Title: Logical circuits
IPC: G06F9/32
Filed: 1963-10-16
Abstract: 1,057,224. Digital computers. RADIO CORPORATION OF AMERICA. Oct. 16, 1963 [Nov. 14, 1962], No. 40926/63. Heading G4A. An asynchronous data processor includes a circuit which in response to a machine instruction signal directing a particular operation to be performed, allows performance of that operation only when the previous operation has been completed. As described, a circuit (Fig. 2, not shown), for the addition of two (n+ 1)-bit operands in registers (16, 23), includes an asynchronous binary adder (24). Assuming an operand to be already stored in one register (23), a first machine instruction (MI1, Figs. 3 and 5, not shown), is applied to set a flip-flop (80) in a control circuit (Fig. 5), thereby providing a " read-in " signal (J) for the register (16), which signal is applied to a terminal (29, Fig. 2) of the circuit. A second machine instruction (MI2) which controls addition is applied to set another flip-flop (82) in the control circuit (Fig. 5), but no " add " command (F) is produced by the control circuit until a " read-in completed " signal (G, Figs. 3 and 5), resets the first flip-flop (80) to provide a " 1 " input to a NOR gate (84) whose consequent " 0 " output is combined in an OR circuit with a " O " output from an inverter (86) connected to the set side of the second flip-flop (82). The output of the OR circuit is inverted (88) to provide a " 1 " signal (F, Figs. 3 and 5), which is applied to another terminal (30, Fig. 2), to initiate operation of the binary adder (24). If the second instruction (MI2) does not arrive until the first instruction signal (MI), and the " read-in completed " signal (G) have occurred, the control circuit (Fig. 5) causes the " add " command to be produced concurrently with the second instruction (MI2). The " read-in completed " signal (G) is produced by a circuit (Fig. 4, not shown), comprising n+ 1 comparison stages comprising AND and NOR gates which stages compare the signals on the input and output lines of the register (16). A pulse generator (110) is actuated to produce a pulse only when all the comparator stages indicate equality, i.e. the input number has been completely stored in the register (16). A NOR gate (94) indicates an error condition if an (MI1) instruction occurs before the " add " command has been completed. A logical equivalent, including an AND gate and a bi-stable flip-flop, of the control circuit (200, Fig. 5), is described (Fig. 7, not shown). By the inclusion of a further similar circuit, a control circuit producing correctly timed commands from three machine instructions can be provided (Fig. 6, not shown).

Abstract: 1,009,422. Haymaking machines. C. VAN DER LELY N.V. Nov. 16, 1961 [Nov. 22, 1960], No. 41137/61. Heading A1F. A haymaking machine comprises a frame beam 1 carrying two rake wheels 4, 5 and a beam 9 supporting at its end two plates 12 between which a sleeve 14 is arranged to pivot about a pin 15. A beam 21 carrying two further rake wheels is detachably supported in the sleeve 14 by means of a hook 29 fixed to a lug 26 on the beam engaging over a lug 28 and a pin 33 engaging aligned holes in the lugs 26 and 28. By disengaging the pin 33 the beam 21 can be rotated through 180 degrees about its axis, after which it may be pivoted together with sleeve 14, horizontally about pin 15 to bring it into the position shown in dot and dash lines in Fig. 1. A locking pin 19 engaging holes 18 in the plates 12 and holes in lugs 17 attached to the sleeve holds the beam 21 in position. A transport position in which the beam 21 extends substantially in the intended direction of travel is also envisaged. For use as a side delivery rake the beam 21 is disengaged from the sleeve 14 and is engaged with a connection 37, 38 on the beam 1 as shown in dash lines in Fig. 1. In a modification the end of the beam 21 which engages with the sleeve 14 is offset from the length of the beam whereby the beam, rake wheels combination turn about a line passing through their centre of gravity. In a modification (Fig. 6) a frame beam 67 has connected thereto a beam 53 which provides at its end a sleeve to rotatably receive a stub shaft secured to a further sleeve 57 which is adapted for connection to a frame beam 58. This beam together with the sleeve 57 may be turned about the axis q through 180 degrees to the position shown in dot and dash lines and is locked in position by a pin 68. The beam 58 may be detached from the sleeve 57 and is adapted at 35, 36 for connection to the beam 67 as shown in dash lines. In a further embodiment (Fig. 8) a beam 71 has attached to it a beam 77 curved in a vertical plane and having a pin 81 on which is journalled a beam 82 for pivotal movement about an axis B to the position shown in dot and dash lines, a locking pin 90 being provided. The beam 82 may be detached from its pivot and secured to the beam 71 as shown in dash lines. In this case the rake wheels 59, 60 have to be removed from the axis to be turned so that they operate in the right direction.

