Patent CA-1120293-A (CA)
Inventor: DAHL WARREN F

Abstract: BLIND FASTENER                         WARREN F. DAHL     AND RICHARD C. LANDT     ABSTRACT OF THE DISCLOSURE        A blind fastener assembly included, in one embodiment a pin, an  expander and a sleeve.  The pin and expander may in-clude, in one configuration, mating threads for drawing the sleeve axially over the expander toward the blind side of a work-piece, or the pin may be a pull-type wherein the portion of the pin opposite from the blind side end has pull grooves which are adapted to be gripped by a conventional pull gun.  The sleeve is a tubular member with a portion of its length having a normal radial thickness and a portion having reduced radial thickness comprising a reduced outer diameter over a portion of its axial length and a counter-bore along the same axial length adjacent one end of the sleeve.  The expander extends through aligned holes in the workpieces and has a tapered nose surface proximate the reduced thickness portion of the sleeve.  When an axial force is exerted on the pin, the reduced thickness portion of the sleeve is forced over the tapered nose surface on the expand-er toward the blind side of the workpiece and is expanded in diameter.  The tapered surface of the expander also deforms and expands the inner diameter of the normal thickness portion of the sleeve where it meets the counter-bore, and when the leading edge of the sleeve contacts the blindside workpiece surface, an optimum shaped, maximum diameter bulb forms in the reduced thick-ness portion of the sleeve against the blindside workpiece sur-face.  When the bulb is fully formed, a reduced diameter break-neck portion of the pin fractures at a predetermined torque or load, leaving a properly tensioned joint.        In another embodiment of the invention, the blind fast-ener comprises a pin and an integral sleeve/expander combina-tion which is designed to fracture at the expander/sleeve inter-face and form an optimum diameter bulb upon axial movement of the pin.  The formed bulb advances along a tapered nose portion of the expander and bears against the blind side of the work-piece clamping the joint together.        In yet another embodiment of the invention, a grip accom-modating feature is provided by a second varying reduced thick-ness portion in the sleeve, located in the normal thickness por-tion between the first reduced thickness portion and the blind-side end of the sleeve adjacent a pulling head on the pin.  Once the bulb is optimally formed and bears against the blind side of the workpiece, additional axial force exerted on the pin causes a second outwardly bulbed portion to form on the sleeve at the sec-ond reduced thickness portion to accommodate variations in work-piece thickness in the joint. The diameter of the second bulb is dependent on the overall joint thickness, with a larger diameter bulb forming for a maximum joint thickness and a  smaller diameter bulb being formed for a minimum joint thickness.

Abstract: Abstract A Storage System Having Bilateral Field Effect Transistor Personalization A storage system, such as a read only memory, is provided which includes field effect transistors each having first and second spaced apart diffusion regions of a given conductivity and a gate electrode, with at least one of the two diffusion regions of selected transistors having a third diffusion adjacent to one of the first and second diffusion regions under the gate electrodes to provide a higher voltage threshold for the gate electrode to one diffusion than for the gate electrode to the other of the two diffusions.  A voltage is applied to the first diffusion having a polarity and magnitude sufficient to neutralize or eliminate the effects of the higher threshold during a first time period and the current flowing between the first and second diffusions is sensed.  During a second period of time the voltage is applied to the second diffusion and the current flow between the first and second diffusions is again sensed.  In this manner two cells or bits of information are stored in each transistor, one at the first diffusion and one at the second diffusion.  Multilevel storing may also be employed by establishing one of more than two predetermined voltage thresholds at each of the first and second diffusions.

Abstract: ABSTRACT      A detachable latch for a container is arranged to snap fit into a latch pocket and operate with minimal or no frictional interference in releasing a projecting bolt member from a closure position wherein it projects through a slot in the container cover.  In a first em-bodiment, the base of the latch member abuts the pocket wall and is restrained from upward displacement by a wing-slot engagement.   A retainer blade projects for-wardly from the upper half of the latch to a location above a retainer shelf of the container body to preclude downward displacement of the latch.  At least one nub projects upwardly from the shelf to provide minimal con-tact with the underside of the blade if the blade is inadvertently lowered into contact with the shelf.  To open the container, the latch is flexed about its base by pushing the upper part of the latch into the pocket, thereby removing the bolt at the top of the latch from the cover slot.  In a second embodiment, the container has symmetrically opposed covers and is served by a single latch having independently flexible halves.

Abstract: Abstract of the Disclosure A digital phase comparator for essentially eliminating the dead zone in the phase correction means of a phase locked loop.  The digital phase comparator is arranged to provide respective up and down output pulses to operate respective charge pumps.  The up and down output pulses at all times are greater than a predetermined time duration no matter how small the phase difference between comparator input signals.  A delay means is provided in the phase comparator logic, which delay means substantially determines such predetermined time duration.  The minimum pulse duration of the up and down signals is selected to be at least of a duration sufficient to operate its respective charge pump, thereby overcoming the finite turn on time of the respective charge pump, no matter how small the phase error.

The system includes several color guns each of which is capable of producing a beam current, with at least one gun for each primary color to be displayed. Several operational amplifiers, each corresponding to a respective one of the guns is provided, each amplifier having an input capable of receiving a video signal which corresponds to the infrared signal and an output.          A feedback loop is connected between the output and the input of each operational amplifier respectively, incorporating in the loop a single color gun which is driven as a feedback element of said amplifier, a result of which is the production of a beam current by each gun which varies linearly as the video signal to the amplifier varies during image production.

Abstract: ABSTRACT OF THE DISCLOSURE        A photographic system for minimizing exposure tracking error under flash illumination using a low-cost camera in which an automatic shutter system constituents the sole control of exposure illumination passed to the film.  The source of flash illumination is a low-cost filament vaporizable flash bulb in which the eff-ective burn time is increased without change in total illumination energy to the maximum interval of exposure time compatible with hand-held camera operation.  The reduced maximum intensity and lengthened burn time reduces the proportionate amount of exposure illumination during shutter closing movement and, consequently, the deleterious effect of variation in shutter closing movement so that exposure with varying camera/subject distances and flash illumination is relatively unaffected.
