    • A governor for combustion engine driven compressors includes two piston members. The first piston member is actuated by oil pressure and a second piston member is actuated in an opposite direction by the compressor discharge fluid pressure. The governor is responsive to the differential between a predetermined low working pressure and the compressor discharge fluid pressure. A governor spring member acts to move a fuel control member for the engine between an idle position and full speed position. The governor spring member is subjected to power bias by the two piston members under various operating conditions. The governor includes an unloading control valve which is movable to unloading and loading positions when the fuel control member is adjacent the idle position. A compressor inlet valve and compressor vent valve are provided for loading and unloading the compressor. The second piston member controls the fuel supply in response to compressor delivery of compressed fluid when the plant is operating between an intermediate and full capacity.

    • A control device for turbo charged diesel engines for varying the position of the fuel injection pump governor full load stop to provide excess fuel during engine cranking and to limit full load fuel delivery during acceleration and low speed operation. The device includes a cylinder, one end of which is connected to a source of engine lubricating oil and the other end of which is subjected to engine manifold pressure. An oil pressure responsive piston in the cylinder carries therewithin a smaller manifold pressure responsive piston which is connected directly to the governor full load stop to control the stop position. The pistons are each spring-loaded against the force of their respective actuating fluids whereupon an absence of oil pressure will produce an excess fuel position of the full load stop, and a drop in manifold pressure during engine operation will result in a fuel limiting position of the full load stop.
    • 用于涡轮增压柴油发动机的控制装置，用于改变燃油喷射泵调速器满载挡块的位置，以在发动机起动期间提供过量的燃料，并且在加速和低速运行期间限制满载燃料输送。 该装置包括一个气缸，其一端连接到发动机润滑油源，另一端承受发动机歧管压力。 气缸中的油压响应活塞在其中具有较小的歧管压力响应活塞，其直接连接到调速器满载停止件以控制停止位置。 活塞每个弹簧加载抵抗其各自的致动流体的力，因此没有油压将产生满载停止的过量燃料位置，并且在发动机运行期间歧管压力的下降将导致燃料限制位置 满载停止。

    • 859,846. Electric digital-data-storage apparatus. ELECTRIC & MUSICAL INDUSTRIES Ltd. March 22, 1957 [April 4, 1956], No. 10237/56. Class 106 (1). A storage device comprises a matrix of storage elements, means for applying thereto data signals to be stored, and means for applying sequentially to the rows of elements read-out signals to reproduce the stored data signals the arrangement being such that only particular rows are read out to a given destination. In a first embodiment the six columns of a matrix, Fig. 1, are identified with a six-element binarydecimal, alpha-numeric code. Entry of codeddecimal digits is from a buffer store 2 in response to a control signal on line 3; a corresponding magnetic representation is set up in the cores C of any row of the matrix which at the same time is sensitized by a read-in pulse on the respective X control circuit. When read-out pulses are applied in sequence to the X control circuits X1 to X10 the output signals are distributed to various output registers R1, R2, R3 in accordance with a pre-arranged scheme. As shown, rows 1 to 4 and 10 of the matrix are read out to register R1, rows 5 to 7 to register R2, rows 8 and 9 to register R3, and so on. Such arrangements are intended for built-in sub-routines in a computer. In another embodiment an extra column of cores Cp, Fig. 2, is employed. The output register R1 is insensitive to signals on the read-out lines D11 to D16 unless it receives a pulse from gate 7 simultaneously. This only occurs when the row being stimulated by an X-read-out pulse includes a Cp core in the " 1 " state. In another embodiment a counter 9, Fig. 3, opens in succession gates 13, 15, 17 routing information from the matrix SM in accordance with a prearranged scheme. The counter is stepped on each time an X-signal finds a Cp core in the " 1 " state and is returned to zero when the last row of the matrix has been read out. In another embodiment (Fig. 4, not shown) two columns of Cp cores are provided, one controlling a switch permitting output signals to pass through the read-out register of the matrix and the other controlling a switch inhibiting read-out of signals. The switches are cross-connected to form a trigger pair. In another embodiment a series of matrices of the type shown in Fig. 2 are each associated with an additional " skip core Cs, Fig. 5. A shift register 24 controls the sequence of read-out signals on the X lines of each matrix while a second shift register 20 determines which matrix is to be read out in a sequence. A " marked " matrix (e.g. SMn) receives an appropriate potential on a line 22 and also via a differentiator 26, a gate SGn receives a pulse in synchronism with the read-out pulse delivered to the " skip " core Cs. If the core Cs is found to be in the "1" state an inhibiting signal is applied to the gate SGn and the pulse from the differentiator 26 has no effect; if, however, the core Cs is in the " 0 " state, the pulse from 26 passes through the gate SGn to the input of the shift register 20 stepping it on immediately to the next stage to examine the next matrix and thus skipping the row-by-row scanning of the matrix SMn. In yet another embodiment (Fig. 6, not shown) the possibility of re-arranging the sequence of the digits by transferring certain ones to a submatrix in a different order before reading out, is demonstrated. A store in accordance with the invention may comprise a plurality of submatrices each of which may consist only of programme and skip cores Cp and Cs suitably arranged in rows and columns.
