Title: Method of Positional Control of Ion Beams in Mass Spectrometers.
IPC: H01J49/30
Filed: 1968-02-19
Abstract: In a method of maintaining constant the paths of ion beams in a mass spectrometer or in a mass separator, e.g. for separating uranium isotopes, despite fluctuations in the supplies of the magnetic field and of the acceleration voltage, an ion beam which is not utilized in the analysis or separation is collected across the slit of a control collector and the difference in the ion currents received on the two lips of the slit which are insulated from each other is measured and utilized to control the acceleration voltage or the intensity of the magnetic field to cancel the difference in the ion currents. The ion currents are supplied to a differential amplifier to derive an error voltage representing the unbalance of the ion currents. As shown in Fig. 5 the voltages derived from resistors 22, 221 by the ion currents received at 11, 111 are supplied to differential amplifiers 24, 25, the negative inputs of which provide a variable negative feedback serving to balance the gains to that the output voltage E is zero in respect of nominal values of the accelerating voltage and the magnetic field. By measuring the voltage E at 26 this voltage can be set to zero. The voltage E is applied to a dissymmetrical amplifier 29 to provide a voltage E1 with respect to ground. The voltage E1 is then applied to the base of an N-P-N type transistor 30 which operates as a variable resistor in the regulating chain 31 of the voltage supply 35. The voltage at the point O which is therefore dependent on the error voltage E drives the amplifier 34 which regulates the supply 35. Transistorized or vacuum tube amplifiers may be used. The slit control collector assembly comprises, Fig. 3, a stack of metallic and mica strips 8-13 mounted on a carriage 15 which can be adjusted in position along guides 16 by means of a rod and fork mechanism 17, 18. The stack comprises, in order, a stainless steel diaphragm 8 provided with a slit, a mica strip 9 pierced by a rectangular opening, an identical mica strip 10 in which are set two copper strips 11, (111) forming the lips of the collector slit, a further mica strip 12 with a rectangular opening and a copper strip 13 which is connected to ground.

Title: Scanning arrangement in a telephone switching system
IPC: H04M3/26
Filed: 1968-09-21
Abstract: The free or busy state of interstage links of a network SN is tested over resistors R 1 each connected in common with terminals of a resistor R 2 , a capacitor C 1 , and a diode W 1 , one potential E 1 being connected to R 2 and a second potential E 2 being connected to diode W 1 such that an interrogation pulse applied to the capacitor will or will not drive the diode W 1 to conduction according to the potential detected on the associated link of the network. The test resistors R 1 are terminated on crosspoints of R 2 , C 1 , W 1 components in a matrix the rows of which are interrogated to produce test results on column wires. To reduce parasitic capacitance of the columns each effective column comprises a set of m column wires each wire receiving the interrogation results of a set of crosspoints from n matrix rows. Each set of m column wires is commoned over decoupling diodes to one of the single column outlets P 1 to Pk with buffer amplifiers BA 1 to BAk to provide low output impedances. Interrogation is effected from a scanner SC which also scans the rows of a number of other matrices, the corresponding column outlets of all the matrices being commoned to the inputs of amplifiers A 1 to Ak which drive a register REG to record the idle/busy pattern of any interrogated row in any selected matrix as directed from a processor. The potential E 1 is 5 volts, the potential E 2 is 12 volts over a low value resistor and a diode W 2 for each column wire, diodes W 2 preventing spurious outputs due to short-circuit diodes W 1 at the crosspoints. Interrogation pulses from the scanner are 12 volts. Free links are disconnected and allow crosspoint diodes W 1 to conduct when interrogated. Busy links are at a negative potential of a magnitude which varies according to link type resistors R 1 and R 2 being chosen in accordance with the associated link to give zero potential at their junction for a busy link which consequently hold the associated diode W non- conductive during interrogation. Amplifiers BA and A are transistorized, Fig. 2 (not shown). The network SN comprises four stages of relay matrices, a connection being set up by operating a relay in each stage step-by-step from the junctor to the line side of the network. Each matrix has an extra row wire X 1 which is not associated with network links. A periodic interrogation of the associated crosspoints produces readout on all columns and tests the amplifiers A and BA since any missing registration in REG will indicate a fault.

In the separation procedure, the mixture containing 3-cis-dimethylamino-4-phenyl-4-cis-carbethoxy- DELTA 1-cyclohexene and 3-trans-dimethylamino-4-phenyl-4-trans-carbethoxy- DELTA 1-cyclohexene is mixed, in a suitable organic solvent, with oxalic acid or fumaric acid at a temperature up to reflux temperature until the reactants become dissolved in the solvent.

Title: Method of improving the bonding capability of polymer surfaces for subsequently applied coatings, and products thereof
IPC: C23C18/16
Filed: 1973-09-25
Abstract: A procedure is disclosed for modifying the topography of the surface of a polymer substrate to improve the bonding capability of the surface of the polymer in respect to subsequently applied coatings such as metal films, paints and inks. The procedure involved comprises first laminating a sacrificial, anodized metal foil to the substrate surface by heat and pressure, chemically stripping away that foil and then developing preferably, by a supplemental chemical stripping treatment, a network of microscopic fissures and cracks which is believed to incipiently form in the surface by the laminating process. Thereafter the treated substrate may be activated and electrolessly plated by conventional methods, followed by an added electrolytic or electroless plating if desired, to provide a metal film of execellent adhesion. Alternatively, standard vacuum metallizing procedures may be used to provide the initial or finished metal coating. Adhesion of other, nonmetallic, coatings such as paints and inks is also improved by the process.

Abstract: A pulse generator for metal machining by electric discharges, comprising a primary current circuit for producing and transmitting pulse forms to a pair of electrodes. A voltage and/or current source is arranged in the low-ohm and low-loss primary current circuit, the voltage of which has a value which is only that much greater than the operating voltage of the pulses flowing through the spark gap as is needed to positively overcome the voltage losses occurring in the primary current circuit. A signal generator produces a signal corresponding to the desired current pulse shape or form. A comparator, which has a switch arranged in the primary current circuit for regulating the current flow in such primary current circuit, controls the current flowing through the primary current circuit, as a function of the desired pulse form produced by the signal generator and a magnitude of the current flowing in the primary current circuit which is tapped-off by a measuring feeler. A magnetic energy storage arranged in the primary current circuit and having a switch in parallel to the work gap produces a voltage having a value greater than the voltage of the current and/or voltage source, and the primary current circuit is designed such that there is only present stray capacitance.
