Patent GB-683366-A (GB)
IPC: G06C23/02
Abstract: 683,366. Calculating-apparatus. BEAVIS, E. T. May 3, 1951, No. 10379/51. Class 106 (i). [Also in Group XXXVI] In an electrically-operated calculating machine having a full keyboard, the motor circuit may be completed by depressing any key in a selected denominational order of number keys. The invention is embodied in a machine of the type described in Specification 598,524. In a first embodiment, two or more switches, e.g. 30, 31, Fig. 5, are secured to the machine frame so as to be closed by the zero stops 28 of, e.g. the units and hundreds orders respectively when keys are depressed in these orders. One or the other of these switches is selectively placed in the circuit of a solenoid 47, Fig. 3, by a. further switch 54. Operation of the solenoid pulls a link 62 to rock a lever 60 normally operated by the starting bars of the machine. The lever 60 unlatches a shaft which is rocked by a spring in known manner to close a switch in the motor circuit and release a one-revolution clutch. During the machine operation, a normally-closed cam-controlled switch is opened to break the solenoid circuit and so prevent a further operation due to delayed opening of the switches 30 or 31. In a second embodiment, a single switch 30, Figs. 7 and 10, co-operates with the zero stop 28 of a denominational order selected by moving the switch laterally of the machine. The switch is mounted on an insulating block 72 having three projections engaging in grooves in an insulating bar 73. The switch contacts are connected to three spring members mounted on the projections and normally engaging corresponding conducting strips mounted in the bar 73. A knob 81 secured to the block 72 enables the switch to be disengaged, against the pressure of a spring 79, for lateral movement and carries lugs 85 which co-operate with notches 84 formed on the front of the casing to locate the switch accurately in the selected position. The switch 30 is connected in the circuit of the solenoid 47, as in the first embodiment, but the arrangement is such that, when the switch 30 is withdrawn by the knob 81, both terminals of the motor are isolated from the supply leads. In either embodiment, the switches 30, 31 may be rendered ineffective by actuating a further switch 45, the machine then being started by operation of the usual starting bars. In order to enable the machine to be started by keys in the selected denominational order during a series of subtraction operations, the subtraction bar may be held in a partially depressed position, in which it conditions the machine for subtraction but does not operate the starting mechanism, by a manually-operated latch 69, Fig. 12, which engages a notch 65 in the stem of the bar 25. To facilitate the performance of occasional subtraction operations when the key-controlled switches are operative, the subtract bar may be provided with an extension adjacent to the units order keys to enable it to be depressed simultaneously with one of those keys.

Abstract: 757,817. Roller loading means. SCHIESS AKT.-GES. April 6, 1954 [April 10, 1953], No. 9996/54. Class 120 (2). A spring-loading device for twin pressure rollers for drawing heads of textile spinning machines consists of a first pressure roller pair power coupled to and maintained axially parallel with a lower roller by means of a first holding member mounted solely on the lower roller; a second pressure roller pair power coupled by means of a second holding member to an opposed lower roller, one of the holding members being provided with guiding and hold. ing means for the other whereby the latter is maintained axially parallel to the lower roller upon which it is mounted and so that the two holding members are coupled together and secured against rotation; and a member, loaded by spring means, extending between the two pressure roller pairs so as to form a closed loading system. In the arrangement shown delivery roller 1 and feed roller 4 carry holding members 3 and 5 respectively the latter being connected by a rigid rod 6 fixed to the holding member 3 but free to slide through the member 5. Two pressure roller pairs 7 and 8 respectively are opposed to the lower rollers 1 and 4 and are held in position by a bar 11. The bar 11 is under the influence of a pair of tension springs 12 mounted in the holding member 3 and acting on the bar 11 through rods 13 and an eccentric 15, the latter being rotatable about a bolt 14 to relieve the loading on the upper roller pairs. A yieldable pin 20 is provided to assure that the pressure roller assembly remains in position when the springs 12 are detensioned. The guide rod 6 allows relative movement of the holding members 3 and 5 so as to alter the length of the drafting field. This adjustment can be made by a cross shaft having a helical gear thereon in engagement with a fixed nut in engagement with a screwed portion of the rod 6. Several sets of rollers can be simultaneously adjusted by the one cross shaft. Similarly the part 14 carrying the eccentric 15 may be extended over the whole length of the machine so that when it is rotated the tension of all the springs 12 can be varied simultaneously in all roller sets.

Title: Positioning control system
IPC: B23Q23/00
Filed: 1978-11-15
Abstract: In a wood working machine having a work bed movable relative to the frame of the machine by a screw threaded spindle theres a problem of accurately positioning the bed. Inaccuracy in positioning occurs because of backlash in the drive and also because of overrun occurring on stopping the n drive motor to the spindle. The present invention provides a step motor for driving the spindle and involves (i) initially transmitting n pulses to the motor to rotate the spindle in such a direction and by an amount sufficient to take up backlash, (ii) transmitting thereafter a number of pulses corresponding to the nominal value of the desired movement of the bed to the motor to rotate the spindle and thereby move the bed in a desired direction, and (iii) transmitting thereafter, at a lower rate, n pulses to the motor to rotate the spindle in the opposite direction to that in (i) above and at a sufficiently lower speed to avoid overrun. <IMAGE>

Patent GB-2035381-A (GB)
Title: Two-stage carburization of low- alloy steels
IPC: C23C8/22
Filed: 1978-11-24
Abstract: In the first stage the steel is precarburized in a carburizing atmosphere having a carbon potential of less than Acm to produce a carburized case having a eutectoid or hypereutectoid composition, after which the steel is cooled to transform the case into a bainite, pearlite or martensite structure. In the second stage carbides in a spheroidal or spherical form are produced in the case by heating the pre-carburized steel to a carburizing temperature for a sufficiently long time and with a sufficiently slow rate of temperature increase e.g.  NOTGREATER 20 DEG C ¦ min in the temperature range from the Ac1 temperature to the carburizing temperature, and with the carbon potential in the carburizing atmosphere maintained above Acm when the temperature is above Ac1. Experiments described show that the method is most appropriate for low alloy steels having a carbon content of 0.5% or less in order to achieve a case with 30% or more by volume of carbides within a region between the case surface and 0.4 mm depth.
