Granted: 1978-11-21
Abstract: Abstract of the Disclosure The invention is directed to a printed circuit board comprising a substrate having a hydrocarbon polymer surface where the hydrocarbon polymer is based upon an elastomeric com-ponent of a conjugated diene polymer such as a polybutadiene, and a thermosetting component such as a phenolic, and where a metal coating is directly bonded by additive plating, including electroless deposition, to at least a portion of the hydrocarbon polymer.  Such circuit boards are characterized by a superior bond between the metal coating and the hydrocarbon polymer and one preparational method involves metalizing the hydrocarbon polymer either in an uncured or partially cured state, and thereafter completing the cure of the hydrocarbon polymer to produce a bond between the polymer and the metal coating of su-perior strength.

Abstract: MULTIPLE FAULT TOLERANT DIGITAL SWITCHING SYSTEM FOR AN AUTOMATIC TELEPHONE SYSTEM                         ABSTRACT        A digital switching arrangement having equipment interconnected to provide multiple fault tolerances in the digital switching of PCM (Pulse Code Modulated) data over time division multiplex lines.  The digital switching arrange-ment includes a set of peripheral units interconnected via a switching network.  The set of peripherals includes input/ output facilities such as digital trunks, analog trunks, and subscriber lines and also includes control processors and related common control equipment.  Peripheral units are connect-ed to the switching network over digital links.  The digital links carry multiplexed PCM data and serve as the exclusive interface between the outside world and the switching network. The multiplexed content of the digital links is further inter-leaved on superhighways within the switching network in such a manner as to uniformaly distribute traffic as well as increase system reliability.  Time-space-time switching is performed between incoming and outgoing superhighways over a modular time-space-time switch.

Title: Process and apparatus for removing metallic ions from an electrolytic solution
Inventor: ZIEVERS JAMES F
IPC: C25D21/18
Filed: 1975-02-17
Granted: 1979-09-25
Abstract: t Abstract of the Disclosure The process and apparatus of the present invention employs a porous cathode electrode made up of fine powder carbon particles held in the form of a porous cake on the upstream side of a perforate substrate by the pressure of the electrolytic solution being forced through the  cake and the substrate.  The cake is initially formed in such the same way a prefilt cake is deposited on a perforate filter element in a pressure filter, and as the electrolysis process is continued, additional powdered carbon is fed into the solution upstream of the cake whereby fresh carbon particles are added to the surface of the cake as the process proceeds.  By using activated carbon, phosphates  and organic molecules may also be separated from the solution and deposited on the interstitial surfaces of the powder d carbon cake simultaneously with the deposition of the metallic ions thereon.  Periodically or whenever the cake is so thick as to impair the operation of the system, the system is shut down; the cake is physically removed from the substrate by any of the ways wall known in the filter art for removing filter cake for filter leaves or tubes; another carbon cake is then deposited on the substrate; and the apparatus is thereafter returned on line.

Abstract: ABSTRACT OF THE DISCLOSURE     An air pumping and scrubbing apparatus which is suitable for use in spray paint booths is described.  This apparatus uses liquid sprays directed into a conduit to cause an air pumping action to inject air into the conduit and discharge to atmosphere using water pressure to move the air so as to avoid the necessity for any moving parts or electrical connections in and around the air stream.  The liquid sprays impinge on mist eliminator strips and are recovered along with foreign material from the air while the air is exhausted downstream of the strips.  A novel transfer plate arrangement is provided between the strips and a sump to minimize foreign material buildup on structural surfaces while allowing stratification in the sump; and novel baffle means are provided to cause a controlled air blowback across the sump to facilitate collection of the floating material therein.

A number of rotary saw blades are arranged in series in the cutting plane of the blades with the cutting depth of each blade being successively deeper.  A number of blocks are pushed along a work bed to the rotary blades by a main hydraulic piston feeder.  At a predetermined point, an auxiliary hydraulic piston feeder grasps the blocks and continues to feed them to the blades.  This enables the main feeder to be retracted to allow a new block to be added and the process is repeated.  This has the advantage of providing for continuous feeding of the blocks through the blades.

The process comprises incubating a serum sample with a solution of 57Co Vitamin B-12, contacting the resulting mixture with a TC-II adsorbent and with a DEAE-cellulose adsorbent for TC-I and TC-III, measuring the total radioactivity adsorbed to said adsorbents, selectively desorbing TC-III from the DEAE-cellulose adsorbent by washing with a monopotassium phosphate solution of about 0.05 M and at a pH of about 4.6, measuring the individual radioactivity adsorbed to each of said adsorbents, and calculating the radioactivity that had been washed from the DEAE-cellulose adsorbent by said phosphate solution.  The resulting four radioactivity values are functions of the total, TC-II, TC-I, and TC-III unsaturated Vitamin B-12 binding capacities, respectively, of the serum tested.

Abstract: ABSTRACT The invention relates to a digital data switch for serially bit-switching word synchronized Pulse Code Modulated (PCM) data from inlets to outlets of the switch.  The switch is particularly intended for use in situations wherein PCM data words arriving at the switch on different inlets are not aligned in so far as word boundaries are concerned.  The PCM data is bi-polar or diphase modulated and the synchronization information of each word consists of a violation of the modulation.  The switch includes a demodulator on each inlet for demodulating the data and a synchronization detect circuit associated with each demodulator for detecting the synchronization information in each incoming data word.  The switch has two functionally identical time division multiplexed switch paths; one being a data path and the other being a by-path for switching the syn-chronization information.  The synchronization information is thereby switched simultaneously through the switch in parallel with the associated data word such that both the data word and synchronization information arrive at the appropriate outlet according to the connection required through the switch.  Each outlet has a modulator for receiving the data word and syn-chronization information and  bi-polar or diphase modulating the outgoing data from the switch and causing an appropriate violation of the modulation in response to the synchronization information.  A method of switching data is also claimed.
