Patent CA-1113409-A (CA)
Inventor: BROWNETT ROBERT L
IPC: F16D41/08
Filed: 1980-01-16
Granted: 1981-12-01
Abstract: ABSTRACT       An anti-reversal device is provided whereby a wheel and shaft are free to rotate in one sense relative to a stationary member but are prevented from counter-rotating in the sense by engagement of load-bearing pins between teeth of the respective members.  The pins are positively driven to the operative positions in which they are shown by a control ring which is free to rotate with the wheel in the permitted sense but prevented from rotating in the other sense by the engagement of secondary pins?between teeth on the inner periphery of the control ring and secondary teeth on the stationary member.  If the wheel tends to counter-rotate in the sense the teeth of the wheel drive the pins down the slots in the arrested control ring to their operative positions.  When rotation of the wheel re-commences in the permitted sense the tendency of the con-trol ring to lag behind causes the pins to be displaced to the radially outer ends of the slots so that there is no friction between the pins and the teeth of the stationary member.  In a modification the secondary pins, the secondary teeth on the stationary member and the recesses in the inner periphery of the control ring are dispensed with and their functions are performed by additonal pins between the teeth and located in slots in the control ring which have an opposite inclination to the remaining slots.

Abstract: ICl 4542 June 1, 1979 IMPROVED STEAM STERILIZATION INDICATOR                             ABSTRACT     An improved steam sterilization indicator is provided.          The indicator includes a fusible material, in tablet form, depos-ited in an embossment in one end of a thin aluminum backing.  A wicking strip is attached to the backing with one end of the strip being in close proximity to the fusible tablet.  A clear plastic material covers the tablet and the strip and is adhered to the backing.  The melting point of the fusible tablet is depressed in the presence of saturated steam.  Upon melt, the material in the tablet is absorbed by the wicking strip, produc-ing a color front to provide an indication of the integration of time and temperature in the presence of steam.  Various amounts of a binder are used in the tablet to provied a device which may be adjusted to reflect the thermal death curves of various types of microorganisms.   The cover and the wick are bonded to the backing by an acrylic adhesive which also affects the rate of the indicator.

Abstract: ABSTRACT A method of/and apparatus for removing the front and rear segments of a rolled wire or wire rod which is fed in the form of winding packages to a collecting device and which is subdivided by separating procedures into good stock and into scrap windings.  The scrap windings may be separated by cutting movements which correspond substantially to the transporting movement of the winding packages.  The windings of each winding package may be briefly taken along by rotating cutters which periodically simultaneously carry out a cutting movement.  The scrap windings of the rear segment and those of the front seg-ment of the succeeding or subsequent winding package may be simultaneously separated with the cutting procedure.  A guide-pipe element movably supports windings of the winding packages in the longitudinal direction.  The windings spirally or helically surround the guide-pipe element.  Several cutting wheels rotate in the region of the upper surface of the guide-pipe element.  The cut-tingwheels, together with counter knives, which stand still during the cutting procedure, form a separating device.  Also provided is a stop element which is shiftable between the scrap windings and the good windings.  The peripheral speed of the cutting wheel and cutters corresponds at least substantially to the transporting speed of the winding packages.  The cutting wheels of the separating devices are driven by a common drive unit.  At least the cutting wheels of the separating devices are connected with the pertaining drive unit. The guide-pipe element may be surrounded by three separating devices.  A stop element, an intermediately connected adjustable time member or timer, and the counter knives are controlled by at least one sensor unit which operates free of engagement or free of contact therewith and which generates at least one control impulse as a function of at least one predetermined winding number --from which the number of scrap windings to be removed is derived.  The counter knives are arranged coaxial to and adjacent to the pertaining cutting wheel.

Abstract: PHF. 79-589                15 ABSTRACT:           Apparatus for detecting the closure of a sub-scriber's telephone line in the presence of an alternating ringing voltage superimposed on a direct voltage comprises device for producing a unidirectional current from the com-bined alternating and direct voltages.  When the line is open no direct current will flow and hence the peak value of successive half cycles will be equal whereas when the loop is closed and direct current flows the peak values or successive peaks will be different.  A capacitor is charged by a voltage U1, which is proportional to the combined voltage, through a transistor provided that the voltage U1 is greater than the voltage across the capacitor and discharged through a resistor.  The time constant of the discharge cir-cuit is selected so that when the line is looped the smaller peak is lower than the voltage to which the capacitor is discharged and hence charging current flows into capacitor on alternate peaks of the voltage U1 only.  The intervals between pulses of charging current are determined by com-parator which provides an output S which indicates whether the subscriber's line is closed.

