Abstract: An illuminated sign which has a body (20) of extruded metal, which is rectangular in shape and held together at mitered corners with brackets (28) engaged into integral grooves (24). A pair of hinged sides are pivotally mounted onto the body, each consisting of an extruded casing (30) and a truncated translucent face (48) held in place by a plurality of retaining copings (56). The face contains raised or recessed indica which may be colored differently than the balance of the face. Lights are supplied inside the sign to allow illumination for visualization at night. The sides are so formed as to hinge on the top, as they are rotatably contained into the body with the other edges held into a locked position with an extended pointed lip (36) making the sign accessible inside and openable without external fastening devices, simplifying construction and service.

Abstract: A binder and angular stand for computer printout which has a bottom base (20) of rigid material with a pair of retainers (22) each having a slot (24) therein. A top cover (26) includes a hinge in the form of a pin (34) that interfaces with the slot allowing the cover to rotate and expand outwardly within the limitations of the slot. A hinged diagonal support brace (36) is rotationally attached to the top cover angularly extending by its own weight to form a support for the cover allowing printout to be retained and supported in both the open and closed position. A second embodiment is identical to the preferred, except somewhat simpler in construction utilizing a single brace (36a) in place of hinged members (38), (40), (42), (44), (46), and (48).

Abstract: A microstrip probe blade which has a ceramic body (20) with a microstrip (26) on one side and a metalized ground plane (30) on the other. A straight needle (32) having a tapered end and a spherical tip is attached to the microstrip axially and protrudes from the body parallel to the microstrip such that a high frequency signal may be conducted through the device with a minimum of electrical aberations. With this blade test, frequencies as high as 10 gigahertz may be achieved overcoming previous frequency limitations. The probe blade by virtue of the ground plane (30) wrapping around slightly to the microstrip side of the body (20) allows the addition of resistors (36) or chip capacitors (38) to minimize electrical spikes, transients, and unwanted opscillations to power supply frequencies.

Abstract: An expansion tap having a body (20) with a head (22) on one end and angularly tapered threads (26) on the other, with a bore (24) running therethrough. The body (20) has a shoulder stop (38) in the middle and a plurality of flutes (28) through the threaded portion. A capscrew (46) penetrates the bore (24) and is threadably engaged to a forcing cone (40) contiguous with the bore on the threaded end. A plurality of aligning ribs (44) engage the flutes (28), preventing rotation when the capscrew is tightened. The tap is inserted into a damaged threaded hole engaging the original threads in the middle and subsequently expanded by tightening the capscrew (46), thus straightening the tapered thread portion until the lands are parallel. Removal of the tap straightens and recuts the damaged threads.

Abstract: A continuity testing fixture for simultaneously probing of microelectronic chip site pads having a cluster of probe pins extending from a top plate in the same precise orientation as the pads. The probe pins are individually urged into compliance by a resilient pad disposed beneath the pins forcing a sharp end into contiguous engagement allowing an external signal to determine continuity of the workpiece. Individual insulated wires are attached to each probe on one end and are encompassed within a cavity in the body terminating at a connector near the edge of the fixture for linking to the remote test source. In another embodiment, the probe pins are hollow and contain an insulated wire allowing an independent signal to be introduced by way of the connector through the pads indicating both compliance of the probe and continuity of the workpiece simultaneously and independently.

A number of doors (42) are arranged in columns, each door having a spreader (46) rotatably attached and an integral tapered appendage penetrating the rollers upon pivotal rotation of the door. A coin carriage at the bottom of the stack allows the rollers (34) to drop freely a given distance, at least sufficient to allow penetration of only one spreader (46) when a proper combination of coins are introduced. The coin carriage employs a plunger block (62) and a pair of forks (66) to retain a number of spring loaded coin holders (64) each with a radiused cavity the appropriate size of the denomination.

Abstract: A vapor cycle refrigeration air chiller having two separate refrigeration systems in a single unitized frame. The first system producing a continuous cooling effect when supplied with alternating current power from an external source. The second refrigeration system operates to cool eutectic plates during alternating current operation. Air distribution is modified by a damper integral with a transporter containing the chiller and airborne food tray carts. Cooled air enters the carts from the chiller for pulldown and storage during alternating current operation. For transportation the chiller utilizes a self-contained battery operated, direct current fan with the damper spring loaded open, allowing the air to circulate over the eutectic plates and then around the food tray carts maintaining product temperature.

Abstract: A backgauge locator which provides manual adjustment of the backgauge relative to the die elements of a machine tool press brake. When used in pairs, each probe tip is contiguous with the outer edge of the workpiece to prevent parallel misalignment. The body is slideably attached to the machine tool backgauge to compensate for varying widths of the workpiece having an over-center spring loaded cam for manual positioning. A probe is pivotally located in the body and spring loaded to engage a micrometer head providing controlled linear movement. The probe pivots upward to allow for secondary bends of the workpiece without damaging the precision micrometer head and the tension spring also acts as a return mechanism to reposition the probe when the workpiece is removed.
