Title: Air-blasting cartridge
Inventor: SLEZ LEONID G
IPC: B08B9/04
Filed: 1988-06-14
Granted: 1992-03-10
Abstract: Abstract of the Disclosure An air-blasting cartridge comprises a housing subdivided into an inlet chamber and a discharge chamber by a piston arranged along its longitudinal axis. The inlet chamber com-municates with a source of compressed air through an air ad-mission tube which runs through an axial port of the piston.  The discharge chamber communicates with the inlet chamber through an annular gap 'between the air admission tube and the piston. The discharge chamber is adapted to communica-te with the surrounding atmosphere at the instant of its discharge. The area of the piston end surface facing the discharge chamber is greater than the area of the piston end surface facing the inlet chamber but is smaller than the area of the end surface of the collar on the piston that faces the discharge chamber, said collar forming, together with the housing, an additional chamber on the side facing the inlet chamber.

Inventor: KAATZ GARY F
IPC: H03L7/08
Filed: 1988-08-23
Granted: 1992-04-21
Abstract: Abstract For use in a radio synthesizer (110), a digital phase detector (118) indicates the phase error between a reference signal provided by a reference oscillator (117) and an output frequency signal (114) provided by a voltage controlled oscillator (112).  The digital phase detector (118) includes four flip/flops (310, 312, 314 and 316) which receive the frequency signals (116 and 120) provided by the oscillators (117 and 112) to generate steering signals (126) which optimally indicate the phase error between the frequency signals (116 and 120) as well as providing optimal (maximum) frequency steering when a frequency difference between the frequency signals (116 and 120) exists.  Responsive to the flip/flops, digital logic circuitry (306) is used to provide a non-integrated level-type indication when the frequency signals (116 and 120) are phase locked.

Abstract: An improved scanner is presented which enables a user to preview scan a picture and set out on a screen exactly what portion of the picture he desires to scan.  The scanner allows a preview scan of the picture to be made.  The preview scan presents a preview image.  The user is able to specify what portion of the picture he wants, by enclosing that portion of the preview image in a box.  Then the scanner performs a final scan which scans only the specified portion of the picture.  When performing the final scan, the user may select a percentage amount to reduce or enlarge the image when printed as a printed copy.  As the user changes the percentage amount, the dimensions of the resulting printed copy are displayed.  The dimensions are calculated by determining the dimensions of the portion to be scanned, and reducing and enlarging the dimensions proportionate to the amount the printed copy is reduced and enlarged.

Abstract: Abstract In heating reactors which in particular operate according to the principle of internal natural circulation, an afterheat removal circuit is connected to an intermediate circuit via at least one flow rate regulating unit which maintains a minimum flow through the afterheat removal cooler during afterheat removal operation.  The intermediate circuit connects a first heat exchanger inside the reactor to a second heat exchanger via a hot and a cold line, the cold line containing a pump.  According to the invention, a controllable element of power fluidics, a so-called vortex chamber valve with three hydraulic connections for the supply, control and outlet current, is used as the flow rate regulating unit, whereby the influx pipe of the afterheat removal circuit is connected to the hot line of the intermediate circuit via an internally controllable current path of the vortex chamber valve and the hydraulic connection for the control current is connected to the cold line on the delivery side of the pump of the intermediate circuit.  The invention also relates to use of the afterheat removal circuit with a vortex chamber valve in boiling water reactors or pressurized water reactors which serve to generate driving steam for steam turbo-generator units.

Abstract: With this circuit arrangement a plurality of control commands can be inputted into a microcomputer system by means of only a single input channel and the microprocessor is relieved of the operation of scanning the peripherals for detecting the presence of control commands. By means of a release or enabling signal the microprocessor signals its preparedness for receiving interruptions, and the release or enabling signal activates a scanning and comparator unit arranged between an interrupt requirement input of the microprocessor and a peripheral unit. Thereafter the scanning and comparator unit scans control command transmitters grouped together in the peripheral unit and characterized by an address and compares the switching state thereof with a switching state which is stored under the same address. If the two switching states are different, there is generated an interrupt requirement or requisition and the stored switching state is adapted to the switching state of the control command transmitter.

Abstract: @ A continuous, multi-phase process for debossing and perforating a substantially continuous web of substantially planar polymeric film to coincide with the image of one or more forming structures, each having a patterned forming surface with a multiplicity of holes and an opposed surface. Each forming structure is open from the holes in the forming surface to its opposed surface. The web of film has an indefinite length, a first surface, a second surface and a thickness. The thickness comprises the distance between the first surface and the second surface. The process comprises at least two sequential.forming phases, one of which involves three-dimensional conformance of the web to the macroscopic profile of the forming structure and another of which involves aperturing of the web to coincide with fine-scale apertures in either the same or a separate forming structure. The order in which the phases are carried out will depend upon the properties desired in the resultant macroscopically expanded, three-dimensional, apertured polymeric web. Because the process is carried out in sequential phases, previously incompatible characteristics which could not be provided by prior art single-phase forming processes can now be achieved.

Abstract: An apparatus for cutting hollow, metal, spirally formed pipes is disclosed. The apparatus uses two passive, rotatable knife blades to cut the pipe. An upper knife blade is positioned inside the pipe so that its cutting edge is adjacent to the inner pipe surface. A lower knife blade is positioned outside of the pipe so that its cutting edge is adjacent to the cutting edge of the upper knife blade in the lateral direction, but is clear of the pipe and upper knife blade in the longitudinal direction. To cut the pipe the lower knife blade is raised until its cutting edge overlaps the cutting edge of the upper knife blade. The knife blades then puncture the pipe. The pipe is rotated through the overlapping blades to completely cut the pipe. Since the pipe moves spirally (i.e., it moves forward while it rotates), the knife blades are adapted to move in the direction of the pipe during the cutting process. This permits the overlapping knife blades to cut the pipe rectangularly. The upper knife blade is attached to a cantilevered boom, and the lower knife blade is attached to a knife holder and a vertical raising device. These components are all attached to sliding guide rails so that they move with the cutting blades in the direction of the moving pipe during the cutting process.

Abstract: A shock absorber is electrically adjustable in a way to permit adaptation of the absorption to the type of road surface. The absorber comprises a cylinder with damping fluid, a piston with piston rod (2) displaceable in the cylinder, a sleeve (7) disposed in the piston and having two or more openings or series of openings (9, 10), two or more duct systems (15 to 18; 19, 20; 22 to 26) of differing damping characteristic being disposed in the piston. Each duct system connects to an opening or series of openings in the sleeve. Electrically operated control means (11) are present to close off or release one or more of the openings (9, 10) in the sleeve. To make the shock absorption adjustable over the entire speed range of the piston both at high and low piston speeds the control means (11) alone determine via which duct system the damping fluid can flow through the piston, while the openings or series of openings (9, 10) in the sleeve are so large that they do not essentially effect the shock absorption.
