Abstract: In a panel shutter assembly including a plurality of shutter panels which are movable up and down along a pair of transversely spaced upstanding guide rails, a pair of chains to which the panels are fastened one after another, a set of sprockets engaging the chains for moving the chains in either direction to move the panels to open and close a shutter opening, and a pair of panel supporting rails from which the panels are suspended in a panel storage space when the shutter opening is opened, the sprockets consist of a pair of first sprockets for moving the panels up and down and a pair of second sprockets spaced horizontally apart from the first sprockets and provided between the first sprockets and the panel storage space for moving the panels horizontally, and the panel supporting rails extend horizontally.  The horizontal supporting rails enable a reduction in height of a box defining the panel storage space.  A guide plate or plates can be provided in the box for holding each chain to ensure its horizontal movement between one of the first sprockets and one of the second sprockets and thereby the smooth movement of the panels in the box.  Each of the second sprockets can be formed between the roots of every two adjoining teeth thereof with a semicircular recess in which the link pins of the corresponding chain are engageable, so that the chain leaving the second sprocket for the panel storage space may form a U-shaped sag to ensure that all the panels be properly retracted into the panel storage space.

Title: Lamination of integrated circuit packages
Inventor: PARK WILLIAM O
IPC: H01L21/50
Filed: 1991-02-12
Abstract: LAMINATION OF INTEGRATED CIRCUIT PACKAGES             ABSTRACT OF THE DISCLOSURE      Laminated   integrated  circuit  package  are prepared using   an   apparatus  and  process  that consolidates  the  package  without the use of fluids and  nonconforming  dies.    A plurally of laminates from  which  the  package  is formed are stacked on a base.    A  pressure  transfer  membrane  having  two layers,  a silicone rubber release layer adjacent the stack  and  a  urethane  rubber  separating layer, is placed   over  the  stack  of  laminates.    A  solid pressurizing  medium, preferably a body of Sorbothane retained  by  a latex diaphragm  in  a  cavity in a pressurizing  tool,  is  pressed against the pressure transfer   membrane   and  the  underlying  stack  to consolidate  the  stack  of  laminates.   Preferably, heat  is  applied  simultaneous  with the pressing to aid  in  consolidation,  and  the  region between the pressure   transfer   membrane   and   the  stack  of laminates  is evacuated  to  remove air bubbles that might locally prevent lamination.

Title: Straw spreader for a combine harvester
Inventor: HALFORD JAMES
IPC: A01D41/12
Filed: 1991-03-01
Abstract: STRAW SPREADER FOR A COMBINE HARVESTER ABSTRACT OF THE DISCLOSURE A straw spreader for the rear straw discharge of a combine comprises a frame mounted on ground wheels together with a pair of hitch arms which extend forwardly from the frame on either side of the rear portion of the combine for attachment to the combine frame structure. The separate frame can thus move up and down relative to the rear of the combine and maintains a pair of spreader spinners on the frame at a predetermined height relative to the ground. Guide surfaces collect the material from the chopper at the rear of the combine and direct it onto the spinners for a spreading action. The low height of the spreading action reduces dust emission and enhances spreading consistency. An accumulator can be provided between the spreader and the discharge in the rear of the combine to allow the amount of straw spread to be varied relative to the amount collected at any particular point on the field.

Title: Method of treating materials at low temperatures
Inventor: HUME FRANK C
IPC: F25D31/00
Filed: 1991-04-26
Abstract: ABSTRACT OF THE DISCLOSURE    Materials such as tool steel, plastics and natural fibres are treated at low temperatures to enhance their performance.  An economical process provides for first cooling the material down to about -70°C for a predetermined time followed by an intense cooling step down to about -190°C for a short duration.  The materials are allowed to warm up in two stages pausing between stages at about -70°C.  The specific time/temperature program utilizes liquid carbon dioxide and liquid nitrogen and may be varied for the materials to be treated.

Title: Routing objects on action paths in a distributed computing system
Inventor: ARTSY YESHAYAHU
IPC: G06Q10/10
Filed: 1991-05-07
Abstract: ROUTING OBJECTS ON ACTION PATHS          IN A DISTRIBUTED COMPUTING SYSTEM                 ABSTRACT OF THE INVENTION      A system for routing an "object" (in the sense that object means an abstraction that encapsulates data in a known way, with a known list of operations or methods to access the data, and the object has a unique identity, is mobile, and possibly persistent).  The "object" is routed in a distributed computing system along an action path (itself an "object") which defines the logical path to be traversed by the object.  The action path consists of action stops naming or describing functionally principals (people or automated mechanisms) required to act upon the routed object in a prescribed order.  The object routing system propagates the object along this action path, and monitors and controls its progress until it completes the path.  The system includes mechanisms of dispatching the routed object between principals, finding the principals required to act on the routed object, notifying the principals in turn of their required action, and potentially relocating the routed object to the nodes of the principals.  Optionally, the object routing system may use mechanisms for nagging principals about pending actions (if no progress occurs within a specified period), reporting such lack of action or progress to other principals, supporting the sharing of an action path by multiple routed objects, and facilitating the routing of an object in parallel to multiple principals. This object routing system is constructed as a generic service layer above services for object management, migration, persistence and interobject communication.

Patent CA-2042941-A1 (CA)
IPC: F16H55/46
Filed: 1991-05-21
Abstract: A split power transmission element, such as a sprocket, mountable on a driven shaft.  A pair of substantially identical sprocket halves each include a pair of aligned, hollow, fastener sleeves extending diagonally through the plane of the sprocket.  A pair of fasteners within the sleeves join the sprocket halves to each other and clamp the sprocket onto the shaft.  The diagonal orientation of the fastener sleeves permits convenient disassembly of the sprocket from an upwardly located, axially displaced position.  The sprocket halves are substantially identical and can be economically molded using a single mold.  A keyway insert distributes driving forces throughout the sprocket hub and increases the maximum torque capacity of the sprocket.

Abstract: ABSTRACT OF THE DISCLOSURE      A removable closure cover for a drinking vessel such as a cup or mug has an outer cover for attachment to the mouth of the vessel, with an aperture adjacent the edge through which a user may drink.  An inner cover secured to the outer cover is selectively moveable into opening or closing relation with the aperture.  While useable with insulated plastic drinking cups, the closure cover also may be used with traditional mug or cup forms, to enable tranportation of a hot drink in sealed, in-sulated relation, thus extending the utility of the tradition-al,  non-disposable  mug,  in  an  ecology  promoting  fashion. Manipulation of the cover provides controlled ventilation of the container and permits modulation of the cooling time for a hot drink contained therein.

Abstract: A sonar buoy 40 has narrow-beam sonar heads 80, 82 driven by a stepper motor 84.  The heads produce sonar data for example accurately measuring the seabed.  The buoy is handled by a crane wire 41 held taut by a float above the buoy and attached to a clump weight 46 resting on the seabed (although shown in retracted condition).  A wire 50 runs from a winch 48 around pulleys 52 on the weight 46 and is connected to a lever 54 of a gimbal mechanism 56 which has two transducers 62, 70 giving measurements of the "X" position and the "Y" position of the buoy.  A footage mechanism 76 is driven by the wire 41 and has a transducer giving a measurement of the heave position.  A compass 88 and roll and pitch transducers at 86 give measurements of the heading position and the roll and pitch positions.  The sonar data is compensated for the position of the buoy using a computer.     (Fig 5)
