Abstract: ABSTRACT OF THE DISCLOSURE             A conveying and collection system adapted for drilling rigs for conveying drill cuttings entrained with a bailing air flow stream emanating from the drillhole includes a generally tubular head fitted around the drillhole having a flow deflecting surface portion adapted to deflect the flow stream of drill cuttings into a conveying enclosure whereby velocity reduction and change of direction of the flow stream will separate relatively coarse cuttings. A mechinical conveyor may be disposed in the enclosure to convey the cuttings to a point remote from the drillhole. The head may be extended and retracted with respect to the drill rig deck plate by actuators controlled in accordance with the conduction of bailing air to the drill stem. One embodiment of the head comprises an enclosure formed by overlapping helical convolutions of a flat spirally coiled band. The head may be provided with retractable gate members remotely actuated to move clear of an opening in the head which is of sufficient size to permit movement of drill stem coupling members and/or the drill bit through the head during drilling operations. A filter unit has a plurality of separate filter element chambers in which are disposes porous media filter elements arranged side by side along the path of a bailing air flow stream entering the filter unit housing so that the lower velocity portions of the flow stream are diverted into the filter element chambers and forced to flow in a vortical manner to provide inertial separation prior to flow through the filter elements. A suction pump on the filter unit is operable to vary its inlet volumetric capacity to provide a partial vacuum condition throughout the collection system to minimize leakage flow of dust laden bailing air out of the system.

Abstract: ABSTRACT OF THE DISCLOSURE      A ring encircles produce placed on a work table. Tie ribbon is fed by pressure rollers around the inner periphery of the ring to form a complete loop.  A first gripper clamps and retains the free end of the ribbon against a second gripper. The pressure rollers operate in reverse retracting excess ribbon about the produce.  A friction clutch, operative only for reverse ribbon feeding, allows for ribbon slippage as the ribbon tightens around the produce.  Then the second gripper clamps the other end of the ribbon against a twister head and a twister mechanism rotates the clamped ends of the ribbon about a common axis twisting the ribbon ends together. Shearing edges sever the engaged ribbon from a ribbon supply during twisting.  The grippers and twister mech-anism are at ends of concentric support rods and tubes, and the grippers in clamping move along the rotational axis of the twister mechanism.  Axial gripper motion is provided by cylinder valves having pistons concentric with and supported by the gripper support rod or tube and acting, respectively at the ends of the gripper supports away from the tie ribbon.   Rack and pinion mechanisms provide rotation of the twister mechanism and forward and reverse feeding of the ribbon.   All components are pneu-matically driven.  The design accommodates normal wear and tem-perature variations without adjustment.

Abstract: ABSTRACT OF THE DISCLOSURE           Apparatus  for protection against damage  from excessive torque loads, including a fast-acting slip clutch to limit torque transmitted between a drive motor and a mechanical load, and an automatic device to protect the slip clutch from damage due to slippage in excess of a predetermined amount for a predetermined time.  A slip measurement device detects the degree of slippage in the clutch, and a timing circuit coupled to the slip measure-ment device disconnects power from the drive motor after the predetermined time has elapsed.  In the illustrative embodiment of the invention, the slip clutch includes an input shaft, a wrapped spring in interference-fit engagement with the input shaft, and an output shaft in engagement with one end of the spring.  The spring tends to unwrap from the input shaft and to slip if a torque in excess of a threshold level is transmitted.

The system further includes an on-board vessel position computer (80) which operates in a differential Loran mode in response to observed Loran time differences, stored data from an initial calibration, and Loran grid offset data from an on-shore monitor system (22) to compute a highly accurate current or present position fix in longitude and latitude whereupon the computer (80) causes a predetermined electronic chart to be displayed in color on the screen of a cathode ray tube (94), being generated  from a plurality of elec-tronic charts (36) stored in the form of digital files in memory (30).  The selected chart, together with the present position of the ship (48), is displayed along with preselected alpha-numeric indicia (42) of data relating to bearings, way points, ranges, "time to go", etc., also generated in accordance with the computed vessel position.  Radar target returns of the local land mass (44) and other stationary/moving targets (52, 54, 56, 57) are additionally received by the ship's radar (26).  The radar image of the target echoes is next referenced to and superimposed on the electronic chart generated; however, the radar's land mass echoes are suppressed in favor of the elec-tronic chart land mass while displaying all other targets.

Abstract: ABSTRACT:     A method of manufacturing a semiconductor device, for example an SPS memory having narrow coplanar silicon electrodes.  The electrodes are formed by etching grooves or slots (10) having a width in the submicron range into a polycrystalline silicon layer (3), the slot width being defined by the oxidized edge (6) of a silicon auxiliary layer (5).  The electrodes are alternately covered by silicon oxide and by a layer comprising silicon nitride.          According to the invention, the electrodes formed covered by silicon oxide (3B, 13B) are first interconnected pair-wise, whereupon they are separated from each other in a separate etching step and are provided with self-aligned contact windows (15).  Thus, the very narrow electrodes can be contacted without technological problems and memory cells of very small dimensions can be obtained.

Abstract: Abstract Of The Disclosure An optical filtering system in which a signal beam of optical radiation is passed through the optical filtering means a multiplicity of times. The filtering system has an optical Fourier transform means, a spatial filter, optical inverse Fourier transform means and a pair of reflectors in the Fourier plane of the spatial filter. An input signal beam tube filtered is optically Fourier transformed by the transform means and is passed through the spatial filter where unwanted fre-quencies of the signal beam are attenuated. The filtered beam is reflected by one of the reflectors back through the filter and the second mirror reflects it back through the filter a third time. Subse-quent reflections back through the filter with a consequent further filtering of the signal beam can be accomplished by appropriately positioning the reflectors. After multiple filtering passes, the filtered beam is extracted for utilization. By maintaining the recursions of the beam in the Fourier plane of the filter, which preferably is of a programmable type, the optical throw of the filter system can be significantly reduced and a flexible imaging system without the restraints of external recursion is realizable in a robust structure with fewer components. An embodiment of the system being used in a heterodyning RF optical filtering system is described.

The carriage is movable parallel to the tie rods (or platen movement) of the molding machine to position a selected work station in register for mold changing.  There are rollers on the machine platens and at each carriage work station to support the mold weight while permitting lateral movement of the mold into or out of the machine or carriage as part of mold changing. Separate drive means to power such lateral mold movement are on each of the machine and carriage.  Each of the drive means select-ively moves a mold the first part of the way from the device in which it is mounted (i.e. machine or carriage) into the other device (carriage or machine) and at some point the drive means in the receiving device assumes driving and completion of the mold change.

In a preferred arrangement, the means for preventing release of the loading catch comprises a delay catch capable of interlocking engagement with the loading catch and having a projection which can enter a recess in the firing pin only when the firing pin is in the said rest position; the delay catch projection at other times bearing on the firing pin in such a manner as to maintain the said interlocking engagement effective.
