Abstract: A one-column table which comprises a table column telescopically variable as to its length, and a foot-arm projecting from said table column. A horizontal arm supports a table top and likewise projects from the table column to the horizontal arm. A supporting stay is coordinated for the support of the free end of the horizontal. The horizontal arm, the foot arm and the table column constitute table members. Means are provided for permitting movement of the supporting stay from a coaxial position relative to one of said members into a supporting position.

Abstract: A tubular central support column provides means for attaching the major load bearing structural components of a rotatable building structure, such that the entire building structure can be lifted and transported by means attached to the top of the central column. This vertical hollow central support column encloses within it a novel utilities-entrance module which provides means for introducing all utilities at one place in a compact centrally located module. Means are also provided for removing effluent.

Abstract: The accounting system is operator-oriented and includes arithmetic and stored program facilities. The system features entry of program instructions through a ''''program by example'''' routine in which the operator enters control (program) information concurrently with the entry of data during conventional typing routines. That is, as the problem is worked, the steps in the operation are stored in program memory. The system is then able to execute the program in a repetitive manner accepting additional keyed-in data, performing calculations, and printing necessary output documents. The system is particularly useful with accounting forms having information arranged in columns. Additional features involve manipulation of column registers, one associated with each column, the branching techniques, decimal point control, determination of true percentages (Percent Equal), use of the Alpha Emit function and the provision of various input and output devices including a magnetic card apparatus.

Abstract: A key-entry system having a plurality of programs selectable by different program keys provided with over-control mechanism operative to allow a change in program only in the first column of a field or prior to the first column and allowing a program change request by depression of a program key to be stored until the last column of a field presently being keyed has been entered.

Abstract: Integral keys including a finger piece, a connecting arm and a support arm are arranged in lines and column rows in a keyboard. The support arm of each key has a guide opening for guiding the connecting arm of the preceding key, and is located under the finger piece of the respective preceding key of the same column row. The supporting arms of all keys of several lines are mounted for angular movement with the finger pieces about parallel shafts.

Abstract: A logic circuit to effect the comparison of a number m of lines in a set of n lines A and energized in any sequence with a number q of energized lines in a set of p lines B. A matrix has a series of n inputs linked to the n row lines and a series of p inputs linked to p column lines. At the nodes of the row and column lines, an AND gate is provided having an inverted output. The inverted output is connected to one input each of two AND gates each having another input supplied by the respective row or column line to provide an output from the row or column line at the nodal point if, and only if there is no coincidence of input. The row and column lines are connected to OR gates and to a comparator, energization of the row or column OR gate, respectively, indicating that the larger number of row or column lines was energized initially; if both OR gates are deenergized, the comparator will indicate equality of numbers of input lines energized.

Abstract: RECALL in a short-term memory (STM) experiment is a function of the meaningfulness and familiarity of the material1, its pronounceability2, frequency3 and the ordered or scrambled arrangement of related items4–6. Similar effects could occur during the scanning of visually presented lists, and we report three experiments where this is examined. In list searching, a subject typically scans down a column of material (list items) for a designated target. The list items are usually letters or words and the targets, single or multiple, are designated beforehand either as one or more letters or as a concept or category an instance of which has to be detected. The item processing time is determined by dividing the search time by the number of items scanned.

Abstract: A coordinate array of fluid-pressure-operated, metallic-contact switching devices are interconnected to provide destructive mark switching operation. Each crosspoint of the array includes two such switching devices with the contacts thereof electrically connected in series. Two sets of row and column fluid channels are arranged such that a fluid pulse on a row or column channel of one set releases at least one switching device at each crosspoint connected to the row or column. Coincident fluid pulses on a row channel and a column column channel of the other set operates both switching devices at a selected crosspoint Destructive mark operation is achieved by timing or pressure differential between the fluid pulses on the two sets of row and column channels.

Abstract: On a six-by-six-inch piece of wood (plywood) construct five rows and five columns using twenty-five nails (finishing nails) so that the distance between all the nails in a row or column is the same. Once the pegboard is constructed it can be used in numerous situations at many different grade levels. Activity cards for a mathematics laboratory setting that make use of the pegboard can easily be made up on the following topics.

Abstract: A method is presented for the analysis of data representing functions of two variables, when the response can be tabulated in a rectangular array. The procedure is based on a partitioning of the row by column interaction effects into a sum of terms, each of which is the product of a row factor by a column factor. the factors in each term are estimated by a method involving the extraction of characteristic roots. The method contains as special cases a number of procedures used for the handling of non- additivity in two way arrays. It is very useful for the fitting of empirical surfaces, but is also applicable to cases in which the data depend on qualitative rather than quantitative factors. Comparisons with other techniques are made and an illustrative example is given.

Abstract: 1. Introduction. We desire to use the inclusion-exclusion formula for determining asymptotic approximations. This object was first achieved for a special problem by P. Erdös and I. Kaplansky [l]. The following indicates the form of the asymptotic estimate we may obtain. Let S be an arbitrary finite set, each element of which may be said to possess \"properties\" from an L-set P of properties {Pu P 2 , • •-, PL}. Let
