Title: Data processing system for finding optimum integer-valued solutions  of linear programmes
IPC: G06Q10/00
Filed: 1972-02-21
Abstract: 1362910 Linear programming INTERNATIONAL BUSINESS MACHINES CORP 21 Feb 1972 [30 June 1971] 7853/72 Heading G4A In a system for the solution of a set of algebraic equations forming a linear program which includes an objective function Z for the linear program and the requirement that certain x i  of the variables x of the solution must be integral valued, an initial linear program is solved, without the integer constraint to derive the optimum value Z LP  of the objective function and if this first linear program does not have the required integral solution a branching operation is formed starting from the initial solved program to form new linear programs, a bound being computed for each linear program on which a branch is to be made to predict the best possible solution Z B  which could be reached by following the branch path and the branching operation is terminated when it is found that the branch will not provide a better value for the objective function Z than a previously found integral solution. In a first method, the initial linear program is solved using the Simplex method and a variable x i  that has a non-integral value is constrained to have the integral values adjacent its value in the optimum solution. If either of these values is feasible, a branch is started with the consequently formed new linear program and bounds are computed to indicate the value which the objective function Z B  is expected to take. Bounds are similarly derived for horizontal branches commencing from other integer values. Vertical branching is obtained by subsequently restricting other non-integral variables to their adjacent integral values to derive further linear programs to be solved. At each stage all the unsolved linear programs are examined and the one given the best value Z B  is solved until an integral solution is found. When an integral solution is found only branches having bounds giving a better value of the objective function are subsequently processed. In a second method, after the solution of the first linear program, the first variable to be restrained to an integral value is chosen to be the variable producing the largest bound. This results in a considerable reduction in the number of linear programs that have to be solved before the optimum integral solution is found. The Specification includes the mathematical theory for computing the bounds.

Abstract: 1,255,732. Variable-draught mole plough. E. A. CLAYTON. 3 Feb., 1970 [13 Feb., 1969], No. 7995/69. Headings A1B and AID.  The coulter 12 of a mole plough is attached to the rear of a support member 10. Tensioncarrying means 14 extend forwardly from a first pivot connection with the support 10 to a second pivot connection with the plough carriage, and are arranged to transmit at least the major part of the tractive effort between the coulter and the carriage. A displacement control device 16 is provided to raise and lower the forward end of the support beam 10 relative to the carriage. In use, an operator controls the flow of fluid to the hydraulic ram 16, making use of sightmarkers (not shown) on the plough carriage and in the ground. The rear of the support beam 10 follows the movement of the forward end since the coulter 12 is of the selflevelling type, so that the support stays in the same orientation relative to the chassis. The coulter thus follows a profile determined by the sight-markers, regardless of the ground profile. The coulter can be raised clear of the ground by means of further hydraulic rams 20 attached between the plough chassis and the tension members 14. A dispenser 24 is provided behind the coulter for laying drainage pipe, the pipe passing through the conduit 26. The dispenser also provides means for laying grit on top of the emerging pipe, comprising a hopper 28 and a slidably adjustable discharge gate 30.

Title: Automatic frequency control in electric signalling systems
IPC: H04L27/16
Filed: 1942-06-12
Abstract: 558,260. Automatic tuning correction; frequency modulation. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. (Radio Corporation of America). June 12, 1942, No. 8079. [Class 40 (v)] In the receiver of a signalling system operating with different frequencies for marks and spaces, the frequency of a local oscillator is controlled by a D.C. voltage obtained from the two frequencies and representative in magnitude and sense of deviations from their desired values. In Fig. 1, the two received frequencies are twice reduced by local oscillators 3, 5 and are passed through a limiter to the signal detector 30. The limiter 6 also feeds a pair of filters 7, 8 which separate the mark frequency from the space frequency each being heterodyned by a local oscillator 10, 12 to give a common beat frequency. This is selected by a filter 29 and passed through a limiter 13 to a frequency discriminator, the rectified output of which regulates the frequency of the local oscillator 3. Thus deviations in the beat frequency from the normal setting of the discriminator adjust the local oscillator 3 to return the beat frequency to normal. In a modification, Fig. 3 (not shown), the separating filters 7, 8 are omitted, and the two oscillators 10, 12 are replaced by a single oscillator the frequency of which is changed by, and in the rhythm of, the detected signals; with the result that the marks and spaces yield a common beat frequency. In a further modification, Fig. 6, the incoming frequencies, after reduction by the local source 3 and limitation at 6, are passed to coupled circuits 70 tuned to the mean of the two frequencies. If the frequency of the local source 3 is correct, marks and spaces produce equal amplitude of response in the circuits 70, and a continuous current in the load resistance of the diode rectifier 70'. If there is a tuning error, pulses of current pass through the primary coils P', P<SP>2</SP> of transformers 72, 73 which are in parallel with the rectifier load resistance, the polarity of the pulses depending on the sense of the tuning error. Signals from the detector 30 are passed through other primary coils P<SP>3</SP>, P<SP>4</SP> on the transformers 72, 73, the direction of winding of one coil being reversed. Each secondary winding is centretapped and connected as a full-wave rectifier 74, 75 to a load resistance 78, 79 ; and the algebraic sum of the voltages arising across the resistances is used to operate a frequency-control device 23 associated with the local source 3, to rectify the tuning error.

