: LPG level indication in pipe - uses pulsator for pipe wall vibration probe, probe signal processor and digital indicator
Inventor: SINHA BRAJNANDAN
IPC: G01L11/00
Filed: 1982-05-18
Abstract: The appts. involves a pulse unit which causes the vessel's wall to oscillate, and a transmitter which probes the varying oscillatory behaviour dependent upon the degree to which the vessel is filled. In the gas vessel there is an excess pressure which maintains the gas in the fluid phase, and where gas is vacated via a valve, there is renewed gasification to the excess pressure level, with subsequent lowering of the fluid level. The vibrations produced by the pulse unit are damped in frequency and amplitude by the fluid and the excess pressure. The damped wall oscillations are probed by a piezo-electrical detector, and evaluated in a connected processor, the results being presented on a digital type indicator.
