Title: Improvements in the manufacture of magnetic core memories
IPC: G11C5/05
Filed: 1968-11-12
Abstract: 1,247,026. Magnetic storage apparatus. SPERRY RAND CORP. 12 Nov., 1968 [22 Nov., 1967], No. 53530/68. Heading H3B. In a magnetic core memory array frame comprising a core frame member to which is bonded an insulating member connection pads and extending connection tabs are flush bonded with the surface of the member. A sheet copper foil of larger size than of the finished frame is laminated to a glass-epoxy sheet 12 of somewhat smaller size than the finished frame. After coating one side of the laminate with an insulating mask the exposed side is photoetched to produce the desired pattern of connection tabs 16 and pads 17 and any other associated printed circuitry. The mask is removed and the resultant laminate is bonded to a core frame member 18 provided with apertures 22, 24 for receiving the cores 26, one laminate being positioned on either side of the frame member 18. During this bonding step the tabs 16, and pads 17 become embedded in the sheet 12 so that their surfaces are flush. The core frame is completed by cutting away the sheet 12 lying over the apertures 22, 24, drilling connection holes and tinning the whole. The sheet 12 is of smaller dimensions than the frame member 18 so that during the final bonding step the sheet 12 spreads to the edge of member 18.

Title: Predictive gauge control method and apparatus with adaptive plasticity determination for metal rolling mills
IPC: B21B37/16
Filed: 1969-11-03
Abstract: 1292845 Automatic control of rolling WESTINGHOUSE ELECTRIC CORP 3 Nov 1969 [12 Nov 1968] 53791/69 Heading G3R In a rolling mill, screwdown is automatically controlled to correct any difference between a desired thickness of rolled material and an actual thickness computed from roll force and screwdown position measurements and material plasticity computed from changes of roll force resulting from changes of screwdown position. In Fig.1, the thickness of a hot steel bar 14 is reduced at a series of rolling mill stands S 1 -S 7  (only S 1  & S 6  of which are shown) driven by motors 26 operating at successively higher speeds, the strip produced being wound up as a coil 16. Signals representing the thickness of strip emerging from each stand, computed by digital computers 38 from signals supplied by screwdown position detectors 32 and roll force detectors 34 control screwdown motors 28 to obtain a desired thickness, signals dependent on rate of screwdown being fed back from tachometers 29. Detectors 36, 44 supply signals corresponding to strip width and temperature to the computers 38 which are supplied at 40 with other data such as desired values, calculate mill constants and material plasticity values, and have redundancy and fail-safe features. Material plasticity is calculated from changes in roll force resulting from changes in screwdown position. Anticipatory screwdown correction, suitably delayed, is made at certain stands in dependence on conditions at one or more preceding stands. Compensation is provided for acceleration and deceleration and tail-end effects and computer 38 includes a section responding to and controlling variables of a preceding roughing mill (not shown). Selection from a number of different modes of operation, including manual, is made at a control station 43 and conditions are indicated and recorded at 46. The final thickness is maintained at a desired value by signals from an X-ray gauge 42 exerting a proportional plus integral control of screwdown at a number of preceding stands determined by the magnitude of any error. Tensions between stands are stabilized by signals from loop detectors 41 controlling the speeds of stand driving motors 26 through controllers 50, signals dependent on speed being fed back from tachometers 39.

Abstract: 1,262,600. Swaging machines. GFM GES FUR FERTIGUNGSTECHNIK UND MASCHINENBAU A.G. 12 Nov., 1970 [19 Dec., 1969], No. 53838/70. Heading B3H. A swaging machine has each hammer 3 driven radially of the workpiece by an eccentric 10 surrounded by a block 12 slidable in an apertured rear portion 7 of the hammer. A pair of co-operating guide elements 8, 11 on the aperture and block respectively have meshing helical teeth 13. When the block 12 is moved in the direction of the arrow 16 by the eccentric the teeth cause the hammer to rock in a rotatable sliding guide 4. The working face of the hammer thus moves radially and axially of the workpiece simultaneously. The rear end of the hammer is guided by engagement of a bifurcation 14 with a fixed bar 15 to prevent the working face of the hammer moving out of the plane through the workpiece axis and the eccentric drive shaft axis. The workpiece may be continuously fed rod.

