Abstract: ABSTRACT OF THE DISCLOSURE          A folded package is produced by feeding a continuous web of a sheet material together with a strip of another sheet material along each longitudinal edge of the web and adhering the strips to the web such that each strip slightly projects beyond the respective edge of the web.  Intermittent areas of each strip are then provided with adhesive, the length of the adhesive areas corresponding to the length of the package to be produced.  Intermediate areas not provided with adhesive have the same length as those with the adhesive. Each strip is then turned over on itself whereby the portions of adhesive areas of each strip adhere to each other while the intermediate areas remain simply folded over but not adhered to each other.  The assembly is then cut transversely to form a blank including, at each edge, one adhesive and one non-adhesive area.  Adhesive is then applied to the top surface of the turned over portions of both strips along their entire length and the blank is then folded about its transverse center line to cause the respective halves of each turned-over strip to adhere to each other.  The invention increases productivity of production of bracing packages.

Abstract: ABSTRACT     A time variant filter system is employed for removing spurious noise content from a received seismic data signal.  The filter passband tracks delayed versions of the pilot signal of a vibrator seismic source.  The resulting recorded portion of the received seismic signal is thus restricted to a desired time-frequency band (which is expected to contain the significant mapping information) prior to being recorded.  The band is made adjustable in order to allow for optimization with respect to the particular geologic region being prospected.

Abstract: ABSTRACT An apparatus is disclosed for minimizing the horizontal forces on an offshore arctic structure due to ice movement.  The structure includes a base portion, sloped side walls and a smooth, unobstructed top portion. The structure is substantially submerged in a body of water with the top portion at or near the water surface permitting floating ice sheets which strike the side walls to flex slightly upward and advance along and over the structure without substantially destroying the overall integrity of the ice sheet.  In this manner, the horizontal forces on the structure resulting from the ice sheet are minimized due to the elimination of a crushing failure mode of the ice sheet commonly associated with conventional offshore arctic structures.

Abstract: ABSTRACT:           The invention related to a semiconductor cathode and a camera tube and display tube, respectively, having such a cathode, based on avalanche breakdown in a p-n juntion extending parallel to the surface of the semicon-ductor body.  The released electrons obtain extra energy by means of an accelerating electrode provided on the device. The resulting efficeiny increase makes the manu-facture of such cathodes in planar silicon technology sensible.  Since the depletion zone of the p-n junction upon avalanche breakdown does not emanate at the surface, the released electrons show a sharp energy distribution. This makes such cathodes particularly suitable for camera tubes.  In addition they find application, for example, in display tubes and flat displays.

Abstract: LIFT, TILT AND STEERING CONTROL FOR A LIFT TRUCK                 ABSTRACT OF THE DISCLOSURE          A lift truck hydraulic control system designed to conserve energy includes a pair of separately controlled pumps (21, 22).  One pump (21) supplies pressure fluid to a valve (12) for a steering cylinder (11) by way of a high priority port (34) of a priority valve (32) with the low priority flow passing to parallel connected lift and tilt valves (19, 18) which control operation of the lift cylinder (15) and tilt cylinders (16, 17), respectively.  The capacity of pump (21) is sufficient to provide proper, effective operation of the steering and tilt functions but is not adequate to provide hydraulic fluid flow for high speed expansion of the lift cylinder (15).  The other pump (22) is operated to supply additional pressure fluid flow for high speed lift only when the lift valve (19) is shifted to a raise position.  In one embodiment, a low speed lift is obtained by using the output of the pump (21) and a high speed lift is obtained by selectively adding the output of the second pump 22.  This is achieved by operating the other pump (22) only when the lift valve (19) is placed in an extreme raise position.  In another embodiment, the pumps (21, 22) are operated only "on demand," thereby further conserving energy.

Abstract: TITLE:   TOY WITH INTERLOCKING OBJECT          AND OBSTACLE         ABSTRACT      A toy has a housing in which is rotatably supported at least one disc having a plurality of object members on it.  The object members are fixed to the disc and therefore movable with it.  The toy includes a motor which drives the discs via a clutch. The clutch has two positions, one an engagement position wherein the disc is driven and the other a non-engagement position wherein the motor is no longer capable of driving the disc.  A movable member is mounted on the housing and positioned in association with the disc.  By moving over the surface of the disc, the movable member is capable of individually contacting each of the obstacles on the disc and upon such contact, the movable member is capable of inter-locking with each of the obstacles to stop the rotation of the disc and shift the clutch into the non-engagement position where it remains until other-wise acted on.  The toy includes a reset mechanism capable of disrupting the interlockment between the movable member and any of the obstacles allowing the clutch to shift from the non-engagement back to an engagement position and once again drive the disc.

The etching processes are substantially free of any loading effects and are characterized by high resolution, excellent uniformity and high selectivity with respect to, for example, silicon dioxide.  For silicon and undoped polysilicon, the edge profile of the etched material is anisotropic.  For doped polysilicon, the edge profile can be controlled to occur anywhere in the range from completely isotropic to completely anisotropic.

Abstract: Riser Angle Positioning System and Process Abstract A riser angle positioning system and process provides information for dynamically positioning a floating vessel (10) having a riser (12) extending to a wellhead on the ocean floor.  The system comprises an acoustic system (46) for generating acoustic data signals representing the position of the vessel with respect to the wellhead, top (42) and bottom (44) riser inclinometers for generating respective sensor signals indicating angles of deflection of the riser at the top and bottom, respectively, thereof, and a processor (40) responsive to the acoustic data signals and the sensor signals for generating positioning infor-mation.  The riser angle positioning system and process serve as a backup system and method for checking the acoustic data for large errors, and additionally provide the sole position determining system and method in case of acoustic black-out.  The riser angle positioning system and process have two alternative modes of operation: a simulator mode during which the vessel position is calculated from data read from a dynamic positioning system magnetic tape log, and a real time mode during which data is read directly from analog-to-digital converters associated with the top (42) and bottom (44) inclinometers and the acoustic system.
