Abstract: 758,930. Cathode-ray tubes. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Sept. 7, 1953 [Sept. 10, 1952], No. 24679/53. Class 39 (1). [Also in Group XXXV] . In a deflecting magnet of the kind in which polepieces 3, 4 mounted on the ends of permanent or electromagnet 13 at the side of the tube 1, and project therefrom so as to embrace the tube, the polepieces are made so that their reluctance decreases with distance from the magnet. This reduces deflection astigmatism by increasing the proportion of the flux which can reach to the ends of the polepieces. The decrease in reluctance may be achieved by increasing the width, Fig. 2, or depth, Fig. 4, of the polepieces, or by making them of material of progressively increasing permeability for example, ferrites. The change of reluctance may begin right from the magnet or may only begin half-way along the polepiece.

Abstract: 1536043 Data processing HONEYWELL INFORMATION SYSTEMS Inc 17 June 1976 [19 June 1975] 25122/76 Heading G4A In a data processing system, data (in the form of sets of database records, each set having an associated set descriptor (Fig. 19a, not shown), an owner database record and member database record(s) (Fig. 15b, not shown), the records containing pointer sequences (Figs. 15c, 15d, not shown) to other records and each record having an associated record descriptor (Fig. 19b, not shown)) is stored in segments in main memory, the relationship between a set and a member being determined by accessing the set descriptor, using this to access a database record, the pointer sequence in which is then examined to determine the relationship between the record and the set. "Test if record is empty" instruction.-The set descriptor (Fig. 19a, not shown) indicated by the address syllable (AS, Figs. 20b-20e, not shown) of the instruction stored in a register (2302, Fig. 23, not shown) is fetched and its displacement used in conjunction with the contents of the base register (BR) indicated by the instruction to access pointer sequence (e.g. 1513, Fig. 15b, not shown) of an owner record. The second bit of the pointer sequence is then tested to see if the record is a member of a set and if it is, the first bit is tested to determine whether the set has any member records and to set a condition code in a status register to 0 or 1. In a similar way a "test if member is inserted" instruction controls the setting of the condition code in response to the testing of the first bit of a pointer sequence of an accessed owner or member record. "Location of a database page" instruction (Fig. 18, not shown).-The area page number of the descriptor relating to the required page is stored in a register (1582). An integrated access control pointer IAC (Fig. 16c, not shown) is accessed and its G number and displacement D is used to fetch a page descriptor (Fig. 16b, not shown). Comparator (1878) compares its area page number with the contents of the register (1852), equality indicating completion of the operation. Otherwise the displacement for the next descriptor portion is used to access a further page descriptor for comparison. This process is repeated until either the required page is found or until all the descriptors have been accessed, indicated by the contents of a first pointer register (1870) and the next descriptor portion being identical. A paging exception then occurs.