Title: Compensation for distortion in data transmission
IPC: H04B3/04
Filed: 1974-12-30
Abstract: 1486341 Data transmission; testing RANK XEROX Ltd 30 Dec 1974 55967/74 Headings H4P and H4R A plurality of equalization circuits are sequentially connected serially, during reception of test signals, with a receiver input the receiver output, monitored at this time the identification of circuit providing best results being recorded for selection at the end of test for immediately subsequent use. With each equalizer connected, a detector circuit 21 provides an output representative of peak to average difference, equal sections for positive and negative values being provided, which is compared by comparator 27 with the previous value stored in capacitor 29; an output is produced at 31 if the previous value is exceeded. Stage 35 then closes FET gate 25 to transfer the higher value to capacitor 29 and stage 36 of a timing device discharges a capacitor 32 thus priming detector 21 for the next sequence. Each output from 31 enables an AND gate 46, providing an input to clock gates of quad-D latches 42-45 which connect the count appearing in dividers 37-40 to gates 51-54, the coding in which identifies the best equalizer connected so far. When count on 37-40 reaches 16 the Q1- Q4 outputs are zero hence a 1 appears at Q5 of 41 which stops the timing circuit; inverted output Q5 disables gate 46 and through gate 47 enables gate 48 provided an over volt clamp circuit has not been operated during the selection cycle. This enables gate 49 and gates 51- 54 so the count therein is transferred through gates 55-58 to operational amplifiers which connect the preferred equalization circuit serially with the receiver. If the over volt clamp circuit has been operated during the cycle none of gates 55-58 will provide an output and the amplifiers are arranged to connect a compromise equalizer in the channel in response to such zero count. To alleviate effects of noise if it has interfered with the previous cycle it can be arranged that the cycle is repeated by a line ACS connected at inputs of stages 34-36 which shunts capacitor 29; device 41 is reset by momentarily disconnecting its input: afterwards the signal on ACS will restart the count. Comparison is made with U.S. Specification 3,798,576 which contains a similar store and hold circuit to that including capacitor 29 and comparator 27 but the early apparatus only uses the output of the comparator to stop a second run through of the equalizing circuits at the best one but the present arrangement employs a single cycle except in noisy conditions, with the identification of the best equalizing circuit being stored.

Abstract: 1495300 Pressure die casting machine IDRA-PRESSEN GmbH 30 Dec 1974 [10 Jan 1974 11 Jan 1974 12 Jan 1974] 55977/74 Heading B3F  In a cold-die die-casting machine comprising a press cylinder 1 having a piston 2 defining first and second chambers 4, 6, and a multiplier cylinder 9 having a piston 10 defining a chamber 12, metal is introduced into the die (not shown) in three phases in the following manner: (a) In the first phase a shut off valve 27 is closed when hydraulic fluid (oil) is introduced into the second chamber 6 via a line 7 to displace the piston 2 leftwards at a relatively slow speed to slowly push metal into the die. (b) In the second phase, a valve 32 is reversed to connect lines 31, 50 via a line 35 to a tank 34 (at atmospheric pressure) to open valves 27, 45. Oil then passes from a high-pressure store 26 to the second chamber 6 to increase the speed of the piston 2. Oil in the first chamber 4 escapes via a line 41 to a low pressure store 18 and a tank 44, or via an aperture 39. (c) When the back-pressure in the second chamber 6 reaches a prescribed figure a valve 23 is activated by pressure in the line 7 to connect a line 22 to the tank 25 and to open a shut-off valve 20 to allow oil to escape from the multiplier chamber 12. Gas pressure (N 2 ) from a store 16 is then free to move the multiplier piston 10 leftwards at a great speed and hence via a connecting bar 14 impose a very fast leftward motion to the press piston 2 and hence the shot piston. This movement causes the shut-off valve 27 to close since the rapid increase in pressure in the chamber 6 by the insertion of piston-rod 14 forces fluid through the passages in the closure piece 28 to act on the rear side of the piece 28.

Abstract: 1,204,683. Production of dimethyl sulphide. SOC. NATIONALE DES PETROLES D'AQUITAINE. 11 Dec., 1967 [21 Dec., 1966], No. 56269/67. Heading C2C. A process for the manufacture of dimethyl sulphide in two stages comprises reacting methanol with hydrogen sulphide in the first stage to form methyl mercaptan and then reacting the latter with methanol in the second stage to form dimethyl sulphide, the proportion of methanol in the second stage being regulated to a value such that the reaction product of the second stage does not contain more than 5% of methyl mercaptan. The major part of the methanol used in the second stage is generally derived from a portion containing methanol which has served for absorbing the products formed during the first stage of the process and from which the major part of the lightest sulphur compounds it contained have been removed, these being fed separately to the second stage as the crude methyl mercaptan component. The mixture rich in methyl mercaptan and the portion containing methanol are generally admitted to the second working stage at rates of flow such that during the second stage there are 1 to 1.25 mols. of methanol per mol. of methyl mercaptan. The reaction in the first stage is usually carried out at a temperature of from 300 to 350 C. under a pressure of 1.5 to 3.5 bars absolute and with aluminium oxide together with a small portio of sodium oxide as catalyst. The reaction in the second stage is generally carried out at a temperature between 300 and 330 C., 1À5-3À5 bars absolute and with pure aluminium oxide as catalyst.
