Abstract: Abstract of the invention Phase shifter Phase shifters are used in meshed, multi-phase power supply systems (N1, N2) for improving their transmission stability and for load-flow regulating purposes.  In order to be able to use a less costly exciter transformer (1) of lower rating or the tertiary or compensation winding of a system coupling transformer for generating intermediate-circuit voltages (u, v, w) as a function of system input voltages (U, V, W), a resonant circuit (3, 3', 5, 6) is provided between the exciter transformer (1) and an auxil-iary transformer (2).  In this resonant circuit consisting of series-connected capacitors (3, 3') and inductive resis-tances (5) which are connected to taps (7 - 9) between these capacitors and can be switched in and out by means of alternating-current switches (6), tap voltages (u', v', w') are generated which are supplied to the primary windings of the auxiliary transformer (2).  At the secondary windings, connected in series with phase conductors (LU, LV, LW) of the auxiliary transformer (2), auxiliary voltages occur which are superimposed on the system input voltages (UD V, W) and effect the desired phase shifts.  Instead of air chokes (5) which can be switched off, chokes with a ferro-magnetic core or the impedance of a transformer, the secon-dary winding of which can be short-circuited by means of an alternating-current switch, can also be used as variable inductive resistances in the resonant circuit.  The induc-tive resistances (5) can also be star-connected instead of delta-connected.

Title: Piping for use in liquid collection and distribution
Inventor: HIMSLEY ALEXANDER
IPC: B01D24/38
Filed: 1985-02-18
Granted: 1987-06-02
Abstract: Abstract Piping for use in liquid collection and distribution, e.g. in liquid-solid contact vessels, has an extruded pipe having on one side a pair of outwardly-projecting spaced arms each having a re-entrant lip forming a support channel with re-entrant sides extending along the channel.  Channel-section strainer members are slid endwise into the support channel with the sides of the strainer channel being received between the lip and the outer surface of the pipe and with the bottom of the strainer channel, which is provided with strainer slots or perforations, bridging between the support channel sides.  In use, orifices are formed through the side wall of the pipe to communicate with the interior of the support channel to provide for distribution and collection of liquids through the strainer members.  The structure provides a screened slot extending continuously along the length of the pipe, and is easily assembled without requiring special tools.

Abstract: Title:   PROCESS FOR REDUCING SULFUR-CONTAINING CONTAM-INANTS  IN  SULFONATED  HYDROCARBONS,  PRODUCTS          DERIVED  THEREFROM,  AND  LUBRICANTS  AND  FUELS          CONTAINING SAME     Abstract of the Disclosure Processes  of  reducing  the  inorganic  sulfur-containing acid and  the  low equivalent weight organic sulfonic acid content of an acid mass comprising organic sulfonic  components  and  inorganic  sulfonating  agent contaminants  are  described.   In  general,  the  process comprises the steps of (a)  treating the acid mass with ammonia in the presence of water to neutralize the acids in said acid mass and to form a mixture containing the ammonium salts of said acids, (b)  allowing  separation  of  the  mixture  to provide a lower aqueous phase containing water-soluble ammonium salts and an upper phase comprising the oleo-philic alcohol and ammonium salts of the organic sul-fonic acids, and (c)  recovering  at  least  a  portion  of  said upper phase.          The efficiency of the reduction of undesirable materials from the acid mass can be increased by subjecting the recovered upper phase to additional water extractions in the presence of the oleophilic alcohol.        The  ammonium  salts  of  the  organic  sulfonic acids recovered by the above process can be converted to oil-soluble metal salts by reacting said ammonium salts with a basically reacting metal compound in such amounts and under such conditions as to form metal salts of said organic sulfonic acids.  The metals salts prepared in this manner may be neutral metal salts or highly basic metal salts.  The neutral and metal basic salts are useful in a variety of applications including libricants and fuels.

Abstract: ABSTRACT            In a strip for allergy patch testing, the test substance is uniformly distributed in a thin supple film made of a film-forming polymer capable of absorbing moisture from the tested skin area when the test strip is in use.  Prior methods and materials employed for patch tests, in which the test substances are typically unevenly distributed over the skin contact area, are unsatisfactory from the point of view of safety and variability of the amount of test substance applied.  The test strip of the invention has the salutary effects of minimizing the required amount of test substance, thereby increasing the dosage precision, permitting the manufacture of test preparations which are stable in storage, and permitting prefabricated test strips to be made, each containing a plurality of test substance preparations, with little risk of mutual cross-contamination.

Abstract: Abstract of the Disclosure Adaptive Welding Apparatus Having Fill Control Correction for Curvilinear Weld Grooves An adaptive welding apparatus has an optical sensing system for detecting the cross sectional configuration of a weld groove by linearly scanning a monochromatic light source across the groove while viewing the reflected light with a raster scan type TV camera.  A microprocessor receives signals form the camera, computes the weld groove cross sectional configuration, and calculates the area of the cross section.  The angular deviation of the scan path is estimated and corrective calculations are made to compensate for the erroneously large computed area caused by the scan path being skewed from perpendicular to the weld groove.  The microprocessor controls at least one of the wire feed speed, travel speed, and voltage to effect proper weld groove fill characteristics in response to the calculated area.

Abstract: Abstract of the Disclosure:         In a demodulator for use in demodulating a quadrature amplitude modulated signal into a first and a second digital signal by the use of a reproduction of a carrier wave, a puil-in phase is detected by a pull-in phase discriminator (55) after establishment of synchronization.  The reproduction of the carrier wave as momentarily phase shifted in a phase modulator (65, 65') with reference to the pull-in phase to be produced as a phase shifted carrier signal.  The resultant pull-in phase is momentarily corrected to avoid abnormal demodulation.  Detection of the pull-in phase is possible either by monitoring a demodulated analog signal and the first and the second digital signals or by monitoring only the first and the second digital signals.  The phase modulator may be either a two-phase modulator or a n?/2-phase one where n is a natural number between unity and three, both inclusive.

Abstract: There is provided a method of digital Automatic Gain Control (AGC) in a receiver having limited dynamic range, particularly for discontinuous signals. The method is characterized by detecting the level of a received and AGC'd discontinuous signal, comparing the level of the AGC'd signal relative to the dynamic range of the receiver, and adjusting the AGC to establish a desired relationship between the AGC'd signal and the dynamic range limitation. There is also provided a method of handoff in a TDMA cellular-type transmission system utilizing this method of AGControl. The method for Automatic Gain Control (AGC) of discontinuous signals in a receiver having limited dynamic range is further characterized by: digitizing (A/D) a received and AGC'd discontinuous signal and converting the digitized samples to a power sample to sense the power of and detect the level of the signal, comparing the level of the AGC'd signal relative to the dynamic range of the receiver; and coarsely-adjusting by either progressively attenuating the signal until it falls within the dynamic range of the receiver or by progressively gain-amplifying the signal until it falls within the limited dynamic range of the receiver and finely-adjusting the AGC of the received signal until optimum use of the full (albeit limited) dynamic range of the signal processing stages is about 6-12 dB below maximum to establish a desired relationship between the AGC'd signal and the dynamic range limitation. <IMAGE>
