Abstract: ABSTRACT OF THE DISCLOSURE        A strap retainer includes a flexible plate adapted to be attached by sewing to a substrate, and a retaining mound integral with the plate and raised above the upper surface of the plate so as to define therebetween a pair of laterally aligned apertures for the passage therethrough of the strap.  A sewing groove extends in the upper surface of the plate along a peripheral edge of the plate for receiving a sewing thread.  A support ridge projects from the bottom surface of the plate and extends along the periphery of the plate, the ridge being disposed inwardly of and immediately adjacent to the sewing groove.  The strap retainer thus constructed is free from curling up around the periphery thereof and is capable of protecting the sewing thread against abrasive wear.

Title: Automatic packaging machines with wear resistant parts
Inventor: TISMA STEVEN

Granted: 1992-06-23
Abstract: Abstract of the Disclosure An automatic packaging machine transports an object over a path having a freedom for both horizontal and vertical movement.  Horizontal rails support a pair of guide blocks positioned to slide over the rails,  Each of the guide blocks has a pair of spaced parallel slots with a T-shaped cross-section confronting individually associated ones of the rails.  A replaceable wear resistant track is slidably captured within each of the T-shaped slots, to slide over an individually associated one of the rails.  A vertical support bar interconnects the second guide blocks.  An upper and a lower U-shaped block is attached to the vertical support bar at vertically spaced locations.  A keeper is secured over the open space of each of the U-shaped blocks.  A block of wear resistant material is positioned in a recess in each of four interior surfaces of the U-shaped block and keeper, a slidable vertical bar being captured and sliding within the embrace of the U-shaped blocks.  There is enough play within the sleeve member for the slidable vertical bar to swing out of a sleeve member having a keeper removed while the other keeper remains in place, to enable the wear blocks to be replaced.  The slidable vertical bar carrys the object over the path.

Granted: 1993-05-18
Abstract: Abstract of the Disclosure Digital Oil Level Sensor An oil level sensor includes a sensor body adapted to be mounted to the block or casing of an oil-containing reservoir.  A probe including a pair of electrodes forming a capacitor extends from the sensor body so that the capacitor will be at least partially immersed in the oil to detect the level thereof.  At least one of the electrodes is insulated so that the apparent capacitance of the capacitor is relatively insensitive to any change in the conductivity of the oil at high temperatures.  Circuitry is provided in response to the capacitance of the capacitor for signalling the level of the oil, which capacitance is a function of the oil level.  The sensor body is mounted to the block by external threads on the probe. The electrodes of the probe extend proximally past the threads to provide an increased capacitance for the sensor.  The electrodes of the probe are concentric and the inner electrode is supported at both ends to reduce fatigue.  Circuitry is also provided for automatically testing the proper operation of the sensor .

Abstract: METHOD OF IMPROVING THE AREAL SWEEP EFFICIENCY      OF A STEAM FLOOD OIL RECOVERY PROCESS                                ABSTRACT            A method for the recovery of oil from a subterranean, oil-containing formation by a cyclical steam flood-pressurization and production program.  During the first cycle, steam is injected into the formation and oil is recovered until there is steam breakthrough at the production well.  Thereafter, a pressurization cycle is initiated by throttling or shutting-in the production well while continuing injection of the steam until the bottomhole injection pressure is greater than the vertical pressure created by the overburden thereby causing the formation to fracture horizontally.  After the horizontal fracture is formed, the third cycle or production cycle is initiated in which oil is recovered from the formation from either the production well or the injection well or both until the amount of oil recovered is unfavorable. Also, during the production cycle, if oil is recovered only from the injection well or the production well, steam may be injected into the nonproducing well until the amount of oil recovered is unfavorable.  Thereafter, the steam flood, pressurization and production cycles may be repeated for a plurality of cycles until the production of oil is uneconomical.  Optimum results of fracturing is obtained during the pressurization cycle when the bottomhole injection pressure is greater than 0.9 psi per foot of the true vertical pressure created by the overburden.

Granted: 1992-06-23
Abstract: ABSTRACT The invention relates to a device for combining partial piles of book pages by laying one on another. The partial piles may be brought up alternately in an inclined position on a conveying chain. According to the invention, there is provided above the conveying chain a rotary rearranging apparatus. The rearranging apparatus carries a plurality of gripping systems each adapted to pick up one partial pile of book pages and, after rotation of the rearrangement apparatus through a 360 degree revolution, deposits the partial pile of book pages beside an identical succeeding partial pile. During the 360 degree revolution of the rearranging apparatus, each gripping system is rotated about an axis parallel to the rotational axis of the rearranging apparatus such that the gripper systems continuously remain in an upright orientation with the grippers always projecting downwards at the lowest point of the gripping system. Before combination of any given partial pile of book pages with another partial pile, every such given partial pile may be rotated by the respective gripper system through 180 degrees about an axis extending at 90 degrees to the normal of the plane of the partial pile, and for this purpose every gripping system of the rearrangement apparatus is mounted so as to be rotatable about a vertical axis and, in a part of its orbital path of motion during the 360 degree revolution of the rearranging apparatus, is rotated through 180 degrees about this vertical axis.
