Filed: 1922-05-26
Abstract: 180,689. Wessels & Wilhelmi. May 28, 1921, [Convention date]. Drawings to Specification. Retort furnaces; multiple-chamber kilns.-The destructive distillation of fuel, more particularly peat, is effected in ovens which are connected and operated after the manner of a continuous kiln. The apparatus comprises a number of chambers arranged in " ring " formation and heated by external flues, through which the heating gases flow upwards and downwards alternately. In operation, one section of the chambers will be cooling off, after firing, the cooling being effected by air which is passed through the flues on its way to the adjacent firing section. From this section the products of combustion are passed through the flues or other chambers in which the charges receive a preliminary heating. The operation is so controlled that a charge is heated up to its maximum temperature in about four days. Reference has been directed by the Comptroller to Specification 116,455.

Title: Digital computing system
IPC: G06F13/26
Filed: 1966-04-04
Abstract: 1,148,262. Data processing systems. DIGITAL EQUIPMENT CORP. 4 April, 1966 [5 April, 1965], No. 14866/66. Heading G4A. In an electronic digital data processing system, at least one processor is connected to a plurality of input-output devices with which it operates by a single bus and/or to a plurality of memory devices with which it operates by a further single bus whereby further devices may be added with ease. As shown (Fig. 1), processor 12 is connected to input/output devices 22, 24 and 26 and to drum system 32 by way of a bus 20 and is connected to memory devices 14, 16 and 18 by way of a bus 10. Processors 34 and 42 have similar buses to the devices with which they operate. In operation, a processor issues select signals to select the particular device with which it wishes to communicate, instruction signals to determine the operation to be performed by the selected device and either receives or transmits data signals and data lines of which there may be 36 in each bus. The processor operates in an asynchronous mode. Input/ output devices may request communication with a processor, acceptance of which request is made according to a system of priorities. The memory devices each have control means for accepting request from the processors according to an order of priorities, processor P 0  having highest priority followed by that one of processors P 1  or P 2  which did not last have access (of priority circuit 158, Fig. 4, not shown). Two of the memory devices 14 and 16 comprise magnetic core memories and the other 18 a set of 16 fast flip-flop registers. These registers have the same addresses as the first sixteen words in core memory 14, a mode switch (210, Fig. 5, not shown) being provided to determine whether the registers 18 or the cores 14 are utilized. The memory cycle may comprise read only, write only or read/write functions. The read/write operation may be temporarily interrupted after the read part of the cycle (of timing circuits 192a and 192b, Fig. 7, not shown) so that the operand just read out may be rewritten in the original storage location after being operated on in the requesting processor. The memory devices connect with the buses that serve them for only a fraction of their memory cycle so that a processor can transfer successive data words with different memory devices more rapidly than with the same memory device. Circuit means 102 (Fig. 3, not shown) in the processors are provided to apply a large reset potential to rapidly discharge the data lines during data transfer operations.
