Patent CA-2009866-A1 (CA)
IPC: A44B19/46
Filed: 1990-02-12
Abstract: An apparatus for feeding and transferring discrete coupling elements successively one at a time for attachment onto a stringer tape comprises a feed unit including a vertically disposed feed chute and a transfer unit including first and second slides both supported on a base for horizontal movement effected by a cam means.  The thickness of the first slide is substantially equal to the height of the leg portions of the element.  A pocket is formed in the junction of the first and second slides for receiving an element from the chute and communicates with a slit in the base which provides a suction air for facilitating the fall by gravity of a leading element apart from an ensuing element.  The base includes a transfer chute for receiving one element from the pocket and transferring same onto the tape.

IPC: H05G1/26
Filed: 1990-03-01
Abstract: (1) Abstract Apparatus is provided for use in detecting the input voltage applied to a radiation source operating at an unknown voltage within a given voltage range.  The apparatus includes a set of radiation absorbing filters including a first filter which includes a first chemical element and a second filter which includes a second chemical element. These elements are chosen so that the filters exhibit different radiation absorption characteristics within the given voltage range.  The filters are adapted to be positioned so that the first and second filters are irradiated by the radiation source with the radiation impinging upon a surface of each filter and partially absorbed thereby as it passes therethrough so as to exit therefrom as attenuated radiation.  A detector receives the attenuated radiation passed by the first and second filters and provides first and second signals having magnitudes which vary with the attenuated radiation respectively passed by the first and second filters.  A ratio is determined as to the magnitude of the first signal to that of the second signal with the magnitude of the ratio varying with that of the input voltage.  At least one of the first and second elements exhibits a known K absorption edge within the given voltage range.  Consequently as the input voltage is increased to exceed the known K absorption edge that chemical element exhibits a greater attenuation         (2) characteristic to extend the useful range of the relationship of the magnitude of the ratio and the input voltage.

Abstract: ABSTRACT    The movable electrode of the switching element consists of a flexible compressible contact-mesh comprising conducting and non-conducting wires. The conducting wires extend in the first direction of weaving and are arranged essentially straightlined in a plane. on the other hand, said non-conducting wires, which extend in the other direction of weaving, are bent around said conducting wires, thereby keeping said conducting wires at some distance from a flat electrode contacting said contactmesh. When said contact-mesh is compressed said conducting wires are flexiblely deformed, whereby the wave crests formed on said conducting wires are reaching the surface of said contact-mesh and are contacting there said flat electrode.    Such a switching element distinguishes itself by a simple structure and a flat construction.

Abstract: RF DRIVE CIRCUIT FOR AN ION PROJECTION PRINTING HEAD                   Abstract In order to drive the RF lines (electrodes) of an ion projection printing head or cartridge, driver circuits are provided which generate high voltage, radio frequency signals with rapid envelope rise and fall times so that dots of varying density in accordance with a gray scale may be formed on a rapidly moving dielectric surface.  A separate RF driver circuit for each line includes an active switching device, preferably an FET.  A series resonant circuit is connected across the active device.  This circuit is provided by an inductor connected in series with the effective capacitance presented by the RF electrode of the ion projection head which is being driven.  The inductor and effective capacitance defines a series resonant circuit.  The active device is driven via a pulse amplifier by pulses repetitive at the RF rate and the active device is connected to a power supply, preferably through a parallel resonant circuit which broadens the frequency response characteristic (flattens the effective resonance peak as measured across the RF electrode), so that the current switched through the device is of sufficient magnitude to develop a peak-to-peak voltage across the effective capacitance of the RF electrode of the head to provide sufficiently high peak-to-peak voltage RF cycles.  These cycles may be gated so as to develop ion dots on the dielectric surface having the required gray scale gradiation; the magnitude of the ion charge and the gray scale depending upon the number of cycles of the RF drive voltage used while projecting ions onto the dielectric surface.
