Abstract: ABSTRACT        A new class of natural antioxidants consists of extracts of plant matter containing hydrolysable gallo-tannins.      These gallotannins may be in the form of a crude extract which is obtained by extracting the plant matter with a water-miscible solvent, evaporating the solvent under vacuum and drying it.  The crude extract may be purified by taking it up in a mixture of organic solvent and water, separating the organic phase, evaporating the solvent under vacuum and drying the residue to obtain mainly tannic acid.      The purified extract may then be hydrolysed in a mixture of methanol and water at a pH of from 6 to 8, the hydrolysate extracted by an organic solvent, the solvent evaporated under vacuum and the residue which contains mainly pentagalloyl glucose may be dried.      The plant extracts have good anti-oxidant properties, while being neutral from the point of view of colour, taste and smell, this not being the case with the extracts of spices.

Abstract: DYNAMIC MEMORY CONTROLLER FOR  SINGLE-CHIP MICROPROCESSOR          Abstract of the Disclosure A controller for interfacing a single-chip microcomputer with external dynamic random-access memory, includes a subcircuit for generating a column-address strobe at a time after a row-address strobe is generated, and also includes a multiplexing subcircuit for providing the proper 8-bit portion of a 16-bit address output from the microprocessor to the 8-bit dynamic memory inputs, prior to receipt of the associated row-address or column-address strobe. The microprocessor utilizes the strobe-generation and multiplexing subcircuits to burst-refresh the dynamic memory, in one presently preferred embodiment.  In another presently preferred embodiment, lines from an additional microprocessor output port are utilized with a resettable binary counter and a multiplicity of buffers, to count through the range of row addresses in cyclic fashion, with each address being incremented after the previously-addressed row of memory cells has been refreshed.

Abstract: SOLUBLE POLYACETYLENIC AND POLYAROMATIC POLYMERS          AND METHOD OF MAKING THE SAME                 ABSTRACT OF THE DISCLOSURE   A soluble polyene polymer and a method of making the same are disclosed.  The polymer is of the class suitable for doping to produce an electrically conductive polymer. The  method  is  generally  applicable  to  acetylenic  and aromatic  monomers.  proven  examples  of  which  include acetylene,   benzene,   anthracene   and   napthalene.    In accordance with the method,  the monomer is dissolved in arsenic   trifluoride.    Arsenic  pentafluoride   is   then introduced into the solution to induce polymerization by what   is   speculated  to  be  an  ionic  polymerization reaction.   The  resulting  polymer  differs  from  other polyene polymers in that it is soluble in common organic solvents,  and further  in that  it can be melted without undergoing    decomposition,    thereby    rendering    it particularly  suitable  for processing  to  form  various polymeric articles.

Abstract: Abstract Vibration Sensor And The Method Of And Apparatus For Manufacture Thereof An improved method and apparatus are provided for making vibration sensors, particularly of the type  used  in  automotive  applications  wherein  a piezoelectric element is affixed to a flexing plate which is mounted on a support stem in "umbrella" fashion.   A desired resonant vibrating frequency of the sensor is obtained by progressively working a neck portion of the support stem, as by peening, to effectively decrease the vibrating radius of the plate and thus increase its resonant frequency toward and to a desired resonant frequency.  The plate's frequency is monitored and the working of the stem neck portion is terminated when a desired resonant frequency is attained.  An inclined support shoulder on the stem below the neck portion facilitates the aforementioned manufacture.   An undercut positioned in the stem neck portion near its transition into the support shoulder further facilitates the manufacture.

Abstract: VEHICLE POWER WINDOW CONTROL CIRCUIT          Abstract of the Disclosure A control circuit for a one-touch vehicle window control uses a pair of switches, each switch actuating a still window for movement in one of two opposite directions but being effective to stop a window moving in the opposite direction from that which it initiates.  The motor is in an H-switch bridge with SCRs and FETs, with each switch providing actuating signals to an SCR and FET for one armature current direction and further providing an actuating signal through an impedance to a discharge transistor connected across a capacitor connected to the gate of the FET for the opposite armature current direction. The base of each discharge transistor is connected to another capacitor and through another impedance to the junction of a FET and a motor armature terminal.  Each connected pair of impedances forms a voltage divider to turn off a FET upon the detection of motor stall current therethrough; and the impedances further act to ensure the non-conduction of the non-activated FET to prevent a short circuit of the power supply.

Abstract: Abstract Described is a pulse radar apparatus having a repetition period containing m wobbles. The pulse radar apparatus is provided with: a transmitting an receiving unit (2), whereby the received target echoes are sampled and digitised; an n-point DFT processing unit (3); a threshold circuit (4); and a cluster combiner circuit (5) comprising means to form a cluster covering one single target using the signals obtained from the threshold circuit (4). Due to the wobbles, additional information arises in the DFT spectra: From the range, azimuth, local maximum values of the DFT spectrum and the associated output channel number of the DFT processing unit (3), a classification unit (6) determines whether a target is a multiple-time-around target. The classification unit (6) is also able to determine the target doppler frequency, even if this frequency exceeds the average pulse reptition frequency.

Abstract: An integral phase shifting network (215,216,217) of a transmitter filter (104) provides a means to reduce the size and increase the efficiency of an antenna coupling network. The network to shift the phase of the transmitter filter (104) is printed by depositing conductive material directly on a ceramic block (230) using low-loss circuit elements and can be tuned easily by removing conductive material if required in certain applications. By utilizing an integral phase shifting network (215,216,217), either transmit filter (104) or receive filter (112) having a highly reactive and capacitive out-of-band impedance in the receive or transmit band, respectively, can be connected to a common antenna port without external transmission lines.
