Title: Apparatus for selectively clearing a cache store in a processor having segmentation and paging
IPC: G06F12/08
Filed: 1975-03-06
Abstract: 1494365 Selectively clearing a cache store HONEYWELL INFORMATION SYSTEMS Inc 6 March 1975 [10 April 1974] 9417/75 Heading G4A A cache store or high speed buffer store 10 in a central processor (2), Fig. 1 (not shown), of a digital data processing system using segmentation and paging with a backing memory (4) may be selectively cleared if a program changes from one page to another page of memory (a page being smaller in size than the capacity of the cache store), or may be entirely cleared if the program changes segments (larger in size than the capacity of the cache store) or when an external interrupt is signalled indicating that a new program is to be initiated. The cache store 10 is divided into four levels A-D each of 128 blocks, and is coupled to an associative tag directory 28 having four columns corresponding to the levels of the cache store and 128 rows corresponding to the number of blocks in each level of the cache store. The tag directory 28 holds the absolute addresses of data in the backing memory (4), the locations of tag directory 28 being accessed by address signals ZC09-15 for row selection, and by means of a level selector circuit 25 for level or column selection. Addresses AL00-08 requested by the central processor are compared in a comparator circuit 29 with read-out address signals M1-M4 from the tag directory; if a match is found a MATCH signal causes interruption of an initiated accessing routine of the backing memory (4) and an accessing of the cache store instead. Writing into the four levels of an addressed row of the tag directory 28 is on a first-in, first-out basis controlled by a two-bit binary counter (94), Fig. 6(a) (not shown) coupled to the level selector circuit 25. Addresses for the cache store 10 are obtained by concatenating each of the read-out absolute address signals M1-M4 from the tag directory with onebit signals CA and CB obtained from an encoder 29b coupled to the outputs of comparator circuit 29. Each block of the tag directory 28 has associated therewith a storage location in an integrated circuit memory chip (43), Fig. 6b (not shown) which stores a full/empty status indicator bit corresponding to that block. Clearing of the blocks of the cache store is effected by resetting these status indicator bits. If the whole cache store is to be cleared, a pulse generator (65), Fig. 7 (not shown) transmits pulses to a counter (66) which generates sequential address signals for sequentially clearing the rows of the tag directory. Selective reloading of the cache store is also possible by means of a circuit which instructs the counter (94) to omit the addresses of those blocks which are full, only the empty blocks being reloaded.

Title: Improvements in or relating to gas meters
IPC: G01F3/30
Filed: 1924-04-14
Abstract: 214,622. Compagnie pour la Fabrication des Compteurs et MatÚriel d'Usines Ó Gaz. April 21,1923, [Convention date]. Gas meters.-In order to obtain a constant level in the measuring chambers of the drum of a wet gas-meter, the water surfaces subjected respectively to the inlet and outlet gas pressures are of such areas that the fall of level in the inlet chamber due to the pressure difference caused by the passage of the gas from the inlet chamber to the measuring chambers displaces the same quantity of water as is required to effect the rise of level in the space subject to the outlet pressure due tothe pressure difference required to revolve the drum. In the construction shown, the measuring drum 2 is made of smaller width than usual, so that the gas inlet chamber may be of normal size. The levels subject to the different pressures are indicated by the lines a-a, b-b, c-c. Owing to the small width of the drum the overflow tube can be arranged at the centre of the intersection of the plane of the water level with the meter walls and a much greater inclination of the meter than usual is required before gas can pass through the meter unregistered. An additional advantage is that the meter casing may be made from shallow, pressed or cast members comprising a cover and either one or two lower members. The joint 8 for the cover is made above the water level so that soldering will not affect any protective coating in the area in contact with the water.

In a radio receiver with preset tuning, which may be remote controlled, diodes are used as switches. The arrangement may also be used in transmitters. A transistor oscillator (Fig. 1, not shown), used in a receiver or transmitter is backcoupled over transformer 30 the secondary winding of which is timed to one desired frequency by means of a capacitor 32. Across this capacitor are connected further capacitors 34, 38, 42, 60, 70, 76 in series with Zener diodes 36, 40, 44, 62, 72, 78 respectively, all of which are normally non-conductive. The Zener diodes 36, 40, 44 are all poled in the one direction and are connected over resistors 54, 56, 58 respectively to a diode 52 which is connected to a, remote frequency-selection switch via resistor 50. The Zener diodes 62, 72, 78 are all poled in the opposite direction and are connected via resistors 64, 74, 80 respectively to diode 68 which is connected to the remote switch via resistor 66. By suitable selection of different breakdown voltages for the Zener diodes and arranging for the remote control switch to pick up appropriate bias voltages, the Zener diodes can be made to break down in turn, successively switching the various capacitors into the circuit.

Abstract: 1427455 Automatic control of temperature CONTROLS CO OF AMERICA 5 March 1974 [16 March 1973 15 Jan 1974] 9802/74 Heading G3R [Also in Divisions F2 and F4] In a refrigeration system comprising a compressor 10, condenser 14, expansion valve 18 and evaporator 22, the temperature of the refrigerated space is sensed by a thermistor 30 connected in one arm of a bridge circuit, the arm being adjustable e.g. by a resistor 36 to pre-set the desired temperature, and a signal from the bridge circuit is used to control a valve 26 between the compressor and the evaporator, to control the evaporator pressure and thus the space temperature. As shown the valve 26 is normally open (during temperature pulldown) and operates to reduce the flow from the evaporator to the compressor when the set temperature is reached. The valve may alternatively be a normally closed valve (126), Fig. 4 (not shown) operative to by-pass hot refrigerant back from the compressor outlet to the evaporator. The valve 26 is a sleeve valve in which a bi-metal stack (76) Fig. 2 (not shown) operates the sleeve (86) against the force of a spring (88) when heated by a heater 74 receiving the amplified control signal. The system may be applied to the control of an air-curtain type refrigerated display case (98), Fig. 5 (not shown), the thermistor 30 being in the air-curtain and the bridge arm containing a second resistor (104) which can be shunted by a switch (106) for defrosting or at shop closing time.

During the closing movement of the door the fluid passes through ports 51 in the spindle 14 until this path is closed by 58, then it passes through ports 53a, 55, 53b in the spindle 14 until the door is closed. Ports 51 are controlled by a block 48 vertically adjustable by a stem 44.

Title: A programmable controller with debugging capability
Inventor: WARD DEREK
IPC: G05B19/05
Filed: 1996-07-11
Abstract: A programmed controller (10) controls a machine or process by emulating state diagrams and executing an applications program having a number of blocks (50,52) of statements each block corresponding to a step in the operation of the machine or process, each state diagram being represented by a program loop. Each loop has only one state (24,26,28) active at any one time and has variables such as pointers (68) in each of which is stored the address of an active block. When transition conditions of a state in a block are satisfied, a decision point (266) is reached, that state (24,26,28) is deactivated and another state (24,26,28) activated in a desired sequence with consequent required operation of the machine or process. The transitions (30,32,34,36,54,56,58) that occur with regard to which states (24,26,28) are active and the order in which they occur are recorded and later retrieved and presented for example for debugging uses to a user.
