Patent CA-1292426-C (CA)
Inventor: GUSTAVSSON LENNART
IPC: B01D/
Filed: 1987-09-17
Granted: 1991-11-26
Abstract: ABSTRACT          The inventive gas cleansing apparatus comprises  a vessel (1) which is partially filled with a liquid bath (32) and which has R gas inlet pipe (12), which leads to a gas dis-tribution means (14) with distribution pipes (18) beneath the surface (34) of the liquid (32). The distribution pipes (18) exhibit inlet orifices (64) for incoming con-taminated gas beneath the liquid surface (34), wherefrom the gas is caused to flow through outlet nozzles, for in-stance venturi nozzles (28), to outlet orifices (31). The outlet orifices (31) are situated at a considerably higher level than the inlet orifices (64). The incoming conta-minated gas will because of its inherent higher pressure press down an inner liquid surface (46) in the distribu-tion  means (14), such that one or more of the inlet orifices (64) are exposed and  thus the gas can flow out through the corresponding outlet orifices (31) with a pressure drop corresponding to the height difference (h) between the outlet orifices (31) and the inner liquid surface (46). During changes in the pressure of the in-coming gas flow the liquid is able to flow out end in through bottom openings (22), thus     the number of operating inlet orifices (64) is automatically adapted to the incoming flow, such that the part flow through each outlet orifice (31) will be substantially constant. This is because that the flow through the outlet orifices (31) mainly is defined by the pressure drop between the inlet orifice (64) and the outlet orifice (31). This pressure drop substantially coincides with the hydrostatic pressure difference (the height h) between the corresponding height levels in the liquid. Since an incoming fluctuating gas flow is divided into a varying  amount of part-streams, such part-stream being substantially constant in size, the cleansing efficiency of the venturi nozzles and gas cleansing liquid bath is substantially independent of the size of the total flow.

Abstract: ABSTRACT                        DIGITAL SIGNAL CODING          A trellis coder has a convolutional encoder (15) which has n states and can progress from a current state to a follower state depending on an input (Y2).  The state progressions are selected such that they can be represented by a diagram having 90° rotational symmetry.  A state transition produces via mapping means (11) by quadrature modulation one of four output carrier signal phases, such that any three state sequence gives rise to a pair of signals having the same phase difference as the pair generated by a corresponding sequence having a position in the diagram rotated by 90° from that of the sequence in question.  Input means (10) enable a single bit data input (Q2) to control the coder state progression so that a given differential output phase always corresponds to the same input bit value.

Title: Bypass element for safeguarding battery cells
Inventor: MEINHOLD HENNER
IPC: H01M50/583
Filed: 1988-06-30
Granted: 1991-11-05
Abstract: Abstract of the Disclosure:           The bypass element is connected in parallel with a single battery cell or a group of battery cells of a high-temperature storage battery including a plurality of series-connected electrochemical battery cells and is used both for balancing the charging state of undamaged battery cells and for the irreversible bypassing of destroyed cells which have failed with high impedence.  The bypass element includes two series-connected semiconductor components, in particular semiconductor diodes, varistors or NTC resistances in each case having a different current/voltage characteristic or curve.  In the event of potentiostatic overcharging of a battery cell, the first semiconductor component goes to low impedance so that the current flow necessary for charging further battery cells is determined only by the leakage current of the second semicon-ductor component.  If a destroyed battery cell fails with high impedance, both semiconductor components break down and irre-versibly short-circuit the cell with a low impedance.

Abstract: A b s t r a c t A container closure formed in its closed state of a springy, elastomeric plastic, to be snapped onto the neck of a container with a ring-shaped retaining portion . The retaining portion     is connected via a hinge      to a re-closable lid    . A tear-off strip is formed in the join between the lid and the retaining portion in the area opposite the hinge     . The strip ' is defined by scoring        to diminish its strength. A seal is provided in the join between the lid     and the retaining portion    , in the circum-ferential sections between the hinge      and the ends of the tear-off member    , said seal being in the form of material bridges  spaced around the circumference of the closure. The tear-off strip     extends along approximately half the circumference of the closure and is connected with substantially rigid joins between the lid     and the retaining ring     so that the closure can be pressed onto the neck of the container without the material bridges     being broken. When the lid     is opened at the hinge      and the bridges     are thus broken, substantially by pure tensile stress, an accoustic signal will be obtained if the bridges     were unbroken.

Abstract: ABSTRACT         There is disclosed apparatus for monitoring the concentration levels of halogen gas in a gaseous atmosphere as confined in an enclosure over a relatively extended period of time   Such monitoring apparatus includes a sensor including first and second electrodes disposed to define a space therebetween through which the gaseous atmosphere flows and a voltage source for applying a voltage between the first and second electrodes whereby an ionization current flows to the first electrode   A control mechanism illustratively in the form of a programmed microcontroller monitors the ionization current collected by the first electrode as the output signal of the sensor  to determine an increase therein as would be indicative of a halogen leak   Upon determining an increase of the sensor output signal above a predetermined difference  the control mechanism removes the energization from the halogen sensor whereby the ionization current is terminated and the life of the sensor extended.  The control mechanism further causes an initial reading of the sensor signal to be taken and to be stored whereby subsequent sensor readings may be compensated by subtracting the stored value therefrom to provide a compensated output indicative of the increased halogen level with respect to the initial background reading thereof   The relatively small halogen sensor output is amplified by a variable gain amplifier whose gain setting is automatically set over a large range of sensitivities
