Abstract: ABSTRACT OF THE DISCLOSURE      A spring coil has an open-ended terminal convolution which is connected to the body of the coil through a gradient arm.  The gradient arm can be readily varied in length in manufacture to alter the compression and thereby the firmness of the spring coil.  One or more offset portions can further be provided on the terminal convolution.  Such offset portions are advantageously formed with a major straight part which is outwardly spaced from minor straight parts.  This provides a three point engagement for the offset portion when connected to a border wire with a border wire helical spring. The springs making up an innerspring assembly are arranged in rows and columns.  The offset portions of adjacent springs are overlapped in rows and are joined together with cross-helical springs that extend along columns and encircle the overlapped portions.  The offset por-tions of the spring coils have inside and outside shoulders adjacent their ends, and the pitch of the cross-helicals is advantageously chosen so that a cross-helical simultaneously engages the outside shoulders of one of a pair of overlapped offset portions to hold the spring coil against rotation.  The cross-helical prefer-ably also catches the inside shoulders of the other overlapped portion to additionally hold that spring coil against rotation.  A mattress innerspring is further disclosed with the rows arranged across the width of the mattress and the columns extending along its length. Cross- helicals can also be used across the width of the mattress in addition to those extending along the longitudinal columns. The width cross-helicals can be used for extra firmness for the entire mattress, or for selected areas, such as the middle third.  One embodiment further shows the use of such orthogonal cross-helicals with overlapping spring coil rows.

Abstract: In a pay phone system, a plurality of pay phone apparatuses (40) and a remote central computer (54) are included. The pay phone apparatuses (40) communicate with the central computer (54) through telephone lines and further via a telephone central exchange (52). The pay phone apparatuses (40) are operated by means of magnetic cards (55, 56 or 57) or optionally by means of coins. Each card (55, 56 or 57) includes information or data readable from the card and identifying the card and further representing an amount corresponding to an allowable telephone call duration. The pay phone system is operated in the following manner: The card (55, 56 or 57) is received in a card receiving slot (42) in the apparatus (40) and the data of the card are read from the card and stored in a first storage means of the pay phone apparatus. The first storage means of the pay phone apparatus is addressable from the remote central computer (54) for transferring data stored in the first storage means to the remote central computer. In a second storage means of the pay phone apparatus, data transferred from the remote central computer (54) are stored. In a comparator means of the pay phone apparatus, the data read from the card and stored in the first storage means are compared to the data stored in the second storage means. By the comparison, the card is identified as a legal card or as an illegal card identified by the data of the second storage means. In case the card is identified as an illegal card, the card is rejected from the pay phone apparatus. In case the card is identified as a legal card, a telephone call is permitted. In a debiting means, an amount corresponding to the duration of the telephone call is determined and in a subtraction means of the pay phone apparatus, the amount is subtracted from the data stored in the first storage means representing the amount corresponding to an allowable telephone call duration, and a reduced amount is generated and stored in the first storage means. When the amount determined by the debiting means exceeds the amount corresponding to the allowable telephone duration, the telephone call is interrupted. At the end of the telephone call, the data stored in the first storage means are written in the card by means of a writing means of the pay phone apparatus and identifies the card and further represents the reduced amount corresponding to an allowable telephone call duration. Periodically, the remote central computer (54) addresses the first storage means of the individual pay phone apparatus and transfers the data stored therein to the remote central computer for processing therein. On the basis of the data transferred fromthe first storage means of the individual pay phone apparatuses, the remote central computer updates the data of the second storage means of the individual pay phone apparatus.
