Patent CA-1276493-C (CA)
Title: Pressure roll for use in calenders and the like
Inventor: PAV JOSEF
IPC: F16C13/00
Filed: 1987-08-11
Granted: 1990-11-20
Abstract: PRESSURE ROLL FOR USE IN CALENDERS AND THE LIKE              ABSTRACT OF THE DISCLOSURE           A pressure roll for use in calenders has a stationary carrier for a shell which is rotatable and movable radially of the carrier.  The end portions of the shell surround antifriction bearings which, in turn, surround sleeves capable of moving radially of stubs constituting the end portions of the carrier. The sleeves are pivotally connected to the carrier for oscillatory movement about an axis which is parallel to the axis of the carrier and is angularly offset from one or more hydrostatic or otherwise configurated supporting devices operating between the carrier and the shell to change the radial position of the shell and/or to change the shape of one or more selected portions of the shell.  Pivotal mounting of the sleeves on the carrier reduces friction and facilitates accurate adjustment of the radial position of the shell with reference to the carrier.

Title: Load compensated valve
Inventor: BUDZICH TADEUSZ
IPC: F15B11/05
Filed: 1987-10-21
Granted: 1990-11-27
Abstract: Abstract of the Disclosure Load Compensated Valve A load responsive system including individual positive and negative load compensators, for control of positive or negative load and an external logic system for determination of whether the controlled load pressure is positive or negative.  The deactivating valve deactivates the positive load compensator, when the negative load pressure exceeds a certain minimum predetermined level, preventing flow of fluid from the system pump to the system actuator controlling a negative load at a pressure higher than a certain predetermined level, and therefore preventing development of excessive pressure in the actuator, while also deactivating the negative load compensator below a certain minimum predetermined negative load pressure level and while the positive load is being controlled by the positive load compensator.

Patent CA-1286138-C (CA)
Inventor: LEIN JUERGEN
IPC: G03B27/60
Filed: 1987-12-15
Granted: 1991-07-16
Abstract: ABSTRACT OF THE INVENTION           An automatically operated vacuum feed system for cameras is disclosed.  Such system includes an opaque, flexible transport belt that is secured between rollers situated at opposite sides of the platen of the camera. A manifold is secured to a vacuum pick-up bar that is adhesively joined to the transport belt, and a central bore and depending channels are defined in the bar.          The channels are aligned with openings passing through the belt so that suction forces can be introduced to the underside of the belt to cause photosensitive materials to adhere thereto.  The pick-up bar is suspended between a pair of C-shaped tracks that is secured inboard of a pair of side frames for a rigid belt frame.  Lift links join the tracks to the side frames, and a lift motor period-ically elevates the tracks, thus lifting the manifold and the belt.          A reversible motor, a drive sprocket, idlers, and an endless chain are situated outboard of one of the side frames.  The motor drives the sprocket which drives the chain in one direction, and then the other.  This motion is mechanically transmitted to the rollers for the transport belt and causes them to pay out, or take up, the transport belt.          The transport belt, without the intervention of a human operator, picks up, advances, raises and lowers, a sheet of photosensitive material relative to the platen of the camera through a series of distinct, operational steps.  The emulsion side of the photosensitive material is not marred, and exposures of increased clarity are obtained.

Title: Increased bandwidth for multi-processor access of a common resource
Inventor: CONFORTI JOSEPH A
IPC: G06F13/14
Filed: 1988-02-01
Granted: 1992-02-11
Abstract: INCREASED BANDWIDTH FOR MULTI-PROCESSOR ACCESS              OF A COMMON RESOURCE ABSTRACT OF THE INVENTION This circuitry permits equal access to a shared resource by a number of central processing units (CPUs).  In a multiple CPU arrangement, common resource contention problems arise, when several CPUs attempt to access the common resource. To resolve these contention problems, this circuitry is an improvement to arbitration ring circuitry.  The circuitry of this invention permits each of the CPUs equal access to the common resource during situations in which each CPU is constantly generating requests (high bandwidth utilization) for access to the common resource.  This invention is particularly useful for systems in which a large number of CPUs must have their local memory rapidly reloaded from a common memory source.  Reloading procedures for large numbers of CPUs require up to an hour.  By employing the present invention, these reloading times can be cut from one hour to approximately 5 minutes.

Abstract: ABSTRACT OF THE DISCLOSURE:     There is disclosed a circuit breaker overcurrent tripping device.  This tripping device includes: a fixed iron core accom-modating a bimetallic strip in which a flow of an electric cur-rent is present, the bimetallic strip bending when an overcurrent is present; a movable iron core attracted to the fixed iron core when the electric current becomes a short circuit accident cur-rent; a tripping mechanism operated both by the movement of the movable iron core or the bending of the bimetallic strip; a fixed contact point connected via a connecting wire to a load terminal; a movable contact point fixed to the movable iron core and con-nected via a conductor wire to a fixed end of the bimetallic strip; and a flexible conductor for connecting a free end of the bimetallic strip to the load terminal.  In this configuration, the fixed iron core is wound with at least one turn of the flexi-ble conductor, thereby increasing the magnetic force attracting the movable iron core to the fixed iron core.  A shunt circuit is formed when the movable iron core contacts the fixed iron core, thereby reducing the current overload on the bimetallic strip, and preventing the bimetallic strip from damage.
