Title: Improvements in inking mechanism for printing machinery
IPC: B41F31/03
Filed: 1929-05-06
Abstract: 332,320. Claybourn, L. W. May 6, 1929. Inking-apparatus. - In an inking-apparatus, particularly for applying inks containing metal powder or other heavy colour constituents, the ink reservoir is provided with a rotary ink-agitating drum which keeps the ink in a thoroughly stirred condition and has an ink-retaining periphery from which the ink is transferred to the distributing-rollers of the apparatus. The apparatus may form an attachment to an inking- mechanism of the construction described in Specification 293,332 but may be independent of the usual inking-mechanism and may be applied to a flat-bed machine. One or more reservoirs 21, Figs. 4 and 6, may be provided, adjustable laterally of the machine and secured in position by bolts 65. Each reservoir contains a rotary agitating drum comprising a shell 25, Figs. 4, 6, and 7, provided with undercut longitudinal slots 28, and having pin and slot connection with end discs 112, Fig. 7, which are secured to a central sleeve 109. The spindle 102 of the drum is operatively connected with the sleeve 109 by a pin and slot connection 101 which allows the spindle to be withdrawn upon removing an end nut 107 to allow removal of the drum for cleaning purposes. Spaced from the drum is a composition-covered roller 32 which is similarly removably mounted on its driving spindle. 118. Ink is transferred from the periphery of the drum to the roller 32 by transfer members comprising discs 31, Fig. 6, connected by a shank 34. The transfer members rest freely upon the drum and roller and are free to move axially. A series of transfer members having discs 31 of different widths are provided to allow of adjustment of the amount of ink applied to the roller 32. A modified construction of ink-transfer member is shown in Figs. 12 and 13 and comprises, in addition to the discs 31, radially movable quadrants 41 which can be held in the inoperative position shown, or in an expanded position in which they act also as ink-transfer surfaces. Spring-pressed balls 49 engage recesses 48 to hold the quadrants in their adjusted positions. The roller 32 contacts with a roller 126, Figs. 4 and 6, in contact with one of the distributing-rollers of the inking-apparatus, and the roller 32 and agitating drum are driven from a gear 75, Fig. 6, on the shaft of the roller 126. This gear 75 drives a gear 81 on the shaft of which is a gear 87 which drives a shaft 89 by means of a gear 88. Splined upon the shaft 89 are as many gears 92 as the maximum number of reservoirs that the machine, can accommodate. When the reservoirs are secured in position, a corresponding number of the gears 92 are moved into engagement with gears 91 on the shafts of the agitating drums and secured to the shaft 89. The rollers 32 are driven from the gears 91 through idle gears 95.

Title: Improvements in Sound Operated Circuit Controller.
IPC: A63H3/28
Filed: 1916-10-09
Abstract: 106,463. Submarine Wireless Co., (Assignees of Berger, C.). May 19, 1916, [Convention datel. Sound, controlling and actuating apparatus by- -In means for controlling an electric circuit by sound waves in which a pendulum-like contact member is momentarily kicked off from a diaphragm against which it normally rests, so as to break an electric circuit when a sound wave vibrates the diaphragm, the pressure of the contacts in relation to the area in contact is so adjusted as to give maximum conductivity so that the normal current is restored with certainty when the sound ceases. The natural frequency of the swinging contact is less than that of the diaphragm. In the applications described, the contacts are in circuit with a normally energized electro-magnet which releases its armature when a sound strikes the diaphragm, and attracts it again when the sound ceases. In one case, the armature, when released, closes the circuit of an electro-magnetic vibrator or bell. In another, the armature, each time it is attracted, moves a ratchet-wheel one step. The teeth of the ratchet are alternately long and short. The long teeth make contact successively with a spring contact in circuit with a motor, which is alternately started and stopped by successive sounds. As shown in Fig. 3, the swinging contact 31 rests against an inclined diaphragm 30, the pressure being adjusted by varying the inclination of the diaphragm. The electro-magnet 42 has two armatures 60, 61 (which serve also as contacts cooperating with the core of the electro-magnet as shown), the armatures being mounted on a disk 59 which swings each time the magnet is deenergized so that the armatures are attracted alternately, and the circuits of devices such as a motor 64 and bell 63 are closed alternately. Fig. 4 shows an application tc an amusement device. The diaphragm 30 is attached to or formed by one wall of a representation of the kennel. The swinging contact 31 has an horizontal arm 35 to give the required pressure. The circuit includes a battery 41, electro-magnet 42, and may include part of the armature 43 which is held attracted against the action of a spring 44. A dog 45 mounted on a sliding or wheeled carriage in contact with the armature is caused to appear through the door 46 of the kennel when a suitable sound, such as a whistle, vibrates the diaphragm and denergizes the magnet 42. The armature is pulled back, again closing the circuit, by a cord 47 and the dog may be replaced by hand. Several diaphragms of different frequencies and with corresponding contacts may be formed in the different walls of the kennel so that the device is responsive to a wider range of sounds. In all cases, the swinging member may, if desired, be arranged to break circuit elsewhere than at the point of contact with the diaphragm.

Title: Improvements in or relating to electric motor control systems
IPC: G05B11/01
Filed: 1947-05-30
Abstract: 637,115. Automatic current control systems. SPERRY GYROSCOPE CO., Inc. May 30, 1947, No. 14459.. Convention date, June 15, 1946. [Class 38 (iv)] [Also in Group XXXVII] In a control system wherein the armature of an electric motor is continuously traversed by current furnished by a generator and the motor torque is primarily controlled by variation of the excitation of its field system, the generator is also so controlled that the current furnished by it to the motor armature is increased in dependence upon the magnitude, without regard to sign, of the motor torque. A followup system comprises a motor-driven generator 5 which supplies the series-connected armatures of two servomotors 1, 6. A signal transformer 9 is unbalanced with respect to a signal transmitter 11 when a load is placed on the motor 1, and an error signal is transmitted through a conductor 12, a phase-sensitive device, and an amplifier comprising valves 13, 14, to the motor field winding 3, so as to counteract the effect of the load on the motor. The motor 1 drives a permanent magnet generator 7 which serves to stabilize the servomotor through negative feedback to the amplifier. The sum of the currents passed by valves 13, 14 is conducted through resistor 17 in the cathode circuit of a valve 18 so that, when the output of the error signal amplifier is increased, the cathode potential of the valve 18 is raised. The placing of a load on the motor 1 causes the resultant increase in the field excitation thereof to decrease the current passing through the armature of the generator 5 and a seriesconnected resistor 19, which is in the grid circuit of the valve 18, and this effect, combined with the raising of the cathode-potential due to the voltage across the resistor 17, renders the valve 18 less conductive and increases the current passing to the generator field winding 24 through a valve 23. The armature current of the servomotor is thus increased with load and this leads to a.reduction in the lag due to load between the reference and follow-up members of the system. The field excitation of the motor 6 is controlled similarly to that of the motor 1. The increase in the armature current of the motor 1 does not greatly affect the motor 6, due to the increase of the backelectromotive force of the motor 1, the stabilizing effect of a permanent magnet generator which is coupled to the motor 6, and the reaction of its own follow-up system. A network 25 is provided to overcome delay in response due to inductance of the generator field and armature circuits.
