Filed: 1920-04-09
Abstract: 152,657. Hoe & Co., R., (Assignees of Schmidt, L. A.). Oct. 11, 1919, [Convention date]. Inking-apparatus.-Relates to inking-apparatus for printing- machines of the general type shown in Specifications 126,815 and 20195/14 in which ink is supplied to a number of separate conduits for delivering an independent supply of ink to different columns or sections of the forme, and comprises means whereby a portion of the ink fed to certain sets or series of conduits may be simultaneously diverted therefrom without affecting th.e supply to other conduits. Improved constructions for the adjustment and operation of the delivery pumps are also described. Ink is supplied to a series of columns &c. by a set of pump plungers 7 reciprocating in ports 6 in a member 4 slidably mounted in guides 5 within an ink reservoir 1 provided with conduits 3 eommunicating with the ports 6 which alternately act as suction and discharge ports as the member 4 is reciprocated. A controlling member 21 having ports 23 and by-pass channels 26 slides between the bottom 2 of the reservoir and the member 4, and is adjustable by a screw 31 rotating in a stuffing-box 30 and engaging a nut 32 so that a predetermined proportion of the ink supplied by the plungers to the conduits 3 may be diverted through the channels 26 back to the reservoir. The plungers 7 provided with collars 8 and end flanges 20 slidably engage holes in a member 9 grooved to receive a shaft eccentrically mounted in the sides of the reservoir and revolving in eccentric straps 13, Fig. 3. The shaft is driven from any part of the machine by gear wheels 14, 15 so that an eccentric motion is given to the member 9 serving to reciprocate the plungers vertically and the member 4 horizontally, the operations being so timed that when the plungers are on their upward strokes the ports 6 communicate with the reservoir, and on their downward strokes with the conduits 3. Stops 16, screwed into the top 17 of the reservoir 1, engage the flanges 20 and may be independently adjusted to limit the extent of the suction strokes and therefore the quantity of ink delivered to the corresponding conduits. Springs 19 fitted between the member 9 and the flanges 20 compensate for this adjustment and lift the plungers on the suction strokes.

Title: Installation for guiding missiles
IPC: F41G7/30
Filed: 1966-03-09
Abstract: 1,141,999. Controlling missiles. NORDAVIATION-SOC. NATIONALE DE CONSTRUCTIONS AERONAUTIQUES. 9 March, 1966 [16 March, 1965], No. 10452/66. Heading B7G. [Also in Divisions F3, G4 and H3] The direction of a spin-stabilized missile is controlled by control apparatus acting in a single plane rotating with the missile and the control signals appropriate to jaw and pitch are applied alternately as the missile spins. Height and direction error signals are supplied to the missile from the ground and are passed from a receiver 4 through a co-ordinate changer such as a commutator having segments 24-27 or a series of photodiodes activated in sequence by a light behind a perforated disc (Fig. 9, not shown). The disc or commutator is held against rotation by a gyroscope so that their yaw and pitch axes are fixed while the brushes 33-36 and apparatus to which they are connected rotate with the missile. The height and direction error signals are derived by aligning a telescope with the target and measuring the deviation of the missile by means of an infra-red detector. After passing through the co-ordinate changer, the signals are summed with signals from a rate gyro 6 sensitive to angular changes in the plane in which the control apparatus operates. The resultant signal is applied to a sign detector which causes pivoted plates to obstruct part of the engine exhaust on one side or the other. Feedback through the rate gyro causes the signal to change sign repeatedly to give the desired mean control effort. To damp the directional oscillations the rate gyro signal is integrated and the ground supplied signals are differentiated in capacitor-resistor networks (Figs. 4, 8, 9, not shown). The error signals are varied in a stepwise manner by the coordinate changer, and to approximate more accurately to a sinusoidal variation the error signals are fed in through additional parallel resistors, such as 38, 39 connected in circuit by the commutator for overlapping periods of time.
