Title: Improvements in or relating to magnetic storage equipment
Inventor: BAKER GEORGE THOMAS
IPC: G11B5/02
Filed: 1955-07-13
Abstract: 818,773. Electric digital-data-storage apparatus. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. July 2, 1956 [July 13, 1955], No. 20329/55. Class 106 (1). A scanning control arrangement for a magnetic drum storage device effects scanning of a storage track under the control of a series of markings on a control track whose positions are successively changed so that all the elements of the storage track are scanned. As shown a magnetic drum, Fig. 1, stores a plurality of words in each track all having the same number of binary digits and has a control track C with a plurality of markings, the number of markings being equal to the number of digits in one of the stored words. The relation between the total number T of element positions on each storage track and the number N of positions embraced by the heads CR, CW at the control track C is such that T and N have no common factor, so that since whenever the read head CR encounters a marking in the form of a " 1 " the head CW writes a " 1 " followed by a " 0," the markings are successively shifted round the control track by one space at a time and every storage track position is scanned. An output from the regeneration circuit extends over a lead SP to indicate when a store position on a storage track of the drum is to be scanned. A marking track M having a single marking may be provided to serve to control transfer of scanning from one storage track to another, As shown in Fig. 2, a drum with a circumferential total of 997 storage positions and adapted to store in each track a total of 166 words of 6 digits is scanned in the sequence indicated by the numbers 1 to 997 by providing a control track having six markings, the track marking position corresponding to position 997, and the first positions of each storage word being in sector 1. If the numerical relation between T and N is such that the first elements of each stored word are not adjacent (as in Fig. 3, not shown), there may be provided a synchronizing track S on the drum having a plurality of markings equal in number to the number of words stored and disposed round the drum so as to correspond to the first elements of each word, this track being used to indicate correct resumption if scanning is interrupted. The distance between successive markings on the control track may be altered by switching, means in the regeneration circuit adapted to cause the head CW to write a plurality of " O's " before writing a " 1 " or by varying the spacing between the heads CR and CW, or by providing a plurality of different heads which may be selectively utilized.

Abstract: 700,947. Reinforced concrete. LAING & SON, Ltd., J. Oct. 23, 1952 [Aug. 29, 1951], No. 20344/51. Class 20 (4) In a process for making prestressed concrete beams, the contamination with oil from the mould sides of the reinforcing wires is prevented by securing the wires between tensioning members located above and beyond the ends of the beam mould, partly tensioning the wires to prevent sagging and then lowering the tensioning members in unison to bring the wires to their correct positions within the mould. The apparatus consists of a mould box A containing a number of parallel channel-like moulds. Beyond each end of the mould box is positioned a pair of uprights F each having an arm G from which is suspended a yoke I by means of threaded rods H. The ends of reinforcing wires D are secured to the yokes and are partly tensioned by rams N which bear against uprights O so that the wires do not sag. Templates B, Fig. 4, are inserted into the mould to divide it into the required lengths and the yokes lowered in unison by rotation of the shafts H, the wires entering the mould and being guided by the vertical slots C in the templates. Plates K with transverse slots L are then placed against each template to secure the wires against vertical displacement and the wires brought to their final tension by the rams N. The moulds are then filled with concrete. After the concrete has hardened the wires D are cut, the sides of the mould are removed and the finished beams lifted out.
