Abstract: A process is disclosed for die-casting aluminum alloy A365.2, or like alloys having high aluminum and low iron content, which have hitherto not been formed into parts in die-casting processes because of undesirable soldering of the cast part to the steel die. In the disclosed process the molten aluminum alloy containing a maximum of 0.12 percent iron and at least 90 percent aluminum is injected under pressure into a die through a gate at an injection rate which is approximately 55 to 93 cubic inch per second. When the rate of injection of the aluminum alloy into the die is in this range, there is no sticking or soldering of the die-cast part to the steel walls of the die.

Abstract: A standard T-1 span is connected to a digital central office or remote terminal. Telephone equipment for such a T-1 span defines a superframe format with each frame of the twelve frames of a superframe having twenty-four eight-bit position time slots. Telephone system signalling requires T-1 signalling bits be located in the least significant bit position of each time slot in every sixth frame. In the disclosed system, simultaneous digitized voice and data share a single time slot for transmission along with the T-1 signalling bits in that time slot. In order to achieve the additional capability, the disclosed system employs least and next-to-least digitized voice bit swapping and a data bit occupying the space of the swapped least significant digitized voice bit, which bit is deleted.

Abstract: A tire carrier adapted with a bumper-mounted hinge plate housing a pivot rod having the lower portion of a generally inverted Ushaped tire mounting frame pivotably attached at the pivot rod is disclosed herein. A lower bracket extends vertically below the pivot rod and includes a pivotable connection point for rotatably housing a lower end of a gas cylinder. The upper end of the gas cylinder is rotatably mounted in an upper bracket which extends horizontally and toward the rear from a forwardly inclined top rail of the tire mounting frame. When in a normal upright position on a vehicle the gas cylinder is positioned vertically in a vertical plane located at the outer edge of a rear bumper of the vehicle. A spare tire to be carried is mounted on pivotably lug bolts which are rotatable about the upper portion of the tire mounting frame. A tire changing tool locks the pivot point of the hinge into an open horizontal position so that the carried spare can be removed from the tire mounting frame.

Abstract: An ultrasonic generating system for coupling vibrating energy into a load, such as living tissue, has been described which employs a piezoelectric crystal having excitation electrodes on opposite faces thereof. A feedback electrode is disposed on one face of the crystal adjacent to and insulated from one of the excitation electrodes to provide a feedback signal between the feedback electrode and the other excitation electrode. A power supply is provided for applying excitation energy to the excitation electrodes. The feedback signal is utilized to slave the frequency of the power supply voltage to the resonant frequency of the crystal and to disable the power supply when the impedance of the load applied to the crystal rises above a predetermined level.

A front guide bar is carried by the body member and extends outwardly from the front wall a distance sufficient to accommodate a fingerprint card so that the card can be inserted between the guide bar and the front wall and then bent back against the support surface to expose a desired row of fingerprint receiving spaces. The guide bar includes inwardly extending studs which are biased against the front wall to hold the card while it is being bent. A releasable adhesive is secured to the support surface to releasably hold a card thereagainst.

Abstract: A self closing lockable hinge system including a pin member and a sleeve member rotatable about the pin member. The pin member and the sleeve member have associated therewith mutually engageable surfaces such that upon rotation of one member relative to the other the sleeve member is movable from a lower closed position to an upper open position relative to the pin member. This movement is caused by engagement of the mutually engageable surfaces. There is also provided lock to retain the sleeve member in the lower closed position whereby in the closed position relative rotation between the pin member and the sleeve member is prevented. The lock comprises register means movable between a first aligned position whereby the movement of the sleeve member is permitted and a second misaligned position wherein the movement of the sleeve member is prevented.

Abstract: A clamp for regulating the flow of parenteral solutions is disclosed which includes a clamp body having a channel for accommodating a length of administration set tubing so that a portion of the tubing is compressed to a closed position while at least one side of the tubing is left uncompressed to provide a passageway for the solution. A cam member or platen is moveably mounted on the clamp body for applying an adjustable compressive force against the uncompressed side of the tubing to vary the area of the passageway and the rate of flow of the solution.

Abstract: A series of independent parallel pairs of light emitting and detecting diodes for a linear pixel array, which is laterally positioned over an edge-like discontinuity in a workpiece to be scanned, is disclosed. These independent pairs of light emitters and detectors sense along intersecting pairs of separate optical axes. A discontinuity, such as an edge in the sensed workpiece, reflects a detectable difference in the amount of light from that discontinuity in comparison to the amount of light that is reflected on either side of the discontinuity. A sequentially sychronized clamping and sampling circuit detects that difference as an electrical signal which is recovered by circuitry that exhibits an improved signal-to-noise capability for the system.

Abstract: A solar generator in the shape of a dome segment is disclosed. The generator utilizes an inner dome-shaped support structure nested inside a slightly larger output dome-shaped space frame. The space frame is adapted for rotation at a fixed angular velocity about the inner support dome. The space frame carries a plurality of prewired identical solar cell panels mounted on flat support planes, which are positioned at three preferred angles relative to the horizon. These angles are 60.degree., 45.degree., and 30.degree. respectively from the lowest to the highest solar cell mounting locations on the space frame. The support frame is protected from "shadowing" in both vertical and horizontal planes.

Abstract: Disclosed is a method and apparatus for sealing together two generally cylindrical thermoplastic members, each having a longitudinal axis, an open end and a closed end, so that upon being joined they form a sealed capsule that may be swallowed. One capsule member may be snugly inserted into a vibrating cavity with the opened end of the member available to be filled with an active composition. The other member is placed over the first member and pushed downwardly so that the open portions of both members overlap one another. The overlapping portions of the wall members abut each other at a cylindrical interface band. Vibration causes only the overlapping wall portions of the members to rub together, thereby generating heat around the interface band. The heat, so generated, melts enough thermoplastic material at that band to produce, on cooling, a strong circular bond between both members.

The device includes a first switching arrangement for selectively driving an electrical motor accommodated in the visor in a desired rotational direction to move the visor to an opened (projected) or closed (retracted) position from the closed or opened position, and a second switching arrangement for stopping automatically the rotation of the motor at a time when the visor reaches one of the opened and closed positions, whereby the operation of the device can be facilitated.

Abstract: The disclosure relates to a rotary indicating device preferably in use, for example, for wheel covers for motor vehicles. The device includes a base member adapted to be rotated about a rotary axis and having an indication region thereon. The indication region indicates a desired image and comprises a plurality of reflection faces. The reflection faces are inclined in the same direction and also at the same angle with respect to a standard plane perpendicular to a rotary axis of the rotary base member. Thus, when the base member rotates, the observer can visually recognize the image as a clear single image due to the after image phenomenon.
