Title: Two-stage servo valve for pressure equalised main valve - has first stage with two sections of specified dia., with corresponding sectional piston and seat
Inventor: REIP RAYMOND G
IPC: F16K17/10
Filed: 1980-09-17
Abstract: The servo-valve has a first stage, controlling a pressure medium on exceeding a preset pressure, while the overpressure main valve is actuated by a second stage, responding to the flow through the first stage. The first stage has a piston with a first section of uniform diameter over a preset length, and a second section of uniform diameter over a second preset length, the piston forming a control member. On under-reaching a preset pressure, a seat cooperates with the piston, having two diameters corresponding to the two sections. The first piston section forms a throttle, with the first seat section, while the piston second section forms a second throttle with the second seat section. Thus, the vertical motion of the control piston provides a progressively throttling flow of the pressure medium.

Title: Machine for cutting circular plates - has two rotating circular cutters with upper cutter mounted forward of lower cutter
Inventor: TISATO ARNALDO
IPC: B23D19/04
Filed: 1980-10-25
Abstract: Circular plates are cut from square metal sheets by machines with rotating circular blades mounted one above the other. The axes of these blades are usually arranged so that they lie in a common vertical plane. A cleaner cut edge is produced if the upper blade (2) is moved forward of the lower blade (5). This forward movement is achieved by mounting the housing of the shaft driving the upper blade on a pivot so that it can swing through a limited angle in the horizontal plane. The housing movement is controlled by an eccentric cam so that the amount of offset can be varied as required. This arrangement of blades also reduces the risk of accident to the operator as it is less likely to pull the workpiece through the blades before the operator has released his grip.

Title: Photosensitive component for use in an electrophotographic copying process, and electrophotographic copying process
Inventor: NISHIKAWA MASAJI
IPC: G03G5/043
Filed: 1981-10-01
Abstract: A photosensitive component for electrophotography and an electrophotographic copying process employing the same are provided. The photosensitive component has a first and a second light-transmitting layer which are provided consecutively on a conductive substrate. The first light-transmitting layer consists of a material whose spectral sensitivity prevents an exposure during the irradiation with light for exposing the second photosensitive layer. According to an alternative, a filter layer is arranged between the first and second light-transmitting layer and prevents exposure of the first light-transmitting layer during the irradiation with light for exposing the second light-transmitting layer. The photosensitive component is subjected to a uniform charging step, an imagewise exposure step using light of a wavelength to which only the first light-transmitting layer is sensitive, and a uniform exposure step using light of a different wavelength to which only the second light-transmitting layer is sensitive in order to provide a latent image. The latent image is then repeatedly exposed to toner development and toner image transfer steps in the method as many times as corresponds to the number of copies to be produced. <IMAGE>

Title: Method for passively measuring the speed of a vehicle
Inventor: KRACHT GERHARD DIPL ING
IPC: G01S11/14
Filed: 1982-01-14
Abstract: The speed of a vehicle is to be determined by evaluating the radiated wave energy without disclosing one's presence. Dispersion characteristics of the transmission medium in the measuring area are utilised for the measurement in that the interference field coupled to the vehicle of the natural waves propagating in the transmission medium is measured by two transducers arranged at a distance from one another. Received signals of the transducers are subjected to a frequency analysis and intensities are stored in dependence on measurement time and frequency. A section of such an intensity pattern within a predeterminable frequency range and time interval of received signals of one transducer is brought to coincidence with an equally large intensity pattern of received signals of the other transducer by displacement with respect to time. The time displacement between the intensity patterns is a measure of the vehicle speed. The use of this measuring method is particularly effective in underwater sound applications.
