Abstract: ABSTRACT       To determine whether or not all of the required holes have been formed in a multiple-hole workpiece, as by a punch press, the workpiece is placed in an inspection arrangement containing a system of multiple mirrors adapted to reflect a laser beam from a laser beam source through the multiple holes in the workpiece to a laser beam sensor which preferably is electrically connected to an acceptance or rejection indi-cator or actuator or to the press control system.  If all of the holes have been properly punched or otherwise formed, the sensor recognizes that fact and permits the next workpiece to be fed to the press and the inspected workpiece to be conveyed onward as accepted.  If, on the other hand r one or more of the holes have not been punched or otherwise formed, the passage of the laser beam is blocked, so that the workpiece is reject-ed by the sensor and its connected workpiece handling system, and at the same time, the press control system halts the press and prevents the workpiece handling mechanism from supplying another workpiece to the press until the rejection has been overcome.  In a modification, the inspector is built into the press equipment itself, whereby the upper and lower dies of the press are provided with the laser beam source and sensors, also with passageways containing the multiple mirrors, and operating similarly as above described.  The lower die is also provided with scrap slug disposal passageways for carrying away the slugs punched out of the workpiece placed between the upper and lower dies.

Abstract: ABSTRACT OF THE DISCLOSURE        The invention provides a hydraulically driven reciprocatory tool comprising a piston with a shoulder reciprocable within a cylinder, the space within the cylinder on one side of the shoulder being maintained at high pressure, and the space on the other side of the shoulder being maintained at low pressure.  The piston is driven against a constant bias force by means of pressure fluid by means of which a driving force is cyclically applied to the piston under the control of a shuttle valve. The shuttle valve position is controlled by the axial position of the piston in the cylinder as sensed via the pressure of fluid in a signal line connecting the shuttle valve with first and second ports in the cylinder wall.  The signal line has non-return valves for preventing flow of fluid from the shuttle valve to the first port, and from the second port to the shuttle valve.  The driving force is applied to the piston via a duct in part of the cylinder body which projects into a recess in the piston.  The projecting part can form a sliding seal with the recess to form a fluid tight enclosure in which the pressure of driving fluid can bear cyclically on the end of the blind bore.  Alternatively the driving pressure fluid can act cyclically on a rod piston slideable in the duct within the projecting port so that the rod bears on the end of the blind bore,  Preferably each non-return valve has associated therewith a variable throttle in the signal line, and according to a further preferred feature, means are provided for the controllable flow of fluid to or from the signal line.

Abstract: SAWMILL LOG-HANDLING SYSTEM                 Abstract of the Disclosure Logs are advanced through a saw while they are engaged between driven pusher dogs and retarded hold-back dogs.  The pusher dogs are mounted on a lower endless roller chain below the logs, and the hold-back dogs are on an upper endless roller chain above the logs.          The upper chain and its hold-back does are vertically movable to elevations dependent on the elevation of a log, thus assuring proper engagement.  When the sawed portion of a log is retained laterally on a support, the hold-back dogs are moved forwardly away from the log so that a hold-back dog will be in the path of the next log to be handled by the system.

Abstract: ABSTRACT OF THE DISCLOSURE Brine (aqueous solution of alkali metal chlorine) which is electrolyzed according to the amalgamation process, generally contains small amounts of mercury.  It has been found that these traces of mercury are entrained to a considerable extent with evaporated water when evaporation cooling is applied to the brine.  In order to keep these losses as low as possible, the pH is adjusted to a value of from 7 to 9.8 and the redox potential is adjusted to a vlaue of from 800 to 1100 mV (based on the potential of the hydrogen electrode) by adding chlorine or alkali metal hypochlorite and optionally alkali metal hydroxide to the brine.

Abstract: ABSTRACT         Zeolite catalyzed reduction of nitrogen oxides in exhaust gases is conducted with catalytic elements in the form of multi-channel structures in which parallel channels are defined by thin walls constituted by refractory oxides having zeolite dispersed therein and accessable to diffusion from surfaces of the channel walls.  Such structures, preferably monolithic honeycomb forms, are prepared by calcining extruded or cast forms of kaolin at elevated temperatures and treating the calcined kaolin honeycomb with a caustic solution to develop a desired zeolite within the wall members and etch the wall surfaces to provide diffusion paths to and from the embedded zeolite.  Such structures are peculiarly suited to high space velocity processes such as reduction of nitrogen oxides in providing for protection of the zeolite catalyst against erosion by high velocity gas streams while also providing adequate diffusivity for reactants at the high space velocities typical of the known reaction between oxides of nitrogen and a reducing agent such as amnonia.

Abstract: ABSTRACT OF THE DISCLOSURE         An orifice plate for a glass fiber drawing bushing having a flat undersurface and a number of orifices formed through the orifice plate, in which longitudinal and transverse parallel grooves are formed on the undersurface of the orifice plate in such a way that the undersurface is divided by the longitudinal and transverse grooves into a number of square sections within each of which is located one of orifices.  In this way the orifice plate is deformed just as having tip nozzles in a shape of quadrangular prism and therefore the pitch of orifices arranged in the orifice plate may be made as small as in conventional tip nozzles.          When the grooves are formed in the undersurface of a closely spaced orifice plate which requires to blow cooling air against the undersurface of the orifice plate so as to prevent flooding of the undersurface by molten glass and ensure stable glass fiber drawing operation, the orifice plate may be used for drawing finer glass fibers which cannot be drawn with conventional closely spaced orifice plates without grooves.

Abstract: 915,123 ABSTRACT     A cartridge (10) for use in a disk drive machine.  The cartridge (10) includes a compression spring (24) for biasing a plunger (22) to a storage position against a memory disk assembly (14), frictionally restricting the disk assembly (14) within the housing (12) when the cartridge is removed from the machine.          Additionally, the cartridge (10) includes an access door (26) coupled to the plunger (22) by a tension spring (34) which will bias the door (26) to a fully closed position when the plunger (22) is in its storage position, and also bias the plunger (22) against the compression spring (24) to a retracted position spaced from the disk assembly (14), permitting rotation of the disk assembly (14) when the door (26) is opened by a disk drive machine.  The use of this structure is a simplification of the prior art which also eliminates the tendency of the access door to warp and thus ineffectively close.

Abstract: ABSTRACT OF THE DISCLOSURE Aqueous protein dispersions obtained from vegetable sources are subjected to successive pressure and cavitation cycling (e.g., centrifugal homogenization) at temperatures below the protein heat denaturization and under slightly alkaline pH's (e.g., pH 7.0-?.0) to provide a high NSI product. These high NSI products may be dried to provide a vegetable seed product having functional properties and utility similar to milk proteins. Buffered salt extracts from such spray-dried products reveal a predominant restructuring of the protein constituents into high molecular weight protein aggregates. Low NSI soy concentrates obtained by aqueous alcohol extraction processes are converted into a high NSI product possessing many of the desirable functional attributes of soy isolates plus those of milk proteins.
