Title: Improvements in or relating to a method and apparatus for producing duplicate records from a master magnetic recording
Inventor: CAMRAS MARVIN
IPC: G11B5/86
Filed: 1953-03-10
Abstract: 742,666. Duplicating magnetic records. ARMOUR RESEARCH FOUNDATION OF 'ILLINOIS INSTITUTE OF TECHNOLOGY. March 10, 1953, No. 6559/53. Class 40(2) A magnetic master record is duplicated by passing it with a copy record through a magnetic' transfer field whilst resiliently pressing the records together. In the modification shown in Fig. 1, the pressing members 13, 17 are positioned within the windings of a solenoid 14. The copy 11a may either be saturated by a D.C. field or demagnetized by an A.C. field prior to duplication. The solenoid may be supplied with either D.C. or A.C. The copy may be " aged " by subjecting it to an A.C. field- In a modification, Fig. 4, the copy and master records are pressed against a magnet 21 having, a non-magnetic gap 22 and coils 23 which may be supplied with A.C. or D.C. The magnet may be of solid orlaminated construction and the non-magnetic gap may be arranged obliquely to the longitudinal axis of the record (see Fig. 6, not shown). In a further modification, Fig. 5, the magnet may be formed as shown and a plate 28 shaped to guide the records may be placed between the records and the magnet. The edges of the upper corners of the non-magnetic gap may be rounded. The master record may be made from a magnetic powder on a backing such as metal, nylon or cellulose acetate. It is stated that the coating of powder may be made thicker than usual to improve the low frequency response of the master record. Alternatively the master record may be made of an alloy comprising copper, cobalt and nickel and may be about .002 inches thick. This type of record may be coated with a laquer to prevent magnetic leakage, when the record is coiled on itself. Before using the master record, it may be subjected to an A.C. field which helps to prevent the copy record from being retransferred to the master record, if the records slip relatively to each other. Specific figures are given of the desired magnetic properties of the records.

[Also in Division G5] A legend is, or characters forming a legend are each, formed from one or more polymethyl methacrylate Fresnel lenses, each such lens having illuminating means in its focal plane. Fig. 1 shows a letter D, cut from a complete lens (Fig. 3, not shown, is a cross-section) and mounted behind a face panel 2 (Fig. 2). Alternatively, parts of a whole lens may be obscured from view by a stencil. The lens elements are cemented to the rear of the panel 2, and a second transparent or translucent panel may be placed behind, the intervening space being sealed to protect the lens elements. The panel around the legend may be painted and the panel over the legend tinted to reduce reflection, so that the sign is legible only when lamp 5 is lit. Each character may have a lamp, or a common strip lamp may illuminate a row of characters. The lens elements may be coloured. Diffusing screen 6 may be coloured or additional coloured screens may be fitted, for example a screen on each side of a lens axis, in front of a diffusing screen, will make the lens element appear to change colour as an observer moves past. The function of the Fresnel lens element is that light is concentrated in particular areas, the sign being intended for warning or guiding aerial, rail and road traffic. The emitted beam may be made divergent by proper design of lens angles, or divergence in one plane only may be achieved using ribs on the backs of the lens elements. A coloured-sector disc may revolve behind characters to give changing colour effects.
