Granted: 1980-01-08
Abstract: ABSTRACT OF THE DISCLOSURE      A method fro producing galvanized metal sheets or strip material having a zinc coating on one side only. The method includes immersing a strip (zinc-coating on both sides) in an electrolyte and passing it between anode means and separate cathode means so as to remove a zinc coating from one side of the strip while simultaneously depositing a substantially equivalent amount of zinc on the opposite side of the strip.  The cathode means is immersed in a separate caustic catholyte solution which is kept separate from the main electrolyte by an anion exchange membrane, supported at least partly within the electrolyte, so as to prevent migration of zinc from the main electrolyte to the catholyte and cathode means and the formation of a deposit on the cathode means.  The method is most economically performed with a steel strip having a differential coating of zinc.

Abstract: Abstract of the Disclosure Disclosed is an asynchronous PCM common decoding apparatus in which a plurality of time division multiplexed digital signals asynchronous to each other are received and decoded.  The apparatus comprises a plurality of receiver units each of which generates at its output a digital signal to be decoded, a channel-number-designating signal for designating the number of the channel to which an analog signal obtained from the decoding of said digital signal is to be fed, and a decode-requesting signal for requesting the decoding of the digital signal.  One or more decoders each produces at its output a status signal for representing that the digital signals given from the receiver unit are acceptable.  A common control unit is responsive to the request signals given from the receiver units and the status signals given from said one or more decoders for successively allotting a combination of a given receiver unit and a given decoder and for sending a data transfer command signal to the allotted receiver unit so that the digital signal to be decoded and the channel-number-designating may be transferred from the allotted receiver unit to the allotted decoder and also for sending a decode command signal to the decoder.

Abstract: TITLE     AUTOMATIC DIRECTION FINDING SYSTEM     ABSTRACT OF THE DISCLOSURE         An automatic direction finding system utilizing the doppler principle for indicating the bearing of a radio trans-mission.  The system includes an antenna array of three or more antenna elements equally spaced around a circular path.          The antenna elements are connected to the input of a receiver through electronically controlled, variable attenuators which are individually adjusted at the same frequency but differing phases so that the array effectively simulates a single anten-na element physically moving along a circular path at a fixed modulation frequency.  The receiver includes a mixer-IF stage with the IF output phase locked to a reference frequency so that the absolute time delay through the IF stage is stabi-lized.  The signal is then frequency demodulated, and the mod-ulation signal is extracted by a narrow bandpass commutating filter.  The phase of the modulation signal is then compared to the phase of the signal controlling one of the variable attenuators to produce a direction indication proportional thereto.

Abstract: ABSTRACT     A collapsible container of the open-platform type for containing goods comprises a generally rectangular platform base having a stub corner post at each corner of the platform base.  At its upper end, each corner post has means for coupling it to a bottom corner portion of a superimposed container.   A corner post is pivotally connected to each stub corner post about an axis substantially parallel to the longer side of the base for movement from a folded-down position in which it lies below the level of the tops of the stub corner posts, through a vertical position into a position slightly beyond the vertical to enable bracing means to be swung upwards and coupled between the two corner posts at each of the two ends of the frame to hold them in their vertical positions.   The tops of the corner post also carry coupling means to enable them to be coupled in their vertical position to the underside of a similar container, the bracing means and the pivotal connections then ensuring that the corner posts remain vertical despite the normal racking loads.

Abstract: ABSTRACT OF THE DISCLOSURE    A camera lens forms an image of an object on an image plane. First and second mirrors produce respective first and second de-tection images of the object on respective first and second arrays of light sensors.  These arrays form portions of an integrated circuit chip.  One of the mirrors is moved throughtout a scanning period to move its image on the corresponding array.  A signal processing circuit receives the outputs of the light sensors and produces an output signal which experiences peaks for certain posi-tions of the moved mirror.  A circuit which receives the output signal produces a pulse for each peak which is larger than all previous peaks in the scanning period.  One of the mirror positions causes the light distributions of the images to be in best corres-pondence on the arrays.  This mirror position represents the existing object distance and produces a maximum one of the peaks, whereby this position produces the last pulse to be produced in the scanning period.  The mirror position which produces this last pulse is represented by the position of a mechanical element or by the value of a mirror signal.  A spring or an electric motor moves the lens into a final position which corresponds to the element position or to the mirror signal.  This position of the lens thus corresponds to the existing object distance, and causes the image of the object to be in focus on the image plane.  Each scanning period and automatic focusing operation may be produced on an individual basis on demand, or these periods may be produced in rapid succession to provide continuous automatic focusing operation.

Abstract: ABSTRACT OF THE DISCLOSURE           This relates to the production of folders such as those commonly used for binding loose sheets of paper into booklet form.  There is provided a method and an apparatus for setting fastener elements, such as tangs and eyelets, into selected portions of a blank made of heavy paper or cardboard.          The apparatus employs rotary die holding elements defining a nip or nips therebetween for receiving one or more portions of a paper blank, particularly a blank folded to a T-shaped configuration.  The apparatus includes means for applying setting forces to the fastener elements during the very brief interval of time that the fastener elements are disposed in the nip or nips between the die holders.  Radially movable dies are mounted in certain of the rotary holders and cam means are employed to apply momentary fastener element setting forces to the fasteners.  These momentary setting forces are applied in such a way that crushing of the leading edge or edges of the fastener elements coming into the nip or nips between the rotary elements is substantially avoided.  The apparatus is capable of operation in a very rapid manner with the tangs and eyelets being positionally matched in accurate fashion and securely installed.
