Title: Method and device for the saving of electrical energy for the drive of an hydraulic lift
Inventor: NAGEL HEINZ-DIETER
IPC: B66B1/26
Filed: 1993-02-05
Abstract: With this method and this device for the saving of electrical energy for the drive of an hydraulic lift, it is possible to drive the lift cage in the upward direction with practically constant power for any loading. The maximum nominal speed in upward direction is chosen for a loading which according to experience occurs most frequently. The required size of the drive is designed in accordance with this choice. The hoist speed is reduced correspondingly for higher loads and increased correspondingly for lower loads. The variable hoist speed is achieved either through an adjustable pump (8) of variable displacement volume and controlled by a pressure-regulating valve (14) or through a positive-displacement pump (28) of constant displacement volume, which pump is driven by a frequency-regulated electrical motor (31) with stepless adaptation of the rotational speed of the electrical motor (31) in dependence on the effectively present loading.

Title: Ground proximity warning instrument using flight path modulation of glide slope alerting function
Inventor: BATEMAN CHARLES D
IPC: G08G5/00
Filed: 1992-09-16
Abstract: A ground proximity warning system monitors the flight path angle (78) or barometric or inertially derived descent rate (74) of the aircraft and modulates the glide slope alerting function (80) in accordance with flight path angle (78) or descent rate (74) when the aircraft is not descending rapidly even though it is below the glide slope in order to reduce nuisance warnings without compromising system sensitivity. Alternatively, the repetition rate of the alert may be varied as a function of the flight path angle (78) or descent rate (74) to provide less frequent alerts when the aircraft is not descending rapidly.

Title: Method for metallurgical enhancement of a failed bolt hole
Inventor: REYNOLDS SAMUEL D JR
IPC: B23P6/00
Filed: 1993-08-20
Abstract: A method for metallurgical enhancement of a failed bolt hole, or stud attachment, providing for replacement of service induced failed material from the female threaded area of the bolt hole. A method in accordance with the present invention is particularly suited for power plant equipment, such as a steam turbine. Failed material from the female threaded area is removed and filler metal is arc welded to the exposed base metal of the hole using a mechanized gas tungsten arc weld device employing a continuous spiral weld bead.      Proper selection of the filler metal, considering the base metal to which it is applied and, moreover, the type of failure which the base metal o! the hole has been experiencing, provides for improved structural integrity of the mechanical joint and increased service life of the associated steam turbine apparatus. Weld tempering of the filler metal reduces undesirable weakening of the weld metal in the heat affected zone, thus providing further metallurgical enhancement of the failed bolt hole.

Abstract: A head-mounted image display apparatus includes optical visual units mounted on a laterally disposed shaft and adjustable so as to be movable toward and away from each other for establishing a correct eye spacing for a user. LCD display panels are mounted within the optical visual units so as to be vertically movable while ocular lenses onto which images displayed by the LCDs are projected via an obliquely arranged mirror are positionally fixed relative the eyes of the user such that focus adjustment will not cause image dropout and so that focus and eye spacing may be established independently of each other. Sliders provided for effecting focus and eye spacing adjustment are mounted such that frictional force is applied thereto for providing smooth but sure movement of the sliders so that a set position of the sliders may be reliably maintained.      The sliders may be mounted via self a lubricating mounting to improve adjustment smoothness and slide characteristics.

Title: Bi-Planar Cable Cross Reeving System
Inventor: BAUMANN JAMES A
IPC: B66C19/00
Filed: 1993-10-13
Abstract: A crane and lift apparatus for controlling the lifting and lowering of large cargo containers.  A trolley assembly includes a hoist drum from which is suspended a system of cable or rope reevings connected to material securing assembly.  The apparatus is effective to unload containers stacked one above another from one location to an alternate location,  The system of cable reevings permits the raising and lowering of containers in planes defined by X, Y, and Z axes.  The cables are deployed from the hoist drum on the trolley assembly to sheaves disposed at the four corners of the material securing assembly and then returned to anchor assemblies secured to an undercarriage of the trolley assembly.  The sheaves are selectively angled and located in headblock assemblies positioned on the material securing assembly.  A system of brakes controls movement of the cables through the sheaves.  By selectively combining the angling of the sheaves with selective application of the sheave brakes, it is possible to resolve moment forces acting at each corner of a container so as to abosrb the constantly changing inertial. movements that occur when the container is raised, lowered or moved horizontally.  As a result, the apparatus is effective to dampen or retard the container from swaying, rolling, or pitching, from pendulous movement; and can thereby control the deployment of the container within precise vertical, horizontal, or skewed planes of orientation.
