Title: Improvements in thin bands, particularly applicable for tipping cigarettes
IPC: A24C5/56
Filed: 1929-08-20
Abstract: 337,501. Chemische Fabrik von Heyden Akt.-Ges. Feb. 15, 1929, [Convention date]. Cigarettes.-Thin bands particularly adapted for tipping cigarettes consist of two continuous layers of cellulose esters or ethers, of which one contains a pigmentary substance such as metal powder, while the other contains a material such as powdered magnesia, lithopone, powdered cellulose, or cork, which enhances its affinity for adhesives. The layers may contain the same or a different cellulose derivative., for example, a layer of acetyl cellulose with bronze powder may be cast on a layer of ethyl cellulose and cellulose dust, or a layer of benzyl cellulose containing a substance enhancing the affinity for adhesives may be cast on a layer of nitrocellulose containing a pigment. The composition of the two layers is chosen so that they dry at approximately the same rate so as to minimise or avoid curling, but in making cigarette tips a tendency of the film to roll up is often an advantage. Specifications 269,194 and 288,592 are referred to.

Title: Improvements in or relating to magnetic storage systems
IPC: G11C11/06
Filed: 1958-08-08
Abstract: 841,669. Circuits employing bi-stable magnetic elements. PHILIPS ELECTRICAL INDUSTRIES Ltd. Aug. 8, 1958 [Aug. 13, 1957],No. 25529/58. Class 40 (9). A magnetic core having a rectangular hysteresis loop stores a binary zero when a negative pulse NS is applied of sufficient amplitude to drive the core flux to the maximum remanent state N, and stores a binary one when acted on by a positive pulse PS of lesser amplitude, the positive pulse amplitude being insufficient to drive the core flux into positive saturation so that it stabilizes at an intermediate remanent point P1. The remanent polarity of the core is detected non-destructively by applying an alternating voltage UW of small amplitude, and since the minor hysteresis loops about the remanent points N and P1 have different slopes, an effective alternating voltage is induced in an output winding only when the core stores a binary one.
