Patent CA-1289130-C (CA)
Inventor: SAASKI ELRIC W
IPC: H01L23/44
Filed: 1987-05-27
Granted: 1991-09-17
Abstract: Abstract of the Disclosure An integral heat pipe for transferring heat away from electronic components is disclosed.  The heat pipe comprises at least one electronic component mounted to a substrate.  A condenser cap is fastened over the substrate to define a sealed pipe chamber around the electronic component.  The top of the condenser cap facing the component is a condenser surface and is provided with a number of parallel fluted sections.  Each fluted section has parallel vertical sidewalls and a semi-circular top section.  A multi-layered fiberous, porous, wick is located between the condenser surface flutes and the top of the electrical component.  The top of the component may be provided with a number of parallel grooves exposed to the wick.  The pipe chamber is filled with a two-phase working fluid.  The heat generated by the electrical component causes the liquid fraction of the working fluid adjacent the component to evaporate.  The vapor travels to the fluted condensing surface.  The latent heat of vaporization is removed from the vapor so it recondenses and returns to the bottom of the module to repeat the heat transfer cycle.  The wick's capillary pumping action keeps the fluid distributed over the top surface of the electronic component.  The grooved top surface of the electronic component exposed to the wick cause an inverted liquid meniscus to be formed over the component.  This causes the liquid adjacent the top of the component to readily evaporate.

Title: Horizontal press bending using a splitting vacuum/pressure pickup
Inventor: LAMPMAN DEWITT W
IPC: C03B35/16
Filed: 1988-03-03
Granted: 1992-10-06
Abstract: Abstract A horizontal press bending arrangement for press bending heat softened glass sheets during transfer into a shaping station.  The glass sheet is conveyed through a roller hearth or gaseous support hearth type furnace to heat the sheet to its heat deformable temperature.  The sheet is then transferred beneath a vacuum/pressure pick-up to support the glass sheet in non-engaging contact therewith.  The sheet is next deposited on a lower mold.  The vacuum/pressure pick-up thereafter splits in two and moves out of the shaping station to allow the sheet to be shaped between a pair of vertically aligned shaping molds.  After shaping the shaped sheet is removed for further processing, e.g., tempering.

Title: Electrodeposition of high moment cobalt iron
Inventor: LIAO SIMON H C
IPC: C25D3/56
Filed: 1988-05-27
Granted: 1994-05-31
Abstract: ABSTRACT           Ferromagnetic cobalt-iron (CoFe) is electrodeposited on a conductive substrate to form a CoFe thin film.  The wet electrodeposition process disclosed involves use of a relatively low toxic plating bath solution in which the constituents cobalt and iron are introduced as soluable salts.  A lesser amount of iron than cobalt is used to develop an approximately 90% cobalt to 10% iron ratio  in the thin film.  The plating solution also has sodium saccharin, dodecyl sodium sulfate and wetting and buffering agents.  The CoFe thin film that results from using the disclosed process has near zero magnetostriction, acceptable permeability for use as a magnetic head, a highly stabilized magnetic domain and approximately twice the saturation moment of Permalloy?  Magnetic heads fabricated from such film are well suited for use with high coercivity media for high density recording.          * Trade-mark

Abstract: Une porte acoustique comporte un cadre ainsi qu'un premier panneau de gypse monté sur le cadre et recouvert sur sa face externe par une feuille de métal et sur sa face interne par une couche de plomb pour ainsi former une première paroi rigide. Un second panneau de gypse d'épaisseur différente est également recouvert sur sa face externe par une feuille de métal et sur sa face interne par une couche de plomb pour former une seconde paroi rigide. Une bande en matériau flexible adhésive sur deux faces permet de monter la seconde paroi sur l'ensemble cadre-première paroi tout en ne causant aucun court-circuit acoustique entre eux. Les premier et second panneaux de gypse sont d'épaisseur relativement mince tout en assurant aux première et seconde parois une rigidité suffisante, pour ainsi maximiser l'espace d'air entre les deux couches de plomb, lequel espace contient de l'isolation acoustique formé de fibres mises en vibration pour transformer l'énergie mécanique en chaleur. A l'extérieur de la porte, seul un espace périphérique subsiste entre les deux feuilles de métal précitées, lequel est rempli à l'aide d'un scellant de silicone à l'épreuve du feu.

