Title: High speed automatic packaging machine with anti-centrifugal force transport means
Inventor: TISMA STEVAN
IPC: B65B39/14
Filed: 1991-11-12
Granted: 2001-09-25
Abstract: A high speed automatic packaging machine is constructed from standardized modules in order to reduce cost and standardize operational an maintenance procedures. The standardized modules include conveyor chains trained over sprocket wheels to form modules which may be ganged to maintain synchronization of operations.      Various types of mandrels may be attached to the conveyor chain in order to adapt the machine to load different types of products. The mandrels experience significant centrifugal forces as they go around the path defined by the sprocket wheels. To prevent the mandrels from slapping the conveyor chain when it is traveling at high speed, a leading end of the mandrel is pivotly connected to the chain while a trailing end of the mandrel is captured within a slot which allows the mandrel to go around the sprocket wheel without departing therefrom.

Title: Methods for making toothed belt construction
Inventor: THOMAS DANNY L
IPC: B29D29/08
Filed: 1990-07-20
Granted: 2000-04-18
Abstract: An improvement is provided in a method of making a toothed belt construction that has a toothed surface means and that comprises a belt sleeve from which individual endless belts are subsequently cut in a conventional manner, the belt sleeve having a preformed fabric means lining the toothed surface. The method includes the first step of forming the preformed fabric to have serially disposed tooth-shaped projections throughout its length so as to line the toothed surface thereof. The fabric is disposed onto an externally toothed cylindrical mould member used to form the belt sleeve.      The belt sleeve is formed on the mould member with material so that the fabric forms part of the belt sleeve with the material. The preforming fabric is formed from an endless tubular sleeve that has the tooth-shaped projections formed therein while the fabric means is still in the endless tubular sleeve form thereof. The endless tubular sleeve in its pre-formed condition is disposed on the mould member by axially sliding the sleeve in a telescoping manner onto the mould member before the step of forming the belt sleeve. The fabric is disposed in the endless tubular sleeve form thereof between a pair of cooperating and telescoped cylindrical mould members respectively having teeth that index with each other to form the tooth-shaped projections of the fabric. One of the mould members is formed by deforming a first sleeve of polymeric material under heat and pressure against a cylindrical mould device that has teeth thereon. The first sleeve is removed from the mould device and is inverted. A second sleeve of polymeric material is deformed under heat and pressure against the inverted first sleeve to form teeth in the second sleeve.   The sleeves are inverted while the second sleeve is against the first sleeve. The inverted sleeves are separated to comprise the cylindrical mould members to be utilized to form the fabric therebetween.

Title: Full-duplex video communication system
Inventor: TANENBAUM RICHARD
IPC: G06F15/177
Filed: 1990-12-13
Granted: 2002-03-12
Abstract: Each terminal (30, 60) in a full-duplex communication system comprises a computer-controlled display screen such as a CRT (62, 32), at least one input means such as a keyboard (64, 34), a mouse (36, 66) or a light pen (38, 68) and bidirectional communication means (40, 70) through which the terminals (30, 60) are interconnected. Each communication means comprises a receiver (78, 48) for receiving display information received at the terminal from the remote terminal(s) and a transmitter (46, 76) for transmitting information to the remote terminal(s) where it is displayed. In accordance with the invention, each terminal also comprises control (50, 180) which periodically reads its input means and communications means and uses the information contained therein to control the content of its display. Further, the control means at each terminal also provides to its transmitter instructions (figure 3) which are transmitted to the remote terminal to change the display at the remote terminal so that all the displays are the same. As a result of this arrangement, changes in the display that are made at the same time by the user at the local terminal and by the user at the remote terminal are entered on the display screens at both terminals at substantially the same time so far as is discernable by the users. As a result, not only can each user interact with the display but it is also possible for each user to interact with the other users through the display without having to wait for one user to complete his entry of information as in the prior art. As a result, truly interactive communication is possible through the display.

Title: Method and apparatus for non-atmospheric venting of evaporator over-pressure in a refrigeration system
Inventor: BARTLETT DAVID W
IPC: F25B49/00
Filed: 1993-02-16
Granted: 1996-06-04
Abstract: An over-pressure control apparatus for a refrigeration system provides for non-atmospheric venting of an evaporator during over-pressure conditions.  The control apparatus includes a sensor for indicating evaporator pressure, a storage vessel for receiving liquid refrigerant from the evaporator, and a controller responsive to the sensor.  The controller acts in response to the reading of the sensor to selectively open and close at least one control valve coupling the storage vessel to the evaporator and condenser of the refrigeration system. Liquid refrigerant is vented from the evaporator to the storage vessel in response to a detected over-pressure condition.            The over-pressure control method hereof acts to vent liquid refrigerant from the evaporator at a predetermined pressure above normal operating pressure, but below the pressure where emergency venting of refrigerant vapor from the evaporator to the atmosphere is required.  The liquid refrigerant vented from the evaporator can be returned from the storage vessel to the refrigeration system after the evaporator is restored to normal operating pressure.

Abstract: A thin-walled valve guide insert for lining and relining a valve guide of an internal combustion engine includes opposing ends each having a tapered insertion section thereon.  The tapered insertion section defines a reduced outer diameter to facilitate installing the insert into a valve guide bore have a nonchamfered opening, and further defines a reduced inner diameter so that the insert has a substantially continuous wall thickness throughout its length and thus maintains the structural integrity of the insert from end to end.  In the preferred embodiment, the valve guide insert is made of a phosphor bronze material of about .018 inch thickness or less, and includes a lengthwise slit therein.  The insert is sprung open longitudinally along the slit and must be radially compressed so that the insert defines a sufficiently small outer diameter so that it can be axially installed in a press-fit condition into the valve guide bore of the engine.  Both ends of the insert are formed with the tapered insertion section so that the insert can be positioned without regard to which end is directed toward the valve guide.  Also disclosed is a tool for inserting the insert into the guide valve, the tool including an outwardly tapered junction adapted to spread one of the tapered insertion sections of the insert into longitudinal alignment with the insert to reduce the tendency to crush same from end forces exerted on the insert while installing the insert into the valve guide.  Still further a process is disclosed for forming the guide valve insert with ends having tapered insertion sections thereon.