Abstract: Abstract of the Disclosure A passive system having high volumetric compliance in response to compressions and expansions, such as are present in low frequency acoustic wave energy, employs a saturated vapor-saturated liquid interface thermodynamically stabilized by distributed heat sinks that interact with the acoustic wave energy.  The volumetric compliance of a system, such as a loud-speaker enclosure, is significantly increased by utilizing a spatially distributed mass of fine fibers thoroughly wetted by a liquid, to provide thin liquid sheaths on the fibers that are in good thermal interchange with the fibers themselves and also with the vapor molecules in the spaces between the fibers.  The liquid preferably has a low heat of vaporization, a high vapor pressure at the ambient temperature and a low rate of pressure change with respect to temperature.  The liquid sheaths and fibers serve as high surface area heat sinks having a short thermal transport distance to supply the alternating heat attendant to evaporation and condensation.  The fiber masses are preferably disposed in thin layers separated by communicating channels, so that the interaction takes place substantially uniformly within the volume occupied by the fibers, without substantial dissipation of energy in any concentrated region.  With this system, at least one additional liquid having a high thermal mass may be employed in distributed fashion, further materially increasing the efficiency of the system and augmenting the volumetric compliance of the system.

Abstract: ABSTRACT An improved engine construction is disclosed having a valve train including valves and corresponding valve stems for controlling the intake and exhaust ports, cams for imparting reciprocating motion to the valves by way of the valve train, and a valve spring for biasing each valve toward its closed position and the valve train into tracking relation with the cam.  The only element of the valve train coupling a cam to a stem is a cam follower with a depression for receiving the corresponding stem end and a cam engaging surface opposite the depression with the cam follower being held captive intermediate the stem and cam solely by the spring biasing of the stem toward the cam and the engagement of the stem end and the depression.  The spring biasing is provided by a coiled wire spring having outwardly extending legs each of which engages a corresponding stem to urge the valves toward their closed position.  The bight or coiled portion of the spring is held in a relatively fixed position by a portion of the engine casting.  Another feature of the engine resides in the engine block casting which includes an exhaust gas passageway extending from an engine cylinder and including near the end thereof remote from the cylinder an enlarged cavity which defines at least a part of a muffler shell.  Numerous other elements may be cast integral with the engine block including a boss for attaching a pull rope recoil starter assembly along with an anchoring point for one end of the rewind spring of that starter assembly and retaining guides for the rope of the starter assembly.  The locator, such as a stud for the intake and exhaust poppet valve biasing spring, may also be cast integrally with the engine block.  A further feature of the engine resides in a combination crankcase breather mechanism and oil fill cap which due to its remote location from the engine crankshaft as well as the tortuous air flow path through the cap to the atmosphere minimizes the egress of oil from the engine through the breather mechanism.

Abstract: : On sait qu'une batterie d'accumulateur de véhicule automobile n'a généralement pas de facilité pour le transport, que son montage sur un véhicule est peu pratique et le branchement au système électrique du véhicule à l'aide de connecteurs en plomb serrés par des vis, qui se corrodent rapidement, rend le démontage et l'emport problèmatique, dangereux et rebutant. Dans la présente invention on se propose de modifier une batterie de façon à simplifier et faciliter son montage et démontage d'un véhicule, ainsi que son transport par l'adjonction de deux éléments complémentaires l'un à la partie supérieure de la batterie appelé " cadre " l'autre au véhicule appelé " caisson ". Le cadre comporte une poignée constituée d'une cordelette fixée sur ses côtés latéraux, des courroies pour le fixer sur la batterie des contacts reliés aux bornes de la batterie par des connecteurs, et des crochets destinés à le verrouiller au caisson et dont l'effacement est provoqué par la traction exercée sur la poignée pour soulever la batterie. Le caisson sorte de boîtier de dimension suffisante pour que l'on puisse y insérer la batterie fixée à son cadre, il comporte: des contacts destinés à rencontrer ceux du cadre et reliés au système électrique du véhicule, des prévisions pour le fixer au véhicule, ainsi que des points d'ancrage pour les crochets du cadre. De cette façon, le verrouillage et le branchement électrique sur le véhicule sont simultannés à la dépose de la batterie, commodément portée par la poignée du cadre, dans le caisson fixé au véhicule. Il existe sur le marché des dispositifs destinés à améliorer le transport des batteries ils sont peu nombreux et pas toujours fiables. Ils sont en général constitués d'une lanière que l'on attache temporairement aux bornes de la batterie. Ces dispositifs sont peu sécuritaires car il arrive fréquemment que l'attache glisse, et la batterie tombe se brisant en général. Il existe aussi une petite série de batterie légère munie de cordelette servant de poignée, ces batteries de par leur faible capacité se prêtent mal à l'usage sur véhicule automobile. De toute façon ces dispositifs ne tentent qu'à faciliter le transport, il n'en existe aucun qui combine le transport, la fixation et le branchement sur le véhicule en une seule opération celle de sortir la batterie de son logement à l'aide de la poignée pour la retirer du véhicule, et pour la reposer simplement dans son logement.
