Abstract: 1,274,794. Programmed control. INTERNATIONAL BUSINESS MACHINES CORP. June 8, 1970 [June 23, 1969], No.27553/70. Heading G3N. A programme selection system comprises a circulating data store which stores a plurality of keyed data fields, manually operated programme selection means to request a selected programme and control circuitry for delaying a change in programme until a predetermined portion of the next data field is keyed. As shown, a keyboard 10, comprising data keys, a space bar, and a plurality of programme function keys, provides, through encoding logic, signals on an output buss 30. The depression of a data key causes, through a buss 148, the storage of information bits in an electro-acoustic delay line of a storage 12 which is maintained in circulation by a clock 82 over a lead 150. The program data from a read station 152 is also held in storage 12. The contents of the storage 12 is available over a buss 146 through an AND gate 144 to a program data logic 14 controlling the various programmed functions to be performed by a keypunch, not shown. The depression of a program key causes, over a line 172-178, an immediate change of program in logic 14 when the machine is physically in the first character of a field or, alternatively, when a key is depressed when the machine is within a field, prior to the end of a field, the storing of the direction for a change until the last character of the field is entered and just prior to the first column of the neat field. A field is defined as a group of characters in a complete record, for example, a N characters corresponding to N columns of a document card. A signal on a line 172-178 is fed through an OR gate 162 to set a flip-latch 32-38 by an AND gate 40-46. A programme change latch 92 is set through an OR gate 104 from an AND gate 108 to cause an immediate change of program during a first column of a field, as indicated on a line 110 from logic 14. The latch 92 is also set by an AND gate 96 for a deferred programme change in response to a signal from an OR gate 96, connected to latches 32-38, and a signal on line 102 existing when the last entry in a field has taken place. A program change is initiated by latch 92 setting a latch 62-68 the output of which through an AND gate 116-118 at a clock-time P1-P4 to provide a signal from an OR gate 132 to open an AND gate 144 to transfer data of the desired programme from the storage 12 to the program data logic 14.

Title: Improvements in or relating to balancing machines for determining the running out-of-balance of rotary bodies
Inventor: DREW DENIS ARTHUR
IPC: G01M1/04
Filed: 1951-11-27
Abstract: 714,351. Testing balance of rotary bodies. ROLLS-ROYCE, Ltd. Nov. 27, 1952 [Nov. 27, 1951], No. 27846/51. Class 106 (2). [Also in Group XXXVIII] A balancing machine for determining the running out-of-balance in a pair of spaced planes of a rotating unbalanced body, comprises axiallyspaced supports for the body and means adapted when the rotary body is stationary in the, supports, to produce oscillations of the supports simulating the oscillations that would be produced by a rotation of the body with a relatively large out-of-balance mass added to one of the planes. Thus the preliminary setting up operation, in which the out-of-balance indicating means is adjusted so that the out-of-balance in one plane does not cause an indication of out-of-balance in the second plane, can be performed without rotating the body and applying additional out-ofbalance masses. The. machine. Fig. 1, comprises massive end portions 10, joined by guide rods 11. Two cradles 13, adjustable along the guides by handwheels 13a. include supports 13b for the body to be balanced, the supports 13b being capable of oscillation in. a horizontal direction at right angles to the guides 11. The supports 13b are oscillated through rods 15 by a bar 14 which is mounted so as.to oscillate in a horizontal plane.' The oscillations are created by electric motors 16, Fig. 2, mounted on brackets 17 on the bar 14, the spindle of each motor carrying an out-ofbalance fly-wheel 19 which, on rotation, causes the bar 14 to oscillate. Only one motor at a time is used during the setting-up operation. The motors are not used during the actual testing of the body. The bar 14 is supported by a plurality of forked frames 21, each of which has its lower end clamped to a block 22. Gripped between the block 22 and the lower ends of the limbs are a pair of flexible steel strips 23, the upper ends of which are secured to a sliding block 24 mounted on a guide rod 25 supported by brackets 26 on the end portions 10. The bar 14 is thus free to oscillate in a horizontal plane. To rotate the body during the test for want of balance, a wheel 27 is clamped around the body near its centre of gravity, said wheel 27 being driven by a motor through suitable belt means 28 and 35. The bracket 17 may also carry a mounting 20 for the moving part of means not shown for producing electric signals corresponding to the oscillations of the nodular bar 14. The mountings 20 may carry the magnet of a moving magnet generator or a coil of a moving coil generator.

Filed: 1945-10-23
Abstract: A material for purifying aqueous liquids is prepared by the calcination of double-hydrated dolomitic lime to the stage at which substantially all the magnesium hydroxide has been converted to magnesium oxide but no appreciable amount of the calcium hydroxide has been converted to calcium oxide.  The material is prepared by treatment at a temperature between 300 and 700 DEG  C. for at least ten minutes.ALSO:Silica and fluorides are removed from water and aqueous solutions by the addition of double-hydrated dolomitic lime which has been partly calcined, preferably to the stage at which substantially all the magnesium hydroxide has been converted to magnesium oxide but no appreciable amount of calcium hydroxide has been converted to calcium oxide.  The sludge formed in the process when applied to softening water is allowed to accumulate and is agitated with the water and added treating material.  The material is prepared by treatment at a temperature between 300 and 700 DEG C. for at least ten minutes.ALSO:In the purification of sugar juices normally treated with ordinary lime the substitution of a double-hydrated dolomitic lime which has been partly calcined assists in the removal of impurities simultaneously with the precipitation of the lime. The double hydrated dolomite is calcined to the stage where substantially all the magnesium hydroxide has been converted to magnesium oxide but none of the calcium hydroxide has been similarly converted.

Abstract: 713,866. Electromagnetic relays. WESTING- HOUSE BRAKE & SIGNAL CO., Ltd., and KING, K. G. Sept. 25, 1952 [Nov. 30, 1951.], No. 28125/51. Class 38(5) [Also in Group XXXV] In an automatic voltage control system in which the output 'of a push pull magnetic amplifier controls electromagnetic relays controlling a regulator motor, the relays are provided with centre-tapped coils shunted by rectifiers so that they respond only to outputs of the required polarity. A control signal is applied at 21, 22 to the opposed control windings 7, 8 of the transductors 1, 2 which also have self magnetized windings represented at 9, 10, and pre-set bias windings 5, 6. The transductors control the outputs of rectifiers 11, 12. Rectifier 11 energizes the left hand operating coil of each relay, the two being connected in series. Rectifier 12 similarly energizes the other coils which oppose the first coils. Rectifiers 27. 28 are connected across the outer terminals of each relay, so that if one rectifier, e.g. 12, has a higher output than 11, rectifier 28 blocks so that the current in the left hand coil of relay 14 is reduced, whilst the current in the right hand coil is increased, and the relay is operated. In a modification, Fig. 1 (not shown), the pre-set bias windings are connected in parallel with a potentiometer, the slider which is connected to the mid-point of the winding so that the two transductors can be adjusted for balance; the self magnetizing windings are connected across rectifiers which are in series with the A.C. windings; and the output relays control further contactors which are arranged for inching the regulator when the voltage is approaching its proper value. This is achieved by a further control winding on each transductor energized in such a direction as to oppose the signal whenever either one of the relays is operated.
