  • Patent number: 5774652
    Abstract: A restricted access computer system. The system comprises a general purpose computing platform and a control system comprising a control hardware device and a control software program. The control hardware device is connected to the computing platform and to an access-status device such as a coin hopper or the like. The control software program runs on the computing platform and, in a secure mode, replaces the graphical user interface portion of the operating system of the general purpose computing platform. The control hardware device and control software program interoperate to allow access to application software programs on the computing platform only when certain conditions are satisfied. The control hardware device resets the computing platform if the control software program fails to communicate therewith. The control hardware device also restricts operation of the user keyboard and display monitor to reduce the possibility of unauthorized use of the computer system.

  • Patent number: 5760495
    Abstract: A power supply for generating an uninterruptible AC power signal. The power supply utilizes leakage inductance in its transformer to eliminate the need for an output inductor. In standby mode, the AC power signal is generated from a battery by a switching circuit. Certain components of the switching circuit are also used to charge the battery when the power supply is operating in line mode.

  • Patent number: 5733674
    Abstract: A power supply system that allows a user to standardize on one or two battery types and use these supported types to power electronic devices designed to use other, non-supported battery types. A battery sleeve is provided to convert the form factor of one battery to that of another battery. The system may also include a battery pack assembly that allows batteries of a supported type to be used to power electronic devices designed to use a conventional, proprietary battery pack design. Such battery pack assemblies allow dedicated, single use battery chargers sold with a given electronic device to be used to charge consumer capped batteries that may be used in other electronic devices. A universal charger/power supply unit may be provided that can used to charge a variety of rechargeable batteries and provide power to a variety of electronic devices.

  • Patent number: 5727736
    Abstract: A fluid dispensing device having a housing assembly, a conduit assembly, and a shut-off valve assembly. The conduit assembly engages the housing assembly to form a first valve assembly that prevents fluid material from reaching a mixing location in a closed configuration and allows fluid material to reach the mixing location in an open configuration. The shut-off valve assembly comprises a valve housing and a valve member disposed within a valve chamber defined by the valve housing. When the conduit assembly is in the closed configuration, pressurized air within the valve chamber forces the valve member into a closed position against the valve housing to prevent pressurized air from reaching the mixing location. When the conduit assembly is in the open configuration, it displaces the valve member into an open position in which pressurized air can flow from the valve chamber, through the conduit assembly, and to the mixing location.

  • Patent number: 5719503
    Abstract: Pulse propagation analysis to ascertain whether an anomaly such as surface corrosion exists on a section of conductive member such as pipe. Anomalies such as surface corrosion result in localized velocity changes of pulses, due to inherent nonlinearities, propagating along a conductive member. These localized velocity changes exhibit themselves in changes in waveform, rise and fall time, amplitude, and time delay of a pulse with respect to a fixed time reference. To allow such anomalies to be located, two pulses are generated such that they intersect at intersecting locations along the conductive member. The resulting modified pulses are analyzed for perturbations indicative of localized velocity changes.

  • Patent number: 5715975
    Abstract: An apparatus for applying spray texture to a wall or the like. The apparatus comprises an aerosol can containing pressurized spray texture material. The spray texture material is released from the can by a valve and passes through a nozzle passageway, out of a discharge opening, and on to a surface to be textured. The apparatus further comprises an outlet member that can be placed over the discharge opening to vary the effective cross-sectional area thereof. This outlet member can be in the form of a straw or tube that is inserted into the nozzle passageway or a disc or other member having a plurality of outlet orifices formed therein. The outlet member having a plurality of outlet orifices can be attached directly to an actuator member in which the dispensing passageway is formed.

  • Patent number: 5715651
    Abstract: A process for fitting stretchable labeling sleeves on bottles or the like, according to which at least one pair of stretchers is introduced into the sleeve, the stretchers are moved apart in order to stretch the sleeve, and the bottle and the stretchers are displaced relative to one another in order to postion the stretched sleeve on the bottle, which process is characterised in that, during relative displacement of the attached sleeve and the bottle, suction is effected in the area of contact between the sleeve and the stretchers in order to maintain the sleeve on the stretchers while it is being fitted on the bottle.

  • Patent number: 5691897
    Abstract: A system for motion control in which an application is developed that is independent from the actual motion control hardware used to implement the system. The system comprises a software system that employs an application programming interface comprising component functions and a service provider interface comprising driver functions. A system programmer writes an application that calls the component functions. Code associated with the component functions relates these functions to the driver functions. A hardware designer writes driver code that implements the driver functions on a given motion control hardware product. The driver functions are separated into core and extended driver functions. All software drivers implement the core driver functions, while the software drivers need not contain code for implementing the extended driver functions.

  • Patent number: 5653556
    Abstract: An apparatus for attaching a caisson to a device for inserting and/or extracting the caisson. The apparatus comprises three beams. A first beam is relatively long and is normally connected to a vibratory device such that its longitudinal axis is orthogonal to the lengthwise axis of the vibratory device. The second and third beams are relatively short and are connected to the vibratory device such their longitudinal axes are parallel to the lengthwise axis of the vibratory device. Four clamps are mounted on the beams to fix the beams onto the caisson. A flange on the first beam is widened at least a middle portion thereof to stiffen the beam and allow the beam to be securely connected to the vibratory device. The first beam may also be used with its longitudinal axis parallel to the lengthwise axis of the vibratory device.

  • Patent number: 5647455
    Abstract: A foldable sawhorse comprising first and second leg structures each having a hinge member integrally formed therewith. One of these hinge members is an outer hinge member having a passageway extending therethrough. The other hinge member is an inner hinge member adapted to extend through the passageway in a way that allows the leg structures to rotate relative to each other about a pivot axis. An engaging member is attached to the outer hinge member such that, when the sawhorse is in use, the engaging member is appropriate for engaging a workpiece or other surface to be supported. The hinge members as described above engage each other in a manner that creates a very strong and durable pivot or hinge mechanism. Locking assemblies are employed to fix the sawhorse in an open configuration and allow it to be closed into a closed configuration for storage.
