Abstract: ABSTRACT OF THE DISCLOSURE          A system for sensing the position in space of the outer end of an articulated fluid loading arm while it is connected to a marine tanker or other transport vessel, and for sounding an alarm if the arm's operating envelope is exceeded.  The sensing system includes means for deter-mining various angles representative of the orientation of the booms or limbs of the arm, and a microprocessor for using these angles to compute the spatial position of the arm's outboard end.  The boundaries between the safe and unsafe areas of operation of the arm are stored in a digital memory and compared with the actual position of the arm.  The boundaries which define the safe areas can be any desired shape, and the shape can be readily changed by storing a new set of boundary values in the digital memory.          If desired, the location of the boundaries can be made to depend upon the velocity of the arm as it is being maneuvered.  When the outboard end of the arm moves into an unsafe area an alarm sounds, and the system is shut down if the arm moves a predetermined distance farther into the unsafe area.     -1a-

Title: Pre-programmable metering apparatus for a fluid  infusion system
Inventor: KNIGGE VINCENT L
IPC: A61M1/02
Filed: 1978-11-15
Granted: 1982-09-28
Abstract: Abstract of the Disclosure A system for infusing fluids into the human body includes a peristaltic-type metering apparatus which con-trols the flow of fluid through a disposable administra-tion set.  The metering apparatus includes a control system which allows the volume and rate of flow of the fluid to be infused to be accurately preset by the operator.  The control system provides an alarm function in the event of malfunction of the pump or occlusion of the tubing of the administration set, and a minimum pumping rate for maintaining fluid flow through the system after the desired volume of fluid has been infused.  Novel power supply circuitry within the control system renders the system immune to power line transients, and a novel bubble detector circuit provides for more reliable detection of air bubbles in the tubing.  A mechanical linkage between the pressure plate and downline flow restriction plunger of the metering apparatus provides for convenient loading of the administration set and for automatic closure of the plunger prior to use.

Abstract: ABSTRACT OF THE DISCLOSURE          A method and apparatus for dehacking and stacking brick or the like are disclosed for automatically removing arrays of brick from a back and for producing stacks of arrays suitable for packaging.  A gripper transfer grips full arrays of brick resting on the kiln car and deposits such arrays on one of two compacting tables.  While resting on the tables, the arrays are compacted to ensure lengthwise and lateral abutting alignment of the brick in the arrays.  The brick are subsequently transferred after compacting directly to a stacking elevator on which the stack is formed.  One compacting table is utilized to produce void rows and operates to withdraw compacted arrays from the stacking location so that brick can be removed to produce the required voids.  The array with void rows is then returned to the stacking station for transfer to the stacking elevator at appropriate times in the machine cycle.  The arrays consist of upper and lower courses and the void rows are formed only in the upper courses so that a full lower course can be gripped to support the void row course during transfer from the compacting table to the stack.

Abstract: Abstract of the Specification A dual spool side by side retractor structure on a common frame wherein both spools are acted upon by a common lock pawl element, the lock pawl element engaging the ratchet teeth of one of the two spools and then being positively and guidably driven by the first spool to powered engagement with the other of said two spools and the guiding occurring as a consequence of cam surfaces directing the pawl-to-ratchet engagement. The pawl lock element is activated by a sensor element such as a pendulum structure. The pawl lock element is located between and beneath the two spools and upon tilting, the lock pawl element pivots toward guided interference with one set of ratchet teeth whereupon the moving spool drives the pawl element up a cam ramp to lockably engage the second spool. The pawl element is first dis-placed by an actuating sensor element and then the pawl element is displaced and driven laterally by the first spool in a direction transverse to first displacement and up a ramp into contact with the retractor teeth of the second spool. The withdrawal and retraction directions of both spools are in an opposite sense to each other and the retractor spools are locked against any further withdrawal action when engaged by the pawl element. A spring in association with the cam-ramp restores the pawl element as retraction move-ment frees the pawl element.

The hub is rotatably journalled on the propeller shaft and contains transmission means between the shaft and the blades. The transmission means can be coupled between positions for forward, reverse and neutral. The invention uses the torque of the motor and the reaction moment of the water against the blades to achieve a relative rotation between the shaft and the hub, whereby the transmission means turn the blades to one of two stops, which define the positions for forward or reverse.

Abstract: METAL-INSULATOR-SEMICONDUCTOR      DEVICE MANUFACTURE                           ABSTRACT     A method of making a metal-oxide-semiconductor device is disclosed.  A thin silicon dioxide insulating layer is formed on the surface of a planar silicon wafer.  A first layer of intrinsic polycrystalline silicon is deposited over the dioxide layer, and a second layer of doped polycrystalline silicon is deposited over the intrinsic layer, thereby forming the gate.  Subsequent hot processing steps result in diffusion of a portion of the dopant from the doped polycrystalline layer into and throughout the in-trinsic layer so as to dope the latter.  A metal contact layer is then deposited onto the gate and in superimposed vertical alignment with respect to the thin silicon dioxide insulating layer.  The intrinsic nature of the first polycrystalline layer reduces grain growth and void formation in the polycrystal-line silicon and thereby prevents the silicon dioxide from being attacked by hydrofluoric acid seeping through voids in the polycrystalline layer during subsequent processing.  The yield for the manufacture of devices having thin oxide gates is substantially improved.

Abstract: HYDRAULIC RUNNING TOOL    FOR LINER HANGERS            Abstract of the Disclosure The present invention discloses an apparatus for running and setting a liner hanger in a well bore casing.  The usual liner hanger comprises two movable tubular members and a gripping means which is activated by relative movement of said members.  The running and setting tool of this invention is connected to each of the tubular members of the hanger by selectively releasable means and includes a pressure respon-sive piston and cylinder assembly which transmits relative movement to the tubular members and thereby sets the gripping means.  Coacting means on the running and setting tool and on the liner hanger prevents premature setting of the gripping means prior to piston and cylinder movement.  After setting the hanger, the tool and its operating parts including the piston and cylinder assembly are removed from the well.

Abstract: 20.2.1980                  1                     PHN 9493 ABSTRACT:     A stepping motor having a first and a coaxially disposed second annular stator section, which stator sections are axially spaced by a coaxially disposed permanent-magnetic ring. Each stator section terminates on the inner side in two coaxially disposed annular systems of teeth. The systems of teeth of each stator section have been mutually shifted nominally by 1/2 tooth pitch relative to the rotor toothing and the systems of teeth situated on the outer side relative to the permanent-magnetic ring as well as the systems of teeth situated on the inner side relative to the permanent-magnetic ring exhibit a mutual shift relative to the rotor toothing of nominal 1/4 tooth pitch. In this stepping motor stepping-angle errors can greatly be eliminated for a specific energisation by selecting the teeth geometries in such a way that the amplitude of the permeances of the air gap between the inner systems of stator teeth and the cooperating rotor toothing as a function of the rotor position is smaller than the ampli-tude of the permeance of the air gap between the outer systems of stator teeth and the cooperating rotor toothing as a function of the rotor position.
