Abstract: CONTROL SYSTEM FOR FLEXIBLE DISK FILE              Abstract of the Disclosure Control information for a flexible magnetic disk storage assembly is recorded on the periphery of the disk in a region not used for recording data.  The control information is read through the protective cover or envelope which encloses the disk by means of a magnetic transducer such as a four track audio cassette head which bears against the envelope.  By recording index and sector pulses as part of the control information, hard sectoring can be inexpensively and accurately achieved.  A recorded fixed frequency control signal can be read and used as part of the feedback loop in a phase locked oscillator used to control a d.c. motor driving the spindle.  The control information can also include servo tracks which assist in registering the data transducer directly over data tracks on media which has changed its dimensions.

Each module has a generally planar body with edge faces, a top face and a bottom.  Each edge face has a plurality of outwardly projecting fingers designed to provide a snap-together lateral interlock between fingers of adjacent modules while permitting hinging or rotation between modules on an axis parallel to the side face.  Projecting upwardly from each top face is at least one hub consisting of a set of V-shaped fins equally spaced in a circular configuration.  The bottom of each module has a recess or socket directly behind each V-fin hub and each bottom recess is shaped such that it can receive and snuggly retain a set of V-fins of another module.  With this design the modules can be joined edge to edge, top face-to-bottom face and top face-to top face.

Abstract: ABSTRACT OF THE DISCLOSURE            A REINFORCING ROD HOLDER FOR USE IN CONNECTION-TYPE          CONCRETING OPERATIONS AND A METHOD OF PRODUCING SAME    The reinforcing rod holder includes a hollow body (1) in which the downwardly bent reinforcing rods (2) are inserted in such a manner that their U-shaped anchoring portion protrude.      The free ends (3 and 4) of the reinforcing rods are disposed entirely in the hollow body, together with the bend portion.   To permit insertion of the anchoring portions, the hollow body is provided with apertures (5), and holes (6) having a diameter which is approximately identical to the diameter of the reinforcing rods  are provided at the two ends of such apertures (5), while the central portion of the apertures is sealed by two overlapping flaps (7).          The hollow body is further provided with mounting or support ribs (8) at the apertures (5) and two spacer ribs (9 and 10) between the last three apertures (5) in order to serve as support faces for the ends of the reinforcing rods.    The hollow body, containing the reinforcing rods, is filled with expanded plastics material.    A reinforcing rod holder of this type is used in connection-type concreting operations and is advantageous in that, on the one hand, the portions of the reinforcing rods not embedded in concrete are packed in expanded plastics material and therefore cannot rust and, on the other hand, the expanded plastics material can be completely and conveniently removed by extracting the hollow body when the connection-type concreting operation is being carried out.  In addition, the hollow body actually serves as a mould, thereby ensuring that the reinforcing rod holder is produced rationally and cheaply.
