Title: Data processing systems
IPC: G06F12/08
Filed: 1974-05-09
Abstract: 1468929 Accessing memories HONEYWELL INFORMATION SYSTEMS Inc 9 May 1974 [31 Aug 1973] 20632/74 Heading G4A A data processing system includes a main memory (not shown) and a first access cache store 10 (Fig. 1), the latter having a tag directory 28 storing in each location an absolute address in main memory and an address for the cache store of information held therein, part (ZC00-ZC09) of an input address being added to the contents of the base address register 18 to form the absolute address (AA00-AA09) and part (ZC10-ZC15) being used to access the tag directory, a match between the generated absolute address and the stored absolute address resulting in a "match" signal from comparator 29 so that the cache store is accessed, the signal from an interrupt generator 16 permitting access to the main store then being inhibited. As described the cache store comprises chips storing data in four sets of blocks A0-A63, B0-B63, C0-C63, D0-D63, the tag directory having 64 rows each of four blocks, the contents of each block being compared in four comparator circuits in the comparator 29 to generate a two bit signal CA, CB representing the required block which is used together with the address bits (ZC10-ZC15) to address the selected block, further bits (ZC16-ZC17) selecting one of four words in that block. The arrangement is such that since the tag directory is addressed directly by the bits ZC10-ZC15, in the event of the data being in the cache store a match signal is derived from the comparator 29 before the interrupt generator generates the signal INT to access main memory with a computed address and transfer the requested data via switch 12 to the cache store. If the cache store is full data is displaced on a first-in first-out basis.

Title: Automatic aerodynamic stabiliser for aircraft
IPC: B64C1/00
Filed: 1933-07-24
Abstract: 422,493. Stabilizing aircraft automatically. BEMBERG, O. E., 28, Rue Emile Menier, Paris. July 24, 1933. Nos. 20784 and 20785. Convention dates, July 22, 1933 and July 10, 1933. [Class 4] An aeroplane is stabilized laterally and in some cases also longitudinally by a device resembling a small aeroplane universally mounted above the machine, upon a lever upon a longitudinal shaft fixed to the aeroplane, relative movements of the lever being utilized to move the ailerons. Servo devices may be employed, and the longitudinal control may be acted upon by a device which dives the machine, should the engine fail or the machine be tilted upwards too sharply. A series of radiating planes g is freely mounted on a shaft f supported from a bent bar d having a tail fin h comprising freely pivoted radiating planes. The bar d is mounted on a cardan joint c carried by a bell-crank lever m, pivoted to the machine at o and connected by links to the usual control lever. The angular movements of both lever and the device are limited by short cables. Fig. 5 shows the device adapted to control the lateral and longitudinal stabiity through a servo system. The bar d is mounted on a ball joint c on a lever 6 which can move about a pivot 5 on a fixed transverse support 4, and a link 31 transmits relative pitching movements of the bar d through the linkage shown to a vane 20 pivoted in a frame 21 turnable about a shaft 22. The air pressure on the vane is transmitted through linkage 23, 24, 25 to the control lever r. A vane 21 on the frame helps to restore the parts to their normal position. Relative lateral movements of the lever 6 are transmitted through linkage 18, 17, 16 to a similar servo device to act on the aileron control. Should the slip stream fail or the craft lose speed due to excessive tilting a spring-loaded pressure surface 37, Fig. 6, moves forward and deflects a lever 39 to tilt a servo-surface 45 to cause a dive by acting on the control lever r. Springs 49, 50 tend to keep the parts in their normal position, and when the machine is on the ground a shoe 53 keeps the surface 37 in its rearward position. The Specification as open to inspection under Sect. 91 comprises also a similar device mounted upon a joint c on a bracket b, Fig. 3 (Cancelled). A spindle i in alignment with the joint c is carried by the bar d and has a plane j freely pivoted on the spindle. The plane is connected at the points l to cables connected to the ailerons. A rest n supports the bar d when the machine is at rest. A pair of dihedrally mounted planes, or a cylinder may replace the radiating planes g. This subject-matter does not appear in the Specification as accepted.
