Abstract: DEPLETION MODE FIELD EFFECT TRANSISTOR              MEMORY SYSTEM                 ABSTRACT OF THE INVENTION        The present invention relates to an integrated memory system comprising an array of depletion mode field effect transistors operated in a common control electrode mode to provide an array with the density of metal oxide semiconductor field effect transistor arrays and  the speed of bipolar transistor arrays.  Each transistor of the array has a gate or control electrode surrounding a channel region of the device which gate is held at a reference potential with respect to the source and drain regions which are selectively biased.        The invention can be utilized in both a random access memory and a read only memory mode.  The read only mode is somewhat of a simpler structure capable of a higher density than that of the random access. In both cases a low capacity, high density, high speed memory which is self limiting as to current and which uses a lower power requirement than comparable Bipolar memories is realized.        The field effect transistors of the invention are readily formed using existing processes that will permit bipolar devices to be made on the same chip.

Abstract: ABSTRACT OF THE DISCLOSURE             Disclosed subject matter includes flexible motor mounting members particularly adapted for vibration induced flexing movement combined with oscillatory movement about a pivot axis at a point of attachment on a blower housing or other support.  Short but strong mounting members are provided that have low torsional mode vibration transmissibilities.  Leaf spring mounting arms have low torsional spring constants and yet have sufficient strength to withstand shipping and handling loads for motor/blower assemblies and to permit all angle motor mounting.  The mounting member spring constants for axial, radial and tilting vibration modes are selected in specific forms so that the characteristic vibration transmissibility ratios for these modes are each close to unity.  However, the characteristic torsional mode vibration transmissibility is substantially less than unity.  In particularly preferred embodiments of the invention, sheet steel having a martensitic grain structure is utilized to form the mounting members.  Sends in this material have a radius of at least seven times the thickness of the material.  One method includes forming lugs or mounting members from the selected material and then trapping one end of these members between oppositely facing surfaces of fastening members.  In some forms, the motor shell constitutes one fastening member and a holding plate is another fastening member and, it is preferred to capture a motor pad portion of the lug against the motor shell and projection weld the projections from the plate to the motor shell.  This method by conventional welding processes.  This also provides a very strong fastening scheme that meets the rigors of shipping and handling as well as the rigors caused by prolonged vibration.        The free end of the lug is specifically configured to prevent Abstract - continued: deformation and tearing, and the lugs are extremely easy to mount to a blower housing simply by deflecting the mounting arms (when necessary) with finger pressure so as to align holes in the mounting arms with previously provided holes in the blower housing.  In another form, the motor end of mounting lugs are trapped between two pieces of steel that are welded together to form a mounting block having a strap accommodating slot therein.  The assembled blocks and members are then strapped to a motor shell.  In one particular procedure, I sandwich the motor end of a mounting lug between a motor shell and a reinforcing member at a welding station and weld projections from the reinforcing member to the shell.  Thereafter, a rotatable assembly is supported in the stator.  After the above-mentioned welding step, but prior to shipping the final motor assembly, it is preferable that at least the motor shell be treated (e.g., by painting) for appearance and corrosion or rust prevention purposes.

Abstract: COOKING DEVICE AND METHOD                  Abstract of the Disclosure The disclosed cooking device has a cooking cavity with an access opening and a door for closing same, and has a rack in the cavity to support the food to be cooked. The device has electric heating elements in the cavity, and control means that energize the heating elements approximately 10% to 45% of potential high level heat outputs thereof.  The total power input of the low level energized heating elements is in the range of 15% to 30% maximum and thus provides heating of air in the cavity only to within the range of 220° to 300°F maximum, without food load, and at a low rate so that the cavity air temperature generally will only exceed the temperature of the food by 20° to 50°F approximately during a sustained cooking cycle.  This low temperature method of cooking does not require personal tending to the food and minimizes the chances of burning the food.  Also different foods held in separate containers can be cooked simultaneously with this method for the same duration cook cycle while yet maintaining the individual taste characteristics of each food.  The cook cycle is slow and requires generally a minimum duration of approximately 5 or 6 hours and tolerates a maximum duration of approximately 12 to 20 hours.         The same or different heating elements can be energized at the high level outputs for providing conventional broiling or baking food cooking cycles.

