Abstract: CONTROL VALVE DEVICE FOR VEHICLE AIR SPRINGS               ABSTRACT OF THE DISCLOSURE This invention relates to a mechanical or magnetic-actuated control valve device for so controlling pressure of fluid in an air spring for interposition between a sprung portion and an unsprung portion of a vehicle as to support the sprung portion at a substantially constant preselected height relative to the unsprung portion irrespective of the load carried by the sprung portion.     A supply valve and a release valve are operated by either mechanical or electro-magnetic actuators by a cam to supply fluid under pressure to or release fluid under pressure from the air spring accordingly as the cam is rocked in one direction or in an opposite direction from a neutral position.     Actuation or rocking movement of the cam in either direction from its neutral position, resulting from movement of the sprung portion relative to the unsprung portion in response to a change in the load on the vehicle, effects shifting of either the mechanical or the electro-magnetic actuators to cause operation of the proper valve to effect a change in the pressure in the air spring that is propor-tional to this degree of rocking and therefore the degree of change of load on the vehicle.

Abstract: APPLICATION FOR CANADIAN PATENT     SPECIFICATION               ABSTRACT OF THE DISCLOSURE     The tool change mechanism includes a tool storage magazine having a plurality of tool storage sockets disposed in two concen-tric circles.  A tool transfer arm is mounted within the inner circle of sockets.  The transfer arm may be rotated and extended or retracted and moved toward and away from the magazine for ex-tracting a previously used tool from a ready socket and inserting such tool into a designated socket of the magazine.  In like manner, the transfer arm will operate to extract a selected tool from any one of the sockets in the magazine and transfer it to the ready socket.  The latter is mounted on a carrier which also supports a tool change arm.  The carrier is pivotable between a loading posi-tion and a tool change position.  When the carrier is in the load-ing position, the ready socket is located at the magazine where it is accessible to the tool transfer arm for extracting previously used tools from the ready socket and inserting new tools into it.   On the other hand, when the carrier is in the tool change position it is located adjacent to the spindle in position to enable the tool change arm to interchange tools between the ready socket and the spindle.

Abstract: In re application of James M. Gasier and William E. Currie For SWAGING APPARATUS                     ABSTRACT OF THE DISCLOSURE         A swaging apparatus in which a pusher member pushes a hose coupling sleeve having a hose end portion therewithin down-wardly into a die cavity of a closed die defined by mating seg-mental die members in a retainer to radially deform said sleeve into gripping engagement with said hose characterized in that upward retraction of the pusher member automatically opens the die by effecting upward and lateral separating movement of said die members thus to release the swaged hose-coupling assembly for downward discharge from between the separated die members and through said retainer.  The swaging apparatus is further character-ized in that before the pusher member commences its downward swaging stroke on the next unswaged hose-coupling assembly inserted up-wardly through the retainer and between the separated die members, the latter are released for movement by gravity into mating engage-ment within said retainer.  The swaging apparatus is yet further characterized in that the opening of the die entails a prying (or a tearing away or tilting) motion of the segmental die members to facilitate stripping of the die members from the swaged hose-coupling assembly.

Abstract: LARGE BURNERS, PARTICULARLY FOR LIQUID FUELS     ABSTRACT OF THE DISCLOSURE     A burner for liquid fuels such as light, medium and heavy oil, in which a fuel supply pipe is concentrically located in an air supply pipe and partially enclosed by a sleeve carrying air.  A spray diffuser and a twist-producing member encloses the fuel supply pipe upstream of the spray diffuser.  The twist-producing member has a fixed blower wheel and receives combustion air from the periphery thereof.  The combustion air quantity is regulatable upstream of the burner head as a function of the prevailing fuel flow.  A space located between the twist-producing member and the air supply pipe, holds two additional air supply pipes.  One of these additional air supply pipes, an innermost pipe, has an end cone directed towards the outside.  Coaxially downstream from the twist-producing member enclosing the fuel supply pipe, there are two additional twist-producing members with opposite twist di-rection enclosing each other.  One of these additional twist-producing members is an inner member having a twist direction corresponding to the twist direction of the first-mentioned twist-producing member.  The smallest diameter of the inner twist-producing member is connected to an axial discharge opening of the main or first-mentioned twist-producing member enclosing the fuel supply pipe.  The largest diameter of the outer twist-producing member is located between a cylindrical part of the inside air supply pipe and its outward directed end cone.  A sliding link closes, at partial load of the burner, the intake to the other twist-producing member which is the main member enclosing the fuel supply pipe, the space between the two additional air supply pipes, and the intake to the outer twist producing member, whereas the sliding link opens these elements in other load regions of the burner.

Abstract: TEMPERATURE-DEPENDENT ACTUATING MECHANISM                 Abstract of the Disclosure There is provided a temperature dependent actuating mechanism that may be used to control a valve in a pipe line depending on the temperature of the fluid flowing in the line.  The mechanism includes a temperature responsive sensor including a variable volume chamber which is in fluid communication with an actuator that is contained in a variable volume member connected with an operating member of the actuator to move the operating member responsive to changes in volume of the variable volume member.  Connected with the variable volume chamber is a temperature responsive means such that a change in volume thereof caused by a temperature increase increases the volume of the variable volume chamber.  Fluid then flows out of the actuator chamber, and the volume of the variable volume member increases with resultant movement of the operating member.

Abstract: ABSTRACT OF THE DISCLOSURE             A detector circuit for color television receivers having a pair of transistors whose emitter electrodes and collectors electrodes are connected together, respectively.  An ACC detected output is obtained from the collector electrodes of the pair of transistors through an integrator circuit. A reference voltage is supplied to the emitters of the transistors which are connected together so as to provide a threshold voltage and differential input signals which are opposite in phase with each other are applied to the base electrodes of the transistors, respectively.  At the output terminal of the detector circuit there is produced such a signal which corresponds to a full-wave rectified signal of the portions of the differential input signals exceeding the threshold level, and the full-wave rectified signal is made as a DC signal by the integrator circuit. This DC signal is then used as a gain control signal for, for example, an ACC amplifier.

Abstract: ABSTRACT OF THE DISCLOSURE A method and apparatus for packaging compressible fibrous batts and a package of same are provided.  The batts are formed by severing a longitudinally-extending strip of compress-ible fibrous material into batts of discrete lengths with the batts then being collected in end-to-end relationship.  The batts are then moved into a loop of a packaging machine, which loop is formed by a belt maintained under controlled tension.  The batts are fed longitudinally in abutting, end-to-end relationship into the belt loop which places them under compression as they are wound into a package, with the loop gradually expanding in diameter as the package size increases. Tapes are placed directly around the outermost batt to hold the package in the compressed state and the completed package is then discharged from the machine.
