Patent DE-3260732-D1 (DE)
Title: Apparatus and method for making thin-walled wax models for fine casting
Inventor: BRUGGER MANFRED
IPC: B29C67/24
Filed: 1982-09-13
Granted: 1984-10-18
Abstract: In order to remove a thin-walled wax model adhering to the walls of a first core piece and a second core piece, after solidifying, from a multi-part device for making thin-walled wax models, without damaging the wax model, after the external pressure is released, a mold-opening moment is generated simultaneously and abruptly in axially opposite directions by spring-loaded push-off bolts or directly by leaf springs in the upper parting faces and lower parting faces of the device. As a result, both the lower closing plate and the upper closing plate are separated from the annular casing and the wax model is separated from the core pieces, by a maximum of 3 mm, axially in opposite directions because the adhesion of the wax model to the walls of the core arrangements is overcome simultaneously and abruptly. Subsequently the two core arrangements and the casing are transported away from one another in an axial direction relative to one another, so that the wax model is freed.

Title: Tri-state driver circuit for automatic test equipment
Inventor: NECOECHEA WARREN R
IPC: H03K17/74
Filed: 1984-03-23
Granted: 1988-07-07
Abstract: A tri-state driver circuit (10) for selectively driving a node of a device under test by applying and switching between two reference voltages (DRH, DRL), and for selectively operating at a high impedance output state. Two current sources (16, 18) provide a bridge current that flows through a diode bridge (20) to establish, at nodes A and B, voltages that equal two reference voltages (DRH, DRL). The diode bridge (20) includes resistors (R11, R16) across which the bridge current is switched to accommodate small voltage swings, and also includes clamp diodes (CR3-6) to accommodate large voltage swings. A current switch (22) controls the direction of the bridge current and the selection of which of the two reference voltages (DRH, DRL) appears at node A. A current sink (36, 38, 40) monitors the average voltage of the diode bridge (20) and adjusts it to equal the average of the two reference voltages (DRH, DRL). A feedback circuit (42, 44, 46) monitors the higher of the voltages at nodes A and B and adjusts it to equal the higher of the two reference voltages (DRH, DRL). A transistor-diode bridge (48) operates as a buffer to generate an output signal equal in voltage to the voltage at Node A. A switch controller (50) switches the transistor-diode bridge (48) to a high impedance output state when so selected.

Abstract: A device for detecting a thickness variation of a piece of fabric passing under the presser foot of a sewing machine. The device includes a transmitter and receiver between which the fabric passes. The receiver stores maximum and minimum signals in memory units generated when the fabric passes between the transmitter and receiver.

Abstract: The invention relates to an optical device for measuring moisture in a substrate, in which device water is conveyed from the substrate along a porous absorption part (5) on a surface (4) of a prism so that is causes the critical angle of the total reflection to be changed thereon as a result of the change of the index of refraction. Another surface of the prism is dyed or patterned and covered in such a manner that it becomes visible only through reflection from the surface (4) when the surface is dry. When the surface (4) is moist, only the absorption part is visible through the viewing surface. The invention is advantageous in that due to the application of the principle of total reflection the change from an indication of the presence of moisture to an indication of the absence of moisture takes place sharply, not gradually.