Abstract: 526,335. Albumens. METALLGES. AKT.-GES. March 13, 1939, No. 8082. Convention date, March 12, 1938. [Class 2 (iii)] Durable dry albumen is obtained from dried milk (including skimmed milk) by dissolving the dried milk at elevated temperature in a mixture of water and a monohydric or dihydric alcohol mixable with water, or a ketone or ester, cooling the solution, and separating and drying the precipitate obtained from the liquid. The precipitate is preferably washed before drying, and may be dried in the form of a suspension in water or the washing liquid, e.g. by spray drying. As solvents used in conjunction with water, methyl, ethyl propyl and isopropyl alcohols, acetone, ethylmethylketone, methyl formate, and compounds containing other substituents, such as halogen atoms or amino groups, in addition to OH groups, are specified. The dissolving operation may be carried out at or near the boiling point, e.g. by boiling under a reflux condenser. In an example, skimmed milk powder is boiled under reflux with 50 per cent. ethyl alcohol and the colloidal solution obtained is allowed to cool and the casein separating out is washed with water and dried.

Abstract: 1,173,794. Grinding gears. LEAR SIEGLER Inc. 21 Feb., 1967 [2 March, 1966], No. 8109/67. Heading B3D.  A gear-grinding machine comprises a carriage 16 mounted on a frame 10 for longitudinal movement, a work spindle 32 rotatable on the carriage about an axis parallel to the direction of movement, and an adjustable sine bar mechanism 22 interposed between the work spindle and frame to cause rotation of the spindle in response to movement of the carriage, the mechanism consisting of a sine bar 24 on the frame and a follower 26 connected to the spindle, or vice versa, the sine bar or the follower being adjustable in a direction transverse to the direction of movement of the carriage. The work spindle has a fixture 18 for holding a workpiece 20, such as an internal gear, which is to be formed with helical teeth by a grinding wheel 14 carried by a column 12 adjustable about a vertical axis. The spindle 32 is connected by rack-and-pinion mechanism or tapes wrapped around a base roll to a bar 28 which is slidable perpendicularly . to the axis of the spindle and carries the follower 26 engaging the sine bar 24. The latter is secured to a block 46 slidably adjustable in a swivel member 52, adjustable about a pivot 54 by a worm 66 engaging an arcuate rack 64 secured to the member 52. The pivot is mounted in an intermediate slide 56 adjustable perpendicularly to the work spindle axis on a slide 36 by a screw 82, the slide 36 being adjustable along the base 10. Adjustment of the intermediate slide causes movement of the bar 28 and hence rotation of the workpieco for stock-dividing, i.e. adjustment of the workpiece for grinding both sides of a tooth space simultaneously. To facilitate engagement of the follower 26 with the sine bar after the carriage 16 has been moved to permit dressing of the grinding wheel, a lead-in bar 100 is pivotally connected at one end to the sine bar and at the other end has a slot 116, Fig. 4, engaged by a pin 114 on a lever 104 urged about a pivot 106 by a spring 110. The spring eliminates shock as the follower engages the lead-in bar and is guided on to the sine bar 24.
