Abstract: Wp-1584 - C & C (Canada) HOLLOW WALL FASTENER                    ABSTRACT           A hollow wall fastener using a specially shaped or conventional threaded bolt and a toggle anchor which is pointed and which has an open groove for receiving the bolt.  The end of the groove has a threaded portion which cooperates with a threaded portion of an aperture opposite the groove to permit the anchor to pivot with respect to the bolt to a position where the bolt is threadably engaged and locked in the threaded portions of the anchor, forming a "T" configuration behind the surface of the hollow wall.  Thereafter the bolt may be rotated, e.g. by turning a screw or fastener body, to draw the anchor tightly against the interior of the hollow wall.

Abstract: ABSTRACT OF THE DISCLOSURE         A toy vehicle assembly capable of controlled locomotion in response to variations in frictional resistance along a support surface and method is provided.  The support surface is a relatively low frictional surface such as a flexible sheet of polyethylene.  A subjectively determined higher frictional guide pattern can be placed on the surface such as by a wax marker.  The toy vehicle has a pair of driving front wheels and a power rear wheel.  The axis of rotation for each of the wheels are non-parallel to the other axes.  A coefficient of friction of the power rear wheel is greater than that of the front control wheels.  The driving power wheel can propel the vehicle while the front control wheels can respond to variations in the frictional resistance of the support surface to control the direction of the toy vehicle.  The frictional path can be subjectively varied and is preferably made from a water soluble material that can be removed from the support surface.

Abstract: ABSTRACT OF THE DISCLOSURE           A humidity control system, such as can be used with a piano to control the level of humidity within the interior of the piano, is comprised of a low water measuring/warning sub-system and a "blind" refill sub-system.      The low water measuring/warning sub-system comprises stainless steel probes extending below the water level in a humidifying unit when the unit is filled with water.  When the water in the humidifying unit is sufficiently high to cover the ends of the probes, a neon light is shorted, the absence of light emission from said neon light thereby indicating a sufficient water supply to be present in the humidifying unit.  Evaporation of the water to a level below the ends of the probes causes a circuit including the neon light to be completed, thereby causing the light to be lit and indicating that the water supply in the humidifying unit has been diminished by a predetermined amount and can be replenished by said predetermined amount without the need for visual observation of the humidifying unit.  The "blind" refill sub-system comprises a water refill conduit fixed in operative relation to the humidifying unit, the conduit having a water-receiving funnel attachable to the distal end thereof and disposed for convenient access such that the humidifying unit can be exactly refilled without the need for visually observing the unit to avoid overfilling.

Abstract: Abstract of the Disclosure Electrode material is laser machined from a piezoelectric device (10) to adjust its resonant frequency to nominal value.  At the same time the device (10) is electronically cleaned by overdriving the device at a high current level to prevent loosely adhering lasered particles, which cause the device to be electrically unstable, from accumulating on the device.  The simultaneous laser machining and electronic cleaning also eliminates erratic resonant frequency changes in the device (10) which occur if the electronic cleaning is performed after the laser machining.  As the nominal resonant frequency value is approached, the device (10) is overdriven at successively lower current levels and the laser machining is carried out at respective successively lower rates.

Abstract: - 37 -HIGH SPEED PRINTING SYSTEM ABSTRACT OF THE DISCLOSURE The present invention relates to a high speed printing system, in which the printing intensity of each type element, applied onto a record media, is varied in accordance with the size of the surface area of the type element. The system employs a double control mode, in each hammering operation, for carrying out the variation of the printing intensity. The double control mode is comprised of a first control mode and a second control mode, which follows immediately after the first control mode. In the first control mode, a maximum energizing current is supplied to a hammer means, comprised of a dc motor, for hammering a selected type element to produce a desired character on the record media, and; then, in the second control mode, an energizing current is applied to the hammer means. The latter energizing current has variable peak amplitude which is suitable for carrying out fine control of the printing intensity in accordance with the size of the surface area of each type element.

Abstract: GROUND FAULT PROTECTIVE SYSTEM REQUIRING REDUCED CURRENT-INTERRUPTING CAPABILITY     ABSTRACT OF THE DISCLOSURE        A ground fault interrupter type device for protecting an electrical load device such as a range which has conductors supplied from a power source including overcurrent interruption means for interrupting the power source when a predetermined current threshold is exceeded.          The electrical load device is subject to a first class of failure characterized by excessive current flow between at least one of the conductors and a ground reference point, with circuit current remaining at or below the predetermined current threshold; and to a second class of failure characterized by current through at least one of the conductors being above the predetermined current threshold.  Failures of the second class include ground fault failures.  In order to reduce the current interruption capability requirement for the ground fault interrupter device, there is included a means fro preventing conductor interruption thereby in the event a failure of the second class occurs. Accordingly, the current-interrupting capability is at least as high as the predetermined current threshold but less than the maximum current which may flow during a failure of the second class.          In the illustrated embodiments, the means for preventing conductor interruption in the event a failure of the second class occurs is a time delay which delays the activation of the ground fault interrupter for an interval sufficient to allow the overcurrent interruption means to interrupt the power source in the event a failure of the second class occurs.

Secured to the lower end of the arm is a peg supporting element, which may be arc shaped.  A latch secures the creel normally in a stowed position above the machine, in order to avoid blocking the aisle adjacent the machine.  With the creel in this stowed position, yarn from spools on the pegs of the creel is supplied to the machine.  When empty spools are to be replaced, the latch is released, to allow the creel to swing by gravity to a second position which is over the aisle adjacent the machine and which is sufficiently low to permit an operator easy access to the spools.

A start signal, channel selection signal, control data signal and end signal are sequentially generated to transmit control data to a selected receiver to control a desired output.  Each cycle is divided into at least two phase sections, the one being used for a busy signal and the other being used for a data signal.  The data transmission system includes a plurality of transmitters and a plurality of receivers coupled to the power line.  Each of the transmitters comprises a receiving circuit for receiving a busy signal from other transmitter, a transmitting circuit for transmitting a data signal, a key input switch for operation, a selecting switch for selecting a channel which receives the transmitted data signal, and a memory for storing the key input signal.  The transmitting circuit generates a data signal in response to the key input signal stored in the memory and to a non-busy signal.
