Abstract: The present invention relates to a blind apparatus of the lighttracking type and comprises an intensity detector portion (D) for detecting the amount of light illuminance and a light direction detector portion (P) for detecting the direction from which light is coming. By processing the respective signals from these detecting portions, rotation angles of the blades of the blind apparatus are controlled. Therefore, the blades of the blind apparatus can be automatically adjusted so as to always become most perpendicualr to the direct rays of the sun or other sources of light.

Abstract: A method and apparatus for automatic inspection of periodic patterns typically found on patterned silicon wafers, printed circuit board, and the like is dis­closed herein. The method comprises an inspection algorithm of two parts: a low-level algorithm and a higher level algorithm which includes, therein the operation of the low-level algorithm. The low-level algorithm utilizes the known periodicity of the pattern to find defects by comparing identical cells in the periodic array. The high-level algorithm comprises applying the low-level algorithm, some number of times (N) in succession on the image. An accumulator image is formed by adding the results of the low-level algorithm to create a separate image array where the pixels in the original image was detected as defective by the low-­level algorithm. 
     The apparatus for implementing the above method comprises a parallel/pipeline architecture for high speed processing and RAM LUTs to implement a plurality of substract and compare functions.

Abstract: Analysis of[¹²⁵I]. interferon gamma cross-linked to its receptor on various human cells by SDS-PAGE revealed that there are at least three different types of human interferon gamma receptors. In WISH, HeLa, FS11 and other tissue cells an Mr 90,000-105,000 receptor was found. In monocytes and in the myeloid cell line KG-1 an Mr 140,000 receptor was found while in Daudi lymphoblastoid cells an Mr 95,000-115,000 receptor was found. 
     The various receptors were isolated from these cells by extraction followed by affinity chromotography on an immobilized interferon gamma column. The resulting purified preparations retained their original affinity for interferon gamma and were used for immunizing mice and subsequent development of highly specific antibodies.

Abstract: Hair is waved or straightened by maintaining it in tightly curled or in straightened configuration in contact with an aqueous waving lotion containing sulfite, bisulfite, or hydrosulfite together with a water-soluble mercaptan, at a molar ratio of 5:1 to 1:7.5, rebuilding with an aqueous lotion at pH 7 to 12 free from cross-linking, oxidizing, or reducing agents, and subsequently applying a neutralizer solution. Minimal damage to the hair results from use of the specified molar ratio. When waving hair, an optional additional step between cross-linking and neutralizing comprises maintaining the rebuilt hair in stress-free condition in contact with the ambient atmosphere to permit the curled hair to relax to the desired extent.

The mounting apparatus (4O) comprises a spacer member (42) which engages both the upper surface (37) and the lower surface (38) of the transmission casing (35) to provide radial support thereof and also engages the inner race of a bearing assembly (41) rotatably mounting the idler gear (34). A bolt (46) having a head portion (47) received within a recessed portion (45) of the spacer member (42), extends through the spacer member (42) and is threadably engaged with a securing member (48) which in turn engages the lower surface member (38)of the transmission casing (35). A lip portion (43) of the spacer member (42)engaged with the upper surface (37) of the transmission casing (35) permits the mounting apparatus (4O) to be secured between the upper and lower surfaces (37, 38) of the transmission casing (35) and rotatably mount the idler gear (34). 
     Also an improved disc cutter rotor assembly (25) for use in a disc cuttebar (2O) of the type utilizing a plurality of intermeshed gears (3O) to transfer rotational power is disclosed. This rotor assembly (25) provides a lower profile to facilitate the flow of crop material over the cutterbar (2O) and yet also permits the individual components of the rotor assembly (25) to be serviced and/or replaced. The hub (62) and shaft (6O) are of welded construction and are rotatably mounted via a removable bearing assembly (57) within a bearing housing (55) affixed to the transmission casing (35). The drive gear (32) for the rotor assembly (25) is splined onto the shaft (6O) and retained in place by a fastener and washer assembly (65) to permit the drive gear   (32) to be removed from the shaft (6O).

Abstract: Apparatus is described for aligning objects; for example: a circular semiconductor wafer having a flat, one example of a surface with a distinguishing feature. Rotator means hold and rotate the object about a rotation axis so that a portion of the surface including the distinguishing features travels through a surface sensing region. Engage­ment means engage the object and transfer it to and receive it from the rotator means. Sensing means measure and record, during rotation of the object, position versus angular orientation information relating to position of the surface along an axis transverse to the surface. Calculating means are responsive to the sensing means and calculate, from the position versus angular orientation information, the angular orientation of the distinguishing feature and/or the location of the centre of the object with respect to the rotation axis. Alignment correction means generate angular correction signals for rotating the object such that the distinguishing feature attains a predetermined angular orientation and/or generate alignment signals for aligning the centre with respect to the rotation axis.

Abstract: A fuel control apparatus for a fuel injection system of an internal combustion engine (1) has an air flow sensor (13) for sensing the air flow rate into the air intake pipe (15) of the engine and producing an electrical output having a frequency which is proportional to the air flow rate, and a crank angle sensor (17) for producing an electrical output pulse each time the crank shaft of the engine is at a prescribed crank angle. A load detector (20) detects the number of output pulses from the air flow sensor (13) between consecutive output pulses of the crank angle sensor (17), and an air flow rate calculator (21) calculates the actual intake air flow rate into the cylinders of the engine based on the output of the load detector (20). A controller (22) controls the supply of fuel to fuel injectors (14) for the engine (1) based on the output of the calculator (21). The load detector (20) includes a frequency divider (31) which performs frequency division of the output from the air flow sensor when the load exceeds a prescribed level.

Abstract: A gas turbine engine control system which regulates fuel flow based upon a schedule which is a function of a primary parameter, such as engine pressure ratio, switches to a schedule based upon a secondary parameter, such as compressor speed, upon the inability to function in the primary parameter mode. Upon switchover to the secondary parameter mode the scheduled value of the secondary parameter is down-trimmed to make it equivalent to the last known good value of the primary parameter so that the engine will not experience a sudden change in power level upon switchover. The down-trim is limited. When the primary mode failure occurs during a transient the down-trim is limited to the difference between a scheduled reference value of the secondary parameter and a value of the secondary parameter calculated immediately preceeding loss of the primary parameter mode and based upon a known relationship between the primary and secondary parameter. The down-trim limit assures a smooth transition from the primary to the secondary control mode when switchover occurs during an engine transient.
