An active load circuit that includes a diode bridge having first through fourth nodes, wherein a voltage buffer is connected with the first node, a source current mirror is connected with the second node, the third node is configured for connection to a device under test (DUT), and a sink current mirror is connected with the fourth node. A first current mirror is connected with the source current mirror, and a second current mirror is connected with the sink current mirror. A first differential pair is connected with the first current mirror and includes an input connected with the DUT and a second input connected with the input voltage. A second differential pair is connected with the second current mirror and includes a first input connected with the DUT and a second input connected with the input voltage.

Low power active load

A multidirectional runner assembly for positioning a carrier pipe within a surrounding casing pipe. Each multidirectional runner assembly has at least one ball transfer assembly at least partially protruding from the runner assembly, in order to contact an inner surface of a surrounding casing pipe. The ball transfer assemblies reduce static and/or kinetic friction forces during installation of a carrier pipe within the central bore of a casing pipe, permit multidirectional orientation of the runners within the casing pipe, and provide greater load support.

An integrated circuit for measuring a signal, including a parametric pin measurement unit (PPMU) that sends a forced signal, the PPMU having a first amplifier, a second amplifier with an output terminal connected to the input terminals of the first amplifier through a common resistor; a voltage-to-current convertor connected to a PPMU output and having a first output and a second output; n channel MOSFETs connected to the first output of the voltage-to-current converter; p channel MOSFETs connected to the second output of the voltage-to-current converter; a buffered amplifier connected to an output port between the n channel MOSFETs and the p channel MOSFETs; and a resistance divider connected to the output of the buffered amplifier.

A wall mounted urinal has a detachable urinal insert where the insert provides a frontally directed opening for receiving a urine stream. The insert provides a lower surface in contact with the bottom surface of the urinal for supporting the insert, and an upper surface or a rear surface, or both, for stabilizing the insert within the urinal. A splash capturing surface defines an aperture for admitting a urine stream, the aperture comprising an area inferior to that of the frontally directed opening of the urinal and extending outwardly from it.

A copy holder having a slotted beam sized to accommodate paper copy has locking means in the form of a cylindrical bearing held partially within the slot of the beam to provide weighted pressure against paper held within the slot. A paper back support is hinged to the slotted beam which is pivotally mounted to a support bracket which is slidably received in a mounting bracket secured to a monitor or other object.

A printer stand for support of a printer having a pair of spaced apart parallel bars which are supported by stanchions. A pair of spaced apart cantilever support arms having cross members for bracing are detachably secured to the stanchions. A paper catch tray is detachably mounted on and supported by the cantilever support arms. The height and width of the printer stand are adjustable to accommodate different sizes of printers.

A magnetic disk storage case, having a boxlike portion with side and front walls, hinged by means of a binding to a top that overlies the boxlike portion. Attached to the binding is an articulated support ledge or shelf which is molded to the binding as well as the boxlike portion and the top in one injection molding process. The ledge or shelf is provided with two lateral tabs which extend outwardly through openings within two wall bracket portions depending from the top so as to allow the ledge to move backwardly and forwardly with the tabs being secured for their respective movement within the openings. This permits the ledge to be moved to a limited degree for expanding the space between the ledge and the interior surface of the top so as to provide greater access to magnetic memory disks stored on the ledge and held within the case.

Apparatus for thawing a pipe having a frozen blockage therein, the apparatus including a self-contained unit on wheels, the unit including a tank for holding water, an electric immersion heater in the tank for heating the water to a temperature of 100.degree.-150.degree. F., a pump supported on the unit, a foot switch connected to the pump, a pressure control connected to the pump, a reel of flexilbe polyurethane hose and a reel of return hose mounted on respective sides of the tank, and a conical coupling for connecting to one end of the frozen pipe, the coupling including a compression fitting for engaging around the flexible hose, and a T-shaped return fitting for connecting to the return hose. The flexible hose is pushed through the compression fitting towards the frozen blockage and emits a stream of water under pressure from the pump that erodes and eliminates the frozen blockage, and return water is pushed from the blockage back to the return fitting and through the return hose to the container thereby providing a closed loop system. A pressure relief and bypass valve connects the outlet side of the pump to the container through a bypass line. The system operates on ordinary house current. The closed loop system provides for no fluid leakage between the pipe, hoses and the container.

Electrically heated pipe thawing apparatus

The following specification discloses a magnetic disk storage case that can be used for such disks, as well as other magnetic memory materials common to computers and word processing. The storage case is formed from a single molded piece of plastic, such as polypropylene in the form of a clamshell or book-like case, having a top and bottom cover. The top cover receives a support ledge having flexible barriers thereon to maintain the magnetic materials stored therebehind on the ledge. The bottom of the case receives the ledge and the magnetic disks therein within a surrounding wall. The entire top cover with the ledge and the disks therein can be accessed by means of a resilient living hinge that allows for the lid to be opened into a clamshell configuration and supported against a stop member, against one of the edge walls, or by means of a channeled arcuate groove in combination with a pin that functions therewith.
