There is disclosed a sample and hold circuit using a four diode bridge using a voltage source and a bridge and a storage capacitor and the voltage source to be sampled coupled to the other two opposite nodes of the bridge. Switches in the lines coupling the voltage and current sources to the bridge control whether the sample and hold circuit is sampling data or holding the sampled voltage. This arrangement is characterized by extremely low sample voltage acquisition time.

A fish hold construction for a fishing vessel, wherein the vessel is provided with a longitudinally extending water flume fish alley. Fish move with the help of gravity and water or brine into such fish alley from a plurality of fish storage holds. Water or brine is continuously recirculated through the fish alley to urge the fish along such alley into a fish elevating conveyor for removal from the vessel. A 'tween deck located in vertical alignment with, and above, the fish alley houses pipes, ...

A track and hold circuit (1) comprising:--a linear amplifier (2) receiving a differential analog signal (D+, D-) and being controlled by a first binary clock signal (H+) having a first phase,--the linear amplifier (2) providing a feed-forward input signal substantially equal with the differential analog signal (D+, D-) to a pseudo latch circuit (3) in the first phase of the first binary clock signal (H+), said pseudo latch circuit (3) being controlled by a second binary clock signal (H-) for mem...

An ostomy garment comprises an undergarment having front, back and crotch panels, waist and leg bands stitched together to construct a typical panty or undergarment. The garment incorporates a retaining pocket and closure device. The retaining pocket has an opening defined by a crisscross arrangement which surrounds the connected flanges of an appliance and contains the appliance pouch apart from the user's abdomen.

A hold-down device for a mechanical dock leveler which is spring loaded so that when the hold-down device is released the deck will rise and the lip will extend. When the deck is walked down, the hold-down device maintains the deck in contact with the truck bed. This is accomplished by means of the interaction and geometry between a brake actuating arm and a brake release arm and the associated pins. As the dock leveler is lowered, the perpendicular distance from an anchor pin to the centerline ...

A single bolt hold-down bearing retainer device for a bearing assembly nested in a circular cavity of a cast housing. The retainer is in the form of a plate-like device having two adjacent linear edges intersecting at a radiused juncture defining an obtuse included angle. Each of the edges is formed with an upwardly angled locating tab extending in opposed relation to an associated housing wall portion. An attachment slot is provided in the retainer device intermediate the radiused juncture and ...

A power-off hold element for operating in cooperation with an actuator is disclosed. The power-off hold element comprises a material having selectively adjustable rigidity wherein a position or shape of said material is adjustable when energy is applied to increase the temperature of the material above a temperature where the material becomes flexible and the material is rigid in a position or shape when the temperature of the material decreases below the temperature where the material becomes f...

A hold down device and method for connecting two building elements of a building comprises an elongate member, typically in the form of a rod or a cable, that is connected between the two building structures. A tension compensator, which includes a housing, is mounted to the elongate member to compensate for wood shrinkage of the building. One end of the elongate member penetrates the housing and is releasably connected to the housing by means of a gripping assembly which permits only one way mo...

The antenna hold device comprises a transmitting and receiving antenna which can be stored within the main body portion of the antenna hold device, and a cylindrical-shaped antenna guide for guiding the main body portion storage side of the transmitting and receiving antenna. And, the present antenna hold device is characterized by clearance eliminating means which, when the transmitting and receiving antenna is guided to and stored in the main body portion storage side of the antenna hold devic...

An infinite sample-and-hold circuit which employs a DAC and an ADC coupled with a mode control circuit. In acquisition mode, the mode control circuit connects the analog input signal to the ADC. The ADC drives the DAC and when the DAC output equals the analog input, the mode control circuit disconnects the analog input and the DAC drives the output in hold mode. The mode control circuit preferably includes a comparator/buffer circuit including switching circuitry. The ADC is preferably of the su...
