In order to obtain visible information as to the most economical paths to be followed by elongated members joining certain points, such as pipes connecting units in a chemical or fluid handling plant, within the limits of certain desired conditions, information as to the position and dimensions of the units and the position of the points thereof where the pipes are to be connected, together with information as to the desired limitations, is fed into the computer, the output data of which, representing the positions of all the points along the paths of the pipes, is used, immediately or after storage in the computer memory or elsewhere, to operate a drawing mechanism to produce a drawing of the completed unit and pipe assembly as viewed from any desired direction. Firstly, a plot plan, i.e. an original drawing to scale, of the units is made, from which can be made a table giving the X, Y and Z co-ordinates, measured from a selected origin, of the mid-points of each unit, together with the dimensions of each unit and a statement as to which axis its longest dimension lies in. The tabulated data is transposed by the computer into a series of algorithmic members representing the designation and disposition of each unit, together with its maximum and minimum co-ordinates on each of the three axes. Any desired limitations are programmed into the computer, e.g. prohibition of pipes entering certain areas, minimum distance between pipes, pipes to lie parallel to one or more of the axes, number of bends in the pipes to be a minimum, &c. The output data may be magnetically impressed or punched on tape, or in punch-card form, and a typewritten or other tabulated form also produced. The data is utilized to control an X-Y plotting machine to produce drawings showing the pipe system as viewed from any desired direction.

Abstract: 1515533 Log-periodic array C & S ANTENNAS Ltd 2 Aug 1976 [20 Aug 1975] 34646/75 Heading H4A An aerial array comprises a plurality of broadband active aerial elements of substantially equal impedance and linearly arranged with their spacings along the array being in a logarithmic progression, the elements being connected to respective filters which pass higher frequencies where the elements are more closely spaced and lower frequencies where the elements are more widely spaced. In the Fig. 1 embodiment the elements are loops 12, coupled via amplifiers 14, individual feeders 15 and filters 16 to a common feeder 20 with a terminating load 26. If the required loop spacing at the end of the array associated with the higher frequencies is such that the loops would overlap, the loops may be arranged in two staggered rows. Amplifiers 14 may be reversed, as at A, if the array is to be used for transmission. As the element spacings progressively increase, so the lengths of feeders 15 may decrease. Each loop 12 comprises, Fig. 5, a pair of aluminium strips bridged at intervals and embedded in glass-reinforced plastics, the top of the loop being divided and bridged by a resistor to increase the impedance locally, resulting in a cardioid directional pattern for an individual loop. The array as a whole acts as an end-fire array. In a modification (Fig. 6, not shown), filters 16 are connected by individual feeders to a receiver, rather than by common feeder 20. Several arrays may be radially oriented in a star formation, the signals of two or three arrays at a time being combined to provide e.g. 16 beam directions from 8 arrays (Figs. 7 and 8, not shown). Broad-band whip or dipole elements may be used instead of loops.