Abstract: ABSTRACT OF THE DISCLOSURE      This invention relates to a trench shoring assembly which includes a pair of spaced-apart side walls for vertical disposition within a trench.  Spreader pipes and spreader collars interconnect the side walls and allow limited pivotal movement between the side walls.  Each side wall includes outer and inner metal plates connected to a horizontally extending hollow top beam which extends longitudinally along the top of the side wall, two intermediate beams parallel the hollow metal beam and a bottom beam.  A hardwood insert is disposed within the top beam to pre-vent the collapse of the hollow metal beam.  A number of hollow beams extend perpendicularly to the horizontal beams.  The members extend perpendicularly to the horizontal beams.  The side walls of the assembly have a tapered bottom portion which defines a triangularly shaped pointed lower extremity extending between the ends of the bottom portion.  A metallic bar is dis-posed at the pointed lower extremity and extends between the ends of the bottom portion and protects the bottom of the side wall against abrasion.  A U-shaped member is welded to the main frame, and, in turn, a spreader collar is welded to the U-shaped member so that a force applied to the spreader collar is transferred directly to the main frame.  Each spreader pipe spaces the side walls apart between two spreader collars to which the spreader pipe is attached by spreader pins.  Lifting rings are slidably attached to the spreader pins.  Lifting rings are slidably plurality of flanges extend from spreader pipe and are connec-ted by locking pins to mating flanges which extend from another spreader pipe of another vertically stacked trench shoring assembly.

Abstract: ABSTRACT OF THE DISCLOSURE            An ice removal system to protect a drill string in an ice covered waterway from possible damage due to ice movement.          The drill string extends down into the waterway from a vessel which has an ice melting system for melting ice coming into direct contact with it.  If the ice is thicker than the draft of the vessel, the unmelted portion of the ice passing under the vessel is deflected downward by ice breaking ridges surrounding the drill string.  The downward deflection causes the ice to fail in tension thereby breaking it up into a plurality of ice blocks.  The ice blocks float up into a moon pool surrounding the drill string, and are then flushed out of the moon pool through a channel and into the surrounding waterway.  A cylindrical protective plate surrounding the drill string prevents the ice blocks from coming into direct contact with the drill string and thereby possibly damaging it.

Abstract of the Disclosure Intravenous Fluid Pumping System having a controller and a pump controlled by the controller.          The controller has a sealed chamber with a flexible mem-brane covering a portion thereof.  An incompressible fluid is disposed in the chamber.  A piston member is movable in the chamber causing extension and retraction of the membrane as the piston is moved in and out relative to the chamber.  A motor is provided for reciprocating the piston.  The pump has a pump body with a pumping chamber therein with one portion of the pump body being covered by a flexible membrane in contact with flexible membrane carried by the sealed chamber of the controller.  The pump has an inlet adapter connected to the source of fluid.  The pump also has an outlet adapted connected to the patient.  Inlet and outlet valves are provided in the pump body whereby when the controller is operated to flex the membrane of the sealed chamber of the controller, the diaphragm of the pump is operated to cause movement of the valve members to cause fluid to pass from the source through the pump and to the patient under the control of the pump.  The controller is also provided with an alarm system whereby positive and negative pressure conditions in the pumping chamber can be sensed.         In the method a piston-like member is used to positively cause displacement of a liquid within a sealed chamber to cause movement of a flexible membrane forming a portion of the sealed chamber.  The movement of the flexible membrane causes simultaneous movement of another flexible membrane in intimate contact with the first-named flexible membrane.  The movement of the second flexible membrane is used to create a pumping action in a pump having a pumping chamber in which the last-named flexible membrane forms a part of the pumping chamber.
