Patent CA-2072240-A1 (CA)
Inventor: SKALSKI CLEMENT A
IPC: B66B11/02
Filed: 1992-06-24
Abstract: A  semi-active   secondary  suspension comprises  a  relatively  large  actuator  for  handling low-frequency  forces  such  as  those caused  by  uneven passenger distribution, etc., by means, for example, of a position control  loop.  A pair of such suspensions on opposite sides of the car or rail can be made to act in concert, for example, by actuating only one at a time. An inner loop can be added to the position control for each secondary suspension to restore its actuator to a selected preload position when not being used as an actuator. The semi-active secondary suspension is made fully active by adding a relatively small actuator for handling higher frequency dynamic forces. A roller guide embodiment has rollers pivotally mounted on links which are spring-biased toward the rail blades. The relatively large actuators are connected to the  link springs  to  slowly  increase  or decrease the preload force on the spring acting on the links to counter low frequency disturbances. The relatively small actuators also act on the links to ensure that high frequency  disturbances are  quickly  countered  thereby ensuring a substantially vibration-free ride. Suspensions comprising slide guides, electromagnets, etc. are shown.

IPC: H02K16/00
Filed: 1992-08-11
Abstract: Rotor windings are wound on the poles of each of two salient pole-type rotor cores, and the rotor windings on the salient poles axially-aligned on the two rotor cores are connected in series.  A diode is connected across each respective pair of lines connecting each respective axially-aligned pair of poles of the rotor cores.  A plurality of rotor conductors are provided on the periphery of, and extending through, the two rotor cores.  Two stators and two DC magnetic excitation windings surround and face the two rotor cores.  The number of poles of the stator is the same as that of the rotor core, and the number of poles of the DC excitation windings is different from that of the rotor core. A voltage phase shifter is provided to one of the two stators to selectively produce a phase difference of 0° or 180° between the two rotating magnetic fields produced around the two salient pole-type rotor cores.  The motor starts and accelerates according to the principles of an induction motor with a phase difference of 0°.  When the rotational speed of the motor approaches the synchronous speed, the motor is pulled into synchronous operation by having the phase difference switched to 180° and having the DC magnetic excitation windings become operational.  Alternating voltages induced in the rotor windings by the static magnetic fields of the DC excitation windings are rectified by the diodes, and magnetic poles are formed on the two salient pole-type rotor cores.  The motor produces a large starting torque since it starts on the same principle as that of the conventional induction motor and, therefore, does not require any special starting means.  Since the rotor windings function as field windings during the synchronous operation, the motor produces a large torque without requiring maintenance of, for example, brushes.

Title: Screw holder for continuous screwdriver and method of manufacturing the same
IPC: F16B27/00
Filed: 1992-10-13
Abstract: In a screw holder in which bands of synthetic resin are disposed on one side of a series of screws out of alignment with the line connecting the center of each screw to stabilize the feed of the screws by the feed pawl of a screwdriver, the screws are driven in the right position regardless of the presence of the bands.  A series of screws having an enlarged head are held between a pair of bands of synthetic resin.  While a substantially straight main band having a larger cross-sectional area than a secondary band maintains the strength of the screw holder, a secondary band is allowed to bend according to the profile of the screw held therebetween.  The outer surface of the main band is flat, whereas an intermediate part between adjoining screws where the two bands meet is flattened without forming a rib-like projection therein.          Each screw is caused to bite in the main band to reduce the thickness of its bitten part.

Abstract: A pin tenter clamp for a tenter apparatus has a clamp base on which tenter pins are disposed.   The clamp base is provided with  a hinge about which a clamp top plate  is pivotable.  A resilient, elastomeric clamp pad is disposed on a side of the clamp top plate facing the clamp base and tenter pins.  The clamp top plate is biased away from the clamp base to open the pin tenter clamp.  Between the clamp top plate and clamp base is a stripper plate having openings through which the tenter pins may extend when the pin tenter clamp is closed.          The stripper plate also has a resilient, elastomeric clamp pad having openings aligned with those in the stripper plate.  When the pin tenter clamp is open, the stripper plate resides above the tenter pins.  In use on a tenter apparatus, the present pin tenter clamp first holds the fabric to be stretched between the resilient, elastomeric clamp pads before the tenter pins may extend therethrough.   As the pin tenter clamp is gradually opened after the stretching of the fabric,  the resilient, elastomeric clamp pads hold the fabric while the tenter pins are withdrawn, and release the fabric only after this has taken place.

The system accommodates standard stretchers or patient litters, including a first litter positioned in the first station in the rear of the aircraft approximately aligned with but above and behind the second patient station. In order to load the patients into the separate stations, interlockable trays and support plates are used.  An upper tray is initially telescoped within a lower tray which, in turn, is supported on a carriage and lift assembly. The lower tray can be swung relative to the lift assembly to an oblique position pointed toward the exterior door of the helicopter. In addition, the lower tray, with the upper tray supported thereon, can be raised so that the upper tray can be slid rearward into the second station, Each tray has mechanism for locking a patient litter securely in the tray.

Abstract: Abstract Of The Disclosure A process is provided for producing elastomeric compositions by forming a mixture of polymeric material, a reinforcing agent, a processing aid and a vulcanizing agent.  The process of the invention is continuous and includes the repeated, sequential steps of admixing the polymeric material along a first mixing zone defined by a space wherein the gross energy applied induces a first operating temperature range.  The mixture of the first zone is continuously passed into and through a second mixing zone while adding and admixing the reinforcement agent and processing aid therewith, the second mixing zone being defined by a space wherein the gross energy applied induces a second operating temperature range. The mixture of the second zone is then continuously passed into and through a third mixing zone while adding and admixing the vulcanizing agent therewith, the third mixing zone being defined by a space wherein the gross energy applied induces a third operating temperature range.  The mixture of said third zone is the continuously passed into and through a delivery zone to extrude the mixture in the form of the elastomeric composition, with the second and third operating temperature ranges being lower than the first operating temperature range.
