Abstract: 1,062,562. Electro-erosion. EXPERIMENTAL'NY NAUCHO - ISSLEDOVATEL'SKY INSTITUTE METALLOREZHUSHCHIKH STANKOV "ENIMS." Aug. 29, 1963, No. 34182/63. Heading B3V. [Also in Division G3] In an electro-erosion machine, the gap between the electrode and the workpiece is automatically maintained at an optimum size by a control system utilizing signals representative of current and voltage across the gap, and means are provided to take account of false signals caused, for example, by the presence of carbonized particles in the gap. As shown, the electrode 2 and the workpiece 3 are supplied from a pulsegenerator over a resistor 4 by way of input terminals 1. Current pulses through the resistor 4 are detected by devices 5, 6 producing signals, limited in amplitude and width and proportional to the current, which are applied to a device 9. Similar signals dependent on the voltage across the working gap are applied to device 9 from devices 7 and 8. At no load there are no current signals and the output from device 9 operates a motor 10 to adjust a potentiometer 11, thereby actuating a regulator 12 and an electrode feed motor 13 which operate to move the electrode 2 towards the workpiece 3. When the electrode touches the workpiece the device 9 receives current signals but no voltage signals, and the electrode 2 is then caused to move away from the workpiece. In normal operation the device 9 receives both current and voltage signals, and the motor 10 operates only when the limiting conditions are effective, whereby the gap size is kept substantially at an optimum value. False current indications which may arise with a small gap are detected by the device 14 which applies a signal to device 9 so that the electrode is caused to move away from the workpiece. Suitable circuit arrangements for the devices 5 to 11 and 14 are described with reference to Fig. 3 (not shown).

Abstract: 1464515 Testing digital circuits HEWLETTPACKARD CO 18 Aug 1975 [3 Sept 1974] 34272/75 Heading G1U In a method of testing a digital circuit the bits occurring at a selected point of the circuit are monitored by evaluating their signature - this being an n-bit check word derived, e.g. by the use of a feedback shift register, from an m-bit word, where n<m. Two modes of operation are possible: either (1) the evaluated signature is displayed and compared with the expected signature, which for convenience may be printed on the circuit diagram at the said selected point; or (2) in order to check for intermittent faults the signature can be evaluated repeatedly each signature being compared with the immediately preceding signature. An appropriate shift register, Figs. 2A, 2B, (not shown) with feedback via exclusive-or gates is outlined, together with a modified register, Figs. 3A, 3B, (not shown) evaluating the same function but incorporating 'look ahead', and overall block diagrams of a complete system.

Title: Improvements in and relating to calculating or accounting machines
IPC: G06C21/04
Filed: 1929-08-09
Abstract: 343,060. Calculating-apparatus. BURROUGHS ADDING MACHINE CO., 2nd Avenue, Detroit, Michigan, U.S.A.- (Assignees of Muller, R. L.; 14041, Glenwood Avenue, Detroit, Michigan, U.S.A.) Aug. 9, 1929, No. 34314/30. Convention date, Aug. 10, 1928. [Class 106 (i).] In a calculating-machine with depressible item keys and a motor operated driving mechanism a control mechanism is provided which is adapted to be controlled by the depression of a predetermined selection of item keys to cause the driving mechanism to operate the machine. The invention is shown applied to the machine described in Specification 317,090, [Class 106 (i), Calculating &c.] in which a proving mechanism is set in a predetermined operation and is adapted to prevent a subsequent operation unless the same keys are depressed in the two operations, the depression of the last key in the second entry causing the machine to operate automatically. In this machine the proving mechanism controls a bail 54, Fig. 2, which is prevented from moving forward unless the second entry of the item agrees with the first entry. The motor operation control mechanism comprises a starting bar B which, on depression, rocks a lever 110 having a pin 114 co-operating with a latch 113 to hold it in the raised position. Such latch is adapted to be freed at the end of an operation by means of a projection 122 on a slide operated by a lever 120 controlled by a pass-by pawl 118 on an arm 116 mounted on the main rock shaft 600. When the paper carriage tabulates to a " proof " column following a total taking operation in the " balance column the rocking movement of the arm 116 is limited by a projection 141 on an arm 140 being set in the path of a stud 142 on the arm by depression of the usual total key. The pass-by pawl 118 does not move passed the roller 119 but a second and shorter pawl on the arm 116 rocks the lever 120, the movement however is not sufficient to release the latch 113. On this account a swinging abutment 130, normally held in an inoperative position by reason of the contact of the pin 114 with an extension 133 of the abutment, is swung into position over a pin 131 on the link 112 controlling the motor clutch so as to prevent it rising. If the correct keys have been depressed in the " proof " column position the freeing of the last of the arms associated with the bail 54 permits a movement of the bail. An arm 145 thereon rocks a bell-crank lever 146 which displaces the abutment 130 and frees the link 112 to start the motor. If the wrong keys have been depressed the bail 54 does not move and the abutment remains operative to prevent movement of the link 112.

