Title: Improvements in or relating to apparatus for transporting sheet metal coils and other heavy items from a receiving station to a delivery station
IPC: B21C47/24
Filed: 1967-07-06
Abstract: 1,125,214. Reciprocating conveyers. VEREINIGTE OSTERREICHISCHE EISENUND STAHLWERKE A.G. 6 July, 1967 [4 Aug., 1966], No. 31218/67. Heading B8A. Positioning means for heavy loads, e.g. sheet metal coils, received by a reciprocating conveyer, is controlled by a light beam device in combination with a further light beam device or with mechanical means. As shown, the positioning of a coil 1 at a receiving station I of a reciprocating conveyer is controlled by a first light beam device 20, 22 and by a second beam device 19, 21. Transmitter-receivers of the devices 19, 20 move in opposite directions. to and away from the leading and trailing ends of the coil 1, when a motor 30 is operated. If the coil has been received at a station I on a conveyer beam 2 with an error of +X relative to a plane of symmetry 18, initiation of a correction procedure, e.g. from a control desk, causes transmitter-receivers 19, 20 to move towards the coil. Device 19 first detects the coil and forward movement of the beam 2 is started. The device 20 next detects the forward end of the coil and the beam 2 is stopped, the coil being correctly positioned. A table 7 then lifts the coil and the beam 2 is returned to its initial position. The devices 19, 20 are next de-energized and are restored to their original positions after which, as a working conveying stroke of the bar 2 is initiated, the coil is lowered on to the bar and is moved, step by step, through intermediate stations III, IV to a delivery station II. When there is a position error of - X the coil is moved in a direction reversed from that for the + X error. In a modification, Fig. 5 (not shown), the coil is always deposited at the receiving station with a position error +X and the members (19, 21) are replaced by a stop (35) which is adjustable and coupled to the support for the member (20). In further constructions, Figs. 6, 7 (not shown), a fixed stop (40) is initially engaged by the coil and movement of the member (20) towards the coil is produced by correction movement of the beam (2).

Title: Improvements in or relating to the detection of hydrocarbons
Inventor: BENE GEORGES JEAN
IPC: G01V3/32
Filed: 1966-07-12
Abstract: 1,128,828. Electromagnetic detection of hydrocarbons. INSTITUT FRANCAIS DU PETROLE, DES CARBURANTS ET LUBRIFIANTS. July 12, 1966, No. 31318/66. Heading G1N. The detection of hydrocarbons in subterranean formations is based on the principle that, in a field H 01  the nuclear magnetic resonance spectrum of a hydrocarbon comprises three peaks, Fig. 4 (not shown), the central peak having a frequency v=4257 H o  c/s and two symmetrically arranged satellite peaks of frequency v=(4257 H o  Œ62)c/s, the former peak being due to the resonance of the free protons (H') and the latter peaks being due to the resonance of the protons (H') bound to the C<SP>13</SP> atoms in the hydrocarbon. As water has a very similar nuclear magnetic resonance spectrum comprising a single peak, again of frequency v = 4257 H o  c/s, due to the resonance'of the free protons (H'), it is the presence of the satellite peaks which indicates that a hydrocarbon is present. Thus from a measurement of the areas h, H of the satellite and central peaks, an indication of the proportion of a hydrocarbon to water present can be obtained from the formula: - In the embodiment, the formation, constantly subjected to a field H o , e.g. the earth's field or the resultant of the earth's field and an applied field, is initially subjected to a further prepolarizing field H p  which causes the total magnetic moment of the protons Áp to become aligned with it. When the field is cut off, the magnetic moment precesses round the field H o  and gradually becomes aligned with it. The resonance signals have the form shown in Fig.2 (not shown) for water alone or in the form shown in Fig. 3 (not shown) for hydrocarbons. A coil 2 Fig. 1 serves both as the prepolarizing field coil and pick-up coil and is alternately connected to a D. C. generator 5, and an amplifier 6 and recording means 7 by a commutator 3 controlled by a pulse generator 4. The D.C. generator may be replaced by a square wave pulse generator, whose pulses have a duration corresponding to the prepolarizing time, and which is associated with a derivative means for generating pulses corresponding to the front and rear of the square wave pulses by which the commutator is controlled. In operation, after the field H p  has been cut off, the recorder receives the resonance signals which may be recorded on a magnetic register or recorder from which all the required information can be subsequently extracted. Alternatively it may be fed to a single band pass filter which is adjusted in turn to the resonance frequencies so that the intensities of the signals may be measured. The signal could also be fed simultaneously to two or three band pass filters, each having a tuning frequency equal to one of the resonance frequencies whose intensities are to be measured. A conventional band pass filter which could be used, is described with reference to Fig. 5 (not shown).

Title: Memory arrays
IPC: G11C7/02
Filed: 1970-06-29
Abstract: 1309463 Magnetic storage arrangements INTERNATIONAL BUSINESS MACHINES CORP 29 June 1970 [30 June 1969] 31330/70 Headings H3B and H3T A storage matrix drive line 6-1, Fig. 1A, has a transistor switch such as 100-1 at each end to allow connections to be made to a transformer 20 which supplies both read and write pulses The arrangement is such that though current flows through the line in opposite directions during reading and writing, the flow through the switch is always in one direction. Fig. 1A shows the left hand ends of groups of row lines 6-1 to 6-M and 8-1 to 8-M, each group being connectable to the transformer 20 by a corresponding transistor switch 100-1, 100-N. The connections at the other ends of the row lines are shown in Fig. 1B, and are such that activation of a pair of transistor switches such as 100-1 and 150-1 provides a closed path to the transformer 20 for one line only, in this case line 6-1. By driving the lines with transformer 20, earth returns are avoided and noise is reduced. Writing.-To write in a given storage element on a row line, a pulse of write polarity is passed through that line and a coincident pulse is passed through the appropriate column conductor (not shown). To pass a write current pulse into line 6-1, transistor 100-1 is switched preferably as described in Specification 1,003,636 by a pulse from windings 103-1 and 105-1 of a transformer 104-1, the transformer receiving a pulse in response to address circuitry (not shown, which closes gates 116 and 108-1. The transistor 150-1 is similarly switched using gates 161 and 160-1. Some 25 nanosecs. after a switching drive circuit 43 produces a pulse of write polarity in the secondary 21 of transformer 20. This pulse forward biases diode 101-1, and the pulse passes through that diode, transistor 100-1, diode 125-1, line 6-1, diode 153-1, transistor 150-1, diode 151-1 and back to the secondary 21. A pulse which occurs simultaneously in the other secondary 23 serves to back bias diode 110-1 to define the above path. The pulse produced by the drive circuit is terminated before the transistor switches are opened, thereby preventing changes of breakdown. Reading.-The operation is similar to writing, using coincident currents, but the polarity of the row current is reversed. The sense and column conductors are not shown. Transistors 100-1 and 150-1 are first switched, then after 25 nanosecs. transformer 20 is pulsed by the drive circuit 43 to give a read pulse from secondary 23 which passes through diode 154-1, Fig. 1B, transistor 150-1, diode 152-1, line 6-1, diode 102-2, transistor 100-1, and diode 110-1 back to the secondary. The similar pulse from the other secondary, 21, back biases diode 151-1 to define this path. The transistor switch at one end of a line may be replaced by a pair of transistors arranged as in Specification 1,088,737.
