Disc 7 is rigidly secured to a rotary plate 6 carrying the rulers 9, 10 and disc 7 and plate 6 can rotate about shaft 4. Disc 7 carries a mounting 17 for a pawl 18 one end of which is engaged by the knob 12 and the other can engage slots 20 in the base plate 1. Depression of the knob 12 releases the pawl 18 from the base plate 1 thus enabling the disc 7 and plate 6 carrying the rulers to be rotated into a new position. For certain predetermined positions (as shown, at 30 degree intervals) the rulers may be locked by releasing the knob so that pawl 18 engages in the corresponding slot ; in intermediary positions the rulers are locked by rotating the knob thus tightening disc 7 and plate 6 into frictional engagement with base plate 1.
Patent GB-110202-A (GB)
Title: Improvements in or relating to Stock or Sheet Registering Devices.
IPC: B65H9/10
Filed: 1916-10-16
Abstract: 110,202. Automatic Printing Machine s, Ltd., (Harris Automatic Press Co.). Oct. 16, 1916. Sheet-registering devices; carriers and forwarders.- Relates to means for registering sheets against a side stop or gauge as they are being advanced to front stops against which they are also registered. In the arrangement shown, the sheets 12 are advanced from a table 13 by a feeder 15 &c. to a series of forwarding-rollers 18, 20 projecting through slots 19 in a table 16. The foremost roller 20 is mounted so that it may be moved endways while it is rotated by the gears 28, 29 This movement is imparted to it by a lever 21 operated by a cam 26 on a shaft 27 driven by gearing 59 &c. from the cylinder 57 of the printing &c. machine. By this endways movement of the roller 20, the sheets 12 as they advance are carried laterally against the side gauge 39 which is normally stationary. The sheets are pressed against the roller 20, and also against the rollers 18 if desired, by balls 38 which rest freely on the rollers, being confined in conical or cylindrical pockets 37 formed in carriers 30 extending longitudinally above the table 16. The balls may be readily changed for others of different weight, according to the thickness or quality of the paper sheets. The front stops 41 are moved laterally simultaneously with the roller 20 by an extension 43 from the shaft 42 on which they are carried. The shaft 42 is rocked to raise the front stops by an arm 51 operated by an arm 53 on a rock shaft 44, and the gauge 39 is also withdrawn from the edge of the sheet while it is fed off, by means of a wedge-arm 48, on the shaft 44, engaging a pin 49 on the rod 40 which carries the gauge. When thin paper is being fed, it is desirable to lift the balls from the rollers while the sheet is fed off. This is effected, as shown, by mounting the ball carriers 30, 31 on pairs of depending swing arms 32, 34 and 33, 35, and rocking the pivot shaft 36 of the arms 34, 35 by means of an arm 54 and a cam 55 on the rock shaft 44. The balls 38 on the roller 20 may be in pairs and placed so as to crimp or bend the sheet 12 where it is moved against the side gauge, as shown in Fig. 8.
Patent GB-932929-A (GB)
Title: Improvements in or relating to bulk density control
IPC: C10B57/08
Filed: 1961-04-24
Abstract: 932,929. Automatic bulk density control. KOPPERS CO. Inc. April 24, 1961 [April 22, 1960], No. 14744/61. Class 38 (4). In a system for controlling the bulk density of pulverized coal transported in a stream, deviations of the density from a desired value, detected by radiation passed through the stream, are corrected by automatically controlling the addition of liquid to the coal. In the arrangement described, coal from a mine or a store is crushed and conveyed to a pair of hoppers which may be supplied with coal of the same or different grades. The hoppers feed continuously operating conveyers, the outputs of which are mixed and the mixture pulverized before supplying it to coke ovens. By means of a scraper a constant depth of the pulverized mixture is maintained on a conveyer transporting it to the coke ovens. Radiation, e.g. gamma radiation from a caesium source 55, Fig. 3, is passed through the constant depth of pulverized coal 44 and the bulk density of the coal measured by an ionization cell 67 associated with a compensating cell 71. The D.C. signal thus produced is converted into an A.C. signal by a converter-amplifier 75 and reconverted to D.C. by a vibratory contact rectifier 121. The output of rectifier 121 serves to charge a condenser 119, while condensers 97 and 113 are charged to opposite polarities from a standard cell 111. Any out-of-balance between the voltages of these three condensers, when bulk density deviates in one sense or the other from a desired value, results in the application of a pulse input of corresponding phase sense to an amplifier 89 so that a valve 131 or 133 is rendered conductive to energize. a winding 101 or 103 of a solenoid motor 93. Operation of motor 93 adjusts a condenser 97 to restore balance, sets a pointer 99 to record bulk density, and adjusts a flapper valve 149 relative to a pneumatic orifice 153. The resulting change in pressure in a conduit 161 is amplified at 159 and controls pneumatic actuators 165, 167 associated with valves 81 and 83 which respectively adjust the supply of water and oil to the mixture before pulverization. The addition of water lowers the density, whereas the addition of oil raises it, the arrangement being such that when bulk density is correct both valves are closed, valve 81 opening progressively if density rises and valve 83 opening progressively if it falls. Restrictions 185, 187 associated with bellows 179, 181 provide differential and integral components of control. Modifications in which density is measured by directing radiation through a constant height of coal on a stationary surface or a constant width of coal being transported, are referred to.

