Abstract: A pump assembly is fluidly coupled to a vehicle engine for moving a fluid. The pump assembly includes a pump housing and an impeller disposed in the pump housing for moving the fluid in the pump housing towards an outlet. Additionally, the pump assembly includes a valve assembly integrated with the pump housing. The valve assembly includes a barrel disposed in the pump housing and having at least one inlet, wherein the at least one inlet is configured to provide controlled flow of the fluid into the pump housing. A sleeve is rotatably coupled to the barrel for selectively controlling the flow of the fluid into the at least one inlet of the barrel. Additionally, the valve assembly includes an actuator assembly operably coupled to the sleeve and configured to rotate the sleeve between a first position and a second position.

Abstract: The present invention relates to an apparatus for converting electrical energy for conductively heating rod-shaped semiconductor materials. The apparatus is particularly useful to control the temperature of electrically heated rods in the Siemens process for deposition of silicon by chemical vapor deposition.

Abstract: A process and device for the output of electronic image signals on light-sensitive recording material is disclosed. A two-dimensional, transmissive display element, in particular a liquid crystal display (LCD), is controlled by the image signals and the beam of at least one light source passes therethrough in the direction of the light-sensitive recording material. During video output, the display element is arranged so near to the recording material that a sharp picture is produced on the recording material without having to position additional focusing, optical means between the display element and the recording material.

Abstract: A device for winding strips of photographic film inside a housing. A film-guide slot opens into the housing's approximately cylindrical interior. A film reel rotates freely in the housing interior without a positive drive and demarcates, in conjunction with the inner surface of the housing, a more or less annular film-guide channel. The film-guide slot opens more or less tangentially into the interior channel.

Abstract: A microfilm reading and reverse enlarging apparatus with a copying beam for a gap illumination comprises a copy carrier movable with a constant speed, drive device for moving the copy carrier, a film platform for a film and adjustable relative to an illuminating beam, transporting device for reciprocating the film platform synchronously with the movement of the copy carrier, control device for controlling the transporting device, a potentiometer adjustable by the transporting device synchronously with the movement of the platform so as to produce respective values in response to the movement of the platform during a copying process of successive microimages, and storing and comparing device arranged to store preselected values and to receive the values of the potentiometer to compare them with the preselected values, the storing and comparing device being connected with the control device so that the transporting device and the drive device for the copy carrier during reaching by the values of the potentiomet

Abstract: A device for controlling the width of a slot of a diaphragm of a microfilm-reading-and-copying apparatus in which an enlarged microimage is projected by two inclined mirrors mounted on a movable carriage and via the slot of the diaphragm on a copying cylinder. The diaphragm is formed by two flaps of which one is stationary and another one is movable between a closed position to close the slot and a plurality of open positions to adjust the width of the slot. The drive of the movable flap is provided with a rotatable cam which is coupled to the movable carriage.

Abstract: A safety belt is adapted to be applied to a person who occupies a seat. Belt-fixing means are adapted to releasably hold said belt in position for retaining such person on said seat when said belt is applied to such person. First and second control elements are movable relative to each other in a predetermined direction to an enabling position in response to a tensile load on said belt in excess of a predetermined value. Detent means are arranged to prevent a movement of said first and second control elements relative to each other out of said enabling position opposite to said predetermined direction. A drive spring is connected to said first and second control elements and arranged to be stressed as they move in said predetermined direction. A retarding mechanism is adapted to perform a predetermined stroke under the action of said spring when said first and second control elements are in said enabling position.