Abstract: 1,191,955. Data processor. SIEMENS A.G. 30 Aug., 1968 [1 Sept., 1967], No. 41404/68. Heading G4A. A data processing system for processing sequences of signals in which each signal forms part of a data word and is accessed from a store by an address longer than a word address and in which information required for processing is distributed among several command words is characterized in that the initial address of each signal sequence is transferred to a register associated with the control system prior to the execution of the operation and a command word containing information about the limit on the signal sequences and the nature of the operation triggers the operation. The invention relates to transfer from store to store of signals forming part of a data word, the data word holding an integral number of signals In the Example (Fig. 2) a signal comprises 6 bits, a data word 24 and a word address 15. The address signal is used to find a particular word and two extra bits in the least significant places indicate which of the four signals in the word is required. Each time a signal is transferred "1" is added to the address to identify the next signal in the sequence. The address of the first signal to be transmitted is transferred to register AR1 and the address of the receiving cells is transferred to register AR2. The first command word is then obtained. This contains an operations section OP and sections EZ, EM and ZZ determining the length of the sequence. The sequence length can be determined either by the number of signals indicated by ZZ or by a special code held in the last signal in which case comparison with EZ determines the end signal. EM is used to indicate which of the methods is used. Sections S and I are used for address modification in other operations and are redundant in this operation. The system can be used to process teleprinter signals.

Abstract: 1,175,936. Electroconductive coalings. KALLE A.G. 3 Sept., 1968 [4 Sept., 1967], No. 41853/68. Heading B2E. A polyester film has on one or both surfaces a layer of electroconductive particles firmly attached to the film surface without the presence of an applied binding layer. The film is prepared by treating the base film with a solvent or swelling agent for the film and depositing a layer of particles on the surface and removing the solvent or swelling agent by heat. The solvent or swelling agent may be applied with the particles as a suspension or, alternatively, it may be applied in such a quantity as to produce an effective softening effect on the surface, removed so that the surface is still receptive to the particles and then the particles applied before removing the residual solvent or swelling agent. The film may be of polyethylene terephthalate and this may be stretched in one direction at a rate of 1:1.5 to 1:6 or it may be biaxially stretched from twice to 25 times the original area. The film may be heat set. The electroconductive particles may be of carbon black or of metal. Numerous phenols, halogenated hydrocarbons and halogenated lower fatty acids are specified as solvents or swelling agents. Dispersing agents may be used when the particles are applied in the solvent or swelling agent and anionic detergents or non- ionic detergents are exemplified.

Abstract: 1,255,870. Ultrasonic inspection devices. COMMISSARIAT A L'ENERGIE ATOMIQUE. 5 Sept., 1969 [13 Sept., 1968], No. 44097/69. Heading H4D. In a system for inspecting a circular weld ultrasonically the weld is scanned helically by a transducer and time-gated echo signals from the weld are fed to an echo amplitude recorder having a recording head which is moved along a spiral path, each turn of the spiral corresponding to a complete rotation of the transducer about the weld axis. In the Fig. 3 embodiment for inspecting the circular weld 28 between a sleeve 23 and a plate 24, plug 33 provides a seal for water couplant in which transmit/receive transducer 30 is rotated and raised to give a helical scan of the weld. The X and Y deflections of a plotter stylus are synchronized with the transducer rotation by means of sine/cosine potentiometer 46 and the plotter trace is expanded by means of linear potentiometer 44 as the transducer is raised, thereby giving a spiral record. Echo signals are applied to a time gate 40 to select weld echoes and the weld echoes may be fed to a four-channel amplitude-analyser 42 whereby only echoes above a threshold amplitude (i.e. indicating weld flows) are recorded and whereby such echoes are recorded at the appropriate one of four tonal values. The transducer rotation rate may be programmed such that the plotter stylus speed does not vary with diameter of the plotted trace. A polar co-ordinate plotter or an oscilloscope may be used instead of the X-Y plotter. Constructional details of the transducer scanning mechanism are given (Figs. 8 and 9, not shown).

Abstract: 1,097,570. Photo-electric pyrometers. LAND PYROMETERS Ltd. Oct. 4, 1966, No. 44272/66. Heading G1A. A pyrometer of the type in which radiation from a hot body is divided by a beam splitter to fall on two photo-cells with different spectral sensitivities is constructed with symmetry about the optical axis so that the angular position of the pyrometer is not important when the radiation from the body is polarized. The hot body is focused by an objective 14 on to a field stop 17 which may contain a lens 18. The field stop is focused by a lens 20 and a transparent mirror 38 which may be unsilvered or lightly silvered on to two detectors 26, 22. The detectors may be of different materials e.g. silicon and selenium or differently treated selenium so as to have different spectral responses. Alternatively a filter (25, 37) may be provided in front of one or both detectors or the mirror may have an interference layer or be made of a material which transmits one spectral band and reflects another. Electrical circuit. The cells 22 and 26 generate voltages across loads 41 and 39 which are compared by an amplifier 40 and any difference energizes a motor 46 to adjust the potentiometer 42, 43 to reduce the difference and move the pen 54 of a recorder. A thermistor 36 compensates for variations in ambient temperature. When the output of detector 26 falls below the minimum level at which the pyrometer will give a reliable reading, relay 59 drops out to energize relay 57. This connects the battery 55 to measuring system so that the recorder pen is driven to its zero position.