Granted: 1993-02-02
Abstract: ABSTRACT A tool for the controlled, precise movement, in the horizontal plane, of machines such as electric motors, gear boxes, compressors and the like, for the purpose of achieving an accurate horizontal alignment between two or more machines.          The tool includes a clamping arm that has a relatively flat rotatable circular actuator member engaged in a hole in the arm.  The clamping arm has a lip edge to contact the outer edge of an outwardly extending foot of the machine to be aligned, and in the preferred form of the device, the position of the lip edge with respect to the foot outer edge is adjustable by a thumb screw.          The circular actuator member has an offset fulcrum, and rotation of the actuator member around that offset fulcrum causes lateral movement of the clamping arm.  The lip edge of the clamping arm, which is in contact with the outwardly extending foot of the machine being aligned, moves the machine a distance that is a function of the rotational movement of the circular actuator member.

Abstract: ABSTRACT OF THE DISCLOSURE   A low-friction, boat-type, cold-formed rocker arm is provided.  The rocker arm is of generally U-shaped config-uration in transverse cross section throughout most of its length.  An intermediate portion of the rocker arm has a concave interior surface extending there-across with a cen-tral opening through which a shank of a pedestal extends. One end portion of the rocker arm has a concave recess facing downwardly to receive the upper end of a push rod.  The other end portion of the rocker arm has a rectangular opening in the bottom thereof.  An axle extends between side walls of the rocker arm above the rectangular opening and a roller is rotatably mounted on the axle and has a circumferential portion exposed at the rectangular opening. The roller engages an end of a valve stem with rolling, rather than sliding, contact, resulting in lower friction during operation of the rocker arm.

Abstract: Abstract A magazine for housing cartridges, preferably nine millimeter cartridges,  is disclosed and  includes,  as part of the follower assembly, a spirally wound conforce spring  unit,  preferably  comprising  a  plurality  of separate but attached conforce springs.  In a preferred embodiment  the  magazine  includes  a  conventional in-length body,   which has been modified by providing an elongated rib on the inside surface of a first side wall of the body.  A wound portion of the spiral spring unit is located off-center and adjacent to an end portion of a follower body.  An unwound portion of the spring unit is located adjacent to the first side wall of the maga-zine body.  The rib acts to prevent contact between the unwound spring unit portion and the cartridges housed in the magazine.   In a preferred embodiment, the follower body has a substantially compound support surface where-by two adjacent cartridges contact each other and the support  surface  of  the  follower body  to prevent  or reduce rotational-type movement of the follower body. In one embodiment of the magazine a number of latch areas are also provided so that the magazine can be used with different styles of firearms.

Title: Non-interfering method for measuring propagation delay over telecommunications network and apparatus for accomplishing same
Inventor: PAYNE NICHOLAS W P
IPC: H04B3/46
Filed: 1989-06-13
Granted: 1993-08-17
Abstract: ABSTRACT OF THE DISCLOSURE      Methods and apparatus for measuring propagation delay over a line without interfering with data communications over the line are disclosed.  A known signal is sent and looped back over a secondary channel, and the loop time is measured.          Because the known signal is sent at a non-interfering frequency at the edge of the passband, the loop time minus fixed delay times of the communicating means does not provide a true measure of propagation delay.  Rather, the envelope delay distortion must be determined and also subtracted from the loop time.  The envelope delay distortion is determined as a function of the utilized non-interfering frequency and the line length, the latter of which may be estimated from the loop time.
