Disclosed is a method of determining the optimal spacing of seismic receiver lines, including marine streamers. A weighted squared error function is defined between a desired array response function and an actual response function, and the error function is minimized to determine the values of crossline offsets between streamers as well as the depths of the streamers in a configuration to minimize out-of-plane signal effects, for example.

Method of determining optimal seismic multistreamer spacing

Disclosed is a seismic surveying and data processing method to filter from seismic data any energy contributions that are not in the seismic line of profile. The surveying method requires a receiver geometry wherein at least one receiver is in and at least one receiver is out of the line of profile, so that in common offset gather or shot record plots, seismic events along the line of profile are aligned in time and out-of-plane energy takes the form of a series of sawtoothed seismic events arriving at different times in the different lines of receivers. Knowing the number of out-of-plane energies and their respective dips allows for the design of a filter, which is applied to the data with a computer, to null and thereby remove the effects of unwanted out-of-plane energy from the seismic survey data.

Advertising display apparatus

An advertising display apparatus comprising a base, means on the base for holding condiments, a plurality of support members on the base, each facing in a different respective direction, means for mounting at least one advertisement on each support member, means mounting the support members for movement relative to the base to change the direction in which a given advertisement faces. A hollow, transparent tube having a plurality of walls constitutes transparent cover means for enclosing and protectively covering the support members. Each support member and its respective advertisement faces a respective wall on the tube. A resilient, strip-like member is located within the tube and is resiliently deformable between an expanded, open first condition and a second condition in which it is at least partially closed for urging the advertisement toward its respective wall on the tube. The apparatus is preferably displayed on restaurant tables so that customers can view the advertisements during their meal. The tube is of a size which preferably accommodates twelve business cards; three cards per support member.

A display apparatus for displaying a plurality of advertisements comprising a base, which holds condiments and comprising a plurality of condiment holding sections separated from each other by the display apparatus, support members on the base for displaying a plurality of business cards with each of the business cards facing in a different respective direction. The cards are removably mounted and the display apparatus is mounted for movement relative to the base to change the direction in which a given business card faces. A transparent cover, removably mounted to the display apparatus, protects the business cards on the display apparatus and comprises a single integral member comprising a hollow, vertically disposed tube having four walls and having a rectangular horizontal cross-section. A plurality of vertically disposed support members or sections each facing in a different respective direction are protectively covered by the transparent tube. At least one business card is mounted to each support member. The support members are disposed on the inside of the tube, one support member facing each of the four walls of the tube. A resilient, strip-like member is located within the tube and is resiliently deformable between an expanded, open first condition and a second condition in which the strip-like member is at least partially closed for urging the advertisement on each support member toward its respective wall on the transparent tube. The apparatus is preferably displayed on restaurant tables so that customers can view the advertisements contained therein during their meal. The tube embodiment is of a size which preferably accommodates twelve business cards; three cards on each support member.
