Patent CA-1194992-A (CA)
Title: Mode selector of recording and/or reproducing  apparatus
Inventor: SATO SEIJI

Abstract: ABSTRACT     A mode  selector for selecting a tape stopping mode by separating a pinch-roller from a capstan or a tape running mode by contacting the pinch-roller to the capstan has a plunger solenoid being driven intermittently a pinch-roller lever having the pinch-roller and a driving lever having a eccentric gear. The pinch-roller lever is driven by a first intermittentive operation of the plunger solenoid to become the tape running mode from a normal stapping morde. The driving lever is driven by a second intermittentive operation of the plunger solenoid to be the tape stopping mode, and then the eccentric gear starts to rotate for recovering the pinch-roller lever and the driving lever to a condition of the normal stopping mode.

Abstract: METHOD FOR CLEANING THE DISC SURFACE AND THE HEAD SUPPORT STRUCTURE IN A MAGNETIC DISC DRIVE                 ABSTRACT OF THE DISCLOSURE    In a magnetic disc drive, there is disclosed a method for cleaning the magnetic disc surfaces and the heads.  The heads are loaded and caused to fly on the disc surfaces.  The spindle motor speed is reduced to a speed where the heads fly at approximately 50% of the normal flying height and the head support structure drive motor is commanded to sweep the heads across the disc surfaces, forward and reverse; for several cycles, to remove any particles down to an elevation that is 50% of the normal flying height.  The heads are then positioned over unused tracks on the disc surfaces and the spindle motor speed is reduced to a speed where the heads fly at approximately 25% of the normal flying height so as to scrub off any particles left on the heads.  The spindle motor speed is then returned to normal speed and a 25% margin of interference-free operation has been assured.

Abstract: AIR CELL CUSHIONING PRODUCT, APPARATUS AND METHOD   Abstract of the Disclosure A method and apparatus for the production of air cell cushioning material, for protective cushioning purposes in pack-aging or other purposes, with the air cell product being formed from flexible, single stratum sheet of low density, low melting point thermoplastic, such as low density polyethylene film.  The method and apparatus include an arrangement for cooling an embos-ed film on a rotatable forming drum to a predetermined tempera-ture range prior to applying a sealing laminating film to the cool-ed embossed film, and are such that the apparatus can be halted in its operation without injurious effects to any substantial amount of the air cell product being produced, and can be re-started to again commence production of the air cell product.        The apparatus and method utilize clear thermoplastic single st-racum film, and result in an effective air cell cushioning product which possesses extremely good clarity even after the heat-ing and pressure steps utilized in the production of the product.

Abstract: IMPROVED FLOTATION APPARATUS FOR  CONCENTRATION OF MINERALS  ABSTRACT OF THE DISCLOSURE    The invention relates to the concentration and benefica-tion of particulate matter by froth flotation and in particular to improvements in hydraulic-pneumatic flotation apparatus which contributes to efficiency of operation.  Such apparatus employs a constriction plate which separates vertically arranged flotation and aerating compartments.  A discharge duct may be used to extend through the aerating compartment and to open through the constriction plate centrally thereof.  Orifices in both the constriction plate and the discharge duct are in communication with the aerating compartment to provide a uniform dispersion of air bubbles in the flotation compartment.          To prevent build-up of non-float fraction on the constriction plate, the latter may be dish-shaped toward the discharge opening.  In an alternative embodiment, the discharge duct is omitted and the constriction plate is conically shaped with the apex uppermost.     To minimize development of circulating currents, baffle plates may be used in the flotation compartment.

Abstract: ABSTRACT           In the manufacture of tubing, and particularly finned tubing, for use by the heat transfer industry in the manufacture of heat ex-changers, annealed ends and lands are desirable in certain applications to facilitate the assembly of the tubes to headers and baffles by ex-panding techniques.  Such spot-annealed portions can be produced on a continuous basis by the described apparatus in which the moving tube is passed through a heating chamber which reciprocates on a carriage in the direction of tube movement.  The heating chamber has a pair of spaced, power-actuated clamps which grip the tubing at the ends of a discrete length potion.  The heating chamber and carriage are moved with the tube while it is clamped to provide sufficient heating time to anneal the discrete length portion.  The carriage then returns to its starting position.  Heating of the discrete clamped tubing portion can be by a resistance technique through the clamps or by other tech-niques such as induction heating or gas radiant heat.  If desired, an inert gas can be supplied to the heating chamber to prevent oxidation and/or discoloration.  Also, if desired a quench can be supplied in a secondary chamber positioned on the carriage immediately downstream of the heating chamber to prevent post-oxidation of the annealed tube.

Abstract: Abstract of the Disclosure In an electromagnetic induction heating apparatus according to the present invention, a cooking kettle made of a nonmagnetic metal, which has a conventionally been incapable of magnetic induction heating, is pro-vided with a heating coil which applies an alternating field with a high-frequency level of 50 kHz or more, preferably with a frequency level of 100 kHz or more.          An inverter circuit for supplying the heating coil with a high-frequency current operates in response to an out-put signal from a detector which automatically detects the kind of metallic material of the cooking kettle.  As the high-frequency magnetic field is applied, a skin effect is produced within the metallic material of the vessel, so that the impedance for the magnetic field of the vessel is substantially fixed without regard to the wall thickness of the vessel.

Abstract: NON-ROTATING, TOGGLE BOLT ASSEMBLY             Inventor: Louis N. Giannuzzi, a citizen of the United States of America and resident of Cos Cob, Conn.                      ABSTRACT OF DISCLOSURE      A non-rotating toggle bolt assembly in which a trunnion nut received on the end of a screw whose length exceeds the thickness of the hollow wall for which the assembly is intended, pivotally supports a pair of spring-biased toggle wings.  The wings are normally outstretched; but when the assembly is pushed through a hole drilled in the wall, the wings then fold in against the screw to permit passage therethrough.  On emerging from the hole, the pivoting wings resume their outstretched state at a position well displaced from the inner surface of the wall.  Included in the assembly are locking means which act to prevent rotation of the outstretched wings when, in the course of installation, the operator turns the screw to advance the toggle axially toward the inner surface of the wall to tighten the assembly, and which also acts to prevent loosening of the assembly such as might be caused by vibration, after such installation.
