Title: Improvements in apparatus for automatically and continuously correcting the trainingof guns in accordance with the inclination of the trunnions
IPC: F41G5/16
Filed: 1922-01-30
Abstract: 177,146. Schneider et Cie. March 12, 1921, [Convention date]. Sights and methods of sighting. - R e l a t e s to means for automatically and continuously applying to guns on swaying platforms a traverse correction d in accordance with the known law d = j tan i, where j is the inclination of the trunnion axis and i is the angle of gun elevation. According to the invention, a gyroscope suspended in neutral equilibrium is employed to give a continuous measurement of j and a mechanical or electrical device serves to multiply this measurement by tan i, Fig. 4 shows one arrangement suitable for direct fire, in which the sighting telescope 4, carried by a gyroscope 34, has its cross-wires 2, 3 mounted on a ring 1 forming part of a jointed frame 13, 14, 15, 16, the slotted member 11 of which is moved by a pin 74 to displace the cross-wire 2 and thereby apply the correction d. The pin 74 is mounted on an arm 39 adjustable vertically on a pillar 40 extending from the gymbal ring x of the gyroscope. The movement of the pin at right-angles to its slot is proportional to j and the distance of the pin from the joint 13 is adjusted inversely proportional to tan i. 41 is a spirit level for correcting for precession of the gyroscope by acting on a knob 42 to keep the cross-wire 3 horizontal. In a modification, a separate gyroscope is employed to stabilize the prisms of the telescope so that the target is always kept in the vicinity of the horizontal crosswire. In cases where the training of the gun is controlled from a distant observing station through a Wheatstone, bridge arrangement, the correction may be applied to the zero point of the voltmeter of the bridge.

Title: Improvements relating to numbering mechanism for cylinder printing machines
IPC: B41K3/12
Filed: 1925-01-31
Abstract: 251,347. Zimbel, W. Jan. 31, 1925. Cylinder machines ; number-printing apparatus. -In a cylinder printing-machine, the sheets are numbered as they pass through the machine, by means of numbering-heads e mounted on a rotary carrier c and co-operating with the impression cylinder a, the heads e being reset at each revolution of their carrier c by the engagement thereon with a cylindrical cam f, which can be moved to inoperative position either manually or automatically during the non-printing revolution, or part of a revolution, of the cylinder a. A fixed part z forms, in conjunction with the cam f, a groove in which the resetting-roller runs. The cam f is pivoted to a shaft q which is operated either by a hand-lever p or by a cam m on the shaft of the impression cylinder, a crank i and a spring-controlled rod k, the rod k having at its end a roller k<1> bearing against the cam m. The cam m is designed and timed to act according to the type of cylinder machine with which the numbering-apparatus is employed. As applied to a stop-cylinder machine, in which the sheet usually occupies about one-half of the periphery of the impression cylinder a, the rotary carrier c is geared so as to make two revolutions to each revolution of the cylinder a. As only one of the revolutions of the carrier c is a printing revolution, the resetting-mechanism must be inoperative for one revolution and the cam m moves the cam f to inoperative position during this revolution. When the numbering-apparatus is applied to a two-revolution machine with the sheet occupying practically the entire circumference of the impression cylinder, two carriers c are geared to the impression cylinder and print alternate numbers.

Abstract: 411,965. Epicyclic toothed gearing. ARMSTRONG SIDDELEY MOTORS, Ltd., and VIALE, S. M., Park Side, Coventry. Jan. 31, 1933, No. 2967. [Class 80 (i).] In epicyclic gearing for transmitting the drive between an internal-combustion or other impulse engine and a rotary propeller, the reaction element is held against rotation by springs and automatically forced axially by the propeller thrust to introduce damping between itself and a stationary member. As shown, the annulus 14 secured to the crankshaft 17 drives the propeller shaft 12, which is rigid with the carrier 13, through the planets 19. The reaction sun 21 is in floating toothed engagement with a sleeve 23 bolted to a drum 25 carrying spring-blades 26 engaging between teeth 27 on the casing 31. The propeller thrust urges the thrust-bearing 36 to the right, and thus through a flanged cylinder 38 forces the drum 25 into engagement with the friction surfaces 33, giving frictional damping in proportion to the thrust. Initial damping is produced by a brake 39 pressed against the drum 25 by springs 40.
