Title: Sag compensating roll for roll presses
Inventor: SCHIEL CHRISTIAN
IPC: B30B3/00
Filed: 1990-07-19
Abstract: SAG COMPENSATING ROLL FOR ROLL PRESSES            ABSTRACT OF THE DISCLOSURE          A sag compensating roll having a stationary yoke for taking up bending forces, a hollow roll shell surrounding the yoke and hydrostatic support elements between the yoke and the shell.  Each support element having a pressure shoe facing the inner surface of the shell defining a slide surface at the shell.  Relief pockets recessed into the slide surface.  A pressure space defined between a first piston on the yoke and the pressure shoe, and the shoe is radially movable with respect to the first piston.  A pressure fluid line communicates with the pressure space and, by capillaries from the pressure space, communicates with the relief pockets.  The pressure space and the relief pockets are dimensioned so that the active surface of the relief pockets is larger than the active surface of the pressure space acting on the support element.  A further fluid supply line delivers temperature equalization fluid to an additional pocket located at the circumferentially downstream trailing side of the pressure shoe, at the inner surface of the roll shell. The further fluid is picked up by the inner surface of the roll shell after the shell has moved past the relief pockets.  Pressure and/or quantity control between a common source of pressure fluid and each of the pressure fluid line and the additional fluid line may be provided.

Title: Transportation system
Inventor: HAMY NORBERT
IPC: B66B9/10
Filed: 1990-09-13
Abstract: An urban transportation system comprises a continuous stationary track having a pair of opposed rigid bearing surfaces, and a plurality of discrete cantilevered load-carrying vehicle units movable beside said track. Each vehicle is coupled to the track by means of a bogie having a linear arrangement of bogie wheels running between the bearing surfaces. The bogie wheels are mounted on mutually articulated frames and have a diameter slightly less than the separation of the opposed bearing surfaces to allow limited pivoting movement of the frames within the track. The adjacent articulated frames are forcibly urged to pivot in opposite directions within the track between the bearing surfaces such that bogie wheels carried thereby forcibly and alternately engage the respective opposed bearing surfaces at at least three points to ensure a pre-loaded positive coupling between the bogie and the track.

Title: Instrumentation clamp
Inventor: GRANTZ ALAN L
IPC: A61B17/22
Filed: 1990-12-21
Abstract: INSTRUMENTATION CLAMP                      Alan L. Grantz David A. Gollnick ABSTRACT OF THE DISCLOSURE      A clamp for clamping instrumentation uses a resilient tube and a compression housing operatively associated with the tube for providing a compressive force on the tube.  The compressive force is distributed generally equally over the length of the tube so that instrumentation disposed through the tube is substantially secured within the housing with minimal deformation.  The clamp is especially adaptable to fragile instrumentation, such as optical fibers, which typically are clamped for manipulation.  In one embodiment, the clamp is permanently attached to one instrument, while clamping another instrument for simultaneous manipulation.  In another embodiment, the instrumentation clamp can couple to one instrument temporarily, while clamping another instrument. This embodiment is designed to be self contained and readily adaptable for multiple uses.

Title: Key telephone system with enhanced connectivity
Inventor: WIEBE CHARLES R
IPC: H04M9/00
Filed: 1991-01-31
Abstract: A key telephone system which is operably responsive to digitally encoded service orders and instructions stored in a ROM of a switching facility in a local ISDN telephone exchange achieves enhanced connectivity by using a dedicated line that provides a digital signaling and supervision communications path which is exclusively an ISDN basic rate OB+D teleservice channel.  A key switch unit of the system is connected to the exchange by POTS lines  to provide conventional voice analog services to a plurality of its subscriber stations.   Interfacing the key switch unit with the teleservice channel, a personal computer translates data downloaded from the switching facility into instructions recognized by the unit and enables individual subscriber stations with enhanced service connectivity features while displaying such features on a display unit of each station.

Title: Tamper-evident container cap
Inventor: REPP RICHARD E
IPC: B65D55/06
Filed: 1991-07-23
Abstract: ABSTRACT OF THE DISCLOSURE      The cap is of a tamper-evident type having a flat top disk and a peripheral depending skirt.  A stacking, non-nesting rabbet is formed at the corner of intersection of the disk and skirt.  The skirt slants downward-inward from the top and the area of a horizontal tear line and then slants downward-outward to its bottom edge. A tear strip is used to pull off the lower half of the skirt.  Internal locking beads engage the external beads of the container neck.  The wide bottom edge of the skirt rests on the rabbet of an underlying cap for stacking and to prevent nesting during transportation.  The slanted upper part of the skirt is a means for removing the cap from the neck after the lower skirt has been torn off.

Inventor: RABITSCH BENJAMIN
IPC: B05B7/04
Filed: 1990-04-18
Abstract: A spray nozzle to discharge liquid material in a pattern which has the same quantity of liquid material in each increment of the pattern. The nozzle may be used in various orientations in which a supply of pressurized liquid is available, with the liquid being discharged generally in a lateral direction in relation to the path of movement of the nozzle thereby rendering the nozzle quite effective for use in discharging liquid fertilizer, growth retardant, insect sprays, orchard spray material and the like in an effective manner. In one embodiment of the invention, a nozzle is provided with a discharge passageway, a downwardly-opening, inverted U-shaped extension of the passageway, and a curved blade diffuser in the inverted U-shaped extension of the passageway to break up the liquid flow into droplets and to cause the droplets to be discharged in a lateral pattern so that a substantially equal quantity of liquid material is discharged in each increment of the path being traversed by the nozzle. In another embodiment of the invention, an additive injector is incorporated into the nozzle which enables a controlled quantity of liquid material to be injected into the main flow of liquid being discharged, with the diffuser effectively serving as a mixer for the additive and the liquid being discharged from the nozzle.

Title: Retortable container
Inventor: PARKINSON KEITH
IPC: B29C51/42
Filed: 1991-12-12
Abstract: A retortable container has a wall of at least two co-formed laminas. This wall is highly impermeable to fluids selected from the group consisting of oxygen and aromatic vapors. The wall includes a first load-carrying lamina of a first plastic material. This load-carrying lamina has been formed without mechanical hysteresis in the melt phase by a thermal pressure forming apparatus to cause strengthening with orientation of the load-carrying lamina in at least one axis but without memory of its pre-melt phase shape. The wall also includes a second sealing lamina of a second plastic material.      This second sealing lamina is coextensive with the first load-carrying lamina. Consequently, the container formed by the apparatus is retortable, i.e. it can withstand temperatures and pressures of a retort chamber without undergoing signifi-cant and permanent distortion.
