Abstract:
The invention relates to a heat exchanger housing (1) for at least one heat exchanger for exchanging heat between a first fluid, in particular an exhaust gas or charge air, and a second fluid, in particular a coolant (6). According to the concept of the invention, a bypass duct (40) is integrated in the heat exchanger housing (1), with the housing having a housing body (10) with a chamber which is designed to be traversed by the second fluid and to hold a number of flow ducts which can be traversed by the first fluid; a bypass duct (40) which is designed to be traversed by the first fluid; with the chamber and the bypass duct (40) being formed in one piece with the housing body (10).
Abstract:
A knife and chopping attachment assembly for chopping food products comprises a knife and a chopping attachment. The knife has a blade portion and a handle portion. The blade portion has a cutting edge and a spine disposed on a top side of the blade portion generally opposite the cutting edge. The chopping attachment is disposed over a portion of the spine of the knife. The chopping attachment is movable along the spine from a proximal end of the blade portion to a distal end of the blade portion.
Abstract:
A compact, optically fast catadioptric imager. In one embodiment, the catadioptric imager of this invention includes a first group of optical elements optically disposed to receive electromagnetic radiation from an object and having positive optical power, a second group of optical elements, optically disposed between the first group of optical elements and an image plane, having at least one optical surface and having positive optical power, a third group of optical elements, optically disposed between the object and the second group of optical elements, having at least one optical surface and having negative optical power, a fourth group of optical elements substantially centered along an optical axis of said second group of optical elements and having negative optical power, and a fifth group of optical elements having positive optical power.
Abstract:
An optical system including an array of micro-optic afocal optical subsystems capable of receiving electromagnetic radiation from a source and of transmitting at least a portion of the electromagnetic radiation received from the source, and an imaging subsystem capable of receiving electromagnetic radiation from the an array of micro-optic afocal optical subsystems and imaging at least a portion of the received electromagnetic radiation onto an image plane.
Abstract:
Notebook computer having a removable battery having a recess in one side, the side including an overhang over the recess to form an overhang recess. A pivoting latch has two arms, one of which extends into the battery recess and includes a lip extending into the overhang recess. A leaf spring biases the first arm into the battery recess. A second arm of the pivoting latch contacts a release actuator which pivots to counteract the leaf spring to allow the first arm to be removed from the battery recess. A spring at the rear of the computer biases the battery so that the lip is positively retained in the overhang recess so that simply depressing the release actuator does not release the battery. When the battery is pushed back to compress this spring, the lip can clear the overhang and depressing the release actuator results in the first arm clearing the battery recess so that the battery can be removed while the release actuator is depressed.
Abstract:
A portable computer system with the full functionality of a desktop computer is designed so that components are arranged in a highly space efficient manner. The main system unit includes a removable keyboard, a fold-up display screen, floppy and fixed disk drives, and an internal modem, and has both external AC and internal battery power supplies. The system further includes a desktop expansion base into which the main system unit can be inserted, providing additional functionality for the main system unit. The components of the system are arranged to provide a convenient and efficient user interface.
Abstract:
An ultrasonic transducer for emitting and receiving sound pulses is mounted within a fluid whose temperature is to be determined. The transducer is disposed in operative association with a first target which is mounted by a bimetallic coil so that it moves in a known manner with respect to the transducer in response to changes in temperature in the fluid. A stationary target is also provided disposed a fixed, known distance from the transducer, for calibration purposes. The transducer is mounted within a fiberglass tube, as are the movable and stationary targets. The tube may be mounted at the bottom of a liquid (e.g. gasoline) storage tank with the transducer facing upwardly so that both the level of liquid within the tank, and the density of the liquid as related to temperature, can be determined utilizing the transducer and a computer for acting upon the transducer output.
Abstract:
Disclosed is a heat exchanger, especially an exhaust gas heat exchanger, comprising a housing (101, 201, 301, 401, 501, 601, 702, 801, 901, 1101, 1401, 1501, 1901, 2001, 2101, 2201) which can be penetrated by at least one first medium (M1) and at least one second medium (M2), and at least one sealing element (213, 607, 707, 906, 1006, 1011, 1411, 1506, 2205). At least one flow means (217, 1507, 1507a, 1508, 1904, 2005, 2105, 2206, 2206a, 2206b), around which the second medium flows, is provided inside the housing, said flow means improving heat transfer from the first medium to the second medium.
