Patent GB-1432848-A (GB)
Title: Computer memory systems
IPC: G06F12/08
Filed: 1973-08-08
Abstract: 1432848 Computer systems HONEYWELL INFORMATION SYSTEMS Inc 8 Aug 1973 [5 Oct 1972] 37694/73 Heading G4A A computer system includes a central processor unit 306 (Fig. 3), the high speed buffer store 304 and a main memory 301, the buffer store being operable in a plurality of multiple length byte group modes. In operation the CPU supplies an address comprising bits 8-29 for the buffer 304 to address unit 307. Bits 20-26 are used to address directory module 305, bits 11-19 being compared with the data in upper and lower row fields in the directory in a comparator 308, a successful hit indicating that the required information is in either the upper 304U or lower 304L module of the buffer (each module being further divided into upper and lower banks). Bits 20-29 are utilized to address the modules, 4 bytes being read out in a read operation and 8 bytes being written in, in a write operation. In the embodiment in which the buffer store is of two modules of 128 columns, each column containing one block of 32 bytes, if no hit occurs the information is retrieved from main memory 301 comprising four modules 301A-301D, 8 bytes being loaded into the buffer store and 4 bytes being delivered to the CPU. The address is then incremented and another 8 bytes are delivered to the buffer store. This process is repeated twice making a total of four accesses. If a successful hit is made, validity bits are examined to check that the data has not been altered or is not in error. An activity field indicates the least recently used upper or lower field so that a write location may be selected when no hit occurs. The system may operate in a 128Î2Î16 mode with a buffer store of half the above size (Fig. 5, not shown). In this case each column stores only half a block, i.e. 16 bytes so that only two accesses to either module are made since only half a block of information is read from or written into a column. In a further mode, the 256Î2Î16 mode (Fig. 6, not shown), each column holds one 8 byte word, 16 bytes being loaded into the buffer (in two accesses) when a no hit situation necessitates addressing the main memory. In a further mode, the 128 x 2 x 32/16 (Fig. 7, not shown) either a full block or a half block may be referenced from a column. Mask fields may be developed if for example only one byte of a word is to be written. The mode selection circuitry is given in Fig. 8E (not shown).

Title: Improvements in process of making cellulose acetate
IPC: C08B3/06
Filed: 1929-12-10
Abstract: In the manufacture of cellulose esters, the cellulosic material is subjected to the action of a solution of nitrogen dioxide, preferably a saturated solution in acetic acid or other lower fatty acid, prior to esterification.  In an example, cotton linters are treated with a saturated acetic acid solution of nitrogen dioxide for 10-20 hours at 20-30 DEG  C., after which the solution is filtered and the treated cotton is dehydrated by means of acetic acid and acetylated, e.g. in a bath containing acetic anhydride, ethylene dichloride and a small quantity of phosphoric and sulphuric acid.

A protractor calibrated in terms of standard deviation is used in combination with a graph drawn on Arithmetical Probability paper and on which are plotted at least two points each representing a value of the mass per unit length of a cigarette rod against the percentage frequency with which that value was exceeded in a sample represented by the point, to read off the standard deviation of the mass per unit length. The protractor is calibrated so that the percentage standard deviation of the information represented by the line joining these points may be read directly by measuring the slope of the line. In a modification a further arc of dots on the protractor is used to show a predetermined percentage tolerance of the standard deviation calibrations. Specification 929,337 is referred to.

Title: Process for automatically controlling the operation of a travelling grate and an associated cooler

Filed: 1973-08-15
Abstract: 1385624 Controlling a travelling grate and associated cooler METALLGESELLSCHAFT AG 15 Aug 1973 [13 Sept 1972] 38605/73 Heading F4B A process for automatically controlling the operation of a travelling grate for sintering and firing solid material and an associated cooler in which the hot material discharged from the grate is cooled by passing cooling gases through the material comprises measuring the temperature of the cooling gases emerging from the material during its path of travel through the first third or half of the cooler and feeding the signal representing the measured temperature to an automatic control system. A deviation of the measured temperature from a predetermined value either alters the volume rate of the cooling gases supplied to the cooler after a predetermined dead time or both causes a reduction of the rate at which the hot material is discharged by the grate and also increases the cooling time if the temperature deviation exists for a longer dead time, e.g. from 5 to 15 minutes. The temperature of the cooled material discharged from the cooler is measured and operation of the grate and discharge from the cooler are shut down when the temperature exceeds a predetermined upper limit.

In a vacuum operated refuse collecting vehicle one or more suction nozzles communicate with an airtight receptacle at such a point relative to an outlet from the receptacle communicating with means for generating a vacuum in the receptacle that indrawn air flows up one side of the receptacle, around a curved upper part and down the other side before passing out through the outlet. As shown, an inlet 60 from a suction conduit enters a part cylindrical receptacle 10 at the bottom corner adjacent the end wall in which is an outlet 25 communicating with a centrifugal fan 22. Air entering at 60 flows in a helical path to the rear of the receptacle through a grid 59a and filter 59 into a casing 57 thence through a pipe 55 communicating with the sealed outlet 25 to the fan 22. A spray pipe 96 is provided to settle the dust in the receptacle. Air is discharged from the fan 22 through a pipe 30 preferably located on the leading side of the suction nozzle 67 and at the opposite side so that refuse collected at a roadside can be blown towards the nozzle. A brush 100a ahead of the nozzle 67 is mounted on the chassis 12 or on the trolley 68 carrying the nozzle 67. The nozzle is of variable size, a flap on the front wall being pivotable from the driver's cab, and is pivotable about a transverse axis of the trolley 68 and vertically adjustable in relation thereto. There may be a spray 99 in the nozzle and a similar one in the nozzle 94 of an auxiliary suction conduit 93. This conduit 93 is carried by a stub pipe 89 rotatably mounted on the receptacle 10 and passing through the casing 57 into the interior of the receptacle. The receptacle 10 is tiltable about a pivot 11 and a door 19 at its rear is opened and closed by hydraulic rams 13 and 20 respectively controlled by valves in the driver's cab. In alternative embodiments, two centrifugal fans are used in series and two main suction conduits communicate with the receptacle, one at each front bottom corner.
