Abstract: A screen is mounted in an apparatus for contacting particulate solids with a fluid. The apparatus comprises an elongate column for holding a bed of particulate solids for contact with a fluid, t:he column being designed to be oriented substantially vertically in use and having a fluid inlet near the bottom for admitting a fluid into the column and a fluid outlet near the top for permitting the fluid to. exit the column after passing upwardly through a bed of particulate solids in the column. The purpose of the screen is to screen solids from the fluid exiting the column through the fluid outlet. The screen comprises a plurality of vertical screen wires. and the screen is located within the column such that all of the fluid passing through the column passes through the screen and thence through the fluid cutlet. Each pair of adjacent vertical screen wires defines a substantially vertical screen slot therebetween. The opening of each vertical screen slot at the surface of the screen which is upstream in the sense of a fluid flowing through the column. passing through the screen. and exiting through the outlet during operation of the column, has a width suitable for screening solids from the exiting fluid and has a length which is substantially greater than its width.

Title: A.c. power controller with short circuit and overload protection
Inventor: IONESCU ADRIAN
IPC: H02H3/08
Filed: 1990-06-12
Abstract: A.C. POWER CONTROLLER WITH SHORT CIRCUIT AND OVERLOAD PROTECTION                     ABSTRACT OF THE DISCLOSURE         An A.C. solid state power controller for controlling the current through a load from an alternating current source, including a diode bridge rectifier with its direct current output connected to a solid state switch, such as a MOSFET or a bipolar transistor, that is gate controlled by gate signals synchronized to the A.C. source.  The gate signals are provided from an optocoupler to control the solid state switch and the load current.          Overload, short circuit, and low A.C. line voltage conditions are sensed by protection circuits which signal the optocoupler to turn off the solid state switch and, thus, the load current.          A fast turn off time, in the range of a few microseconds, is achieved which, together with the rectifier and solid state switch configuration, provides a power controller which is resistant to short circuit and overload destruction present in conventional A.C. solid state circuit  breakers and power control devices.

Abstract: A multiple beam space antenna system for facilitating communications between a satellite switch (100) and a plurality of earth-based stations (1,a,b,) is shown. The antenna is deployed after the satellite is in orbit by inflation of a raft-type supporting structure which contains a number of antenna horns (80). These antenna horns are oriented in substantially concentric circular groups (A-D) about a centrally located antenna horn (80). Each of the antenna beams projects an area on the earth. Each of the areas (a,b) of the beams are contiguous. As a result, one large area is subdivided into many smaller areas to facilitate communications. In addition, a lens (FIG. 7C and 7D) may be employed to focus the beams of the horn antennas.

Title: Segmented mirror and method of controlling the same
Inventor: ULICH BOBBY L
IPC: G02B26/06
Filed: 1990-11-06
Abstract: SEGMENTED MIRROR AND METHOD OF      CONTROLLING THE SAME            Abstract of the Invention:    A segmented mirror control system is-presented wherein an array of structural elements (e.g. mirrors) can be actively positioned to maintain an accurate pre-determined overall shape.  The present invention is "active" and so may be characterized as an Active Segmented Mirror Control "ASMC". The segments of a mirror or the reflecting panels, in for example, a radiotelescope, may be continually adjusted with ASMC to provide an accurate reflecting mirror of very large diameter even when disturbed by external forces.  ASMC is a closed loop control system.  That is, an array of sensors is first used to measure differential position errors.  This data is then processed to determine position actuator commands.  Finally, these commands are used to move the segments until the sensors are nulled and the desired shape is obtained.

Title: Photographic attachment and shutter device for a binocular microscope
Inventor: PAPRITZ FRANZ
IPC: G02B21/18
Filed: 1990-05-10
Abstract: The housing (10), which is inserted between the magnification selector (7) and the ocular tube (8) of a microscope, accommodates a pivotable mirror (22) which is normally placed outside the beam path of the microscope, but which by actuating a lever (17) can be pivoted into the beam path in order to deliver the latter through a photo cone (13) to a camera (14).  By actuating the lever (17), the camera (14) is released after the required chronological delay in order to take a picture of the object, e.g. an eye (4).  A diaphragm arrangement, which can be brought into the preselected position for the exposure as well by actuation of the lever (17), is disposed at the entry of the housing (10), i.e. directly adjacent the magnification selector (7).  Due to the full availability of the light and the advantageous position and adjustability of the diaphragm, optimum conditions exist both for observation and for photographical exposures.

Abstract: ABSTRACT OF THE INVENTION     An apparatus and method for extracting juice from raw juice containing material is disclosed.   The apparatus includes a supporting housing,  a pair of meshing helical gears 2,3 for crushing the raw juice containing material to initially extract juice therefrom and with each helical gear terminating in a tapered screw.  A sieve 4 is operatively positioned around the helical gears and each of the tapered screws with the sieve being branched 47,48 with each branch housing at least a portion of one of the tapered screws, respectively.  Each branch of the sieve has a terminal end with a discharge outlet formed thereat to enable each of the screws to further extract juice from the crushed raw juice containing material by compressingly moving the crushed  juice  containing material  along  one of  the  branch portions of the sieve and toward one of the discharge outlets formed in the sieve.   An outlet disc 7 is positioned at the discharge outlets and is biased in a closed position thereby taking advantage of the compressive forces to further squeeze juice from the crushed material until the force tensioning the tensioned outlet disc is overcome and such material is discharged from the housing.  A power means 1 supplies rotational output to the helical gears and the tapered screws.