Title: Improvements in remote control electro-magnetic switches
IPC: H01H51/08
Filed: 1932-05-24
Abstract: 403,992. Electromagnetic switches. EVANS, 0., 27, Chancery Lane, London.- (Stotz-Kontakt Ges.; 1, Volta Strasse, Neckarau, Mannheim, Germany.) May 24, 1932, No. 14768. [Class 38 (v).] An electromagnetic change-over switch operated by successive energizations of an electromagnet i has an armature formed of a number of parts, three as shown, the central part e being secured to a sliding rod a carrying bridging contacts b at its ends whilst the outer portions h are loosely mounted on the rod a. A dead-centre spring mechanism k is provided as shown to hold the rod a in one or other of its extreme positions in which it bridges contacts c on contacts d. On energization of the solenoid the central armature part e and one of the outer parts f or g move together towards the centre of the solenoid. At this point the solenoid circuit is arranged to be automatically broken. The kinetic energy of the core part e and contact rod carry the latter across the dead-centre position of the spring mechanism k which then automatically completes the motion of the operating rod causing the opposite pair of fixed contacts c or d to be bridged. The three portions of the core are together equal or nearly equal to the length of the solenoid and the outward motion of the loose outer parts is limited by casings j attached to the solenoid ends, their inward movement being limited by flanges h engaging these ends. Instead of providing separate contacts operated by the movement of the rod a for de-energizing the solenoid when the armature part a is at or about its central position the energization and de-energization of the electromagnet i may be effected at contacts c or d. In this arrangement the energization of the magnet suffices to impart sufficient momentum to the middle and one of the outer of the armature parts to carry the part e beyond the mid position.

Title: Improvements in or relating to electrical plug, socket, and switch combinations
IPC: H01R13/707
Filed: 1920-06-01
Abstract: 168,641. Crabtree, J. A. June 1, 1920. Plug couplings combined with electric switches. Relates to a switch and plug combination in which the contact plug or detachable. part of the electric coupling is removable, leaving the switch-operating member combined with the contact socket or second part of the electric coupling, and in which the switch cannot be closed when the plug is removed, but can be operated when the plug is in position, and consists in an arrangement whereby when the plug is removed the switch-operating member can be actuated in the ordinary manner, that is to say, to the full extent of its normal stroke, without closing the switch. The arrangement may also be applied to the case in which the withdrawal of the plug automatically opens the switch. A disengaging gear is provided in connection with the switch mechanism which disconnects the switch arm from the switch-operating member and is under the control of the plug. The earthing pin a' of the combination illustrated rocks a pivoted cam b and so moves a slotted spring-controlled arm d as to cause a roller k thereon to move the tail h' of the disengaging lever h when the plug is withdrawn, at the same time locking the switch member in the " off " position. The lever h is pivoted upon the switch-operating member l at i and perforated to engage a projection j on the switch member l to couple it to the switch-operating member. In the arrangement illustrated, the withdrawal of the plug effects the opening of the switch.
