Title: Data Processing System including a Cache Store
IPC: G06F12/08
Filed: 1978-11-24
Abstract: A data processing system includes a main memory system, a high speed buffer cache store, a central processor unit (CPU) and an Input/Output processor (IOP) all connected to a system bus. Apparatus in the cache store reads all information on the system bus into a first in, first out buffer comprising a plurality of registers, a write address counter, a read address counter and a means for selectively processing the information. The cache store is word oriented and further comprises a directory, a data buffer and associated control logic. The CPU requests data words by sending a main memory address of the requested data word to the cache store. If the cache store does not have the requested data word apparatus in the cache store requests the data word from the main memory system, and in addition, the apparatus requests additional data words from consecutively higher addresses. If the main memory system is busy, the cache store repetitively supplies the requested address to the main memory system, and has apparatus to request fewer words. The cache store is organized in levels. Data from a particular portion of main memory is transferred to these levels on a first in-first out basis. Apparatus in the form of round robin logic circuitry makes the first in-first out level selection. Apparatus also exists for resetting the round robin count during the initialization procedure. Apparatus in the cache store monitors each communication between system units to determine if it is a communication from a system unit to the main memory system which will update a word location in main memory. If that word location is also stored in the cache store then the word location in the cache store will be updated in addition to the word location in main memory.

Title: Torque Measuring System
IPC: G01L3/10
Filed: 1981-08-19
Abstract: A microprocessor-based torque measuring system for a twin-engine- aircraft gas turbine engine installation comprises respective inductive sensors 16, 18 for each engine. The sensors are positioned to co-operate with respective pairs of toothed wheels 55, 56, which are secured to axially spaced points on the engine shaft whose torque is to be measured and have interlaced teeth 57, 58 whose spacing varies with torque. Each sensor produces a torque signal which, after suitable pulse shaping, has a mark-space ratio representative of torque. The respective durations of the mark and space periods of the signal are measured digitally by counting at counters 180 or 182 clock pulses during successive groups of mark periods and space periods. The accumulated counts are then subjected to recursive digital filtering by a microprocessor 170, in accordance with a predetermined function approximating the response of a low pass or, more specifically, a second order Butterworth filter, said to increase resolution and enhance noise rejection. The microprocessor then calculates the torque for each engine, using the appropriate filtered counts together with digital signals respectively representative of the temperature, stiffness and zero-torque twist of the respective shaft. <IMAGE>

Title: Drive line for transmitting power from a tractor to an implement pulled by the tractor
Inventor: LAMSFUSS UWE
IPC: A01B71/06
Filed: 1985-08-12
Abstract: A drive line (26) for an implement (14) attachable to a tractor (10) includes two double cross bearing universal joints (32 and 34). During turns between passes over crop the power delivered by the line must turn through a working angle as large as 90 DEG . but for such a tight turn each joint turns the power through two angles of only 22 1/2 DEG  thus enabing full power to be used between passes without undue wear. The implement (14) is attached to lower links (18) of the tractor (10) by way of a yoke (16) which in turn is connected to a drawbar (12) of the implement (14) via a pair of channel-shaped supports (20, 22) rigid with, and at right angles to, one another. One support (20) receives the forward end of the drawbar (12) in its channel and is connected thereto by a vertical pivot pin (21). The other support (22) similarly receives the yoke (16) to which it is connected by a horizontal pivot pin (23). There is thus provided a drive and an arrangement for attaching the implement (14) to the tractor (10) which permits tight turns to be made efficiently.

Title: Improvements in encoding magnetic cards
Inventor: YAMASHITA TOSHIHIKO
IPC: G06K19/06
Filed: 1986-01-15
Abstract: A system and apparatus for encoding magnetic information on a magnetisable substrate where the substrate is liable to be moved erratically, e.g. manually, past a magnetic head. Two parallel tracks are provided on the substrate and the first is encoded with binary information conventionally with shorter spaces between change of field representing one binary digit and longer spaces representing the other digit. The other track is encoded using changes in field on the first track as a timing reference such that any change of field on the second track substantially coincides with a change of field on the first track and one digit of the binary pair is represented by no change in field as the field changes on the first track whilst the other binary digit is represented by a change of field coincidentally with a change of field on the first track. The system and apparatus are eminently suited for use in parking meters where a power source to drive a card consistently past a reading head is not available.