Abstract: 882,725. Tar sprayer. AVIATION, MINISTER OF. Feb. 5, 1959 [Nov. 5, 1957], No. 34472/57. Class 107. In apparatus for spraying tar on to a road or like surface the quantity sprayed is varied in accordance with the speed of the vehicle on which the apparatus is carried. Heated tar is pumped from a storage tank via pipe 8 to spraying bars 4, 5 and 6, arranged in series in an elongated S form, by a pump driven from the vehicles' engine. A return circuit to the tank via pipe 9 maintains the tar in circulation when the sprayer is shut off. Each bar is supplied with a series of nozzles 13 controlled by valves 14 and the valves of each bar are operated by arms 15 attached to a central bar 17 which slides transverse of the vehicle under the control of an hydraulically operated ram 18. The control bar 17 associated with spray bar 4, which is the first bar brought into operation and the last to cease operation, closes a valve 20 in pipe 9 when it is moved to open its spraying valves whereby the tar pressure builds up in the spraying bars. This spray bar 4 is brought into operation by manual control of its associated ram 18 and as the speed of the vehicle increases the tar pressure builds up until at a predetermined pressure a tar pressure operated device (Fig. 3 not shown) operates a spring loaded rack and pinion mechanism (Fig. 4, not shown) which operates a valve arranged in the fluid circuit of the hydraulically operated ram 18 attached to the control bar 17 of the second spray bar 5. The bar 5 is thereby brought into operation. If the vehicle speed and hence the tar pressure further increases the third spray bar 6 is brought into operation by a second tar pressure operated device and rack and pinion mechanism. The temperature of the tar is maintained by jacketing the tar feed pipes and spraying bars and circulating hot air through the jackets via pipes 10, 11 and 12. Specification 706,035 is referred to.

Abstract: 778,952. Automatic circuit-breakers; snapaction switches. FEDERAL PACIFIC ELECTRIC CO. Nov. 30, 1954 [Dec. 11, 1953; Dec. 11, 1953; Dec. 11, 1953; Dec. 11, 1953], No. 34706/54. Class 38(5) In order to prevent arcing and welding of the contacts 20, 22 on closing of a manually-operated circuit-breaker, the movement of the contact 20 is temporarily obstructed during the turning of the handle 28, the obstruction being removed shortly before the handle completes its closing stroke so that the contacts snap closed independently of movement of the handle. The obstruction is formed by a member 56 located by a tongue 63 and supported on a movable contact-carrying member 18 pivoted on a helical spring 48, a compression spring 42 being positioned between handle 28 and member 56. As handle 28 is turned from contact open position (Fig. 1) it first drives link 30 to pivot lever 26 into engagement with an overload bimetal 32 and then causes member 18, lever 26, and the bimetal to move as a whole about pivot 48 in the closing direction. The spring 42 presses arm 60 of member 56 so that it travels along a cam surface 68 in the casing until its end engages shoulder 70 thus arresting movement of contact 20. At about dead-centre position of toggle 28, 30 pivot 48 has been slightly shifted and deformed and portion 76 of arm 18 engages the end of a slot in member 56, arm 75 on handle 28 then pushes arm 62 to remove arm 60 from shoulder 70 so allowing contact 20 to snap closed under influence of spring 48. On manual opening of the  breaker, arm 77 on handle 28 engages arm 62 of member 56 to aid spring 42 in driving the contacts apart. The bimetal 32 is connected to terminal 34 and carries the breaker current, the downward flexing of the bimetal in case of overload being aided by magnetization of armature 38 by the bimetal current. Specifications 737,604 and 739,620 are referred to.
