Filed: 1971-12-06
Abstract: 1376182 Digital transmission; reduction of distortion FUJITSU Ltd 6 Dec 1971 50017/71 Heading H4P To increase discrimination and reduce inter symbol interference to improve reception of signals distorted by a line, transmitted signals are altered in amplitude dependent on the relation of the previous bit i.e. where a 1 follows a 1, no amplitude adjustment is made but where a I follows a 0 amplitude is increased by say 1/0À9. Similarly a 0 following a 0 is unaltered but a 0 following a 1 has its amplitude depressed to minus 1/0.81. Two input binary chains may be diplexed on to a common channel. Each train passes through a modulator such illustrated in Fig. 6a comprising clocked gates 14a, 14b receiving normal and inverted bit data bits from terminal 12, which set and reset a bistable circuit 15. The previous data bit is stored in bi-stable 21 and comparison through gates 18, 20, 23 controls current drivers 19, 24 which set the level of output signal as indicated in Figs. 6b, 6c (not shown). The principle can be extended to 2<SP>n</SP> phase systems where n is greater than 2 and to n levels. In the specification 8 and 16 phase psk signals are envisaged providing up to 16 output levels.

Title: Internal combustion engines having ignition timing control apparatus
IPC: F02P5/06
Filed: 1975-12-17
Abstract: For the automatic advancing and retarding of the firing point of the internal combustion engine, the vacuum of an intake line is applied to a "slow" or a "fast" vacuum chamber (28 and 29) of an adjusting device, the diaphragm (30) of which displaces a control element (22), by a control device (32, 61), which in contrast to known ignition timing devices has only a single three-way control valve (32). A venting device (40) connects the vacuum chamber (28 or 29), currently not acted upon by the vacuum, to the atmosphere by way of a venting aperture (47, 50) assigned to the latter and has a second diaphragm (44) with closing element (45) in order to automatically close the other venting aperture (47 or 50). A device (55) responding to temperature automatically interrupts the connection of the three-way control valve (32) to the intake line (11) when the ambient temperature of the engine is below a certain value. In this case both vacuum chambers (28, 29) are vented and both diaphragms (30, 44) and the control element (22) adopt neutral positions so that the firing point assumes an intermediate value. <IMAGE>

Abstract: 1,070,424. Electronic computers. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 22, 1964 [Dec. 23, 1963], No. 52005/64. Heading G4A. A computer has two registers for storing the addresses of two operands stored in a memory which is addressed by character, each machine cycle including the read-out from memory of a pair of characters of each operand and the processing of either one or two characters from each operand, and there being means to modify the stored addresses by one and two respectively and later in the machine cycle to remodify the first address if two characters were processed of each operand and the second address if one character was processed of each operand. The unmodified second address is stored after the second address has been modified by two so that the unmodified address can subsequently be modified by one whereby remodification of address is carried out in the same direction as modification of addresses. The computer described is the same as that in Specification 1,070,423 which is referred to, except for an additional "wrap error" feature as follows. If, during address modification, an address is incremented above the highest address in the memory (giving a low address) or decremented below the lowest address (giving a high address), a wrap error signal is produced (Fig. 116, not shown) from the highest order digit on the address bus together with the carry or borrow signal from the next highest order digit in the address modification circuit. If, and only if, the wrap error signal is still present after any modification of address later in the machine cycle (i.e. the address is still invalid), then the wrap error signal is fed to OR gate 702 (Fig. 41, not shown) to stop the computer &c. (as in the Specification mentioned above).

An automatic bobbin winding machine of the kind in which on thread breakage automatic retying takes place; includes means whereby if a thread breaks outside the effective range of the thread gripper and the partially unwound supply cop is, as a result, ejected, the ejected partially unwound supply cop is automatically returned to a common collecting container holding new cops and cripple cops (cops with an irregular peripheral surface) each cop after delivery from the common collecting container being probed as regards its peripheral shape, the result of the probing being utilized as a control for modification of the direction in which the cop falls in relation to the cop holders of the winding machine. In Fig. 4 empty and partially unwound supply cops are transferred by a transporting device 46 to a station 47 where the empty cops drop through an opening into a bin and the partially unwound cops are passed to a further conveyor 48 to raise them above a common collecting chamber 26 containing fully wound cops and cripple cops 19. As each cop is released from the container 26 it drops onto a table 27 where it is probed by a sensing device 28 to determine any variations in the peripheral shape of the cop and so control the angle of inclination of the drop guide 29 between the container 26 and bins 15 of a circular intermediate supply magazine. The intermediate supply magazine rotates with step-by-step motion and before the cops therein are discharged along a chute 35, a further sensing device 37 operates in the same manner as the sensing device 28 to control the angle of the chute 35 in order that the discharged cop shall drop correctly onto a receiving pin or cop carrier.
